The invention provides a novel assembly type concrete beam column joint. The novel assembly type concrete beam column joint mainly comprises a fabricated column, a fabricated beam, embedded angle steel, anchor bars, pressure-bearing steel plates, an embedded steel plate, profile steel and a beam tensile bar. Embedded angle steel is embedded in the two sides of the upper portion of the intersecting joint of the fabricated column and the fabricated beam. The profile steel is embedded in the lower portion of the joint of the fabricated column. The parts, beyond the fabricated column, of the two ends of the profile steel are profile steel covered brackets. The pressure-bearing steel plates are welded to the profile steel covered brackets at the two ends of the profile steel correspondingly. The three anchor bars penetrating through the fabricated beam from bottom to top are welded to the parts, close to the 1 / 3 position of the end of the fabricated column, of the pressure-bearing steel plates. The embedded angle steel is connected with the anchor bars in a welded mode. The beam tensile bar is connected with the embedded steel plate at the lower end of a notch of the fabricated beam in a welded mode. The embedded steel plate is connected with the profile steel in a welded mode. The novel assembly type concrete beam column joint is novel in process, reasonable in stress, good in integrality, clear in force transmission, simple in structure, safe, reliable and capable of saving materials.
Description
technical field [0001] The invention belongs to the field of novel joints of building structures, in particular to a novel assembled concrete beam-column joint. Background technique [0002] Prefabricated concrete buildings refer to concrete structure buildings that are designed and constructed based on factory-produced concrete prefabricated components through on-site assembly. Prefabricated concrete structures are being rapidly popularized and applied due to their advantages of energy saving, environmental protection, and little impact on the construction environment. From the point of view of the mechanical properties of the structure, the key issue of the prefabricated structure lies in the reliability of the connection nodes. Previous structural earthquake damages show that the main reason for the failure of most prefabricated structures is the failure of the structural system due to the failure of the beam-column joints. [0003] Prefabricated concrete buildings can b...
