Abstract

<P>PROBLEM TO BE SOLVED: To improve a problem in a conventional hot water floor heating system that when laying one seamless continuous flexible hot water pipe in a pipe groove formed on the upper surface of a hot water mat in four parallel lines or more while turning down flush with the upper surface of the hot water mat, the average laying interval of the hot water pipe at a straight part is determined depending on the allowable minimum rotating diameter of the hot water pipe, and a necessary heating value cannot be ensured. <P>SOLUTION: In the hot water floor heating system for a bathroom washing place, the thickness of the hot water mat is set two times the diameter of the hot water pipe so that bank raising of floor can be also performed, and the pipe groove at an intersection for intersecting pipe grooves on the surface of the hot water mat is deepened to vertically cross hot water pipes by the two intersecting grooves, whereby the hot water pipe of the straight part can be laid flush with the upper surface of the hot water mat. Consequently, the laying density of the hot water pipe is doubled, and heat generation necessary for floor heating can be ensured. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a hot water mat for a hot water floor heating system, and is intended to ensure a necessary heat generation amount for floor heating, and is particularly effective in a bathroom.

  Conventionally, floor heating systems for indoors, particularly bathrooms, include floor heating methods in which hot water pipes or electric heating elements are embedded in floor mortar and the surface is finished with ceramic tiles. Since heat is transferred to the material, the heat generation efficiency is poor, the time until the temperature rises is long, and the running cost is high. Moreover, the construction time from placing the mortar to drying was long.

  The conventional hot water type floor heating system, in which a single continuous flexible hot water pipe is laid in the pipe groove formed on the upper surface of the hot water mat, there is a risk of water leakage at the part laid on the hot water mat. Although the time to temperature rise is short and the workability is good, as shown in Fig. 10, the rotating diameter of the hot water pipe to be used is specified by the hot water pipe manufacturer in the pipe groove shape of the conventional hot water mat curve part. Therefore, the laying interval of the hot water pipes arranged in parallel with the straight part of the hot water mat is also restricted by the minimum rotational diameter of the curved part, and the laying density of the hot water pipe that can be laid in a certain area is also restricted. . Therefore, in the case of a floor with a narrow area of about 800mm in width, such as a bathroom washing place in a general house, when a hot water pipe with a minimum rotation diameter of 100mm is used, the interval between the hot water pipes in the straight section However, there is a problem that the temperature unevenness and the heat generation amount are low simply by arranging six to seven hot water pipes in parallel at an average interval of 100 mm. (Patent Document 1)

  Therefore, the hot water pipe is used only for the straight part, and the curved part uses a substantially U-shaped metal joint processed to a diameter shorter than the minimum rotation diameter of the hot water pipe. Although there is a method of reducing the laying interval of the hot water pipes in the part, if metal joints are used for all the curved parts, there are problems that the cost increases and the labor of construction increases.

  Furthermore, it is possible to cross the hot water pipe in the gap by opening the hot water pipe to the gap between the floor joists without using the hot water mat in the curved part. The amount of heat generated in the bathroom decreased, and there was a problem in using it for the floor heating system in the bathroom of the bathroom without using joists. (Utility model document 1)

  In terms of construction, the bathroom floor is required to be waterproof, so fixing the hot water mat to the bathroom floor with nails or screws may cause water leakage. To avoid this, use nails or screws. It was necessary to prevent the hot water mat from being lifted with an adhesive without using.

  In a hot water type floor heating system in the bathroom, when laying a single continuous flexible hot water pipe in the pipe groove on the upper surface of the hot water mat, in order to increase the heat generation, It was necessary to increase the calorific value by increasing the laying density of the hot water pipes per area by reducing the laying interval of the hot water pipes as much as possible, increasing the number of times the hot water pipes were folded at the curved portion. However, if the pipe is bent below the allowable diameter dimension specified by the manufacturer of the hot water pipe, the pipe will bend and the liquid in the pipe may be blocked or the pipe may be damaged. There was a limit to increasing the laying density of flexible hot water pipes.

  It is necessary to avoid fixing the mat with nails or screws in order to prevent accidental drilling of the laid hot water pipe at the time of construction. In addition, in order to ensure the waterproof property of the bathroom floor, it is necessary to fix the hot water mat more firmly using an adhesive without fixing the hot water mat with nails or screws. In particular, in the case of a unit bath floor, fixing to the floor with a screw has a high risk of water leakage.

  Conventionally, a hot water floor heating system using a single continuous flexible hot water pipe is a renovation, etc., and it is necessary to lay using the floor structure of an existing room of an existing house. It was necessary to reduce the thickness of the hot water mat. However, in the present invention, in order to achieve the above-mentioned problem, the purpose of the present invention is to lay a hot water type floor heating system that also serves as a floor raising material in a bathroom washing place, and as a raising material for a bathroom washing place floor in a hot water mat. This also relates to the shape of the pipe groove on the upper surface of the hot water mat, which has a system configuration that does not cause any trouble even if the thickness of the hot water mat is more than twice that of the hot water pipe.

  As a result, by using the hot water mat 1a according to claim 1 of the present invention for the curved portion, the single continuous hot water pipe 3 that is laid on the hot water mat 1 is connected to the outgoing path. When laying is started from the pipe groove, the hot water pipe 3b in the return path crosses and overlaps with the hot water pipe 3a in the forward path laid at the intersection portion 2a of the curved portion of the hot water mat. The outward hot water pipe 3a sinks into the intersection 2a of the pipe groove of the curved hot water mat 1a formed deeply with a gradient around the intersection 2a of the curved portion of the hot water mat, and the hot water pipe 3b of the return path The pipe groove 2 of the mat 1 is smoothly laid with the upper surface of the hot water mat.

  Thus, even when the hot water pipes 3 are folded back so that four or more of the hot water mat straight portions 1b are arranged in parallel, by using a plurality of the hot water mats 1a of claim 1, the average of the hot water pipes 3 in the straight portion The laying interval is half the minimum rotation diameter of the hot water pipe 3, the laying density of the hot water pipe 3 is doubled, and the heat generation amount per area is increased.

  Further, at the intersection 2a of the hot water pipes, the hot water pipe 3a laid in the outward path sinks under the hot water pipe 3b in the return path, so that the heat generation efficiency is reduced, but the hot water pipes 3b laid in the return path overlap. Therefore, the hot water pipe 3b laid on the return path is in close contact with the surface finishing material (for example, ceramic tiles and stones) with a metal tape or a metal plate for heat diffusion in between, so the heat generation at the intersection is reduced. Are very few.

  The hot water mat 1 of the curved portion and the straight portion is bonded to the floor of the bathroom, and the hot water mat 1 has a diameter of the bottom surface of the hot water mat 1 as described in claim 3 of the present invention. A plurality of mortar-shaped inclined openings 4 penetrate through, and the adhesive is solidified in a wedge shape in the openings 4 so that the hot water mat 1 is prevented from being lifted and firmly fixed. .

  The method of forming the groove on the upper surface of the hot water mat may be formed by integral molding, by cutting the valley portion, or by stacking the mountain portions.

  By utilizing the hot water mat 1a according to claim 1 of the present invention, a hot water type floor heating system in which a single continuous and flexible hot water pipe 3 is laid in the pipe groove 2 on the upper surface of the hot water mat. In the system, even when four or more hot water pipes 3 are arranged in parallel in the straight part, the laying interval of the hot water pipes 3 in the straight part that is the same as or larger than the minimum rotation diameter specified by the manufacturer of the hot water pipe, On average, it can be reduced to half the minimum rotation diameter of the hot water pipe 3, the laying density of the hot water pipe 3 is doubled, the heat generation density per area is improved, and the heat generation amount of the hot water pipe of the same thickness is also Increase.

  With the pipe groove shape according to claim 2 of the present invention, the hot water mat 1a in the curved portion is cut, divided, and combined, so that the hot water pipe 3 is turned 180 degrees after the hot water pipe 3 is turned at the turning point from the forward path to the return path. Can be folded back at half the minimum rotation diameter.

  The adhesive that has adhered and hardened to the floor base inside the opening 4 of the hot water mat 1 becomes like a wedge, and acts to suppress the floating of the hot water mat 1 in addition to the surface adhesive force between the floor and the hot water mat 1.

  The raising of the bathroom floor can be realized simultaneously with the floor heating, and the raising height can be changed by sandwiching a foamed resin material or mortar as a raising material between the floor and the hot water mat 1.

  Hereinafter, an embodiment of a bathroom floor heating system embodying the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 6, in the dimensions of the hot water mat 1a and the hot water mat 1b, the thickness is 30 mm in common, and the curved hot water mat 1a having a planar dimension of 75 mm × 200 mm and a planar dimension of 350 mm × 200 mm are used. The hot water mat 1b of the straight line section is composed of two types, and these are cut, divided, and combined. The actual hot water mat 1a and the hot water mat 1b have dimensions such as the minimum rotating diameter of the hot water pipe to be used and the outer diameter of the hot water pipe. And it is not specified because it is determined by the number of pipe grooves. In FIGS. 1 and 6, since the minimum rotating diameter of the hot water pipe 3 is set to 100 mm, the laying interval of the hot water pipe 3 at the straight portion 1b of the hot water mat is 50 mm, and the shape of the hot water mat 1a at the curved portion is accordingly adjusted. Since the semicircular arc having a diameter of 100 mm is formed in a groove shape that overlaps at intervals of 50 mm, the horizontal width of the hot water mat 1a and the hot water mat 1b is 25 mm + 50 mm + 50 mm + 50 mm + 25 mm, which is 200 mm. The vertical dimensions of the hot water mat 1a and the hot water mat 1b are optional. The thickness dimension of the hot water mat 1 was set to 10 mm because the outer diameter of the hot water pipe 3 was 10 mm, and the thickness of the hot water mat 1 was also set to 10 mm × 2 pieces + 30 mm in consideration of the heat insulating effect from the bathroom floor.

  As shown in FIG. 7, two types of hot water mats 1 of a curved hot water mat 1a and a straight hot water mat 2a are cut and divided in accordance with the location where the floor heating of the bathroom washroom is desired to be laid out. Temporarily place in position.

  In particular, the warm water mat 1a at the curved portion can be cut, divided, and combined, so that the hot water pipe 3 can be rotated 90 degrees or 180 degrees, thereby laying the hot water pipe 3 while avoiding traps and gratings in the washing area. Can do.

  The hot water mat 1 temporarily placed on the floor is adhered to the bathroom floor with an adhesive, and the adhesive is filled into the openings 4 of the hot water mat 1a and the hot water mat 1b according to claim 3 and cured.

  After the adhesive is cured, a hot water pipe 3 is laid in the pipe groove 2 on the upper surface of the hot water mat 1 as shown in FIG. By using the hot water mat 1a of claim 1 and claim 2 of the present invention, even at the folded portion of the forward hot water pipe and the return hot water pipe, it is half of the minimum rotation diameter after turning 180 degrees by cutting, dividing and combining. The hot water pipe 3 can also be connected to the pipe groove 2 of the hot water mat 1b in the straight line portion having a distance of Further, the hot water pipe 3b on the return path is connected to the pipe groove 2 of the straight line portion having a half interval of the minimum rotation diameter while overlapping and intersecting with the hot water pipe 3a of the forward path laid at the intersection of the curved portion of the hot water mat. Can be laid.

  As a finish, in order to diffuse the heat radiation from the hot water pipe 3 to the surface finishing material from the top, the hot water pipe 3 laid in the pipe groove 2 on the upper surface of the hot water mat 1 is fixed to the hot water mat 1 with a metal tape. A metal plate such as aluminum or stainless steel is attached to the surface of the hot water mat 1, and finally a ceramic tile, which is a surface finish, is bonded to the metal plate with an epoxy adhesive, and caulked on the joints and surroundings of the ceramic tile.
