Definitions

  • the invention relates to a wall element of a structure, comprising two rigid, elongate, structural, supporting steel profiles, each having an internal cavity extending along a longitudinal axis of the steel profile and open at the profile ends, which are constant over the entire length
  • a wall element comprising two rigid, elongate, structural, supporting steel profiles, each having an internal cavity extending along a longitudinal axis of the steel profile and open at the profile ends, which are constant over the entire length
  • the cross section has eight rectangular outer corners and four rectangular inner corners, between two adjacent outer corners each have a support surface between an outer corner and an adjacent inner corner each having a mounting surface
  • the cross section has a rotational symmetry of 90 ° and each mounting surface a regularly arranged row of holes
  • a plate which is connected to the steel profiles and has the narrow surfaces.
  • Such a wall element is from the WO / BE2013 / 000030 known.
  • the plate is connected to support surfaces of the steel profiles, which lie in a common plane.
  • the invention relates to steel skeleton construction.
  • the structure of a building is built in skeleton construction with steel girders.
  • steel girders In the skeleton building walls and ceilings are inserted, which allow to close the open surfaces of the skeleton.
  • the invention is not aimed at larger buildings or even skyscrapers, as they are typically built in steel skeleton construction in the US, but on smaller structures, in particular extensions to existing buildings, penthouses, carports, schools and offices. Preferably, it focuses on one-story buildings.
  • US Pat. No. 7,823,347 B1 is known a steel profile, which is suitable for lighter structures. It is a tube to the outside evenly distributed four strips are set, which are in cross shape to each other. These strips have regularly arranged rows of holes. Said document describes wall panels which are arranged between two vertical steel profiles and are connected to these via additional mounting parts. There is a gap between the wall plates and the steel profiles.
  • Foam sheets are generally considered as filler. They are excellent in terms of thermal insulation, they are also very light in weight, but can absorb only small forces. For the latter, the steel skeleton is responsible.
  • the present invention seeks to provide a wall element of a building, which has an easy to create, from home tight connection between the plate and steel profile.
  • the adhesive seam Due to the adhesive seam, the plate and the adjacent steel profile are firmly and tightly connected.
  • the adhesive seam can be produced quickly and easily. A skilled worker can create several meters of adhesive seam in a short time.
  • a common construction adhesive is used, which is applied cold.
  • a polymer adhesive for example TEC 7 from Novatech N.V., Olen, Belgium, is used, which is applied with a pressure gun.
  • the positive connection between the support surfaces and the plate is effective, because so compressive stresses can be absorbed
  • the adhesive seam is effective, because they tensile and shear stresses can be transmitted. It is therefore not only important for the seal that plate and steel profiles are in direct contact, possibly via an intermediate adhesive seam, this direct contact is also advantageous for the load bearing.
  • the space between the two steel profiles is used to accommodate the plate.
  • Wall elements of the type described can be created relatively quickly, the installation is simple and feasible with less experienced craftsmen and with little effort on tools.
  • the wall element can be further processed outside and inside by conventional methods, for example by applying an additional outer or inner plate, as in Fig. 5 of the WO / BE2013 / 000030 A1 , a protective layer, an acoustic insulating layer, etc .. Interstices between the narrow surfaces of the plate, the adhesive seam and the steel profile allow the insertion of electrical cables, etc ..
  • the hard foam board has a thickness at least equal to the width of the support surface.
  • the thickness of the foam plate is equal to the width of the steel profile.
  • the thickness of the foam sheet is in the range between the width of the support surface and the width of the steel profile. Thicknesses of the foam plate greater than the width of the steel profile are possible.
  • PS polystyrene rigid foam
  • EPS polystyrene particle foam
  • XPS polystyrene extruder foam
  • other foam materials for the plates are possible, for example Polyuretanschaum.
  • the wall elements can absorb significant deformations, so that they remain stable in particular during earthquakes.
  • the thermal insulation can be widely adapted to the respective requirements, due to the extensive Using sheets of foam, a large-area thermal insulation is achieved. Only for the steel carrier having a smaller area proportion must a special thermal insulation be provided, as is known from the prior art.
  • the insulation against noise, so the acoustic insulation can be achieved by special measures, such as additional insulating layers. Since the plates contribute to the stability of the wall element, can be dispensed with diagonal struts, etc., in any case, less diagonal struts are necessary than in the prior art and also in the event that no adhesive bond between the plates and the steel beams.
  • the hard foam board is surrounded on at least three sides by steel profiles and also connected to the third steel profile via at least one adhesive seam.
  • the plate is surrounded on all four narrow sides of steel profiles and connected all around at least one adhesive seam. The fact that the plate is clamped in a frame of steel beams, the overall result is a high load capacity of the device produced in this way.
  • the narrow face of the hard foam board is either in direct contact with a support surface of a steel profile or at a very small distance, e.g. 2 to 8, in particular 2 to 4 mm away from this support surface.
  • the plate should be slightly thicker than the width of the support surface amounts.
  • the plate is connected via a fillet weld of adhesive with the mounting surface directly adjacent to the support surface.
  • the adhesive fills the narrow gap between the narrow surface of the hard plastic plate and the support surface. It is advantageous to arrange previously small spacer elements between the narrow surface and the support surface, so before introducing the adhesive, the plate already has a predetermined, fixed position and the narrow gap is defined.
  • the steel profiles used in the WO / BE2013 / 000030 are described. They have four planes of symmetry, each determined by the longitudinal axis and either by an inner corner or by the middle between two adjacent outer corners.
  • This in FIG. 1 wall element shown has three rigid, parallel, supporting steel sections 20, which are identical.
  • This steel profile 20 has a longitudinal axis 22nd
  • the description uses right-handed x-y-z coordinate system.
  • the x-axis is parallel to the longitudinal axis 22.
  • the y-axis is parallel to the width of the wall element, the z-axis parallel to the thickness.
  • the profile shape of the steel profiles 20 used is, for example FIG. 2 seen. Since this shows in an oblique to the longitudinal axis 22 performed section, the cross section appears distorted.
  • the section plane II-II is parallel to the z-axis and at an angle of 45 ° to the x-axis.
  • a width B of the profile extends parallel to the y-axis and is equal in cross-section to the length L of the profile. The latter extends parallel to the z-axis.
  • the steel profiles 20 are open at both profile ends. They have a constant cross section over the length.
  • the cross section is in the yz plane.
  • the cross-section has a rotational symmetry of 90 °. It has eight right-angled outer corners 24 and four right-angled inner corners 26.
  • a support surface 28 Between two adjacent outer corners 24 is in each case a support surface 28. Overall, four support surfaces 28 are present. Between an outer corner 24 and the immediately adjacent inner corner 26 is in each case a mounting surface 30. There are a total of eight mounting surfaces available. All support surfaces 28 and all mounting surfaces 30 are identical, the surfaces 28, 30 are flat.
  • each mounting surface 30 a regularly arranged row of holes 32 is provided, which extends over the entire profile length.
  • the rows of holes 32 all run parallel to the x-direction.
  • the holes of parallel mounting surfaces 30 extending from the same support surface 28, are aligned.
  • the holes of all rows of holes 32 are each in common in cross-sectional planes, which are spaced apart in the distance of the holes in the x direction.
  • a plate 34 made of hard foam The foam has a deformation resistance in the compression test, namely compression stress at 10% compression, of more than 70, in particular more than 100 kPa and preferably more than 200 kPa.
  • FIG. 1 two such plates 34, which are identical.
  • the plates 34 have vertically extending narrow surfaces 36. They are parallel to the xz plane.
  • a narrow surface 36 in the immediate vicinity of a support surface 28 between both a gap 38 is present, which is two to eight, preferably two to four millimeters wide. He is filled with an adhesive.
  • the adhesive forms an adhesive seam 40 which completely fills the gap 38.
  • the three steel profiles 20 are interconnected by an upper profile 42 and by a lower profile 44 at their respective profile ends. These profiles have a longitudinal axis that is parallel to the y-axis.
  • fasteners are used, as described in the introduction WO / BE 2013/000030 are known.
  • the same profile material as for the steel profiles 20 is used. Overall, the arrangement of the steel profiles 20 and the upper and lower profiles 42, 44 forms in FIG. 1 a double frame. This limits two interiors. These are completely filled by the two plates 34.
  • the steel profiles 20 are first connected to the upper profile 42 and the lower profile 44, so that a skeleton is obtained.
  • a plate 34 is now each introduced.
  • spacer elements 46 are provided. These are narrow cuboids, which have the width of the gap 38. They are about 5 to 20 mm high in the x-direction, in the z-direction they have at least the dimension of the gap 38. Suffice per profile 20, 42, 44 a few such spacers 46.
  • the spacer elements 46 at least some of realized by two wedge-shaped parts that can be pushed together so that the distance can be adjusted and the plate 34 can be clamped in this way in the frame, which limits an interior space.
  • the aim is that the plates 34 are mechanically held firmly in the adjacent profiles 20, 42 and 44 before the adhesive is applied. This applies to all embodiments. In particular, the plates 34 are held between the steel profiles 20.
  • the plate 34 is in the frame, at least between two steel sections 20, positioned that it is fixed, but also so that the narrow surface 36 are aligned with the steel sections 20 and possibly the other profiles 42, 44, like this FIG. 2 shows.
  • the adhesive seams 40 can now be applied.
  • the adhesive seams 40 exclusively between the steel sections 20 and the narrow surfaces 36. They fill the column 38 from. It is possible to leave the spacer elements 46 in place, but they can also be removed if the adhesive seam 40 is made so far that the plate 34 is fixed even without the aid of the spacer elements 46. It is possible to fill the vacated space with adhesive after removal of the spacer elements 46.
  • the cross section of the profiles 20, 42, 44 has a width B and a thickness D of 75 mm.
  • the width of a mounting surface 30 corresponds to the width of a support surface 28.
  • the plates 34 each have a thickness that corresponds to the thickness D of the steel profile 20.
  • the access to a gap 38 or to the inner corners, in which the fillet weld is performed, remains free, because the adjacent mounting surface 30 is located in the z-direction by a third of the thickness D relative to the outer surfaces 50 of the plates 34.
  • These surfaces 50 lie on each side of the component in the same plane as the supporting surfaces of the same side running in the xy plane.
  • a plaster layer 48 which is applied to the surface 50.

It is used for acoustic insulation in the construction sector, see www.isola.be . It is polyurethane granules, which is summarized by means of a suitable adhesive to a mat.
  • the embodiment according to FIG. 5 essentially corresponds to the embodiment according to FIG. 2 , In contrast to the latter, the seam 40 is now not applied in one operation, but in two separate operations.
  • a first seam 58 is applied on one side as a fillet weld. Through them, the gap 58 is closed to one side. Specifically, it is closed in the embodiment on the inside of the device. The inside of the device lies in positive z-direction in front of the outside.
