What are the installation steps of the steel structure fabricated warehouse?

Preparatory work for the installation of steel structure fabricated warehouse

1. Construction organization design

The construction organization design of the steel structure installation of the fabricated warehouse should briefly describe the project overview, comprehensively count the engineering quantity, accurately select construction tools and construction methods, reasonably arrange the installation sequence, specifically formulate the main installation technical measures, strictly formulate the installation quality standards and safety standards, Carefully prepare project schedules, labor plans, and material supply plans.

2. Inspection before construction

The pre-construction inspection of the steel structure fabricated warehouse includes the acceptance of steel components, the maintenance of construction tools and measuring tools, and the retest of the foundation.

The steel structure of the fabricated warehouse shall be checked and accepted according to the construction drawings and specification requirements. When the steel components are transported to the site, the manufacturer shall provide the product delivery certificate and the following technical documents:

a. Design drawings and design modification documents.

b. Quality assurance sheet or test report for steel and auxiliary materials.

c. Test data of friction coefficient of high-strength bolts.

d. Lectures on maintenance of class 1 and 2 welds in factories.

e. Lecture on maintenance of geometric dimensions of steel components.

f. Component list.

The installation unit should check and accept this, and retest the actual condition of the components. If the component is damaged during transportation, the manufacturer must be required to repair it.

Maintenance of construction tools and measuring tools Before installation, the important hoisting machinery, tools, wire ropes and other accessories must be overhauled to ensure reliable functions and smooth and safe installation. During the installation of the steel structure of the fabricated warehouse, the measuring instruments and tools should be inspected and calibrated by the inspection unit designated by the Bureau of Standards on a regular basis to ensure the accuracy of the measurement scale.

3. Basic retest

The steel structure is fixed on the steel concrete base (foundation, column top, corbel, etc.). Therefore, the correctness and strength of the base and its tracing bolts should be retested. The retest of the foundation should measure the horizontal elevation and flatness of the foundation surface, the deviation of the horizontal position of the anchor bolt, and the correctness of the anchor bolt embedding. And deliver the retest results and rectification requirements to the base construction unit.

4. Prepare construction plan

Prepare the installation plan and component supply plan, and organize the construction.

5. Check the steel structure

The steel structure of the fabricated warehouse should have a factory certificate when it leaves the factory, and check and check the components according to the drawings before installation. Transport the components to the installation range in accordance with the installation sequence, and try to place the components below the installation location without affecting the installation to ensure the convenience of installation.
