Definitions

  • the invention relates to a boxlike structure, for example for use on a roof structure, having a number of vertical, substantially right-angled walls comprising a number of elongate louvre slats running parallel to one another, and a cover plate supported by these walls.
  • a known boxlike structure comprises a housing with walls consisting of metal louvre plates being profiled to receive mounting means of upstanding members of a rectangular frame.
  • Such a construction has the drawback that it has no flexibility with respect to dimensioning.
  • the invention has for its object to give a boxlike structure, for example for use on a roof structure, a form such that a great flexibility in dimensioning is achieved and that the boxlike structure can be assembled simply on site with the use of a minimal quantity of very simple tools.
  • the invention generally proposes a boxlike structure of the type described characterized in that each of both end zones of each louvre slat is fixed between two spacers, said spacers being arranged in two rows extending transversely to the longitudinal direction of the louvre slats being pressed towards one another by pressure means and being arranged to grip the louvre slats from two adjoining walls.
  • a louvre assembly is known, wherein the louvre slats are spaced apart by spacers whereas a connecting rod is used for clamping the slats and spacers inbetween channellike members of the frame. Also here no flexibility with respect to dimensioning is achieved due to the framelike structure.
  • the spacers can advantageously each take the form of a substantially block shaped member having at least one projection with two gripping surfaces positioned parallel to each other, at a preselected angle and at an interval from each other.
  • a very practical embodiment displays the special feature that the projection has the form of a block with a cross section in generally parallelogram form.
  • the form of the co-operating gripping surfaces is preferably complementary and adapted to the form of the louvre slats, being for example a profiled form.
  • the box-like structure according to the invention displays the feature that the spacers are provided with coaxial, continuous holes and that the pressure means comprise a member with tensile strength which can be placed through these holes, which member can be tensioned between the outermost end surfaces of the outer spacers of a row.
  • a very simple variant is one in which the member with tensile strength comprises a bolt or threaded rod having on one end a flange element and on the other a nut.
  • Each spacer is advantageously provided with a groove extending lengthwise of a row. Pairwise, these grooves can serve to accommodate for example a blind or perforated plate.
  • the blind plate can extend over a number of groove lengths, for example to form a blind wall
  • each spacer is provided with at least one hole extending lengthwise of the louvre slats for accommodating a plug, for example for attachment purposes.
  • the invention further relates to an end spacer consisting of a part of a spacer of the type already, described which is divided into two in a plane lying perpendicular to the longitudinal direction of a row.
  • the invention also provides a box-like structure comprising two end spacers, consisting of a part of a spacer as claimed in any of the claims 1-10 is divided into two, for example by sawing, in a plane lying perpendicular to the longitudinal direction of the row.
  • the invention also relates to a louvre slat for use together with a box-like structure of the type described, which louvre slat is characterized by at least one portion protruding outside the spacers, this portion being bent over such that it lies in the plane of the rows of spacers of the associated wall.
  • the protruding part can be perforated.
  • a roof elevation having a flanged edge to support a box-like roof structure.
  • the invention provides a roof elevation wherein the flanged edge extends outwards.
  • fig. 1 shows a box-like roof structure in perspective view
  • fig. 2 shows the roof structure as according to fig.1 in a view whereby the constituent parts are drawn at some distance from one another for the sake of clarity;
  • fig. 3 is a detail in which is shown the co-operation between spacers and louvre slats in a first embodiment
  • fig. 4 is a view corresponding with fig. 3 of a variant
  • fig. 5 shows the lower spacers of the column as in fig. 4, whereby the roof elevation with the base plate are also shown in partly broken away perspective view;
  • fig. 6 shows schematically a method for manufacturing end spacers
  • fig. 7 is a perspective view of a detail explaining the holes arranged in the projections.
  • Fig. 1 shows a box-like roof structure 1.
  • the same roof structure is shown in fig. 2 in a view in which the various constituent parts are shown at some distance from one another.
  • a roof 2 supports a roof elevation 3 with a square peripheral form, the upper edge of which displays a flanged edge 4 protruding outwards. As fig. 2 shows this flanged edge 4 is furnished with attachment holes 5 for passage of threaded rods 6.
  • the roof structure has four vertical walls 7, 8, three of which, namely the walls indicated with 7, are provided in the manner shown in fig. 2 with louvre slats 9 and the fourth of which, indicated by the reference numeral 8, has a blind plate 10.
  • the louvre slats 9 and the plate 10 form the roof structure 1 together with columns of identical spacers 11 each column having a bottom spacer 12 and an upper spacer 13 as will later be described.
  • the roof elevation 3 is first placed on the roof 2.
  • a base plate 14 is laid which is provided with holes 15, the position of which corresponds with the holes 5 in flanged edge 4 of roof elevation 3.
  • a threaded rod 6 is placed through the holes 5, 15 and at the bottom a nut 16 is screwed onto threaded rod 6.
  • a bottom spacer 12 is then first pushed over the four threaded rods 6, following which a bottom louvre slat 9 is placed on the associated spacers in a position to be described later.
  • a following set of four spacers 11 is then placed, after which one or more louvre slats are again placed, and so on, until finally upper spacers 13 are placed on the last louvre slats by sliding over the threaded rods 6.
  • the blind plate 10 is also coupled to the spacers 11 in a manner to be described later,
  • the position of the holes is, as will be apparent, in register with the position obtained for threaded rods 6.
  • Nuts 19 are arranged on the parts of the threaded rods 6 protruding above the fitted top plate 17, so that a tensile force results in the threaded rods 6 and thereby a pressure force is created between spacers 11, 12, 13, so that the louvred slats 9 are fixed rigidly.
  • Figure 3 shows a part of a column of spacers 11, with an upper spacer 13 shown at a distance.
  • Spacers 11 each take the form of a substantially block shaped element with two projections 20 having a form identical to each other, which are formed on adjoining side faces of the spacer 11.
  • Projections , 20 substantially take the form of a block having a cross section generally in the form of a parallelogram. With reference to fig. 3 the projection is now to be described;
  • the upper face 21 and the lower face 22 of projection 20 serve as gripping faces for louvre slats 9 that are to be fixed.
  • the lower face 22 of an element in a higher position co-operates with the upper face 21 of an element located beneath it to fix a louvred slat 9.
  • the angle at which the faces 21 and 22, which in this example are parallel, are placed can be selected as desired in relation to the determined purpose of use. It is also noted in this respect that the angles at which projections 20 are placed can differ from each other.
  • the louvre slats 9 show on both sides a part projecting outside the spacers 11, 12, 13 which is positioned at an angle with the main surface of the louvre slat 9 such that it is situated in the plane of the associated wall.
  • Figure 3 further shows that the spacers 11, 12, 13 are provided with holes 24 going through them which are in register for passage of a threaded rod 6, in the way shown in fig. 2.
  • FIG. 3 shows that the block shaped main bodies of spacers 11, 12, 13 are pressed onto one another with the surfaces that are facing each other, while as a result of the aforementioned (small) interval between gripping surfaces 21, 22 an excellent clearance free fixing of the louvre slats 9 is furthermore ensured.
  • Fig. 3 further shows that the projections 20, take a divided form, that is, it has in this case a vertically positioned groove 25 running through it.
  • vertical blind plates 26 can be fitted.
  • these blind plates 26 can have a greater height than that corresponding with the height of one spacer 11.
  • the rear wall 8 is not provided with louvred slats, but only with a blind plate 10 which is held in place in the grooves 25 of the respective spacers 11, 12, 13, these grooves being in line with one another.
  • the projection 20 displays two holes 27, 28 extending lengthwise of the louvred slats 9 for accommodating a plug, for example for attachment purposes.
  • Figure 4 corresponds with fig. 3.
  • This figure shows a variant indicated by 11' of the spacer 11 as according to the previously discussed figure.
  • the projections, indicated in this case by 20' are provided with active end surfaces, a top face 21' and a bottom face 22' respectively, having a complementary form, the shape of which is adapted to the profiled form of the louvre slats 9' shown in fig. 4.
  • Such louvre slats 9' have the advantage relative to the louvre slats 9 in accordance with the previously discussed figure that they are more rigid, which can be an advantage for longer louvre slats.
  • Figure 3 showed the way in which the top spacer 13 is placed on a spacer 11.
  • Figure 5 shows the way in which a bottom spacer, in this case designated by 12', co-operates with a spacer 11' placed above it in the embodiment as in fig. 4.
  • Figure 6 shows schematically a method for manufacturing two end spacers 12', 13'.
  • a spacer 11' is divided into two, for example by sawing, or by cutting using a laser beam, in a plane lying perpendicular to the longitudinal direction of a row, and therefore the longitudinal direction of the hole 24.
  • fig. 6 is the build up of the block shaped main body of, the spacer 11'.
  • This main body comprises four walls 30 standing at right angles to one another which in addition to being joined together with their vertical side edges are also joined together by a central transverse wall 31 which holds a hollow tube 32 passing through it, the interior of which, forms the continuous hole 24.
  • the plane 29 lies through the middle of the central transverse wall 31. This ensures that the mechanical strength and rigidity of the obtained end spacers 12' and 13' is as great as possible.
  • the build up of the projections 19' and 20' is also apparent from fig. 6. They are hollow, analogous to the form described of the block shaped main body of spacer 11' and the holes 27, 28 intended for the accommodation of, for example, a plug take the form of cylindrical elements.
  • roof structure 1 when a roof structure 1 is transported, all the parts can be grouped compactly, whereby the transport volume is comparatively small and the risk of damage during transport minimal.
  • the construction of roof structure 1 can be carried out virtually without special devices.
  • the roof elevation is placed, making use if desired of base plate 19, on the roof 2, threaded rods 6 are arranged, over which spacers 11, 12, 13 are placed, louvre slats 9 and if desired vertical plates, such as the plate 10, being positioned between them.
  • top plate or covering plate 17 is placed, after which the roof structure is completed using the nuts 19.
  • Adaptations required can be carried out simply at a later stage by additional placing or removal of spacers and louvre slats and/or plates.
  • Figure 7 shows a detail of an embodiment in which use is made in the right-hand wall of louvre slats 33 with perforated, bent over parts 23 which have a length such that, in the configuration of fig. 7, they connect together
  • Shown in fig. 7 also is a plug 38 which bears a threaded end 40 which can rotate as according to arrow 39.
  • the plug 38 is of the type which, by tightening of a nut 41 over a threaded rod 42, makes an internal plug 34 move in the direction of arrow 44, whereby the plug 38 that is manufactured of elastic material expands and becomes tightly fixed in a hole 27, 28.
  • This construction is for example suitable for arranging pivoting louvre slats which can be opened and closed. These are not shown in fig. 7.
