Outer cantilever frame for outer curtain wall construction and installation and construction method of outer cantilever frame

Abstract

The invention discloses an outer cantilever frame for outer curtain wall construction and a mounting construction method thereof.The outer cantilever frame comprises a pair of double-width five-stage frames arranged indoors, an indoor scaffold is built between the pair of double-width five-stage frames through a plurality of cross braces and inclined braces, and double-width three-stage frames are connected to the lateral upper portions of the double-width five-stage frames correspondingly; the pair of double-width three-stage frames is connected through a plurality of cross braces to form an outward-hanging part, and the indoor scaffold and the outward-hanging part are connected with platform plates through supports at the same height. Each vertical rod of the pair of double-width five-stage frames is connected with a vertical rod, and the upper end of each vertical rod abuts against an indoor top plate through a jacking assembly. The overhanging frame is simple in structure, easy to assemble and good in stability and safety, the scaffold arranged indoors is fully utilized as a stable support, the overhanging part can directly stretch out of a room, and construction operation of an outer curtain wall by constructors is facilitated.

Description

technical field [0001] The invention relates to the technical field of curtain wall construction, in particular to an overhanging frame used for exterior curtain wall construction and an installation and construction method thereof. Background technique [0002] The curtain wall is the outer wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large-scale and high-rise buildings. Composed of panels and supporting structure systems, it can have a certain displacement capacity relative to the main structure or itself has a certain deformation capacity, and does not assume the role of the main structure. The building envelope structure or decorative structure. [0003] During the construction of the curtain wall, it is necessary to set up scaffolding and working platforms so that the construction personnel can carry out the construction wo...

[0004] Disclosed as Chinese utility model patent (CN212715814U) a kind of scaffolding for construction of combined curtain wall, comprises vertical bar, cross bar and bearing bar, the scaffolding of this novel combined curtain wall construction has various functions, has satisfied the various needs in use, but For high-rise buildings, it is necessary to build a higher height, and it must be built along the outer wall, the workload is relatively large, and the safety is not guaranteed when the height is too high

[0005] Chinese utility model patent (CN201158933) discloses a scaffolding device for maintenance of high-rise overhanging structures. The device is composed of indoor square frame supports and outdoor cantilevered truss platforms vertically connected to each other. The top of the indoor square frame supports is provided with a top support. , the bottom is equipped with an adjusting screw and a universal roller. The device adopts an external cantilever structure, which reduces the cost of scaffolding construction, but the whole structure is still complicated, and it is not convenient to install and disassemble, and it is necessary to use a weight to adjust the balance.
