Prefabricated house building steel structure frame

Abstract

The utility model discloses an assembly type house building steel structure frame, include: steel structure frame body, steel structure frame body is by first steel roof beam, second steel roof beam, pasting board, bolt and nut constitutes, the side of first steel roof beam is pasted with pasting board, the side surface fixedly connected with second steel roof beam of pasting board, the surface four corners of pasting board away from first steel roof beam all insert bolt. The utility model discloses the cooperation between steel structure frame body, first steel roof beam, second steel roof beam, pasting board, bolt and protection unit realizes the connection fixed, and the specific operation is as follows: the elastic force of clockwork produces the reaction force, and this force will exert an identical force with bolt and nut fastening rotation direction to the groove block, like this, when encountering the vibration in the subsequent use, can effectively avoid the loose condition of connection, prevents the stability of house building steel structure frame from reducing because of the loosening of connection, thereby guaranteeing that house can use safely.
