[0028] The working principle of the adjustable-angle staircase formwork system provided by the present utility model is as follows:
[0029] During use, first, the bottom formwork 21 is supported and positioned by the support frame 1. By adjusting the height of the support frame 1, the slope angle of the bottom formwork 21 can be adjusted. Then, the side formwork 22 is horizontally and vertically erected at the edge positions at both ends of the surface of the bottom formwork 21. Then, the step formwork 51 is inserted into the holes reserved in advance on the side walls of the side formwork 22 through the sleeves fixed at both ends, so that it is supported between the two side formworks 22. Then, the clamping block 43 is clamped on the top side wall of the side formwork 22 according to the position of the step formwork 51, so that one end of the clamping block 43 abuts on the surface of the step formwork 51. Then, the position of the positioning plate 41 is adjusted, and the positioning pin 42 is threaded through the side walls of the positioning plate 41 and the side formwork 22, so that it is threadedly connected with the step formwork 51 through the screw hole 54 until the hexagonal card slot 44 at one end is clamped on the side wall of the hexagonal column 52, so that the position of the step formwork 51 is fixed by the positioning pin 42. At the same time, the positions of the clamping block 43 and the positioning plate 41 are also fixed, so that the two side formworks 22 are connected with the step formwork 51. Then, the support rod 61 is inserted into the internal card hole 53 through the positioning rod 62, so that it is clamped on the top surface of the step formwork 51.

Then, the head of the hexagonal bolt 65 is clamped in the internal hexagonal hole 66, so that the position of the support rod 61 is fixed. Then, the cross bar 33 is horizontally erected on the bottom surface of the bottom formwork 21 and the top surface of the side formwork 22. The vertical bar 32 intersects with both ends of the cross bar 33, and the cross bar 33 and the vertical bar 32 are fixed together through the fixing member, so as to surround the bottom formwork 21 and the side formwork 22 together, so as to further enhance the stability of the side formwork 22. This device has the advantages of effectively realizing the adjustment of the staircase angle, and being convenient for disassembly and installation.
[0030] Compared with the related art, the adjustable-angle staircase formwork system provided by the present utility model has the following beneficial effects:
[0031] The utility model provides an adjustable-angle staircase formwork system. When the angle of the cast staircase needs to be adjusted, first, by adjusting the height supported by the support frame 1, the overall angle of the formwork structure 2 can be adjusted. When the overall angle of the formwork structure 2 changes, the position of the limit structure 5 will change along with the angle. When pouring concrete, the side wall of the step stage will become an inclined plane, which will affect the aesthetics of the overall staircase. Therefore, it is necessary to loosen the positioning structure 4 and loosen the hexagon bolts 65 that fix the support structure 6, so that the limit structure 5 is no longer restricted by the positioning structure 4 and the support structure 6, enabling the limit structure 5 to rotate between the formwork structures 2, and then rotating the limit structure 5 to the vertical state. Then, the support structure 6 and the positioning structure 4 are fixed again, so that the limit structure 5 is fixed again on the inner side wall of the formwork structure 2. Thus, when pouring concrete later, the side wall of the staircase step stage will be in a horizontal state, making the overall staircase more beautiful. This device effectively realizes the adjustment of the staircase angle and has the advantages of being convenient for disassembly and installation.
