Energy-consuming connecting device for prefabricated assembled wall

An energy-consuming connecting device for a prefabricated assembled wall, which is of a symmetrical structure and mainly composed of a wrapping steel plate, a viscoelastic material, a grooved steel plate, a first fixing plate, a second fixing plate, a spring, a plate-shaped dowel and an H-shaped steel column;

• the wrapping steel plate is of a “J”-like structure;
• the top of a long edge of the wrapping steel plate is fixedly connected with one side of a wall, and a gap exists between a short edge and an other side of the wall;
• the wrapping steel plate and the wall are fixedly connected lengthwise;
• the viscoelastic material is bonded to an inner wall of the wrapping steel plate and an inner wall of the second fixing plate;
• a long edge of the grooved steel plate is bonded with the viscoelastic material, and two short edges of the grooved steel plate respectively have gaps from the wall and an inner wall of the short edge of the wrapping steel plate;
• a clamping groove is formed on the grooved steel plate in alignment with the plate-shaped dowel;
• one end of the first fixing plate is fixedly connected with the wall, and the other end is fixedly connected with the H-shaped steel column;
• the first fixing plate is not a full-length plate, but a segmented plate;
• one end of the second fixing plate is fixed on the wall, and the other end is opposite to the short edge of the wrapping steel plate;
• the second fixing plate is connected with a short edge of the grooved steel plate through the viscoelastic material, and is fixedly connected with the wall lengthwise;
• clamping grooves are formed on the H-shaped steel column at the plate-shaped dowel, wherein the positions of the clamping grooves on a flange of a single side are mutually staggered, and the clamping grooves on flanges of both sides are symmetrically arranged;
• two flanges of the H-shaped steel column are clamped into the grooved steel plate;
• the plate-shaped dowel is connected with the spring and the spring is fixed with the H-shaped steel column, wherein both sides of the plate-shaped dowel are respectively clamped into the grooved steel plate and the clamping grooves formed on the H-shaped steel column.
