In order to solve the problems of the technologies described above, the utility model is achieved in that
A connected node for prefabricated assembled concrete beam column, is characterized in that: it comprises a prefabricated post, two precast beams, three built-in fittings and at least six pieces of junction plates;
Middle part laterally pre-buried first built-in fitting of described prefabricated post, the first built-in fitting runs through prefabricated post, and the two ends of the first built-in fitting are stretched out from prefabricated post both sides, and is provided with longitudinal reinforcement and stirrup;
Described two precast beams inside pre-buried second built-in fitting and the 3rd built-in fitting respectively, the other end of two built-in fittings stretches out in precast beam;
Two ends respectively with the second built-in fitting of the first built-in fitting, the external part of the 3rd built-in fitting are connected;
Be welded with one piece of riser in described two precast beams, one end of described second built-in fitting and the 3rd built-in fitting is welded to connect with the one side of this riser respectively, and the another side of riser is welded with reinforcing bar up and down in two precast beams and straight dowel.
The connected node of described prefabricated assembled concrete beam column, it is characterized in that: described three built-in fittings are all for splicing by angle steel and batten plate the truss made, connected by batten plate between the outside of top and seat angle, connect with junction plate between angle steel respectively and the second built-in fitting at the first built-in fitting two ends, the angle steel of the 3rd built-in fitting external part, and fix with high-strength bolt.
The connected node of described prefabricated assembled concrete beam column, is characterized in that: the junction of described first built-in fitting and the second built-in fitting, the 3rd built-in fitting is provided with stirrup.
The beneficial effects of the utility model are: break away from the cast-in-place old pattern of node, prefabricated post and precast concrete beam are reserved position by the direct assembled connection of high-strength bolt, arrange special built-in fitting in addition and solve connection stiffness mutation problems.This connected mode is simple and reliable, economic and practical, and both can meet the overall Aseismic Reliability of system, abandoned again Site Welding, construction operation efficiency, safety are obtained for larger raising.
Also there is following advantage:
Construction rapid and convenient: connects with high-strength bolt and replace welding, construction technology is easy, eliminates welding detection operation, can accelerating construction progress;
Structural system is safe and reliable: nonlinear deformation is concentrated on join domain, and other parts of structure keep elasticity, and the safety of node type of attachment is high.Ultimate bearing capacity of joints and cast-in-place node are quite even better than cast-in-place node, and ductility and energy absorption capability are all better than cast-in-place node;
Adopt truss form, reduce rigidity sudden change, improve bearing capacity, shaped steel arranges shear stud, solve steel work and concrete junction shearing resistance problem;
Construct general: than sleeve or slurry anchor connection mode, the present patent application adopts conventional high-strength bolt to connect, and concrete structural system and steel structure connection mode are organically blended, design and construction is comparatively convenient, quality control is also easy to realize with examination, has stronger versatility and promotional value.
