Characteristics of hollow plastic building template

The building template is a temporary supporting structure, which is made according to the design requirements, so that the concrete structure and components are shaped according to the specified position and geometric size, maintain their correct position, and bear the weight of the building template and the external load acting on it. The building templates are mainly divided into wooden building templates, steel-wood building templates, building plywood, steel bamboo building templates, plastic building templates, etc. Plastic and steel, wood and cement are collectively called the four major building materials. The energy consumption of production and application of building plastic products is much lower than other materials. Plastic formwork is an energy-saving and environmentally friendly product. It is a new type after wood formwork, combined steel formwork, bamboo-wood glued formwork, and all-steel large formwork. Replacement products. Can completely replace the traditional steel formwork, wood glued formwork, square wood, energy saving and environmental protection, and low amortization cost. As the country vigorously promotes the development of energy-saving and low-consumption products, as well as the development of my country's plastic industry and the improvement of the performance of plastic composite materials, various new plastic templates are also being continuously developed and born. The surface of the plastic formwork is flat and smooth, which can meet the requirements of the clean concrete formwork. The demoulding is fast and easy. The flatness error of the plate is easy to control. The thickness is uniform. The thickness tolerance can be controlled to within ±0.2mm. Good water resistance, long-term immersion in water does not delaminate and rot, the material's water absorption expansion rate is less than 0.05%, and the plate size is very stable. It can resist acid, alkali and weather resistance. It can be used normally at temperatures from -20℃ to 60℃, without affecting the use effect, and it has strong durability. It is more suitable than steel formwork in coastal areas, underground projects, mines, sea dams, drainage and other projects in China. It has strong plasticity, allowing designers to have a lot of free design space. According to the design requirements, different mold forms can be used to produce templates with different shapes and different specifications. The template surface can be made into decorative patterns to allow template engineering and decorative engineering to be combined. This is not easy to do with other material building templates.
