Sectional view, FIG. 24 is a process chart showing a comparative example to show the benefits of floor structure of the hot water floor heating system of the present embodiment.

That is, the hot water floor heating system 10 of FIG. 1 is disclosed as being applied to an office, and the hot water floor heating system 10 of FIG. 2 is as being applied to a general house. As shown in FIG. 1, the hot water type floor heating system 10 prepares a plurality of floor panels 14 having the pipes 12 built therein, and connects the floor panels 14 to the floor panels 14 connected to each other. It is designed to be laid on the control panel 16 which is a base material. Then, by introducing hot water supplied from the boiler 18 into the pipe 12, the floor panel 14 is heated to perform floor heating. A flooring material 20 is laid on the upper surface of the floor panel 14.

As shown in FIGS. 3A to 3F, a plurality of types and standardized floor panels 14 are prepared in advance corresponding to each aspect. That is, the floor panel 14 of FIG. 1A is a basic shape, and is formed in a rectangular shape with the short side x and the long side y, and the built-in pipe 12 is arranged parallel to the long side y. Both end portions 12a, 12a are projected from both end surfaces 14a, 14b in the long side y direction. In the floor panel 14 of FIG. 2B, the pipe 12 is turned in a U shape inside the floor panel 14, and both ends 12a 1 and 12a of the pipe 12 are projected from one end face 14a in the long side y direction. . In the floor panel 14 of FIG. 3C, the short side is formed to be smaller than x, and both ends 12a and 12a project from both ends 14a and 14b. One U-shaped pipe 12 from which 12a and 12a are projected is incorporated. The floor panel 14 of FIG. 3D has a short side x remarkably shorter than the floor panel 14 of FIG. 1A, and one end 12a, 12a protrudes from each end 14a, 14b. Is built in. Further, FIGS. 6 (e) and 6 (f) are obtained by shortening the long side y 1 of the floor panel 14 in FIGS. 4 (a) and 4 (b) to about half.

In this embodiment, the pipe 12 has a diameter of 15 mm (a diameter of about 8 mm is conventionally used). Therefore, as the diameter of the pipe 12 is increased, the thickness of the floor surface becomes about 35 mm (conventionally about 12 mm).

When laying the floor panel 14, the ends 12a of the pipes 12 protruding from the end surfaces 14a and 14b of the floor panels 14 are connected as shown in FIG. 9 or 10, for example. That is, in the case shown in FIG. 9, the opposite end portions 12a, 12a protruding from the adjacent floor panel 14 are connected to each other, and the straight joint pipe 22 is provided on the outer periphery of each end portion 12a, 12a. Are designed to fit together. On the other hand, in the case shown in FIG. 10, the adjacent end portions 12a, 12a protruding from one floor panel 14 are connected to each other, and the respective end portions 12a, 12a are L-shaped joints. The pipe 24 and the straight joint pipe 22 are connected in combination.

By the way, when the floor panel 14 is laid with the pipes 12 connected, in order to secure the connection portion between the end portions 12a, 12a, the floor panels 14, 14 adjacent to each other are secured. A gap portion δ is formed in the gap. Further, since the floor panel 14 is standardized to have a constant shape as described above, when the floor panel 14 is laid along the floor shape of the room R, the floor panel 14 and the peripheral portion of the floor panel 14 laid are inevitable. A room S is formed between the room R and a corner.

Here, in this embodiment, the gap portion δ is filled with the joint panel 26, and the space S is filled with the space panel 28. As shown in FIGS. 4 to 7, the joint panel 26 is formed with a width w equal to the gap portion δ, and a pipe insertion portion 30 into which the connecting portion of the pipe 12 is fitted is formed.

That is, in the joint panel 26 shown in FIG. 4, the pipe insertion portion 30 corresponds to the connection portion shown in FIG. 9, and a plurality of pipe insertion portions 30 are formed in parallel in the width w direction. . Further, the joint panel 26 shown in FIG. 5 corresponds to the connecting portion shown in FIG. 10, and the pipe insertion portion 30 is formed in an L shape or a U shape. Further, the joint panel 26 shown in FIG. 6 is formed on the assumption that the pipe 12 is arranged in parallel along the end surface 14a of the floor panel 14, and the pipe insertion portion 30 has a width w. It is formed in the direction orthogonal to each other. Furthermore, the joint panel 26 shown in FIG. 7 also serves as all the pipe insertion portions 30 shown in FIGS. 4 to 6, and the pipe insertion portion 30 is formed vertically and horizontally. Therefore, by using the joint panel 26 shown in FIG. 7, it is possible to cover all the joint panels 14 shown in FIGS. 4 to 6.

On the other hand, a pipe 18 a is provided for supplying hot water from the boiler 18 to the pipe 12 of the floor panel 14 or for returning the hot water after passing through the pipe 12 to the boiler 18. 18a is arranged in the space S. The space panel 28 may include a pipe insertion portion 32 through which the pipe 18a is inserted and a space panel 28 in which the pipe 18a is not disposed and the pipe insertion portion 32 is not required. Therefore, as shown by the alternate long and short dash line in FIG. 8, the room panel 28 of this embodiment has two pipe insertion portions 32 oriented in the length direction on one side in the width direction and the other side in the width direction. One pipe insertion part 32 is formed. The room panel 28 is cut and used according to the size of the room S.

The joint panel 26 is formed with a cross-sectional structure as shown in FIGS. 11 to 22, and has a heat conductive member (shown by A in the drawing) and a heat insulating material having plastic properties (shown by B in the drawing). ) And a heat insulating material having elastic properties (indicated by C in the figure) are appropriately combined to form a dry type. For example, the joint panel 26 shown in FIGS. 11 to 18, 20, and 21 includes a lower layer member 34 and an upper layer member 36, and the pipe insertion portion 30 is formed between these members 34, 36. The pipe insertion portion 30 is formed by recessing the joint surfaces of both the lower layer member 34 and the upper layer member 36 (FIGS. 11, 12, 14, and 20), and the lower layer member 34 and the upper layer member 36. The intermediate layer 38 which is interposed therebetween is divided into spaces to be formed in the separated space portions (FIGS. 13, 16 and 17), and only one of the lower layer member 34 and the upper layer member 36 is provided with a concave joint surface. Some of them are formed (FIG. 15, FIG. 18, FIG. 21).

In FIG. 11 and FIG. 14, the pipe insertion portion 30 is formed with a semi-circular concave portion along the outer shape of the pipe 12 on both the lower layer member 34 and the upper layer member 36. The recess on the lower layer member 34 side is formed to have a rectangular cross section. Further, the pipe insertion portion 30 may be penetrated through the lower surface as shown in FIGS. 19 to 22.

By the way, in the joint panel 26, the lower layer member 34 is mainly formed of the heat insulating material having the plastic property of B or the heat insulating material having the elastic property of C, but one upper layer member 36 Is formed by a heat conductive member of A or a heat insulating material having plastic properties of B. When the upper layer member 36 is formed of a heat insulating material having the plastic property of B, the heat conductive member layer 40 is formed on the surface of the upper layer member 36 (FIGS. 11, 12, 15 and 15). (See FIGS. 16 and 20). Further, as shown in FIG. 19, a heat insulating material mainly having the plastic property of B can be formed, and a heat conductive material layer 40 can be provided on the upper surface thereof. Further, as shown in FIG. It can also be formed of a heat conductive member. Here, the material of the intermediate layer 38 may be either the heat insulating material having the plastic property of B or the heat insulating material having the elastic property of C.

The heat conductive member A can be formed as a molded product made of synthetic resin or metal, and the heat insulating material B having the plastic property is made of hard polystyrene foam or polyethylene foam. To be Further, as the heat insulating material C having elastic properties, a restorative material such as urethane is used.

By the way, the sectional structure of the joint panel 26 is shown in FIGS. 11 to 22, but the room panel 28 is also formed in the same structure as the joint panel 26.

On the other hand, as shown in FIG. 23, the corners of the joint panel 26 and the room panel 28 are fixed to the control panel 16 via the screws 42. By providing the collar 44 of a certain length at the screw insertion portion, when the screw 42 is tightened, the joint panel 26 and the margin panel 28 are inclined due to the difference in the tightening force, so that the space between them is adjacent. It is possible to prevent a step from occurring.

In the hot water type floor heating system 10 of the present embodiment having the above configuration, the gap portion δ and the room portion S that remain when the floor panel 14 is laid are the dry joint panel 26 and Filled by room panel 28. Therefore, unlike the conventional case where a wet filler such as mortar or self-leveling material is used to fill the gap portion δ and the space portion S, a curing period and a surface finish after the construction are not required. Therefore, it is possible to reduce the number of workers, the construction period, and the man-hours.

For example, FIG. 24 shows a process chart in the case where the conventional wet filler is used. First, it takes 3 days to lay the board and pipes, and on the first day, there are 3 workers and 2 workers. Two are engaged on the day and three on the third. The pouring (filling work) of the self-leveling material is completed in one day by three workers, but on the next day, two workers will perform surface finishing with sanders. Finally, the finishing work is carried out over two days, and the finishing work on the floor surface and the room which is soiled by the self-leveling material is carried out, which requires one person on the first day and two persons on the second day. A worker is required. Here, in the hot water type floor heating system 10 of the present embodiment, even though the above steps 1 and 2 require substantially the same number of people for laying the floor panel 14 and for mounting the joint panel 26 and the room panel 28, It eliminates the need for surface finishing with a sander, and allows one operator to finish the work in one day.

Therefore, in the past, the total number of persons required was 13 in 6 days from 9/21 to 10/8 including the curing period of the self-leveling material. It will be 1 day, and the total construction period will be 4 days, and the total number of people will be 9 people, and it will be possible to achieve a significant reduction in construction period and labor saving (reduction of work personnel, reduction of man-hours). .

On the other hand, in the case where the diameter of the pipe 12 is 8 mm, which is generally adopted in the past, and the wall thickness of the floor is relatively thin, about 12 mm, the pipe 1 is used as in the present embodiment. When the diameter of 2 is increased to 15 mm, the thickness of the floor surface (about 35 mm) is further increased. Therefore, if self-leveling material is used, the number of filling days and workers will be further increased. . In the present embodiment, the amount of hot water introduced can be significantly increased by increasing the diameter of the pipe 12, and the heat capacity of the floor heating is increased by that amount, enabling immediate and instantaneous heating and improving the performance of the heating system. In addition, the work man-hours and the number of days are not affected by the increase in the pipe diameter, and the labor saving of the work can be achieved.

By the way, the joint panel 26 and the room panel 28 are configured by including a lower layer member 34 arranged below the pipe 12 and an upper layer member 36 arranged above the pipe 12, and Since the pipe insertion portions 30 and 32 can be formed between the lower layer member 34 and the upper layer member 36, the pipe 12 of the floor panel 14 is connected in a state where the lower layer member 34 is arranged in advance, and then the upper layer member is connected. 36 can be disposed, and the connecting portion and the disposing portion of the pipe 12 can be easily accommodated in the joint panel 26 and the room panel 28.

Further, by forming the lower layer member 34 and / or the upper layer member 36 with the heat insulating material B or C, the pipe 12 into which hot water is introduced is kept warm so that the amount of heat escapes under the floor. It can be prevented and the heat loss can be significantly reduced. Here, since the C member is used as the heat insulating material of the lower layer member 34 and / or the upper layer member 36 so as to have elastic properties, cushioning property can be secured on the floor surface, and at the same time, the lower layer member 34 and By providing the above-mentioned B member as the heat insulating material of the upper layer member 36 and providing it with a plastic property, when the joint panel 26 and the room panel 28 are laid, the laying surface, that is, the uneven portion such as the connecting portion of the control panel 16 is It can be deformed accordingly and the installed condition can be stabilized.

Further, since the heat conductive member layer 40 is provided on the surface of the upper layer member 36, the temperature can be made uniform over the entire surfaces of the joint panel 26 and the room panel 28. Further, since the lower layer member 34 and the upper layer member 36 are integrally formed of the heat conductive member A and the pipe insertion portions 30 and 32 are formed in the middle layer portion thereof, the temperature of the pipe 12 can be transferred to the surface more quickly. In addition, the instantaneous heating effect at the start of heating can be further improved.

Furthermore, the pipe insertion portions 30 and 32 are formed by recessing the contact surfaces of the lower layer member 34 and the upper layer member 36, respectively, so that the pipe insertion portions 30 and 32 are easily formed. be able to. In addition, the intermediate layer 38 is interposed between the lower layer member 34 and the upper layer member 36, and the intermediate layer 38 is divided to form the pipe insertion portions 30 and 32 in the separated space portions. , 32 can be further simplified.

By the way, furniture such as furniture and appliances are arranged in the room R, and it is necessary to avoid heating these appliances by heat from the floor surface as much as possible. By providing a non-heat conductive member layer (not shown) on the surfaces of the panel 26 and the room panel 28 in place of the heat conductive member layer, it is possible to prevent the radiation heat from the pipe 12 from affecting the equipment. .
