die and Mold application in CONSTRUCTION
In the construction industry, building formwork is more commonly used.
The common formwork can be divided into steel formwork, plastic formwork, wooden formwork and aluminum formwork. Formwork is an important mold for house molding. Formwork is a tool used to maintain the shape of concrete when grouting concrete. It is applicable to beams, columns, floors or walls. Formwork is almost used for building houses. Among them, the wooden formwork is the most widely used formwork type.
Template development:
In the early days, there was no choice but wood molds, which were generally made of pine and fir wood. They could be reused 4 to 8 times according to usage habits. They had to be oiled and maintained. Compared with other templates, the durability of wood molds was really not very good. Well, the number of reuses is not large, and many wooden forms become waste at the end of the project, so reusable steel formwork was developed later.
According to local conditions, create different values of templates:
No matter what kind of formwork material is used, there are suitable places for use. Generally, the vertical wall of buildings should speed up the construction period. The use of plastic formwork or aluminum formwork can really bring benefits, and it can also keep the site clean and avoid secondary removal and reduce waste. production. The wood formwork also creates a natural wood grain concrete surface. The formwork market has more and more choices, and it is expected that the construction environment and safety will continue to be improved in the future.

- Wooden Mold: The wooden formwork also has many advantages in construction. For example, the special shape of the wooden formwork can be cut to solve the problem on site, and the wooden formwork does not require much pre-work, so it can cope with the ever-changing shapes. If the strength is insufficient, it can be directly connected to the angle Nailed together for strength, it is the easiest formwork material to obtain.
- Steel Mold: Although the steel formwork has the advantages of repeated use and environmental protection, the weight is too heavy. If the steel formwork is transported manually, it will be more labor-intensive. Moreover, the cost of steel formwork is extremely high, so unless bridges, tunnels, etc. or special projects, steel formwork is rarely used.
- Plastic Template: The price of plastic formwork is about 4-5 times that of wooden formwork. The characteristics of plastic formwork are ultra-light weight, not afraid of water, reusable, no need to use release agent, formwork is easy to maintain, and the concrete after molding is smooth and beautiful. The plastic template can be reused and has the characteristics of transparency and light transmission. The finished wall is smooth and flat, but the recycling of plastic waste is a problem. Just like the plastic bottle can be recycled, it needs to be processed by the manufacturer before it can be recycled. The environmental recycling cost is higher than the manufacturing cost. still high. However, the plastic formwork does not replace the wooden formwork, because the engineering habits are not easy to change. The people who use the plastic formwork use the wooden formwork for construction. waste and increase engineering costs.
- Aluminum Formwork: The advantage of aluminum formwork is that its weight is lighter than that of steel formwork, the wall surface after construction is smooth and flat, and tiles can be directly attached to it. Reduce engineering waste. The aluminum formwork needs a special release agent. After the formwork is removed, the iron sheet fixed on the wall must be processed. The special structural design ceiling does not need to be braced after the formwork is removed, which can shorten the construction time. However, due to complex structure and non-standardized design, aluminum formwork cannot be fully applied.
