Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a prefabricated post-pouring strip temporary protection device. Background Technology
[0002] Post-cast strips are temporary construction joints reserved in buildings to address settlement and temperature deformation. The reservation period can range from several days to several months (for example, post-cast strips for settlement need to be poured after the structure has settled and stabilized). During this period, the post-cast strip is not enclosed by any structure, which can easily lead to problems such as debris accumulation, steel corrosion, component displacement, grout leakage, and personnel falling. Temporary protection of post-cast strips is a protective measure set up for this "window period".
[0003] Traditionally, plywood is often used to seal and protect post-cast strips. However, plywood itself has low structural strength and poor load-bearing capacity. It is easily damaged by construction workers during construction and cannot play a stable protective role in the long term. The safety protection effect is not good. At the same time, the installation and dismantling of plywood is cumbersome and consumes a lot of manpower and resources. Plywood is also prone to moisture and damage, and it is difficult to repair after damage and is not easy to reuse.
[0004] Therefore, in view of the above situation, there is an urgent need to develop a prefabricated temporary protection device for post-pouring strips to overcome the shortcomings in current practical applications. Summary of the Invention
[0005] The purpose of this invention is to provide a prefabricated temporary protection device for post-pouring strips, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A prefabricated temporary protection device for post-pouring strips includes an anti-slip steel plate, a flap, square steel, and back ribs. The anti-slip steel plate has flaps rotatably connected to both sides. Square steel is fixedly connected to both sides of the bottom of the anti-slip steel plate. Multiple back ribs are fixedly connected between two square steels. Support blocks two and three are fixedly connected to the back ribs on both sides. Support block one is also fixedly connected to one of the back ribs. An insert rod is slidably connected inside support block one. A first driving component is fitted onto the insert rod. A cylinder is slidably connected to the inner wall of support block three. The cylinder has a smooth groove and a curved groove that communicate with each other. An inclined block is fixedly connected to the other end of the cylinder. The insert rod is slidably connected to the inner wall of the cylinder. A sliding head is fixedly connected to a section of the insert rod near the inclined block, and the sliding head abuts against the inner wall of the smooth groove or curved groove. A second driving component is fitted onto the outer wall of the cylinder. When the sliding head slides against the inner wall of the curved groove, the inclined block rotates around the axis of the insert rod.
[0007] A further technical solution includes a fixed block fixedly connected to the lower end of the insert rod, and a symmetrical rotating plate rotatably connected to the fixed block. When the rotating plate is perpendicular to the axis of the insert rod, the side wall of the rotating plate abuts against one end of the insert cylinder, and at this time the slider is located at the bottom end of the inner wall of the second drive assembly. A fixed frame symmetrical about the insert rod is fixedly connected to the lower end of one of the back ribs, and a slider is slidably connected to each of the fixed frames. An adjustment component is fitted on the slider, and the adjustment component is rotatably connected to the corresponding rotating plate. A transfer assembly is fitted on the side wall of the slider, and an abutment plate is fixedly connected to the transfer assembly. The abutment plate is used to abut against the inner wall of the post-pouring strip.
[0008] In a further technical solution, the trajectory of the curved slide groove is a spiral line, and less than half a turn. As long as the slide head is located in the curved slide groove, the inclined locking block can engage with the two end faces of the support block.
[0009] A further technical solution includes a T-shaped rod, a gear, an insert groove, and a rack. A T-shaped groove is formed on the anti-slip steel plate, and a T-shaped rod is rotatably connected within the T-shaped groove. A gear is fixedly connected to the bottom end of the T-shaped rod. An insert groove is formed on the insert rod, and a rack is fixedly connected within the insert groove, with the rack meshing with the gear. A mark 1 is provided on the T-shaped rod, and multiple mark 2s are provided on the anti-slip steel plate. The T-shaped rod and the anti-slip steel plate are used to mark the rotation angle of the T-shaped rod. The marks on the anti-slip steel plate correspond to the positions of the slider at the connection between the smooth groove and the curved groove, the bottom end of the curved groove, and the position where the inclined block retracts and coincides with the three end faces of the support block.
[0010] A further technical solution includes an adjustment groove, an adjustment block, and an adjustment screw; the slider has an adjustment groove, the adjustment screw is fixedly connected in the adjustment groove, the inner wall of the adjustment groove is also slidably connected to the adjustment block, the adjustment block is threadedly connected to the adjustment screw, the lower end of the adjustment block is rotatably connected to the rotating plate, and the lower end of the slider is also provided with a mark three for marking the position of the adjustment block, the mark three also corresponds to the distance between the abutment plate and the axis when the rotating plate is perpendicular to the insertion rod.
[0011] A further technical solution is provided, wherein the transfer assembly includes a mating groove, a fixing rod, a connecting block, and a spring; a mating groove is provided at the end of the slider away from the axis of the insertion rod, a fixing rod is fixedly connected to the inner wall of the mating groove, a connecting block is slidably connected to the inner wall of the mating groove, and the connecting block is slidably connected to the fixing rod, the connecting block is fixedly connected to the abutment plate, and a spring is provided between the connecting block and the inner wall of the mating groove at the end away from the support block.
[0012] In a further technical solution, the second driving component includes a support block four, a spring two, and a fixing ring; the support block four is fixedly connected to the bottom end of the anti-slip steel plate, the support block four is slidably connected to the outer wall of the insert, the outer wall of the insert is also fixedly connected to a fixing ring, and the spring two in a compressed state is also provided between the fixing ring and the support block four.
[0013] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art: 1. The anti-slip steel plate, flip plate, square steel, and back rib are all made of steel rigid structure, which greatly improves the structural strength and load-bearing capacity of the device, avoids deformation and dent of the plate surface, and ensures the sealing and protection effect of the post-pouring strip; the insertion rod slides and the abutment plate is aligned to form a linkage structure. Driving the insertion rod can simultaneously move the abutment plate close to the inner wall of the post-pouring strip, automatically adjust the posture of the device to achieve initial alignment, and eliminate the need for manual operation of the alignment step, reduce the difficulty of splicing and alignment, and improve on-site construction efficiency. The sliding head, smooth groove and curved groove work together to form a rotating snap-fit structure. The sliding rod can drive the inclined snap-fit block to rotate and snap-fit the support block of the adjacent device, realizing the mechanical locking of the splicing. The inclined snap-fit block adopts an inclined edge design, which can move slightly to the adjacent device during the rotation snap-fit process, automatically compensate for the splicing gap, realize seamless splicing, prevent slurry and debris from seeping into the post-pouring strip from the joint, and ensure the cleanliness of the subsequent poured base layer.
[0014] 2. The transfer assembly allows the anti-slip steel plate to make slight axial movements relative to the abutment plate, effectively compensating for the unevenness error of the inner wall of the post-pouring strip and avoiding the friction between the abutment plate and the inner wall of the post-pouring strip from hindering the splicing of the device. 3. The installation and disassembly of the device are completed by driving the insertion rod through the first drive component. No complicated tools are required throughout the process. The operation steps are simple and quick. When disassembling, the inclined locking block can be retracted into the support block three to avoid collision damage or scratches to construction personnel during transportation and disassembly, thereby improving operational safety. 4. The spacing between the two abutment plates can be precisely adjusted by rotating the adjusting screw, adapting to post-pouring strips of different widths. This eliminates the need for customizing multiple devices, greatly improving the versatility and adaptability of the device.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0019] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0020] like Figures 1-8As shown, this embodiment of the invention provides a prefabricated temporary protection device for post-pouring strips, including an anti-slip steel plate 1, a flap 2, square steel 3, and back ribs 4. The anti-slip steel plate 1 is rotatably connected to both sides of the flap 2. Square steel 3 is fixedly connected to both sides of the bottom end of the anti-slip steel plate 1. Multiple back ribs 4 are fixedly connected between two square steel 3. Support blocks 2 and 3 are fixedly connected to the back ribs 4 on both sides. One of the back ribs 4 is also fixedly connected to a support block 1 5. An insert rod 6 is slidably connected inside the support block 1 5. A first driving component 7 for driving the insert rod 6 to reciprocate is provided on the insert rod 6. An insert cylinder 17 is slidably connected to the inner wall of the support block 3 9. The insert cylinder 17 has a communicating smooth groove 20 and a curved groove. The other end of the insert 17 is fixedly connected to a slanted block 18. The slanted block 18 fixes two adjacent anti-slip steel plates 1 together by cooperating with the support block 2 8 of the adjacent anti-slip steel plate 1. The insert rod 6 is slidably connected to the inner wall of the insert 17. A slide head 19 is fixedly connected to a section of the side wall of the insert rod 6 near the slanted block 18. The slide head 19 abuts against the inner wall of the smooth groove 20 or the curved groove 22. A second drive assembly 21 is provided on the outer wall of the insert 17. The second drive assembly 21 is used to drive the insert 17 to slide along the inner wall of the support block 3 9 into the support block 2 8 on the adjacent anti-slip steel plate 1. When it is necessary to control the slanted block 18 to rotate around the axis of the insert rod 6, the slide head 19 abuts against the inner wall of the curved groove 22. A fixing block 13 is fixedly connected to the lower end of the insertion rod 6. A symmetrical rotating plate 14 is rotatably connected to the fixing block 13. When the rotating plate 14 is perpendicular to the axis of the insertion rod 6, the side wall of the rotating plate 14 abuts against one end of the insertion cylinder 17. At this time, the slider 19 is located at the bottom end of the inner wall of the second drive assembly 21. A fixing frame 10 symmetrical about the insertion rod 6 is fixedly connected to the lower end of one of the back ribs 4. A slider 11 is slidably connected to each fixing frame 10. An adjustment component 15 is provided on each slider 11. The adjustment component 15 is rotatably connected to the corresponding rotating plate 14. The rotating plate is adjusted by adjusting the adjustment component 15. The end of 14 away from the fixed block 13 is located on the slider 11. The slider 11 is fitted with a transfer assembly 16 on its side wall. An abutment plate 12 is fixedly connected to the transfer assembly 16. The abutment plate 12 is used to abut against the inner wall of the post-pouring strip. Before the adjacent anti-slip steel plates 1 are fixed together (i.e. before the inclined block 18 rotates around the axis of the insert rod 6) by the cooperation of the insert rod 6 and the rotating plate 14, the posture of the anti-slip steel plate 1 is adjusted so that it is initially aligned with the post-pouring strip. The transfer assembly 16 avoids the friction between the abutment plate 12 and the inner wall of the post-pouring strip from hindering the anti-slip steel plate 1 from moving closer to the adjacent one.
[0021] Specifically, the first drive assembly 7 drives the insert rod 6 to slide back and forth along the inner wall of the support block 5. When the insert rod 6 slides towards the support block 9 (i.e., when adjacent anti-slip steel plates 1 need to be spliced), the insert rod 6 drives the slider 19 to slide along the inner wall of the smooth groove 20. During this process, the insert rod 6 simultaneously drives the fixed block 13 to move. Then, the fixed block 13 drives the sliders 11 on both sides to slide away from the axis of the insert rod 6 through the rotating plate 14. The sliders 11 drive the abutment plate 12 to approach the inner wall of the post-pouring strip through the transfer assembly 16, thereby adjusting the posture of the anti-slip steel plate 1 and making it initially aligned until the slider 19 is located at the connection between the inner walls of the smooth groove 20 and the curved groove 22. The process involves moving the anti-slip steel plate 1 towards the adjacent anti-slip steel plate 1 until the inclined block 18 is inserted into the support block 2 8 on the adjacent post-cast strip. As the insert rod 6 continues to slide towards the support block 3 9, the slider 19 is engaged in the curved groove 22 and slides along the inner wall of the curved groove 22. During this process, the insert rod 6 continues to move the fixing block 13. The fixing block 13 drives the sliders 11 on both sides to continue sliding away from the axis of the insert rod 6 through the rotating plate 14. The sliders 11 drive the abutment plates 12 on both sides to continue moving through the transfer assembly 16 until the abutment plates 12 firmly abut against the inner wall of the post-cast strip, thereby firmly fixing the anti-slip steel plate 1 and effectively improving the stability of the anti-slip steel plate 1. Because the way the fixed frame 10, slider 11 and rotating plate 14 cooperate restrict the insertion rod 6 to move only along the axis, the slider 19 pushes the insertion cylinder 17 to rotate through the inner wall of the curved groove 22. The insertion cylinder 17 drives the inclined block 18 to rotate around the axis of the insertion cylinder 17. The inclined block 18 disengages from the groove of the support block 2 8 and abuts against its end face. At this time, the adjacent anti-slip steel plate 1 abuts and restricts the movement of the insertion rod 6, thereby fixing the two adjacent anti-slip steel plates 1 together. In addition, when the inclined block 18 is inserted into the support block 2 8 on the adjacent anti-slip steel plate 1, there may be a small gap between the adjacent anti-slip steel plates 1, which may cause the post-pouring strip to fail to close. Therefore, during the process of the insert 17 driving the inclined block 18 to rotate around the axis of the insert 17, the inclined edge of the inclined block 18 first contacts the inner wall of the groove of the support block 2 8, and then separates from the groove of the support block 2 8 and abuts against the end face of the support block 2 8. During this process, the inclined block 18 moves slightly towards the adjacent anti-slip steel plate 1, thereby closing the gap between the adjacent anti-slip steel plates 1. When the insert rod 6 slides away from the support block 9 (i.e., when the anti-slip steel plate 1 needs to be removed), the insert rod 6 drives the slide head 19 to move away from the support block 9. Then, the slide head 19 drives the insert cylinder 17 to rotate in the opposite direction through the curved slide groove 22. The insert cylinder 17 drives the inclined locking block 18 to rotate around the axis of the insert cylinder 17. When the slide head 19 is located at the connection between the smooth groove 20 and the curved slide groove 22, the inclined locking block 18 is aligned with the groove in the support block 9. Then, as the insert rod 6 continues to slide away from the support block 9, the insert rod 6 drives the slide head 19 to rotate in the opposite direction. The head 19 slides along the inner wall of the smooth groove 20 until the head 19 abuts against the inner wall of the smooth groove 20 at the end away from the support block 3 9. Then the insert rod 6 continues to slide away from the support block 3 9. The smooth groove 20 drives the insert cylinder 17 to slide and retract along the inner wall of the support block 3 9 towards the support block 1 5. The insert cylinder 17 simultaneously drives the inclined block 18 to move and retract into the support block 3 9, effectively preventing the inclined block 18 from colliding with personnel or other devices, thus protecting safety. After that, the anti-slip steel plate 1 can be removed from the post-pouring strip. The disassembly process is simple and quick. By adjusting the position of the end of the rotating plate 14 away from the fixed block 13 on the slider 11 through the adjusting component 15, the distance between the abutment plate 12 and the axis of the insert rod 6 can be adjusted, thereby accommodating post-pouring strips of different widths.
[0022] Understandably, the anti-slip steel plate 1, the flip plate 2, the square steel 3, and the back rib 4 are all made of steel and have high strength. The surface of the anti-slip steel plate 1 is covered with strip-shaped anti-slip protrusions, which can effectively increase the friction. Two square steels (60x60) are welded to both sides of the bottom and set on both sides of the post-pouring strip to form a rigid frame that can bear the construction load and keep the plate surface flat. The back rib 4 at the bottom of the anti-slip steel plate 1 can further enhance the overall load-bearing capacity. They are welded together with the anti-slip steel plate 1 and the square steel 3 to distribute and transfer the load and prevent the anti-slip steel plate 1 from deforming or denting under heavy load.
[0023] Furthermore, the trajectory of the curved slide groove 22 is a spiral line, and less than half a turn, ensuring that as long as the slide head 19 is located in the curved slide groove 22, the inclined locking block 18 can engage with the end face of the support block 2 8.
[0024] like Figure 1 , Figure 2 and Figure 4As shown, the first drive assembly 7 includes a T-shaped rod 71, a gear 72, an embedding groove 73, and a rack 74. A T-shaped groove (not marked in the figure) is provided on the anti-slip steel plate 1. The T-shaped rod 71 is rotatably connected within the T-shaped groove. The gear 72 is fixedly connected to the bottom end of the T-shaped rod 71. An embedding groove 73 is provided on the insert rod 6. A rack 74 is fixedly connected within the embedding groove 73, and the rack 74 meshes with the gear 72. Mark 1 is provided on the T-shaped rod 71, and multiple marks 2 are provided on the anti-slip steel plate 1. The way the T-shaped rod 71 and the anti-slip steel plate 1 cooperate is used to mark the rotation angle of the T-shaped rod 71. The marks on the anti-slip steel plate 1 correspond to the positions of the slider 19 at the connection between the smooth groove 20 and the curved groove 22, the bottom end of the curved groove 22, and the position where the inclined block 18 coincides with the end face of the support block 3 9 when it retracts.
[0025] It is understandable that the rotation angle range of the T-shaped rod 71 can be identified even if the first mark on the T-shaped rod 71 and the second mark on the anti-slip steel plate 1 do not coincide, thereby identifying the position of the slider 19 and the inclined block 18.
[0026] Specifically, a four-corner wrench is inserted into the groove on the upper surface of the T-shaped rod 71, which then rotates the T-shaped rod 71. The T-shaped rod 71 drives the gear 72 to rotate, the gear 72 drives the rack 74 to move, and the rack 74 drives the insert rod 6 to slide along the inner wall of the support block 5. The rotation angle of the T-shaped rod 71 is identified by the scale marks set on the T-shaped rod 71 and the anti-slip steel plate 1, thereby identifying the position of the slider 19 and the inclined block 18.
[0027] like Figure 2 , Figure 6 and Figure 8 As shown, the adjusting assembly 15 includes an adjusting groove 151, an adjusting block 152, and an adjusting screw 153. The slider 11 has an adjusting groove 151, and the adjusting screw 153 is fixedly connected in the adjusting groove 151. The adjusting block 152 is also slidably connected to the inner wall of the adjusting groove 151. The adjusting block 152 is threadedly connected to the adjusting screw 153. The lower end of the adjusting block 152 is rotatably connected to the rotating plate 14. The lower end of the slider 11 is also provided with a mark three (not marked in the figure) for marking the position of the adjusting block 152. The mark three also corresponds to the distance between the abutment plate 12 and the axis when the rotating plate 14 is perpendicular to the insertion rod 6.
[0028] Specifically, for post-cast strips of different widths, the distance between the abutment plate 12 and the axis of the insert rod 6 needs to be adjusted (adjusted outside the post-cast strip). First, drive the insert rod 6 to slide along the inner wall of the support block 5 until the rotating plate 14 abuts against the inner wall of one end of the insert cylinder 17 and the support block 9. At this time, the rotating plate 14 is perpendicular to the axis of the insert rod 6. Control the adjusting screw 153 to rotate. Then, the adjusting screw 153 drives the adjusting block 152 to slide along the inner wall of the adjusting groove 151. By marking the position of the three adjusting blocks 152, it is ensured that the positions of the adjusting blocks 152 on both sides are the same, and the distance between the abutment plate 12 and the axis when the rotating plate 14 is perpendicular to the insert rod 6 can be identified in real time, thereby identifying the distance between the two abutment plates 12, thus adapting to post-cast strips of different widths.
[0029] like Figure 3 , Figure 6 and Figure 8 As shown, the transfer assembly 16 includes a mating groove 161, a fixing rod 162, a connecting block 163, and a spring 164. The sliding block 11 has a mating groove 161 at one end away from the axis of the insertion rod 6. The fixing rod 162 is fixedly connected to the inner wall of the mating groove 161. The connecting block 163 is slidably connected to the inner wall of the mating groove 161, and the connecting block 163 is slidably connected to the fixing rod 162. The connecting block 163 is fixedly connected to the abutment plate 12. A spring 164 is provided between the connecting block 163 and the inner wall of the mating groove 161 at the end away from the support block 9.
[0030] Specifically, when the inclined clamping block 18 is inserted into the support block 2 8 on the adjacent post-cast strip, there may be a small gap between the adjacent anti-slip steel plates 1. The anti-slip steel plates 1 need to move slightly towards the adjacent anti-slip steel plates 1. That is, during the process of the inclined clamping block 18 disengaging from the groove of the support block 2 8 and abutting against the end face of the support block 2 8, the inclined clamping block 18 needs to move slightly towards the adjacent anti-slip steel plates 1. Since the inner wall of the post-cast strip may be uneven and may hinder the movement of the abutting plate 12, in order to avoid hindering the movement of the anti-slip steel plates 1, the anti-slip steel plates 1 can move relative to the abutting plate 12 in the direction of the axis of the insert rod 6. The anti-slip steel plates 1 move along the axis of the insert rod 6 towards the adjacent anti-slip steel plates 1 (i.e., towards the inclined clamping block). In the direction of 18, the adjacent anti-slip steel plate 1 is already fixed. Then, the anti-slip steel plate 1 drives the fixing frame 10 to move along the axis of the insertion rod 6. After that, the fixing frame 10 drives the slider 11 to move along the axis of the insertion rod 6. The slider 11 drives the fixing rod 162 to move. Since the abutment plate 12 is stationary, the connecting block 163 does not move in the direction of the axis of the insertion rod 6. The slider 11 compresses the fixing rod 162 through the inner wall of the mating groove 161. The fixing rod 162 ensures that the initial position of the connecting block 163 on the inner wall of the mating groove 161 is close to the inclined block 18, thereby ensuring that there is room for the slider 11 to move on the left side of the connecting block 163 (refer to the support block 2 8 in the figure).
[0031] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the second drive assembly 21 includes a support block 211, a spring 212, and a fixing ring 213; the support block 211 is fixedly connected to the bottom end of the anti-slip steel plate 1, the support block 211 is slidably connected to the outer wall of the insert 17, the fixing ring 213 is also fixedly connected to the outer wall of the insert 17, and the spring 212 in a compressed state is also provided between the fixing ring 213 and the support block 211.
[0032] Specifically, when it is necessary to remove the anti-slip steel plate 1 from the adjacent anti-slip steel plate 1 of the post-pouring strip, the insert rod 6 needs to drive the slide head 19 to move away from the support block 3 9. When the slide head 19 slides to the inner wall of the smooth groove 20 away from the support block 3 9 (refer to the support block 5 in the figure), as the slide head 19 continues to move, the slide head 19 drives the insert cylinder 17 to move, the insert cylinder 17 drives the fixing ring 213 to move, and the fixing ring 213 compresses the spring 212. When it is necessary to install the anti-slip steel plate 1 on the adjacent anti-slip steel plate 1, the insert rod 6 needs to drive the slider 19 to move towards the support block 3 9. During this process, the spring 212 pushes the fixing ring 213 to move towards the support block 3 9. The fixing ring 213 drives the insert cylinder 17 to move and extend until the fixing ring 213 abuts against the end face of the support block 3 9. At this time, the end of the insert cylinder 17 with the inclined locking block 18 is inserted into the support block 2 8 on the adjacent anti-slip steel plate 1.
[0033] Furthermore, when the fixing ring 213 abuts against the support block 3 9, the distance between the end faces of the inclined block 18 and the support block 3 9 that are close to each other is equal to the width of the support block 2 8 along the axis of the insertion rod 6. This ensures that when the fixing ring 213 abuts against the support block 3 9, the projection of the end face of the support block 2 8 on the adjacent anti-slip steel plate 1 that is close to the support block 1 5 is located on the inclined surface of the inclined block 18. This ensures that the inclined surface of the inclined block 18 can handle the situation where there is a small gap between the adjacent anti-slip steel plates 1, and can reliably connect the two adjacent anti-slip steel plates 1 together.
[0034] The working principle of this invention is as follows: When the anti-slip steel plate 1 needs to be installed, the first driving assembly 7 drives the insert rod 6 to slide towards the support block 9. The insert rod 6 drives the slider 19 to slide along the inner wall of the smooth groove 20. During this process, the insert rod 6 synchronously drives the fixing block 13 to move. Then, the fixing block 13 drives the sliders 11 on both sides to slide away from the axis of the insert rod 6 through the rotating plate 14. The sliders 11 drive the abutment plate 12 to approach the inner wall of the post-pouring strip through the transfer assembly 16, thereby adjusting the posture of the anti-slip steel plate 1 and making it initially aligned until the slider 19 is located at the junction of the inner walls of the smooth groove 20 and the curved groove 22. At the junction, the anti-slip steel plate 1 is manually moved closer to the adjacent anti-slip steel plate 1 until the inclined block 18 is moved and inserted into the support block 2 8 on the adjacent post-pouring strip. As the insert rod 6 continues to slide closer to the support block 3 9, the slide head 19 is inserted into the curved slide groove 22 and slides along the inner wall of the curved slide groove 22. During this process, the insert rod 6 continues to move the fixed block 13. The fixed block 13 drives the sliders 11 on both sides to continue sliding away from the axis of the insert rod 6 through the rotating plate 14. The sliders 11 drive the abutment plates 12 on both sides to continue moving through the transfer assembly 16 until the abutment plates 12 firmly abut against the inner wall of the post-pouring strip. Because the way the fixed frame 10, slider 11 and rotating plate 14 cooperate restrict the insertion rod 6 to move only along the axis, when the slider 19 pushes the insertion cylinder 17 to rotate through the inner wall of the curved groove 22, the insertion cylinder 17 drives the inclined block 18 to rotate around the axis of the insertion cylinder 17. The inclined block 18 disengages from the groove of the support block 28 and abuts against the end face of the support block 28. At this time, the adjacent anti-slip steel plate 1 abuts and restricts the movement of the insertion rod 6, thereby fixing the two adjacent anti-slip steel plates 1 together. When it is necessary to remove the anti-slip steel plate 1 from the adjacent anti-slip steel plate 1 of the post-cast strip, the first drive assembly 7 drives the insert rod 6 to slide away from the support block 9. The insert rod 6 drives the slide head 19 to move away from the support block 9. Then, the slide head 19 drives the insert cylinder 17 to rotate in the opposite direction through the curved slide groove 22. The insert cylinder 17 drives the inclined locking block 18 to rotate around the axis of the insert cylinder 17. When the slide head 19 is located at the connection between the smooth groove 20 and the curved slide groove 22, the inclined locking block 18 is aligned with the groove in the support block 9. Then, as the insert rod 6 continues to slide away from the support block 9... When the rod 6 moves, the slider 19 slides along the inner wall of the smooth groove 20 until the slider 19 abuts against the inner wall of the smooth groove 20 at the end away from the support block 3 9. Then the rod 6 continues to slide away from the support block 3 9. The smooth groove 20 drives the insert cylinder 17 to slide and retract along the inner wall of the support block 3 9 towards the support block 1 5. The insert cylinder 17 simultaneously drives the inclined locking block 18 to move and retract into the support block 3 9, effectively preventing the inclined locking block 18 from colliding with personnel or other devices, thus protecting safety. Afterwards, the anti-slip steel plate 1 can be removed from the adjacent anti-slip steel plate 1. The disassembly process is simple and quick.
