Description

  The present invention relates to the technical field of a method of mounting a bearing plate in an architectural weight shutter device installed at an entrance of a building such as a building.

Today, heavy shutters for buildings are sometimes built at openings such as entrances and exits of buildings, but such heavy shutters are generally provided on the ceiling side with a winding drum on which a shutter curtain is wound. It is rotatably supported on the left and right bearing plates (brackets), and the opening is opened and closed by the lifting operation guided by the guide rails of the shutter curtain accompanying the forward and reverse rotation of the winding drum.
In this case, the left and right bearing plates are generally fixed by welding to the side of the body frame, but welding work at high places is forced at the site and not only the workability is deteriorated. For example, in sites where walls, floors, ceilings, etc. have already been completed, or in existing sites, there are places that hate the generation of fire powder or flame (torch) during welding, and such powder does not get caught in such sites There is a problem that the work to cover the surroundings is forced. Furthermore, when there is no commercial power source for welding, there is a problem that the power source must be secured by preparing a generator or the like.
Therefore, a take-up drum having a shutter curtain incorporated in advance is prepared at the factory and transported to the site, and then the left and right bearing plates with the bearing mounting plate bolted to the support shaft of the take-up drum are assembled. After that, the one which lifts this and is bolt-fixed to the frame frame side is known (for example, refer to patent documents 1).
