Definitions

  • the invention relates to self-supporting building boards and their manufacture, which can be used to bridge bridges and openings freely and can be used for the construction of ceilings, walls, roofs, trusses, containers, bridges and for other construction purposes.
  • hollow panels are known, which are usually made 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 removal and assembly. In addition, such 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.
  • DE-A-1609571 already shows a disassembled self-supporting building board according to the preamble of claim 1.
  • the object on which the invention was based was now to obtain self-supporting building boards and to manufacture them, which avoid the disadvantages of the above-described building board types and are poured in place can, but without the need for intermediate support by an empty scaffold.
  • These disassembled self-supporting building boards according to the invention can surprisingly be assembled and poured out without intermediate support, whereby they can either be adapted to the size of the ceiling or as strip strips.
  • these building boards will have a plurality of second board parts designed as strips, which run in the direction of wear. Formwork lost to produce the hollow panels, which result in the cavities, is inserted between the second panel parts.
  • the building boards according to the invention also have the advantage that they directly form a ceiling with the outer surface of the first plate part, which can be cleaned, so that no additional suspended ceilings are required.
  • the building boards according to the invention immediately give the final ceiling thickness when pouring.
  • the holder parts serve simultaneously with the spacing between the first plate part and the second plate part to absorb additional thrust forces.
  • the bracket parts can also 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 mounting parts can be designed differently, for example circularly with a lateral opening, but a practical design of the mounting part is that with a substantially U-shaped cross section.
  • the building material of the first plate part (5) as well as the second plate part designed as a plate strip is usually made of reinforced concrete, so that the mounting parts suitably consist 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 first plate part or to a second plate part.
  • the lattice girder is preferably fastened to the second plate part with the rods lying at its two free edges and to the first plate part with the rod at its apex.
  • the lattice girder is attached to these parts in such a way that its free edges or apex are executed together with the reinforcement of the first slab part or as a slab strip second plate part are poured into their concrete.
  • connection of several such building panels at the end of the second panel parts is carried out in the same way by pouring concrete, wherein reinforcements can also be inserted here and / or the reinforcements of the first panel part and the second panel part can protrude at their ends and thus the connection between these ends and create the poured area between two adjacent building boards.
  • reinforcements can also be inserted here and / or the reinforcements of the first panel part and the second panel part can protrude at their ends and thus the connection between these ends and create the poured area between two adjacent building boards.
  • the second board part is kept shorter than the first board part in the direction of wear.
  • the construction boards according to the invention can expediently be produced in the following manner.
  • the formwork for the second slab part is produced in the required number, and the reinforcement of the second slab part and the lattice girder assigned to each second slab part with its two free edges, i. H. with its top up, inlaid.
  • the bracket parts are inserted so that they grip around the respective lattice girder perpendicular to the building board level. If it is expedient for the mounting parts to be U-stones, these are placed in the formwork for the second plate parts in such a way that they stand with the free legs in the formwork.
  • This formwork is then filled with the building material, usually concrete, and cured.
  • the second plate parts with the reinforcement, lattice girders and mounting parts concreted in are then removed from the formwork and rotated by 180 °.
  • the formwork for the first plate part is prepared in the desired size, and the desired number of second plate parts is inserted into this formwork of the first plate part with the support parts and lattice girders pointing downwards.
  • the building material, preferably concrete, of the first plate part is filled into this formwork and cured. After removal from the formwork, the building board according to the invention is then ready for use.
  • spacers in the production of the building boards according to the invention during the filling and hardening of the building material of the first plate part, which ends the second plate part in the Keep the desired distance from the first plate part 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 second plate part 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 second plate part 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 plate strip.
  • the inside wall of the toggle which lies on the side of the rod on which the end of the plate strip rests on the toggle, forms an obtuse angle with the contact surface of the toggle.
  • the resolved self-supporting building panel shown in the drawing according to the invention consists of a first panel part (5) with reinforcement (4) and a second panel part or panel strip (1) designed as a strip, each with reinforcement (2), wherein in 'Fig . 1 of the drawing, only two of these second plate parts (1) are shown.
  • the building board consists of mounting parts (12) in the form of U-stones and lattice girders (3), a lattice girder (3) and several mounting parts (12) being assigned to each plate strip (1).
  • Lost formwork (10-11) can be inserted into the self-supporting building board to form cavities.
  • FIGS. 4 to 7 which show the production of the building board according to the invention, first the lattice girder (3) with its two free edges (18) downwards together with the reinforcement (2) is inserted into the formwork for the second board part (1 ) inserted (Fig. 4). Then the holder parts (12), which have trough designs (14) in the drawing, are placed with the open side downwards at certain intervals from one another over the lattice girder (3) and placed in the formwork of the second plate part (1) (FIG. 5 ). 5 along the line VI-VI results in the image shown in Fig. 6, which shows that the U-stones are placed over the lattice girder (3) at their narrowest points.
  • the second slab part with the lattice girder concreted in and the concreted-in mounting parts is rotated by 180 ° and placed on the reinforcement 4 in the formwork of the first slab part (5), as is shown in Fig. 7.
  • the apex (19) of the lattice girder (3) is connected to the reinforcement (4) of the first plate part (5) with the help of an S- or Z-shaped bracket (13) with a curved web, as best seen in FIG. 8 is.
  • 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 the reference number (15). It is expedient that the second plate part (1) as shown in Fig. 9 is shorter than the first plate part (5) and that the reinforcements protrude at the ends of the first plate part (5) and the second plate part (1) .
  • the spacer shown in FIGS. 2 and 3 is expediently used, which consists of a rod (6) with a standing 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 inner sides of this opening are at an angle ( ⁇ ) to the bearing surface for the end of the second plate part (1), the inside of the recess being in the region of the end of the second plate part lies with the contact surface enclosing an obtuse angle alpha.
  • the opposite inside of the recess is parallel to this, so that under the pressure of the resting end of the second plate part 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.
  • This dissolved self-supporting building board can be used as a ceiling, wall or bridge board or also as a support, the first board part (5) being curved in cross-section or being bent one or more times.
  • the second plate part (1) is interrupted, as the top view in FIG. 11 shows.
