Description

Technical Field

[0001] The utility model belongs to the technical field of concrete structures, and in particular relates to a splicing node of a spliced ​​concrete component. Background Art

[0002] Precast concrete components are a type of building material. Existing precast concrete components have poor waterproofing effects. When subjected to water erosion, the strength of the components themselves will be reduced, while the corrosion of the internal steel bars will be accelerated. Moreover, since precast concrete components usually only have steel bars to enhance their strength, the effect is poor, resulting in low strength of the precast concrete components and prone to damage. At the same time, since the structural details of the connection nodes when two groups of precast concrete components are connected together are not perfect, the assembled building has poor stability. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a splicing node of a spliced ​​concrete component.

[0007] Furthermore, the positioning groove is arranged in a conical shape, and a conical positioning portion embedded in the relative positioning groove is formed at the end of the splicing plate.

[0008] Furthermore, the first connecting member includes a plurality of first connecting stirrups spaced apart between the two first panels and a first reinforcing stirrup connected between the plurality of first connecting stirrups.

[0009] Furthermore, a first connection block connected to the end of the first connection stirrup is formed on the opposite surface of the first panel and the other first panel, and the first connection block is formed with a first connection groove extending inwardly for the end of the first connection stirrup to be embedded.

[0010] Furthermore, the second prefabricated concrete component includes two second panels disposed opposite to each other vertically, a second connecting member connected between the two second panels, and a second concrete beam body disposed between the two second panels, and the ends of the second panels are bent inwardly to form the connecting legs.
