The present invention belongs to the technical field of energy consumption and vibration reduction of assembled building structures, and provides an energy-consuming connecting device for a prefabricated assembled wall. The present invention provides a normal connection function between walls, and also has the functions of energy consumption and vibration reduction. A used viscoelastic material can provide energy consumption and weaken the cold and hot bridge effect, which is beneficial to building thermal insulation. Meanwhile, the energy-consuming connecting device for the prefabricated assembled wall can be connected with a prefabricated wall in advance, which can be carried out at the same time as the wall is inserted during construction, thereby effectively increasing the construction efficiency. Through the design of clamping groove devices, the wall can be connected firmly and reliably while generating displacement and consuming energy. A multi-segment fixing plate is used to replace full-length arrangement to save the steel.

The pressure-sensitive light and shadow imaging system is comprised of carrier medium (), inductive surface (), photo source (), photocell () and imaging surface (), wherein the said carrier medium () is set on the top of the pressure-sensitive light and shadow imaging system, and the lower end contacts with the inductive surface () whose lower end is closely integrated with upper surface of the photocell (). The imaging surface () is set underneath the photocell (). Texture substance () contacts the carrier medium (), which can form the pressure-sensitive image. The image can reflect the pressure distribution of the substance and compression sequence. With the processing method of footprint image formed by such pressure-sensitive light and shadow imaging system, several single-frame footprint images are processed as a complete footprint image containing all footprint features, which can eliminate background noise.
