Description

  The present invention provides a solid flooring support panel for floor heating that adds a floor heating function by supporting a solid wooden floor material formed on a large pulling material from under the floor, and a solid flooring support panel for floor heating. The present invention relates to a floor heating system including a plurality of sheets and configured on a large drawing material.

  As a floor heating system for a double floor in a floor structure constructed on a large pulling material and joists, conventionally, a floor flooring material is directly fixed on the large pulling and a thin flooring material is constructed thereon. The This flooring material is made of a solid flooring material, which eliminates the need for joists and heat insulating materials. Moreover, the groove | channel which accommodates the pipe for heating is given on the upper surface, and the piping corresponding to the condition of the field shall be performed (for example, refer patent document 1).

In addition, as a conventional floor heating structure, a floor base panel is laid out on a floor base such as a concrete slab via support legs, a finishing material is provided on these floor base sub-nels, and between the finishing material and the floor base panel. A hot water panel is arranged, and the floor base panel is laminated and integrated with a heat insulating material made of a plastic foam between two particle boards, which are plate materials. Is known (for example, see Patent Document 2). This is done by supporting the floor basement panels laid next to each other at one corner of a common backing plate, and horizontally supporting the center of this backing plate on the concrete slab by support legs with cushion rubber at the lower end. It is supposed to be.

  However, the former flooring material is expensive because it consists of a single solid material, and it is said that joists and heat insulation materials are unnecessary. In addition, there was a limit to the heat insulation performance.

  In addition, although the upper and lower plate materials and heat insulating materials of the latter floor base panel can ensure a predetermined heat insulating property by a multilayer structure, each component material is made of a single panel-sized integrated lumber, so warpage occurs due to the difference in the amount of expansion and contraction. Or interlayer separation may occur. In particular, when mounting directly on a large pulling material like the former, moisture permeability or heat transfer changes between the mounting part and other parts, and warpage and interlayer separation are emphasized at the gaps between the panels. It will be done.

  Therefore, the present invention is a solid flooring support panel for floor heating placed directly on a large pulling material, which is relatively inexpensive and excellent in heat insulation performance, but it is free from warpage and interlayer separation due to material expansion and contraction. It is an object of the present invention to provide a device that can suppress the occurrence.

Means (1) to (6) are taken to solve the above problems.
(1) The solid flooring support panel for floor heating of the present invention is
A plurality of pieces are laid over a plurality of large-drawing materials O that run under the floor, a heating pipe T for heating the wooden flooring F is embedded in the upper part, and the wooden flooring F is laid thereon. A solid flooring support panel for floor heating that can support the wooden flooring F from the back side so that it can be heated,
A cover plate 1 having a predetermined pattern of tube grooves 1d in which the heating tube T can be embedded is formed at the top, and one and other side connection structures 1t and 1m for the adjacent other plates are formed on the one and other sides, respectively. When,
A plurality of linear support squares 2 fixed at a predetermined interval below the lid plate 1;
A clogging plate 3 having a heat insulating function, which is fixed within a predetermined interval of the plurality of support square bars 2;
The bottom plate 4 fixed to the lower part of the support square bar and covering the lower part of the whole panel including the support square bar 2 and the filling plate is connected and configured.
The lid plate 1 includes a plurality of lid members 10 made of a solid material having tenon connection structures 10t and 10m at the center heights of both side portions, and each of the lid plates 1 is coupled to each other in the lateral direction in plan view and has a support angle. Fixed to bar 2,
The bottom plate 4 includes a plurality of bottom constituent members 40 made of a solid material having a thickness smaller than that of the lid constituent member 10 and are arranged side by side in the same horizontal direction as the lid constituent member 10 in parallel with each other. It is characterized by being fixed to the rod 2.

(2) Or the solid flooring support panel for floor heating of the present invention is laid over a plurality of large-drawing materials O that run under the floor, and a plurality of laying panels are laid on top to heat the wooden flooring F. A solid flooring support panel for floor heating which can support the wooden flooring F from the backside by laying the wooden flooring F across the warm sheet S,
A lid plate 1 that can hold the heating sheet S on the upper surface and that has one and other side connection structures 1t and 1m formed on one side and the other side of the adjacent other plate,
A plurality of support square bars 2 fixed at a predetermined interval below the lid plate 1;
A clogging plate 3 having a heat insulating function, which is fixed within a predetermined interval of the plurality of support square bars 2;
The support square bar and the bottom plate 4 that collectively cover the lower part of the filling plate are connected and configured.
The lid plate 1 includes a plurality of lid members 10 made of a solid material having tenon connection structures 10t and 10m at the center heights of both side portions, and each of the lid plates 1 is coupled to each other in the lateral direction in plan view and has a support angle. Fixed to bar 2,
The bottom plate 4 includes a plurality of bottom constituent members 40 made of a solid material having a thickness smaller than that of the lid constituent member 10 and are arranged side by side in the same horizontal direction as the lid constituent member 10 in parallel with each other. It is characterized by being fixed to the rod 2.

  As in the above (1) and (2), a part of the connecting side surfaces of the connected lid constituent materials 10 by connecting the multiple lid constituent materials 10 at the center position of the height of the lid constituent materials 10 Even when a slight gap is generated, the connected state can be maintained. In addition, since the support square bar 2 is connected to the bottom of each lid component 10, distortion deformation itself of the lid component 10 is limited to the support square bar. Here, even if a strain deformation external force due to the cover component 10 is applied to the support square 2, the support square 2 itself is not deformed due to the external force balance with the bottom component 40, and the support square 2 is in a straight state. Can keep.

  That is, when a strain deformation external force due to the lid component 10 is applied to the support square bar 2, a plurality of butted bottom components 40 are connected to the lower part, and the bottom component 40 has a strain deformation larger than that of the lid component 10. Occurs. Then, an external force having a larger strain deformation amount due to the bottom constituent member 40 is applied to the upper portion of the support square rod 2 and the lower portion of the support square rod 2 in a distributed manner. As a result, the upper external force by the lid constituent member 10 is canceled by the lower external force by the bottom constituent member 40, and the external force applied to the support square bar 2 is balanced. As a result, at least the influence of the distortion of the lid component 10 is suppressed, the upper panel is not warped or deformed, and the overall shape of the panel is maintained without distortion regardless of changes in temperature and humidity. Can do.

  Thereby, a part of the warp and distortion of the cover constituent material 10 caused by the change in humidity and temperature is absorbed, and the distortion and warpage of the cover plate 1 do not appear greatly in the entire panel width in the entire connection direction.

  In particular, the adjacent lid constituent members 10 may be connected to each other without being bonded by an adhesive, and the adjacent bottom constituent members 40 may be juxtaposed in a contact state without being bonded by an adhesive. preferable. Since the bottom constituent members 40 are provided together by abutment and are not connected to each other, the external force due to distortion deformation of the bottom constituent members 40 is not accumulated at both ends of the panel, and the external force due to the deformation of each bottom constituent member 40 is not accumulated. Takes distributed.

  In addition, the intermediate layer sandwiched between the upper layer composed of a plurality of lid constituent materials and the lower layer composed of a plurality of bottom constituent materials is filled with an integral plate, and this three-layer structure is as described above. By maintaining the overall shape of the panel without distortion, it ensures a reliable insulation function regardless of changes in temperature and humidity. In particular, when the panel is heated by the heating tube T, each bottom constituent member 40 in the lower layer expands, and the butt force to the adjacent bottom constituent member 40 increases, so that heat radiation to the lower side of the panel is more reliably blocked. Will be. On the other hand, when the panel is relatively low temperature or dried, each bottom constituent material 40 in the lower layer contracts, the butt force to the adjacent bottom constituent material 40 is reduced, and a gap is partially generated. A certain amount of heat can be taken by aeration from the lower side. This is a characteristic mechanism in the floor heating system of the solid flooring support panel for floor heating that lays and connects over the large pulling material O, even if the bottom constituent material on the lower surface of the panel is warped and separated, Since the entire panel is fixed over the large pulling material O and the panels are connected to each other at the upper part in the height direction, the balance of internal stress can be maintained throughout the floor without the panel floating. .

(3) In the solid flooring support panel for floor heating according to any one of the above, the lid constituent material 10 and the bottom constituent material 40 are both paneled boards that have been subjected to graining in the longitudinal direction along the grain.
The lid plate 1 is composed only of an upward lid constituent material 10 in which the surface side of the plate is the upper surface of the panel,
It is preferable that the bottom plate 4 is composed only of a downward bottom constituent member 40 having the front side of the plate as the bottom surface of the panel.

  The plate is warped from both ends with the surface side being concave as the temperature and humidity conditions change repeatedly and over time. Therefore, as described above, all the panel plates of the plurality of lid constituent members 10 are configured in the same direction, and all the panel plates of the plurality of bottom constituent members 40 are in the opposite direction to the lid constituent member 10. When configured in the direction, the lid plate 1 is deformed so that both ends in the width direction of the lid constituent material connected to the entire panel are warped toward the panel surface side, and the bottom plate 4 is in the width direction of the bottom constituent material 40 arranged in parallel across the panel Each end is deformed so as to warp toward the back side of the panel (see FIG. 3). In other words, the cover component 10 of the front surface layer and the bottom component material 40 of the back surface layer are warped and deformed in the opposite directions. At this time, the bottom component material 40 thinner than the cover component 10 is warped and deformed more greatly. Here, since the lid component 10 and the bottom component 40 are fixed with the support square bar 2 interposed therebetween, the warp deformation amount of the lid component is offset by the larger warp deformation of the bottom component.

  In particular, as shown in FIGS. 2 and 3, it is preferable that the lid component 10 and the bottom component 40 are fixed to each other with the same width and overlapping the same position in plan view. Thereby, since the location where warp deformation occurs is the same in each of the upper and lower components (FIG. 3), the warp deformation of the lid component is always suppressed at the same position in plan view below, and the deformation of the lid component 10 is suppressed. As a whole, the deformation of the cover plate 1 is suppressed.

  In the panel in which the heating tube T is embedded, as shown in FIGS. 1 to 4, a tube groove 1 d is formed along the vertical direction of the grain at the center position in the width direction of the upper surface of each of the skull components 10. It is preferable. By embedding one heating tube T at a central position in the width direction, thermal deformation by the heating tube T becomes symmetrical in each lid component 10 and the deformation amount is balanced between the connected lid components 10. (See FIG. 3). For this reason, the deformation amount is not biased, and the biased distortion is less likely to occur in the entire panel or the entire system in which a plurality of panels are combined.

  (4) In the solid floor material support panel for floor heating according to any one of the above, the one and other tenon connection structures 1t and 1m formed on both side ends, and the tenon connection structures 10t and 10m of the lid component 10 It is preferable that they have the same shape and are formed at a common height above the upper third of the entire panel. If the hozo connection structure is above the upper third of the thickness of the entire panel, the remaining two-thirds of the thickness below the hozo connection portion will firmly tighten the entire lid 1 from below. To prevent the warp deformation of the lid component 10.

(5) In any one of the above-described solid floor heating support panels for floor heating, the support square bar 2 has a frame member 21 framed along the periphery of the panel in plan view, and the inner sides of the frame member 21 vertically or horizontally. And a cross member 22 fixed in a cross direction,
It is preferable that the filling plate 3 is fitted into each of a plurality of filling spaces formed between the side surfaces of the frame member 21 and the cross member 22 with a predetermined filling gap.

  As described above, the filling plate 3 is formed to be slightly smaller than the filling space, and is fitted with a filling gap, so that the influence of the filling plate 3 on the distortion deformation of the panel is eliminated, and the lid constituting material and the support square bar It is possible to maintain the heat insulating function of the filling plate 3 while maintaining the balance of deformation of other panel constituent materials such as the bottom constituent material. Further, by taking an air layer around the filling plate by the filling gap, a more excellent heat insulating function can be achieved.

  (6) And the floor heating system of the present invention lays the solid flooring support panel for floor heating described above on the large pulling material O without any gaps in the vertical and horizontal directions when viewed from above. The solid flooring is formed by laying and connecting the grooves in the longitudinal direction in a plan view intersecting with the lid constituting material.

More specifically, the floor heating system of the present invention is
-Solid floor material support panel P for floor heating according to any one of the above, wherein a plurality of sheets are laid without gaps across a plurality of large draw materials O running under the floor,
A heating tube T or a heating sheet S embedded in the tube groove 1d or the frame groove 1d of the solid flooring support panel P for floor heating and laid across the upper surface of the plurality of panels;
A wood floor material F laid and formed on a solid floor material support panel P for floor heating in which a heating pipe T is embedded,
The wooden flooring F has a vertical direction in plan view in which a plurality of floor constituents F0 made of solid materials having connecting structures Ft and Fm at the center heights of both side portions intersect with the connecting direction of the lid constituent 10. It is one that is connected to each other.

  By taking the above measures, the present invention is relatively inexpensive and has excellent heat insulation performance in a solid floor support panel for floor heating placed directly on a large pulling material or a floor heating system provided with this. However, it is possible to provide a material that can suppress the occurrence of warpage due to material expansion and contraction and the occurrence of interlayer separation.

  The best mode for carrying out the present invention will be described below with reference to the drawings showing embodiments. First, FIG. 1 thru | or FIG. 5 shows the solid flooring support panel for floor heating of Example 1. FIG. Specifically, FIG. 1 is a partially broken perspective view showing an installation state of a solid flooring support panel for floor heating in Example 1, and FIG. 2 is a sectional view of only the panel (cross section taken along line AA in FIG. 4). 3 is an enlarged cross-sectional view of one end portion of the panel in a warped state, FIG. 4 is a partially broken plan view of the panel, and FIG. It is plane explanatory drawing which shows the construction state of the floor heating system which combined the panel of the form which was spread over the whole room. Next, FIG. 6 shows a partially broken perspective view of the solid flooring support panel for floor heating of the second embodiment in which two pipe grooves 1d are formed for each lid component 10. FIG. 7 shows a partial cross-sectional view of the installation state of the solid flooring support panel for floor heating of Example 3 in which the tube groove 1d is not formed and the heating sheet S can be framed instead on the upper surface.

The solid flooring support panel for floor heating of the present invention is laid with a plurality of hoses connected to each other across a plurality of large pulling materials O running under the floor of a solid wood flooring F (for example, flooring floor). In addition, the flooring can be supported by the heating means embedded in the upper surface (for example, the heating tube T or the heating sheet S) so that the temperature can be adjusted. As its configuration,
A structure for incorporating a heating means capable of heating the wooden floor material F from the lower surface is provided at the upper part, and a side connection structure for connecting to an adjacent other plate (specifically, a connection type protrusion 1t that can be connected) And a groove 1m)) on both sides of the lid plate 1,
A plurality of supporting square bars 2 fixed at a predetermined interval below the lid plate 1;
A filling plate 3 having a heat insulating function, which is fixed by filling within a predetermined interval between the support square bars;
-It is comprised from the bottom plate which covers a support square bar and the lower part of a filling board. Hereinafter, each configuration will be described in detail.

(Cover plate 1)
The cover plate 1 constitutes the upper layer part of the integral multi-layer structure of the panel, has a structure for incorporating the heating means on the upper part thereof, and is adjacent to both side parts of the cover plate 1. It has a fitting structure for connecting to other panels.
When the heating means is a heating tube T (FIG. 5) such as a polybden hot water pipe, the structure for incorporating the heating means refers to a tube groove 1d drilled in the upper surface for embedding this, When the heating means is a heating sheet S (FIG. 7) such as an aluminum electric sheet, it means a frame holding space provided for holding the frame on the upper surface.

  The structure of the cover plate 1 is not a single piece of integrally produced lumber, but a plurality of cover constituent members 10 made of thick solid wood boards having connecting structures 10t, 10m at the center heights of both sides. They are composed of coupling plates that are coupled to each other in the horizontal direction in plan view. The lid constituting material 10 is a thick plate made of lumber with the longitudinal direction along the grain as the longitudinal direction, and cedar, cocoon, etc. are adopted. Each of the lid-constituting members 10 of the plate is arranged in parallel upward with the surface side as the upper surface of the panel (FIG. 1).

(Hozo connection structure and connection screw fixing structure)
One and other tenon connection structures 1t and 1m are formed on the lid constituent members 10 on both sides located at one end and the other end of the panel, respectively, for connecting to other adjacent panels. Further, on one side portion and the other side portion of the plurality of lid constituent members 10 other than the both end sheets, that is, in the central portion, tenon connecting structures 10t and 10m are formed to connect to the adjacent lid constituent members 10 respectively. The Specifically, the one and other tenon connection structures 1t and 1m are composed of prismatic ridges and ridge grooves into which the ridges can be fitted. These one and other tenon connection structures 1t and 1m and the tenon connection structures 10t and 10m of the lid component 10 have the same shape, and both are formed at a common height in the center in the height direction of the lid component 10. Is done. By being connected at the central height of the common lid component 10, distortion deformation amounts such as a lid shrinkage width 10 tl and a lid warp width 10 wp when the lid component 10 warps are generated based on the height of the side coupling. (FIG. 3).

  In addition, when the lid constituent material 10 is along, a lid gap portion 10g is formed near the upper portion between the adjacent lid constituent materials 10, but the lid gap portion 10g is located at the upper portion when the configuration is connected in the vicinity of the center height. When it is generated in the vicinity, the vicinity of the lower part between the adjacent lid constituent members 10 comes in contact with each other and presses each other, and the size of the generated lid gap portion 10g is limited (FIG. 3).

  Further, the cover constituent members 10 that are connected to each other are also connected in the thickness direction to the lower support square bar 2 and the filling plate 3 when the fixing screw 5 is threaded through from below (see FIG. 2 to FIG. 2). FIG. 4). In particular, as in Example 1, the surface side of each lid component 10 of the plate is installed with the upper side facing upward, and the vicinity of both ends of this upward lid component 10 is integrally formed with the fixed screws 5, thereby fixing the screws. 5 suppresses upward warping, and the amount of distortion deformation generated such as the lid shrinkage width 10 tl and the lid warpage width 10 wp is small (FIG. 3).

  These tenon connection structures 1t, 1m, 10t, and 10m are all preferably formed at a position higher than half of the entire panel thickness, that is, at a common height above the upper third. 2). If the teno connecting structure 1t, 1m, 10t, 10m is above the upper third of the total panel thickness, the remaining two thirds of the thickness below the hozo connecting part The base portion becomes heavier, and the warp deformation of the cover plate 1 is also suppressed by the static rigidity of this portion.

(Supporting square bar 2)
The support square bar 2 is composed of a frame member 21 that is framed along the periphery of the panel in plan view, and a cross member 22 that is transversely fixed to the inside of the frame member 21 in the vertical or horizontal direction. The support square bar 2 is constituted by a frame connection screw 33 for fixing the frame member 21 to the frame and a frame connection screw 33 for fixing the cross member 22.

  The cross member 22 is fixed orthogonally to the frame member 21 at a position where the sides of the panel are equally divided, and is appropriately provided depending on the size of the frame member 21 and the thickness of the floor board 1. For example, in the first embodiment, there are a transverse member 21 in the transverse direction that crosses the centers of the vertical sides in plan view, and a transverse member 22 in the longitudinal direction that runs vertically in the centers of the horizontal sides in plan view and crosses the transverse members 21 above and below, respectively. Provided (FIG. 4). The support square bar 2 plays a main role in static holding of the panel shape based on its own static rigidity even when the lid plate 1 and the bottom plate 4 are warped and deformed (FIG. 3). A connecting screw for connecting each layer of the panel is driven at predetermined intervals along the length direction of the support square bar 2, and the frame member 21 and the cross member 22 form a filling space for fitting the filling plate. (FIG. 4).

(Filling board 3)
The clogging plate 3 is a wooden laminated material that is clogged and fixed within a predetermined interval of the plurality of support square bars 2 and has a heat insulating function and a heat retaining function. The filling plate 3 is fitted into each of a plurality of filling spaces formed between the side surfaces of the frame member 21 and the cross member 22 of the support square bar 2 with a predetermined filling gap. The planar shape and thickness are slightly smaller than the space between the support square bars, the planar shape and thickness, and have a predetermined filling gap in advance between the lid constituent material 10 group and the bottom constituent material 40 group. After being fitted, it is penetrated and fixed in the thickness direction by the fixing screw 5 from the back surface (FIG. 4). By providing a predetermined filling gap in advance, the support square bar, the cover plate 1 and the bottom plate 2 are not obstructed from distortion deformation, and an air layer is interposed between the fill plate 3 and the support square bar 2. To increase the heat insulation effect. Although various materials are used as the heat insulating material, it is preferable to use an insulation board in which natural wood is assembled without using plastic foam, hard glass wool, or hard rock wool.

(Bottom plate 4)
The bottom plate 4 collects the lower portions of the support square bar 2 and the filling plate 3 and covers the entire panel. Like the cover plate 1, it is not composed of a single piece of integrally produced lumber, but a plurality of bottom constituent members 40 having the same planar shape as the cover constituent member 10 and thinner than the lid constituent member 10 are They are arranged side by side so as to be in close contact with each other in the same horizontal direction as the component 10 in a plan view. The bottom constituent member 40 is a thin plate plate that is thinner than the lid constituent member 10 and is manufactured by using the vertical direction along the grain as the longitudinal direction. In order to facilitate the adjustment of the balance of the deformation amount of the entire panel, it is preferable that the same lumber as the lid constituent material 10 such as cedar and cypress is adopted. The bottom constituting members 40 of the plate are arranged in parallel downward with the front side as the lower surface of the panel (FIG. 1).

  The plurality of bottom constituent members 40 are fixed only to the upper support square bar 2 or the filling plate 3 by fixing screws 5 penetrating in the thickness direction. Adjacent bottom constituent materials are arranged in parallel with each other in a state of being in close contact with each other without being connected. Due to the stratification and fixing on the upper surface side and the separation in parallel, the bottom shrinkage width 40tl and the bottom warp width 40wp when the bottom constituent member 40 warps are generated with reference to the upper surface of the bottom plate. Here, since the bottom constituent member 40 is made of a solid wood plate that is thinner than the lid constituent member 10, the bottom constituent member 40 has a larger deformation amount than the deformation amount of the lid constituent member 10 (FIG. 3). . That is, in FIG. 3, the bottom shrinkage width 40tl and the bottom warp width 40wp are larger than the lid shrinkage width 10tl and the lid warp width 10wp, respectively, and therefore, the lower bottom constituent material is larger than the internal moment due to the deformation of the upper lid constituent material 10. The internal moment due to the deformation of 40 becomes larger (see the arrow in FIG. 3).

  Further, since the bottom constituent members 40 of the lower layer are separated from each other, the reaction force toward the upper layer side is generated in a distributed manner for each bottom constituent member 40. Thus, although the stress that does not deform for each bottom component 40 is relatively large, the internal stress does not accumulate depending on the position in the width direction of the bottom component 40 in the entire panel, and the plurality of bottom components 40 are approximately the same. A uniform internal stress is generated. For this reason, the whole panel does not warp and deform downward due to the warping stress of the bottom constituent member 40 made of a downward plate.

(Fix each component)
The fixing in the manufacture of the panel is performed only by the frame connecting screw 23 for connecting the support square bar 2 to the frame and the fixing screw 5 for fixing the upper layer, the middle layer and the lower layer from the back surface. Specifically, as shown in FIG. 4, the frame connecting screw 23 is used by striking the frame members 21 substantially horizontally from the side of the panel at the four corners of each side of the panel, and crossing the frame member 21 at the center of each side of the panel. The material 22 is used by striking from the side of the panel. As shown in FIGS. 2 and 4, the fixing screw 5 is a pair of cylinders at symmetrical positions near both ends of the lid constituting plate 10 and the bottom constituting plate 40 that are overlapped at the same position in plan view, from the back side of the panel toward the surface. Used by striking substantially vertically.

The panel is fixed to the large pulling material O in the construction of the floor heating system by driving a fixing nail from the upper surface of the panel (not shown). Panels are connected only by a side-to-side connection structure, and no screws or other fixtures or adhesives are used.
These all consist only of screws or nails. In the panel manufacturing process and in the construction stage of the floor heating system, the bonding function is deteriorated by the synthetic material because no adhesive is used in the process of connecting the panels to each other and the process of straddling the large pulling material O. , Can prevent the generation of odor. In addition, the strain deformation can be automatically dealt with by the balance of the internal stress of the panel.

  The solid flooring support panel (FIGS. 2 to 4) for floor heating in the floor heating system (FIGS. 1 and 5) of Example 1 includes 10 lid members 10 and 10 bottom members 40 of the same width. Are configured as an integrated panel with the support square 2 and the filling plate 3 interposed therebetween. Each lid component 10 is formed with a single rectangular cross-section tube groove 1d at the center position of the upper surface width at the same depth along the longitudinal direction of the plate, and the heating tube T is embedded therein. .

  Since one heating tube T is embedded at the center in the width direction, the temperature effect by the heating tube T is evenly generated on both sides with the center portion in the width direction of the lid constituting material 10 as the center. For this reason, the distortion near the both ends of the lid component is suppressed as much as possible.

  The heating pipe T is a parallel running pipe with the forward pipe T1 and the return pipe T2 being adjacent to each other, and two lid members are provided at the end in the length direction (upper and lower ends in FIGS. 4 and 5). It is connected to the cover constituent material next to the sheet, and the direction is changed in the opposite direction (FIG. 5). For example, at the end in the length direction, the first outward pipe T1 is greatly bent at the bend and is disposed in the tube groove 1d of the outward pipe T1 of the fourth lid component 10, and the third The return pipe T2 is relatively bent at the bend and is disposed in the pipe groove 1d of the return pipe T2 of the second lid component 10 (FIGS. 4 and 5).

(Floor heating system of Example 1 of the present invention)
Plural types of patterns with different tube grooves 1d are prepared in the plurality of panels of Example 1, and these plural types of panels are combined and spread over the large drawing material O of the entire room, and the heated tube is placed in the tube groove 1d. The floor heating system according to the first embodiment of the present invention is configured by embedding T, piping back and forth, and connecting to the water heater H (FIG. 5).

Specifically, as shown in FIG. 5, the configuration of the floor heating system of Example 1 is a first panel 1 </ b> A in which the upper part on the left side and the entire lower side are adjacent to the heating pipe T in plan view, The second panel 1B having the upper right side and the entire lower side as the adjacent communication port of the heating tube T, the third panel 1C having the entire upper side as the adjacent communication port, and the entire upper side as the adjacent communication port. A fourth panel 1D that houses both the reciprocating heating tubes T in the communication hole 6 and is arranged at one corner portion, and a fifth panel 1D that uses the entire upper and lower sides as adjacent communication ports, Connect and lay in combination with each other in the vertical and horizontal directions and changing the direction as necessary.
The adjacent communication port refers to a communication port for connecting a heating tube to an adjacent panel, and the adjacent communication ports are in contact with each other at the same position on the adjacent panel, so that they pass through the portion of the tube groove 1d. The warm pipe T is piped so as to straddle the adjacent panel.
