Definitions

  • the invention relates to self-supporting building boards that can be used for free bridging rooms and openings and can be used for the construction of ceilings, walls, roofs, trusses, containers, bridges and for other construction purposes.
  • hollow panels which usually consist of reinforced concrete and have cavities inside. These hollow panels can be assembled without intermediate support, but must be transported to the construction site in a prefabricated state, which results in problems due to the high weight of such hollow panels during transport and assembly.
  • hollow panels can only be connected at their ends by pouring concrete, and these connection points result in "joint-like" weak points.
  • ribbed slabs are already known, which to a certain extent represent lost formwork that is poured with concrete at the construction site.
  • Such ribbed plates result in an advantageous unit when poured with concrete, but they require an intermediate support with an empty scaffold during assembly. The same applies to simple panels with cast-in lattice girders in the direction of wear, which are also poured out on site.
  • the underlying the invention task was to obtain self-supporting structural panels, which avoid the disadvantages of both Bauplattentypen described above and can be poured in place, but without requiring through an empty frame in the assembly of an intermediate support.
  • a disassembled self-supporting building board which is characterized in that it consists of a building material board and at least one building material strip connected to it via a lattice girder and at least one holding part, the lattice girder being arranged along the building material strip and on and against it the building material plate is fastened and wherein the holding part has a recess open on one side, through which the lattice girder runs, and is fastened to the building strip strip and the building material plate.
  • These dissolved self-supporting building boards according to the invention can surprisingly be assembled and poured out without intermediate support, they either being adapted to the size of the ceiling or as strip boards. As a rule, these building boards will have several strips of building material that run in the direction of wear. Formwork lost to produce hollow panels is inserted between the building material strips, resulting in the cavities.
  • the building boards according to the invention also have the advantage that they directly form a ceiling with the outer surface of the building material board, which can be cleaned, so that no additional suspended ceilings are required.
  • the building boards according to the invention immediately result in the final ceiling thickness when pouring.
  • the holding parts serve, at the same time as the spacing between the building material plate and the building material strips, to absorb additional thrust forces.
  • the bracket parts can also "additionally contain reinforcement to increase the load capacity.
  • the bracket parts can be shaped differently, but they must have a recess open on one side in order to insert the lattice girders. In the end position, the bracket parts must grip around the lattice girders.
  • the recesses in the holder parts can be designed differently, such as, for example, circularly with a lateral opening, but an expedient design of the holder part is that with an essentially U-shaped cross section.
  • the building material of the building board as well as the building material strip is usually made of reinforced concrete, so that the bracket parts are suitably made of concrete and preferably of concrete U-stones.
  • lattice girders can be used as lattice girders, and these have an essentially triangular cross-section with a rod arranged after installation along the concrete strip at the apex of the angle legs and two essentially parallel rods which form the free edges.
  • the rod at the top of the lattice girder can now be attached either to the building material panel or to a building material strip.
  • the lattice girder is preferably fastened to the building material strip with the rods lying at its two free edges and with the rod at its apex to the building material plate.
  • the lattice girder is attached to these parts in such a way that its free edges or apex are poured into the concrete together with the reinforcement of the building material plate or the building material strips .
  • connection of several such building boards at the end of the building material strips is carried out in the same way by pouring with concrete, whereby reinforcements can also be inserted here and / or the reinforcements of the building material plate and the building material strips can protrude at their ends and thus the connection between these ends and the poured-out one Create an area between two adjacent building boards.
  • reinforcements can also be inserted here and / or the reinforcements of the building material plate and the building material strips can protrude at their ends and thus the connection between these ends and the poured-out one Create an area between two adjacent building boards.
  • the building material strips are kept shorter than the building material board in the direction of wear.
  • the construction boards according to the invention can expediently be produced in the following manner.
  • the bracket parts are inserted so that they encompass the respective lattice girder. If it’s the stops tion parts expediently U-stones, they are inserted into the formwork for the strips of building material that they stand with the free legs in the formwork.
  • This formwork is then filled with the building material, usually concrete, and cured. Now the strips of building material with the reinforcement, lattice girders and mounting parts embedded in them are removed from the formwork and rotated by 180 °. Then the formwork for the building material panel i: of the desired size is made, and the desired number of building material strips is inserted into this formwork of the building material panel with the support parts and lattice girders pointing downwards. Finally, the building material, preferably concrete, of the building material plate is filled into this formwork and cured. After removal from the formwork, the building board according to the invention is then ready for use.
  • the building material usually concrete
  • spacers in the production of the building boards according to the invention during the filling and hardening of the building material material of the building material plate, which ends of the building material strips are at the desired distance hold of the building material slab to be cast.
  • An expedient embodiment of such a spacer consists of a vertical rod with a standing device at one end, a stop for the outer surface of the strip of building material at the other end and a toggle which can be displaced on the rod. This gag can be struck with a few strokes along the vertical rod up to the building material strip so that its free end is fixed between the stop and the gag.
  • a spacer is used, the gag of which consists of a part comprising the rod, the recess penetrated by the rod having two mutually substantially parallel inner walls, which are not perpendicular but at an angle to the upper contact surface of the gag for the end of the strip of building material.
  • the inner wall of the gag which lies on the side of the rod on which the end of the strip of building material rests on the gag, forms an obtuse angle with the contact surface of the gag.
  • the resolved self-supporting building board shown in the drawing according to the invention consists of a building material plate 5 with a reinforcement 4 and building material strips 1, each with reinforcement 2, with only two of these building material strips 1 are shown in Fig. 1 of the drawing. Furthermore, the building board consists of mounting parts 12 in the form of U-stones and lattice girders 3, with each building material strip 1 being assigned a lattice girder 3 and a plurality of mounting parts 12.
  • FIGS. 4 to 7 which show the production of the building board according to the invention, the lattice girder 3 is first inserted with its two free edges 18 downwards together with the reinforcement 2 into the formwork for the building material strip (FIG. 4).
  • the mounting parts 12, which in the drawing have trough designs 14, are placed with the open side downward at certain intervals from one another over the lattice girder 3 and placed in the formwork of the strip of building material 1 (FIG. 5).
  • FIG. 5 With a horizontal section through FIG. 5 along the line VI-VI, the image shown in FIG. 6 results, which shows that the U-stones are placed over the lattice girder 3 at their narrowest points.
  • the building material strip with the lattice girder embedded in the concrete and the mounting parts cast in concrete is rotated through 180 ° and placed on the reinforcement 4 in the formwork of the building material panel 5, as shown in FIG. 7.
  • the apex 19 of the lattice girder 3 is connected to the reinforcement 4 of the building material plate 5, as can best be seen from FIG. 8.
  • FIG. 9 shows how the self-supporting building boards according to the invention are placed on walls 16 via mortar connections 17 and connected to one another in the area of reference number 15. It is expedient that the building material strip 1, as shown in Fig. 9, is shorter than the building material plate 5 and that at the ends of the building material plate 5 and the building material strip 1, the reinforcement protrudes.
  • the spacer shown in FIGS. 2 and 3 is expediently used, which consists of a rod 6 with a stand device 8 and an upper stop 7 and a slidably mounted toggle 9.
  • This has a through opening through which the rod 6 passes, and the inside of this opening is at an angle ( ⁇ ) to the support surface for the end of the building material strip 1, with the inside of the recess, which is in the area of the end of the building material strip, with the support surface includes an obtuse angle ⁇ .
  • the opposite inside of the recess is parallel to this, so that under the pressure of the overlying end of the strip of building material the gag is wedged on the rod 6, but can easily be released again by one or more hammer blows on the outer upper end.
