Safety ropes must be hung under the height of the homework; when the height of the building exceeds 4m, it is necessary to set up a safety rope that gradually rises with the wall. Currently, a strong safety net is set every 4m; on the outer frame, the bridge frame, A safety net must be set up at the bottom of the hole. The erection of the safety net should be low and high, and the local difference is usually 5Ocm; the support rod is not broken or bent; the inner edge of the net is less than 15cm; the lowest point of the net is more than 3m. . For the support of the safety net erection, the diameter of the small head of the wooden pole shall not be less than 7cm, the diameter of the small head of the bamboo pole shall not be less than 8cm, and the spacing of the poles shall not be greater than 4m.
Before use, you should check whether the safety net can be corrupted or destroyed. In the construction, it is necessary to ensure that the safety net is in good condition, support fairness, and is evenly stressed. There must be no debris in the net. The lap joints should be close and reliable, and there must be no loopholes. The safety nets that are erected must not be demolished or destroyed during the construction period, and must be removed when there is no high school work. When the safety net that has been erected is temporarily removed due to the construction demand, the construction unit must take care of it and accept the unit to approve the removal. Construction must be completed immediately after the construction unit is required to be rectified according to the rules, and can only be used after passing through the erection unit.
Every time you clean up the debris in the net, when you perform welding homework on the top of the net, you should accept the useful steps to avoid the welding sparks falling on the net; there should be no acid and alkali smoke that is tight around the net.
Safety ropes must be checked every time they are used, and there are records of tracking and use. Safety nets that do not meet the requirements should be disposed of in real time. When the safety net is not used, it must be properly stored and kept to avoid moisture and mildew. The nameplate of the new product must be inspected before use: the first look is the flat net, the old net, the net war network must be severely left, the net does not allow the use of the flat net; when the net is set up, the bottom of the tether Must be strong. The production certificate of the manufacturer; the factory and the certificate of the product, if the old network should be tested before use, and there is an experimental report, the old network of the experiment can be used.
