Description

Internal corner template

This creation is about aluminum alloy formwork for buildings, especially the inner corner formwork that can be connected.

During the construction of a building, concrete is poured as one of the main items such as floors, walls, beams and columns. Traditional construction methods mostly use wooden formwork, and the wooden formwork is fixed through nails, wires and other metal accessories to form the inner and outer walls. Concrete can be poured into this section, and the shape of the concrete can be maintained through the aforementioned internal and external walls. After the concrete dries and solidifies, it forms the walls, columns, beams, etc. of the building. Since the production of wooden formwork requires a large number of felled pine, fir, etc., it can only be formed after cutting, whole product and assembly. Since the number of uses of wooden formwork ranges from about 4 to 8 times, the durability of wooden formwork is not very good. ideal.

The traditional wooden formwork used for grouting is a very unenvironmentally friendly consumable. When building interior and exterior walls, a large number of nails, iron wires and other metal accessories are needed to fix the wooden formwork. The wooden formwork also needs to be refinished according to the shape and size of the building. Secondary exterior processing (sawing, drilling), resulting in cutting wood chips at the construction site, nails and wires after dismantling are engineering waste, and roofs and wires after dismantling are dangerous goods if they are not cleaned up in time. Construction workers are at risk of puncturing horns while walking.

Since the production cost of wooden formwork accounts for 20% to 30% of the cost of concrete structure projects, and the convenience of obtaining wooden formwork, it has always been the mainstream factor for large-scale adoption in the construction industry. Since the use of traditional wooden formwork requires the selection of appropriate sizes on site, the use of nails of different lengths and the placement of nails, in order to securely splice and combine the wooden formwork, these technical requirements are extremely high, and the number of practitioners entering this industry has been significantly reduced. Coupled with the revision of laws and regulations in various countries, the promotion of green energy buildings, and the improvement of environmental protection concepts such as carbon emissions, relevant industries have developed plastic formwork, steel formwork, and aluminum alloy formwork, providing construction companies with more choices for construction.
