Origin of formwork support system

Building formwork support is only available after concrete pouring. It is a kind of cast-in-place concrete support used in housing construction. It can be made of different materials. Traditionally, it is made of wood and bamboo, which is also formed by the history of architecture. It has many uses, such as columns, girders, wallboards, etc.
Building formwork support has been developed for many years now. The first formwork support is mainly made of wood or bamboo, but there are many disadvantages. It will be limited by the length of the material itself and the temperature and humidity, so the height and length cannot be adjusted. Moreover, the splicing workload is very large, resulting in the low efficiency of construction, the waste of materials, the waste of resources, and the unattractive finished wall, which requires secondary plastering.
In 1908, the United States first used steel formwork, while China was still in the Guangxu period of the Qing Dynasty. Most of the buildings were still wooden frame structures like handicraft workshops, and a small part of them were introduced with brick-wood composite structures. The steel formwork was quickly introduced to other countries. After the 1930s, the steel formwork was introduced to Japan and began to be widely used in the 1950s. There are several types of steel formwork, such as all-steel large formwork, light steel formwork and composite steel formwork.
Today in China, the construction formwork support technology has made great progress, and the material has been greatly improved. The composite structure supported by rigid formwork is used. The biggest advantage of this material is that it has strong scalability and can be reused. It is widely used in different landforms and geological conditions.
There are many different types of supports used for building formwork support. Generally, they will be divided into different types according to different materials. The first category is the traditional practice, that is, the wooden support frame. All materials used for support in this type are made of wood. The second category is the formwork support system for tall buildings. This is more complex, because it is mainly used for buildings with higher height and larger scale. The third category is the rigid building formwork support system, which is more common in current buildings. The materials used are made of steel and have the unique performance of scalability. So let's focus on this.
The material used for the support of the new type of rigid building formwork is high-performance cold-rolled steel. This material has many advantages, such as corrosion resistance, relatively large elasticity, and strong and not easy to deform. It has many characteristics, the first is; The connection mode is flexible and simple, and the structure is stable. The second point is that compared with the wooden structure, it is more precise and solid. The third point is to save labor, time and safety. The fourth point is that no wood material is used, so the product can be reused, so the construction cost will be greatly reduced.
