The new formwork support system has obvious advantages in the field of green building.

First, the circular economy development principle of reduction, reuse, recycling and reduction priority runs through the construction cycle, which can meet various needs of building functions;

Second, the new formwork support adopts standardized design, factory manufacturing, industrial production, assembly construction, comprehensive decoration, information engineering management and comprehensive services, which is a revolution in the traditional construction industry. The new formwork support can also solve the problem of steel overcapacity, protect the ecological environment and benefit future generations.

Traditional wood square steel pipe reinforcement system

(1) There is a big difference between the stiffness of steel pipe and that of wood. When the timber is under pressure, it often deforms at the contact point with the steel pipe, resulting in die expansion, die running and other phenomena. The construction quality is difficult to be guaranteed, and the amount of post-treatment and maintenance is large, which affects the construction period and increases the cost.

(2) Due to the large deformation of wet expansion and dry shrinkage of timber, it is easy to warp and crack due to improper treatment in the process of concrete pouring, which will produce formwork expansion, bulging of section size and slurry leakage, which is easy to cause poor concrete forming effect on site. In the traditional wood square steel pipe reinforcement construction, the wood square and steel pipe are often cut and sawed randomly according to the site conditions, resulting in the remaining wood square and steel pipe can not be reused, which is a serious waste and difficult to control the cost on the construction site. The traditional wood square steel pipe reinforcement uses a lot of wood, which seriously consumes resources. Wood will produce a large amount of loss after use, with low recycling rate and turnover utilization rate, and a large amount of leftover waste will be generated in on-site construction, which is not environmental friendly; A large amount of wood stored on the construction site is easy to cause fire and great potential safety hazards.

(3) The traditional wood square steel pipe reinforcement system requires more specifications of wood square and steel pipe, occupies a large site, and the arbitrarily built support system leads to chaos on the site; Inconvenient personnel access; It increases the difficulty of safe and civilized construction management. The traditional wood square steel pipe reinforcement system requires high technical level of workers. In the current form of shortage of high-tech workers in the construction market, the high and low level of woodworking technology directly affects the quality and progress of physical projects. In the construction of traditional wood square steel pipe reinforcement system, the reinforcement problems of wall openings, internal and external corners, wall ends, corners and other parts have not been effectively solved, and the reinforcement of anisotropic parts of walls and columns (Z, t, L type) is a difficult problem, which is often labor-intensive, but the effect of finished materials is ignored.
