External scaffolding floor height is much greater than the vertical height of the joint wall, how to carry out the joint wall pieces

1, the location and quantity of the joint wall shall be determined according to the special construction plan, usually it can be arranged as three steps and three spans, two steps and three spans and two steps and two spans, etc., and the general area covered by each joint wall shall be 20~40 square meters.

2, the arrangement of wall pieces should be close to the main node set, the distance from the main node should not be more than 300mm; should be the first step from the bottom of the longitudinal horizontal bar set up, when the setup is difficult, other reliable measures should be used to fix; should be prioritized using a diamond-shaped arrangement, or square, rectangular arrangement.

3, open type scaffolding must be set up at both ends of the connecting wall, the vertical distance between the connecting wall should not be greater than the height of the building, and should not be greater than 4m.

4, the connecting wall in the connecting wall of the connecting wall should be set up horizontally, and when it can not be set up horizontally, it should be connected to the scaffolding end of the downward slanting connection.

5, the connecting wall must be constructed to withstand tension and pressure. For double row scaffolding with height more than 24m, it should be connected with building by rigid connecting wall.

6, when the lower part of the scaffolding can not be set up when the wall should take anti-tipping measures. When setting up the throw brace, the throw brace should adopt the long rod, and fixed on the scaffolding with rotating fasteners, and the inclination angle with the ground should be between 45°～60°; the distance from the center of the connection point to the main node should not be more than 300mm, and the throw brace should be dismantled only after setting up the connecting wall parts.

7, the rack height of more than 40m and wind vortex effect, should be used to resist the role of rising tumbling wall measures.
