The present invention is a method for forming load-bearing joint s through the use of a compressed cellular plastic material (3) having a stable form at room temperature, and which, after insertion into the joint area (1), is made to expand through heating so that the whole of the joint area is filled. Bonding between the filler material and the base material can be secured by means of a hot melt adhesive or a hot melt adhesive with setting agent (4) which, during the expansion phase of the filler material, melts under elevated temperature, and thereby a bond is formed between the filler material and the base material (5). Through this method, when the filler material heats up, the joint area is filled, pressure is exerted on the adhesive, and bonding to the base material is secured at one and the same time. With the present method, the components comprising the joint are dry when being handled. The method is applicable for the load-bearing joining of core material in sandwich constructions. It can also be used for joining concrete panels, wall panels, window panels, etc. in building construction. |
