Description

[Detailed description of the invention] [Industrial application field] This invention is a curing device for gondolas used to prevent materials and chips from falling and scattering when working on walls of structures such as buildings. It is related to.

[Conventional technology]

For renovation work and new construction work on buildings and other structures,
A gondola is hung from the roof of a building, and workers riding in the gondola sometimes perform various types of work on the exterior walls.

Work on exterior walls like this often generates chips, etc., and dropping them from a high-place gondola or scattering them poses a danger to workers and structures on the ground. The impact is also large, such as causing accidents and contaminating the surrounding environment.

Furthermore, if materials used for work are accidentally dropped, it is even more dangerous because they are larger and heavier than chips or the like.

[Problem that the invention attempts to solve]

In order to prevent the dangers caused by falling and scattering materials and chips, the entire outer wall of the building is covered with sheets or nets, and devices developed to facilitate entry and exit into the building, i.e. the second floor area. A continuous curing platform with a self-climbing device is installed at the top of the building, and a device is used to cover the roof with curing nets.

However, all of the above methods involve covering the entire or most part of the outer wall, requiring a long time to temporarily install and remove protective nets, etc., and are expensive and uneconomical.

In particular, it becomes even more uneconomical when the structure becomes larger and taller.

This idea was made in view of the prior art, and it is not necessary to cover the entire structure such as a building, and the gondola part alone can prevent falling and scattering, and even if the gondola shakes, no gaps are formed. The present invention aims to provide a gondola curing device that is automatically adjusted as described above.

[Means for solving problems]

In order to solve the above problems, this idea makes it possible to rotate the proximal end of the bottom curing member, which closes the gap between the gondola and the structure by bringing its tip into contact with the surface facing the structure of the gondola suspended from the structure. A balancer is installed on both sides of the gondola to apply a force that almost balances its own weight to the bottom curing member to smooth the rotation in response to changes in the gap between the structure and the gondola. The invention is characterized in that the side curing members that close the bottom curing members are respectively attached so as to be reciprocally movable, and a connecting mechanism is provided for reciprocating the side curing members in conjunction with the rotation of the bottom curing member.

[Effect]

The proximal end of the bottom curing member is rotatably attached to the face of the gondola facing the structure, the tip thereof is brought into contact with the wall of the structure, and a force approximately balanced with its own weight is applied to the bottom curing member. Even if the gap with the structure changes, this gap can be automatically closed by utilizing the change in the resistance force applied from the wall surface to the tip of the bottom curing member. Furthermore, the side curing members are attached to both sides of the gondola so as to be reciprocally movable, and are connected to the bottom curing member by a connecting mechanism to allow the side curing members to reciprocate in conjunction with the rotation of the bottom curing member. The gap between both sides of the structure and the structure is automatically closed.

〔Example〕

An embodiment of this invention will be described below in detail with reference to the drawings.

Figures 1 to 3 show an embodiment of the gondola curing device of this invention; Figure 1 is a front view, and Figure 2 is a front view;
The figure is a partial plan view, and FIG. 3 is a left side view.

Gondola 10 suspended from the roof of a structure, etc.
The gondola 10 is mounted on the back side of the cage section 11 on which the workpiece is boarded (with respect to the wall surface of the structure which is the work surface).
A back curing frame 13 on which a wider fixed curing net 12 is stretched is installed, and side fixed curing frames 14 having the same width as the gondola 10 are installed on both sides, and the curing net 12 is stretched on the back side curing frame 13. There is.

Inside these side fixed curing frames 14, side movable curing frames 15 as side curing members are arranged, and curing nets 12 are stretched. Rip groove type steel guide rails 16 are attached to the top and bottom of the
As shown in an enlarged view in FIG. 3, a plurality of guide rollers 17 attached to the side movable curing frame 15 fit inside and roll.

Therefore, by moving these side movable curing frames 15 forward to close the gap between the structure and the gondola 10, the gondola 10 is prevented from scattering to the side. Note that a cushion material 18 such as rubber is attached to the surface of the side movable curing frame 15 that comes into contact with the structure, and has a cushioning effect.

Next, a bottom curing frame 19 is arranged as a bottom curing member to close the gap between the front surface of the gondola 10 and the structure, and the end on the gondola 10 side is hinged at two places.
It is connected at 0 and can be rotated, and is covered with a transparent vinyl sheet 21 and cushion rollers 22 are attached to two places at the tip to reduce contact resistance with the structure. . Further, a rubber plate 23 is attached to the tip edge of the bottom curing frame 19 so as to be in close contact with the surface of the structure.

Therefore, if the bottom curing frame 19 is placed against the surface of the structure while being tilted at an acute angle from the gondola 10, the gap between the bottom curing frame 19 and the gondola will be closed, preventing the gondola 10 from falling downward or being scattered. When the bottom curing frame 19 approaches or moves away due to shaking, the inclination angle of the bottom curing frame 19 changes to keep the gap closed at all times. The bottom curing frame 19 tries to rotate horizontally due to its own weight, reducing the angle of inclination and making it difficult to approach the gondola 10. Therefore, a spring balancer 24 is attached to the gondola 10, which pulls the bottom curing frame 19 with a tension that almost balances its own weight. , a wire 25 is connected to the tip of the bottom curing frame 19. The spring balancer 24 is formed of, for example, a spiral spring, and acts to draw in the wire 25 with a constant force.

On the other hand, connecting rollers 27 are provided on both sides of the tip of the bottom curing frame 19 as a coupling mechanism 26 that interlocks the bottom curing frame 19 and the side movable curing frames 15 on both sides and automatically closes the gap between the gondola 10 and the structure. As shown in the enlarged view in FIG. 3, the connecting roller 27 rolls along a lip groove type steel connecting guide rail 28 attached to the inside of the tip of the side movable curing frame 15. It's getting old. Furthermore, in order to ensure smooth interlocking, the base end of the rotating link 29, which forms a parallelogram link with the frames at both ends of the bottom curing frame 19, is attached to the gondola 10 with a hinge 30, and attached to the support shaft at the tip. An upper connecting roller 31 is attached, and this upper connecting roller 31 also rolls within the connecting guide rail 28.

Therefore, when the gondola 10 tries to move away from the structure, the bottom curing frame 19 tends to tilt horizontally, and the connecting roller 27 and the upper connecting roller 31 move along with the connecting guide rail 28 to the side movable curing frame. 15 to the front so that there is no gap between the gondola 10 and the structure on the front side and both sides. Conversely, when the gondola 10 attempts to approach a structure, the bottom curing frame 19 receives a force to reduce the inclination via the cushion roller 22 at its tip, and this force is applied to the connecting roller 27 and the upper part. The signal is transmitted from the connecting roller 31 to the connecting guide rail 28, and the side movable curing frame 15 is moved backward, so that even in this state, there is no gap between the gondola 10 and the structure on the front side and both sides.

In the above embodiment, the gaps between the bottom and both sides of the gondola and the structure are closed, but the upper part of the side fixed curing frame is closed with the upper fixed curing frame, and the upper part of the side movable curing frame is closed with the upper fixed curing frame. Connecting and blocking with a curing frame is effective in preventing chips etc. from scattering upward and blowing up.

Further, by diagonally cutting the upper and lower front ends of the side movable curing frame, even if there are protrusions on the structure when the gondola moves up and down, it can smoothly overcome these.

Furthermore, in this specification, the term gondola is not limited to self-propelled ones, but has a broad concept that includes externally driven ones.

[Effect of idea]

As specifically explained above in conjunction with the embodiments, according to this invention, the proximal end of the bottom curing member is rotatably attached to the surface of the gondola suspended from the structure facing the structure. In addition to closing the gap at the bottom, side curing members are attached to both sides of the gondola so that they can move back and forth to close the gap between the sides with the structure, and these are connected by a connecting mechanism. Therefore, it is possible to prevent scattering and falling only at the gondola part, and the curing device can be installed in a short time, and the cost can be significantly reduced, making it economical.

Furthermore, the proximal end of the bottom curing member is rotatably attached to the surface of the gondola facing the structure, and its tip is brought into contact with the structure wall surface, giving the bottom curing member a force that is approximately balanced with its own weight. Even if the gap between the gondola and the structure changes, this gap can be smoothly and automatically closed by utilizing changes in the drag force applied from the wall to the tip of the bottom curing member. It is easy to handle and does not require any special operations from within.

Further, even if the gap between the gondola and the structure changes due to the shaking of the gondola, etc., the rotation and reciprocation of the bottom curing member and the side curing member always maintain a closed state, thereby preventing falling and scattering.
