As a comprehensive large-scale garden project, the previous garden expo has a large volume and a large amount of investment. The use and display of new garden data is extensive and novel. Many new garden data are used in the planning and construction, such as clear water concrete, PC bricks, and exposed concrete , Glass bricks, weather-resistant steel plates, slate, gabion retaining walls, bamboo materials, glass mirrors, glass fiber reinforced plastics, etc., provide a display and reference for the innovative use of garden planning materials. The following introduces us to a new type of garden materials-PC brick.
Development of PC materials
Prefabricated Concrete Structure, abbreviated PC, means "prefabricated concrete structure". As a form of residential industrialization, developers (such as Vanke and Longhu) are favored by their advantages such as high efficiency, high cost performance, energy saving, environmental protection, and consumption reduction. This technology is widely used in Japan and China ’s Hong Kong region, and has become the mainstay of the industrialized housing market in the two places, but it is still in its infancy in China. It integrates the advantages of colored concrete bricks, natural marble, and granite, which is in line with the national strategy of energy conservation and emission reduction and sustainable development. Therefore, after years of development, PC products have been successfully used in the new information market.
Scenery use of PC materials
The use of PC information products in scenes mainly includes square road tiles, roadside stones, scene sketches, and various structural parts used in scenes. At present, it is mainly used in commercial and residential real estate communities, including landscape roads, wall, small scenes, commercial squares and municipal roads. After replacing traditional cement bricks and stone, it completes the paving of imitation stone and completes the construction of low-cost scenery. And then arrive at the development and construction of cost reduction and efficiency.
Craft of PC brick
1. Crush the corresponding formula of natural stone powder into different mesh sizes, mix rock chips, mica flakes or different inorganic color matching sheets with different effects, and high-grade cement, certain additives, brighteners or waterproof inorganics. The data is shake-molded according to a certain proportion.
2. After steam maintenance, the second floor is finished with C40 grade concrete for the second distribution, the second shock is compacted, the second steam seal maintenance, demoulding, natural maintenance and circulating water maintenance after demoulding.
3. Use professional sand blasting equipment or corresponding milling or water-milling machines to uniformly grind fire, litchi, stripes or checkered pictures (equivalent to various grinding methods of stone) on its appearance, and finally show the natural stone. Texture and effect.
In previous hard paving of squares and roads in previous garden fairs, many used new materials PC bricks instead of traditional permeable bricks, which can not only complete the role of all imitation stone paving, but also complete the balance of comprehensive project cost, and develop for the current foundation. The completion of the "cost reduction and efficiency improvement" initiated by the construction provided new materials for selection.
