Description

Technical Field

[0001] The utility model belongs to the technical field of reinforced concrete prefabricated components, and in particular relates to a steel bar positioning structure of a reinforced concrete prefabricated component. Background Art

[0002] Precast reinforced concrete components are commonly used prefabricated parts in construction. Precast reinforced concrete components can effectively increase the construction speed of buildings by independently manufacturing part of the building structure in advance and then installing it. Through standardized manufacturing, the construction speed can be effectively increased. When installing precast reinforced concrete components, the prefabricated steel bars need to be positioned.

[0003] During the use of the existing positioning structure, the steel bars are passed through the inside of the positioning structure, and the steel bars are limited by positioning holes opened in the positioning structure itself. However, due to the lack of a fastening mechanism, the impact force generated by the cement pouring during the pouring operation will cause the steel bars to easily deviate from the designated position, reducing the use effect of the prefabricated components. Secondly, due to the excessive impurities on the surface of the steel bars, if they are not cleaned in time, after the pouring is completed, the impurities may cause an oxidation reaction in the concrete, causing corrosion of the steel bars, accelerating the aging of the steel bars, and directly affecting the service life and structural strength of the steel bars. Therefore, we provide a steel bar positioning structure for reinforced concrete prefabricated components. Utility Model Content
