Embodiment 1

[0018] A socket type steel stud bolt connection method of this embodiment, the steps are:

[0019] Step 1. Weld the inner connecting steel plate 3 and the outer connecting steel plate 2 at one end of the steel column 1 to form grooves as connectors;

[0020] Step 2. Set proper amount of self-anchor bolt holes 4 around the steel plate and steel column;

[0021] Step 3. During on-site construction, when the upper and lower steel columns 1 need to be docked, insert the steel column 1 without connectors at one end into the groove at the other end with connectors, and pair with the inner connecting steel plate 3 and the outer connecting steel plate 2 The holes are well positioned, and the self-anchor bolts are inserted into the bolt holes from the outside for fastening connection.

[0022] The socket-type steel column bolt connection method of the present invention can achieve precise butt joint of the upper and lower columns, convenient construction, green construction, and reduc...

Abstract

The invention discloses a bolt connecting method of a socket type steel column and belongs to the technical field of building construction. The bolt connecting method comprises the following steps ofS1, welding an inside connecting steel plate and an outside connecting steel plate to one end of the steel column to form a groove as a connecting part; S2, forming a proper amount of self-anchoring bolt holes around the steel plate and the steel column; and S3, in site construction, when the steel columns at the upper and lower ends need to be in abut joint, inserting the steel column without theconnecting piece at one end into another groove in one end with the connecting piece, aligning the hole sites with the inside connecting steel plate and the outside connecting steel plate and inserting self-anchoring bolts into the bolt holes from the outer side for fastening connection. According to the invention, the upper and lower columns are abutted precisely, and the bolt connecting methodis convenient to construct and environment-friendly in construction and reduces adverse effect that an external expanding lug plate occupies a space. The bolt connecting method can overcome the defects that welding construction is low in efficiency, high in labor cost, short in welder, complex in process, and pollutes the environment and the like.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a socket-type steel column bolt connection method. Background technique [0002] The traditional connection between steel columns and steel columns adopts lug plate welding connection, which has disadvantages such as low efficiency, high labor cost, shortage of welders, environmental pollution, and complicated process in welding construction. High-altitude welding has high requirements for environment and safety protection, and wind and fire prevention measures must be controlled in place. Grinding and flaw detection after welding also consume manpower and financial resources. Contents of the invention [0003] 1. Problems to be solved [0004] Aiming at the defects and deficiencies of the existing technology, the present invention provides a socket-type steel column bolt connection method, which can achieve precise docking of the upper and lower columns, conven...
