Description

Buried pipe assembly {BURIED PIPE ASSEMBLY}

The present invention relates to a buried pipe assembly to be installed buried in a building.

It should be noted that the content described in this section merely provides background information on the present invention and does not constitute the prior art.

In general, a copper pipe is used for the buried pipe installed in an apartment house, and to connect the air conditioner and the buried box, the copper pipe connecting the copper pipe and the air conditioner in the buried box is welded and connected.

Therefore, for the welding of the copper tube, the help of a professional technician is required, and the risk of fire due to welding is high.

In order to relocate the air conditioner, since the copper tube in the buried box is installed by welding, the copper tube must be cut to transfer the air conditioner. Unexpected problems often arise.

Therefore, in this case, since it is necessary to dismantle the wall and expose the copper tube, the construction is very difficult and the installation takes a lot of time and money.

In addition, copper pipe is expensive and price fluctuation is large, so the stability of the market price is low, and its strength is also lower than that of the existing stainless steel (STS steel). There are also problems that occur, which need to be addressed.

Claims (10)

a buried box that is embedded in a building and provides a connection part with air conditioning equipment;
a pipe module whose end is connected to the embedding box, and in which a stainless steel embedding pipe, cable, and filler are integrally produced inside a protective pipe embedded in a building; and,
A buried pipe assembly comprising a; a pipe connecting device installed in the buried box and connecting the buried pipe and a facility pipe of the air conditioning equipment.
According to claim 1, wherein the pipe connection device,
It is configured in a split type including a first connector and a second connector, wherein the first connector and the second connector are screwed together,
The buried pipe is inserted and fixed to the first connector by a one-touch method, and the facility pipe is inserted and fixed to the second connector by a one-touch method.
According to claim 2, wherein the buried box,
a first buried box to which one end of the pipe module is connected and which provides a connection part to an outdoor unit of the air conditioning equipment; and,
and a second buried box to which the other end of the pipe module is connected and which provides a connection part to an indoor unit of the air conditioning equipment;
The first connector is installed in the outdoor unit and the indoor unit,
A facility pipe is installed between the first connector and the second connector of the pipe connector.
According to claim 1, wherein the pipe connection device,
a first connector in which a first one-touch portion is formed on one side of which a pipe is inserted and fixed in a one-touch manner, and a first threaded portion is formed on the other side;
a second connector in which a second one-touch part is formed on one side of which a pipe is inserted and fixed in a one-touch manner, and a second threaded part coupled to the first threaded part is formed on the other side; and,
A buried pipe assembly including a; a sealing connector for sealing a double structure between the first connector and the second connector.
According to claim 4, The first connector,
a first one-touch unit to which the buried pipe is inserted and fixed in a one-touch manner;
a first connector part extending from the first one-touch part and having an enlarged diameter flange formed at an end thereof; and,
Includes; a first screw portion that is installed to be movable and rotatable in the longitudinal direction on the first connection pipe portion;
The sealing connector is a buried pipe assembly installed so as to form a pair on the front and rear surfaces of the longitudinal direction of the enlarged diameter flange.
The method of claim 5, wherein the first connecting pipe portion,
The embedding pipe assembly further comprising a; a bending ring member extending in a bending direction from the enlarged diameter flange and installed to surround the second sealing connector.
According to claim 5, The sealing connector,
a first sealing connector installed between the longitudinal front surface of the enlarged diameter flange and the second screw part; and,
A second sealing connector installed between the longitudinal rear surface of the diameter-expanding flange and the first screw portion; includes,
The first sealing connector,
A buried pipe assembly, characterized in that it is disposed between a first sealing groove formed internally in the enlarged diameter flange, and a second sealing groove internally formed in the front end of the second screw portion.
According to claim 4, The second connector,
a second one-touch unit to which the facility pipe is inserted and fixed in a one-touch manner;
a second connector part extending from the second one-touch part; and,
A buried pipe assembly including a; a second screw part installed on the second connection pipe part and fastened to the first screw part.
The method of claim 4, wherein the one-touch unit,
One-touch body into which the pipe is inserted;
It includes; a pressure fixing member installed inside the one-touch body and pressurizing and fixing the pipe inserted into the one-touch body;
The pressure fixing member,
Temporary member disposed on the inlet side of the one-touch body and temporarily fixed by pressing the pipe; and,
Disposed at the rear of the temporary member, the main fixing member by pressing the pipe with a greater force than the temporary member; a buried pipe assembly comprising a.
The method of claim 9, wherein the temporary member,
A temporarily fixed wedge protruding in the direction of the central axis of the one-touch body to a first set height (H1) is formed so as to be in close contact with the outer circumferential surface of the pipe,
This fixed member is
An embedded pipe assembly in which a main fixed wedge protruding to a second set height (H2) more protruding in the central axis direction of the one-touch body than the first set height is formed so as to be in close contact with the outer circumferential surface of the pipe.
