Membrane structure parking shed The quality of the project foundation. The project foundation of the membrane structure stand generally refers to the embedded bolts of the steel structure. The embedded bolts are the first step of the whole project construction. The formwork shall be fabricated and installed according to the drawings first. Use two installation formworks and reinforcements to position the embedded bolts on the main reinforcement and formwork of the column, so as to ensure that the embedded bolts will not be displaced by the civil pouring concrete, so that the distance and height between each group of bolts are within the controllable allowable error range.

At the same time, the membrane structure parking shed needs to pay attention to the protection of bolt threads to avoid damage during concrete pouring. After the completion of the civil works, the elevation and axis of the anchor bolts should be rechecked with a theodolite and a level gauge. The quality of the membrane structure stand steel production and the steel structure raw materials of the membrane structure stand need to be produced in the factory, The processing quality of steel in the factory is crucial to the on-site installation and the overall safety and stability of the membrane structure stand.

In the process of steel processing for membrane structure parking shed, the quality control of key processes should be carried out according to the process flow, such as the process control of steel connectors and steel components, and the use of processing equipment. The welding quality of steel for steel structure and the welding of steel are important links in the process of steel structure manufacturing and installation, but this is also where problems are likely to occur, For example, the slag inclusion, porosity and other defects of the weld will affect the stability and safety of the membrane structure stand. Therefore, before welding, the welding materials and equipment should be inspected. At the same time, there should be no cracks on the weld surface. The weld should be subject to nondestructive testing as required. The weld at the same part should not be repaired more than twice.
