Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing reinforced concrete beams, in particular to a double-rubber steel bar support structure for reinforced concrete beams. Background Art

[0002] Reinforced concrete beams are beams made of steel support and concrete materials. Whether the main reinforcement in the reinforced concrete beam of a construction project is in place directly affects the effective cross-sectional height of the reinforced concrete beam and the magnitude of the force acting on the steel bars, thereby affecting the overall bearing capacity of the beam and the structural stiffness function.

[0003] Publication of patent specification for utility model patent in China CN218541207U A double-rubber steel bar support structure for a reinforced concrete beam is disclosed in the application. Although the application arranges an inner recess, secondary stirrups, outer steel bars and inner steel bars so that when the entire support is manufactured, the outer steel bars can be fixed inside the inner recess by tying with wire, and since the outer steel bars are accommodated inside the inner recess, it is not necessary to take the diameter of the outer steel bars into consideration when the size of the support is determined, thereby reducing the influence of outer steel bars of different sizes on the size of the entire support, so that after the size of the entire support is determined, outer steel bars of different diameters can be selected for installation, thereby improving the flexibility of the manufacturing and construction of the entire support. However, after the steel bar support is fixed, the inner steel bar lacks corresponding fixation. When pouring cement, the inner steel bar is prone to displacement, and there is a disadvantage of poor stability. Moreover, when the steel bars are tied together using stirrups and iron wires, since multiple steel bars are in a dispersed state, it is necessary to initially limit the end faces of multiple steel bars when they are assembled together so that the stirrups can be clamped on the steel bars. There is a disadvantage of a more troublesome assembly process, and it is not convenient to assemble steel bar supports of corresponding sizes as required. Utility Model Content
