   In the steel structure has the greatest advantage in different forms of structure using a different installation process, the steel structure through the bottom to the top, single to multi-storey development model, in the continuous exploration of progress, the industry structure to promote the industry Of the role, then the spatial structure refers to those aspects?
   First, the overall lifting mode, grid or truss as a whole to enhance the method, refers to the ground after the grid or truss after the total battle, the use of single or multi-pole, one or more cranes to lift the construction method in place. In the overall plan of the field and the misplaced plan, the frame or trusses in the air after the other side (moment) shape needs to be translated after the circular structure in the air needs to be rotated by an angle and then down the procedure applies to the lifting rod The OTC program for crawler cranes. This kind of construction method is typical of the construction of the Olympic project in the construction of the old mountain bike museum
   Second, the segment or block installation method, respectively, refers to the segment or block unit, respectively, by the crane to the high-altitude design position in place, and then assembled into the overall installation. Beijing Olympic basketball hall steel structure project, the National Stadium steel structure project in this way to install.
The overall lifting method, grid or truss as a whole means of lifting, refers to the grid or truss in the ground after the overall battle, the use of single or multi-pole, one or more cranes to lift the construction method in place. In the overall plan of the field and the misplaced plan, the frame or trusses in the air after the other side (moment) shape needs to be translated after the circular structure in the air needs to be rotated by an angle and then down the procedure applies to the lifting rod The OTC program for crawler cranes. This construction method is typical of the construction of the Olympic project in the construction of the old mountain bike museum.
   Third, the overall upgrade mode, refers to the grid together on the ground, with lifting equipment (usually hydraulic jack) will be raised to the overall design of the vertical grid elevation and fixed mode. Use this method to install the National Convention Center project. High-altitude bulk means that small combat units or components directly in the design site to conduct a comprehensive blow to the way. The high-altitude bulk method has a complete stent (ie full of scaffolding) method and cantilever method two. A full-frame method for spare parts assembly, and a cantilever method for small combat units in high-altitude total or spherical grid triangular grids. National stadium steel structure project is the use of high-altitude bulk method for installation.
   In addition to the construction of the system of theoretical construction, the domestic steel structure construction enterprises in the steel structure construction has also experienced a large number of large steel structure construction reference materials and experience. For the future development of steel enterprises, China's overall level of steel construction will have a profound impact.http://www.dreamhouseowner.com/
