The demoulding method S10 further includes a step S12 of turning over the concrete lattice board 40 so that the bottom surface 42 of the concrete lattice board 40 is placed upward. The demolding method S10 further includes step S13 , providing a demolding device 50 and engaging the demolding device 50 with the mold 20 . The demoulding method S10 further includes a step S14 of activating a driving mechanism 55 to separate the mold 20 from the concrete lattice plate 40 and expose the hole 45 .

Referring to FIG. 10 , according to an embodiment of the present invention, the demolding device 50 includes a support frame 51 , a screw rod 52 and a coupling member 53 . The support frame 51 is configured to stably place the demolding apparatus 50 on the concrete grating 40 .

The substantial center of the support body 512 has a screw hole 513 therethrough. The screw rod 52 is rotatably disposed in the screw hole 513 of the support body 512 .

A coupling member 53 is detachably provided at one end of the screw 52 and is configured to engage with the longitudinal ribs 23 of the die 20 . Specifically, the coupling member 53 includes a disk-shaped structure 530 . The diameter of the disk-shaped structure 530 is selected so that the disk-shaped structure 530 can extend into the interior of the mold 20 and engage the longitudinal ribs 23 . A peripheral edge of the disk-shaped structure 530 has a plurality of grooves 531, and the grooves 531 have a width that allows the longitudinal ribs 23 to pass through. In addition, the coupling member 53 includes a plurality of positioning grooves 54 formed on the disk-shaped structure 530 and alternately arranged with the grooves 53 along the periphery of the disk-shaped structure 530 .

The number of the grooves 531 or the number of the positioning grooves 54 may be greater than the number of the longitudinal ribs 23 of the mold 20 to facilitate the engagement of the mold 20 with the longitudinal ribs 23 .

The above-mentioned step S13 further includes: putting the joint 53 of the demolding device 50 into the mold 20 ( FIG. 11 ), wherein the disk-shaped structure 530 enters the mold 20 at a first predetermined angle. At the above-mentioned first predetermined angle, the groove 531 is relative to the longitudinal rib 23 of the mold 20, so when the disk-shaped structure 530 enters the mold 20, the longitudinal rib 23 passes through the groove 531, so that the disk-shaped structure 530 reaches the longitudinal direction. below the rib 23.

The above step S13 further includes rotating the coupling member 53 to a second predetermined angle ( FIG. 12 ). At the above-mentioned second predetermined angle, the positioning grooves 54 are located below the longitudinal ribs 23 and engage with the longitudinal ribs 23 . In one embodiment, the screw 52 is only engaged with a nut in the center of the coupling member 53 after the coupling member 53 is put into the mold 20 to form a capturing mechanism together. In addition, in the operation of rotating the coupling member 53 from the first predetermined angle to the second predetermined angle, the coupling member 53 is rotated together with the screw rod 52 . Therefore, when the coupling member 53 is rotated, the coupling member 53 will move in the vertical direction at the same time, thereby completing the engagement between the positioning groove 54 and the longitudinal rib 23 .

After the coupling member 53 is engaged with the mold 20, the above-mentioned step S14 is performed: a driving mechanism 55 is activated to separate the mold 20 from the concrete lattice plate 40 and expose the holes 45. In one embodiment, before the driving mechanism 55 is activated, as shown in FIG. 13 , the driving mechanism 55 (for example: a rotary actuator or an electric torque opposite end. In this way, after the driving mechanism 55 is activated, as shown in FIG. 14 , the driving mechanism 55 will rotate the screw rod 52 and make the screw rod 52 move linearly relative to the support frame 51 , thereby separating and exposing the mold 20 from the concrete grid plate 40 Hole 45.

In one embodiment, the method S10 repeats the steps S12-S14 multiple times to separate all the molds 20 from the concrete lattice plate 40 and expose all the holes 45 by using the same demoulding device 50, thereby completing the manufacture of the concrete lattice plate 40, As shown in Figure 15.

FIG. 16 shows a flowchart of a demolding method S20 according to another embodiment of the present invention.

The body 61 is a disk-shaped structure and has an upper surface 611 and a lower surface 612 opposite to the upper surface 611 . The elongate engaging member 62 is fixed to the lower surface 612 of the main body 61 , and the elongate engaging member 62 can extend in a direction perpendicular to the lower surface 612 . The elongate engaging member 62 may extend less than the height of the mold 20 . The impacted structure 63 is disposed above the upper surface 611 of the main body 61 and protrudes from the upper surface 611 of the main body 61 . The impact piece 66 is disposed separately from the main body 61 and used to provide an impact force to the impacted structure 63 . A plurality of handles 64 can be disposed on the main body 61 of the demolding device 60 , and a handle 67 can also be connected to the impact member 66 to facilitate the personnel to operate the demolding device 60 .

In one embodiment, as shown in FIG. 18 , the above-mentioned step S22 further includes a step S23 , placing the body 61 of the demoulding device 60 together with the elongated engaging member 62 on the top surface 41 of the concrete lattice board 40 , wherein the long The shaped engaging piece 62 penetrates through the through hole 215 of the mold 20 and abuts against the upper end of the longitudinal rib 23 located below the through hole 215 . At this time, the height of the limiting structure 65 is slightly higher than the top surface 41 of the lattice board 40 .

After the elongate engaging member 62 is engaged with the mold 20 , the demoulding method S20 further includes step S24 , using the impact member 66 to impact the impacted structure 63 to separate the mold 20 from the concrete lattice plate 40 and expose the hole 45 . Specifically, as shown in FIG. 18 , the impact member 66 is manually or mechanically dropped from above the main body 61 by gravity and impacts the impacted structure 63 . Under the action of the impact external force, as shown in FIG. 19 , the mold 20 will be separated from the concrete lattice plate 40 and the holes 45 will be exposed. It is worth noting that when the body 61 is close to the through hole 45 , the limiting structure 65 will move from the position of the top surface 41 of the lattice plate 40 to abut against the top surface 41 of the concrete lattice plate 40 , thereby preventing the body 61 from entering the through hole 45 . Since the body 61 will rest on the top surface 41 of the concrete grating 40 , the mold 20 will naturally fall with gravity and separate from the elongated engaging member 62 of the demoulding device 60 .
