Self-locking bolt assembly for cold-formed thin-walled steel structure anti-pulling piece and installation method of self-locking bolt assembly

Abstract

The invention discloses a self-locking bolt assembly for an anti-pulling piece of a cold-formed thin-walled steel structure and an installation method thereof.The self-locking bolt assembly comprises a first self-locking bolt set, and the first self-locking bolt set is arranged on a wall side column connected with a web of the anti-pulling piece and comprises a first base, a first bolt and a first metal ball; a horizontal channel threaded hole is formed in the first base, a first cavity is formed in one end of the horizontal channel threaded hole, a first hole channel is formed in the first bolt, a first round hole communicated with the first hole channel is formed in the side face of one end of the first bolt, and the first metal ball is arranged in the first round hole. The end, provided with the first round hole, of the first bolt is screwed in from the end, away from the first cavity, of the horizontal channel threaded hole, and a self-tapping screw of the anti-pulling piece web penetrates through the wall side column and is inserted into a first hole channel of the first bolt through the first cavity. The anti-pulling piece self-tapping screw is prevented from loosening and falling off under the action of strong shock, and the connection reliability and lateral resistance of the anti-pulling piece are improved.

Description

technical field [0001] The invention relates to the technology of prefabricated house fittings, in particular to a self-locking bolt assembly used for a cold-formed thin-walled steel structure pulling-resistant part and an installation method thereof. Background technique [0002] Cold-formed thin-walled steel structure buildings have been vigorously promoted in low-rise buildings in recent years based on their advantages of short construction period, superior seismic performance and environmental protection. Because earthquake disasters are frequent and harmful, ensuring the stability of the connection between the multi-storey cold-formed thin-walled steel structure building and the foundation has become the key to the success or failure of the structure to resist earthquake damage. However, the structure of the traditional pull-resistant parts is thin, and the pull-resistant parts will bear severe stress conditions under the action of strong earthquake or large wind force,...

AI Technical Summary

Problems solved by technology

However, the structure of the traditional pullout-resistant parts is thin, and the pullout-resistant parts will bear severe stress conditions under the action of strong earthquakes or strong winds. There will be problems such as self-tapping screws loosening and pull-out anchor bolts being pulled out. The connection effect is poor and cannot Meet the need for a solid connection between the overall structure and the foundation
