　　Deformation caused by the collision in the transport of components, generally showing dead bend
Bending deformation of components, the use of mechanical rectification. With the help of a jack or other tool to correct or assist the oxyacetylene flame.

After the erection of the steel beam member, the full length distortion exceeds the allowable value, resulting in the poor installation quality of the steel beam
The assembled components should be provided with a working table, and the bottom surface of the component can be leveled to prevent warping. The working table should be set at each level, and the welding deformation should be avoided. Especially in the last assembly segment or stairway, to adjust the positioning in the deformation after welding, the attention node should comply with the design size, otherwise easily lead to distortion component.
When the component is deformed during transportation, there is dead or slow bend, which can not be installed
When the component is made, the measures to reduce the welding deformation are adopted.
Bolt equipment surface does not meet the requirements, resulting in poor installation of bolts, or the degree of bolt tightening does not meet the design requirements
High strength bolt surface rust, oil and bolt hole defects, should be cleaned up one by one. Before use must be anti rust treatment, so that the assembly bolts, shall not be used in the formal assembly. The bolts shall be kept and distributed by the person.
