Definitions

  • the invention relates to a prefabricated part made of concrete or other hardenable material, in particular a roof panel, with at least one plate which is provided with reinforcement and has webs projecting essentially perpendicularly from the plate, which stiffen the plate and a connection with a parallel to it allow running, essentially flat cover.
  • Such a prefabricated concrete part is known as a roof panel from DE-A-41 00 623.
  • the webs projecting upwards are formed by metallic lattice girders.
  • these lattice girders provide optimal stiffening of the roof panel, they have the disadvantage that they are susceptible to corrosion and have a high thermal conductivity.
  • the object of the present invention is therefore to improve the prefabricated part described at the outset, in particular in its use as a roof panel, in such a way that on the one hand no corrosion problems occur and on the other hand the thermal insulation is improved.
  • the finished part according to the invention should be inexpensive to manufacture and universally applicable.
  • the webs consist of fiber-reinforced plastic sheets which are inserted at one longitudinal edge into the plate made of concrete or other hardenable material and are anchored there in a form-fitting manner.
  • the invention is therefore based on the knowledge that the plate is no longer braced by metallic lattice girders, but by flat, fiber-reinforced plastic panels, so that there are no more corrosion problems and, at the same time, the previous thermal bridges are eliminated due to the low thermal conductivity of plastic.
  • fiber-reinforced plastic is considerably lighter than the steel previously used, so that the finished parts according to the invention are easier to transport and assemble.
  • Production takes place in such a way that the webs made of fiber-reinforced plastic are either placed on the reinforcement before the slab is concreted or the webs are pressed into the not yet hardened material of the slab. So you do not need a special casting mold as with roof panels with molded ribs, but you can use conventional flat-running formwork floors, which can also be easily changed in size.
  • the plastic sheets can form a hollow profile, so that the webs get a rectangular, triangular or trapezoidal profile.
  • This narrow section is connected with its narrow side, i.e. upright, to the concrete slab, so that there is a good stiffening effect.
  • the webs can also be formed by a corrugated sheet, the wave profile running parallel to the plate. This gives maximum load capacity with little material.
  • Openings can also be arranged in the area of the web above the plate if the statics permit this. In general, however, it is advisable to work with flat webs.
  • the longitudinal edge immersed in the plate can be glued into a U-shaped metallic fastening element, to which anchoring elements projecting in the transverse direction are then fastened, in particular welded on.
  • the plastic sheets need to be immersed in the plate only a few centimeters, a maximum of about 5 cm, preferably about 2.5 cm, so that the cutting effect of the webs on the plate is negligible.
  • the webs have a stiffening belt on their longitudinal edge facing away from the plate, which can also function as a carrier for connecting parts.
  • a stiffening belt is particularly recommended for webs that only consist of a thin layer of material, that is to say with the corrugated webs described, whereas a stiffening belt is automatically present in the case of hollow profile webs, namely through the narrow side of the hollow profile located at the top.
  • the stiffening belt expediently also consists of plastic, in particular fiber-reinforced plastic, and can be formed in one piece on the web or subsequently connected to it. It can already be equipped with protruding nails or the like, in order to subsequently accommodate fastening slats for a cover, in particular a roof skin. These fastening slats are expediently glued to the stiffening belt.
  • An advantageous development for the production of the finished part consists in the fact that the webs have support elements which are immersed in the plate. These support elements ensure that the webs in the formwork are stable before the concrete is poured. They also make sure that the one you want Immersion depth of the webs in the plate is not exceeded. This applies regardless of whether the support elements are placed on the reinforcement in the slab or on the bottom of the formwork. If, however, the webs on their base are wide enough, as is the case with the hollow profiles described at the beginning, they can usually be placed directly on the reinforcement of the slab.
  • the webs run in the slope direction of the roof, that the roof panels carry hinge parts on a longitudinal edge running transversely thereto, and that opposite roof panels are articulated to one another in pairs on the gable provided.
  • Such a hinge practically leads to a folding roof and considerably simplifies the assembly and alignment of the opposite roof panels, because the roof panels are transported in pairs and placed in exact assignment on the house walls or the ceiling tile.
  • the hinge together with the lower support points on both sides of the folding roof, forms a three-hinge frame that improves the stability of the roof.
  • an external metal reinforcement on the longitudinal edge mentioned, which encloses the edge of the roof panel, protects it from damage and at the same time stiffens the roof panels.
  • this reinforcement can carry a wedge which corresponds to the reinforcement of the opposite roof panel in the sense of a stop, that is to say limits the opening angle of the two roof panels.
  • Appropriate reinforcements are U or L profiles.
  • the roof panel also expediently carries a similar external reinforcement on the opposite longitudinal edge, which is used to support the roof panel on a ceiling plate or on a wall, an elastic intermediate layer, in particular made of elastomer, being arranged.
  • FIG. 1 you can see the section through a roof panel for pitched roofs.
  • This roof panel has a plate 1 made of hardenable material, which is usually concrete.
  • the underside of this panel is formwork smooth and can be painted or wallpapered condition directly the sloping wall of a loft, an attic or the like.
  • a reinforcement 2 runs in this plate 1, which is indicated by a dash-dotted line.
  • This reinforcement is, for example, a conventional structural steel mat or, in a comparable manner, reinforcing bars crossing at right angles, which are automatically inserted into the formwork provided for this purpose during the manufacture of the roof panel.
  • the inserted reinforcement is then concreted with hardenable material such as concrete during the manufacture of the roof panel.
  • FIG. 2 which shows the panel in the sectional view along the line II-II in FIG. 1, it has a corrugation that has an amplitude 5 of approximately 30 mm at a wavelength 4 of approximately 150 mm Has.
  • This corrugation stabilizes the web in the curable material of the plate 1 against buckling or buckling due to transverse forces.
  • an upper belt 6 is placed as a stiffening belt, that is to say either molded or glued on, which preferably has a glass fiber content of the order of 60 to 70% glass fiber. Its width corresponds approximately to twice the amplitude 5, so that the upper edge of the web is covered over the entire wave profile.
  • a spacer bar 7 or the like can be fixed, which in turn carries the roof battens 8, on which the actual roof covering is then attached in the form of bricks or the like.
  • the web 3 shown in FIG. 1 runs essentially along the sloping roof, while the roof battens 8 then run transversely to this, in a finished roof thus in a line parallel to the ridge or to the eaves of a roof.
  • the webs 3 can instead run transversely to the direction of the slope, in which case additional counter battens are usually required.
  • a sarking membrane can be provided, which is made of plastic and functions as moisture protection for insulation (not shown) which is placed on the plate 1 between the webs 3 in the form of insulating material.
  • the roofing membrane with the battens and the roof skin in the form of roof tiles or the like forms a cover which is connected to the plate 1 via the webs 3.
  • the web 3 which is made of glass fiber reinforced plastic, has only minimal thermal conductivity and thus does not form a cold bridge within the insulation formed by the insulating material lying against it laterally.
  • the plate 1 made of hardenable material has means for increasing the adhesion adjacent to its narrow side 9 which runs in the plate 1 and with which it is inserted in the concrete of the plate 1.
  • openings 10 penetrating the web are provided. These openings are penetrated by the concrete, which is the curable material of the plate 1, whereby a positive connection between the plate 1 and the web 3 is achieved.
  • the reinforcement 2 which is provided within the plate 1 also runs through these openings.
  • the dowel forces and the intimate connection of plate 1 and web 3 can be further increased by choosing the diameter of the openings 10 mm to be several times larger than the diameter of the reinforcing bars passing through them.
  • the openings 10 can be ⁇ -shaped, which means that the diameter 11 of the substantially circular or tropical openings 10 is larger than the gap 12 which is provided in the circumference 13 of the opening 10 to the lower edge 9 of the web 3 ,
  • This ⁇ -shaped shape favors the form fit mentioned.
  • Essential in the web shown here are also provided on the narrow side 9 of the plate 3, integrally molded upstand elements 14.
  • the web 3 is seated with a stand-up element 14 during manufacture of the component shown Formwork floor on which the plate 1 is cast from curable material.
  • the contact elements 14 thus form points on the underside 15 of the plate 1 which are hardly recognizable, while the underside is otherwise closed from hardenable material.
  • the reinforcement 2 can also be fixed within the openings 10, so that during the manufacture of the plate 1 the web 3 takes over the reinforcement of the reinforcement 2 on the corresponding formwork floor.
  • the web 3 can also be given a certain stable set-up due to a broader uprising base which corresponds to at least twice the amplitude 5.
  • FIGS. 3 and 4 also show two special features of the web according to the invention: On the one hand, a central opening 16 is provided, through which a line or the like can be passed through the web 3.
  • a central opening 16 is provided, through which a line or the like can be passed through the web 3.
  • openings can be used in the manufacture and transport of a roof panel according to the invention as a point of attack for a crane hook or the like.
  • FIGS. 3 and 4 recesses 17 on the upper side of the upper flange 6.
  • the counter battens 8 can be inserted directly into such recesses 17, with the spacing between two adjacent recesses 17 being used for hanging up the necessary distance between adjacent counter battens of roof tiles must be determined.
  • the web 3 can be guided laterally beyond the plate 1, the plate 1 then resting on a ceiling plate 18 or a house wall 19.
  • the section 20 of the web 3 protruding beyond the plate 1 can then be designed in accordance with a known rafter head and also act as a support for a gutter 21, which is then fastened to a separately provided eaves plank 23 via known gutter brackets 22.
  • FIGS. 6 and 7 show a further precast concrete element according to the invention, namely a double-walled hollow plate, which is shown in cross section in FIG. 7 and is produced using a web 24, as shown in FIG. 6.
  • This web 24, like the web 3, is provided at its lower end with recesses 10 or stand-up elements 14 with which it stands in a plate 25 and, as described above, also carries the reinforcement 26 provided therein.
  • the web 24 is mirror-symmetrical with respect to a central transverse plane 27, so that the web also has corresponding openings 29 on its upper narrow side 28, as well as corresponding contact elements 30.
  • a plate 25, which is produced as described above, is thus finished the curing and can then be placed with its web 24 in a prepared bed made of curable material, which then forms the further plate 31, which in turn is provided with a separate reinforcement 32.
  • a hollow chamber panel or a double-walled wall element is obtained, wherein either an insulating or insulating material can be filled into the cavity 33 between the two panels 25 and 31, or else a hardenable material, for example concrete. So that when it is filled with this insulating or hardenable material, it can pass through the webs 24, openings 34 are also provided in these, as can be seen in the figures.
  • the advantages of the components described here is in particular that the related webs 3 and 24 are not susceptible to corrosion due to their choice of material made of glass fiber reinforced plastic. Because of their corrugation, which can be seen in particular in FIG. 2, these webs are very stable and, via the support elements 14 and 30 provided on the web, no corrosion-sensitive elements emerge on the outside of the components produced according to the invention.
  • the web 24 can also take over the function of the spacer between two spaced reinforcements 26 and 32 and thus simplify the production while at the same time being cheaper due to the omission of separate stand-up or Allow spacer elements.
  • Figure 8 shows a roof panel similar to Figure 1. Therefore, the same reference numerals are used here for corresponding parts.
  • the anchoring of the web 3 in the plate 1 the web 3 here has a plurality of bores 10 in its area immersed in the plate 1, which are in a straight line in all the wave flanks in the longitudinal direction of the web 3 are arranged.
  • a single longitudinal rod 2 is sufficient to bring about the desired positive anchoring of the web 3 in the plate 1. It can be an existing reinforcement bar of plate 1 or an additional fastening bar.
  • the diameter of the bore 10 is again considerably larger than the diameter of the rod 2, so that the surface pressure on the circumference of the bore 10 is reduced accordingly, in the exemplary embodiment at least halved.
  • a top flange 6 running in the longitudinal direction of the web is attached to the top of the web 3. It can consist of the same material as the web 3 and can be glued to it. It expediently extends over the entire amplitude of the corrugated web.
  • Figure 9 shows another embodiment for the web.
  • a box web 40 is shown here. It consists of a substantially rectangular hollow profile made of fiber-reinforced plastic with a plurality of transverse walls and is open on its underside which plunges into the plate 1, so that the concrete inside the hollow profile reaches the same level as outside.
  • the box web 40 For the form-fitting anchoring of the box web 40, it has the openings 10 already described in its lower region which plunges into the plate 1 and which are traversed by an anchoring element 2, in particular a rod.
  • the web 40 carries an upper flange 6 which is thickened in wall thickness as an integral part which is integrally connected to it, so that no additional upper flange as in FIG. 8 has to be attached here. This is followed by the above-described crossbar 7.
  • FIG. 10 shows a web 41 in the form of a trapezoidal hollow profile which tapers upwards from the plate 1. Otherwise, the upper structure is practically the same as in FIG. 9.
  • the web 41 is at the lower end in U-shaped fastening elements 42.
  • These fasteners are made of structural steel and are glued flat to the longitudinal edges of the web 41.
  • the fastening elements 42 are welded to holding rods or reinforcement 2 on their underside.
  • the metallic fastening elements 42 may be expedient to pull the plate 1 slightly upwards in the connection area of the box webs.
  • FIG. 11 shows the connection of two roof panels 1 abutting one another in the gable area.
  • each roof panel carries a plurality of hinge parts 36 concreted in and connected to the reinforcement. These hinge parts protrude from the slabs 1 on a bevelled end face 1 a and each have a bore 36 a there.
  • the hinge parts 36 are concreted in such a grid dimension in the opposite roof panels 1 that the bores 36a of the successive hinge parts 36 come to lie one behind the other when the roof plates are aligned, so that a common hinge axis 37 can be inserted through all the openings 36a.
  • Both roof panels 1 are thus pivotally mounted on the hinge axis 37 and can be transported and set up together.
  • the hinge axis 37 expediently runs almost over the entire width of the roof panel and is available in the areas where no hinge parts 36 engage for hanging load hooks for transport.
  • hinge axis 37 can be used to anchor a ridge screed 43.
  • This ridge screed - generally made of wood - is placed on the hinge area from above and braced on the hinge shaft 37 by means of a hook screw 44 passing through the ridge screed.
  • FIG. 11 shows that the two roof panels each have an outer reinforcement 38 on their upper edge, which runs parallel to the gable.
  • This reinforcement surrounds the upper longitudinal edge of the plate 1 in a U-shape and, like the hinge parts, is made of stainless steel. It can have a stop, not shown in the drawing, in order to limit the maximum opening position of the two roof panels connected to one another.
  • the reinforcement 38 or the wedge, not shown, can alternatively or additionally be used for the assembly of the ridge screed 43.
  • Figure 12 shows the opposite lower edge of a roof panel, namely where it is supported on a building ceiling or building wall.
