Description

[Detailed Description of the Invention] Industrial Application Fields The present invention provides an automatic opening/closing method for automatically opening and closing ventilation holes in a foundation foundation, which automatically opens and closes ventilation holes formed in a concrete foundation foundation constructed on a site where a building is to be constructed. The device, more specifically, a mounting plate with an arbitrary number of ventilation windows formed thereon, is fixedly attached to the ventilation opening, and the ventilation windows are automatically opened and closed according to changes in temperature, for example, opening in the summer and closing in the winter. This relates to an automatic opening/closing device for ventilation holes in foundations.

BACKGROUND ART Conventionally, ventilation holes are generally formed in the foundations of buildings at appropriate distances in order to improve ventilation under the floor.

By the way, conventional ventilation holes are simply holes of an appropriate size made in the foundation foundation, and these ventilation holes are always open all year round, and the ventilation holes can be opened and closed by simply opening and closing them. There was no set structure that would allow it to be done.

Problems to be Solved by the Invention> As mentioned above, conventional ventilation holes are always open, so in summer, outside air enters the lower part of the floor through these ventilation holes, causing a problem with the environment of the building. However, in the winter, cold air from outside enters the lower part of the floor, and this cold air cools the indoor space from the lower part of the floor, resulting in a heating loss.

The present invention has been made in view of the above points, and its purpose is to open during the summer and close during the winter, depending on the temperature change K, without using power. An object of the present invention is to provide an automatic opening/closing device for a ventilation opening of a foundation, which is capable of automatically opening and closing the ventilation opening.

<Means for Solving the Problems> To achieve the above object, the basic foundation according to the present invention -3 - The automatic ventilation opening/closing device is a plate body formed in a size to cover the ventilation opening formed in the foundation foundation. An arbitrary number of ventilation windows are opened at appropriate intervals in the circumferential direction of the board, and the ventilation windows are fixedly attached to the ventilation opening part of the foundation foundation. The valve pieces of the same size are made in the same number and shape to correspond to the ventilation windows, and the space between each valve piece is formed into an open part, and the center part is made to face the plate of the mounting base plate. It comprises an on-off valve plate rotatably mounted on a shaft in the center, and an actuating element disposed by connecting an appropriate part of the on-off valve plate and an appropriate part of the mounting base plate, The element is made of a shape memory member formed to change its shape according to changes in temperature, and the movement of the shape of the operating element that changes depending on temperature is transmitted to the opening/closing valve plate to cause the closing/closing valve plate to change. The ventilation window is characterized in that the ventilation window is opened and closed by rotating it at a set angle in forward and reverse directions.

<Function> The present invention functions as follows. When the air temperature falls below a predetermined temperature (for example, 10°C), the actuating element expands, and this elongation movement is transmitted to the valve piece, so the opening/closing valve plate is pushed counterclockwise and rotated by a predetermined angle. Each valve piece closes each ventilation window. Furthermore, when the air temperature reaches a predetermined temperature (for example, 15 degrees Celsius) or higher, the actuating element contracts, and this contraction movement is transmitted to the valve piece, so the opening/closing valve plate is pulled clockwise and rotates by a predetermined angle. Since the opening is located at the position of the ventilation window, each ventilation window will be opened. In this manner, the opening/closing valve plate is rotated by a set angle in the forward and reverse directions according to changes in temperature to automatically open and close the ventilation window.

<Example> Embodiments of the present invention will be described below with reference to the drawings.
