Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a scaffolding device for performing a series of exterior works such as mounting and sealing aluminum panels, curtain walls, glass sashes, etc. of super high-rise buildings. Regarding

[Prior Art] Currently, there is no domestic construction example of a structure in which all columns of a high-rise building project outward from the outer wall and the exterior is finished with aluminum panels.

In overseas construction examples, a normal gondola with a wire rope as a steady guide is used as a scaffold in the possible range, a fixed type scaffold is installed in the impossible range, and a normal super high-rise building is used as a lifting facility. The method is to install many tower cranes.

[Problems to be Solved by the Invention] The above system has the following problems.

(1) When mounting a vertically long exterior material, it is difficult for a normal gondola to perform simultaneous work on the upper end and the lower end.

(2) With a wire rope type guide, it is difficult to work because the gondola rolls significantly.

(3) It is unreasonable to install a large number of fixed scaffolds to cover the entire surface of a building as auxiliary scaffolds, because it is difficult to relocate the scaffolds upward, and safety, cost, construction period, etc. is there.

(4) Lifting a large number of exterior materials with a tower crane requires a long cycle time, which requires a long construction period, and the number of tower cranes installed is limited.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a scaffolding device capable of simultaneously operating upper and lower parts of a vertically long exterior material, having no rolling, and not requiring a fixed auxiliary scaffold and a tower crane.

[Means for Solving the Problems] A scaffolding device according to the present invention comprises a gondola that can be raised and lowered along a pair of guide rails that are erected opposite to each other via a lateral shake prevention member, and is self-propelled on the scaffolding of the gondola. In addition, it is provided with an upper scaffold that can be lifted and lowered, a hoisting machine installed on the upper scaffold, and auxiliary scaffolds that can be deployed around the scaffold of the gondola and the upper scaffold, respectively.

It is preferable that the guide rails are detachably fixed to both ends of a support table provided on a flat brace of a steel column of a building.

Further, it is preferable that the roll-sway preventing member is constituted by a guide plate having one side fixed to the suspension frame of the gondola and the other side contacting the inner surface of the guide rail, and the guide plate is provided with a pin hole fixed to the guide rail. .

Further, it is preferable that the hoist comprises a hydraulic crane with an auxiliary jib capable of half rotation.

[Operation] In the scaffolding device configured as described above, the gondola is lifted and the guide plate is pin-fixed to the guide rail to fix the guide plate at a predetermined position. Therefore, the exterior material is lifted from the floor with a hydraulic crane, moved to a predetermined position, and attached using the scaffolding and the auxiliary scaffolding.

At this time, each scaffolding and auxiliary scaffolding allow a wide vertical work, and the upper and lower parts of the exterior material can be simultaneously worked.

In addition, the guide plate can prevent horizontal and vertical shaking of the entire gondola, and the reaction force of the gondola during work can be received by the guide rails to reduce the power for raising and lowering the gondola.

Further, by providing the auxiliary stage, it is not necessary to provide another fixed auxiliary scaffold, and the scaffold can be provided at a necessary place regardless of the presence or absence of an obstacle.

In addition, the hydraulic crane allows the exterior material to be hung from the floor side, and the gondola has a lifting function so that quick work can be performed.
