[Problems to be Solved by the Invention] However, as described above, there is no method in which a curtain wall or the like made of precast concrete having a surface finish of metal panels or tiles is hung by a lifting machine or the like and attached at a predetermined position. The scaffolding method and the external scaffolding are temporarily installed to perform the mounting work, but the above-mentioned method has the following problems.

In the mounting work by the scaffolding method, since a single panel or curtain wall member made of metal is hoisted and mounted, the mounting work is repeated as many as the single unit, and the mounting work is complicated and the members are Since it is performed in an unstable posture when it is taken in from the building, there are many risks when working in high places, but it is difficult to secure personnel because there are no safety measures and skilled workers are required for the work. .

Further, when an external scaffold is temporarily installed on the entire outer periphery of the building, the members are hung between the external scaffold and the building and transported to the mounting position, so that a panel having a very large shape cannot be formed, so that work efficiency is improved. Does not rise. Furthermore, a great deal of labor is required to assemble and disassemble the scaffold.

Commonly, in a method in which a metal panel or curtain wall member is hoisted by a lifting machine or the like and conveyed to a predetermined position, the process is delayed because the member cannot be unloaded and taken in mainly in strong wind because of the weather. In addition, joint caulking between members after mounting the members is inefficient due to work at high places, and uniform quality control is difficult.

The present proposal is proposed in view of the problems of the above-mentioned prior art, and its purpose is to use a scaffold-free construction method as a basis and to make a large-sized unit with a metal panel or curtain wall member. In addition to improving the efficiency of installation work, one side of the building is assembled on the ground part on a platform that can be raised and lowered by lifting means, and the platform is moved and transported to a predetermined position and installed from inside the building. , Provides a construction method for mounting exterior panels of buildings that can save labor and ensure safety.

[0007]

In order to achieve the above-mentioned object, the building exterior panel mounting construction method of the present invention comprises a pedestal installed on the ground which is vertically movable along one side of the building by the elevating means. A plurality of large-scale exterior unit panels prepared in advance on a gantry are placed on a desired size on one side surface of the building to seal between the exterior unit panels, and the gantry and the exterior unit panel are placed at the bottom. Tightly connected,
The upper parts of these exterior unit panels are connected together to be assembled integrally, and they are raised to a predetermined position on the upper part of the building by the elevating means, and are tightly connected to the building body, and the tightness between the pedestal and the lower part of the exterior unit panel is released. Then, the elevator unit descends and restores to the ground, and the next lower floor is also constructed by sequentially attaching the exterior unit panel to one side surface of the building by repeating the above work.

Further, when mounting the exterior panel by the above-mentioned construction method using the pedestal, while controlling the control device based on the measurement data of the measuring device for measuring the horizontal and vertical states of the pedestal, the upper part of the building is controlled. Attach the exterior unit panel that has been raised to the specified position to the regular position on the building side.

[0009]

[Operation] A pedestal that can be raised and lowered along one side of the building by the elevating means is installed on the ground, and a plurality of large exterior unit panels pre-fabricated on the pedestal are mounted on the one side of the building in a desired size. The exterior unit panels are sealed together, the base and the exterior unit panels are tightly connected at the bottom, the tops of the exterior unit panels are connected together, and they are integrally assembled, and the platform is installed by the elevating means.

However, the planar shape of the one side surface of the building is not limited to this example, and the planar shape is not limited to this example. It can also be applied to arcuate and wavy shapes. That is, any shape can be applied as long as there is no protrusion in the middle of the building 1 and the like and the planar shape is maintained vertically.

Although the exterior panel may be attached to the other side surface of the building by the above-described construction method, the construction method of the present invention may be applied to the case where the exterior panel is attached to only one side surface depending on the location of the building or the like. This is effective when the exterior panel is attached to one side where this construction method can be implemented when this construction method cannot be implemented due to the special shape of the side surface.

Further, in this example, the chain block 3 is used as the elevating means for elevating the elevating stand 2.
The elevating means is not limited to the chain block 3, but may be a hoist mechanism or the like.
