The assembly of steel structure components is to combine the processed parts or semi-finished components into independent finished products by assembly according to the requirements of the construction drawings.
This assembly method is usually called assembly.
Assembly can be divided into component assembly, assembly, and pre assembly based on the characteristics and degree of assembly of the assembled components.
1.
Component assembly is the combination of the smallest units assembled, which consists of two or more parts assembled into semi-finished structural components according to the requirements of the construction drawing.
2.
Assembly is the assembly of parts or semi-finished products into independent finished components according to the requirements of the construction drawings.
3.
Pre assembly refers to the assembly of two or more related finished components on the factory production site according to their spatial positions according to the construction plan.
The purpose is to visually reflect the assembly nodes of each component and ensure the quality of component installation.
Currently, it has been widely used in the manufacturing of steel structural components connected by high-strength bolts.
2、 General regulations for the assembly of steel structure components: 1.
Before assembly, construction personnel must be familiar with the component construction drawings and relevant technical requirements.
And recheck the quality of the parts to be assembled according to the requirements of the construction drawings.
2.
Due to insufficient size of raw materials or technical requirements, parts that require splicing must generally be completed before assembly.
3.
When using tire molds for assembly, the following regulations must be followed: A.
The selected site must be flat and have sufficient stiffness.
B.
When arranging and assembling the tire mold, it is necessary to consider the pre placed welding shrinkage allowance and other processing allowances based on the characteristics of its steel structure components.
C.
After assembling the first batch of components, a comprehensive inspection must be carried out by the quality inspection department, and the assembly can only continue after passing the qualification approval.
D.
During the assembly process, components must be strictly assembled according to process regulations.
When there are hidden welds, they must be pre welded and inspected to be qualified before being covered.
When complex assembly components are difficult to weld, the method of welding while assembling can also be used to complete the assembly work.
E.
In order to reduce deformation and assembly sequence, it is advisable to first assemble and weld small parts, and correct them to eliminate internal stress caused by welding as much as possible, and then assemble small parts into integral components.
F.
The steel structural components and frame steel structural components of high-rise buildings must be pre assembled in the factory.
