Problems solved by technology

However, the conventional scheme has the following problems: the material used for supporting and splicing tire frames is large, and the reuse rate of tire frame materials is very low; a large crane with a large tonnage is required and the cost is high; high-altitude operations have low construction efficiency and poor safety; high-altitude tailor welding construction Difficulty, quality is not easy to control; the construction time is long and affected by environmental factors (such as strong wind, precipitation, etc.) special measures must be taken to prevent components from overturning when splicing components at high altitude; the construction of the assembly operation platform is heavy and labor-intensive

Embodiment Construction

[0036] figure 1 A plan view of a steel roof system is shown in . The entire steel roof system has a total of 26 secondary trusses 2 placed in parallel, and circumferential ring trusses 3 are arranged around the secondary trusses 2, and there are longitudinally arranged main trusses 1 and 1 in the middle of all the arranged secondary trusses 2 , the secondary truss 2 and the hoop truss 3 are fixed to each other and supported by the supporting steel column 4 . The main steel structure of the roof covering the entire venue space is formed by the rigid connection of two long-span space main trusses with a span of 320 meters in the longitudinal direction, 26 latitudinal secondary trusses with a maximum span of 224 meters (average span 190 meters), and ring trusses. The cross section of the main truss is usually divided into upper and lower parts, the upper section width is 4m, the height is about 4~4.5m (intersecting with the ellipsoid), the lower part is approximately trapezoidal...

Abstract

The integral building truss lifting method features that the lifting process includes assembling the main truss on ground in two units; manufacturing and installing corresponding lifting frame; setting cable system on the elevating frame and installing hydraulic elevator in corresponding position; installing the truss ground end shifting units; lifting the two elevated ends of the truss units with the hydraulic elevator synchronously while ensuring the horizontal shift of the ground ends of the truss units under the control of main computer; dismantling the ground end shifting units after the overhead butt joints are in place; elevating and fixing the ground ends; and assembling the overhead butt joints.

Description

technical field [0001] The invention relates to a construction method for installing building trusses, in particular, the invention relates to a construction method for overall lifting of building trusses and equipment used in the construction method. Background technique [0002] Since the strength of steel is higher than that of reinforced concrete, and its weight is lighter than that of reinforced concrete, it is widely used in high-rise buildings, especially in some large stadium buildings. Steel structures are mostly used in some large venues with a construction area of ​​over 10,000 square meters. However, the steel structure technology is complicated, the construction is difficult, and the construction cost is high. Moreover, the construction quality, construction speed, and construction cost cannot meet the requirements. [0003] For example, a gymnasium covering an area of ​​more than 120,000 square meters has a construction area of ​​more than 40,000 square meters,...
