[0003]

In the floor heating shown in FIG. 4, a concrete section 1 in which a hot water circulation pipe 104 is buried is provided.
08 is insulated from the concrete slab 100 thicker than the concrete part 108 by the heat insulating material 102, so that when the circulation of hot water to the hot water circulation pipe 104 starts,
The temperature of the floor surface rises in a short time and the room can be heated. Therefore, it is suitable for heating a room that has a short use time and a long non-use time. However, in the floor heating shown in FIG. 4, since the concrete portion 108 is thinner than the concrete slab 100, when the temperature change of the hot water circulating in the hot water circulation pipe 104 or when the hot water circulation stops, the floor temperature is reduced in a short time. Change. For this reason, in a building such as a hospital where the usage time is long and it is necessary to keep the room temperature constant, it is necessary to strictly manage the circulation state and temperature of the hot water circulating in the hot water circulation pipe 104.

[0004] The floor heating of the structure shown in FIG.
Since the concrete portion 108 having a thickness of 80 to 100 mm is formed on the concrete slab 100 having a thickness of 20 to 180 mm, the weight of the entire floor increases. For this reason, in a high-rise building, it is difficult to adopt floor heating having a structure shown in FIG. Further, the floor heating shown in FIG. 4 is complicated in its construction. That is, after the wire mesh 106 is placed on the heat insulating material 102 laid on the concrete slab 100 on which construction has already been completed, the provided hot water circulation pipe 104 is connected to the wire mesh 106.

[0005]

The present inventors have studied to solve the above-mentioned problems, and as a result, the concrete slab 100 which mainly forms a floor has a concrete slab 10.
Since the reinforcing member made of iron or the like for reinforcing 0 is arranged in a mesh, if the hot water circulation pipe 104 is fixed to the reinforcing member with a wire or the like and is disposed in the concrete slab 100, the formation of the concrete portion 108 is unnecessary. And that the concrete slab 100 once heated is not easily cooled, and arrived at the present invention.

That is, the present invention relates to a frame heat storage structure which is reduced in weight so that it can be used also for floor heating of an upper floor of a high-rise building, wherein the frame heat storage structure comprises only one layer mainly forming a floor. the building frame body made of concrete slabs are arranged in net-like, and a reinforcing member made of iron or the like to reinforce the skeleton, as a heating element disposed along said stiffener
And a hot water circulation pipe, and is disposed in the body.
Hot water circulation pipe is fixed to the reinforcing member located on the bottom surface side of the skeleton and in the vicinity of about １ ／ of the thickness of the skeleton, and the bottom surface of the skeleton made of the concrete slab, A heat insulating material having a thickness smaller than the thickness of the heat storage member. In such present invention, the heating element can use the electrical heating wire, such as a two-chromium wire.

According to the present invention, the skeleton body to the heating element comprising a concrete slab which mainly forms the floor portion is provided, for storing heat supplied from the heating element to the precursor, group <br/> portion of the floor Heat to warm the surface is supplied from the skeleton. By the way, the skeleton is usually formed mainly of the floor of the house, and is formed of a concrete slab or the like which is thicker than the concrete portion 108 in which the hot water circulation pipe 104 shown in FIG. Therefore, the heat capacity capable of storing heat in the skeleton is larger than that of the concrete portion 108. Once the heat is stored in the skeleton, even if the supply of heat from the heating element provided in the skeleton is stopped, the heat for warming the base surface is reduced. It can be supplied gradually from the skeleton, enabling long-time heating. Further, as shown in FIG. 4, the concrete part 108 for burying the hot water circulation pipe 104 in the upper part of the skeleton can be made unnecessary, and the weight of the base including the skeleton can be reduced more than the structure shown in FIG. Can also be simplified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the drawings. FIG. 1 is a schematic diagram of floor heating, in which two systems of hot water circulation pipes 12 and 14 made of resin for heating the floor of a room 10 are provided. Hot water is supplied to each of the hot water circulation pipes 12 and 14 from a supply header 18 supplied from a hot water supply source such as a hot water tank via a hot water supply pipe 16, and the hot water that has passed through each of the hot water pipes 12 and 14 is supplied. Is returned from the return header 20 to the hot water supply source via the return pipe 22. Such hot water circulation pipes 12, 1
As shown in FIG. 2, the base including the floor and the like of the room 10 in which the room 4 is disposed is mainly formed by a concrete slab 24 as a frame, and the concrete slab 24 carries the strength of the base. The concrete slab 24 is provided with a reinforcing portion 26 for reinforcing the concrete slab 24. The reinforcing unit 26, as shown in FIG. 3, which reinforcements 27 and 28 made of iron or the like is formed on the mesh, usually at the bottom side of the concrete slab 24
And it is arranged in the vicinity of about 1/3 of the thickness of the concrete slab 24 .

[0009] As shown in FIG.
The hot water circulation pipes 12, 12,... Are arranged along the reinforcing members 28 arranged in the longitudinal direction, and the hot water circulation pipes 12 are fixed to the reinforcing members 28 with fixing members (not shown) such as wires. Is done. In this manner, the bottom surface of the concrete slab 24 in which the hot water circulation pipe 12 is disposed is provided as shown in FIG.
Insulation material 2 thinner than the thickness of the concrete slab 24
The provision of 9 can prevent heat radiation from the bottom surface of the concrete slab 24. In the floor heating shown in FIG. 2, since the hot water circulation pipes 12, 12,... Are built in the concrete slab 24, the concrete section 108 in which the hot water circulation pipe 104 is embedded as shown in FIG. For this reason, normal interior decoration can be directly performed on the upper surface of the concrete slab 24. For example, the carpet 32 can be laid after the flooring 30 is formed. In addition, after forming a mortar layer on the upper surface of the concrete slab 24 to form a flat surface, flooring may be performed.

When the floor heating shown in FIG. 2 is formed, first, a reinforcing portion 26 for a concrete slab is formed in a mesh shape with reinforcing materials 27 and 28 such as iron materials at a predetermined position of a building, and the reinforcing portion 26 is formed. The hot water circulation pipes 12, 12... Arranged along the vertical reinforcing member 28 to be formed are fixed to the reinforcing member 28 by a fixing member (not shown) such as a wire. Next, concrete is driven into the reinforcing portion 26 on which the hot water circulation pipes 12, 12,.
Can form a concrete slab 24 having a predetermined thickness provided inside. The floor heating shown in FIG. 2 is a concrete section 1 in which a hot water circulation pipe 104 is embedded as shown in FIG.
08 can be eliminated, so that the structure can be simplified and reduced in weight as compared with the floor heating shown in FIG. 4, and the floor heating can be easily performed. For this reason, floor heating can be adopted also on the upper floor of a high-rise building.

In the floor heating shown in FIG. 2, when hot water is circulated through the hot water circulation pipes 12, 12,..., Heat of the hot water is stored in the concrete slab 24. Such a concrete slab 24 usually has a thickness of 120 to 180 mm and a weight of 300 to 450 kg per m ² , and has a large heat capacity. Therefore, even if the circulation of the hot water is stopped after the concrete slab 24 is once warmed, the room 10 can be heated by the heat supplied from the concrete slab 24. Therefore, even if the temperature of the hot water circulating in the hot water circulation pipe 12 changes, the concrete slab 2
In a building such as a hospital, which can absorb a change in hot water temperature, require a long use time and maintain a constant indoor temperature, the management of the circulation state and temperature of the hot water circulating through the hot water circulation pipe 12 is simplified. be able to.

Further, in the floor heating shown in FIG. 2, the concrete slab 24 is directly heated by hot water circulating through the hot water pipe 12. Therefore, as in the case of the conventional floor heating shown in FIG. 4, by heating the concrete portion 108 in which the hot water circulation pipe 104 is buried, the tensile stress based on the thermal expansion difference with the concrete slab 100 insulated by the heat insulating material 102 is reduced. The occurrence of cracks can be prevented. In the floor heating shown in FIG. 2, the effect on the entire building by directly heating the concrete slab 24 whose free expansion is regulated is smaller than the effect on the building due to natural temperature change according to trial calculations. Does not.

In the above description, as a heating method for heating a body such as a concrete slab, a hot water circulation method of circulating in a hot water circulation pipe has been described. However, the heating method is provided in a body such as a concrete slab. A method using heat from an electric heating wire such as a nichrome wire fixed with a wire or the like along the reinforcing material may be used. As such an electric heating wire, a wire obtained by covering a rubber insulator surrounding a nichrome wire, a copper / nickel alloy wire, or the like with a heat-resistant resin can be bent freely and can be preferably used. When such a heating system using an electric heating wire is used in place of the hot water circulation system shown in FIG. 1, electricity is supplied to the electric heating wire and the concrete slab 24 can be easily supplied to the concrete slab 24 during a time when inexpensive midnight power can be used. In the daytime, the room 10 can be heated only by radiating heat from the concrete slab 24 without energizing the electric heating wire, and the heating cost can be reduced.

[0014]

The precursor heat storage structure according to the present invention, by <br/> utilized floor heating bunches simplifies floor heating structure or the like, it is possible to easily perform construction. Moreover, because the Ru can be achieved even light <br/> dimerization skeleton heat storage structure, in the conventional floor heating structure can be adopted floor heating in the upper floors of tall buildings that could not be adopted. In addition, since heat is stored in the building with a large heat capacity, temperature changes such as hot water from the heating source that heats the building can be absorbed by the building, and the room temperature should be kept as constant as possible even if there is a temperature change in the heating source. Can be. Therefore, even in a building such as a hospital where it is necessary to keep the room temperature as constant as possible, it is possible to simplify the temperature control and the like of the heating source. Further, heat can be stored in the frame by using inexpensive midnight power, and the room can be heated by radiating heat from the frame in the daytime, so that the heating cost can be reduced.
