Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention effectively utilizes the thermal efficiency of earth heating in a floor formed by an earth heating structure between soils under the floor and reduces abrupt temperature change. Related to a possible floor structure.

[Conventional technology]

The cold air from the soil beneath the floor was very uncomfortable for the residents, and no matter how much the living space was warmed by the cold air from the feet, the sensible temperature experienced by the human body did not rise. For this reason, it has been considered to form a soil heating unit that blocks cold air from the ground below the floor and warms the space under the floor between the soil under the floor.

[Problems to be Solved by the Invention]

However, in a house with an earth heating unit, the underfloor space is often heated entirely, so the indoor temperature is high on the south side where the solar radiation is received, and the temperature is low on the north side. Occasionally, the room on the south side was hot, but the room on the north side was cold, which was unhealthy. Further, the heating by the earth heating has a drawback that the running cost is high because the heating is effective during the operation.

[Means for solving the problem]

The present invention, in order to eliminate such defects, in the floor formed by the soil heating structure between the soil under the floor, the corrugated floor steel sheet disposed on the entire floor joists, and equal to or more than the convex surface of the corrugated floor steel sheet, The temperature of each living space inside the house is integrated by laminating and integrating a mortar layer, which is a heat storage layer and a protective layer formed to have a flat surface, and a floor material with good thermal conductivity, which is formed on the mortar layer. It is intended to provide a floor structure in which the temperature of the room on the south side is uniformed, the temperature rise during the daytime is moderated, and the nighttime temperature drop due to heat storage is prevented.

〔Example〕

An embodiment of the floor structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a partially cutaway explanatory view showing an example of a floor structure according to the present invention, in which 1 is a floor portion, and is a large pull 2, joist 3, floor steel plate 4, mortar layer 5, reinforcing plate 6, heat Floor material with good conductivity (hereinafter referred to as heat transfer plate) 7
It consists of More specifically, the floor portion 1 is composed of an attic space 8, an underfloor space 9, and a living space as shown in FIG.
10. The earth heating part B is formed on the floor part of the house A where the earth heating part B is formed, and the earth heating part B also serves as a heat storage part B ₁ made of a synthetic resin foam plate or the like, a pipe B ₂ , a mortar, etc. The heat radiating portion B ₃ and the pipe B ₂ are formed by a heat source B ₄ that supplies and circulates a heat medium. The floor steel plate 4 is a wide steel plate corrugated with a rational shape and is a general-purpose product such as a keystone plate or a deck plate.
A plurality of screws or nails are arranged and fixed to cover the entire surface of the joist 3. It has good thermal conductivity and strength, and when it is formed on the joist 3, it forms a space 4b. The heat radiation from the heating section B can be spread over the entire floor. The mortar layer 5 receives the heat from the soil heating part b and the solar radiation from the window A ₁ on the south side, and accumulates this heat energy and gradually radiates it, and the reinforcement of the floor part 1 . It is a part that functions as a heat storage layer and a protective layer that functions as a material.In addition to the mortar used to form the general outer wall, a mortar is mixed with an anticoupling agent and the mortar is destroyed by freezing and thawing in winter. Therefore, it is possible to prevent the pipe B _{2 from} being damaged or increase the amount of aggregate (gravel or the like) to further improve the heat storage effect. In addition, the formation is made to be equal to or more than the convex surface 4a of the floor steel plate 4. The reinforcing plate 6 is
It is adhered onto the mortar layer 5 by an adhesive agent (not shown) and serves as a base for fixing the heat transfer plate 7, and is, for example, plywood. The heat transfer plate 7 is made of a material having a certain degree of heat conductivity in order to collect the solar heat entering from the window A ₁ and store the heat in the mortar layer 5, and uses, for example, a concavity plate or a flooring. .

Here, the construction method of the floor structure according to the present invention will be described. First, 1.6mm on the floor base consisting of Daihiki 2 and joist 3
A floor steel plate 4 made of a thick deck plate I type is fixed via a plurality of screws. When the construction of the floor steel sheet 4 is completed, the mortar having the same composition as the outer wall is flattened by raising the convex surface 4a of the floor steel sheet 4 by 10 mm. After the mortar is completely dried and solidified, the reinforcing plate 6 made of plywood is placed and fixed on the mortar layer 5 with an adhesive, and then the plywood 6 that has been subjected to the joint process is pulled up and the construction is completed. To do. The surface of the plaster deck is to be polished at the end.

[Other Examples]

The above description is merely one example of the floor structure according to the present invention, and the floor structure can be formed as shown in FIGS. 3 (a) to (f). 3 (a) to 3 (f), (a) is a floor portion 1 from which the reinforcing plate 6 is removed, and (b) is a synthetic resin made of polyethylene sheet or the like between the mortar layer 5 and the reinforcing plate 6. Floor part 1 having a protective sheet 11 formed thereon, (c) shows a floor part 1 having a copper plate 12 formed between a mortar layer 5 and a reinforcing plate 6,
Figures (d) and (e) show that the mortar layer 5 is formed in the same manner as the convex surface 4a of the floor steel sheet 4, and in particular (d) shows the floor 1 without the reinforcing plate 6, and (f) shows mortar. It is the floor portion 1 that is finished with the layer 5 as the floor surface.

〔The invention's effect〕

As described above, according to the floor structure of the present invention, it is possible to mitigate the sudden temperature rise and fall of the living space on the south side.
It is possible to prevent uneven temperature distribution in each living space inside the house. Due to the heat storage function of the mortar layer, the temperature of the living space at night can be kept moderate without the temperature of the house becoming below zero. It can be a healthy house. Etc. effect,
There are features.
