Modular connecting joint of steel structure

Abstract

The invention provides a modular connection joint of a steel structure. The modular connection joint comprises a first joint, a second joint and a connection block, wherein a positioning post is arranged on the end surface of the first joint, a first connecting groove is formed in the face, adjacent to the end face, of the first joint, the end face of the second joint is provided with a positioning hole, and a second connecting groove is formed in the face, adjacent to the end face, of the second joint, the positioning post corresponds to the positioning hole, the first connecting groove corresponds to the second connecting groove in position, and the first connecting groove and the second connecting groove are connected through the connection block. The radial fixation between the first joint and the second joint is achieved through cooperation of the positioning post and the positioning hole, and axial fixation is achieved through the connection block so that the first joint and thesecond joint can bear radial stress and also bear an axial force, a fixing way is simple, large-batch modular production can be achieved, modular assembly can also be achieved, and the assembly efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and in particular relates to a steel structure modular connection joint. Background technique [0002] In building structures, steel structure connection is very common. Most of the existing connection methods are bolted connection and welding. When screwed connection is used, the bolts are prone to loosening during use, which seriously affects the safety of use; During the welding connection, the various parts are connected as a whole, which can ensure the connection strength, but it is a non-detachable connection, which causes a lot of waste of steel structure materials. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and to provide a steel structure modular connection joint. The cooperation between the connecting block and the first connecting head and the second connecting head realizes the...
