Description

[Technical field]

[0001] The present invention relates to a panel for constituting a temperature control mat for floor heating. More specifically, the present invention relates to a panel for a temperature control mat having a groove for mounting a hot water pipe on the upper surface. The present invention also relates to a method for installing the panel for a temperature control mat. [Background technology]

[0002] A panel for a temperature control mat for underfloor heating has a groove on the upper surface for arranging a hot water pipe, and a heat transfer member with an inverted Ω-shaped cross section is attached to the groove (Patent Document 1).

[0003] In Patent Document 1, a heat transfer sheet is attached so as to cover the groove and the heat transfer member. The heat transfer sheet is provided with perforations along the center portion in the width direction of the groove.

[0004] After placing this temperature control mat panel on the building's floor structure, a hot water pipe is placed along the upper side of the groove, and the hot water pipe is pushed into the groove while breaking the heat transfer sheet along the perforation. A floor finishing material is then provided to cover this mat with the hot water pipe.

[0005] When hot water is passed through the hot water pipe, heat is transferred from the hot water pipe to the heat transfer sheet via the heat transfer member, thereby providing floor heating. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2009-52778 A Summary of the Invention [Problem to be solved by the invention]

[0007] In Patent Document 1, the heat transfer member extends continuously from one end to the other end in the longitudinal direction of the groove. Therefore, when the panel is cut in a direction perpendicular to the groove direction to fit the on-site dimensions, the heat transfer member is also cut. This heat transfer member is made of thick aluminum with a thickness of about 0.8 mm (Patent Document 1, paragraph 0036), and burrs are generated when it is cut. Therefore, when a hot water pipe is attached to the groove of the cut panel, the hot water pipe may be damaged by the burrs.

[0008] To provide a panel for a temperature control mat that does not produce burrs on a heat transfer member even when the panel is cut in a direction crossing a groove to adjust the panel dimensions, and a method for installing the panel. [Means for solving the problem]

[0009] The present invention relates to the following.

[0010] [1] A panel for a temperature-controlled mat having a plate-shaped substrate having a groove on its upper surface for arranging a hot water pipe, and a heat transfer member attached to the groove, wherein a plurality of heat transfer members are installed at intervals in the longitudinal direction of the groove, and a cut line or slit is provided on the underside of the substrate extending in a direction perpendicular to the groove, and the cut line or slit is located on the underside of the substrate in a portion where the heat transfer member is not present.

[0011] [2] A panel for a temperature control mat according to [1], characterized in that the groove extends in a straight line from one end edge to the other end edge of the base material, the length of the base material in the groove extension direction is an integer multiple of 303 mm, and the cut lines or slits are provided at a pitch of 303 mm.

[0012] [3] The panel for a temperature control mat according to [2], wherein the length of the heat transfer members is 151.5 to 300 mm, and the distance between the heat transfer members is 10 to 100 mm.

[0013] [4] A panel for a temperature control mat according to [2] or [3], characterized in that the slit is a main slit whose depth is 10 to 30% of the base material, and a shallow slit having a depth smaller than the main slit is provided along and parallel to the main slit on the underside of the base material, and the shallow slit is located on the underside of the base material in a portion where the heat transfer member is not present.

[0014] [5] The panel for a temperature control mat according to [4], wherein the shallow slits are provided on both sides of the main slit.

[0015] [6] The panel for a temperature control mat according to [4] or [5], characterized in that the distance between the shallow slit and the main slit is 20 to 50 mm.

[0016] [7] A panel for a temperature control mat according to any one of [2] to [6], characterized in that an end of the heat transfer member is spaced a predetermined distance from the side of the base material, and a shallow slit is provided on the underside of the base material, passing between the end of the heat transfer member and the side of the base material, in a direction perpendicular to the groove.

[0017] [8] A method for installing a panel for a temperature control mat, comprising laying a panel for a temperature control mat according to any one of [1] to [7] on a floor surface of a structural body, the method comprising a step of cutting the panel for a temperature control mat along the slits to adjust the dimensions of the panel for a temperature control mat.

[0018] [9] A method for installing a panel for a temperature control mat, which comprises laying a panel for a temperature control mat according to any one of [2] to [7] on a floor surface of a structural body, the method comprising a step of cutting the panel for a temperature control mat along the slits or shallow slits to adjust the dimensions of the panel for a temperature control mat.

[0019]

[10] A method for installing a panel for a temperature control mat according to [8] or [9], characterized in that after the panel for the temperature control mat is laid, a hot water pipe is placed in the groove, and then a heat-equalizing sheet is placed on the upper surface. Effect of the Invention

[0020] Since the room dimensions of Japanese homes are measured in shaku (303 mm), the length and width of commercially available panels for temperature control mats are also integer multiples of 303 mm. Therefore, when adjusting the dimensions of a panel for a temperature control mat to fit the room dimensions, the panel is cut in 303 mm increments.

[0021] The panel for a temperature-control mat of the present invention has areas without heat transfer members at a predetermined interval (preferably 303 mm) in the groove extension direction, and cut lines or slits are provided in the panel for a temperature-control mat so as to cross these areas without heat transfer members. Therefore, when adjusting the dimensions of the panel for a temperature-control mat, the panel for a temperature-control mat can be cut along these cut lines or slits to obtain a panel for a temperature-control mat with the desired dimensions (length in the groove extension direction). Furthermore, since the heat transfer member is not cut during this cutting, no burrs are formed on the heat transfer member, and the hot water pipe is not damaged even when it is installed in the groove.

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0024] 1 to 5, this temperature control mat panel 1 includes a board-shaped base material 2 made of foamed synthetic resin, a small joist 3 made of plywood, and a heat transfer member 5 attached to a groove 4. In this embodiment, expanded polystyrene (EPS) is used as the foamed synthetic resin, and therefore, hereinafter, the foamed synthetic resin board-shaped base material 2 will be referred to as the EPS base material 2. In this embodiment, the heat transfer member 5 is an aluminum member having a substantially U-shaped cross section, and therefore, hereinafter, this heat transfer member 5 will be referred to as the U-shaped aluminum 3. However, the materials of the base material 2 and the heat transfer member 5 are not limited to these.

[0025] The temperature control mat panel 1 has a length L and a width W of 909 mm (3 shaku). Each EPS base material 2 is 909 mm long and 258 mm wide, and three sheets are used. Each small joist 3 is 909 mm long and 45 mm wide, and three pieces are used.

[0026] A small joist 3 is disposed between the long sides of each EPS base material 2. In addition, a small joist 3 is disposed along one side of the temperature control mat panel 1, and this small joist 3 is parallel to the other two small joists 3.

[0027] The thickness of each EPS substrate 2 and small floor joist 3 is preferably 1 to 5 mm, particularly 2 to 3 mm, larger than the diameter of the hot water pipe 10 (FIG. 10). The diameter of the hot water pipe 10 is usually 10 to 13 mm.

[0028] On the upper surface of each EPS base material 2, two grooves 4 for attaching hot water pipes are provided, each extending from one end to the other in the longitudinal direction.

[0029] A U-shaped aluminum piece 5 is attached to each groove 4. As shown in Fig. 4, the U-shaped aluminum piece 5 has a U-shaped portion 5a and a pair of flange portions 5b, 5b extending in directions away from each other from the upper end of the U-shaped portion 5a. The U-shaped portion 5a is fitted into the groove 4, and the U-shaped aluminum piece 5 is attached to the EPS substrate 2 so that the flange portions 5b overlap the upper surface of the EPS substrate 2 along both edges of the groove 4.

[0030] In this embodiment, the length of the U-shaped aluminum piece 5 is 243 mm, but may be 151.5 to 300 mm. Three U-shaped aluminum pieces 5 are attached to one groove 4 with a gap between them. The gap between the U-shaped aluminum pieces 5 is 60 mm, but may be 10 to 100 mm. The distance between the ends of the U-shaped aluminum pieces 5 arranged on both ends of the groove 4 in the longitudinal direction and the edge of the EPS substrate 2 is 30 mm, but may be 1 to 75 mm.

[0031] Two slits (main slits) 6 are provided on the back surface of each EPS substrate 2 in the width direction, i.e., in the direction perpendicular to the grooves 4. The slits 6 extend from one long side of the EPS substrate to the other long side. The distance between the slits 6 is 303 mm. The distance between the short side of the EPS substrate 2 and the slit 6 closest to the short side is also 303 mm. Each slit 6 extends between two U-shaped aluminum pieces 5.

[0032] The depth of the slit 6 is preferably 10 to 30%, particularly 15 to 25%, of the thickness of the EPS substrate 2. The slit 6 and shallow slit 7 described below can be formed using a cutter or the like, but the method of formation is not limited to this.

[0033] In this embodiment, shallow slits (hereinafter referred to as shallow slits) 7 are provided parallel to the slits 6 as shown in Figures 2 and 3. Shallow slits 7 are provided on both sides of each slit 6. The distance between the shallow slits 7 and the slits 6 is preferably 303 / 24 = about 13 mm to 303 / 6 = about 50 mm, particularly preferably 303 / 12 = about 25 mm to 303 / 8 = about 38 mm, and is set to 25.25 mm in this embodiment.

[0034] Shallow slits 7 are also provided along each short side of the EPS substrate 2, between the short side and the U-shaped aluminum 5. The distance between the shallow slits 7 and the EPS substrate and the short side is preferably 303 / 24 = about 13 mm to 303 / 6 = about 50 mm, particularly preferably 303 / 12 = 25 to 303 / 8 = about 38 mm, and is set to 25.25 mm in this embodiment.

[0035] As shown in Fig. 5, the EPS base material 2 and the small joist 3 are connected with an aluminum tape 8. The aluminum tape 8 is attached across the upper surface of the longitudinal edge of the small joist 3 and the upper surface of the edge of the EPS base material 2 that runs along the small joist 3.

[0036] When laying and constructing this temperature control mat panel 1, the end panels 11 are arranged along the sides in the width W direction of the temperature control mat panel 1, as shown in FIG.

[0037] 6 and 7(a), this end panel 11 is composed of three EPS substrates 12 and three small joists 13. The width of this end panel 11 is 909 mm, and the length is 151.5 mm (half a foot).

[0038] Small joists 13 are disposed between the EPS base materials 12. In addition, a small joist (small small joist) 13 is disposed along one side of the end panel 11, and this small joist 13 is parallel to the other two small joists 13.

[0039] The thickness of the end panel 11 is the same as the thickness of the panel 1 for the temperature control mat.

[0040] The upper surface of each EPS substrate 12 is provided with vertical grooves 14a and 14b, a horizontal groove 14e, a semicircular groove 14c, and a quadrantal groove 14d.

[0041] The vertical grooves 14a, 14b are provided in a positional relationship such that they are aligned in a straight line with the two grooves 4, 4 of the EPS substrate 2. The horizontal groove 14e extends from one side of the EPS substrate 12 to the other side. The semicircular groove 14c is provided so as to reach the vertical groove 14a to the vertical groove 14b. The midpoint of the semicircular groove 14c intersects with the horizontal groove 14e. The quadrant groove 14d is provided so as to reach each side of the EPS substrate 12 from the vertical grooves 14a, 14b. The depth of each of the grooves 14a to 14e is the same as that of the groove 4.

[0042] A recess 13a is provided on the top surface of the small common joist 13. The depth of this recess 13a is the same as that of the grooves 14a to 14e. The recess 13a is provided so as to traverse the small common joist 13 in the width direction.

[0043] The lateral groove 14e and the quadrant arc groove 14d are provided on the side edge of the EPS substrate 12 so as to face the recess 13a.

[0044] Although not shown in the figures, aluminum tape is attached so as to straddle the upper surfaces of the edges of the EPS substrate 12 and the small common joist 13 (excluding the recesses 13a). In addition, aluminum tape is attached so as to straddle the lower surfaces of the edges of the EPS substrate 12 and the small common joist 13. This connects the EPS substrate 12 and the small common joist 13.

[0045] When constructing a heated floor using this temperature control mat panel 1, the temperature control mat panel 1 is placed on the floor surface of the building frame, and an end panel 11 is further placed.

[0046] A plurality of temperature control mat panels 1 are arranged in the L direction in Fig. 1, and a plurality of temperature control mat panels 1 are also arranged in the W direction. If the on-site dimensions (the dimensions of the floor surface to be constructed) are not an integral multiple of 909 mm in the W direction, a temperature control mat panel 1 with a width of 303 mm or 606 mm is required. In this case, as shown in Figs. 8(a) and (b), by cutting the temperature control mat panel 1 along the small joists 3, a temperature control mat panel 1A with a width of 303 mm and a temperature control mat panel 1B with a width of 606 mm can be obtained.

[0047] Also, due to on-site dimensions, a temperature control mat panel 1 with a length of 303 mm or 606 mm may be required. In this case, as shown in Figures 9(a) and (b), by cutting the temperature control mat panel 1 along the slits 6, it is possible to obtain temperature control mat panels 1C and 1D with a length of 303 mm or 606 mm.

[0048] Although not shown in the figure, by cutting the temperature control mat panel 1 along the small joists 2 and also along the slits 6, a temperature control mat with a length of 303 mm or 606 mm and a width of 303 mm or 606 mm can be obtained.

[0049] In addition, if the on-site dimensions in the L direction are slightly shorter or longer than an integer multiple of 303 mm, a temperature control mat with dimensions slightly shorter or longer than an integer multiple of 303 mm can be obtained by cutting the temperature control mat panel 1 along the shallow slits 7.

[0050] Since the slits 6, 7 do not intersect with the U-shaped aluminum 5, even if the temperature control mat panel 1 is cut along the slits 6, 7, no burrs are generated in the U-shaped aluminum 5.

[0051] If necessary, not only the temperature control mat panel 1 but also the end panel 11 is cut along the small joist 13 to fit the on-site dimensions, and the width dimensions are adjusted.

[0052] After laying the temperature control mat panel 1 and the end panel 11 and fixing the panels 1, 11 to the structural floor by nailing them to the small joists 3, 13, the hot water pipe 10 is fitted into the groove 4 of the temperature control mat panel 1 and the grooves 14a, 14b of the end panel 11 as shown in Figure 10.

[0053] The hot water pipe 10, which has been drawn from the groove 4 into the vertical groove 14a, is drawn through the semicircular groove 14c into the adjacent vertical groove 14b, or through the quadrant groove 14d and the recess 13a. The hot water pipe 10 which has passed through the recess 13a is then drawn from the quadrant groove 14d of the adjacent EPS substrate 2 through the vertical groove 14b into the groove 4. The inflow and outflow ends of the hot water pipe are drawn out from the recess 13a, or the vertical groove 14a (or 14b), or the quadrant groove 14d located on the side of the arrangement of the temperature control mat panel 1 and the end panel 13 to the side of the arrangement, and connected to a hot water header (not shown).

[0054] After the hot water pipes 10 are installed, an aluminum sheet (heat equalizing sheet) with a thickness of approximately 30 μm to 100 μm is placed on the top surface to cover the temperature control mat panel 1 and the end panel 11, and a floor finishing material is then applied on top to form a heated floor.

[0055] It should be noted that a heat spreader sheet may be placed on the upper surface of the end panel 11 in advance. An example is shown in FIG. 7(b). The aluminum sheet 15 has the same dimensions as each EPS substrate 12. An adhesive is applied to the back surface of the aluminum sheet 15, and a release paper is attached to the aluminum sheet 15. The release paper is removed from an edge portion 15a along one side of the EPS substrate 12, and the edge portion 15a is attached to the EPS substrate 12.

[0056] As described above, the temperature control mat panel 1 of this embodiment has a portion without the U-shaped aluminum 5 in the extension direction of the groove 4, and the slit 6 and shallow slit 7 are provided so as to cross the portion without the U-shaped aluminum 5. Therefore, when adjusting the size of the temperature control mat panel 1, the temperature control mat panel 1 can be cut along the slit 6 or shallow slit 7 to obtain a temperature control mat panel of the target size (length in the groove extension direction). Furthermore, since the U-shaped aluminum 5 is not cut during this cutting, no burrs are formed on the U-shaped aluminum 5, and even if a hot water pipe is attached to the groove, the hot water pipe is not damaged. Furthermore, by providing the slit 6 or shallow slit 7, the temperature control mat panel 1 can be easily cut.

[0057] The above embodiment is an example of the present invention, and the present invention may be embodied in other forms. In the above embodiment, the dimensions of the temperature control mat panel are 909 x 909 mm, but they may be 909 x 1818 mm, 606 x 2424 mm, etc. In the above embodiment, slits are provided, but cut lines may be provided using ink or various markers.
