Embodiment

[0047] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 5 , Figure 7 and Figure 8 Shown:

[0048] A construction method for a long-span roof steel truss structure, comprising the following steps:

[0049] 1) Installation of the jacking device: place the jacking device at the installation position, and fix the base 1 on the ground; install the steel truss 29 in the installation groove 24 of the support base 7, and fix the steel truss 29 on the support base 7 superior;

[0050] 2), jacking operation: energize the second electromagnet 12 on the lower support frame 3, utilize the second electromagnet 12 on the lower support frame 3 to fix the lower support frame 3 and the support column 2; start the hydraulic cylinder 5 to The support base 7 and the steel truss 29 are lifted together, and the hydraulic cylinder 5 also pushes the upper support frame 4 to move upward; when the stroke distance of the hydraulic cylinder 5 reaches the maximum, the se...

Abstract

The invention relates to the field of building construction, and specifically discloses a construction method for a steel truss structure on a large-span roof, comprising the following steps: 1), installation of a jacking device; 2), jacking operation; 3), adjustment of the jacking process; 4) , the range of jacking height is adjusted; 5), the anti-falling measures are carried out; 6), the anti-overturning measures are carried out; 7), the jacking device is reset; Insufficient in efficiency and stability, etc., it is impossible to efficiently and safely complete the lifting of super-high roof steel trusses.

Description

technical field [0001] The invention relates to the technical field of building construction, and specifically discloses a construction method for a large-span roof steel truss structure. Background technique [0002] The steel truss itself can adapt to the distribution of bending moment and shear force inside the structure. Since the internal force of tension and compression in the horizontal direction achieves its own balance, the entire structure does not generate horizontal thrust on the support, so it is widely used in the construction field. Steel trusses are mostly installed by hoisting. When installing steel trusses by hoisting, a large and unobstructed space is required. At the same time, traction control of steel trusses is required to ensure the lifting accuracy of steel trusses, and it can also prevent steel trusses from colliding with walls, causing The steel truss and the wall are damaged; and the steel truss is installed by jacking, which does not require a la...
