Definitions
- the invention relates to a device for stiffening large-area concrete elements in which hollow bodies are embedded for the purpose of concrete displacement. These concrete elements are mainly used for the production of floors and ceilings in concrete structures.
- the object of the invention is to provide a device for producing rigid concrete elements, in particular large concrete elements suitable for the formation of ceilings and floors, which allow the concrete elements or ceilings and floors to be produced quickly, easily and reliably.
- the handling is to be made easier, and the main aim is to move the manufacture of the device away from the actual installation location, so that the device can be created as a prefabricated intermediate or semi-finished product, can be stored temporarily and can be used appropriately on site if required.
- the invention provides as a solution that the hollow bodies arranged above or below the reinforcement grid are directly connected to the reinforcement grid by connecting members, so that they are secured against buoyancy.
- a reinforcement mat equipped in this way is then embedded in concrete.
- the hollow bodies are connected to the reinforcement mat embedded in the concrete, for example by attaching them, by means of clamping hooks, by means of a clamp or the like.
- a further reinforcement grid which is fastened via connecting rods either to the surface of the concrete shell, for example by gluing, or is partially cast into the concrete shell.
- the concrete shell has a thickness of 4-7 cm, in particular 5-6 cm, and can be used as lost formwork when creating floors or ceilings.
- the predominantly spherical hollow bodies can be provided with flattened sides.
- reinforcing ribs in various embodiments can also be provided on the hollow bodies.
- the hollow bodies can be assembled from hollow body halves by means of simple and stable snap connections or adhesive bonds in order to improve economy.

- FIG. 11 is a sectional view from the side of two adjacent hollow bodies with mutual connection
- FIG. 12 is a plan view of a connection of adjacent hollow bodies to a hollow body mat.
- Fig. 1 shows a semi-finished product for stiffening large-area concrete elements, which is formed from a flat concrete shell 1 with a reinforcement grid 2 of conventional construction embedded therein, that is to say from longer and transverse bars as well as hollow body elements 3 arranged thereon in a regular distribution, which here are represented as spheres.
- the balls 3 are arranged on the reinforcement grid 2, and in accordance with the exemplary embodiment shown they partially reach through the meshes of the grid 2 located between the grid bars. This arrangement, which takes place in a mold, is then formed by pouring concrete into the semi-finished product, so that the reinforcement grid 2 with the hollow bodies 3 is embedded in the concrete shell 1.
- the hollow bodies 3 are secured against buoyancy. This can expediently take place by direct connection of the hollow bodies 3 to the reinforcement grid 2, for example by clipping on or by connecting connecting members. In an alternative embodiment, however, the hollow bodies 3 can be held during the pouring by superimposing a surface structure, for example by arranging a holding grid above the hollow body elements 3.
- This semi-finished product which is manufactured in a factory, can then be transported to the construction site, stored there and then positioned by means of a crane of the building are implemented, the concrete shell 1 serving as a kind of lost formwork for the formation of the floor or the ceiling of the multi-storey building.
- struts are placed below to form a ceiling, which hold the concrete shell 1, whereupon concrete is then applied from above to form the ceiling until the hollow bodies 3 and, if appropriate, further reinforcement grids are embedded in total in the concrete ceiling.
- the semifinished product is supplemented to the extent that a further reinforcement grid 4 is placed on the hollow body elements 3 and fastened to the surface of the concrete shell 1 by connecting members 5.
- the connecting links are formed by rods, which are provided at the bottom with a rail or bar 6, via which the rods 5 are connected to the surface 7 of the concrete shell 1, for example by an adhesive bond.
- This prefabricated semifinished product according to FIG. 2 can also be delivered from the factory to the construction site, stored there and, if necessary, implemented by crane to create the structure, again the concrete shell 1 serving as lost formwork and concrete being applied to the hollow body elements 3 from above .
- the hollow body elements 3, the bars 5 and the additional reinforcement grid 4 are then completely embedded in the floor ceiling or the floor in the finished ceiling.
- the semi-finished product is formed by first arranging the reinforcement grid 2 in a form, then placing the hollow body elements 3 in mesh, finally placing a further reinforcement grid 4 and then the two reinforcement grid 4 by connecting links 5, which in turn are formed by rods, are connected to each other in a cage-like manner, so that the hollow body elements 3 are caught within the cage formed by the reinforcement grids 2 and 4. Then concrete is poured into the mold to form the concrete shell 1, in which the lower reinforcement grid 2 is entirely, the hollow body elements 3 as well as the connecting rods or connecting brackets 5 only partially and the upper one Reinforcement grid 4 is not embedded.
- This semi-finished product can then also be brought to the construction site and implemented by crane or manually.
- pockets, grooves or other recesses or projections and the like can be formed in the hollow body elements 3, so that there is a positive connection with the concrete of the concrete shell 1.
- Corresponding pockets are only shown by way of example in Fig. 1 on the left ball 3, here the pockets 8 are arranged selectively over the circumference, but alternatively can also be formed by a circumferential constriction or the like, as shown in Fig. 2 on the left with the Reference numeral 9 indicated.
- Fig. 4 shows an alternative embodiment in which the hollow body elements 3 are connected to a grid-like steel reinforcement.
- the hollow body elements then firmly connected to the reinforcement grid can then be embedded in the floor slab when it is formed.
- the hollow bodies 3 are placed on a perforated plate 27 which, according to the intended positions of the hollow bodies 3, has depressions 31 which are matched to the shape of the hollow bodies.
- the shaped plate 27, which has a multiplicity of depressions 31 in the desired arrangement, serves to determine the exact position of the hollow body 3 for the subsequent steps of forming a floor.
- a steel reinforcement 28, which is advantageously designed in the usual form as a grid, is placed on the hollow body 3 located in the shaped plate 27, so that the hollow body 3 can be connected to the steel reinforcement 28.
- the hollow bodies 3 can be fastened to the steel reinforcement 28 in a wide variety of ways.
- 3 connecting elements 32 can be provided on the hollow bodies, which are connected directly to the lattice bars of the steel reinforcement 28.
- clamping brackets 30, for example made of profiled steel wire is also conceivable.
- additional fixing rods 29, for example designed as plastic tubes can be used, which are fastened together with the hollow bodies 3 to the lattice bars 33 of the steel reinforcement 28 and thereby fix the position of the hollow body 3 to the steel reinforcement 28 .
- the semi-finished product is then installed in such a way that the concrete layer at the top, which contains the steel reinforcement and some of the hollow bodies attached to it, is turned downwards on supports, without the need for complete formwork, and then the missing upper part of the Floor ceiling is poured out at the construction site.
- the hollow bodies for example with the aid of the fixing rods 29 and the connecting elements 32 or clamping brackets 30, without steel reinforcement 28, so that only a lattice arrangement of the hollow bodies 3 is produced as a semi-finished product, which is then conventional Manufacturing technology of concrete floor slabs by means of formwork and pouring with concrete can be used.
- the steel reinforcement 28 of such a floor slab is then installed separately from the hollow body arrangement in the floor slab.
- FIG. 5 and 6 show two views of the hollow body arrangement on a lattice-like steel reinforcement 28.
- FIG. 5 shows a section of a plan view of the hollow bodies 3 located in the perforated plate 27, which are fastened to the steel reinforcement 28 placed thereon.
- a steel bracket 34 with barbs 35 is attached to the hollow body 3 so that the bracket 36 of the steel bracket 34 Lattice bar 33 of the steel reinforcement 28 comprises and the barbs 35 penetrate into the hollow body. Since the barbs 35 prevent the clip 34 from detaching from the hollow body 3, this provides a firm and secure connection.
- FIG. 6 shows the side view of a hollow body arrangement on a steel reinforcement 28, as can be installed in a concrete ceiling in the lower region of the floor ceiling when only one steel reinforcement is used.
- a second steel reinforcement can be attached to the top in a similar manner.
- FIGS. 7 to 10 show details of the connection of hollow bodies 1 to the steel reinforcement 28. While the alternative from brackets 34 with barbs 35 already described is shown in FIG. 9, FIGS. 7, 8 and 10 show a further embodiment of a connecting element 32.
- fastening elements 39 and 40 are provided on the hollow body 3, which are via a bracket 38 can be connected.
- the bracket 38 is pivotally articulated on the fastening element 40 at one end and is fastened at its other end, for example with a rivet 37, to the opposite fastening element 39.
- the fastening elements 39, 40 and the bracket 38 can preferably be formed in one piece with the hollow body 3 or a hollow body half.
- the hollow bodies are expediently constructed in each case from a plurality, in particular two, sub-elements and are produced, for example, by injection molding.
- the bracket which can, however, be made of any material, but is preferably elastic for better bracing, can of course be articulated in any other known manner.
- FIGS. 11 and 12 show how a connection between the hollow bodies 3 can be established by tabs 42 attached to the hollow bodies 3.
- the tabs 42 are articulated via a hinge element 44, which can be designed, for example, as a film hinge, to the hollow bodies 3, and preferably to a flange 12 of the hollow body 3, so that they can be folded in the direction of an adjacent hollow body.
- a hinge element 44 which can be designed, for example, as a film hinge, to the hollow bodies 3, and preferably to a flange 12 of the hollow body 3, so that they can be folded in the direction of an adjacent hollow body.
- locking openings 43 are correspondingly provided on the flange, into which the locking hooks 44 fastened to the tabs 42 can snap in order to achieve a firm connection between the hollow bodies 3.
- the latching hook 45 fastened to the tab 42 is preferably designed as a snap spring element in which the part forming the barb is designed to be elastically resilient in order to enable the connection to be loosened if necessary.
- latching elements in the manner of latching hooks which project outwards, or tangible tial or circumferential recesses can be provided in the manner of constrictions, which enable the hollow body elements to be clipped on or attached to the reinforcement grid for the purpose of connecting the hollow bodies.
- additional aids for the connection can be avoided, since the latching elements can be formed in one piece on the hollow body elements if necessary.
- the latching elements can also be formed separately on the hollow bodies, for example by providing hollow body openings into which the latching elements are pressed in a plug-like manner.
- a clamp-like design of the ends of the locking elements is also suitable for connecting the locking elements to the reinforcement grid.
