Connection of components and processes for the production of the

link

The invention relates to the connection of devices and a method for preparing the compound and, in particular like a removable connection of devices and a method for preparing such compounds, so that two or more components can be quickly assembled and disassembled. Such a need exists in the field of movable houses, portable houses, and composite houses.

The use of building elements to erect makeshift offices, houses, dormitories and the like has been around since Practiced for a long time, especially for industrial purposes. With such a building structure, two or more Components transported separately to the installation site and assembled there to form a finished structure by the elements * fastened together by bolts or in any other way. A major problem in assembling such structures has been in sealing the connection between two elements, especially in the roof areas. This problem becomes exacerbated by the fact that such components have to offer resistance when they reach temperatures from -57 ° C to + 82 ° C. Components produced in the same plant can be used in the northern areas, for example from Alaska, where temperatures are below -57 ° C, to the desert areas of Saudi Arabia, where temperatures up to + 82 ° C can be reached. The problems

the connection of separate elements in a catfish, which are the same enabling them to remain in permanent connection or to be quickly disconnected for transport are largely remained unsolved. In all previously available methods, the connections of such components were in extreme heat and cold destructive or difficult to apply and remove.

The present invention provides a solution to the problems of sealing joints in movable houses, portable ones Structures and structural elements. By practicing the invention, two or more components can be attached to their interconnection quickly sealed and just as quickly released from each other without damaging the components, so that the same Can be transported to a new site, where they can be reassembled without damage and at very little cost will.

Preferably there is a pair of structural members to be joined, a pair of surfaces abutting their edges, a band of mechanically strong material along each edge and an inner band of soft conformable self-sealing elastomer on the band of mechanically strong material, the band made of self-sealing elastomer is self-sealing and on a prepared surface. The sealing tape is preferably an elastomer that can be squeezed out under pressure and is sensitive to adhesive pressure and is self-sealing, such as, for example, natural rubber, styrene-butadiene rubber, butyl rubber, neoprene, nitrile rubber, polysulfide rubber, ethylene-propylene copolymer, terpolymer and similar materials, the so are composed to be soft, conformable and self-sealing. The outer tape or layer of mechanically strong material is preferably a strong, tough, elastic film or foil such as polyethylene, polypropylene, cellulose acetate, polyolefin, polycarbonates, polyesters, polyvinyl chloride polymers, polyvinyl fluoride polymers, aluminum foil and similar materials.

A structure that has two separate structural elements next to each other Has surfaces which abut with two edges, is characterized according to the invention in that a continuous layer of soft, conformable, self-sealing Elastomer is attached to the same along each abutting edge and that an outer layer of mechanically solid material covers the abutting edges and is held in place by the elastomer.

In the foregoing general description, particular objects, purposes, and advantages of the invention are set forth. Further Objectives, purposes and advantages of the invention will become apparent from the following description with reference to the drawing, " in which shows:

Fig. 1 is a partially perspective view of a pair of structural members before they are connected;

guiding stands. The film 14 can be any flexible film that provides high strength and resistance to breakage and tearing extreme temperatures. Such a material can be a metal foil, such as aluminum foil, or a Synthetic resin film such as polyvinyl chloride, polyvinyl fluoride, polyethylene, polypropylene or the like. The glue layer 15 can be made of natural rubber, styrene-butadiene rubber or another self-sealing elastomer mentioned above.

Fig. 3 shows a cross connection 20 which is formed by bending the edges 21 of adjacent elements around a sliding bracket 22, which is provided with an inner layer 23 of a self-sealing elastomer. On top A layer 24 of a self-sealing elastomer and a tape is applied to the joint, as described in the above Way of an outer layer 25 of a mechanically strong material and an inner layer 26 of a self-sealing material Elastomer.

The components can be moved by simply slitting the film layer along the joint, whereupon the Components are transported to their new site, the film is peeled from the elastomer layer and on new installation site over the connection a new film 14 and an adhesive layer 15 made of elastomer is placed.

In order that the nature of this invention may be better understood, the same will be illustrated by the following examples of a mechanically strong one Film and a self-sealing adhesive applied thereto.
