Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a hoisting method for transporting a curtain wall to a mounting position on the outer periphery of a steel frame.

Conventional technology and its problems Conventionally, the work of installing curtain walls around the outer periphery of a steel frame was carried out by using a large crane to lift the steel frame, and lifting the curtain wall between the steel frame erection and transporting it to a predetermined position. .

Therefore, when a large crane is used for either lifting a steel frame or lifting a curtain wall, the other operation must be interrupted, which is extremely inefficient.

Furthermore, preparing another large crane specifically for lifting the curtain wall would be uneconomical due to the high equipment and transportation costs for the large crane.

Means for Solving the Problems The curtain wall hoisting method according to the present invention protrudes a gantry from a steel frame in the outer circumferential direction, and also installs a rail around the outer circumference of the steel frame to enable a hoist to run. A container equipped with a curtain wall is lifted by a crane and placed on a pop-up gantry, and a hoist lifts the curtain wall inside the container and transports it to a predetermined position on the outer periphery of the steel frame.

Embodiment This invention will be described in detail below based on an embodiment shown in the drawings.

A projecting pedestal 2 is protruded from the outer periphery of a steel frame 1 made up of columns and beams made of H steel, I steel, etc. Jumping gantry 2
, two H steels 3, 3 are extended on the left and right, and an H steel 4 is spanned between the tips of the H steels 3, 3, forming a U-shape. The upper ends of wires 5, 5 whose ends are connected to the tips of the left and right H steels 3, 3 are connected to clamps 6, 6 attached to the upper beams. H
In the middle part of the steel 4, there are two rails 7 on the left and right sides of the middle part,
7 is attached toward the steel frame 1 side. Stoppers 8, 8 are fixed to the tips of the rails 7, 7. An electric chain block 9 is arranged on the indoor side of the spring-out gantry 2, and an endless chain 1
0 is now ready to run. The chain 10 is hung parallel to the rails 7, 7 up to the H steel 4. 1
2 is a handrail.

Above the projecting gantry 2, a rail 13 made of I steel is installed horizontally around the outer periphery of the steel frame 1. The rail 13 is attached to the frame 1 by brackets 14. A hoist 15 is movably attached to the rail 13. Wheels 16, 16 are attached to the upper part of the hoist 15, and a motor 17
It is now possible to drive. In the hoist 15, a hanging metal fitting 18 suspended by a wire is movable up and down by a motor. The traveling position of the hoist 15 is that the hoist hanging core is the curtain wall 1.
It is directly above the lifting center of No.9.

The curtain wall 1 is placed on the above-mentioned pop-up gantry 2 by a large crane used for steel frame erection.
A container 20 loaded with a plurality of containers 9 is lifted and placed. The container 20 is assembled into a box shape using H steel or the like, and a vertical curing sheet is stretched around the outer periphery. A part of the floor of the container 20 can be opened and closed.
Wheels 21 are attached to the front, rear, left and right sides of the container 20, respectively. In such a container 20, a plurality of curtain walls 19 arranged left and right are mounted in a plurality of rows. The container 20 has wheels 21
is placed on the rails 3, 3 so that it can run on the rails 3, 3. The container 20 is connected to the chain 10 by a container traction clamp 21.

The curtain wall 19 is hoisted up by the hoist 15. Curtain wall 19 is container 20
The curtain wall 19 is sequentially lifted from the steel frame frame 1 side, transported to a predetermined position on the outer circumference of the steel frame frame 1, and the curtain wall 19 is installed. After transporting the curtain walls 19 lined up on the steel frame 1 side, the chain 10 is run to draw the container 20 to the steel frame 1 side,
The next row of curtain walls 19 may be positioned directly below the hoist 15. After that, the curtain wall 19 is transported again.

When installing the curtain wall 19 directly below the container 20, the floor of the container 20 may be opened and the curtain wall 19 may be suspended directly below.

After the installation of the curtain wall 19 inside the container 20 is completed, the container 20 is lowered to the ground by a crane, the curtain wall 19 is mounted again, and the above-described operations are repeated.

Although the present invention has the above-described configuration, for example, when a building has four sides, if a projecting gantry 2 and a hoist 15 are provided for each side, a crane can be used to move the projecting gantry 2 onto each projecting gantry 2. container 2
0 can be carried and the curtain wall 19 installation work can be carried out on each side.

Effects of the Invention The present invention has the above-mentioned configuration, and includes a spring-out gantry and a hoist that are inexpensive in terms of equipment and transportation costs, and a crane that loads a container equipped with a plurality of curtain walls onto the spring-out gantry. The curtain wall inside the container is then transported by a hoist to a predetermined position on the outer periphery of the steel frame.

Therefore, construction can be carried out at a low cost, and more cranes can be used for erecting steel frames, making construction more efficient.

In addition, since multiple curtain walls are lifted together by a crane and are heavy, they are less affected by wind pressure, and a hoist installed on the outer periphery of the steel frame is used to lift the curtain walls from the projecting gantry to a predetermined position on the outer periphery of the steel frame. Since the curtain wall is carried along the outer circumference of the building by the curtain wall, it is possible for workers to hold down the curtain wall on each floor, reducing the swing of the curtain wall in advance, and reducing the number of days when installation cannot be done due to wind compared to conventional construction methods. can do. In addition, worker safety can be ensured because load swing is reduced.
