Description

TITLE OF THE INVENTION

A building wall panel and a wall structure including such a building wall panel

FIELD OF THE INVENTION

The invention relates to a building wall panel to be connected with a skeleton frame structure for erecting a wall, comprising a web to be mounted with one side thereof against said frame structure and having two opposite edges parallel with each other, a first flange at one of said edges, and a second flange at the other one of said edges, said first and second flanges projecting substantially perpendicularly from the other side of said web.

The invention also relates to a wall structure including wall panels of the kind referred to above.

PRIOR ART

A building wall panel of the kind referred to above is disclosed in DE G 86 16 637.9 Ul. The flanges of this prior art building wall panels terminate in edge lips extending along the flanges and projecting therefrom in the same direction and substantially in parallel with the web. PROBLEM TO BE SOLVED

The shape of the prior art building panels prevents stacking of the panels for shipping with one panel nested into the other. This means that the bundle of panels as stacked is very bulky and that a great percentage of empty space, i. e. air, has to be transported at shipping, which makes shipping very uneconomic. There is also a risk that the panels are distorted or damaged when stacked to form a bundle .

BRIEF DESCRIPTION OF THE INVENTION

In order to overcome the problem accounted for above while maintaining such a design of the building panel which does not impair the mounting of the panel on the supporting frame structure and does not render the manufacture thereof difficult, the invention provides a building panel of the kind referred to above which according to claim 1 is characterized in that said second flange is a double-wall flange defining an interstice between the walls thereof, said interstice opening on said one side of the web to receive therein said first flange of an adjacent building wall panel.

The wall structure including the building wall panels of the invention comprises a skeleton frame each of said panels being mounted with one side of the web against the frame, said first and second flanges projecting substantially perpendicularly from the other side of the web, the interstice formed between the walls of the double- wall flange opening on said one side of the web and receiving therein said second flange of an adjacent building wall panel mounted to said frame.

Preferred details of the invention are defined in the dependent claims .

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be described below in more detail with reference to the accompanying drawings which disclose illustrative embodiments of the invention and in which

FIG 1 is a fragmentary vertical cross sectional view of a wall structure including building wall panels of the invention, FIG 2 is an enlarged fragmentary vertical cross sectional view of two adjacent interconnected building wall panels, and

FIG 3 is a vertical cross sectional view of a number of building wall panels stacked one upon the other to form a relatively compact bundle suitable for shipping.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The building wall panel of the invention preferably is made of metal sheet such as aluminium sheet or galvanized steel sheet, or of any other suitable material. The sheet material suitably has a paint coating on at least the side thereof which is visible in the completed wall structure. The wall panel includes a planar web 10 formed with stiffening grooves 11 which are shown with triangular cross sectional shape but can have any other shape and also can be dispensed with. Instead of having grooves the web can be formed with one or more stiffening steps. At two opposite mutually parallel edges of the web the panel forms flanges 12 and 13 which project substantially at right angles from one side 14 of web 10. Flange 12 joins the web at an angled portion 15 which forms a bevelled corner between flange 12 and web 10.

Flange 13 at the other one of said parallel edges of the web is a double-wall flange produced by double folding of the metal sheet. The walls of the flange are designated 16 and 17. At the outer end flange 13 forms a lip 18 projecting at right angles from the flange and terminating at a bevelled edge 19 where walls 16 and 17 are integrated. Walls 16 and 17 of flange 13 depending on the manufacturing technique in some portions abut each other and in other portions define an interstice 20 which opens at the other side 21 of web 10. Generally there is an interstice the width of which is near zero and may be of the same order as the metal sheet thickness which ranges from 0.7 to 1.5 mm. Walls 16 and 17 of flange 13 diverge over a portion close to the opening of the interstice at 22 at the same angle as that formed by portion 15.

FIG 3 illustrates how building wall panels as described can be stacked to form a bundle by laying one wall panel on the other the panels being nested in each other. As will be seen there is a minimum empty space between the panels, the height of which is determined by the length of flange 12. Flange 12 can be made rather short and should be made only so long as is necessary in order to allow interconnection of adjacent wall panels as shown in FIG 2. The bundle of panels thus is rather compact. When a wall shall be erected by using the building wall panel described a skeleton frame is first erected. This frame can comprise vertical pillars 23, FIG 1, of wood, steel or reinforced concrete, which may be interconnected by horizontal connecting elements or not. The skeleton frame can be of any type forming a load- carrying structure. Building wall panels as described are attached to pillars 23 by means of screws 24 or any other suitable fastening elements with side 21 of web 10 engaging the pillars. The wall panels are oriented such that flange 13 of each element forms the upper substantially horizontal end surface of the element, the opening 22 of interstice 20 of the panel being directed towards the load carrying structure 23. Flange 12 of an adjacent wall panel is inserted into interstice 20 of flange 13 and is attached to this flange by means of a screw 25 or any other suitable fastening element. Screw 25 thus connects the two adjacent wall panels with each other. A sealing tape 26 is passed onto the screw to seal between flange 12 and wall 16 of the double-wall flange 13 so as to prevent moisture to penetrate into interstice 20 of flange 13. Sealing means of any other suitable type can be provided in order to close interstice 20 towards the surroundings.

When the wall panels have been mounted to the load carrying structure 23 the space defined by surface 21 of web 10 and flanges 12 and 13 is filled with a light-weight soft and resilient heat insulating and sound absorbing material 27 such as mineral wool. Also foamed polymer e. g. polystyrene or polyurethane or any other suitable insulating material can be used. The outside of this material is covered by a corrugated exterior sheathing plate 28 or any other suitable type of exterior sheathing which forms a facade panelling and is connected with lip 18 by means of screws 29 or any other suitable fastening elements. In case of a corrugated sheathing the corrugations may extend vertically or horizontally.

The heat insulation can be of the type which includes an outer layer 27A of water-repelling and wind-proof character having a higher density than the rest of the insulating material. As an alternative a windbreak plate can be installed between the insulation and the exterior sheathing. In order to avoid that a thermal bridge is established between the sheathing plate 28 and the wall panel, lip 18 is inserted into the insulating material and preferably is located therein between the layers of different density.
