Construction system for watertight connection of expandable structures

摘要

The construction system comprises of at least two profiled sections (1) situated parallel to the expansion gaps. The sections are of T, L, U or I-shape. Walls of between one and four corner spaces (2) are formed. At least one wall has a pair of clamping elements (6) with a gap between them. Each element is offset from the corner and has the same length as the steel beam. The element has a bent surface, and may have an additional straight surface. The elements form a groove in which a watertight sealing membrane (8) is clamped, and that extends between adjacent beams.
