A reinforced concrete prefabricated component

Abstract

The invention relates to the technical field of building components, in particular to a reinforced concrete prefabricated component; the adopted technical solution is: a connecting protrusion is provided at the lower end of the prefabricated component body, and a grouting cavity is vertically provided in the middle of the connecting protrusion; A number of connecting ribs are vertically provided in the slurry chamber, one end of the connecting rib extends into the prefabricated component body, and the other end of the connecting rib extends out of the prefabricated component body; the connecting protrusion is provided with a connecting sealing ring, and the A grout overflow cavity is also provided in the prefabricated component body, and the grout overflow cavity communicates with the outside of the prefabricated component body and the grout filling cavity at the same time. In the present invention, under the action of the self-weight of the prefabricated component body, the connecting ribs and connecting protrusions squeeze the concrete mortar in the grouting cavity into the grouting cavity, and the gas and excess concrete mortar in the grouting cavity are discharged to the overflow cavity , can ensure the strength of the connection of the prefabricated component body, and can also avoid the leakage of concrete mortar. It has the characteristics of simple assembly operation, high assembly efficiency, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a reinforced concrete prefabricated component. Background technique [0002] At present, the connection method of prefabricated components of prefabricated concrete buildings / bridges, especially the vertical connection method of vertical components, after technical changes, mainly adopts the connection method of steel sleeve grouting. Among them, the grouting of the steel bar sleeve requires the use of a sleeve with openings at both ends, and a slurry inlet and a slurry outlet are opened on the side wall of the sleeve. A section of the sleeve is embedded in the prefabricated component, and the slurry inlet and outlet of the sleeve The mouth reserved sleeve is located on the outer side of a section of the prefabricated component, and the pre-embedded ribs of the prefabricated component are inserted into the sleeve. During installation, the protruding steel bars of the...
