[0026] Referring to Figure 1 , Figure 2 and Figure 3 , a kind of energy dissipation node structure between outer shear wall and high connecting beam, wherein high connecting beam 2 includes high connecting top beam 21 and high connecting bottom beam 22, high connecting top beam 21 is arranged at the top of high connecting bottom beam 22, high connecting top beam 21 includes reinforcing mesh 211 and concrete 212, reinforcing mesh 211 is located inside concrete 212, and reinforcing mesh 211 is extended from the bottom end of high connecting top beam 21, reinforcing mesh 211 extended from the bottom end of high connecting top beam 21 is arranged in high connecting bottom beam 22 and is fixed.
[0027] Referring to Figure 4 and Figure 5The reinforcing mesh 211 comprises a plurality of bent bars 2111 and a plurality of vertical rebars 2112. The plurality of bent bars 2111 are arranged horizontally and transversely, the plurality of vertical rebars 2112 are arranged horizontally and longitudinally, the plurality of bent bars 2111 are evenly distributed along the length direction of the vertical rebars 2112, the plurality of vertical rebars 2112 are evenly distributed along the length direction of the bent bars 2111, and the bent bars 2111 and the vertical rebars 2112 are fixed by iron wires after abutting each other. The energy dissipation joint structure arranged between the high continuous top beam 21 and the outer side shear wall 1 comprises an extruded sheet 3 and a plurality of spring dampers 4. The stiffness of the spring dampers 4 is determined according to the size of the continuous beam obtained by the structural calculation model software. The extruded sheet 3 is fixed between the outer side shear wall 1 and the high continuous top beam 21, and the two side surfaces of the extruded sheet 3 abut the outer side shear wall 1 and the high continuous top beam 21 respectively. The bottom end of the extruded sheet 3 abuts the top end surface of the high continuous bottom beam 22. The extruded sheet 3 arranged between the high continuous top beam 21 and the outer side shear wall 1 has a good buffering effect, which can more effectively utilize the wall limb deformation to achieve energy dissipation and seismic reduction, and reduce the stress level of the high continuous beam 2 to avoid damage.
[0028] The plurality of spring dampers 4 are arranged obliquely, one end of each spring damper 4 is arranged in the concrete 212 and fixed to the bent bar 2111, and the other end of each spring damper 4 is arranged through the extruded sheet 3 and fixed in the outer side shear wall 1.

The plurality of frame steels 2111 are uniformly distributed along the length direction of the vertical steel bars 2112.

Finally, the concrete 212 is poured between the two extruded plates 3, so that the steel mesh 211 and the concrete 212 form the high continuous top beam 21 together. The energy dissipation node structure arranged between the outer shear wall 1 and the high continuous beam 2 is simple to install and convenient to construct, the plurality of spring dampers 4 can dissipate the energy of the reciprocating deformation of the outer shear wall 1 and the high continuous beam 2, greatly increase the energy dissipation capacity of the whole structure without reducing the elastic recovery capacity of the outer shear wall 1 under the action of horizontal force, and have the characteristics of small damage and easy and fast repair after a large earthquake.
