The erection and demolition of scaffolding can only be carried out after the erection and demolition of scaffolding workers (construction ascending and erecting operators) have been trained and examined in the safety technology of special operations and high operations, and have obtained the operation certificate of special operations and passed the physical examination.
The erection of steel scaffolding must be carried out according to the specification, that is: horizontal and vertical, firmly connected, the foot is really, layers of knots, the support is straight, smooth and flat, complete and firm facilities.
The erection workers must be strictly in accordance with the requirements of the special tower crane construction scheme and operation rules, in the erection to correctly wear and use labor protection supplies.
The scaffold shall not be steel, bamboo mixed, the main force rod, such as vertical rod, large cross bar, small cross bar and scissors support, etc., in the same building facade must use the same material.
The construction of steel pipes and fasteners must meet national standards, prohibit the use of serious rust, bending deformation or crack steel pipes, brittle, deformed, sliding fasteners are also prohibited.
The inner pole of the scaffold and the outer wall shall be protected according to the regulations. The scaffold ramp should have an independent support system, the corner rest platform should not be less than 2 square meters, the slope of the ramp should not be greater than l: 3, and the spacing of the anti-slip strip should not be greater than 30 cm.
The foot of the steel pipe scaffolding pole should be placed vertically and steadily on the concrete pad or the concrete hardened foundation, and the longitudinal and horizontal sweeping bar should be set.
8, the feet at both ends of the frame, the corner and the outside of the scissors support must be connected in place, the structure and number of pull nodes meet the requirements.
The vertical pole of the tower crane should be equidistant, the longitudinal distance should not be greater than 1.8 water, and the scaffold should not be greater than 20 cm from the wall. If it is larger than 20 cm, isolation measures must be taken.
This is the first one.
This is the last one.
