DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Field of the Invention The present invention relates to Tsukomi only equipment for mounting the building outer wall material in the building.

[0002]

2. Description of the Related Art In recent years, a curtain wall has been increasingly used as an outer wall material with an increase in the height of a building.

In order to install a curtain wall in a building, a curtain wall installed on the ground is vertically lifted so as to face a predetermined floor, and an operator pulls the curtain wall into the building side and attaches it to the outer surface of the building. The outer wall of the building is completed by repeating the work sequentially toward the upper floor.

Conventionally, a curtain wall is suspended by using a tower crane used for building a building.

[0005]

By the way, the method of hanging a curtain wall using a tower crane is affected by other processes using the tower crane, and vice versa. It may cause delay of the whole construction period.

[0006] In addition, if a tower crane is added or its installation period is extended, a considerable amount of work will be required, and the tower crane will be operated while the operator and the operator communicate wirelessly. Remains.

In addition, the use of a tower crane causes the speed of hoisting, lowering, and turning to be too fast to perform fine adjustment for mounting, so that collisions between curtain walls and breakage of a connecting portion occur, and as a result, It takes a lot of time to position each piece, and the work is difficult.

Further, the tower crane originally lifts heavy objects such as steel frames, and the hooks are heavy in weight. If the hooks shake due to wind or the like when the curtain wall is attached, the tower cranes cannot be stopped by hand. There is a problem that it is extremely dangerous.

[0009] Accordingly, an object of the present invention is carried out is narrowing hanging of the outer wall material without the use of a tower crane, the mounting of the outer wall material, safely Tsukomi only equipment of the performed building outer wall material in the high efficiency low cost To provide.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a steel frame 1 of a high-rise building.
And a pillar 2 and a beam 3 and a slab connecting the pillar 2 to each other, and a curtain wall is adopted as an outer wall material.

A hanging device 4 for hanging and attaching the curtain wall to the building frame 1 is mounted on the outer periphery of the upper portion of the building frame 1, and as shown in FIGS. A beam 5 projecting outward is fixed to each of the pillars 2 located at a position, and a horizontal rail 6 surrounding the outer periphery of the building frame 1 is attached to the lower surface of the group of beams 5 in a ring shape. A hoist 7 is mounted movably along the rail 6. In the case of a high-rise building, the hanging device 4 moves the mounting position upward as the construction of the building frame 1 progresses.

FIGS. 3 to 5 show a mounting structure of the straight portion of the rail 6 to the column 2, wherein the rear ends of two beams 5, 5 using a channel material are positioned on both sides of the column 2. The two beams 5, 5 are connected by a plurality of bolts 8 at the indoor side and the outdoor side sandwiching the column 2, and the columns 2 are clamped from both sides, so that the distal ends of the beams 5, 5 are horizontally moved outward. To protrude.

In order to improve the load-bearing strength of the beams 5, 5, angle members 9 supporting the lower surfaces of the beams 5, 5 are welded to both side surfaces of the column 2. An angle member 10 abutting on the indoor surface side of the column 2 is fixed between the end upper surfaces.

The rail 6 is made of I-shaped steel, and the upper flange 6a is fixed to the lower surface of the tip of the beams 5, 5 with bolts 11, and the hoist 7 is attached to the lower flange 6b as shown in FIGS. The hoist 7 is mounted in a suspended manner, is capable of running along the rail 6 by driving of the motor 12, and is configured to wind up and down the hook 13 via a wire rope. Since the operator operates the remote control at hand, safe work can be performed while always watching.

Further, since the hoist 7 has a capacity of less than about 1 t, the hook 13 is light in weight and can be sufficiently stopped by hand even if shaking occurs. Since it is not necessary to provide a bolt hole in the column 2 for mounting the beam 5, the strength of the column 2 is not reduced.

FIG. 6 shows the mounting structure of the arc-shaped portion of the rail 6 at the corner of the building frame 1, and the column 2
A pair of beams 5, 5 and 5 a, 5 a, 5 a, which are fixed vertically, are arranged so as to protrude in two directions perpendicular to each other, and a rail 6 is attached to a tip of the lower beams 5, 5 by bolts 11.
Directly fixed at.

The fixing of the beams 5, 5 and 5a, 5a to the column 2 is the same as the structure shown in FIG. 3, and the same reference numerals as those in FIG.

An interval is generated between the tip of the upper beams 5a, 5a and the rail 6 by the height of the lower beams 5, 5.

For this purpose, an angle member 14 is erected and fixed at the end between the upper beams 5a, 5a, and the upper end of the suspension bolt 15 is fixed to both ends of the angle member 14, and the suspension member fixed to the lower end of the suspension bolt 15 is fixed. The upper flange 6 a of the rail 6 is suspended by the metal fitting 16.

The hanging bracket 16 is formed by providing a notch 17 at the lower part of the metal plate to which the upper flange 6a of the rail 6 is fitted, and is inserted into the upper flange 6a from the end of the rail 6 in advance. Install it.

FIG. 8 shows an example in which the rail mounting structure is unitized. The upper and lower H-shaped members 31 and 32 are connected by a vertical member 33, and the beam 5 is projected and fixed to the upper H-shaped member 31.
The H-shaped members 31 and 32 are fixed to the column 2 by connecting them with bolts 36 with the column 2 sandwiched between the receiving members 34 and 35.

By unitizing the mounting structure in this way,
The work of moving the rail 6 upward with the progress of the frame work becomes easier.

The hanging device according to the present invention is constructed as described above. In order to construct the building frame 1 and to attach the curtain wall A to the outer surface of the frame 1, the hanging device is mounted on the outer periphery of the upper portion of the building frame 1. The rail 6 surrounding the periphery of 1 is attached.

To mount the rail 6, the beams 5, 5a are fixed to the column 2 so as to protrude outward, and the beams 5, 5a
The rail 6 may be fixed to the lower end of the tip of the building. The rail 6 may be a linear one having a predetermined length and an arc-shaped one positioned at a corner portion of the skeleton 1 and connected by a joint to form a building skeleton. Along with the ring surrounding the circumference of 1,
The required number of hoists 7 are mounted on the rail 6.

FIG. 7 shows a state in which the curtain wall A is suspended and attached by the hoist 7. The curtain wall A is suspended vertically by the hooks 13 of the hoist 7 via the suspenders 21, and is attached to the rail 6 of the hoist 7. The curtain wall A is brought to the building position by the movement along, and the worker may retract the curtain wall A and attach it to the building frame 1.

The rail 6 is provided in an annular shape so as to surround the periphery of the building frame 1, and the hoist 7 is movable along the rail 6, so that the curtain wall A is located at a required position on the outer surface of the building frame 1. The hoist 7 can be easily positioned finely by setting the hoist 7 to the hoisting, hoisting, and moving at double speed with reduction.

The hanging device can be used exclusively for mounting the curtain wall, so that the tower crane can be used exclusively for processes such as steel frame assembly, and when the mounting of the rails 6 is completed, the tower crane can be disassembled. Shortening is also possible.

[0032]

As is evident from the foregoing description, according to the invention, on both sides of the pillars of the building structures to position the rear end of the two beams, the coupling both beams with bolts, the beam on both sides surfaces of the pillar the angle member for supporting the lower surface were fixed in, since the fixing of the angle member that abuts on the interior surface of the pillar between the rear ends of the beams, the load bearing strength of the two beam rail is fixed to the distal portion
The degree improves. It is also provided to surround the building frame.
The external wall material can be hung by a hoist that can move freely along the rail, so that the tower crane can be dedicated to processes such as steel frame assembly, shortening the overall construction period and reducing costs, and furthermore, the hoist can be used for the external wall material. It can be used exclusively for mounting, and shortens the work period for mounting outer wall materials.

Further, the hoist is small in size and the weight of the hook used is light, and when the outer wall material is hung, it can be sufficiently stopped by hand even if swaying due to the wind occurs, and the safety of work can be improved. .
