Abstract
Description
Technical Field
[0001] This invention belongs to the field of concrete pouring technology, and specifically relates to a prefabricated building concrete pouring device. Background Technology
[0002] In the field of prefabricated buildings, the application of precast concrete slabs with steel trusses as stiffeners, combined with cast-in-place concrete to form integral components (such as floor slabs and roof slabs), is becoming increasingly widespread. However, traditional concrete pouring equipment is difficult to adapt to the construction requirements of such components. On the one hand, traditional equipment often separates pouring and vibration, making it impossible to accurately grasp the timing of coordinated pouring and vibration of precast slabs and cast-in-place layers. When faced with unidirectional arrangement of precast steel reinforcement, it cannot fully utilize the advantages of unidirectional steel reinforcement to achieve smooth operation and efficient vibration of the vibrator, resulting in problems such as loose bonding and insufficient compaction at the joints between concrete layers, affecting the overall quality of the component.
[0003] On the other hand, traditional equipment has a low degree of automation. During the layered pouring process, a large amount of manual operation is required to adjust parameters such as the height of the vibrator and control the pouring thickness and speed. This is not only inefficient and labor-intensive, but also prone to human error, making it difficult to ensure uniform pouring thickness and consistent vibration depth for each layer. This fails to meet the high-precision and high-quality construction requirements of such precast-cast-in-place composite components.
[0004] Chinese Patent Publication No. CN220994885U discloses a prefabricated building concrete pouring device, including a support frame. The support frame contains an adjustment component and a guide component, which are connected to the same pouring component. The pouring component contains two mixing components, each connected to two drive components via a transmission component. Both drive components are connected to the support frame. This patent controls the operation of the adjustment component, which drives the pouring component to move between the two drive components. Simultaneously, both drive components drive the two mixing components via transmission components to mix the concrete within the pouring component. This device only requires controlling the adjustment component to move the pouring component and mix the concrete inside, simplifying operation and reducing the cost of using the pouring device.
[0005] However, in actual use, the above-mentioned device lacks the function of autonomously vibrating concrete in layers, resulting in gaps between concrete layers and poor interlayer bonding. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This invention forms a cyclical working mode of "pouring-vibration-re-pouring-re-vibration" through the cooperation of various components. By utilizing the linkage between the pouring component and the elastic component, the height of the vibration component is automatically adjusted according to the weight change, so that it is always located below the joint between concrete layers. This seamlessly connects the pouring and vibration processes of each layer, focusing on fully vibrating the joint between layers, effectively eliminating gaps between layers, enhancing interlayer adhesion, and making the concrete structure a whole. This avoids the time wasted due to manual intervention, making the construction process more compact and efficient, and significantly shortening the overall construction cycle.
[0018] 2. This invention utilizes the coordination between the casting component, elastic component, vibrating component, leveling component, and lever component, as well as the different weight changes of the concrete box during the three-layer casting process, to drive the vibrator to move autonomously in stages. It focuses on fully vibrating the interlayer bonding areas, effectively eliminating interlayer gaps, enhancing interlayer adhesion, and allowing the concrete structure to form a whole, thereby improving structural stability. Furthermore, it combines the removal of the vibrator with the surface treatment of the concrete into one process, avoiding waiting and connection time between construction steps and effectively improving construction efficiency.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0031] Example 1, as Figure 1 and Figure 7As shown, the movable seat 2, the casting component 3, the elastic component 4, the vibrating component 5, the leveling component 6, and the lever component 7 are provided. The movable seat 2 is provided on the upper side of the prefabricated building formwork 1. The sliding grooves 21 are provided on both sides of the rear end of the movable seat 2. The casting component 3 is provided on the upper side of the movable seat 2. The elastic components 4 are provided on both the left and right sides of the casting component 3. The vibrating component 5 is provided on the front side of the casting component 3. The leveling component 6 is provided on the rear side of the casting component 3. The lever component 7 is provided on the lower side of the movable seat 2.
[0032] Therefore, this solution forms a cyclical working mode of "pouring-vibration-re-pouring-re-vibration" through the cooperation of various components. By utilizing the linkage between the pouring component 3 and the elastic component 4, the height of the vibration component 5 is automatically adjusted according to the weight change, so that it is always located under the concrete interlayer connection. This seamlessly connects the pouring and vibration processes of each layer, focusing on fully vibrating the interlayer bonding area, effectively eliminating interlayer gaps, enhancing interlayer adhesion, and making the concrete structure a whole. This avoids the time wasted due to manual intervention, making the construction process more compact and efficient, and significantly shortening the overall construction cycle.
[0033] Example 2 is based on Example 1, and aims to achieve the effect of automatic layered vibration compaction.
[0034] See Figures 2-4 The casting assembly 3 includes a fixed outer shell 31 fixedly connected to the upper end of the movable base 2. Several springs 32 are fixedly connected to the upper end of the movable base 2. A support plate 33 is fixedly connected to the upper end of the several springs 32. Arc-shaped protrusions 331 are fixedly connected to both the left and right sides of the support plate 33. A concrete box 34 is fixedly connected to the upper end of the support plate 33. Seven telescopic pipes 35 are fixedly connected to the lower end of the concrete box 34. Seven discharge ports 36 are provided at the lower end of the movable base 2. The lower ends of the seven telescopic pipes 35 are all fixedly connected to the discharge ports 36 at the appropriate positions.
[0035] The concrete box 34 described above is equipped with multiple sets of stirring rods to prevent the concrete from solidifying in the concrete box 34. In addition, a delivery pump is installed at the connection between the bottom of the concrete box 34 and the telescopic pipe 35 to deliver the concrete. All of the above designs are in the conventional technical field of the prior art, so they will not be described in detail in this case.
[0036] Furthermore, the telescopic tube 35 is telescopic and can expand and compress as the concrete box 34 rises;
[0037] Spring 32 is made of 60Si2Mn silicon manganese steel, which has high tensile strength and high resilience. The specific dimensions can be designed according to actual production needs.
[0038] See Figures 2-6The elastic component 4 includes a partition plate 41 fixedly connected to the left side of the inner surface of the fixed housing 31, a plurality of springs 42 fixedly connected to the left side of the upper end of the movable seat 2, a movable plate 43 fixedly connected to the upper ends of the plurality of springs 42, the outer surface of the movable plate 43 being slidably connected to the left end of the partition plate 41, a limit post 44 fixedly connected to the upper end of the movable plate 43, two limit mechanisms 45 being provided on the left side of the inner surface of the fixed housing 31, two through slots adapted to the limit mechanisms 45 being opened on the outer surface of the partition plate 41, a connecting frame 46 fixedly connected to the front side of the upper end of the movable plate 43, two support columns 47 fixedly connected to the upper end of the movable plate 43, a support seat 48 fixedly connected to the left side of the upper end of the concrete box 34, a pressure block 49 fixedly connected to the left end of the support seat 48, and the lower end of the pressure block 49 contacting the upper end of the support column 47.
[0039] Furthermore, the material of spring 242 is 60Si2Mn silicon manganese steel, which has high tensile strength and high resilience. The specific dimensions can be designed according to actual production needs.
[0040] The upper end of the limiting post 44 is provided with a ball bearing, which can reduce the friction between the limiting post 44 and the sliding block 452, so that the limiting post 44 can smoothly enter the through hole 455 during the movement of the sliding block 452.
[0041] Furthermore, the support base 48 and the pressure block 49 mentioned above can descend with the weight of the concrete box 34, thereby squeezing the support column 47 and the movable plate 43 to descend, so that they return to their initial positions together with the concrete box 34.
[0042] The limiting mechanism 45 includes a fixing block 451 fixedly connected to the left side wall of the inner surface of the fixed housing 31, a sliding block 452 slidably connected to the outer surface of the fixing block 451, a spring 453 fixedly connected to the right end of the fixing block 451, a fixing block 454 fixedly connected to the right end of the spring 453, the outer surface of the fixing block 454 fixedly connected to the inner surface of the sliding block 452, a through hole 455 opened on the outer surface of the sliding block 452, the outer surface of the limiting post 44 slidably connected to the through hole 455, the outer surface of the sliding block 452 slidably connected to the through groove, and the outer surface of the left arc-shaped protrusion 331 slidably connected to the sliding block 452.
[0043] Furthermore, the travel distance of the arc-shaped protrusion 331 to the lower end of the telescopic tube 35 is equal to the travel distance at the end of the first layer of concrete pouring for the prefabricated building formwork 1. Then, the arc-shaped protrusion 331 continues to move upward from the above position to the lower end of the upper telescopic tube 35, and the travel distance is equal to the travel distance for the second layer of pouring. Finally, the travel distance of the arc-shaped protrusion 331 to the upper end of the upper telescopic tube 35 is equal to the travel distance for the third layer of pouring. The state of the third layer of pouring is referenced. Figure 3 .
[0044] See Figure 6 and Figure 7 The vibrating assembly 5 includes a lifting seat 51 fixedly connected to the lower end of the connecting frame 46. Two vertically arranged limiting rods 52 are fixedly connected to the middle position of the lifting seat 51. Seven sliding seats 53 are slidably connected to the outer surfaces of the two limiting rods 52. The front ends of the seven sliding seats 53 are rotatably connected to a rotating shaft 54. The rotating shaft 54 located in the middle position extends to the rear end of the sliding seat 53 that is adapted to it and is rotatably connected to the lifting seat 51.
[0045] The outer surfaces of the seven rotating shafts 54 are rotatably connected to the telescopic frame 541. The inner surfaces of the seven sliding seats 53 are slidably connected to the sliding blocks 55. The inner surfaces of the seven sliding blocks 55 are equipped with vibrating rods 56. The left side of the lifting seat 51 is fixedly installed with a hydraulic device 57. The output end of the hydraulic device 57 is fixedly connected to a connecting seat 58. The lower end of the connecting seat 58 is fixedly connected to the right sliding seat 53.
[0046] Furthermore, activating the hydraulic device 57 can move the rightmost sliding seat 53. When it moves to the left, it will move the seven sliding seats 53, the telescopic frame 541, the sliding block 55, and the vibrating rod 56 together towards the center, reducing the spacing. When it moves to the right, it will move the seven sliding seats 53, the telescopic frame 541, the sliding block 55, and the vibrating rod 56 together outward, increasing the spacing, thereby vibrating the lateral position of the prefabricated building formwork 1.
[0047] Among them, the middle sliding seat 53 and the rotating shaft 54 remain stationary, while only the three sliding seats 53 on both sides move.
[0048] Furthermore, the reference state of concrete box 34 filled with concrete. Figure 2 Spring 32 and spring 42 are both in a compressed state. The entire moving device moves to the top of the prefabricated building formwork 1 and starts the seven conveying pumps inside the concrete box 34 to deliver concrete to the prefabricated building formwork 1 for moving and pouring.
[0049] Precast wall panels need to be poured in layers. When pouring the precast building formwork 1, as the amount of concrete inside the concrete box 34 decreases, the pressure on the spring 32 gradually decreases, which in turn causes the concrete box 34 to slowly rise. During the process, when the arc-shaped protrusion 331 moves to the lower end of the limiting mechanism 45, the concrete box 34 has just finished pouring the first layer of concrete. Then, according to the appropriate time, the vibrator 56 can be started and the device can be pushed to move in the opposite direction to vibrate the first layer of concrete.
[0050] It should be noted that when the concrete box 34 is filled with concrete, the lifting seat 51 and the vibrator 56 are located at the bottom. The vibrator 56 is located inside the lower part of the first layer of concrete but does not contact the bottom of the prefabricated building formwork 1. Therefore, in this state, the vibrator 56 can fully vibrate the first layer of poured concrete.
[0051] When pouring the second layer of the prefabricated building formwork 1, the vibrator 56 stops operating, the moving device continues, and the conveying pump is started to deliver concrete. As the concrete inside the concrete box 34 continues to decrease, the arc-shaped protrusion 331 will continue to rise slowly. During this process, it will squeeze the lower sliding block 452. Since the contact surfaces of the sliding block 452 and the arc-shaped protrusion 331 are both arc surfaces, the arc-shaped protrusion 331 will push the sliding block 452 to retract, thereby moving the through hole 455 to the position of the limiting post 44. After the limiting post 44 and the movable plate 43 lose resistance, they will be driven upward by the elasticity of the spring 42, passing through the through hole 455, to... The lower end of the upper sliding block 452 abuts against the ground, thereby driving the connecting frame 46 and the lifting seat 51 to move upward as a whole, so that the vibrator 56 leaves its original vibration position and is located slightly below the junction of the first layer of concrete and the second layer of concrete. After the second layer of concrete is poured, the arc-shaped protrusion 331 has moved to the lower end of the upper telescopic tube 35. At this time, the vibrator 56 is started and the device is moved to fully integrate and vibrate the newly poured concrete with the lower layer of concrete, expel air bubbles, and allow the newly poured concrete to fully penetrate into the pores on the surface of the lower layer of concrete, enhance chemical bonding, effectively eliminate interlayer gaps, and avoid delamination.
[0052] Furthermore, in the same manner as described above, the third layer of the prefabricated building formwork 1 is poured. During the pouring process, the vibrator 56 stops operating, and due to the change in weight of the concrete box 34, the arc-shaped protrusion 331 rises to the upper side of the upper limiting mechanism 45. During this process, the sliding block 452 also moves, allowing the limiting column 44 to pass through the upper through hole 455. At the same time, the movable plate 43 is also stuck at the lower end of the lower sliding block 452, causing the lifting seat 51 and the vibrator 56 to continue to rise a part, so that the vibrator 56 is located slightly below the junction of the second layer of concrete and the uppermost layer of concrete. Then, this part is vibrated. The whole process realizes automatic and rapid adjustment of the vibrator 56 without manual intervention, making the pouring and vibration process more coherent and smooth, greatly improving construction efficiency and shortening the construction cycle.
[0053] Finally, during the next pour, concrete is poured back into the concrete box 34. Due to the change in weight, the concrete box 34 will cause the support base 48 and the pressure block 49 to descend together, thereby pressing down the support columns 47 on both sides and the movable plate 43 to descend together, causing the limiting column 44 to disengage from the through hole 455, thereby causing the two limiting mechanisms 45 to reset, and thus the limiting column 44, the movable plate 43 and the spring 42 also return to their initial positions.
[0054] See Figure 7 The vibration leveling component 6 includes a fixed base 61 fixedly connected to the rear end of the movable base 2. A hydraulic device 62 is fixedly installed on the upper end of the fixed base 61. A rotating sleeve 63 is fixedly connected to the output end of the hydraulic device 62. A rotating rod 64 is rotatably connected to the inner surface of the rotating sleeve 63. Limiting shafts 65 are fixedly connected to both sides of the outer surface of the rotating rod 64. A plate vibrator 66 is fixedly installed at the lower end of the two limiting shafts 65. Rotating columns 67 are rotatably connected to both ends of the rotating rod 64. Several threaded holes are opened in a ring at the ends of the two rotating columns 67 that are far apart from each other. Handles 68 are fixedly connected to both ends of the rotating rod 64. Bolts 69 are rotatably connected to the inner surfaces of the two handles 68.
[0055] Furthermore, the plate vibrator 66 can level the surface of concrete.
[0056] The outer surface of bolt 69 is threaded to the threaded hole. Sliding block 3 610 is fixedly connected to the outer surface of both rotating columns 67. Limiting column 2 611 is fixedly connected to the inner surface of both sliding grooves 21. The outer surface of both limiting column 2 611 is slidably connected to the two sliding blocks 3 610.
[0057] The hydraulic device 62 is activated, causing the rotating sleeve 63 and the plate vibrator 66 to descend. When adjusting the angle of the plate vibrator 66, the handle 68 can be rotated to the appropriate position, and the bolt 69 can be turned to connect with the threaded hole. When the concrete is highly fluid, tilting the plate vibrator 66 forward at a certain angle can better level excess concrete, preventing surface waves or water accumulation. If the concrete is relatively dry and hard, and thick, tilting it backward can enhance the compaction effect of the plate vibrator 66, making the concrete surface denser. By flexibly adjusting the angle, it can adapt to various complex construction scenarios.
[0058] See Figures 8-10The lever assembly 7 includes a second rotating seat 71 that is rotatably connected to both the left and right sides of the movable seat 2. A rotating plate 72 is fixedly connected to the outer surface of each of the two rotating seats 71. A limiting seat 73 is fixedly connected to the lower end of the movable seat 2. A second sliding seat 74 is slidably connected to the inner surface of the limiting seat 73. A ring frame 75 is fixedly connected to the front end of the second sliding seat 74. The outer surfaces of the seven vibrating rods 56 are slidably connected to the ring frame 75. Both the left and right ends of the ring frame 75 are in contact with the upper ends of the two rotating plates 72. Both the left and right ends of the rotating rod 64 are in contact with the upper ends of the two rotating plates 72.
[0059] Furthermore, the ring frame 75 mentioned above is hollowed out and its width is smaller than that of the sliding block 55. This will not affect the left and right movement of the multiple vibrating rods 56, and the sliding block 55 can be pushed into the sliding seat 53 by the rotating plate 72, thereby allowing the vibrating rods 56 to separate from the top layer of concrete.
[0060] Furthermore, when the hydraulic device 62 is activated to lower the plate vibrator 66, the rotating rod 64 will cause the rear end of the rotating plate 72 to press down, thereby causing its front end to tilt up. In turn, the front end of the rotating plate 72 will push the ring frame 75 upward, causing the ring frame 75 to slide the sliding block 55 into the interior of the sliding seat 53. This allows the vibrating rod 56 to separate from the top layer of concrete, combining the removal of the vibrating rod 56 and the surface treatment of the concrete into one process. This avoids waiting and connection time between construction processes and effectively improves construction efficiency.
[0061] Therefore, this solution utilizes the coordination between the pouring component 3, the elastic component 4, the vibrating component 5, the leveling component 6, and the lever component 7, as well as the different weight changes of the concrete box 34 during the three-layer pouring, to drive the vibrating rod 56 to move autonomously in stages. This ensures thorough vibration of the interlayer bonding areas, effectively eliminating interlayer gaps, enhancing interlayer adhesion, and allowing the concrete structure to form a whole, thus improving structural stability. Furthermore, the removal of the vibrating rod 56 and the surface treatment of the concrete are combined into one process, avoiding waiting and connection time between construction steps and effectively improving construction efficiency.
[0062] The working principle is the same as described in the above embodiments, and the specific position of the limiting mechanism 45 in the figure can be adjusted according to actual production needs.
[0063] It should be noted that the specific installation methods, circuit connection methods, and control methods of the delivery pump, movable seat 2, hydraulic device 57 and hydraulic device 62 used in this invention are all conventional designs, and will not be described in detail in this invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
