A limiting rod 22 is provided through two adjacent through holes. The top and bottom ends of the limiting rod 22 extend into the adjacent cavity. The top and bottom ends of the limiting rod 22 are fixedly connected to a fixing plate 21. The fixing plate 21 is located in the adjacent cavity. In step four, the base mechanism includes several wooden templates 3. The several wooden templates 3 are arranged linearly from left to right. The bottom of the wooden templates 3 is fixedly connected to the four corners with fixing blocks 23.

[0019] Limiting plates 13 are fixedly connected to both sides of the swing plate 8. Each limiting plate 13 has a groove on its top. A fixing block 23 is located within an adjacent connecting groove. Lead screws 6 are inserted into both the front and rear sides of the support plate 5. The end of the lead screw 6 furthest from the support plate 5 is threaded through an adjacent square threaded tube 15. Connecting posts 7 are fixedly connected to the top and bottom of the lead screw 6 near the support plate 5. Limiting grooves are formed on the U-shaped plate 4, and L-shaped plates 9 pass through each limiting groove. Connecting posts 7 are fixedly connected to the L-shaped plates 9 near the support plate 5. A baffle 19 is attached. The side of the L-shaped plate 9 away from the U-shaped plate 4 is attached to the side of the adjacent square threaded tube 15 away from the support plate 5. An annular groove is opened at the end of the square threaded tube 15 away from the support plate 5. A first magnetic ring 18 is fixedly connected in the annular groove. A movable hole is opened on the side of the L-shaped plate 9 away from the U-shaped plate 4.

The side of the second magnetic ring 20 away from the first magnetic ring 18 is fixedly connected to the side of the adjacent L-shaped plate 9.

[0020] Working principle: The triangular support mechanism is placed on the connecting support mechanism, which supports the triangular support mechanism through the U-shaped plate 4. The U-shaped plate 4, together with the support column 2 and the steel pipe support frame 1, provides support. The second magnetic ring 20 on one side of the L-shaped plate 9 on the U-shaped plate 4 is placed in the annular groove at one end of the square threaded pipe 15. The second magnetic ring 20 is magnetically connected to the first magnetic ring 18 in the annular groove. The L-shaped plate 9, together with the U-shaped plate 4, can further expand the support range for the triangular support mechanism. When it is necessary to adjust the angle and horizontal length of the triangular support mechanism, the connecting column 7 is rotated. 7 drives the lead screw 6 to rotate, which in turn drives the square threaded tube 15 to move. The square threaded tube 15 drives the swing plate 8 to swing through the second U-shaped block 16. The swing plate 8, in conjunction with the second connecting shaft and the fourth damping bearing 17, swings inside the second U-shaped block 16. The two swing plates 8 swing between each other through the fourth connecting shaft and the second damping bearing 12. During the swinging process of the swing plate 8, it will drive the adjacent first movable plate 24 to swing. The first movable plate 24 swings through the through groove on the swing plate 8 via the third connecting shaft and the first damping bearing 11. The first movable plate 24 is connected to the fixed plate 2. 1. The limiting rod 22 drives the second movable plate 25 to swing. The second movable plate 25 swings inside the first U-shaped block 10 via the first connecting shaft and the third damping bearing 14. During the swinging process of the swing plate 8, the relationship between the first movable plate 24 and the second movable plate 25 will change. The limiting rod 22, in conjunction with the fixed plate 21, can connect and limit the first movable plate 24 and the second movable plate 25, thereby adjusting the angle and length of the triangular support mechanism. When the square threaded tube 15 moves out of the support range of the U-shaped plate 4, the L-shaped plate 9 can replace the U-shaped plate 4 to support the square threaded tube 15. The L-shaped plate 9 stops moving only after the baffle 19 contacts the U-shaped plate 4, and the square threaded pipe 15 stops moving accordingly. Then, the wooden formwork 3 is placed on top of the adjacent triangular support mechanism using external equipment. The fixing block 23 at the bottom of the wooden formwork 3 is aligned with the connecting groove at the top of the limiting plate 13 to install the wooden formwork 3. After the steel bars are tied and the inspection is passed, the sloping roof concrete is poured. The roof concrete is covered with a film or watered for curing. After the roof concrete reaches the required strength, the triangular support mechanism and the connecting support mechanism are removed, and the ridge slope concrete pouring construction is completed.
