Description

  TECHNICAL FIELD The present invention relates to a shutter reinforcing member fixing device provided at an opening of a building and a shutter reinforcing structure using the same.

  A shutter divided into a plurality of sets by a removable center pillar is used as a shutter that needs a large opening in a building where vehicles enter and exit.

  In recent years, the strength of the shutter itself has been improved and windbreak measures such as typhoons have been taken.However, especially in large factories and warehouses, the middle part of the large opening of the shutter is provided with a middle pillar, and the stat is not only positive pressure but also negative pressure. When the slat acts, the slat is pushed up on the outdoor side and swells, and even if it is fixed with metal fittings, the middle pillar of the shutter that is weak enough to be inserted into the floor may be broken or bent.

  On the other hand, in the shutter reinforcement device of Patent Document 1, one of the reinforcement members slightly shorter than the shutter height is engaged with the side frame (the guide rail in the present application), and the other is engaged with the erection (the middle pillar in the present application). By stopping, the reinforcing member is obliquely bridged, and the reinforcing member and the stat are locked at a plurality of positions in the middle part by using hook catches so that the stat does not come off the side frame.

  According to this method, the shutter can be reinforced and can be hung on the side frame when not in use, but when removing it, the hook catch must be removed from the stat, which is troublesome and Since one of the materials is fixed to a stake (middle pillar) that can be easily removed, if a large negative pressure is applied due to a storm, the strength of the weak stiffness (middle pillar) may be removed by applying force. . Furthermore, since the length of the reinforcing member is short and is not fixed at the lower end of the cubicle (middle column), a force is applied in the middle of the cubicle (middle column), so that it is easily bent or pulled out.

  The reinforcing structure of the sliding shutter disclosed in Patent Document 2 has one end rotatably attached to the upper end of one guide rail, the other end rotatably connected to an extensible adjusting member and the tip thereof, and the other guide rail. There is disclosed a shutter reinforcement structure including a detachable connecting member at a lower end of the shutter curtain which is guided by a rail and slides up and down.

  According to this method, a reinforcing material can be provided on the diagonal line of the opening of the shutter curtain to which the slats are connected. However, a groove for sliding the reinforcing material is required on the guide rail, and a guide rail suitable for this structure is newly provided. It is not a structure in which the center pillar is provided in the first place, and the effect of using the center pillar in this structure is not clear.
