Description

Technical Field

[0001] The present application relates to the field of prefabricated buildings, and in particular to a prefabricated staircase. Background Art

[0002] At present, the manufacturing and installation of stairs mainly adopts the on-site construction method, which has problems such as long construction period, difficult to ensure quality, and poor environmental protection. With the development of prefabricated buildings, the prefabricated manufacturing and installation of stairs have gradually attracted attention.

[0003] An existing assembled staircase includes several prefabricated staircases; the prefabricated staircases include concrete staircases, an upper platform, a lower platform, and hanging holes; the upper and lower ends of the concrete staircases are respectively fixedly provided with an upper platform and a lower platform; two hanging holes are provided on the concrete staircase; the upper platforms and lower platforms of adjacent prefabricated staircases are sealed and connected by grouting material; anchor steel bars are provided in the upper platform and the grouting material, and in the lower platform and the grouting material.

[0004] For existing prefabricated stairs, the prefabricated stairs are an integrated structure, and the steps and the inclined stair treads are a whole. Due to the various existing building sizes, the requirements for the appearance and height of the steps of the prefabricated stairs are also different. Conventional prefabricated stairs produce molds of corresponding specifications according to the required specifications and sizes, and concrete is poured as a whole, which reduces the scope of application of the prefabricated stairs.
