Embodiment Construction

[0028] like figure 1 , figure 2 As shown, the jacking device 1 of the present invention includes two jacks 1-2 arranged side by side, a base 1-1 is arranged at the bottom of each jack 1-2, and a base 1-1 is arranged at the top of the cylinder shafts of the two jacks 1-2. There are horizontal beams 1-3, and the two ends of the beams 1-3 are respectively provided with limiting blocks 1-4. The two ends of the bottom surface of the beam 1-3 are fixed with a fixed sleeve 1-5, and the top of the cylinder shaft of the jack 1-2 is inserted into the fixed sleeve 1-5. The distance between the two jacks 1-2 is about 1 meter, and the maximum distance is no more than 1.2 meters. When in use, the two jacks 1-2 of the jacking device 1 are lifted and lowered at the same time, so that the beam 1-3 is always kept in a horizontal state.

[0029] The jacking device 1 is supported by two jacks 1-2 to support a horizontal beam 1-3, the beam 1-3 is used to support the grid ball node 1-6, and the...

Abstract

The invention relates to a unilateral jacking and external expansion method of a network frame. The jacking device includes two jacks arranged side by side, a base is arranged at the bottom of each jack, and a horizontal beam is arranged at the top of the cylinder shafts of the two jacks. , There are limit blocks at both ends of the beam. Fixed sleeves are fixed at both ends of the bottom surface of the beam, and the top of the cylinder shaft of the jack is plugged into the fixed sleeves. The unilateral jacking and external expansion method of the grid frame uses the above-mentioned jacking device. One end of the grid frame is hinged on the hinged support, and the free end of the grid frame is lifted to a certain height using the jacking device, and then along the original The grid continues to be spliced, and the jacking device is installed at the new free end, and the grid is spliced ​​through multiple jacking and splicing until the grid is completely spliced. The invention solves the problem that the jacking device needs to move frequently during construction, shortens the construction period, and the jacking device has a simple structure, can be recycled repeatedly, and saves construction costs.

Description

technical field [0001] The invention relates to an auxiliary equipment for network frame construction, in particular to a single-side jacking and external expansion method for a network frame. Background technique [0002] With the rapid development and increasing popularity of steel structure grids, there are new requirements for the construction methods and construction efficiency of grid structures. In many cases, the construction site is very limited, and construction and production need to be carried out simultaneously, and construction must be carried out without affecting production. The construction period of the network frame is tight and the time is short. It is necessary to quickly complete the construction of the network frame with a large span and a large weight, and it is necessary to ensure the construction quality and safety. Nowadays, most of them use the unilateral jacking and external expansion method for the construction of large-span and heavy-weight gr...
