description The utility model discloses a construction rack, and relates to the technical field of tunnel construction. The construction rack comprises a rack plate, a cavity is formed in the rack plate, two telescopic plates are slidably connected to the interior of the cavity, side plates are fixedly connected to the telescopic plates, folding protection plates are fixedly connected to the opposite sides of the side plates, n-shaped supporting legs are fixedly connected to the lower surfaces of the telescopic plates, and the supporting legs are fixedly connected to the lower surfaces of the supporting legs. Rollers are arranged on the supporting legs, and a telescopic mechanism is arranged on the frame plate. According to the construction rack, when the distance between the pull rods is reduced, the two telescopic plates are driven to move relatively, at the moment, the overall width of the rack plate is reduced, when the distance between the pull rods is increased, the two telescopic plates are driven to move opposite
