Abstract (en)

[origin: EP0933488A2] The frame members (1) are joined at their ends by matching corner pieces (2) in a butt joint held together with bolts (21). The joint face (22) has a groove (31) into which a slightly protruding sealing strip is fitted. The strip is shaped to follow the outline of the section and is compressed as the bolts are tightened.
