[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 3 The utility model provides a technical solution: a diagonal cantilever formwork frame structure, including a formwork frame structure body, the formwork frame structure body includes a fixed seat 1 and a wall 17, the fixed seat 1 is welded with a fixed ear 3, a rotating shaft 4 is rotatably installed between the fixed ear 3, a support rod 5 and a fixed rod 6 are respectively installed on the rotating shaft 4, the fixed rod 6 and the support rod 5 are both provided with a cavity 19, a connecting rod 18 is movably installed inside the cavity 19, a limit block 20 is welded at one end of the connecting rod 18, a protrusion is fixed on the inner wall of the cavity 19, and the protrusion cooperates with the limit block 20, a fixed block 7 is welded on the side of the fixed rod 6, a rotating column 8 is fixedly installed on the fixed block 7, and a movable column 9 is installed on the rotating column 8, the rotating column 8 provides a support point for the rotation of the movable column 9, and the movable column 9 and the limit column 11 are adjusted and installed according to the installation position in the later stage.

[0022] In this embodiment, a support plate 13 is welded to the side of the support rod 5, and a fixing groove 14 is opened on the support plate 13. A limiting plate 12 is movably installed inside the fixing groove 14, and a limiting column 11 is welded on the limiting plate 12. A support column 10 is movably installed on one end of the limiting column 11, and the other end of the support column 10 is connected to the movable column 9. Threaded holes are opened inside the movable column 9 and the limiting column 11, and a threaded column 16 is rotatably installed inside the threaded hole. One end of the threaded column 16 is respectively fixed on the support column 10. As the support column 10 rotates, the threaded column 16 causes the limiting column 11 and the movable column 9 to move outward or inward at the same time, thereby adjusting the length between the movable column 9 and the limiting column 11.

[0023] In this embodiment, a fixing hole 2 is formed on the fixing seat 1, and a fixing frame 15 is movably installed inside the fixing hole 2. The fixing seat 1 is fixedly installed on the wall 17 by bolts, and an I-beam 21 is fixedly installed on the wall 17. The fixing seat 1 is fixedly installed on the I-beam 21. The width of the fixing groove 14 is greater than the thickness of the limiting plate 12. The limiting plate 12 is formed with a mounting hole. The fixing frame 15 is installed inside the fixing hole 2. When fixing the circular steel pipe, the fixing frame 15 can be used to complete the clamping and fixing, which meets the installation and use of the fixing seat 1 in different situations.

[0024] When the device is in use, the support column 10 is first rotated, and the rotation of the support column 10 moves one end of the limit column 11 downward, so that the limit plate 12 moves to the center position of the fixed groove 14, and the limit column 11 drives the limit plate 12 to be taken out from the inside of the fixed groove 14. After being taken out, the limit column 11 and the movable column 9 are tilted by the rotating column 8. During installation, the fixing seat 1 is respectively installed on the wall 17 and the I-beam 21 by bolts and the fixing frame 15. The support rod 5 and the fixing rod 6 make the connecting rod 18 move inside the support rod 5 and the fixing rod 6 according to different inclination angles to expose, and after being exposed, the support rod 5 and the fixing rod 6 are increased as a whole Length, after the support rod 5 and the fixed rod 6 are fixed, the support rod 5 and the fixed rod 6 are tilted and distributed on the fixed hanging ear 3 through the rotating shaft 4, and the limit plate 12 is fixed to the wall 17. One end of the fixed rod 6 generates a pulling force through the movable column 9, and the pulling force causes the fixed rod 6 and the connecting rod 18 to be limited and fixed. Through the rotation of the support column 10, the threaded column 16 drives the movable column 9 and the limiting column 11 to move inward at the same time. When the limiting column 11 moves, a pulling force is generated for the fixed rod 6, and the pulling force provides a supporting force for the fixed rod 6. The three-point support of the fixed seat 1 and the limiting plate 12 provides support and limit fixation for the I-beam 21 and the formwork frame.
