Description

  The present invention relates to a mounting structure for simply fixing a shoji frame to a structure (base frame).

  Conventionally, to attach the shoji frame to the opening of the building outdoor wall, it was common to fix the shoji frame directly to the base member with screws, but it took a lot of work to install and changed the sash type There was a problem that became difficult.

  In particular, in a prefabricated house in a temporary housing in a disaster area or a temporary site office in a large-scale construction site, a shoji frame mounting structure that can be constructed early and has a certain degree of durability has been desired.

  In order to solve such a problem, several structures for easily attaching the shoji frame to the base member have been proposed. For example, in Patent Document 1 below, at least for the upper and lower frame members, a quadrilateral frame is configured using a member in which an opening groove directed inward along the longitudinal direction of the member is formed, and Each shoji is built in the four-frame frame adjacent to each other in the horizontal direction by using the shovel fitting recess of the intermediate interposed member installed using the formed opening groove or the opening groove of the upper and lower frame members. In addition, there is described a continuous shoji structure in which a horizontal pressing force is applied to each shoji by shoji pushing means disposed on at least one side of the left and right vertical frame members.

Moreover, in the following patent document 2, in the shoji frame mounting structure of the temporary house which attaches the shoji frame between the left and right columns by connecting the left and right vertical frames to the left and right columns, the pillar is opened inward in the in-plane direction. The cross-sectional shape has an opening and both side opening edge flanges. There is a shoji frame mounting structure for a temporary house that protrudes from both ends in the direction, is opposed to both side opening edge flanges and is mounted so as to be movable in the in-plane direction, and provided with a connecting screw for moving the connecting bracket in the in-plane direction. Are listed.

  However, in the invention described in Patent Document 1, after the shoji is fitted by the Kendon method, it is necessary to fix the shoji while adjusting the pressing force by the shoji pressing means disposed on the left and right vertical frame members. However, there was a drawback that required labor.

  In the invention described in Patent Document 2, in order to fix the vertical frame of the shoji frame to the left and right columns, the left and right connecting brackets are moved by adjusting the left and right connecting screws, and the left and right connecting brackets are moved to the left and right. Since it is intended to be fixed by press-contacting the pillars, there is a disadvantage that much labor is required for adjusting the right and left connecting screws.

  Therefore, a main problem of the present invention is to greatly simplify the operation of attaching and removing the shoji frame by enabling the attachment or removal of the shoji frame to be performed by a single rotation operation.

In order to solve the above-mentioned problem, as the present invention according to claim 1, an opening groove facing inward along the longitudinal direction of the member is formed by a pair of left and right opening edge flanges on at least the left and right sides of the building opening. A base frame is provided, and is a mounting structure for fixing the shoji frame to the base frame,
An engagement piece having an L-shaped cross section is formed on one side of the shoji frame, which is pivotally supported around the horizontal axis on the outer surface side of the left and right vertical frames, and is substantially opposite. A shoji comprising a rotating plate having an engaging piece having an L-shaped cross section formed on the other side and a rotating operation part extending outward from a substantially intermediate position of the engaging piece. Prepare the frame fixing bracket,
After installing the shoji frame while inserting the engaging piece of the shoji frame fixing bracket into the opening groove of the base frame, the pivot plate of the shoji frame fixing bracket is rotated, and the engaging piece is placed on the base frame. A shoji frame mounting structure is provided in which the shoji frame is fixed by being engaged with the inner surface side of the opening edge flange.

  According to the first aspect of the present invention, in a state in which the shoji frame is installed on the base frame, the shoji frame fixing bracket can be fixed by a single operation of rotating the rotating plate of the shoji frame fixing bracket. Since it becomes unnecessary, the installation work and removal work of a shoji frame can be greatly simplified.

  According to a second aspect of the present invention, there is provided the shoji frame according to the first aspect, wherein an inclined surface is formed at a peripheral edge portion in the rotation direction at the time of the shoji frame fixing operation with respect to the surface of the engaging piece on the shoji frame side. An attachment structure is provided.

  According to the second aspect of the present invention, when the shoji frame is fixed to the base frame by rotating the rotation plate, the inclined surface of the engagement piece serves as a guide when engaging the inner surface of the opening edge flange. Smooth installation work becomes possible.

  As described in detail above, according to the present invention, the attachment and removal of the shoji frame can be greatly simplified by allowing the shoji frame to be attached or detached by one rotation operation.
