Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel bar truss processing, in particular to a steel bar truss welding point clamping anti-welding opening device. BACKGROUND

[0002] Steel bar truss welding refers to assembling and welding upper chord steel bars, lower chord steel bars and web steel bars, and welding and fixing support vertical steel bars and support horizontal steel bars at both ends to form an integrated steel bar truss.

[0003] When welding a steel bar truss, the shorter the gap between the lower chord steel bars, the higher the welding point height of the upper chord steel bars, and vice versa. At this time, the angle of the web steel bars connecting the lower chord steel bars and the upper chord steel bars will change, and the welding point will also change. The positioning of the web steel bars is the basis for ensuring the welding quality of the steel bar truss. When the existing equipment does not comply with the conventional welding point of the steel bar truss and is adjusted, it cannot guarantee that the two welding points of the web steel bars fully fit the adjusted upper chord steel bars and lower chord steel bars, so it is easy to cause the end points of the welding points to separate or the welding points to be too rough, which cannot meet the welding quality, and causes safety hazards in the subsequent use of the steel bar truss.

The first limiting track and the second limiting track are synchronously unfolded. The positioning column at the positioning sliding block installed on the first limiting track and the second limiting track unfolds the web steel bar. The top end of the web steel bar is clamped on the surface of the upper chord steel bar, and the middle part of the web steel bar is clamped on the surface of the lower chord steel bar, so as to reduce the gap between the web steel bar and the upper chord steel bar and the lower chord steel bar, avoid the welding point from being opened during welding, and increase the welding strength of the steel truss.
