1. Installation conditions:

The steel plate gutter has the following conditions before installation: the steel structure main body (referred to as beams and columns) has been installed and adjusted, and all high-strength bolts have been fully screwed. For the parapet project, the parapet columns and corresponding wall beams have been installed and adjusted. The steel plate gutter has been carried out. Welding machines and welders for welding are in place.

2. Installation:

After inverting the corresponding steel gutter in place according to the design drawings, according to the size and weight of the gutter, use a crane to lift or manually transport it, transport the gutter to the designated installation area, and immediately use electric welding to temporarily remove the gutter connection. After all the gutter material is in place, pull a straight line along the outside of the gutter with a steel wire to adjust both the inner and outer sides of the entire gutter to the same straight line. When adjusting, pay attention to make the gap at the joint of the gutter small and use Temporarily fix the electric welding, and then use the welding rod with a diameter of 3.2mm to fully weld the bottom horizontal welding seam and the straight welding seams on both sides. Welding quality and control of the welding flow must be paid attention to when welding
