Embodiment 1
[0047] Such as Figure 1-Figure 2 As shown, a beam-column-reinforced in-line joint with reinforced avoidance assembly is composed of a precast concrete composite beam 1 and a precast concrete column 2;
[0048] Precast concrete composite beam 1 mainly includes concrete prefabricated beam 1-1, beam bottom longitudinal reinforcement 1-2, beam stirrup 1-3, longitudinal reinforcement bending point strengthening stirrup 1-4, bending longitudinal reinforcement reinforcement 1- 5. Cast-in-place shear bending reinforcements 1-6 at beam ends;
[0049] Prefabricated concrete column 2 mainly includes prefabricated column 2-1, corner straight reinforcement 2-2, avoidance bending reinforcement 2-3, bending reinforcement strengthening reinforcement 2-4, sleeve 2-5, straight reinforcement bending reinforcement reinforcement stirrup 2-6. Stirrups 2-7 with double-curved ribs, and 2-8 cast-in-place shear-bend reinforcements at column ends.
[0050] The steel bar avoids the precast concrete co...

The invention provides a rebar avoiding fabricated beam and column reinforced linear joint, and belongs to building structure novel fabricated concrete beam and column joints. The rebar avoiding fabricated beam and column reinforced linear joint is composed of a prefabricated concrete superposed beam and a prefabricated concrete column. When an even number of beam bottom longitudinal bars are arranged, one half of the beam bottom longitudinal bars of the prefabricated concrete superposed beam are horizontally bent twice, and the other half of the beam bottom longitudinal bars of the prefabricated concrete superposed beam are not bent. When an odd number of the beam bottom longitudinal bars are arranged, the difference between the number of the beam bottom longitudinal bars bent twice and the number of the non-bent beam bottom longitudinal bars is 1. 2 avoiding bent rebars are arranged at the positions, on every two connecting lines of all square sides, of corner straight rebars of theprefabricated concrete column. A large quantity of joint rebars can be reasonably avoided in the construction process, shear keys in all directions are reasonably arranged on the premise of guaranteeing reasonable avoiding, the bearing force of the joint is remarkably improved, an especially the anti-shearing capacity of the joint is remarkably improved. The joint has the beneficial effects of being convenient to construct, high in construction speed, good in economic effect and the like, components are convenient to produce, all the rebars are avoided, the shear keys are arranged, and factoryproduction is not affected.
Description
technical field [0001] The invention belongs to a novel assembled concrete beam-column joint of a building structure, in particular to an assembled beam-column reinforced in-line joint for steel bar avoidance. Background technique [0002] Prefabricated concrete buildings refer to concrete structure buildings designed and constructed through on-site assembly, mainly based on factory-produced concrete prefabricated components. The assembly methods of components generally include on-site post-casting laminated layer concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting connection, welding, mechanical connection and lap connection of reserved holes. In the 1980s, prefabricated prefabricated large-slab houses, which were popular in my country, had many hidden dangers and defects that affected structural safety and normal use due to poor structural integrity, leakage, and floor cracks, and were gradua...
