Fixing device for pre-embedded casing pipe and reserved hole and using method

Abstract

The invention provides a fixing device for a pre-embedded casing pipe and a reserved hole. The fixing device is used for steel bar binding of reinforced concrete and comprises a bottom plate and a screw. The fixing device is characterized in that the bottom plate (4) is a rectangular or square steel plate, and at least two screw holes (6) are formed in the edge of the bottom plate; the screw (1) is a full-wire screw with the diameter greater than or equal to 12 mm, and the screw is provided with a nut (2) in a matched mode; and one end of the screw (1) is welded and fixed to the center of thebottom plate, and the screw is perpendicular to the bottom plate. The fixing device for the pre-embedded casing pipe and the reserved hole and a using method have the advantages that the fixing deviceis simple in structure, manufacturing is quick and convenient, the quality of the pre-embedded casing pipe and the reserved hole are safe and reliable so as to achieve the effect of non-deviation andnon-moving of the pre-embedded casing pipe, fixing operation of the casing pipe is easy, the installation efficiency is greatly improved, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a fixing device for pre-embedded sleeves and reserved holes, in particular to a fixing device for pre-embedded sleeves and reserved holes used in the binding of reinforced concrete steel bars and a method of use. Background technique [0002] The Hanjiashu resettlement housing project in Beichen District, Tianjin has a total of 10 buildings, with about 1,200 floor casings, which is an extremely large number. During the pouring of concrete in the construction stage, the position of the casing is easily shifted due to the pouring of concrete, which causes more difficulties in the later pipeline installation. If the traditional way of fixing steel wires to the steel bars is used, the position is prone to shift when the concrete is poured, and the embedded casing is deflected due to the deformation of the steel bars during pouring. After the steel bars are poured, the casing needs to be inspected. , finding skew requires manual pr...

AI Technical Summary

Problems solved by technology

During the pouring of concrete during the construction stage, the position of the casing is easily shifted due to the pouring of the concrete, which causes more difficulties in the later installation of the pipeline

If the traditional way of fixing steel wires to the steel bars is used, the position is prone to shift when the concrete is poured, and the embedded casing is deflected due to the deformation of the steel bars during pouring. After the steel bars are poured, the casing needs to be inspected. , finding skew takes manual processing

When the position of the casing deviates greatly, it may cause the casing and the reserved holes to be invalidated, and the hole needs to be re-drilled

[0003] Therefore, there are above-mentioned inconveniences and problems in the known steel wire binding and fixing method of embedded casing.
