Description

[Detailed Description of the Invention] The present invention relates to improvement of floor heating devices for various buildings including general residences.

Conventionally, this type of floor heating system has been constructed by constructing a steel plate 3 between the lower parts of wooden joists 2 attached to a large drawer 1, covering the joists 2, as shown in Fig. 1.
A heat insulating material 4 is supported on a steel plate 3 in between, a sheet-like heating element 5 is supported on this heat insulating material 4, and further this sheet-like heating element 5 is covered with a heat insulating material 6; Attach floor plate 7 to steel plate 3 on top of joist 2.
is attached with screws, etc. Like this, joist 2
When covered with a steel plate 3, this steel plate 3 has an inner surface. The difference in outside temperature causes condensation, and this condensation causes the wooden joists 2 to become stuffy, eventually causing complete rot over a wide area. In addition, since the heat insulating material 6, the sheet-like heating element 5, etc. are supported on the steel plate 3 passed between the joists 2, the number of components increases, the structure is complicated, and the cost is not only increased, but also the assembly work is troublesome. In addition, since the sheet-like heating element 5 and the heat insulating material 6 below it are isolated from the outside air by the steel plate 3, there are disadvantages such as poor drying efficiency and indoor humidity, resulting in poor heating efficiency.

The purpose of this invention is to prevent corrosion of the joists, improve their strength, make it easier to dry even if condensation occurs, and simplify the structure by reducing the number of component parts. To provide a floor heating device that can reduce costs, improve the efficiency of assembly work, and further improve heating effects by preventing indoor humidity and improving economic efficiency. This is what I am trying to do.

In order to achieve the above-mentioned object, the present invention forms a joist using a sectioned steel, and this sectioned steel joist is provided with side plates that are continuous to form a downward groove on both longitudinal edges of the floor plate mounting plate. , seat plates protruding downward from the lower longitudinal edges of the side plates are installed in series, and the seat plates of the shaped steel joists are installed on the upper surface of the joists to open the space spanning the length of the joists downward. A heat insulating material is supported on the seat plate between the joists, a gap is formed between the heat insulating material and the joist support material, a sheet-like heating element is supported on the heat insulating material, and the sheet-like heating element is covered. The floor plate is attached to the floor plate mounting surface of the shaped steel joist.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

In FIGS. 2 and 3, 11 is a bundle of stones, 12 is a bundle, 13 is a large drawer built over the bundle 12, and 14 is a joist. The joist 14 is made of shaped steel, and the floor plate mounting plate 1
Side plates 14b are connected to the lower sides of both sides in the longitudinal direction of 4a, and seat plates 14c projecting outward from the lower longitudinal edges of both sides plates 14b are connected to each other. A heat insulating material 16 made of polyurethane foam or the like is attached to the lower surface of the seat plate 14c, and the floor plate mounting plate 14a is positioned above,
A longitudinal space is opened downward, and the seat plate 14c is placed perpendicularly on the drawer 13 via the heat insulating material 16, and is attached with screws (not shown) or the like. A heat insulating material 18 made of polyurethane foam material or the like is supported on the seat plate 14c between these shaped steel joists 14, and a gap 17 is formed between the heat insulating material 18 and the drawer 13. This insulation material 1
A sheet-shaped heating element 20 is supported on the heating element 8 with a radiant material 19 such as aluminum foil interposed therebetween. In this sheet-like heating element 20, for example, as shown in FIGS. 4A and 4B, a heating element 22 with built-in electrode wires 21 is placed on a substrate 24 made of an insulating material via a radiant material 23 such as aluminum foil. .

A covering material 2 made of an insulating material that covers this heating element 22
The outer edge of 5 is sealed to the substrate 24, and the conductive wire 26 connected to the electrode wire 21 is connected to the substrate 24 and the covering material 2.
5 and is guided outward while maintaining a sealed state. The conductive wire 26 of each sheet-like heating element 20 is connected to the joist 14
The cable is led to the bottom of the bullbox (not shown) attached to a wall, etc., and the cable pulled out from the bullbox is connected to a controller (not shown) attached to the wall, etc.

A floor plate 27 is attached to the mounting surface 17 of the joist 14 by screws (not shown) or the like, covering the sheet-like heating element 20. A desired floor finishing material (not shown) is laid on this floor plate 27. Thus, heating can be performed by the heat generated by the sheet-like heating element 20.

Conventionally, as explained in FIG.
A steel plate 3 serving as a support plate was provided on the bottom surface of the floor assembly so as to cover the wooden joists 2 in order to support the heating elements 5 and the sheet-like heating elements 5. Since the steel plate 3 seals the space and isolates it from the outside air, it lacks dryness and becomes humid, which is a factor in reducing the heating effect.

Furthermore, the wooden joist 2 is constantly exposed to moisture due to dew condensation occurring at the contact interface between the wooden joist 2 and the steel plate 3 covering it, resulting in early corrosion. The present invention has modified the floor assembly structure in which the above-mentioned heat insulators and sheet heating elements are supported by steel plates, and while using the shaped steel as a joist, a seat plate connected to the shaped steel is used to support the heat insulating material, etc. Also serves as a means,
The interior space of the shaped steel joist is opened downward, and the heat insulating material is supported on the seat plate of the shaped steel joist, eliminating the need for the conventional steel plate that covers the bottom surface.
At least, it is possible to prevent dew condensation on the surface of the internal space of the shaped steel, and to eliminate sealing members such as steel plates, it is possible to increase air circulation to the inner layer of the floor structure and improve dryness. Therefore, even if condensation occurs, it is possible to Also, excessive moisture does not remain and therefore corrosion can be effectively prevented. In addition, the strength of the floor can be improved by using shaped steel as the joist. To restate, the above-mentioned shaped steel joist has side plates that are connected to each other in a downward groove shape on both longitudinal edges of the floor plate mounting plate, and seats that protrude outward from the lower longitudinal edges of both side plates. The plates are connected and the seat plate of this shaped steel joist is installed on the top of the joist support material to open the space spanning the length of the joist downwards, so even if condensation occurs, it can be dried quickly. Can be done. In addition, the heat insulating material and the sheet-like heating element above it are supported on the seat plate between the shaped steel joists, and the joists also serve as supporting members for the heat insulating material, etc., reducing the number of components and simplifying the structure. In addition to reducing costs, it is also possible to improve the efficiency of assembly work. Furthermore, since a gap is formed between the insulation material and the joist support material, this material can be exposed to the outside air and dried, preventing the room from becoming damp, improving the heating effect, and making it more economical. There are advantages such as being able to improve sexual performance.
