DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a semi-PCa balcony or a corridor of an apartment house using a PCa (precast concrete) member or a semi-PCa member.
The present invention relates to a support for a building exterior member, such as a construction member in a building exterior surface.

[0002]

2. Description of the Related Art Heretofore, in this type of shoring, not only assembling and disassembling at the site, but also attaching and detaching handrails and safety nets have to be carried out every time they are changed.

Accordingly, the above-mentioned conventional shoring works not only takes time for assembling and disassembling, but also has a problem that the work of attaching and detaching a handrail and a safety net is dangerous.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems, and an object of the present invention is to safely and easily use a rearrangement jig. It is an object of the present invention to provide a composite shoring for the outer surface of a building where work can be performed.

[0005] The composite shoring for the exterior of the building according to the present invention comprises:
A plurality of pillars, at least two large pullers mounted in parallel on the pillars, and fixed at least outside the outermost large pullstock and above and below the large pullstock; A plurality of posts, a handrail attached to these posts, and a safety net that is stretched over these posts and handrails and that is open at least at the same height as the lower side of the large pulling material. , And is characterized by the following.

[0006]

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-section steel, which is covered with a fire-resistant coated PCa plate 2.

On the beam 1, a semi-PCa balcony 3, which is manufactured in a factory or on the ground, is erected so as to protrude outside the building, and is constructed integrally with cast-in-place concrete 4.

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

As shown in FIG. 2, the shoring A mainly includes four aluminum pillars 5, a connecting rod 6 connecting these pillars 5, and a left or right pillar 5. The support members 7 are respectively laid horizontally on the upper ends of the pallets, a plurality of aluminum large pulling members 8 attached to the left and right support members 7 in a cross-girder shape, and provided at the lower ends of the pillars 5. It is composed of a jack 9. The large pulling members 8 are attached in parallel with each other. Note that a jack may be provided between the upper end of the pillar 5 and the support member 7.

Out of the outermost large pulling material 8 among the large pulling materials 8 of the shoring A, a plurality of columns 10 such as single tubes are attached so as to extend above and below the large pulling material 8. ing. Further, the column 10 is also attached to the outer end of the other large pulling material 8. A handrail 11 made of FRP is attached to the column 10. Further, a safety net 12 is stretched over these columns and handrails 11. The safety net 12 is opened at least at the same height as the lower side of the large pulling material 8, and the arm frame 17 of the refilling jig B described later is easily inserted into the lower side of the large pulling material 8. You can do it.

When the cast-in-place concrete 4 cast on the semi-PCa balcony 3 is hardened, the support A supporting the concrete is changed to an upper floor.

FIG. 3 shows a refilling jig B of the above-mentioned supporter A. 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 mounted at an intermediate position between the horizontal frames 14 and 16, but 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. The rear extension 17 of the arm frame 17
A counter weight 18 is mounted on the “a” so as to be movable in the front-rear direction (the longitudinal direction of the arm frame 17).

Rear extension 1 of left and right arm frames 17
At the rear end of 7a, a connecting frame 19 for connecting them is provided.
Are attached, and the leg frame 20 is suspended. 21 is a brace frame for reinforcement. Also, on the upper surface near the tip of the arm frame 17,
A hook member 17b is attached to the arm frame 1
7. Prevent the support A supported on the top from sliding down.

As is apparent from FIG. 4, a wheel 22 is mounted below the counterweight 18. The wheels 22 roll along the rear extension 17a of the arm frame 17. The above counter weight 18
Since a slight gap is formed between the counterweight 18 and the rear extension 17a, the counterweight 18 can move smoothly. 23 is a lateral displacement prevention roller. In FIG. 3, reference numeral 22a denotes an auxiliary wheel, which may be omitted when the wheel 22 is sufficient.

A gear motor 24 is provided below the center of the counterweight 18 so as to rotate a driving pulley 27 via a timing pulley 25 and a toothed belt 26 as shown in FIG. I have. The drive pulley 27 is screwed into 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 connection frame 19.

In FIG. 3, reference numeral 29 denotes a light receiving unit which receives a laser beam emitted from a portable optical remote controller 30, remotely controls the gear motor 24, and moves the counterweight 18.

Reference numeral 31 denotes a generator with a waterproof cover,
Power is supplied to the gear motor 24 and the like. Reference numeral 32 denotes a control panel which houses various controllers. Reference numeral 33 denotes an inclination indicator, which checks and displays the inclination state of the rearrangement jig B, particularly, the inclination state of the arm frame 17 by an automatic balance sensor (not shown).

The refilling jig B constructed as described above
As shown in FIG. 6, is appropriately hung on a hanging hook 35 of a crane (not shown) via a hanging wire 34 and lifted. At this time, the weight brace 18 is moved and adjusted by remote control using the optical remote controller 30 so that the arm frame 17 is horizontal.

On the other hand, the jack 9 of the support A is lifted to release the support of the semi-PCa balcony 3. continue,
The rearrangement jig B is moved in the direction of the arrow, and the arm frame 17 is inserted below the large pulling member 8 of the support A.

When the arm frame 17 is set below the large pulling member 8, the stay chain C (see FIG. 1) is removed, and the support A is lifted up by the jig B for refilling as shown in FIG. . At this time, the load of the shoring A is applied to the arm frame 17 to change the balance of the refilling jig B. Therefore, the counterweight 18 is moved again by the remote control, and the arm frame 17 is leveled. Adjust as follows.

When the work of holding the shoring work A by the refilling jig B is completed, the work is lifted and moved by a crane as shown by an arrow in FIG. 8, and is placed on a balcony on the upper floor as shown in FIG. Move.

After the shoring A has been replaced on the upper-floor balcony, the jack 9 is lowered again to perform positioning, as shown in FIG. Remove it. A new semi-PCa balcony (not shown) is set on the rehabilitated supporter A.

In the above embodiment, the support of the semi-PCa balcony has been described. However, the present invention is not limited to this, and may be any as long as it supports the member constructed on the outer surface of the building. . The PCa member of the present invention also includes a semi-PCa member that is partially cast in place.

[0025]

1) Since at least two large pulling members are mounted in parallel on a plurality of pillars, the arm frame of the jig for refilling is inserted below these large pulling members. When lifting, it can be lifted stably. (2) Since the safety net stretched over the support and the handrail is opened at least at the same height as the lower side of the large pulling material, the arm frame of the jig for refilling is enlarged from this opened part. It can be easily inserted under the pulling material.
