The steel back bar reinforcement system is a new type of structure with high-strength bolt connection as the main load-bearing member. It is built by modifying the original concrete column foundation, wall body and beam plate.

Main characteristics of steel back ridge reinforcement system

The main and secondary keels made of cold-rolled steel are used to replace the traditional wood square steel pipe formwork reinforcement system.

(1) The main and secondary keels of the steel back ridge are all steel structures, which are more rigid than wood and steel pipes, with small deformation and stable and reliable reinforcement.

(2) the length of the main and secondary back edges of the steel back edge formwork reinforcement system shall be made into standard components according to the architectural design modulus. During construction, assembly and combination shall be carried out according to specific needs. For individual parts that do not conform to the modulus, they can be adjusted through expansion joints. Its flexible size is suitable for the needs of various building structure sizes, and the product combination is convenient. For the parts of heterosexual structures, the reinforcement problems in construction can also be solved through the customized processing of heterosexual members. It can be reused, with many turnover times, low amortization cost and obvious economic effect.

(3) the main and secondary keels of the steel back ridge are rolled from thin-walled steel, with light weight, small volume, small land occupation, easy handling and turnover, and convenient transportation.

(4) the steel back ridge members are standardized and modular, with simple accessories, strong applicability, uniform specifications, stereotyped connection, simple and reliable.

(5) save a large amount of wood, protect resources, and do not need to be processed on site, and do not generate a large number of corner wastes, which is suitable for green and environmental protection construction. The steel back reinforcement system uses steel instead of wood, and the recovery and reuse rate are significantly improved.

(6) the main and secondary keels and accessories of the steel back edge formwork reinforcement system are made of profile steel, and the material section size is the same. The original point contact between the primary and secondary keels is changed to the current surface contact. The contact surface is increased and the stress is more uniform. The materials of the main and secondary keels are the same and the deformation is consistent, thus improving the strength and rigidity of the reinforcement of the formwork as a whole. The construction quality error is controllable, and the forming effect of concrete components is better. The cost of later chiseling and plastering is reduced, and the economic effect is remarkable.

(7) the steel back edge formwork reinforcement system has strong applicability and is suitable for the reinforcement of various shear wall, beam, column and floor formwork.

(8) the stereotyping and standardization of the tools of the steel back edge formwork reinforcement system greatly reduce the operation difficulty of the workers, and the technical level of the workers is not high. It can also standardize the operation habits of workers, keep the site clean and tidy, and realize safe and civilized construction on the premise of ensuring the project quality.
