Embodiment Construction
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] like figure 1 and figure 2 As shown, the installation method of the rear supplementary rod and the lifting rod for the overall lifting of the grid frame of the present invention includes the following steps:
[0018] Before lifting the grid 1, a rear supplementary rod 8 for fixing the grid 1 to the existing structure is provided, the rear supplementary rod 8 is divided into a first section 3 and a second section 4, and the One end of a section 3 is fixed to the position to be lifted on the grid 1;
[0019] Provide a lifting device, fix the lifting rod 2 in the lifting device at the position to be lifted, make the lifting rod 2 intersect with the first section 3, and fix the intersection with the first section 3 ;
[0020] The net frame 1 is lifted by the lifting device until it reaches the specified height;
[0021] Fixing the second section ...

The invention relates to a rear supplementary rod for integral lifting of a grid frame and a method for installing a lifting rod, comprising the following steps: before the grid frame is lifted, a rear supplementary rod for fixing the grid frame to an existing structure is provided; The rear supplementary rod is divided into a first section and a second section, and one end of the first section is fixed to the position to be lifted on the grid; a lifting device is provided, and the lifting rod in the lifting device is fixed to the At the position to be lifted, make the lifting rod intersect with the first section, and fix the intersecting position with the first section; lift the grid through the lifting device until it reaches a specified height; The second section is fixed to the first section to form the rear supplementary rod, the rear supplementary rod is fixed to the existing structure; the lifting rod is removed. The present invention solves the problem of conflict between the rear supplementary rod and the lifting rod in the prior art after the large-scale grid frame is lifted by breaking the rear supplementary rod into two sections for fixing respectively.
Description
technical field [0001] The invention relates to the field of building construction, in particular to an installation method for a rear supplementary rod and a lifting rod for the integral lifting of a grid frame. Background technique [0002] In the prior art, the overall lifting of the large-scale grid is usually carried out by using lifting rods as the connecting lifting frame. After the grid is lifted in place as a whole, the post-replenishing rods are installed on the support of the grid, so as to make the grid. Fix, then cut off the lifting rod to unload. In order to ensure that the welding seam of the lifting rod and the back-up rod after being lifted in place is complete and the strength meets the requirements, usually the lifting rod and the back-up rod are avoided and intersected. However, some large-scale grids have high load-bearing requirements. , so that the diameter of the rear supplementary rod is larger, so that it is difficult for the lifting rod to avoid c...
