Definitions

  • the invention relates to a hollow concrete floor or hollow concrete slab consisting of concrete with reinforcements and hollow bodies, wherein the hollow body between an upper and a lower armor layer at least partially substantially arranged in denseest possible packing, with areas between upper and lower armor layer can be provided without hollow body.
  • hollow bodies are known for the production of concrete ribbed ceilings.
  • the described hollow bodies are essentially quadrangular hollow bodies with an upwardly tapering cross section.
  • spacers the hollow bodies are placed on a lower shuttering and arranged in rows next to each other.
  • the distance between the hollow bodies is produced via subsequently introduced between the hollow body located in a row spacers.
  • hollow concrete ceilings or hollow concrete slabs can be produced, which have a directional support structure.
  • the invention has for its object to facilitate the construction hollow concrete ceilings and hollow concrete slabs.
  • substantially vertical reinforcements are provided, wherein the vertical reinforcements, at least in some of the interstices formed by three adjacent hollow bodies are arranged and as hinged reinforcements, preferably double-headed anchors are formed, and wherein the hollow body as open at the bottom, conical hollow body are formed with a substantially circular cross-section.
  • the hollow body concrete floor or hollow concrete floor panel thus produced has significant advantages. On the one hand can be dispensed with the reinforcement baskets. The distance between the upper and lower reinforcement layer is ensured by very inexpensive to produce upper and lower spacers.
  • the hollow concrete floor described requires no reinforcement of concrete ribs in the horizontal direction. This means that can be dispensed with the elaborate braiding of reinforcing rods. A weight and cost reduction results from the saving of unneeded concrete.
  • the weight savings is optimized by the arrangement of the hollow body in substantially closest possible packing.
  • the resulting tensile and shear stresses are absorbed by vertical reinforcements, which are mounted in some of each of three adjacent hollow bodies formed spaces.
  • the vertical reinforcements can simply be hooked into the spaces from above.
  • the described hollow concrete floor can have any basic shape. This is because the support structure is not addressed by the arrangement of the hollow body in dichtest possible pack.
  • the conical design allows stacking of the hollow body and thus a cost-effective transport and a cost-effective storage.
  • the hollow body can be made very thin-walled.
  • the spacers between upper reinforcement layer and hollow body on the one hand and lower reinforcement layer and hollow body on the other serve to be able to position the reinforcement layer exactly.
  • the reinforcement layer on the upper spacers also serves as a working plane, since it is walkable. It is of great advantage that the hollow bodies can be laid without contact contact measurement.
  • the hollow body and the upper and / or lower spacers form a unit.
  • the amount of work on the site is significantly reduced, since the upper and lower spacers do not need to be placed extra between the layers of reinforcement and the hollow body.
  • the upper and / or lower spacers can be made for example in a casting with the hollow bodies. The stackability of the conical hollow body is not affected.
  • the upper and / or lower spacers are annular.
  • the annular upper and / or lower spacer for example, ceiling or be attached to the bottom of the hollow body.
  • the upper and / or lower spacers of this shape are well adapted.
  • the annular design a better load of the hollow body is achieved.
  • the top wall of the hollow body is thus not subjected to bending.
  • a particularly advantageous development of the invention provides that the upper and / or lower spacers are composed of individual parts.
  • the fact that the spacers can be clipped into the hollow body can be varied by appropriate choice of the size of the spacer, the layer thickness of the concrete above and / or below the hollow body, without having to use hollow body with other dimensions.
  • the upper and / or lower spacers can be made separately from the hollow bodies. It can therefore be used as a hollow body commercially available containers.
  • the upper and / or lower spacers need only be attached to the containers on site. It is conceivable that the upper and / or lower spacers can be easily attached to the hollow body.
  • a particularly advantageous embodiment of the invention provides that the upper and / or lower spacers and / or the individual parts are fastened by means of an Anklipsmechanismus on the hollow body.
  • openings are provided at regular intervals on the circumference of the hollow body into which the lateral spacers can be clipped.
  • double head anchors are provided as vertical reinforcement. These are in at least some of the intermediate spaces formed by at least three adjacent hollow bodies mounted.
  • the double-headed anchors have proven themselves as vertical reinforcing bars. They serve to absorb the occurring tensile stresses and shear stresses. It is particularly advantageous if the attachment of the double-headed anchor takes place by means of a three-point bearing on in each case three adjoining hollow bodies.
  • hollow bodies having different average diameters are provided in the hollow concrete floor or in the hollow concrete slab. Smaller hollow bodies result in smaller spans. It can therefore be taken relatively high ceiling loads through the use of hollow bodies with a smaller diameter, without the concrete slab above and / or below the hollow body would have to be made thicker.
  • the hollow bodies are made of plastic.
  • the Hohl stressesbetonsupports is significantly reduced.
  • the production costs are very low, since the hollow plastic body can be mass-produced.
  • hollow bodies made of plastic it is on the one hand possible to use conventional concrete bucket as a hollow body to which the upper and / or lower spacers and / or lateral spacers are attached, and on the other hand hollow body made of plastic, in which the upper and / or lower and / or lateral spacers are formed directly.
  • lateral spacers are provided.
  • the lateral spacers make it possible to lay the hollow body without measuring it.
  • the distances between the hollow bodies can be adjusted as needed.
  • the hollow bodies with lateral spacers are transported from the truck to the lower reinforcement layers and then laid without measuring.
  • the spacers are assembled from individual parts. This means a space saving during storage and a relief during transport.
  • An embodiment of the invention provides that means for attaching the lateral spacers are provided on the hollow body.
  • the lateral spacers can be made separately from the hollow bodies, whereby commercial containers can be used as a hollow body.
  • the hollow bodies are attached to the hollow body on site at the construction site.
  • the attachment of the lateral spacers on the hollow bodies is facilitated by the fact that according to an advantageous embodiment of the invention, the lateral spacers are to be fastened by means of a Anklipsmechanismus on the hollow body.
  • the lateral spacers are introduced only in located on the circumference of the hollow body openings.
  • the lateral spacers are composed of individual parts. This brings advantages in storage, as storage space can be saved.
  • the lateral spacers and / or the upper and / or the lower spacers have openings distributed over the circumference. These serve for concrete passages.
  • the Openings guarantee a firm position of the hollow bodies in the hollow concrete floor, since the concrete fills the openings.
  • a development of the invention provides that at least some hollow body have at least two lateral openings for the inlet and outlet of gases and ate at least two openings of different hollow bodies are connected to each other via pipes.
  • the hollow body located after consolidation of the concrete in the Hohlköperbetondecke can be used as a heating or air conditioning system.
  • a fan for example, air through the cavities, which are interconnected by means of a pipe network, are transported. It is advantageously avoided to arrange complicated heating or air conditioning systems under the screed, etc.
  • At least some tubes have flaps. Through these flaps, the air flow can be controlled. This means that a selective control of the individual cavities with cold or warm air is possible.
  • FIG. 1 a buoyancy-free hollow body 1 is shown, the top wall 2 has vent holes 3.
  • upper spacers 8 are mounted on the ceiling side, the lower spacers 9 located on the lower side are in FIG. 1 not apparent.
  • the upper spacer 8 and lower spacers 9 are used for spacing the hollow body 1 of reinforcement layers, not shown.
  • On the hollow body lateral spacers 5 are attached.
  • the lateral spacers 5 are ring-shaped as in upper spacers 8. Around the entire circumference of the lateral spacers 5 and the upper and lower spacers 8,9 openings 6 are cut out.
  • the openings 6 of the upper spacers 8 lie in a concentric cylindrical surface 20.
  • the openings 6 of the lateral spacers 5 are located in a radial annular surface 21.
  • the openings 6 allow a concrete flow.
  • the integration of the hollow body 1 in the concrete through the openings 6 substantially improved, since the concrete penetrates the openings 6.
  • the hollow body 1 consists of a conical container made of plastic. This makes it possible to stack the hollow body 1 into one another.
  • FIG. 2 also a hollow body 1 is shown.
  • the lateral spacers 5 and the upper spacer 8 and the lower spacers 9 are angeklipbar to the hollow body 1.
  • the lateral spacer 7 is composed of four Parts together, which are to be clipped individually.
  • An assembly of the upper spacer 8 and the lower spacer 9 of parts is also conceivable.
  • the upper spacers 8 and the lower spacers 9 are plugged from above or from below onto the hollow body. In this embodiment, both spacers 8 and 9 are shown in one piece.
  • FIG. 3 the principle of a possible Anklipsmechanismus 11 is explained.
  • holes 10 are introduced.
  • the upper spacer 8 and the lower spacers 9 are inserted by means of a Anklipsmechanismus 11.
  • the Anklipsmechanismus 11 consists of a web 12, on whose, the lateral spacer 7 and the lower spacer 9 facing away from the end 13, an elastic wedge 14 is mounted, which rests upon insertion into the bore 10 to the web 12 and after introduction in the holes 10 upright again, whereby upper and lower spacers and the lateral spacers are fixed.
  • FIG. 4 a hollow body is shown in a hollow body composite. It is held by the lateral spacer 7 of the necessary distance to the adjacent hollow bodies. The hollow bodies are strung together in the densest possible package. The upper spacers 8 and the lower spacers 9 keep the distance to the upper reinforcement layer 15 and lower reinforcement layer 16. In known hollow concrete floors, the hollow body would have to be suspended in wire baskets. It is also new that the lateral spacers between the hollow bodies need not be subsequently introduced, which would prevent laying without gauging. The lateral spacers 7 and the spacers 8, 9, are attached to the hollow body 1 before installation or already form a unit with them. Only then is a great time savings when laying the hollow body possible. simultaneously is dispensed with a majority of concrete and steel, which reduces the weight and thickness of the ceiling.
  • FIG. 5 a double-headed anchor 17 is shown. This is hung in areas required tensile and shear reinforcement between adjacent hollow body.
  • the double-headed anchor 17 absorbs the tensile and shear forces, whereas the concrete absorbs the compressive forces.
  • FIG. 6 In FIG. 6 is shown a hollow body composite.
  • the hollow body 1 with lateral spacers 7 are joined together in the smallest possible density.
  • the hollow bodies 1 are located between two reinforcing layers, to which the distance is held by means of upper and lower spacers 8,9.
  • the upper reinforcement also serves as a work surface.
  • double head anchor 17 are suspended between adjacent hollow body 1. These are located in the spaces prescribed by the densest packing.
  • reinforcing baskets 19 are set up with the same dimensions as the hollow body 1.
  • the load capacity of the ceiling shown here is not directed. This means that ceilings with any layout can be built very easily. Previously, it was necessary to reinforce the individual ribs of hollow concrete slabs by means of horizontal reinforcements.
  • FIG. 7 shows hollow body 1 with lateral openings 22. These lateral openings 22 are connected to each other via pipes 23. Individual pipes have flaps on. It can now be pumped through the air connected by pipes hollow body in the finished ceiling. The ceiling thus also serves as air conditioning or heating. On a complex pipe system can be omitted.
