Novel casing pipe fixator capable of being easily assembled and disassembled and fixing method

Abstract

The invention belongs to a fixing device and a fixing method, particularly to a fixing device and a fixing method used for fixing a casing pipe in a cast-in-place floor in the engineering construction. A novel casing pipe fixator capable of being easily assembled and disassembled comprises a fixing base, wherein a screw is penetrated into the center position of the fixing base, a positioning end is formed on the end part of the screw, and the fixing base is adaptive to the internal diameter of the casing pipe and is used for fixing the casing pipe. The fixing method comprises the following steps of: determining the fixing position of an upper-layer casing pipe according to the position of a lower-layer casing pipe; penetrating the positioning end of the casing pipe fixator into the fixing position, and fastening the casing pipe fixator; sheathing the casing pipe onto the casing pipe fixator; enabling the base of the casing pipe fixator to be adaptive to the internal diameter of the casing pipe; limiting the casing pipe; and finally, covering a sealing cap, and fastening. The novel casing pipe fixator capable of being easily assembled and disassembled and the fixing method disclosed by the invention have the advantages of precise position, firmness in fixing, convenience in installation, and repeated utilization, and economic and practical effects are achieved.

Description

technical field [0001] The invention relates to a fixing device and a fixing method, in particular to a fixing device and a fixing method for fixing an inner casing of a cast-in-place floor slab during engineering construction. Background technique [0002] In engineering construction, there are usually two methods for pipelines passing through the floor: one is to reserve a square box at the place where the pipeline passes through the floor, and according to the position of the center of the square hole in the poured concrete floor, through the vertical line, the construction The center position of the square box of the layer formwork is determined, and a square box is reserved there. After the pipeline installation is completed later, the gap between the hole and the pipeline is sealed by hanging mold. This approach has the following disadvantages: (1) After the pipeline is installed, it is necessary to use concrete hanging formwork, the waterproof effect is not good, and ...
