Matters needing attention during steel structure construction

The whole process of steel structure construction needs to pay attention to those matters, it may be because of neglect and cause a lot of unnecessary economic losses and safety risks. The part of the high-strength bolt should be effective, and the engineering construction area of the twister and torque wrench should be fully considered. It should not be used in the installation. This is because the area is too small, the twister and torque wrench can not be in place, causing the high-strength bolt plum head can not be twisted off or the high-strength bolt can not be tightened. Previously encountered design scheme even bolt parts are not given. In the whole process of electric welding welding also need to pay special attention to their safety and reliability, such as before and after the facilities to be careful, power distribution to be careful.

Steel structure if there is a maintenance wall, must advance with the construction enterprise and construction engineering construction enterprise project docking, it is because it involves civil engineering structure and two of this phenomenon, this is because of the wall is likely to make civil engineering is not smooth, can the structure of the roof drainage and is unlikely to do big and small, the result is the clearance between the wall and structure big and small, The roof drainage of the structure and wall can not be handled correctly, so that the construction enterprise has the heart to prepare in advance.

Before installation and use, the construction enterprise shall check the product qualification certificate, design scheme materials and pre-assembly records of prefabricated components, and check the appearance and size of prefabricated components with inspection records. When the deformation copy and defect of the structure exceed the allowable error, it should be handled correctly. Before the installation of the steel structure, the detailed accurate measurement and correction of the processing technology should be compiled 2113. The electric welding of the carbon steel plate should be done before the installation and use of the electric welding to simulate the processing technology experiment of the product structure, and the corresponding engineering construction technology should be programmed. After the structure lifting is in place, the standard control points of the design scheme such as the axis of the prefabricated component and the design elevation shall be measured accurately and marked. The quality of the lifting butt weld shall be inspected before 4102 lines. Installation and use of temporary support points and steel wave cables in order to ensure the safety and stability of the structure in the whole process of construction. During the installation of the steel structure, the construction enterprise shall submit an application for the design elevation, outline dimension, 1653 electric welding and painting process of each prefabricated component after lifting to the project supervisor for project acceptance.
