Description

Technical Field

[0001] This application relates to the field of track beam manufacturing technology, and in particular to a curved beam forming system. Background Technology

[0002] In the field of rail transit engineering, the forming process of track beams has a crucial impact on the stability, safety, and construction efficiency of the line. Currently, track beams generally employ a split-type forming process, where the U-shaped track beam is prefabricated first, and then the track surface (wing plates) is formed by on-site casting. This split-type construction method, to a certain extent, meets the construction requirements of track beams.

[0003] For curved track beams, their structure needs to meet specific curvature radii and spatial alignment requirements to ensure smooth train operation on curved sections. However, the main body of the track beam (such as the U-beam) and the flanges need to have the same curved shape on curved sections to ensure the uniformity of stress and stability of the overall structure. But due to the fixed dimensions of prefabricated components and the limitations of on-site casting precision, achieving a precise match between the curved shape of the main body and the flanges is quite difficult. Currently, the industry has to rely on a split-type molding process, that is, first prefabricating the U-beam main body with a specific curvature, and then casting the flanges or track surface through on-site measurement and adjustment to fit the design curve as closely as possible.

[0004] This split-type molding process has several technical drawbacks: First, the interface between precast components and cast-in-place parts is prone to stress concentration areas, leading to a decrease in the overall structural integrity and potential problems such as cracking and deformation during long-term operation, affecting the service life of the track beam and train safety. Second, on-site casting requires separate curvature measurement and formwork for each curve segment, making the construction process complex and time-consuming, increasing project costs and schedule pressure. In addition, due to the separation of precast and cast-in-place processes, it is difficult to accurately control the consistency of the curves, which may lead to deviations between the actual alignment of the track beam and the design parameters, affecting the smoothness of train operation.

[0046] A curved beam forming system according to an embodiment of the first aspect of this application, such as Figures 1 to 7 As shown, the curved beam forming system includes a bottom mold 1, side molds 2, and wing molds 3. The side molds 2 are located on both sides of the bottom mold 1, and the wing molds 3 are located above the side molds 2. The inner edge of the wing molds 3 overlaps with the side molds 2. The bottom mold 1, side molds 2, and wing molds 3 together form a cavity with an upper opening, which is used for pouring concrete to form the curved beam 8. The side molds 2 can move horizontally to adjust the curvature of the main body 81 of the curved beam 8 at various points along its length. The wing molds 3 include multiple template units 31, which are spliced ​​along the length of the curved beam 8 to make the wing molds 3 form a polygonal shape that matches the curved beam 8. The curved beam can be a curved track beam.

[0047] The curved beam 8 includes a main body 81 (U-shaped beam) and a flange 82 (track surface).

[0048] It should be noted that the curved beam forming system provided in this application may also include an inner mold mechanism for forming a hollow channel inside the curved beam 8. The inner mold mechanism may adopt an existing template form, which will not be described in detail in this application.

[0049] The curved beam forming system of this application overcomes the technical bottleneck of traditional split forming processes by coordinating the horizontally movable side mold 2 with the modularly spliced ​​wing plate mold 3. This allows for the integrated forming of curved beam segments with different curvatures, meeting the manufacturing requirements of curved beams with varying curvatures. The wing plate mold 3 uses multiple template units 31 spliced ​​along its length, approximating the designed curve shape through a zigzag combination. This ensures the synchronization of curvature changes between the wing plate 82 and the main body 81, while also reducing the difficulty of surface processing through modular structure. The wing plate mold 3, formed by the splicing of multiple template units 31, allows for real-time adjustment of the curvature of the main body 81 along its length according to the design parameters of the curved beam 8. It is widely applicable to curved beam segments with different curvatures and bending shapes, demonstrating strong practicality. Furthermore, it allows the bending shape of the main structure during concrete pouring to adapt to more complex curved lines, avoiding matching deviations caused by fixed curvature in precast components.

[0050] The aforementioned integrated casting scheme eliminates the interface between prefabricated components and cast-in-place modules in existing technologies, significantly improving the structural integrity of the curved beam 8, effectively avoiding stress concentration and cracking risks. It also eliminates the cumbersome prefabrication, transportation, and secondary casting processes inherent in separate manufacturing, greatly reducing the construction cycle. Furthermore, the coordinated and adjustable design of the side formwork 2 and the wing plate formwork 3 enables precise control of the geometric parameters of the curved beam 8, ensuring a high degree of consistency between the actual track beam alignment and design parameters, providing structural assurance for the smoothness and safety of train operation.

[0051] The number of template units 31 can be adjusted according to actual needs. When the accuracy of the curve beam 8 is required to be high, the number of template units 31 can be increased appropriately so that the broken line formed by splicing the template units 31 fits the preset curve better.

[0052] An elastic sealing structure (such as an elastic rubber pad or sprayed foam adhesive) can be installed at the joint of adjacent template units 31 to avoid grout leakage at the joint.

[0053] According to one embodiment of this application, such as Figure 1 , Figure 5 and Figure 6 As shown, the curved beam forming system also includes a gantry 4 and a support mechanism 5. One end of the support mechanism 5 is connected to the gantry 4, and the other end is fixed to the bottom mold 1, the side mold 2, or the wing plate mold 3.

[0054] The gantry 4 and support mechanism 5 provided in this application constitute the basic load-bearing structure of the curved beam forming system. The gantry 4, as the overall support frame, provides a reliable installation benchmark for the bottom formwork 1, side formwork 2, and wing plate formwork 3 through a rigid structure, ensuring that each formwork maintains positional accuracy under load during concrete pouring and avoiding deviations in the geometric parameters of the curved beam 8 due to support deformation. The support mechanism 5 adopts an adjustable connection design, with one end rigidly connected to the gantry 4, and the other end fixed or hinged to the bottom formwork 1, side formwork 2, and wing plate formwork 3 respectively according to the functional requirements of different formworks. This satisfies the guiding stability of the side formwork 2 during horizontal movement and allows for fine-tuning of the angle and position of the wing plate formwork 3 during splicing, forming a multi-dimensional collaborative formwork positioning system. This ensures that the entire curved beam forming system maintains the relative positional accuracy between the formworks during the construction of complex curved lines, providing a reliable mechanical support foundation for the integrated pouring of the curved beam 8 body and the wing plate 82, while also improving safety and ease of operation during construction.

[0055] According to one embodiment of this application, such as Figure 1 As shown, the gantry 4 includes a crossbeam 41, a vertical beam 42 and a longitudinal beam 43. The vertical beam 42 is vertically installed on both sides of the side mold 2. The crossbeam 41 is fixed to the top of the vertical beam 42. The longitudinal beam 43 is connected to the vertical beam 42 and extends along the length of the curved beam 8.

[0056] The gantry 4 employs a three-dimensional frame structure consisting of crossbeams 41, vertical beams 42, and longitudinal beams 43, forming a reliable support system. The vertical beams 42 are vertically arranged on both sides of the side mold 2, serving as core load-bearing components. Through a rigid connection with the side mold 2, they provide vertical support reaction force while limiting the lateral displacement of the side mold 2 during horizontal movement, ensuring motion accuracy during curvature adjustment. The crossbeams 41 are fixed to the top of the vertical beams 42 and can be used to suspend related mechanisms (such as the positioning mechanism 7). The longitudinal beams 43, acting as reinforcing beams, extend along the length of the curved beam 8 and connect with the vertical beams 42, forming a continuous longitudinal support, ensuring the entire gantry 4 maintains rigidity continuity along the linear direction of the curved beam 8.

[0057] The crossbeams 41, vertical beams 42 and longitudinal beams 43 can be connected by flange bolts to facilitate the easy disassembly and assembly of each component, making transportation and on-site assembly convenient.

[0058] According to one embodiment of this application, such as Figure 1 As shown, the support mechanism 5 includes a first support component 51, one end of which is connected to the gantry 4 and the other end is connected to the side mold 2; the first support component 51 is configured to fix the side mold 2 and allow the side mold 2 to move in the horizontal direction.

[0059] One end of the first support component 51 is rigidly connected to the gantry 4. Through a high-strength connection structure, the lateral concrete load borne by the side mold 2 is evenly transferred to the gantry 4 frame, ensuring the entire molding system maintains structural rigidity during pouring and preventing localized deformation due to load concentration. The other end of the first support component 51 is connected to the side mold 2 in a horizontally movable manner, allowing the side mold 2 to adjust its curvature in the horizontal direction. The first support component 51 provides a stable support reference for the side mold 2 and allows it to adjust its horizontal displacement at various positions in real time according to the design parameters of the curved beam 8, controlling the curvature change of the main body 81 in the length direction.

[0060] In practical applications, rubber damping pads or spring dampers can be installed at the connection between the first support component 51 and the side formwork 2 to absorb the vibration energy during the concrete vibration process, avoid high-frequency vibration of the formwork caused by rigid connection, and compensate for the structural thermal expansion and contraction deformation caused by temperature changes, so as to ensure the long-term stability of the side formwork 2 position.

[0061] According to one embodiment of this application, the first support assembly 51 includes a first telescopic rod, the length of which is adjustable to allow the side mold 2 to move horizontally (not shown in the figure); or, as... Figures 1 to 3As shown, the gantry 4 is provided with a threaded seat 44. The first support assembly 51 includes a connecting rod 511 and a rotary joint 512. The connecting rod 511 and the rotary joint 512 are rotatably connected so that the connecting rod 511 can rotate along its own axis. The outer surface of the connecting rod 511 is provided with an external thread that mates with the threaded seat 44. The threaded seat 44 rotates to drive the first support assembly 51 to move along its own length direction, so that the side mold 2 can move in the horizontal direction.

[0062] In this application, the first support component 51 provides a reliable mechanical drive scheme for the horizontal movement of the side mold 2 through two adjustable structural designs. When the first telescopic rod is used, the length of the first support component 51 can be adjusted according to the curvature change of the curved beam 8, thereby adjusting the position of the side mold 2 in real time. The horizontal displacement of the side mold 2 can be precisely controlled by the telescopic movement of the first telescopic rod, so that the bending shape of the main body 81 can flexibly adapt to different line requirements.

[0063] like Figures 1 to 3 As shown, when using the threaded seat 44, the structure of the threaded seat 44 and the external thread of the connecting rod 511 utilizes the high-precision characteristics of the thread transmission to convert the rotational motion of the connecting rod 511 into the linear motion of the first support component 51. By controlling the rotation angle of the connecting rod 511, the displacement of the side mold 2 can be precisely adjusted.

[0064] Both of the above structures ensure that the side mold 2 maintains stable guidance during horizontal movement, avoiding the problem of curvature distortion of the main body of the curved beam 8 due to displacement deviation. Compared with the traditional manual adjustment method, this design significantly improves the accuracy and efficiency of the side mold 2 position adjustment through standardized control of mechanical transmission, eliminates human operation errors, and ensures that the curvature of each segment of the main body 81 of the curved beam 8 strictly conforms to the design parameters. This guarantees the overall geometric accuracy of the curved beam 8 during integral casting and effectively solves the curve matching problem of split molding in the existing technology.

[0065] In some cases, a displacement sensor (such as a grating ruler or displacement sensor) can be embedded in the first support component 51 to collect the position data of the side mold 2 in real time and feed it back to the control system to form a closed-loop adjustment circuit, automatically compensate for displacement deviations caused by mechanical wear or load changes, and ensure that the curvature adjustment accuracy always meets the design requirements.

[0066] According to one embodiment of this application, such as Figure 5 As shown, the support mechanism 5 includes a second support component 52. One end of the second support component 52 is slidably mounted on the crossbeam 41, and the other end is connected to the template unit 31 to fix the template unit 31 in a preset position.

[0067] The second support component 52 is slidably connected to the crossbeam 41 and fixes the template unit 31, providing crucial support for the precise positioning and flexible adjustment of the wing plate mold 3. One end of the second support component 52 slides with the crossbeam 41, allowing it to move left and right relative to the curved beam 8 on the horizontal plane to accommodate the splicing requirements of multiple template units 31 of the wing plate mold 3, enabling each template unit 31 to be quickly positioned in space according to the angle of the designed curve. The other end of the second support component 52 is connected to the template unit 31, fixing the template unit 31 in a preset position to ensure the positional accuracy of the wing plate mold 3 during concrete pouring and avoid displacement deviations caused by vibration or load. Through mechanical sliding and accurate positioning, the template unit 31 is quickly positioned and stably fixed in three-dimensional space, ensuring a high degree of consistency between the overall folded shape of the wing plate mold 3 and the design line of the curved beam 8. Meanwhile, the combination of sliding installation method and modular design of template unit 31 enables the wing plate mold 3 to easily adapt to the construction of curved beams 8 with different radii of curvature, significantly improving the versatility and construction efficiency of the forming system, and providing a reliable support solution for the high-precision forming of the wing plate 82 part of the curved beam 8.

[0068] According to one embodiment of this application, such as Figure 1 As shown, the second support assembly 52 includes a roller assembly 521, a second telescopic rod 522, and a support column 525. One end of the second telescopic rod 522 is connected to the roller assembly 521, and the other end is hinged to the support column 525. The roller assembly 521 is slidably mounted on the crossbeam 41, and the support column 525 abuts against the template unit 31.

[0069] The sliding engagement between the roller assembly 521 and the crossbeam 41 enables convenient movement of the support assembly along the length of the crossbeam 41, while the low-friction roller structure reduces movement resistance. The length of the second telescopic rod 522 is adjustable, facilitating the support column 525 to abut against or separate from the template unit 31, thus simplifying the installation and disassembly of the template unit 31. The support column 525 is hinged to the telescopic rod, allowing the support column 525 to abut against the template unit 31 by rotation and then be fixed in place, providing reliable support for the template unit 31. The structure of the second support assembly 52 solves the problems of low positioning accuracy and difficult angle adjustment in traditional wing plate mold 3 support. Through mechanical linkage, it achieves rapid positioning and reliable fixing of the template unit 31, ensuring the consistency of the overall line of the wing plate mold 3 and improving the convenience of template installation and disassembly during construction, providing a stable support foundation for the high-precision forming of the wing plate 82 part of the curved beam 8.

[0070] In practical applications, lateral guide wheels or limiting rails can be added to the roller assembly 521 to constrain the linear movement trajectory of the roller assembly 521 along the crossbeam 41, avoiding deviation caused by lateral forces and improving the positional accuracy during the sliding process. A wear-resistant rubber layer can also be applied to the surface of the roller assembly 521 to increase the contact friction with the crossbeam 41 and prevent accidental sliding due to vibration during the pouring process.

[0071] According to one embodiment of this application, such as Figure 1 As shown, the second support assembly 52 also includes a third telescopic rod 523, one end of which is connected to the vertical beam 42, and the other end is hinged to the other end of the second telescopic rod 522 to restrict the second telescopic rod 522 to a preset position.

[0072] One end of the third telescopic rod 523 is rigidly connected to the vertical beam 42, serving as a fixed support base point. The other end is hinged to the second telescopic rod 522, forming a positional constraint on the end of the second telescopic rod 522. This effectively limits its displacement and deformation under concrete pouring loads, ensuring that the formwork unit 31 remains stable in the preset position. The third telescopic rod 523 provides the power for the second telescopic rod 522 to move left and right, and provides the support force to keep the second telescopic rod 522 stationary in the horizontal direction, thereby improving the overall rigidity of the wing plate formwork 3 support system.

[0073] According to one embodiment of this application, such as Figure 1 As shown, the second support assembly 52 also includes a fourth telescopic rod 524. One end of the fourth telescopic rod 524 is connected to the side mold 2, and the other end is connected to the free end of the support column 525, so that the free end of the support column 525 abuts against the template unit 31.

[0074] The fourth telescopic rod 524 added to the second support component 52 in this application forms a reliable support for the support column 525 by connecting the side mold 2 and the free end of the support column 525, thereby achieving reliable support for the template unit 31.

[0075] The fourth telescopic rod 524 is connected to the side formwork 2, eliminating the need for additional support frame foundations near the curved beam 8, reducing the number of components and improving the fixing reliability of the fourth telescopic rod 524.

[0076] Furthermore, the design of the fourth telescopic rod 524 solves the error problem caused by the independent adjustment of the side mold 2 and the wing plate mold 3: the mechanical linkage of the fourth telescopic rod 524 enables the synchronous transmission of curvature parameters between the main body 81 and the wing plate 82, avoiding the problem of line deviation caused by asynchronous adjustment between the two. Specifically, when the side mold 2 moves horizontally due to the curvature change of the main body 81 of the curved beam 8, the fourth telescopic rod 524 can move the wing plate mold 3 synchronously while remaining stationary, thereby matching the angle of the broken line at each splice of the wing plate mold 3 with the bending shape of the main body 81, thus achieving a high degree of consistency in the overall line of the curved beam 8 during the integrated casting process.

[0077] Of course, after the fourth telescopic rod 524 drives the wing plate mold 3 to move synchronously, the wing plate mold 3 can be finely adjusted according to specific needs.

[0078] It should be noted that each of the aforementioned telescopic rods can be fixed after being adjusted to the required length to provide reliable support. Hydraulic locks or electromagnetic locking structures can be used, which will not be elaborated upon in this application.

[0079] According to one embodiment of this application, such as Figure 4 As shown, the wing plate mold 3 also includes a vertical plate 32, which is disposed on the outside of the template unit 31 and extends in the vertical direction; the height of the vertical plate 32 is set to be the same as the thickness of the wing plate 82 of the curved beam 8.

[0080] The vertical plate 32 extends vertically along the outside of the formwork unit 31 and its height is consistent with the thickness of the flange 82, thereby limiting the vertical dimension (thickness) of the flange 82. The coordinated arrangement of the vertical plate 32 and the formwork unit 31 forms a lateral constraint on the concrete of the flange 82.

[0081] The vertical plate 32 can be fixed to the outside of the template unit 31 by means of bolts or other methods. There can be multiple vertical plates 32, and the length of each vertical plate 32 can be the same as the length of a single template unit 31; or there can be only one vertical plate 32, and the length of the single vertical plate 32 is equal to the sum of the lengths of all the template units 31 after splicing.

[0082] According to one embodiment of this application, such as Figure 1 , Figure 5 and Figure 6 As shown, the curved beam forming system also includes a traveling mechanism 6. The bottom mold 1 is installed on the traveling mechanism 6. The traveling mechanism 6 is configured to transport the curved beam 8 to a preset position (such as a hoisting station) after the curved beam 8 is demolded.

[0083] The integrated design of the traveling mechanism 6 provides automated transportation for the forming process of the curved beam 8. After the curved beam 8 is demolded, the traveling mechanism 6 transports the bottom mold 1 and the curved beam 8 to the preset position, achieving a seamless connection between the forming and transportation processes. This reduces the risk of structural collisions or deformations caused by manual handling or traditional lifting equipment, effectively ensuring the quality of the finished curved beam 8. At the same time, the automated transportation of the traveling mechanism 6 reduces manual intervention after demolding, eliminating the cumbersome secondary lifting and positioning processes, significantly shortening the cycle from forming to storage or installation of the curved beam 8, and improving overall construction efficiency.

[0084] The collaborative design of the traveling mechanism 6 with components such as the bottom mold 1 and side mold 2 enables the molding system to have assembly line operation capabilities, which can meet the needs of prefabricated component factory production. Through the parallel operation of multiple sets of traveling mechanisms 6, the mass production of curved beams 8 can be realized, meeting the requirements of modern rail transit engineering for the efficiency and standardization of large-scale component manufacturing.

[0085] According to one embodiment of this application, such as Figure 1 , Figure 5 and Figure 6 As shown, the curved beam forming system also includes a positioning mechanism 7. One end of the positioning mechanism 7 is fixed to the crossbeam 41, and the other end extends to the upper surface of the curved beam 8. The positioning mechanism 7 is configured to fix the embedded part in a preset position within the curved beam 8. The positioning mechanism 7 is fixed to the crossbeam 41 by a clamping plate and can move laterally left and right on the crossbeam 41.

[0086] The positioning mechanism 7, through its rigid connection with the crossbeam 41 and its structural design extending to the upper surface of the curved beam 8, provides reliable mechanical support for the precise positioning of the embedded parts. One end of the positioning mechanism 7 is fixed to the crossbeam 41, utilizing the overall rigidity of the gantry 4 to form a stable reference fulcrum. The other end, through an adjustable extension structure (such as a telescopic rod or guide arm), precisely reaches the target position on the upper surface of the curved beam 8, ensuring that the embedded parts are fixed to the design coordinates before concrete pouring. This structural design effectively solves the problems of traditional construction where the positioning of embedded parts relies on manual measurement and is easily affected by pouring vibrations, leading to displacement. Through the standardization and rigid constraints of mechanical positioning, the positional deviation of the embedded parts is controlled within a small range, ensuring the accuracy requirements of subsequent processes such as track fastener installation and cable laying. Simultaneously, the integrated design of the positioning mechanism 7 and the gantry 4 allows the fixing of embedded parts to be carried out simultaneously with the formwork erection process, avoiding repeated adjustments of separate positioning devices and significantly improving construction efficiency. In addition, the structural design extending to the concrete surface makes it easy for construction personnel to visually verify the position of the embedded parts. Combined with visual scale markings or laser alignment devices, it further reduces the difficulty of operation and provides a systematic solution for the high-precision installation of complex embedded parts inside the curved beam 8.

[0087] The aforementioned positioning mechanism 7 can be used to pre-embed the magnetic levitation induction plate 83 or the sleeve.

[0088] For example, the curved beam forming system of this application can form a curved beam 8 with a length of 25m.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
