KR200412683Y1 - Wall through sleeve - Google Patents

Abstract

Of the walls to smooth the pipes through the walls of the concrete building.

When embedding the sleeve in the formwork, the width of the wall is narrow and obstacles such as the back muscles

Regardless of whether you want to install quickly and accurately

It is a wall through sleeve developed by applying the principle of bolt and nut.

 sleeve. Back muscles. live. Thread. Internal thread, washer bolt. flange.

4; State of Use Section of the Invention

Concrete such as landfill and high-rise apartment or building with drain pipe of retaining wall embankment of civil engineering work
When constructing a new building, smooth piping work through the wall later
To pierce the sleeve at a certain position within the wall formwork before
Buried in the past, conventionally cut PVC pipe and each of the three to four nails on each end
The construction was done by drilling the hole at an angle and fixing it to the formwork.
And combine the large tube with female thread and the small tube with male thread
An adjustable piping sleeve has been devised, but this design is
Problem that is hard to cope actively with kind of wall or retaining wall that varies widely
It has not been put to practical use.

The problem with the construction in the above way is due to the characteristics of the wall

It's a narrow, linear work, so the length of the sleeve

If it is made consistent, it will be difficult to construct, so the sleeve tube should be made short.
As a result, the sleeve is buried in concrete after dismantling the formwork
At the time of making the drill thinly drilled three or four nail holes on each end
The hassle to penetrate and the sleeve do not come off under pressure
It wasn't easy to nail a bunch of nails to make sure it wasn't.

The present invention uses the action principle of the bolt nut to solve the above problems

Bolted sleeve tube body and corresponding nut-shaped coupling tube
Joining and proportioning the width of the wall to the existing PVC pipe for the secondary sleeve
Cut it and insert it into the sleeve tube body.
Hanging in the protruding hole of the main body and turning the coupling tube,
The sleeve is designed to stick to both sides of the formwork.

The material of the present invention is made of synthetic resin or iron, and the outer circumferential surface is made of thread (3).

On one side of the tube is a rib (4) having a hole for nailing in the direction perpendicular to the tube.

Bolted sleeve tube body 1 and protruding threaded body 3 of sleeve tube body 1

There is a female thread (5) to be combined with the secondary side made of conventional P V C tube

Attach the washer-shaped flange 6 perpendicular to the tube so that it can be in close contact with the sleeve 8

One side is made of a tube (7) of length that is easy to turn by hand during work

Composed of a coupling pipe (2) and the specific configuration action of the present invention, such as

4 is a cross-sectional view of the use state, and construction is finished.

The present invention cuts the conventional tube and drills three to four nail holes at an angle with a drill at both ends

Reduce labor cost in manufacturing sleeve by drilling hole

Even if only one nail is inserted into the formwork of a wall with an obstacle, the sleeve

As it can be closely adhered to the wall, it shortens the working time and casts concrete.

Not only can the construction defects such as location deviation due to the pressure of the city be reduced,

If you adjust the length of the auxiliary sleeve, even one standard product, regardless of the width of the wall

Not only construction is possible,
It can be used to reduce industrial waste by recycling waste bags.
There is also an effect.

Claims (1)

       Nail holes on one side of the bolt-shaped pipe with outer circumference       In the main body sleeve tube ribs protrude in a direction perpendicular to the tube,       A female thread is formed to engage with the thread, and one side is in contact with the auxiliary sleeve tube.       The coupling tube formed with a flange of the washer type is combined and has a larger diameter than the coupling tube.       The length is adjusted according to the width of the wall, and it is an auxiliary sleeve pipe inserted into the body sleeve pipe.       Wall through sleeve, characterized in that configured.
