Description

A penetration sleeve (Penetration sleeve), which is installed by varying the length in accordance with the width of the mold,

The present invention relates to a through sleeve for constructing a through hole for installing a pipe or an electric wire on a wall, and more particularly, to a method of manufacturing a through sleeve using a steel pipe to prevent the occurrence of a fire or poisonous gas when a fire occurs, The length of the penetrating sleeve is adjusted instantaneously at the construction site according to the thickness of the wall which varies at the time of installation.

Generally, a wall of a building is formed with a through hole through which pipes are inserted for installing pipes for ventilation, cooling, heating, sprinkler, electric wiring, sewage, and the like.

Therefore, in order to form the through holes in the wall, the foundation reinforcement bars are installed at regular intervals, the wood or aluminum formwork is installed outside the reinforcing bars, and the inside of the through holes of the formwork is provided with an arm, Which is adjustable in length or automatically controlled in length by an elastic body, is fixed by a nail or the like, thereby providing ease of installation.

However, such a through sleeve has a length of a predetermined length, and the through-hole sleeve having such a predetermined length may vary in thickness of the wall to be installed in the field. Therefore, when the through sleeve is installed, And there were many difficulties in construction such as failure to fit.

In recent years, the Fire Service Act has taken countermeasures to prevent the generation of toxic gas as well as preventing the spread of fire in the event of a building fire. Most of the through sleeves are made of PVC material. Such PVC material is very vulnerable to heat Which is a cause of generation of toxic gas, has a problem of being extremely vulnerable to fire.

Therefore, although it has been proposed to use a steel pipe having a strong heat resistance, there is a problem that such a steel pipe can not be fixed properly to the formwork and thus it is not used properly.

Patent No. 10-1243498 (Mar. 03, 2013)

Accordingly, it is an object of the present invention to provide a pipe structure which can prevent the generation of toxic gas due to fire while permitting use of both PVC pipes and metal pipes, The length of the through-pipe is immediately cut in the field according to the interval width of the through-hole, and the cut-through pipe is contracted by the elastic action and is connected to the through sleeve which is automatically restored to adjust the length thereof so that the through- .

To this end, in the present invention, a body is formed as a tubular body and has a cover plate for fixing to a workpiece separated by a perforated line on one side thereof, and a guide hole having an elastic body mounted inside the body, And a length adjuster made of a tube having a guide bar formed on its side is coupled to the length adjuster so that the length adjuster is fixed to the other die, And the through-pipe that is directly cut in the field is installed between the pipe and the pipe.

Therefore, in the present invention, when the formwork installed to construct the wall is varied according to the thickness of the wall in the construction site, the through-pipe can be directly cut in the product or the field already prepared to fit the formwork to adjust the length of the through- Thereby providing ease of use.

In addition, by using a strong steel pipe to heat the penetrating sleeve, it is possible to prevent a safety accident caused by a fire.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1, the present invention is characterized in that the present invention comprises a body 10 having a body and a guide hole 13 formed on a side thereof, a projection 10 formed at one side of the body 10 through the perforated line 11, And a length adjuster 20 having a tubular body formed with a guide protrusion 21 on a side thereof so as to fit into the guide hole 13 on the other side surface of the main body 10, And the elastic body 30 is mounted on the inside of the guide hole 13 so that the length adjusting body 20 is contracted and restored by the elasticity of the elastic body 30 when the length adjusting body 20 is pressed inside the body 10. [ .

At this time, the guide hole 13 is formed on only one side of the side surface of the main body 10 or is symmetrically formed on both sides, and the guide protrusion 21 formed on the length adjuster 20 is also formed on only one side Formed or symmetrically biased.

At this time, a through pipe 40 having an interval equal to the interval width of the form 100 already installed at the construction site is used or cut in the length adjuster 20 to adjust the cut through pipe 40 to the length adjuster 20, The length adjusting body 20 is contracted to the inside of the main body 10 by the elastic body 30 and then placed in the installation space of the mold 100 and then the pressure is released The length adjuster 20 is automatically restored and installed in accordance with the gap width of the formwork 100. [

At this time, it is possible to use a pipe made of PVC which is integrally formed with the cover plate 41 formed with a projection on one side and separated by the perforated line 42, and a steel pipe of a metal material is also used Such a steel pipe prevents fire from spreading or prevents the generation of toxic gas when a fire occurs.

However, the material of the through-pipe 40 does not limit the object of the present invention.

In the case where the through-pipe 40 having a predetermined length is not fitted to the width of the mold 100, the length of the through-pipe 40a can be adjusted by using the extension pipe 40a. And the cover plate 41 having the projections for fixing to the formwork 100 formed on one side thereof is separated from the perforated line 42 by the step formed on the intermediate portion of the body for the connection to the through pipe 40. [ .

Therefore, when the penetrating sleeve is installed in the formwork 100 already installed, a through-pipe 40 of a regular length made of a PVC material is used in accordance with the interval width of the form 100, or the cut- The length of the through sleeve can be adjusted by the elasticity of the length adjuster 20 when it is coupled to the through sleeve.
