Scaffolding system before erection, the basis of the plane to check, take the way to draw the line to ensure that the scaffolding system under the same level of care to ensure that the scaffolding system of uniform force, Scaffolding System the construction of the connection point to ensure that the close, The situation arises.
Under the side of the square wood
In order to prevent the concentrated load of the leg to pass the bedding layer of concrete cracking, on the top of the square wood, Scaffolding System square wood thickness of not less than 5cm, width of not less than 20cm.
Under the adjustable pole base, the screw and nut kneading length of not less than 5 buckle, and the extension should not exceed the length of 30CM, insert the length of the pole shall not be less than 30CM. Scaffolding System Pole base and square wood, square wood and hardened between the ground should be close, no void and loose.
According to the design of the layout of the pole, with a load-bearing pole must be docked, not allowed to lap. Only the upper and lower pedestrians and auxiliary construction for the construction of the scaffolding system in addition to the top of the top step can be used to lap, the rest of the layers of the joints must be used docking fastener docking. The butt fasteners on the pole should be arranged in a staggered manner. Scaffolding System The joints of the two adjacent levers should not be set in the synchronizer. The distance between the two adjacent joints of the two connecting rods in the height direction should not be less than 50cm. To the main node of the distance should not be greater than 1/3 of the step.
Each erected a layer of pole, after passing the inspection, the bar and the bar erection. According to the design requirements to set up crossbar and vertical bar, bar and vertical must be level. Scaffolding System If it is fastener scaffolding system vertical, horizontal bar and pole of each node should be fastened with fasteners, non-buckle or buckle is not allowed to appear.
The main node must be set at a horizontal horizontal bar, with fast nuts fastened and is strictly prohibited to remove. The center distance of the two right angle fasteners at the main node shall not be greater than 150 mm.
Fixed with a right angle fastener on the pole, not more than 20cm from the base. Horizontal sweeping rods should also be fastened at right angles to the pole on the underside of the longitudinal sweep bar. Scaffolding System When the base of the pole is not at the same height, it is necessary to extend the height of the longitudinal sweeping pole to the lower side. The height difference should not be greater than 1m. The distance from the pole axis above the slope to the slope should not be Less than 50cm.
Scaffolding system description
Applicable to construction, decoration and other projects in the scaffolding system engineering.
(1) scaffolding system erection, removal and use of components must meet the scaffolding system-related standards and the "project location related to the construction project safety protection standards," the provisions of the shelves should be prepared, acceptance, etc. should be consistent with the "more dangerous sub-sub-items Project safety management approach "(built quality  87) requirements.
(2) Do not use wood, bamboo scaffolding system and steel wood, steel bamboo scaffolding system.
Scaffolding system foundation must be flattened compaction, Scaffolding System on the basis of the length of the scaffolding system should be set along the length of the pad, the pad material can be used wood scaffolding or channel, scaffolding system should be taken to organize drainage, surrounded by drains.
Scaffolding system construction operation surface must be full of scaffolding board, from the wall shall not be greater than 20cm, no gap and probe plate, fly springboard; Scaffolding System operating surface outside should be set up a body railings and a 20cm high foot plate; When the distance is greater than 150mm must be closed; scaffolding system construction layer below the operating surface clearance distance of more than 3.0m, you must set a level of safety net, double row of the mouth and the structure between the external walls can not be protected when the laying of scaffolding; The frame must be enclosed by a dense safety net along the inside of the outer frame, and the safety net must be securely connected, tightly closed and fixed to the frame.
