Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a turnover and lifting type protection platform for the inner patio of a fire corridor. Background Art

[0002] In the construction of high-rise buildings, the safety protection of the inner patio area of the fire corridor is a key link to ensure construction safety. The fire corridor is usually located in the middle and high floors of high-rise buildings, connecting different units or the main building. When the length of the fire corridor exceeds the specified limit value, it is necessary to optimize the smoke exhaust and evacuation conditions through the patio to ensure compliance with the building fire protection design. As a vertically penetrating hollow area inside the building, the inner edge of the patio lacks physical enclosure. If construction workers do not take effective protection measures, they are extremely likely to fall from above the patio, resulting in high-altitude falling accidents.

[0003] Chinese Patent CN212926977U discloses a turnover type operation platform for the inner patio of a high-rise fire corridor. The operation platform mainly consists of an operation platform and several parallel support frames. The specific structure of the support frame is that a vertical support rod is provided at one end of the lower surface of the operation platform, and an inclined support rod is provided at the other end of the lower surface of the operation platform. The vertical support rod and the inclined support rod form a right-angled triangle support surface, and the inclined support rod continues to extend downward. A vertical clamping rod is connected to the lower part of the inclined support rod, and a triangular clamping interface is formed between the lower end of the inclined support rod and the clamping rod. This patent can be directly hung on the fire corridor without any screw or bolt connection, and the construction is fast and convenient. However, the structural adaptability is poor and it cannot be applied to the patio area with a long and narrow space and an air-conditioning board blocking in the middle. Especially in the construction of high-rise residential buildings, the air-conditioning board at the inner patio of the fire corridor will hinder the layout of the operation platform, and during the turnover use, the disassembly and transfer process of the operation platform is time-consuming and laborious, and it cannot meet the construction requirements under complex structures.
