Assembly type building design main body connecting structure

The utility model relates to the field of fabricated buildings, and discloses a fabricated building design main body connecting structure. The inner walls of the two sides of the reinforcing box are fixedly connected with sliding sleeve rods, the sliding sleeve rods are sleeved with two springs, the tail ends of the two springs are fixedly connected with movable rubber sleeves, the top ends of the movable rubber sleeves are provided with supporting columns, and the ends, away from the movable rubber sleeves, of the supporting columns are fixedly connected to the inner walls of the tops of the connecting cross beams. When a connecting cross beam is impacted, the connecting cross beam can compress a supporting column downwards, so that the supporting column and a movable rubber sleeve are pushed to move outside a sliding sleeve rod, and the movable rubber sleeve can move left and right outside the sliding sleeve rod; and friction is generated between the movable rubber sleeve and the sliding sleeve rod, so that
