It is further preferred that first shear stud is welded to connect with reinforcement by connection steel plate, it is implanted into the length of frame column
Meet 25 times of bar diameters, the length of the short shear stud is 100mm, between the long shear stud and short shear stud
Spacing is 200mm.
Preferably, second shear stud resists including the vertical beam of the column shear stud and Vierendeel girder vertical with frame column
Peg is cut, the length that second shear stud is implanted into respectively in the frame column and Vierendeel girder meets 10 times of bar diameters, outside
Leakage length is 150mm.
Preferably, whole reinforcing joint is formed after the reinforcing inside modules casting concrete.
The reinforcing joint of the utility model is combined using section-increased method and reinforcement by sticking of sheets, can not only improve node
Stress performance, while the plastic deformation ability of node can also be significantly improved, enhance the energy dissipation capacity of node, while can realize
Frame joint is persistently constrained, the shear-deformable of joint cores is reduced, increases overall stiffness, improves the shock resistance of node
Can, there is preferable application prospect.
