Description

Technical Field

[0001] This application relates to the field of aqueduct construction, and in particular to a seamless frame column construction process and structure. Background Technology

[0002] An aqueduct is a structure used to transport water, typically spanning rivers, streams, or other topographical obstacles to ensure the smooth flow of water resources to where they are needed. This facilitates the rational use of water resources and meets the water demands of various sectors, including agriculture, industry, and urban life. When constructing a large aqueduct structure, the framework columns are poured first. Multiple framework columns are placed at equal intervals along the aqueduct's orientation. Then, the pre-cast aqueduct sections are hoisted onto the framework columns one by one to form a continuous aqueduct.

[0003] The frame column consists of two symmetrically arranged columns, with multiple tie beams spaced apart along the height of the columns. A cap beam is located at the top of each column to support the aqueduct body. Since the height of the frame column is typically between 13 and 15 meters, the traditional casting method is multi-segment construction. This involves starting from the bottom of the frame column, erecting the column formwork, pouring the concrete, and then continuing to erect the formwork upwards after the bottom concrete has solidified, repeating this process multiple times until the frame column is fully formed.

[0004] For the aforementioned technologies, segmented frame columns require multiple waiting periods for concrete to solidify, resulting in a longer construction cycle and gaps between adjacent segments, affecting the quality of the pouring. Summary of the Invention

[0005] To address the issues of low efficiency and quality during the casting of frame columns, this application provides a seamless frame column construction process and structure.

[0006] This application provides a seamless frame column construction process and structure, which adopts the following technical solution: A seamless frame column construction process includes the following steps: S1. Casting of cast-in-place piles: Using a total station to survey and set out the construction site, determine the location of the pile hole, drill the hole with a rotary drilling rig, insert a sleeve into the hole to support the hole wall, then insert the reinforcing cage of the cast-in-place pile into the hole, and pour concrete to form the cast-in-place pile. S2. Construct a support platform, connect the support platform steel cage to the reserved steel bars at the top of the cast-in-place pile, tie the precast steel bars of the column to the top of the support platform steel cage, construct the support platform casting formwork around the support platform steel cage, and pour concrete into it to form the support platform and the cast-in-place pile as one piece. After the concrete has completely solidified, remove the support platform casting formwork. S3. Erect the column reinforcement bars, and continue to connect the column reinforcement cage to the column precast reinforcement bars until the column reinforcement cage reaches the predetermined height. S4. Install column formwork and tie beam formwork. Install the column formwork around the column reinforcement cage and install the tie beam formwork between the two column formworks. The column formwork has a pouring window on the side near the tie beam formwork. The tie beam formwork is connected to the pouring window on the two column formworks. Install the tie beam reinforcement cage inside the tie beam formwork and connect the tie beam reinforcement cage to the column reinforcement cage. S5. Pour concrete into the columns and tie beams. Pour concrete into the tie beam formwork through the auxiliary pouring device, so that the concrete flows into the column formwork through the tie beam formwork. During the pouring process, the concrete is continuously vibrated by the auxiliary pouring device until the concrete fills the tie beam formwork and column formwork, and then the tie beam formwork is closed. S6. Repeat S4 and S5 until the column reaches the specified height; S7. After the concrete in the column formwork and tie beam formwork has solidified, install the cap beam formwork on top of the column formwork, build the cap beam reinforcement cage inside the cap beam formwork, connect the cap beam reinforcement cage with the column reinforcement cage, pour concrete into the cap beam formwork, and vibrate it. S8. Dismantle the formwork. After the concrete inside the cap beam formwork has solidified, dismantle the cap beam formwork, tie beam formwork, and column formwork in sequence.

[0007] By adopting the above technical solution, the construction of the support platform can improve the stability of the bottom of the frame column when pouring the column. The concrete can be poured and vibrated in sections to fully fill the formwork. After all the pouring is completed, the quality of the pouring is improved. After all the concrete in the formwork has solidified, the formwork is removed, so that the frame column is formed in one go, forming a seamless frame column, thereby improving the efficiency and quality of the pouring.

[0008] Optionally, the column template is provided with a connecting part at the pouring window, and the tie beam template is detachably connected to the connecting part.

[0009] By adopting the above technical solution and setting up connecting parts, the installation and disassembly of the tie beam formwork are facilitated, thereby improving the efficiency of the pouring construction.

[0010] Optionally, the column template is vertically divided into two parts, with the dividing surface along the middle of the casting window.

[0011] By adopting the above technical solution, when installing the column formwork, the two parts of the column formwork are fastened together from both sides of the column reinforcement cage. Since the column reinforcement cage is relatively high, the fastening method facilitates the installation of the support formwork.

[0012] Optionally, a connecting template is provided between two vertically adjacent column templates. The connecting wooden board is detachably connected to the column template. The outer contour of the connecting template is the same as that of the column template. The connecting template is vertically divided into two parts, and the dividing surface of the connecting template is offset from the dividing surface of the column template.

[0013] By adopting the above technical solution, when connecting two column templates, the connecting template is used for transition, and the dividing surface of the connecting template is staggered with the dividing surface of the column template. This can prevent the dividing surfaces of the templates of the same column from being located on the same plane, thereby reducing the possibility of column template cracking.

[0014] Optionally, the auxiliary pouring device includes a support, a pouring hopper, a sliding assembly, and a vibrating assembly. The support is detachably connected to the tie beam formwork. The pouring hopper, sliding assembly, and vibrating assembly are all mounted on the support. The pouring hopper is slidably connected to the support, and the sliding direction is along the length of the tie beam formwork. The sliding assembly is used to drive the pouring hopper to slide, and the vibrating assembly is used to vibrate the concrete inside the tie beam formwork.

[0015] By adopting the above technical solution, when pouring concrete for the tie beam formwork, the concrete supply pipe is fixed on the pouring hopper, and the sliding component drives the pouring hopper to move back and forth along the length of the tie beam formwork, so that the pouring hopper supplies concrete to the tie beam formwork evenly. During this period, the vibration component continuously vibrates the concrete in the tie beam formwork, so that the concrete can fully fill the tie beam formwork and the corresponding column formwork, thereby improving the quality of concrete pouring.

[0016] Optionally, the sliding assembly includes a sliding plate, a drive screw, a guide rod, and a drive motor. The casting hopper is disposed on the sliding plate, and the sliding plate is slidably connected to the support. The drive screw and the guide rod are both arranged along the sliding direction of the sliding plate. The drive screw is rotatably connected to the support, and the guide rod is fixedly connected to the support. The drive screw and the guide rod both pass through the sliding plate. The drive screw is threadedly connected to the sliding plate, and the guide rod is rotatably connected to the sliding plate. The drive motor is disposed on the support and is used to drive the drive screw to rotate.

[0017] By adopting the above technical solution, when the sliding component drives the pouring bucket to move, the drive motor is started, the drive motor drives the drive screw to rotate, so that the sliding plate drives the drive to move. During the movement, the guide rod limits the sliding plate to improve the stability of the sliding plate during movement.

[0018] Optionally, the vibration assembly includes an installation rod, a vibration rod, and a vibration drive assembly. The installation rod is arranged along the length direction of the tie beam template and is movably mounted on the support. Multiple vibration rods are provided and spaced apart along the length direction of the installation rod. The vibration drive assembly is used to drive the installation rod to swing.

[0019] By adopting the above technical solution, when the vibrating assembly vibrates the concrete in the tie beam formwork, the vibrating drive assembly drives the installation rod to swing, which in turn drives multiple vibrating rods to swing, thereby achieving multi-directional vibration of the concrete in the tie beam formwork.

[0020] Optionally, the vibration drive assembly includes a driven rod, a first gear, a second gear, a half gear, and a drive rack. The driven rod is arranged along the width direction of the tie beam template and is rotatably connected to the support. The first gear is coaxially mounted on the drive screw, and the second gear is coaxially mounted on the driven rod. The first gear and the second gear mesh. The half gear is coaxially mounted on the driven rod. The mounting rod is connected to the drive rack, and the drive rack is slidably connected to the support. The sliding direction is along the width direction of the tie beam template. The half gear and the drive rack mesh intermittently. The support is provided with an elastic element for driving the drive rack to reset.

[0021] By adopting the above technical solution, when the sliding assembly drives the sliding plate to move, the drive screw rotates, the drive screw drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the driven rod to rotate, causing the half gear on the driven rod to rotate. When the half gear meshes with the drive rack, it will drive the drive rack to move. When the half gear does not mesh with the drive rack, the elastic element drives the drive rack to reset, thereby causing the drive rack to reciprocate, thereby driving the mounting rod to swing back and forth. That is, the drive motor can drive the sliding plate to move while also driving the vibrating rod to swing.

[0022] Optionally, a mounting block is provided between the vibrating rod and the mounting rod. The mounting block is slidably connected to the mounting rod, and the sliding direction is along the length direction of the mounting rod. The vibrating rod is slidably connected to the mounting block, and the sliding direction is vertical. The mounting block is provided with a first locking member and a second locking member. The first locking member is used to lock the mounting block, and the second locking member is used to lock the vibrating rod.

[0023] By adopting the above technical solution, before pouring concrete for the tie beam formwork, the installation block is slidable so that the vibrator on the installation block is positioned in the gap between the reinforcing bars of the tie beam reinforcement cage. The first locking piece is used to lock the position of the installation block, and then the vibrator is slid downward to allow it to enter the tie beam formwork. The second locking piece is used to lock the vibrator, which facilitates the vibration of the concrete inside the tie beam formwork. After vibration is completed, the vibrator is slid upward and locked with the second locking piece, which facilitates the disassembly of the auxiliary pouring device.

[0024] A seamless frame column structure is prepared using the aforementioned seamless frame column construction process.

[0025] By adopting the above technical solution and the seamless frame column construction process, the seamless frame column structure is connected to the ground at the bottom through cast-in-place piles and bearing platforms. The part above the ground consists of integrally formed columns, tie beams and crossbeams, which makes the frame column structure more stable and has a stronger compressive strength. Moreover, the integral design makes the frame column more aesthetically pleasing.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up column formwork, pouring windows, and tie beam formwork, concrete can flow from the tie beam formwork to the column formwork during the pouring of tie beams and columns. This also facilitates the vibration of the concrete. After pouring, the top of the tie beam formwork is closed, which also closes the pouring windows. The next layer of formwork is then overlapped, and pouring continues. By repeating the above steps, the frame columns can be poured in sections, increasing the filling degree of concrete in the formwork and achieving one-time molding, thereby improving the pouring efficiency and quality of the frame columns. 2. By dividing the column formwork and connecting formwork into two parts, the column formwork can be easily fastened to the perimeter of the column reinforcement cage during installation. The connecting formwork is divided and the dividing surfaces of the connecting formwork are staggered with those of the column formwork, which can prevent the dividing surfaces of the same column formwork from being on the same plane and reduce the possibility of column formwork cracking. 3. By setting up a pouring hopper, a sliding assembly, a vibrating rod, and a vibration drive assembly, when pouring concrete into the tie beam formwork, the sliding assembly drives the pouring hopper to move back and forth along the length of the tie beam formwork, so that the pouring hopper can evenly pour concrete into the interior of the tie beam formwork. At the same time, the vibration drive assembly drives the vibrating rod to swing inside the tie beam formwork, so that the vibrating rod can vibrate the concrete inside the tie beam formwork, thereby enabling the concrete to fully fill the tie beam formwork and column formwork, improving the pouring quality of the frame column.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0031] This application discloses a construction process for seamless frame columns. (Refer to...) Figure 1 The construction process for seamless frame columns includes the following steps:

[0032] S1. Casting of cast-in-place piles: Using a total station to survey and set out the construction site, determine the location of the pile hole, drill the hole with a rotary drilling rig, insert a sleeve into the hole to support the hole wall, then insert the reinforcing cage of the cast-in-place pile into the hole, and pour concrete to form the cast-in-place pile. S2. Construct bearing platform 1, connect the bearing platform steel cage to the reserved steel bars at the top of the cast-in-place pile, tie the precast steel bars of the column to the top of the bearing platform steel cage, construct the bearing platform casting formwork around the bearing platform steel cage, and pour concrete into it so that bearing platform 1 and cast-in-place pile are formed as one piece. After the concrete has completely solidified, remove the bearing platform casting formwork. S3. Erect the column reinforcement cage 21, and continue to connect the column reinforcement cage 21 to the precast column reinforcement until the column reinforcement cage 21 reaches the predetermined height. S4. Install column formwork 22 and tie beam formwork 32. Install column formwork 22 around column reinforcement cage 21 and install tie beam formwork 32 between the two column formwork 22. The side of column formwork 22 closest to tie beam formwork 32 is provided with a pouring window 221. Tie beam formwork 32 is connected to the pouring window 221 on the two column formwork 22. Install tie beam reinforcement cage 31 in tie beam formwork 32 and connect tie beam reinforcement cage 31 to column reinforcement cage 21. S5. Pour concrete into the columns and tie beams. Pour concrete into the tie beam formwork 32 through the auxiliary pouring device 5, so that the concrete flows into the column formwork 22 through the tie beam formwork 32. During the pouring process, the concrete is continuously vibrated by the auxiliary pouring device 5 until the concrete fills the tie beam formwork 32 and the column formwork 22, and the tie beam formwork 32 is closed. S6. Repeat S4 and S5 until the column reaches the specified height; S7. After the concrete in the column formwork 22 and tie beam formwork 32 has solidified, install the cap beam formwork 42 on the top of the column formwork 22, build the cap beam reinforcement cage 41 inside the cap beam formwork 42, connect the cap beam reinforcement cage 41 to the column reinforcement cage 21, pour concrete into the cap beam formwork 42, and vibrate it. S8. Dismantle the formwork. After the concrete inside the formwork has solidified, dismantle the cap beam formwork 42, tie beam formwork 32 and column formwork 22 in sequence.

[0033] Specifically, refer to Figure 2 After the construction of the support platform 1 is completed, the top of the support platform 1 is reserved with precast steel bars for columns (not shown in the figure). Two sets of precast steel bars for columns are symmetrically arranged and correspond to the installation positions of the two columns respectively. Two sets of column steel cages 21 are tied to the two sets of precast steel bars for columns so that the two sets of column steel cages 21 reach the predetermined positions and heights.

[0034] Reference Figure 3 and Figure 4After the installation of the column reinforcement cage 21 is completed, the column formwork 22 is installed around the column reinforcement cage 21. The column formwork 22 is cylindrical in shape. The top and bottom of the column formwork 22 are provided with connecting rings. Multiple mounting holes are evenly opened on the connecting rings for bolts to pass through, so as to facilitate the connection of the column formwork 22 with other structural components. Multiple crisscrossing reinforcing ribs are provided around the column formwork 22 to improve its strength. A pouring window 221 is provided on one side of the column formwork 22 near another column formwork 22. The pouring window 221 is rectangular in shape. A connecting part 222 is welded to the column formwork 22 at the pouring window 221. The connecting part 222 is U-shaped and the opening faces upward. The connecting part 222 is welded with crisscrossing reinforcing ribs on its periphery. Connecting ear plates are provided at the top and end edges of the connecting part 222. Multiple mounting holes are evenly provided on the connecting ear plates to facilitate the connection of the tie beam formwork 32 to the connecting part 222.

[0035] Reference Figure 2 and Figure 3 The bottom of both the column reinforcement cage 21 and the column formwork 22 is flared, i.e., truncated cone-shaped, which can increase the contact area between the column and the support platform 1, thereby improving the stability of the frame column.

[0036] Reference Figure 4 The column formwork 22 is vertically divided into two parts, and the two parts are installed symmetrically along the dividing surface, which is located in the middle of the pouring window 221 and the middle of the connecting part 222. Both the column formwork 22 and the connecting part 222 have mounting plates at the edges of the dividing sections, and each mounting plate has multiple mounting holes. When installing the column formwork 22, the two parts of the column formwork 22 are fastened together by the two sides of the column reinforcement cage 21, and then fixed by bolts passing through the mounting holes.

[0037] Reference Figure 3 and Figure 4 A connecting template 23 is provided between two adjacent vertical column templates 22. The connecting template 23 is cylindrical with the same diameter as the column template 22. The height of the connecting template 23 is 0.1~0.25 meters; in this embodiment, the height of the connecting template 23 is 0.15 meters. Connecting rings are provided at the top and bottom edges of the connecting template 23. Multiple mounting holes are evenly distributed on the connecting rings to facilitate the insertion of bolts, thus fixing the connecting rings on the connecting template 23 to the connecting rings on the column template 22. The connecting template 23 is vertically divided into two identical parts. When installing the connecting template 23, the dividing surfaces of the connecting template 23 are offset from the dividing surfaces of the column template 22. The connecting template 23 provides a transition between two vertically adjacent column templates 22, preventing the dividing surfaces of the templates for the same column from being on the same plane and reducing the possibility of cracking of the column template 22.

[0038] Reference Figure 5 The tie beam template 32 is located between two connecting parts 222 at the same height. The tie beam template 32 is U-shaped with the opening facing upward. Multiple crisscrossing reinforcing ribs are welded to the periphery of the tie beam template 32. Connecting ear plates are welded to the edges at both ends and the top edge of the tie beam template 32. Multiple mounting holes are evenly opened on the connecting ear plates. The connecting ear plates at the ends of the tie beam template 32 are fixedly connected to the connecting ear plates at the ends of the connecting parts 222 by bolts, thereby realizing the installation of the tie beam template 32.

[0039] Reference Figure 5 After the installation of the tie beam formwork 32 is completed, the connecting ring at the bottom of the column formwork 22 is fixedly connected to the bearing platform 1 with bolts, and a leveling layer is made at the bottom of the column formwork 22 with mortar to reduce the possibility of grout leakage at the column base.

[0040] Reference Figure 5 A tie beam reinforcement cage 31 is built inside the tie beam formwork 32, and the tie beam reinforcement cage 31 is tied and fixed to the column reinforcement cages 21 on both sides, so that the connection between the tie beam and the column after casting is more stable.

[0041] Reference Figure 5 Before pouring concrete into the tie beam formwork 32, an auxiliary pouring device 5 is installed on the tie beam formwork 32 so that the concrete can be poured evenly into the tie beam formwork 32 and flow into the column formwork 22 at both ends. At the same time, the auxiliary pouring device 5 continuously vibrates the concrete so that the concrete can be filled more fully into the tie beam formwork 32 and the column formwork 22, thereby improving the pouring quality of the frame column.

[0042] Reference Figure 6 After the tie beam formwork 32 is poured, the top of the tie beam formwork 32 and the connecting part 222 is closed with a cover plate. The upper column formwork 22 and tie beam formwork 32 are then installed and poured until the column formwork 22 reaches the predetermined height.

[0043] Reference Figure 1The cap beam formwork 42 is rectangular in shape with its opening facing upwards. Two clearance holes are provided at the bottom of the cap beam formwork 42, through which the column reinforcement cage 21 enters the interior of the cap beam formwork 42. Multiple bolts are pre-installed around the clearance holes at the bottom of the cap beam formwork 42. These bolts are matched with the mounting holes on the connecting rings at the top of the two column formworks 22, thus fixing the cap beam formwork 42 to the two column formworks 22, thereby completing the installation of the cap beam formwork 42. After the cap beam formwork 42 is installed, the cap beam reinforcement cage 41 is installed inside the cap beam formwork 42 and fixedly connected to the column reinforcement cages 21 at both ends, making the cap beam and columns a single unit. Finally, concrete is poured into the cap beam formwork 42 and vibrated. After all the concrete in the formwork has solidified, the cap beam formwork 42, tie beam formwork 32, and column formwork 22 are disassembled in sequence to complete the construction of the frame columns.

[0044] Reference Figure 7 The auxiliary pouring device 5 includes a support 51, a pouring hopper 52, a sliding assembly 53, and a vibrating assembly, all of which are mounted on the support 51. The support 51 is generally rectangular, with connecting lugs welded to both sides of its bottom. These lugs are identical in shape and size to the connecting lugs on the top of the tie beam template 32. The connecting lugs of the support 51 have mounting holes of corresponding position and size to those on the connecting lugs on the top of the tie beam template 32. The support 51 is fixedly connected to the tie beam template 32 by bolts passing through these mounting holes. The pouring hopper 52 is a rectangular hopper, wider at the top and narrower at the bottom. The pouring hopper 52 is slidably connected to the support 51, sliding along the length of the support 51. A pipe clamp (not shown in the figure) is installed inside the pouring hopper 52.

[0045] When pouring concrete into the tie beam formwork 32, the concrete delivery pipe is fixed in the pouring hopper 52 by the pipe clamp, thereby supplying concrete to the pouring hopper 52. The sliding component 53 drives the pouring hopper 52 to move back and forth, so that the pouring hopper 52 pours concrete evenly into the tie beam formwork 32. The vibration component continuously vibrates the concrete, so that the concrete can fully fill the tie beam formwork 32 and the column formwork 22.

[0046] Reference Figure 7 and Figure 8The sliding assembly 53 includes a sliding plate 531, a drive screw 532, a guide rod 533, and a drive motor 534. The sliding plate 531 is a rectangular plate with a through hole in the middle for the bottom of the pouring hopper 52 to be inserted. The pouring hopper 52 is inserted into the sliding plate 531 and concrete is poured into the sliding plate 531 through the through hole. The drive screw 532 is a reciprocating lead screw. Both the drive screw 532 and the guide rod 533 are arranged along the sliding direction of the sliding plate 531 and are located at the same height. The drive screw 532 is rotatably connected to the bracket 51, and the guide rod 533 is fixedly connected to the bracket 51. Both the drive screw 532 and the guide rod 533 pass through the sliding plate 531. The sliding plate 531 is slidably connected to the guide rod 533 and threadedly connected to the drive screw 532. The drive motor 534 is a servo motor. The drive motor 534 is fixed to one end of the bracket 51 by bolts, and the output end of the drive motor 534 is fixedly connected to the drive screw 532.

[0047] When the sliding assembly 53 drives the pouring bucket 52 to move, the drive motor 534 is started. The drive motor 534 drives the drive screw 532 to rotate, so that the sliding plate 531 moves back and forth along the drive screw 532, thereby realizing the uniform pouring of concrete into the tie beam formwork 32 by the pouring bucket 52.

[0048] Reference Figure 7 and Figure 8 The vibration assembly includes an installation rod 54, vibration rods 55, and a vibration drive assembly 56. The installation rod 54 is a round rod and is arranged parallel to the drive screw 532. The vibration rod 55 includes a vertical part and a horizontal part. The bottom of the horizontal part is welded to the bottom of the vertical part. The length direction of the horizontal part is along the sliding direction of the pouring hopper 52. Multiple vibration rods 55 are arranged along the length of the installation rod 54 and are spaced apart. The vibration drive assembly 56 is used to drive the installation rod 54 to swing. The installation rod 54 drives the multiple vibration rods 55 to swing, so that the multiple vibration rods 55 vibrate the concrete at different positions in the tie beam formwork 32.

[0049] Reference Figure 8 A mounting block 551 is provided between the vibrating rod 55 and the mounting rod 54. The mounting block 551 is slidably connected to the mounting rod 54, and the sliding direction is along the length direction of the mounting rod 54. The mounting block 551 can rotate around the mounting rod 54. The vibrating rod 55 is slidably connected to the mounting block 551, and the sliding direction is along the length direction of the vertical part of the vibrating rod 55. The mounting block 551 is provided with a first locking member 552 and a second locking member 553. Both the first locking member 552 and the second locking member 553 are locking bolts and are threadedly connected to the mounting block 551. The first locking member 552 is located at the top of the mounting block 551 and can abut against the mounting rod 54. The second locking member 553 is located on one side of the mounting block 551 and can abut against the vertical part of the vibrating rod 55.

[0050] Before vibration, slide the mounting block 551 to offset the vibrating rod 55 on the mounting block 551 from the reinforcing bars of the tie beam reinforcement cage 31, thus ensuring that the vibrating rod 55 can smoothly enter the tie beam reinforcement cage 31. Rotating the mounting block 551 can adjust the angle of the vibrating rod 55, so that the lateral part of the vibrating rod 55 is in different positions, increasing the effective range of the vibrating rod 55. After adjustment, rotate the first locking piece 552 to lock the mounting block 551 onto the mounting rod 54. Then slide the vibrating rod 55 downward to enter the tie beam reinforcement cage 31, and rotate the second locking piece 553 to lock the vibrating rod 55, thus completing the preparation work before the vibrating rod 55 is used for vibration.

[0051] Reference Figure 7 and Figure 8 The vibratory drive assembly 56 includes a driven rod 561, a first gear 562, a second gear 563, a half gear 564, a drive rack 565, and an elastic element 566. The driven rod 561 is a round rod located directly below the drive screw 532 and is rotatably connected to the bracket 51. The first gear 562 is coaxially arranged with the drive screw 532, located at the end of the bracket 51 furthest from the drive motor 534. The end of the drive screw 532 furthest from the drive motor 534 extends out of the bracket 51, and the first gear 562 is fixedly connected to the drive screw 532. The end of the driven rod 561 furthest from the drive motor 534 extends out of the bracket 51, and the second gear 563 is fixedly connected to the driven rod 561, meshing with the first gear 562.

[0052] Reference Figure 8 The half-gear 564 is an incomplete gear, coaxially arranged with and fixedly connected to the driven rod 561. The drive rack 565 is located directly below the half-gear 564 and is arranged laterally, allowing the half-gear 564 and the drive rack 565 to mesh. One end of the drive rack 565 extends out of the bracket 51 and is slidably connected to the bracket 51, with the sliding direction along the width direction of the bracket 51. The other end of the drive rack 565 is fixedly connected to the mounting rod 54. Two sets of half-gears 564 and drive racks 565 are spaced apart along the length of the bracket 51. The ends of the two drive racks 565 protruding from the bracket 51 are connected to a connecting rod 567, which is welded to the two drive racks 565. The elastic element 566 is a spring. There are two elastic elements 566, which are respectively sleeved on the two drive racks 565. One end of the elastic element 566 is welded to the bracket 51, and the other end is welded to the connecting rod 567.

[0053] When the sliding assembly 53 moves the pouring bucket 52, the drive screw 532 rotates, which in turn drives the driven rod 561 to rotate via the first gear 562 and the second gear 563. This causes the half gear 564 to rotate, and the half gear 564 drives the drive rack 565 to slide toward the connecting rod 567. The elastic element 566 is stretched. When the half gear 564 disengages from the drive rack 565, the drive rack 565 moves in the opposite direction under the action of the elastic element 566, and the half gear 564 continues to rotate. This allows the drive rack 565 to move continuously back and forth, and the drive rack 565 drives the vibrating rod 55 to swing continuously, thereby achieving the vibration of the concrete.

[0054] Reference Figure 8 Infrared emitters 57 are fixed to both sides of the sliding plate 531, and infrared sensors 58 are fixed to both inner sides of the bracket 51 along its length. The infrared emitters 57 and infrared sensors 58 are at the same height. The infrared sensors 58 can receive the infrared rays emitted by the infrared emitters 57 and are electrically connected to the drive motor 534. The infrared emitters 57, infrared sensors 58, and vibrating rod 55 are on the same plane. When the vibrating rod 55 is in the retracted state, it blocks the infrared rays, preventing the infrared sensors 58 from receiving them. The drive motor 534 can only operate when the infrared sensors 58 receive infrared rays; otherwise, the drive motor 534 cannot operate. By setting the infrared emitters 57 and infrared sensors 58, the sliding of the sliding plate 531 by the vibrating rod 55 can be prevented, reducing the possibility of damage to the auxiliary pouring device 5.

[0055] The implementation principle of the seamless frame column construction process and structure in this application embodiment is as follows: When pouring the frame column, the concrete can flow from the tie beam formwork 32 to the column formwork 22 through the pouring window 221, and the concrete is vibrated by the auxiliary pouring device 5. After the pouring is completed, the top of the tie beam formwork 32 is closed, so that the pouring window 221 is also closed. The upper column formwork 22 and tie beam formwork 32 are then built, and the pouring continues. The above steps are repeated, and the cap beam formwork is built and the cap beam is poured. The frame column is poured in sections so that the concrete is fully filled in each formwork and formed in one go, thereby improving the pouring efficiency and quality of the frame column.
