摘要

The construction system has its main bearer (3) connected to its supports (1) so that two flat steel strips can be screwed to it and then spread by a threaded stud, thereby making a connection with the supports which is rigid against bending. The supports are anchored to the foundation (2) and slotted to take the main bearer.
