Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and in particular to a force-bearing support system of an outwardly protruding cantilever structure for erecting a construction platform and a high-rise building repair method. Background Art

[0002] During the renovation of the facades of high-rise buildings, we often encounter protruding cantilever structures of the buildings, such as fire corridors, protruding balconies, etc., which affect the renovation of the upper facades of the protruding cantilever structures. When the facades are repaired by erecting scaffolding on the ground as a construction platform, the obstruction of the protruding cantilever structure affects the erection of the scaffolding. In order to repair the facades of high-rise buildings, two treatment methods are currently used. One is to erect a suspension frame by opening a hole in the protruding cantilever structure, and the other is to erect a scaffold directly on the protruding cantilever structure. When the protruding cantilever structure is opened, the verticality of the scaffolding on the protruding cantilever structures of each floor cannot meet the requirements of the specifications due to reasons such as obstructed vision and plumb bob collision. In addition, the local opening of holes in the protruding cantilever structure brings safety hazards to the protruding cantilever structure. When scaffolding is erected on the upper part of the protruding cantilever structure, the force on the protruding cantilever structure greatly exceeds the structural design requirements and the construction load of the scaffolding as a construction work platform. The protruding cantilever structure is likely to collapse, which can easily cause construction safety accidents. Summary of the invention

[0003] The purpose of the present invention is to provide a force support system for an outwardly protruding cantilever structure for setting up a construction work platform and a high-rise building repair method, so as to solve the safety hazard problem that setting up a scaffolding on the upper part of the outwardly protruding cantilever structure as a construction work platform leads to insufficient force load on the outwardly protruding cantilever structure, which easily leads to construction safety accidents.
