1. What is an aluminum template?
The full name of aluminum formwork is aluminum alloy formwork for building, which is a new generation of formwork after wood formwork and steel formwork. Aluminum formwork is designed according to modulus, extruded by special equipment, and can be freely combined according to different structural dimensions. The design, development and construction application of aluminum formwork is a great development in the construction industry. The application of aluminum formwork system in construction industry has improved the construction efficiency of construction projects, including greatly saving building materials and manual arrangement.
Second, what are the disadvantages of aluminum formwork building?
1. The first three walls have poor aesthetics.
Because the aluminum alloy formwork forms a whole after assembly, it is not easy to ventilate. During the pouring process, the formwork reacts with the concrete. If the concrete is not vibrated enough, bubbles will easily appear on the wall surface, and the release agent is not in place, which will easily lead to peeling and other phenomena.
2. It cannot be modified after installation.
In the design of aluminum alloy formwork, the structural drawings and architectural drawings that need to be constructed must be very accurate, so the technical work of the project is very demanding, and the design work before construction should be done well in advance. After aluminum formwork is processed, it cannot be modified during field installation. If there is any design change, it is necessary to communicate with the manufacturer in advance, deepen the design and processing again, and then transport it from the manufacturer to the construction site, where the wooden formwork can be cut at will.
3. The initial investment is relatively large.
Because the unit price of aluminum formwork per square meter is relatively high, the initial one-time relative investment is relatively large. In this process, management should be strengthened, especially the standard plates of aluminum alloy formwork and support rods should be recovered and maintained for use in the next construction site.
4. The skills of construction workers are uneven.
As the aluminum alloy formwork is a new material and new technology in recent years, there are relatively few operators and uneven construction technology, which leads to the construction effect can not be guaranteed.
