Definitions

  • the invention relates to a ceiling construction with a reinforced ceiling slab made of cast concrete, several reinforcing ribs made of cast concrete reinforced by lattice girders and filling elements arranged between the reinforcing ribs according to the preamble of claim 1.
  • a ceiling construction is known from AT-B-257 887.
  • the stiffening ribs are each reinforced by a prefabricated girder, which consists of a lattice girder and a concrete base, which can be embedded in a brick shoe.
  • Each filling element consists of a so-called cap stone and a view stone, both of which are suspended on the base of the precast element.
  • the main disadvantage of this ceiling construction is that the lattice girders used to reinforce the stiffening ribs, which must be designed in accordance with the structural requirements of the ceiling construction, have to bear the weight of the filling elements when the ceiling is being constructed on site.
  • the object of the invention is to provide a ceiling structure which avoids this disadvantage and simplifies the design of the ceiling structure on the construction site. This is achieved according to the invention in a ceiling construction of the type specified in the introduction by the features of claim 1.
  • the side parts of the skirting board or the side parts of the formwork sheet preferably run outwards and inwards Slightly sloping at the top, the side parts of the formwork sheet having slots for the wires of the lower grid mat.
  • the reinforcement of the ceiling slab is formed by the upper lattice mats of the filling elements and in the area of the stiffening ribs, butting reinforcements covering the lattice mats at their edges.
  • the ceiling construction according to the invention ensures that the filling elements as well as the lattice girders used to reinforce the stiffening ribs can be supported in such a way that the lattice girders themselves are not additionally loaded by the filling elements on the construction site.
  • EP-A-0 511 193 discloses a reinforcement body for a cast concrete ceiling slab provided with stiffening ribs.
  • the reinforcement body has a basic reinforcement, a distributor reinforcement as well as web wires connecting the base and distributor reinforcement and immovably fixing one or more displacement bodies.
  • the basic reinforcement, the distribution reinforcement and the displacement body (s) form a dimensionally stable unit.
  • either a plurality of rib cavities are formed in a one-piece displacement body to form the stiffening ribs, or a plurality of displacement bodies are arranged within the reinforcement body in such a way that a plurality of rib cavities are formed between the displacement bodies of the reinforcement body.
  • a disadvantage of the known reinforcement body is that the basic and distribution reinforcement extends over the entire reinforcement body, that is also over the areas of the rib cavities. This makes production more difficult and consumes more material than would be necessary.
  • the reinforcement body is accordingly also provided with a concrete element, which extends over the entire width of the reinforcement body and thus also extends over the rib cavities.
  • the ceiling plate formed with the reinforcement body has an upper and a lower element plate and a plurality of stiffening ribs connecting the two element plates.
  • a ceiling structure which has only an upper element plate and stiffening ribs
  • the reinforcement ribs widen slightly in the case of lattice girders cast in situ, ie lattice girders without a previously cast-on skirting board, due to the design and arrangement of the formwork sheets on the underside of the ceiling structure.
  • the formwork sheet which is intended to prevent the concrete from leaking when concreting the stiffening ribs, extends with a predetermined lateral overhang beneath adjacent filling elements.
  • a lower element plate which extends over the entire width of the ceiling, as in EP-A-0 511 193, is not provided according to the invention, but only a lower end of the stiffening ribs.
  • the load-bearing capacity of the ceiling according to the invention is ensured solely by the upper element plate.
  • the lower area of the filling elements remains free, which advantageously saves a considerable amount of concrete.
  • the invention also relates to a method for producing the described ceiling structure according to claims 1 to 3, which is characterized in that several supports are set up at predetermined intervals in accordance with the respective length and width of the filling elements, and mounting boards aligned with the stiffening ribs on the supports placed and arranged on the mounting boards at the edge of the stiffening ribs support boards for the filler elements, whereupon on the mounting boards either lattice girders provided with a concrete skirting board or formwork sheets for concreting the stiffening ribs are arranged in situ, the formwork sheets supporting the lattice girders and then on the supporting boards the filling elements are arranged, which are flush with the adjacent skirting boards, or the displacement body with its underside on the side overlapping the edges of the displacement body attack parts of the formwork sheets, and then pour the ceiling slab.
  • FR-A-896 890 relates to a structural element made of reinforced concrete for building a ceiling and a method for producing this ceiling.
  • the construction element consists essentially of supporting elements, a lattice work, a network stretched over the lattice work and reinforcing bars for reinforcing the ceiling slab.
  • the latticework consists of clamping elements and longitudinal reinforcement bars. To build the ceiling, the girders are placed on supports, then the latticework is applied, the net is stretched over the lattice, the reinforcing bars are attached to protrusions of the latticework and finally the in-situ concrete is poured.
  • the underside of the lattice can be closed with a metallic lattice.
  • the lattice girders are preferably supported on the formwork boards by means of spacers.
  • the ceiling structure shown in Fig. 1 has a ceiling plate 1 made of cast concrete, a plurality of stiffening ribs 2, which are arranged at a selectable distance from one another in accordance with the structural requirements of the ceiling structure, and a plurality of filling elements 3, which extend between the stiffening ribs 2.
  • a distributor reinforcement 4 is arranged in the ceiling slab 1, for example in the form of a grid mat, which consists of longitudinal wires 5 and transverse wires 6 which are arranged perpendicular to one another and welded to one another at the crossing points.
  • Each stiffening rib 2 is reinforced with a lattice girder 7.
  • the lattice girder 7 consists of an upper chord 8 and two lower chords 9, which are non-positively connected to the upper chord 8 by a zigzag infill 10.
  • the lattice girder 7 is reinforced by one or more additional reinforcements 11 in the area of the lower chords 9.
  • the lower chords 9 and the allowances 11 of the lattice girder 7 are concreted in a baseboard 12.
  • the reinforcement element of the stiffening ribs 2, consisting of the lattice girder 7, the allowances 11 and the concrete skirting 12, is already finished in the manufacturing plant and as complete unit delivered to the construction site.
  • the filling elements 3 have an upper lattice mat 13 and a lower lattice mat 14, which each consist of longitudinal wires 15 and 16 and transverse wires 17 and 18, which are arranged perpendicular to one another and welded to one another at the crossing points.
  • the upper and the lower grid mat 13 and 14 of the filling element 3 are connected to one another by a plurality of inclined web wires 19.
  • a displacement body 20 of a predetermined height is arranged in the middle, which expediently consists of foam, for example styrofoam.
  • the web wires 19 penetrate the displacement body 20 and, as shown in FIG. 4, are arranged such that the displacement body 20 is immovably and fixedly fixed between the upper and lower grid mat 13 and 14, respectively.
  • the web wires 19 can also run perpendicular to the upper and lower grid mat 13 or 14. In this case, it must be ensured by means of suitable fastening means that the displacement body 20 is also immovably and fixedly fixed between the upper and lower grid mat 13 and 14, respectively.
  • the filler element is constructed in the form of a three-dimensional, dimensionally stable lattice body, the filler element is self-supporting and is therefore able to bridge large spans without support during the construction of the ceiling structure at the construction site.
  • the reinforcement of the ceiling slab 1 is formed from the respective upper lattice mats 13 of the filler elements 3, wherein to cover the joints between the filler elements 3, an impact reinforcement 21 is placed overlapping on the upper lattice mats 13 of the filler elements 3 and connected to the wires of the grid mats, for example bridging.
  • both mesh mats and individual reinforcing bars can be used as impact reinforcement.
  • the upper grid mats 13th the filling elements 3 must be dimensioned and constructed so that they meet the static requirements of the ceiling slab to be produced.
  • the reinforcement of the stiffening ribs 2 is carried out by a lattice girder 7 ', which is constructed in accordance with the exemplary embodiment shown in FIG. 1 and is also provided with additional reinforcements 11 arranged in the region of the lower flange 9.
  • a lattice girder 7 ' which is constructed in accordance with the exemplary embodiment shown in FIG. 1 and is also provided with additional reinforcements 11 arranged in the region of the lower flange 9.
  • Different variants are shown in FIG. 2 for determining the position of the lattice girders 7 ′ including supplements 11 in the stiffening ribs 2.
  • the lattice girder 7 'together with allowances 11 is placed on a plurality of filling elements 3 common, lower lattice mat 14' bridging the gap in the area of the stiffening rib 2, and connected to it, for example bridged.
  • the common lower grid mat 14 ' consists of longitudinal wires 16' and transverse wires 18 'which are arranged perpen
  • the lattice girders 7 'in the exemplary embodiment according to FIG. 2 do not have a concrete skirting and therefore the concrete would flow out when concreting the ceiling slab 1 and the stiffening ribs 2, 2 temporary formwork sheets 22 are attached as the lower end of the stiffening ribs to be concreted.
  • the slightly sloping side parts 23 of the formwork sheets 22 (FIG. 3) are provided with slots 24 (FIG. 4) in order to be able to push the formwork sheets 22 between the cross bars 18, 18 'of the lower lattice mats 14, 14' in such a way that the Completely close the side parts 23 with the underside of the displacement body 20 and thereby prevent the concrete from flowing out when the reinforcing ribs 2 are concreted on.
  • the lattice girder 7 ′ including supplements 11 is arranged on a spacer 25, which in turn stands on the formwork sheet 22.
  • the construction of the ceiling structure at the construction site is carried out according to the schematic representation in FIGS. 5 and 6 in the following manner.

  • the lattice girders 7' are placed in the formwork sheets 22 in the following work step.
  • the distance between the lattice girders 7 'and the formwork sheet 22 is determined by the fact that either the lattice girders 7', optionally with the allowances 11, rest on the spacers 25 or on the lower, several filling elements 3 common lattice mat 14 '.
  • support boards 28 are placed as close as possible to the formwork sheets 22 or the baseboards 12 of the lattice girders 7, which have the task of carrying the filler elements 3 during the formation and when concreting the ceiling structure.
  • the displacers 20 of the filling elements 3 must be flush with the skirting boards 12 of the lattice girders 7 laterally to prevent the concrete from flowing out when the reinforcing ribs 2 are concreted.
  • the lattice girder 7, 7 ' is not burdened by the weight of the filling elements 3 when the ceiling structure is being constructed at the construction site, and can therefore be dimensioned correspondingly smaller.
  • the exemplary embodiments described can be modified in particular with regard to the type and design of the reinforcement elements for the ceiling slab and the stiffening ribs.
