Abstract

<P>PROBLEM TO BE SOLVED: To supply clean, rust-free water for a long period of time by simple work and perform hot water heating durable for long-term use by arranging pipes in partition walls through the application of this technique. <P>SOLUTION: A cross-linked polyethylene pipe is arranged in a pipe 20 arranged in a building to feed water through the cross-linked polyethylene pipe. The cross-linked polyethylene pipe is resistant to bending deformation, and its physical properties do not change even if high-temperature water is passed. Since the cross-linked polyethylene pipe is light in weight and easily handled, it is possible to arrange the cross-linked polyethylene pipe in the pipe by sending the cross-linked polyethylene pipe from one end of various pipes such as a water pipe, a hot-water supply pipe, and pipings for heating. Since the cross-linked polyethylene pipe does not rust, it is possible to assure water quality for a long period of time. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to the structure of water supply or circulation in buildings.

A building is provided with various pipes (water pipes) for supplying or circulating water. They are so-called water pipes (water supply pipes), drain pipes, hot water supply pipes, heating pipes for circulating heated water, and the like. Conventionally, these tubes use metal circular tubes.
None

  As is widely known, building pipes provided for the passage of water cause rust due to aging. However, for example, even if the use as drinking water or bath water becomes very severe, it is often used as it is. This is because the construction cost for exchanging the pipes is high, and due to various reasons such as real estate value, there are not a few residents who think that it is more advantageous to renovate the whole building rather than exchanging the pipes. It becomes a serious problem in condominiums and apartments.

  Therefore, an object of the present invention is to always supply clean water without rust by a simple operation. The same applies not only to the water supply but also to the supply of hot water and the supply of water for heating (circulation use, etc.).

  In order to achieve the above-mentioned object, the water pipe structure of a building according to claim 1 arranges a cross-linked polyethylene pipe inside the pipe arranged in the building, and sends water through the cross-linked polyethylene pipe.

  The cross-linked polyethylene pipe has a thickness sufficient to withstand sufficient water pressure, but also withstands bending deformation necessary for construction, and hardly undergoes deterioration or changes in physical properties even through high-temperature water. It is lightweight and easy to handle. For this reason, cross-linked polyethylene pipes are fed from the ends of various pipes such as water pipes, hot water pipes and heating pipes installed in buildings, regardless of whether they are existing or new. Can be set.

  If water is supplied or circulated through the cross-linked polyethylene pipe with the cross-linked polyethylene pipe loaded in the pipe, even if the pipe has already deteriorated over time, it is the same as replacing the pipe. Clean water without rust can be supplied to living rooms and bathrooms. Even if decades have passed and it becomes necessary to replace the cross-linked polyethylene pipe due to scale (chlorine or lime components, etc.) contained in tap water, it is easy to remove it and install a new cross-linked polyethylene pipe. Because there is no need to touch the walls, floors, or ceiling of the building, construction costs during maintenance can be kept extremely low.

  Claim 2 relates to a so-called water pipe (supply pipe for clean water), which is a technique for utilizing a resin pipe. Conventional water pipes installed in buildings are metal pipes. The invention according to claim 1 can be applied to an existing metal pipe, but when applied to a new building, it may be advantageous to use a resin pipe. This is because the pipe is excellent in terms of cost, workability, weight, and the like.

  Claim 3 is a technique related to heating of a living room. A pipe is provided inside the outer wall or partition wall, and heated water is supplied from a hot water supply device to a cross-linked polyethylene pipe provided therein.

  Conventionally, when hot water is used for heating in a house, a pipe is provided under the floor and the hot water is circulated and supplied to the pipe. This is so-called floor heating. In the case of floor heating, even if the pipes are maintained, there is no need to mess with the wall plate or the partition wall on the outside wall side. However, in the conventional system that directly circulates high-temperature water into the metal pipe, heating using an outer wall or a partition wall is not possible in consideration of maintenance.

  On the other hand, according to the structure according to claim 3, since it is easy to dispose and replace the cross-linked polyethylene pipe inserted into the pipe, wall heating using warm water is realized at a reasonable construction cost. I can do it. Wall heating using hot water has a much higher heating effect than wall heating using heated air. Also, unlike floor heating using hot water, it is possible to simultaneously heat both the left and right rooms on each floor using a single pipe, so the pipe length of the pipe is longer than when realizing the same effect with floor heating. It can be surely shortened.

  According to the water pipe structure of the present invention, it is possible to always supply clean water with less deterioration over time of the pipe as compared with the case where water is passed through the pipe. It is very easy to install and replace the cross-linked polyethylene pipe inside the pipe. If a cross-linked polyethylene pipe is provided inside the pipe to supply water (including circulation supply), it is possible to provide wall heating inside the wall and send high-temperature water to the cross-linked polyethylene pipe. Wall heating with high heating effect can be realized without worrying about the construction cost during maintenance.

  FIG. 1 and FIG. 2 show a case where a pipe 20 is provided on a partition wall 10 in a building and a cross-linked polyethylene pipe is arranged inside the pipe 20 when applied to circulating supply of high-temperature water for heating. This is just an example. 31 is a room on the first floor, and 32 is a room on the second floor.

  In order to circulate and supply heated water from a boiler apparatus (not shown), the pipe 20 is, for example, a metal round pipe, and a crosslinked polyethylene pipe 22 is loaded therein as shown in FIG. . Hot water is fed into the cross-linked polyethylene pipe 22.

  For example, the pipe 20 is arranged in the vertical direction (vertical direction) from the floor of the first floor of the building to reach the vicinity of the ceiling of the uppermost floor (for example, the second floor), and the horizontal direction so that the entire partition wall 10 is warmed. In addition, a plurality of pipes 20 are arranged in parallel in the vertical direction, and the upper ends and the lower ends of the pipes 20 are connected to each other by a header (connecting pipe) 23 so as to form one continuous pipe. Reference numeral 24 denotes a hot water supply pipe for supplying hot water from the boiler device to the cross-linked polyethylene pipe 22 of the pipe 20 at the left or right end.

  The partition wall 10 is preferably configured as a reinforced concrete wall on at least one side. In FIG. 1, reference numeral 12 denotes a reinforcing bar disposed inside the partition wall 10. The reason why the partition wall 10 in which the pipe 20 is disposed is made of reinforced concrete is that the heat released from the pipe 20 is accumulated in the concrete so as to always give radiant heat (heat ray effect) to the living room. It is desirable that the inner space of the partition wall 10 in which the pipe 20 is disposed has a gap of, for example, a width of about 10 cm so that the pipe 20 does not contact the concrete wall (10). This is to prevent deterioration.

  Radiant heat has a large permeability in the air and has the effect of removing moisture and suppressing the generation of mold. For this reason, the heat of the high temperature water discharged from the pipe 20 is once stored in the partition wall 10 made of reinforced concrete, and then released as radiant heat, thereby preventing the occurrence of condensation and mold in the living room.

  In the case where the partition wall 10 is made of concrete, for example, concrete is placed on a mold to make one wall, a pipe 20 is disposed, a crosslinked polyethylene pipe 22 is connected by a header 23, and the other wall is reinforced concrete. Build using the board made of. Reinforced concrete boards may be used on both sides.

  For the pipe 20, for example, a commonly used metal pipe for water supply can be used. The tube 20 has an outer diameter of 48.6 mm and an inner diameter of 46 mm, for example, and a crosslinked polyethylene pipe 22 having an outer diameter of 17 mm and an inner diameter of 13 mm is loaded therein. Since the cross-linked polyethylene pipe 22 is flexible, curved, and lightweight, it can be fed from the end of the pipe 20 and sent to the other end of the pipe 20, but in this embodiment, in the longitudinal direction The cross-linked polyethylene pipes 22 are individually arranged on the pipes 20 arranged in the pipes, and the ends of the cross-linked polyethylene pipes 22 are connected to each other by a header 23. This is because in the case of a new construction, it is easier to dispose the crosslinked polyethylene pipe 22 and the subsequent maintenance is easier. As the high-density crosslinked polyethylene pipe 22, for example, an Excel pipe (trade name; Mitsubishi Chemical Corporation) can be used. Excellent pressure resistance and heat resistance, as well as corrosion resistance and chemical resistance.

  In the case of such wall heating using hot water, it is desirable to prevent cold air from under the floor. For example, as shown in FIGS. 1 and 2, a plurality of heat storage transfer pipes 40 are driven under the floor so that the geothermal heat in the floor of the building can be transmitted to the underfloor space 41 at all times. Even in the severe winter season in cold regions, the underground under the building is relatively warm due to the effect of geothermal heat and cool in the summer, so it is a preferable structure for adjusting the temperature of the living room. 44 is slab concrete for the first floor, 45 is slab concrete for the second floor, and 46 is foamed concrete for heat insulation and sound insulation disposed on the slab concrete 44, 45 of each floor. The floor finish board is omitted. 48 is the foundation concrete of a building.

  Therefore, according to this structure, by supplying the high temperature water from the boiler device to the pipe 20 inside the partition wall 10, the concrete constituting the partition wall 10 is temporarily stored with heat and the stored heat is released. Therefore, it is possible to always supply a warmth to the living room. Heating by releasing so-called radiant heat is stable and soft heating with little temperature difference even at midnight, unlike heating by the heating power of a stove or hot air of an electric heater. Excessive heating is not too hot, and the room temperature is always stable, so an environment that is friendly to the elderly and infants can be realized. In general, when heating a cold district, the room tends to become hot when the stove is turned on, and the room becomes cold when the stove is turned off. The same can be achieved with floor heating using hot water, but floor heating using hot water requires piping on the floor of each floor, which inevitably increases the piping length and increases construction costs. is there.

  In the case of the present invention, the cross-linked polyethylene pipe 22 is disposed inside the pipe 20, so there is no problem of deterioration (particularly rusting) of the pipe 20. For this reason, even when it becomes necessary to replace the crosslinked polyethylene pipe 22 with a new one, it is not necessary to break the building (partition wall 10). It is only necessary to replace the cross-linked polyethylene pipe 22 simply while leaving the pipe 20 as it is.

  The water supply pipe is the same. Cross-linked polyethylene pipes can also be inserted into existing water supply pipes, so water pipes that have already become old and rusted are the same as renewed water pipes with easy construction. It can have an effect. When applied to a new building, the water pipe need not be a metal pipe but may be a resin pipe.

  In addition, the water pipe structure concerning this invention is not limited to the thing of the said embodiment. For example, the partition wall 10 in which the pipe 20 is arranged may use a concrete block. This is because even if the partition wall 10 is made using a concrete block, the radiation of the pipe 20 can be stored and radiant heat can be always supplied to the living room.

  There is little need to dispose the tube 20 on the outer wall. This is because if the pipe 20 is arranged on the partition wall 10 and hot water is supplied, the corner room and the room on the outer wall side are also heated.

  When circulating hot water to the crosslinked polyethylene pipe 22, an antifreeze solution may be used.

  A plurality of pipes 20 may be arranged in the horizontal direction, but there is no temperature difference between the upper floor and the lower floor when a plurality of the vertical pipes 20 are arranged. When long pipes that are bent in the horizontal direction are arranged up and down, the temperature of the first pipe that supplies hot water becomes high, and the temperature of the hot water decreases as it goes downstream. However, the temperature drop of hot water is not severe. The temperature difference between the supply start point and the supply completion point is, for example, about 10 ° C. The hot water supplied at 70 ° C. is about 60 ° C. at the completion point, and if it is a low-rise house, it can withstand practical use even if the pipe 20 is placed horizontally.

  The heat source of the high-temperature water supplied to the crosslinked polyethylene pipe 22 is not necessarily limited to the boiler device. This is because natural hot water such as hot springs may be used.
