Description

Technical Field

[0001] This utility model relates to the field of steam curing technology for prefabricated components, specifically a foldable curing cover for assembled prefabricated components. Background Technology

[0002] Steam curing of precast concrete components is a process used to accelerate the strength development of concrete components. It promotes the hydration reaction of concrete through steam heating and humidity control. It is commonly used for precast concrete components in prefabricated buildings, such as walls, beams, and slabs. Existing steam curing technologies for precast concrete components mainly rely on fixed curing kilns and tarpaulin covers, but both have significant technical shortcomings and are difficult to meet the industry's demands for efficient production.

[0003] From the perspective of fixed curing kilns, the core problem lies in the limitations of adaptability caused by their fixed structure. Once the kiln dimensions (such as length, width, and internal height) are completed, they cannot be adjusted. It is difficult to accurately accommodate standardized components ranging from 2 meters to 10 meters in length, as well as irregularly shaped components with eaves / curves. Furthermore, the fixed distribution of heat sources inside the kiln easily leads to localized underheating or overheating (temperature differences can reach ±5℃ or more) when adapting to components of different sizes. This directly results in uneven strength development of the components (the standard deviation of strength within the same batch exceeds 4MPa), and poor stability of the curing effect. At the same time, this fixed structure lacks production flexibility. When the production line switches component types, it is necessary to stop production and adjust the auxiliary facilities inside the kiln, with a single switch taking more than 4 hours. Moreover, its construction period is as long as 1-2 months, and the investment cost of a single kiln exceeds 300,000 yuan. If expansion is needed later, it is necessary to rebuild, resulting in extremely low utilization of fixed assets. Looking at the tarpaulin cover solution, its shortcomings lie in operational efficiency and maintenance reliability. When manually covering, 3-4 people are needed to work together for large components over 3 meters tall, and a single covering takes more than 15 minutes. In addition, the tarpaulin is lightweight and easily affected by wind, resulting in poor alignment accuracy (deviation exceeding 10cm). Sealing is also a core weakness, with gaps easily appearing at the seams of the tarpaulin and where it meets the ground, resulting in a steam loss rate of over 25%. This leads to temperature fluctuations of ±4℃ and unstable humidity inside the cover, and defects such as pitting and bubbles are easily generated on the surface of the components. Furthermore, the tarpaulin material has poor temperature resistance (long-term exposure to steam above 80℃ will accelerate aging) and is easily damaged after friction with the edges of the components. Its average service life is less than 20 maintenance cycles, requiring frequent replacement and resulting in high hidden consumable costs. Therefore, to address the above problems, a prefabricated folding maintenance cover for prefabricated components is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies and solve their multiple deficiencies in adaptability, maintenance stability, operational efficiency, and cost control, and to meet the urgent market demand for steam curing solutions that are "flexibly adaptable to multiple specifications / irregularly shaped components, provide stable curing effects, are easy to operate, and have controllable costs," this utility model proposes a prefabricated component folding curing cover.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the foldable curing cover for prefabricated components of this utility model includes a support frame, two support frames are provided, and a tarpaulin cover is fixedly installed between the two support frames.

[0006] Telescopic bracket assemblies are provided at the front and rear of the two support frames. The telescopic bracket assemblies are fixedly installed with the tarpaulin cover. Tarpaulin 2 is fixedly installed inside the left support frame. Tarpaulin 1 is slidably installed at the front and rear of the right support frame. Magnetic plates are fixedly installed between the two tarpaulins 1 and are magnetically connected. A fixed frame is fixedly connected to the upper left side of the left support frame. An inlet pipe is provided inside the fixed frame through a sealing assembly. The inlet pipe communicates with the inside of the tarpaulin cover. The support frames and telescopic bracket assemblies are galvanized for corrosion protection. The tarpaulin cover and tarpaulins 1 and 2 are all made of heat-resistant and wear-resistant fabric.

[0007] Preferably, the telescopic support assembly includes multiple support rods disposed in front and behind the two support frames. The support rods are fixedly connected to the tarpaulin cover, and omnidirectional brake wheels are fixedly connected to the bottom of the support rods and the bottom of the support frames in front and behind.

[0008] Preferably, the front and rear sides of opposite sides inside the two support frames are rotatably connected to a swing rod 1 via a pivot 1, one end of the swing rod 1 extending to the outside of the support frame. The upper and lower left and right sides inside the support rod are rotatably connected to a swing rod 2 via a pivot 2, one end of the swing rod 2 extending to the outside of the support rod. The swing rod 1 and the swing rod 2 are rotatably connected via a pivot 3, and every two adjacent swing rods 2 are rotatably connected via a pivot 4.

[0009] Preferably, a fixed rod and a connecting rod are fixedly connected between the support frame and the support rod, and between every two support rods. The fixed rod has a T-shaped limiting groove inside, and a limiting block is slidably connected inside the limiting groove. One end of the connecting rod extends into the limiting groove, and the connecting rod is fixedly connected to the limiting block.

[0010] Preferably, the limiting block has a through groove inside, and a locking block is slidably connected to the upper and lower parts of the groove. A spring is fixedly connected between two locking blocks. The upper and lower parts of the left and right sides of the limiting groove have slots. One side of the locking block is engaged in the slot. Both one side of the locking block and the inside of the slot are set in an arc shape.

[0011] Preferably, the sealing assembly includes two sealing clamping plates that are slidably connected to the left and right sides inside the fixed frame. Threaded rods pass through both sides inside the fixed frame and are threadedly connected to the fixed frame. One end of the threaded rod is rotatably installed on one side of the sealing clamping plate, and the other end of the threaded rod is fixedly connected to a handle plate. The other side of the sealing clamping plate is in contact with the outer surface of the inlet pipe. The sealing clamping plate is made of heat-resistant silicone material.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4 As shown, a prefabricated component folding curing cover includes a support frame 1, two of which are provided, and a tarpaulin cover 6 is fixedly installed between the two support frames 1;

[0026] Telescopic bracket assemblies are provided at the front and rear of the two support frames 1. The telescopic bracket assemblies are fixedly installed with the tarpaulin cover 6. Tarpaulin 2 16 is fixedly installed inside the left support frame 1. Tarpaulin 1 8 is slidably installed at the front and rear of the right support frame 1. Magnetic plates 9 are fixedly installed between the two tarpaulins 1 8. The two magnetic plates 9 are magnetically connected. A fixed frame 13 is fixedly connected to the upper left side of the left support frame 1. An inlet pipe 5 is provided inside the fixed frame 13 through a sealing assembly. The inlet pipe 5 communicates with the inside of the tarpaulin cover 6. The support frames 1 and the telescopic bracket assemblies are galvanized for corrosion protection. The tarpaulin cover 6, tarpaulins 1 8, and tarpaulin 2 16 are all made of heat-resistant and wear-resistant fabric. During operation, the curing cover is first placed next to the mold, and then the tarpaulin cover 6 between the two support frames 1 is extended by the telescopic bracket assembly. Since the two tarpaulins 1 8 inside the right support frame 1 are magnetically sealed by the two magnetic plates 9, it is convenient for the two tarpaulins 1 6 inside the right support frame 1 to be opened. The tarpaulin is opened to facilitate the mold's entry into the tarpaulin cover 6. It then connects to an external steam curing machine via an inlet pipe 5, allowing steam to enter the tarpaulin cover 6 for steam curing. The inlet pipe 5 is sealed with a sealing component to prevent steam leakage. Simultaneously, the sealed connection between tarpaulin 8, tarpaulin 16, and tarpaulin cover 6 ensures the overall airtightness of the curing cover. Furthermore, tarpaulin cover 6 can accommodate the opening and closing of the telescopic support assembly. Therefore, this curing cover, through the coordinated design of the telescopic support assembly and tarpaulin cover 6, solves the problem of existing fixed curing kilns being unable to adapt to different specifications and irregularly shaped components due to their fixed structure. It eliminates the need for work stoppages and adjustments due to changes in component dimensions, improving production changeover efficiency. Additionally, the support frame 1 and the telescopic support assembly are galvanized for corrosion protection. Tarpaulin cover 6, tarpaulin 8, and tarpaulin 16 all use heat-resistant and wear-resistant fabrics, overcoming the shortcomings of traditional tarpaulin cover 6, such as short service life and frequent replacement. The entire cover can be reused ≥300 times, significantly reducing consumable costs.

[0027] The telescopic support assembly includes multiple support rods 4 positioned in front and behind two support frames 1. The support rods 4 are fixedly connected to the tarpaulin cover 6. Universal brake wheels 11 are fixedly connected to the bottom of each support rod 4 and the bottom of each support frame 1, both in front and behind. During operation, the tarpaulin cover 6 is supported by the support rods 4 inside the telescopic support assembly. The multiple support rods 4 can be extended and retracted to open and close. Simultaneously, the universal brake wheels 11 at the bottom of the support frame 1 and support rods 4 facilitate the sliding movement of the curing cover, allowing it to move freely along the production line and precisely stop next to any mold. This solves the problem of traditional curing kilns being fixed in a specific position and unable to flexibly adjust with the mold position. It also avoids the problems of laborious manual handling and low alignment accuracy of the tarpaulin cover 6, and reduces movement time.

[0028] Inside the two support frames 1, on opposite sides at the front and rear, a swing rod 2 is rotatably connected via a pivot shaft 1. One end of the swing rod 2 extends to the outside of the support frame 1. Inside the support rod 4, on the upper and lower left and right sides, a swing rod 7 is rotatably connected via a pivot shaft 2. One end of the swing rod 7 extends to the outside of the support rod 4. The swing rod 2 and the swing rod 7 are rotatably connected via a pivot shaft 3, and every two adjacent swing rods 7 are rotatably connected via a pivot shaft 4. During operation, the arrangement of the swing rods 2 and 7 allows the support frame 1 and the support rod 4 to be connected and installed to meet the telescopic requirements, and the connection between the support rods 4 via the swing rods 7 also meets the telescopic requirements.

[0029] A fixed rod 3 and a connecting rod 10 are fixedly connected between the support frame 1 and the support rod 4, and between every two support rods 4. The fixed rod 3 has a T-shaped limiting groove 17 inside, and a limiting block is slidably connected inside the limiting groove 17. One end of the connecting rod 10 extends into the limiting groove 17, and the connecting rod 10 is fixedly connected to the limiting block. During operation, the fixed rod 3 and the connecting rod 10 limit the extension and retraction of the support rods 4 and between the support rods 4, making the extension and retraction process of the telescopic bracket assembly more stable.

[0030] The limiting block has a through groove 20 inside. A locking block 19 is slidably connected to the upper and lower parts of the through groove 20. A spring 21 is fixedly connected between two locking blocks 19. The limiting groove 17 has slots 18 on the upper and lower parts of both the left and right sides inside. One side of the locking block 19 engages with the slot 18. Both one side of the locking block 19 and the inside of the slot 18 are arc-shaped. During operation, the engagement of the locking block 19 with the slot 18 facilitates the stability of the support rod 4 and support frame 1 after extension and retraction. The movement of the support rod 4 and support frame 1 causes the locking block 19 inside the slot 18 to be compressed. After the locking block 19 is compressed, the spring 21 contracts, facilitating the extension and retraction closure of the support rod 4 and support frame 1. Simultaneously, the locking block 19 engages with the slots 18 at different positions to securely limit the extension and retraction of the maintenance cover.

[0031] The sealing assembly includes two sealing clamping plates 12 slidably connected to the left and right sides of the inside of the fixed frame 13. Threaded rods 14 penetrate the left and right sides of the inside of the fixed frame 13, and are threadedly connected to the fixed frame 13. One end of the threaded rod 14 is rotatably mounted to one side of the sealing clamping plate 12, and the other end of the threaded rod 14 is fixedly connected to a handle plate 15. The other side of the sealing clamping plate 12 is in contact with the outer surface of the inlet tube 5. The sealing clamping plate 12 is made of heat-resistant silicone material. During operation, the heat-resistant silicone material is used to seal the inlet tube 5 inserted into the inside of the fixed frame 13. The sealing clamp ensures a good seal between the inlet pipe 5 and the fixed frame 13, preventing leakage when steam enters. At the same time, rotating the handle plate 15 causes the threaded rod 14 to rotate and move. The rotation and movement of the threaded rod 14 causes the sealing clamp plate 12, which is rotatably connected to it, to move inside the fixed frame 13 to seal and clamp the inlet pipe 5. The position of the sealing clamp plate 12 can be adjusted to accommodate inlet pipes 5 of different sizes. This solves the problem of steam leakage (leakage rate exceeding 25%) caused by poor sealing at the pipe penetration point in traditional tarpaulin covers 6, increasing the steam utilization rate to over 90%.

[0032] Example 2

[0033] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, handles 22 are fixedly connected to the front and rear of the opposite sides of the two support frames 1; during operation, the handles 22 facilitate the movement of the support frame 1 and the extension and retraction of the protective cover.
