The Use Of Aluminum Alloy Template On Site Requirements
Feb 23, 2021
When using cantilevered external scaffolding, the device positioning diagram of the cantilevered frame should be provided when the aluminum mold design is optimized, and 7-10 days for the installation time of the scaffolding should be reserved. It is recommended to use intelligent climbing frame with aluminum alloy formwork for high-rise buildings above 28 floors to improve safety.
Try not to place the placing machine directly on the aluminum alloy template surface; after the pouring is completed, the floor plane needs to be leveled and the elevation is controlled; the measuring and laying out must be strictly required, and the steel bar binding must be strictly required, and the formwork device must not be affected; the use of mold release agent: the first two Vegetable oil is used as the release agent for the layer, and the water-based release agent is used for the second layer and above to reduce the sticking of the mold and the appearance of the concrete.
The lower the temperature, the longer the final setting time of concrete will be, which will affect the demoulding time and even the quality of the concrete after demoulding. Ordinary North China area does not use aluminum alloy formwork from October to March of the following year; Central China area can be used with early strengthening agent to ensure the mold removal time, and the average daily temperature is below 5 ℃. It also needs to extend 1~2 days to remove the mold; South China The geographical influence is small.
Before the aluminum alloy formwork is transported to the construction site, organize the relevant personnel of the construction party to stop the acceptance of the trial assembly aluminum formwork system, and then according to the general construction plan of the site, the construction blueprint, and the order of the installation, the classification and households stop packaging and mark the front can be loaded. . The aluminum alloy formwork is transported into the site, and after the on-site inspection and acceptance, it is hoisted to the first-level specification layer to stop the on-site secondary equipment. The technical personnel of the aluminum alloy formwork manufacturer once again stop training and confessions to the technical workers through the first-level equipment.
