1. Weld a u-shaped rod on the bottom surface of the upper flange plate of the h-shaped steel beam, one end of the u-shaped rod is close to the connecting side of the h-shaped steel beam, and the sliding sleeve is inserted into the u-shaped rod and slides along the u-shaped rod;
2. Weld the sliding sleeve on the top of the splint and the sliding sleeve is on one side of the splint, and use temporary bolts to connect the splint and the h-beam web so that the splint can be reliably fixed on the side of the h-beam web;
3. Three, hoist the h-shaped steel beam, hoist the h-shaped steel beam connecting the splint to one end of the h-shaped steel beam that has been in place and connect it, and set a card plate between the upper flange plates of the butt ends of the two h-shaped steel beams. Temporary fixation to avoid dislocation of the butt ends of the two H-shaped steel beams;
4. Remove the temporary bolts of the plywood and the h-shaped steel beam web, push the plywood to the side of the in-place h-shaped steel beam through the sliding sleeve and the u-shaped rod, and make the installation holes of the plywood match the two h-shaped steel beams. The installation holes of the webs of the steel beams are aligned, and the high-strength bolts are screwed to the installation holes of the plywood and the webs of the two h-shaped steel beams, and the construction of the high-strength bolts is completed according to the initial setting and final screwing specifications.
