Description

Technical Field

[0001] This invention relates to the field of T-beam casting and forming equipment, and more particularly to a processing and forming device for large precast T-beam templates. Background Technology

[0002] A T-beam is a concrete beam with a roughly T-shaped cross-section, commonly used in bridge construction. Currently, the casting and forming of T-beams often employs long-line molds for one-time casting. Traditional molds rely heavily on manual assembly and disassembly. However, for large precast T-beams (over 20 meters in length), this manual method suffers from low efficiency, difficulty in managing scattered components, and challenges in safety management. Therefore, the application of forming devices that can automatically complete mold assembly and disassembly is gradually increasing. Specific examples include a synchronous hydraulic T-beam formwork construction device (hereinafter referred to as X1) disclosed in invention patent CN108274596A, and a T-beam formwork for road and bridge construction (hereinafter referred to as X2) disclosed in invention patent CN111168822B. In these forming devices, long strip-shaped side templates are often used as the templates for forming the sides of the T-beam. The side templates and supports are designed to slide, and hydraulic cylinders are used as the driving force to move the side templates to complete assembly and disassembly. Currently, this type of forming device has the following drawbacks in use:

[0003] During the processing of large precast T-beams, the side formwork on one side of the T-beam requires multiple hydraulic cylinders to be driven synchronously for demolding. Due to the difference in the bonding force between the side formwork and the T-beam, it is difficult for each hydraulic cylinder to apply force synchronously and evenly when pulling the demolding, which causes the side formwork support to easily deform under uneven demolding force.

[0004] To address this issue, X1 first uses a vibratory demolding cylinder to demold the side mold from the T-beam, and then a synchronous flow divider synchronizes the advance and retreat of the side mold. However, this vibration-based demolding method can easily cause scratches on the surface of the formed T-beam. In some operating conditions, it can also easily cause loosening and shaking between the side mold plate and its support. Furthermore, the installation of the vibration components complicates the structure of the side mold plate. Therefore, this method still has limitations in its application.

[0005] In X2, an electromagnetic power component is added to the inside of the side formwork. During demolding, this component drives the pressure plate to extend, creating a gap between the formwork body and the T-beam before demolding the pressure plate from the T-beam. This reduces the demolding pull force of the piston cylinder. However, this method complicates the electrical structure of the side formwork due to the added electromagnetic component, significantly increasing construction and maintenance costs. Furthermore, the gap between the pressure plate and the formwork body requires a high degree of sealing, making it prone to leaks and grout leakage.

[0006] Therefore, this application proposes a processing and forming device for large precast T-beam templates to solve the problems existing in the prior art. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a processing and forming device for large precast T-beam templates. By setting an elastically deformable support plate inside the support frame, and utilizing the state changes of the connectors, the side templates can be demolded in sections during demolding, thereby reducing the driving force required for demolding and reducing the possibility of uneven stress on the support frame causing deformation. This effectively solves the problems existing in the prior art.

[0008] To address the aforementioned problems, this invention provides a processing and forming device for large precast T-beam templates, comprising: a base, the base including a base body and a bottom mold disposed on the top of the base body; two side mold assemblies, the two side mold assemblies respectively disposed on both sides of the bottom mold, each side mold assembly including a support frame movably disposed on the top of the base body and a side template disposed inside the support frame, the side template being elastically deformable, the side template and the support frame being longitudinally divided into at least two connection areas, the side template having a connector between at least one of the connection areas and the support frame, the connector being telescopically switchable between a forming state and a demolding state; when the connector is in the forming state, the connector retracts to allow the support frame to abut against the side template; when the connector is in the demolding state, the connector can extend to a set distance h, such that when the support frame moves outward a distance greater than h in the forming state, the support frame drives the side template to move outward through the connector.

[0009] Furthermore, the connector includes a plurality of connecting posts spaced apart along the length of the side template and mounted on the side template. A limiting block is provided on the side of each connecting post away from the side template. The connector also includes a support plate disposed on the support frame. The support plate has guide holes for the connecting posts to pass through. The connector further includes a support block movably disposed on the side of the support plate away from the side template. The support block is movable between a forming position and a demolding position. When the support block is in the forming position, it abuts against the limiting block and the support plate, causing the connecting posts to drive the side template to abut against the support frame. When the support block is in the demolding position, the connecting posts extend a predetermined distance h from the support frame toward the side template, and the limiting block abuts against the support block and / or the support plate.

[0010] Furthermore, the connector includes a slide plate that is slidably disposed on the support plate along the length direction of the support plate, and the slide plate is provided with support blocks at positions corresponding to each of the connecting posts; the support blocks are provided with a first support portion and a second support portion along the sliding direction of the slide plate, the thickness of the first support portion is greater than the thickness of the second support portion, and the connector is in a molded state when the slide plate moves the first support portion to the position of the limiting block; the connector is in a demolded state when the slide plate moves the second support portion to the position of the limiting block.

[0011] Furthermore, the side template is provided with a reinforcing strip in the same connection area, and the connecting column is connected to the reinforcing strip; the support block is provided with a constraint hole for the connecting column to pass through, and the sliding plate is provided with a sliding plate hole for the connecting column to pass through. The wall of the constraint hole at the first support position abuts against the connecting column, and the vertical dimension of the constraint hole at the second support position is larger than the dimension at the first support position; the wall of the guide hole abuts against the connecting column in the lateral direction, and the vertical dimensions of both the guide hole and the sliding plate hole are larger than the vertical dimension of the connecting column.

[0012] Furthermore, the limiting block is slidably mounted on the connecting column, and an adjusting nut is threaded onto the end of the connecting column away from the side template of the limiting block.

[0013] Furthermore, the support frame is provided with support ribs between two adjacent connecting areas. When the connector is in the molded state, the support ribs abut against the side template on the side of the reinforcing strip.

[0014] Furthermore, the side template has an upper side mold frame at the bottom of the horizontal section corresponding to the T-beam. The upper side mold frame, away from the side template, is connected to the support frame by the connecting member. The upper edge of the upper side mold frame extends to the upper edge of the horizontal section of the T-beam, and the lower edge extends to the lower edge of the horizontal section of the T-beam. The side template has at least two connecting areas spaced apart on the lower side of the upper side mold frame and at least one connecting area on the upper side, and each connecting area is provided with the connecting member. The h value of the connecting member corresponding to the upper side mold frame and each connecting member on its lower side gradually increases from bottom to top. The h value of the upper side mold frame for the corresponding connecting member is greater than the h value of the connecting member on its upper side.

[0015] Furthermore, the support frame is provided with side frames at both ends of the T-beam along its length, and the inner edge of the side frames is provided with positioning grooves for the side templates to overlap.

[0016] Furthermore, the side template is a Q235B steel plate with a thickness of 5mm or more and 1cm or less.

[0017] Alternatively, the connecting element may be configured as a hydraulic cylinder.

[0018] The beneficial effect of the present invention is that by setting an elastically deformable support plate inside the support frame, the side template can be demolded in sections during demolding by utilizing the state change of the connector, thereby reducing the driving force required for demolding, and thus reducing the possibility of deformation caused by uneven stress on the support frame, effectively solving the problems existing in the prior art.

[0027] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0028] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two connected entities do not establish a connection relationship through an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0031] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] In this invention, such as Figures 1-6As shown, a processing and forming device for large precast T-beam templates is provided, including a base, the base comprising a base body 1, a bottom mold 2 disposed on the top of the base body 1, and two side mold assemblies respectively disposed on both sides of the bottom mold 2. Each side mold assembly includes a support frame 3 movably disposed on the top of the base body 1 and a side template 4 disposed inside the support frame 3. The side template 4 is configured to be elastically deformable. The side template 4 and the support frame 3 are longitudinally divided into at least two connection areas. A connector is provided between the side template 4 and the support frame 3 in at least one of the connection areas. The connector is configured to be telescopic and switchable between a forming state and a demolding state. When the connector is in the forming state, the connector retracts so that the support frame 3 abuts against the side template 4. When the connector is in the demolding state, the connector can extend to a set distance h, so that when the support frame 3 moves outward a distance greater than h in the forming state, the support frame 3 drives the side template 4 to move outward through the connector.

[0033] When the connecting parts are in the molded state, the connecting parts shrink so that the support frame 3 abuts against and supports the side template 4, thereby making the inner surface of the side template 4 (the surface facing the T beam 17) stable and regular in shape, at which time the casting operation can be carried out.

[0034] When demolding is required, some connectors can be switched to the demolding state. By differentiating the h values ​​of different connectors and / or directly fixing the support frame 3 and the side template 4 in some connection areas, when the support frame 3 demolds away from the T beam 17, in the connection area where the support frame 3 is directly connected to the side template 4 (in the case where such a connection exists), the support frame 3 directly drives the side template 4 to separate from the T beam 17. The design is such that when the support frame 3 moves outward to the h value of the corresponding connector, the support frame 3 drives the part of the side template 4 in this connection area to demold from the T beam 17. In this way, the support frame 3 can gradually pull the side template 4 and the T beam 17 apart during the outward movement.

[0035] The improved technical effect of the present invention is that, firstly, during the outward movement of the support frame 3, different connecting areas of the side template 4 can be demolded successively. The part between the first demolded area and the last demolded area is slowly demolded and separated by the elastic deformation of the side template 4. Compared with the overall driving of the side template 4 to demold directly, the resistance that the support frame 3 needs to overcome during the outward movement can be reduced. Even if the support frame 3 is subjected to uneven force in the length direction of the T beam 17 due to the difference in driving force, the uneven force generated by the support frame 3 is small, thereby reducing the occurrence of the working condition of deformation of the support frame 3.

[0036] Secondly, an integral side template 4 is adopted. Compared with the existing patent X2, which divides the side template 4 into a separately driven pressure plate and a template body, the inner surface of the side template 4 of the present invention is more regular, which is conducive to improving the forming quality of T beam 17.

[0037] Thirdly, by driving the support frame 3 to pull the support frame 3 outward, the present invention gradually demolds the side template 4 from the T beam 17 in sections. This not only reduces the power load on the drive component, but also avoids the friction and scratching of the T beam 17 caused by vibration demolding, compared to the vibration demolding method used in X1. It also simplifies the installation structure of the vibration generating mechanism on the side template 4.

[0038] Fourth, the present invention provides demolding power for the side template 4 by driving the driving component of the support frame 3. Compared with the method of using an electromagnetic power component to drive the pressure plate to push out in X2, the present invention does not need to add an additional demolding power component for the side template 4. The structure is relatively simple and the construction and maintenance costs are relatively low.

[0039] exist Figure 1 In the illustrated embodiment, the structure of the connector in this invention is further specified as follows: the connector includes a plurality of connecting posts 5 spaced apart along the length of the side template 4, and a limiting block 6 is provided on the side of the connecting post 5 away from the side template 4; the connector also includes a support plate 7 disposed on the support frame 3, the support plate 7 having guide holes 8 for the connecting posts 5 to pass through; the connector also includes a support block 9 movably disposed on the side of the support plate 7 away from the side template 4, the support block 9 moving between a molding position and a demolding position; when the support block 9 is in the molding position, the support block 9 can abut between the limiting block 6 and the support plate 7, so that the connecting post 5 drives the side template 4 to abut against the support frame 3; when the support block 9 is in the demolding position, the connecting post 5 extends a set distance h from the support frame 3 toward the side template 4, and the limiting block 6 abuts against the support block 9 and / or the support plate 7.

[0040] like Figure 4 and Figure 5 As shown, when the connector is in the molded state, the support block 9 moves to the molded position and abuts between the limit block 6 and the support plate 7. At this time, the connecting column 5 retracts inside the support frame 3, so that the connecting column 5 pulls the side template 4 to the support plate 7. At this time, when casting can be performed inside the side template 4, the support plate 7 can stably support the side template 4.

[0041] When the connector is in the demolded state, such as Figure 6As shown, when the support block 9 moves to the demolding position, the limiting block 6 can move a set distance h toward the T beam 17 and then abut against the support block 9 when the side template 4 and the support frame 3 are in contact. At this time, when the support frame 3 moves further outward, the side template 4 can be pulled outward through the connecting column 5 to demold.

[0042] As can be seen, this invention uses the support block 9 as a "shield" between the support plate 7 and the limiting block 6. By moving the support block 9, the thickness of the "shield" between the limiting block 6 and the support plate is changed, thereby adjusting the extensibility of the connecting column 5 in the direction of the support frame 3 toward the T-beam 17. This design not only simplifies the structure of the connecting parts but also allows the support block 9 to stably support and limit the part during the molding process, maintaining the contact stability between the side template 4 and the support frame 3.

[0043] exist Figure 1 In the illustrated embodiment, regarding the moving structure of the support block 9, more specifically, the connecting member includes a slide plate 10 that is slidably disposed on the support plate 7 along the length direction of the support plate 7. The slide plate 10 is provided with the support block 9 at the positions corresponding to each of the connecting posts 5. The support block 9 is provided with a first support portion 901 and a second support portion 902 along the sliding direction of the slide plate 10. The thickness of the first support portion 901 is greater than the thickness of the second support portion 902. When the slide plate 10 moves the first support portion 901 to the position of the limiting block 6, the connecting member is in a molded state. When the slide plate 10 moves the second support portion 902 to the position of the limiting block 6, the connecting member is in a demolded state.

[0044] like Figure 2 and Figure 5 , Figure 6 As shown, the support block 9 of the present invention is provided with a first support portion 901 and a second support portion 902 of different thicknesses, and a connecting slope is provided between the first support portion 901 and the second support portion 902. When the first support portion 901 moves to the position of the limiting block 6, the connecting column 5 can be moved and retracted in the direction away from the T beam 17. At this time, the support frame 3 abuts against the side template 4 to stabilize the shape of the side template 4. When the second support portion 902 moves to the position of the limiting block 6, since the thickness of the second support portion 902 is smaller, when the support frame 3 starts to move outward, before the side template 4 has been demolded and separated from the T beam 17, the connecting column 5 can extend towards the T beam 17 until the second support portion 902 abuts against the limiting block 6, and then the connecting area of ​​the corresponding connecting column 5 and the side template 4 moves outward and is demolded.

[0045] By setting an inclined surface, the present invention enables the sliding plate 10 to move so that when the support block 9 moves from the position of the second support part 902 corresponding to the position of the limiting block 6 to the position of the first support part 901 corresponding to the position of the limiting block 6, the limiting block 6 can move smoothly.

[0046] The skateboard 10 of the present invention is configured as follows: Figure 2 and Figure 4 As shown, the support plate 7 of the present invention is equipped with a slide rail with grooves, and the two sides of the slide plate 10 are slidably installed in the grooves. Thus, when the state of the connecting member needs to be adjusted, the slide plate 10 can be dragged, thereby moving multiple support blocks 9 to simultaneously switch the positions of the support blocks 9 at multiple connecting posts 5. Furthermore, as... Figure 2 The present invention employs a long strip-shaped sliding plate 10 to switch the state of each connecting column 5 in the same connecting area of ​​the side template 4 together, and the connecting action structure of each connecting area can be conveniently arranged in the longitudinal direction of the support frame 3.

[0047] exist Figure 1 In the illustrated embodiment, regarding the movement of the slide plate 10, more specifically, as... Figure 2 As shown, connecting rings are provided at both outer ends of the slide plate 10. When it is necessary to move the slide plate 10, an external tensioning component can be connected to the rings and the slide plate 10 can be pulled to move. In a preferred embodiment, the tensioning component can be a hand-cranked hoist connected to the connecting rings, and the slide plate 10 can be tensioned by the hand-cranked hoist; or, a portable hydraulic cylinder can be used, with the fixed end of the cylinder abutting against the side frame 18 and the telescopic end connected to the connecting rings, and the slide plate 10 can be moved by the extension of the hydraulic cylinder; or, in an optional embodiment, a fixed hydraulic cylinder can be provided in the support frame 3, and the slide plate 10 can be moved by the hydraulic cylinder.

[0048] The movement of support block 9 is not limited to... Figure 1 In the optional embodiment, the sliding plate 10 moves together with the support block 9. Other methods can also be used, such as slidably arranging each support block 9 on the support plate 7, and moving each support block 9 by a hydraulic cylinder.

[0049] The movable connection between support block 9 and support plate is not limited to linear movement of support block 9. In optional embodiments, the support block can also be rotatably movable with the support plate. Specifically, the support block is rotatably mounted on one side of the connecting column, and the support block has a notch (e.g., a semi-circular notch). When the support block rotates to the position of the notch at the limit block, it is in the demolding position; when the support block rotates to the molded position supporting the limit block, it is in the molded position. Regarding the rotation method of the support block, in specific embodiments, each support block can be rotated by a reduction motor; or, gears can be installed on the support block, and a rack can be used to drive the gears of multiple support blocks to rotate the support block.

[0050] exist Figure 1In the illustrated embodiment, for the structure of the present invention, more specifically, the side template 4 is provided with a reinforcing strip 15 in the same connection area, and the connecting column 5 is connected to the reinforcing strip 15; the support block 9 is provided with a constraint hole 11 for the connecting column 5 to pass through, and the slide plate 10 is provided with a slide plate hole 12 for the connecting column 5 to pass through. The wall of the constraint hole 11 at the first support part 901 abuts against the connecting column 5, and the vertical dimension of the constraint hole 11 at the second support part 902 is larger than the dimension at the first support part 901; the guide hole 8 abuts against the connecting column 5 in the horizontal direction, and the vertical dimensions of both the guide hole 8 and the slide plate hole 12 are larger than the vertical dimension of the connecting column 5.

[0051] like Figure 2 As shown, reinforcing strips 15 are set at the same connection area. By fixing the connecting columns 5 to the reinforcing strips 15, the connection strength between the connecting columns 5 and the side template 4 can be increased. The reinforcing strips 15 also form an integral module at the side template 4, allowing all connecting columns 5 to simultaneously and uniformly move and demold at the reinforcing strips 15 during demolding. This ensures that each connecting column 5 provides a more balanced demolding force to the side template 4 at the reinforcing strips 15, reducing uneven deformation of the side template 4 and maintaining its natural shape stability. When the support block 9 moves to the molding position, the connecting columns 5 provide tension to the side template 4 at the reinforcing strips 15, causing the side template 4 to abut against the support frame 3. The reinforcing strips 15 further improve the uniformity of the tension provided by each connecting column 5 to the side template 4, preventing deformation of the side template 4. The reinforcing strips 15 also stabilize the shape of the side template 4 at the corresponding position.

[0052] Moreover, the advantage of this invention lies in the fact that, at the moment the side template 4 is demolded at the position of the reinforcing strip 15, the side template 4 at the edge of the reinforcing strip 15 is gradually driven to separate from the T beam 17. This invention increases the wall size of the constraint hole 11 at the position of the second support 902, and makes the guide hole 8 and the sliding plate hole 12 larger in vertical dimension than the vertical dimension of the connecting column 5, so that the connecting column 5 can tilt and swing up and down in the guide hole 8, the sliding plate hole 12 and the constraint hole 11. Then, when the side template 4 undergoes elastic deformation during the process of the side template 4 gradually separating from the T beam 17 at the side edge of the reinforcing strip 15, the reinforcing strip 15 can adapt to the deformation of the side template 4 and tilt slightly. At this time, the reinforcing strip 15 can drive the connecting column 5 to tilt.

[0053] When the connecting column 5 of the present invention moves to the position of the first support 901, the wall of the constraint hole 11 at the upper and lower positions abuts against the connecting column 5, which can guide the connecting column 5 to retract precisely, so as to prevent the connecting column 5 from pulling the side template 4 and abutting against the support frame 3 after tilting vertically, thereby preventing deformation. Moreover, in the present invention, by the wall of the guide hole 8 abutting against the connecting column 5 in the lateral direction, it is possible to prevent the connecting column 5 from pulling the side template 4 and abutting against the support frame 3 after tilting in the horizontal direction, thereby preventing deformation.

[0054] exist Figure 1 In the illustrated embodiments, as Figure 2 As shown, the constraint hole 11 is configured at the second support 902 position with the diameter gradually increasing in the direction away from the first support 901, so that the connecting post 5 can be guided to the support position when the constraint hole 11 moves, so that the lateral movement of the connecting post 5 relative to the support block 9 is smoother.

[0055] In a preferred embodiment, more specifically regarding the structure of the present invention, the support frame 3 is provided with a support rib 16 between two adjacent connecting areas. When the connector is in the molded state, the support rib 16 abuts against the side template 4 on the side of the reinforcing strip 15.

[0056] like Figure 2 As shown, in the area where the reinforcing strip 15 directly connects to the side template 4 (excluding the position of the upper side mold frame 14, the second connection area from the bottom), the support plate 7 is provided with support ribs 16 on both the upper and lower sides. There is a gap between the reinforcing strip 15 and the support frame 3 in this part, so that the support ribs 16 can provide stable support force to the side template 4 when the connector is in the molded state, so as to prevent the side template 4 from undergoing large deformation. The gap between the reinforcing strip 15 and the support frame 3 can also be used to provide space for the reinforcing strip 15 to move towards the support frame 3. In some embodiments, the connecting column 5 can be used to provide outward pre-tightening force to the side template 4 in this area, so that the side template 4 can be kept in a taut state before casting, so as to prevent the side template 4 from moving during the casting process.

[0057] exist Figure 1 In the illustrated embodiment, to further specify the structure of the present invention, the limiting block 6 is slidably mounted on the connecting column 5, and an adjusting nut 13 is threadedly engaged at the end of the connecting column 5 away from the side template 4 of the limiting block 6.

[0058] As shown in the figure, by setting the adjusting nut 13, the position of the limiting block 6 can be adjusted by rotating the adjusting nut 13, and thus the tension force of the connecting column 5 on the side template 4 can be adjusted when the connecting part is in the molded state.

[0059] In some scenarios, such as Figure 2 As shown, the side template 4 can also be installed and removed from the inside of the support frame 3 by disassembling the adjusting nut 13 and the limiting block 6, so as to facilitate the maintenance of the side template 4.

[0060] The support frame 3 of the present invention is as follows Figure 1 As shown, it includes multiple sets of columns and beams. The support plate 7 is connected to the columns through a hollow frame structure (with operating holes for nut operation) to form the support frame 3 of the frame structure. When it is necessary to disassemble or assemble the side template 4, the workers can operate between the columns.

[0061] exist Figure 1 In the illustrated embodiment, for the structure of the present invention, more specifically, the side template 4 is provided with an upper side template 14 at the bottom portion corresponding to the horizontal section of the T-beam 17. The upper side template 14 is provided with the connecting member between the side away from the side template 4 and the support frame 3. The upper edge of the upper side template 14 extends to the upper edge of the horizontal section of the T-beam 17, and the lower edge extends to the lower edge of the horizontal section of the T-beam 17. The side template 4 is provided with at least two connecting areas at intervals on the lower side of the upper side template 14 and at least one connecting area on the upper side, and each connecting area is provided with the connecting member. The h value of the connecting member corresponding to the upper side template 14 and each connecting member on its lower side gradually increases from bottom to top. The h value of the upper side template 14 for the corresponding connecting member is greater than the h value of the connecting member on its upper side.

[0062] like Figure 2 and Figure 3 As shown, the horizontal section of T-beam 17 is provided with an upper mold frame 14, which has an approximately triangular cross-section. The upper edge of the upper mold frame 14 extends to the upper edge of the side template 4 in the horizontal section of T-beam 17, and the lower edge extends to the lower edge of the side template 4 in the horizontal section of T-beam 17. In this way, the upper mold frame 14 can be used to shape and support the side template 4 in the horizontal section of T-beam 17, so as to maintain the stability of the shape of the side template 4 in the horizontal section of T-beam 17. The side template 4 forms a reinforcing strip 15 through the upper mold frame 14, which can maintain the side template 4 in the horizontal section of T-beam 17 to stably transmit the lateral tensile force of the support frame 3.

[0063] like Figure 2 and Figure 3As shown, the side template 4 has three connecting areas on the lower side of the upper mold frame 14 and one connecting area on the upper side. By gradually increasing the h value of the connecting parts corresponding to the upper mold frame 14 and each of the connecting parts on its lower side from bottom to top, the following steps can be performed during demolding: the support frame 3 first demolds the part of the side template 4 at the lowest connecting area through the connecting parts, and then gradually demolds from bottom to top until the critical value of the h value of the connecting parts at the position of the upper mold frame 14 is reached. At this time, the part of the side template 4 on the upper side of the upper mold frame 14 has also completed the demolding action. Then, the support frame 3 is moved inward so that the side template 4 and the surface of the T beam 17 are fitted together again, so that the shape of the side template 4 is consistent with the surface of the T beam 17. At this time, the sliding plate 10 can be moved to allow the first support part 901 to support the limiting block 6, completing the shrinkage installation of each connecting part. Then, the support frame 3 is moved outward to complete the demolding separation of the side template 4 at the position of the upper mold frame 14.

[0064] By using this configuration, the present invention can not only separate each area of ​​the side template 4, thereby reducing the driving force and unbalanced force required for the support frame 3 during demolding, but also optimize the demolding process by utilizing the differentiated h values ​​of the connectors in each connecting area, restoring the molded state of the side template 4 and the support frame 3 before demolding is completed.

[0065] exist Figure 1 In the embodiment shown, for the structure of the present invention, the support frame 3 is provided with side frames 18 at both ends of the T beam 17 along its length, and the inner edge of the side frame 18 is provided with positioning grooves 19 for the side template 4 to overlap.

[0066] like Figure 2 As shown, by setting the side frame 18, the edge of the side template 4 can be positioned and overlapped in the positioning groove 19 when the connector is in the molded state, so as to use the side frame 18 to stably support the edge of the template. When the support frame 3 moves outward for demolding, the side frame 18 is completely separated from the side template 4 to reduce interference with the demolding of the side template 4.

[0067] exist Figure 1 In the illustrated embodiments, as Figure 1 and Figure 2 As shown, the side frame 18 is hollowed out at the position corresponding to the end of the skateboard 10, so as to facilitate the traction action of the end of the skateboard 10.

[0068] In a preferred embodiment, specifically regarding the structure of the present invention, the side template 4 is a Q235B steel plate with a thickness greater than or equal to 5 mm and less than or equal to 1 cm. This allows the side template 4 to be formed by bending the steel plate, which is convenient for processing, and the steel plate is durable, stable, and easy to demold. Furthermore, in the processing of long, large T-beams 17, the side template 4 can be formed by welding multiple separate templates together, further simplifying the processing.

[0069] As an option, the side formwork 4 can also be made of other elastically deformable materials, such as side formwork 4 made of polyurethane composite board.

[0070] exist Figure 1 In the illustrated embodiment, the connector is formed by combining components such as a sliding plate 10, a support block 9, a connecting column 5, and a limiting block 6 to complete the extension and retraction of the connecting column 5 relative to the support frame 3. This is not a limitation of the present invention. In optional embodiments, the connector can also be configured as a hydraulic cylinder. Specifically, hydraulic cylinders can be respectively installed at the positions of each connecting column 5 in the corresponding illustrated embodiment, with one end of each hydraulic cylinder connected to the support frame 3 and the other end connected to the side template 4.

[0071] exist Figure 1 In the illustrated embodiment, a further explanation of the structure of the present invention is that, regarding the movable arrangement of the support frame 3 on the base, those skilled in the art can flexibly choose existing methods of cooperation between the side template 4 support frame 3 and the base, such as the method shown in the accompanying drawings. The bottom of the support frame 3 is slidably connected to the base, a slider is provided at the bottom of the support frame 3, a slide rail is provided on the base corresponding to the slider position, and a hydraulic cylinder is provided between the support frame 3 and the base, using the hydraulic cylinder to drive the support frame 3 to slide. It should be understood that the connection method between the support and the base in the accompanying drawings is not intended to limit the present invention regarding the "movable arrangement of the support frame 3 and the base." In optional embodiments, other alternative methods can be used, such as providing a slide rail at the bottom of the support frame 3 and a slider at the corresponding slide rail position on the base; for example, the bottom of the support frame 3 and the base are connected by a hinge; for example, in the accompanying drawings, the support frame 3 and the base are horizontally slidingly fitted, and alternatively, the slide rail can be set to extend obliquely downwards outwards.

[0072] Regarding the movement driving method of support frame 3, in Figure 1 In the illustrated embodiment, a drive cylinder is provided on the outer side of the support frame 3. The drive cylinder can be connected to an external fixed bracket so that the drive cylinder can move the support frame 3. In an optional embodiment, the drive cylinder can also be connected to the base body 1.

[0073] In the appendix Figure 1To demonstrate this more clearly, only one end of the entire installation is shown. Figure 2 In the middle, the connecting structure at the end of part of the skateboard 10, part of the frame structure at the connection position between the support plate 7 and the column, and one of the side frames 18 are removed and shown.
