Definitions

  • the invention relates to a composite floor element for buildings constructed in modular design.
  • the individual modules of such buildings are created in steel skeleton construction and are characterized by high factory prefabrication.
  • the bottom elements of the known modules usually consist of a base frame of rolled U-profile with a plurality of spaced apart from each other in the frame cross members.
  • the floor frame of the known floor elements encloses a mineral insulation.
  • On the support of the frame a plywood planking and a possibly floating screed is applied.
  • the static proof of the carrying capacity of the known floor element is carried out exclusively on the dimensioning of the floor crossmember. For this reason, it is necessary to generously dimension the steel profiles of the floor frame and the cross member used in these.
  • the known floor elements are therefore relatively heavy and expensive.
  • the floor structure is often introduced only when the modules are assembled into a building. This is also expensive because it reduces the potential degree of prefabrication.
  • the invention is therefore an object of the invention to provide a floor element for building to be constructed in modular construction, which has a higher static load capacity than the previously known floor elements based on the weight.
  • the floor element according to the invention should be distinguished by the highest possible factory prefabrication degree.
  • a novel composite floor element for building constructed in modular construction comprising a frame and cross member made of metal profiles, preferably made of steel profiles, at least one DämmstoffIsoltechnik and at least one applied to the insulation layer of concrete, the insulation as a lost formwork is used for the concrete layer and where the profiles of the frame and the cross member partially from the concrete layer be recorded positively and form a supporting metal composite with the frame.
  • the frame and the cross member are formed as U-profiles.
  • the frame is composed of C-profiles, whereas the cross member are formed as U, double T, I or L profiles.
  • the cross member are designed statically as a single-frame carrier.
  • the upper leg of the profiles (upper straps) in installation position and / or partially the vertically extending sections of the profiles are embedded in the concrete.
  • the upper chords and / or the vertically extending portions of the double T, I- or L-profiles have a profiled surface.
  • top straps and / or the vertically extending profile sections of at least the cross member are provided with spaced holes, punched holes or embossments. If punched holes are provided in each case in the upper belts and / or in the vertically extending profile sections, these can be designed such that the punched-out material protrudes in the punching direction out of the relevant surface of the relevant leg of the profile.
  • the perforations and / or punched holes are penetrated by the concrete of the concrete layer, so that a positive anchoring of the relevant profile is ensured in the concrete.
  • insulation mineral wool can be provided.
  • the insulating layer is clamped over hook-shaped holding elements with the concrete layer.
  • the holding elements can be cast on one side in the concrete layer.
  • the concrete layer can be designed as a steel fiber concrete with dispersed steel needles.
  • a reinforcement in the form of steel mats or the like can be received by the concrete layer.
  • the cross members are formed as L-profiles with cutouts, folds or slots, the steel mats can be held for example by the vertically extending legs of the cross member.
  • the above-described variant of the floor element according to the invention makes use of the principle that the cross members are anchored in the concrete layer over at least part of their length (full dowelling).
  • the concrete layer has an edge-side enclosure, for example in the form of angle profiles. These angle profiles are conveniently welded to the frame profiles.
  • the compressive stresses are introduced into the concrete layer via the angular profiles provided at the edge. Additional measures for producing a positive connection between the cross members and the concrete layer are not required in this variant of the floor element (Endverdübelung).
  • the composite floor element (1) comprises a frame (2) and cross member (3) inserted therein, which can each be formed as U-profiles, the open side of the U-profile of the frame (2) facing inwards and the legs (4) of the frame (2) and the cross member (3) extend in the plane of the composite floor element (1).
  • the legs (4) serving as upper girths (5) of the profiles are embedded in a concrete layer denoted by (6) which has been applied to a mineral wool insulating layer (7) as permanent formwork.
  • the insulation layer (7) is additionally clamped by means of hook-shaped holding elements (8) on the concrete layer (6), wherein the holding elements (8) are also cast in one side in the concrete layer (6).
  • the upper straps (5) of the cross member (3) are each provided with spaced holes (9), which are penetrated by the concrete of the concrete layer (6).
  • the profiles of the cross member (3) of lesser strength than the profiles of the frame (2).
  • the profiles of the frame (2) are welded together in the corners; the cross members (3) are also welded into the frame (2).
  • the concrete layer (6) of the composite floor element is designed as a steel fiber concrete, i. in the concrete matrix steel needles (10) or the like are dispersedly distributed.
  • the concrete layer does not necessarily have to be made of steel fiber concrete. This can be provided without reinforcement or alternatively or additionally with a Baustahlarmtechnik.
  • FIG. 3 shows a further variant of the composite floor element (1) according to the invention.
  • the cross members (3) are designed as L-profiles (15), wherein the L-profiles (15) have a shorter leg (16) extending approximately horizontally in the installed position. and a longer, approximately vertically in the installed position extending portion (17) exhibit.
  • the vertically extending portion (17) of the L-profiles (15) is partially embedded in the concrete layer (6) and partially penetrated by the concrete layer (6), as will be explained below with reference to Figures 3a - 3g.
  • reinforcing steel meshes (11) can be embedded in the concrete layer (6) as an additional reinforcement.
  • the structural steel mats (11) rest on recesses, folds or the like of the vertically extending legs (17) of the L-profiles.
  • FIG. 3 a shows a perspective view of a variant of the cross member (3), in which the section (17) of the L profile to be partially embedded in the concrete layer (6) is provided with folds (18).
  • the folds (18) extend alternately in different directions.
  • the bends (18) extend only in one direction.
  • the variant of the cross member (3) shown in Figure 3c In the variant of the cross member (3) shown in Figure 3d whose vertically extending portion (17) is provided with slots (19).
  • the cross member (3) shown in Figure 3e is formed as a U-profile, wherein the upper flange (5) of the cross member (3) with a plurality of spaced-apart angle pieces (20) is provided.
  • a further variant of the crossbeam (3) is finally shown in FIG. 3f, where the leg (17) extending vertically in the installed position is provided with perforations (9).
  • FIG. 1 Another variant of the composite floor element according to the invention is shown in FIG.
  • the frame (2) is composed of C-profiles (12).
  • the cross members (3) are designed as lightweight double T-profiles (13). Additional measures for anchoring the cross member (3) in the concrete layer (6) are not provided in this embodiment of the composite floor element (1).
  • the concrete layer (6) is bordered by angle sections (14), which are welded on the top side to the C-profiles (12) and via which the force diversion and the bonding effect are achieved.
  • FIG. 3g shows a variant of the cross member 3 according to the invention, which is also designed essentially as an L profile whose vertical limbs are penetrated by the concrete layer both with bends (18) and with perforations (9).
  • This variant of the L-profile (15) has proven to be particularly favorable in terms of the composite effect to be achieved.
  • the combination of perforation (9) and fold (18) a permanent composite effect with the concrete layer (6) is achieved.
  • perforation From the perforation can be added to increase the composite effect, if necessary, a steel bar. By the steel bar an additional anchoring is achieved. It will be apparent to those skilled in the art that the perforation may be only partially penetrated by the bar steel, for example, every second or third perforation (9) of a cross member (3) may be penetrated by a steel bar. The dimensions of the perforation (9) on the one hand and the bar steel on the other hand can be chosen so that the perforation (9) is additionally penetrated by concrete.
  • the fold (18) absorbs forces acting perpendicular to the plane of the composite floor element (1) and thus reduces the edge pressure of the transverse beams (3), so that this contributes overall to the prevention of cracking in the concrete.
