The pole joint adopts the butt joint. The bottom of the scaffold is provided with a continuous horizontal sweeping rod at a distance of no more than 20cm from the bottom of the base. The sweeping rod is fixed on the pole. The poles are staggered with 4m and 6m steel pipes to ensure that the position of the pole joints is staggered. Two adjacent pole joints shall not be placed in the same span and at least 50cm in the height direction.
Considering that the size of most safety net materials in the construction market is 1.8m×6m, and ensuring that the safety net can effectively cover the outer façade of the outer frame, the spacing of the large crossbars is generally 0.9m. The inner row spacing (step) is 1.8m. When erecting a large horizontal bar, every three steps should be leveled with a scaffolding spirit level
to ensure level.
Each crossbar is provided with a small crossbar at the intersection of the horizontal level of the vertical scaffolding spirit level
and the position of the main node is less than 15cm, and is fastened to the longitudinal horizontal pole with a right angle fastener. The pitch of the small crossbar is the same as the longitudinal distance of the vertical pole, and the small horizontal rails of the upper and lower layers are staggered at the vertical pole. In order to ensure the uniform appearance of the façade, the distance between the small crossbar and the edge of the large horizontal bar is 15cm, and the end of the wall extends to 10~15cm away from the structural surface to ensure the installation, reinforcement and demolition of the external wall formwork by the template operator. .
Scissors support a set of six steps and four spans. The angle between the scissors support and the large crossbar is 60°, which is continuously set on the entire length and height of the outer façade of the scaffold. The struts of the scissor struts are lapped and long, and the lap length is not less than 100 cm. At least three rotating fasteners are used for fixing. The distance from the end fastener to the rod end is greater than 10 cm, and all fixed points are not more than 15 cm from the main node.
（5）Connecting wall parts
The connecting wall parts are arranged in a plum-shaped shape and rigidly connected, and are generally buried in two steps and three spans. The wall piece is set from the first horizontal scaffolding spirit level
horizontal rod, and the wall part is as close as possible to the main node, and the distance from the main node is not more than 30cm.
