High-level scaffolding safety requirements
scaffolding the general trend is toward lightweight, high strength structure, standardization, assembly and function of the direction of development. Material from wood, bamboo development of metal products; erection process will be phased in assembly methods to minimize or without fasteners, bolts and other components; material will also be phased in thin-walled steel, aluminum alloy products. scaffolding as a base for building facilities, widely used in various large and small construction sites, and has played a significant supporting role. And its development process was a long, imperfect from the beginning to the end of a near-perfect step by step, through a very long process.
(1) must be firmly based on high scaffolding, erection of the former is calculated to meet the load requirements, and construction specifications erection, good drainage measures.
(2) must attach great importance to a variety of structural measures: scissors, pull node Dengjun should be required to set up.
(3) the level of closure: from the first step on, every step or two steps, paved or scaffold scaffold board fence, along the length of the laying of scaffold board, the joint should be set aside in a small bar on the overlap, there is strictly prohibited short board. And in the pole and the wall system between the laying of every four steps the end of a long security fence.
(4) vertical closed: from the second step to the fifth step, the outer row of each step required to set the pole in the side of the 1.00m high fence and blocked the protective-like feet, or the establishment of network protection rod (mesh) and the pole anchored ; fifth step above except fortified barricade rod, it should be all set up network security fence or security legislation; in the streets or densely populated areas, should be starting from the second step, all located outside the security fence or network security legislation.
(5) erection of scaffolding on the finished steel, fasteners, such as scaffold board and connection points shall not be arbitrarily removed. Construction, when necessary, must be approved by the site responsible for the consent, and to take effective measures to complete the process immediately after recovery.
(6) scaffolding before use, shall be responsible for site inspection and acceptance of human tissue, acceptance and fill out a single inspection before use. During the construction process should be designed to manage, check and warranty, and regular subsidence observed abnormal reinforcement measures should be taken promptly.
(7) scaffolding removed, should first check the connections with the building and scaffolding on the retention materials, and other debris cleaned from top to bottom, by taking first after the demolition, after demolition of the order before installation, removal The material should be passed down or lifted onto a uniform surface, a step clear. No split by stepping method, non-down throw or push (pull) down method removed.
(8) take the dismantling scaffolding, warning area should be set, and sent people alert. In case of six or more high winds and bad weather, work should stop dismantling scaffolding ride.
