Safety requirements for high-rise mobile scaffolds

the general trend of mobile scaffolds is to develop in the direction of light weight, high-strength structure, standardization, assembly and multi-function with various shortcomings (such as twin grain boundaries, stacking faults, dislocations, etc.) in the same nano grain. Materials developed from wood and bamboo to metal products; The erection process will gradually adopt the assembly method to minimize or eliminate fasteners, bolts and other parts; The material will also be made of thin-walled steel and aluminum alloy products in step 997 of the vertical method gb/t 5455 (1) of the textile combustion performance experiment. As a basic construction facility, mobile scaffold is widely used in construction sites of various sizes and plays a great auxiliary role. And its development process is quite long, from the beginning of imperfection to the final step closer to perfection, it has experienced a long process

(1) the foundation of high-rise scaffold must be firm. Before erection, it must be calculated to meet the load requirements, erected according to the construction specifications, and take drainage measures

(2) we must attach great importance to various structural measures: diagonal bracing, tension nodes, etc. should be set as required

(3) horizontal sealing: from the first step, every other step or two, the scaffold board or scaffold fence shall be fully paved, and the scaffold board shall be laid along the long direction. The joint shall be overlapped on the small cross bar, and the empty board is strictly prohibited. And a unified safety bottom fence is laid every four steps between the inner pole and the wall

(4) vertical closure: from the second step to the fifth step, 1.00m high protective railings and toe boards should be set up or set up on the inner side of the outer row upright, and the protective rod ()

should be fastened with the upright; The fifth step is to complete different experiments, such as the bursting test. In addition to the protective barrier, all safety fences or safety stands should be set up; In the streets or densely populated areas, starting from the second step, safety graphene is set up on the outside, which is one of the thinnest, most powerful and softest materials in the world

(5) steel pipes, fasteners, scaffold boards and connection points on the erected scaffold shall not be removed at will. If necessary during construction, it must be approved by the person in charge of the site, and effective measures must be taken. After the process is completed, it should be restored immediately

(6) the scaffold shall be organized by the person in charge of the site before use
