Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to precast reinforced concrete formwork structures for building frame beams and columns. Background Technology

[0002] Precast concrete columns are concrete columns prefabricated in a prefabrication plant according to the design specifications. They are then poured and shaped using specific molds and finally assembled on site. To ensure the concrete columns have accurate dimensions and surface flatness, formwork is used during the pouring process. Prefabricating components using formwork reduces on-site concrete construction, lowers construction period risks and costs, and improves construction efficiency and quality. Various materials are used for precast concrete column formwork, including wood and steel. Wood formwork is widely used due to its low cost and ease of processing and installation; while steel formwork has advantages such as high strength, good durability, and high reusability, making it particularly suitable for large or high-precision precast components. However, a problem exists in the pouring of precast concrete: the impact force of falling concrete can easily cause deformation at the impact point of the formwork. This deformation leads to unevenness on the concrete surface, affecting not only the building's appearance and aesthetics but also the overall structural stability. Therefore, we propose a precast reinforced concrete formwork structure for building frame beams and columns. Summary of the Invention

During concrete pouring, especially with large volumes or high-drop pours, significant impact forces are generated. Adding extra support effectively disperses and absorbs these impact forces, reducing direct impact on the main structure and protecting it from damage. This locally reinforced support method more effectively disperses and resists impact loads, maintaining the flatness of the formwork. The geometric dimensions and additional supports help distribute the enormous load generated during concrete pouring, reducing the pressure on a single support point and thus lowering the risk of deformation due to excessive localized stress on the formwork. The adjustable component setup also allows for synchronized adjustment of the support plate height according to the height of the concrete within the mold. As the concrete height increases, the load on the mold gradually increases. To maintain mold stability and prevent deformation or overturning due to excessive load, the position of the support rods can be adjusted to better distribute and support the load. Furthermore, as the concrete height increases, the load on the mold also gradually increases. Timely adjustment of the support center ensures that the mold remains balanced and stable during pouring, reducing the risk of deformation or overturning caused by uneven load distribution.

Detailed Implementation

[0029] 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.

[0030] Example 1

[0031] Please see Figures 1-12 The present invention provides a technical solution:

[0032] The precast reinforced concrete formwork structure for building frame beams and columns includes a formwork platform 1, a casting mold 2, a material guide frame 12 and a material guide hopper 13 set on the material guide frame 12, and also includes a support plate 3, which is located on the formwork platform 1 and supports the casting mold 2 when it is impacted by concrete.

[0033] The support mechanism 4 is mounted on the mold table 1, and the support plate 3 is mounted on the support mechanism 4. The support mechanism 4 drives the support plate 3 to move and deflect, thereby supporting the position of the casting mold 2 that is impacted by concrete.

[0034] The advantage of setting up support mechanism 4 is that it can follow the falling position of concrete during pouring and provide additional support to the position of the pouring mold 2 that is impacted by the falling concrete. During the concrete pouring process, especially when pouring large volume concrete or high drop concrete, a large impact force will be generated. Adding additional support can effectively disperse and absorb these impact forces, reduce the direct impact on the main structure, and thus protect the main structure from damage. This locally reinforced support method can more effectively disperse and resist impact loads, maintain the flatness and geometric dimensions of the formwork, and the additional support can help disperse the huge load generated during concrete pouring, reduce the pressure borne by a single support point, and thus reduce the risk of deformation of the pouring mold 2 due to excessive local stress.

[0035] Adjustment component 9 is installed on support mechanism 4. Adjustment component 9 is used to adjust the support height of support plate 3 synchronously according to the height of concrete pouring in casting mold 2.

[0036] The advantage of setting the adjustment component 9 is that it can synchronously adjust the support height of the support plate 3 according to the height of the concrete in the casting mold 2. As the concrete height increases, the load borne by the casting mold 2 gradually increases. In order to maintain the stability of the casting mold 2 and prevent it from deforming or overturning due to excessive load, the position of the support plate 3 can be adjusted to better distribute and support the load. Moreover, as the concrete height increases, the load borne by the casting mold 2 also gradually increases. Timely adjustment of the support center can ensure that the casting mold 2 remains balanced and stable during the casting process, reducing the risk of deformation or overturning caused by uneven load. At the same time, by adjusting the position of the support plate 3 to maintain the stability of the casting mold 2, the safety risks during construction can be reduced, and safety accidents caused by the instability of the casting mold 2 can be prevented.

[0037] The support mechanism 4 includes a movable component 5 mounted on the mold table 1, which drives the support plate 3 to move. The movable component 5 is provided with an mounting component 6, which fixes the support plate 3 in place. The mounting component 6 is provided with an unfolding component 7, which controls the unfolding and retraction of the support plate 3. The unfolding component 7 is provided with a driving component 8, which provides power for the unfolding component 7 to work.

[0038] The movable component 5 includes a mounting rod 51 mounted on the mold table 1. The mounting rod 51 has a mounting groove 52. A sliding block 53 is slidably mounted in the mounting groove 52. The sliding block 53 is connected to the guide frame 12. A drive screw 54 is rotatably mounted in the mounting groove 52. The drive screw 54 passes through the sliding block 53 and is threadedly connected to the sliding block 53. A drive motor 55 is mounted in the mounting groove 52. The power output end of the drive motor 55 is connected to the drive screw 54. A moving groove 56 is mounted in the mold table 1. The moving groove 56 communicates with the mounting groove 52. An extension rod 57 is slidably mounted in the moving groove 56. One end of the extension rod 57 is connected to the sliding block 53.

[0039] The advantage of the movable part 5 is that the position of the support plate 3 can be adjusted synchronously according to the position of the concrete falling in the casting mold 2, so that the support plate 3 can always support and fix the position of the casting mold 2 under impact.

[0040] The mounting component 6 includes through slots 61 formed on the mold base 1 on both sides of the casting mold 2. The through slots 61 are connected to the moving slot 56. Multiple positioning plates 62 are provided on the extension rod 57. The positioning plates 62 are slidably connected to the through slots 61. The multiple positioning plates 62 are respectively located on both sides of the casting mold 2. The positioning plates 62 are provided with sliding slots 63. The mounting blocks 64 are slidably arranged in the sliding slots 63. The mounting blocks 64 are provided with rotating seats 65. The rotating seats 65 are rotatably arranged with connecting rods 66. The connecting rods 66 are rotatably connected to the support plate 3. The support plate 3 is provided with multiple limiting slots 67. Multiple extrusion rods 68 are slidably arranged in the limiting slots 67.

[0041] The unfolding component 7 includes a fixed seat 71 mounted on a connecting rod 66, a connecting seat 72 rotatably mounted on the fixed seat 71, a plurality of rotating rods 73 rotatably mounted on the mounting block 64, a plurality of rotating rods 73 having interlocking rotating gears 74 on the plurality of rotating rods 73, a control screw 75 mounted on the rotating rod 73, the control screw 75 passing through the mounting block 64 and connecting to the connecting seat 72, the control screw 75 being movably connected to the mounting block 64, and the control screw 75 being threadedly connected to the rotating rods 73.

[0042] The advantage of the unfolding part 7 is that it can retract the support plate 3, making it easy to move the support plate 3 and preventing the support plate 3 from colliding with the support ribs on the casting mold 2.

[0043] The driving component 8 includes multiple fixed plates 81 disposed within the material guide hopper 13. A pressure plate 82 is rotatably disposed on the fixed plate 81, and the pressure plate 82 is connected to the fixed plate 81 via a torsion spring. Air chambers 83 are disposed on both sides of the material guide hopper 13. A piston plate 84 is slidably disposed within the air chamber 83, and a return spring 810 is disposed within the air chamber 83. A trigger rod 85 is disposed on the piston plate 84, and the trigger rod 85 passes through the material guide hopper 13 and is slidably connected to the material guide hopper 13. An air guide pipe 86 is disposed on the air chamber 83, and the air guide pipe 86 is a flexible hose. A driving chamber 87 is disposed on the mounting block 64, and the driving chamber 87 is connected to the air guide pipe 86. A piston plate 88 is slidably disposed within the driving chamber 87, and a driving rack 89 is disposed on the piston plate 88 that meshes with the rotating gear 74.

[0044] When pouring concrete, the workers first move the hopper filled with concrete to the top of the pouring mold 2 using a gantry crane. Then, they align the outlet of the concrete hopper with the guide hopper 13. After that, they pour the concrete into the pouring mold 2. When the amount of concrete reaches a certain level, they close the outlet of the hopper, move the hopper to another location in the pouring mold 2, and pour the concrete again. This process is repeated.

[0045] In use, the drive motor 55 is first started to drive the drive screw 54 to rotate, which in turn drives the sliding block 53 to move. The movement of the sliding block 53 drives the guide frame 12 and the guide bin 13 to move, which in turn drives the extension rod 57 and the positioning plate 62 set on the extension rod 57 to move in the through groove 61. When pouring concrete, the concrete enters the casting mold 2 through the guide bin 13. When the concrete enters the guide bin 13, it will first press the pressure plate 82, causing the pressure plate 82 to deflect and press the trigger rod 85. When the trigger rod 85 is pressed, it will push the piston plate 1 84 to move in the air chamber 83, and press the gas in the air chamber 83 into the drive chamber 87 through the air pipe 86. When the drive chamber 87 is filled with air, the gas pushes the piston plate 2 88 to move, which in turn drives the drive rack 89 set on the piston plate 2 88 to move.

[0046] The drive rack 89 moves, pushing the rotating gear 74 meshing with it to rotate. The rotating gear 74 rotates, simultaneously pushing the rotating rod 73 to rotate, further pushing the control screw 75 threadedly connected to the rotating rod 73 to move. While the control screw 75 moves, it pushes the connecting rod 66 to deflect. While the connecting rod 66 deflects, it pushes the support plate 3 to move. After the support plate 3 moves, it contacts the casting mold 2 and supports the casting mold 2. At the same time, the advantage of the extrusion rod 68 slidingly set on the support plate 3 is that it can avoid the support ribs on the casting mold 2.

[0047] When the hopper stops feeding, the pressure plate 82 resets under the action of the torsion spring, while the piston plate 84 resets under the push of the reset spring 810, which in turn drives the connecting rod 66 and the support plate 3 to reset, making it easier to move the support plate 3 in the future.

[0048] The adjustment component 9 includes a sensor 10 installed on the material guide hopper 13, which senses the amount of concrete poured at the same position in the pouring mold 2. The positioning plate 62 is provided with an adjustment component 11, which drives the support plate 3 to move up and down.

[0049] The sensing element 10 includes a positioning block 101 on the material guide hopper 13. A rotating shaft 102 is rotatably mounted on the positioning block 101. An extension groove 103 is provided on the material guide hopper 13. Multiple rotating plates 104 are provided on the rotating shaft 102. A winding wheel 105 is provided on the rotating shaft 102. Guide plates 106 are provided on both the material guide hopper 13 and the material guide frame 12. A traction rope 107 is provided on the winding wheel 105. The traction rope 107 passes through the guide plate 106 and is movably connected to the guide plate 106.

[0050] The advantage of setting the sensor 10 is that it can synchronously adjust the support height of the support plate 3 according to the height of the concrete in the casting mold 2. As the height of the concrete increases, the load borne by the casting mold 2 gradually increases. In order to maintain the stability of the casting mold 2 and prevent it from deforming or overturning due to excessive load.

[0051] The adjusting component 11 includes a movable lead screw 111 rotatably disposed in a sliding groove 63. The movable lead screw 111 passes through a mounting block 64 and is threadedly connected to the mounting block 64. A spring box 112 is disposed in the sliding groove 63. The spring box 112 is rotatably connected to the movable lead screw 111. A spring spring 113 is disposed in the spring box 112. One end of the spring spring 113 is connected to the movable lead screw 111. A winding wheel 114 is disposed on the movable lead screw 111. A traction rope 107 passes through a positioning plate 62 and is connected to the winding wheel 114. The traction rope 107 is movably connected to the positioning plate 62. A synchronization groove 115 is opened on the extension rod 57. One end of the movable lead screw 111 extends into the synchronization groove 115 and is rotatably connected to the synchronization groove 115. A synchronization pulley 116 is disposed at one end of the movable lead screw 111 located in the synchronization groove 115. A synchronization belt 117 is disposed on the synchronization pulley 116.

[0052] As the concrete falls, it pushes the rotating plate 104 to rotate. The rotation of the rotating plate 104 synchronously drives the rotating shaft 102 to rotate. The rotation of the rotating shaft 102 synchronously drives the winding wheel 105 to rotate. The winding wheel 105 rotates to wind up the traction rope 107. At this time, under the pull of the traction rope 107, the winding wheel 114 rotates and synchronously drives the moving screw 111 to rotate. At this time, the spring 113 stores power. As the moving screw 111 rotates, it drives the mounting block 64 to slide in the sliding groove 63, thereby changing the support height of the support plate 3. After the concrete is poured, the workers close the discharge port of the hopper. At this time, the rotating plate 104 stops rotating, and the spring 113 releases its force to drive the moving screw 111 to rotate in the opposite direction, thereby driving the mounting block 64 to reset. The advantage of setting up the synchronous pulley 116 and the synchronous belt 117 is that they can drive the support plates 3 on both sides of the pouring mold 2 to rise and fall synchronously, ensuring the stability of the support.

[0053] When in use, the staff will first move the hopper filled with concrete to the top of the casting mold 2 using a gantry crane. Then, the discharge port of the concrete hopper will be aligned with the guide hopper 13. After that, concrete will be poured into the casting mold 2. When the concrete reaches a certain amount, the discharge port of the hopper will be closed, and the hopper will be moved to another location of the casting mold 2. The concrete will be poured again, and the cycle will be repeated.

[0054] During pouring, the drive motor 55 is first started to drive the drive screw 54 to rotate, which in turn drives the sliding block 53 to move. The movement of the sliding block 53 drives the guide frame 12 and the guide bin 13 to move, which in turn drives the extension rod 57 and the positioning plate 62 set on the extension rod 57 to move in the through groove 61. When pouring concrete, the concrete enters the pouring mold 2 through the guide bin 13. When the concrete enters the guide bin 13, it will first press the pressure plate 82, causing the pressure plate 82 to deflect and press the trigger rod 85. When the trigger rod 85 is pressed, it will push the piston plate 1 84 to move in the air chamber 83, and press the gas in the air chamber 83 into the drive chamber 87 through the air pipe 86. When the drive chamber 87 is filled with air, the gas pushes the piston plate 2 88 to move, which in turn drives the drive rack 89 set on the piston plate 2 88 to move.

[0055] The drive rack 89 moves, pushing the rotating gear 74 meshing with it to rotate. The rotating gear 74 rotates, simultaneously pushing the rotating rod 73 to rotate, further pushing the control screw 75 threadedly connected to the rotating rod 73 to move. While the control screw 75 moves, it pushes the connecting rod 66 to deflect. While the connecting rod 66 deflects, it pushes the support plate 3 to move. After the support plate 3 moves, it contacts the casting mold 2 and supports the casting mold 2. At the same time, the advantage of the extrusion rod 68 slidingly set on the support plate 3 is that it can avoid the support ribs on the casting mold 2.

[0056] When the hopper stops feeding, the pressure plate 82 resets under the action of the torsion spring, while the piston plate 84 resets under the push of the reset spring 810, which in turn drives the connecting rod 66 and the support plate 3 to reset, making it easier to move the support plate 3 in the future.

[0057] As the concrete falls, it pushes the rotating plate 104 to rotate. The rotation of the rotating plate 104 synchronously drives the rotating shaft 102 to rotate. The rotation of the rotating shaft 102 synchronously drives the winding wheel 105 to rotate. The winding wheel 105 rotates to wind up the traction rope 107. At this time, under the pull of the traction rope 107, the winding wheel 114 rotates and synchronously drives the moving screw 111 to rotate. At this time, the spring 113 stores power. As the moving screw 111 rotates, it drives the mounting block 64 to slide in the sliding groove 63, thereby changing the support height of the support plate 3. After the concrete is poured, the workers close the discharge port of the hopper. At this time, the rotating plate 104 stops rotating, and the spring 113 releases its force to drive the moving screw 111 to rotate in the opposite direction, thereby driving the mounting block 64 to reset. The advantage of setting up the synchronous pulley 116 and the synchronous belt 117 is that they can drive the support plates 3 on both sides of the pouring mold 2 to rise and fall synchronously, ensuring the stability of the support.
