Description

Technical Field

[0001] This application relates to the technical field of post-cast strip steel pipe column support, and in particular to a post-cast strip steel pipe column support device. Background Technology

[0002] A post-cast strip is a concrete strip left at the corresponding position of the foundation slab, wall, or beam during the construction process to prevent harmful cracks caused by uneven shrinkage or settlement of the reinforced concrete structure, in accordance with design or construction specifications.

[0003] During the construction of the post-pouring strip, steel pipe columns are usually pre-installed under the beam to maintain the stability of the beam and slab. First, the original support system at the post-pouring strip is erected using ordinary scaffolding steel pipe supports. Then, holes are cut in the bottom formwork of the beam 150-140mm away from the edge of the post-pouring strip. The steel pipe columns are then placed at the opening under the beam. The upper end of the steel pipe columns is fixed to the beam and slab with iron nails. The lower part of the steel pipe columns is supported by short wooden blocks to the corresponding position. Finally, concrete blocks are poured at the bottom of the steel pipe columns for fixation.

[0004] However, in actual construction, it was found that when adjusting the height of the steel pipe column using short wooden blocks, it was not only difficult to control the distance the steel pipe column rose and to correct its verticality, but also that the concrete blocks at the bottom of the steel pipe column had to be smashed before dismantling it, which was labor-intensive. Summary of the Invention

[0005] To facilitate the loading, unloading, and height adjustment of steel pipe columns, this application provides a support device for post-cast strip steel pipe columns.

[0006] The technical solution for the post-cast strip steel pipe column support device provided in this application is as follows:

[0007] A post-cast strip steel pipe column support device includes a support block with a receiving cavity for accommodating the steel pipe column. A support plate is slidably connected to the support block and is slidably disposed in the receiving cavity. The end of the steel pipe column located in the receiving cavity away from the beam plate is attached to the support plate. The support block is provided with a sliding component for driving the support plate to slide, and the support plate is also provided with a fixing component for fixing the steel pipe column.

[0008] By adopting the above technical solution, after the steel pipe column is embedded in the receiving cavity, the end of the steel pipe column away from the beam plate is attached to the support plate. When the support plate is slid by the sliding component, the steel pipe column can be moved towards the beam plate until it is embedded in the opening on the beam plate. This allows the steel pipe column to be fixed to the beam plate with steel nails, which facilitates the adjustment of the height of the steel pipe column and ensures the verticality of the steel pipe column during the sliding process, thus facilitating the installation of the steel pipe column to a certain extent. With the setting of the fixing component, the steel pipe column can remain attached to the support plate during the sliding process of the support plate, further facilitating the installation of the steel pipe column.

[0009] Preferably, the sliding assembly includes multiple sliding screws disposed on the support block, the outer wall of the support plate is provided with sliding blocks corresponding to the sliding screws, the inner wall of the receiving cavity is provided with a sliding groove for the sliding blocks to slide, the sliding screws are rotatably disposed in the sliding grooves, and the sliding blocks are provided with sliding threaded holes that cooperate with the sliding screws.

[0010] One end of any of the sliding screws away from the opening of the receiving cavity is coaxially provided with a sliding gear. The support block is provided with an operating through hole that communicates with the outside. Part of the sliding gear is located in the operating through hole. The sliding assembly also includes a sliding belt that is slidably connected to the support block. Adjacent sliding screws are connected by the sliding belt.

[0011] By adopting the above technical solution, with the cooperation of the sliding block and the sliding screw, when the sliding screw rotates, the sliding block can drive the support plate to slide along the length direction of the receiving cavity under the action of thread transmission. In this process, the sliding block can cooperate with the sliding groove to improve the stability of the support plate sliding. When the sliding gear is rotated, it can not only drive the sliding screw fixed with it to rotate, but also drive the other sliding screws to rotate synchronously under the action of belt transmission. Only the thread direction of the sliding screw needs to be adjusted adaptively, and the support plate can be driven to slide by the rotation of the sliding screw, which is convenient for adjusting the height of the steel pipe column.

[0012] Preferably, a locking block is slidably connected to the support block, and a locking groove is provided on the support block for the locking block to slide. After the locking block slides toward the sliding gear, it can be embedded between two teeth of the sliding gear.

[0013] By adopting the above technical solution, the rotation of the sliding gear is locked by setting the locking block, thereby locking the sliding of the support plate and improving the reliability of controlling the sliding of the support plate by the rotation of the sliding gear.

[0014] Preferably, the fixing component includes a plurality of pressing blocks disposed on the support plate, a clamping block slidably connected to the pressing block, a clamping groove for the clamping block to slide on the pressing block, a clamping elastic element for pushing the clamping block to slide toward the axis of the support plate, and a control element for controlling the clamping block to slide away from the axis of the support plate.

[0015] By adopting the above technical solution, the clamping block slides towards the axis of the support plate under the action of the clamping spring until it fits against the steel pipe column. The clamping block and the clamping spring work together to limit the steel pipe column, making it difficult for the steel pipe column to detach from the support plate. By setting the control components, the clamping block can slide away from the axis of the support plate. Therefore, during the process of the steel pipe column being embedded into the receiving cavity, the clamping block is less likely to restrict the steel pipe column from sliding to fit against the support plate, which facilitates the installation of the steel pipe column.

[0016] Preferably, the fixing assembly further includes an upper pressure block that is slidably connected to the lower pressure block. The upper pressure block is provided with a control post, and the lower pressure block is provided with a control groove for the control post to slide. The lower pressure block is provided with a control elastic element for driving the upper pressure block to slide toward the lower pressure block. After the upper pressure block slides, it abuts against the clamping block. The lower pressure block is provided with a mating element for driving the upper pressure block to slide away from the lower pressure block.

[0017] By adopting the above technical solution, the upper pressure block can slide down to abut against the clamping block under the action of the control elastic element, thereby increasing the pressure between the clamping block and the lower pressure block. Under the action of pressure, the clamping block is less likely to slide relative to the lower pressure block, thereby locking the sliding of the clamping block and improving the reliability of fixing the steel pipe column by the clamping block; by setting the mating parts, the locking of the upper pressure block on the sliding of the clamping block can be released.

[0018] Preferably, the mating component includes a connecting block that is slidably connected to the lower pressure block. The lower pressure block has a connecting groove for the connecting block to slide. The connecting groove is connected to the control groove. The connecting block has a push block. When the connecting block slides toward the upper pressure block, it can push the control column to slide out of the control groove through the push block. The lower pressure block has a restoring elastic element for driving the connecting block to slide out of the connecting groove.

[0019] The inner wall of the receiving cavity is provided with a mating block corresponding to the connecting groove. When the support plate slides to fit against the bottom wall of the receiving cavity, the mating block is embedded in the connecting groove and pushes the connecting block to slide towards the upper pressure block.

[0020] By adopting the above technical solution, during the installation of the steel pipe column, in order to facilitate the adjustment of the height of the steel pipe column, the support plate needs to be slid to fit against the bottom wall of the receiving cavity. When the support plate is slid to fit against the bottom wall of the receiving cavity, the mating block can be embedded in the connecting groove and push the connecting block to slide towards the upper pressure block. At this time, the push block can push the control column to slide out of the control groove, thereby separating the upper pressure block from the lower pressure block and releasing the upper pressure block from locking the clamping block to slide. Through the setting of the restoring elastic element, when the support plate slides to the point where the mating block separates from the connecting groove, the connecting block can be restored under the action of the restoring elastic element, and the upper pressure block can slide down to abut against the clamping block under the action of the control elastic element.

[0021] Preferably, the lower pressing block is provided with a buckle, the upper pressing block is provided with a fastening block that cooperates with the buckle, and the lower pressing block is provided with a rotating rod for driving the buckle to rotate, the rotating rod being rotatably connected to the lower pressing block;

[0022] A locking gear is coaxially provided on the rotating rod, and a locking rack that meshes with the locking gear is provided on the connecting block. When the connecting block slides toward the upper pressure block, the buckle can rotate to separate from the buckling block. When the connecting block slides toward the outside of the connecting groove, the buckle can rotate to the buckling block being embedded in the buckle.

[0023] By adopting the above technical solution, the length of the push block is limited so that when the connecting block slides towards the upper pressure block, the retaining ring can rotate to separate from the retaining block under the cooperation of the locking gear and the locking rack. At this time, the push block is in contact with the control post. If the connecting block continues to slide, the push block can push the upper pressure block to slide to separate from the lower pressure block. When the connecting block slides towards the outside of the connecting groove under the action of the restoring elastic element, the connecting block first slides to the point where the push block separates from the control post. After the upper pressure block is pressed against the lower pressure block under the action of the control spring, the connecting block continues to slide. The retaining ring can rotate to the point where the retaining block is embedded in the retaining ring under the cooperation of the locking gear and the locking rack. This makes it difficult for the upper pressure block to separate from the lower pressure block during the sliding process of the support plate, thus improving the reliability of locking the sliding of the clamping block under the cooperation of the upper and lower pressure blocks.

[0024] Preferably, the end of the mating block facing the pressing block is arranged in an arc shape.

[0025] By adopting the above technical solution, the end of the mating block facing the lower pressing block is set in an arc shape, which makes it easier for the support plate to slide into the mating block and embed into the connecting groove.

[0026] Preferably, the control component includes a control ring disposed at one end of the clamping block away from the axis of the support plate, and a control through hole communicating with the receiving cavity is provided through the support block. When the support plate slides to fit against the bottom wall of the receiving cavity, the control through hole communicates with the clamping groove.

[0027] The support block is equipped with an operating hook and a control hook. The control hook is rotatably connected to the outer wall of the support block. When the operating hook is inserted into the control through hole, it can drive the clamping block to slide away from the axis of the support plate under the cooperation of the operating hook and the control ring. After the control hook is rotated, it can be embedded in the control ring and cooperate with the control ring to restrict the sliding of the clamping block.

[0028] By adopting the above technical solution, after the support plate is slid to fit against the bottom wall of the receiving cavity, the operating hook can be inserted into the control through hole and embedded in the control ring. In this way, the clamping block can be driven to slide away from the axis of the support plate under the cooperation of the operating hook and the control ring. When the clamping block slides to the point where the control ring is outside the control through hole, the control hook can be rotated to be embedded in the control ring. Under the cooperation of the control hook and the control ring, the sliding of the clamping block towards the axis of the support plate is restricted, thereby facilitating the control of the steel pipe column being embedded in the receiving cavity.

[0029] Preferably, a fixing block is provided at one end of the support block near the opening of the receiving cavity. A fixing through hole for the steel pipe column to pass through is provided on the fixing block. An elastic fixing layer is provided on the inner wall of the fixing through hole. The fixing layer is in contact with the outer wall of the steel pipe column.

[0030] The fixing block includes a first fixing block and a second fixing block, which are arranged opposite to each other. Both the first fixing block and the second fixing block are rotatably connected to the support block. After rotation, the first fixing block and the second fixing block fit together or separate. A fitting ring is rotatably connected to the first fixing block, and a fitting block that cooperates with the fitting ring is provided on the second fixing block.

[0031] By adopting the above technical solution, the fixing block is divided into a first fixing block and a second fixing block. During the process of embedding the steel pipe column into the receiving cavity, the first fixing block and the second fixing block can be separated first to facilitate the embedding of the steel pipe column into the receiving cavity. When the first fixing block and the second fixing block are rotated to fit together, the fitting ring can rotate to the point where the fitting block is embedded in the fitting ring, so that the first fixing block and the second fixing block are fixed and the fixing layer is in contact with the outer wall of the steel pipe column, further fixing the steel pipe column and improving the reliability of fixing the steel pipe column by the support block.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. After the steel pipe column is embedded into the receiving cavity, the end of the steel pipe column away from the beam plate is attached to the support plate. When the support plate is slid by the sliding component, the steel pipe column can be moved towards the beam plate and into the opening on the beam plate. This allows the steel pipe column to be fixed to the beam plate with steel nails, which facilitates the adjustment of the height of the steel pipe column and ensures the verticality of the steel pipe column during the sliding process, which facilitates the installation of the steel pipe column to a certain extent.

[0034] 2. When the sliding gear is rotated, it can not only drive the sliding screw fixed to it to rotate, but also drive the other sliding screws to rotate synchronously under the action of belt drive. Only the thread direction of the sliding screw needs to be adjusted to adapt to the situation, so that the support plate can be moved by the rotation of the sliding screw, which makes it easy to adjust the height of the steel pipe column.

[0042] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0043] This application discloses a post-cast strip steel pipe column support device, referring to... Figure 1 and Figure 2 The system includes a support block 1 with a cavity 11 for accommodating a steel pipe column 2. A mounting plate 12 is welded to one end of the support block 1 away from the opening of the cavity 11. The mounting plate 12 is fixed to the ground by welding or expansion bolts 121. In this embodiment, the mounting plate 12 is fixed to the ground by expansion bolts 121, thus fixing the support block 1 to the ground. A support plate 13 is slidably connected to the support block 1. The outer diameter of the support plate 13 is the same as the inner diameter of the cavity 11. The support plate 13 slides along the length of the cavity 11. The end of the steel pipe column 2 located in the cavity 11 away from the beam 3 is attached to the support plate 13. Through the sliding of the support plate 13, the steel pipe column 2 can be moved to the opening on the beam 3, allowing the steel pipe column 2 to be fixed to the beam 3 by steel nails. This facilitates adjusting the height of the steel pipe column 2 and ensures its verticality during sliding, thus facilitating the installation of the steel pipe column 2 to a certain extent.

[0044] Reference Figure 3 and Figure 4 The support block 1 is provided with a sliding assembly for driving the support plate 13 to slide. The sliding assembly includes four sliding screws 14 that are rotatably connected to the support block 1. The sliding screws 14 are arranged in a circular array with the axis of the receiving cavity 11 as the center. The sliding screws 14 are arranged along the length of the receiving cavity 11 and rotate about their own axis as the axis of rotation. Four sliding blocks 131 corresponding to the sliding screws 14 are integrally formed on the outer wall of the support plate 13. The four sliding blocks 131 are arranged in a circular array with the axis of the support plate 13 as the center. The inner wall of the receiving cavity 11 is provided with a sliding groove 132 for the sliding blocks 131 to slide. The sliding screws 14 are rotatably disposed in the sliding groove 132. The sliding block 131 is provided with a sliding threaded hole 133 that cooperates with the sliding screw 14.

[0045] Reference Figure 1 , Figure 3 and Figure 4One of the sliding screws 14 has a sliding gear 141 coaxially fixed at one end away from the opening of the receiving cavity 11. The support block 1 has an operation through hole 15 communicating with the outside. The operation through hole 15 is located below the receiving cavity 11. Part of the sliding gear 141 is located in the operation through hole 15. The sliding assembly also includes four sliding belts 142 that are slidably connected to the support block 1. Adjacent sliding screws 14 are connected by sliding belts 142. When one sliding screw 14 rotates, the other sliding screws 14 can rotate under the action of belt drive. The thread direction of the sliding screw 14 is adaptively adjusted so that the support plate 13 can slide along the length direction of the receiving cavity 11 under the action of thread drive, which facilitates the control of the sliding of the support plate 13. With the cooperation of the sliding block 131 and the sliding groove 132, the stability of the sliding of the support plate 13 is improved.

[0046] Reference Figure 3 A locking block 17 is slidably connected to the support block 1. The locking block 17 slides along the length of the support block 1. The support block 1 has a locking groove 171 for the locking block 17 to slide. The locking block 17 engages with the teeth of the sliding gear 141. After the locking block 17 slides toward the sliding gear 141, it can be embedded between the two teeth of the sliding gear 141. The setting of the locking block 17 locks the rotation of the sliding gear 141, thereby locking the sliding of the support plate 13 and improving the reliability of controlling the sliding of the support plate 13 by the rotation of the sliding gear 141.

[0047] Reference Figure 3 , Figure 4 and Figure 5The support plate 13 is also provided with a fixing assembly for fixing the steel pipe column 2. The fixing assembly includes four pressing blocks 4 set on the support plate 13. The pressing blocks 4 are fixed to the outer wall of the support plate 13. The inner wall of the receiving cavity 11 is provided with a pressing block groove 18 for the pressing blocks 4 to slide. The four pressing blocks 4 are arranged in a circular array with the axis of the support plate 13 as the center. The four pressing blocks 4 and four sliding blocks 131 are staggered. A clamping block 41 is slidably connected to the pressing block 4. The pressing block 4 slides along the radial direction of the support plate 13. The pressing block 4 is provided with a clamping groove 411 for the clamping block 41 to slide. A limiting rod 42 is fixedly provided at one end of the clamping block 41 away from the axis of the support plate 13. A limiting plate 43 is fixedly provided on the inner wall of the clamping groove 411. A limiting through hole 431 for the limiting rod 42 to slide is provided through the limiting plate 43. The inner diameter of the limiting through hole 431 is the same as the outer diameter of the limiting rod 42. A limiting block 421 is fixedly provided coaxially at one end of the limiting rod 42 away from the clamping block 41. The outer diameter of the limiting block 421 is larger than the outer diameter of the limiting rod 42. After the clamping block 41 slides toward the axis of the support plate 13, the limiting block 421 and the end face of the limiting plate 43 away from the clamping block 41 are in contact. With the cooperation of the limiting rod 42, the limiting plate 43 and the limiting block 421, the sliding distance of the clamping block 41 is limited, and the stability of the sliding of the clamping block 41 is improved.

[0048] Reference Figure 5 The lower pressure block 4 is provided with a clamping elastic element for pushing the clamping block 41 to slide toward the axis of the support plate 13. In this embodiment, the clamping elastic element is a clamping spring 422. The clamping spring 422 is sleeved on the limiting rod 42 and is located between the clamping block 41 and the limiting plate 43. One end of the clamping spring 422 abuts against the clamping block 41, and the other end of the clamping spring 422 abuts against the end face of the limiting plate 43. By setting the clamping spring 422, the reliability of fixing the steel pipe column 2 located in the receiving cavity 11 by the clamping block 41 is improved. The end face of the clamping block 41 that is in contact with the steel pipe column 2 is set in an arc shape, and a wear-increasing layer is fixed on the end face of the clamping block 41 that is in contact with the steel pipe column 2. This not only increases the contact area between the clamping block 41 and the steel pipe column 2, but also increases the friction between the clamping block 41 and the steel pipe column 2, thereby improving the reliability of fixing the steel pipe column 2 by the cooperation of the clamping block 41.

[0049] Reference Figure 5The lower pressure block 4 is equipped with a control component that controls the clamping block 41 to slide away from the axis of the support plate 13. The control component includes a control ring 44 fixed to one end of the limiting block 421 away from the limiting rod 42. The support block 1 has a through-hole 19 for communicating with the receiving cavity 11. When the support plate 13 slides to fit against the bottom wall of the receiving cavity 11, the control through-hole 19 communicates with the clamping groove 411. A control hook 191 is rotatably connected to the outer wall of the support block 1. The support block 1 is also equipped with an operating... In actual operation, the operating hook can first be inserted into the control through hole 19 and then embedded in the control ring 44. In this way, the clamping block 41 can be moved away from the axis of the support plate 13 by the cooperation of the operating hook and the control ring 44. When the clamping block 41 slides to the point where the control ring 44 is outside the control through hole 19, the control hook 191 can be rotated to be embedded in the control ring 44. With the cooperation of the control hook 191 and the control ring 44, the sliding of the clamping block 41 towards the axis of the support plate 13 is restricted.

[0050] Before the steel pipe column 2 is inserted into the receiving cavity 11, the sliding of the clamping block 41 toward the axis of the support plate 13 is restricted by the cooperation of the control hook 191 and the control ring 44. After the steel pipe column 2 is inserted into the receiving cavity 11, the restriction on the sliding of the clamping block 41 is released, so that the clamping block 41 can slide down to abut against the outer wall of the steel pipe column 2 under the action of the clamping spring 422, thereby facilitating the fixing of the steel pipe column 2 and the installation of the steel pipe column 2.

[0051] Reference Figure 5 and Figure 6 The fixing assembly also includes an upper pressure block 5 that is slidably connected to the lower pressure block 4. The upper pressure block 5 is located above the lower pressure block 4 and is slidably disposed in the pressure block groove 18. The upper pressure block 5 has a fitting groove 51 for the clamping block 41 to be inserted. A friction-enhancing layer is fixed on the inner wall of the fitting groove 51. Control posts 52 are provided on both sides of the fitting groove 51. The control posts 52 are fixed to the upper pressure block 5 and are arranged along the length direction of the pressure block groove 18. The lower pressure block 4 has a control groove 45 for the control posts 52 to slide. The lower pressure block 4 is provided with a control elastic element for driving the upper pressure block 5 to slide toward the lower pressure block 4. In this embodiment, the control elastic element is a control spring 521. The control spring 521 is sleeved on the control column 52. Both ends of the control spring 521 are fixed to the inner wall of the control groove 45. The upper pressure block 5 can slide toward the lower pressure block 4 under the action of the control spring 521, so that the clamping block 41 is pressed against the inner wall of the fitting groove 51 and the clamping groove 411. This makes it difficult for the clamping block 41 to slide along the clamping groove 411 during the sliding process of the support plate 13, thereby improving the reliability of fixing the steel pipe column 2 by the clamping block 41.

[0052] Reference Figure 5 and Figure 6The lower pressure block 4 is provided with a fitting component for driving the upper pressure block 5 to slide away from the lower pressure block 4. The fitting component includes a connecting block 46 that is slidably connected to the lower pressure block 4. The lower pressure block 4 is provided with a connecting groove 461 for the connecting block 46 to slide. The connecting block 46 slides along the length of the control groove 45 and the connecting groove 461 communicates with the control groove 45. A push block 462 is fixed at one end of the connecting block 46 facing the control column 52. When the connecting block 46 slides towards the upper pressure block 5, it can push the control column 52 to slide outward from the control groove 45 through the push block 462. The inner wall of the receiving cavity 11 is provided with a mating block 111 corresponding to the connecting groove 461. When the support plate 13 slides to fit against the bottom wall of the receiving cavity 11, the mating block 111 is embedded in the connecting groove 461 and pushes the connecting block 46 to slide towards the upper pressure block 5, so that the upper pressure block 5 and the lower pressure block 4 are separated. The end of the mating block 111 facing the lower pressure block 4 is set in an arc shape, so that the support plate 13 can slide into the mating block 111 embedded in the connecting groove 461.

[0053] Reference Figure 6 The lower pressure block 4 is provided with a restoring elastic element for driving the connecting block 46 to slide outward toward the connecting groove 461. In this embodiment, the restoring elastic element is a restoring spring 463. One end of the restoring spring 463 is fixed to the inner wall of the connecting groove 461, and the other end of the restoring spring 463 is fixed to the connecting block 46. With the setting of the restoring spring 463, when the support plate 13 slides away from the bottom wall of the receiving cavity 11, the connecting block 46 can be reset under the action of the restoring spring 463.

[0054] Reference Figure 5 and Figure 6 The lower pressing block 4 is provided with a retaining ring 47, and the upper pressing block 5 is provided with a retaining block 53 that cooperates with the retaining ring 47. The end of the retaining block 53 facing away from the upper pressing block 5 is arc-shaped, so that the retaining ring 47 can rotate until the retaining block 53 is embedded in the retaining ring 47. The lower pressing block 4 is rotatably connected with a rotating rod for driving the retaining ring 47 to rotate. When the rotating rod rotates, it can drive the retaining ring 47 to rotate. A locking gear 471 is coaxially fixed on the rotating rod, and a locking rack 464 that meshes with the locking gear 471 is fixed on the connecting block 46.

[0055] The length of the push block 462 is limited so that when the connecting block 46 slides toward the upper pressure block 5, the retaining ring 47 can rotate to separate from the retaining block 53 under the cooperation of the locking gear 471 and the locking rack 464. At this time, the push block 462 is in contact with the control post 52. If the connecting block 46 continues to slide, the push block 462 can push the upper pressure block 5 to slide to separate from the lower pressure block 4. When the connecting block 46 slides toward the outside of the connecting groove 461 under the action of the return spring 463, the connecting block... 46 first slides until the push block 462 separates from the control column 52. After the upper pressure block 5 is pressed against the lower pressure block 4 under the action of the control spring 521, the connecting block 46 continues to slide. The retaining ring 47 can rotate until the retaining block 53 is embedded in the retaining ring 47 under the cooperation of the locking gear 471 and the locking rack 464. This makes it difficult for the upper pressure block 5 to separate from the lower pressure block 4 during the sliding process of the support plate 13, thus improving the reliability of the locking clamping block 41 sliding under the cooperation of the upper pressure block 5 and the lower pressure block 4.

[0056] Reference Figure 1 , Figure 2 and Figure 3 A fixing block 6 is provided at one end of the support block 1 near the opening of the receiving cavity 11. A fixing through hole 63 for the steel pipe column 2 to pass through is provided on the fixing block 6. An elastic fixing layer 631 is provided on the inner wall of the fixing through hole 63. The fixing layer 631 fits against the outer wall of the steel pipe column 2. With the cooperation of the fixing block 6 and the fixing layer 631, the steel pipe column 2 is further fixed, which improves the reliability of fixing the steel pipe column 2 by the support block 1 instead of the concrete block.

[0057] Reference Figure 1 , Figure 2 and Figure 3 The fixing block 6 includes a first fixing block 61 and a second fixing block 62, which are arranged opposite to each other. Both the first fixing block 61 and the second fixing block 62 are rotatably connected to the support block 1. In this embodiment, the first fixing block 61 and the second fixing block 62 are rotatably connected to the support block 1 via hinges. After rotation, the first fixing block 61 and the second fixing block 62 can fit together or separate. A fitting ring 611 is rotatably connected to the first fixing block 61, and a fitting block 621 that cooperates with the fitting ring 611 is provided on the second fixing block 62. When the first fixing block 61 and the second fixing block 62 rotate to fit together, the fitting ring 611 can rotate until the fitting block 621 is embedded in the fitting ring 611, thereby fixing the first fixing block 61 and the second fixing block 62. By dividing the fixing block 6 into the first fixing block 61 and the second fixing block 62, the first fixing block 61 and the second fixing block 62 can be separated first during the process of embedding the steel pipe column 2 into the receiving cavity 11, which facilitates the embedding of the steel pipe column 2 into the receiving cavity 11.

[0058] The implementation principle of the post-cast strip steel pipe column support device in this application embodiment is as follows: When installing the steel pipe column 2, first release the lock between the first fixed block 61 and the second fixed block 62, so that the first fixed block 61 and the second fixed block 62 are separated. Insert the operating hook into the control through hole 19, and with the cooperation of the operating hook and the control ring 44, drive the clamping block 41 to slide in a direction away from the axis of the support plate 13. When the clamping block 41 slides to the point that the control ring 44 is outside the control through hole 19, rotate the control hook 191 to be embedded in the control ring 44.

[0059] Then, the steel pipe column 2 is embedded in the receiving cavity 11 and moved to the opening under the beam plate 3. At this time, the support plate 13 is in contact with the bottom wall of the receiving cavity 11 and the mating block 111 is located in the mating groove. The steel pipe column 2 embedded in the receiving cavity 11 is in contact with the support plate 13. The control hook 191 is released from locking the control ring 44, so that the clamping block 41 can slide down to be in contact with the outer wall of the steel pipe column 2 under the action of the clamping spring 422. The locking block 17 is slid to separate from the sliding gear 141. The sliding gear 141 is rotated so that the support plate 13 drives the steel pipe column 2 to slide to the opening on the beam plate 3. During this process, the mating block 111 is separated from the connecting block 46. The connecting block 46 slides outward toward the connecting groove 461 under the action of the restoring spring 463. The upper pressure block 5 slides to be pressed against the lower pressure block 4 and the buckle 47 rotates until the buckle block 53 is embedded in the buckle 47.

[0060] Finally, the first fixed block 61 and the second fixed block 62 are rotated until they fit together, and the fitting ring 611 is rotated until the fitting block 621 is embedded in the fitting ring 611, so that the first fixed block 61 and the second fixed block 62 are fixed. The support block 1 is fixed to the ground by the expansion bolt 121, and the installation of the steel pipe column 2 is completed.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
