1. Hang the safety net from the second floor and set it up every 10 meters (or three floors). The safety net must be intact and reliable.
2. Pulling must be firm. The diameter of the pre-embedded steel mesh wall is not less than 14, and the length of the steel bar is not less than 30d.
3. The elevator shaft protection safety net shall not be dismantled at will. When the elevator is installed with scaffolding, it can be removed every time it reaches the height of the safety net.
4. The scaffolding of the elevator shaft is always erected with steel pipes and fasteners. The vertical and horizontal bars are connected by right angle fasteners, and the fastening torque of the fasteners reaches 4-5kg.m.
5. All the horizontal ends of the scaffolding are tightly supported with the wall surface. The distance between the surrounding horizontal wall and the wall surface is 60cm on the balance weight side and 40 cm on the other three sides. The steel pipe should be added to the wall. The spacing should be no more than 20 cm, and the wall surface of the partition steel bars should be no more than 20 cm.
6, scaffolding column distance is not more than 1.8 meters, the row spacing is 1.8 meters, each row below the floor surface 20 cm plus a row of horizontal rafts, the horizontal spacing is 35cm, full of bamboo rafts, bamboo rafts are always connected with 18# double strands Bundle no less than 4 points and tie the steel pipe firmly.
7. The order of demolition of scaffolding should be carried out from top to bottom. The removed steel pipes and bamboo poles must be properly transported out of the elevator shaft, and littering is prohibited.
8. The facilities in the elevator shaft must be inspected and maintained regularly by scaffolding maintenance personnel to find hidden dangers in time.
9. When installing the safety net and dismantling the facilities in the hoistway, the operator must wear the seat belt, and the hanging point must be safe and reliable.
