4. Quality defect of adjustable U-shaped top bracket
The collapsed bracket was found that the U-shaped top bracket hand plate nuts were broken and lost. The hand plate nut passed the load on the top bracket to the casing through the end surface. The unqualified nuts directly led to the failure of the top bracket and the loss of bearing capacity. The load was directly distributed to the adjacent vertical poles. Therefore, the local load was increased, which exceeded the design load value of the bracket.
In addition, there are also some problems in construction technology, such as defects in the design of support system, excessive cantilever at the top of the support and problems in the arrangement of vertical inclined rods.
It is these factors that led to the accident. Therefore, in order to ensure the safety of construction, it is very important to control the quality of each batch of scaffolding entering the site. Besides, it is also crucial to improve the construction technology level, ensure the accuracy of each plan, do well in site management, strictly compliance with the construction rules and requirements and eliminate illegal operations.
How to control the quality of scaffolding?
The most critical point is to refuse the temptation of ultra-low price, refuse to purchase "three-no" products and cooperate with large-scale, well-known and powerful manufacturers as far as possible. Before purchasing, carry out the corresponding factory inspection. After purchasing, pay attention to inspection; ensure that the quality of each batch of scaffolding entering the site is in line with the requirements. Only in this way can reduce the occurrence of scaffolding collapse caused by quality problems.
