(1) When ripping, the operator must hang up and fasten the safety belt.
(2) Before shuttering, relevant scaffolding must be set up (see scaffolding scheme and related scheme of this project and related safety operation procedures, etc.). ).
(3) The scaffold shall not be dismantled before the wall formwork is dismantled, and the crane shall be used to cooperate with the rigger when dismantling; Before dismantling the roof formwork, delimit safe areas and safe passages, close unsafe passages with steel pipes and safety nets, and hang safety signs of "No Passage". Operators are not allowed to operate in this area, but must operate on the operating frame covered with springboard.
(4) Before pouring concrete, it is necessary to check whether the support is reliable and whether the fasteners are loose. When pouring concrete, a formwork team must be set up, and a designated person should guard the formwork, check whether the support is deformed or loose at any time, and organize recovery in time. Always check whether the bolts at the joint of formwork hook, diagonal brace and platform are loose, and organize to deal with the problems in time when found.
(5) Woodworking machinery must strictly use reverse switch and special switch box, the primary line shall not exceed 3m, and the shell shall be connected to the protective zero line with good insulation. The chainsaw and planer must be connected with a leakage protector, and the saw blade must not be cracked (check before use and check at any time during use); Moreover, the chainsaw must have a belt guard, a saw blade guard, a distributor and a hand guard. When using woodworking multi-purpose machinery, it is forbidden to use chainsaw and planer at the same time; It is forbidden to wear gloves when using woodworking machinery; It is forbidden to use chainsaws for wood whose length is less than 50 cm or whose thickness is greater than the radius of the saw blade; Two people cooperate with each other when operating, and shall not be pulled hard; When the machine stops, turn off the power and lock it.
(6) When lifting the formwork with tower crane, it must be commanded by the rigger and strictly abide by the relevant safety operation procedures. Before the template is installed in place, it needs to be pulled by cable to prevent the template from rotating badly and hurting people; Vertical lifting must be carried out with more than two lifting points, and the lifting must be carried out with clasps. Lifting two templates at a time is not allowed.
(7) When the steel formwork is stacked, the formwork shall be inclined downward by 30, and the formwork shall not be stacked on the construction layer to prevent the formwork from overturning under the action of wind load.
(8) The yard of large formwork shall be hardened, leveled and fenced, and the formwork of Yin and Yang angles shall be placed with small fenced. After installation in place, protective measures should be taken to prevent electric shock. Large formwork should be connected in series and connected with lightning protection network to prevent electric leakage from hurting people.
(9) During the formwork construction of elevator room, a safety protection platform must be built step by step. Because the lateral force of concrete is influenced by both temperature and pouring speed, the pouring speed of concrete can be appropriately increased when the construction temperature is high in summer, and it should be appropriately reduced when the construction temperature is low in autumn and winter. When T= 15℃, the concrete pouring speed is not more than 2m3/h 。
(10) environmental protection and civilized construction
From 22: 00 to 6: 00 in the evening, template processing and other template operations should be stopped on site. On-site template processing garbage should be cleaned up in time and put into the designated garbage station. Do it after work. The whole template stacking site and construction site should be orderly, clean, pollution-free, low noise, low dust and low energy consumption.
