Problems solved by technology

[0002] At present, the general grid structure mostly adopts the installation method of high-altitude loose assembly, or single jacking or single high-altitude sliding. The above installation methods all have the disadvantages of high installation cost and long installation period.
Especially for large-area grid installations, the above shortcomings are particularly prominent

Embodiment Construction

[0024] In order to further understand the content of the invention, features and effects of the present invention, the following embodiments are exemplified and described in detail with the accompanying drawings as follows:

[0025] see Figure 1 to Figure 3 , a construction method for the overall lifting and sliding of a grid frame, comprising the following steps: comprising the following steps:

[0026] 1) The overall lifting of the grid

[0027] After the net frame is assembled on the ground, several sets of jacking devices are evenly arranged in the net frame; each set of jacking devices includes a jacking frame and a jacking hydraulic jack 5, and the jacking frame includes One bolt ball quadrangle 10 and a plurality of bolt ball lattice column standard sections 9, the bolt ball quadrangle 10 is abutted under the steel ball of the grid;

[0028] The top of the jacking hydraulic jack 5 is provided with a jacking cap 6, and the jacking cap 6 is connected with the standard ...

Abstract

The invention discloses a construction method for integrally jacking and slipping a net frame, which comprises the following steps: firstly, net frame integral jacking: after the net frame is spliced on the ground, a plurality of jacking devices are uniformly placed in the net frame, each jacking device includes a jacking rack progressively heightened and a jacking-up hydraulic jack, and the jacking-up hydraulic jacks push the net frame to a predetermined height through the jacking racks progressively heightened; secondly, net frame integral slipping: the jacking-up hydraulic jacks are horizontally pushed by a screw jack to enable the net frame to slip to an assigned position; and thirdly, net frame mounting completion: the jacking-up hydraulic jacks fall, and the net frame falls to a structural chapiter, and then all the jacking devices and the slipping devices are dismantled. The method has the advantages that the construction speed is high, the quality control is excellent, measure investment is little, the jacking and slipping are performed continuously, the construction period is shortened, the cost is reduced, and the method is particularly suitable for large-area net frames.

Description

technical field [0001] The invention relates to a construction method for the installation of a grid frame, in particular to a construction method for the integral jacking and sliding installation of a grid frame. Background technique [0002] At present, the general grid structure mostly adopts the installation method of high-altitude splicing, or a single jacking or a single high-altitude sliding. The above installation methods all have the disadvantages of high installation cost and long installation period. Especially for large-area grid installation, the above shortcomings are particularly prominent. SUMMARY OF THE INVENTION [0003] In order to solve the technical problems existing in the known technology, the invention provides a construction method for the overall lifting and sliding of the grid frame. The grid frame is constructed by this method, which is fast and flexible in construction and requires less investment in measures. [0004] The technical scheme ado...
