Description

The present invention relates to a shutter case provided with a vibration damping member.

The window shutter device is attached to the outer wall of the building so as to open and close the space on the outdoor side of the window device, and since the shutter case that houses the shutter curtain is exposed outdoors, raindrops hit the shutter case when it rains May cause unpleasant noise. In order to prevent this, a damping member is provided on the upper surface of the shutter case (FIG. 11A, Patent Documents 1 and 2).

Here, in a state where the opening is closed by the shutter curtain of the window shutter device, both ends in the width direction of the metal shutter curtain are received in the left and right metal guide rails, and the metal at the lower end of the shutter curtain is received. The seat plate is in contact with or close to the metal lower frame, and inherently has a predetermined fire prevention performance. However, in order to secure a longer evacuation time and to prevent the spread of fire as much as possible, it is desirable to further improve the fire prevention performance.

The damping member provided on the upper surface of the shutter case is, for example, a sheet body obtained by bonding resin rubber and an aluminum plate material, and includes a resin element that is easily affected by high temperatures. In a mode in which such a sheet-shaped damping member is adhered to the lower surface of the shutter case upper plate, the damping member does not fall normally, but if the shutter case is exposed to a high temperature during a fire, the sheet There is a possibility that the shaped damping member softens and peels off from the lower surface of the case upper surface plate and falls to the lower portion of the shutter case (see FIG. 11B). When the damping member that has fallen to the lower part of the shutter case ignites, a flame may occur outside the case through the gap at the lower part of the shutter case.

By making the steel plate on the upper surface of the case into a double structure and providing the vibration damping member between them (Patent Documents 1 and 2), the vibration damping member can be prevented from falling, but the manufacture of the shutter case becomes complicated and difficult, This will increase costs.

In the shutter case having a vibration damping member on the lower surface of the case upper surface plate, the vibration damping member fixed (for example, bonded) to the inner surface of the shutter case is peeled off by heat at the time of the fire. Even if it is such a case, it aims at providing the shutter case provided with the structure where the said damping member does not fall.

The technical means adopted by the present invention to solve this problem are as follows:
The shutter case includes a case upper surface plate that covers a space above the winding shaft that is supported between the left and right brackets that extend from the outer wall of the building, and a case front plate that covers the space on the front side of the winding shaft. ,
Between the left and right brackets, one or a plurality of upper case cross members extending in the opening width direction so as to be close to or spaced apart from the lower surface of the case upper surface plate are provided,
A shutter case provided with a vibration damping member, on the lower surface of the case upper plate, is positioned between the lower surface and at least one upper case cross member, and a vibration damping member is fixed,
It is.

In one aspect, the damping member is a sheet body having a first width in the opening width direction and a second width in a direction perpendicular to the opening width direction, and the upper case cross member is the damping member. It is located below the middle part of the second width of the vibration member and extends in the opening width direction.
By configuring in this way, the upper case cross member can be positioned below the intermediate portion in the width direction including the center of gravity position of the damping member, and the damping member fixed to the lower surface of the case upper surface plate is peeled off Even so, the vibration damping member can be prevented from falling to the lower part in the shutter case by being caught by the upper case lateral member (see FIG. 10).

In one aspect, the said damping member is being fixed to the lower surface of the said case upper surface board by the adhesion | attachment means.
In one aspect, the vibration damping member is fixed to the lower surface of the case upper surface plate by a fastening element.
In a second embodiment to be described later, the vibration damping member is fixed to the lower surface of the case upper surface plate by an adhesive means, and the fastening element is sandwiched between the case upper surface plate and the contact plate. It is fixed with. Examples of the fastening element include rivets and screws.

  In one aspect, an upper case lateral member located in front of the case upper surface plate and above the case front plate is positioned below the vibration damping member, and the second width of the vibration damping member is A first portion in the direction is fixed to the lower surface of the case upper plate, and a second portion in the second width direction of the damping member is fixed to the inner surface of the case front plate.

  In the present invention, since the damping member is fixed to the lower surface of the case upper surface plate between the lower surface and at least one upper case cross member, the damping member is fixed to the lower surface of the case upper surface plate. Even when peeled off, it can be prevented from falling by being caught by the lower upper case cross member.
