Description

[Detailed description of the invention] The present invention relates to a foundation device, and more specifically, a net 3 is attached over the entire length of an opening 2 formed between a pair of opposing foundations 5, and the opening 2 is
This relates to a basic device comprising a door body 4 that can be freely opened and closed.

Conventionally, ventilation holes are provided in the foundation, but because the opening area is small, ventilation performance is poor and moisture tends to accumulate.

This invention was developed in view of the shortcomings of the conventional examples mentioned above, and its purpose is to effectively dehumidify the underfloor area through natural ventilation due to the large opening area, and to improve the cooling effect of the house. The purpose of the present invention is to provide a basic device that can increase the heat retention effect during the winter.

The present invention will be explained in detail below with reference to the accompanying drawings. As shown in Figure 1, a pair of foundations 5 facing each other and this foundation 5
A foundation device A is formed in a rectangular shape by a pair of foundations 1 that are adjacent to each other and face each other. The entire foundation 5 is made of concrete and has a ventilation hole 6 opened therein. The foundation 1 has a metal frame 1b made of iron or aluminum in an opening 2 that extends left and right above the ground B of the concrete foundation 1a (that is, an opening 2 formed over the entire length between the opposing foundations 5). is fixedly installed, and a net 3 such as a metal net is stretched over the opening 2. The upper end of a door body 4 is rotatably attached to the upper end of the metal frame 3 by a pin 7, so that the door body 4 can cover the indoor side surface of the net body 3. Furthermore, the door body 4 is provided with legs 8 that are foldable and extendable. However, in order to increase the heat retention effect under the floor in winter or to prevent rain from penetrating under the floor during rain, the door body 4 should be installed as shown in Figure 3a.
The opening 2 is closed by closing the opening 2. In addition, to enhance the cooling effect under the floor in the summer,
In order to dehumidify the floor under the floor after a rain, as shown in Figures 3b and 3c, raise the door body 4 and extend the legs 8 downwards. It is supported horizontally, and ventilation is provided under the floor via the net 3. Reference numeral 3a is a net with a part of the net 3 opened and detachably attached to this opening, and when inspecting the underfloor area, the net 3a is removed and inspection is carried out through this opening. Further, the door body 4 may be provided on the outdoor side of the net body 3.

What is shown in Fig. 4 is the other side of the present invention, in which a metal frame 1b is mounted on a concrete foundation 1a with only the footing part.
An opening 2 is provided in the metal frame 1b above the ground B, and a net 3 is detachably attached to the opening 2.

As described above, in this invention, a net is attached to the entire length of the opening formed between a pair of opposing foundations, and a door body that can be opened and closed is attached to this opening. The opening area of the floor is large, and sufficient ventilation performance can be obtained by opening the door body.In the summer, by opening the door body, wind can be blown through the floor under the floor, providing a sufficient cooling effect. After rain, ventilation through the opening allows sufficient dehumidification of the underfloor area, and even though the opening is large, the door can be closed during winter or rainy seasons. It can enhance the heat retention effect under the floor and prevent rain from blowing into the floor. In this way, the present invention allows for effective ventilation, increases the cooling effect of the house, and increases the heat retention effect in the winter.
