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 -
Scissor braces and lateral diagonal braces in scaffolding
1. Double-row scaffolds should be provided with scissor braces and transverse diagonal braces, and single-row scaffolds should be provided with scissor braces. 2. The setting of single and double-row scaffolding scissor braces shall meet the following requirements: (1) The number of spanning pole...Read more -
Precautions when erecting scaffolding
(1) Before fixing the bottom end of the pole, the wire should be suspended to ensure that the pole is vertical. (2) After correcting the verticality of the vertical bar and the horizontality of the large horizontal bar to make it meet the requirements, tighten the fastener bolts to form the initi...Read more -
Standard practice for overhanging scaffolding
1. A special construction plan should be prepared and approved, and experts should be organized to demonstrate the plan for the construction of more than 20m in sections; 2. The cantilever beam of the cantilevered scaffold must be made of I-beam above 16#, the anchoring end of the cantilever beam...Read more -
The butt joint and lap joint of scaffolding poles shall meet the following requirements
(1) When the scaffolding pole adopts butt joint length, the docking fasteners of the scaffolding pole should be arranged in a staggered manner, and the joints of two adjacent scaffolding poles should not be set in synchronization. The staggering distance of the joints in the height direction shou...Read more -
Scaffolding Coupler Installation Requirements
(1) The specification of the coupler must be the same as the outer diameter of the steel pipe. (2) The tightening torque of the couplers should be 40-50N.m, and the maximum should not exceed 60N.m. It must be ensured that each coupler meets the requirements. (3) The distance between the center po...Read more -
Attached Lifting Scaffolding
The attached lifting scaffold refers to an external scaffold with anti-overturning and anti-fall devices (also known as a “climbing frame”) that is erected at a certain height and attached to the engineering structure. ). The attached lifting scaffold is mainly composed of the attache...Read more
