Problems solved by technology

When fastening the fastener, the steel pipe is clamped in the fastener, the bolt is clamped into the bayonet of the fastener, and then the nut is turned until the two ends of the fastener are fastened; but during the connection process, due to the bolt If the bayonet is not tightened tightly, the bolt will easily slip out of the bayonet, which will not only repeat the clamping, but may even cause the steel pipe to slip out

Embodiment Construction

[0008] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0009] Such as figure 1 Shown: the embodiment of the present invention provides a bolt for building fasteners, including a T-shaped bolt 1, a U-shaped clip 3 and a nut 2 connected to the T-shaped bolt 1, and the U-shaped clip 3 is restricted on the T-shaped bolt 1 by the nut 2 , the U-shaped card 3 and the T-bolt 1 slide relatively, and the contact surface of the U-shaped card 3 and the fastener is provided with a matching convex surface 4 .

[0010] The fasteners fixed with this T-shaped bolt 1 need to meet the requirements that there are card edges on both sides of the bayonet of the clip. Through the limit of the card edge, even if the T-bolt is not fastened, the T-bolt is firmly restricted in the bayonet, which prevents the T-bolt from falling out, realizes one-time installation, and makes the installation safer. The threaded end of t...

Abstract

The invention relates to a building fastener, in particular to a building fastener bolt. The building fastener bolt comprises a T-shaped bolt body, a U-shaped clamp and a nut connected with the T-shaped bolt body. The U-shaped clamp is limited on the T-shaped bolt body through the nut. The U-shaped clamp can slide relative to the T-shaped bolt body. Matched protruding faces are formed on the contact faces of the U-shaped clamp and the fastener. By the fastener, connection is fast and safe.

Description

technical field [0001] The invention relates to a construction fastener, in particular to a construction fastener bolt. Background technique [0002] In the construction of construction projects, fasteners are necessary and important facilities. They are mainly used for the connection between steel pipes and steel pipes, and the usage is very large. When fastening the fastener, the steel pipe is clamped in the fastener, the bolt is clamped into the bayonet of the fastener, and then the nut is turned until the two ends of the fastener are fastened; but during the connection process, due to the bolt If the bayonet is not fastened, the bolt will easily slip out of the bayonet, which will not only cause repeated snapping, but may even cause the steel pipe to slip out. Contents of the invention [0003] The purpose of the present invention is to provide a simple and firm construction fastener bolt. [0004] In order to achieve the above object, the present invention provides ...
