Construction method for suspension type operating platform of outer wall steel structure and curtain wall of high-rise building

Abstract

The invention relates to a construction method of a suspension type operating platform for an outer wall steel structure and a curtain wall of a high-rise building. The construction method is characterized in that a chassis platform is placed below a cantilever frame through hoisting; a suspension frame is erected between lifting lugs of the cantilever frame and a floor slab; and during construction, a constructor enters the chassis platform through a crawling ladder to construct the outer wall, after steel beams and brackets on the outer wall are welded, the constructor returns to the floor slab through the crawling ladder. The method is convenient to operate, manufacturing can be completed through idle peripheral materials on site, the hoisting process can be achieved through a tower crane, the integrity of the platform is good, people can get in and out of the platform only through the crawling ladder, bracket welding, antirust paint brushing and other operations of the arc-shaped steel beams can be completed on the platform, construction operation of an outer wall steel structure, a curtain wall keel and the like can be met through the cantilever frame, the suspension frame andthe chassis platform, the method is safe, controllable, time-saving and efficient, the utilization rate of peripheral materials is increased, the cost is reduced, and the problem that an arc-shaped outer wall is difficult to construct is solved.

Description

technical field [0001] The invention relates to the construction field, in particular to a construction method for a suspended operating platform of a high-rise building exterior wall steel structure and a curtain wall. Background technique [0002] In recent years, with the sudden emergence of high-rise buildings and super high-rise buildings, the shape of building exterior walls has become more and more complex, and the shape of exterior curtain walls has more and more arc lines. The skeleton of exterior curtain walls needs steel structures to support them. In order to ensure the beautiful curved appearance of the outer curtain wall and to be well fixed and connected with the keel of the curtain wall, arc-shaped steel beams are usually welded on the outer wall of the building. Embedded parts need to be fixed by welding, and an operating platform is required for welding operations. Since many high-rise buildings use overall lifting scaffolding, after the overall lifting of...

Problems solved by technology

Since many high-rise buildings use overall lifting scaffolding, after the overall lifting of the scaffolding, the periphery of the outer wall is in a suspended state. During the construction stage of the main structure, the construction layer cannot fix the hanging basket, and the hanging basket cannot be installed, causing great trouble to the construction workers.
