The slider assembly 3 is slidably installed on the surrounding purlin of the cylinder wall steel form and the surrounding purlin of the bottom beam side form 1 to adjust and limit the relative position of the bottom beam side form 1 and the cylinder wall steel form. The slider assembly 3 of the present invention can slide left and right on the surface of the surrounding purlin, and when it slides to a specific position, it is fixed with the surrounding purlin. After the attached folding plate of the present invention is removed from the mold, it only needs to rotate the bottom beam side form 1 relative to the cylinder wall steel form by a predetermined angle, and it can be lifted to the next level of construction with the drum frame. It not only solves the problem of flipping the bottom beam side form 1, but also is simple to operate. It can also greatly reduce the workload, significantly improve construction efficiency, and ensure construction safety.

[0048] For further information, please refer to Figure 6 and Figure 7 The sliding assembly 3 includes: a first slider 31, a second slider 32, a first connecting rod 33, a second connecting rod 34, two pins 35, a bolt 36 and a nut 37. The first slider 31 is slidably installed on the purlin of the bottom side mold 1 of the beam, and the second slider 32 is slidably installed on the purlin of the cylinder wall steel mold. The first end of the first connecting rod 33 is hinged to the first slider 31 through the pin 35, and the first end of the second connecting rod 34 is hinged to the second slider 32 through the pin 35. The second end of the first connecting rod 33 is connected to the second end of the second connecting rod 34 through the cooperation of the bolt 36 and the nut 37.

[0049] Among them, Figures 8 to 10 As shown, the first slider 31 includes: a body 311, an ear plate 312 arranged at the top of the body 311, a slot 313 opened at the bottom of the body 311 to fit the surrounding purlin of the bottom side mold 1 of the beam, two limiting holes 314 symmetrically opened at the body 311 and connected to the slot 313, and a limiting column matched with the limiting holes 314, and the first end of the first connecting rod 33 is hinged to the ear plate 312 of the first slider 31 through a pin 35. The second slider 32 includes: a body 311, an ear plate 312 arranged at the top of the body 311, a slot 313 opened at the bottom of the body 311 to fit the surrounding purlin of the cylinder wall steel mold, two limiting holes 314 symmetrically opened at the body 311 and connected to the slot 313, and a limiting column matched with the limiting holes 314, and the first end of the second connecting rod 34 is hinged to the ear plate 312 of the second slider 32 through a pin 35. The first slider 31 and the second slider 32 have the same structure, and only the installation and adaptation positions are different. The former is installed on the surrounding purlin of the bottom side mold 1 of the beam, and the latter is installed on the surrounding purlin of the cylinder wall steel mold.

[0050] Accordingly, please refer to Fig.10In order to achieve the limiting fixation between the first slider 31 and the purlin 13 of the bottom side mold 1 of the beam, a limiting hole of the same size is provided on the purlin 13 of the bottom side mold 1 of the beam corresponding to the position of the upper limit hole 314 of the first slider 31; similarly, in order to achieve the limiting fixation between the second slider 32 and the purlin of the cylinder wall steel mold, a limiting hole 314 of the same size is provided on the purlin of the cylinder wall steel mold corresponding to the position of the upper limit hole 314 of the second slider 32. Based on the cooperation between the limiting hole 314 and the limiting column, the position of the first slider 31 and the purlin of the bottom side mold 1 of the beam or the position of the second slider 32 and the purlin of the cylinder wall steel mold is limited and fixed to prevent shaking and ensure construction safety.

[0051] Please refer to Figure 4 and Figure 5 , the height and width of the bottom beam side form 1 are the same as the straight wall surface at the bottom of the beam. The bottom beam side form 1 includes: a panel 11, a frame 12 and a purlin 13. The frame is the edge sealing of the panel. The purlin is located in the frame and close to the panel. The two ends of the purlin are respectively against the opposite sides of the frame. In this embodiment, the purlin 13 is preferably a double-jointed channel steel. The panel 11 of the bottom beam side form 1 is provided with a sub-mouth adapted to the female mouth of the panel 11 of the cylinder wall steel formwork to support seamless docking of the bottom beam side form 1 and the cylinder wall steel formwork when they are molded together, so as to ensure a smooth casting surface and prevent leakage.

[0052] Furthermore, the purlin of the bottom side formwork of the beam and the purlin of the steel formwork of the cylinder wall are both provided with inclined surfaces on the side adjacent to the hinge to form an inverted V shape, providing a rotation space for the bottom side formwork of the beam to rotate relative to the steel formwork of the cylinder wall. Preferably, the angle between the inclined surfaces of the purlin of the bottom side formwork of the beam and the purlin of the steel formwork of the cylinder wall on the side adjacent to the hinge is in the range of 45° to 90°.

[0056] Next, step S2 is performed to positionally fix the slider assembly 3 and the surrounding purlin of the cylinder wall steel mold before closing the mold. The positional fixation is mainly achieved by inserting the position-limiting column into the position-limiting hole 314 of the second slider 32 and the position-limiting hole on the surrounding purlin of the cylinder wall steel mold.

[0057] Next, please refer to Fig.11 , execute step S3, when closing the mold, rotate the beam bottom side mold 1 so that the sub-mouth of its panel 11 is matched with the female mouth of the cylinder wall steel mold panel 11, and at the same time, the slider assembly 3 and the surrounding purlin 13 of the beam bottom side mold 1 are limited and fixed;
