Description

The present invention relates to a case reinforcing structure and a carrying method when carrying a shutter case.

The shutter case of a heavy shutter used for opening and closing a large opening (hereinafter referred to as "heavy shutter case") has a top plate, a bottom plate, and a front plate provided between a pair of left and right side plates to form a storage space for the shutter curtain. It is a box-shaped shutter case or a square case. The basic shape of such a heavy-duty shutter case is described in Patent Documents 1 and 2.

The heavy-duty shutter case is assembled at the factory and transported to the installation site, where the shutter device (left and right brackets above the building opening, the take-up shaft supported between the brackets, the shutter curtain wound around the take-up shaft, etc. It is attached to (so as to store and cover the switch, etc. supported by the drive side bracket).

The heavy-duty shutter case is made by stacking multiple cases for efficiency and space saving during the transportation process (transportation within the factory, transportation from the factory to the installation site) from the factory production to the installation at the site. It is often transported in a state. At this time, the weight of the upper case acts on the lower shutter case, but since the case plate is usually formed of a thin plate having a plate thickness of 1.6 tons, a load in the vertical direction is applied to the lower shutter. There was a risk that the case would be deformed. Restoring the deformed shutter case to its original shape on site takes time and effort, and reduces the efficiency of the shutter case installation work on site.

In the vertical load acting on the shutter case C, the force acting on the front side and both ends in the width direction is supported by the front plate 4 extending in the vertical direction and the left and right side plates 2 and 3. Further, the vertical load acting on the shutter case C is also supported by the intermediate reinforcing member 8 provided at intervals in the width direction of the shutter case C. However, the back side (rear end side) of the shutter case C covers the take-up shaft supported between the left and right brackets 12 and 13 installed above the opening of the building and the shutter curtain S wound around the take-up shaft. The rear side of the shutter case C is vulnerable to a vertical load as compared with the front side and both ends in the width direction.

In the shutter case C according to the present embodiment, a plurality of first bearing members 9 and 2 are located on the rear side (opening side) between the upper surface plate 1 and the lower surface plate 5 and have an interval in the case width direction. The support member 10 is provided so as to be removable. The first bearing member 9 and the second bearing member 10 are reinforcing members that oppose the vertical force acting on the lower shutter case C in particular when the shutter cases C are stacked, and the force in the compression direction of the reinforcing members. It suffices if it can support (vertical load), and it can be formed from a rod-shaped or columnar member. As shown in FIGS. 1 and 2, the second support member 10 is provided at both end portions in the width direction of the shutter case C, and the first support member 9 is two second support members at both end portions in the width direction.

The postures of the first bearing member 9 and the second bearing member 10 are not limited as long as they are provided so as to be stretched between the upper surface plate 1 and the lower surface plate 5.

As shown in FIGS. 3 and 4, the first bearing member 9 is a long member having an L-shaped cross-sectional view from the first side 90 and the second side 91, and the upper end is the upper reinforcing member 6 and the intermediate reinforcing member. The lower end is detachably connected to the rear end of the upper portion 80 of 8 by simple welding, and the lower end is detachably connected to the rear portion of the lower portion 81 of the intermediate reinforcing member 8 by simple welding. In the present embodiment, since the upper end of the first bearing member 9 is connected to the upper reinforcing member 6 of the rear end of the upper surface plate 1 (located behind the rear end of the lower surface plate 5), the first bearing member 9 is connected. Reference numeral 9 extends between the upper surface plate 1 and the lower surface plate 5 in an inclined posture (inclining downward toward the front). The first bearing member 9 can bear a vertical load acting downward on the rear portion of the upper surface plate 1 by stretching between the rear portion of the upper surface plate 1 and the rear portion of the lower surface plate 5. It is possible to prevent deformation of the rear portion of the top plate 1 when the shutter cases C are transported in a stacked state.

Welding of the upper and lower ends of the first bearing member 9 is such that the first bearing member 9 can be easily detached from the shutter case C by applying an impact with a hammer or the like, so that the first bearing member 9 can be easily removed at the site. The member 9 can be removed. Since the first bearing member 9 is welded to the upper surface plate 1 and the lower surface plate 5 via the reinforcing members (upper reinforcing member 6, intermediate reinforcing member 8) built in the shutter case C in advance, the first bearing member 9 is welded to the upper surface plate 1 and the lower surface plate 5. It is not necessary to newly provide a reinforcing member in order to attach the 9, and since it is indirectly attached to the upper surface plate 1 and the lower surface plate 5 via the reinforcing member, the welding is broken at the site and the first bearing member 9 is attached. When detached, the upper surface plate 1 and the lower surface plate 5 are not damaged or deformed.

In the present embodiment, the upper end of the first bearing member 9 is connected to the upper portion 80 of the upper reinforcing member 6 and the intermediate reinforcing member 8, but the upper end of the first bearing member 9 is connected only to the upper reinforcing member 6 or the middle. It may be detachably connected only to the upper portion 80 of the reinforcing member 8. In the present embodiment, the lower end of the first bearing member 9 is connected to the lower portion 81 of the intermediate reinforcing member 8, but the lower end of the first bearing member 9 is connected to the lower reinforcing member 7 or the lower reinforcing member 7 and the middle. It may be connected to the lower portion 81 of the reinforcing member 8.

In the present embodiment, the first support member 9 is attached in the case width direction according to the position where the intermediate reinforcing member 8 is provided, but the first support member 9 is attached at a position different from that of the intermediate reinforcing member 8. It may be provided so as to be removable. In this case, for example, the upper end of the first bearing member 9 may be detachably connected to the upper reinforcing member 6, and the lower end may be detachably connected to the lower reinforcing member 7.

The second bearing member 10 is provided at both ends in the width direction of the shutter case C, and the upper reinforcing member 6 and the intermediate reinforcing member 8 do not exist at the portion where the second bearing member 10 is provided. As shown in FIGS. 1B and 2A, short receiving members 11 are fixed to both ends of the lower surface of the upper surface plate 1 in the width direction. As shown in FIG. 6, the receiving material 11 is a steel material having an L-shaped cross-sectional view from the horizontal side 110 and the vertical side 111, and by fixing the horizontal side 110 to the lower surface of the upper surface plate 1, the vertical side 111 is formed. It hangs down from the lower surface of the top plate 1. The receiving material 11 is attached at a position so as not to interfere with the steady rest members 15 and 16 of the left and right brackets 12 and 13 and the support portion 17 of the steady rest members 15 and 16. The receiving member 11 is a reinforcing member that reinforces the upper surface plate 1 by preventing the second bearing member 10 from directly contacting or connecting to the lower surface of the upper surface plate 1.

As shown in FIG. 6, the second bearing member 10 is a long member having an L shape in cross section from the first side 100 and the second side 101, and the upper end is simply welded to the vertical side 111 of the receiving material 11. The lower end of the second bearing member 10 is detachably connected to the vertical side 72 of the lower reinforcing member 7 by simple welding. As shown in FIG. 5, in the present embodiment, the second bearing member 10 extends in a vertical posture between the upper surface plate 1 and the lower surface plate 5. The second support member 10 is stretched between the rear side portion of the upper surface plate 1 and the rear side portion of the lower surface plate 5 at both end portions in the width direction of the shutter case C, so that the second support member 10 is on the rear side of both end portions in the width direction of the upper surface plate 1. It is possible to bear a vertical load acting downward on the portions, and it is possible to prevent deformation of the rear portions of both end portions in the width direction of the top plate 1 when the shutter cases C are transported in a stacked state.

Welding of the upper and lower ends of the second bearing member 10 is such that the second bearing member 10 can be easily detached from the shutter case C by applying an impact with a hammer or the like, so that the second bearing member 10 can be easily removed at the site. The member 10 can be removed. Since the second bearing member 10 is welded to the upper surface plate 1 and the lower surface plate 5 via the receiving material 11 and the reinforcing member (lower reinforcing member 7) built in the shutter case C in advance, the second bearing member 10 is a second bearing member. Only a short receiving material 11 needs to be provided to attach the 10, and since it is indirectly attached to the upper surface plate 1 and the lower surface plate 5 via the reinforcing member, the welding is broken at the site and the second bearing member is attached. When the 10 is removed, the upper surface plate 1 and the lower surface plate 5 are not damaged or deformed.

The upper end of the second bearing member 10 may be brought into contact with the horizontal side 110 and the vertical side 111 of the receiving member 11, and the lower end may be detachably connected to the vertical side 72 of the lower reinforcing member 7 by simple welding. .. It has been confirmed that the second bearing member 10 does not come off due to an impact or vibration during transportation even in such a mounting mode.
