Prefabricated stair and production and construction method thereof

Abstract

The invention discloses a prefabricated stair and a production and construction method thereof, and belongs to the field of prefabricated stairs, the production and construction method comprises the following steps: assembling a bottom die: assembling the bottom die into a standard kicking surface height and a tread height of stone reverse hitting, and reserving a stone thickness for the kicking surface height; the back face of the stone is coated with a waterproof interface agent, anchoring holes are drilled in the stone and filled with a binding agent, claw nails are fixed to the anchoring holes of the stone, filling holes are formed between the claw nails and the back face of the stone, and then the front face of the stone is positioned at the corresponding tread and kicking face positions of the bottom die; waterproof sealing treatment is carried out on the appearing joints; mounting a reinforcement cage: hoisting the reinforcement cage to the bottom die; assembling a side mold; pouring concrete; the prefabricated stair comprises a stair body, stone and a reinforcement cage. According to the prefabricated stair and the production and construction method thereof, the stone and the stair body are firmly connected, the integrality is good, the waterproofness is good, the environmental applicability is high, field installation is easy, and the influence on the installation environment is small.

Description

technical field [0001] The invention relates to the field of prefabricated stairs, in particular to a production and construction method of prefabricated stairs. Background technique [0002] It is often necessary to set up outdoor stairways in urban parks, and the parks are mostly located near residential areas or on mountains in the city; outdoor stairways need to be paved with stone decoration after construction; stairways constructed by cast-in-place are not only It needs to occupy a large construction area, waste a lot of supporting materials and a large number of formwork, and the construction site needs to set up a large area of ​​steel bar processing and production areas, material stacking sites, mortar mixing areas, etc. In the suburban mountainous environment, after the concrete is solidified, the support system needs to be dismantled and a large amount of construction waste is generated; moreover, the concrete pouring process is complicated in a limited space or i...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a production and construction method for prefabricated stairs, which at least solves the problem that the existing stone and prefabricated stairs are easy to fall off during use due to insufficient connection strength; especially when it comes to large-thickness stone paving, the on-site cutting loss is large and wasteful, and the weight of the stone is heavy. Heavy, manual paving is slow, and the paving effect is not good
