For steel structure processing and construction, the requirements for construction quality acceptance shall not be lower than the provisions of relevant specifications.Steel structure drawing is an important document of steel structure processing construction and the basic basis of steel structure processing construction quality acceptance.So, what are the requirements of the terms in the steel structure processing construction specification?Let’s take a look at the analysis below.

The terminology requirements in steel structure processing construction specification are as follows:

 1, components

 A unit consisting of several parts, such as welded H-beam, bracket, etc.

 2, parts

 The smallest element of a component or component, such as a gusset plate, flange plate, etc.

 3,High strength bolt connection pair

 The general name of high-strength bolt and its matching nuts and washers.

  steel structure

 4, anti sliding coefficient

In high-strength bolt connection, the ratio of the external force when the friction surface of the connector is sliding to the sum of the pretensions of high-strength bolts perpendicular to the friction surface.

 5. pre-assembly

 Assembly to check whether the components meet the installation quality requirements.

6, spatial stiffness element

The basic stable space system composed of components.

 7, component

A basic unit of steel structure, such as beams, columns, supports, consisting of parts or components.

8. small assembly unit

 The minimum installation unit, except for the loose parts, is generally divided into two types: plane truss and cone.

9, middle splicing unit

The installation unit consists of the smallest installation unit other than the loose parts, which is generally divided into two types: strip type and block type.

10. ambient temperature

The temperature of the site at the time of fabrication or installation.

11. welding of studs

The method that one end of the welding pin contacts with the surface of the plate to start arc, and after the contact surface melts, the welding pin is welded with certain pressure.

Through the above analysis, there are several requirements for terms in the steel structure processing construction specification.According to the relevant requirements, the quality of steel structure processing can be guaranteed.
