Abstract
The invention relates to a fixing method of a through floor slab reserved sleeve, which comprises the following steps: firstly, the method comprises the following steps: the civil engineering specialty completes formwork support and bottom bar binding; II, secondly: the method comprises the following steps that a reserved hole is located for water supply and drainage professionally, a steel sleeve is placed at the located position, a wood cover plate is placed at the upper end of the sleeve, and a 250mm drill tail hexagon head screw is used for penetrating and fixing the sleeve to a template; thirdly, the method comprises the following steps: the drill tail hexagon head screw can be selected according to the height of the sleeve; fourthly, the method comprises the following steps: after concrete is poured in the civil engineering major, dismantling the fixing screw of the steel sleeve after the concrete is initially set, and taking out the sleeve; fifthly: after the sleeve is removed, the reserved hole is neat and attractive, and no steel wire is left in the concrete. The invention improves the existing sleeve fixing mode, can avoid steel wires remained in concrete and reduce leakage risk.
Description
Technical Field
The invention relates to a sleeve fixing mode, in particular to a method for fixing a reserved sleeve penetrating through a floor slab.
Background
According to the traditional reserved sleeve fixing mode, after concrete is poured and the sleeve is taken out, the thin steel wires are still in the concrete, and through seams or holes can be formed along with corrosion of the steel wires in the concrete, so that leakage hidden danger is caused; when a hole is reserved, only an iron wire at the fixed handle is generally cut off, namely the sleeve is pulled out, after the sleeve is removed, a steel wire and an iron nail are reserved at the edge of the reserved hole and attached to a floor slab, and the reserved hole is not attractive; if the fixed sleeve is fixed by iron wires, the fixed sleeve cannot be completely removed, and a through hole or a seam is formed due to corrosion of the residual iron wires, so that the concrete structure leaks;
the reserved sleeve is poor in pore-forming quality after being taken out, a concrete structure gap can be formed by the fixing iron nails, and the subsequent mould hanging quality risk is increased.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a fixing method of a through floor slab reserved sleeve, and solves the problem of residual steel wires in concrete.
In order to solve the technical problem, the invention is realized as follows:
a method for fixing a reserved sleeve penetrating a floor slab is characterized by comprising the following steps:
the method comprises the following steps: the civil engineering specialty completes formwork support and bottom bar binding;
step two: the method comprises the following steps that a reserved hole is located for water supply and drainage professionally, a steel sleeve is placed at the located position, a wood cover plate is placed at the upper end of the sleeve, and a 250mm drill tail hexagon head screw is used for penetrating and fixing the sleeve to a template;
step three: the drill tail hexagon head screw can be selected according to the height of the sleeve;
step four: after concrete is poured in the civil engineering major, dismantling the fixing screw of the steel sleeve after the concrete is initially set, and taking out the sleeve;
step five: after the sleeve is removed, the reserved hole is neat and attractive, and no steel wire is left in the concrete.
The invention has the beneficial effects that: after the sleeve is removed, no iron nail is attached to the concrete, no steel wire is left, and the appearance is neat; when the sleeve is reserved, after concrete is poured, no binding wire, iron nail and other residues exist on the contact surface of the sleeve and the floor slab; when a hole is reserved for hanging the mould, the mould can be hung only by chiseling the reserved hole opening; the drill tail hexagon head screw and the hole casing pipe can be recycled, and certain economical efficiency is achieved.
Drawings
The invention is described in further detail below with reference to the following figures and embodiments:
fig. 1 is a schematic structural diagram of the present application.
Detailed Description
As shown in fig. 1: a fixing method of a pre-arranged sleeve penetrating a floor slab,
1. preparing materials:
1) selecting screws with proper sizes according to requirements;
2) various materials such as water supply and drainage, electric, heating and ventilation, fire fighting and the like required by the installation of the sleeve;
2. the application range is as follows: fixing a sleeve penetrating through a reserved hole of a floor slab;
3. the method comprises the following steps:
the method comprises the following steps: the civil engineering specialty completes formwork support and bottom bar binding;
step two: the method comprises the following steps that a reserved hole is located for water supply and drainage professionally, a steel sleeve 2 is placed at the located position, a wood cover plate 4 is placed at the upper end of the steel sleeve, a 250mm tail-drilling hexagon head screw 3 is used for penetrating and fixing the steel sleeve to a template 1, and a handle 5 is installed on the cover plate;
step three: the drill tail hexagon head screw can be selected according to the height of the sleeve;
step four: after concrete is poured in the civil engineering major, dismantling the fixing screw of the steel sleeve after the concrete is initially set, and taking out the sleeve;
step five: after the sleeve is removed, the reserved hole is neat and attractive, and no steel wire is left in the concrete.
