Description

The present invention relates to a floor/wall inspection port installed when constructing a floor/wall, and its installation structure.

Inspection ports for floors and walls of buildings are sometimes installed in order to inspect the underside of the floor or the back side of the walls periodically or in the event of an abnormality. It is well known that a panel material is integrated inside a square frame (for example, see Patent Document 1). Furthermore, in the case of a wooden deck, one is known in which the same panel materials as the floorboards are lined up and fixed inside the four-sided frame so as not to give an unnatural appearance (see Patent Document 2).

However, in the conventional floor inspection port mentioned above, the straight frame materials that make up the four-sided frame are connected to each other with rivets, etc., so it is not possible to disassemble the four-sided frame and adjust the length of the frame material. , it was not possible to adjust the size of the square frame on site to accommodate the spacing of the joists and the width of the floorboards. Therefore, during construction, it was necessary to match the spacing between the joists to the size of the inspection port, or the inspection port manufacturer had to increase the variety of inspection port sizes.

In addition, if the conventional floor inspection hole mentioned above does not fit the width of the floorboard, the floorboard fixed inside the square frame may be cut to fit the size of the square frame, or the shape of the floorboard installed adjacent to the square frame may be modified. It required cutouts to match the contours of the four-sided frame, making it difficult to perform construction quickly. Particularly in the case of a four-sided frame, even if the outside dimension of the four-sided frame corresponded to the width of the floorboard, it was necessary to reduce the width of the floorboard fixed to the inside by the width of the frame material.
