Novel prefabricated concrete frame beam-column connection joint

Abstract

The invention discloses a novel prefabricated concrete frame beam-column connection joint. The novel prefabricated concrete frame beam-column connection joint comprises a prefabricated column and twoprefabricated beams symmetrically mounted on the outer walls of two sides of the prefabricated column correspondingly, the prefabricated column is internally provided with two symmetrically-arranged L-shaped steel plates, and one ends of the two L-shaped steel plates are parallel to the ground and both penetrate out of the prefabricated column. The end surfaces of one ends of the prefabricated beams extend into the prefabricated beams and are provided with through holes, and the two prefabricated beams are installed on the outer walls of the two sides of the prefabricated column through one ends of the L-shaped steel plates which are inserted into the through holes. A plurality of fixing holes arranged vertically and equidistantly are formed in the side walls of two sides of the prefabricated beams and the side walls of the two sides of the prefabricated column corresponding to the prefabricated beams. U-shaped insert members are installed and inserted between fixing holes formed in the prefabricated beams and fixing holes which are correspondingly and horizontally formed in the prefabricated column in parallel. The novel prefabricated concrete frame beam-column connection joint has high comprehensive strength and can improve the stability between the beams and the column.

Description

Technical field [0001] The invention relates to the field of construction technology, in particular to a novel assembly type concrete frame beam-column connection node. Background technique [0002] In the process of installation of precast beams and precast columns in the construction process, metal materials such as steel plates or steel bars are often used to weld or bolt the precast beams on the precast columns to achieve the fixed installation of the precast beams. However, the precast beams and precast beams Usually, if the column is directly welded, it will lead to the disadvantages of poor integrity and poor seismic resistance at the connection node of the precast beam and the precast column. Therefore, a design that can connect the precast beam and the precast column into a whole, improve the overall stability of the structure, and connect the nodes The prefabricated frame structure that plays the role of load transfer is particularly important. Summary of the invention...
