1, scaffolding components used in pitched and must meet the national specification. 48-2, steel tube scaffold application diameter - 3-51 mm, wall thickness - 3. 5 mm, no serious rust, bending, flattening or crack of steel pipe. Wooden scaffold application capitulum effective not less than 8 cm in diam. , no rot, fracture, dry section of fir pole, hand bar should not gangmu mashups. Structure of the scaffold pole spacing shall not be greater than 1. 5 meters, longitudinal rod ( The ledger) Spacing shall not be greater than 1. 2 meters, lateral horizontal bar ( Small bar) Spacing shall not be greater than 1 m. Decorate the scaffold pole spacing shall not be greater than 1. 5 meters. Longitudinal bars ( The ledger) Spacing shall not be greater than 1. 8 meters, transverse horizontal bar ( Small bar) Spacing shall not be greater than 1. 5 meters. The construction site fir pole pitched bearing scaffold is strictly prohibited. 3, scaffolding foundation must be solid, smooth drainage measures, meet the requirements of the frame body pitched, ensure no subsidence, not water. The frame must be pitched on the base ( ) Or long on scaffolding. 4, scaffolding construction operating surface must be put with scaffolding plank, away from the wall shall not be more than 20 centimeters, can not have gaps and probe plate, fly the springboard. Operating side lateral should set a protective railings and a block baseboard 18 centimeters high. Scaffold construction layer below the operating side clearance distance more than 3 m, you must set up a level of safety net, double bent in the mouth and structure can't protection level network are laid between exterior wall planks. Frame body must be closed with dense mesh nets along the inside of an outer layer, between safety net must connect firmly, closed tight, and with a fixed frame. 5, scaffolding must according to the floor and firm structure to pull, pull contact vertical distance shall not be more than 4 meters, the horizontal distance shall not exceed six meters. Meet rigid material must be used. More than 20 meters tall shelves should be unloading measures. Continuous bracing (6, scaffolding must be set Cross cover) Ensure the structure deformation, the width shall not exceed 7 root poling, diagonal and horizontal Angle should be 45 60 degrees. 7, special scaffolding and height in more than 20 meters tall scaffolding must have a design scheme, and acceptance formalities. 8, used in the structure and outer bearing scaffold, when using the load shall not exceed 2646 Newton per square meter ( 270 kg/m2) 。 Decorate with, external scaffolding using load shall not exceed 1960 Newton per square meter ( 200 kg/m2) 。 9, projects under construction ( Including the scaffold with) , between the edge of the outside of the edge of an electric overhead lines and should keep a safe distance in accordance with the specification. Special circumstances, effective and reliable protective measures must be taken. Convenient of pitched should use non conductive material, its basic stud for 30 - buried depth 50 centimeters, the overall convenient frame is reliable to top pull measures, ensure that the frame body. 10, the pedestrian. Width is not less than 1 meter, that the slope of the chute is not greater than 1:3; Material handling. The width is not less than 1. 5 meters, the slope is not greater than 1:6 ramps. Bend should set up the platform, in accordance with the requirements set in the border guard protective railings and baseboard, prevent slippery spacing is not more than 30 cm.
