Abstract

PURPOSE:To enhance the workability by assembling an external curtain wall on a plurality of elevation beds coupled together, and by conveying and attaching the curtain wall to a predetermined position of a building while the elevation beds are continuously elevated, their heights being uniformly maintained. CONSTITUTION:During ascent of elevation beds 3 coupled together, the present positions of the beds 3 are detected by distance meters 12 corresponding respectively to elevating devices 8. Next, a microcomputer 18 computes and monitors errors in the levels of the beds 3, and automatically stops the beds 3 if any abnormality is detected. Then, if the errors in the levels fall within a controllable range, the frequency of an inventer 16 is controlled at a low, middle or high rate so as to control the elevating devices 8 in order to automatically control the errors in the levels of the beds 3 within a predetermined range. Further, the beds 3 are elevated to and stopped at a predetermined positions in a manual mode, and thereafter the curtain wall is connected to the previously installed one. Further, the beds 3 are automatically lowered to a position where a next curtain wall is assembled. With this arrangement, it is possible to safely and rapidly elevate a wide curtain wall.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measurement control device and a control method for attaching and removing an exterior curtain wall during exterior construction of a building. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measurement control device and a control method for holding a horizontal value of a lifting platform which repeats vertical transportation to a predetermined position on the lower floor of a building and repeats vertical transportation.

[0002]

2. Description of the Related Art Conventionally, an exterior wall of a building is composed of a metal panel system and an aluminum curtain wall system, and a paneled curtain wall is used as the exterior wall.
These curtain walls are manufactured in advance as a panel unit in the factory, transported to the construction site according to the progress of the construction site, and attached according to the building structure of the building.

The panel system that is made into the panel unit can be mounted by directly using the crane installed on the roof of the building and hoisting it directly from the ground or on a truck and mounting it from the bottom, or by using an aluminum curtain wall system. In the curtain wall, the frame material and the glass of the curtain wall are once arranged on each floor, the frame material is fixed to the building, the glass is inserted, and the sealing material is loaded and attached.

Other Japanese Patent Application No. 5-
As described in No. 204057, the width of the outer wall surface of the building may be one lifting rack or a divided lifting rack,
Each elevating platform is equipped with an elevating device (electric chain block) and independently elevates and lowers independently to attach the curtain wall. The horizontal value of the elevating platform is measured and controlled by the mounting method. A height detecting sensor for transferring the wall to a predetermined position, a height detecting sensor, and a converter for converting a detection data signal of the sensor,
A digital counter for displaying the signal of the converter at the height of the lifting platform, a monitor for inputting the signal and displaying a calculation result, an operating device connected to the microcomputer for operating the lifting platform, and an electric device. When installing the curtain wall, the horizontal value is automatically measured when the elevating platform moves up and down by the elevating means, and when the horizontal tilt value exceeds the allowable value, an alarm is issued and automatically. The elevating device is stopped, and also when the predetermined mounting height is reached, the curtain wall is mounted by manually operating the operating device as necessary.

[0005]

However, as described above, in the case of mounting the curtain wall formed into a panel unit as described above, a qualified operator can directly operate the crane installed on the roof or directly operate the electric chain block. In addition, since the object to be lifted is separated from the operator who operates it, the operation is performed while communicating with a hand signal from the installation site or by a radio device, so a considerably skilled operator is required, and communication with a hand signal or radio device is required. It is very dangerous for the support in the case that there is an operation error due to a mistrust.

Further, like the latter, the width of the outer wall surface of the building is either one elevating platform or divided, and each elevating platform is equipped with an elevating device (electric chain block) to independently elevate and lower the curtain independently. In the measurement control device of the lifting platform in the mounting method for attaching the wall, it can be applied to the exterior wall of the building with a narrow width or a building with a high height, but the exterior wall of a large building has a wide exterior wall. It was found to be unsuitable for a measurement control device for mounting an exterior curtain wall with a high height and a high lift.

That is, when mounting the exterior curtain wall, the horizontal value is automatically measured when the elevating platform is moved up and down by the elevating means, and when the horizontal inclination value exceeds the allowable value, an alarm is issued and the elevating device is automatically operated. A device that mounts the curtain wall by manually operating it as needed, so that it stops even when it reaches the planned mounting height, and supports one elevating platform along the width of the outer wall surface Then, an elevating device consisting of several guide rails and several hoisting means (electric chain block) is installed, the curtain wall is assembled to the elevating stand, and the elevating device conveys it to a predetermined height. The lifting means (electric chain block) equipped with heavy means cannot be hoisted at a constant hoisting speed, and the long elevating pedestal causes the land to become uneven, and the exterior is assembled to the elevating pedestal. Over ten Wall Kitashi the deformation, rather than just the mounting accuracy is deteriorated lacking in safety.

If the conventional apparatus is used, for example, an error of 10 mm per 10 m occurs in the lifting height, and the winding operation is stopped and adjusted each time. Therefore, it is necessary to make several adjustments on the exterior surface having a high lifting height, and the lifting work is performed. Will be significantly reduced and work efficiency will deteriorate. Further, when the exterior curtain wall is assembled and lifted up and down independently on the divided elevating mounts, the exterior curtain walls cannot be continuously joined in the vertical direction. (It is possible when the wall surface is uneven) This proposal is proposed in view of the problems of the above-described conventional technology, and its purpose is to install and measure a conventional exterior curtain wall with a measurement and control device. By adapting to a large-scale building, that is, a wide outer wall and an exterior curtain wall with a high lift, the elevator platform is continuously moved up and down while maintaining a certain height as the elevator platform is deformed. (EN) Provided are a measurement control device and a control method for mounting an exterior curtain wall, which contributes to high efficiency of the exterior curtain wall, work efficiency, labor saving, and safety.
