Abstract
Description
Technical Field
[0001] This application relates to the field of building engineering technology, specifically a device for controlling the thickness of concrete pouring in building engineering. Background Technology
[0002] In the production of precast concrete components, casting using molds is currently the mainstream manufacturing process. In existing technologies, precast molds typically employ a fixed structural design, with the mold cavity width remaining constant after mold fabrication. For example, traditional precast wall panel molds and floor slab molds have fixed spacing between their side panels, requiring molds to be custom-made in advance based on the thickness of the target component.
[0003] However, in practical applications, when it is necessary to produce precast concrete components of different thicknesses (such as wall panel thicknesses to meet different architectural design requirements), this fixed-width mold cannot flexibly change the component thickness by adjusting the mold width. The entire mold must be redesigned, processed, or replaced. This process not only significantly increases the cost of mold customization but also extends the production cycle due to mold replacement operations, reducing the versatility and efficiency of the production line.
[0004] Therefore, this application provides a device for controlling the thickness of concrete pouring in building engineering to solve the above-mentioned problems. Utility Model Content
[0005] This application provides a concrete pouring thickness control device for building engineering, which aims to solve the problems mentioned in the background art, such as the fixed and unadjustable width of existing precast concrete molds, which makes them unable to adapt to the production of components of different thicknesses, the need for frequent mold replacements leading to high costs and low production efficiency, poor mold versatility and high storage costs.
[0006] To achieve the above objectives, this application provides the following technical solution: a device for controlling the thickness of concrete pouring in building engineering, comprising a mold body and a mold cavity disposed on the mold body;
[0007] To facilitate adjustment of the width inside the mold cavity, an adjustment mechanism is provided inside the mold cavity. This mechanism includes an adjustment plate movably disposed inside the mold cavity and two hinge plates symmetrically hinged at both ends of the adjustment plate. A hinge seat is hinged to the end of each hinge plate away from the adjustment plate. A synchronization plate is fixedly connected between the two hinge seats on the same side. A double-headed hydraulic cylinder is fixedly installed in the middle of the inner wall of the mold cavity, and the output shaft of the double-headed hydraulic cylinder is fixedly connected to the synchronization plate. This adjustment mechanism enables stepless adjustment of the width inside the mold cavity, thus meeting the casting requirements of precast concrete components of different thicknesses. It avoids the drawbacks of frequent replacement of traditional fixed molds, significantly improving the versatility and practicality of the device. Simultaneously, the structure design of using a double-headed hydraulic cylinder to drive the synchronization plate ensures uniform and synchronous adjustment force on both sides, preventing the adjustment plate from tilting due to uneven force, and guaranteeing the stability and accuracy of the adjustment process.
[0008] Preferably, to ensure the stability of the adjusting plate's movement: both ends of the mold body are provided with L-plates fixedly connected to the adjusting plate. Two first guide rods, fixedly connected to the mold body, are slidably inserted into the L-plates via circular holes. The cooperation between the L-plates and the first guide rods provides high-precision guiding constraints for the horizontal movement of the adjusting plate, effectively preventing vertical swaying or tilting during movement, ensuring stable sliding in a vertical state, thereby improving the accuracy and reliability of the mold cavity width adjustment, avoiding uneven component thickness caused by adjusting plate offset, and further enhancing the stability of the device.
[0009] Preferably, to improve the strength of the adjusting plate: a plurality of grid plates composed of horizontal and vertical plates are fixedly connected to one end of the adjusting plate facing the hinge plate. The grid plates significantly enhance the structural strength and deformation resistance of the adjusting plate, enabling it to maintain a flat surface when subjected to lateral pressure during concrete pouring or mechanical stress during the adjustment process, avoiding dents or bending caused by excessive local stress, thereby extending the service life of the adjusting plate, while ensuring the sealing of the mold cavity wall and the forming accuracy of the component.
[0010] Preferably, to ensure the stability of the hinge plate position adjustment: second guide rods are fixedly connected to both the upper and lower sides of the inner wall of the mold cavity corresponding to the double-headed hydraulic cylinder, and the hinge seat is slidably sleeved on the second guide rods. The second guide rods provide precise track constraints for the movement of the hinge seat, ensuring that the hinge plate always swings along a preset direction during the adjustment process, avoiding disordered movement trajectory of the hinge plate caused by hinge seat offset, thereby ensuring the synchronization and stability of the adjustment mechanism, reducing mechanical wear, and improving the long-term reliability of the device.
[0011] Preferably, to improve the strength of the hinge plate: a support plate is hinged to the inner end of the second guide rod, and the end of the support plate away from the second guide rod is hinged to the middle of the hinge plate. The support plate, the hinge plate, and the second guide rod form a triangular support structure. Utilizing the stability principle of a triangle, this significantly enhances the bending resistance and load-bearing capacity of the hinge plate, making it less prone to deformation when transmitting adjustment forces. This improves the overall rigidity of the adjustment mechanism, reduces structural deformation caused by the component's own weight or the lateral pressure of concrete, and ensures adjustment accuracy and long-term stability.
[0012] Preferably, the length of the support plate is half that of the hinge plate. The length of the support plate is designed so that its hinge point is located exactly at the midpoint of the hinge plate, which can provide symmetrical and balanced support to the hinge plate, avoid uneven force due to the offset of the support point, and thus further improve the stability and uniformity of the hinge plate, ensure consistent power transmission on both sides of the adjustment mechanism, and prevent the adjustment plate from tilting due to the difference in support strength on one side.
[0013] This application, through the setting of the adjustment mechanism, can achieve stepless adjustment of the width inside the mold cavity, thereby meeting the casting requirements of precast concrete components of different thicknesses, avoiding the drawbacks of frequent replacement of traditional fixed molds, and significantly improving the versatility and practicality of the device; at the same time, the structural design of the synchronous plate driven by the double-headed hydraulic cylinder can ensure that the adjustment force on both sides is uniform and synchronous, avoiding the tilting of the adjustment plate due to uneven force, and ensuring the stability and accuracy of the adjustment process.
[0014] This application forms a triangular support structure by using a support plate, a hinge plate, and a second guide rod. By utilizing the stability principle of triangles, the bending resistance and load-bearing capacity of the hinge plate are significantly enhanced, making it less prone to deformation when transmitting adjustment forces. This improves the overall rigidity of the adjustment mechanism, reduces structural deformation caused by the self-weight of the components or the lateral pressure of the concrete, and ensures adjustment accuracy and long-term stability.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0022] Example 1
[0023] This embodiment provides a device for controlling the thickness of concrete pouring in building engineering, such as... Figure 1-4 As shown, the thickness control device includes a mold body 1 and a mold cavity 2 disposed on the mold body 1. In order to facilitate the adjustment of the width inside the mold cavity 2, an adjustment mechanism 3 is provided inside the mold cavity 2. The adjustment mechanism 3 includes an adjustment plate 31 movably disposed inside the mold cavity 2 and two hinge plates 32 symmetrically hinged at both ends of the adjustment plate 31. A hinge seat 33 is hinged to the end of the hinge plate 32 away from the adjustment plate 31. A synchronization plate 34 is fixedly connected between the two hinge seats 33 located on the same side. A double-headed hydraulic cylinder 35 is fixedly installed in the middle of the inner wall of the mold cavity 2, and the output shaft of the double-headed hydraulic cylinder 35 is fixedly connected to the synchronization plate 34. By adjusting the mechanism 3, the width of the mold cavity 2 can be infinitely adjusted, thus meeting the casting requirements of precast concrete components of different thicknesses. This avoids the drawbacks of frequent replacement of traditional fixed molds and significantly improves the versatility and practicality of the device. Simultaneously, the structure design of using a double-headed hydraulic cylinder 35 to drive the synchronous plate 34 ensures uniform and synchronous adjustment forces on both sides, preventing the adjusting plate 31 from tilting due to uneven force, and guaranteeing the stability and accuracy of the adjustment process. When the output shaft of the double-headed hydraulic cylinder 35 extends, it drives the synchronous plates 34 on both sides to move in opposite directions. The synchronous plate 34 pulls one end of the hinge plate 32 towards the center through the hinge seat 33, while the other end of the hinge plate 32 pushes the adjusting plate 31 to translate away from the double-headed hydraulic cylinder 35, thereby reducing the internal width of the mold cavity 2. Conversely, when the output shaft of the double-headed hydraulic cylinder 35 retracts, the synchronous plate 34 moves in the opposite direction, one end of the hinge plate 32 unfolds outward, pushing the adjusting plate 31 towards the double-headed hydraulic cylinder 35, thereby expanding the internal width of the mold cavity 2. The outer wall of the adjusting plate 31 is always in contact with the inner wall of the mold cavity 2. By moving it horizontally, the usable width of the mold cavity 2 can be directly changed, thereby adjusting the thickness of the precast concrete component.
[0024] To ensure the stability of the adjustment plate 31's movement, L-plates 36 are fixedly connected to the adjustment plate 31 at both ends of the mold body 1. Two first guide rods 37, fixedly connected to the mold body 1, are slidably inserted into the L-plates 36 via round holes. The cooperation between the L-plates 36 and the first guide rods 37 provides high-precision guiding constraints for the horizontal movement of the adjustment plate 31, effectively preventing vertical swaying or tilting during movement and ensuring stable sliding in a vertical position. This improves the accuracy and reliability of the mold cavity 2 width adjustment, avoids uneven component thickness caused by the adjustment plate 31's offset, and further enhances the stability of the device. The L-plates 36 at both ends of the adjustment plate 31 are fitted onto the two first guide rods 37 via round holes. The first guide rods 37 are fixedly connected to the mold body 1, forming a fixed horizontal guide track. When the adjusting plate 31 is pushed or pulled by the hinge plate 32, the L plate 36 slides along the axial direction of the first guide rod 37. Since the first guide rod 37 restricts the L plate 36's degree of freedom in the vertical direction (such as the up and down direction), it only allows it to move horizontally, thereby forcing the adjusting plate 31 to always maintain a vertical posture, avoiding deflection due to force eccentricity, and ensuring the consistency of width adjustment on both sides of the mold cavity 2.
[0025] To enhance the strength of the adjusting plate 31, a plurality of grid plates 311, composed of horizontal and vertical plates, are fixedly connected to the end of the adjusting plate 31 facing the hinge plate 32. The grid plates 311 significantly enhance the structural strength and deformation resistance of the adjusting plate 31, enabling it to maintain a flat surface when subjected to lateral pressure during concrete pouring or mechanical stress during adjustment. This prevents dents or bending caused by excessive local stress, thereby extending the service life of the adjusting plate 31 and ensuring the sealing of the inner wall of the mold cavity 2 and the forming accuracy of the component. The grid plates 311 are formed by cross-welding or integrally molding horizontal and vertical plates to create a grid-like support structure, covering the side of the adjusting plate 31 facing the hinge plate 32 (i.e., the non-concrete contact surface). When the adjusting plate 31 is subjected to the lateral pressure of concrete or the thrust of the hinged plate 32, the horizontal and vertical plates of the grid plate 311 disperse the local concentrated force to the entire plate surface. Through the stress dispersion principle in structural mechanics, the single-point force is transformed into the overall force of the grid, which effectively improves the compressive stiffness and bending strength of the adjusting plate 31, so that it can maintain a stable geometric shape under high load.
[0026] To ensure the stability of the hinge plate 32 position adjustment: Second guide rods 38 are fixedly connected to both the upper and lower sides of the inner wall of the mold cavity 2 corresponding to the double-headed hydraulic cylinder 35, and the hinge seat 33 is slidably sleeved on the second guide rods 38. The second guide rods 38 provide precise track constraints for the movement of the hinge seat 33, ensuring that the hinge plate 32 always swings along a preset direction during adjustment, avoiding disordered movement trajectory of the hinge plate 32 due to the offset of the hinge seat 33, thereby ensuring the synchronization and stability of the adjustment mechanism 3, reducing mechanical wear, and improving the long-term reliability of the device. The second guide rods 38 are fixedly installed on the inner wall of the mold cavity 2 and parallel to the axial direction of the double-headed hydraulic cylinder 35. The hinge seat 33 is slidably sleeved on the second guide rods 38, forming a connection structure that can slide along the axial direction of the rod. When the synchronizing plate 34 drives the hinge seat 33 to move, the hinge seat 33 is restricted by the second guide rod 38 and can only slide along the direction of the rod (i.e., the horizontal direction), thereby constraining the lower end of the hinge plate 32 to move only in the horizontal direction, ensuring that the swing angle and thrust direction of the hinge plate 32 are accurately controllable, and avoiding adjustment deviations caused by lateral displacement.
[0027] Example 2
[0028] Unlike Embodiment 1, to improve the strength of the hinge plate 32, a support plate 39 is hinged to the inner end of the second guide rod 38, and the end of the support plate 39 away from the second guide rod 38 is hinged to the middle of the hinge plate 32. The support plate 39, the hinge plate 32, and the second guide rod 38 form a triangular support structure. Utilizing the stability principle of a triangle, this significantly enhances the bending resistance and load-bearing capacity of the hinge plate 32, making it less prone to deformation when transmitting adjustment forces. This improves the overall rigidity of the adjustment mechanism 3, reduces structural deformation caused by the component's own weight or the lateral pressure of concrete, and ensures adjustment accuracy and long-term stability. One end of the support plate 39 is hinged to the inner end of the second guide rod 38, and the other end is hinged to the middle of the hinge plate 32 (near the middle of the hinge plate 32), forming a triangular support structure with the second guide rod 38 as the base and the support plate 39 and the hinge plate 32 as the two sides. When the hinge plate 32 is subjected to an adjustment force (push or pull), the support plate 39 decomposes the force into pressure or tension along the axis of the support plate 39 through the hinge point. By utilizing the rigidity of the triangle, the force on the middle part of the hinge plate 32 is transformed into the overall force of the triangular structure, which effectively suppresses the bending deformation of the middle part of the hinge plate 32, ensures that it transmits power at a stable angle, and avoids structural failure caused by single-point force.
[0029] The length of the support plate 39 is half that of the hinge plate 32. The design of the support plate 39's length (half the length of the hinge plate 32) ensures that its hinge point is located precisely at the midpoint of the hinge plate 32. This provides symmetrical and balanced support to the hinge plate 32, preventing uneven force distribution due to support point misalignment. This further enhances the stability and uniformity of force distribution on the hinge plate 32, ensuring consistent power transmission on both sides of the adjustment mechanism 3 and preventing tilting of the adjustment plate 31 due to differences in support strength on one side. Since the support plate 39 is hinged at the midpoint of the hinge plate 32, when the hinge plate 32 swings, the hinge points at both ends of the support plate 39 form symmetrical lever arms. This allows the forces on the upper and lower parts of the hinge plate 32 to be evenly transmitted to the second guide rod 38 through the support plate 39, preventing torque imbalance caused by the support point being too high or too low. For example, when the end of the hinge plate 32 away from the adjusting plate 31 is pulled by the synchronous plate 34, the support plate 39 at the midpoint can evenly distribute the pulling force to the upper and lower sections of the hinge plate 32, so that the hinge plate 32 as a whole swings stably with the midpoint as the fulcrum, ensuring that the thrust on both sides is symmetrical during the adjustment process and maintaining the horizontal movement accuracy of the adjusting plate 31.
[0030] The control method of this application is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
[0031] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.
[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
