  A floor heating panel as described above comprises a plurality of joist members on the base member. When such a joist member is provided, the performance of the floor heating panel can be improved by further improving the uniformity of the temperature depending on the position in the plane direction of the floor heating panel. Therefore, it has been required to further improve the temperature uniformity in the planar direction of such floor heating panels.

  An object of the present invention is to provide a floor heating panel capable of further improving temperature uniformity.

  A floor heating panel according to one aspect of the present invention is provided on a base member that spreads in a flat plate shape, and is provided on the base member, extends in a first direction, and is separated from each other in a second direction orthogonal to the first direction. A floor heating panel comprising a joist member arranged and a plurality of pipe members provided on the base member and circulating a heat medium, wherein the plurality of pipe members is provided on the base member between the pair of joist members. An array region extending in the first direction is formed, in which the plurality of tubular members are spaced apart from each other at a distance of at least three in the second direction. The dimension of the spacing at the end in the second direction is set smaller than the dimension of the spacing at the central position in the second direction in the arrangement region.

  In the floor heating panel, the base member is provided with an array region in which a plurality of pipe members extend in the first direction and are arranged between the pair of joist members. In this array region, the plurality of tubular members are spaced apart from one another forming at least three intervals in the second direction. Here, in the arrangement region, the temperature is less likely to rise in the portion closer to the joist member than the central position in the second direction. On the other hand, the dimension of the spacing at the end of the arrangement region in the second direction is set smaller than the dimension of the spacing at the center position of the second direction in the arrangement region. By adopting such a configuration, the pipe members can be densely provided at the portion where the temperature does not easily rise, and the temperature can be easily supplied. Thereby, the uniformity of temperature can be improved by the part near the joist member and the part by the side of the central position far from the joist member. By the above, the uniformity of the temperature of the floor heating panel can be further improved.

At the position corresponding to the gap in the first direction, the finishing member fixed to the surface of the floor heating panel can not be fixed by not providing the joist member, and the fixing strength of the finishing material is reduced. Therefore, a joss piece is provided at a position corresponding to the gap in the first direction. Thereby, the finishing material of the base member can be fixed by the joist piece. Therefore, the fixing strength of the finishing material can be improved.

  According to the present invention, it is possible to provide a floor heating panel capable of further improving temperature uniformity.

  The material and the like of the end pieces 4 are the same as those of the end members 3. The joist piece 4 is different in arrangement and size from the joist member 3. The details of the joist piece 4 will be described later.

  The pipe member 6 is a member that is provided on the base member 1 and distributes the heat medium. A plurality of pipe members 6 are provided in parallel with each other so as to be embedded in the base member 1. As shown in FIG. 3, the pipe member 6 is embedded in the base member 1 in a state of being in contact with the heat dissipation sheet 8 using the groove 1 e formed on the surface 1 f of the base member 1. As the pipe member 6, in addition to a cross-linked polyethylene pipe, a polybutene pipe, a polypropylene pipe, a polyethylene pipe, a copper pipe, a resin pipe in which a metal wire is embedded in the circumferential surface can be used. Hot water is employed as a heat medium flowing in the pipe member 6. The size of the tube member 6 may be, for example, an outer diameter of 5 to 20 mm and an inner diameter of 3 to 16 mm.

  The pipe member 6 is stretched over substantially the entire area of the base member 1. The pipe members 6 are linearly arranged in the floor heating panel 100 along the Y-axis direction. Moreover, the pipe member 6 is arrange | positioned so that it may return by the edge parts 1a and 1b of the both end side of the Y-axis direction. At this time, the pipe member 6 is folded back at the positions of the end portions 3Ba and 3Bb of the joist member 3B. Moreover, the pipe member 6 is arrange | positioned so that it may return at the center position in the Y-axis direction of the base member 1. As shown in FIG. At this time, the tubular member 6 is folded back between the end 3Ab of the joist 3A and the end 3Ca of the joist 3C. That is, the floor heating panel 100 has an arrangement pattern of the pipe members 6 in which a plurality of rows of the pipe members 6 linearly arranged are arranged in parallel. A more detailed positional relationship of the arrangement of the tube members 6 will be described later.

  The header 7 is connected to the pipe member 6 and is a device for supplying a heat medium to the pipe member 6. The header 7 is arranged in a cut formed in one edge 1 b of the floor heating panel 100. A plurality of pipe members 6 are connected to the header 7 to configure a hot water circulation path of a plurality of systems (a plurality of circuits). By forming a plurality of sets of circulation paths, it is possible to reduce the temperature decrease of the hot water in each system, to radiate heat uniformly over the entire panel and to enhance the output.

  The heat dissipation sheet 8 is a member for transferring the heat of the heat medium of the pipe member 6 to the floor covering side. The heat dissipation sheet 8 is a flexible film or sheet having a thickness of 30 to 150 μm and excellent thermal conductivity, such as aluminum foil, tin foil, copper foil, metal foil such as stainless steel foil, metal woven fabric It is comprised from a cloth, a nonwoven fabric, a resin film or a resin sheet, or a lamination sheet etc. which combined these.

The above-mentioned base member 1 and joist members 3 and 4 are integrated by the heat dissipation sheet 8 stuck on these surfaces. The adhesive is not particularly limited as long as it has sufficient strength to be integrated.

  Next, the arrangement of the tube member 6 will be described in more detail with reference to FIGS. 2 and 4. In addition, although arrangement | positioning of the pipe member 6 between the joist members 3A and 3B is shown in FIG. 2, since the relationship of the same meaning is materialized between joist members 3B and 3C, description is abbreviate | omitted.

  In the base member 1, an array region 10 is formed between the pair of joist members 3A and 3B in which a plurality of tube members 6 extend in the Y-axis direction and are arranged. The arrangement area 10 is an area where the joist 3A and joist 3B overlap in the Y-axis direction. In the array area 10, the plurality of tube members 6 are spaced apart from each other with at least three intervals in the X-axis direction. In the present embodiment, six tube members 6 are provided, and five intervals are formed. In the arrangement area 10, each tube member 6 linearly extends so as to be parallel to the Y-axis direction.

  In the vicinity of the end on the positive side in the Y-axis direction of the arrangement region 10, each tube member 6 is curved so as to go around the end 3Ba of the joist member 3B. Each tube member 6 passes through the gap 12 between the end 3Ba and the edge 1a in a state of extending in the X-axis direction. Also in the vicinity of the end on the negative side in the Y-axis direction of the arrangement region 10, each tube member 6 is curved in order to wrap around the end 3Ab of the joist member 3A. Each tube member 6 passes through the gap between the end 3Ab and the end 3Ca while extending in the X-axis direction (see FIG. 1). The tube member 6 may extend straight in the Y-axis direction over the entire region of the arrangement region 10 in the Y-axis direction, and the tube member 6 may be curved at the end of the arrangement region 10 in the Y-axis direction.

Note that, for the sake of explanation, the pipe members 6 ₁ , 6 ₂ , 6 ₃ , 6 ₄ , 6 ₅ , 6 ₆ , 6 ₇ are referred to in order from the one that is far from the joist member 3B. Interval 16 ₁ is formed between the joists member 3A and the tubular member _61. Between the pipe member ₆ 1 and _{6 2 2} spacing 16 is formed. Between the pipe member ₆ 2, _{6 3} spacing 16 ₃ is formed. Between the pipe member ₆ 3, _{6 4} spacing 16 ₄ are formed. Between the pipe member ₆ 4, _{6 5} interval 16 ₅ is formed. The pipe member ₆ 5, ₆ between ₆ spacing 16 ₆ is formed. Interval 16 ₇ are formed between the joists member 3B and the pipe member _{6 6.} Further, the dimensions in the X-axis direction of the intervals 16 ₁ , 16 ₂ , 16 ₃ , 16 ₄ , 16 ₅ , 16 ₆ and 16 ₇ are assumed to be dimensions L 1, L 2, L 3, L 4, L 4, L 5, L 6 and L 7, respectively. In addition, in FIG. 2, although the pipe member 6 is shown by one solid line, in order to make an understanding easy, in fact, as shown in FIG. 3, the pipe member 6 is a member which has a predetermined | prescribed outer diameter. Accordingly, the solid line shown in FIG. 2 indicates the center line of the pipe member 6. For example, the interval 16 _2, a gap formed between the center line of the pipe member 6 ₂ and the pipe member 6 ₃ centerline. The dimensions L2, the dimension between the center line of the pipe member 6 ₂ and the pipe member 6 ₃ centerline.

Interval ₁₆ 2 formed by a pair of tubular members _6, 16 _3, 16 _4, 16 5, 16 ₆ dimensional relationships will be described. As shown in FIG. 4, the dimension of the space 16 at the end in the X-axis direction of the array area 10 is set smaller than the size of the space 16 at the central position CL in the X-axis direction in the array area 10.

In this embodiment, the spacing 16 at the ends of the X-axis direction of the array region 10, the spacing 16 _second end portion of the negative side of the X-axis direction, spacing 16 ₆ of the end of the positive side of the X-axis direction Applicable The spacing 16 at the center position CL in the X-axis direction in the array region 10, the interval 16 ₄ the center position CL is belongs interval corresponds. Therefore, dimensions L2, L6 spacing ₁₆ 2, 16 ₆ in the end portion of the X-axis direction of the arrangement region 10 is smaller than the spacing 16 ₄ dimensions L4 in the X-axis direction center position CL in the arrangement region 10 It is set.

Here, in the comparison of the size of the dimension of the space | interval 16, the magnitude of the magnitude | size of the extent which arises by a manufacturing error shall be included. That is, when the dimensions L2 and L6 of the intervals 16 ₂ and 16 ₆ are smaller than the dimension L ₄ of the interval 164 by 2 mm or more, it can be said that the dimensions are small beyond the range of the manufacturing error. More preferably, the dimensions L2 and L6 of the intervals 16 ₂ and 16 ₆ are preferably 10 mm or more smaller, 15 mm or more smaller, and 20 mm or more smaller than the dimension L ₄ of the interval 164.

Further, the dimensions of the center interval ₁₆ arranged on the end side of the X-axis direction than the spacing 16 ₄ in CL 3, 16 ₅ L3, L5 also, spacing at the center position CL in the X-axis direction in the array region 10 16 than the ₄ dimensions L4 is set smaller. In the present embodiment, the dimensions L3 and L5 of the intervals 16 ₃ and 16 ₅ are set to the same size as the dimensions L 2 and L ₆ of the intervals 16 ₂ and 16 ₆ .

  In the range satisfying the above-mentioned relationship, for example, the dimensions L2, L3, L5, and L6 may be set to 30 to 50 mm, the dimension L4 may be set to 50 to 70 mm, and the dimensions L1 and L7 may be set to 10 to 25 mm. L4 is more preferably 56 mm or more, or 57 mm or more from the viewpoint of temperature uniformity.

  In the present embodiment, the pipe members 6 extend straight in the Y-axis direction over the entire region of the arrangement region 10. Therefore, the above-described dimensional relationship is made throughout the array area 10. However, as the dimensional relationship of the tube member 6 differs from that of the other portions in a part of the array region 10, there may be a portion where the above-mentioned dimensional relationship does not hold. Preferably, the above-mentioned dimensional relationship may be established in an area of 10% or more, preferably 50% or more of the arrangement area 10.

By adopting the dimensional relationship as described above, the dimension L4 of spacing 16 ₄ at the center position CL is set widely. As shown in FIG. 2, joists piece 4 is disposed at a position corresponding to the gap between the tube member 6 ₃ and the pipe member 6 ₄ widened. Further, the joist 4 is formed at a position corresponding to the gap 12 in the Y-axis direction. That is, the joss piece 4 may have a portion protruding outward from the end in the Y-axis direction from the arrangement region 10. With this configuration, between the pair of tubular members 6 _3, 6 ₄ forming the gap 16 ₄ at the center position CL, the position corresponding to the gap 12 in the Y-axis direction, joists piece 4 is provided.

  In the present embodiment, the end 4 a on the side of the array region 10 of the joist pieces 4 is disposed at substantially the same position as the end 3 Ba of the joist member 3. However, the end 4 a on the array region 10 side of the joist piece 4 may extend to the array region 10 side more than the end 3 Ba of the joist member 3. The arrangement area 10 of the joist pieces 4 and the opposite side 4 b are provided so as not to interfere with the pipe member 6 and are separated from the edge 1 a.

  The dimension of the joist 4 in the Y-axis direction is smaller than at least joists 3A and 3C. Unlike the joist member 3, it is preferable that the joist piece 4 has a small influence on the uniformity of the temperature with respect to the floor heating panel 100. More specifically, the joist member 3 is a member that occupies 70% or more of the area of the edge 1 a and the edge 1 b of the base member 1 at a predetermined position in the X-axis direction. The area occupied by the joist member 3 is calculated by the total length of the joist members 3A and 3C when it is divided like the joist members 3A and 3C. On the other hand, the joist piece 4 occupies only a small area in the area between the edge portion 1a and the edge portion 1b of the base member 1 at a predetermined position in the X-axis direction, which almost affects the temperature uniformity. Do not give For example, as shown in FIG. 1, although four joist pieces 4 are provided at predetermined positions in the X axis direction in the base member 1, the length of the four joist pieces 4 in the Y axis direction is In total, the dimensions are extremely small compared to the overall dimensions between the edges 1a, 1b. Although a short joist member 3D is provided next to the header 7, the joist member 3D itself has a short length, but if combined with the joist member 3B provided at the same position in the X-axis direction, It has a sufficiently long dimension. Therefore, such a joist member 3D does not correspond to a joist piece, but corresponds to a joist member. That is, at the position where joist member 3D is arranged in the X-axis direction, the ratio occupied by joist member 3 in the area between edge portion 1a and edge portion 1b of base member 1 is the ratio between edge portion 1a and edge portion 1b It is calculated by the ratio of the dimension which added the length of the joist member 3B and joist member 3D with respect to the dimension between.

  More specifically, the length in the Y-axis direction of the joist piece 4 per one may be set to, for example, 30 to 150 mm. Further, the jolt piece 4 may be provided only at the position corresponding to the gap 12 in the Y-axis direction. Alternatively, even if a part of the joist 4 is provided so as to overlap the array region 10 in the Y-axis direction, the dimension of the overlapping portion in the Y-axis direction is the Y-axis direction of the array region 10 It is preferable that it is 20% or less of the dimension of, and it is preferable to set it as 6% or less.

  Note that the joist pieces 4 are also formed at positions corresponding to the gaps 13 between the end 3Ab of the joist member 3A and the end 3Ca of the joist member 3C in the Y-axis direction. The joist piece 4 has the same structure as the jotter piece 4 corresponding to the gap 12.

  Next, the operation and effects of the floor heating panel 100 according to the present embodiment will be described.

In the floor heating panel 100, an array region 10 is formed in the base member 1 between the pair of joist members 3 in which a plurality of pipe members 6 extend in the Y-axis direction (first direction) and are arranged. . In the arrangement region 10, the plurality of tube members 6 are arranged to be separated from each other by forming at least three intervals 16 (five intervals in the present embodiment) in the X-axis direction (second direction). Here, in the arrangement region 10, the temperature is less likely to rise in the portion closer to the joist member 3 than the central position CL in the X-axis direction. On the other hand, the dimensions L2 and L6 of the gaps 16 ₂ and 16 ₆ at the end of the array region 10 in the X-axis direction are compared to the dimensions of the gap 16 ₄ at the central position CL in the X-axis direction in the array region 10 Is set small. By adopting such a configuration, the pipe member 6 can be closely provided at a portion where the temperature does not easily rise, and the temperature can be easily supplied. Thereby, the uniformity of temperature can be improved by the part near the joist member 3 and the part by the side of the central position CL far from the joist member 3. By the above, the uniformity of the temperature of the floor heating panel 100 can be further improved.

The base member 1 has a pair of edge portions 1a and 1b opposed in the Y-axis direction, and in the position where the joist member 3 is provided in the X-axis direction in the base member 1, the space between the pair of edge portions 1a and 1b , is formed a gap 12, 13 joists member 3 is not provided, between the pair of tubular members ₆ 3, _{6 4} forming the gap 16 ₄ at the center position CL, a gap 12, 13 in the Y-axis direction At the corresponding position, a joist 4 may be provided. In the position corresponding to the gaps 12 and 13 in the Y-axis direction, since the joist member 3 is not provided, the finishing material fixed to the surface of the floor heating panel 100 can not be fixed, and the fixing strength of the finishing material Decreases. Accordingly, the joist piece 4 is provided at a position corresponding to the gaps 12 and 13 in the Y-axis direction. Thereby, the finishing material of the base member 1 can be fixed by the jot pieces 4. Therefore, the fixing strength of the finishing material can be improved.

  The present invention is not limited to the embodiments described above.

For example, in the above-mentioned embodiment, the interval formed with a pair of tube members was odd. Therefore, the "dimension of the spacing at the center position" was determined to be the dimension of one spacing at the center. Instead of this, as shown in FIG. 4B, the number of intervals may be even. In this case, the dimension of the two intervals on the center side corresponds to the "dimension of the interval at the center position". In the example of FIG. 4 (b), 7 pieces of pipe member ₆₁ through ₇ are provided. In this case, the size of the interval corresponding to the center position CL, the pipe member ₆ 3, and _{6 4} between spacing dimension L14 of the tube member ₆ 4, dimension L15 spacing between _{6 5} corresponds. Therefore, the dimension L17 between dimensions L12 and tube member ₆ 6 _{6 7} tubular member ₆₁ of the end portion, between _{6 2} intervals, the pipe member ₆ 3, spacing dimensions L14 between _{6 4,} and the pipe member 6 _{4, 6} is smaller than the spacing dimension L15 between _5. In the center position CL, the center line of the pipe member 6 ₄ is arranged. The dimensional range of the dimension L4 may be applied to the dimensions L14 and L15. The dimensional ranges of the dimensions L2, L3, L5, and L6 may be applied to the dimensions L12, L13, L16, and L17. The dimensional ranges of the dimensions L1 and L7 may be applied to the dimensions L11 and L18.

  Moreover, in the above-mentioned embodiment, dimensions L2, L3, L5, L6 other than the dimension L4 of the space | interval of a center position were set to the same dimension. Instead of this, as shown in FIG. 5A, the dimensions L3 and L5 may be smaller than the dimension L4 and larger than the dimensions L2 and L6. That is, from the dimension at the center position, a configuration may be adopted in which the dimension gradually decreases as the joist member 3 is approached. The dimensions L3 and L5 may be the same as the dimension L4.

Moreover, the number of tube members is not particularly limited as long as three or more intervals can be formed. For example, as shown in FIG. 5 (b), so as to form three intervals, the pipe member _{6 and} 62, _{6 3} may be provided. In this case, the dimension L23 of the central gap is set larger than the other dimensions L22 and L24. In this case, the dimension L23 may be set to 75 to 101 mm. The dimensions L22 and L24 may be set to 60 to 75 mm. The dimensions L21 and L25 may be set to 10 to 20 mm.

  Moreover, the joist piece 4 may be provided only in a part of the floor heating panel 100, or all may be omitted.

  Further, the size and the shape of the floor heating panel 100 are not particularly limited. For example, the upper half or the lower half in the Y-axis direction may be omitted.
