Definitions
- the present invention relates to a device for lifting of a frame and, if necessary, part of construction based on this framework, in particular a roof, relative to the underlying walls, intended to be used in multiple copies spread around the frame.
- This embodiment of a lifting device a roof has the drawback of being complex, expensive to manufacture, long and tedious to fix and adjust to the surface of a wall, long to dismantle after lifting the roof up to a chosen level and completed the wall up to the roof thus raised, and particularly harmful to the appearance of the wall since it is necessary to drill into it many holes to fix the different plates.
- the lifting device described in this document includes all the features of the preamble to the claim 1.
- the "support means" of this lifting device constituted by the lower part of lifting towers in vertical support on the ground, are certainly in contact with the wall of the building and therefore likely to be attached to a substantially vertical surface, in particular external, of a wall: however, it is clear that the supporting forces are taken up by the ground and not by the vertical wall.
- the said lifting is relatively bulky because it is supported over the entire part of the ground surrounding the building, the roof is to be lifted.
- the present invention offers a device of the type indicated in the preamble, characterized in that the support means comprise a plate wall common to the guide means and to the controlled means thrust, and common means of connecting means guide and controlled means of thrust with the plate mural, ensuring an identical orientation.
- a device according to the invention can find its application in the lifting of any type of frame, possibly naked but most often wearing part of construction, which will usually consist of a roof as described in the aforementioned French patent application, but may also consist of another component of a construction, such as a floor, in which case the term "lifting" should be interpreted in a broad sense, implying not only an elevation movement but also a downward movement.
- the choice of surface vertical of the walls on which the plates will be fixed of the various devices according to the invention will be carried out depending on the nature of the frame and the part of the construction it carries, an external surface being most often chosen in the case of a roof and an interior surface in the case of a floor.
- connection means comprise means for adjusting said identical orientation.
- connection means have a support plate for guiding means and controlled means of thrust in an orientation identical and means of articulation of the retaining plate relative to the wall plate, around an axis likely to be arranged substantially horizontally and substantially parallel to said surface, as well as, preferably, means for temporarily immobilizing the holding plate by compared to the wall plate, in a determined range of relative angular positions around said axis.
- the support means comprise an intermediate template of fixing the wall plate to the wall surface, susceptible to be attached to said surface and to receive removable the wall plate in a relative position determined. It may indeed be easier to position rigorously then attach to the wall, keeping the setting rigorous obtained, such a template which can be lighter and easier to handle than the wall plate, before placing it on this template.
- such a template allows to fix a wall plate opposite of an area of a wall which, in itself, does not present a sufficient mechanical strength to allow attachment direct, by authorizing a postponement of fixings to areas more resistant to the wall, such as high and low chains or posts, if, according to a preferred embodiment, the template is likely to be attached to the surface of the wall at minus a location offset from the wall plate occupying said determined relative position.
- remote control means both means associated with a single source of fluid pressurized hydraulics or electricity, respectively, connected respectively by a bundle of hydraulic lines or electric cables to the different cylinders, only radio control means acting on autonomous cylinders as for the supply of hydraulic fluid or electricity, respectively.
- the means push commands can be used to lift the frame in a single operation on the entire desired height, and then be used to maintain the frame at the level reached during all the time necessary at the height of the wall up to this level.
- the controlled means of thrust are independently removable guide means which can thus be left in place to perform their function after a certain run lifting of the frame, when the desired level is reached, to allow to permanently dismantle the means commanded to push and assign them to another job site.
- the device according to the invention comprises means, independent of thrust means, for the temporary immobilization of the console at least one level of lift determined from to the common means of connection.
- the means of temporary immobilization of the console advantageously include immobilization means provisional of the guide rod, at least in number one, against a translation in said direction compared to the common means of connection.
- connection means for example constituted by the aforementioned holding plate or in the wall plate, this which, at the same time, produces a temporary immobilization particularly effective, simple to carry out then to undo, and requires few additional organs, in practice a single pin engaged in suitably selected holes guide rods and, simultaneously, in the holes of the connection means or wall plate.
- the console then being mounted in translation in said direction on the guide rod, at least one, the means of immobilization the console may advantageously include means of temporarily immobilizing it against of a translation in said direction relative to the guide rod, at least one in number.
- this temporary immobilization can also be done for example by keying, by means of holes distributed along the guide rod and holes provided in the console, in conditions of simplicity and efficiency analogous to those that have been previously described.
- At least one guide rod is fixed in translation relative to the common connection means, provision may be made for the guide rod to bear integrally, opposite common means of connection by compared to the console and at a distance common means of connection compatible with a predetermined maximum stroke for lifting the roof, a connection box with tie rods for connection to the connection box of at least one other lifting device.
- This arrangement allows connect all or part of the guide rods together devices according to the invention, distributed around a framework to be lifted and, in particular, to constitute by means a static belt connecting each other guide rods of all these devices, above the frame and the construction part which it carries, and creating with these guide rods and with the walls, by through the wall plates, a rigid set of perfectly determined geometry, in which the rods of guide remain well parallel to each other to avoid any application of tensile or compressive stress to the frame as the consoles go up along guide rods, and thus avoid any deformation, or any damage to the frame and the part of construction it carries.
- Such a static belt is particularly effective in the case of four-roofs sides, where it is easy to arrange all tie rods horizontally to make it a rectangular frame, being understood that it can also be used in the case of other roof conformations.
- the console includes mechanical connection means with the console of at least one other lifting device, for example in the form of at at least one cantilever arm, perpendicular to said orientation and likely to be placed in the extension the arm of the console of another lifting device, in a substantially horizontal alignment and substantially parallel to said surface, and rigidly connected to this other arm by a rectilinear beam disposed along said substantially horizontal alignment.
- the rectilinear beam thus connecting the brackets of two lifting devices according to the invention, in practice two neighboring consoles, can take support under the frame in the same way as the consoles themselves, know between them, which allows to distribute the supports of the frame and therefore to avoid deformations of it between supports.
- any console includes means for adjusting the level of said arm, at least one in number, in said direction.
- each console can have two of these arms, respectively on either side of the guide means, which allows have this continuity of support on a part also as large as possible from the perimeter of the walls.
- the console includes means for adjustment of the level of this connecting device according to said direction and / or orientation adjustment means of this connecting device around an axis oriented along this direction.
- the console further includes means for adjusting the orientation of said arms, at least one in number, around an oriented axis following said direction, and providing two arms as well likely to be placed at 90 ° to each other, in particular, one can also form such a belt dynamic support on the entire perimeter of the roof.
- the console includes means of adaptation to the conformation of the structural element that it must carry, these means of adaptation being advantageously suitable for allowing the use of a lifting device according to the invention not only at the bottom of the slopes of a roof or under a floor but also on gable walls, in the case of roofs with two slopes, or on cross walls.
- the support of the consoles, arms cantilevered from these, parts connecting mutual ⁇ these arms, and the aforementioned means of adaptation, under the frame can be direct if the conformation of the frame lends itself to it, just as it can be indirect and take place through rigid beams running along, in the example of roofs whatever they are, breakdowns sand pits and, in the case of two-slope roofs, the crossbowmen.
- this support can be carried out by through a cushion of an elastically material compressible such as natural or synthetic rubber, it providing flexibility to compensate for tolerances in the geometry of the frame, in the positioning of the lifting devices and their synchronization.
- the invention also relates to an embodiment more elaborate, in which the lifting device is arranged to allow level adjustment, while simplifying the general structure of the device, in order to reduce its weight and the manufacturing cost.
- lifting device further comprises adjustment means plumb according to the aforementioned identical orientation of the means of guidance and controlled means of thrust, and means of level adjustment, said plumb adjustment and level linking support means to common means of connection.
- level adjustment means allow thus very precise positioning of the guide means and thrust of each lifting device, ensuring perfect verticality of these means, so that the lifting proper can be achieved with total reliability by the simultaneous use of all the lifting.
- the support means comprise a intermediate support plate mounted to slide in a substantially vertical direction in an integral slide of the wall plate, said intermediate plate having means for fixing the plumb adjustment and level. Sliding mounting of the intermediate plate in particular allows precise initial adjustment of the base height of the support means, and the intermediate plate support made independent of the wall plate also simplifies the assembly and disassembly of the device.
- the intermediate plate support is suspended by a threaded rod from a cross the wall plate, so as to allow fine adjustment of height for said intermediate support plate, and the wall plate has a bracket above allow direct support of said wall plate on a wall chain.
- the fixing means are arranged to allow pivoting of the adjustment means around an axis capable of being arranged horizontally and parallel to the wall surface.
- the common means connection include a holding plate on which the guide means and the controlled means are supported thrust, and that this holding plate is crossed by the plumb and level adjustment means, presenting in particular of the associated oblong passage openings authorizing the angular deflections corresponding to the plumb and level settings.
- the plumb and level adjustment means have an axis threaded on which an adjustment sleeve is screwed.
- the threaded axis of the means of plumb adjustment is integral with a cylindrical head received in a hollow profile forming the associated fixing means of the intermediate support plate
- the threaded axis of level adjustment means is integral with a hinge head articulated connection to the intermediate plate of support by a tenon which crosses squares forming the associated fixing means of said intermediate plate support.
- each adjustment sheath has an end head passing through the openings aforementioned oblongs and forming an operating member for make the corresponding settings.
- the devices according to the invention denoted 63, used in all number required to distribute the lifting efforts as well as possible, advantageously comprise an identical wall plate 1 and an identical holding plate 42, which will be described in first place with reference to Figures 1 to 3.
- the plate wall 1 has a vertical plate 2 for fixing to the wall 3, this plate 2 being delimited by two flat faces 4, 5, mutually parallel and vertical, the first of which is attached to an approximately vertical surface 112, notably but not exclusively an exterior face of the wall 3.
- These two faces 4, 5 are for example square, and connected mutually by a song 6 presenting two zones vertical, or vertical edges of plate 2, and two areas horizontal, or horizontal edges of plate 2, usable advantageously to adjust the orientation and level of the wall plate 1 when it is fixed to the wall 3, such so that the horizontal edges, respectively upper and lower, plates 2 for fixing the plates 1 corresponding to all of the devices according to the invention distributed around a roof are respectively arranged along the same horizontal plane.
- Fixing the plate 2 to wall 3 is removable and for example provided by screwing through holes 7 passing right through it, perpendicularly at its faces 4 and 5, and arranged for example at four corners of the plate 2.
- side 5 applies in its entirety on the surface 112 and is thus fixed there, but in the case of a device 63 implanted near an angle coming out of wall 3, it may not apply and be fixed on the surface 112 only over part of its extent, and apply and also be fixed on an angle 113 extending this and itself fixed to the wall 3, as illustrated in Figures 4, 5, 7.
- plate 2 can also be fixed to wall 3 via a accessory or fixing template 115, illustrated in the figure 12 which distributes the load on the wall plate 1 and, through it, the entire device 63 and the corresponding part of the roof to be lifted, on more mechanically resistant areas, especially on the high chain and, according to a variant, the low chain of the wall, or on poles of it.
- a accessory or fixing template 115 illustrated in the figure 12 which distributes the load on the wall plate 1 and, through it, the entire device 63 and the corresponding part of the roof to be lifted, on more mechanically resistant areas, especially on the high chain and, according to a variant, the low chain of the wall, or on poles of it.
- Figure 12 illustrates two alternative embodiments of the fixing template 115, one of which is shown in solid line and the other has, compared to the first, complements illustrated in dashed line, the gauge 115 being in both cases produced under the form of a rigid flat mesh, for example metallic or composite material, in particular defining a flat face 208 by which the template 115 is attached flat to the surface 112 from wall 3, in a determined position of use in which it is removably attached to it and in which the template 115 will now be described.
- a rigid flat mesh for example metallic or composite material
- the template 115 comprises two rectilinear uprights 116, mutually parallel, vertical and respectively attached to the surface 112 of the wall 3 if one refers to the predetermined position of use of the template 115.
- the two uprights 116 have an upper end section 117 respective placed at a level higher than that of the wall plate 1 and intended for fixing template 115 to the top chain of the wall 3.
- the two uprights 116 are pierced, in their upper end section 117, with 118 holes for fixing screws to the chain top, which holes are provided in several copies distributed along each of the sections 117, in the direction of the height, and oriented perpendicular to the face 208 of the gauge 115, defined in particular by the two uprights 116.
- each upright 116 further presents a lower end section 119, which is intended for lean freely, flat, against the face 112 of the wall 3.
- the two uprights 116 have intermediate sections 120 braced by two sleepers horizontal, respectively greater 121, to the junction with the upper end sections 117, and lower 122, at the junction with the end sections lower 119, and by a strut 123 connecting the junction of one of the uprights 116 with the upper crossmember 121 at the junction of one of the other uprights 116 with the lower cross member 122.
- the strut 123 and the two crosspieces 121, 122 define with the two uprights 116 the flat face 208 attached flat to the face 112 of the wall 3 when the template 115 is fixed against the latter, as well as another planar face 209 parallel to the face 208 and consequently oriented identically to the face 112 of the wall 3.
- the two crosspieces 121 and 122 are spaced, vertically, from a distance close to that which separates the horizontal edges, respectively upper and lower, of plate 2, and each of them carries integrally, in protrusion on the face 209, a respective horizontal slide 124, 125, defining with this face 209 a horizontal groove respective 126, 127.
- the groove 126 corresponding to the upper cross member 121 is open downwards and the groove 127 corresponding to the lower cross member 122 is open upwards, the two grooves 126, 127 also being open on both sides in a horizontal direction parallel to the face 209 of the template 115.
- the two grooves 126, 127 are positioned, one with respect to the other, and dimensioned so that we can introduce it, by a horizontal slide parallel to the face 209 and without play, with the exception of a functional play allowing a such sliding respectively a marginal area of the plate 2 adjoining the upper horizontal edge thereof as well as this upper horizontal edge itself and an area edge of plate 2 adjoining the horizontal bottom edge of it as well as this horizontal edge itself, then that the face 4 of the plate 2 is vertical and slides, flat, against the face 209 of the template 115.
- the grooves 126 and 127 retain plate 2 against movement in all directions except a horizontal direction parallel to face 209, in particular in a position of the plate 2 illustrated in phantom in Figure 12, position in which its upper and lower edges are horizontal, its vertical edges are mutually symmetrical by compared to an unreferenced average plane of the gauge 115, which is vertical and forms a plane of mutual symmetry for two uprights 116, and its face 4 rests flat against the face 209 of the template 115, between the two slides 124 and 125, being parallel to the face 112 of the wall 3 due to the conformation and orientation of grooves 126 and 127, and more precisely rests flat against the intermediate sections 120 of the two uprights 116, against the two crosspieces 121 and 122 and against the strut 123 which thus ensure an intermediary for supporting the plate 2 flat against the face 112 of the wall 3.
- the two slides 124, 125 have holes 128 arranged identically to holes 7 so that when the plate 2 occupies the position illustrated in Figure 2, each of these holes 128 coincides with a respective hole 7 of such so that we can engage in the coincident holes a pin or other immobilizer removable from the plate 2 relative to the slides 124 and 125.
- templates 115 allows the plate 2 to be arranged in locations of a wall 3 which do not in themselves present the mechanical resistance necessary for direct anchoring of this plate 2 by screws engaged in the holes 7 thereof.
- templates 115 can be made in a lot form lighter than wall plate 1, and can be therefore much easier to be rigorously positioned so that grooves 126 and 127 are horizontal before being fixed to the wall 3, positioning rigorous of wall plate 1 then simply resulting of the engagement of its plate 2 in the two grooves 126 and 127 before it is immobilized therein by pinning, or analogous, coincident holes 128 and 7.
- the other variant of the template 115 illustrated in Figure 12 shows the elements of it which just described but the lower end sections 119 of the two uprights 116 extend vertically, simply shown schematically in phantom in the figure 12, to the level of a lower chain not shown in the wall 3, being rigidified by horizontal crosspieces and oblique struts, fully comparable respectively at crosspieces 121 and 122 and at strut 123.
- the lower end sections 119 thus extended present, at a level corresponding to that of the low chain from wall 3, holes at all points comparable to holes 118, distributed like these in the direction of the height, for receive fixing screws to the bottom chain of the wall 3.
- This attachment is added to the attachment to the top chain thereof, which stiffens the support of the wall plate 1 on the wall 3 through the template 115.
- the plate 2 On its face 5, the plate 2 has integrally, cantilevered, a flat, horizontal cradle 8, propped opposite of the wall plate 1 by gussets 9 and struts 10 and also part of the wall plate 1.
- the cradle 8 When viewed in plan, i.e. in a direction vertical, the cradle 8 has a generally rectangular shape, one of whose long sides is defined by its junction with the face 5 of the fixing plate 2 and of which the others sides are defined by an edge 11 formed of planar facets, vertical and perpendicular two by two, not referenced.
- the cradle 8 Downwards, the cradle 8 is delimited by a lower face 12 of indifferent shape, for example planar and horizontal while, upwards, it is delimited by a upper face 13 which, while having a conformation general flat and general horizontal orientation, has a concave shape which will now be described.
- this upper face 13 has the shape of a plane, horizontal, delimited edge 14 on the one hand by the edge 11 and on the other hand by a shoulder 15 parallel to song 11, that is to say defined like him by plane, vertical and perpendicular facets two to two, and like him defining a rectangular plane with the side 5 of the wall plate 1.
- the shoulder 15 is connected to the edge 14 up while it connects down to three sides 16, 17, 18 of the upper face 13 by defining a rim around the assembly formed by these panels 16, 17, 18 with face 5 of the wall plate 1.
- Pan 16 is flat, horizontal, and runs along side 5 of the wall plate 1.
- pan 17 which has meanwhile a concave shape, and more precisely the shape of a part of cylinder of revolution around an axis horizontal 19, parallel to face 5 of wall plate 1 and located on the same side of it as the cradle 8, above of it.
- the angular development of pan 17, in reference to axis 19, is less than 180 °, and for example of around 45 °, evenly distributed on both sides of a vertical plane 20 including axis 19, i.e. also parallel to side 5 of wall plate 1.
- Pan 17 so also when viewed in plan, a shape rectangular with a large side defined by its connection with pan 16, along one long side of it, and the two short sides by its connection with the shoulder 15.
- the pan 17 is connected to the pan 18 which is planar and coplanar with pan 16, and presents, when is seen in plan, a rectangular shape with a large side is defined by its connection with pan 17 while the other long side as well as the two short sides are defined by its connection with the shoulder 15.
- the cradle 8 In a vertical plane 21 perpendicular to the axis 19 and to plane 20 and constituting a plane of symmetry for the wall plate 1, i.e. for mounting plate 2 and the cradle 8 thereof, as well as for the device lifting according to the invention considered as a whole, the cradle 8 has a notch 22 opening into its edge 11 as well as in its lower 12 and upper faces 13 but not reaching the wall plate 1.
- the notch 22 is delimited by two lateral flanks 23, planes, vertical, mutually parallel and mutually symmetrical with respect to the plane 21, which flanks 23 are connect to edge 11 in the direction of a distance by relative to face 5 of wall plate 1, perpendicularly to this face 5, to the lower face 12 downwards and at the edge 14, at the shoulder 15 and at the pan 18 upwards.
- both sidewalls 23 are connected to the same sidewall 24 at the bottom of notch 22, which is concave and semi-cylindrical revolution around a vertical axis 25 located in the plane 21 and passing at least approximately through the junction between the sides 17 and 18 of the upper face 13 of the cradle 8.
- This bottom flank 24 thus connects downwards to the face lower 12 and upwards in pan 17 of the upper face 13, approximately on the half of the dimension that this pan 17 is perpendicular to face 5 of the plate wall 1, from the connection between panels 17 and 18.
- the cradle 8 is drilled right through, that is to say between the pan 17 of its upper face 13 and its lower face 12, of two lights 27 delimited by an inner peripheral face respective 28 cylindrical of revolution around the axis 26 respective, with a diameter approximately equal to the dimension that the pan 17 presents perpendicular to the side 5 of the wall plate 1, between its connections respectively with pan 16 and with pan 18.
- the face 5 of the plate fixing 2 has removable fixing means for two mutually symmetrical yokes 29 with respect to plane 21, for example in the form of respective vertical slides 30 receiving screeds 29 vertically sliding on along face 5 of the fixing plate 2.
- Two stops not shown limit the sliding of the yokes 29 towards the down, so that they stay spaced up, from the upper face 13 of the cradle 8, and holes 31 are arranged in the fixing plate 2 and pass through it side by side, between its faces 4 and 5, to receive pins not shown of removable immobilization of clevis 29 against sliding upwards in the slides 30.
- the yokes 29 occupy the fixing plate 2 a determined position, in which they will be described.
- Each yoke 29 has a flat, vertical core 32, attached to face 5 of wall plate 1 and cooperating with the slides 30 for guiding the yoke 29 at vertical sliding relative to the fixing plate 2, and two wings 33 also flat and vertical, but perpendicular to the core 32 and to the face 5 of the plate attachment 2, so as to be cantilevered above from the upper face 13 of the cradle 8, being spaced apart this upper side up as we said more high.
- the two yokes 29, mutually symmetrical by with respect to plane 21, are respectively symmetrical by relative to a respective unreferenced plan, parallel to this plane 21 and including the axis 26 of a respective light 27.
- the two wings 33 of each yoke 29 are mutually symmetrical about a plane including the axis 26 of the inner peripheral face 28 of a light 27 respective, which plane is perpendicular to axis 19.
- Each of the wings 33 is dimensioned so as to intersects axis 19 and is present mainly above from it, a respective light 34 passing through it right through right parallel to this axis 19.
- Each of the lights 34 which are mutually identical, presents the shape of a portion of ring of revolution around the axis 19, with an angular development which, in the example illustrated, is of the order of 120 °; however, this figure is indicated as a nonlimiting example.
- the lights 34 of the two wings 33 of the same yoke 29 receive and guide, with respect to a rotation around the axis 19 with respect to the yoke 29 and therefore by compared to wall plate 1, a straight pin 35 axis 36 parallel to axis 19 and thus shifted upwards relative to this one.
- the two pins 35, corresponding to the two yokes 29, are mutually independent, but a skilled person will understand, at the reading the rest of the description, that they are in fact coaxial when in use.
- the two pins 35 are immobilized against sliding in parallel to their axis 36 or to the axis 19 relative to the wings 33 of the corresponding clevis 29 respectively, for example at means of appropriate shoulders, bearing on the wings 33 around the lights 34, but their mounting is removable, each of them being for example produced by assembly of several parts screwed mutually along the axis 36, in a manner not described in detail but easily understandable by a skilled person.
- the retaining plate 42 has a structure which will now be described.
- This holding plate 42 is intended to take support on the cradle 8 and has for this purpose a plate support 43 intended to be housed partially between the shoulder 15 of the cradle 8 and the face 5 of the plate attachment 2 with limited relative tilting possibility around axis 19, intended to allow adjustment of horizontality of plate 43 in case a defect in the verticality of the wall 3 would cause a defect in the verticality of face 5, a horizontality adjustment of axis 19 resulting in turn from above-mentioned horizontal adjustment of the upper zones and lower edge 6 of fixing plate 2.
- the support plate 43 has a planar upper face 44 and horizontal, of general rectangular plan defined by its connection to a vertical edge 45, connecting as for him down to a underside 46 which certainly presents a rectangular plane identical to that of the upper face 44 but is not planar, and more precisely has a conformation in relation to that of sections 16 to 18 of the upper face 15 of the cradle 8 in order to provide guidance mentioned above with respect to the relative tilting around the axis 19.
- the shape of the support plate 43 in plan, that is to say the shape of its upper 44 and lower 46 faces, in plan, is substantially identical to the shape, in plan, that the shoulder 15 of the upper face 13 of the cradle 8 defined with the face 5 of the fixing plate 2, however with slightly lower so as to spare with the edge 45 of the plate support 43 and the assembly formed around sections 16 to 18 by the shoulder 15 and the face 5 of the fixing plate 2 a functional clearance which may be less than 1 mm.
- the lower face 46 of the support plate 43 also has three sides 47, 48, 49 of which the first and the last are planes, mutually coplanar, parallel to face 44 and arranged respectively on either side of the second, which presents a convexity in relation to the concavity of the pan 17 of the upper face 13 of the cradle 8.
- the pan 48 has the shape of a part of cylinder of revolution about an axis which, when the retaining plate 42 cooperates with the wall plate 1, merges with axis 19 so that it has been designated by the same reference number.
- Pan 48 thus presents a identical diameter to that of pan 17, but its development angular is slightly higher, for example of the order of 60 ° and each of the sections 47, 49 present between its connection with the pan 48 and the edge 45 of the support plate 43 a dimension respectively smaller than that of pan 16 between the pan 17 and the face 5 of the fixing plate 2, and to that of pan 18 between pan 17 and shoulder 5, so that, when the holding plate 42 is in service, it rests by pan 48 on pan 17, with tilting guide relative around the axis 19, and its sections 47 and 49 are placed opposite sides 16 and 18, respectively, in presenting with respect to these a certain possibility of clearance, authorizing the aforementioned tilting, at during which one of the sections 47, 49 can come into contact with the respectively corresponding pan 16, 18, which corresponds to a limitation of the aforementioned tilting
- the positioning of the yokes 29 relative to cradle 8 is such that there is no contact between these yokes and the upper face 44 of the plate support 43, that is to say limitation of tilting due to of these yokes 29. This positioning is however such that the yokes 29 prevent the backing plate 43 from escaping from the cradle 8 upwards, removable mounting on face 5 intended to authorize the assembly and disassembly of the retaining plate 42 relative to the wall plate 1.
- the plane 21 of symmetry thereof constitutes also a plane of symmetry for him, and the plateau of support 42 present, immediately above the notch 22 of the cradle 8, a notch 50 of the same shape in plan, also symmetrical with respect to plane 21. More precisely, this notch 50 is delimited by two sides lateral 51 planes, mutually parallel and mutually symmetrical with respect to plane 21, from which they are spaced of a distance identical to that which separates from this plane the lateral flanks 23 of the notch 22, so as to extend upwards respectively one and the other of these flanks 23.
- the lateral flanks 51 thus open on the one hand into the edge 45 of the support plate 43 and on the other hand in the face upper 44 of it and in the pan 49 of its face lower 46.
- the notch 50 is further delimited by a concave bottom flank 52, also vertical, to which the side blanks 51 are connected in the direction of a distance compared to their connection with edge 45.
- This flank of bottom 52 is for example cylindrical of revolution around a vertical axis 53 of plane 21, which axis 53 is located on the same side of axis 19 as axis 25 and, depending on the position tilting of the retaining plate 42 around the axis 19 compared to wall plate 1, can be confused with axis 25 or cut it.
- bottom flanks 52 and 24 are identical, so that the flank bottom 52 extends the bottom flank 24 upward when the axis 53 coincides with the axis 25.
- the bottom flank 52 opens out upwards in the upper face 44 of the support plate 43 and down into the convex pan 48 of the underside 46 thereof.
- tapped holes 54 Around the bottom flank 52 of the notch 50 are distributed, at the same distance from the axis 53, tapped holes 54 with respective axis 55 parallel to axis 53, axes 55 being equidistant from it. As will appear later, these tapped holes 54, opening into the upper face 44 at less, are intended to receive fixing bolts, on the support plate 43, of a lifting cylinder arranged as follows the axis 52 and engaged in the notch 50 of the support plate 43 as well as in the notch 22 of the cradle 8 to form a protrusion below the latter.
- each hole 57 and the sleeve 58 which the downward extension are delimited by a peripheral face inner 60 cylindrical of revolution around the axis 56 respective, with a diameter smaller than that of the outer peripheral surface 59.
- the sleeves 58 can be fully or partially closed down, which is the case in the application more particularly described and illustrated, or be open down, which could be the case in this application, described later, if we want to avoid giving the sleeves 58 a dimension important parallel to their axis 56. In the example illustrated, this dimension is such that the bottom of the sleeve 58 either roughly located at the same level as the lower zone, horizontal, from edge 6 of wall plate 1.
- the two sleeves 58 are identical, mutually symmetrical about plane 21, and each of them door by its outer peripheral face 59, in the direction a distance from this plane 21, an eyelet 61 which can be fixed or, preferably, is movable by rotation relative to the corresponding sleeve 58, around an axis 62 parallel to axes 19 and 38 and located approximately at same level as the latter so that each eyelet 61 can receive a respective threaded rod 39, the axis of which 40 then cuts the axis 62 perpendicularly, and that the gold can immobilize the retaining plate 42 against pivoting about the axis 19 relative to the plate mural 1, in a determined orientation corresponding to a rigorous verticality of axes 53 and 56, immobilizing each eyelet 61 on the threaded rod 39 corresponding to the by means of the two nuts 41 thereof, tightened respectively on either side of the eyelet 61.
- the eyelets 61 are preferably removably mounted on the sleeves 58, for example by interlocking, so illustrated but easily conceivable by a skilled person.
- Figures 4 to 8 and 11 illustrate the assembly formed by a wall plate 1 and a retaining plate 42 in various conditions of use.
- various devices of the invention 63 are installed from so that the axes 19, parallel to the face 112 respective due to the application of side 4 of the plate 2 respective flat against it, are horizontal, what an appropriate orientation adjustment is obtained for each wall plate 1 against the face 112 of the wall 3 during its fixing on the latter, and that axes 53 and 56 are vertical even if axes 25 and 26 are not exactly due to a certain defect in the verticality of the face 112 of the wall 3, and which is effected by tilting the tray holding 42 around the axis 19 relative to the plate mural 1, and immobilization in the position obtained by means eyelets 61 and nuts 41.
- each assemblies formed by a hole 57 and the corresponding sleeve 58 integrally receives a straight rod respective coaxial 64, abutting down inside the respective sleeve 58 and projecting upwards, above the upper face 44 of the support plate 43, on a height greater than the desired lifting height for the roof, taking into account that even if we fix the wall plates 1 of the various devices according to the invention 63 as close as possible to the roof, i.e. as high as possible on the walls 3, some components of each of these devices according to the invention 63 must come between the retaining plate 42 and the roof.
- each of the rods 64 is retained against a extraction, upwards, out of the corresponding sleeve 58, as well as against a fall inside this last if open down, by means of one, respective, of pins 35.
- each rod 64 engages between the two wings 33 of a respective yoke 29 and is drilled right through, perpendicular to its axis confused with axis 56, of a hole not illustrated, susceptible to receive coaxially one of the pins 35, engaged by elsewhere in the respective lights 34 of the two wings 33 of the corresponding clevis 29 respectively.
- the shape of these lights 34 allows movement of pins 35 by relative to the wings 33, in relation to the orientation of the axes 56 with respect to the axes 36, during adjustment tilting orientation of the retaining plate 42 around the axis 19 relative to wall plate 1.
- Each rod 64 passes through the roof which, at this point, effect, removed some tiles or slates, and presents above of this roof a respective free end 66.
- Both free ends 66 of the two rods 64 are secured mutually by coaxial socket in a blind bore respective, not referenced, of a connection box or connection 67 specific to these two rods, on which this box 67 can also be fixed by any suitable means, and in particular by pinning or screwing.
- connection box 67 present in the example illustrated the general shape of a parallelepiped rectangle, defined in particular by a flat lower face 68, horizontal, in which the bores are arranged blind, an upper face 69 also flat and horizontal, to which the bores in question are closed, two front faces 70 plane, vertical, parallel to a plane not referenced defined by the two axes 56, and two faces side 71 also flat and vertical, meanwhile perpendicular to this plane and mutually symmetrical by compared to plan 21, as well as rods 64 due to their coaxial mounting in the sleeves 58.
- the two front faces 70 and the two faces lateral 71 each carry, in solidarity, a yoke respective 72, 73 suitable for receiving and retaining, for example by pinning along a respective axis parallel to the axes 56, a rigid tie 74, 75 for connection with the box connecting a neighboring lifting device 63, respectively.
- a tie 74 or 75 for connection with the box connecting a neighboring lifting device 63, respectively.
- the Man trade will choose, on each of these connection boxes, the most suitable screed among the 72 screeds on the faces frontal and the yokes 73 of the lateral faces.
- tie rods 74, 75 connecting together the connection boxes 67 of the various devices according to invention 63 spread around a roof form above from it a static belt, preferably continuous, stiffening at this level the structure in particular defined by guide rods 64, also stiffened by their connection with walls 3, through holding plates 42 and wall plates 1, which allows to maintain a rigorous parallelism of the different guide rods 64 of the various devices 63, on the entire length of these rods 64, that is to say even in their areas furthest from their liaison with walls 3.
- each box of connection 67 and the wall plates 1 of the devices according to the neighboring invention for example between the yoke 72 of the box of connection and rings fixed on the face 5 of the plate of fixing 2 of the wall plate 1 of these neighboring devices, due to a ring near the lower corners of this face 5.
- each lifting device 63 is mounted in translation along the axes 56 thereof, that is to say in translation vertical, a console common to these two rods 64, one of which first exemplary embodiment, referenced 76, has been illustrated Figures 4, 5, 6, 7, 8, 9, 11, including a second example embodiment, referenced 77, has been illustrated in FIG. 10.
- the console 76 shows, as best shown in Figure 9, the shape general of a rectangular parallelepiped defined by faces lower 78, upper 79, front 80 and side 71 of connection box 67, as to their respective orientation.
- the console 76 is pierced right through respective bore 82 whose internal section perpendicularly to the respective axis 56 is closely complementary of the outer section of a rod 64 perpendicular to this axis, so that, by each of these bores 82, the console 76 is slidably mounted on the two rods 64, in a direction parallel to the axis 56, that is to say vertical.
- This section can be cylindrical of revolution around the respective axis 56, as well as the interior section holes 57 and sleeves 58 and those of the bores blinds not referenced from the connection box 67, which interior sections are also closely complementary of the outer section of the rods 64, but it's fine understood that other sections, also closely complementary, could be chosen and that, in particular, the rods 64, externally, and the holes 57, bores 82, and unreferenced blind bores of the connection box 67, internally, could also have a section different, for example a fluted section allowing index the rods 64 around the axis 56 respective, especially to properly orient the holes crossing these rods 64 perpendicularly to the axis 56 to receive the respective pin 35 retaining with respect to the wall plate 1.
- the console 76 On each of its lateral faces 81, the console 76 carries jointly, projecting, a respective bearing 83 articulation around a respective axis 84 parallel to the axes 56 and located in a plane, not referenced, common to both axes 56, the two bearings 83 being mutually symmetrical compared to a plan confused with plan 21.
- the two bearings 83 are set back respectively towards the high relative to the underside 78 of the console 76 and downwardly relative to the upper face 79 thereof.
- the console 76 can receive different types of accessories, adapted to the shape of the frame 65 of the roof to be lifted and at the position of the device according to the invention 63 relative to the frame 65 thus conformed.
- FIG. 9 A first of these accessories, consisting of a bracket 85, is illustrated in FIG. 9 in two copies, each of which is carried by a respective bearing 83 and which are thus arranged respectively on either side of the console 76, while FIGS. 4, 5, 6, 11 illustrate a single copy of such a bracket 85 for such a console 76.
- Each bracket 85 has three straight arms 86, 87, 88 rigid and forming a rigid assembly, the first is parallel to axis 84 and runs along it, the second is perpendicular to this axis 84 and cantilevered relative to this one from one end by which this arm 87 is connected to the upper end of the arm 86, and the third of which obliquely connects the end free from the second arm 87 at the lower end of the first arm 86 to constitute a strut between the two arms 86 and 87, reference being made to a position of assembly of the bracket 85 to the console 76.
- the arm 86 carries in solidarity, opposite the overhang formed by the arm 87, a yoke 89 comprising two arms projecting perpendicularly at axis 84 and intersecting therefrom, at the rate of a lower arm 90 located under the corresponding bearing 83 and an upper arm 91 located above this bearing and extending arm 87.
- These two arms 90 and 91 are mutually spaced, along axis 84, of a dimension greater than that of the bearing 83 along this axis, and receive so integral but removable, along this axis 84, a common rod 92 of articulation of the square 85, around the axis 84, in this bearing 83.
- the rod 92 has a shape cylindrical outer of revolution around the axis 84, and the bearing 83 and the arms 90 and 91 are drilled along this axis a respective bore internally having the same section.
- the rod 92 is for example constituted by a screw having a head that we rest down on the upper arm 91 and a threaded end that receives a nut or assembly nut - lock nut under the lower arm 90.
- the upper arm 91 of the yoke 89 and the bearing 83 are positioned and dimensioned in such a way so that, if we let the set of square 85 rest down, by the upper arm 91, on the bearing 83, the arm 87 of square 85 is level with the face upper 79 of console 76, as an extension of this upper face 79, a flat upper face 93 perpendicular at axis 84, as shown in the left half of the figure 9. So there remains a space between the bearing 83 and the lower arm 90 of the yoke 89. This makes it possible to place also square 85 in a higher position by compared to console 76, as illustrated in the section on the right of this figure 9.
- Such an assembly also makes it possible to place the square 85 in a general orientation angularly offset, in particular by 90 °, around the axis 84 relative to the console 76, that is to say with respect to the common plane not referenced axes 56, in the case where the device according to invention 63 is placed near a nip point or protruding from wall 3, as also shown in half of right of Figure 9, it being understood that the settings of level of brackets 85 are mutually independent when two brackets are thus provided on the same console 76, of even that their settings are mutually independent orientation to it.
- brackets 85 are shaped so that they can be rigidly linked together, bracket 85 carried by a console 76 to a bracket 85 carried by a neighboring console 76, to constitute around the frame 65 a dynamic belt, that is to say offering a support as continuous as possible for structural elements 65 during lifting and after lifting, while raises walls 3 to the desired level.
- the arm 87 is constituted by a profile hollow, U-section open upwards, i.e. towards its face 93, in order to be able to receive internally a straight, rigid beam 94 for connection with the upper arm 87 from another bracket 85, corresponding to a console 76 neighbor, so that this beam 94 extends horizontally arm 87 and also provides support for elements of the frame 65, by an upper face 95 perpendicular to axis 84 and approximately coplanar with the face 93 of the arm 87.
- the beam 94 has been illustrated in FIGS. 5 and 6, in particular, in the form of an I-profile, one of the wings of which defines the upper face 95, but other modes of achievement could be chosen without going out for as much of the scope of the present invention.
- the beam 94 is retained so removable on the two arms 87 which it connects by means allowing limited vertical tilting, compatible with possible race deviations between consoles 76 or 77 during the raising of the roof; as an example no limitative, we can accept a tolerance of 3% in this regard over a meter of travel in the case of the use of cylinders, described later, for moving consoles 76 or 77 along the guide rods 64, this tolerance can be reduced to 0% by using electronic rules correction.
- the beam 94 is fitted inside U-shaped profile constituting each arm 87. It is there retained on the one hand by engagement of its extreme section, received inside the profile, under a horizontal pin 96 which runs along the upper face 93 of the arm 87 near the free end of it and goes right through profiled, perpendicular to it, in a position as there remains vis-à-vis the beam 94 a vertical clearance limited allowing the aforementioned limited vertical tilting as well as a sliding of the beam 94 inside the streamlined.
- each tie rod 98 preferably comprises means allowing a limited elastic variation of the distance mutually separating axis 129, fixed with respect to arm 87 corresponding, and the pin 97, fixed relative to beam 94.
- each tie rod such that 98 has the shape of a straight rod 210, of section constant and direction perpendicular to the axis 129.
- this rod 210 integrally carries a sleeve 133 coaxially engaged on pin 97 and retained so removable thereon, by any appropriate means and by example by pinning.
- the rod 210 is received and guided to slide, perpendicular to the axis 129, in a sleeve 130 itself articulated around axis 129 on arm 87.
- the rod 210 On both sides other of the sleeve 130, respectively, the rod 210 carries a adjustable fixed stop 131, 132, for example produced under the shape of a split ring fixed by tightening on the rod 120, the mutual spacing of the two stops 131, 132 in the direction of the length of the rod 210 being greater than the dimension corresponding of the sleeve 130 to authorize said variation, and a helical spring 134, coaxial with the rod, is maintained in compressive stress between the sleeve 130 and one of the stops, for example the stop 132 located opposite sleeve 133 for connecting each beam 94 to the two arms 87 who wear it.
- brackets 85 in one or two copies, together with a console 76 and with beams 94 connecting between the respective arms 87 of these brackets 85 are particularly suitable when the frame 65 of the roof to be lifted has elements distributed along a horizontal line, as it can be the case for example along a sand break, at the bottom of slope of a roof with two or four slopes.
- the connecting device 99 can be mounted on the bearing 83 of console 76 in a manner identical to that of bracket 85, via a base 100 provided for this effect of a yoke 114 in every way comparable to yoke 89.
- This base 100 defines an articulation bearing, around an axis 101 perpendicular to the two axes 56, that is to say horizontal, for a cradle 102 for receiving a rigid beam 103, straight and perpendicular in direction to axis 101, which we have along the crossbowman of so as to be supported either under it or under the frame 65 failures, if any through of suitable shims, and that one rests on at least two cradles 102, corresponding to two devices according to the invention 63 distributed over the pinion.
- Beam 103 is by example consisting of an I-shaped metal profile, one of which wing, for example the upper wing, is received and guided to the sliding in its direction perpendicular to the axis 101 in a zone that is complementary to the cradle 102.
- the beam 103 is part of a farm 136, preferably adjustable of which it constitutes a crossbowman and that we just brought under the frame 65 along the pinion, removably, to ensure continuity, at this level, of the dynamic belt otherwise formed by brackets 85 and beams 94.
- Such an adjustable truss can also be provided along cross walls, preferably in two copies arranged respectively on the part and other side of each cross wall, to ensure at this level the same load recovery functions, during lifting, and dynamic belt continuity link.
- such a farm 136 advantageously consists of an assembly of straight metal profiles, with two rafters such as 103 hinged together, and each connected by a device 99 to the console 76 of at least one device according to the respective invention and at least one entry 135, of preferably telescopic, articulated on these two rafters to allow an adaptation of the geometry of the farm to that of frame 65 and ensure support from each breakdown on the adjustable truss, if necessary via suitable wedging devices;
- the different articulation axes, such as 137, defined for example by yokes such as 138 are mutually parallel and perpendicular to an average plane, not referenced, of the farm 136, which is oriented substantially parallel to the wall gable or associated cross wall; crossbowmen such that 103 can themselves be telescopic, or be cut to length on site but you can also plan to allow a length to protrude from the roof larger or smaller depending on the dimensions of the roof, the where appropriate by savings arranged for
- each cradle 102 allows to adapt to each installation conditions, and in particular to orient if necessary the axis 101 perpendicular to the non-referenced plane of the axes 56, as illustrated in the right half of Figures 4 and 7, in the case of a device according to the invention 63 placed on a gable wall or on a cross wall, for example near the ridge failure.
- This device is designed to position itself on either of the bearings 83 of the console 76, in a way identical to device 99, and for this purpose has a flat base 140, vertical in use position, fitted a screed not visible in Figure 13 but at all points comparable with clevis 114 or clevis 89, to ensure the mounting of the device 139 on the corresponding bearing 83 of the console 76.
- the device 139 as a whole has symmetry with respect to an unreferenced vertical plane which also constitutes a plane of symmetry for the screed ensuring its mounting on the bearing 83 of the console 76 and includes axis 84 of this bearing 83 as well as axis 53, after mounting the device 139 on the console 76, so that the same device 139 can be used indifferently to right and left of a console 76, if one faces such a console.
- the base 140 of the device 139 has the form general of a rectangular frame, comprising two uprights vertical 141, mutually symmetrical about the plane of aforementioned symmetry of this device, and two crosspieces horizontal 142, respectively upper and lower, rigidly connecting the two uprights 141 respectively to their upper part and their lower part, perpendicularly to this plane of symmetry.

- Such a device 63 can advantageously be used to act on the two beams 103, forming a crossbowman, of the adjustable truss 136, at their articulation mutual, as well as under the blackout, as we have illustrated in figure 4.
- a device according to the invention 63 is located immediately below the rim, so that its axis 53 is secant from the ridge failure and, as much as possible, that the plane of symmetry 21 of the wall plate 1 and retaining plate 42 coincides with a vertical median plane of symmetry thereof, like the shows figure 14.

- the connecting device 163 comprises a rigid sleeve 165 engaged on beam 103, by sliding along it, and comprising for this purpose two flat side walls, vertical, mutually parallel 166, arranged respectively on either side of the beam 103 and forming the yoke 138 below it, a wall planar top 167 integrally connecting the two walls side 166 and resting on the upper wing of the beam 103, and a lower wall 168 running along the lower wing, so that the walls 166, 167, 168 define between they a channel 169 in which the beam 103 is guided at sliding lengthwise, without other play than a functional game allowing this sliding.
- each of the upper 167 and lower 168 walls and the corresponding wing of the beam 103 are interposed, at inside channel 169, two respective pads such as 170, 171 than a respective clamping screw such as 172, crossing respectively the upper wall 167 or the wall lower 168 and cooperating by screwing with this wall respectively higher or lower, allows, at will, either to tighten on the corresponding wing of the beam 103, to completely immobilize it inside the canal 169, relative to the sleeve 165, in any position 5 relative desired, either to loosen to release the beam 103 and the sleeve 165 with respect to a relative sliding in the direction of the length of the beam 103.
- the two side walls 166 define the axis 137 by a shaft 173 connecting them mutually, in solidarity, according to this axis 137 and bearing, with possibility of rotation around this axis 137, a rectilinear arm 174, radial with reference to axis 137.
- the arm 174 In a non-referenced mean plane, perpendicular at this axis 137, the arm 174 has a continuous slit 5 175 which subdivides it into two mutually symmetrical legs 176 relative to this plane and each of which is radial in reference to axis 137, as shown in figure 17 where we finds arm 174 identically.
- Slot 175 and legs 176 are sized so that the soul of the profile constituting the entry 135 also engages precisely as possible in the slot 175, between the legs 176, and that the latter, thus arranged respectively on the one hand and other of this soul, apply at best, flat, against the upper wing and the lower wing of the profile.
- This orientation can be freely chosen, depending on the slope of the roof to be lifted, by pivoting the integral assembly formed by the entry 135 and the arm 176 around the axis 137 relative to the sleeve 165 itself secured to the beam 103, it being understood that entry 135 is in principle horizontal whatever the inclination of the beam 103, adapted to that of the roof, relative to the horizontal.
- a separate device 178 of blocking which comprises a lower slide 179 slidably mounted along entry 135, by the wing upper of it, an upper slide 180, mounted at sliding along the beam 103, by the lower wing thereof, and a straight strut 181 connecting mutually these two slides 179, 180 and articulated on each of them around a respective axis 182, 183 parallel to axis 137.
- This device 178 arranged inside of the acute angle formed by the entry 135 and the beam 103 with reference to axis 137, can be immobilized by friction of parts 179 and 180 on the profile wing respectively associated, namely the entry 135 and the beam 103, or again by pinching effect applied at each part 179, 180 to the wing respectively associated, for example thanks to skids controlled by screws, similar in all respects on pads 170, 171.
- the strut 181 may have a length constant, in which case setting the relative orientation of the entry 135 of the beam 103 by rotation about the axis 137 is accompanied by a sliding of parts 179 and 180 on the associated wing respectively.
- the strut 181 has an adjustable length between axes 182 and 183, and is for example produced in the form a screw jack, in which case parts 179 and 180 are immobilized respectively on entry 135 and on beam 103 during the relative orientation adjustment of these last around axis 137, and this adjustment is made by adjustment of the length of the strut 181.
- the realization of these different variants of the device 178 falls normal skills of a skilled person and will not be detailed further.
- the upper wall 167 of the scabbard 165 carries securely, in an extreme zone higher if we take into account the joint slope of this wall 167 and the beam 103, assumed to be in position under the frame 65 to be raised, a screed 184 receiving and guiding, to rotation about an axis 186 parallel to the axis 137, a coaxial shaft 185 carrying itself in an integral manner, upwards, a bracket 187 intended to serve as a support to the intermediate breakdown on the one hand vertically downwards, and on the other hand in a horizontal direction in which the slope of the roof as well as the beam 103 is descending.
- the bracket 187 has a flat wing 188, showing a free edge at the top of the slope near which it is secured, downwards, with tree 185, and down the slope a bearing edge jointly another wing 189 perpendicular to wing 188 and parallel to axis 186, rising from its connection with wing 188.
- wing 188 can be placed horizontally and wing 189 vertically, to rest flat against the intermediate failure assumed to be vertical, or to present an orientation suitable to be applied flat against a breakdown having a different orientation compared to the horizontal, and for example an orientation perpendicular to the beam 103, means for adjusting the angle are provided 187 in orientation, around axis 186, in relation to scabbard 165, which will now be described.
- These means comprise, on the upper wall 167 sheath 165, two rectilinear rods 190 radial in reference to axis 186 and parallel to wall 167, that is to say to the general direction of channel 169 and the beam 103.
- Each of these rods 190 presents, taking into account the slope it presents as well, an upper end facing up the slope and secured to the wall 167 by means of a respective stop 191 that this wall 167 carries securely in the immediate vicinity of its lower edge, that is to say its edge facing the bottom of the slope.
- each of these rods 190 is slidably mounted, with possibility of immobilization in any position set desired along the rods 190, for example via a respective clamping sleeve 192 on the rod 190, a respective eyelet 193 of a hoof 194 thus guided to the sliding relative to the wall 167 of the sleeve 165, the along the rods 190.
- this guide of the shoe 194 can be supplemented by the engagement of a lug thereof in a fitted groove, parallel to the rods 190, in the upper wall 167 of the scabbard 165.
- the shoe 194 is thus disposed between the bracket 187 and the stops 191, that is to say shifted down the slope relative to the square 187, and present towards this last, that is to say towards the top of the slope, a 195 pan plane, parallel to axis 186 and inclined with respect to the wall 167 so as to form an angle with it upwards preferably greater than 90 ° and for example of the order of 135 °, this figure being indicated only as an example not limiting.
- the pan 195 is hollowed out of a groove 197 in which engages a lug 196 that the bracket 187 carries jointly, down the slope, at the junction between its two wings 188 and 189.
- the throat 197 Respectively on both sides of the throat 197 is arranged in the shoe 194 a light 198 parallel to the pan 195 and in which a lug engages respective 199 of post 196, so that post 196 either guided along the light 198 and either likely to turn further on itself inside this light 198; for this purpose, the two pins 199 have advantageously a cylindrical shape of revolution around the same axis 200 parallel to the axis 186.
- Figure 17 shows a device 164 having great analogies with the device 163, as noted above, in the measure where we find identical and under the same numerical references all of the elements described in reference to FIG. 16, with the exception of device 178, then absent, and of an embodiment different from the articulation of the arm 174 around the axis 137 relative to the yoke 138 defined by the side walls 166 of the sheath 165.
- the shaft 173 with axis 137 is integral with the arm 174 being guided in rotation about axis 137 relative to to the side walls 166 of the sheath 165, and bears integrally, outside the yoke 138 defined by these walls side 166, a coaxial pinion 201, in permanent engagement with a worm screw 202 that the corresponding side wall 166 door, to rotation about a parallel axis 203 to this wall 166, by means of a yoke 204.
- the worm 202 is connected by a universal joint 205 to a shaft 206 which itself carries a handwheel 207, which allows you to rotate will, one way or the other, the worm 202 around its axis 203 relative to the yoke 204.
- this rotation in one direction or the other, is accompanied by a pivoting of the arm 174, and with it the entry 135, around the axis 137 relative to the sheath 165 and to beam 103, in the direction of opening or closing of the angle formed between them by beam 103 and the entry 135, which allows to adjust the slope of the beam 103 with respect to the horizontal while preserving the horizontality of entry 135, in order to adapt the slope of beam 103 to that of the roof.
- the irreversibility of its assured transmission by the mutual meshing of the pinion 201 and the worm 202 ensures immobilization of entry 135 and beam 103 in the relative orientation thus adjusted.
- the beams 103 forming rafters and the 135 ties could be made in other forms, and for example be made up of tubes of circular section, the shape of cradles, channels, or other components or parts of components which cooperate with them being adapted accordingly, without difficulty, by a Man of job ; it could be the same for beams 94.
- brackets 85 and beams 94 could completely replace or partially to the brackets 85 and to the connecting beams 94 mutual to constitute the aforementioned dynamic belt either when the use of brackets 85 and beams 94 is made impossible by the conditions for setting up the device according to the invention, either due to a choice deliberate.
- console 77 rather than console 76 illustrated in figure 10, which is identical to the console 76 in particular as to the possibilities of receiving one or more two brackets 85 and a device 99 or 139, but is in further shaped to receive, in solidarity but removable, for example by fitting and pinning, on its upper surface 104 and / or its front face 105 turned to the opposite of wall 3, corresponding respectively to faces 79 and 80 of the console 76, specific accessories 106, 107 removable securing of a respective frame element, including a farmhouse or a crossbowman, respectively, having ends cantilevered by relation to the wall 3.
- the configuration of these accessories 106, 107 can vary to a large extent depending on the installation conditions and will not be further detailed, to the extent that it falls within the normal capabilities of a Tradesman.
- the upper face 79 of the console 76 could also be designed to receive the accessory 106 of receipt of a farm entry.
- Consoles 76 or 77 of devices 63 depending on the invention being equipped with the most suitable means for cooperate with the elements of the roof frame 65 to be lifted, namely brackets 85 and / or devices 99, 139, 148, 155 associated with adjustable trusses 130 and / or accessories 106, 107, and after fixing the wall plates 1 on wall 3, directly or through a respective gauge 115, while respecting horizontality axes 19 as good as possible then vertical adjustment axes 56 and connection between the guide rods 64 corresponding to the various devices 63 by tie rods 74, 75, on the one hand, and between the brackets 85 and the cradles 102, respectively, by beams 94, 103, while the consoles 76, 77 occupy a position as low as possible on guide rods 64, being naturally arranged above the yokes 29, a lifting is caused simultaneous, synchronized from the different consoles 76, 77 on the guide rods 64 by pushing means, advantageously constituted by hydraulic 108 or electromechanical jacks, associated with common
- Each device according to the invention 63 comprises thus a single jack 108, removably mounted on the retaining plate 42, by threaded holes 54 distributed around the notch 50 thereof.
- each jack 108 comprising a body 109 and a coaxial rod 110
- the body 109 is engaged in the coincident notches 50 and 22, respectively, the retaining plate 42 and the cradle 8 of the plate mural 1 and screwed, by a flange not illustrated, on the face upper 44 of the retaining plate 42 by the holes threaded 54 thereof, which ensures its positioning along axis 53, that is to say its perfect parallelism with respect to guide rods 64.
- Its rod 110 also thus arranged along the axis 53, is then placed in abutment upwards against console 76 or 77, from the underside such as 78 thereof to which this rod 110 is possibly fixed.
- this stroke is less than the lifting height, we can first lift, from the position of the roof in which the frame 65 of it rests on the walls 3, bring the roof 65 in an intermediate lifting position, in which immobilizes the consoles 76 or 77 on the rods 64, provisionally, by engagement of keys in respective holes, not shown, then placed in coincidence mutual. We then lower the rods 110 of the cylinders 108 to insert between each of them and the console corresponding 76 or 77 a shim having a height corresponding to the initial lifting height. Then, after having separated the consoles 76, 77 opposite sliding along the rods 64, the lifting by means of jacks 108, to the desired height, repeating this operation if necessary.
- a retention of the frame 65, downwards, in a succession of positions reached during lifting can also be obtained automatically, by cooperation of a snap device provided on each console 76, 77 with a rack parallel to the rods guide 64 and fixed relative thereto, and for example fitted directly along one of them, so not illustrated but easily conceivable by a Man of job.
- the invention can also be implemented by providing that the guide rods 64 slide coaxially in the sleeves 58 and carry the consoles together corresponding 76 or 77.
- the jacks 108 do not cause the consoles 76, 77 to slide on the guide rods 64, but an overall lifting of the brackets and guide rods, which slide in the sleeves 58 to provide the desired guidance.
- the pins 35 must be removed during the lifting operations, and put back in place, then that holes provided on the rods 64 coincide with the lights 34 of the screeds 29, whenever we want interrupt the lifting and in particular when raising the cylinders 108 and at the end of lifting, during the raising of the wall 3.
- a latching device mounted on the holding 42 and cooperating with a rack of the indicated type previously can also be provided for this purpose.
- Figures 18 to 21 show a wall 3 with its substantially vertical surface 112, which is here the exterior surface of the wall, it being understood that the lifting can also be fixed against an interior surface of this wall.
- a lifting device, noted 300, is fixed to the wall 3 by support means which are essentially constituted by two basic components, namely a wall plate 301 and an intermediate support plate 308. It is advisable to note that in some particular applications, by example industrial buildings with a steel frame, the lifting device will be fixed to a pole and not to a wall, this then requires an adaptation relating to aptitudes normal of a skilled person for mounting on pole.
- Wall plate 301 could be attached to the face 112 from wall 3 either directly by bolting or by through a template, as in the embodiment previously described. However, support has been provided here. direct from the wall plate 301 on a chain of the wall 3, that is to say on the upper face denoted 212 of this chain.
- the wall plate 301 has above a square 302 bearing on the face 212 of the chain of wall, the front face noted 303 of this square 302 presenting holes 304 used for the passage of fixing bolts 304.1 (shown only in Figure 21) anchored in the face 112 of the wall 3.
- the unitary horizontal part of the square can be replaced by two independent support shoes, whose position by ratio to the vertical part is adjustable, allowing a wall plate orientation adjustment by mounting support shoes on a respective perpendicular horizontal axis to this vertical part: this is in particular interesting when supported on an inclined chain.
- the wall plate 301 also has a pair vertical uprights 305 extending downward from square 302, and which have the particularity of forming a slide thanks to their U-shaped section whose opening is turned inward.
- a lower plate support In the lower part of each of vertical uprights 305 is provided a lower plate support, which may or may not be bolted to the wall 112.
- the intermediate support plate 308 is it essentially formed of a front plate 311 and of two horizontal crosspieces 312 and 313 whose ends pass inside the vertical uprights 305 for a vertical sliding guide for this intermediate plate support 308.
- a system of holes could be provided and pins associated with the vertical uprights to have successive heights for the intermediate plate 308 support.
- the wall plate 301 has a crossbar above horizontal 307 in the center of which hangs a rod threaded 309 thus extending in the vertical plane of symmetry of the slide formed by the uprights 305, up to a low level close to the lower support plates 306.
- the upper cross member 312 and lower cross member 313 of the intermediate support plate 308 then have a hole central allowing the passage of the threaded rod 309, and the support of the intermediate plate 308 at the desired height is ensured by a visible lower locking nut 310 only in Figures 18 and 19.
- the front plate 311 has two pairs of brackets 314 below which are fixed by a respective wing 315, the other wing 316 extending projecting substantially perpendicular to the plane of the front plate 311.
- the wings 316 each have a hole 317, the holes being all aligned on an axis common 19, which we will see later that this axis is no other that the axis around which the connecting retaining plate pivots the guide means and the controlled means of thrust with wall plate 301.
- the upper cross member 312 of the intermediate plate 308 also carries two small hollow sections 321 extending in a direction parallel to that of the slide formed by the vertical uprights 305, and arranged symmetrically with respect to the median plane of the intermediate support plate 308.
- Each hollow profile 321 has an oblong light on its front face opening 322 whose function will be explained below.
- attachment means 321, 322 on the back of a front plate 311 of greater height, between the horizontal crosspieces 312, 313 which are then more distant from each other: this reduces the overturning torque (thanks to lowering the fulcrum, and increasing the distance between the tear-off points in the slide), and also avoids having a through opening in the upper part profiles 321, which could be closed off with debris.
- the intermediate plate support 308 will be fitted with a clamping device adapted within the normal knowledge of Man loom, for example a self-clamping flange, the tightening torque increases with the load lifted (the load is then blocked in all directions thanks to upset corners and diamond-headed skates).
- the lifting device 300 further comprises a holding plate 342 supporting the guide means 64 of the console 76, the latter means being produced here under the shape of two parallel rods, on which can slide the lifting console 76 parallel to its plane which is brought into contact with the lower edge of the frame 65, edge which is represented schematically by a line in dashed lines in Figure 18.
- Rods 64 could be received below in sleeves integral with the tray holding 342 as is the case in the mode of realization previously described, but we have provided here a variant according to which each rod 64 has below a portion 323 of smaller diameter, allowing a direct support of each rod 64 on the upper face of the retaining plate 342, this portion opening out from the face lower of said retaining plate and allowing a locking for example by means of a wedge 324, as well as this is shown in figure 18.
- the holding plate 342 further presents here a central notch 352 associated with the passage of the body 109 of the lifting cylinder 108, the rod 110 of said cylinder being represented only by its upper end in FIG. 18, pressing against the underside of the lifting console 76.
- the console 76 may be formed of two sliding sleeves on the rods 64, joined by a housing connected below to the push cylinder rod and fitted a horizontal transverse axis on which a plate pivots adjustable tilt support: this is interesting for metal-framed industrial buildings, because the support plate can be linked directly, for example by bolting, to a horizontal or inclined beam of the frame. It will then be interesting to provide a plate additional guide at the top of the beam, cooperating with the vertical rods 64.
- the device lifting 300 also comprises means for adjusting the plumb, denoted 325, and level adjusting means, denoted 335, these adjustment means 325 and 335 connecting the support means constituted by the wall plate 301 and the intermediate plate support 308 to the common connection means formed by the retaining plate 342.
- the plumb adjustment was already provided in the mode previously described, in the form of a tilting around an axis by pressing on a cylindrical cradle.
- the means of adjustment plumb are arranged differently, which simplifies and considerably lighten the structure of the device.
- Plumb adjustment means 325 essentially comprise (in duplicate) a plumb adjustment element 326 and a plumb adjustment sheath 329.
- the setting element plumb 326 consists of a cylindrical head 327 and a threaded pin 328.
- the cylindrical head 327 is shaped to be received inside one of the two hollow profiles associated 321, so that the associated threaded axis 328 passes through the notched opening 322 extending projecting from the intermediate support plate 308.
- the adjustment sleeve plumb 329 has a threaded body 330 internally to screw onto the threaded pin 328, and a rear support flange 331 provided at the end of the sheath 329.
- the sheath 329 has a shaped end 332, for example under the shaped like a hexagon, this end thus forming a operation to be able to rotate the sheath 329 around of its axis.
- Intermediate plate 308 thus presents means 321 for fixing the plumb adjustment means 325, which are here constituted by the hollow sections 321.
- the fixing means 321 are arranged to allow a pivoting of the adjustment means 325 about an axis capable to be arranged horizontally and parallel to the surface 112 of the wall 3.
- the level adjustment means 335 comprise as for them, also according to a pair, elements 336 of level adjustment and level adjustment sleeves 339.
- a level adjustment element 336 is provided here comprising a head 337 of articulation 337 surmounted by a threaded axis 338.
- the articulation head 337 of each leveling element 336 is placed between a pair of brackets 314, and this head has an opening with axis 334 allowing the passage of a hinge pin 318.
- each pair of elements 336 and leveling sleeves 339 crosses the plate holding 342 while coming out at the level of the upper face of this one by oblong passage openings 343, these openings being arranged in a direction parallel to the pivot axis 19 defined by the hinge pins 318.
- each level adjustment sheath 339 has a body 340 internally threaded to screw onto the 338 threaded axis, a support flange 344 at the lower end, and, at the other end, for example a hexagonal operating head 341.
- FIGS. 18 to 20 also show, for the plumb adjustment means 325, a support washer 345 coming against the front face of the retaining plate 342 and held by a pin or circlip not shown associated with the adjustment sleeve 329, and, for the means 335 level adjustment, lower support shims 346 and upper 347, as well as a terminal support washer 348.
- the adjustment plumb is carried out by maneuvering the heads 332 of the sheaths plumb adjustment 329, which produces tilting desired around the axis 19 for the retaining plate 342, and therefore for the jack 108 or 108 ′ and the guide rods 64 supported by said holding plate.
- This plumb adjustment is shown diagrammatically by arrow 400 in FIG. will observe that, during a plumb adjustment, the lights oblong 333 do not interfere with the end of the adjusting means 325.
- the level adjustment is carried out in an analogous manner, by intervening on one and / or the other of the two heads of maneuver 341 coming out of the associated oblong openings 343, this intervention aimed at turning one or both sheaths 339 operated in such a way as to vary the level of the holding plate 342, as shown by the arrows 401 in FIG. 18.
- the intermediate support plate 308 has means 314, here in the form of brackets, for fixing the level adjusting means 335.
- these means of fixing 314 are arranged to allow pivoting of the level adjusting means 335 around the axis 19 which is can be arranged horizontally and parallel on the surface 112 of wall 3. It will also be noted that the 343 oblong passage openings allow travel angles of the retaining plate 342 during an adjustment level.
- the lifting device according to the invention can be used not only to raise the frame of an existing building, but also to lift the frame of a building under construction after installation in place of stabilized and braced straight posts.
- the device then makes it possible to maintain the frame at a intermediate stroke thanks to a clamping system within the normal knowledge of a skilled person: can then go up one level each time the means connection and thrust, consider a complete lifting of the frame from a low height (two meters from the ground for example) until its final positioning, which allows mounting of the frame at ground level where a significant time savings and a considerable decrease in risks for personnel operating on the construction site.
