Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of installing a floor heating device of a hot water piping system. 2. Description of the Related Art As a floor heating device, a floor heating device of a hot water piping system in which a hot water pipe capable of circulating hot water heated by a heat source is embedded in a floor is known. Also, as another type of floor heating device, an electric heater type floor heating device in which a planar heating element made of an electric heating heater capable of supplying electricity is embedded in the floor is known. As a hot water piping type floor heating device,
Generally, a pipe such as a copper pipe is used, and the pipe is laid on a concrete floor foundation, for example. Concrete or mortar is cast or ironed so as to cover the pipe, and the hot water pipe is covered with concrete or mortar. As this kind of floor heating piping,
As disclosed in Japanese Patent Application Laid-Open No. 5-123994, a floor heating device is known which has a configuration in which an elastic pipe made of a material such as rubber is laid on a concrete floor foundation and then a thick concrete layer is cast on the pipe. . Further, a floor heating device in which a planar heating element is arranged on a floor base is disclosed in Jpn.
No. 1828 and Japanese Utility Model Application No. 52-90253. The sheet heating element is composed of, for example, a sheet heating element made of a synthetic polymer compound containing carbon powder, or a plate in which an insulating base is coated with a carbon resistance heating paint. The sheet heating element is covered with a gypsum-based mortar layer or a flooring material having self-level performance. This type of floor heater of the electric heater type has problems regarding durability, centralized control, maintenance management, and the like, and is difficult to adopt in a medium- or large-scale building in which power consumption is regulated or limited. Therefore, it is difficult to use such a floor heating device with a planar heating element as a permanent floor heating device for general buildings. [0003] On the other hand, in a conventional hot water piping type floor heating apparatus using metal piping or the like, the piping is covered with a relatively thick concrete layer or mortar layer. Such a concrete layer or the like exhibits a sufficient impact strength of the floor surface, and expresses desired durability or strength of the floor surface so that the floor load or the impact acting on the floor surface does not affect the piping. In particular, the concrete layer or the mortar layer covering the hot water piping prevents the concrete or mortar itself from drying and shrinking cracks, and also avoids the generation of cracks due to the burial of the piping, so that the concrete portion or mortar immediately above the buried piping can be used. Since it is necessary to secure the coating thickness of the mortar part at least about 3 to 4 cm, the thickness of the entire concrete layer or the entire mortar layer must be designed to be at least about 50 mm to 100 mm. However, in buildings, especially middle- and high-rise buildings that are subject to structural regulations or height regulations, the cross-sectional dimensions of the entire floor structure are designed to be as small as possible to reduce dead load or fixed load on the floor and to make effective use Since it is necessary to increase the possible floor height, the conventional floor heating device using the hot water piping system has a problem in adopting it for designing a medium-sized or large-scale building. [0004] In addition, the hot water pipe in the concrete layer or mortar layer designed to be thick as described above is located at a position where the embedding depth from the floor surface is deep. Therefore, it takes a lot of time to raise the temperature of the floor surface facing the room. As a result, the so-called heating rise time is slow, and after the heating starts, the room air reaches the desired heating target temperature. A long initial heating time was required. Furthermore, in the floor heating device having the configuration in which the elastic pipe is covered with concrete as described above, the concrete shrinks due to drying shrinkage.
Phenomena, repeated thermal expansion and contraction of elastic piping, and thermal expansion and contraction of floor material or floor base due to temperature change, cement and aggregate (coarse or fine aggregate) in the outer surface of the pipe and concrete ), Cracks or breaks occurred in the elastic piping due to high adhesive strength of concrete, etc., and water leakage accidents occurred frequently. In addition, the conventional method of constructing a hot water pipe for floor heating requires a complicated operation of bending the pipe in advance and binding and fixing the pipe to another buried object such as a reinforcing bar or a wire mesh. The number of construction steps was large, and the construction period of the floor heating device was prolonged. [0005] The above problems are the facts that the present inventor has learned at the time of developing the present invention. The present invention has been made in view of such a point, and an object of the present invention is to provide a method of constructing a hot water piping type floor heating device capable of solving the above-mentioned problems in a hot water piping type floor heating device. Is to do. [0006] In order to achieve the above object, the present invention lays a plurality of elastic hot water pipes (2) on the upper surface of a flat floor substrate (5). And flowing the self-leveling material (3) from above the hot water pipe (2) and embedding the hot water pipe (2) in the self-leveling material (3). provide. According to an embodiment of the present invention, a reinforcing material (1) is provided above the hot water pipe (2).
Is laid, and the reinforcing material (1) is the self-leveling material.
It will be buried in (3). In another embodiment of the present invention, a heat insulating paper (4) is arranged below the hot water pipe (2), or a waterproof paper (4) is arranged below the hot water pipe (2). According to the present invention, a thin hot water piping type floor heating device comprising a hot water piping (2) and a self-leveling material (3) is provided on a floor substrate (5) which has been ground with concrete or the like. It is constructed in. According to the above configuration of the present invention, the elastic pipe (2) is laid along the upper surface of the floor substrate (5). In general, the upper surface of the floor substrate (5), for example, the upper surface of a concrete slab, has a large amount of unevenness over a wide area.However, the elastic pipe (2) is not suitable for conventional metal piping that requires bending and pipe binding work. Alternatively, it can be laid to fit in the cross section of the thin self-leveling material (3) due to self-displacement or self-deformation. Therefore, the hot water pipe (2) could be buried in the self-leveling material (3) that could be cast to a thin thickness (at most about 20 mm). Thus, according to the present invention, an extremely thin (approximately 20 mm) hot-water piping type floor heating device which could not be realized conventionally has been realized. Moreover, when the hot water pipe (2) for floor heating is buried in the self-leveling material (3) in this manner, no cracks (cracks) occur in the self-leveling material (3), and the elastic pipe is cracked or broken. It has been confirmed by the present inventors that no water leakage occurs due to the above, and that sufficient floor strength and durability can be ensured. In addition, the floor heating device having the above configuration can raise the temperature of the floor surface in a short time, and as a result, the initial heating time at the time of starting heating can be significantly reduced. Further, since the thickness of the floor heating device is extremely thin, and a relatively rapid temperature change occurs in a short time at the time of starting heating, the self-leveling material (3)
Many cracks on the surface of the pipe or hot water pipe
Although it was naturally expected or predicted that (2) would be cracked or damaged, it was found that cracks were not likely to actually occur, and no cracking or damage occurred to the hot water pipe (2). This is because the self-leveling material (3) survived unexpectedly repeated temperature changes and sudden temperature rises, and the characteristics of the self-leveling material (3), which is essentially a material that can be cast to a small thickness, are used. In addition, the extremely thin pipe coating thickness was made possible.Moreover, when a crack occurred in the self-leveling material (3) in the floor heating device, the elastic hot water pipe (2) was locally displaced or expanded and contracted. This is considered to be due to the fact that it can follow the occurrence of cracks. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view of a hot water floor heating apparatus according to the present invention. Referring to the drawings, an embodiment of the present invention will be described.
explain. In the drawings, reference numeral 1 indicates a reinforcing material such as a net or a net, reference numeral 2 indicates a hot water heater or a pipe, and reference numeral 3 indicates a self-leveling material. In addition, reference numeral 4 indicates heat insulating paper or waterproof paper, reference numeral 5 indicates a foundation concrete constituting a floor foundation, and reference numeral 6 indicates a reinforcing bar or a wire mesh in the foundation concrete 5. . An elastic hot water pipe 2 made of rubber or the like
Is laid, and pressure is applied to the inside of the hot water pipe 2 if desired. The self-leveling material is poured onto the foundation concrete 5 from above the hot water pipe 2, and the hot water pipe 2 is embedded in the self-leveling material 3 and solidified by the self-leveling material 3. If desired, a reinforcing material 1 such as a net or a net is embedded in the self-leveling material 3, and a heat insulating paper or waterproof paper 4 is interposed between the self-leveling material 3 and the foundation concrete 5. [0010] The inventor of the present invention has succeeded in constructing a floor heating apparatus which is powerful and has a rapid rise in temperature by using the floor heating apparatus having such a configuration. Moreover, with such a configuration, it is possible to construct an extremely thin (at most about 2 cm thick) hot-water piping-type floor heating apparatus on the floor base surface formed by the basic concrete 5. As described above, according to the above-described structure of the present invention, an extremely thin floor heating device can be formed on a floor base or a floor by burying a hot water pipe for floor heating in a thin self-leveling material. It can be installed on a floor slab, and as a result, dead load or fixed load on the floor can be significantly reduced and effectively used as compared with a conventional hot water piping type floor heating device requiring thick concrete or mortar coating. It became possible to increase the floor height. Furthermore, when the elastic pipe is buried in the self-leveling material, the hot water pipe does not crack or break, so that the water leak accident caused by the crack or the break of the hot water pipe can be completely avoided, and It was confirmed that the floor heating system using hot water pipes buried in self-leveling material achieves efficient floor heating that can start heating very early due to good heat conduction performance. In addition, according to the floor heating device of the present invention, the floor changes its temperature in a short time at the time of starting heating or the like, and therefore, despite the repetitive thermal expansion / contraction of the self-leveling material, the floor of the hot water pipe is not affected. It was found that no cracking or damage, no cracking of the self-leveling material, and the like occurred. Further, according to the construction method having the above-described configuration, it is possible to omit the bending work of the pipe by a tool and the work of fixing and tying the pipe to the reinforcing steel bar or the wire mesh as in the floor heating apparatus using a copper pipe or the like. The floor heating system can be substantially completed by a simple or simple process of laying pipes and flowing self-leveling material, greatly reducing the floor heating system construction period and significantly reducing the number of construction steps. Could be reduced. In addition, by applying the above-mentioned construction method of the present invention to construction such as remodeling and renovation, it is possible to install a floor heating device of a hot water piping system in a part of a building where a floor heating device could not be installed by the conventional method. Became possible.
Furthermore, in the present invention, since the elastic pipe is buried, not only the construction can be simplified, but also the elastic pipe can follow a change such as a crack of the self-leveling material to some extent.
Cracks and breaks in piping can be reliably avoided.
