Description

Technical field

The invention relates to a cassette wall for the cladding of load-bearing structures, in particular production, storage or commercial halls, comprising stacked cassettes with uprights made of a thin-walled C-profile, the cassettes being oriented open side away from the load-bearing structure. and the cassettes are covered with cover sheets.

BACKGROUND OF THE INVENTION

Cassette walls are used in the construction industry for wall cladding, especially for production, but also warehouse or commercial buildings. The use for the construction of roofs is also not excluded.

The advantage of the cassette walls is the fast closure of the building from the weather effects on other work taking place inside. Another advantage compared to wall thermal insulation sandwich panels is the greater thickness of the sheet than the cassette itself (usually 0.75 mm, at larger spans, ie at greater column distances of 0.88 - 1.5 mm) and trapezoidal or corrugated sheet forming the facade ( typically 0.63 or 0.75 mm) compared to a sandwich having a sheet thickness of 0.5-0.6 mm outer / 0.4-0.5 mm inner.

Known cassette walls for cladding support structures include stacked cassettes, each of which is of a thin-walled C-shaped sheet metal support, the cassettes oriented open side away from the support structure, and the cassettes contain thermal insulation boards. The cassettes are covered with cover sheets, which are insulated from the ends of the cassette strips only by self-adhesive thermal insulation tape. Such insulation is virtually of no importance in view of the ventilated air gaps between the cover plates and the insulation in the cassettes, and linear thermal bridges are formed.

This drawback is partially eliminated by the construction, commercially available under the name Rockprofil, based on the use of special spacers and mineral insulation surrounding the cassette struts. The disadvantage is the need to use different thicknesses of mineral insulation boards.

An essential property of the perimeter wall is its thermal resistance R, expressed as the inverse of the heat transfer coefficient U.

The known cassette walls described above have about 1.00 at a cassette depth of 120 mm R. The Rockprofil system at the same cartridge depth has a U = 0.281 µ. R approaching 4.

From the Czech utility model 19243, a cassette wall is known for cladding load-bearing structures, in particular production, warehouse or commercial halls, comprising superimposed cassettes, each of which is made of a thin-walled C-shaped sheet metal support. The cassettes are oriented open side away from the supporting structure and the cassettes contain the thermal insulation boards. The cassettes are covered with cover plates. Vertical thermal insulation strips are placed between the cover plates and the cassettes, and horizontal thermal insulation strips with a density of 120 to 220 kg / m ³ are inserted between the cover plates and the vertical thermal strips at the free ends of the cassette struts.

The aim of the technical solution is to design such a cassette wall construction which, by suitable arrangement of thermal insulation, achieves significantly better values of thermal and acoustic resistance than known constructions.

The essence of the technical solution

This problem is solved by a cassette wall for the cladding of load-bearing structures, in particular production, storage or commercial halls, comprising stacked cassettes with uprights of a thin-walled C-profile, stacked with the open side facing away from the load-bearing structure. the cassettes are covered by cover plates, according to a technical solution which comprises thermal insulation comprising a glass wool board in a cassette, the thickness of the glass wool board being smaller than the height of the cassette web and a stone wool board having a thickness of it extends beyond the ends of the cassette struts, the cover plate being fastened to the cassette struts by spacers.

The cassette wall according to the invention has a heat transfer coefficient of U = 0.276 and a fire resistance of EI 45, EW 120, which are significantly better values than in the known solutions. Combination of glass wool and stone wool boards, according to the technical solution, the cassette wall has excellent acoustic properties. In addition, a single standard thickness of stone wool slabs can be used for all cassette walls in combination with three standard thicknesses of glass wool slabs.

According to a preferred embodiment, the cover sheet comprises trapezoidal sheet and / or corrugated sheet.

BRIEF DESCRIPTION OF THE DRAWINGS

A cassette wall for cladding the supporting structures according to the invention will be described in more detail by way of example of a specific embodiment, shown schematically in FIG. First

EXAMPLES

The cassette wall of FIG. 1 serves for the cladding of concrete or steel load-bearing structures of 8 production, storage or commercial halls. The cassette wall is formed by stacked cassettes 1, each of which is made of a thin-walled C-shaped sheet metal profile with a sheet thickness of 0.75 mm and a cassette depth of 120 mm. The cassettes 1, in this case cassettes commercially available under the designation Metal Profiles K 120/600 / 0.75, are oriented open side away from the supporting structure 8 and are fixed against each other by shaped locks formed on the webs 6 of cassettes 1 and self-tapping screws 7th

Each cassette 1 houses a glass wool plate 2, in this case an 80 mm thick Knauf Insulation TP112 fiberglass insulation.

The thickness of the glass wool plate 2 in the cassette 1 is less than the height of the cassette web 6 The stone wool board 4 rests on the surface of the glass wool board 2, the thickness extending beyond the ends of the cassette webs 6. 4. The stone wool 4 in this case is Knauf Insulation FRE-P with a constant thickness of 80 mm.

The cassettes 1 are externally covered with cover sheets 3, formed by a trapezoidal sheet of 0.63 mm low-wave thickness, in this case a trapezoidal sheet commercially available under the designation Metal profiles TR 35. The cover sheet 3 is fixed to the webs of 6 cassettes 1 by spacer screws 5th

The described cassette wall construction according to the technical solution has a heat transfer coefficient U = 0.276 and a fire resistance of EI45, EW 120.

In assembling the cassette wall, the cassettes 1 are first mounted by means of self-tapping galvanized screws 7 via a PUR compression tape on the steel substructure 8, eventually, using plastic-coated screws in a plastic-coated construction on the concrete substructure 8 or using injection nails on both types of substructure 8.

The webs 6 of the cassettes 1 are provided with sealing tape at the points of mutual contact and the webs 6 are connected to each other by self-tapping galvanized screws in the back third of the depth of the cassettes L

Fibers of glass wool 2 whose thickness is less than the height of the web 6 of the cassette L are inserted into the cassettes 1 so fastened. Glass wool boards 4 are placed on the glass wool 2 boards with a thickness exceeding the ends of the webs 6 of the cassette 1. the end of the upper web 6 buried in the stone wool board 4.

The trapezoidal cover plates 3 are then mounted, usually vertically, on the structure thus prepared, by means of spacers 5.

Regardless of the name of the technical solution - cassette wall - it is obvious to the skilled person that the use in the construction of roofs is not excluded either.
