Example 2

[0025] Figure 1-5The utility model shows a steel formwork support structure of an embodiment of the utility model, which includes: two steel pads 1: the top of the steel pad 1 is fixedly connected with a prism column 2 by bolts, the surface of the prism column 2 is sleeved with a hollow cross seat 3, the front and rear sides of the hollow cross seat 3 are provided with holes, the inner cavity of the hole is slidably connected with a straight rod 4, the opposite ends of the two straight rods 4 are fixedly connected with a round head 5, a spring 6 is welded between the round head 5 and the surface of the hollow cross seat 3, the inner cavity of the spring 6 is slidably connected to the surface of the straight rod 4, the opposite ends of the two straight rods 4 are fixedly connected with an expansion panel 7, the expansion panel 7 is located in the inner cavity of the hollow cross seat 3, and the surface of the leg 13 is rotatably connected with a stiffening rod 14.
