Description

  The present invention belongs to the technical field of a method for attaching a building shutter device provided in an opening or the like of a building.

  In general, in this type of architectural shutter, there is a so-called heavy shutter device in which the left and right widths and vertical widths of the shutter curtain are increased, such as those provided in a wide opening. In this type of shutter, the shutter curtain is heavy. A winding drum that winds the winding drum and a member device such as an opening / closing device that rotationally drives the winding drum are also large and heavy. For this reason, when installing such a heavy shutter in a construction site, the operation | work which lifts each member to an installation location may be performed using lifting means, such as a crane. However, it takes a long time to install such a heavy shutter device even if the lifting means is used, it is difficult to position, and it can be quickly installed without delay due to restrictions on work deadlines. Is difficult and problematic.

As an improvement measure, a pair of left and right brackets are fixed to a fixing member (for example, a base material) fixed to the housing, both ends of the bracket are fixed to the brackets, a winding drum around which a shutter curtain is wound, and the bracket. There has been proposed an attachment method in which a shutter unit in a state in which an attached opening / closing device is incorporated in advance, the shutter unit is lifted (lifted) by a crane, and the fixing member is fixed to the upper part of the housing.
JP-A-7-208040

However, in the conventional device, the unitized member is connected to the crane and lifted and moved to the position where the shutter device is attached to the housing, so it is possible to shorten the work time. Since the construction is also constructed using a crane, the above method can be used as it is in an environment where the installation site of the shutter device is capable of moving the crane arm high, but the beam, roof, etc. Such a method cannot be used in a site where the arm is installed and the arm cannot be moved up.
In addition, in the conventional device, when the center of gravity of the shutter unit is taken into consideration, the take-up drum portion around which the shutter curtain is wound is heavy, and the lower end of the fixing member moves upward in the natural hanging state when suspended by a crane. Thus, it is assumed that the posture is inclined, and as shown in the drawing, it is considered that the fixing member cannot maintain a vertical posture. As described above, when the fixing member suspended in the inclined posture is to be fixed to the vertical surface of the housing, the fixing member is inclined to keep the fixing member along the vertical surface of the housing before the fixing work. It must be forced to change from vertical to vertical posture, and the change work is difficult because the operator must work by himself and at a high place and the winding unit itself is heavy. There is a problem that not only the installation time can be shortened sufficiently, but also work by a large number of workers is required.
Further, in the conventional device, the wire connected to the arm is connected to two places in the lengthwise direction of the fixing member, lifted and lifted, so that when the length of the shutter unit in the lengthwise direction is increased, the wire is further increased. There is a problem that it is difficult to achieve a balance, and it is difficult to perform a high-place work for setting the fixing member along the housing.

The present invention has been made in view of the above circumstances and has been created for the purpose of solving these problems. The invention of claim 1 is directed to a winding drum around which a shutter curtain is wound. in rotatably supporting building shutter device comprising above, on both sides of the building frame opening, whereas for fixing the pair of support members for supporting the winding drum, is wound around the shutter curtain to the winding drum The left and right ends of the take-up drum are respectively provided with support brackets that are rotatable relative to the take-up drum to form a drum unit, and the left and right support brackets of the drum unit are supported on both sides of the housing opening. Each support bracket has a pair of upper and lower protrusions that project toward the side of the housing opening. Pieces are formed respectively, each support member and that a pair of upper and lower lock receiving piece which projects to the opening side is formed respectively, the drum unit, a lifting means lifting the central portion, the left and right outside of the lifting unit The upper and lower locking pieces of each support bracket are placed on the upper and lower locking receiving pieces of the corresponding support member from above and temporarily held and fixed. This is a method of attaching the architectural shutter device.
The invention according to claim 2 is the mounting method of the architectural shutter device according to claim 1, wherein the lifting means is a forklift and the adjusting means is a chain block.

According to the first aspect of the present invention, the drum unit can be moved up in a stable posture with a good balance, and it can be easily and accurately attached to the housing, and the working time can be shortened.

The drum unit U configured in this manner is transferred to a position below the opening where the shutter curtain 1 serving as the installation site is mounted in a state where the drum unit U is placed on the transfer carriage 10. Here, the installation site of the present embodiment, have been installed beams and columns or the like is already the situation can not be you installation work extending the arm of the crane as the conventional ones (Patent Document 1) It has become. Therefore, by attaching the drum unit U based on the method in which the present invention is implemented, the drum unit U can be attached without using a crane as in the prior art, and the attachment operation is smooth and with good workability. It can be performed and is set so as to shorten the work time.

Below, the attachment method to the housing of the drum unit U in which this invention was implemented is demonstrated.
First, the drum unit U is biased to one of the angle members 8 (in this embodiment, on the front side in the drawing of FIG. 1), not directly below each angle member 8 provided on the side surface (side surface of the column). Set (transfer) to the specified position. Then, as shown in FIG. 6, a forklift 12 corresponding to the lifting means of the present invention is prepared on the front side of the drum unit U located in the middle of the longitudinal direction of the drum unit U and between the transfer carriages 10. The working unit 12a of the forklift 12 is inserted below the drum unit U, and the working unit 12a is moved upward to support the drum unit U in a lifted state. At this time, the fall prevention stand 11 similar to the fall prevention stand 11 set on the upper portion of the transfer carriage 10 is placed on the working unit 12a, whereby the drum unit U is kept in a stable state. As described later, when the drum unit U is moved upward based on the upward movement operation of the working unit 12a, the drum unit U is prevented from falling and is smoothly moved upward. It is set to be possible.

A chain that corresponds to the adjusting means of the present invention and is fixed above the opening when the drum unit U is moved up to some extent by the forklift 12 (for example, in a state where the drum unit U is lifted to a position near the lower position of the angle member 8 placement position). The operating chain 13a of the block 13 is wound around the drum unit U (see the phantom line in FIG. 6). The operating chain 13a is wound around the left and right outer portions of the lifting portion (supporting portion) by the forklift 12 (sites having a predetermined gap on both right and left sides of the lifting portion). At this time, it is set so that the curing material 13c is wound around the portion around which the operation chain 13a is wound, and thereby, as described later, the position adjustment of the drum unit U based on the operation of the operation chain 13b, or It is set so that the shutter curtain 1 can be protected when an auxiliary lifting operation is performed.
Further, as described above, the drum unit U is lifted while the posture of the curtain unit C is adjusted by the forklift 12 and the chain block 13, and at this time, the support bracket 3 provided on the curtain unit C is a take-up drum. However, since the support bracket 3 is not heavy enough to break the weight balance of the curtain unit C, the support posture of the drum unit U is not changed.
Reference numeral 14 denotes a bucket that can be moved up and down by an operator who operates the operation chain 13 b of the chain block 13, and a plurality of workers can also enter the bucket 14. The vertical movement operation can be appropriately performed according to the movement position.
Moreover, in this Embodiment, although the chain block is used as an adjustment means, it is good also as a structure using hoisting devices, such as a hoist.

  As described above, the drum unit U is set to the forklift 12 and the chain block 13 in a state where the angle unit 8 is moved up to the lower vicinity of the angle member 8, and thereafter, the forklift 12 and the left and right chain blocks 13 are set by the respective operators. While operating, the upper and lower locking pieces 3b and 3c of the support bracket 3 of the drum unit U are moved up to a predetermined upward position positioned above the other piece 8b of the angle member 8 protruding from the side surface of the housing. . In this upward movement state, the drum unit U is lifted by the forklift 12 so that the chain block 13 is supported in a lifted manner on the left and right outer sides of the lifting portion (supporting portion). Each is in a stable and supported state. Further, by operating the operation chain 13b of the chain block 13, the posture (position) of the drum unit U can be adjusted, and the operation of lifting up to a predetermined upward position (upward motion) can be performed in a stable posture. Is set so that it can be carried out smoothly and with good workability. In addition, the posture adjustment of the drum unit U by the chain block 13 is performed in a state of being supplementarily lifted with respect to the drum unit U lifted by the forklift 12, so that even if the drum unit U becomes heavy, the posture adjustment work ( A large force is not required for the operation of the operation chain 13b), the adjustment work can be easily performed with a small force, and the workability can be further improved while the work is performed at a high place, and the number of workers is small. Even so, it can be handled.

  In the upward movement state to the predetermined position, the support bracket 3 is located on the front side of the angle member 8, and from this state, the drum unit U is displaced toward the angle member 8 side by moving the forklift 12 forward. The upper and lower locking pieces 3b and 3c of U and the angle member other piece 8b are opposed to each other in the vertical direction. Subsequently, the working portion 12a is slightly moved downward to place the upper and lower locking pieces 3b and 3c on the other angle member piece 8b as shown in FIG. In this state, the upper and lower locking pieces 3b and 3c are locked to the other angle member other piece 8b from above, and the drum unit U is set to be supported by the angle member 8 in a temporary holding state. . Then, in this temporary holding state, the fixing operation of the drum unit U to the angle member 8 is completed by welding the angle member other piece 8b and the locking pieces 3b and 3c, respectively.

In the operation of locking the support bracket 3 to the angle member 8, the vertical position and the horizontal position of the left and right ends of the drum unit U can be finely adjusted by operating the operation chain 13 b of the chain block 13. However, since the fine adjustment is performed on the drum unit U lifted by the forklift 12 as described above, a small force is required, and thus the upper and lower locking pieces 3b, 3c and It is configured so that the locking operation with the angle member other piece 8b can be performed smoothly with a small number of workers, with good workability, and with high accuracy.
The left and right support brackets 3 are provided so as to be relatively rotatable with respect to the rotating shaft 2a of the take-up drum 2. Therefore, when the drum unit U is moved upward, the left and right support brackets 3 are freely rotated with respect to the rotating shaft 2a. The upper and lower locking pieces 3b and 3c are not necessarily held in the vertical position. In this case, the support bracket is not changed without changing the posture of the drum unit U itself in a state where the predetermined upward movement position is reached. By rotating 3, the upper and lower locking pieces 3 b and 3 c can be easily made to face the angle member 8, and the drum unit U can be attached more easily.

  Then, after the drum unit U is assembled in this way, in FIG. 1, the support plate 4a in which the opening / closing machine 4 is assembled is fixed to the left support bracket 3 by screwing and welding. The opening / closing machine 4 and the take-up drum 2 are linked and connected by winding the transmission chain 4c between the drive sprocket 4b and the driven sprocket 3e of the opening / closing machine 4. Further, a seat plate 1c is connected to the lower end of the shutter curtain 1, guide rails 5 are erected on both the left and right sides of the opening, a lintel 15 is fixed to the upper part of the opening, and the shutter is covered so as to cover the member on the upper part of the opening It is set so that necessary members such as fixing of the case 6 are incorporated, and further, necessary work such as electrical wiring is sequentially performed.

In the present embodiment configured as described, in the factory, the shutter curtain 1 is wound around the winding drum 2 to form the curtain unit C, and this is transferred together with other mounting members from the factory to the installation site. Therefore, transportation from the factory to the site becomes easy. And, since the support bracket 3 is incorporated into the curtain unit C at the installation site to form a drum unit U, the drum unit U is lifted by the forklift 12 to a predetermined position while adjusting the posture with the chain block 13, Even on the site where there is a ceiling, beams, etc., and a crane cannot be used like the conventional one, the heavy drum unit U can be easily moved up and attached to the housing, so that it can be used for general purposes. be able to.
Further, in this device, a drum unit U is constituted by the winding drum 2, the shutter curtain 1 wound around the winding drum 2, and the support brackets 3 at both left and right ends of the winding drum 2. The lifting operation is supported in a state where the lifting operation is assisted by lifting by the forklift 12 and lifting while adjusting the posture by the pair of chain blocks 13 respectively disposed on the left and right outer sides of the lifting portion by the forklift 12. Therefore, the posture is stable and positioning is easier than in the case of moving up in the state of simply suspending, and the stable posture is maintained even if the drum unit U is long, It can be moved up smoothly. In addition, since the drum unit U is configured to support the support bracket 3 on the angle member 8 on the side surface of the casing, the fixing work to the casing is facilitated, and the drum unit U can be attached to the casing with high accuracy. The work time can be shortened.
In addition, in this case, since the operation by the chain block 13 is performed in a state where the drum unit U is lifted by the forklift 12, the posture adjustment of the drum unit U based on the operation of the chain block 13 can be performed with a small force, It is possible to adjust with good workability even with a small number of workers while working at high places.

  Moreover, in the embodiment of the present invention, the forklift 12 is used as the lifting means, and the chain block is used as the means for assisting the lifting state while adjusting the lifted posture of the drum unit U. The attachment method of the invention can be easily realized using a highly versatile apparatus.

  Further, in this structure, the support bracket 3 provided in the drum unit U and locked to the angle member 8 fixed to the side surface of the housing is provided on the winding drum 2 so as to be relatively rotatable. The upper and lower locking pieces 3b and 3c can be easily corrected without changing the posture of the drum unit U, so that the shutter device can be mounted with higher workability. .
