[0019] The utility model will be described in detail below. Figs. 1 to 3

[0020] A complex curve steel shell assembly type construction platform, comprising a platform plate 1, the top of the platform plate 1 is provided with a guardrail 101, the bottom of the platform plate 1 is provided with a foot support 102, the bottom of the platform plate 1 is provided with a displacement groove 103, the displacement groove 103 is connected with a fitting block 2 at the bottom, the top of the fitting block 2 is provided with a displacement block 201, the fitting block 2 is connected with the displacement groove 103 through the displacement block 201, the platform plate 1 is provided with several mutually welded settings, and the foot support 102 is welded and arranged together with the bottom of the platform plate 1.

[0021] First, the foot support 102 is connected with the positioning point of the cable-stayed bridge tower steel shell outer wall, then the top of the foot support 102 is kept parallel by adjusting according to the arc or protrusion of the steel shell outer wall, then the prefabricated platform plate 1 is placed on the foot support 102, and then welded together for connection, several platform plates 1 are sequentially connected on the foot support 102 for welding, and a assembly type construction platform is formed by splicing and welding, so that the arc and special-shaped protrusion of the steel shell outer wall can be adjusted and built, and different steel shell towers can be better matched.

[0022] ​Further, the displacement groove 103 comprises a fitting rod 1031 arranged in the middle of the displacement groove 103, the fitting block 2 further comprises a limiting block 202 and a fitting groove 203, the limiting block 202 is arranged on both sides of the displacement block 201, the fitting groove 203 is arranged in the middle of the fitting block 2, the limiting block 202 is a protrusion on both sides of the displacement block 201, and the limiting block 202 is matched with the grooves on both sides of the middle of the displacement groove 103, the fitting groove 203 is a groove matched with the fitting rod 1031, and one end of the fitting groove 203 is connected with the fitting rod 1031 through a spring.

[0023] When the platform plate 1 is installed and built, if the outer wall of the steel shell is arc-shaped or has a protrusion, the steel shell cannot be completely fitted with the platform plate 1, and a gap will be formed between the steel shell and the platform plate 1 in some positions. Therefore, when the platform plate 1 is connected, the fitting block 2 on one side is forced to abut against the outer wall of the steel shell, and the fitting block 2 will move inwards in the displacement groove 103 through the displacement block 201 on the top when the fitting block 2 is forced. A plurality of fitting blocks 2 arranged in series will change the shape of the steel shell outer wall by different displacement distances to form a groove matched with the shape, so that there is no gap between the platform plate 1 and the steel shell outer wall, and then the platform plate 1 is welded and fixedly connected with the foot support 102, avoiding the construction personnel stepping on the void or the construction tool falling.

[0024] At the same time, the displacement block 201 will be limited and connected with the grooves on both sides of the middle of the displacement groove 103 through the limiting blocks 202 on both sides when the displacement block 201 is displaced, so that the fitting block 2 is more stable through the connection of the displacement block 201, and the spring connection of the fitting groove in the fitting block 2 and the fitting rod 1031 makes the fitting block 2 generate a resetting force after contraction, which can abut against the outer wall of the steel shell and will not be easily affected and shrink by itself.
