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.

Method for making a wall with the aid of drywall panels (1, 1a, 1b) and a background (2, 12, 25), wherein the drywall panels are provided with edge coupling profiles (3, 4, 6, 13, 14, 16) on their edges, which are arranged to be secured to the background and, subsequently, coupled to each other. The drywall panels may also be provided with a rear coupling profile (24). The drywall panels can be hooked together or coupled to each other by means of transverse sliding. The edge coupling profiles may also comprise anti-adhesive extensions (31), forming anti-adhesive edge areas (32) at the front side of the drywall panel on which stucco mass does not adhere. The measures according to the invention are intended to provide drywall panels which, after use, can be disassembled easily and cleanly so that the drywall panels can be reused as drywall panels, resulting in that the environment is not burdened with gypsum waste caused by damaged, broken and destroyed drywall panels.
