Description

Technical Field

[0001] This invention relates to the field of precast double-T beam casting side mold technology, and in particular to a hydraulic side mold tooling for casting in a precast beam ring production line. Background Technology

[0002] Precast beams are beams that are prefabricated in a factory and then transported to the construction site for installation and fixing according to the design requirements. Double-T beams utilize an integrated outer and bottom mold system for casting. However, existing casting molds have the following problems during use: After the concrete is poured, the concrete strength and modulus of elasticity must reach the specified values ​​before tensioning can begin. Because the traditional method is that the formwork cannot be removed before tensioning, the actual strength of the beam concrete cannot be controlled, which affects the tensioning quality. When precasting shorter beams, there is a distance between the beam end and the formwork end. However, the diameter of a typical tensioning jack is larger than the width of the precast beam rib, causing the jack to malfunction. The tensioning problem can only be solved by using an extended sleeve or adding a pad, which makes tensioning inconvenient.

[0003] Therefore, a hydraulic side mold tooling for casting precast beams in a circular production line is proposed to solve the above problems. Summary of the Invention

The upper end of the adjusting rod passes through the mounting cylinder and the side mold body in sequence and is flush with the top surface of the side mold body.

[0008] Preferably, the indicating structure further includes a connecting block fixedly connected to the surface of the side mold body. One end of the connecting block extends above the adjacent side mold body, and a trigger cavity is provided at the bottom of the connecting block. The trigger cavity is coaxially arranged with the adjacent adjusting rod. An indicator rod is slidably connected to the inner wall of the trigger cavity. An indicator line is provided on the surface of the indicator rod, and the upper end of the indicator rod passes through the connecting block.

[0009] Preferably, a top rod is slidably connected inside the adjusting rod, a fourth spring is fixedly connected between the lower end of the top rod and the inner wall of the adjusting rod, the upper end of the top rod extends through the adjusting rod, and two symmetrically distributed wedge surfaces are opened on the top of the top rod.

[0011] Preferably, the mounting cavity is provided with two symmetrically distributed sealing plates. The surface of the sealing plate is fixedly connected to the end of the adjacent telescopic rod away from the pressure plate.

[0015] The beneficial effects of this invention are: After the concrete pouring is completed, the side formwork on both sides can be separated from the bottom formwork using hydraulic push rods and side formwork structures. The double T-beam with the concrete poured can then be transferred to the next processing point via a moving platform. This facilitates circular production line processing. At the same time, the separation of the side formwork body makes it easier to test the concrete strength and modulus of elasticity of the double T-beam. It also facilitates the testing of the concrete strength of the beam before tensioning, guiding the tensioning construction and thus affecting the tensioning quality. When prefabricating shorter beams, there is a certain distance between the beam end and the formwork end. By separating the side formwork bodies on both sides, it is possible to avoid the traditional mold prefabrication beam rib width being less than the jack width, which would prevent the jack from working properly. This also avoids the need to use extended sleeves or add pads to solve the tensioning problem with traditional molds, reducing the waste of prestressed steel strands. After the pouring is completed, the side formwork body is separated from the bottom formwork by the hydraulic push rod, so that the moving platform can transfer the bottom formwork and double T beam to the next process for processing, thereby reducing the investment of formwork, reducing the planned area of ​​the beam yard and the corresponding equipment cost investment, while improving the production efficiency of precast beams. During the connection between the side mold body and the bottom mold, the bottom mold can be used to push the trigger plate, thereby injecting the hydraulic oil inside the liquid storage shell into the installation cylinder under the action of the indicator structure. Under the combined action of the adjusting rod and the push rod, the indicator rod can be pushed out of the connection block. The workers can judge whether the side mold bodies are aligned by passing through the indicator line during the process of applying the release agent to the surface of the side mold body and the bottom mold, so as to avoid the situation where there is misalignment between the side mold bodies 201 that affects the pouring. With the cooperation of the connecting groove and the fixing structure on the connecting frame, the connection stability between the side mold body and the bottom mold can be enhanced. At the same time, the cooperation between the limiting block and the limiting groove can prevent the threaded sleeve from turning back and loosening during the vibration process.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In practical implementation: such as Figure 1-10As shown, a hydraulic side mold tooling for casting precast beams in a circular production line includes: a movable platform 1, a bottom mold 101 fixedly connected to the top of the movable platform 1, and side mold structures 2 evenly distributed on both sides of the movable platform 1; each side mold structure 2 includes two mounting blocks 202 respectively disposed on both sides of the movable platform 1; two guide blocks 204 symmetrically distributed are fixedly connected to the top of the mounting blocks 202, and a hydraulic push rod 203 located between the two guide blocks 204 is disposed on the top of the mounting blocks 202; the output shaft of the hydraulic push rod 203 is fixedly connected to a side mold body 201, the side mold body 201 has an L-shaped cross-section, and two mounting brackets 205 symmetrically distributed are fixedly connected to the inner side of the side mold body 201. The mounting bracket 205 has an L-shaped cross-section, and one end of the mounting bracket 205 extends to the outside of the side mold body 201. The side mold body 201 has a mounting cavity on the side near the bottom mold 101. An auxiliary mechanism 3 is included; the auxiliary mechanism 3 includes a sealing structure 31 disposed inside the side mold body 201, which improves the sealing effect at the connection between the side mold body 201 and the bottom mold 101. The auxiliary mechanism 3 also includes an indicator structure 32 disposed on the surface of the side mold body 201, which indicates whether two adjacent side mold bodies 201 are flush. A fixing structure 4 is disposed above the bottom mold 101, which enhances the limiting effect on the position of the side mold body 201. Before pouring, the bottom mold 101 is moved between the side mold structures 2 on both sides using the moving platform 1, and the hydraulic push rod 203 is activated. Under the action of the hydraulic push rod 203, the side mold body 201 is moved closer to the bottom mold 101, so that both ends of the bottom mold 101 are inserted into the mounting cavities on the side mold bodies 201 on both sides, thus completing the installation between the side mold structures 2 and the bottom mold 101. Then, the fixing structure 4, together with the mounting bracket 205, fixes the position of the side mold bodies 201 on both sides, reducing mold bulging and improving the pouring quality. After the fixing structure 4 is installed, the pouring is then carried out... After the precast double-T beam is poured, the side formwork body 201 can be separated from the bottom formwork 101 by activating the hydraulic push rod 203, thus exposing both sides of the double-T beam for quality inspection. After inspection, tensioning can be carried out. During the tensioning process, the disassembly of the side formwork bodies 201 on both sides can avoid the situation where the jacks are affected by the width of the precast beam ribs, thus enabling the production and tensioning of shorter beams without the need to use extended sleeves or additional pads to solve the tensioning problem, reducing the waste of prestressed steel strands. After the pouring is completed, the side formwork body 201 is separated from the bottom formwork 101 by the hydraulic push rod 203, so that the moving platform 1 can move the bottom formwork 101 and the double T beam to the next process for processing, thereby reducing the investment of formwork, reducing the planned area of ​​the beam yard and the corresponding equipment cost investment.

[0020] like Figure 1-10 As shown, the indicating structure 32 includes a liquid storage shell 3210 fixedly connected to the inner side of the side mold body 201. A pressing plate 3212 is slidably connected inside the liquid storage shell 3210. A connecting rod 3211 is fixedly connected to one side of the pressing plate 3212. The other end of the connecting rod 3211 passes through the liquid storage shell 3210 and the side mold body 201 in sequence and is fixedly connected to a trigger plate 3213 slidably connected to the inner wall of the mounting cavity. A first spring 3214 is sleeved on the surface of the connecting rod 3211. The interior of the liquid storage shell 3210 is filled with liquid... The oil pressure indicator structure 32 also includes a mounting cylinder 3022 fixedly connected to the inner side of the side mold body 201. A connecting pipe 3021 is connected to the top of the mounting cylinder 3022, and the other end of the connecting pipe 3021 is connected to the liquid storage shell 3210. An adjusting rod 3023 is slidably connected to the inner wall of the mounting cylinder 3022. A third spring 3024 is sleeved on the surface of the adjusting rod 3023. The upper end of the adjusting rod 3023 passes through the mounting cylinder 3022 and the side mold body 201 in sequence and is flush with the top surface of the side mold body 201. The surface of body 201 has a through hole corresponding to the adjusting rod 3023 for the adjusting rod 3023 to pass through. Under normal conditions, the adjusting rod 3023 is retracted inside the mounting cylinder 3022, and can be inserted into the through hole when pushed by hydraulic oil. The indicating structure 32 also includes a connecting block 3027 fixedly connected to the surface of the side mold body 201. One end of the connecting block 3027 extends above the adjacent side mold body 201, and a trigger cavity is opened at the bottom of the connecting block 3027. The trigger cavity is connected to the adjacent adjusting rod 3023. The trigger chamber is coaxially arranged with an indicator rod 3028 slidably connected to the inner wall. The surface of the indicator rod 3028 is provided with an indicator line 3029. The upper end of the indicator rod 3028 passes through the connecting block 3027. The adjusting rod 3023 is slidably connected to a top rod 3026. The lower end of the top rod 3026 is fixedly connected to the inner wall of the adjusting rod 3023 with a fourth spring 3025. The upper end of the top rod 3026 passes through the adjusting rod 3023, and the top of the top rod 3026 has two symmetrically distributed wedge surfaces. During the process of connecting the side mold body 201 and the bottom mold 101 under the action of the hydraulic push rod 203, the two ends of the bottom mold 101 can be inserted into the mounting cavities opened on the surface of the side mold body 201 on both sides. During this process, the bottom mold 101 can push the trigger plate 3213 to retract along the inner wall of the mounting cavity and push the connecting rod 3211 to retract into the interior of the liquid storage shell 3210, and drive the extrusion plate 3212 to extrude the hydraulic oil stored in the liquid storage shell 3210. During this process, the first spring 3214 (the first spring 3214 is used to limit the position of the extrusion plate 3212 under normal conditions) can be stretched. The compressed hydraulic oil is injected into the interior of the mounting cylinder 3022 through the connecting pipe 3021. The injected hydraulic oil can push the adjusting rod 3023 to move upward and compress the third spring 3024. During this process, the adjusting rod 3023 can be inserted into the through-hole between the side mold body 201 and the adjusting rod 3023, which can drive the push rod 3026 to be inserted into the interior of the trigger cavity, and through the push rod 3026... The upper push indicator rod 3028 of 26 extends from the inside of the connecting block 3027, making the indicator line 3029 flush with the top surface of the connecting block 3027. This indicates that the two adjacent side mold bodies 201 and the bottom mold 101 are installed in place, and the sides of the two adjacent side mold bodies 201 near the bottom mold 101 are on the same plane. When the sides of the two adjacent side mold bodies 201 near the bottom mold 101 are misaligned, the trigger cavity and the through hole in the connecting block 3027 are misaligned, allowing the inner wall of the trigger cavity to press against the top. The wedge-shaped surface of rod 3026 causes it to retract into the interior of adjusting rod 3023. At the same time, the retraction of top rod 3026 reduces the length of indicator rod 3028 extending from the connecting block 3027, thus the indicator line 3029 is blocked by the connecting block 3027. Workers can judge whether the side mold body 201 is aligned by passing through the indicator line 3029 during the process of applying release agent to the surface of side mold body 201 and bottom mold 101, thus avoiding misalignment between side mold bodies 201 that may affect casting.

[0021] like Figure 1-10As shown, the sealing structure 31 includes two sets of adjustment cavities 3103 opened inside the side mold body 201. The two sets of adjustment cavities 3103 are symmetrically distributed with the installation cavity as the center. The inner wall of the adjustment cavity 3103 is slidably connected to a pressure plate 3104. A telescopic rod 3106 is fixedly connected to the side of the pressure plate 3104 near the installation cavity. The other end of the telescopic rod 3106 passes through the adjustment cavity 3103. The installation cavity is provided with two symmetrically distributed sealing plates 3101. The surface of the sealing plate 3101 is fixedly connected to the end of the adjacent telescopic rod 3106 away from the pressure plate 3104. A second spring 3105 is fixedly connected between the surface of the pressure plate 3104 and the inner wall of the adjustment cavity 3103. The side mold body 201 is provided with uniformly distributed conduits 3102. One end of the conduit 3102 is connected to the interior of the adjacent adjustment cavity 3103. The other end of the conduit 3102 passes through the side mold body 201 and is connected to the liquid storage shell 3210. During the process of connecting the side mold body 201 with the bottom mold 101 under the action of the hydraulic push rod 203, the hydraulic oil inside the reservoir 3210 is squeezed by the extrusion plate 3212 and introduced into the interior of the installation cylinder 3022 through the connecting pipe 3021. The other part is injected into the interior of the adjustment cavity 3103 connected to it through the conduit 3102. The hydraulic oil injected into the adjustment cavity 3103 can squeeze the pressure plate 3104 to slide along the inner wall of the adjustment cavity 3103 and drive the telescopic rod 3106 to make the sealing plate 3101 and the surface of the bottom mold 101 fit tightly. During this process, the second spring 3105 can be squeezed to contract. The tight fit between the sealing plate 3101 and the surface of the bottom mold 101 can prevent concrete from entering the interior of the installation cavity through the gap between the bottom mold 101 and the installation cavity during the pouring process, which would make it difficult to separate the side mold body 201 later. After the pouring is completed, the side mold body 201 is separated from the bottom mold 101 by the hydraulic push rod 203. At this time, the pressure on the trigger plate 3213 is released, and the pressing plate 3212 is reset under the action of the first spring 3214. Then, under the action of the second spring 3105 and the third spring 3024, the telescopic rod 3106 and the adjusting rod 3023 are reset respectively, and the hydraulic oil located in the adjusting cavity 3103 and the mounting cylinder 3022 is squeezed back into the storage shell 3210 for storage and reuse.

[0022] like Figure 1-10As shown, the fixing structure 4 includes a screw 401 disposed above the bottom mold 101. The two ends of the screw 401 pass through two adjacent mounting brackets 205 respectively. The surface of the screw 401 is threadedly connected to a threaded sleeve 402. The opposite sides of the two threaded sleeves 402 are fixedly connected to a connecting ring 403 that is slidably connected to the surface of the screw 401. The surface of the connecting ring 403 is provided with annularly distributed limiting grooves 404. The surface of the mounting bracket 205 is provided with a connecting groove that matches the connecting ring 403. The inner wall of the mounting bracket 205 is slidably connected to a limiting block 405. The lower end of the limiting block 405 extends into the interior of the connecting groove. A wedge surface is provided on one side of the limiting block 405. The top of the limiting block 405 is fixedly connected to two mounting rods 407. The upper end of the mounting rod 407 passes through the mounting bracket 205 and is fixedly connected to a pull plate 406. A fifth spring 408 is sleeved on the surface of the mounting rod 407. After the side mold bodies 201 on both sides are installed, the screw 401 is passed through two mounting brackets 205 symmetrically distributed with respect to the bottom mold 101, and then the two threaded sleeves 402 are tightened from both sides of the screw 401. This causes the threaded sleeves 402 to drive the connecting ring 403 to insert into the connecting groove on the adjacent mounting bracket 205. During this process, the connecting ring 403 can rotate with the threaded sleeve 402, thereby continuously changing the position of the limiting groove 404. As the connecting ring 403 is inserted into the connecting groove, it can press the wedge surface of the limiting block 405 through the inner wall of the limiting groove 404. This allows the threaded sleeve 402 to retract into the mounting bracket 205, thus not affecting its normal rotation. The threaded sleeve 402 remains in contact with the surface of the mounting bracket 205, thereby limiting the screw 401. This, in turn, strengthens the limiting effect on the side mold bodies 201 on both sides through the cooperation of the screw 401 and the threaded sleeve 402, reducing mold bulging and improving casting quality. At the same time, the limiting block 405 can be inserted into the limiting groove 404 to prevent the connecting ring 403 from reversing, thus preventing the threaded sleeve 402 from reversing and loosening due to vibration generated during the vibration process after casting.

[0023] In use, before pouring, the bottom mold 101 is moved between the two side mold structures 2 by the moving platform 1. The side mold body 201 is moved closer to the bottom mold 101 by activating the hydraulic push rod 203, so that the two ends of the bottom mold 101 are inserted into the mounting cavities on the two side mold bodies 201 respectively, thus completing the installation between the side mold structure 2 and the bottom mold 101. During this process, the trigger plate 3213 can be pushed to retract along the inner wall of the mounting cavity, and the connecting rod 3211 can be pushed to retract into the interior of the liquid storage shell 3210. Under the action of the indicator structure 32, the upper end of the push rod 3026 can push the indicator rod 3028 to extend out from the interior of the connecting block 3027, so that the indicator line 3029 is flush with the top surface of the connecting block 3027, which indicates that the two adjacent side mold bodies 201 and the bottom mold 101 are installed in place, and the side of the two adjacent side mold bodies 201 closest to the bottom mold 101 is on the same plane. When two adjacent side mold bodies 201 are misaligned on the side closest to the bottom mold 101, the trigger cavity and through hole in the connecting block 3027 are misaligned. This causes the inner wall of the trigger cavity to press the wedge surface of the push rod 3026, causing it to retract into the adjusting rod 3023. Simultaneously, the retraction of the push rod 3026 reduces the length of the indicator rod 3028 extending from the connecting block 3027, thus obscuring the indicator line 3029. Workers can determine whether the side mold bodies 201 are aligned by observing the indicator line 3029 during the application of release agent to the surfaces of the side mold bodies 201 and the bottom mold 101, preventing misalignment between the side mold bodies 201 from affecting the pouring process. Furthermore, the sealing structure 31 enhances the sealing effect between the installation cavity and the bottom mold 101. The fixed structure 4, together with the mounting frame 205, fixes the position of the side formwork bodies 201 on both sides, reducing the bulging of the formwork and improving the casting quality. After the fixed structure 4 is installed, the casting work is carried out. After the precast double T beam is cast, the side formwork bodies 201 can be separated from the bottom formwork 101 by starting the hydraulic push rod 203, so that the two sides of the double T beam can be exposed for quality inspection. After inspection, tensioning is carried out. During the tensioning process, due to the disassembly of the side formwork bodies 201 on both sides, the normal operation of the jacks can be avoided due to the width of the precast beam ribs. Thus, the fabrication and tensioning of shorter beams can be carried out without the need to use extended sleeves or additional pads to solve the tensioning problem, reducing the waste of prestressed steel strands. After the pouring is completed, the side formwork body 201 is separated from the bottom formwork 101 by the hydraulic push rod 203, so that the moving platform 1 can move the bottom formwork 101 and the double T beam to the next process for processing, thereby reducing the investment of formwork, reducing the planned area of ​​the beam yard and the corresponding equipment cost investment.

[0024] It should be noted that the moving stage 1 and hydraulic push rod 203 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the moving stage 1 and hydraulic push rod 203 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
