DRYWALL CONSTRUCTION COMBINATION PROFILED SECTION FOR WALLS AND CEILINGS OF A HOUSE AND METHOD FOR ERECTING A DRYWALL CONSTRUCTION WALL

Abstract

A wall construction system having drywall construction combination profiled sections, and a method for constructing a wall. Standard drywall construction profiled sections using sheet metal that is approximately 0.6 mm thick allow easy manual sheathing of stud walls with building panels, but lightweight sheet metal profiled sections of this type are not suitable for bearing static loads of a house. Thicker walled lightweight steel profiled sections greatly improve stability but require more costly assembly technologies needing specialists, which increases construction costs and therefore stops drywall-constructed housing from becoming more widespread. The new combination profiled sections provide for statically stable construction systems that can nevertheless be worked and sheathed simply and easily. The present drywall construction combination profiled section includes two functional sections. A statically stable section which has splayed flanges, and a section having a planar thin-walled drywall construction contact surface, acting as a sheathing section.

DETAILED DESCRIPTION

[0031] FIG. 1: the exemplary embodiment shows horizontal cross sections through a drywall construction wall with three different drywall construction combination profiled sections (1) which are set vertically and anchored as wall studs in horizontal U foot and U head profiled sections. The outer building panel (4) serves primarily for structural wall reinforcement and consists of an OSB panel coated with insulating materials and is part of a wall body (5) which is screwed from the inside to the static section (2) of the drywall construction combination profiled sections (1).

[0032] The wall bodies (5) with the dimensions of approx. 60 cm250 cm and peripheral tongue and groove system are plugged together in a horizontal offset with the profiled sections overlapping and are screwed to the static sections (2) of the wall inner side. In the area of the storey ceiling, a wall body (5) overlaps both the studs of the ground floor and of the first floor. The outer insulating layer also serves as a plaster base for the facade.

[0033] In the construction process, first of all all of the drywall construction combination profiled sections (1) are produced at their static sections (2) with the U foot and U head profiled sections in the form of a house framework by specialized fabricators and structurally connected to one another. All of the connecting points are accessible on all sides with specialized tools of the trade. Subsequently, other surfaces take on the claddings of the combination profiled sections. Only after the room-interior installation of installations and sound protection mats are building panels (4) as interior finish screwed at a subsequent time to the thin-walled cladding sections (3). The same construction can in principle also be used for ceiling and roof structures.

[0034] FIG. 1a: in the static section (2), the drywall construction combination profiled section is a modified Z profile composed of steel sheet with a room-side folding having the thickness of 1.6 mm and with a drywall construction contact surface (8) additionally integrally formed on the room side as a cladding section (3) composed of steel sheet of a thickness of 0.65 mm. The folding of the static profiled section stabilizes the flange and reduces the profiled section width. The sheet metal band semifinished product is a longitudinally welded sheet metal strip of different thickness (tailor welded coil), wherein the static section has a yield strength of approx. 600 N/mm.sup.2.

[0035] In the static section of the combination profiled section (1), the outer drywall construction contact surface is provided throughout with a pattern of holes, and therefore the screw connections to the wall bodies (5) can take place there from the inside at selected perforations. All of the perforations can be achieved non-critically using tools of the trade.

[0036] On the same drywall construction contact surface, there are relatively large perforations at a greater spacing, into which facade holders or roof holders (6) are inserted, optionally from the inside, and anchored. Said holders take over the introduction of load from local facade loads or roof loads into the static section of the drywall construction profiled section. Said facade holders (6) having any desired structure are anchored from the inside to the drywall construction profiled section during the process of constructing the wall.

[0037] In the static section (2), the combination profiled section of FIG. 1b is a Z profile composed of steel sheet having the thickness of 2.5 mm, which is connected to a storey-high, separate, thin-walled drywall construction profiled section in a form-fitting manner as a cladding section (3). Deflected local tabs of the thin-walled profile (3) engage in suitable punched-out portions of the Z profiled section web and are hooked therein. On account of the accessibility, the cladding section (3) is only hooked in after the outer reinforcing cladding (4) is fastened to the static profile. In particular in the event of large differences in thickness of the two combination profiled sections, separate profiled section parts are necessary for manufacturing requirements.

[0038] The combination profiled section (1) of FIG. 1c is also composed of two separate profiled sections; of a static hat profiled section (2) and a thin-walled C profiled section (3) which is inserted in a flush and form-fitting manner therein and the two parts of which are fixed by means of a plurality of screw bolts (7). Here too, the C profiled section is only fitted retrospectively after the outer cladding (4) is attached.

[0039] Between the outer cladding (4) of the stud and the facade surface, a facade support strip (12) is applied perpendicularly to the static profiled section (2) and fastened from the inside. Said facade support strip is a high-strength insulating material strip which, at the grid spacing of the wall studs, absorbs the facade forces and introduces the latter into the static drywall construction combination profiled section. Suspended facades are primarily supported thereon and can also be fastened thereto.

[0040] FIG. 2 shows the cross section of a drywall construction combination profiled section for ceilings or roofs without the claddings on both sides. Here, two combination profiled sections with a statically load-bearing C profile (2) which are each produced from a tailored coil are connected in a form-fitting manner. The thin-walled cladding sections (3) are in each case only integrally formed on the lower flanges or static sections and belong to the same sheet metal band semifinished product of the combination profiled section. The thin-walled cladding section (3) is located in the wall plane parallel next to the static section (2) of the individual combination profiled section and in a drywall construction contact surface offset in parallel.

[0041] FIG. 3: the shown cross sections of the combination profiled sections (1) are illustrated without claddings and consist of profiled section flange sections of different material thicknesses. The combination profiled section of FIG. 3a with the different thickness sections (2) and (3) is thus roll-formed from only one steel band semifinished product, the thin-walled sections of which have been produced by additional rolling (tailor rolled coil) or the sections of which have been produced by welding together sheet metal strips of differing thickness (tailor welded coil). The edge zones (3) which are thin-walled on both sides have a thickness of 0.65 mm, and the static load-bearing C profiled section (2) has a thickness of 1.6 mm. The contact surfaces of the drywall construction cladding for both profiled sections are located on both sides in the same wall plane, and therefore easy connection to the U foot and U head profiled sections is provided. For considerations in terms of sound, only the cladding sections (3) can also lie in an offset wall plane.

[0042] FIG. 3b: the drywall construction combination profiled section (1) having a static I structure has only one integrally formed thin-walled cladding section (3) as part of the drywall construction contact surface (8) on a flange side.

[0043] FIG. 3c shows a drywall construction combination profiled section (1) having drywall construction connecting surfaces of differing thickness in each case on both sides, said drywall construction combination profiled section being produced by the linear flow splitting manufacturing method. In the case of this sheet metal forming process a steel sheet band of, e.g., a thickness of 3 mm is split on both sides into a sheet metal section (3) of a thickness of 2.3 mm (2) and a thickness of 0.7 mm and the split sheet metal halves of which were subsequently profiled.

[0044] All of the combination profiled sections of FIG. 4 are produced from an identically thick galvanized steel sheet band with a thickness of 0.6 mm to 0.7 mm by roll forming, with the static profiled section flanges of which being reinforced by material concentrations. Only the cross sections of the drywall construction combination profiled sections are illustrated.

[0045] FIG. 4a shows a C-like profiled section having thin-walled connecting surfaces (3) on both sides at the edge zones of the flanges. Directly next to the web, the load-bearing flanges are tightly folded in a meandering form in order to significantly increase the steel portion in said area and therefore the load-bearing capability of the static section (2) of the combination profiled section (1) with the same material thickness. As a result of the intrinsic stability of the flange areas, the thin-walled profiled section web which is reinforced with beads is sufficient. The profiled section height is, for example, 125 mm in cross section and the height of the meanders is approx. 25 mm. The folded meandering sections adapt with particularly little stress to uneven support.

[0046] The combination profiled section (1) of FIG. 4b with flanges (2) folded in a meandering form and in each case a central cladding section (3) is, as a hollow profiled section, particularly stable in terms of buckling and is particularly suitable for load-bearing inner walls. All four outer surfaces can be clad. During the manufacturing, the free profiled section flanks are welded, or two halves are joined.

[0047] The combination profiled section (1) of FIG. 4c has material concentrations at the statically load-bearing flanges by means of blocked multiple layers of a sheet metal band parallel to the drywall construction contact surface in order to act as a static section (2) of the combination profiled section. For easier installation of the building panels, the cladding sections (3) are located directly laterally next thereto, optionally in in each case a different wall plane.
