Description

Technical Field

[0001] This application relates to the field of support structures, and in particular to a support structure for post-cast strips in concrete structures. Background Technology

[0002] A post-cast strip is a concrete strip left at appropriate locations in floor slabs, walls, and beams during building construction to prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement, in accordance with design or construction specifications.

[0003] Currently, a related technology discloses a post-pouring strip support structure, including a support frame comprising multiple horizontal and vertical rods. A disc is fixedly fitted onto each vertical rod, and connecting blocks are fixedly installed at both ends of each horizontal rod. Each connecting block is equipped with an insert plate. Both the connecting blocks and the disc have slots for the damped insertion of the insert plates. The connecting blocks are placed on the discs, and then the slots on the discs and connecting blocks are aligned. The insert plates are then inserted into the slots, connecting the horizontal and vertical rods together. Each horizontal and vertical rod is connected to form the support frame. A pad is fixedly installed at the bottom of each vertical rod, and a support plate is fixedly installed at the top. A template is installed on the top side of the support frame, and the support plate supports the template. A pouring opening for the post-pouring strip is pre-reserved on the floor slab. The support frame supports the template via the support plate, thus sealing the bottom side of the pouring opening. Concrete is then poured into the pouring opening, and after the concrete solidifies, the post-pouring strip is formed.

[0004] Regarding the aforementioned technologies, the inventors believe that when connecting vertical and horizontal bars, construction workers need to use a hammer to strike the insert plate. When the insert plate is struck, the support frame vibrates, causing other inserts already inserted into the sockets to loosen. After the inserts loosen, the construction workers need to re-hammer the insert plate, thus increasing the difficulty of connecting the horizontal and vertical bars. Summary of the Invention

[0005] To facilitate the connection of horizontal and vertical bars to form a support frame, this application provides a post-cast strip support structure for concrete structures.

[0006] This application provides a post-cast strip support structure for concrete structures, which adopts the following technical solution:

[0007] A post-cast strip support structure for concrete structures includes a support frame comprising multiple vertical rods and horizontal rods. A pad is fixedly installed at the bottom end of each vertical rod, and a support plate is lifted and lowered at the top end of each vertical rod. A template is provided on the top side of the support frame, and each support plate abuts against the bottom surface of the template. A disc is fixedly fitted onto each vertical rod, and multiple rotating openings are provided on the periphery of the disc. A shaft is rotatably installed between the opposite side walls of each rotating opening, and a pressure plate is fixedly installed on the shaft. A driving mechanism is installed on each vertical rod to drive the pressure plate to rotate towards the vertical rod. First connecting blocks are fixedly installed at both ends of each horizontal rod, abutting against the top surface of the disc. Each first connecting block has a first pressure opening for the pressure plate to pass through. The horizontal rod connects to a disc at the same height as two adjacent vertical rods, and the horizontal rod is located between two adjacent vertical rods.

[0008] By adopting the above technical solution, each vertical rod is erected, and then a horizontal rod is placed between two adjacent vertical rods. The first connecting block rests on the top surface of a disc at the same height on the two adjacent vertical rods, and the pressure plate passes through the first pressure opening. Then, a drive mechanism drives the pressure plates on the same disc to rotate together towards the vertical rod, causing the pressure plates to press tightly against the inner wall of the vertical rod near the first pressure opening, thereby connecting the vertical rod and the horizontal rod. The drive mechanism rotates each pressure plate on the disc together, reducing the possibility of the horizontal and vertical rods separating after vibration of the support frame, thus facilitating the connection of the horizontal and vertical rods to form a support frame.

[0009] Optionally, the driving mechanism includes a driving sleeve and a driving plate. One side of the driving plate is fixedly connected to the side of the pressure plate near the shaft. Both the driving sleeve and the driving plate are located on the bottom surface of the disc. The driving sleeve is threaded onto the vertical rod.

[0010] By adopting the above technical solution, after each pressure plate on the disc passes through the first pressure hole, the rotating drive sleeve moves upward. Then, the top of the drive sleeve pushes the drive plate away from the vertical rod. The drive plate drives the pressure plate to rotate towards the vertical rod, thereby facilitating the connection between the horizontal rod and the vertical rod to form a support frame.

[0011] Optionally, the drive plate is inclined on the side away from the pressure plate, gradually moving away from the shaft from the vertical rod to the side away from the vertical rod.

[0012] By adopting the above technical solution, when the drive sleeve rises, the top of the drive sleeve and the inclined side of the drive plate press against each other, so that the drive plate moves away from the vertical rod and rests on the edge of the top of the drive sleeve, thereby reducing the occurrence of manually pulling the drive plate to avoid the drive sleeve.

[0013] Optionally, the drive sleeve is provided with a plurality of push blocks at one end near the disc, the plurality of push blocks are arranged around the vertical rod, and two adjacent push blocks abut against each other. The drive sleeve is provided with a lifting rod, the lifting rod is threaded through the drive sleeve along the height direction, a rotating groove is opened on the side of the push block near the drive sleeve, a limit plate is fixedly installed at one end of the lifting rod near the push block, a limit ring is fixedly installed at the opening of the rotating groove, the limit plate abuts against the bottom of the rotating groove, the peripheral side wall of the rotating groove and the limit ring, and the limit ring is sleeved on the lifting rod.

[0014] By adopting the above technical solution, the inner wall of the pressure plate, the first pressure port, and the drive plate will wear during use. The greater the wear, the larger the rotation angle required for the pressure plate to press the inner wall of the first pressure port closer to the vertical rod. If the wear of the inner wall of the first pressure port, the pressure plate, and the drive plate on the same disc is different, different rotation angles are required for the pressure plates on the same disc. When the drive sleeve is rotated upward, the drive sleeve drives the drive plate away from the vertical rod through the push block. After one pressure plate on the same disc presses the inner wall of the first pressure port, the lifting rod is rotated upward. The rotation angle of the drive plate is finely adjusted by the lifting rod driving each push block upward, thus facilitating each pressure plate on the same disc to press the inner wall of the first pressure port.

[0015] Optionally, a handle is fixedly installed at the bottom end of the lifting rod.

[0016] By adopting the above technical solution, the handle makes it easy to rotate the lifting rod.

[0017] Optionally, both ends of the shaft are provided with sliders, the end of the shaft is rotatably inserted into the slider, and the rotating opening is fixedly installed with slide bars on both sides. The slider has a groove for the slide bars to slide on the side away from the shaft. The end of the horizontal rod is used to restrict the slider from sliding out of the rotating opening, and the slider abuts against the inner wall of the rotating opening near the vertical rod.

[0018] By adopting the above technical solution, when the drive plate and pressure plate are damaged and need to be replaced, the slider is slid out from the rotating port, thereby removing the drive plate and pressure plate from the disc. Then, a new slider is slid into the rotating port, facilitating the replacement of the pressure plate and drive plate. When the horizontal bar is installed on the two connected vertical bars, the end of the horizontal bar restricts the slider from sliding out of the rotating port, while the slide bar engages with the slide groove, thus keeping the slider fixed inside the rotating port.

[0019] Optionally, it also includes multiple first inclined rods, each of which has a second connecting block fixedly installed at both ends. The second connecting block has a second pressure port for the pressure plate to pass through. The second connecting block abuts against the top surface of the disc. The first inclined rod connects to discs at different heights of two adjacent vertical rods. The first inclined rod is located between two adjacent vertical rods. A first baffle plate is fixedly installed on the bottom side of the second connecting block. The first baffle plate is used to prevent the slider from sliding out of the rotating port.

[0020] By adopting the above technical solution, the first inclined rod is connected to two adjacent vertical rods via the second connecting block, and then the first baffle plate blocks the slider, thereby keeping the slider fixed in the rotation opening. The first inclined rod supports the two adjacent vertical rods, thereby reducing the occurrence of the vertical rods being squeezed and bent.

[0021] Optionally, it also includes multiple second diagonal rods, each with a third connecting block fixedly installed at both ends. The third connecting block has a third pressure opening for the pressure plate to pass through. A second baffle plate is fixedly installed on the bottom side of the third connecting block. Arc plates are hinged to both sides of the second baffle plate. The second baffle plate and the two arc plates enclose a disc. The ends of the first baffle plate and the horizontal rod abut against the arc plates. The second diagonal rod is connected to discs at different heights of two adjacent vertical rods. The second diagonal rod is located outside the two adjacent vertical rods.

[0022] By adopting the above technical solution, the second diagonal rod is installed on the two adjacent vertical rods via the third connecting block. Then, two arc plates surround the circumference of the disk and are pressed together by the first baffle plate and the end of the horizontal rod, thus facilitating the restriction of each slider on the disk from sliding out of the rotation port. The second diagonal rod supports the two adjacent vertical rods, thereby reducing the occurrence of vertical rod bending.

[0023] Optionally, a first clearance opening is provided in the middle of the first diagonal bar, and a second clearance opening is provided in the middle of the second diagonal bar.

[0024] By adopting the above technical solution, when two first diagonal braces are intersecting, their middle sections overlap through a first clearance opening, thereby reducing the possibility of interference between the two first diagonal braces when they intersect. Similarly, when two second diagonal braces are intersecting, their middle sections overlap through a second clearance opening, further reducing the possibility of interference between the two second diagonal braces when they intersect.

[0025] Optionally, a screw is provided on the bottom surface of the support plate, one end of the screw is rotatably inserted into the bottom surface of the support plate, and the other end of the screw is threaded through the top of the vertical rod, and a drive ring is fixedly sleeved on the screw.

[0026] By adopting the above technical solution, rotating the drive ring causes the screw to rotate, thereby raising and lowering the screw. The raising and lowering of the screw causes the support plate to rise and fall, which in turn causes the template to rise and fall, thus facilitating the adjustment of the template height.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. After arranging each vertical rod upright, place the horizontal rod between two adjacent vertical rods, let the first connecting block rest on the disc, and let the pressure plate pass through the first pressure port. Then, the drive mechanism drives the pressure plate to rotate toward the vertical rod, and the pressure plate presses against the inner wall of the first pressure port near the vertical rod, thereby connecting the horizontal rod and the vertical rod to form a support frame. By rotating the pressure rod, the inner wall of the first pressure port is pressed tightly, thereby reducing the possibility of the horizontal rod and the vertical rod separating after the support frame vibrates, and thus facilitating the connection of the horizontal rod and the vertical rod to form a support frame.

[0029] 2. When the pressure plate and drive plate are damaged, slide the slider out of the rotating port to remove the drive plate and pressure plate. Then slide the new slider into the rotating port to install the new drive plate and pressure plate on the disc, which facilitates the replacement of the pressure plate and drive plate.

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0042] This application discloses a post-cast strip support structure for concrete structures.

[0043] Reference Figure 1 A support structure for post-cast strips in concrete structures includes a support frame 6, which comprises multiple horizontal bars 61 and vertical bars 62. In one embodiment of this application, the vertical bars 62 are arranged in two rows, located on both sides of the post-cast strip. The vertical bars 62 in each row are spaced apart along the length of the post-cast strip. In another embodiment, the vertical bars 62 are arranged in three or more rows, with each row of vertical bars 62 spaced apart along the width of the post-cast strip.

[0044] In this embodiment, the horizontal bar 61 is located between two adjacent vertical bars 62 in the same column. In another embodiment, the horizontal bar 61 is also located between two adjacent columns of vertical bars 62.

[0045] Reference Figure 2 , Figure 3 The vertical rod 62 is fixedly fitted with multiple discs 1. In this embodiment, each vertical rod 62 has four discs 1. Multiple rotating openings 2 are provided on the periphery of the discs 1. In this embodiment, the discs 1 have four rotating openings 2. A shaft 3 is provided inside the rotating opening 2. A slider 7 is provided at both ends of the shaft 3. The end of the shaft 3 is rotatably inserted into one side of the slider 7.

[0046] Reference Figure 2 , Figure 3Slide bars 8 are fixedly installed on both opposite side walls of the rotating opening 2. A groove 9 is provided on the side of the slider 7 away from the shaft 3 for the slide bars 8 to slide through. A pressure plate 10 is fixedly installed on the shaft 3. Rotating the pressure plate 10 allows it to move closer to or further away from the vertical rod 62. When the pressure plate 10 is damaged, the slider 7 is slid out of the rotating opening 2. Then, a new slider 7 is slid into the rotating opening 2, facilitating the replacement of the pressure plate 10. The vertical rod 62 is equipped with a drive mechanism 11. The pressure plate 10 is located above the disc 1, and the drive mechanism 11 drives the pressure plate 10 to rotate towards the vertical rod 62.

[0047] Reference Figure 1 , Figure 4 It also includes a first diagonal bar 4 and a second diagonal bar 5. Both ends of the horizontal bar 61 are fixedly installed with a first connecting block 12, and the first connecting block 12 has a first pressure port 15 for the pressure plate 10 to enter.

[0048] Reference Figure 1 , Figure 5 Both ends of the first diagonal rod 4 are fixedly installed with second connecting blocks 13. The second connecting blocks 13 have second pressure openings 16 for the pressure plate 10 to pass through. A first baffle plate 18 is fixedly installed on the bottom side of the second connecting blocks 13.

[0049] Reference Figure 1 , Figure 6 Both ends of the second diagonal rod 5 are fixedly installed with a third connecting block 14, and the third connecting block 14 has a third pressure port 17 for the pressure plate 10 to pass through. A second shielding plate 19 is fixedly installed on the bottom side of the third connecting block 14, and arc plates 20 are hinged on both sides of the second shielding plate 19. The second shielding plate 19 and the two arc plates 20 are used to enclose the disc 1.

[0050] Reference Figure 1 , Figure 7 The second diagonal rod 5 is placed outside the two adjacent vertical rods 62 in the same column, and the third connecting block 14 rests on the top surface of the disk 1 at different heights on the two vertical rods 62. Then, the second blocking plate 19 covers the periphery of the disk 1, thereby blocking a rotation opening 2 to restrict the slider 7 from sliding out of the rotation opening 2. Then, the arc plate 20 is rotated to surround the disk 1.

[0051] After the second inclined rod 5 is placed, the horizontal rod 61 is placed between two adjacent vertical rods 62 in the same column, so that the first connecting block 12 rests on the top surface of the disc 1 at the same height as the two vertical rods 62, and the pressure plate 10 passes through the first pressure hole 15. The end of the horizontal rod 61 abuts against the arc plate 20, thereby restricting the rotation of the arc plate 20 and blocking the rotation hole 2, thereby restricting the slider 7 from sliding out of the rotation hole 2.

[0052] The first diagonal bar 4 is placed between two adjacent columns of vertical bars 62, allowing the second connecting block 13 to rest on the top surface of the disc 1 at different heights of the two vertical bars 62, and allowing the pressure plate 10 to pass through the second pressure opening 16. The first baffle plate 18 abuts against the arc plate 20, thereby pressing the arc plate 20 tightly against the peripheral wall of the disc 1, which serves to restrict the slider 7 from sliding out of the rotation opening 2.

[0053] After the horizontal bar 61, vertical bar 62, first diagonal bar 4, and second diagonal bar 5 overlap, the drive mechanism 11 is activated. The drive mechanism 11 drives each pressure plate 10 on the disc 1 to rotate toward the vertical bar 62, thereby causing each pressure plate 10 on the disc 1 to press the first pressure port 15 near the inner wall of the vertical bar 62, the second pressure port 16 near the inner wall of the vertical bar 62, and the third pressure port 17 near the inner wall of the vertical bar 62, thus connecting the vertical bar 62, horizontal bar 61, first diagonal bar 4, and second diagonal bar 5. The vertical bar 62 and horizontal bar 61 are connected to form a support frame 6, and the first diagonal bar 4 and second diagonal bar 5 are used to strengthen the support frame 6. By rotating the pressure plate 10 to press tightly against the inner wall of the first pressure port 15 near the inner wall of the vertical bar 62, the second pressure port 16 near the inner wall of the vertical bar 62, and the third pressure port 17 near the inner wall of the vertical bar 62, the vibration of the support frame 6 is reduced, thus facilitating the connection of the horizontal bar 61 and vertical bar 62 to form the support frame 6.

[0054] Reference Figure 5 , Figure 6 The first diagonal bar 4 has a first clearance opening 21 in its middle. When two first diagonal bars 4 are intersecting, they avoid each other through the first clearance opening 21, thereby reducing the possibility of interference between the intersecting first diagonal bars 4. The second diagonal bar 5 has a second clearance opening 22 in its middle. When two second diagonal bars 5 are intersecting, they avoid each other through the second clearance opening 22, thereby reducing the possibility of interference between the intersecting second diagonal bars 5.

[0055] Reference Figure 7 , Figure 8 The drive mechanism 11 includes a drive sleeve 111 and a drive plate 112. One side of the drive plate 112 is fixedly connected to the side of the pressure plate 10 near the shaft 3. The weight of the drive plate 112 is greater than the weight of the pressure plate 10, which facilitates the drive plate 112 rotating under gravity and moving to the bottom of the disc 1 when it is not supported by external force. The pressure plate 10 is above the disc 1 and away from the vertical rod 62. By driving the pressure plate 10 away from the vertical rod 62 through the drive plate 112, it is convenient for each pressure plate 10 on the disc 1 to pass through the first pressure port 15, the second pressure port 16, and the third pressure port 17 when the first connecting block 12, the second connecting block 13, and the third connecting block 14 are placed on the disc 1.

[0056] Both the drive sleeve 111 and the drive plate 112 are located on the bottom surface of the disk 1, and the drive sleeve 111 is threaded onto the vertical rod 62. A plurality of push blocks 23 are provided at one end of the drive sleeve 111 near the disk 1, and the push blocks 23 are arranged around the vertical rod 62, with adjacent push blocks 23 abutting against each other. In this embodiment, there are four push blocks 23.

[0057] Reference Figure 9 The drive sleeve 111 is equipped with a lifting rod 24, which is threaded through the drive sleeve 111 along the height direction. A handle is fixedly installed at the bottom end of the screw 31. The lifting rod 24 is rotated by the handle, thereby raising and lowering the lifting rod 24.

[0058] A rotating groove 25 is provided on the side of the push block 23 near the drive sleeve 111, and a limiting plate 26 is fixedly installed on the end of the lifting rod 24 near the push block 23. A limiting ring 27 is fixedly installed at the opening of the rotating groove 25. The limiting plate 26 abuts against the bottom of the rotating groove 25, the peripheral wall of the rotating groove 25, and the limiting ring 27, and the limiting ring 27 is sleeved on the lifting rod 24. By rotating the limiting plate 26 in the rotating groove 25, the occurrence of the push block 23 rotating with the lifting rod 24 is reduced. The limiting plate 26 and the limiting ring 27 are engaged, so that the lifting rod 24 can drive the push block 23 down together when it descends. When the lifting rod 24 rises, the lifting rod 24 pushes the push block 23 upward through the limiting plate 26 to move together.

[0059] Reference Figure 7 The drive plate 112 is inclined on the side away from the pressure plate 10, gradually moving away from the vertical rod 62 and away from the shaft 3. After the first connecting block 12, the second connecting block 13, and the third connecting block 14 rest on the disc 1, and each pressure plate 10 on the disc 1 is inserted into the first pressure port 15, the second pressure port 16, and the third pressure port 17 respectively, the drive sleeve 111 is rotated. The drive sleeve 111 drives each push block 23 to move upwards, and the push block 23 abuts against the inclined side of the drive plate 112, thus facilitating the push block 23 to push the drive plate 112 away from the vertical rod 62 and rotate. The drive plate 112 drives the pressure plate 10 to move towards the vertical rod 62, thereby causing the pressure plate 10 on the disc 1 to press against the inner walls of the first pressure port 15, the second pressure port 16, and the third pressure port 17 respectively, thus facilitating the rotation of each pressure plate 10 on the drive disc 1.

[0060] When the pressure plate 10 is subjected to compression and wear, the inner walls of the first pressure port 15, the second pressure port 16, and the third pressure port 17 will also wear during compression. This requires each pressure plate 10 on the disc 1 to rotate at a different angle, so that each pressure plate 10 on the disc 1 can press the inner walls of the corresponding first pressure port 15, the second pressure port 16, and the third pressure port 17 tightly.

[0061] After the drive sleeve 111 moves upward and a pressure plate 10 on the disc 1 is pressed down, the drive sleeve 111 stops rotating. If one drive plate 112 of the insert rod presses against two push blocks 23, then the drive sleeve 111 is rotated so that one drive plate 112 presses against only one push block 23. After one drive plate 112 presses against only one push block 23, each handle 33 on the drive sleeve 111 is rotated to raise the push block 23, thereby facilitating the rotation of a single pressure plate 10. This ensures that each pressure plate 10 presses against the inner walls of the corresponding first pressure port 15, second pressure port 16, and third pressure port 17.

[0062] Reference Figure 10 A pad 28 is fixedly installed at the bottom end of the vertical rod 62, and the support frame 6 is supported on the ground by the pad 28. The pad 28 is used to distribute the pressure of the support frame 6 on the ground, thereby reducing the possibility of the support frame 6 cracking the ground.

[0063] Reference Figure 1 , Figure 10 A template 29 is provided on the top side of the support frame 6, and a support plate 30 is provided at the top of the vertical rod 62. The support plate 30 abuts against the bottom surface of the template 29.

[0064] A screw 31 is provided on the bottom surface of the support plate 30. One end of the screw 31 is rotatably inserted into the bottom surface of the support plate 30, and the other end of the screw 31 is threaded through the top of the vertical rod 62. The screw 31 is fixedly sleeved with a drive ring 32.

[0065] Rotating the drive ring 32 causes the screw 31 to rotate, thus raising and lowering the screw 31. The raising and lowering of the screw 31 causes the support plate 30 to rise and fall, which in turn causes the formwork 29 to rise and fall, facilitating the adjustment of the formwork 29's height. The bottom side of the pre-reserved pouring opening in the floor slab is sealed by adjusting the height of the formwork 29. Afterwards, construction workers pour concrete into the pouring opening, which solidifies to form a post-pouring strip.

[0066] The implementation principle of the concrete post-cast strip support structure in this embodiment is as follows: Vertical rods 62 are arranged in two rows on both sides of the post-cast strip. Then, a second diagonal rod 5 is placed outside two adjacent vertical rods 62 in the same row. The third connecting blocks 14 at both ends of the second diagonal rod 5 rest on discs 1 at different heights of the two vertical rods 62, allowing the pressure plate 10 to pass through the third pressure opening 17. Afterwards, the arc plates 20 on both sides of the second baffle plate 19 are rotated to surround the disc 1.

[0067] After the second diagonal bar 5 is placed, the horizontal bar 61 is placed between two adjacent vertical bars 62 in the same column, with the first connecting blocks 12 at both ends of the horizontal bar 61 resting on the discs 1 at the same height as the two vertical bars 62. Then, the ends of the horizontal bar 61 are pressed against the arc plate 20. The first diagonal bar 4 is placed between the two columns of vertical bars 62, with the first connecting blocks 12 at both ends of the first diagonal bar 4 resting on the discs 1 at different heights of the two vertical bars 62. Then, the first baffle plate 18 is pressed against the arc plate 20.

[0068] After the horizontal bar 61, the first inclined bar 4, and the second inclined bar 5 are placed, the drive sleeve 111 is rotated upwards. The drive sleeve 111 drives each drive plate 112 below the disc 1 to rotate away from the vertical bar 62 via the push block 23, thereby driving the pressure plate 10 to rotate towards the vertical bar 62. After one pressure plate 10 on the disc 1 is pressed, the drive sleeve 111 is stopped. Then, each screw 31 on the drive sleeve 111 is rotated. By rotating the screw 31, the push block 23 is adjusted to rise and fall, thereby facilitating the rotation of a single pressure plate 10, so that each pressure plate 10 on the disc 1 correspondingly presses against the inner wall of the first pressure port 15, the inner wall of the second pressure port 16, and the inner wall of the third pressure port 17.

[0069] When each horizontal bar 61, vertical bar 62, first diagonal bar 4 and second diagonal bar 5 are connected to each other, the pressure plate 10 is rotated and pressed to reduce the vibration of the support frame 6, thereby facilitating the connection of the horizontal bar 61 and vertical bar 62 to form the support frame 6.

[0070] After each horizontal bar 61, vertical bar 62, first diagonal bar 4, and second diagonal bar 5 are connected to each other, the support plate 30 is inserted into the top of the vertical bar 62 via the screw 31. Then, the template 29 is placed on each support plate 30, and then the drive ring 32 is rotated. The drive ring 32 drives the screw 31 to rotate and rise, thereby adjusting the height of the template 29. Adjusting the height of the template 29 seals the pre-reserved pouring opening in the ceiling.

[0071] Construction workers pour concrete into the pouring port, and after the concrete solidifies, it forms a post-pouring strip. After the post-pouring strip is poured, the drive ring 32 is rotated to lower the support plate 30. Then, the formwork 29 is removed from the post-pouring strip. Afterward, the drive sleeve 111 is rotated to move downward, thereby loosening the pressure plate 10. After the pressure plate 10 is loosened, the horizontal bar 61, vertical bar 62, first diagonal bar 4, and second diagonal bar 5 are removed, thus facilitating the implementation of the post-pouring strip support structure for the recovery pump.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
