Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for assembling a metal panel system, a precast concrete system, or an aluminum curtain wall system exterior curtain wall in a building.

[0002]

2. Description of the Related Art Conventionally, the exterior walls of buildings are structurally non-bearing walls, such as metal panel systems, precast concrete systems,
A curtain wall composed of aluminum curtain wall type wall material is used. These curtain walls are manufactured in a factory in advance, brought into the construction site according to the progress of the construction site, and attached to the skeleton in accordance with the construction of the building skeleton.

The curtain wall is hoisted directly from the ground or on a truck by using a hoisting means such as a crane installed on the roof, and is sequentially mounted from the bottom. In the case of aluminum-based curtain walls, the curtain wall frame and glass are once placed on each floor of the building, glass is put in on the mounting floor and the seal material is loaded to assemble, and it is mounted by lifting means from the upper floor of the mounting floor. ing.

Such a curtain wall construction method has come to be more and more actively carried out together with the non-scaffolding construction method, as the building becomes higher in height.

[0005]

However, the above-mentioned method of mounting the curtain wall adopts the non-scaffolding construction method and uses a crane or the like installed on the roof to directly lift it from the ground or from the top of the truck to lower it. However, the above method has the following problems.

That is, although the curtain wall attached to the exterior of the building is manufactured in advance as a large unit panel at the factory, the size of the curtain wall unit is limited because it is transported to the site according to the progress of the construction site. Since it is taken up as a panel on the site and mounted as a single unit of the curtain wall unit panel, it is necessary to repeat the installation work as many times as the number of curtain wall unit panels, which complicates the work, during which other erection work using a crane is performed. Will be interrupted, causing delays in construction.

Further, as described above, the curtain wall unit panel is transported from the ground or from the track to a predetermined mounting position by the crane or the like installed on the roof, and the panel is taken in by the worker from inside the building. Therefore, the work posture becomes unstable, and there are many dangers when working in high places, and safety measures such as protective fences and safety ropes are taken, but it is difficult to secure personnel because skilled workers are required. Become.

Furthermore, since the curtain wall member is hoisted from the ground by a lifting machine or the like and conveyed to a predetermined mounting position, the work depends on the weather, and particularly when the wind is strong, the hoisting of the curtain wall unit panel becomes unstable, and the work is It will have to be canceled and it will cause a delay in construction. Also, a lot of work such as joint sealing between members after attaching the curtain wall unit panel is left, and since these works are performed at high places, work efficiency is reduced,
Quality control becomes difficult.

The present invention has been proposed in view of the problems of the above-mentioned prior art, and its purpose is to improve the workability, ensure the accuracy of attaching the curtain wall, save labor and improve safety. It is an object of the present invention to provide an exterior curtain wall assembling apparatus for a building, which is improved.

After that, it is input to the operating device U, and the operating device U controls the lifting / lowering of the lifting / lowering platform D. The height sensor T and the controller R control the horizontal inclination value and control height of the lifting / lowering platform D. Monitoring is performed, and when the initial set value is exceeded, an alarm is issued and automatic stop is performed for safety, while the operating device U manually operates a switch within a range of the initial set value to operate at a predetermined position.

K is a PC steel rod, which is tensioned between the fastening end 3 and the upper fixed end 4 below the outer wall. FIG. 5 shows a portion through which the PC steel rod K is inserted into the lifting platform D, and 5 is a bearing portion through which the PC steel rod K is inserted. When assembling the curtain wall B, the curtain wall members are supplied to the curtain wall assembling work facility C, the curtain wall B is assembled on the lifting platform D, and the curtain wall C is assembled by the electric hoist P for each work section.
Is lifted to a predetermined position for mounting, and when the mounting work is completed, the hoisting machine P and the curtain wall B are separated, the lifting platform D is returned to the original position, and the same operation is repeated for the next floor. The curtain wall B in sequence. In FIG. 1, D ₁ shows the state of the elevating platform which is descending after the curtain wall is attached, and D ₂ shows the state where the curtain wall B is being conveyed to the upper floor.

Next, details of this apparatus will be described. In the curtain wall assembling work facility C, a pedestal 6 having a high floor is constructed, and a scaffold 7 for assembling the curtain wall is erected on the pedestal 6, and the top of the scaffold 7 in the longitudinal direction is jumped out of the scaffold to form a trolley device 8. , An opening 9 for supplying materials to the floor of a gantry 6 provided on a high floor, and a hoisting work vehicle 1 for lifting on the ground
