Abstract

The invention discloses an assembled prefabricated stair and a preparation device thereof. The assembled prefabricated stair comprises a base, wherein a demolding mechanism is arranged in the middle position of the top end of the base, and the demolding mechanism comprises step plates, ventilation cavities, air guide pipes, sliding plates, mounting frames, guide rods, connecting frames, placement grooves, a sliding groove, sliding blocks, ejector rods and sealing films; and the step plates are symmetrically welded to the middle position of the top end of the base, and the ventilation cavities are formed in the opposite ends of the two step plates. According to the assembled prefabricated stair and the preparation device thereof, hot steam can be conveniently injected into the ventilation cavities through the air guide pipes, and therefore, the step plates can be conveniently heated; through the cooperation of the placement grooves and the sliding groove, the sliding blocks can conveniently slide, so that the two mounting frames are conveniently spliced, and the two sliding plates are combined; and meanwhile, through the ejector rods and the sealing films, air is conveniently injected into the ventilation cavities, so that contact parts of concrete and the step plates are separated through thermal expansion and cold contraction, and the inner sides of two stair base bodies are conveniently demolded.

Description

technical field [0001] The invention relates to the technical field of preparation of prefabricated stairs, in particular to an assembleable prefabricated staircase and a preparation device thereof. Background technique [0002] Prefabricated stairs are quick to install, and compared with traditional cast-in-place stairs, it saves a lot of formwork support, steel bar binding and concrete pouring workload. The site only needs to be hoisted in place, and simple seam processing is enough, and the construction period and cost are saved. Compared with traditional stairs, precast concrete stairs do not need to set up complex frames when building stairs, and do not need to consider whether the weather is suitable, and do not need to spend a lot of time mixing and pouring concrete, so that precast concrete stairs are more convenient than traditional stairs. much faster; [0003] However, the existing prefabricated stairs and their preparation devices lack the components that are co...
