Wheels are fitted to the lower side of the counter weight 18 so as to roll along the rear extended parts 17a. A light receiving part 29 receives laser beams emitted from a portable remote control 30, and a gear motor 24 is remote-operated to move the counter weight 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applicable to, for example, balconies and corridors made of semi-PCa such as apartment houses using PCa (precast concrete) members and semi-PCa members.
The present invention relates to jigs for hoisting building members, supporting works, and other materials and equipment on the outer surface of a building.

[0002]

2. Description of the Related Art For example, when a supporter supporting a PCa balcony is relocated to an upper floor, it cannot be lifted unless the supporter is pulled out of the building.

However, since the conventional hoisting device has a structure in which hoisting wire is simply hoisted upward, the hoisting wire interferes with the hoisting device and the like, and it is impossible to replace the support work directly below the balcony. Met.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art. The object of the present invention is to easily support even if there is an obstacle above. The purpose is to provide a hoisting jig for materials and equipment that can be hoisted safely and efficiently.

[0005]

A jig for hoisting equipment according to the present invention comprises at least two horizontal arm frames on which the equipment for building construction is placed, hoisting means for the arm frames, and And a means for maintaining the horizontal balance of the arm frame. The horizontal balance holding means comprises a counterweight movably arranged on the rear extension of the arm frame and a moving means for the counterweight. As the moving means of the counterweight, a ball screw arranged in parallel with the arm frame and a screw screwed on the ball screw to move in the axial direction while rotating are attached to the counterweight rotatably. And a motor for rotating the drive pulley. It is characterized in that the counterweight is moved by remote control. Also, the horizontal state of the arm frame is detected by a parallel sensor and displayed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a girder beam as a building frame made of H-shaped steel, which is covered with a fireproof coated PCa plate 2.

A half PCa balcony 3 manufactured in a factory or on the ground is erected on the girder 1 so as to project to the outside of the building, and is integrally constructed by cast-in-place concrete 4.

During the curing of the cast-in-place concrete 4, the half PCa balcony 3 is supported by the support A.

As shown in FIG. 2, the supporting work A is mainly composed of four aluminum pedestals 5, a connecting rod 6 for connecting each pedestal 5, and each left or right pedestal 5. From the support members 7 that are respectively laid horizontally on the upper ends of the, the large pulling members 8 made of aluminum that are mounted on the left and right support members 7 in the shape of a cross girder, and the jacks 9 that are provided at the lower ends of the pedestals It is configured. still,
A jack may be provided between the upper end of the pedestal 5 and the support member 7.

A strut 10 such as a single pipe is attached to the outer side or the outer end of the large pulling member 8 of the supporting work A.
A handrail 11 made of FRP is attached to the. Also,
A safety net 12 is stretched over the pillar 10 and the handrail 11.

When the cast-in-place concrete 4 cast on the half PCa balcony 3 is hardened, the supporting work A supporting the cast concrete 4 is transferred to the upper floor.

FIG. 3 shows a jig B for refilling the support A, in which the left and right vertical frames 13 are integrally connected by horizontal frames 14, 15 and 16. The horizontal frame 14 is attached to the upper end of the vertical frame 13, and the horizontal frame 16 is attached to the lower part of the vertical frame 13. The horizontal frame 15 is attached at an intermediate position between the horizontal frames 14 and 16, but it may be omitted.

An arm frame 17 is attached to the vertical frame 13 near the horizontal frame 16 in a direction orthogonal to the frames 13 and 16. The arm frame 17 has a length sufficient to support the support A. Rear extension 17 of the arm frame 17
A counterweight 18 is mounted on a so as to be movable in the front-rear direction (longitudinal direction of the arm frame 17).

Rear extension 1 of the left and right arm frames 17
At the rear end of 7a, a connecting frame 19 for connecting these
Is attached and the leg frame 20 is vertically installed. 21 is a brace frame for reinforcement. In addition, on the upper surface near the tip of the arm frame 17,
The arm frame 1 is provided with a hook member 17b.
7 Prevent the support work A supported on the top from sliding off.

As is apparent from FIG. 4, wheels 22 are attached to the lower side of the counterweight 18. The wheel 22 rolls along the rear extension 17a of the arm frame 17. Counter weight 18 above
Since a slight gap is formed between the rear extension 17a and the rear extension 17a, the counterweight 18 can move smoothly. Reference numeral 23 is a lateral deviation prevention roller. In addition, in FIG. 3, 22a is an auxiliary wheel, and may be omitted when the wheel 22 is sufficient.

A gear motor 24 is installed below the central portion of the counterweight 18, and as shown in FIG. 4, a drive pulley 27 is rotated via a timing pulley 25 and a toothed belt 26. There is. The drive pulley 27 is screwed onto a ball screw 28 and moves along the ball screw 28 while rotating. As is clear from FIG. 5, the ball screw 28 extends in parallel with the arm frame 17, and both ends thereof are fixed to the horizontal frame 16 and the connecting frame 19.

In FIG. 3, reference numeral 29 denotes a light-receiving portion, which receives a laser beam emitted from a portable optical remote controller 30 to remotely operate the gear motor 24 to move the counterweight 18.

Reference numeral 31 is a generator with a waterproof cover,
Power is supplied to the gear motor 24 and the like. A control panel 32 accommodates various controllers. Reference numeral 33 denotes an inclination display, which appropriately displays the inclination state of the refill jig B, in particular, the arm frame 17, by an automatic balance sensor (not shown).

Refill jig B constructed as described above
As shown in FIG. 6, it is appropriately hung from a hanging hook 35 of a crane (not shown) through a hanging wire 34 to be lifted. At this time, the weight brace 18 is moved and adjusted by a remote operation of the optical remote controller 30 so that the arm frame 17 becomes horizontal.

On the other hand, the jack 9 of the supporting work A is pulled up to release the support of the half PCa balcony 3. continue,
The refill jig B is moved in the direction of the arrow to insert the arm frame 17 into the lower side of the large pulling member 8 of the support A.

When the arm frame 17 is set on the lower side of the large pulling member 8, the retaining chain C (see FIG. 1) is removed, and as shown in FIG. .. At this time, since the load of the supporting work A is applied to the arm frame 17 and the balance of the reshuffling jig B changes, the counter weight 18 is moved again by the remote control operation so that the arm frame 17 becomes horizontal. To adjust.

When the holding work of the support work A by the reshuffling jig B is completed, it is hoisted and moved by a crane as shown by an arrow in FIG. 8, and is placed on the balcony on the upper floor as shown in FIG. To move.

After the support work A has been re-placed on the balcony on the upper floor, as shown in FIG. 10, the jack 9 is lowered again for positioning, and the spare chain C is attached, and then the re-mounting jig B is mounted. To remove. A new half PCa balcony (not shown) is newly set on the shuffled support work A. The PCa member of the present invention also includes a semi-PCa member that is partially cast on site.

[0024]

【The invention's effect】

1) Even if there is an obstacle in the upper part such as a support for a balcony, it can be easily lifted and refilled. 2) It is safe because it is possible to perform lifting work while keeping a balance. 3) Since the counterweight is moved by remote control to balance it, the operation is easy and quick. 4) Lifting work can be carried out safely and surely while confirming the balance by the balance sensor.
