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 floor heating hot water mats for residential use have been fitted with heat radiation pipes made of heat-resistant resin on the base board of expanded polystyrene (expanded polystyrene polymer) with piping path grooves, and heat radiation sheet on the top 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 address the above-described problems, and when folding the floor heating hot water mat, it is possible to avoid damage to the heat radiating pipe, the heat radiating sheet, and the corners of the board that are exposed to the fold. In this way, the base board is constructed by sequentially joining the connecting board that joins the upper end side of the base joist so that the valley can be folded at the joining portion at the lower end side of the base board, and the terminal board is wound up. It is constructed so that it can be folded on the base board one after another, and the contact surface part of the upper end side of the connecting board along the base board and the small joist is formed as a folding part, and it is wound up from the terminal board on the lowest side and folded. It is comprised as follows.

  In addition, when the floor heating hot water mat lays in a large area, a connecting board that joins the upper end side alongside the small joists that can be folded at the joint is sequentially joined to the lower end side of the base end board. The base board connected so as to be folded on the base board in order so as to wind the board is configured as a 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, a split groove is formed along the lower edge at the lower end of the back of each base board at a width corresponding to the overlapped thickness of the boards overlapped by folding. The overlapping thickness generated was included by bending the folding edge and the split groove, so that the parts and gaps that emerged depending on the thickness were wrapped.

  Furthermore, the dividing groove is a gap having a predetermined gap width, leaving a fractured portion that breaks when the dividing groove is expanded, and forming the tip of the gap in a V shape from the back surface to the surface of the hot water mat, In addition to facilitating the formation of a U-shaped bent portion that absorbs the overlapped thickness of the board, the shape of the curved portion is adjusted.

Embodiments of the present invention will be described below with reference to the drawings.
First, the embodiment of the single-type floor heating hot water mat shown in FIG. 1 will be described. Reference numeral 1 is a base board made of foamed polystyrene, starting from a heat delivery end 1p connected to the heat source connection port of the circulation port P on the surface. The two radiating pipe laying grooves 2 are engraved so as to be bent in a single stroke according to the pattern of the radiating pipe laying path so that the return terminal 2p is returned to the heat source connection port of the circulation port P for reheating. ing.
Of course, the radiating pipe laying groove 2 accommodates the radiating pipe 21 and is laid on the base board. Of course, the number of the radiating pipe laying grooves 2 is not limited to two but may be one.

  The base board 1 includes a base board 1a in which small joists 3 are fitted along the parallel heat radiating pipe laying groove 2a in the center from the side edge to the vicinity of the curved portion 2b of the heat radiating pipe laid groove 2 engraved as described above. A small board 3 and a connecting board 1b having a wider width than the base board 1a by fitting the side joist 4 to the side edge from the opposite end of the small joist to the vicinity of the curved portion 2b of the radiating pipe laying groove 2. 11b, the width of which is approximately half of each board, and the end boards 1c fitted with the same side joists 4 are sequentially arranged in parallel in the vertical direction.

  The parallel boards and the fitted small joists are joined only by the heat radiating sheet 5 stretched on the surface of the base board 1 after the heat radiating pipe 21 is accommodated in the heat radiating pipe laying groove 2. The split groove 6 formed on the back surface of the base board 1a is expanded when the bent portion that absorbs the overlapped thickness of the board is formed and the bottom of the groove is formed. Even if it is torn, the heat dissipation sheet 5 keeps the connection.

  The base board 1 configured as described above is folded so that the connection boards 1b and 11b are wound from the end board 1c with the surface inside, and is folded on the base board 1a. By expanding the split groove 6 formed along the lower edge of the lower end of the back surface of the base board 1a and folding the overlapped thickness of the board folded on the base board 1a as shown in FIG. The floor heating hot water mat can be folded. The dividing groove 6 does not need to be provided when the overlapping thickness of the board is small.

  7 and 8, the board units configured in the same manner as the base board 1 are connected side by side as 1A and 1B, and the adjacent board units 1A and 1B are joined to each other at the side portion of the base board 1a. The board unit 1A, 1B includes a base board 1a, a connecting board 1b, 11b, and a terminal board 1c arranged vertically in the longitudinal direction of each board. 1A and 1B are arranged side by side, and the base boards 1a and 11a between the two board units are joined to each other so that they can be bent with the back side facing inward at the side edges, and covered with a heat dissipation sheet 5 to form a base board 1 is configured.

  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 has a circulation port P, and a small and medium joist 3 is fitted along the parallel laying groove 2a in the center from the opposite end of the circulation port P to the vicinity of the curved portion 2b of the radiating pipe laying groove 2, and the lower end The upper end side of the connecting board 1 b is joined to the side so as to be bent by stretching the heat dissipating sheet 5. Further, the side of the proximal board 11a is joined to the opposite side of the circulation port P by a bendable folding structure with the back side inward.

  A side joist 4 is fitted to the upper end side of the connecting board 1b along the same side, and the side joist 4 is opposed to the medium joist 3 of the base board 1a and supports the base board 1 from both sides. Become. Further, the middle and small joists 3 are fitted along the central radiating pipe laying groove 2a of the connecting board 1b, and the upper end side of the connecting board 11b can be bent through the extension of the radiating sheet 5 at the lower end side 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 bendable 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 addition, in FIG. 9, before folding from the bottom, the base end boards 1a and 11a of the board units 1A and 1B are folded in a mountain shape and folded so that the ends of the units 1A and 1B are widened. However, this indicates 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 actually fold and polymerize. Sometimes it will be folded side by side, keeping it side by side.

  Since a split groove 6 is formed along the lower edge at the lower end portion of each base board where the width h corresponding to the overlapping thickness of the boards overlapped by folding is formed, each end board 1c, 11c The connecting boards 1b and 11b are folded so as to be wound on the base boards 1a and 11a, and then the split groove 6 is expanded and bent, and the board edges 1a and 1b and the boards 11a and 11b are folded. The overlapping thickness of the board overlapped by the U-shaped fold formed by the end edge and each split groove 6 is stored in the inner bottom part of each base board 1a, 11a lower end and the inner part of the widened split groove 6 for folding. The outer surface shape is adjusted.

  Further, the split groove 6 is a gap s having a predetermined gap width, leaving a fracture portion g that breaks when the split groove is expanded, and forming the tip of the gap in a V shape from the back surface of the hot water mat toward the surface. Thus, a 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.
