Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pipe joint for piping for air conditioning equipment that is piped through the floor or wall of a building.

Generally, in buildings made of reinforced concrete and steel,
Inlet pipes for hot water, etc. of air conditioning equipment that penetrate the floor or walls,
The piping work for the water outlet pipe and drain pipe will be carried out in parallel with the construction of the structure as shown below, similar to other piping work.

First, a long pipe tube called a paper tube is cut according to the thickness of the concrete to insert the piping sleeve into the desired position of the floor or wall, and this is nailed into position. Perform fixation. Next, concrete is poured. and,
Remove the pipe tube and perform piping work.

However, when pipe tubes are conventionally used, the nails are fixed by construction on site, so it is virtually impossible to install them in the desired position, and the fixed positions are uneven. When concrete is placed, the ejecting force from the pressure pump or when moving the pressure hose hits the paper tube, causing the tube to move or tilt, making it difficult to carry out lifting work after removing it. There are problems such as the need for air conditioning equipment,
There are disadvantages in that the water inlet pipe, water outlet pipe, and drain pipe cannot be arranged at desired positions or intervals, and the arrangement of the pipes exposed indoors becomes irregular. Moreover, after piping is completed, not only is it necessary to backfill the gap between the pipe and the piping sleeve with mortar, which is extremely difficult and time-consuming work, but this area is classified as a fire prevention zone under the Fire Service Act, and is generally not It is well known that, because it is hidden by ceilings, etc., if sufficient backfilling is not done and a fire breaks out, toxic gases may leak out and cause more damage than expected. It is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pipe joint for air conditioning equipment that eliminates the above-mentioned drawbacks.

Next, one embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In the figure, C indicates a concrete slab of an arbitrary floor, and F is
This is the finished floor of the upper surface of leveled mortar M.

1.2 or 3 is an inlet pipe P-1, an outlet pipe P-2, or a drain pipe P- connected to an air conditioner (not shown).
3, each of which is formed in a substantially cylindrical shape, and each upper end is provided with the water inlet pipe P-1,
Upper connection part 12.22 with one internal thread 11.21.31 for connecting water outlet pipe P-2 or drain pipe P-3
．． 32, and each lower end has an upper connecting portion 12.32.
Similar to 22.32, each lower connection part 14 has one internal thread 13.23.33 for connecting a container pipe.
．． 24.34, and the nails are provided with small holes in the vertical direction in order to keep the level of the lower end surface constant and nail to the shape (not shown) on the side of each lower edge. This is the state that remains after the removal of.

Then, the inlet pipe P-1, the outlet pipe P-2, and the drain pipe p
-3, each pipe joint 1.2.3 is integrally connected to each other via an aggregate 4.5 at its side in correspondence with the piping spacing of the air conditioning equipment to be connected. ing.

The pipe fitting for air conditioning equipment of this embodiment having the configuration described above does not require the conventional method of neatly attaching a pipe tube to form a piping sleeve, and it also eliminates the need for construction. Depending on the conditions, the three integrated pipe joints can be fixed by direct nailing, etc., so needless to say, there is no need to remove the pipe tube, chisel the pipe sleeve, and connect the pipes. This eliminates the need for backfilling the gap between the sleeve and the sleeve, and can effectively prevent piping from becoming uneven.

Next, a second embodiment of the present invention will be explained with reference to FIGS. Since this can be said to be a modification, we will mainly discuss the differences.

That is, the pipe joint 1.2.3 is formed into a substantially cylindrical shape as in the first embodiment, but the height thereof is lower than the height of the floor made of concrete slab C or the like. . Therefore, a short pipe SP of a required length to which a socket S is connected is screwed to the upper connection portion of each pipe joint 1.2.3.

In addition, a small hole 45 is formed in the vertical direction on the side of the lower edge of the lower connection part of the pipe joint 1.2.3 in order to maintain the level of the lower end surface constant and nail it to the shape. A collar 46, which is formed into a rectangular shape on a plane, is integrally provided and is connected to the pipe fitting 1.2.3 at the same time.

Therefore, this embodiment also has the same effect as the first embodiment, but it can be said that it is particularly suitable for integrally connecting pipe joints when the piping pitch of each pipe joint is small. be.

The embodiments of the present invention have been described above, but these are as follows:
In each case, the pipe joints 1, 2, and 3 are arranged in two straight lines on a plane, but of course, the arrangement is not limited to this, and they may be arranged in a triangular shape depending on the use. Also,
It is also conceivable that the upper connection part or the lower connection part of each pipe joint may be connected by a plug-in type or the like via a rubber seal, in addition to a screw connection.

In short, the pipe joint for air conditioning equipment of the present invention is
At the side of each pipe joint for water inlet, water outlet, and drain, which is formed into a substantially cylindrical shape with pipe connection parts at the upper and lower ends, it is connected in one piece and the level of the lower end surface is kept constant. The device is characterized in that a collar is provided protruding from the side of the lower edge.

Therefore, by using the pipe joint □ for piping for air conditioning equipment of the present invention, there is no need to form a piping sleeve by neatly attaching a pipe tube, which was required in the conventional case. ,
Although its structure is extremely simple, it does not require extremely laborious and meaningless work such as removing the pipe tube, chiseling the pipe sleeve, and backfilling the gap between the pipe and the pipe sleeve. First, it has many effects.
