Bolt with clamp spring and enclosed profile connecting structure adopting bolt to connect

Abstract

The invention belongs to the technical field of machinery and profile connection, and particularly relates to a bolt with a clamp spring and an enclosed profile connecting structure adopting the bolt to connect. The bolt includes a bolt body formed by a head part and a screw, and the clamp spring is arranged at the head part in a matched way. The enclosed profile connecting structure is characterized by including a closed profile, a connecting plate and the bolt with the clamp spring; the bolt with the clamp spring includes the bolt body formed by the head part and the screw, the clamp spring is arranged at the head part in matched way; one or more through holes matched with the head part in shape are formed on the closed profile; a screw hole is formed on the connecting plate; the head part is pushed into the through hole of the closed profile and rotated for 45 to 90 DEG to be locked and limited; the bolt penetrates the screw hole of the connecting hole to be locked through the nut; and the other side of the connecting plate is connected with the profile bolt. The bolt with the clamp spring and the enclosed profile connecting structure adopting the bolt to connect are reliable and firm to lock, are convenient to mount and dismount, remarkably improve the construction efficiency, and reduce the safety hazards like fire accidents.

Description

technical field [0001] The invention belongs to the technical field of connecting mechanical parts and profiles, and in particular relates to a bolt with a clip spring and a closed profile connection structure connected by the bolt. Background technique [0002] At present, in the field of building curtain wall, factory building support structure, and shelf structure, if closed profiles (such as rectangular steel pipes) are used as the connection structure for the connection between steel structure columns and beams, welding connections are generally used, and bolt connections cannot be realized. The reason why the bolt connection cannot be realized is that the profile is a closed structure, and the bolt cannot be placed in the connection position, because the size of the bolt head is larger than the threaded hole diameter on the profile. Welded connections affect the welding quality of outdoor projects, poor anti-corrosion ability, and fire accidents often occur. Contents...
