Embodiment 1

[0024] The invention discloses a prefilled aggregate decorative concrete staircase, the specific steps are as follows:

[0025] (1) Clean the mold, caulk the seam, apply release oil, install hanging nails, and bind steel bars;

[0026] (2) Spread the stones evenly in the mold to make them accumulate naturally;

[0027] (3) Pour the well-mixed cement slurry into the mold until the cement slurry fills the gaps, covers the stones, and no longer sinks;

[0028] (4) Sprinkle water after removing the formwork, cover the film for maintenance for 4 days, and then polish the surface until the stones are ground out;

[0029] (5), replace the abrasive disc, use 800 mesh, 1000 mesh, 1500 mesh, 2000 mesh, 3000 mesh abrasive disc to grind and polish respectively.

[0030] In the described step (2), during the accumulation of stones, the upper surface of the stones will be piled up smoothly to avoid heaping.

[0031] In the step (3), during the process of pouring the cement slurry into th...

Embodiment 2

[0036] The invention discloses a prefilled aggregate decorative concrete staircase, the specific steps are as follows:

[0037] (1) Clean the mold, caulk the seam, apply release oil, install hanging nails, and bind steel bars;

[0038] (2) Spread the stones evenly in the mold to make them accumulate naturally;

[0039] (3) Pour the well-mixed cement slurry into the mold until the cement slurry fills the gaps, covers the stones, and no longer sinks;

[0040] (4) Sprinkle water after demoulding, cover with film and maintain for 3 days, and then polish the surface until the stones are removed;

[0041] (5) Replace the grinding disc and use a 1000-mesh grinding disc for grinding and polishing.

[0042] In the described step (2), during the accumulation of stones, the upper surface of the stones will be piled up smoothly to avoid heaping.

[0043] In the step (3), during the process of pouring the cement slurry into the mold, the mold is opened to vibrate to assist the flow of t...

Abstract

The invention discloses a prepacked aggregate concrete decoration concrete stairway. The stairway is prepared by the following concrete steps: cleaning a mold, performing caulking, brushing mold releasing oil, installing hanging nails, and binding reinforcing steel bars; spreading stones uniformly in the mold, and enabling the stones naturally accumulated; pouring a uniformly-stirred cement slurryinto the mold until the cement slurry fills a gap, and covering the mold by stones until the mold no longer sinks; spraying water after the mold is removed, performing covering by using a film, performing maintenance for 3-5 days, and performing surface grinding until stones are ground out; and replacing a grinding disc, and performing grinding polishing by using a grinding disc with 800 meshes or more, wherein the cement slurry is prepared from the following components: 500-800 parts of cement, 80-120 parts of fly ash, 180-280 parts of water, 8-13 parts of a high-performance water reducing agent and 10-20 parts of latex powder. The stairway provided by the invention has the advantages of saving manpower and physical power, being convenient for operation, having good effects and the like.

Description

technical field [0001] The invention relates to the field of concrete staircase preparation, in particular to a prefilled aggregate decorative concrete staircase and a preparation method thereof. Background technique [0002] At present, my country's economy is developing rapidly, and the construction industry is gradually transitioning from traditional cast-in-place construction to prefabricated structures. [0003] The quality of the prefabricated structure is easy to control, and the shape is diverse, which provides favorable conditions for the integration of concrete decoration. The concrete pouring of traditional building stairs is mainly cast-in-place. After the concrete is formed, the surface is uneven, the lines are not smooth and straight, and the production effect is poor. , needs to be reprocessed and modified in the later stage. Ordinary prefabricated stairs are produced by molding the stairs as a single component, and then mix and mix the stones and concrete, bu...
