(3) Scissor support setting requirements
Each group of scissors supports 5-7 roots across the pole; single and double row scaffolds with a height of 24m or less must be set at each end of the outer façade, and the bottom to the top are continuously set with the erection of the scaffold; The double-row frame with a height of 24m or more shall be continuously arranged along the length and height on the outer façade; the scissors struts shall be connected with the vertical rod and the extended horizontal horizontal rod; the length of the scissors struts shall be overlapped.
(4) Horizontal horizontal pole setting requirements
A horizontal horizontal rod must be set at the main node, which is fastened with right angle fasteners and is strictly forbidden to be removed. The horizontal horizontal rods at the non-main node on the working layer should be set at equal intervals according to the needs of the supporting scaffolding board. The maximum spacing should not be greater than the vertical spacing. 1/2 of the distance; when using steel scaffolding, wooden scaffolding, and bamboo scaffolding scaffolding, both ends of the horizontal horizontal rod of the double-row frame should be fixed on the longitudinal horizontal rod by right angle fasteners.
Preparation before dismantling: comprehensively check whether the fastener connection of the scaffolding, the wall part and the supporting system meet the construction requirements; according to the inspection results, the demolition sequence and measures in the construction plan are supplemented and implemented, and approved by the competent department; People carry out the dismantling of safety technology; remove debris and ground obstacles on the scaffolding.
When dismantling, it should be done: the demolition work must be carried out from top to bottom, and it is strictly forbidden to work at the same time; the wall parts must be removed layer by layer with the scaffolding. It is strictly forbidden to remove the whole or multiple layers of the wall parts and then remove the scaffolding. The height difference of the section shall not be more than 2 steps. If more than 2 steps, additional wall reinforcement shall be added. When the scaffold is removed to the height of the last long pole of the lower part, the temporary reinforcement shall be erected at the appropriate position and then removed. When the scaffolding section and the discrete surface are removed, the two ends of the scaffolding that are not removed shall be reinforced with the wall member and the transverse diagonal bracing according to the specifications; the components are strictly prohibited from being thrown to the ground.
