Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating facility construction method and floor heating structure in a factory, an office, a general house or the like, and more particularly to a floor heating facility construction method and floor heating structure using a heat storage material. It is a thing.

[0002]

2. Description of the Related Art In factories and offices in cold regions, there are more and more cases in which floor heating equipment having heating elements such as electric heaters and hot water pipes is installed under the floor in anticipation of a heating effect from the feet. There is. In recent years, heat storage type floor heating equipment that uses a heat storage material in combination with the above heating element has become the mainstream because of advantages such as low maintenance costs.

Floor heating equipment is usually placed under the floor when building or remodeling a building, and is usually buried under the floor by pouring concrete on it or fitting a floor material. Further, generally, a floor heating facility is not arranged at a site where a mechanical device or the like is installed in consideration of a heat effect of floor heating.

[0004]

However, in the case of the buried floor heating equipment as described above, it is practically impossible to move the floor heating equipment when attempting to relocate the mechanical device. There is an inconvenience that the rearrangement itself cannot be executed. If the mechanical device is forcibly moved, the mechanical device is directly heated and adversely affected. On the other hand, when installing a floor heating facility on an existing floor, in many cases, a method has been adopted in which a space capable of accommodating the floor heating facility is formed by excavating the floor surface, and surface finishing is performed again. There was also a problem that the construction was extremely troublesome. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems, and provide a floor heating facility construction method and a floor heating structure that are movable and can be easily installed on an existing floor.

[0005]

A method of constructing a floor heating facility according to the present invention is a pattern in which an existing floor is divided into a floor heating construction portion and a non-construction portion, and a floor heating construction portion intends a support member on the existing floor. And the floor heating device is installed, and then the surface floor material is fitted onto the support member.

Further, the floor heating structure of the present invention includes a floor heating device arranged at a required portion on an existing floor, a surface floor material covering the floor heating device, and a surface floor material supporting and supporting the surface floor material. The support member serves as a fitting frame.

In the above structure, the floor heating device is a heat storage type floor heating device including a heat storage material and an electric heater.
It is desirable because it is easier to lay and remove than floor heating systems such as hot water pipes. Furthermore, if the floor heating device is composed of a heat insulating material arranged on an existing floor, a first heat storage material unit sequentially provided thereon, a planar heating element, and a second heat storage material unit, Efficient heat storage to the heat storage material and good heat dissipation characteristics to the surface floor material can be obtained, and since each component is unitized, there are advantages such as easier installation and removal.

As the heat storage material unit, it is possible to use a flat plate-like material in which a latent heat storage material is covered with a metal laminate film to prevent deterioration of the heat storage material due to contact with air or water, and to provide a bag body. It is desirable because the heat storage material can be enclosed in the box to improve the handleability during installation and removal.
In addition, when the heat storage material is sealed, it is preferable to vacuum the inside of the bag and then seal the bag because the heat transfer property is improved.

As the surface floor material, various materials can be used, but a preferable material is a metal floor material having good heat conductivity such as aluminum and a surface finishing material. The heat from the device can be efficiently transferred to the floor surface.

[0010]

According to the present invention, the surface floor material is disposed on the existing floor via the support member to form a double floor structure (so-called free access floor) in which a space is secured between the support member and the surface floor material. The floor heating device is arranged in the space. Therefore, even if it is necessary to partially install the floor heating equipment on the existing floor or move the floor heating equipment according to the relocation of the mechanical device, the support member is erected and the surface floor material is assembled by fitting, Alternatively, it can be easily dealt with by disassembling these.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. 1 to 3 are views sequentially showing a method of constructing a floor heating facility of the present invention. First, as shown in FIG. 1, an existing floor 1 in a room where floor heating equipment is to be constructed is divided into a floor heating construction section A and a floor heating non-construction section B.
In the illustrated example, a portion where the mechanical device M is present is a non-construction portion B, and the other portion is a construction portion A. The determination of this section is arbitrary, and may be appropriately set according to the layout of mechanical equipment or the like in a factory or the like, and the layout of office automation equipment or a desk or the like in an office or the like.

Next, as shown in FIG. 2, the supporting member 5 is erected on the existing floor 1 in an intended pattern. The support member 5 may be erected in the same manner as when constructing a free access floor. Although the present embodiment shows the support member 5 including the existing floor 1, the support portion 51 fixed by the anchor bolts and the like, and the wide receiving portion 52 attached to the upper surface thereof, various other free access floors are provided. The configuration of can be adopted. A surface floor material, which will be described later, is fitted on the receiving portion 52 of each support member 5 so as to be bridged. Note that a frame member for supporting the surface floor material may be bridged between the receiving portions 52.

After the support member 5 has been erected, a floor heating device is installed. The laying of the floor heating device starts with the laying of the heat insulating material 2 in the space partitioned by the supporting member 5. The heat insulating material 2 blocks heat directed toward the existing floor 1 and efficiently directs the heat toward the floor surface. For example, foamed polystyrene, foamed polyurethane, foamed polyethylene, or rigid foamed urethane is molded into a plate shape. What was done can be used.

A heating device is placed on the heat insulating material 2. In the present embodiment, an example of a heat storage type heating device including the electric heater 4 and the heat storage boards 31 and 32 is shown. In these, the first heat storage board 31 is placed directly on the heat insulating material 2, and the planar shape is placed thereon. The electric heater 4 and the second heat storage board 32 are sequentially placed and arranged. With such a configuration, the heat radiated by the electric heater 4, which is a heat source, is absorbed by the heat storage boards 31 and 32 located on both sides thereof, so that there is an advantage that the heat storage efficiency for the heat source is good.

Various floor heating devices other than the above may be used. For example, a heater wire meanderingly arranged on a heat insulating material, a heat medium circulating pipe installed, a heat storage material unit used in combination with these, and the like. From the viewpoints of economy and easiness of installation / removal, it is preferable to use the above-mentioned heat storage boards 31 and 32 and the planar electric heater 4.

As the heat storage boards 31 and 32, a bag made of a metal laminated film such as an aluminum-plastic film in which a latent heat storage material is vacuum-sealed can be preferably used. Various materials can be used as the heat storage material. For example, 100 parts by weight of paraffins and 5 to 30 parts by weight of hydrocarbon organic polymer as described in JP-A-4-85387 are used as mechanical means. The heat storage material obtained by mixing the above can be preferably used. The heat storage material is preferable because it has a shape-retaining property even during a phase change and is excellent in handleability. Further, it is preferable to vacuum-enclose the heat storage material at the time of encapsulation in the aluminum laminate film or the like, because the heat resistance can be improved without damaging the heat transfer property and the external damage resistance can be improved.

As the electric heater 4, various linear heaters or planar heaters can be used, but the heat storage boards 31, 32 are used.
A sheet heater is preferable in that heat can be uniformly transferred to the entire surface of the sheet. For example, a sheet formed by dispersing and blending conductive carbon or the like in rubber / plastic can be used.

After laying the floor heating device, the surface floor material is fitted onto the support member 5 as shown in FIG. In the present embodiment, for example, a metal floor material 6 obtained by processing a metal material having good thermal conductivity such as an aluminum plate into a rectangular flat plate shape that straddles the receiving portions 51 of the four support members 5, and the metal floor material 6 are An example is shown in which a surface flooring material is formed using a thin (about 2 mm) decorative surface finishing material 7 which is tightly fitted and stretched. This configuration is preferable because the heat generated from the heat storage boards 31 and 32 can be satisfactorily transferred to the floor surface.

When the floor heating equipment constructed as described above is to be removed, the surface finishing material 7 is peeled off, and the metal floor material 6 in the fitted state is removed, so that the heat insulating material 2, the heat storage boards 31, 32, and Since the electric heater 4 is simply in a laminated state, it can be easily removed, and when the room is to be relocated, the support member 5 is removed and repositioned in an intended pattern, and then the heat insulating material 2 and the heat storage are stored in the same procedure. Board 3
By laying 1, 32 and the electric heater 4, it is possible to cope with them easily.

[0020]

As described above, according to the floor heating equipment construction method and floor heating structure of the present invention, the floor heating equipment once laid is crushed like the conventional buried floor heating equipment. Since it can be relocated without having to do so, it is possible to easily re-install the floor heating equipment laid in the factory or the like according to the rearrangement of the mechanical device or the like.

Further, since this is an assembled floor heating system which adopts the concept of a so-called free access floor without concrete pouring, the floor heating system used at a certain place can be easily installed and removed. It has an advantage that it can be reused in other places, and also has an advantage that it can be easily dealt with when newly installing a floor heating facility on the floor surface of an existing building.
