quality of the erection will also affect the use of the scaffolding.

Scaffolding is an indispensable measure for high-altitude operations. It is a visible operation. It not only involves safety during the erection process, but also the quality of the erection will also affect the use of the scaffolding. Safe passage cannot be ignored.

Second, the large bar
1) The large cross bar is set under the small cross bar, and it is fastened with a right-angle fastener to the inside of the post.
2) The large crossbars are connected by butt-fasteners. The butt joints are staggered. They are not set in the same span, and the horizontal distance between adjacent joints is not less than 500mm. Avoid being set in the middle of the longitudinal horizontal bar.
3) The large cross bar should be arranged on the inner side between the vertical bars and the adjacent walking frames should be staggered. The length of the large cross bar members should be 4.5m and 6m.
4) The horizontal deviation of the large crossbars in the same row shall not be greater than 1/300, and the vertical height difference of the four sides of the large crossbars shall not exceed 50mm. Three large crossbars are required as protective railings on the working surface layer, which are 1500mm, 1000mm, and 500mm higher than the scaffolding boards, and footboards are set on the working layer.
