Example Embodiment

[0033] Example 1

[0034] Such as figure 1 As shown, in this embodiment, the lightweight ceramsite concrete fabricated prefabricated hollow staircase includes step holes 1, steel bars 2, lightweight ceramsite concrete 3, steps 4, and hoisting rings 5. Each step is prefabricated with at least one step hole , The step hole has a circular structure, so that the step forms a hollow column step.

[0035] The raw material components and weight ratio of lightweight ceramsite concrete are: cement: slag powder: fly ash: fly ash ceramsite: water quenched slag: pearl sand: water: admixture = 280:210:55:600: 520:16:150:14. Among them, the cement is 42.5 grade ordinary Portland cement, which can be Zhengtong 42.5 grade ordinary Portland cement produced by Tianjin Zhenxing Cement Co., Ltd.; the mineral powder is S95 grade mineral powder, which can be used by Tangshan Ruifeng Iron and Steel (Group) Co., Ltd. Grade S95 granulated blast furnace slag powder produced by the company; fly ash is gra...

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...
