(1) The stiffness of wood and steel pipe is poor, and their mechanical properties are different. When the wood is pressed, it often deforms at the contact point with the steel pipe, leading to die expansion and die running. The construction quality is difficult to be guaranteed, and the large amount of post-treatment and maintenance will affect the construction period and increase the cost.

(2) due to the large deformation of wet expansion and dry shrinkage of the timber, it is easy to warp and crack during the concrete pouring process due to improper treatment, which will lead to formwork expansion, section size bulging, slurry leakage, etc., and poor concrete forming effect on site. In the traditional wood and steel pipe reinforcement construction, the wood and steel pipe are often cut and sawed randomly according to the site conditions, resulting in the remaining wood 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 large amount of wood, which seriously consumes resources. After the use of wood, a large amount of waste will be generated, and the recycling rate and turnover rate are low, and a large amount of leftover garbage will be generated in the field construction, which is not environmentally friendly; The large amount of wood stored on the construction site is easy to cause fire safety hazards.

The traditional wood and steel pipe reinforcement system requires a large number of wood and steel pipe specifications and occupies a large area. The support system built at random leads to chaos on the site and inconvenient passage of personnel, which increases the difficulty of safe and civilized construction management.

(6) the traditional wood square steel pipe reinforcement system requires high technical level of workers. In the form of shortage of highly skilled workers in the current construction market, the high or low level of woodworking technology directly affects the quality and progress of physical projects.

(7) in the construction of the traditional wood square steel pipe reinforcement system, the reinforcement problems of the wall openings, internal and external corners, wall ends, corners and other parts have not been effectively solved, and the reinforcement of the anisotropic parts of the wall columns is even more difficult. It is often laborious and laborious, but the effect of the finished products is not ideal.

Compared with the traditional wood square steel pipe reinforcement system, the steel back ridge formwork reinforcement system has distinct characteristics, mainly reflected in green construction, standardization of components, more turnover times, light and durable, simple operation, fast construction, strong applicability and universality, and good economic effect. Many advantages of the reinforcement system have been recognized by the majority of construction units and enterprises. Many large construction enterprises have vigorously promoted the steel back ridge reinforcement system as a standardized template support system within the enterprise. At present, the construction market requires higher and higher quality standards for the main structure, and the third-party inspection has become a normal. In this form, the application of aluminum formwork support system is more and more, but the investment cost of purchase or lease is very high. Moreover, whether the use of aluminum mold can meet the project cost target should also consider many factors, such as the facade and number of floors of the building structure, whether the later plastering cost can be calculated, the design optimization, and the supply of building materials market. Therefore, in terms of both quality and project cost objectives, the application of steel back edge formwork reinforcement system is a good solution. The technology of steel back ridge reinforcement system is mature, and it is constantly improved according to different needs. It has broad market application and promotion prospects, and plays an important role in the field of construction.
