The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0031] Example 1
[0032] like Figures 1-2 As shown, this embodiment proposes a longitudinal embedded steel plate positioning fixture, including a connecting plate 2, a fixing plate 1 fixedly connected to one end of the connecting plate 2, the fixing plate 1 and the connecting plate 2 being fixed by welding, a sliding plate 5 slidably connected to the other end of the connecting plate 2, and a sliding bolt 4 for locking the sliding of the connecting plate 2 and the sliding plate 5.
[0033] A clamping plate 10 is provided on one side of the fixing plate 1. The fixing plate 1 is connected to a side plate 9. The side plate 9 and the clamping plate 10 cooperate to clamp the steel plate 21. It also includes a clamping bolt 11 that can drive the clamping plate 10 to move closer to the fixing plate 1. By tightening the clamping bolt 11, the clamping plate 10 is driven to move closer to the fixing plate 1. The clamping plate 10 and the side plate 9 cooperate to clamp the steel plate 21.
[0034] It is easy to operate. By placing the clamps on the top of the arch formwork according to the actual conditions of the construction site, the longitudinal embedded steel plate can be fixed. It is easy to process. The positioning clamps can quickly and accurately install the drainage steel plate, reducing the time for on-site measurement and adjustment, improving construction efficiency, and effectively shortening the construction period.
[0035] Both the connecting plate 2 and the sliding plate 5 are provided with a sliding groove 3. At least two sliding bolts 4 are provided in the sliding groove 3. The sliding bolts 4 can move in the sliding groove 3. The clamping plate 10 and the fixing plate 1 are in contact with each other, and the sliding plate 5 is located on one side of the connecting plate 2 and is also in contact with each other.
[0036] Two sliding bolts 4 are provided. After passing through the sliding groove 3, the sliding bolts 4 are threadedly connected to sliding nuts. One sliding nut is tightened and abuts against the connecting plate 2, and the other sliding nut is tightened and abuts against the sliding plate 5. The two sliding bolts 4 can realize the limiting work of the connecting plate 2 and the sliding plate 5, and prevent relative sliding between the connecting plate 2 and the sliding plate 5.
[0037] It also includes a support 6 fixed on the ground. The support 6 and the sliding plate 5 are detachably connected. The support 6 and the sliding plate 5 are connected by a thread, thereby realizing the detachable connection between the support 6 and the sliding plate 5. The lower support 6 is threaded with a screw, which can realize the connection between the support 6 and the ground, thereby realizing the fixation of the position of the sliding plate 5.
[0038] The sliding plate 5 is fixedly connected to a fixing nut 7, and the fixing nut 7 is threadedly connected to a lifting bolt 8. By tightening the lifting bolt 8 downwards, the lifting bolt 8 can be made to contact the ground, thereby adjusting the angle of the sliding plate 5 and supporting the sliding plate 5.
[0039] The fixing plate 1 and the clamping plate 10 have through holes for the clamping bolt 11 to move freely. The clamping bolt 11 passes through the through hole and is threaded to the clamping nut 12. One end of the clamping bolt 11 abuts against the clamping plate 10, and the other end of the clamping bolt 11 is threaded to the clamping nut 12. After the clamping nut 12 is tightened, it abuts against the fixing plate 1. By tightening the clamping nut 12, the clamping plate 10 can be driven to move closer to the fixing plate 1.
[0040] The clamping bolt 11 also has another connection method. The clamping bolt 11 and the clamping plate 10 are fixedly connected. The fixing plate 1 has a through hole for the clamping bolt 11 to move freely. The clamping bolt 11 can slide or rotate in the through hole. After the clamping bolt 11 passes through the through hole, it is threadedly connected to the clamping nut 12. The clamping nut 12 abuts against the fixing plate 1.
[0041] A reinforcing rib 13 is fixedly connected between the fixing plate 1 and the connecting plate 2. The two ends of the reinforcing rib 13 are welded to achieve the fixed connection between the fixing plate 1 and the connecting plate 2. By setting the reinforcing rib 13, the stability of the connection between the fixing plate 1 and the connecting plate 2 can be further improved.
[0042] Example 2
[0043] Reference Appendix Figures 3-5 The other structures are the same as in Embodiment 1, except that the adjustment of the side plates is taken into account in this embodiment.
[0044] The fixed plate 1 has a lifting groove 16, which is opened vertically. A lifting plate 15 is slidably connected in the lifting groove 16. The lifting plate 15 can only slide vertically. There are two side plates 9, which are located on both sides of the lifting plate 15. The two ends of the lifting plate 15 are fixedly connected to the side plates 9 on both sides respectively. The side plates 9 can slide along the surface of the fixed plate 1.
[0045] The lifting plate 15 is fixedly connected to the lifting bolt 14. The reinforcing rib 13 has a sliding hole for the lifting bolt 14 to move freely. The lifting bolt 14 passes through the through hole and is threadedly connected to the lifting nut 17. The lower end of the lifting nut 17 abuts against the reinforcing rib 13. By rotating the lifting nut 17, the lifting bolt 14 can be driven to rise, which in turn drives the side plate 9 to rise through the lifting plate 15, so that the side plate 9 can better fit with the steel plate 21, thereby cooperating with the clamping plate 10 to better achieve the clamping work of the steel plate 21, improve the clamping effect, and thus better achieve the positioning of the steel plate 21.
[0046] Example 3
[0047] Reference Appendix Figures 6-7 The other structures are the same as in Embodiment 1, except that the clamping problem of the steel plate is taken into account in this embodiment.
[0048] The fixed plate 1 is slidably connected to the push plate 22, and the push plate 22 is fixedly connected to the guide rod 23. The guide rod 23 and the fixed plate 1 are slidably connected. There are two side plates 9, and both side plates 9 are fixedly connected to the fixed plate 1. The push plate 22 is located between the two side plates 9.
[0049] The push plate 22 is rotatably connected to two ends of a connecting rod 19. The connecting rod 19 is connected to a rotating wheel that abuts against the steel plate 21. A tension spring 20 is connected between the two connecting rods 19. The rotating wheel and the connecting rod 19 are rotatably connected. When the push plate 22 moves toward the steel plate 21, the connecting rod 19 can rotate around the push plate 22, causing the tension spring 20 to be stretched. At this time, the rotating wheel rolls along the surface of the steel plate 21.
[0050] The fixed plate 1 is threadedly connected with a tightening bolt 18, which is rotatably connected to the push plate 22. By rotating the tightening bolt 18, the push plate 22 can be driven to move horizontally. The rotating wheel can clamp the two sides of the steel plate 21. To address the issue of different inclinations of the steel plate 21, the rotatable connecting rod 19 can better clamp the steel plate 21, improve the applicability of the device, and further enhance the clamping effect.
[0051] The specific working process is as follows: By fixing the support 6 to the ground, the sliding nut is loosened. At this time, the sliding nut no longer abuts against the connecting plate 2 and the sliding plate 5. The sliding bolt 4 can slide in the groove 3. After adjusting the relative position of the connecting plate 2 and the sliding plate 5, the sliding nut is tightened. The two sliding nuts abut against the connecting plate 2 and the sliding plate 5 respectively, thereby realizing the relative locking between the connecting plate 2 and the sliding plate 5.
[0052] The fixing plate 1 is placed on the steel plate 21. At this time, the steel plate 21 is located between the clamping plate 10 and the side plate 9. By tightening the clamping nut 12, the clamping nut 12 drives the clamping bolt 11 to move. The clamping bolt 11 drives the clamping plate 10 to move closer to the fixing plate 1. The clamping plate 10 and the side plate 9 cooperate with each other to achieve the clamping work of the steel plate 21.
[0053] To address the issue of varying heights of the steel plates 21, the structure described in Embodiment 2 is adopted. In this case, rotating the lifting nut 17 can drive the lifting bolt 14 to rise, which in turn drives the side plate 9 to rise through the lifting plate 15, allowing the side plate 9 to better fit against the steel plate 21 and thus cooperate with the clamping plate 10. At this time, the lifting nut 17 abuts against the reinforcing rib 13, better achieving the clamping operation of the steel plate 21.
[0054] To address the issue of varying side inclination angles of the steel plate 21, the structure described in Embodiment 3 is adopted. Rotating the fixing bolt 18 causes the push plate 22 to move closer to the steel plate 21. At this time, the connecting rod 19 rotates around the push plate 22, stretching the tension spring 20. The rotating wheel then rolls along the surface of the steel plate 21, enabling it to clamp both sides of the steel plate 21, thus adapting to steel plates 21 with different inclination angles. This also provides a good positioning effect for the steel plate 21.
[0055] Positioning clamps, spaced 2 meters apart, are arranged on the top of the invert arch formwork. These clamps ensure that the drainage steel plates are accurately installed in their designed positions during tunnel construction, preventing displacement due to external forces such as impact and vibration during concrete pouring. This ensures the effectiveness and stability of the drainage system. Using these clamps allows for quick and accurate installation of the drainage steel plates, reducing on-site measurement and adjustment time, improving construction efficiency, and shortening the construction period.
[0056] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
