TECHNICAL FIELD
[0001] The present application relates to the technical field of prefabricated stairwell construction, and more particularly to a prefabricated stairwell assembly type construction operation platform and method. BACKGROUND
[0002] With the development of the construction industry, prefabricated buildings have been widely recognized. Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories, where building components and accessories (such as floors, walls, stairs, balconies, etc.) are processed and manufactured, transported to the construction site, and assembled and installed on site through reliable connection methods. Prefabricated stairs are one of the commonly used components in prefabricated buildings, and the prefabricated components of prefabricated stairs are mainly concrete prefabricated steps, platform plates, and supporting structures. The main support methods of stairs are divided into wall bearing type, cantilever step type, and beam bearing type, which have the advantages of high efficiency, fast construction speed, and high quality controllability.
[0003] The prefabricated stairwell assembly is shown in the structure of the accompanying drawings Figure 1 As shown in the structure of the accompanying drawings, the stairwell has reserved steps for ascending and descending, both of which are horizontally extended through the building walls on both sides, and the building walls form the stairwell. At present, by connecting the prefabricated stairs between the steps for ascending and descending and fastening, the rapid construction and formation of the walking stairs can be realized.
[0004] However, from the actual construction process, it is found that in prefabricated buildings, prefabricated stairs often lag behind the construction operation surface, sometimes lagging behind multiple layers. In the stairwell (layer) without prefabricated stairs, other construction operation projects such as pipeline laying, line pre-burying, and wall painting are usually required, and an operation platform is usually needed during such construction. Due to the limitations of the structure of the construction operation platform itself and the site conditions, the prefabricated stairwell construction operation platform has certain limitations and safety hazards. The commonly used construction methods are: directly erecting a landing scaffold (only suitable for lower floors); or erecting a stirrup on the lower side of the stair platform, and then erecting a construction platform; or directly erecting a wooden jump board on the scaffold as a construction platform; or using a steel pipe to erect a support frame as an operation platform, etc. The above methods all have certain safety hazards in actual operation, and the construction platforms are not convenient for lifting and moving, causing construction difficulties, and the construction of the stairwell is difficult due to the limitations of the stairwell.
