Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe connection unit for an air conditioner that quickly and surely and easily connects a cold / hot water pipe to be connected to the air conditioner when the air conditioner is installed in a room such as a building. It is a thing.

[0002]

[Prior art]

 Conventionally, for example, floor-mounted fan coils have been installed in rooms such as buildings for air conditioning and heating, and at the same time, pipe connection work has been carried out to supply a large number of hot and cold water to the air conditioners. However, since it is installed and fixed in a predetermined place, it is difficult to connect it at the proper position due to insufficient connection position of the water flow pipe drain drain pipe, etc. Was required, and complicated rework work was required.

[0003]

[Problems to be solved by the device]

 Furthermore, since heat insulation and heat dissipation prevention are absolute conditions during the installation of the fan coil, heat insulation work is also performed in parallel with the pipe connection work, but it is extremely difficult to carry out the work work in a narrow space that normally takes place. In addition, it is not easy to ensure quality, and since most of the above construction time is after the completion of air conditioner installation, there was a problem in securing the process. The present invention is intended to solve the above-mentioned problems at the root, and the piping connection and heat insulation work at the time of installing the air conditioner are integrated, and the number of parts used is small, and the labor is not required. It aims to provide labor-saving labor-saving methods whose main purpose is to save money.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned problems, the present invention proposes that several pipes 1 for feeding cold / hot water or the like, in which a heat insulating material 2 made of an appropriate material is coated on the pipe surface, are arranged in the axial direction, and several pipes are arranged in parallel. The appropriate positions of the pipes 1, 1, 1 are fastened and held by the fasteners 4 at regular intervals, and the backfill plate 3 is fitted and provided in the intermediate portion of the pipes 1, 1, 1. The structure of the connecting pipe in which the respective pipes 1, 1, 1 are integrally formed is featured. In addition, by forming the material of the heat insulating material 2 to be covered on the surface of the connecting pipe 1, 1, 1 as described in claim 2 by using a material such as rubber material or urethane foam which has good sound absorption and moisture resistance. It goes without saying that it exhibits a more effective function.

[0005]

[Action]

 The pipe connecting unit according to the present invention is formed by the above-mentioned mechanism. When the fan coil unit A is installed at a predetermined position on the floor as shown in Fig. 3, the concrete layer on the installation floor is preliminarily set. The entire unit for connecting a pipe of the present invention is inserted and supported in a pipe supporting hole C formed by drilling in B, and then each connection port 1a at the end of the pipe 1 is connected to a cold / hot water pipe d of a heat exchange coil c on the unit A main body side. , E and drain pan g of drain pan f, respectively. In such a state, the construction is completed by filling the voids of the pipe support holes C with cement D to refill the space and fixing the pipes 1 in the holes. Since the backfilling plates 3 are integrally and continuously attached at appropriate positions below, the backfilling plates 3 naturally cover the bottom of the opening of the support hole C when the pipe is supported, and thus the cement D is filled. In addition, it is possible to prevent falling downwards in advance and obtain a reliable filling material, and it is also possible to omit various work such as cleaning after the work is completed.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Several pipes 1 for feeding cold and hot water, which are formed by covering a pipe surface with a heat insulating material 2 to an appropriate thickness, are arranged in parallel in the axial direction. A number of pipes 1, 1, 1 are fastened and held with fasteners 4 at fixed intervals, and a circular metal or synthetic resin plate is placed at an appropriate place in the middle of the pipes 1, 1, 1 described above. The above-mentioned backfill plate 3 is integrally fitted to form a unit for pipe connection. In order to make the number of pipes equal to the number of pipes on the connection side of the main body, a large number of pipes are integrated. There is also a case to be attached to.

Although any material can be used as the material of the heat insulating material 2, for example, by using a material having good sound absorbing and moisture proof properties such as rubber material or urethane foam, it is possible to have a function described later. obtain.

Further, although detailed concrete examples thereof are omitted in the drawings, the respective fastening portions 4a of the fastening fittings 4 of the respective pipes 1, 1, 1 are provided with fastening fixing portions such as long holes and screws, for example. By adjusting the expansion and contraction of the pipes, it is possible to change the holding interval dimension of each pipe 1, 1, 1 to an arbitrary interval and to easily find a pipe connection unit that adapts to the pipe interval on the main body side on site. is there. Although the above description of the action column and the examples exemplify the case of the floor-standing fan coil, it goes without saying that the piping structure can be widely used for other various air conditioners.

[Effect of device]

 As described above, the pipe connecting unit in the air conditioner according to the present invention has a plurality of heat insulating materials 2 provided on the pipe surface of the cold / hot water supply pipe 1 and having an appropriate thickness, which are aligned in the axial direction. It is suitable for mass production because the several fittings are fastened and held by fasteners 4 at fixed intervals and the backfilling plate 3 is integrally mounted on the pipe 1 as described above. Not only is it inexpensive, but it also has the various effects described below. When installing the fan coil, the piping work can be carried out accurately and easily at the proper position on site, significantly improving the work efficiency and eliminating the need for rework work that was required in the past. Since the heat insulating material is applied to each pipe in advance without having to carry out work such as heat insulation between the fan coils, it is possible to easily and reliably carry out construction in any narrow space. did. A wide variety of complicated works such as hot and cold water and drains were performed all at once, and in the past, consistently different works for each industry such as ceiling piping as well as piping to the top of the floor finish surface, water pressure test and heat insulation work were performed. The labor management in the field is very easy and human resources can be greatly saved. Backfilling work around the floor penetration sleeve can be done in an orderly and reliable manner.Especially because part of the pipe is provided with a backfilling plate, excess filling material may be generated at the time of construction. It is possible to refill very economically without fail, and it is possible to firmly solidify the filling material in the hole and simultaneously fix a large number of pipes at the same time, and even if the excess is left, the lower surface of the pipe insertion hole is completely covered from below. However, the cleaning work on the ceiling, which is so-called difficult, is omitted, and the design feeling on the ceiling surface is excellent. Further, the heat insulating material to be covered on the pipe surface according to claim 2 can be generated in the machine as well as the heat insulating effect by using a material having good sound absorbing and moisture proofing such as rubber material or urethane foam. The vibration noise prevents the fear of being transmitted through the pipe to the periphery of the pipe, and also has a waterproof function.
