Novel assembly type primary and secondary beam connecting node and connection method thereof

Abstract

The invention discloses a novel assembly type primary and secondary beam connecting node and a connection method thereof. The node comprises a primary beam and secondary beams. Two sides of the primary beam are both equipped with secondary beam support tables. The positions where the primary beam is located in the middle positions of the secondary beam support tables are equipped with pre-embeddedbolts. Interiors of the secondary beams are equipped with reserved bolt holes. Positions of the reserved bolt holes match those of the pre-embedded bolts. Back sides of the reserved bolt holes are equipped with fastening nuts. Tops of the secondary beams are equipped with fixed openings. Heights and widths of the secondary beam support tables are the same as the secondary beams. The secondary beam support tables and the pre-embedded bolts are symmetrically arranged. The invention relates to the technical field of assembly type construction. With the novel assembly type primary and secondary beam connecting node and the connection method thereof, production efficiency of an assembly type industry is effectively increased, thereby avoiding bonding of steel bars during connection of the primary beam and the secondary beams and cast-in-situ of concrete during assembly type construction in the current stage. Assembly rate is increased and the assembly type structure is strengthened. Accordingly, the novel assembly type primary and secondary beam connecting node and the connection method thereof drives building industrialization forward.

Description

technical field [0001] The invention relates to the technical field of prefabricated construction, in particular to a novel prefabricated primary and secondary beam connection node and a connection method thereof. Background technique [0002] Beams are frequently occurring components in building structures. In the frame structure, the beam connects the columns in all directions into a whole; in the wall structure, the connecting beam above the opening connects the two wall limbs to make them work together. As an important component of seismic design, it plays the role of the first line of defense. In the frame-shear wall structure, the beam not only plays a role in the frame structure, but also plays a role in the shear wall structure. In the prior art, the connecting piece used to connect the prefabricated composite primary and secondary beams is a hidden corbel , the dark corbel is composed of two parallel rectangular steel plates connected, pads are welded at the botto...
