Abstract

The invention relates to joints of ira continuous process produced, both sides with metal coated plastic foam boards for cellular , Buildings, in particular for cold rooms, cold stores and climatic chambers. It is the object of the invention to provide a heat bridge-free, dense, from one side mounted and dismountable, form and create positive connection. The essence of the invention is that a spring 5 in a narrow side of the Building board 1.2 wedge-shaped incorporated IJut 3 is inserted and that the spring 5 is a molded part 9 with two separate Internal thread inserts 17 receives, in each of which a pressure plate 7, 11 penetrating connecting pins 8, 10 of the / outer sides intervenes. When tightening the connecting pins 8, 10 is the Grooved cheek 3 pressed against the spring 5 and a good sealing effect achieved "

invention description

Title of the Invention Joint connection for structural panels

Field of application of the invention

The invention relates to joints of joint-produced, on both sides with metal, coated plastic hard foam construction boards, which are used as Y / and-, balustrade, floor and ceiling panels for cell-like buildings in industry, agriculture and society use. Preferably, they are used for cold rooms, cold stores, climatic chambers and wherever a temperature difference between the room air and the outside air must be maintained ·

Characteristic of the known technical solutions

Known joints for multilayer building boards (DL PS 72 564 and 98 968). have on the narrow sides on both sides of an S-shaped fold formed by the cover sheet layers, in which engage the legs of each cover profile ·

Since the connecting bolt projects beyond the cover sheet layers, it forms a thermal bridge, so that such joint connections are unsuitable for use in cold rooms or other thermally stressed rooms The joint gap iat designed with "rigid foam strips and brings for the cooling cell construction thus not yet the required tightness, so that it may come to ice formation in this area · The screwing of the building panels takes place from both sides ·

Object of the invention

It is an object of the invention, the building boards produced in a continuous process on highly productive plants, which were previously used as wall and roof elements for hall-like buildings in Metalleichtbauv / iron for industrial, agricultural technology and society, also for wave-like buildings to maintain a temperature difference between the room air and the outside air, preferably for cold storage, to make usable.

Essence of the invention;

The invention has the object of providing the joint connection in such a way that a heat bridge-free, dense, form-fitting and non-positive connection can be assembled and disassembled from only one side «

The features of the invention are that a spring "with largely diffusion-tight cover layers in a wedge-shaped in the narrow side of the building board groove

is inserted and that the spring receives an axially movable molding made of plastic or other material with poor thermal conductivity with two separate internal threads, in each of which engages a pressure plate penetrating a connecting bolt from the outer sides. The printing plates grip: with their thighs in the s-shaped narrow side profiling of the building boards. When tightening the connecting bolt, the liutwange is pressed against the spring and thus achieved a good sealing effect. To ensure the required freedom of movement, which would otherwise be limited by the edge profiling of the cover sheet of the building panels to be joined, possess the "edges of the faces of the molding wide" chamfers. Through this design of joint connection is a heat bridge-free, easy and mountable from one side force and positive connection achieved ·

embodiment

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawing shows a section through a butt joint of the building boards ·

In one of the two structural panels to be joined 1, 2 with the slightly wedge-shaped groove cheeks 3, the connecting element, consisting of the outer joint profile 4, the spring 5, the inner joint profile 6 and a corresponding number Verschraubungelemente consisting of outer pressure plate 7 with square punched, round-head screw 8, molded part 9 made of plastic with two insert chambers with internal thread inserts 17 and central bore, hexagon screw 10 and inner pressure plate 11 introduced. "The joint profiles 4 and 6 in the association of the entire connecting element must be spread so far that they on the s-shaped folds 12th the building board 1 can be pushed ·

For this purpose, the hexagon screw 10 is turned out as far as possible. In order to enable the pressure plate 7 to be grasped over the folds 12 of the plate 2 to be mounted next, the entire screwing mechanism must be moved outward, ie. H. be moved in the direction of just this pressure plate 7. The freedom of movement of the molded part 9 would, however, already limited after a short displacement by the rolled-up outer cover sheet layer 13. In addition, to ensure the required freedom of movement, wide chamfers 14 are attached to the front and rear edges of the molded part 9. This is the described spreading of the joint profiles 4; 6 secured. Now, the building board 2 is introduced into the connecting element and made by means of socket wrench via a bore 15 in the joint profile 6, the non-positive and positive connection. Here, the wedge-shaped IJutwange 3 applies to the spring 5. The bore 15 is covered with a cap 16.

Claims (2)
