[0018] As a further aspect of the invention, the upper surface of the support mold is provided with several limiting grooves, and several support rods are embedded in the limiting grooves of the support mold. The top of the support rods is flush with the upper surface of the support mold, and the lower part of the support rods is provided with a through groove.

[0019] The beneficial effects of this invention are:

[0020] (1) After laying the steam pipes on the support mold, transport the PC component to the support mold. Then, place several outer cover frames side by side at equal intervals around the PC component. At the same time, adjust the height of each outer cover frame according to the height of the PC component. The height of the outer cover frame is adjusted by setting the height of the adjusting vertical rod extending out of the support square tube. Then, connect two adjacent support top frames through the installation slots and sealing grooves of each top film. Connect two adjacent support square tubes through the installation slots and sealing grooves of each side film. Keep the top film and side film sealed. Then, install the film roll box on the two outer cover frames at the beginning and end. Take out the door curtain film rolled up in the film roll box. Align the first front support plate and the second front support plate with the two sides of the door curtain film to keep the two ends sealed by the door curtain film. The system is sealed, and then steam is supplied through steam pipes to the enclosed space covered by the top film, side film and door curtain film to steam cure the PC components placed on the support mold. When heat preservation is required, the support top plate, the first side support plate and the second side support plate make it easy to install insulation boards on the outer periphery of the outer cover frame. The external insulation boards maintain the temperature, reduce steam loss and improve energy utilization. At the same time, the support top plate, the first side support plate and the second side support plate allow for the installation of various insulation boards on the outer periphery of the outer cover frame, so that users can reasonably arrange different types of insulation boards according to actual production activities. The overall assembly and disassembly are very simple, convenient and quick, and the size and quantity can be flexibly adjusted according to the size of the PC components, so as to flexibly adapt to different production requirements, broaden the working scope and improve work efficiency.

[0021] (2) When adjusting the height of the support frame, raise and lower the adjusting vertical rod, then tighten the first nut and the second nut in sequence, pushing the first pad and the second pad to push the support square tube, thereby fixing the position of the adjusting vertical rod. At the same time, the limiting square tube fills the gap between the adjusting vertical rod and the support square tube, further maintaining the stable support of the adjusting vertical rod, thus maintaining the overall structural stability. Through the corresponding engagement of the mounting block and the mounting slot, and the corresponding sealing engagement of the sealing strip and the sealing groove, the top film and the side film connect the two adjacent outer canopy frames and keep the connection sealed, thereby reducing the leakage of steam and heat, reducing energy loss, and improving energy utilization efficiency. Through the corresponding sealing connection of the first sealing strip and the first connecting strip, the connecting film is installed between the top film and the side film, thereby adapting to different outer canopy frames. The height of the frame is adjusted to maintain the airtightness of each film covering the outer perimeter, reducing steam and heat loss and improving energy efficiency. Adjacent connecting films are sealed to each other via a second sealing strip and a second connecting strip. A waist-shaped groove accommodates insulation boards of different specifications, which are then fixed with bolts and nuts, increasing adaptability. When the PC component is placed on the support mold, the steam pipe passes through the through groove and is laid in the limiting groove of the support mold and on both sides of the support mold. Support rods support the PC component, assisting the support mold and reducing the pressure on it. This facilitates the laying of the steam pipe and allows it to be located below the PC component, maintaining close proximity to it, improving steam adhesion and curing efficiency, increasing overall yield, and ensuring optimal curing results.

The tops of two adjacent outer cover frames 1 are connected by a top film 2, and the sides of two adjacent outer cover frames 1 are connected by a side film 3. A film roll box 4 is installed on the top of the two outer cover frames 1 at the beginning and end. A curtain film 5 is rolled up and installed in the film roll box 4 to seal the two outer cover frames 1 at the beginning and end. A support mold platform 6 for supporting each PC component is provided on the bottom side of the inner side of the outer cover frames 1. The outer cover frame 1 includes a support square tube 8 and a support top frame 9. Adjustable vertical rods 13 are fixedly connected to the lower parts of both ends of the support top frame 9. Two support square tubes 8 are provided and are movably sleeved on the outer periphery of the adjusting vertical rods 13. A support base 7 is fixedly connected to the lower end of each support square tube 8. Several openings are provided on both sides of the inner sidewall of the two support square tubes 8. The mounting slots 27 are evenly distributed at equal intervals. Two symmetrically arranged sealing grooves 28 are opened in the middle of the inner side wall of each of the two supporting square tubes 8. The mounting slots 27 and the sealing grooves 28 are opened on the inner side wall of the supporting top frame 9. Two symmetrically arranged first side support plates 12 are fixedly connected to the outer side wall of each of the two supporting square tubes 8. Two symmetrically arranged second side support plates 15 are fixedly connected to the two sides of each end of the supporting top frame 9. The front side of the two first supporting square tubes 8 and the rear side of the two last supporting square tubes 8 are fixedly connected to the first front support plate 11. The front sides of the first supporting top frame 9 and the rear sides of the last supporting top frame 9 are fixedly connected to the second front support plate 14. The top of the supporting top frame 9 is provided with a supporting top plate 10 for supporting the film roll box 4. Universal wheels with foot brakes are installed on the lower sides of both ends of the supporting base 7.

[0033] In this embodiment, after the steam pipes are laid on the support mold 6, the PC component is transported and placed on the support mold 6. Then, several outer cover frames 1 are arranged side by side at equal intervals around the PC component. At the same time, the height of each outer cover frame 1 is adjusted according to the height of the PC component. During adjustment, the height of the outer cover frame 1 is adjusted by setting the adjusting vertical rod 13 to extend beyond the support square tube 8. Then, each top film 2 is connected to two adjacent support top frames 9 through the mounting slot 27 and sealing groove 28. Each side film 3 is connected to two adjacent support square tubes 8 through the mounting slot 27 and sealing groove 28, and the top film 2 and side film 3 are kept sealed. Then, the roll film box 4 is installed on the two outer cover frames 1 located at the beginning and end. The door curtain film 5 rolled up in the roll film box 4 is taken out and connected to the two sides of the door curtain film 5 through the first front support plate 11 and the second front support plate 14, so that the door curtain film can be opened. The membrane 5 maintains the seal at both ends, and then steam is supplied through steam pipes to the enclosed space covered by the top membrane 2, side membranes 3, and curtain membrane 5 to steam-cur the PC components placed on the support mold table 6. When heat preservation is required, the support top plate 10, the first side support plate 12, and the second side support plate 15 facilitate the installation of insulation boards on the outer periphery of the outer cover frame 1. The external insulation boards maintain the temperature, reduce steam loss, and improve energy utilization. At the same time, the support top plate 10, the first side support plate 12, and the second side support plate 15 allow for the installation of various insulation boards on the outer periphery of the outer cover frame 1, making it convenient for users to reasonably arrange different types of insulation boards according to actual production activities. The overall assembly and disassembly are very simple, convenient, and quick, and the size and quantity can be flexibly adjusted according to the size of the PC components, thereby flexibly adapting to different production requirements, expanding the working range, and improving work efficiency.

[0034] A limiting tube 16 is fitted between the lower outer periphery of the adjusting vertical rod 13 and the inner wall of the supporting square tube 8. A first limiting post 17 is movably inserted through the middle of the limiting tube 16. The first limiting post 17 movably passes through the lower end of the adjusting vertical rod 13 and the supporting square tube 8. A first sliding groove 21 is opened in the middle of both sides of the supporting square tube 8 to cooperate with the sliding of the first limiting post 17. A limiting thread 19 is opened at both ends of the first limiting post 17, and a first nut 18 is threaded onto the first limiting post 17 through the limiting thread 19. A first pad 20 is fitted on both ends of the first limiting post 17 and between the first nut 18 and the supporting square tube 8.

[0035] The second limiting post 22 is threaded through the middle of the first limiting post 17. The second limiting post 22 movably passes through the supporting square tube 8. The side wall of the supporting square tube 8 is provided with a second sliding groove 26 that cooperates with the second limiting post 22 to slide up and down. The second limiting post 22 is threaded through the limiting square tube 16 and the adjusting vertical rod 13. The side of the second limiting post 22 located outside the supporting square tube 8 is threaded with a second nut 23. A second pad 25 is provided between the second nut 23 and the supporting square tube 8. The second limiting post 22 movably passes through the second pad 25. The end of the second limiting post 22 located outside the supporting square tube 8 is fixedly connected with a hexagonal rod head 24 for easy installation.

[0036] In this embodiment, when adjusting the height of the support top frame 9, the adjusting vertical rod 13 is raised and lowered, and then the first nut 18 and the second nut 23 are tightened in sequence. The first pad 20 and the second pad 25 are pushed to push the support square tube 8, thereby fixing the position of the adjusting vertical rod 13. At the same time, the gap between the adjusting vertical rod 13 and the support square tube 8 is filled by the limiting square tube 16, further maintaining the stable support of the adjusting vertical rod 13, thereby maintaining the overall structural stability.

[0037] Both sides of the top membrane 2 and the side membrane 3 are fixedly connected with mounting blocks 35 and sealing strips 36 from the inside out. The mounting blocks 35 are engaged with the mounting slots 27, and the sealing strips 36 are engaged with the sealing grooves 28. During operation, the corresponding engagement of the mounting blocks 35 with the mounting slots 27 and the corresponding sealing engagement of the sealing strips 36 with the sealing grooves 28 connects the top membrane 2 and the side membrane 3 to the two adjacent outer canopy frames 1 and keeps the connection sealed, thereby reducing the leakage of steam and heat, reducing energy loss, and improving energy utilization efficiency.

[0038] Connecting films 34 are provided at both ends of the top film 2 and between the two side films 3. A first sealing strip 39 is fixedly connected to the side of the connecting film 34 near the top film 2 and the side of the side film 3 near the connecting film 34. A first connecting strip 40 is fixedly connected to the side of the connecting film 34 near the side film 3 and the side of the top film 2 near the connecting film 34. The first sealing strip 39 and the first connecting strip 40 are correspondingly sealed and connected. A second sealing strip 41 and a second connecting strip 42 are fixedly connected to the other two sides of the connecting film 34, and adjacent second sealing strips 41 and second connecting strips 42 are correspondingly sealed and connected. During operation, the connecting film 34 is installed between the top film 2 and the side film 3 through the corresponding sealing connection of the first sealing strip 39 and the first connecting strip 40, thereby adapting to different heights of the outer cover frame 1 and maintaining the sealing performance of each film when it is placed on the outer perimeter, reducing the loss of steam and heat, and improving energy utilization. At the same time, adjacent connecting films 34 are correspondingly sealed and connected through the second sealing strip 41 and the second connecting strip 42, thereby further ensuring the sealing performance and reducing losses.

[0039] A row of equidistant connecting buckles 29 and a sealing strip 30 are fixedly connected to the first sealing strip 39, the second sealing strip 41, the first front support plate 11, and the second front support plate 14. A row of equidistant connecting blocks 37 and a sealing sleeve 38 are fixedly connected to the first connecting strip 40, the second connecting strip 42, and both sides of the curtain film 5. The connecting buckles 29 and the connecting blocks 37 are engaged, and the sealing strips 30 and the sealing sleeves 38 are engaged to seal, thereby ensuring the sealing of the seams of each film and reducing losses.

[0040] The upper surface of the support mold 6 is provided with several limiting grooves, and several support rods 43 are embedded in the limiting grooves of the support mold 6. The top of the support rods 43 is flush with the upper surface of the support mold 6, and the lower part of the support rods 43 is provided with a through groove 44. When the PC component is placed on the support mold 6, the steam pipe passes through the through groove 44 and is laid in the limiting groove of the support mold 6 and on both sides of the support mold 6. The support rods 43 support the PC component, assist the support mold 6 and reduce the pressure on the support mold 6. At the same time, it facilitates the laying of the steam pipe and allows the steam pipe to be located on the lower side of the PC component, keeping it in close contact with the PC component, improving the adhesion and curing efficiency of steam, improving the overall yield, and ensuring that the curing effect reaches the best.

[0041] The first front support plate 11 has a first groove 31 in the middle to accommodate the sliding of the first pad 20, and the first side support plate 12 has a second groove 32 in the middle to accommodate the sliding of the second pad 25. The sides of the first side support plate 12 and the second side support plate 15 each have several waist-shaped grooves 33 that are evenly distributed at equal intervals. The waist-shaped grooves 33 accommodate insulation boards of different specifications and fix them with bolts and nuts, thereby improving the adaptability and work efficiency.

[0042] In use, after laying the steam pipes on the support mold 6, the PC component is transported and placed on the support mold 6. Then, several outer cover frames 1 are arranged side-by-side at equal intervals around the PC component. The height of each outer cover frame 1 is adjusted according to the height of the PC component. Adjustment is achieved by extending the vertical rod 13 beyond the support tube 8. Adjacent support top frames 9 are then connected via mounting slots 27 and sealing grooves 28 using the top films 2. Adjacent support tubes 8 are connected via mounting slots 27 and sealing grooves 28 using the side films 3, maintaining a seal through the top and side films 2. The film roll cassette 4 is then installed onto the two outer cover frames 1 at the beginning and end. The curtain film 5 rolled up in the film roll cassette 4 is then removed and connected to the two sides of the curtain film 5 via the first front support plate 11 and the second front support plate 14, thereby allowing the curtain film to pass through. The curtain film 5 maintains the seal at both ends, and then steam is supplied through the steam pipe to the enclosed space covered by the top film 2, the side film 3 and the curtain film 5 to steam-cur the PC components placed on the support mold table 6. When heat preservation is required, the support top plate 10, the first side support plate 12 and the second side support plate 15 make it easy to install insulation boards on the outer periphery of the outer cover frame 1. The external insulation boards maintain the temperature, reduce steam loss and improve energy utilization. At the same time, the support top plate 10, the first side support plate 12 and the second side support plate 15 allow for the installation of various insulation boards on the outer periphery of the outer cover frame 1, so that users can reasonably arrange different types of insulation boards according to actual production activities. The overall assembly and disassembly are very simple, convenient and quick, and the size and quantity can be flexibly adjusted according to the size of the PC components, so as to flexibly adapt to different production requirements, broaden the working range and improve work efficiency.

[0043] When adjusting the height of the supporting top frame 9, the adjusting vertical rod 13 is raised and lowered, and then the first nut 18 and the second nut 23 are tightened in sequence. This pushes the first pad 20 and the second pad 25 to push the supporting square tube 8, thereby fixing the position of the adjusting vertical rod 13. At the same time, the limiting square tube 16 fills the gap between the adjusting vertical rod 13 and the supporting square tube 8, further maintaining the stable support of the adjusting vertical rod 13, thus maintaining the overall structural stability. Through the corresponding engagement of the mounting block 35 with the mounting slot 27 and the corresponding sealing engagement of the sealing strip 36 with the sealing groove 28, the top film 2 and the side film 3 connect the two adjacent outer cover frames 1 and keep the connection sealed, thereby reducing the leakage of steam and heat, reducing energy loss, and improving energy utilization efficiency. Through the corresponding sealing connection of the first sealing strip 39 and the first connecting strip 40, the connecting film 34 is installed between the top film 2 and the side film 3. This allows for adaptation to different heights of the outer cover frame 1, maintaining the airtightness of each film cover on the outer perimeter, reducing steam and heat loss, and improving energy utilization. Simultaneously, adjacent connecting films 34 are sealed to each other via the second sealing strip 41 and the second connecting strip 42. The waist-shaped groove 33 accommodates insulation boards of different specifications, which are then fixed with bolts and nuts, increasing the adaptability. When the PC component is placed on the support mold 6, the steam pipe passes through the through groove 44 and is laid in the limiting groove of the support mold 6 and on both sides of the support mold 6. The support rod 43 supports the PC component, assisting the support mold 6 and reducing the pressure on it. This also facilitates the laying of the steam pipe and allows it to be located below the PC component, maintaining close proximity to it, improving steam adhesion and curing efficiency, increasing the overall yield, and ensuring optimal curing results.
