Description

The present invention relates to a shutter support structure, and more particularly to a support structure for a shutter device that includes left and right pillars erected on an independent foundation.

Patent Document 1 (FIG. 5) describes an independent shutter device that is attached to left and right independent pillars erected on an independent foundation. Such an independent shutter device has a simple beam structure that supports the shutter between the upper ends of each of the left and right pillars that are independent from the independent foundation. Such a shutter device is typically used as an openable / closable gate that partitions a private space (site) and a public space (road). Throughout this specification and drawings, A represents the road side and B represents the inside of the site.

As shown in FIG. 7, the support structure of such an independent shutter device is a structure that receives the entire wind load by each of the left and right pillars 1 ′ that are independent from the independent foundation 3 ′. In order to be prepared, the left and right pillars 1 'must be thick. If the cross-sectional dimension of the pillar 1 'is large, the effective area in the site will be narrowed accordingly.

And as shown in FIG. 7, in order to fix stably the lower end of independent pillar 1 ', pillar 1' is standingly arranged in the center part of the front-back direction (depth direction) of independent foundation 3 '. Therefore, a useless space having a depth dimension D1 is generated in front of the column 1 ′, that is, on the road side (A side).

Further, since the bracket that supports the end of the winding shaft of the shutter device is attached to the rear side of the column 1 ′, that is, the inside of the site (B side), in addition to the depth dimension D1, at least the expected dimension of the column 1 ′. The shutter device moves backward for (D2). Therefore, a useless space of the expected dimension D1 + D2 is generated on the road side (A side) of the site. When the column 1 'is thick, the expected dimension D2 increases accordingly.

If the cross-sectional area of the column becomes smaller, the support structure becomes more compact accordingly. For example, if the size of the pillar in the opening width direction is reduced, the site can be used more effectively. In addition, the space for two columns, the first column and the second column, is required, but the cross-sectional dimension of each column is smaller than the cross-sectional dimension of one conventional column, so the area occupied by the additional column is increased. Without making it possible, the advantages of the two front and rear columns described below can be utilized.

By standing the first pillar and the second pillar apart in the front-rear direction, the center of gravity of the shutter comes between the first pillar and the second pillar, and the first pillar and the shutter are placed in front of the independent foundation. It becomes possible to position, and the useless space ahead of the 1st pillar can be minimized as much as possible.

By using a bracket that supports the end of the winding shaft as a cross member, the number of parts of the support structure can be reduced and a simple support structure can be obtained.

By attaching the bracket to the side surface of the first column and / or the second column, the size of the support structure in the front-rear direction can be reduced, and a compact support structure can be obtained.

Effective use of the site can be achieved by one or a combination of the above effects.
