Description

  The present invention relates to a new method for laying water / hot water and a drain pipe in a building drainage system.

  Conventionally, architectural drainage systems such as apartment houses and detached houses usually have a single drainage pipe (drainage horizontal pipe) for drainage from water-related appliances on each floor, such as kitchens and washstands, for drainage standpipe. It was common to join a thick drainage pipe, guide it to the junction joint with a gradient with respect to the standpipe, and join it on the same floor as the peripheral equipment. And in this junction part, it merges at right angle with respect to a vertical pipe, or it is made to merge while making it incline slightly diagonally, but this joint used the thing with a big capacity | capacitance, and especially the thing with a big horizontal cross-sectional area was required. . For this reason, the weight of the joint is heavy and expensive. In addition, a large space was required, and a considerable floor height was required to provide a gradient to the drainage horizontal pipe.

  The present inventor has improved the conventional technique and proposed a new technique in which the fluid flow in the drainage horizontal pipe is changed to a siphon flow. That is, the technical content is an architectural drainage system comprising a standing pipe penetrating each floor, an independent drainage horizontal pipe led from the water-equipment on each floor, and a joint directly connecting this to the standing pipe. The level is lowered from the level of the drainage floor slab, and a vertical velocity component is sufficiently imparted to the fluid in the drainage horizontal pipe, and then merged with the fluid in the vertical pipe (Patent Document 1).

JP 2002-121792 A

  In the above technique, water supply / hot water supply and drainage in each water supply apparatus are performed by independent horizontal pipes, and in particular, the drainage has a so-called ventilation resistance because the vertical velocity component is increased and merged with the fluid in the vertical pipe. It was significantly reduced. For this reason, the negative pressure generating action in the pipe is extremely reduced compared to the conventional construction drainage system. And the fluid in the drainage horizontal pipe may be a relatively thin pipe because it is a full flow due to the siphon phenomenon, and it is not necessary to provide a gradient toward the vertical pipe. Even so, drainage will be possible. For this reason, the height of the floor is not so much required, the living space is increased accordingly, and it is a perfect method for barrier free measures.

  The present invention intends to further improve the above-described proposed building drainage system. Specifically, a water supply pipe, a hot water supply pipe, and a drain pipe arranged on a floor slab are arranged for each one-water-use device. It tries to plumb together.

  The gist of the present invention is that a vertical pipe penetrating each floor, a horizontal drain pipe led from the water equipment on each floor, a junction joint for connecting the horizontal drain pipe to the vertical pipe, and a water-sealed trap on the horizontal drain pipe In a building drainage system that provides a siphon flow by storing fluid in a drainage horizontal pipe, at least one of the flexible water supply pipe, hot water supply pipe, and drainage horizontal pipe in a single water supply device is a restraining member. The drainage pipe laying method is characterized in that it is bundled with a pipe, and the drainage horizontal pipe may be bundled with a restraining member. Preferably, the rail member is fixed to the pipe surface and restrained. The water supply / drainage pipe bundled by a member is fitted into a rail part, and the restraining member may be a heat insulating material.

  The present invention is as described above, and the water supply pipe, the hot water supply pipe, and the drain pipe are all flexible pipes that are bundled together in a bundle of two to three with a predetermined interval. Or bundled all around. When bundled at a predetermined interval, these bundled pipes are wrapped and stored in a roll shape as they are, and then transported to the work site as they are. This will have a great effect on workability.

  As described above, the new construction drainage system by the present inventors has been further improved in terms of workability, and two or three pipes required for one watering device are grouped in advance. In addition, it is necessary to draw this out at the construction site one after another, and the necessary pipes can be piped as they are, and the floor can be piped without being arranged in four directions. It functions effectively. And according to this new system, it is not necessary to give a gradient to piping, and it is sufficient even if there is a slight reverse gradient in parallel to the piping surface.

  According to the system of the present invention, the piping route can be precisely defined in the minimum space in advance according to the intention of the design builder, and based on the design, for example, a mat-like flexible rail member that has been precut at the factory is developed. In addition, the construction is simply to insert a bundle of pipes that are connected to the peripheral equipment into the rail portion. Therefore, pipes can be accurately piped to the same location as long as any property is the same, and piping work can be completed with the same pipe configuration no matter who works at any time. Can be shortened to In addition, it is easy to handle during maintenance, such as troubleshooting, expansion / remodeling / updating construction, etc., and it has resource saving, labor saving, renewability, and economy. In this respect, it is needless to say that the sheath pipe method, which is a conventional construction technique, is not uniform, and the method of the present invention is superior to this.

  In a normal house model, there are at most 5 to 7 watering devices. As mentioned above, the water supply pipe and hot water supply pipe, and also the drainage horizontal pipe are brought together into the construction site as a roll. Is pulled out at the required length, fitted into the rail part, one end to the water supply port, hot water supply port and drainage port on the appliance side, the other end to the water supply and hot water supply header, and Piping work is completed by joining the other end of the drainage pipe to the drainage vertical pipe.

  Each pipe used here is a flexible pipe, for example, a resin pipe made of polybutene, a pipe made of (non-ferrous) metal, and its diameter is about 10 to 13 A for water supply and hot water supply pipes. The tube is about 20A.

  Although two to three pipe bodies to be applied to one device around the water are restrained by the restraining member, the restraining member is not particularly limited, and a flexible resin band is preferably used. In addition, the restraining member may be a resin extruded member having a fitting portion that restrains each tube, and may further be provided with heat insulation, for example, polystyrene or polyethylene. It can also be made of a foam material. Furthermore, the configuration of the restraining member is not particularly limited, and it is possible to integrate separate restraining members with hooks or the like.

  The rail member provided on the piping floor or the piping ceiling surface is not particularly limited in terms of material, but for example, a rail member made of polyvinyl chloride is used, which includes a bottom portion in contact with the floor and a predetermined portion based thereon. The rail portion is constituted by a flange portion that rises with an interval of, and is cut with a desired number of rail portions to be disposed on the floor surface as a rail member. The floor surface to be deployed is not limited to a normal floor surface, but it is also possible to deploy the rail portion downward on the surface constituting the ceiling. This rail member can also be a rail member having a large number of rail parts by connecting a small number of rails as basic members.

Hereinafter, the present invention will be described in more detail with reference to preferred embodiments.
FIG. 1 is an overall plan view showing the concept of the water / hot water supply and drainage pipe laying method of the present invention. In the figure, 1 is a drainage stack, and 2 is a water / hot water header, which is an example provided at a position close to both as a whole position. Numerals 3 and 4 indicate watering devices in the bath unit, 5 indicates a watering device in the toilet unit, 6 indicates a watering device in the kitchen, and 7 and 8 indicate other watering devices. Reference numeral 12 denotes a rail member, and reference numeral 13 denotes a bundle of pipes, which is a polybutene water supply pipe 13a, a hot water supply pipe 13b, and a drain pipe 13c bundled by a restraining member 14 (13). The water supply pipe 13a and the hot water supply pipe 13b have a diameter of 10A, and the drain pipe 13c has a diameter of 13A.

  For example, FIG. 2 shows the rail member 12 in the portion A, and FIG. 3 shows the rail member 12 in the portion B, for example. The rail member 12 includes a bottom 12a and a plurality of flanges 12b rising from the bottom 12a. The rail member 12 is a rail portion 12c into which a tube 13 bundled between the flanges 12b and 12b is fitted. In this example, the rail member 12 is made of vinyl chloride and has a sheet shape. For example, the rail member 12 in the A portion leaves the necessary number of the rail portions 12c in the portion, and the B portion. The rail member 12 is cut and disposed at each position.

  More specifically, a rail member 12 having a large number of rail portions 12c is formed in advance, and is cut by leaving an appropriate number of rail portions 12c. As shown in FIG. 4, a rail member 12 having a small number of rail portions 12c is formed, and a plurality of these members are connected to each other as necessary. It is also possible to obtain a rail member 12 having a large amount. In the illustrated example, a protrusion 12e is provided on one side and a hole 12f is provided on the other side at a position opposite to this, and the two are fitted and connected.

  In this example, the rail member 12 is provided continuously from the header 2. However, for example, the rail member 12 may be provided with a gap (L) as shown in FIG. Since these rail members may be additionally provided with water-related devices by a reform or the like, it is preferable to use a rail member provided with an extra rail portion in advance.

  FIG. 6 is a view showing the restraining member 14 and the bundled tube 13, and FIG. 7 is a front view. In the figure, a polybutene water supply pipe 13a, a hot water supply pipe 13b, and a drain pipe 13c are bundled by a band-shaped restraining member 14a made of polypropylene.

FIG. 8 shows a restraining member 14b obtained by extrusion molding. The extruded member is cut to an appropriate length to form a restraining member 14b, and each tube is placed in each of the storage portions 14b ₁ , 14b ₂ , 14b ₃ . Each tube is fitted. FIG. 9 shows a cross-sectional view when the tube bundle 13 is fitted into the rail portion 12 c of the rail member 12.

Figure 10 is another restraining member 14c and 11 are views which with a detained each tube, cut to length, is intended to fit the respective tube with a slit 14 _0. That is, although each pipe is restrained by the restraining member 14 with an interval of about 40 cm, it is of course not limited to this. In some cases, a long restraining member is used, and each pipe is placed in the storage portion. May be inserted.

FIG. 12 shows an example in which the entire restraining member 14d is composed of a heat insulating member. For example, the restraining member 14d is made of polyethylene foam and has slits 14 _{0 in the} storage portions 14d ₁ , 14d ₂ , 14d _3.
And each tube is accommodated therethrough.

13 and 14 show other restraining members 14e and 14f, which restrain the water supply pipe 13a and the hot water supply pipe 13b with heat insulating restraining members 14e ₁ and 14f ₁ and the drain pipe 13c with heat insulation restraint. Member 14e ₂
14f ₂ , FIG. 13 is integrated with a double-sided tape, and FIG. 14 is an uneven member 14f ₃ , 14f _4.
Are integrated with each other.

  FIG. 15 shows the relationship between the tube bundle 13, the header 2, the watering device 6, the drainage stack 1, and the junction joint 1A. That is, one end of the water supply pipe 13 a and the hot water supply pipe 13 b is attached to the header 2, and the other end is attached to the water-surrounding device 6. One end of the drain pipe 13c is extended to the junction joint 1A of the vertical pipe, where it joins the drainage in the vertical pipe 1, and the other end is connected to the drain port of the watering device 6. The drainage pipe 13c basically does not join with other drainage pipes until it joins in the vertical pipe 1, and reaches the vertical pipe 1 independently from each water-related device.

  The bent pipe 13d is preferably disposed on the distal end side of the drain pipe (horizontal pipe) 13c. For this reason, the drain pipe (horizontal pipe) 13c is usually in a state where the drainage remains, and the amount of remaining drainage increases. When the height of the bent pipe 13d is exceeded, the water suddenly flows out, and the water in the drain pipe 13c is drained by a so-called siphon phenomenon. The drainage of the water in the drainage pipe can be made relatively small in diameter by using the siphon phenomenon, and the troublesome work of providing a gradient to the drainage pipe becomes unnecessary. Of course, drainage is possible using this siphon flow even with a slight reverse gradient, and the drainage function is not lost even when the drainage pipes intersect.

  FIG. 16 is an overall plan view showing the concept of the water / hot water supply and drainage pipe laying method of another example of the present invention. In the figure, the drainage stack 1 and the water / hot water header 2 are examples provided almost on the opposite side as a whole. Therefore, only the water supply pipe 13a and the hot water supply pipe 13b are restrained in advance by the restraining member, and the tube bundle 13 bundled thereby is fitted into the rail member 12. On the other hand, the drain pipe 13c is fitted into the rail portion 12c of the rail member 12 alone.

  FIG. 17 shows a tube bundle 13 used in the case of FIG. 16, and it goes without saying that the tube bundle 13 shown in FIGS. 13 and 14 can also be adopted.

  In the present invention, a water supply pipe, a hot water supply pipe and a drain pipe are bundled and transported and stored in advance, and this is used as it is at the time of piping at a construction site. Since it can be connected to air conditioning equipment piping etc., it is a construction method with a high degree of completeness in building technology as a more promising building system integrated part.
