Embodiment 1

[0015] Embodiment 1: A construction method of cast-in-place terrazzo ground, (1) base treatment; (2) watering and moistening; (3) ground bottom ash punching ribs; (4) laying bottom ash; ; (6) inlaid partition strip; (7) brushing the bonding layer; (8) spreading stone slurry; (9) rolling compaction and spreading and flattening; (10) trial grinding; (11) coarse grinding; ( 12) fine grinding; it also includes: (13) concrete curing agent; (14) fine grinding; (15) terrazzo surface crystal plane treatment; wherein,

[0016] (8) Spreading stone slurry: In order to make the cast-in-place terrazzo ground be ground and polished with zero dead ends, adjustments are made in the construction process. The pipelines passing through the ground are installed after the construction of the ground is completed. Reserve the holes for sealing, turn over the 300mm high wall from the ground and do not plaster for the time being, so that the grinder can be better polished in place, and after the groun...

Embodiment 2

[0023] Example 2: A university life science laboratory building and annex building project, one basement floor, twelve floors above ground, four annex buildings, frame shear wall structure, with a total construction area of ​​73129㎡. The project was constructed using the new cast-in-place terrazzo ground construction method in Example 1, which saved a total cost of 896,000 yuan. Due to the reduction of pickling and waxing processes, the construction period was shortened by about 40 days, which effectively solved the possible problems in the construction of terrazzo ground. Some quality problems, and achieved good social and economic benefits.

Embodiment 3

[0024] Example 3: The 1# student apartment building project of a university has four floors above the ground, frame shear wall structure, and a total construction area of ​​12,426 square meters. The project is constructed using the new cast-in-place terrazzo ground construction method in Example 1, saving a total cost of 246,000 yuan , due to the reduction of pickling and waxing processes, the construction period is shortened by about 20 days, and it has won unanimous praise from the school and students during use, and has achieved good social and economic benefits.

Abstract

The invention discloses a novel cast-in-place waterstone ground surface layer construction method. The novel cast-in-place waterstone ground surface layer construction method comprises the following steps: (1) treating a base layer; (2) pouring water and wetting; (3) carrying out ground bottom ash screeding; 4) paving bottom ash; (5) carrying out mesh division by elastic lines; (6) embedding dividing strips; (7) brushing a bonding layer; (8) paving stone particle slurry; (9) rolling compactly, and paving and flattening; (10) carrying out trial grinding; (12) finely grinding; (13) feeding a concrete curing agent; (14) precisely grinding; (15) carrying out crystal face treatment on the surface of a waterstone. The novel cast-in-place waterstone ground surface layer construction method has the advantages that the surface smoothness of the waterstone is high; the surface hardness reaches Grade5-7; the waterstone has permeation resistance and is waterproof and dirt-proof, has the water permeation rate of being less than 0.8, and is oil-proof, weak-acid-proof, weak-alkali-proof and salt-fog-proof; the comprehensive performance of natural protection exceeds that of any existing stone product; a cast-in-place waterstone ground has zero dead angle when being ground and polished, and the ground appearance quality is greatly improved when being compared with that of a traditional method.

Description

technical field [0001] The invention relates to a construction method for a terrazzo ground surface, in particular to a construction method for a cast-in-place terrazzo ground surface. Background technique [0002] Terrazzo floor is a kind of composite floor material with cement as the main raw material. It is widely used in super-large public buildings because of its low cost, good moisture-proof performance, arbitrary color mosaic, and convenient construction. According to the statistics of relevant national departments, the use area of ​​terrazzo in public buildings in the country exceeds 6 billion square meters. Hospitals, pharmaceuticals, machinery, government agencies, schools, commercial places, airports, stations and docks have huge markets in China. [0003] The traditional terrazzo floor construction method is to carry out polishing treatment after fine grinding. After polishing, in order to obtain a significant effect after waxing, the terrazzo surface layer shoul...
