DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inspection port closing device for hermetically closing an inspection port provided in a storage room under a floor or a ceiling of a building such as a house in an openable and closable manner.

[0002]

2. Description of the Related Art Conventionally, in order to improve the efficiency of cooling and heating, for example, an airtight sheet such as a polyethylene film is stuck on the indoor side of a house wall, ceiling, or floor so as to cover the inside of the room, thereby blocking outside air. This improves the airtightness of the room. On the other hand, houses have air-conditioning ducts and wires installed under the floor and behind the ceiling, and inspection openings for maintenance and management of these ducts and wires are provided on the floor and ceiling. ing. The inspection port provided on the floor is closed by a lid provided on a peripheral edge thereof and provided on the frame so as to be openable and closable, and the inspection port provided on the ceiling surface is:
A lid is openably and closably attached to a frame provided on the periphery of the inspection port and is closed.

[0003] In addition, an airtight sheet to be attached to a wall, a floor, or a ceiling surface is cut off at the periphery of the inspection opening opening on the floor surface and the ceiling surface so as not to block the inspection opening. The cut edge is airtightly attached using airtight tape. Then, a frame is attached so as to cover the portion where the airtight tape is attached.

[0004]

In order to remove moisture from the interior of the house, ventilation openings are provided on the outer walls and the like under the floors and ceilings so as to obtain air permeability. I have. For this reason, the underfloor and the underside of the ceiling are in communication with the outside air through the ventilation openings, so that the state is closer to the outside air state than the room covered with the airtight sheet.

In the above-mentioned conventional configuration in which the inspection opening is closed by the underfloor storage and the lid, it is possible to airtightly close the frame by an airtight member provided on the periphery of the underfloor storage and the lid. However, since the airtight sheet is hermetically attached to the periphery of the inspection port with airtight tape, that is, the airtight sheet attached to the inspection port is not airtightly connected to the frame, the dimensions of the inspection port and the frame are A gap is formed between the inspection port and the frame due to an error or the like, and the gap does not provide a high degree of airtightness in the room, resulting in a decrease in air conditioning efficiency.

Further, when the frame and the airtight sheet are airtightly connected by airtight tape or the like to close the gap in order to ensure a high degree of airtightness in the room, a lid for closing the inner peripheral side of the frame. It is difficult to provide the airtight tape so that the body and the airtight tape do not interfere with each other and damage the airtight tape, and the airtightness is not impaired. In addition, airtight tape between the inspection port and the airtight sheet ensures airtightness, and
There is a problem that the airtightness of the frame and the airtight sheet must be ensured with an airtight tape, and the construction work is complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide an inspection port closing device capable of easily closing an inspection port airtightly without any gap.
