For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] The following will Figures 1 to 3 describe the present utility model in detail.

[0025] A pier body prefabricated external scaffold, including an external scaffold 1. A staircase 101 is arranged in the middle of the external scaffold 1. A connecting block 102 is arranged on one side of the external scaffold 1. A roller 103 is arranged at the bottom of the external scaffold 1. A connecting frame 4 is connected to one side of the external scaffold 1. A connecting rod 2 is connected between the external scaffold 1 and the connecting frame 4. Support rods 3 are connected to both sides of the external scaffold 1. A support assembly is arranged at one end of the support rod 3. The support rod 3 swings along the support group. The connecting block 102 is a convex block arranged in an "L" shape on the opposite side of the external scaffold 1 and the connecting frame 4. Both ends of the connecting rod 2 are fitted into the grooves between one side of the connecting block 102 and the external scaffold 1 and the connecting frame 4. The end of the support rod 3 connected to the external scaffold 1 is hinged.

[0026] First, the external scaffold 1 and the connecting frame 4 are arranged on both sides of the pier body. At the same time, they can be directly pushed for assembly through the rollers at the bottom of the external scaffold 1 and the connecting frame 4. After the height matching the pier body is built in advance as needed, it can be pushed and assembled on both sides of the pier body. At the same time, the external scaffold 1 will be connected to the connecting rod 2 in the connecting block 102 on the connecting frame 4 through the connecting block 102 on one side, so that the external scaffold 1 and the connecting frame 4 can be stably connected on both sides of the pier body.

[0027] At the same time, support rods 3 are also arranged on both sides of the external scaffold 1 to support the side of the external scaffold 1, so that it will not easily tilt and shake.

[0028] Further, the support assembly includes a support block 301, a hinge block 302, a fitting groove 303 and a fitting rod 304. The support block 301 is connected to one end of the support rod 3. The hinge block 302 is arranged on the top of the support block 301. The fitting groove 303 is arranged on the side wall of one end of the support block 301. The fitting rod 304 is arranged on the top of the support block 301. The support block 301 is hinged to one end of the support rod 3 through the hinge block 302 on the top. The fitting rod 304 is arranged in the middle of the hinge block 302. The fitting rod 304 includes a limit rod 3041 and a pin 3042. The limit rod 3041 is a rod body fitted into the groove on the top of the fitting rod 304 through a spring at the bottom. The pin 3042 is connected to the middle of the fitting rod 304. The top of the limit rod 3041 is trapezoid-shaped for cooperation with the fitting groove 303. The pin 3042 penetrates through the fitting rod 304 to connect with the limit rod 3041.

[0029] At the same time, when connecting and supporting the support rod 3, one end of the support rod 3 is hinged to the support block 301 through the hinge block 302 to fit the ground for support. Through the hinge setting of the hinge block 302, the support block 301 can adapt to different inclination angles of the support rod 3, enabling it to always fully fit the ground for support. When adjusting to the angle of the support rod 3, one end of the support rod 3 will deflect along the hinge block 302, thereby applying pressure to the limit rod 3041 connected to the top of the fitting rod 304 through the fitting groove 303. Through the cooperation of the trapezoidal block, when applying pressure, the limit rod 3041 is forced to contract into the fitting rod 304, allowing the support rod 3 to deflect smoothly. When deflecting to a suitable angle and the support block 301 can fit the ground for support, the limit rod 3041 will be fitted into the fitting groove 303 for cooperation due to the reset of the spring, and then fixed by the pin 3042, thereby limiting the deflected angle and preventing it from deflecting easily again. Thus, when the support rod 3 is connected to different positions on the outer frame 1 at different heights as needed, it can flexibly contact and support the ground, avoiding the inclination that is likely to occur during assembly because the prefabricated outer frame is not directly connected to the pier body and is not fixed to the ground.

[0030] The following is the specific implementation process of the present utility model. First, the outer frame 1 and the connecting frame 4 are arranged on both sides of the pier body. At the same time, they can be directly pushed for assembly through the rollers at the bottom of the outer frame 1 and the connecting frame 4. After building the height to match the pier body in advance as needed, it can be pushed and assembled to both sides of the pier body. At the same time, the outer frame 1 will be connected to the connecting rod 2 in the connecting block 102 on the connecting frame 4 through the connecting block 102 on one side, so that the outer frame 1 and the connecting frame 4 can be stably connected to both sides of the pier body. At the same time, support rods 3 are arranged on both sides of the outer frame 1 to support the side of the outer frame 1, so that it will not easily tilt and shake. At the same time, when the support rod 3 is connected for support, one end of the support rod 3 is supported by the support block 301 through the hinge block 302 to fit the ground. Through the hinge setting of the hinge block 302, the support block 301 can adapt to different inclination angles of the support rod 3, so that it can always fully fit the ground for support. When adjusting to adapt to the angle of the support rod 3, one end of the support rod 3 will deflect along the hinge block 302, so that the limiting rod 3041 connected to the top of the fitting rod 304 will be pressed through the fitting groove 303. Through the cooperation of the trapezoidal block, when pressing, the limiting rod 3041 will be forced to shrink into the fitting rod 304, so that the support rod 3 can deflect smoothly. When it deflects to a suitable angle and the support block 301 can fit the ground for support, the limiting rod 3041 will be fitted into the fitting groove 303 for cooperation due to the reset of the spring, and then fixed by the pin 3042, so as to limit the deflected angle and prevent it from deflecting again easily. Thus, when the support rod 3 is connected to different positions on the outer frame 1 at different heights as needed, it can flexibly contact and support the ground.

[0031] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
