Description

  The present invention relates to a hot water mat used for floor heating and a method of installing the same.

  As described in Patent Document 1, in the conventional floor heating, the flooring material 4 is disposed on the surface of the floor heating water mat 3 in which a heat radiating member such as a hot water pipe (built-in pipe) 2a is accommodated. A small joist 5 is disposed on the warm water mat 3, and a part where the warm water pipe 2a can cross is formed in the small jolt 5 (FIG. 5 of Patent Document 1). The flooring material 4 is disposed so that the longitudinal direction A is orthogonal to the small joists 5 and is nailed and fixed to the small joists 5 (FIG. 3 of Patent Document 1). Here, when the flooring material 4 is nailed and fixed, it is often the case that a nail is accidentally driven into the portion 2b of the hot water pipe 2a crossing the small joists 5. So, in patent document 1, the display seal 8 for nailing prevention is stuck on the site | part 5b of the small jot 5 which the warm water pipe 2a traverses. By confirming the seal 8, the construction worker is prevented from nailing the hot water pipe 2a instead of the small jot 5.

  By the way, a warm water mat of a type in which a header (connection fitting) is incorporated and an external pipe is connected to the header is widely adopted (see Patent Document 2). In such a type, although the external piping connected to the header is arranged under the floor, there is a possibility that the external piping under the floor may be nailed. Therefore, the construction worker worked with great care not to fall into such a situation, but it is desirable to take some measures.

  Recently, a warm water mat is widely used which is packaged in a folded state and carried in to a construction site as described in Patent Document 3.

  An aluminum foil is stuck on the surface of the warm water mat in order to improve heat transfer. In the case of such a structure, there is a possibility that the aluminum foil may be damaged if the folding method is incorrect at the time of packing. This will be described using the drawings.

  FIG. 14 is a view for explaining a normal folding method of the hot water mat.

  Usually, the packer folds as follows.

  First, as shown in FIG. 14A, the aluminum foil on the upper surface of the header 130 is turned up and folded so that the right side mat base 11R overlaps the central mat base 11C.

  By doing this, as shown in FIG. 14B, the aluminum foil stuck to the right side mat base 11R and the center mat base 11C is inside and not exposed, but it is stuck to the left side mat base 11L. Aluminum foil is exposed. Subsequently, the left side mat base 11L is folded so as to overlap the right side mat base 11R.

  In this case, as shown in FIG. 14C, the header 130 abuts on the back surface of the right side mat base 11R (the surface to which the aluminum foil is not attached), and the back surface of the header 130 is exposed. become. We pack this in cardboard etc. In this state, the header 130 does not abut the aluminum foil, so the header 130 does not damage the aluminum foil. The header 130 made of brass or the like abuts on the mat substrate, but since the mat substrate is formed of, for example, foamed polyethylene or polystyrene foam, it does not damage even if the header 130 abuts.

  FIG. 15 is a diagram for explaining how to fold the hot water mat incorrectly.

  However, the packing worker may accidentally fold as follows.

  First, as shown in FIG. 15A, the aluminum foil on the top surface of the header 130 is flipped over, and then the left side mat base 11L is folded so as to overlap the central mat base 11C. Subsequently, as shown in FIG. 15 (B), the right side mat base 11R is folded so as to overlap the left side mat base 11L.

  In this case, as shown in FIG. 15C, the header 130 is in contact with the aluminum foil affixed on one side to the central mat substrate 11C, and the back surface of the header 130 is affixed to the right side mat substrate 11R. It will be in contact with the aluminum foil. If packing in a cardboard or the like in such a state, the header 130 may move up and down due to vibration of a truck or the like while being transported to the construction site, and the aluminum foil may be damaged.

  Therefore, conventionally, the upper surface and the lower surface of the header 130 are covered with a tape so that the header 130 does not directly contact the aluminum foil.

  However, covering the upper surface and the lower surface of the header 130 with the tape in this manner is complicated.

  The present invention has been made focusing on such conventional problems. The object of the present invention is to prevent nailing of external piping disposed under the floor, and also that the header may damage the aluminum foil even if the packing operator makes a mistake at the time of packing. It is providing a hot-water mat for floor heating and its construction method.

  The present invention solves the above problems by the following solution means.

  Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

  FIG. 1 is a view for explaining the basic structure of floor heating.

  First, the basic structure of floor heating will be described to facilitate the understanding of the present invention. Since the floor heating hot water mat 10 is laid on the floor 20, the floor 20 will be described first.

  The floor 20 is, for example, a floor of a wooden building, and a plurality of joists 21 are arranged in parallel at regular intervals (usually 303 mm pitch). A heat insulating material 22 is disposed between the joists 21. The thickness of the heat insulating material 22 is usually substantially the same as the thickness of the joists 21. A step control panel 23 is laid on the joists 21 and the heat insulating material 22 so as to cover the whole. The stecon panel 23 is, for example, a plywood with a thickness of 12 mm. The control panel 23 is fixed to a joist 21.

  The warm water mat 10 is laid on the step control panel 23. The hot water mat 10 is usually laid to occupy 80% of the floor area of the room to be heated. A dummy control panel 24 is laid between the periphery of the warm water mat 10 and the wall of the room.

  Subsequently, the details of the warm water mat 10 will be described. The warm water mat 10 includes a mat base material 11 as a supporting base material, a small root 12, a hot water pipe (internal piping) 13, and an aluminum foil 14.

  The mat substrate 11 is a member having a thickness of about 12 mm and a substantially rectangular shape in a plan view. A buried groove 11 a having a shape corresponding to the cross-sectional shape of the hot water pipe 13 is formed in the mat substrate 11 (details will be described later), and the hot water pipe 13 is held in the buried groove 11 a. The mat substrate 11 is made of a heat insulating material so that the heat of the hot water pipe 13 is not dissipated downward. As a material of the mat | matte base material 11, the foaming polyethylene (for example, 20 times of foaming ratio) which has a heat insulation function, a polystyrene foam, etc. are suitable, for example. The mat substrate 11 is sufficient as long as the hot water pipe 13 can be held at a predetermined position, and a general-purpose heat insulation panel or a heat conduction member instead thereof may be used. In this case, it is necessary to put a heat insulating material under the heat conduction member.

  The small joists 12 are members to which a large number of strip-like flooring materials 30 are nailed and fixed as described later. The thickness of the small joists 12 is, for example, 12 mm identical to that of the mat substrate 11. The small joists 12 extend from the back edge of the mat substrate 11 to the front side or from the front edge to the back side. The small joists 12 extended from the back edge toward the front and the small jots 12 extended from the front edge toward the back are alternately arranged in parallel. One end 12 a of the small jot 12 does not reach the edge of the mat substrate 11. A gap from one end 12 a of the small joist 12 to the edge of the mat substrate 11 is set to be narrower than the width W (typically 303 mm) of the flooring material 30. In addition, the distance between adjacent small joists 12 and between the small jots 12 at both ends and the dummy control panel 24 is shorter (for example, 303 mm pitch) than the length of the flooring material 30 (typically, 1800 mm), It is set.

  The hot water pipe (internal pipe) 13 is held by the embedded groove 11 a of the mat substrate 11 and is incorporated in the mat substrate 11. The warm water pipe 13 is a heat transfer pipe through which warm water (water, a mixed solution of water and ethylene glycol, a mixed solution of water and propylene glycol, etc.) as a heat medium flows. The hot water pipe 13 is meandered and arranged along the installation path made between the small joists 12 and supported by the mat substrate 11. As the hot water pipe 13, for example, a cross-linked polyethylene pipe, a polypropylene pipe, a polybden pipe or a metal pipe can be used, but a cross-linked polyethylene pipe is particularly preferable. The hot water pipe 13 is substantially circular in cross section. When a cross-linked polyethylene tube is installed with a bend smaller than the specified minimum bending radius, the tube may be flattened to reduce the flow rate or a large stress may be left in the tube to reduce the life. It is constructed so that the minimum bending radius specified there can be secured. As described in the website of the Cross-linked Polyethylene Pipe Industry Association, if the pipe diameter (nominal diameter) is 13 mm or less, the minimum bending radius is set to 150 mm. If the pipe diameter (nominal diameter) is 16 mm, the minimum bending radius is set to 200 mm. If the pipe diameter (nominal diameter) is 20 mm, the minimum bending radius is set to 300 mm. In order to increase the contact area with the aluminum foil 14 to improve the heat transfer efficiency, the cross-sectional shape of the hot water pipe 13 may be an elliptical shape.

  The aluminum foil 14 is a covering material that covers the mat substrate 11, the small joists 12, and the hot water pipe 13, and has a role of transmitting the heat from the hot water pipe 13 or holding the heat.

  A paste is attached to the back surface of the aluminum foil 14 and integrated by covering the surface of the mat substrate 11, the small joists 12, and the hot water pipe 13. Although the surface of the header 130 is also covered with the aluminum foil 14, is it possible that the back surface of the aluminum foil 14 covering the header 130 is not scraped so that the operation of the external piping connection process described later can be smoothly performed; Alternatively, the aluminum foil 14 and the header 130 are not adhered by sandwiching a release paper or the like.

  FIG. 2 is a view showing an essential part of a first embodiment of a floor heating hot water mat according to the present invention. FIG. 2A is a plan view showing the floor-heating water mat before the aluminum foil 14 is attached. FIG. 2A-2 is a cross-sectional view of FIG. Drawing 2 (B) is a top view showing the important section of a 1st embodiment of the warm water mat for floor heating.

  Subsequently, the structure of the first embodiment will be described with reference to FIG.

  As shown in FIG. 2 (A), a part of the mat substrate 11 is cut out, and the header 130 is disposed in the cut portion. The thickness of the header 130 is, for example, 12 mm identical to that of the mat substrate 11. The hot water pipe 13 is connected to the header 130. The hot water of the heat source is supplied to the header 130 and flows from the header 130 to the hot water pipe 13. Also, the warm water that has warmed the floor flows back to the header 130 and then flows to the heat source. Hot water circulates through the hot water pipe 13 in this manner.

  As shown in FIG. 2 (A-2), a buried groove 11a having a shape corresponding to the cross-sectional shape of the hot water pipe 13 is formed in the mat substrate 11. The hot water pipe 13 is held by the embedded groove 11a.

  Then, as shown in FIG. 2B, the aluminum foil 14 is attached so as to cover the mat substrate 11, the small joists 12 and the hot water pipe 13, and the band sheet 100 is so covered as to hide the upper surface of the header 130. Is provided. As described later, the entire length of the band sheet 100 is a length such that the portion folded back when packing the hot water mat 10 can hide the back surface of the header 130. In the band sheet 100, the characters "prohibition of nailing" are displayed from the edge 11b of the mat substrate 11 to a predetermined length L, and the characters and "arrows of piping attention" are displayed below it. The predetermined length L will be described later. Here, in the aluminum foil 14, the area where the small jot 12 is present on the back is colored green so that the position of the small jot 12 can be known.

(Packing method of hot water mat)
FIG.3 and FIG.4 is a figure explaining the packing method of a warm water mat.

  First, the band sheet 100 is folded back to the back of the mat substrate 11 as shown by the arrow in FIG. As described above, since the band sheet 100 has a long overall length, the folded portion can hide the back surface of the header 130.

  Next, as shown by the arrow in FIG. 3B, the right side mat base 11R is folded so as to overlap the central mat base 11C.

  Subsequently, as shown by the arrow in FIG. 4A, the left side mat base 11L is folded so as to overlap the right side mat base 11R.

  In this case, as shown in FIG. 4B, the header 130 abuts on the right side mat substrate 11R via the band sheet 100, and the back surface is covered with the band sheet 100. The hot water mat 10 is packaged in such a state. In this state, the header 130 is not in contact with the aluminum foil, but is in contact with the aluminum foil via the band sheet 100. Therefore, the header 130 moves up and down due to the vibration of the truck or the like during conveyance to the construction site. Also, the header 130 does not damage the aluminum foil.

(Construction method of warm water mat)
5-10 is a figure explaining the construction method of a warm water mat. In FIGS. 5 to 9, FIG. (A) is a plan view, and FIG. (B) is a cross-sectional view taken along the line B-B in FIG. Further, in the figure (A), the band sheet 100 and the aluminum foil 14 on the top surface of the header 130 are omitted in order to facilitate understanding of the invention by avoiding complication of the figure. The aluminum foil 14 on the upper surface of the header 130 is omitted in FIG.

  After the hot water mat 10 is carried to the construction site, the packing is released in the reverse procedure of the above-described packing method. Further, the front end of the band sheet 100 is brought out from the back of the warm water mat 10 to the front. In such a state, the warm water mat 10 is spread on the stecon panel 23 (mat laying step). Since the band sheet 100 is folded back so as to conceal the back surface of the header 130 when the hot water mat 10 is packed, when the leading edge of the band sheet 100 is brought out of the back surface of the hot water mat 10, FIG. As shown in, there is a peculiarity to be convex (angular) upward.

  And if the laying position of warm water mat 10 is decided, as shown in Drawing 5 (A), penetration hole H to floor 20 (steech panel 23 and heat insulating material 22) of predetermined distance from edge 11b of mat substrate 11 Is opened (opening process). This distance is a distance which can extend under the floor from the through hole H while ensuring that the warm water pipe 13 connected to the header 130 is subjected to an excessive force, that is, a radius larger than the minimum bending radius. Typical numerical values are specified in the construction instruction diagram, but in one example, a through hole H with a diameter of 80 mm is formed at a position 50 mm from the edge 11 b of the mat substrate 11. However, when there is a joist 21 or a large pull under the floor, the through hole H can be opened at a position shifted as appropriate.

  Subsequently, as shown in FIG. 6A, the caps 131 at the inlet and outlet of the header 130 are removed, and the external piping 40 is connected (external piping connection step). In addition, although the band sheet 100 is folded back so that the back surface of the header 130 may be concealed at the time of packing of the warm water mat 10, a worker must bring the tip of this band sheet 100 out of the back of the warm water mat 10 to the front. Since the external pipe 40 can not be connected to the header 130, the band sheet 100 can not be forgotten.

  Next, as shown in FIG. 7A, a dummy control panel 24 is laid in accordance with the edge 11b of the mat base 11 (a dummy control panel laying step). Notches 24 a are formed in the dummy control panel 24 so as not to crush the external piping 40 while disturbing the path of the external piping 40.

  Subsequently, as shown in FIG. 8A, the flooring material 30 is sequentially disposed on the warm water mat 10 (Oita 12) and fixed to the Ojo 12 with a nail 50 (nailing process). The nail (also referred to as "floor nail" or "stapling") used here is often about 30 mm but may be about 50 mm.

  As shown in FIG. 10A, the nailing to the small joists 12 is performed by striking the nail 50 diagonally to the male sand 30a. Then, as shown in FIG. 10 (B), the female 30b of the flooring material 30 of the next row is inserted into the male 30a of the flooring material 30 nailed to the small jot 12 and is inserted into the male 30a of the flooring material 30. A nailing is done. Subsequently, the female 30b of the next row of the flooring material 30 is inserted into the male 30a of the flooring material 30, and the male 30a of the flooring material 30 is nailed. These tasks are repeated sequentially.

  Next to the placement of the flooring material 30 on the warm water mat 10 (small net 12), the flooring material 30 is also placed on the dummy control panel 24 as shown in FIG. It is fixed by the nail 50 (nailing process).

  Here, in order to facilitate understanding of the function and effect of the present invention, problems that may occur when the band sheet 100 is absent (ie, the present embodiment is not implemented) will be described with reference to FIG. In addition, although there is no band sheet 100, it has described by the broken line so that the position in this embodiment may be known.

  As described above, the nail 50 is often about 30 mm, but may be about 50 mm. In any case, when the band sheet 100 is not present (ie, the present embodiment is not performed), as shown in the C portion of FIG. The piping 40 may be damaged.

  On the other hand, in the present embodiment, when the through hole H is opened at the position defined in the construction instruction drawing and the external pipe 40 is passed, the nail penetrating the dummy control panel 24 may damage the external pipe 40 The words "No nailing" is displayed in a certain area.

  More specifically, FIG. 11 shows the case where the flooring material 30 is fixed on the stecon panel 23 in a situation where the notch 24a is hidden by the flooring material 30 when the band sheet 100 of the present embodiment is not present (this invention is not implemented). Indicate the situation you are doing. As shown in FIG. 11 (A), in this situation, since the warm water mat 10 and the notch 24a are not already visible from the eyes of the worker, nailing is performed at an arbitrary place. As a result, when there is the external piping 40 below the nailing point, the external piping 40 may be damaged or the bending radius smaller than the specified minimum bending radius when the external piping 40 is pushed by the nail. There is a risk of

  On the other hand, FIG. 12 shows the case where the present application is carried out and a nail is struck at the “prohibition of nailing” end. As shown in FIG. 12, the nail does not damage the external pipe 40.

  The above-mentioned predetermined length L is, in short, a length that defines such a range. Specifically, as described above, in this embodiment, the thickness of the heat insulating material 22, the stecon panel 23, and the dummy panel 24 is approximately 12 mm. That is, the total thickness of the heat insulating material 22, the step control panel 23, and the dummy control panel 24 is 36 mm. Since the flooring material 30 is disposed on this, and the nail 50 of 50 mm is struck at an angle of 45 degrees to the male sand 30a, the nail 50 does not penetrate as shown in FIG. 12 (B). There is no fear that the nail 50 may damage the external piping 40. That is, the predetermined length L is a length for setting a location where the nail 50 does not penetrate and be exposed even if a 50 mm nail 50 is struck at an angle of 45 degrees to the male sand 30a of the flooring material 30 . As described above, according to the present embodiment, since the characters “prohibition of nailing” are displayed on the band sheet 100 from the edge 11b of the mat substrate 11 to the predetermined length L, the nailing operator should not nail The range can be easily grasped, and it is possible to prevent the external piping 40 from being damaged by the nail by not nailing the area.

  In addition, on the band sheet 100, the words “Pipe Warning” and an arrow are displayed under “No nailing”. "Piping caution" indicates a portion where the external piping 40 may be damaged when the through hole H is opened to a position shifted from the position specified in the construction instruction diagram, and the through hole H is Even if it deviates from the position of the construction instruction diagram, attention can be drawn so as not to damage the external piping 40.

  As described above, according to the present embodiment, since the band sheet 100 is provided, the nailing operator can easily grasp the range in which the nailing should not be carried out. Damage to the external piping 40 can be avoided. In addition, “Pipe Caution” is displayed under “No nailing prohibited”, so the external pipe 40 can be opened even if the through hole H is opened at a position deviated from the position specified in the construction instruction diagram. It can call attention not to hurt.

  FIG. 13 is a diagram for explaining the further function and effect.

  The packing worker packs the hot water mat 10 in the order of FIG. 3 (A) → FIG. 3 (B) → FIG. 4 (A) → FIG. 4 (B) as described above. Thus, after the band sheet 100 is folded back to the back of the mat substrate 11, it may be accidentally folded as follows.

  That is, as shown in FIG. 13 (A), the left side mat base 11L is folded so as to overlap with the central mat base 11C, and then, as shown in FIG. 13 (B), the right side mat base 11R is on the left side. It is folded so as to overlap with the mat substrate 11L.

  Even if the sheet is accidentally folded in this manner, according to the present embodiment, the header 130 does not contact the center mat substrate 11C and the right mat substrate 11R directly, but does not contact the belt sheet 100. Since it contacts, even if the header 130 moves up and down by vibration of a truck etc. on the way to the construction site, the header 130 does not damage the aluminum foil.

  As described above, according to the present embodiment, since the band sheet 100 is provided, the nailing operator can easily grasp the range in which the nailing should not be performed, and by nailing there, It is possible to prevent the external piping 40 from being damaged by nails. In addition, “Pipe Caution” is displayed under “No nailing prohibited”, so the external pipe 40 can be opened even if the through hole H is opened at a position deviated from the position specified in the construction instruction diagram. You can call attention not to hurt.

  Moreover, when the warm water mat 10 is spread on the stecon panel 23, the band sheet 100 is convex (in the shape of a mountain) upwards (FIG. 5 (B)), but the flooring material 30 is disposed on the band sheet 100 Then, as shown in FIG. 8B, the band sheet 100 is curved. By curving the band sheet 100 in this manner, the installer is very easy to see the display of "prohibition of nailing" and "precaution of piping". This brings more attention.

  In addition, even if the packing operator makes a mistake at the time of packing, the aluminum foil 14 is not damaged by the header 130.

  As mentioned above, although the embodiment of the present invention was described, the above-mentioned embodiment showed only a part of application example of the present invention, and in the meaning of limiting the technical scope of the present invention to the concrete composition of the above-mentioned embodiment. Absent.

  For example, in the above description, the tri-fold type hot water mat is described as an example, but the invention can also be applied to a six-fold hot water mat in which a three-folded one is further folded in two.

  In the above description, the left mat substrate 11L is described with the header 130 attached thereto, but the header 130 may be attached to the right mat substrate 11R or the central mat substrate 11C. . When the header 130 is attached to the right side mat base material 11R, the left side mat base material 11L is first folded and stacked on the central mat base material 11C, and then the right side mat base material 11R is folded to form the header 130. Since there is no direct contact with the aluminum foil 14, the header 130 will not damage the aluminum foil 14. Further, even if the folding order is wrong, the aluminum foil 14 is not damaged because the band sheet 100 is present. Even when the header 130 is attached to the central mat substrate 11C, since the header 130 does not directly contact the aluminum foil 14 because the band sheet 100 is present, the aluminum foil 14 is not damaged.

  The presence or absence of the aluminum foil 14 on the upper surface of the header 130 does not matter. The band sheet 100 may be provided on the aluminum foil on the top surface of the header 130, or the band sheet 100 may be provided without the aluminum foil on the top surface of the header 130. Furthermore, the aluminum foil on the upper surface of the header 130 may be elongated to form the band sheet 100.
