Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting an exterior curtain wall composed of a metal panel system, an aluminum curtain wall system or the like.

[0002]

2. Description of the Related Art Conventionally, an exterior wall of a building is composed of a metal panel system, a precast concrete system and an aluminum curtain wall system, and a panelized curtain wall is used as the exterior wall. These exterior curtain walls are not built on-site, but are manufactured in advance as an exterior curtain wall panel unit at the factory, transported to the site according to the progress of the construction site, and installed according to the building structure of the building. ing.

The method of mounting the exterior curtain wall panel unit is to use the lifting means (crane) installed on the roof of the building or the like to directly mount the exterior curtain wall panel unit one unit from the ground or on the truck. It is common to hang them up and attach them sequentially from the bottom. Further, there is already a method of attaching Japanese Patent Application No. 5-204056 proposed by the present applicant.

According to this construction method, an exterior curtain wall assembly work facility is installed on the ground portion of the exterior wall surface of the building to which the exterior curtain wall is attached, and along the assembly work facility, the width is the same as the width of the exterior wall surface, or the elevator curtain is moved up and down. The pedestal is divided so as to correspond to the uneven outer wall surface, and the elevating pedestal is sequentially attached downward from the upper part of the building outer wall surface by the elevating means provided on the outer wall surface of the building.

[0005]

According to the above-mentioned conventional generally used mounting method, since each of the exterior curtain wall panel units is individually lifted and mounted, the number of panel units is repeated. Since the installation work is complicated, the work is complicated, and during that time, the crane becomes a factor that interrupts other building work and delays the process.

[0006] The latter is the installation enforcement method of Japanese Patent Application No. 5-204056 proposed by the present applicant, in which the exterior curtain wall assembly work facility is installed on the ground part of the outer wall surface of the building, Since a platform having the same width as the width of the outer wall of the building is erected and a plurality of hoisting means (electric chain blocks) are operated to hoist at the same time to raise and lower, a hoisting stand due to an error in hoisting speed of the plurality of hoisting means. Caused a rough surface,
Since it is difficult to deform the exterior curtain wall assembled on the gantry and attach it to a predetermined position, the gantry cannot be made too long (width of the outer wall surface of the building).

Further, when the head is high, the exterior curtain wall sways greatly due to the wind pressure during strong wind, and the work must be stopped. The present invention was developed to address such problems, and it is an object of the present invention to provide a safe enforcement method adapted to a large-scale building to improve work efficiency and save labor.

[0008]

In order to achieve the above-mentioned object, the structure of the present invention is to install a connecting elevating platform which is connected to elevating means and is capable of following displacement, in an assembling work facility for an outer wall of a building and at the same assembling work facility. An exterior curtain wall material transfer device is installed on a floor in the vicinity of, and the curtain wall member is transferred from the exterior curtain wall material transfer device onto the connecting elevating platform, and the exterior curtain wall of the first floor of the building is installed on the connecting elevating platform. The assembled exterior curtain wall is raised to a predetermined position on the upper part of the building by the rise of the connecting lifting platform, and the exterior curtain wall that has been raised to the predetermined position is tightly bound to the outer wall surface of the building and tightly bound to the outer wall surface of the building. The exterior curtain wall that has been removed is released from the connecting lifting platform, the connecting lifting platform is restored to the assembly work facility, and the work is repeated. And wherein the Succoth.

Further, the lifting and lowering of the connection lifting / lowering platform is performed by automatically controlling the winding speed integrally by a plurality of lifting / lowering means. Further, the winding speed is automatically controlled via an inverter provided in the circuit.

[0010]

The exterior curtain wall of one floor of the building is assembled on the followable connecting elevator frame installed in the assembling work facility by the above means, and the assembled exterior curtain wall follows the elevator platform that can follow. It can be safely lifted up to a predetermined position along the floor of the building and tightly fixed to the main body of the building, and the exterior curtain wall after tightly fixed to the main body of the building is cut off from the connecting lifting platform and the connecting lifting platform is assembled. The exterior curtain wall can be attached by reconstructing it on the work facility and again assembling the exterior curtain wall of one floor of the building on the connecting elevator platform on the assembly facility and repeating the same operation as described above.

Further, since the raising and lowering of the connecting elevating and lowering platform is automatically controlled by a plurality of elevating means, the winding speed is automatically controlled integrally, so that the exterior curtain wall assembled on the connecting elevating and lowering platform can be smoothly raised and lowered without being deformed. Further, since the winding speed is automatically controlled through the inverter provided in the circuit, the winding speed can be freely changed to low, medium, or high speed to facilitate control.
