Steel grid rod assembling type replacing device

Abstract

The invention discloses a steel grid rod assembling type replacement device which comprises a central plate, side supporting blocks and a replacement supporting piece, wherein the side supporting blocks are provided with two groups and are respectively welded with two sides of the central plate. A first telescopic rod is welded on one side of the two groups of side supporting blocks which are faraway from each other; one end of the two groups of first telescopic rods far away from the side supporting blocks is respectively welded with the bottoms of the side walls of the two groups of outer supporting plates. Two groups of second telescopic rods are also arranged on the two sides of the central plate; the two groups of second telescopic rods are respectively arranged on the two sides of the side supporting blocks, one end of which is respectively welded with the side walls on the two opposite sides of the central plate. According to the steel grid rod assembling type replacement device, the first telescopic rods, the outer supporting plates and the replacement supporting pieces are arranged, so that the two groups of the first telescopic rods are driven to extend, and the two groups of the replacement supporting pieces are respectively inserted into notches at two ends of the steel grid, so that the steel grid can be supported and stable.

Description

technical field [0001] The invention belongs to the technical field of steel grid construction, and in particular relates to an assembled replacement device for steel grid rods. Background technique [0002] The steel grid structure can be divided into flat steel grid and curved steel grid according to the shape. Usually, the flat steel grid is called steel grid; the curved steel grid is called steel grid shell. The steel frame rod is a curved grid structure, which has the characteristics of both the rod system structure and the thin shell structure. The force is reasonable and the covering span is large. A spatial structure with broad prospects for development. [0003] Steel grid rods often need to be replaced after long-term use, but the existing steel grid rod replacement device has the following problems to be solved: 1. It cannot effectively support the steel grid to be replaced, and it is not stable enough during replacement ; 2. The outer wall of the steel grid ro...
