Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a structure that prevents condensation that tends to occur on the inner surface of a concrete basement.

[Conventional technology]

Conventionally, in many cases, the ceiling of a basement doubles as the floor of the first floor of a house, but apart from forming a basement in the entire area below the floor, there are cases in which the basement is formed in a part of the area below the floor. , construction such as floor finishing is frequent. In this case, if the basement, including the ceiling, is formed in advance into a box shape and buried underground, the house built above the basement can be built in the same manner as in a normal case without a basement. In addition, if the box is pre-produced in a factory as a plurality of box pieces, the basement can be easily assembled on site without requiring labor for waterproofing work. Such a box is preferably made of concrete from the viewpoint of durability such as rust prevention and ease of maintenance (Utility Model No. 53-1999).
(See Publication No. 117707, Publication No. 110151 of 1982, etc.).

[Problem that the invention attempts to solve]

However, in our country's climate and climate, concrete basements like the ones mentioned above are prone to condensation on their interior surfaces, and unless forced ventilation is provided,
There are problems that seriously impede storage and habitation.

[Means for solving problems]

The present invention embeds a heater in the floor and side walls of a box-shaped concrete basement assembled with a plurality of reinforced concrete box pieces (hereinafter referred to as box pieces), and connects the heater from one of the side walls to the floor. To provide a dew condensation prevention structure for a concrete basement, characterized in that the heater is arranged in a meandering manner through the box piece and extends to the other side wall part, and the heater is arranged in contact with reinforcing bars buried in the box piece. This solves the above problems without compromising the ease of forming a basement.

〔Example〕

Hereinafter, one embodiment of the concrete basement dew condensation prevention structure of the present invention shown in the drawings will be described.

FIG. 1 is a schematic vertical sectional view showing a concrete basement together with a house to which an embodiment of the present invention is applied; in the figure, 1 indicates the concrete basement;
Reference numeral 2 denotes a house, and a basement 1 is buried underground extending from below the floor of the house 1 to the outside of the house with its ceiling exposed from the ground. And also, basement 1 is the second
As shown in the figure, there are two square-shaped intermediate box pieces 3, one intermediate box piece 3 with a skylight 4 on the ceiling, and an intermediate box piece 3 with a doorway 5' on the ceiling and a staircase 5 inside. One box piece and two dish-shaped end box pieces 6 are waterproofly joined to form a box shape.

A heater is embedded in the floor 7 and side wall 8 of the basement 1. That is, as for the inside of the floor part 7 and side wall part 8 of the intermediate box piece 3 reinforced by the reinforcing bars 10, FIG. As is clear from FIG. 3, a heater 9 consisting of a hot water pipe is arranged in a meandering manner, and the floor 7 of the end box piece 6 is similarly arranged.
A heater (not shown) is embedded throughout the side wall portion 8. The heaters 9 in each box piece are connected in parallel or in series to a heat source (not shown), so that the inner surfaces of the floor 7 and side walls 8 of the basement 1 can be uniformly heated above the dew point. There is.

Note that a heating wire can also be used as the heater 9. Further, the heater 9 can also be buried in the ceiling if necessary.

[Effect of idea]

As mentioned above, the concrete basement condensation prevention structure of the present invention has a heater embedded in the floor and side walls of the concrete basement.
The heater can heat the inner surface of a concrete basement above the dew point temperature to prevent condensation on the inner surface, and by placing the heater in contact with the reinforcing bars embedded in the box piece, the heat from the heater can be transferred to the reinforcing bars. It has great practical effects such as being able to diffuse and conduct efficiently throughout the box piece and heat the inside of the basement efficiently and quickly. Coupled with the fact that it does not compromise the advantages of the assembled basement, it has high practical value.

[Brief explanation of the drawing]

Fig. 1 is a schematic vertical sectional view showing a concrete basement together with a house to which an embodiment of the present invention is applied; FIG. 3 is a schematic diagram of the arrangement of the heaters, showing the floor and both side walls of the box piece of FIG. 2 in an exploded view. 1... Concrete basement, 3, 6... Box piece, 7... Floor, 8... Side wall, 9... Heater.

Claims (1)
