Aluminum template factory
Several suggestions and requirements for on-site construction of aluminum formwork factory:
1. When overhanging external scaffolding is used, the installation position map of the cantilever frame should be accurately provided when the aluminum mold is optimized, and the installation time of the scaffolding for 7-10 days shall be reserved. It is suggested that high-rise buildings above 28 floors use intelligent climbing frames with aluminum alloy formwork to improve safety.
2.Distribution machine should not be placed on the surface of aluminum alloy template as far as possible; After the completion of pouring, the level of the floor slab needs to be leveled to control the elevation;
3. Accurate measurement of pay-off line, strict rebar binding requirements, can not affect the installation of the template;
4. Use of release agent: The first two layers use vegetable oil as a release agent, and the second layer uses a water-based release agent to reduce sticking and ensure the quality of the concrete surface.
5. The lower the temperature is, the longer the final setting time of the concrete will directly affect the time of mold removal, and even affect the quality of the mold after demolition. Normally in northern China, aluminum alloy formwork is not used from October to March of the following year. In Huazhong area, mold removal time can be ensured by adding early strength agent. When the average daily temperature is lower than 5°C, it takes 1-2 days to remove the mold. The impact of the region is not great.
