DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gondola-type temporary scaffold suspended along a wall of an existing building and mainly used as a hanging scaffold for repairing, reinforcing, or cleaning the wall of the existing building.

[0002]

2. Description of the Related Art Conventionally, as a simple temporary scaffold used to repair or reinforce the wall of an existing building, a gondola is hung at the tip of a telescopic boom of a crane truck installed on the ground, and the boom is expanded and contracted. It is generally known that the gondola can be moved freely.

[0003]

However, this type of temporary scaffold naturally has a limit on the length of the boom,
Its use is limited to low-rise buildings, and it cannot be used for middle- and high-rise buildings at all.

The present invention has been made to solve the above problems, and provides a gondola-type temporary scaffold having an extremely simple structure and usable not only for low-rise buildings but also for middle-high-rise buildings. The purpose is to:

[0005]

In order to solve the above problems, a gondola type temporary scaffold according to the present invention is provided with a work gondola suspended along the wall of an existing building and a movable gondola on the roof of the existing building. A movable trolley installed on the movable trolley, the movable trolley includes a suspending arm extending and extending outside the wall surface of the existing building, and a suspending arm suspending the work gondola via a suspending wire. A plurality of buffering jigs projecting toward the wall surface of the existing building and running vertically and horizontally on the wall surface of the existing building.

Further, an auxiliary floor which is slid horizontally and protrudes toward the existing building and which is slid horizontally and is accommodated in the work gondola is attached to the work gondola, and a handrail is attached to the auxiliary floor. ing.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 of the Invention 1 to 3 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a work gondola vertically suspended along a wall surface of an existing building A, and 2 denotes a work gondola installed on the roof of the existing building A. This is a movable cart that suspends the work gondola 1 along the wall surface of the existing building A via the suspension wire 3.

In the working gondola 1, a plurality of vertical frames 4 and horizontal frames 5 made of a shape member such as lightweight steel are connected to each other, and a floor is installed. It has a rectangular parallelepiped box that can accommodate one or several workers. Note that the vertical frame 4
The components such as the horizontal frame 5 and the like are all assembled with, for example, connecting bolts so that they can be easily assembled and disassembled.

The work gondola 1 is equipped with a winch 6 for winding and releasing the suspension wire 3 to move the work gondola 1 up and down along the wall of the existing building A. By projecting and abutting the wall, the distance between the work gondola 1 and the existing building A is kept constant, and the work gondola 1 is prevented from accidentally colliding violently with the wall. A plurality of buffer jigs 7 are provided so that the work gondola 1 can freely move by freely traveling in the lateral direction.

The buffer jig 7 has a horizontal arm 8 mounted on the horizontal frame 5 so as to be able to freely adjust a protruding length L (see FIG. 2A) to the existing building A side, The arm 8 includes a plurality of buffer rollers 9 which are vertically adjacent to each other and are rotatably mounted on a horizontal axis.

The horizontal arm 8 is provided on the horizontal frame 5 with a plurality of mounting bolts 10 which selectively pass through a plurality of bolt holes 5a (see FIG. 3A) formed at predetermined intervals in the horizontal frame 5. It is attached so that the length of protrusion L to the existing building A side can be freely adjusted by bolting. At this time, the mounting bolt 10 is inserted into the bolt hole 8a of the horizontal arm 8. The buffer roller 9 is formed from a rubber tire or the like.

The movable trolley 2 is provided with a suspension arm 11 that extends horizontally from the roof of the existing building A so as to extend outside the wall surface so as to be able to extend and contract horizontally, and can be moved by power on a rail 12 laid on the roof of the existing building A. It is installed in. Hanging arm
Numeral 11 is configured to be freely expandable / contractible by, for example, a hydraulic cylinder or the like.

In such a configuration, while the worker stays in the work gondola 1, the winch 6, the suspension arm 11, and the movable trolley 2 are remotely controlled, so that the work gondola 1 is slid along the wall of the existing building A. Can be moved freely in the vertical and horizontal directions.

Embodiment 2 of the Invention FIGS. 4 (a), 4 (b) and 5 (a), 5 (b) show another embodiment of the present invention, in which the building 1 is slid horizontally on the floor 1a of the working gondola 1 to the side of the existing building A. An auxiliary floor 1b which is protruded and slides horizontally and is stored in the floor 1a of the work gondola 1 is attached, and a handrail 1c is attached to the auxiliary floor 1b. Also,
At an end of the auxiliary floor 1b, a buffer roller 9 that runs on the wall of the existing building A is attached. Other configurations are exactly the same as those of the first embodiment.

According to the embodiment of the present invention, the work gondola 1 needs to be separated from the wall of the existing building A to some extent, for example, in order to install the seismic retrofitting construction B along the wall outside the existing building A. In some cases, it can be used as a gondola type temporary scaffold.
It is possible to work safely by increasing the floor area of the building and making the working scaffold closer to the existing building.

Embodiment 3 of the Invention FIGS. 6 (a) and 6 (b) show another embodiment of the present invention, in which a hanging arm 11 is fixed to a parapet (rise wall) C formed on the roof of an existing building A, and thus a work arm is provided. The gondola 1 is suspended, and the other configuration is almost the same as that of the first embodiment.

[0017]

According to the present invention, a gondola-type hanging scaffold is provided.
In particular, since the working gondola is suspended from the roof via a hanging wire on the side wall of the existing building, it has an effect that it can be used for repairing and cleaning the wall of a middle- and high-rise building.

Further, by projecting the work gondola on the wall surface side of the existing building and abutting against the wall surface of the existing building, the distance between the work gondola and the existing building is kept constant, and the work gondola is kept constant. Since multiple bumping jigs running vertically and laterally on the wall of the
Repair and cleaning of the wall can be performed by freely moving the wall of the existing building.
