Description

The present invention relates to a curing device and a curing method suitable for exterior construction of, for example, a high-rise office building.

Conventionally, in exterior construction of a high-rise office building or the like, a construction method in which an exterior material such as a curtain wall is suspended by a crane or the like may be applied. As the height increases, the possibility of strong winds increasing, and in the case of hanging work, the work may be interrupted or the work must be performed at the timing when the wind weakens, which may reduce the installation efficiency.

As a conventional technique for solving such a problem, for example, a curing facility as shown in Patent Document 1 is known. The curing equipment of Patent Document 1 cures the outer peripheral side of the exterior mounting work range in a state of being covered with a curing sheet. In this curing equipment, the curing sheet is hung and supported by a support provided on the building frame, and the curing pedestal is hung and supported below the curing sheet, and the curing pedestal is lifted by a lifting device to lift the curing sheet. It can be recovered up to the vicinity of the support.

Hereinafter, embodiments of the curing device and the curing method according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment.

(Embodiment 1)
First, Embodiment 1 of the present invention will be described.
As shown in FIGS. 1 and 2, the curing device 10 according to the first embodiment is applied to the installation work of the exterior material 2 on the outer peripheral portion of the high-rise office building 1 (building). The exterior material 2 is assumed to be a unit panel of an aluminum curtain wall in which glass is fitted in a mullion and integrated. In the figure, reference numeral 3 is a pillar, reference numeral 4 is a floor slab, and reference numeral 5 is a crane rail.

As shown in FIG. 3, the curing device 10 includes an overhang bracket 12 (support material) projecting outward from the floor slab 4 (building frame) and a guide suspension wire 14 suspended from the tip side of the overhang bracket 12. (Hanging material), lower guide 16 (fixing material), mesh sheet 18 (curing sheet), and winding mechanism 20 are provided.

The overhang bracket 12 is fixed to the floor slab 4 and projects outward from the end of the floor slab 4. A take-up mechanism 20, a guide suspension wire 14, and a lifting device 26 are suspended under the overhang bracket 12 in this order from the tip end side. A retaining wire 28 extending from the upper floor is connected to the tip of the overhang bracket 12. The lifting device 26 is a Telpher crane for lifting the exterior material 2, and can move laterally along a crane rail (not shown).

The guide suspension wire 14 is a wire extending several floors below (4 floors below in the example of FIG. 2) from the tip end side of the overhang bracket 12, and functions as a guide rail when raising and lowering the mesh sheet 18.

The lower guide 16 is for fixing the lower end portion of the guide suspension wire 14 at a predetermined height position, and is provided several floors below the overhang bracket 12 (four floors below in the example of FIG. 2). As the lower guide 16, for example, the guide of the gondola rail of the exterior material 2 already attached can be used. In this case, the lower end of the guide suspension wire 14 may be inserted into the guide to fix it laterally.

The mesh sheet 18 is a mesh-shaped rectangular curing sheet configured to be small and can be stored, and has wind resistance or wind resistance. The upper end of the mesh sheet 18 is attached to a fixing member 30 made of H-shaped steel. The fixing member 30 is engaged with the hook 22 of the winding mechanism 20. Therefore, the mesh sheet 18 is fixed to the overhang bracket 12 via the fixing member 30, the hook 22, and the winding mechanism 20.

Pleats (creases) (not shown) are formed on the mesh sheet 18 at equal intervals in the vertical direction. Therefore, as shown in FIG. 4, the mesh sheet 18 can be folded in a zigzag shape in the vertical direction in a side view. Further, connecting rings 24 are attached to the mesh sheet 18 at equal intervals in the vertical direction. A guide suspension wire 14 is passed through the connecting ring 24. Therefore, the mesh sheet 18 is attached to the guide suspension wire 14 so as to be movable in the vertical direction.

It is desirable to use a mesh sheet 18 that can reduce the wind speed by, for example, about 50%. In this way, the exterior material 2 can be attached without lowering the work efficiency even when the wind blows. In addition, the safety of workers can be ensured. By covering the entire circumference of the mounting area with the mesh sheet 18, it is possible to avoid the risk of scattering and wind scattering. In addition, it is possible to give a sense of security to the outside.

In the example of FIG. 2, the size of the mesh sheet 18 is configured as one sheet having four spans in the left-right direction and four floors in the height direction. Of these, the lower two floors are assumed to be the mounting floors for the exterior material 2, but the present invention is not limited to this. Each mesh sheet 18 may be opened and closed independently and independently by the winding mechanism 20 described later.

The take-up mechanism 20 is for raising and lowering the mesh sheet 18 up and down along the guide suspension wire 14, and includes a hook 22 connected to the lower end of the take-up wire. As described above, the fixing member 30 of the mesh sheet 18 is engaged with the hook 22. The take-up mechanism 20 can be configured by, for example, an electric take-up mechanism.

The operation and operation of the above configuration will be described.
As shown in FIG. 4, when the winding mechanism 20 is driven to lower the hook 22, the fixing member 30 is lowered, and the mesh sheet 18 is folded and deformed and lowered along the guide suspension wire 14. By doing so, the mesh sheet 18 can be opened. At this time, since the mesh sheet 18 is folded and contracts downward, it can be easily collected and removed.

Further, when the winding mechanism 20 is driven to raise the hook 22, the fixing member 30 is raised, and the mesh sheet 18 is raised along the guide suspension wire 14 while unfolding. By doing so, the mesh sheet 18 can be closed. In this way, the mesh sheet 18 can be easily installed.

According to this embodiment, the mesh sheet 18 can be easily removed and installed in the exterior work of the high-rise office building 1. Further, by stretching the mesh sheet 18 around the mounting area of the exterior material 2, it is possible to prevent the intrusion of wind into the mounting area and reduce the wind pressure received when the exterior material 2 is lifted and mounted. By reducing the influence of wind, the workable time and the number of workable days can be increased, and the overall walk-through can be improved. Further, since the influence of the wind is reduced, the choices of the construction method can be increased, such as making the unit panel of the exterior material 2 large or making a set of two. Further, when a storm is expected such as during a typhoon, it is necessary to roll the mesh sheet 18. This embodiment is effective when it has to be done frequently because it can be done easily. It can also serve as a measure to prevent wind scattering.

Further, as shown in FIG. 2, the curing device 10 may be arranged independently for a plurality of mounting areas and may be opened and closed independently, or may be independently replaced on the upper floor. May be carried out with a tower crane or the like. For example, the curing device 10 may be climbed every time the installation work for two floors is completed. In that case, the overhanging bracket 12 is released from the floor slab 4, and the lower guide 16 is pulled up as it is along the gondola rail, for example, so that the refilling work can be performed.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described.
As shown in FIG. 5, the curing device according to the second embodiment can move the mesh sheet 18 in the left-right direction instead of moving the mesh sheet 18 in the vertical direction in the curing device 10 of the first embodiment. It is configured.

In the mesh sheet 18, pleats (creases) (not shown) are formed at equal intervals in the left-right direction. Therefore, the mesh sheet 18 can be folded in a zigzag shape in the left-right direction in a plan view. Connecting rings (not shown) are provided at equal intervals in the left-right direction at the upper and lower ends of the mesh sheet 18. The mesh sheet 18 is movably attached to the upper and lower curtain rails 32 in the left-right direction via the connecting ring. The upper curtain rail 32 is fixed to the tip of the overhang bracket 12. The lower curtain rail 32 is fixed to the guide 16A of the gondola rail.

A winding mechanism (not shown) is fixed to the left end or the right end of the mesh sheet 18. By driving this winding mechanism and moving the mesh sheet 18 in the left-right direction along the curtain rail 32, the mesh sheet 18 can be opened and closed. Even in this way, the same effect as that of the first embodiment can be obtained.

In the above embodiment, the case where the mesh sheet 18 which is a curing sheet can be folded in a zigzag shape in the vertical direction or the horizontal direction has been described as an example, but the curing sheet of the present invention is not limited to this. Anything may be used as long as it is configured to be small in the vertical direction or the horizontal direction so that it can be stored. Even in this way, the same effects as described above can be obtained.

As described above, according to the curing device according to the present invention, it is a curing device for curing the outer peripheral portion of the building, and the support material protruding outward from the building frame and the suspension suspended from the support material. A material and a fixing material that fixes the lower part of the hanging material at a predetermined height position, and can be attached to the hanging material so as to be movable in the vertical or horizontal direction, and can be stored in a smaller size in the vertical or horizontal direction. Since it is provided with a curing sheet configured to be In addition, it can be easily installed by unfolding the curing sheet. Therefore, the curing sheet can be easily removed and installed in the exterior work of a high-rise office building or the like.
