This design is well-known to ensure between stair wall that workspace is arranged in safety cabinet because of stair wall reinforcement,The close contact that vertical direction is not in the top of a piece of one side wall of wall form and the ball of wall adhesion acquisition walking but the earth ensure a retention force on the top that horizontal deflection is sitting in wall wall surface be in close contact the side of Ward and wall fixed port have at a pair of supporting members because,It is formed between supporting member and fixing piece and is adhered to the lateral of wall for fixing supporting member,Scaffold is not to be formed and worked among the upper reinforcement staff work of the earth to secure the frame on workspace,Its side for being formed in the workbench stair wall reinforcement for providing a working face for the sake of assurance,It includes a safety rail to prevent the accident declined of worker,It is planned advantageous to improve machinability,Because Sillim is improving efficiency and reliably strengthening reinforcement allows operator's station for workspace by what it was facilitated between the wall of stair. In addition, subject innovation is that operator can be formed a psychological Anxiety and eliminate to safety rail, being used to ensure the safety of operator to have the advantage that during operation can also prevent collision due to carelessness. Particularly, the present invention is the practical construction that design can increase efficiency, and the utilization of the working range of muscle wall can be selectively applied to wall, regardless of the width and width of step.
