When the scaffolding poles are not on the cantilevered steel beams, the connecting beams are made of 12.6# channel steel. The embedded parts are embedded in the structure in advance. The I-beam is processed, and a connecting steel plate with a thickness of 10mm, a length of 200mm and a width of 180mm is welded at one end (and a hole is made in the steel plate, a circular hole with a diameter of 22mm on one side and an oval hole on the other side, on the position where the pole is placed. Weld the corresponding number of 150mm long, Φ25 short steel bars to place the vertical poles, and the structural strength report of the beam and shear wall can reach more than 75% of the design before the cantilever beam can be installed, and the processed I-beam and pre-buried in Align the embedded parts in the structure, and then use two M20 high-strength bolts to pass through the gasket and the connecting steel plate and then insert the steel pipe 7 into the embedded parts. The inner ends are fixed with nuts, and the underside of the I-beam is supported by scaffolding. In order to ensure the stability and safety of the structure, after the structural strength fully reaches the design strength, remove the scaffolding that supports the lower side. When the length of the I-beam at the cantilever end is less than 1.5m, set up a diagonal pull, when the length is greater than or equal to 1.5m To ensure the stability of the structure, two oblique pulls are set up at any time to ensure the stability of the structure. After erecting the poles, set up horizontal poles and small horizontal poles according to the step distance. The horizontal poles are connected with the vertical poles.
