Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Korean Patent Application No. 10-2016-0089604, filed on Jul. 15, 2016 in the Korean Intellectual Property Office, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a cage apparatus for construction, and more particularly, to a structure for connecting a cage for construction with a gondola for exterior finish work in order to carry out frame work and exterior finish work to be stacked up.

Background Art

In general, finishing work for an outer wall of a high-rise building is carried out on a gondola when support beams are mounted on a rooftop and the gondola is hung up after frame work is completed. Because such exterior finish work before frame work is finished cannot be started, there is a process gap between the two works, and it may cause an increase of the entire construction period of time.

Therefore, in some of construction sites in Korea, in order to carry out frame work and exterior finish work at the same time, a method of adding a work plate of one step or two steps below a cage for construction or a method of additionally installing a cage for finishing work of an outer wall below a cage for frame work is adopted.

However, the method of adding the lower work plate has a limitation in adding the number of steps of work plates due to an increase of cage load and an increase of construction costs. Moreover, the method of adding the lower work plate has additional disadvantage in that frame work may be delayed and the entire construction period of time is increased because it is impossible to raise the cage to an upper layer if the construction-per-layer periods of frame work and exterior finish work are not synchronized.

The method of additionally installing a cage requires a lot of time to install and dismantle the additional cage and causes an increase of construction costs. Particularly, the two methods to carry out construction work by the unit of a layer may cause waste of productivity and an increase of construction costs because workers for exterior finish work can secure just a work amount of one layer during the construction period per layer. Therefore, technology for minimizing additional costs, allowing the workers for exterior finish work to secure a sufficient work amount, and supporting concurrent construction of frame work and exterior finish work is required.

SUMMARY OF THE INVENTION
