Aluminum alloy template and preparation method thereof

Abstract

The invention relates to an aluminum alloy template and a preparation method thereof. The aluminum alloy template raw material comprises the following raw materials in parts by weight: 0.5 to 0.55 part of magnesium, 0.3 to 0.5 part of manganese-copper alloy, 0.05 to 0.1 part of iron, 0.01 to 0.02 part of zinc, 0.04 to 0.06 part of nickel, 0.03 to 0.05 part of beryllium, 0.1 to 0.15 part of silver,0.7 to 0.75 part of silicon, and 97 to 98 parts of aluminum ingot, wherein the amount of copper in the aluminum ingot is less than or equal to 0.2%, and the iron content is less than or equal to 0.2%; the preparation method comprises the steps of batching, smelting, refining, aluminum alloy template die-casting, aluminum alloy template thermal laminating, aging treatment and aluminum alloy template treatment. The hardness and strength of the obtained aluminum alloy template can be effectively improved, the purposes of being sturdy, durable, and many times of turnover are achieved, and the problem of chemical reaction of aluminum alloy and concrete can be solved, the occurrence of bubble holes and floating ash on a wall is avoided.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to an aluminum alloy template and a preparation method thereof. Background technique [0002] At present, it is widely used in the support system of the roof slab, mostly steel pipe fasteners and bowl buckle scaffolding. These systems are independent from the roof slab formwork system and lack integrated design. There are a large number of phenomena such as low construction efficiency, waste of materials and man-hours, and even safety accidents caused by improper support equipment and construction plans, which may cause serious damage. casualty accident. With the construction of large-scale infrastructure in my country, such as highways, railways, urban rail transit, high-rise buildings, super high-rise buildings and large public buildings, the use of aluminum alloy building templates has become increasingly popular. Aluminum alloy formwork refers to the architectural f...

Problems solved by technology

[0003] However, there are still problems in the preparation process of aluminum alloy templates. The melting points of different metals are very different. Therefore, aluminum alloys have a very wide solidification temperature range, which will cause casting defects such as hot cracks, shrinkage cavities, shrinkage porosity, and segregation of the product during solidification. , leading to the decline in the performance of the aluminum alloy formwork, resulting in insufficient hardness and strength, thereby reducing the number of uses, and the aluminum alloy formwork has higher requirements for its own hardness. If the hardness is not enough, there will be technical defects such as gaps and deformation, which will endanger the project quality and construction. safety of personnel

Secondly, when the new aluminum alloy formwork is used for the first few times, the surface of the aluminum material will react chemically with the concrete. The concrete surface looks flat, but small air bubbles will appear, which will cause the surface of the concrete to float ash, and the appearance will be poor, which will cause certain damage to the later projects. influences
