工业厂房钢结构安装施工(国外英文资料)Simultaneous correction and finally fixed vertical degree, the perpendicularity of the roof truss with hammer hanging line inspection, roof truss after correction, can install support and sommer, etc., and finally fixed end screw bolt. ?3, the component installation?It is especially important to ensure that the vertical, axis and elevation parameters are guaranteed. Before installation, start the line and make the point of the steel column to be positive, so as to ensure the direction of the column is accurate. The bottom of the column should be made up of inclined iron to adjust. After the column is installed, make coarse adjustment, roughly adjust its vertical degree to make it easy to install the steel girder. The steel girder should be made clear before the steel girder, so as to ensure the surface area. After all the main beam is installed, the vertical steel column will be fine. Use the level of the water level and the transit instrument to be used within the distance to prevent the data from being invalid. For the lighter stair column and stair beam and so on the component can complete the assembling on the ground and then the disposable suspension. After the vertical bar is inspected, the bolt will be welded. In a high-strength bolt installation, the bolts should be in the same direction and the bolts should be in the top of the steel beams to ensure the appearance. Each set of bolts should be consistent, and the aperture should not be more than 1.2 times the diameter of the design aperture. To ensure the surface area of the friction surface before piercing. If the clearance is less than 1.0 mm, it will not be processed; In the range of 1.0 ~ 3.0mm, the side of the connection plate can be ground to 1:10, and the direction of grinding is perpendicular to the force. When fastening should be early twist, twist, twist, twist is early to narrow because of the influence of the steel plate deformation in the process of fastening bolts, take measu
