Abstract

The invention discloses an assembled mortise and tenon bracket type beam-column joint connecting device. The device comprises a prefabricated column and a prefabricated beam, wherein a plurality of L-shaped extending steel bars with hooks are pre-embedded in the prefabricated column; a hidden bracket is fixedly arranged on the side face of the prefabricated column; the face, away from the prefabricated column, of the hidden bracket is an inclined face; a right-angle triangular prism groove is formed in the inclined face; a bracket pre-embedded L-shaped steel plate is pre-embedded in the hidden bracket; a notch matched with the hidden bracket in shape is formed in the lower portion of the side, close to the prefabricated column, of the prefabricated beam; a right-angle triangular prism protruding block is arranged on the connecting face of the prefabricated beam and the inclined face of the hidden bracket; and the prefabricated beam is provided with reserved steel bar holes and steel plate inserting grooves matched with the bracket pre-embedded L-shaped steel plates. According to the invention, the hidden bracket, the shear resistance is provided while the pre-embedded L-shaped steel plates and the column steel bars are anchored into the prefabricated beam, and the shear strength of a beam-column joint can be effectively improved.

Description

technical field [0001] The invention relates to a prefabricated mortise and tenon corbel-shaped beam-column joint connection device, which belongs to the technical field of prefabricated beam-column joint construction. Background technique [0002] Prefabricated is an important development direction of the construction production mode in the modernization process of the construction industry. It is to prefabricate building components such as beams, columns, floors, etc. in the factory, and splicing the prefabricated components at the construction site. The prefabricated building production mode is more efficient and has less environmental impact than the traditional cast-in-place concrete production mode. At present, the beam-column joint connection method of the prefabricated concrete frame structure still has the following shortcomings in terms of construction technology and construction quality: [0003] (1) Due to the design of the prefabricated beam-column wet joints, ...
