Description

Technical Field

[0001] This invention relates to the field of precast steel formwork technology, specifically to a quick-release steel formwork for efficient forming of precast components. Background Technology

[0002] Precast steel formwork is a mold used to manufacture precast concrete components. It is usually made of high-strength steel, which has good strength, rigidity and durability. The main function of steel formwork is to provide a forming space for precast concrete components, ensuring that the precast components maintain the required shape and size during the pouring process. It is used to produce various precast concrete components, such as precast beams, precast slabs, precast columns, etc.

[0003] Steel formwork typically consists of a casting slab, a base, and a scraper. When in use, the casting slab is used to directly contact the concrete and form the outline of the component. The base serves as the supporting foundation for the steel formwork, bearing the overall load of the formwork and ensuring its stability during the casting process. The scraper is used to smooth the surface after the concrete is poured, removing excess concrete and ensuring a smooth and flat surface for the component.

[0004] However, in the existing technology, traditional steel formwork is usually assembled and disassembled by bolt connection. Although it can meet the basic structural requirements, it has significant problems in terms of construction efficiency and ease of operation. Bolt connection requires manual tightening and loosening one by one. This process is not only time-consuming and laborious, but also prone to loose connection or difficulty in disassembly due to improper operation. Therefore, this invention proposes a quick-disassembly steel formwork for efficient forming of precast components. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a quick-release steel template for efficient prefabrication, solving the problem of the inability to quickly disassemble.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a quick-release steel template for efficient forming of precast components, comprising a base, a disassembly mechanism provided on the top of the base, two connecting rods fixedly connected to the outside of the disassembly mechanism, a scraping mechanism provided inside the two connecting rods, a support plate fixedly connected to the bottom of the base, and an ejection mechanism provided on the top of the support plate.

[0007] The disassembly mechanism includes two second connecting plates, the bottom of which is located on the top of the base. A first connecting plate is slidably connected to both outer sides of the two second connecting plates. A heating component is provided on the outside of the first connecting plates. Multiple heat-conducting columns are fixedly connected to both outer sides of the second connecting plates. A cone block is fixedly connected to the outside of each heat-conducting column. An expansion block is slidably connected to the outside of each heat-conducting column. An alignment column is fixedly connected to the inside of each cone block. Engaging components are provided on the outside of the first connecting plates and the outside of the second connecting plates.

[0008] Preferably, the heating assembly includes two heaters, the bottoms of which are fixedly connected to the top sides of the base. Two conveying pipes are fixedly connected to the outside of each of the two heaters. Two connecting pipes are fixedly connected to the outside of the first connecting plate, i.e., the side closest to the heater. The outside of the conveying pipes is fixedly connected to the inside of the connecting pipes. The outside of the heat-conducting column penetrates through the inside of the connecting pipes.

[0009] Preferably, the engaging assembly includes multiple support blocks, the multiple support blocks are fixedly connected to the outside of the second connecting plate, the first connecting plate is fixedly connected to a connecting block, the support blocks are rotatably connected to a rotating buckle, the connecting blocks are fixedly connected to a locking plate, a limit block is fixedly connected to one side of the locking plate, and the rotating buckle is rotatably connected to the outside of the locking plate.

[0010] Preferably, the scraping mechanism includes two slide rods, the two slide rods being slidably connected to the outside of the two connecting rods, and a limit plate being fixedly connected to the outside of the two slide rods.

[0011] Preferably, a crossbar is fixedly connected to the outside of the two slide bars, i.e., the side away from the connecting rod, and a scraper is fixedly connected to the bottom of the crossbar.

[0012] Preferably, a sliding block is slidably connected to the outside of the crossbar, and the sliding block is slidably connected to the outside of the scraper bar.

[0013] Preferably, the ejection mechanism includes a hydraulic cylinder, which is externally fixedly connected to the top of the support plate, and the output end of the hydraulic cylinder is fixedly connected to a connecting plate.

[0014] Preferably, the first connecting plate is externally fixedly connected to a support rod, and the second connecting plate is externally fixedly connected to a locking block.

[0015] Preferably, the outer side of the connecting plate is located on top of the support rod and the locking block, and the outer side of the connecting plate is attached to the outer side of the first connecting plate and the second connecting plate.

[0016] Preferably, the expansion block is composed of two cones and a column, with the column connected to one side of the larger circumferential surface of the two cones.

[0017] This invention provides a quick-release steel template for efficient precast component forming. It possesses the following features:

[0018] Beneficial effects:

[0019] 1. This invention heats the heat-conducting column using a heating component, transferring the heat to the expansion block, causing it to expand and push the cone block, thus ensuring a tight fit between the first and second connecting plates. This ensures the stability of the formwork during the pouring process. After the concrete is formed, heating is stopped, the expansion block cools and shrinks, and the connection is released. The first and second connecting plates are then quickly disassembled using a locking component, enabling rapid disassembly of the formwork. This improves the production efficiency of precast components and reduces manual operation time.

[0020] 2. The present invention can effectively remove excess concrete from the surface of precast components by sliding the sliding rod in the groove inside the connecting rod, ensuring the surface of the precast components is flat. At the same time, the sliding block cleans the scraper in real time to prevent the accumulation of residues, further improving the cleaning effect and improving the quality of surface treatment of precast components.

[0021] 3. This invention ensures that the precast component can be smoothly ejected from the template by the extension and retraction of the hydraulic cylinder and the smooth movement of the connecting plate, avoiding damage or deformation of the precast component during demolding, thus improving the integrity and quality of the precast component. At the same time, the support rod and the locking block provide stable support for the connecting plate, ensuring that the connecting plate remains stable during ejection, further enhancing the reliability of the demolding process.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 This invention provides a quick-release steel template for efficient prefabrication, including a base 1 designed to provide support. A disassembly mechanism 2 is provided on the top of the base 1. Two connecting rods 3 are fixedly connected to the outside of the disassembly mechanism 2, which is designed to provide support and connection. The inside of the disassembly mechanism 2 has a groove to provide sliding space. A scraping mechanism 4 is provided inside the two connecting rods 3. A support plate 5 is fixedly connected to the bottom of the base 1, which is designed to provide support. The outside of the support plate 5 is vertically located at the bottom of the base 1. An ejection mechanism 6 is provided on the top of the support plate 5.

[0033] The disassembly mechanism 2 includes two second connecting plates 22, designed to provide connectivity. The bottoms of the two second connecting plates 22 are located on the top of the base 1. First connecting plates 21 are slidably connected to both outer sides of the two second connecting plates 22. By bringing one side of the second connecting plates 22 and the first connecting plates 21 closer together, a rectangular space can be formed, allowing for pouring into it. A heating component 23 is provided on the outside of the first connecting plates 21. Multiple heat-conducting columns 24 are fixedly connected to both outer sides of the second connecting plates 22, designed to provide guiding and alignment capabilities, ensuring alignment during assembly with the first connecting plates 21. The external fixed connection of the heat-conducting column 24 is a cone block 25, which is designed to provide alignment capability so that it can fit the connection of the first connecting plate 21. The external sliding connection of the heat-conducting column 24 is an expansion block 26, which is composed of two cones and a column. The column is connected to one side of the larger circumferential surface of the two cones, so that the expansion block 26 can be thermally expanded when heated and can be cold-contracted when exposed to low temperature. The internal fixed connection of the cone block 25 is an alignment column 27, which is designed to provide docking capability so that the expansion block 26 can dock well with the cone block 25. The external of the first connecting plate 21 and the external of the second connecting plate 22 are provided with a locking assembly 28.

[0034] like Figure 1 , Figure 5 and Figure 7 The heating assembly 23 includes two heaters 233, designed to generate heat upon energization (this is prior art and will not be described in detail here). The bottoms of the two heaters 233 are fixedly connected to the top sides of the base 1. Two conveying pipes 232 are fixedly connected to the outside of each heater 233, providing conveying capacity to transport the heat generated by the heaters 233. Two connecting pipes 231 are fixedly connected to the outside of the first connecting plate 21, i.e., the side closest to the heaters 233, providing docking capability to receive heat from the conveying pipes 232. Heat comes into contact with the heat-conducting column 24 inside the connecting pipe 231, allowing heat to be transferred to the expansion block 26. When the expansion block 26 is heated, it expands, which locks the connection between the first connecting plate 21 and the second connecting plate 22, preventing it from falling off during use. After the concrete is formed, the expansion block 26 cools down, allowing the connection between the first connecting plate 21 and the second connecting plate 22 to be quickly disassembled, enabling rapid storage and disassembly. The outside of the conveying pipe 232 is fixedly connected to the inside of the connecting pipe 231, and the outside of the heat-conducting column 24 penetrates the inside of the connecting pipe 231.

[0035] like Figure 2 and Figure 3The engaging assembly 28 includes multiple support blocks 281, designed to provide support and be fixed to the outside of the two second connecting plates 22. The support blocks 281 are fixedly connected to the outside of the second connecting plates 22. A connecting block 283 is fixedly connected to the outside of the first connecting plate 21, designed to provide rotational capability and provide good support to the outside of the first connecting plate 21. A rotating buckle 282 is rotatably connected to the outside of the support block 281, designed to provide rotational capability and engaging capability. A engaging groove is provided on one side of the buckle 281. A locking plate 284 is fixedly connected to the outside of the connecting block 283, designed to provide support and engaging capability. A limiting block 285 is fixedly connected to one side of the locking plate 284, designed to provide limiting capability and prevent the rotating buckle 282 from deviating during engaging. The rotating buckle 282 is rotatably connected to the outside of the locking plate 284, designed to prevent displacement between the first connecting plate 21 and the second connecting plate 22 when the expansion block 26 expands, and designed to provide good limiting capability.

[0036] like Figure 1 and Figure 8 The scraping mechanism 4 includes two sliding rods 41, which are designed to provide sliding capability. The two sliding rods 41 are slidably connected to the inside of the two connecting rods 3. The two sliding rods 41 are fixedly connected to the outside of the limiting plate 43, which is designed to provide limiting capability and prevent the outside of the limiting plate 43 from sliding on the top of the connecting rod 3. The outside of the two sliding rods 41, i.e. the side away from the connecting rod 3, is fixedly connected to a crossbar 42, which is designed to provide lateral support capability. At the same time, it has an annular groove inside to provide sliding space. The bottom of the crossbar 42 is fixedly connected to a scraper 44, which is designed to provide scraping capability so that the surface of the concrete can be scraped after it is poured in, making it flat. The outside of the crossbar 42 is slidably connected to a sliding block 45, which is designed to scrape the outside of the scraper 44, so that the scraper 44 can be cleaned after scraping. The inside of the sliding block 45 is slidably connected to the outside of the scraper 44.

[0037] like Figure 4 , Figure 5 and Figure 7The ejection mechanism 6 includes a hydraulic cylinder 61, which is designed to provide telescopic capability, allowing it to extend and retract within a rectangular groove between the first connecting plate 21 and the second connecting plate 22. The hydraulic cylinder 61 is externally fixedly connected to the top of the support plate 5. The output end of the hydraulic cylinder 61 is fixedly connected to a connecting plate 62, which is designed to provide support capability, providing stable support for the concrete. The first connecting plate 21 is externally fixedly connected to a support rod 64, which is designed to provide support capability. The second connecting plate 22 is externally fixedly connected to a locking block 63, which is designed to provide support capability and, together with the support rod 64, supports the bottom perimeter of the connecting plate 62. The outside of the connecting plate 62 is located on top of the support rod 64 and the locking block 63, and the outside of the connecting plate 62 is in contact with the outside of the first connecting plate 21 and the second connecting plate 22.

[0038] Working Principle: Before the precast component is formed, the first connecting plate 21 and the second connecting plate 22 are first assembled using the engaging assembly 28. Specifically, the rotating buckle 282 and the clamping plate 284 cooperate to fix the first connecting plate 21 to the outer sides of the second connecting plate 22, forming a rectangular space for subsequent concrete pouring. At this time, the expansion block 26 is in its natural state and has not expanded. When the precast component needs to be poured, the heat-conducting column 24 is heated by the heating assembly 23. The heat generated by the heating unit 233 is transferred to the heat-conducting column 24 through the conveying pipe 232 and the connecting pipe 231, and then conducted to the expansion block 26. As the temperature rises, the expansion block 26 thermally expands, and its conical part fits tightly against the conical block 25, pushing the conical block 25 inward, making the connection between the first connecting plate 21 and the second connecting plate 22 tighter, thereby ensuring the stability of the formwork during concrete pouring and preventing the formwork components from loosening or falling off. After the concrete pouring is completed, the precast component is left to form. At this point, the heating component 23 stops operating, and the expansion block 26 gradually cools and contracts. As the expansion block 26 contracts, its thrust on the cone block 25 disappears, and the connection between the first connecting plate 21 and the second connecting plate 22 becomes loose. At this time, the operator can separate it from the clamping plate 284 by operating the rotating buckle 282, thereby achieving quick disassembly of the first connecting plate 21 and the second connecting plate 22, which facilitates subsequent demolding of precast parts and storage and organization of templates.

[0039] During the precast component forming process, the slide rod 41 slides in the groove inside the connecting rod 3, driving the entire scraping mechanism 4 to move. A limiting plate 43 is fixed to the outside of the slide rod 41, sliding on the top of the connecting rod 3 to limit the movement and ensure the stable and accurate trajectory of the slide rod 41. When the slide rod 41 slides, the crossbar 42 moves accordingly, and the annular groove inside the crossbar 42 provides sliding space for the sliding block 45. The scraper 44 is fixed to the bottom of the crossbar 42. As the crossbar 42 moves, the scraper 44 scrapes the surface of the precast component, removing excess concrete and ensuring a smooth surface. During scraping, the sliding block 45 slides outside the crossbar 42, and its interior is slidably connected to the exterior of the scraper 44. The function of the sliding block 45 is to clean the scraper 44, removing residual concrete from its surface and preventing residue buildup from affecting subsequent scraping, thus efficiently completing the cleaning and smoothing of the precast component surface.

[0040] After the preform is formed, hydraulic cylinder 61 begins to operate, its output end extending and retracting. Hydraulic cylinder 61 is fixed to the top of support plate 5, and its extension and retraction pushes connecting plate 62 upwards. During this movement, connecting plate 62 is supported by support rod 64 and locking block 63. Support rod 64 is fixed to the outside of first connecting plate 21, and locking block 63 is fixed to the outside of second connecting plate 22, both providing stable support around the bottom of connecting plate 62. As hydraulic cylinder 61 extends and retracts, connecting plate 62 gradually moves upwards, its exterior tightly fitting against the exteriors of first and second connecting plates 21 and 22. This tight fit ensures that connecting plate 62 can smoothly eject the preform from the mold, preventing damage or deformation during demolding. During ejection, the smooth movement of connecting plate 62 and the supporting action of support rod 64 and locking block 63 allow the preform to detach smoothly from the mold. After the ejection action is completed, the output end of the hydraulic cylinder 61 retracts, and the connecting plate 62 also descends, returning to its initial position, preparing for the next molding and demolding of the preform. Through the extension and retraction of the hydraulic cylinder 61, the smooth movement of the connecting plate 62, and the supporting action of the support rod 64 and the locking block 63, the ejection mechanism 6 can efficiently complete the demolding of the preform, ensuring the integrity of the preform and the demolding efficiency.
