The edge and / or side edge of the floor heating panel 1 is formed into a vertical and flat end surface and side surface, and is formed so as to interconnect or interconnect adjacent floor heating panels 1 in a butt type or a butt type. Not only can it be obtained, but as shown in FIG. 7 (A), it can be formed into a so-called step joint type end face or side face provided with step portions 18 and 19. In FIG. 7A, the step portion 18 and the step portion 19 are
The complementary shapes are formed. By appropriately adjusting the dimensions of the step portions 18 and 19, it is possible to compensate a construction error or a product error related to the connection or connection between the adjacent floor heating panels 1 and narrow the gap between the floor heating panels 1. It will be possible. Also, by adjusting the dimensions of the step portions 18 and 19,
Not only a gap capable of absorbing thermal expansion / contraction of the floor heating panel 1 can be secured in the area between adjacent panels, but also the step portions 18, 1

Can be installed at So-called wood or ruler members 21, 23 having halves that can be accommodated in the grooves 20, 22 are interposed in the area between adjacent panels. Arbor members 21, 23 extending along the grooves 20, 22
The cross-sectional dimension of is set to be slightly smaller than the inner dimension of the hollow portion between panels formed by the opposing grooves 20 and 22.
Similar to the construction example shown in FIG. 7A, such a groove 20,
By arranging 22 and the wood members 21 and 23, the gap between the panels is narrowed and the gap capable of absorbing thermal expansion and contraction is formed.
Furthermore, the floor heating panel 1 can be prevented from warping, bending or deforming.

As shown in FIG. 8, the floor heating panel 1 having the reference pattern shown in FIG. 4 is sequentially laid or laid in a predetermined floor heating construction area. A plurality of (six in this example) floor heating panels 1 laid over the entire floor heating construction area are distributed over the entire construction area by the above-described first groove 14 and second groove 15 (FIG. 4). A continuous groove is formed on the floor surface. The continuous groove is
A first continuous groove extending in the longitudinal direction over the entire length of the floor heating construction area and a second continuous groove extending in the width direction over the entire width of the floor heating construction area are formed. The pipes are laid along the first continuous grooves formed by the first grooves 14 (FIG. 4), and the second grooves 15 (FIG. 4) are respectively arranged at both ends of the floor heating construction area.

The take-out portion E1 of the pipe P is connected to a hot water outflow pipe (not shown), and the pipe P
The take-out part E2 is connected to the hot water return pipe. The hot water outward pipe is connected to a heating source such as a boiler via a hot water pressure pump or the like (not shown), and the hot water return pipe is connected to a hot water recirculation means or a reflux water reservoir connected to the heating source. . The supply hot water SW heated by the heating source is supplied to the take-out part E1 by a hot water pressure pump or the like, circulates in the hot water pipe P, and serves as reflux hot water RW to the hot water reflux means via the take-out part E2 and the hot water return pipe. To return.

The pipe system P thus constructed has only a comparatively small number of bends or bends B, and does not have a pipe connection in the inter-panel region, and therefore the hot water flow resistance. Alternatively, the flow resistance can be reduced, the capacity of the hot water pressure pump, etc. can be reduced, and the construction work of the piping can be simplified. Further, according to the construction method using the floor heating panel 1 described above, the piping foundation work by laying the floor heating panel 1 standardized and manufactured in a factory and the piping for the continuous groove for piping formed in the construction area Since the construction of the floor heating equipment can be substantially completed by the laying work of P, not only can the construction of the floor heating equipment be standardized and accurate, but also the work process of the floor heating equipment can be greatly simplified. can do. Furthermore, the floor heating panel 1 laid in the entire construction area forms continuous grooves that are standard and evenly distributed in the entire construction area by the first continuous groove and the second continuous groove. Since a person can determine the piping route relatively freely, the degree of freedom in designing and constructing the piping is greatly improved. That is, in the floor water heating system of the hot water panel type having the above-mentioned configuration, the conventional layout designing and constructing the floor heating panel by determining the piping layout or the piping route with each floor heating panel as a unit and combining the floor heating panel as desired The method of construction was abandoned, and continuous grooves with a standard pattern extending over the entire construction area of the floor heating equipment were distributed throughout the construction area, and the entire construction area or the entire room where such a group of standard continuous grooves was formed was As a unit, the piping layout or the piping route is determined, and the floor heating piping is designed and constructed. Therefore, according to the above configuration, generalization or standardization / standardization of the floor heating panel can be realized. In addition, it is possible to undertake piping foundation work for floor heating equipment and division of piping work. Further, by using the floor heating panel 1 having the above-described configuration, the floor finishing material or the floor base material to be arranged on the heat storage body 12 can be designed to have a relatively free size or material, which is practical. Is extremely advantageous to

The floor heating panels 1 are successively laid or packed in the heating construction area, and the plurality of floor heating panels 1 form continuous grooves distributed over the entire construction area on the floor surface by the first groove 14 and the second groove 15 as shown in FIG. The continuous groove constitutes a first continuous groove and a second continuous groove extending in the longitudinal direction and the width direction over the entire floor heating construction area. In FIGS. 9 and 11, three circuits of hot water piping P are arranged along the first and second continuous grooves, and in FIG. 10, four circuits of hot water piping P are arranged along the first and second continuous grooves. Set up. The hot water pipe P forms the folded portion B in the second continuous groove, and extends in the longitudinal direction of the floor heating panel 1 along the first continuous groove. Each hot water pipe P is shown in FIG.

The first pipe 3 and the second pipe 4 are preferably made of elastically or elastically deformable rubber pipes, elastomer pipes or synthetic resin pipes, and are interconnected by a substrate or base sheet made of the same material. Suitably, the said board | substrate is equipped with the bottom face which can be adhere | attached on the bottom wall of a 1st and 2nd continuous groove. More preferably, the first pipe 3
The second pipe 4 is made of an integral molded pipe of rubber, elastomer or synthetic resin containing or containing synthetic fibers or short fibers of natural fibers.

The pipe 3 is connected to a hot water supply header (not shown),
The hot water supply header is connected to a hot water outgoing pipe (not shown). On the other hand, the second pipe 4 of each pipe system P taken out or drawn out from the floor heating panel 1 at the take-out portion E1 of each hot water pipe P is connected to a hot water return header (not shown), and the hot water return header is It is connected to a hot water return pipe (not shown). In addition, the first pipe 3 of each pipe system P taken out or drawn out from the floor heating panel 1 at the take-out portion E2 of each hot water pipe P is connected to the hot water reflux header, while the take-out portion of each hot water pipe P is taken out. The second pipe 4 of each pipe system P taken out or pulled out from the floor heating panel 1 at E2 is connected to the hot water supply header (not shown). Each pipe P is not limited to a pair of pipes, and as each pipe P, one pipe or pipe line, or, for example, about 4 to 8 rubber pipes or the like is mutually connected on the substrate or the base sheet. An integrally formed collecting pipe or pipe line assembly formed by connection may be adopted. This kind of flexible conduit assembly can be appropriately installed not only in the pipe grooves of the first and second continuous grooves of the floor heating panel 1 formed in a predetermined pattern, but also in the bending member. Alternatively, the pipe construction can be completed without using an elbow pipe or the like, which is extremely advantageous in simplifying and shortening the construction process and the construction period. Moreover, the pipe P having such a structure
According to the above, since it is possible to easily construct a continuous pipe route in which the seam of pipes, the connecting portion or the joint is substantially completely omitted over the entire floor heating region, in the entire floor heating region,
Not only is it desirable for simplifying the piping construction process or shortening the construction period, but it is possible to reliably prevent leakage or leakage of the heat medium liquid (hot water) from the joints of the pipes, the connection part or the joint, etc. It is extremely advantageous in practical use.

FIG. 3 is a perspective view and a partially enlarged cross-sectional view showing a pipeline assembly used in the floor heating apparatus shown in FIG. In this embodiment,
A floor heating system is a double floor that forms an underfloor wiring area such as electric wiring, power supply wiring, information / communication wiring, control wiring, OA equipment wiring, LAN wiring, various wiring joints, or various wiring branch / connection boxes. It is arranged in connection with the so-called free access floor, OA floor or office floor of the structure. This type of double-floor structure is a so-called office building or the like due to the recent office automation of office buildings and the like, the spread of various PCs (personal computers), or the sophistication of centralized management systems. Along with the intelligentization, it has been particularly emphasized in various buildings including general office buildings, research facilities, and commercial buildings. In addition, this type of double floor structure cuts off noise transmission between the upper floor and the lower floor,
Alternatively, in combination with the function of adjusting the top surface unevenness of the floor base S such as concrete slab or earthen concrete, the demand has increased particularly in recent years.

In such a double floor structure, the floor finishing material or the floor substratum F is a floor slab S such as a concrete slab, earthen concrete, deck plate and lightweight concrete, a wooden floor substratum, or a wooden floor slab. The wiring space or the wiring region of the electric equipment or the like is defined between the floor material F and the floor base S by lifting the wiring board to a predetermined height. As illustrated in FIG. 12, as a double floor structure, for example, a floor material F is placed on a pillar or a molding base C1 arranged at a predetermined position on the floor base S, which is a relatively simple construction type. Double floor structure (Fig. 12
(A)), a double-floor structure of a type in which a floor material F is placed on support legs (stands) or columns C3 aligned on the floor base S at predetermined intervals (Fig. 12 ( B)), or a double floor structure of a type in which hanging legs C4 integrally formed or arranged on the lower surface of the floor material F in advance are arranged at predetermined positions on the floor base S (see FIG. 12 (C)). )) And other various types are known. In this type of double floor structure, the floor material F
Is a so-called floor panel having a predetermined size and a predetermined shape, and the indoor-side floor surface composed of a large number of floor panels has a configuration capable of locally and individually removing the floor panel at an arbitrary position. Therefore, facility components (wiring, etc.) in the underfloor wiring area can be easily inspected / repaired from inside the room for maintenance and management of building facilities.

In the double-floor floor structure shown in FIG. 12 (A), the columns C1 are interconnected via strip-shaped connecting members C2 arranged in a grid, and the connecting members C2 are the floor bases S.
It is arranged on the upper surface of. In addition, FIG.
A protrusion having a relatively small diameter is formed on the top of each of the columns C1 and C3 shown in (B), while each floor material F standardized to a predetermined size and a predetermined shape is engaged with the protrusion. A circular opening is formed at a predetermined position. An underfloor facility space 50 having a predetermined height is defined under the floor by each type of double floor structure. Various electric / control / communication wirings L such as an electric equipment system, a communication system, and / or a control system are arranged in the underfloor equipment space 50, and a conduit assembly 51 that constitutes floor heating equipment piping is provided.
Are arranged in the underfloor equipment space 50.

FIG. 13 is a perspective view of the conduit assembly showing the structure of the conduit assembly 51 shown in FIG. As shown in FIG. 13A, the conduit assembly 51 interconnects the conduits 3 and 4 and the conduits 3 and 4 which are alternately arranged at a predetermined interval in the width direction on a common plane. It is formed of a long sheet-shaped molded product including the substrate 52. The tubular body 2 and the substrate 52 that form the pipelines 3 and 4 are made of an elastic material having elasticity that can be relatively easily elastically deformed, and the tubular body 2 and the substrate 52 are formed by a resin molding process such as an extrusion molding method. It is integrally molded. In this example, the conduit assembly 51 is made of a rubber material such as synthetic rubber, a synthetic resin, or an integrally molded product using a synthetic rubber and a mixed material of synthetic resins as a base material. Preferably, the conduit assembly 51
Is a long sheet-shaped integrally molded product that is made by continuously extruding a hybrid polymer elastomer whose main material or main material is special rubber mixed with synthetic fiber or natural fiber short fiber reinforcement by an injection molding machine. Therefore, a so-called rubber roll R that can be transported and carried in the field in a wound form is configured.

FIG. 14 is a partial vertical cross-sectional view of the underfloor heating equipment showing a schematic structure of a floor structure including the underfloor equipment space 50 having the above-described structure and a structure of a pipe line assembly 51 arranged in the underfloor equipment space 50. is there. In the construction, the conduit assembly 51 is unrolled from the rubber roll R and laid on the floor base S.
If desired, a heat insulating plate or a heat insulating material T such as a glass wool molded plate, a hard urethane resin molded plate, and Torrey Pef (product of Toray Industries, Inc.) is laid on the floor base S, and the conduit assembly 51 is provided.
Is laid on the heat insulating material T. If desired, a self-leveling material (SL material) is cast and spread on the floor base S, and after adjusting the unevenness or the ground by the self-leveling material, the pillar C is placed on a horizontal surface leveled by the self-leveling material.
1, C3, C4, the heat insulating material T, and the conduit assembly 51 may be installed or laid.

As shown in FIGS. 14A and 14B, the conduit assembly 51 is placed on the heat insulating material T via a predetermined adhesive material or an adhesive, for example, a cationic adhesive, and the substrate The back surface of 52 is bonded to the top surface of the heat insulating material T. Pipe line assembly 51
The piping path can be set relatively freely in the region between the columns C1, C3, and C4 due to the elastic deformation of the conduit assembly 51. Further, the wiring L is arranged, for example, in an inter-pillar region different from the inter-strut region in which the pipe line assembly 51 is piped, whereby the arrangement L of the pipe L and the pipe line aggregate 51 is clearly divided. At the same time, the wiring L and the conduit assembly 51 are separated from each other by at least a predetermined distance.

As a modified example, as shown in FIG.
The wiring L may be arranged between the heat insulating material T and the floor base S, and the wiring L and the conduit assembly 51 may be insulated by the heat insulating material T.
Further, as a construction step, the positions of the pillars C1, C3, C4 are previously marked on the floor base S, and the heat insulating material T and the conduit assembly 51 are laid and fixed at a position or a route where the pillar position can be avoided. After that, a series of steps for arranging and fixing the double floor structure on the floor base S (steps of the pipe preceding system), or the double floor structure is at least partially constructed on the floor base S. After that, a series of steps (a step of a pillar-preceding method) for appropriately laying and fixing the heat insulating material T and the conduit assembly 51 in the inter-pillar region between the pillars C1, C3, and C4 are performed at the construction site and the construction period. According to the above, it can be appropriately and selectively adopted. Alternatively, the double floor structure and the duct assembly 51 may be constructed after the self-leveling material has been previously cast on the concrete slab and the floor base S has been subjected to the non-uniformity adjustment or the level adjustment. Further, the construction of the heat insulating material T may be omitted, and the conduit assembly 51 may be laid directly on the floor base S. If desired
The self-leveling material is further cast on the upper surface of the conduit assembly 51 laid on the floor base S or the heat insulating material T to form the conduit assembly 5
1 may be covered with a self-leveling material, or the conduit assembly 51 may be embedded in the self-leveling material to further improve the construction efficiency and floor heating efficiency by the conduit protection function and heat storage effect of the self-leveling material. It is possible. In addition,
In contrast to the so-called floor panel that constitutes the floor material F, a surface layer decorative material E such as a PVC sheet or P tile that constitutes the indoor side surface.
(FIG. 14) may be further laminated.

FIGS. 15 and 16 are schematic cross-sectional views illustrating the plane structure of the underfloor facility space 50 formed by laying the double floor structure and the conduit assembly 51. 15 and 1
