Problems solved by technology

[0002] At present, in the field of building curtain wall, factory building support structure, and shelf structure, if a closed profile (such as rectangular steel pipe) is used as the connection structure for the connection between steel structure columns and beams, welding connection is generally used, and bolt connection 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 on the connection position, because the size of the bolt head is larger than the threaded hole diameter on the profile
Welding connections affect the welding quality of outdoor projects, poor anti-corrosion ability, and fire accidents often occur

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0023] As shown in the figure, the bolt with a circlip includes a bolt body composed of a head 1 and a screw rod 3 , and the head 1 is matched with a circlip 2 . The head 1 of the bolt body is provided with a boss 101 , and the ring 2 is correspondingly provided with a boss hole 201 for snap-fitting with it. The jumper 2 can also be directly welded on the head 1 of the bolt body. The length of the widest part of the bolt body head 1 in the transverse direction is greater than the length of the widest point in the longitudinal direction, and the limitation of the head length is beneficial to the rotation limit of the bolt body head 1 . The bolt body head 1 can be rectangular, prismatic, elliptical or other structures conforming to the widest point with different lengths and widths. The head 1 of the bolt body can be rectangular, and the bolt is a...

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...
