What Are The Technical Requirements For Steel Structure Installation?

- Jul 25, 2018 -

The steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and the joints, bolts or rivets are usually connected between the components or components. LINGSHAN Steel Structure Company is widely used in large factories, stadiums, super high-rises and other fields because of its light weight and simple construction.


1. Before the installation of the steel structure, check the factory certificate, material test report, non-destructive inspection report of the weld, etc., and check whether the appearance of the component meets the design requirements, and the problem should be corrected immediately.

2. Drawing the steel structure installation flow chart and installing according to the flow chart. Before the installation, the accuracy of all anchor bolts should be checked, and the space position and design drawings should be corrected in time to ensure the anchor position. Accuracy.

3. The order of component installation should be carefully designed to form a rigid body as soon as possible so as to continue to maintain a stable state and to facilitate the elimination of errors in the installation of steel structures.

4. Component lifting should be carried out for necessary checking. For members with small lateral stiffness, measures should be taken to stop the distortion and damage.

5. During the installation of the column or steel structure, the beam and support should be installed in time, and if necessary, additional cable wind rope should be temporarily fixed.

6. The installation of the steel column should pay attention to the influence of the temperature difference on the verticality of the component. The adjustment side quantity is based on the verticality of the standard column determined first, and the other columns are reviewed.

7. When the column is installed, the positioning axis of each column must be directly drawn from the control axis of the ground. The top axis of the next column should not be used as the positioning axis of the upper column.


8. Steel structure installation site welding environment, welding position, high-altitude operation, air temperature and humidity are unfavorable. Therefore, it is easy to produce weld defects. Therefore, measures must be taken to overcome the influence of these unfavorable factors. Unqualified weld rework No more than two times.

9. The torque wrench used for high-strength bolts must be calibrated before use. It should be calibrated after use. Once the calibration torque error is found to exceed the allowable range, the wrenches that are applied by the wrench are unqualified.

The high-strength bolts shall be inspected after the final screwing, and the nuts may be tested one by one by a small hammer tapping method. The torque should also be tested

10. After the steel structure is installed and corrected, the gap between the column bottom plate and the top surface of the foundation should be grouted in time to make the bottom plate and the base surface tightly contact.
