Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing an outer wall panel using a cableway and a device therefor when the outer wall panel is attached to a steel frame or the like.

[0002]

2. Description of the Related Art Conventionally, a crane installed on the ground or the top floor of a building is used for hoisting and carrying outer wall panels, base metal fittings, etc. at a construction site. Recently, traverse rails are temporarily installed on the outer peripheral surface of the skeleton using columns and beams of the skeleton, and a trolley equipped with a hoisting device is run to move an object to a predetermined place. In the case of the former (crane),
Despite the fact that the weight of the object is too small compared to the capacity of the large crane, there is no other way to use it, so it is currently used without help, and the installation period of the large crane is long and wasteful. There is a problem. In the case of the latter (traverse rail), it takes time and trouble to install the traverse rail or to relocate to the upper floor or a large crane is required. Further, since the weight of the entire system including the traverse rail becomes large, there are many problems to be solved, such as a restriction on the connection with the skeleton or a case where the skeleton side needs to be reinforced.

[0003]

In order to solve the above-mentioned problems of the prior art, for example, a method is conceivable in which a wire rope is attached to the outer peripheral surface of the body and the wire rope is used as a traverse rail to carry an object. However, when a wire rope is stretched between both ends of a frame like a cable crane or cableway used in the field of civil engineering and forestry, there are the following problems. When carrying an object, the main rope draws a parabola, causing a large central sag (deflection). Therefore, a large displacement occurs in the vertical direction with the movement. When a large tension is applied to the main rope in order to suppress the central hanging amount, it is necessary to make the wire rope used for the main rope thick and to consider the strength of the skeleton supported at both ends of the main rope. As a result, the equipment weight is significantly increased and the advantage of using the wire rope is lost. Therefore, it is an object of the present invention to provide a method of constructing an outer wall panel using a cableway and a device therefor, which reduces a central hanging amount which is a problem when a wire rope is used and has a light equipment weight.

[0004]

As a means for technically solving the above-mentioned problems, the present invention is a method of attaching an outer wall panel to a steel frame body, in which a main rope is provided on an outer peripheral surface of the steel frame body via an intermediate support member. And the traverse movement device is installed in a stretched state, the outer wall panel is hoisted and laterally moved by this traverse movement device, and the outer wall panel is attached to a predetermined position. To do. Further, according to the present invention, a wire rope is laid across the outer peripheral surface of the steel frame body in a stretched state via an intermediate support member, a carriage block movably attached to the wire rope, and the carriage block is attached to the carriage block. A gist is an apparatus for constructing an outer wall panel using a cableway, which is provided with at least a lifting device.

[0005]

[Operation] Since the wire rope was laid horizontally on the outer peripheral surface of the steel frame body via an intermediate support member so that the wire rope could not be loosened, and the carriage block was movably attached to the wire rope and the lifting device was attached. The outer wall panel can be mounted at a predetermined mounting position by hoisting the outer wall panel and moving the carriage block laterally.

[0006]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows an embodiment of the present invention. A cableway 2 is provided on the outer peripheral surface of a steel frame body 1, and an outer wall panel 3 is lifted by this cableway 2 and moved to a predetermined place to be attached.

The cableway 2 is a main rope, for example, a wire rope 4 which is laid across both ends of the outer peripheral surface of the steel frame body 1, and an intermediate support attached to each column 1a for holding the wire rope 4 in a stretched state. A member 5 and a carriage block 6 mounted laterally movable along the wire rope 4,
A suspension beam 8 for suspending the outer wall panel 3 is attached to the carrage block 6 via a suspension rope 7. At this time, a method of reducing the amount of lowering of the main ropes can be considered by increasing the number of carriage blocks, or by increasing the distance between sheaves suspended in the main ropes in one carrage block.

The wire rope 4 is, as shown in FIG.
Both ends are drawn into the side surface of the body through the corner snatch blocks 9 and attached to a tensioning device 10 such as a chill hole or a lever block, and a predetermined tension is applied during use.

As shown in FIGS. 7 (a) and 7 (b), the intermediate support member 5 has a suspension ring 5b on an upper portion of a frame 5a, and a guide plate 5c is rotatably attached to a lower portion thereof. A concave groove 5d into which the wire rope 4 is dropped is formed on the upper portion of 5c, and a wire rope stopper 5e is attached.

As shown in FIGS. 4 and 5, the intermediate support member 5 is a spring-out metal fitting 11 which is locked to the column 1a of the steel frame body 1.
Is attached to the tip of the via the suspension ring 5b, and the metal fitting 11 is hung by a support rope 13 on a mounting plate 12 fixed to the pillar 1a.

The carriage block 6 is shown in FIG.
As shown in (b), a plurality of sheaves 6b (two in the illustrated example) are provided on the upper portion of the frame 6a, and the support shaft of the sheaves 6b is a retractable detachable member that rotates independently of the sheave rotation. Each stop arm 6c is attached. When the carrage block 6 laterally moves along the wire rope 4, the disengagement prevention arm 6c is provided with an intermediate support member 5c as shown in FIG.
Although it is in a positional relationship of abutting against the frame 5a, when it abuts, it is pushed by the frame 5a to rotate in the direction of arrow A in FIG. 6 (a), and after passing through the frame 5a, the return spring 1
It is possible to automatically return to the original position by 4. Therefore, the carriage block 6 can smoothly pass through each intermediate support member 5.

As shown in FIG. 5, the carriage block 6
The wire rope 15 for traverse rope is connected to both sides of the lower end of the wire rope, and the end portion of the wire rope 15 for traverse rope is shown in FIG.
As described above, the carriage block 6 can be laterally moved to the left or right by being drawn into the inside of the body through the saddle support bracket 16 and pulled by a drive device (not shown). As the drive device, for example, a capstan system, a winding system using two winches, or the like can be applied, and a self-propelled system provided with a drive source such as a battery can be sufficiently used.

The suspension beam 8 has chain blocks 17 at both ends as shown in FIG. 2, and suspends the outer wall panel 3 such as a curtain wall. At this time, the hanging ropes 7 are connected to each other by a simple method such as a shackle so that the hanging ropes 7 can be gradually shortened as the working floor rises. It becomes possible to do. Further, in order to protect the suspending rope 7 and perform a smooth traverse operation, a protective sleeve 18 which is rollable like a guide roller is attached to the suspending rope 7.

Explaining the mounting method of the outer wall panel 3, first, as shown in FIG. 1, the outer wall panel 3 is lifted by the crane C from the loading platform of the carry-in vehicle B, and once placed on the pop-out gantry D provided on the steel frame body 1. The outer wall panel 3 which is either lowered or stocked in advance inside the body is pulled out and prepared on the gantry D.

The carriage block 6 is laterally moved and positioned on the popping-out gantry D, and an operator in the body operates the chain block 17 to lift the outer wall panel 3 as shown by the phantom line in FIG. , The carriage block 6 is moved to the left as shown by the solid line arrow to be positioned at the mounting position, and the worker standing by at this position operates the chain block 17 again to gradually lower the outer wall panel 3. And attach it to the specified place. In this case, it is preferable that the carrage block 6 is of a self-propelled type and can be remotely controlled by radio or the like.

By repeating such an operation, the outer wall panel 3 can be sequentially mounted on the outer peripheral surface of the steel frame body 1 as shown in FIG. 1, and when the same floor is completed, the mounting work on the upper floors is sequentially carried out. That is, when work cannot be performed at the horizontal position of the wire rope 4,
By relocating to the upper floor, the work of attaching the outer wall panel 3 is continued up to the uppermost floor of the steel frame body 1.

To relocate the wire rope 4 to the upper floor, move the carrage block 6 up to the top of the gantry D,
Here, after the suspension beam 8 and the chain block 17 are removed and lightened, the wire rope 4 may be removed from the intermediate support member, moved to the upper floor and re-crossed. Since all the constituent members are of a weight that can be carried by an operator, they can be easily replaced without using a heavy machine such as a crane.

Not only the work for mounting the outer wall panel 3 as described above, but also the work for mounting the base metal, and the outer wall finishing work such as sealing and cleaning the outer wall by suspending the gondola E as shown in FIG. It is possible to use.
Therefore, a scaffold for finishing the outer wall is unnecessary. Although illustration is omitted, it can be installed on the lower surface of the outer peripheral portion of the temporary roof of all-weather type and used as a hoisting device around the outer periphery of the building or a scaffold moving device such as a gondola.

In the above embodiment, only the transverse movement is performed by power, and the vertical movement is performed by the manual chain block. However, the invention is not limited to this, and from the viewpoint of work efficiency, a power chain block or hoist is used. It is also possible to use. Further, in this embodiment, since the outer wall panel on the same floor is targeted, the lift is small, and since it is not recognized as a crane mechanism due to its configuration, it is not necessary to notify the legal institution required when it is installed on site. Sometimes. Furthermore, the mounting plate fixed to the pillar can be cut and removed by embedding it in the concrete slab after use.

[0020]

As described above, according to the present invention,
It is possible to provide a method for constructing an outer wall panel using a cableway and a device therefor, which reduces the central hanging amount of a cableway using a wire rope and has a light equipment weight. Since it can be carried around, it has the following excellent effects compared to the conventional traverse rail system. Installation and refilling can be done easily without using heavy machinery. Since the system weight is extremely light, the burden on the skeleton is small and it can be installed anywhere. The cost is much cheaper than steel rails. Since the large crane can be used for other work, the installation period of the expensive large crane can be shortened. Scaffolds such as gondola can be easily moved, improving the efficiency of external finishing work. Especially, the effect is great in a building with horizontal windows. It can contribute to making scaffolding for finishing outer walls.
