Description
Technical Field
The invention relates to the technical field of installation of a temporary overhanging curtain wall, in particular to a temporary overhanging curtain wall structure and an installation method.
Background
In modern buildings, aluminum plate curtain walls are widely used due to the advantages of light dead weight, convenient forming, strong metal texture, adjustable color and the like, and besides the large-area continuous dry hanging application on building facades, the aluminum plate curtain walls are increasingly used as cornices and lines with various shapes. In high-rise buildings, particularly super high-rise buildings, the cornices of interlayer lines and tops are always in a high-altitude temporary state, no ready work platform exists, and the problems of how to arrange a high-altitude construction platform, how to efficiently install and ensure the safety of operators become troublesome engineering. The molding cornice is formed by enclosing four aluminum plates into a closed cavity, the aluminum plates on the top and the bottom are required to be installed generally, if a hanging basket is adopted for construction, the aluminum plates on the bottom cannot be installed due to interference of a hanging basket steel wire rope and the aluminum plates, and therefore a feasible and convenient method for installing the overhanging curtain wall in the open air is urgently needed.
The current on-site manufacturing flow of the aluminum plate curtain wall is as follows: cutting and blanking the steel section according to the modeling specification on site; welding and forming a steel member; the aluminum plates were mounted block by block. Three methods for building a construction platform in the sky are provided: a. and (3) a full scaffold, b, a temporary cantilever construction platform and 3, a hanging basket. However, the existing curtain wall installation method has the following defects:
1. all cutting, welding and plate mounting operations are performed on site, so that the on-site manufacturing and mounting work content is more, the working intensity of workers is high, the mounting efficiency is low, and the mounting quality is unstable under the influence of human factors;
2. the construction platform is technically infeasible to erect full scaffold from the ground when the high-rise is in the sky, the construction platform is huge in cost, and the construction platform needs to be repeatedly erected when being constructed at different heights and different positions;
3. when the hanging basket is used for construction, due to interference of the hanging basket steel wire rope and the aluminum plate, part of the aluminum plate on the bottom surface cannot be installed.
