Description

  The present invention relates to a floor heating hot water mat used for hot water floor heating laid in an apartment house, a detached house, and the like, and a winding method for packing this compactly.

  Conventionally, heat radiation pipes for residential floor heating hot water mats have been made by installing a heat radiation pipe made of heat-resistant resin on the base board of expanded polystyrene (foamed polystyrene polymer) with engraved piping path grooves, and a heat radiation sheet on the upper surface. There has been a construction method in which a hot water mat in which (aluminum sheet or the like) is stretched over the entire surface is laid in a target room, and floor finishing materials such as flooring are fixed over the entire surface of the room.

  The heat radiating pipe is sandwiched and fixed between the polystyrene foam and the heat radiating sheet, and hot water is passed through the heat radiating pipe during heating, but how to raise the temperature of the flooring surface and increase the thermal efficiency of the hot water as heating is examined. There is a problem, a surface plate for heat equalization is provided on the upper surface of the base board, a heat transfer promotion member is provided between the laying heat radiating pipe and the surface plate for heat equalization, and further, the laying heat radiating pipe and the laying groove It has been proposed to form an air space between them (Patent Document 1).

Moreover, since mats that have already been piped are laid in the target room, there is a problem that they are bulky and extremely difficult to handle during transportation and storage. Various proposals have been made in response to this problem. Recently, a method of winding a mat in a roll shape (Patent Documents 2 and 3) and a method of folding a mat (Patent Document 4) have been proposed.

  However, in the pattern of the heat radiating pipe laying path, when the base board constituting the mat is rolled or folded, it is not possible to avoid the intersection with the bent part of the roll or the bent part of the folding. Therefore, the heat-dissipating tube inserted in the portion intersecting with the fold when the mat is rolled or folded is forced to bend or refract.

  Forcibly bent or refracted heatsinks, even if you try to lay a heated or mated hot water mat in the target room and lay it in the target room, it will not be restored to its original shape immediately after buckling, which will hinder smooth laying work. Can lead to serious problems that may cause the part to deform or break.

  In addition, the split groove formed in the bent portion that winds or folds the hot water mat is formed so as to penetrate from end to end across the hot water mat, so when the hot water mat is spread and laid in the target room, The split groove that once expands and breaks during winding, etc., creates a gap in the radiating pipe laying groove at the intersection with the radiating pipe laying groove, and the air heated by heat dissipation during heating operation is released from this gap, and the thermal efficiency There is a problem that makes it worse.

  Furthermore, the pattern of the heat radiating pipe laying path is such that one heat radiating pipe laying groove is bent in a single stroke and both ends reach the heat source connection port, but it is drawn on a single base board constituting the mat. It is troublesome to engrave the radiating pipe laying groove by bending it into a shape, and since the area of the baseboard increases, it is reinforced by inserting small joists in the center part, and in the bending groove part above and below the laying groove There is a problem that it is necessary to insert and reinforce the small radish intermittently.

  In addition to making the base board complex, making the base board complex and difficult to machine, the on-site builder has a continuous line of small and thick roots. It is easy to misunderstand, and when nailing to the small joists and fixing the hot water mat, nailing is done at the intermittent parts of the small joists and small joists to cause damage to the base board or unstable fixing I came.

  The present invention is intended to address the above-described problems, and a heat dissipating pipe laying groove of a heat dissipating pipe that radiates and recirculates along the laying path is formed on the surface of the base board, and the back surface intersects with the heat dissipating pipe laying groove. A split groove is formed which is interrupted at the section and crosses and parallels the board along the radiating tube laying groove array, and a cutter is cut at the intermittent section of the split groove at the intersection.

  That is, when wrapping or folding the heat radiating pipe laying mat, the surface of the mat is inside, so the split groove formed on the back surface of the base board that crosses and parallels the board along the heat radiating pipe laying groove row Expands to the outer surface, the bottom of the split groove tears, and the flexible heat-dissipating sheet stretched on the surface of the base board maintains the integrity of the base board so that it can be bent.

  At this time, the split groove at the intersection with the laying heat radiating pipe is torn to form an irregular cracked cross section, but at the intersection with the radiating pipe laying groove, the cutter is cut away from the beginning. Even when the split groove expands to the outer surface and the bottom of the split groove is torn, the cut section slides along the flank of the radiating pipe so that it does not resist bending. To ease.

  Also, when the hot water mat is expanded and restored to its original shape and laid in the target room, the expanded split groove closes and contracts leaving the groove width, but the remaining groove width expands. In addition to maintaining the margin and flexibility, the cross section of the cutter cuts back to a close state, so that the laying shape of the radiator pipe is fixed in a stable manner, and at the same time, the shape of the entire hot water mat is stabilized. .

  In addition, when the hot water mat is expanded and restored to its original shape and laid in the target room, the smooth cross section due to the cutting of the cutter at the intersection will be restored to the close contact state. The gap of the radiating pipe laying groove formed at the intersection of the groove with the radiating pipe laying groove is also sealed, the release of air warmed by heat radiation is prevented, and it is stored in the laying radiating pipe and has the effect of increasing the thermal efficiency I was able to do it.

  Furthermore, the pattern of the heat radiating pipe laying path formed in a single stroke on the base board constituting the mat has a bent portion concentrated on the upper and lower ends of the board. Focusing on the simple shape of the parallel laying grooves, the base board is divided into three pieces, the upper and lower ends where the radiating pipe laying grooves bend and the central part where the laying grooves are linearly paralleled. The groove for laying the heat radiating pipe was cut.

  With this configuration, the vertical dimensions of the upper and lower ends of the baseboard are shortened, and the upper and lower ends that have become unstable in shape as an integrated object are separated from the laying groove straight portion in the center and stabilized. Since it is possible to omit the fitting of small radish that is easily misunderstood, the cost can be reduced by that amount, and erroneous nailing can be prevented.

Embodiments of the present invention will be described below with reference to the drawings.
Reference numeral 1 denotes a base board made of polystyrene foam, which is reinforced by fitting small joists 5 at predetermined intervals, and a heat radiating pipe laying groove 11 is engraved on the surface along a heat radiating pipe laying path for circulating heat. A heat radiating pipe 13 made of a heat-resistant resin is fitted into the groove 11 and the heat radiating sheet 3 is stretched over the entire surface of the pipe.

  As another embodiment, as shown in FIG. 6, the base board 1 is divided into an upper end piece 1a, a central straight line laying groove parallel piece 1b, and a lower end piece 1c. If the heat radiating tube is integrated by laying the pieces side by side and laying the heat radiating tube, the small radish can be omitted as described above, and erroneous nailing can be prevented. .

  The laying groove 11 is formed into an insertion clamping structure that clamps and fixes the maximum pipe diameter pipe abdominal surface portion of the laying pipe with a reverse taper structure from the opening 12 to a predetermined depth position by the width of the groove inner wall. Therefore, since the groove diameter above the depth position is narrower than the diameter of the heat radiating pipe 13, once the heat radiating pipe 13 is press-fitted, it does not come out of the laying groove 11 unless the lifting force from the lower part acts. .

  The laying path pattern of the heat radiating pipe 13 is set in such a form that the heat radiating pipe laid groove is radiated from the heat source connection port A to the surface of the base board 1 and circulates again to the heat source connection port A. 2 is set in a substantially parallel and parallel state, and on the back surface of the base board 1 corresponding thereto, the laying grooves 11 of the laying path pattern are arranged along the radiating tube laying groove row in which the laying grooves 11 are in a substantially parallel and parallel state. As shown in FIG. 2, a plurality of split grooves 2 are formed which are arranged in parallel across the board at an appropriate interval corresponding to the bending bending.

  The split groove 2 is a gap groove having a predetermined gap width, and the tip is formed into a V-shape 21a leaving a fractured portion 21 that breaks when the split groove 2 is expanded at the bottom reaching the surface side of the board 1, At the intersection with the radiating pipe laying groove 11, the dividing groove is interrupted and interrupted so as to cross the back surface of the board 1.

  A cutter notch 23 is provided at the intersection 22 with the laying groove where the split groove is cut off, and the cut surfaces 24a and 24b are separated along the bent side of the heat radiating pipe 13 corresponding to the expansion of the split groove 2. The base board 1 is refracted while supporting the intersecting portion of the heat radiating pipe corresponding to the entrainment of the base board 1.

  The warm water mat thus configured is wound with the surface of the board 1 facing inward using appropriate auxiliary equipment such as a winding core, so that the split groove 2 formed on the back surface of the base board is expanded on the outer surface. At the same time that the bottom fracture portion 21 of the groove is torn, the cut surfaces 24a and b of the intersection 22 with the radiating pipe laying groove 11 in which the cutter notch 23 is inserted are separated and slide along the flank of the laid heat radiating pipe 13 In addition, the hot water mat can be wound around a compact roll as shown in FIG.

  When the hot water mat packed in rolls is stored or transported to the laying site, the hot water mat is expanded and restored to its original shape at the site, and when the laid groove 2 is laid in the target room, the expanded split groove 2 is a groove. Since the cutter cut sections 24a and 24b that close and shrink to leave a width and form a smooth surface at the intersecting portion are restored to the close contact state, the split groove that once expands and breaks at the time of winding or the like has a gap with the radiating pipe laying groove. The gap between the radiating pipe laying grooves formed at the intersecting portion is also sealed, so that the release of air warmed by heat radiation can be prevented and stored in the laying radiating pipe to increase the thermal efficiency.

  Since the present invention is configured as described above, a mat that spreads in a rug shape and is bulky can be rolled into a compact roll, and excessive bending and refraction with respect to a heat-radiating tube inserted in a portion intersecting with a refracting portion at the time of winding is avoided. In addition, the heated air that has been released through the split groove can be stored in the radiating pipe laying groove to increase the thermal efficiency.
