Installation steps of the lower chord of the flat steel space frame structure

 1. Familiarize with the drawings before installation, recheck the size and quantity of each component to be installed, and place each component in the order of installation to facilitate the installation of the steel space frame structure.

2. Before installation, check the quality of the threaded fasteners, clean the screw holes and threaded fasteners, and screw them in after they are clean. The high-strength bolts should be tightened in place to ensure that the downward deflection of the entire space frame structure is not affected.

3. According to the numbered positions of the rods and balls on the drawing, install the lower chord balls and rods in the first span to form a longitudinal plane grid, and tighten the high-strength bolts.

4. After installing the support in the first span, align the axis and centerline of the column top. Use a level to correct the elevation if there are errors.

5. Arrange the temporary fulcrums according to the required elevation of the bottom chord to ensure the elevation position of the bottom string.

The temporary fulcrum can be made of on-site scaffold steel pipes, so that the lower chord grid of the first span can pass through the temporary fulcrum.
