Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building frame construction apparatus for constructing and bridging structural members such as columns and beams, attaching curtain walls and finishing interior work.

[0002]

2. Description of the Related Art Generally, a method of assembling a structural member such as a pillar or a beam made of a steel frame material or a structural member such as a pillar or a beam made of a PC material on site to construct a frame is generally shown in FIG.
As shown in Fig. 4, a lifting machine is installed on the outer periphery of the building or on a beam or slab that has already been built, and structural members such as columns and beams are hung by this lifting machine and installed at the installation position to build a frame structure. Met.

[0003]

However, in such a method, an arm hoisting tower crane, an arm horizontal tower crane, or the like is used as a hoist, and a large crane having a large hoisting radius is used. By doing so, the work is considered to be performed with the least amount of heavy equipment. For this reason, the crane becomes large in size and heavy in weight. Therefore, it is necessary to sufficiently reinforce the frame by supporting the crane by supporting the crane, and there is a problem that the cost is inevitable.

Further, since a scaffold cannot be attached to a structural member such as a pillar or a beam until the assembly of the structural member is completed, the assembling work of the structural member is forced without a scaffold, which is directly performed by an operator. This resulted in extremely dangerous work such as climbing a pillar or walking on a beam, which caused not only a safety problem but also a serious shortage of workers.

Therefore, in order to solve the problems of the conventional method, the applicant constructs a frame structure of a building by assembling on-site a steel frame member or a PC member which is manufactured in advance as a structural member such as a pillar or a beam. We have developed a construction method for a building frame and have already filed an application.

[0006] However, the conventional invention uses a work trolley configured so as to be movable in the upper floor direction by using the already constructed frame as a receiving portion, and prefabricated members are assembled on site to construct a steel frame structure or a steel frame structure. Although it is a method of constructing a frame made of PC, it is not specifically configured to be movable laterally,
The work range per machine was naturally limited, and interior finishing work could not be performed, so work efficiency was not always good.

[0007] Therefore, as the scale of the building becomes larger, it is necessary to use many work benches, and there are problems such as the work of assembling and dismantling and removing after construction is difficult.

The present invention has been made in order to solve the above problems, and can be moved in the horizontal and vertical directions in parallel with the progress of construction, and in particular, the structure of a building can be efficiently constructed. It is an object of the present invention to provide a frame construction device for a building.
