Problems solved by technology

[0005] However, during the jacking process of the grid structure, the jacking support system generates horizontal load due to uneven force, and then the grid center shifts, causing the grid frame to overturn, the construction safety and reliability are low, and it is difficult to guarantee the construction quality

Embodiment Construction

[0054] The present invention will be further described below in conjunction with accompanying drawing:

[0055] 【Example】

[0056] Such as Figure 1-6 As shown, an overall jacking device for a large-span network frame includes a measure bracket 1, a jacking bracket 2, a guide rail 3, a hydraulic jack 4, a limiting anti-overturning bracket 5 and a stirrup 6.

[0057] The measure support 1 is an umbrella-shaped support, the measure support 1 top is connected with the grid frame 7, and the measure support 1 bottom is fixed on the jacking support 2 top. Measures There are one set of jacking brackets 2 on the left and right sides of the bottom of the bracket 1, flanges are provided on the top and bottom of the jacking brackets 2, and multiple jacking brackets are connected by flanges. Each group of jacking brackets 2 consists of multiple A jacking bracket 2 is formed by connecting end to end successively from top to bottom. The present invention also includes a middle bearing pl...

Abstract

The invention relates to the technical field of large-span grid construction, in particular to an overall jacking method for a large-span grid and a position limiting and anti-tipping device. Including measure bracket, jacking bracket, guide rail, hydraulic jack, limit anti-overturn bracket and stirrup. It includes the following steps: step 1, preparation for jacking, step 2, installation of jacking device, step 3, pre-jacking, step 4, jacking, step 5, structural edge sealing in place, step 6: support removal; The displacement generated during the overall lifting process of the frame can share the horizontal load caused by the uneven force of the jacking support system, greatly improve the construction safety and reliability of the original process, better control the center displacement of the grid frame, and improve the construction quality.

Description

technical field [0001] The invention relates to the technical field of large-span grid construction, in particular to an overall jacking method for a large-span grid and a position limiting and anti-tipping device. Background technique [0002] The rapid development and wide application of the grid structure in the past 30 to 40 years is mainly due to its own characteristics such as high rigidity, good integrity, and strong earthquake resistance; light weight, saving steel, and convenient construction. It can be applied to buildings with various spans and plane shapes. Especially large-scale shopping malls, aircraft hangars, stadiums and other long-span structures. [0003] There are six commonly used methods for field installation of grids: high-altitude bulk method, strip and block installation method, high-altitude sliding method, overall hoisting method, overall lifting method and overall jacking method. [0004] The large-span network frame jacking technology, because...
