What problems should be paid attention to in the installation of construction engineering steel structure?

What are some precautions for the installation of building steel structures? Steel structures are widely used in large workshops, stadiums, super high-rises and other fields because of their light weight and easy construction. However, many people still don't know how to install the steel structure. Below, the steel structure fabricators will introduce the problems to be paid attention to in the installation of the steel structure in detail.

Steel structure installation must strictly control materials

For the installation of steel structure workshop, the material is very important. The variety, model, specification and quality of the steel should meet the design requirements and the relevant product standards implemented by the country, and can be used only after passing the random sampling re-examination. In addition, electrodes, welders and fluxes with matching factory certificates should be selected according to the steel grade.

Steel structure installation requires strict screening of personnel

The installation of the building steel structure mainly uses welded rivet bolts. Therefore, it is necessary to focus on checking the technical qualification certificates of special types of work such as welders and crane workers, operating safety certificates, and checking the qualifications and validity periods of the certificate issuing units. At the same time, the project department established a quality assurance system, implemented three inspection systems, and required technicians to obtain certification.

Steel structure engineering installation should pay attention to steel structure connection

Steel structure refers to a structure in which parts or parts are made of steel (steel, plate), and then connected together by a certain connection method. The quality of the connection directly affects the safety of the entire structure. Correct selection of connection methods and reasonable design of connection forms are an important part of steel structure engineering installation. Reasonable connection design should comply with the principles of safety, simple structure, clear electrical conductivity, convenient construction, and steel saving.

The installation of building steel structure should be offset by buried anchor bolts

Embedded anchor bolts are a key work item on the installation and construction site of the steel structure workshop, and the construction unit must be required to prepare and construct a special construction plan.

Steel structure installation should pay attention to the deviation of parts assembly

Because components deform during transportation and stacking, flexural deformation may occur after lifting, and accumulated errors during installation may lead to deviations in component assembly. Therefore, effective protection measures should be taken during the loading and transportation process of parts, and the loading and unloading stack must be level. The lifting position of large parts should be confirmed by calculation. When deviations are found, the reasons should be found in time and adjustments should be made.

If the deviation is found to be too large during the installation of the steel structure of the construction project, it must not be forcibly corrected or expanded at will. The design should be submitted and technical corrective measures should be taken to solve it.

Canglong steel structure fabricators remind that safety must be paid attention to when installing steel structures, and relevant preventive measures must be taken before construction.
