Steel structure plant should be carefully inspected before construction

Before the construction of the steel structure plant, it should be carefully and comprehensively inspected, and the inspection content should include the flatness, total number, length, bolt holes at the joints, etc. Quality defects and structural deformation seen throughout the transportation process should be completed as planned and the corresponding records should be strengthened. The steel column of the steel structure plant is basically connected with the chemical bolt of the concrete column. Before installing the steel column, check the consistency of the external threads of the chemical bolts of the concrete column, the relative height of the bolts of the front concrete column, and the basic design elevation. If product quality problems are found, they should be repaired immediately and the corresponding records should be strengthened.

The connection between the steel column and the steel structure workshop frame is generally fixed and welded by bolts. Before installation, check the quality of the steel column and frame bolt holes, check the scraping of the bearing plate, and strengthen the corresponding records. The connection thickness of the crane beam and the steel column is 10mm filler plate. When installing the crane beam, if the shortcomings and deviations of the crane beam are found during the production and installation process, the thickness of the filling plate between the column and the crane beam should be adjusted immediately. There is no need to continue to accumulate this deviation on the stigma.

When hoisting parts, the appropriate way should be selected according to the details of the production site and construction site, and the appropriate safe construction plan should be formulated. After the parts are hoisted in time, the support points of the prefabricated components and the combined prefabricated components should be tied immediately to ensure the reliability of the engineering structural parts. After the lower prefabricated components are in place, all upper prefabricated components shall be hoisted, while ensuring that the calibration is up to standard and the support point prefabricated components are fastened. In the process of installation and use, according to the working capacity of the crane, the assembly of components and installation modules on the floor to minimize the working time and labor of high-altitude work. When carrying out civilized construction care at the assembly construction site, it should be ensured that large and medium-sized prefabricated components are not floor-mounted, and that they are spliced at any time and installed immediately. Minimize the construction period and prevent secondary pollution of prefabricated components. Small components entering the construction site should be uniformly stacked in a specific area, all components should not be in contact with the road surface, and the wooden square pad should be selected in a full range, and the pad point should not be less than 2. At the same time, in order to further increase the capital investment in safety production, steel wire ropes, support beams, truss beams, crane beams are set within the roof frame, to improve the level of publicity and education of construction personnel in safe production and civilized construction, to check the site civilized construction and safe production at any time, and to deal with actual operation and safety risks at any time.
