Lightweight ceramsite concrete assembly type prefabricated hollow staircase and preparation method thereof

Abstract

The invention discloses a lightweight ceramsite concrete assembly type prefabricated hollow staircase and a preparation method thereof. The hollow staircase is molded by pouring lightweight ceramsiteconcrete, and comprises hollow-column steps, steel bars and hoisting rings, wherein the insides of the hollow-column steps are poured into circular hollow holes; the steel bars are pre-embedded in thelightweight ceramsite concrete; the hoisting rings are arranged on the steps; the lightweight ceramsite concrete is prepared from cement, mineral powder, fly ash, fly ash ceramsite, water-quenched slag, pearlite sand, water and an admixture. According to the lightweight ceramsite concrete assembly type prefabricated hollow staircase, the fly ash ceramsite is taken as aggregate of concrete insteadof natural stones, so that non-renewable resources are saved; the lightweight ceramsite concrete assembly type prefabricated hollow staircase is a green, ecological and environment-friendly buildingmaterial, and has significant significance for solving of the problem of shortage of building material production resources and environmental protection.

Description

technical field [0001] The invention relates to the technical field of stairs, in particular to a lightweight ceramsite concrete assembled prefabricated hollow staircase and a preparation method thereof. Background technique [0002] The ultimate goal of the transformation and upgrading of the construction industry is to realize the modernization of the construction industry. As one of the main production methods of construction industrialization, prefabricated concrete prefabricated buildings (PC) have outstanding performance in saving resources and reducing energy consumption, and are developing rapidly at this stage. However, at present, most high-rise prefabricated buildings use ordinary concrete prefabricated stairs, which have the disadvantages of heavy weight, high transportation costs, and difficult hoisting. Therefore, it is particularly important to develop a lightweight ceramsite concrete that can make up for the shortcomings of ordinary concrete. [0003] Lightwe...

AI Technical Summary

Problems solved by technology

Excessive mining of natural stone will lead to natural disasters such as soil erosion and landslides, which will greatly aggravate the deterioration of the ecological environment

In addition, if the industrial solid wastes such as fly ash and slag are not handled properly, it will not only lead to the occupation of a large amount of cultivated land, but also its harmful components will enter the environment through water, air and soil, causing long-term and potential harm to human beings.
