Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for forming a floor heating section at a required location on a concrete floor.

[Conventional technology]

To form a heating section on a concrete floor, form a recess,
A heater, stove, etc. is installed there, and either a flat thin object that is easy to attach and remove is installed on top of it, or a frame such as a tower is installed, or a structure in which a panel heater, etc. is installed on the floor. It had become.

[Problem that the invention seeks to solve]

Among the above configurations, the former has the disadvantage that the fire source is exposed, which is dangerous and may lead to fire. The latter also had the disadvantage of being a hindrance, and had the disadvantage of requiring enormous equipment costs.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention forms a recess in the concrete floor to accommodate the block-shaped surface heating device, stores the surface heating device in this recess, and has a layer above the surface that has good heat conductivity and is connected to the floor. A floor heating section is formed by providing a flush concrete layer.

[For production]

In the present invention, the floor is exactly the same as a normal floor surface, so it does not interfere with other work, and even if a large amount of water etc. is used for cleaning, it will not cause any trouble to the heating machine. It is safe, fireproof, and extremely easy to form.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for forming a floor heating section on a concrete floor according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory diagram showing a partially cutaway floor heating section formed by the above method, in which 1 is a concrete floor;
2 is a concave portion formed into an arbitrary shape such as a square, rectangle, triangle, or circle. To explain further, the recesses 2 are formed at appropriate positions on the concrete floor 1 and have a volume corresponding to the required amount of heat generation. In addition, the depth D is 10 to 300
It is a dragon position. 3.4 is a heat-insulating material (hereinafter simply referred to as a heat-insulating board) that is attached to the inner circumferential wall 2a and bottom surface 2b of the recess 2, and is made of, for example, rock wool, glass wool,
It is formed by molding or spraying one of phenol foam, polystyrene foam, polyethylene foam, vinyl chloride foam containing calcium carbonate, foamed concrete, foamed gypsum, calcium carbonate plate, temporary calcium silicate, etc. In addition, the thickness is 1. is 5-2
Although the density varies depending on the material, the thermal conductivity is 0.
It is preferably about 16 kcal/m·1)·°C or less.

Further, a heat insulating board 3 is fixed to the inner circumferential wall 2a with an adhesive. Note that the height H+ of the heat insulating board 3 used for the inner peripheral wall 2a satisfies D>H+. The vertical heating device is a surface heating device that is inserted into the space surrounded by the heat insulating board 3.4 of the recess 2, and heats the floor surface to about 30 to 150°C. To explain further, the surface heating element m5 is formed, for example, in a rectangular shape as shown in FIG. 2, with a height H2 of H+t+ and a width L2 of L1≧L2. Note that L+ is the width between the inner sides of the insulation board 3 of the recess 2. Furthermore, the surface heating device consists of an insulating, airtight, non-flammable container 6 and an electrode 18, and the container 6 is filled with a surface heating section and ears. That is, the surface heating part 1 has a cross section shown in FIGS. 3(a) and 3(b), and FIG. 3(a) shows a heat insulating material 8 having an insulating property inside a container 6 and electrically resistive particles densely packed thereon. ! (hereinafter simply referred to as a resistor) and an adhesive 13. To explain further, as shown in Fig. 4, the resistance weight is 10 particles that become the core of sand, gravel, obsidian, gemstone, etc.
1 to 300 meshes or more, for example, 3 to 101 mφ, and the outer surface is a coating film (hereinafter simply referred to as coating film) made of conductive paint.
1). In particular, the coating film 1) is preferably baked. The conductive paint is composed of a conductor 12 made of nickel powder, copper powder, silver powder, etc., an adhesive 13 made of insulating acrylic resin, etc., and an electrical resistor 14 made of one or more of carbon black and nichrome powder. It is. Note that the ratio of conductor 12 and adhesive 13 is 80%:
20%, and the electrical resistor 14 is added in an amount corresponding to the required temperature. In addition, in the fb1 diagram, the resistance weights are randomly mixed in the electrical conductor layer 15 as shown in FIG. The body 14 is removed. Further, the "plane heating section" is an arrangement of a large number of surface heating vibrators 16a formed as shown in FIGS. 7(a) to (C1) with a cross section as shown in FIG. 6. The hollow part of the insulating vibrator 17 is filled with a required amount of resistance weight (according to the amount of heat generated), and its opening is closed with an electrode 18. 19 is a bonding agent made of synthetic resin, concrete, mortar, calcium silicate, etc. It consists of one type.

20 is a finishing layer which is made of the same concrete as the flooring material and is made of one type of solid finishing cement or the like that is not mixed with gravel or the like; It is to be finished flush with floor 1.

Next, a method for forming floor heating on a concrete floor according to the present invention will be explained. First, a recess 2 is formed in a floor 1. Next, the heat insulating board 3.4 is fixed with an adhesive as shown in FIG. 1, and then the surface heating device stand is inserted into the recess 2 space. Next, the finishing layer 20 is laminated in the raw material state or in the form of a molded body, and the boundary portions are sealed to complete the process. Note that the electrode 18 has a waterproof structure on the floor or is built into a vibrator and is electrically connected to the outside.

What has been described above is only one embodiment of the floor heating forming method according to the present invention, and it is also possible to surround it with a waterproof film as shown by the two-dot chain line in FIG.
