Technical Field
[0001] The utility model belongs to the technical field of high-rise building protection, and in particular relates to a multifunctional steel cantilevered horizontal protection shed. Background Art
[0002] With the development of modern society, the status of high-rise buildings in cities is becoming more and more important. High-rise buildings can not only provide more living and office space, but also become the landmark and symbol of the city. During the construction of high-rise buildings, it is difficult to avoid vertical cross-operation. When the height of high-altitude operations is greater than 30m, a 6m wide horizontal protective shed needs to be set up to ensure the safety of vertical cross-operation. For real estate projects, the ultimate goal of the project is sales, and all activities of the project are carried out around sales. In order to ensure sales, most developers will give priority to the construction of model display areas. A horizontal isolation shed will be set at the junction of the constructed floors and the unconstructed floors on the facade of the display area to achieve an aesthetic effect. The present invention is to study a multifunctional steel cantilever horizontal protective shed, which combines the functions of two horizontal protective sheds into one, with both anti-smashing and anti-falling functions, as well as aesthetic functions, while also taking into account the functions of publicity and display, rain protection, etc., and is formed in one construction, saving construction period.
[0003] At present, the horizontal protection sheds of high-rise buildings generally adopt two types: fastener-type cantilever protection sheds and steel cantilever protection sheds. The isolation sheds in the exhibition area generally adopt the form of light steel structure plus advertising. The fastener-type cantilever protection shed uses steel pipes and fasteners to form the main structure of the protection shed, and the plane is covered with safety nets or bamboo scaffolding boards, and is fixed to the main structure of the building with steel wire ropes and embedded parts; the steel cantilever protection shed uses steel, steel pipes and fasteners to form the main structure of the protection shed, and the plane is covered with safety nets or bamboo scaffolding boards, and is fixed to the main structure of the building with steel wire ropes and embedded parts; the main function of the exhibition area isolation is aesthetics and publicity display, and generally adopts a light steel structure (square tube, angle steel, etc.) skeleton, wrapped with advertising cloth on the outside, and fixed to the main structure of the building with steel wire ropes and embedded parts. Among them, the horizontal protection shed only has the function of anti-smashing and anti-falling, and the plane is generally a safety net or bamboo footboard, which is not beautiful in appearance. The horizontal isolation shed that isolates the exhibition area from the construction area has a beautiful appearance, but is generally single-layer, and the cantilever length is not enough, and it cannot play a role in safety protection. The two types of horizontal sheds need to be constructed separately, and the construction period is long. In view of the existing shortcomings, it is urgent to research a horizontal protective shed that has anti-smashing and anti-falling functions, beautiful appearance, and also takes into account publicity, display, and rain protection. It can be completed in one construction and save construction time. Summary of the invention
