Description

Technical Field

[0001] This utility model relates to the field of prefabricated molded column technology, specifically a casting device for prefabricated molded columns. Background Technology

[0002] Prefabricated formwork columns, as key components in the field of industrialized construction, are widely used in the column casting construction of frame structure buildings. Their core function is to provide temporary forming molds for concrete columns, while also considering ease of installation, structural stability, and cost control. However, with the increasing demands for efficiency and quality in construction, existing prefabricated formwork columns on the market have gradually revealed several technical deficiencies, making it difficult to meet actual construction needs. The formwork column described in application number CN202322421647.9 revolutionizes the traditional reinforced concrete column construction mode with its "no-removal" design. Once the concrete reaches the precast strength, there is no need to remove the formwork, which greatly reduces on-site work and construction waste, meeting the requirements of green construction. Furthermore, its high degree of standardization enables convenient prefabrication in the factory, and its reliable connection with the steel cage can effectively avoid problems such as pouring displacement and grout leakage, ensuring the quality of column formation. However, this formwork column has obvious limitations in practical applications. Its formwork panel is an integral enclosure structure without the design of hinged or disassembled components. It requires large equipment such as cranes for transportation and cannot be installed in narrow spaces such as corridors and elevator shafts, resulting in insufficient adaptability to different scenarios. At the same time, the connection of "formwork panel-embedded gasket-stirrup-expanded mesh" requires precise alignment of multiple components, which requires high operational precision. It is easy to cause repeated adjustments due to misalignment, which increases on-site assembly costs and time and reduces construction efficiency. Based on this, this solution proposes "a casting device for prefabricated molded columns" to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated casting device for molded columns, so as to solve the problem mentioned in the background art that the existing equipment on the market has an integral enclosure structure for the molded plate, without the design of hinged or disassembled components, and the transportation requires large equipment such as cranes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a casting device for prefabricated molded columns, comprising a bearing base, a first baffle, a second baffle, a cover plate, and a first threaded rod; A synchronous traction mechanism is provided above the bearing base. The synchronous traction mechanism includes a cover plate, a first threaded rod, a connecting rod, a pull buckle, a guide rod, and a drive block. The first threaded rod is installed above the cover plate, the pull buckle is installed on the outside of the connecting rod, the connecting rod is installed on the side of the drive block, and the drive block is installed on the side of the first threaded rod.

[0005] As a preferred technical solution of this utility model, a second baffle is fixedly connected to one side of the bearing base, and a first positioning groove is formed on the inner wall surface of the second baffle; Using the above technical solution, a second baffle is fixedly connected to one side of the support base, and a first positioning groove is opened on the inner wall of the second baffle. This design firstly allows the second baffle and the support base to form a stable bottom lateral support structure, providing a precise positioning benchmark for the subsequent installation of the first side plate, the second side plate and the inner lining, avoiding the assembly offset problem caused by the lack of a fixed lateral reference in traditional molded columns, and reducing the time spent on repeated adjustments on site; secondly, the first positioning groove on the inner wall of the second baffle can directly match the snap-fit ​​structure of the inner lining, realizing the rapid positioning and installation of the inner lining and the second baffle without the need for additional measurement marks, reducing the difficulty of operation, while ensuring the positional stability of the inner lining after installation, preventing the inner lining from shifting during the pouring process and affecting the column forming accuracy.

[0006] As a preferred technical solution of this utility model, the left side of the bearing base is hinged to a first side plate, the outer side of the first side plate is provided with reinforcing ribs and two round tube-shaped crossbeams, and a pair of limiting grooves are opened on the outer side of the first side plate. The limiting grooves are right-angled U-shaped structures. The right side of the bearing base is hinged to a second side plate, and the second side plate and the side of the first side plate are both fixedly connected to a second threaded rod, and the structures are the same. The above technical solution involves hinged first side plate on the left side and second side plate on the right side of the support base. Both side plates have identical structures and are fixedly connected to second threaded rods. This split hinge design allows the first and second side plates to be folded and stored, resulting in smaller and lighter individual side plates. This eliminates the need for large equipment like cranes for transport, enabling flexible installation in narrow spaces such as corridors and elevator shafts. This solves the problem of poor adaptability of traditional integral enclosure formwork panels. The reinforcing ribs and circular tubular beams on the outer side of the first side plate significantly enhance its deformation resistance, preventing bulging due to concrete lateral pressure during pouring and ensuring column forming accuracy. The identical structures of both side plates, along with the second threaded rods, eliminate the need to distinguish between left and right side plate specifications, reducing parts classification and identification time. Furthermore, it provides a unified interface for subsequent connection to the first baffle, improving assembly efficiency.

[0007] As a preferred technical solution of this utility model, the second threaded rod is engaged with the first baffle through a guide groove, the second threaded rod is threadedly connected to the threaded cap, and a first baffle is erected between the second threaded rod and the threaded cap. A handle is fixedly connected to the outer surface of the first baffle, and the inner wall of the first baffle is fixedly connected to one side of the inner liner. The other side of the inner liner is engaged with the first baffle through a first positioning groove. The outer side of the inner liner is an injection cavity, and a first membrane shell body is fitted on the outer side of the inner liner. The first membrane shell body is a hollow rectangular structure. Using the above technical solution, the second threaded rod is engaged with the first baffle through a guide groove and then locked with a threaded cap to form a detachable rigid connection structure. Compared with traditional welding or bonding methods, this not only makes assembly and disassembly more convenient but also allows for component reuse, reducing construction costs. The tightness of the threaded connection effectively prevents the first baffle from loosening during pouring, reducing the risk of grout leakage. The inner lining, fixedly connected to the inner wall of the first baffle, engages with the second baffle through a first positioning groove on the other side, creating a closed and stable injection cavity. This ensures the cavity shape remains unchanged during concrete pouring and prevents lining displacement that could lead to column dimensional deviations. The hollow rectangular first membrane shell body fitted outside the inner lining further enhances the compression resistance of the injection cavity, and the smooth surface of the first membrane shell body improves the appearance quality of the formed column, reducing subsequent grinding processes. The handle on the outside of the first baffle facilitates quick handling and positioning of the baffle by construction personnel without the need for additional tools, improving single-person operation efficiency.

[0008] As a preferred technical solution of this utility model, a cover plate is sandwiched between the first baffle and the second baffle. A first threaded rod is rotatably connected to the center position above the cover plate. The first threaded rod is threadedly connected to the drive block. There are two drive blocks symmetrically distributed. A connecting rod is rotatably connected to the outside of the drive block. A pull buckle is rotatably connected to the outside of the connecting rod. The pull buckle is engaged with the first side plate through a limiting groove. Using the above technical solution, the first threaded rod rotatably connected above the cover plate is threadedly connected to two symmetrical drive blocks. When the first threaded rod is rotated, the two drive blocks can move synchronously in opposite directions along the threaded rod. The drive blocks drive the pull buckle to move through the connecting rod, thereby realizing the synchronous opening and closing of the first side plate. This avoids the problem of side plate tilting and misalignment caused by uneven force or asynchronous movement when manually opening and closing the side plate in the traditional way, and greatly improves the assembly accuracy of the first side plate and other components. The pull buckle is engaged with the first side plate through the limiting groove. The limiting groove can limit the movement trajectory of the pull buckle to ensure that the pull buckle always pulls the first side plate in the preset direction, further ensuring the installation stability of the first side plate and reducing the safety hazards caused by the side plate not being fixed firmly during the subsequent pouring process.

[0009] As a preferred technical solution of this utility model, the connecting rod and the buckle are symmetrically distributed in fours, and the first casting interface is fixedly connected to the upper surface of the bearing base cover plate. The first casting interface has a funnel-shaped structure, and there are two symmetrically distributed first casting interfaces. Using the above technical solution, the connecting rods and latches are symmetrically distributed in four parts. The four connecting rods and latches can apply traction force from different positions on the first side plate, making the force on the first side plate more uniform. This avoids the problem of local stress concentration and deformation caused by single or two-point traction, thus extending the service life of the first side plate. At the same time, it also allows the first side plate to fit more tightly with other components, improving the overall sealing performance of the structure. The two symmetrical funnel-shaped first pouring interfaces fixed on the upper surface of the cover plate expand the feed range of concrete pouring, enabling rapid and uniform concrete injection. This avoids the problems of concrete accumulation and air bubble residue caused by slow or uneven feed in traditional single pouring ports, improving the quality and efficiency of column pouring. The funnel-shaped structure also reduces concrete spillage and waste during the pouring process, lowering construction costs.

[0010] As a preferred technical solution of this utility model, a transducer is fixedly connected to the lower surface of the bearing base, and the transducers are arranged in a pair in parallel. Using the above technical solution, a pair of parallel transducers fixed on the lower surface of the support base can generate vibration energy during concrete pouring and transmit it to the support base and the entire mold structure. This causes the concrete inside the mold to be vibrated, effectively expelling air bubbles, reducing internal porosity, and increasing the density of the concrete. At the same time, the vibration can also promote the flow of concrete within the mold, ensuring that the concrete fully fills all corners of the mold and avoiding problems such as local material shortages and incomplete molding caused by poor concrete flow. This improves the structural strength and load-bearing capacity of the column, ensuring the safety and service life of the mold column in the future. The pair of parallel transducers can ensure that the vibration energy is evenly distributed on the support base, avoiding uneven concrete quality caused by insufficient or excessive local vibration intensity.

[0011] As a preferred technical solution of this utility model, a second casting interface is provided above the cover plate. The second casting interface is an inverted trapezoidal structure. The second casting interface is movably connected to the first threaded rod. The second membrane shell body is attached to the bottom of the second casting interface. The first reinforcing bar is exposed on the upper surface of the second membrane shell body. The first reinforcing bar has a U-shaped structure. The second reinforcing bar is exposed on the right side of the second membrane shell body. There are four second reinforcing bars in total, which are distributed in a rectangular shape. The second reinforcing bars of the second membrane shell body penetrate the second baffle. A second positioning groove is provided on the surface of the second baffle. The second membrane shell body is engaged and connected in the second positioning groove. The above technical solution utilizes an inverted trapezoidal second pouring interface above the cover plate. This interface, with its larger feed opening area and gentler inner wall slope, is suitable for concretes of different slumps to avoid feed blockage, reduce material accumulation and waste, and shorten pouring time. It can also be flexibly connected to the first threaded rod, allowing for flexible position adjustment based on on-site operating space and the placement angle of the concrete conveying equipment. This solves the problem of traditional fixed interfaces being difficult to connect in narrow areas, improving scenario adaptability. The U-shaped first reinforcing bar exposed on the upper surface of the second membrane shell enhances the anchorage of the column top to other components. The four rectangular... The distribution of the second reinforcing bar can evenly disperse the vertical load of the column. The second reinforcing bar penetrates the second baffle, and the rigid structure of the second baffle provides lateral restraint for the reinforcing bar, preventing it from shifting during pouring and ensuring that the mechanical properties of the column meet the standards. At the same time, the second positioning groove on the surface of the second baffle engages with the second membrane shell body, which can not only achieve quick and accurate alignment and installation of the second membrane shell body to avoid column size deviation, but also form a closed pouring cavity to reduce concrete leakage and material loss. It can also work together with the second membrane shell body to resist the lateral pressure of concrete, avoid component damage, extend the life of the device, and further improve the column forming accuracy.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This prefabricated molded column significantly improves installation convenience through its split hinge design. The first side plate is hinged to the left side of the support base, and the second side plate is hinged to the right side. The side plates can be folded and stored. Each component is small in size and light in weight, eliminating the need for large equipment such as cranes. It can be flexibly transported and assembled in narrow areas such as corridors and elevator shafts, solving the problem of poor adaptability of traditional integral enclosure molded panels. At the same time, the first and second side plates have the same structure and are both fixed with the second threaded rod, eliminating the need to distinguish between the specifications of the left and right side plates. The handle on the outside of the first baffle also facilitates quick handling and positioning by a single person, further reducing the operation threshold and identification cost.

[0013] 2. In terms of ensuring assembly accuracy, the mold column relies on multi-structure collaboration to avoid repeated adjustments. The second baffle fixed on one side of the support base provides stable lateral support for the first and second side plates. The first positioning groove on its inner wall can directly engage with the inner lining to achieve "immediate installation and positioning", reducing the assembly offset caused by the lack of a fixed benchmark in traditional molds. The first threaded rod on the cover plate is threadedly connected to two symmetrical drive blocks. Rotating the threaded rod can drive the first side plate to open and close synchronously through the connecting rod and pull buckle, avoiding the tilting and misalignment of the side plates caused by uneven force during manual operation, and significantly improving assembly accuracy.

[0014] 3. In terms of structural stability, the mold column reduces the risk of pouring through multiple protections. The second threaded rod engages with the first baffle through the guide groove and forms a detachable rigid connection with the threaded cap, which is more stable than welding and bonding and can effectively prevent the baffle from loosening and leaking grout during pouring. One side of the inner lining is fixed to the first baffle, and the other side engages with the first positioning groove to form a closed injection cavity to prevent the inner lining from shifting. The reinforcing ribs and round tube beams on the outer side of the first side plate enhance the resistance to lateral pressure. Four symmetrically distributed connecting rods and buckles pull the side plate from multiple points to reduce deformation caused by local stress concentration and ensure the overall structural stability.

[0015] 4. This molded column also achieves a dual improvement in casting quality and efficiency. The two symmetrical funnel-shaped first casting interfaces on the cover plate expand the concrete feeding range, enabling rapid and uniform injection and avoiding the problems of concrete accumulation and air bubble residue in traditional single interfaces. The funnel structure also reduces concrete spillage and waste. A pair of parallel transducers on the lower surface of the support base generate uniform vibration energy during casting, which can not only expel air bubbles inside the concrete and reduce porosity, but also promote concrete flow to fill the corners of the mold, avoid local material shortages, and improve the structural strength and molding integrity of the column.

[0016] 5. In terms of economy and environmental protection, this formwork column also has advantages. The components adopt detachable connection methods such as threaded caps and snap-fit ​​structures, which can be disassembled and recycled after construction, reducing the material cost of a single construction. At the same time, it reduces the construction waste generated by the removal of traditional formwork, which is in line with the green construction concept of the construction industry. Compared with some existing "non-removable" formwork, it has more long-term economic and environmental value, and meets the dual requirements of cost and environmental protection in building industrialization.

[0019] 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.

[0020] Please see Figure 1-14 The present invention provides a casting device for prefabricated molded columns. Example 1

[0021] For details, please refer to the following: Figure 1 - Figure 9 It includes a support base 1, a first baffle 2, a second baffle 3, a cover plate 4, a first threaded rod 5, a connecting rod 6, a pull buckle 7, a guide rod 8, a first side plate 9, a second side plate 10, a handle 11, an inner liner 12, a first membrane shell body 13, a limiting groove 14, a first casting interface 15, a drive block 16, a second threaded rod 17, a threaded cap 18, a guide groove 19, and a first positioning groove 20; A synchronous traction mechanism is provided above the support base 1. The synchronous traction mechanism includes a cover plate 4, a first threaded rod 5, a connecting rod 6, a pull buckle 7, a guide rod 8, and a drive block 16. The first threaded rod 5 is installed above the cover plate 4, the pull buckle 7 is installed on the outside of the connecting rod 6, the connecting rod 6 is installed on the side of the drive block 16, and the drive block 16 is installed on the side of the first threaded rod 5.

[0022] The second baffle 3 is fixedly connected to one side of the support base 1, and a first positioning groove 20 is opened on its inner wall. The core value of this design is to build a stable positioning system. On the one hand, the second baffle 3 and the support base 1 form a solid bottom lateral support, providing a precise reference for the subsequent installation of the first side plate 9, the second side plate 10 and the inner lining 12. This avoids the assembly offset caused by the lack of a fixed lateral reference in traditional molded columns, and greatly reduces the time cost of repeated adjustments on site. On the other hand, the first positioning groove 20 can be directly adapted to the snap-fit ​​structure of the inner lining 12, realizing the "measurement-free rapid installation" of the inner lining 12 and the second baffle 3. This reduces the difficulty of operation and can firmly lock the position of the inner lining 12, preventing the inner lining 12 from shifting during concrete pouring and affecting the column forming accuracy. In terms of side panel design, the first side panel 9 and the second side panel 10 are hinged to the left and right sides of the support base 1, respectively. The two side panels have the same structure and are both fixed with the second threaded rod 17. Meanwhile, the outer side of the first side panel 9 is provided with reinforcing ribs, a round tube beam and a right-angle U-shaped limiting groove 14. This solution achieves the triple advantages of "scene adaptation + strength guarantee + efficiency improvement". The split hinge structure allows the side panels to be folded and stored. The individual components are small in size and light in weight, and do not require large handling equipment. They can be flexibly constructed in narrow spaces such as corridors and elevator shafts, solving the pain point of poor scene adaptability of traditional integral enclosure formwork panels. The reinforcing ribs and round tube beams can significantly enhance the deformation resistance of the side panels, resist the lateral pressure during concrete pouring, and prevent the side panels from bulging and affecting the accuracy of the column. The two side panels have the same specifications and are both equipped with the second threaded rod 17, so there is no need to distinguish between left and right, reducing the part identification time. They also provide a unified interface for subsequent connection with the first baffle 2, improving assembly efficiency. For component connection and cavity protection, the second threaded rod 17 engages with the first baffle 2 via the guide groove 19, and is locked in place with the threaded cap 18 to support the first baffle 2. Simultaneously, the first baffle 2 has a handle 11 on its outer side and an inner liner 12 on its inner wall. The other side of the inner liner 12 engages with the first positioning groove 20, and a hollow rectangular first membrane shell body 13 is fitted on its outer side. This design optimizes the construction experience from multiple dimensions: the detachable threaded connection structure is more convenient than traditional welding and bonding, facilitating assembly and disassembly, enabling component reuse, reducing costs, and effectively preventing the first baffle 2 from loosening and leaking grout during pouring; the double fixation of the inner liner 12 and the baffle creates a closed and stable injection cavity, ensuring the cavity shape remains unchanged during concrete pouring and preventing displacement of the inner liner 12 that could cause column dimensional deviations; the first membrane shell body 13 further enhances the cavity's compressive strength, and its smooth surface improves the appearance quality of the formed column, reducing subsequent grinding processes; the handle 11 allows construction personnel to quickly move and position the baffle without additional tools. In terms of synchronous assembly and stability assurance, a cover plate 4 is sandwiched between the first baffle 2 and the second baffle 3. A first threaded rod 5 is rotatably connected at the center line above the cover plate 4. The first threaded rod 5 is threadedly connected to two symmetrical drive blocks 16. The outer side of the drive block 16 is connected to the connecting rod 6, and the outer side of the connecting rod 6 is connected to the pull buckle 7. The pull buckle 7 is engaged with the first side plate 9 through the limiting groove 14. This synchronous traction mechanism effectively solves the drawbacks of traditional manual operation: rotating the first threaded rod 5 can drive the two drive blocks 16 to move synchronously in opposite directions. The first side plate 9 is opened and closed synchronously through the connecting rod 6 and the pull buckle 7, avoiding the side plate tilting and misalignment caused by uneven force and asynchronous movement when manually opening and closing, and greatly improving the assembly accuracy. The limiting groove 14 can limit the movement trajectory of the pull buckle 7 to ensure that it pulls the first side plate 9 in the preset direction, further strengthening the installation stability of the side plate and reducing the safety hazards caused by the side plate not being fixed firmly during pouring. For traction balance and pouring efficiency, four connecting rods 6 and four pull buckles 7 are symmetrically distributed. Two symmetrical funnel-shaped first pouring interfaces 15 are fixed on the upper surface of the cover plate 4. This design optimizes performance from both force and material feeding aspects: the four symmetrical connecting rods 6 and pull buckles 7 can apply traction force from multiple points on the first side plate 9, so that the side plate is subjected to uniform force, avoiding local stress concentration and deformation problems caused by single-point or two-point traction, extending the service life of the side plate, and at the same time making the side plate fit more tightly with other components, improving the overall sealing performance; the funnel-shaped first pouring interface 15 expands the concrete feeding range, enabling rapid and uniform concrete injection, avoiding the problems of concrete accumulation and air bubble residue caused by slow and uneven feeding in traditional single pouring ports, which not only improves the quality and efficiency of column pouring, but also reduces concrete spillage and waste, and lowers construction costs. Example 2

[0023] For details, please refer to the following: Figure 10The difference between this embodiment and embodiment one is that: the transducer 21 is fixedly connected to the lower surface of the support base 1, and the transducers 21 are arranged in a pair in parallel. A pair of parallel transducers 21 fixed to the lower surface of the support base 1 generate vibration energy during concrete pouring and transmit it to the support base 1 and the entire mold structure. This vibration causes the concrete inside the mold to be vibrated, effectively expelling air bubbles, reducing internal porosity, and increasing the density of the concrete. Simultaneously, the vibration promotes the flow of concrete within the mold, ensuring that the concrete fully fills all corners of the mold and preventing issues such as insufficient material or incomplete molding caused by poor concrete flow. This enhances the structural strength and load-bearing capacity of the column, ensuring its safety and service life. The pair of parallel transducers 21 ensures that the vibration energy is evenly distributed on the support base 1, preventing uneven concrete quality caused by insufficient or excessive vibration. Example 2

[0024] For details, please refer to the following: Figure 11 - Figure 14 The difference between this embodiment and embodiment two is that: a second casting interface 22 is opened above the cover plate 4. The second casting interface 22 is an inverted trapezoidal structure. The second casting interface 22 is movably connected to the first threaded rod 5. The second membrane body 23 is attached to the bottom of the second casting interface 22. The first steel bar 25 is exposed on the upper surface of the second membrane body 23. The first steel bar 25 has a U-shaped structure. The second steel bar 24 is exposed on the right side of the second membrane body 23. There are four second steel bars 24 in total, which are distributed in a rectangular shape. The second steel bars 24 of the second membrane body 23 penetrate the second baffle 3. A second positioning groove 26 is opened on the surface of the second baffle 3. The second positioning groove 26 is engaged and connected to the second membrane body 23. The inverted trapezoidal second pouring interface 22, located above the cover plate 4, not only has a larger feed opening area and a gentler inner wall slope, adapting to concretes of different slumps to avoid feed blockage, reduce material accumulation and waste, and shorten pouring time, but it can also be movably connected to the first threaded rod 5. Its position can be flexibly adjusted according to the on-site operating space and the placement angle of the concrete conveying equipment, solving the problem of traditional fixed interfaces being difficult to connect in narrow areas and improving scenario adaptability. The U-shaped first reinforcing bar 25 exposed on the upper surface of the second membrane shell body 23 enhances the connection and anchorage between the top of the column and other components, while the four rectangular second reinforcing bars 24 exposed on the right side... It can evenly distribute the vertical load of the column, and the second reinforcing bar 24 penetrates the second baffle 3. The rigid structure of the second baffle 3 forms a lateral limit on the reinforcing bar, preventing the reinforcing bar from shifting during pouring and ensuring that the mechanical properties of the column meet the standards. At the same time, the second positioning groove 26 on the surface of the second baffle 3 engages with the second membrane shell body 23, which can not only achieve quick and accurate alignment and installation of the second membrane shell body 23 to avoid column size deviation, but also form a closed pouring cavity to reduce concrete leakage and material loss. It can also work with the second membrane shell body 23 to resist the lateral pressure of concrete, avoid component damage, extend the service life of the device, and further improve the column forming accuracy.
