After the formwork assembly and the template assembly are hoisted to the silo roof, the steel corbel 11 is installed, the slot 623 at the lower end of the connector 6 is plugged into the upper surface of the steel corbel 11, and the connector 6 and the steel corbel 11 are fastened together with bolts. At this time, the hydraulic cylinder 622 is in an extended state, and the formwork assembly and the template assembly fall down, so that the upper surface of the upper connecting block 61 abuts against the lower surface of the mounting frame 2, the first connecting hole 26 is aligned with the second connecting hole 611 and fastened with bolts, and the motor 335 is reversed to reset the avoidance puzzle plate 34 that rotates later first, and then reset the avoidance puzzle plate 34 that rotates earlier. At this time, the installation of the entire formwork assembly and the template assembly is completed, and the silo roof can be poured after other protective work is done; When the casting of the silo roof is completed and the formwork needs to be evacuated, the hydraulic cylinder 622 is started to retract the piston rod of the hydraulic cylinder 622, and the upper connecting block 61 descends, driving the entire formwork assembly and the template assembly to descend, so that the template assembly is separated from the cast silo roof cone shell. When the piston rod of the hydraulic cylinder 622 has completely retracted, the hydraulic cylinder 622 is closed, and the avoidance puzzle 34 is flipped to the same position as when the formwork assembly was installed, and then the hook of the crane is connected to the lifting ring 44, and the steel corbel 11 and the connecting piece 6 are removed, so that the entire formwork assembly and the template assembly fall, and the embedded screw 12 passes through the corresponding gap until the lower end of the formwork assembly contacts the ground, and the overall disassembly of the formwork assembly and the template assembly is completed. When the device is in use, the entire structure is assembled by assembling multiple groups of parts, the template 3 is set between two adjacent diagonal braces 51, the formwork assembly and the template assembly are hoisted as a whole, and the detachable connection makes the installation and disassembly of the entire structure more convenient. During installation and disassembly, it is only necessary to rotate the avoidance puzzle to allow the entire formwork assembly to pass through the embedded screw 12 to achieve the purpose of overall hoisting and avoid friction between the edge of the template 3 and the wall of the silo 1. Compared with traditional construction methods, it is faster, has a shorter construction period, and reduces safety risks.
