Description

  The present invention relates to a floor heating hot water mat constructed by arranging a plurality of boards in which reinforcing small joists are laid and laying heat radiation pipes in a foldable manner, and a folding method for packing this compactly. is there.

  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 floor heating hot water mat used in such a construction method is such that the heat radiating pipe laying surface of the base board is covered with a heat radiating sheet such as aluminum foil so that the heat is evenly distributed to the surface where the heat radiating pipe is laid. It is structured to combine multiple boards so that it is possible, but the heat radiating tube is sandwiched and fixed between the polystyrene foam and the heat radiating sheet constituting the board, and the heat radiating tube protrudes outside when folded, It is refracted and easily damaged.

  In order to cope with such a problem, a method of forming an accommodation groove in an oblique direction in which the heat radiating pipe is accommodated in the board when folded (see Patent Document 1) There is disclosed a method (Patent Document 2) in which a heat radiating pipe laying groove is provided on a board surface along a heat radiating pipe obliquely crossed in a tatami section.

Furthermore, the floor heating hot water mat is a baseboard placed on the floor and nailed to the small joists fitted to the board to fix the mat to the floor, and a plurality of small joists are installed on the board. The heat radiation pipes are configured to pass through the part where the small joist does not exist, leaving a part where the small joist does not exist in a part of the longitudinal direction of the radiating pipe, but the folding part for folding is small. A method (Patent Document 3) of forming along the longitudinal direction of small joists at a position away from the joists is disclosed.

  As described above, the folding portion for folding the conventional floor heating / hot water mat is formed at a position away from the small joists, and when the mat is folded, the corner of the board made of a relatively brittle material such as polystyrene foam is used. A corner portion or the like becomes an unprotected outer surface portion, and there is a problem that it is easily connected to a serious damage that is chipped off due to an impact during carrying.

  Also, in order to avoid the occurrence of floating parts and gaps due to the thickness of the board during folding, folding parts are provided in the connecting part of the board so as to fold alternately in the order of mountain folds and valley folds. There is a problem that the heat radiating tube protrudes from the outside when folded in the folding portion to be easily damaged.

  Furthermore, the pattern of the radiating pipe laying path starts from the heat source connection port of the circulating port formed on the base board, and one or more radiating pipe laying grooves are bent in a single stroke, and the end is again the heat source of the circulating port. Although it comes down to the connection port, the laying groove is bent on one base board constituting the mat to close the space between the parallel parts, and the radiating pipe laying groove is engraved with high density. It is difficult to maintain robustness, and it is necessary to reinforce by installing small joists in the center and reinforcing small joists that are intermittently connected to the upper and lower laying groove bends. There is.

The present invention is intended to respond to the challenges described above, when I tatami folding floor heating hot water mat, avoid heat radiation tube which is exposed to the folding part, damage to the heat dissipation sheet, the damage to the corners of the board as can, the proximal end board, constitutes a baseboard by joining one or more connecting boards having adjacent sides that沿設small joists to be valley fold in the adjacent sides, so as to involve the board terminal It can be folded on the base board.

Further, when the laying area of floor heating hot water mat is increased, the base end board, by joining one or more connecting boards valley fold capable of small joists having adjacent sides and沿設in the adjacent section, constituting the base board with connected tatami Mel so folded onto sequentially proximal board so as to involve the end board as the board unit.

  The board units are connected side by side, and adjacent board units are joined to each other at the sides of the base board to form a base board. The width of the unit board is folded by folding the connecting board from the end board, folding it on the base board, and then folding the base boards side by side, where the board units are stacked side by side. The floor heating hot water mat that has a wide width across the floor can be configured.

  By constructing the base board in this way, when the floor heating hot water mat is folded, the small joists (side joists) fitted to each board come to the folding side edge, and the radiator tube is installed. Since the end board is folded with the surface of the laid base board inside, and the connecting board is folded, it is folded on the base board so that the heat radiating pipe and the heat radiating sheet are wound inside the fold to be protected from external impact.

In addition, in a portion where the width corresponding to the overlapped thickness of the board overlapped by folding of the adjacent portion with the adjacent board on the back of each base board is formed, a split groove is formed in parallel with the adjacent joining edge, The overlapping thickness generated by folding the board during folding was included by folding the folding edge and the split groove so that the floating part and gaps were wrapped by the thickness.

Further, the split groove is formed as a gap having a predetermined gap width, leaving a fracture portion that breaks when the split groove is expanded, and the tip of the gap is formed in an inverted V shape that is reduced in width from the back surface to the surface of the hot water mat. In this way, the U-shaped bent portion that absorbs the overlapped thickness of the board is easily formed, and the shape of the curved portion is adjusted.

The board unit 1A, 1B includes a base board 1a, a connecting board 1b, 11b, and a terminal board 1c arranged in parallel along the longitudinal direction of each board. 1A and 1B are lined up side by side so that the center axes of the small joists match , and the base boards 1a and 11a between the two board units are joined so that they can be folded in the side part at the back side. The base board 1 is configured by covering with a heat dissipation sheet 5.

  On the surface of the base board 1, a heat radiating pipe laying groove 2 is engraved along a heat radiating pipe laying path pattern that circulates heat, and a heat radiating pipe 21 made of a heat-resistant resin is fitted in the laying groove 2 to each board. The heat radiation sheet 5 is stretched over the entire surface of the unit, and the boards are integrated as a unit by stretching the heat radiation sheet 5.

  As shown in FIG. 4 as an example, the laying path pattern of the heat radiating pipe 21 is formed on the surface of the base board 1 from the heat sending end 1p connected to the heat source connection port of the circulation port P to the outline of each unit board unit 1A, 1B. Recirculation termination by circulating heat along the two laying path patterns that circulate around the inner small joists 3 (medium small joists) and side small joists 4 in a single stroke, and then sequentially circulate around the inner shell and circulate to each stage of the unit. 2p is set so as to return to the heat source connection port of the circulation port P again for reheating, and is set in a substantially parallel parallel state except for a bent portion for circulation.

  Further, the curved portion 2b of the radiating pipe laying groove 2 is formed so as to be oblique to the joining edge of each board to be connected, and further, the intersection of the radiating pipe 21 laid and fitted in the board bent portion. The part laying groove is formed into a widening groove 23 having a larger volume than the other fitting parts, and is inserted into the groove so that the distortion stress of the heat radiating pipe 21 caused by bending the board is released to the blank space and absorbed. It is configured so that an unreasonable burden is not applied to the heat radiating pipe 21 by folding.

The proximal board 1a is located at a predetermined end, and includes, for example, a heat source connection port P, and extends along the parallel laying groove 2a in the center from the opposite end of the heat source connection port P to the vicinity of the curved portion 2b of the radiating pipe laying groove 2. small joists 3 are fitted, the adjacent edge of the board 1b which is connected to the proximal end board 1a adjacent sides of the connecting board 1b is bendable joined by stretched heat dissipation sheet 5 Te. Further, on the opposing sides of the heat source connection port P side of the base board 11a is joined to the mountain fold possible bent structure was back surface inward.

A side joist 4 is fitted along the same side of the connecting board 1b with the base board 1a. The side joist 4 faces the middle board 7 of the base board 1a and faces the base board 1a. It will be a form that supports. Furthermore, the connecting board 1b small joists 3 along a central portion radiator pipe laying groove 2a of the fitted, stretched adjacent sides of the heat radiation sheet 5 of the connecting board 11b in the adjacent edge of the connecting board 11b of the connecting board 1b The end board 1c, in which the side joists 4 are fitted along the upper side, is joined to the lower side of the connecting board 11b so as to be bent through the stretching of the heat dissipating sheet 5.

  The side joists 4 of the end board 1c are opposed to the medium joists 3 of the base board 1a and support the base board 1 from both sides. The side joist 4 is disposed along the side edge of each board as a reinforcement of the corner when folded, but the medium joist 3 is appropriately disposed according to the size of each constituent board. is there.

  In order to fold the connected floor heating hot water mat configured as described above for transportation or the like, as shown in FIG. 9, the board unit 1 </ b> A joined side by side at the side portion of the base board. And 1B are bent at an appropriate angle, the end boards 1c and 11c are sequentially bent with the surface facing inward, and the connecting boards 1b and 11b are folded so as to be wound on the base boards 1a and 11a, and then each board unit is folded. The side-by-side baseboards 1a and 11a that are subjected to tatami-polymerization are folded with the back side facing inward.

In relation shown in FIG. 9, before'll folded from the distal side base end board 1a of the board units 1A and 1B, 11a and in the crease unit 1A, folded to wind in a state in which it spreads the tip of 1B This shows that the units 1A and 1B are joined only at the sides of the base boards 1a and 11a, and that the other parts are separated and separated, and when actually folded and polymerized. Is folded from the end side in a side- by -side state.

A split groove 6 is formed in parallel with the edge of the adjacent portion at a portion where a width h corresponding to the overlapped thickness of the boards overlapped by folding of the adjacent portion of the back surface of each base end board is connected to the connecting board. Therefore, the end boards 1c and 11c are sequentially bent and folded so that the connecting boards 11b and 1b are wound on the base board 1a, and 13b and 12b are wound on the top 11a, and then the split groove 6 is expanded and bent. The outer surface shape of the folding is adjusted by storing the overlapped thickness of the board overlapping the U-shaped folding part formed by the board edge of 1a, 1b, the board edge of 11a, 12b and each split groove 6 .

Further, the split groove 6 is a gap s having a predetermined gap width, leaves a broken portion g that breaks when the split groove is expanded, and has an inverted V-shape that narrows the tip of the gap from the back surface of the hot water mat toward the surface. Thus, the U-shaped bent portion that absorbs the overlapped thickness of the board is easy to form, and the shape of the curved portion is also adjusted.

  The hot water mat folded and packed as described above is stored or transported to the laying site as it is, and can be easily restored to its original form by spreading the hot water mat in the reverse procedure to the above procedure. When laying indoors, the expanded split groove 6 is closed and contracted leaving the groove width, and is restored to the original state before folding, so that damage to the board or the like due to folding can be kept to a minimum.

  Since the present invention is configured as described above, a mat that spreads in a rug shape and is bulky can be folded in a compact manner, and excessive bending and refraction with respect to a heat-radiating tube inserted in a portion intersecting with a refracting portion when folding is performed. Can be avoided, and the small side joists are reinforced at the corners of the board that appear on the outer surface by folding, so that a robust folding configuration can be achieved.
