In recent years, under the vigorous promotion of national policies, the enthusiasm of related enterprises in our country to participate in assembly is increasing, and the scale of the industry is also expanding year by year. Assembly construction management, quality control and acceptance, and safety management are constantly improving, ensuring the quality and Construction safety. Among them, stairs are a kind of prefabricated concrete components, which are currently widely used in domestic assembly. In order to continuously improve the product quality of enterprises and reduce the occurrence of quality problems in engineering construction, this article mainly explains some common prefabricated stairs in the production process. Quality prevention and treatment methods.

1. What is a prefabricated staircase

Prefabricated stairs are one of the commonly used components in prefabricated buildings. They are produced in the component factory and finally transported to the construction site for installation. After installation, they can be used as on-site construction channels immediately, which is convenient and fast.

In the production of prefabricated stairs, the embedded parts of the handrails can be buried in advance, and the anti-skid strips, drip lines and other structures can be cast in a fixed mold production, reducing the secondary treatment process of the on-site stairs; and the prefabricated stairs are of higher quality and better look and feel than the cast-in-place stairs. , Has the beautiful effect of fair-faced concrete.

Analysis of Quality Problems of Prefabricated Stairs
Second, the production method and process flow of prefabricated stairs

The production methods of prefabricated stairs in the component factory mainly include horizontal production and vertical production.

Compared with the vertical type, the horizontal stair mold is more convenient to place the steel cage and pouring the concrete, but the stairs produced by the horizontal mold will have one more turning process when the mold is removed and stacked, and the embedded parts are installed more than the vertical type; The drip line on the back of the stairs also needs to be manually formed by layering, while the vertical type can be formed at one time through a mold.

In addition to the troublesome installation of steel bars and the risk of slurry leakage during concrete pouring, vertical molds are better in production convenience, efficiency, and molding quality than horizontal molds. Therefore, component factories generally use vertical production methods to make stairs.
