Description

The present invention relates to a partition wall provided with a passage that can be opened and closed by a door.

Conventionally, as a partition wall of this type, for example, a plurality of columns arranged at required intervals and a face plate arranged so as to close the space between the columns are known. Then, there are many cases in which a passage having no face plate is formed between specific columns and a door can be opened and closed in the passage (see, for example, Non-Patent Document 1).

In this type of partition wall, a door vertical frame is generally attached to a pair of columns forming a passage, and a door is arranged between the door vertical frames. The door vertical frame is a column from the passage side. It is fixed to the corresponding column by a screw screwed into the door.

In such a configuration, the screw for fixing the door vertical frame to the column is provided at a position hidden by the end face of the closed door, but the thickness of the partition wall is larger than the thickness of the door. In that case, if the structure is followed, the area that is not fixed to the support column by the screw becomes large, and that portion may rise from the support column or vibrate to generate a sound. Such a problem can be solved by screwing the area not hidden by the door to the support column, but with such a configuration, the number of screwed points increases and the man-hours for assembly work increase. , There is a concern that the screw head will always be exposed and spoil the appearance.
