Description

  The present invention relates to a telescopic strut device for a partition wall, and more particularly, to a telescopic strut device used for supporting a panel body by standing between a ceiling and a floor surface in a simple construction type partition wall.

  Conventionally, a column is erected between the ceiling rail and the floor surface, which is installed on the ceiling, and the ground rail. Various partition walls are provided. Here, there is also provided one that directly supports the adjuster at the lower end of the support column so that it cannot move on the floor surface while omitting the ground rail. Such partition walls need to set the height of the column according to the height to the ceiling.In that case, prepare a long column in advance from the viewpoint of resource saving and workability, There is no construction method such as cutting, and telescopic struts that can freely change the height are adopted.

  For example, Patent Literature 1 discloses a telescopic support column in which an upper support column is slidably inserted into an upper portion of a hollow lower support column. This telescopic strut is fitted with a strut connector having a spacer portion on the upper part of the lower strut, a slider is mounted on the lower end of the upper strut, and the upper strut is slidably inserted into the strut connector, and the slider is It has a structure that can slide inside the lower support column. When constructing a partition wall using such an expansion / contraction support | pillar, a panel body is attached between lower support | pillars and a panel panel body is attached between upper support | pillars. However, as described above, since the spacer part or slider of the support post exists between the lower support and the upper support, the outer dimensions of the upper support must be set sufficiently smaller than that of the lower support. A large step is formed at the joint between the lower support column and the upper support column, and the lower support column and the upper support column are completely separated from each other by design, resulting in a discontinuous appearance. In addition, there is a problem that the upper support column unexpectedly falls into the lower support column.

Further, in Patent Document 2, a ceiling fixing bracket is inserted into the upper end portion of a support column so that the projecting length thereof can be adjusted, and an up-and-down bending having elasticity inward and outward formed on the side surface of the upper end portion of the ceiling fixing bracket. A structure is disclosed in which a piece is pressed against a side wall surface in a concave groove of a top rail to hold the column in an upright state. Since the partition wall of this patent document 2 has panel plates attached to both the front and back sides of the support column, the support column and the ceiling fixing bracket are only slightly visible from the joint, and there is a large step at the joint between the support column and the ceiling fixing bracket. Even if there is, it is a structure that does not affect the appearance. However, from the standpoint of construction to erect the column, while holding the column upright with the ceiling fixture lowered, the ceiling fixture is pushed up and pushed into the recessed groove of the ceiling rail, and then The work to fix the ceiling fixing bracket to the support by turning the screw with a screwdriver from the side at the upper end of the support is done at a very high position. It is also difficult to position.
