Introduction to Scaffolding
Scaffolding is a working platform set up to ensure the smooth progress of various construction processes. According to the erection position, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo s...Read more -
Scaffolding body and building structure binding requirements
(1) Structural form: The tie point is fixed on the embedded steel pipe with steel pipe fasteners, and the cantilevered horizontal steel beam is tied with the building with steel wire ropes. The tie rod must be set on the pole while pulling the inner and outer poles. The tie rods are arranged hori...Read more -

External scaffolding calculation method
(1) The height of the scaffolding on the exterior wall of the building is calculated from the design of the outdoor floor to the cornice (or the top of the parapet); the amount of work shall be based on the length of the outer edge of the exterior wall (wall stacks with a protruding wall width gr...Read more -
Cause Analysis of Scaffolding Deformation Accidents
1. When the scaffold is unloaded or the tensioning system is partially damaged, immediately repair it according to the unloading method formulated in the original plan, and correct the deformed parts and rods. If the deformation of the scaffold is corrected, set up a 5t reverse chain in each bay ...Read more -
The overall stability of scaffolding
Scaffolding may have two types of instability: global instability and local instability. 1. Overall instability When the whole is unstable, the scaffold presents a horizontal frame composed of inner and outer vertical rods and horizontal rods. The large wave bulges along the direction of the vert...Read more -
Specification for setting up steel scaffolding
1. When using a steel scaffolding board, one end of the small crossbar of the single row scaffold is fixed on the vertical bar (large crossbar) with a right-angle fastener, and the other end is inserted into the wall, and the insertion length is not less than 180mm. 2. The scaffolding on the work...Read more -
