Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition wall structure.

[0002]

2. Description of the Related Art Conventionally, a partition wall is often used as a means for arbitrarily changing the space and layout of a room in a building such as a house, and a wall panel of the partition wall is erected and fixed at a desired position. Thereby, the room can be partitioned into a desired space. As the partition wall, for example, FIGS. 7 and 8A and 8B, FIGS.
(A) There is known a structure having a structure for vertically extending and fixing between a ceiling surface and a floor surface as exemplified in (b).

In the structure of the partition wall illustrated in FIGS. 7 and 8 (a) and 8 (b), an upper support (c) and a lower support are provided at desired positions on a ceiling surface (a) and a floor surface (a) of a room. (D) is fixed, and the upper and lower parts of the wall panel body (E) are fitted or loosely fitted in the upper support body (C) and the lower support body (D), and the upper end part has a built-in part. The upper and lower sliding means (f) stretches against the upper support (c), so that it is erected and fixed between the upper support (c) and the lower support (d).

In the partition wall structure illustrated in FIGS. 9 and 10 (a) and 10 (b), the upper support (c) has a groove (g) and the lower support (d) has a protrusion (h). The wall panel body (E) has a strut bolt (K) at the upper end and a groove (K) at the lower end. Then, the groove (U) at the lower end of the wall panel body (E) is fitted into the projection (H) of the lower support (E), and the extension bolt (K) at the upper end of the wall panel body (E) is fitted. ) Is stretched against the groove (g) of the upper support (c), and the wall panel body (e) is erected and fixed between the upper support (c) and the lower support (d).

[0005] Between the wall panel body (e) and the adjacent wall surface (sa), there is a cushion material (shi) as illustrated in FIG. 7 (b) or a cushion member (shi) as illustrated in FIG. 10 (b). There is provided a strut fixing means including a strut bolt (s) and a support member (s), and the cushion material (s) is used to adjust the gap and to reduce the impact on the wall surface (s) and to prevent damage. The fixing strength is improved by the strut fixing means.

[0006] The partition wall structure of the above-mentioned strut-fixing method is different from the partition wall structure which is erected along a rail body fixed in advance to the ceiling when the room is constructed. Since the wall panel can be arbitrarily moved to the position, the room partition can be formed more easily.

[0007]

However, FIGS. 7 and 8 (a) and (b) and FIGS. 9 and 10 (a) and (b)
The structure of the conventional partition wall as exemplified in (1) above has practically the following points to be improved. First, FIGS. 7 and 8
In the structure of the partition wall illustrated in (a) and (b), vertical sliding means (f) is required for fixing the wall panel body (e) in a stretched manner, and this vertical sliding means (f) is generally expensive. Not only does this increase the overall cost, but also the up-and-down sliding means (f) needs to be manually rotated with a tool and slid while rotating, which also requires time and labor for construction.
Further, since metal is used for the upper support (c) and the lower support (d) in this example, the sense of discomfort with the room is high, and the aesthetics of the room may be impaired.

On the other hand, in the structure of the partition wall illustrated in FIGS. 9 and 10 (a) and 10 (b), it is necessary to manually rotate the strut bolt (k) to strut and fix the wall panel body (e). In addition, since the rotation work for the strut also takes time and effort, improvement of workability is desired. Also, it is necessary to stick a board material (so) that hides the strut bolt (ke) if it is bare and it looks bad, but this board material (so) is usually attached to the wall panel body (o) Therefore, the wall panel body (e) had to be peeled off when it was moved, which required extra time and effort.

Further, a gasket is often used as a cushioning material between the adjacent wall surfaces, and this gasket is also not preferable in view of the room.
Even in the case of the strut fixing means including the strut bolt (s) and the support member (s), it is necessary to attach a board material (so) for improving the appearance, and it has been troublesome to peel off the board when moving. .

The invention of this application has been made in view of the above circumstances, and solves the problems of the conventional partition wall structure, and realizes improvement of workability without impairing appearance. It is intended to provide a new partition wall structure that can be easily relocated.
