The components include the following parts:
1. Scaffolding tube
Scaffold steel pipes should be welded steel pipes with an outer diameter of 48 mm and a wall thickness of 3.5 mm, or welded steel pipes with an outer diameter of 51 mm and a wall thickness of 3.1 mm. The maximum length of steel pipes used for horizontal horizontal rods should not be greater than 2m; other rods should not be greater than 6.5m, and the maximum mass of each steel pipe should not exceed 25kg, so as to be suitable for manual handling.
2. Coupler
Fastener-type steel tube scaffolding should be made of forged cast iron fasteners. There are three basic forms: right-angle fasteners used for the connection between vertical cross bars; rotating fasteners used for the connection between parallel or oblique bars and Butt fasteners for butt connection of rods.
3. Scaffolding plank
The scaffolding board can be made of steel, wood, bamboo and other materials, and the mass of each piece should not be greater than 30kg. Stamped steel scaffold board is a commonly used scaffold board, which is generally made of 2 mm thick steel plate, with a length of 2 to 4 m and a width of 250 mm. The surface should have anti-skid measures. The wooden scaffolding board can be made of fir board or pine wood with a thickness of not less than 50 mm, with a length of 3~4m and a width of 200-250 mm. Both ends should be equipped with two galvanized steel wire hoops to prevent damage to the ends of the wooden scaffolding board. Bamboo scaffolding board is made of bamboo skewer board and bamboo slatted board by using moso bamboo or nan bamboo.
4. Side bracket
The connecting wall piece connects the vertical pole and the main structure together, and can be made up of rigid connecting wall pieces with steel pipes, fasteners or pre-embedded pieces, or flexible connecting wall pieces with steel bars as tie bars.
5. Jack base
There are two types of bases: plug-in type and jacket type. The outer diameter D1 of the plug-in type is 2 mm smaller than the inner diameter of the pole, and the inner diameter D2 of the jacket type is 2 mm larger than the outer diameter of the pole.
