For different types of scaffolding, different requirements need to be met during installation. If it is an ordinary conventional scaffolding, except for the top top step, the vertical joints of the vertical poles must be connected with the docking fasteners.

 

In addition, the joints of two adjacent vertical poles of a scaffold shall not be set within the same step. The distance between two spaced joints of a vertical pole separated by a vertical joint in the synchronous direction shall not be less than 500 mm: the distance from the center of each joint to the main node shall not be greater than One-third of the step. If the top-level top pole adopts a lap joint length, the overlap length shall not be less than 1000mm, and shall be fixed with not less than 2 rotary fasteners, and the distance from the edge of the end fastener cover to the rod end shall not be less than 10mm.

 

Not only that, the scaffold must be equipped with vertical and horizontal sweeping rods, and the vertical and horizontal sweeping rods should be fixed on the uprights not more than 200mm away from the base skin by means of right angle fasteners. When the foundation of the pole is not on the same level, the vertical sweeping pole at the height must be extended to a low position to extend the two spans and the pole. The height difference should not exceed 1m.

 

For a double-row fastener steel pipe scaffold with a height of 24m or more, a rigid wall member must be used to reliably connect the building; for a single and double-row scaffold with a height less than 24m, a rigid wall member can be used to reliably connect the building. It is also possible to use wall-to-wall connections with tie bars and roof braces, but use flexible tie-walls with only reinforcements are strictly forbidden.

 

There are also a single-shaped, open-ended double-row steel pipe fastener scaffolds, both of which must have lateral bracing. For closed scaffolds with a height above 24m, lateral joists should be provided in addition to the corners, and one should be set at every 6 crosses in the middle. Lateral braces should be arranged in a zigzag pattern from the bottom to the top.

 

With a reliable and stable structure, scaffolding can be widely used in the field of quality supervision, teaching and scientific research, iron and steel metallurgy, automotive, building materials and other test areas. And with a wide range of attachments for the mechanical properties of profiles and components test.
