Precautions for space frame construction

 All kinds of steel pipe scaffolders set up for the construction of the grid must be prepared special safety construction organization design and special design calculation, in the operation should comply with the relevant provisions.

When a mobile scaffold operation platform is set up, the scaffold pole should be welded on the channel steel, and the longitudinal and transverse sweeping poles must be set at 200mm away from the channel steel surface. Scaffolding ramp and rest platform, working layer surrounding protection and foot and hand board laying shall comply with relevant regulations.

Mobile scaffolding must comply with the provisions of special safety construction organization design when towing.

Each time the scaffold is dragged, there should be special command, special observation, first try to drag 1 ~ 2m, check the deformation of the shelf, and confirm that there is no deformation before it can be formally dragged. After towing and positioning, the deformation and idleness of the scaffold should be comprehensively checked to confirm that there is no deformation before it can be used.

Steel bolt balls, rods and other components of the space frame should be hoisted to the scaffold platform in batches. It shall not be piled on the shelf platform in large quantities at one time, and it shall be installed and transported with it.

The operator on the scaffold platform should be minimized, and no one should be concentrated in a span of the scaffold during the operation.

The operator who installs the steel bolt ball and rod on the grid body should use the safety belt, the safety belt should be hung on the solid structure, and the installer must be equipped with a tool bag and tool hooks.

When the grid is dragged or jacked, all equipment should be fixed firmly, the operating position should be set up a firm operating platform, and should be set up walking handrails or protective railings. No one should stay on the frame while towing or jacking.
