今天由上海压印地坪的小编给大家分享一下压印混凝土的施工工艺!希望通过小编的分享能对您有所帮助。
压印混凝土:
在未硬化的现浇混凝土基层上,通过着色、硬化、压印、脱模、养护、密封保护等多道工艺制成的较具艺术韵味的地坪或墙面。适用于室内、外地坪装饰,也可用于建筑物立面的装饰。
物理性能:
压印混凝土是由美国Bomanite公司创立,经过多年发展与完善,该产品在工艺的合理性、专用化学材料的稳定性与环保性以及装饰效果方面已达成了很成熟的水平。适用范围从室外发展到室内,从园林造景发展到娱乐、市政、商业和文化设施领域,并且以擅长承制具有较强艺术性和特殊装饰要求的地面工程而闻名。像美国的众多豪华酒店的室内外地坪,迪斯尼在世界各地的艺术地坪,还有主题公园如环球影视城和海洋世界的艺术地坪等等。
压印混凝土艺术地坪技术系统因其极强的艺术性、色彩和款式方面广泛的选择性,低成本和绿色环保性在中国有了迅速发展。在受到领导人充分肯定的上海市城市绿地发展项目中,彩色压印混凝土艺术地坪大面积推广和采用,实现了很好的社会效益和市场认可度。
压印混凝土是在摊铺好的砼表面上,在砼表面析水消失后用干撒彩色强化剂(干粉)的方法对砼表面进行上色和强化,并使用专用工具将彩色强化剂抹入砼表层使其融为一体;待表面水分光泽消失时,即均匀施撒彩色脱膜养护剂(干粉),并马上用事先选定的模具在砼表面进行压印,实现各种设计款式、纹理和色彩。待砼经过适当的清理和养护之后,在表面施涂密封剂(液体),使艺术地坪表面防污染防滑并再次强化。完成后的压印混凝土地坪除了具有很好的装饰性以外,其物理性能也非常稳定。
施工工艺:
1. 铺筑砼前按图规定和标高支模.人行道基层砼为50mm以上,行车道基层砼为80mm以上;
2. 摊铺标准砼.推荐配合比为:32.5水泥424KG,粗沙400KG,细沙400KG,石子(瓜子片)1100KG,水185-195KG;
3. 进行平板震动机交叉震动后用铁辊交叉提浆.100mm以下砼使用平板震动机作业, 100mm以上砼使用插入式振捣作业;
4. 用抄平尺进行找平后进行泌水处理,在表面初凝前用手工铁板将砼表面光平;
5. 将标准用量(4.5kg/㎡)的1/2欧进彩色硬化剂均匀播撒在初凝阶段的混凝土表面;
6. 待硬化剂荫湿后用手工铁板或大抹刀进行一次找平收光,不要过分铲抹混凝土表层,这样会导致表面出水并减弱色彩;
7. 将剩下的硬化剂补撒在一次未撒匀的地方, 待荫湿后第二次收光;
8. 在硬化剂初凝后, 表面干燥无明显水份的情况下,播撒欧进着色脱模粉(标准用量为0.15kg/m2)后压模. 压模时要用力应均匀一致, 保持模具固定平整, 压制图案要一次成型, 不能反复压印;
9. 待混凝土压花地坪完全干燥凝固成型至少3-7天后,进行修边及伸缩缝的切割, 割缝时及时用水冲洗割缝时产生的水泥浆;
10. 用水或去污剂清洗表面, 清洗擦刷表面必须要保证整个地坪清洗程度一致,否则会造成地面颜色深浅不一;
11. 冲洗的地坪表面干燥后,涂刷欧进亮光养护剂. 使压模地坪表面防污染防滑性能再次加强. 完成后的硬化压模地坪除了很好的装饰性以外,其物理性能也非常稳定.
Today, by the Small series of Shanghai floor to share the construction technology of concrete imprint!Hope to share through small make up can be helpful to you.
Imprinted concrete:
In unhardened cast-in-place concrete base, through coloring, hardening, embossing, stripping, curing, sealing protection and other processes made of more artistic charm of the floor or wall.Suitable for interior, exterior floor decoration, also can be used for building facade decoration.
Physical properties:
Founded by Bomanite corporation of The United States, imprinted concrete has reached a mature level in terms of rationality of process, stability and environmental protection of special chemical materials and decorative effect after years of development and improvement.The scope of application extends from outdoor to indoor, from garden construction to entertainment, municipal, commercial and cultural facilities, and is famous for undertaking ground works with strong artistic and special decorative requirements.The indoor and outdoor floors of many luxury hotels in the United States, Disney's art floors around the world, and theme parks like Universal Studios and SeaWorld's art floors.
Embossed concrete art floor technology system because of its strong artistic quality, color and style of extensive selection, low cost and green environmental protection in China has a rapid development.In the urban green space development project of Shanghai, which has been fully recognized by the leaders, the colored imprinted concrete artistic floor has been widely promoted and adopted, which has achieved good social benefits and market recognition.
The embossed concrete is painted and strengthened on the surface of the paved concrete by means of dry sprinkling color intensifier (dry powder) after the water evaporates on the surface of the concrete. Special tools are used to rub the color intensifier into the surface of the concrete to make it into a whole.When the surface moisture gloss disappear, that is, evenly sprinkle color off the film maintenance agent (dry powder), and immediately with the mold selected in advance on the concrete surface for imprinting, to achieve a variety of design styles, textures and colors.After proper cleaning and maintenance of concrete, sealant (liquid) will be applied on the surface to prevent pollution and skid on the artistic floor surface and strengthen it again.The finished embossed concrete floor is not only very decorative, but also very stable in physical properties.
Construction technology:
1. Before concrete paving, the concrete at the pavement base shall be above 50mm and the concrete at the carriageway base shall be above 80mm;
2. Paving standard concrete. Recommended mix ratio :32.5 424KG cement, 400KG coarse sand, 400KG fine sand, 1100KG gravel (melon seed pieces), 185-195kg water;
3. After the cross vibration of the plate vibrator, cross pulping shall be carried out with iron rollers.
4. Leveling with a leveling ruler and bleeding treatment, and leveling the concrete surface with manual iron plate before the initial setting;
5. Evenly spread 1/2 of the standard dosage (4.5kg/㎡) of the euro color hardener on the surface of the concrete in the initial setting stage;
6. After the hardening agent is dampened and wet, make a leveling and finishing with a manual iron plate or a large spatula. Do not overshovel and wipe the concrete surface, which will lead to the surface water and weaken the color;
7. Apply the remaining hardener to the unevenly spread area for the first time, and wait for the second time after the shade is wet;
8. In the case that the surface is dry without obvious moisture after the initial setting of the hardener, it is necessary to spread the Eolinized demodulation powder (standard dosage is 0.15kg/m2) after pressing the die.
9. After the concrete embossed floor is completely dried and solidified for at least 3-7 days, trim the edges and cut the expansion joints, and wash the cement slurry generated during the cutting;
10. Clean the surface with water or detergent. The cleaning and brushing surface must ensure the same level of cleaning throughout the floor, or it will cause different shades of color on the floor;
11. After the surface of the washed floor is dried, it is coated with a glossy curing agent to enhance the anti-pollution and anti-skid performance of the pressed floor surface. The finished hardened and pressed floor surface is not only very decorative, but also very stable in physical properties.
