Abstract

The invention discloses a fastening piece for a unilateral bolt. The fastening piece comprises the bolt, a nut, a gasket, a plate and a long and round tip; one end of the bolt is fixedly connected with the long and round tip; the other end of the bolt is in threaded connection with the nut; the gasket is movably arranged on the bolt between the long and round tip and the nut; a hexagonal prism is integrally molded at the other end of the bolt; a strip-shaped groove is formed in one end of the prism and is parallel with the long axis of the long and round tip; and the hexagonal cross section of the hexagonal prism is internally connected with the round cross section of the bolt. The piece is more convenient to mount and reliable in fastening effect, and fastening can be completed without special tools. Besides, all that is required for the bolt fastening operation is unilateral operation during use. Bolt mounting under certain special working conditions is realized. The piece can be applied to actual construction and has the good use effect.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and mechanical assembly, in particular to a single-sided bolt fastener. Background technique [0002] At present, in the field of civil engineering and mechanical installation, there is a large demand for the installation of connection and fastening of structural parts. As far as bolts are commonly used at present, when performing connection and fastening operations on components, workers need to perform installation operations on both sides of the components at the same time. This connection and fastening method has simple structure, convenient operation, and good load bearing. However, it is only applicable to open section members. In some special occasions, such as fastening closed section members or members that are inconvenient to work on the other side, this commonly used bolt and nut connection fastening method cannot be used. Therefore, it is necessary to develop a unilateral b...
