Description

  The present invention relates to a hot water mat for floor heating.

  Conventionally, a floor heating apparatus for heating a house from the floor surface has been proposed as one of the heating appliances. The floor heating apparatus includes a hot water mat for floor heating, and the hot water mat for floor heating is disposed on the floor surface side of the building to heat the floor surface. Specifically, the hot water mat for floor heating has a heat radiating pipe that circulates hot water, and the hot water mat for floor heating is disposed between a floor finishing material such as flooring and a floor base material. The house is heated from the floor by circulating hot water heated in the radiant pipe.

  By the way, the houses constructed in recent years have different shapes and sizes of floors depending on uses such as living rooms and bedrooms or types of buildings such as detached houses and apartments. In other words, the floor heating device needs to adapt the size and shape of the hot water mat for floor heating in accordance with the floor surface of the house. Generally, when the size of the hot water mat for floor heating is designed to occupy an area of 60% or more, preferably 70% or more of the floor surface to be laid, heating efficiency is said to be good.

  Here, the warm water mat for floor heating includes a plate-like main body that can hold the heat radiating pipe, and the main body is formed by combining a plurality of base material pieces. Each base material piece is generally made of foamed polyethylene, foamed polystyrene, or the like that can be expected to have a high heat insulating effect and that can be easily molded. And the warm water mat for floor heating which can adapt to the floor surface of every house is manufactured by manufacturing the base material piece which has several kinds of magnitude | sizes and shapes, and combining those base material pieces. In general, a warm water mat for floor heating is carried into a construction site in advance by combining base material pieces in a factory or the like.

In the hot water mat for floor heating disclosed in Patent Documents 1 and 2, all of the members corresponding to the base material pieces are rectangular.
Moreover, generally each base-material piece which comprises the warm water mat for floor heating is made without providing the reference | standard of a dimension. That is, the dimension of each part of the base material piece is not determined, and the hot water mat for floor heating is formed by combining a plurality of base material pieces with dimensions close to the floor surface of the construction site.

  Therefore, the hot water mat for floor heating described in Patent Literatures 1 and 2 sometimes causes a problem with some base material pieces until reaching the construction site or at the time of carrying in.

  More specifically, the hot water mat for floor heating includes a hot water header, and the hot water header is connected to an external heat source unit through a pipe, and thus is disposed on the peripheral end side of the hot water mat for floor heating. ing. And the substantially rectangular notch for arranging the warm water header which connects the outgoing side and the return side of a radiating pipe is provided in the base material piece which forms the warm water mat for floor heating, and it is easy to produce a crack near the notch It is a shape.

Here, in the hot water mats for floor heating disclosed in Patent Documents 1 and 2, the shape of the base material pieces 100 and 101 is rectangular as shown in FIGS. 9 and 10, and the long sides 102 and 103 of the rectangular shape are on the side. The notch 105,106 opened is provided and the attachment part of a warm water header is provided.
Therefore, in the hot water header portion, the notches 105 and 106 are provided, so that the effective width of Wa of the base material pieces 100 and 101 is narrow, and cracks are likely to occur.

  Thereby, the said base material piece may crack in the said site | part until it reaches a construction site or at the time of carrying in. Furthermore, when it was constructed in a state in which the base material piece was cracked, there was a concern that the flow of the heat radiating pipe disposed on the base material piece was shifted and the hot water did not flow smoothly.

In addition, as described above, the base material pieces constituting the warm water mat for floor heating are not made with reference to the dimensions, and the base material so that the size of the entire mat is close to the floor area of the construction site. It's just a combination of pieces. Therefore, the size of the base material piece is, for example, a base material piece having a size of 1.0 m in length and 0.561 m in width and a size of 0.5 m in length and 0.258 m in width.
On the other hand, the units of dimensions, scales, and the like are used as standard in houses, and the units are applied mutatis mutandis in building materials. For this reason, in the prior art, it is difficult to manufacture a hot water mat for floor heating having a shape that occupies a wide area of the floor surface of the room, and it is difficult to distribute hot water to the sides of the room.

That is, if it is a room of 6 tatami mats, it is the area between 2 vertical (12 scales) and 1.5 horizontal (9 scales). When converted to the metric system, it is 3.64m long and 2.73m wide. This is an odd dimension.
For example, when filling a room between 6 tatami mats with only a rectangular base material piece, if a base material piece that does not have a dimensional standard is used, the half-end size portion cannot be filled. That is, even when a warm water mat for floor heating is manufactured only with a rectangular base material piece having substantially the same shape and not having a reference dimension, and installed under the floor, it is 60% or more of the floor area of the room, preferably 70. % May not be filled.
For this reason, hot water cannot be distributed to the sides of the room, and the user feels uncomfortable when the user goes to the edge of the room because the floor is cold.

  In addition, in order to produce hot water mats for floor heating that completely fills the floor surface in order to distribute hot water to the sides of the room, small pieces are needed to fill the gaps, and the types of parts increase. , Component compatibility is reduced.

Further, the three J-shaped grooves 17 on the outer side surfaces j and k are divided into two by a large cutout portion 28.

  Here, when the large notch portion 28 and the small notch portion 20 are compared, the small notch portion 20 is fitted with the small joist-like short piece portion 6, so that cracks are formed from the small notch portion 20 as described above. It does not occur or break. On the other hand, the large notch portion 28 is merely provided with the hot water header 7 in the notch, and there is no member that fills the inside of the large notch portion 28 like the small radish-like short piece 6, so that it is cracked by an impact or the like. It is easy to break. However, as described above, in the prior art, each base piece is rectangular and designed with the Y-direction length fixed to one scale (303 mm). The length in the direction (153 to 203 mm) was shortened, which was a design constraint.

  Therefore, according to the present invention, the base piece 3 provided with the large cutout portion 28 is a basic shape base piece 11b, and the maximum length in the Y direction of the basic shape base piece 11b is within a certain range (353 to 400 mm). Design was possible. In this embodiment, as described above, the sum of the Y-direction length A of the outer surface j of the basic substrate piece 11b and the Y-direction length B of the end surface s should satisfy 606 mm. There is no need to match the length A and the length B in the Y direction of the end face s with the standard building dimensions (dimensions, scales, etc.). Thereby, in this invention, it becomes possible to ensure the length of the upper part of a Y direction from the large notch part 28 provided in the long piece part 14 of the basic | foundation type | mold base material piece 11b more than fixed (203-300 mm), and it breaks. The difficult base piece 3 can be provided. The Y-direction length A and the Y-direction length B employed in the basic substrate piece 11b need to be applied to the basic substrate piece 11a and the inverted substrate piece 12 described later.

  As shown in FIG. 4C, the inverted base material piece 12 has substantially the same configuration as the basic base material piece 11a described above, and only the positional relationship is different. That is, the basic substrate piece 11b has a configuration in which the basic substrate piece 11a is arranged in a mirror image with respect to the end surface r. In other words, the basic substrate piece 11 and the inverted substrate piece 12 have a different relationship.

The outer groove 10 and the inner groove 10 form an arc without penetrating the side surface of the material piece 29a. In addition, the space | interval of adjacent groove | channels 10 is distribute | arranged at equal intervals in the one edge part side of the Y direction of the edge part base material piece 29a. In other words, the U-shaped groove 31 of the end base piece 29a and the J-shaped groove 17 of the basic-type base piece 11 and the inverted base piece 12 can communicate with each other.

  The end base piece 29b is substantially the same as the above-described end base piece 29a, and the length of the end base piece 29b in the Y direction and the way of drawing the arc of the U-shaped groove 32 are different. Hereinafter, the description of the duplicated contents is omitted, and the same reference numerals are given to the same members as described above. That is, the length in the Y direction of the end base piece 29b is equal to the length A in the Y direction of the long piece 14 of the basic shape base piece 11 and the inverted base piece 12, and the Y direction of the end base piece 29a. Longer than length B. The U-shaped groove 32 forms an arc between the outer grooves 10 without penetrating the side surface of the end base piece 29b on the other Y direction end side of the end base piece 29b. The grooves 10 form an arc. The four grooves 10 are arranged at equal intervals on one end side in the Y direction of the end base piece 29b. That is, the U-shaped groove 32 of the end base piece 29b and the J-shaped grooves of the basic base piece 11 and the inverted base piece 12 can communicate with each other.

  The linear intermediate base material piece 30 has the same width (length in the X direction) as the end base material piece 29 and the Y direction length is an integral multiple of one scale (303 mm). Thereby, in this embodiment, even if it uses the intermediate base material piece 30 for heating area expansion, it is possible to extend the length in the Y direction without disturbing standard units (dimensions, scales, etc.) used for construction. it can. Further, as shown in FIG. 5C, four straight grooves (grooves 10) 33 penetrating in the Y direction are provided on the surface v of the intermediate base material piece 30. The linear grooves 33 are arranged at equal intervals between adjacent linear grooves 33. That is, the intermediate base material piece 30 can continue the groove 10 even when the basic base material piece 11, the inverted base material piece 12, or the end base material piece 4 is arranged vertically in the Y direction. . Therefore, the heat radiating tube 8 can be easily attached along the groove 10.
