The installation quality of the steel structure prefab warehouse is the key issue of the entire structure. The completion of the installation quality means that the safety and stability of the entire structure are effectively improved. The selection of suitable steel is also a key issue for the installation quality of the XGZ steel structure prefab warehouse. So what are the requirements for the installation, measurement and control of steel structure prefab warehouses?
Before installing the steel structure prefab warehouse building, all steel components must be prepared, the quality of the steel components should be checked, the design drawings, construction requirements and other preparations can be reviewed before the installation of the steel structure factory building can be carried out. After determining the measurement reference point provided by the steel structure factory building, the measurement accuracy of the reference point (line) should be calibrated, and the accuracy of the reference point data and data should be reviewed.
Based on the measurement reference points (lines) provided by the design drawings, according to the national surveying and mapping standards and the construction accuracy requirements of the project, set the control network for the project, the construction baseline, positioning points, control points and construction reference points of the steel structure factory building After the measurement, the standard piles must be inspected, and the accuracy of the measurement and positioning points must comply with the relevant regulations. The management personnel at the construction site shall be responsible for protecting the measurement reference points, reference lines and leveling points, as well as the control network points added by themselves, and provide roads and protective railings leading to the network points. The missing and damaged measuring points shall be repaired.
After the steel structure of the steel structure prefab warehouse is installed, when the joint deformation data of the steel structure is measured at the same time every day as the basis of the control data, appropriate corrections should be made if necessary. All test data are retained as a basis, and the deviation of some steel components should be corrected in time before installation.
