Definitions

  • the invention relates to a steel skeleton construction profile according to the preamble of claim 1.
  • the steel skeleton construction for which the new profile is intended uses lighter metal, in particular cold-formed sheet metal profiles, which carry the loads and support the spaces between the profiles.
  • the structure usually does not have its own supporting function.
  • the profile according to the invention is regularly intended for the removal of vertical loads and is therefore particularly suitable for the support of rising walls.
  • the invention relates to steel skeleton construction with large panels, which are manufactured as prefabricated parts and, above all, are assembled in building construction.
  • large panels form the rising walls and possibly the floor panes of the room cell.
  • the infills then generally consist of foam concrete.
  • space cells are still transportable as a whole, even with considerable dimensions.
  • large containers are suitable for large containers that serve different commercial and private purposes, especially residential purposes.
  • Such large containers are floor-to-ceiling structures in lengths of approx. 10 to 12 m.
  • Foam concretes for which the steel skeleton construction profile according to the invention is intended in particular, are concretes which correspond to the density and strength of the rigid foam lightweight concretes. They contain a substantial amount of aggregate, for example, polystyrene foam particles in the form of a blowing agent-containing styrene polymer, which belongs to the group of thermoplastics.
  • aggregate for example, polystyrene foam particles in the form of a blowing agent-containing styrene polymer, which belongs to the group of thermoplastics.
  • monostyrene is obtained as an intermediate via benzene and ethylene and mixed with a blowing agent and water.
  • the aggregate is obtained in round, glassy beads. If this material is softened by heating, the raw material particles expand, preferably using water vapor as a heat carrier and as an additional blowing agent.
  • the foamed beads that form the aggregate are spherical and have a cell structure in the form of a large number of closed chambers.
  • the bulk densities and the final strengths that depend on them are selected by the composition of the concrete so that they correspond to a structural concrete.
  • a typical composition of such a foam concrete used, for example, in the large panels according to the invention is as follows: 350 to 430 kg / cbm cement 20 to 70 kg / cbm of Rhine sand 800 to 500 l / cbm foam particles 140 to 170 l / cbm water.
  • the foam concrete used in the new large panels can receive reinforcement in the form of textile, alkaline fibers, preferably polypropylene staple fibers.
  • the steel skeleton construction profiles according to the invention together with the trusses described, form a frame in which the profiles form frame members which are connected at an angle-stiffness. This takes on the static function that the foam concrete cannot perform.
  • the new profiles preferably consist of folded sheet metal strips, which are expediently provided with rust protection, e.g. are galvanized.
  • the steel skeleton construction profiles according to the invention form frame stiffeners, which are usually arranged in pairs between the shorter outer frame members. Such frame stiffeners and possibly also the frame members should be light. That is why the new profiles consist in particular of folded sheet metal strips.
  • the ends of the profile sections cut to length lie in the profile chambers of the longer frame members, which generally have a corresponding cross section, so that the chambers are delimited by the profile legs and the profile webs on three sides and are open at least on one side inwards.
  • the stiffening profiles are fixed in the profile chambers of the frame members, for example welded.
  • Such panels are preferably produced in open formwork.
  • the finished frames are placed on spacers and the foam concrete is introduced from above with a layer that covers the profiles on their top side in the formwork with a comparatively thin layer of foam concrete, so that the frame profiles completely disappear into the hardened foam concrete.
  • This procedure places certain demands on the workability of the foam concrete, which ensures that the concrete fills the profile chambers, forms a smooth formwork surface on the spacer side and can be smoothed on the opposite side by pulling it off.
  • the frame construction described here and the subsequent production of large panels from these frames are not part of the previously published prior art (EPA 90 11 37 56.2).
  • the steel skeleton construction profiles which form the stiffeners of the frames generally consist of pairs of C-shaped profile sections which have a profile web provided with one or more beads to increase their dimensional stability.
  • the flanges of the C-profile are angled inwards and thus anchored in the concrete of the infills.
  • the profile section pairs are spot welded together with their webs lying against each other at the flange root.
  • These frame braces are also attached by spot welding to the edges of the frame members, namely on the outside of the profile flanges emerging from the profile chambers.
  • the invention has for its object to prevent the occurrence of cracks in the stiffeners, in particular at the locations described to facilitate the attachment of the stiffening profiles.
  • the invention simplifies the bracing by using angle profiles. These lie with the outer edges of the angle vertices in the depth of the concrete of the infills. They are anchored with the foam concrete in the infills through the recesses provided in the profile legs, which are traversed by the foam concrete during processing, as a result of which there are connections made of concrete that penetrate the profiles and end in adjacent infills. Since the outer edges of the angular apex lie and are fixed in the profile chambers, the profile legs run into the depth of the infills.
  • a wedge-shaped foam concrete filling is obtained which prevents the formation of cracks or counteracts the formation of cracks.
  • the resulting simplification of the profile shape has the advantage that the angle leg edges are accessible in the profile chambers and can be fixed there with welding beads or welding points.
  • the invention has the advantage that, in addition to reducing crack formation and improving the connection of the frame members with the stiffeners allows simplification of the profile production for the stiffeners.
  • additional anchoring of the stiffening profiles in the foam concrete infill can be obtained through the recesses.
  • This embodiment of the invention is the subject of claim 2. This avoids any sheet metal waste in the manufacture of the stiffening profiles because the cutouts required for the cutout remain on the profiles. They serve as anchors in the foam concrete infill.
  • an angle profile is also used as the basis for the new profile shape instead of the known C profile.
  • at least one of the angle legs is provided with a flange. This creates an open profile chamber, into which the concrete reliably penetrates and fills it.
  • an improvement in the stiffness of the angle profile is achieved, so that back-to-back welding of profile section pairs with the unpleasant consequence of cracks in the too thin concrete cover is eliminated.
  • the angle leg oriented parallel to the plane of the panel-shaped component can be used as a fastening means for a building board which is screwed to this flange, for example with a self-drilling screw, and consists of plasterboard or a mortar or concrete disc reinforced with a plastic net on one side.
  • This structure of the board means considerable progress in rationalization for the rising walls because it saves the plastering work in the finished building that would otherwise be necessary due to the natural roughness of the removed foam top inside the building.
  • the shape of this angle profile according to the invention is further optimized.
  • the realization of the features of claim 10 makes the profile chamber, which is completely closed on one side only, on the opposite side from the angle, a chamber which is further closed by the inward angle at the end of the profile flange. This leads to better anchoring in the concrete, which makes further anchoring measures appear superfluous.
  • the profile flange in question can be made longer because it is more dimensionally stable due to the angle leg. A longer profile flange alleviates the problem of fastening the building board, among other things, because it is easier to hit it with the screw and the joint arrangement of the building board cover.
  • the short flange is turned outwards, i.e. oriented downwards in the formwork of the profile element.
  • an angle can be provided which further closes the profile chamber and thereby reinforces the toothing with the infill.
  • the truss profiles are doubled in the trusses and welded back to back, thereby forming profile chambers on each truss side, which are filled with the concrete of the infills when the panels are manufactured lying down and the frame with be poured out of the lightweight concrete.
  • the crossbeams are angle profiles, which have recesses in both profile legs and must therefore be welded into the profile chambers, the apex line of the two angle legs runs approximately in the middle of the panel or the infills. This creates difficulties in production because the angle profiles have to be held in the formwork until they are fixed in the profile chambers by their welding.
  • the cutouts create strength problems which cannot be fully controlled by increasing the sheet thickness, but which lead to increased costs.
  • the invention also solves this specific problem in a simple manner, namely, inter alia. with the features of claim 15.
  • the arrangement of the cutouts in a center leg of the profile ensures that the building material bridge lie between the infills approximately in the central plane of the table, where they are most effective and that the profile flanges arranged in parallel planes are unprotected, which improves the strength. Since these profile flanges can be supported on the profile flanges of most U-shaped frame profiles when the truss ends are inserted into the profile chambers of the frame members, they are stably fixed for welding and can be spot-welded in them without difficulty.
  • the invention not only facilitates the processing of the truss profiles and improves their strength, it also ensures, through the use of the profile flanges on both sides, an improved dimensional stability of the trusses, which has a favorable effect on the safety of the truss profiles caused by the concrete bridges between the infills Buckling affects.
  • the crossbeams can be produced from thin metal strips, which are preferably galvanized and are therefore protected against corrosion. In the finished panel, the overlap of the profile flanges is sufficient to prevent cracking.
  • the steel skeleton construction profiles according to the invention are designed such that they are easy to manufacture. Since the recesses in the central axis of the profile are aligned, congruent and made at a uniform pitch, they can be punched out of the profile leg using simple tools. The irregular limitations of the punched holes produced recesses to additionally fix the profiles in the concrete bridges.
  • the invention is not limited to such simple profile shapes, but can be realized with profiles that have a relatively greater rigidity.
  • the basic profile provided for this purpose according to the invention is given in claim 19.
  • the profile leg is improved in shape by the formation of the divergent profile strips, without losing its flat shape, which is favorable for the recesses, which are in this embodiment in the center bar.
  • This basic profile is developed with the features of claim 20. This also improves the stiffness of the profile strips of the profile leg.
  • the profile flanges are additionally improved in their rigidity by the trapezoidal beads.
  • these beads also reduce the widths of those running parallel to the outer sides of the panels Sheet metal strips, which also counteracts the formation of cracks over the crossbeams.
  • This truss profile thus optimized can no longer be bent, but can be produced by rolling, which is the subject of claim 24.
  • the frame generally designated (1) is used to produce a large board (2) made of foam concrete, which is shown at (3) in Fig. 2.
  • the frame consists of profiled and mutually parallel longitudinal frame members (4, 5), which are connected to the shorter and also mutually parallel frame members (6 and 7) rigidly.
  • the longitudinal frame members (4 or 5) have a generally U-shaped profile with a flat web (8 or 9) and mutually parallel profile legs (10 or 11 and 12 or 13).

Recesses (46, 47) are located at regular intervals in the angle legs (FIG. 4). They serve to block the profile sections (38, 39) with the foam concrete of the infills (26-37), whereby the adjacent infills are each connected to one another by the cutouts (46 and 47). For the sake of clarity, the cutouts and cutouts in the drawings are much larger than those drawn in practice.
  • the stiffeners can be reinforced if the angle profile sections (38, 39) in pairs with mutually facing outer edges (48) of the angle apex (49) are created and welded to one another, so that an X-shape of the profile pairs (38, 39) results.
  • the ends (41, 42) are welded to one of their angle leg edges, as shown in the example of the angle leg edge (50) in FIG. 4, in the profile chambers (14).
