Basement of basement expansion joint node construction and applied structure

The utility model discloses a basement of basement expansion joint node construction and applied structure, the node construction include expansion joint and a plurality of speed lock, each speed lock arranges on same horizontal plane with the direction with the expansion joint quadrature all that the locking speed of each speed lock all approaches the relative movement speed safety threshold between the roof of expansion joint both sides, when the relative movement speed between the roof of expansion joint both sides is less than locking speed, the structural capacity at the equal much lower than expansion joint of damping force that each speed lock produced, the relative movement speed between the roof of expansion joint both sides more than the locking speed time, each speed lock produces enough big damping force respectively for the roof of expansion joint both sides is through each speed lock rigid connection. The utility model discloses can effectual improvement basement and structural reliability, the protection expansion joint of bottom surface building avoid receiving the damage under horizontal earthquake load and/or wind loading.
