DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a floor heating system and a floor heating structure in a factory, an office or a general house, and more particularly to a method of constructing a floor heating system using a heat storage material and a floor heating structure. Things.

[0002]

2. Description of the Related Art In factories and offices in cold regions, floor heating facilities in which a heating element such as an electric heater or a hot water pipe is provided under the floor are expected to increase the heating effect from the feet. I have. In recent years, a regenerative floor heating system using a heat storage material in combination with the above-described heating element has become mainstream because of its advantages such as low maintenance cost.

[0003] Floor heating equipment is usually placed under the floor when building or remodeling a building, and is usually buried under the floor by casting concrete on it or inserting flooring. Generally, floor heating equipment is not provided at a location where a mechanical device or the like is installed in consideration of the thermal effect of floor heating.

[0004]

However, in the case of the above-mentioned buried type floor heating equipment, when the rearrangement of the machinery and the like is to be performed, the movement of the floor heating equipment is substantially impossible. There is a disadvantage that the rearrangement itself cannot be executed. If the mechanical device is forcibly moved, there is a problem that the mechanical device is directly heated and adversely affected. On the other hand, when floor heating equipment is installed on the existing floor, in many cases, a means is provided to form a space in which the floor heating equipment can be stored by excavating the floor surface, for example, and performing surface finishing again. There was also a problem that construction took a lot of time. An object of the present invention is to solve such a problem and to 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]

According to the method of constructing a floor heating system of the present invention, an existing floor is divided into a floor heating construction section and a non-construction section, and the floor heating construction section is detachable on the existing floor. The support member is erected in the intended pattern and the heat storage material
A regenerative floor heating device comprising an electric heater is laid, and then a detachable fitting type metal floor material is fitted on the support member, and the metal floor material is covered with a surface finishing material .

Further, the floor heating structure of the present invention comprises a heat storage material comprising a heat storage material and an electric heater arranged at a required portion on an existing floor.
And wherein floor heating device, a removable covering the floor heating system
A fitting metal flooring and a surface finish covering the same,
A support for supporting the metal flooring material and serving as a fitting frame for the metal flooring material ;
And a support member that can be removed .

In the above configuration, the floor heating device is a regenerative floor heating device including a heat storage material and an electric heater.
It is desirable because it can be easily laid and removed as compared with a floor heating device such as a hot water pipe type. Furthermore, if the floor heating device is composed of a heat insulating material disposed on the existing floor, a first heat storage material unit sequentially provided thereon, a planar heating element, and a second heat storage material unit, There are advantages in that efficient heat storage in the heat storage material and good heat radiation characteristics to the surface floor material can be obtained, and since each component is unitized, installation / removal becomes easier.

As the above-mentioned heat storage material unit, it is preferable to use a plate-shaped one in which a latent heat storage material is wrapped with a metal laminated film, so that deterioration of the heat storage material due to contact with air or water can be prevented, and a bag body can be prevented. It is desirable in that the heat storage material can be enclosed in it to improve the ease of handling during laying and removal.
Further, when enclosing the heat storage material, it is preferable to seal the bag after evacuating the inside of the bag since heat transfer is improved.

Various types of surface flooring materials can be used, but a preferred material is a metal flooring material having good thermal conductivity, such as aluminum, and a surface finishing material. The heat from the device can be efficiently transmitted to the floor surface.

[0010]

According to the present invention, a surface flooring is disposed on an existing floor via a support member, and a double floor structure (a so-called free access floor) in which a space is secured between the support member and the surface flooring, The floor heating device is arranged in the space. Therefore, even if it is necessary to install floor heating equipment partially on the existing floor, or if it is necessary to relocate the floor heating equipment in accordance with the rearrangement of mechanical equipment, assembling by erecting the support member and fitting the surface floor material, Alternatively, it is possible to easily cope with the disassembly.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 to FIG. 3 are diagrams sequentially showing a construction method of 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 installed is divided into a floor heating installation part A and a floor heating non-installation part B.
In the illustrated example, the portion where the mechanical device M exists is referred to as a non-construction portion B, and the other portions are referred to as a construction portion A. The determination of this section is arbitrary, and may be appropriately set according to the layout of OA equipment, desks, and the like in a factory and the like, and in offices and the like.

Next, as shown in FIG. 2, a support 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 a free access floor is constructed. In the present embodiment, the support member 5 including the existing floor 1, the support portion 51 fixed by anchor bolts and the like, and the wide receiving portion 52 attached to the upper surface thereof is shown. Can be adopted. On the receiving portion 52 of each support member 5, a surface floor material described later is fitted so as to be bridged. Note that a frame member for supporting the surface flooring material may be bridged between the receiving portions 52.

When the support member 5 has been erected, a floor heating device is laid. The laying of the floor heating device starts with the laying of the heat insulating material 2 in the space partitioned by the support member 5 first. The heat insulating material 2 is used to block heat toward the existing floor 1 and efficiently direct the heat toward the floor surface. For example, foamed polystyrene, foamed polyurethane, foamed polyethylene, hard foamed urethane, or the like is formed into a plate shape. Can be used.

A heating device is placed on the heat insulating material 2. In the present embodiment, an example of a regenerative heating device including the electric heater 4 and the heat storage boards 31 and 32 is shown. In these examples, the first heat storage board 31 is placed directly on the heat insulating material 2 and the first heat storage board 31 is placed on the first heat storage board 31. The electric heater 4 and the second heat storage board 32 are sequentially placed. With such a configuration, the heat stored in the heat storage boards 31 and 32 located on both sides of the heat radiated by the electric heater 4 serving as the heat source absorbs the heat, so that there is an advantage that the heat storage efficiency with respect to the heat source is good.

Various floor heating devices other than those described above can be used. For example, a heater wire meanderingly wired on a heat insulating material, a heat medium circulating pipe, or a heat storage material unit used in combination therewith may be used. It is preferable to use the heat storage boards 31 and 32 and the planar electric heater 4 in terms of economy, ease of installation and removal, and the like.

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

As the electric heater 4, various linear heaters and planar heaters can be used.
A planar heater is preferable in that heat can be uniformly transferred over the entire surface of the substrate. For example, a plate-shaped product obtained by dispersing and blending conductive carbon or the like into rubber or plastic can be used.

After the floor heating device is laid, the surface floor material is fitted on the support member 5 as shown in FIG. In the present embodiment, for example, a metal floor material 6 in which a metal material having good thermal conductivity such as an aluminum plate is processed into a rectangular flat plate shape straddling the receiving portions 51 of the four support members 5, An example is shown in which a surface flooring is formed by using a thin (about 2 mm) decorative surface finishing material 7 that is closely fitted and stretched over. Such a configuration is preferable because the heat generated from the heat storage boards 31 and 32 can be transmitted to the floor surface in a favorable manner.

When removing the floor heating equipment constructed as described above, 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 heaters 4 are merely in a laminated state, they can be easily removed. When rearranging the room, the support members 5 are removed and re-arranged in an intended pattern. Board 3
If the electric heaters 1 and 32 and the electric heater 4 are laid, it is possible to easily cope with them.

[0020]

According to the floor heating equipment construction method and floor heating structure of the present invention as described above, the floor heating equipment once laid is crushed like a conventional buried floor heating equipment. Therefore, the floor heating equipment laid in a factory or the like can be easily laid again in accordance with the rearrangement of the mechanical device or the like.

Further, since the floor heating system is a prefabricated floor heating system employing the concept of a so-called free access floor without concrete casting or the like, the installation and removal of the facility can be easily performed, and the floor heating system used in a certain place can be used. It has the advantage that it can be reused in other places, and that it can easily cope with the case where new floor heating equipment is laid on the floor of an existing building.
