Description

Technical Field

[0001] This utility model relates to the field of casting formwork support technology, specifically to an adjustable auxiliary support device for bridge construction. Background Technology

[0002] Bridge railings are guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going off the bridge, preventing vehicles from breaking through, passing under, or overturning the bridge, and also enhancing the aesthetics of the bridge structure. Cast-in-place reinforced concrete railings (whose steel frame is integrated with the bridge's steel frame) have high strength and can withstand the impact of motor vehicles, and can be directly installed along the edge of the roadway.

[0003] Cast-in-place reinforced concrete railings are very similar to cast-in-place walls, using columns or diagonal braces to limit the tilting of the formwork. In existing technology, the side formwork of concrete pouring is usually simply supported by inclined struts. Although the struts can prevent the side formwork from shifting or tilting in the horizontal direction, they cannot limit the movement of the side formwork in the vertical direction. Therefore, the side formwork is still prone to movement, which can lead to leakage during concrete pouring. In addition, the inclined struts mostly only support the middle area of ​​the formwork. The deformation caused by the support force of the fixed diagonal braces in the middle of the formwork is small, but other areas of the formwork still deform, which will eventually affect the flatness of the concrete railing and the structural strength of the concrete railing.

[0004] To address this, we propose an adjustable auxiliary support device for bridge construction. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an adjustable auxiliary support device for bridge construction. By supporting the formwork in multiple dimensions, the stress on the formwork is made more uniform, thus solving the deformation problem.

[0006] The technical solution adopted by this utility model is as follows:

[0007] This utility model discloses an adjustable auxiliary support device for bridge construction, comprising a base, a channel steel column, a horizontal support assembly, and a vertical clamping assembly. The channel steel column is fixedly mounted on the base, and a reinforcing rib is fixedly connected between the bottom of the channel steel column and the base. A threaded rod is rotatably mounted on the channel steel column, and a rotating handle is fixedly mounted on one end of the threaded rod. The horizontal support assembly is mounted on the threaded rod, and the vertical clamping assembly is mounted on the end of the threaded rod away from the channel steel column.

[0008] Furthermore, the horizontal support assembly includes a threaded sleeve, a sleeve, and a fixed sleeve. The threaded sleeve is threaded onto the threaded rod, and the sleeve is movably sleeved onto the threaded rod and located to the right of the threaded sleeve. One end of the sleeve is fixedly provided with an annular contact plate, the surface of which slides in contact with one end face of the threaded sleeve. A diagonal brace is hinged to the side wall of the sleeve, and a fixed plate is hinged to the end of the diagonal brace away from the sleeve. The fixed sleeve is fixedly sleeved onto the threaded rod and located to the right of the sleeve. Limiting rings are fixedly provided at both ends of the fixed sleeve. A sleeve is rotatably sleeved on the fixed sleeve and located between the limiting rings. A movable rod is hinged to the side wall of the sleeve, and the end of the movable rod away from the sleeve is hinged to the diagonal brace.

[0009] Furthermore, the horizontal support assembly also includes a return spring, which is slidably sleeved on the outside of the threaded rod. A second limiting ring is fixedly provided at the right end of the sleeve. One end of the return spring is fixedly connected to the second limiting ring, and the other end of the return spring is fixedly connected to the first limiting ring on the left side.

[0010] Furthermore, the vertical clamping assembly includes a lifting mechanism and a clamping mechanism. The lifting mechanism is located at the end of the threaded rod away from the channel steel column and is controlled by the threaded rod. The clamping mechanism is located at the top of the lifting mechanism and is driven to rise and fall by the lifting mechanism, thereby clamping the top of the template and preventing it from moving up and down.

[0011] Furthermore, the lifting mechanism includes a housing, a threaded cylinder, a lifting screw, and a lifting plate. One end of the threaded screw extends into the housing via a bearing. A reinforcing rod is fixed between the bottom of the housing and the channel steel column, and a reinforcing rod is fixed between the top of the housing and the channel steel column. The bottom end of the threaded cylinder is rotatably mounted on the inner bottom wall of the housing via a bearing, and the top end of the threaded cylinder rotatably penetrates the top of the housing. The lifting screw is threadedly connected to the threaded cylinder. The lifting mechanism also includes a bevel gear and a bevel gear. The bevel gear is fixedly mounted on the end of the threaded screw located inside the housing, and the bevel gear is fixedly mounted on the threaded cylinder. The bevel gear meshes with the bevel gear. The lifting plate is fixedly mounted on the top end of the lifting screw. Hollow rods are fixedly sleeved at both ends of the lifting plate, and the bottom end of the hollow rods slides through the top of the housing and extends into the housing. The lifting mechanism also includes a guide rod, which is fixedly mounted on the inner bottom wall of the housing and symmetrically located on the front and rear sides of the threaded cylinder. The guide rod slides through the hollow rod, and the clamping mechanism is located on the top end of the guide rod.

[0012] Furthermore, the clamping mechanism includes an adjusting plate and a fastening plate. The left end of the adjusting plate is slidably sleeved on the hollow rod. The surface of the hollow rod is provided with external threads. Two sets of locking nuts are threaded onto the hollow rod. The locking nuts are located on the upper and lower sides of the adjusting plate. One side wall of the fastening plate is hinged to the right end of the adjusting plate, and the fastening plate is fastened to the upper end of the template.

[0013] Furthermore, the fastening plate is configured in a U-shape, a rubber pad is adhered to the inner side wall of the fastening plate, and a guide ramp is provided at the end of the fastening plate.

[0014] Furthermore, the clamping mechanism also includes an auxiliary support unit, which is disposed between the adjusting plate and the hollow rod. The auxiliary support unit includes an auxiliary support rod, an adjusting sleeve, and a rotating sleeve. The adjusting sleeve is threaded onto the outside of the hollow rod, and the rotating sleeve is rotatably fitted onto the adjusting sleeve. The adjusting sleeve is fixedly fitted with two sets of limiting discs, and the rotating sleeve is located between the two sets of limiting discs. One end of the auxiliary support unit is hinged to the side wall of the rotating sleeve, and the other end of the auxiliary support unit is hinged to the bottom of the adjusting plate.

[0015] Furthermore, the lifting mechanism also includes a horizontal bar, with a connecting block fixedly provided at the top of the guide bar, one end of the horizontal bar being fixedly connected to the channel steel column, and the other end of the horizontal bar being fixedly connected to the connecting block.

[0016] Furthermore, the horizontal support assembly also includes a central connecting mechanism, which is located on the right side wall of the housing. The central connecting mechanism includes a threaded cylinder II, a support screw, and a fixing plate II. The threaded cylinder II is rotatably mounted on the right side wall of the housing via a bearing. The support screw is threadedly connected inside the threaded cylinder II. The fixing plate II is hinged to the end of the support screw away from the threaded cylinder II.

[0017] The beneficial effects of this utility model by adopting the above structure are as follows:

[0018] 1. This utility model utilizes the cooperation between the horizontal support component and the threaded rod. By rotating the threaded sleeve and the threaded rod relative to each other, the threaded sleeve moves, thereby squeezing the sleeve to move. In conjunction with the movable rod, the diagonal brace spreads outwards around the threaded rod, which in turn causes multiple sets of fixing plates to disperse. Through the spread-out fixing plates, the support area on the side of the template is expanded, making the template more evenly stressed and preventing deformation in other areas of the template. Ultimately, this would affect the flatness of the concrete guardrail and its structural strength.

[0019] 2. This utility model utilizes the cooperation between the vertical clamping component and the threaded rod. By loosening the threaded sleeve and rotating the handle, the threaded rod rotates, causing the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the first threaded cylinder to rotate. This causes the lifting screw to move downwards, which in turn drives the lifting plate to move downwards, which in turn drives the hollow rod to move downwards, which in turn drives the adjusting plate and the fastening plate to move downwards. This causes the fastening plate to fasten to the top of the template, fixing the top of the template and preventing leakage during concrete pouring caused by the template moving up and down.

[0020] 3. This utility model provides auxiliary support for the adjustment plate through the auxiliary support unit, preventing the adjustment plate from deforming under force and making the clamping plate more stable on the top of the template. When the right end of the adjustment plate is subjected to an upward pulling force, the auxiliary support rod plays an auxiliary pulling role to prevent the adjustment plate from deforming. When the right end of the adjustment plate is subjected to a downward pulling force, the auxiliary support rod plays an auxiliary support role, which can also prevent the adjustment plate from deforming.

[0021] 4. This utility model increases the connection stability between the horizontal support component and the vertical clamping component and the formwork by setting up reinforcing rod one, reinforcing rod two and the horizontal rod and connecting them with the channel steel column. In this way, by supporting the building casting formwork in multiple dimensions, the stress on the formwork is more uniform and the deformation problem is solved. Attached Figure Description

[0036] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] like Figures 1-11 As shown, this utility model discloses an adjustable auxiliary support device for bridge construction, comprising a base 1, a channel steel column 2, a horizontal support assembly 3, and a vertical clamping assembly 4. The channel steel column 2 is fixedly mounted on the base 1, and a reinforcing rib 5 is fixedly provided between the bottom of the channel steel column 2 and the base 1. A threaded rod 6 is rotatably mounted on the channel steel column 2, and a rotating handle 7 is fixedly mounted on one end of the threaded rod 6. The horizontal support assembly 3 is mounted on the threaded rod 6, and the vertical clamping assembly 4 is mounted on the end of the threaded rod 6 away from the channel steel column 2.

[0038] Working principle: The horizontal support component 3 is fixedly connected to the template to support the side of the template. The vertical clamping component 4 is engaged with the top of the template to prevent the template from moving up and down. The threaded rod 6 can control the expansion and contraction of the horizontal support component 3 and the raising and lowering of the vertical clamping component 4.

[0039] like Figures 1-11 As shown, the horizontal support assembly 3 includes a threaded sleeve 31, a sleeve 32, and a fixed sleeve 33. The threaded sleeve 31 is threadedly fitted onto the threaded rod 6. The sleeve 32 is movably fitted onto the threaded rod 6 and is located to the right of the threaded sleeve 31. An annular contact plate 34 is fixedly provided on one end of the sleeve 32, and the surface of the annular contact plate 34 slides in contact with one end face of the threaded sleeve 31. A diagonal brace 35 is hinged to the side wall of the sleeve 32. A fixed plate 36 is hinged to the end of the diagonal brace 35 away from the sleeve 32. The fixed sleeve 33 is fixedly fitted onto the sleeve 32. The fixed cylinder 33 is attached to the threaded rod 6 and located to the right of the sleeve 32. The fixed cylinder 33 can be fixed by threaded connection to the threaded rod 6. This can both fix the fixed cylinder 33 and adjust its position on the threaded rod 6. Limiting rings 37 are fixed at both ends of the fixed cylinder 33. A sleeve 38 is rotatably sleeved on the fixed cylinder 33 and is located between the limiting rings 37. A movable rod 39 is hinged to the side wall of the sleeve 38. The end of the movable rod 39 away from the sleeve 38 is hinged to the diagonal brace 35.

[0040] Working principle: Through the horizontal support component 3, the threaded sleeve 31 moves due to the relative rotation of the threaded sleeve 31 and the threaded rod 6, which in turn squeezes the sleeve 32 to move. In conjunction with the movable rod 39, the diagonal brace 35 spreads out to the surrounding area of ​​the threaded rod 6, thereby driving multiple sets of fixed plates 36 to disperse. Through the spread fixed plates 36, the support area on the side of the template is expanded, making the template more evenly stressed.

[0041] like Figures 1-11 As shown, the horizontal support assembly 3 also includes a return spring 310. The return spring 310 is slidably sleeved on the outside of the threaded rod 6. A second limiting ring 311 is fixedly provided at the right end of the sleeve 32. One end of the return spring 310 is fixedly connected to the second limiting ring 311, and the other end of the return spring 310 is fixedly connected to the first limiting ring 37 on the left side. The return spring 310 facilitates the reset of the sleeve 32 and also facilitates the storage of the diagonal brace 35.

[0042] like Figures 1-11As shown, the vertical clamping assembly 4 includes a lifting mechanism 41 and a clamping mechanism 42. The lifting mechanism 41 is located at the end of the threaded rod 6 away from the channel steel column 2, and is controlled by the threaded rod 6. The clamping mechanism 42 is located at the top of the lifting mechanism 41, and is raised and lowered by the lifting mechanism 41, thereby clamping the top of the template and preventing it from moving up and down. The lifting mechanism 41 includes a housing 411, a threaded cylinder 412, a lifting screw 413, and a lifting plate 414. One end of the threaded rod 6 extends into the housing 411 through a bearing. A reinforcing rod 415 is fixed between the bottom of the housing 411 and the channel steel column 2. A reinforcing rod 416 is fixed between the top of body 411 and channel steel column 2. The bottom end of threaded cylinder 412 is rotatably mounted on the bottom wall inside body 411 via a bearing. The top end of threaded cylinder 412 rotatably passes through the top of body 411. Lifting screw 413 is threadedly connected to threaded cylinder 412. Lifting mechanism 41 also includes bevel gear 417 and bevel gear 418. Bevel gear 417 is fixedly mounted on the end of threaded rod 6 located inside body 411. Bevel gear 418 is fixedly mounted on threaded cylinder 412. Bevel gear 417 and bevel gear 418 mesh. Lifting plate 414 is fixedly mounted on the top end of lifting screw 413. The lifting plate 414 has hollow rods 419 fixedly sleeved at both ends. The bottom end of the hollow rods 419 slides through the top of the housing 411 and extends into the housing 411. The lifting mechanism 41 also includes a guide rod 4110, which is fixedly mounted on the bottom wall inside the housing 411 and symmetrically located on the front and rear sides of the threaded cylinder 412. The guide rods 4110 slide through the hollow rods 419. A clamping mechanism 42 is located on the top of the guide rods 4110. The clamping mechanism 42 includes an adjusting plate 421 and a fastening plate 422. The left end of the adjusting plate 421 is slidably sleeved on the hollow rods 419. The surface of the hollow rods 419 is provided with external threads. The hollow rod 419 is threaded with two sets of locking nuts 423, which are located on the upper and lower sides of the adjusting plate 421. The side wall of the fastening plate 422 is hinged to the right end of the adjusting plate 421. The fastening plate 422 is fastened to the upper end of the template. The height of the adjusting plate 421 can be adjusted by the two sets of locking nuts 423 to accommodate templates of different heights. The fastening plate 422 is designed in a U-shape. A rubber pad is glued to the inner side wall of the fastening plate 422. A guide plate 424 is provided at the end of the fastening plate 422. The guide plate 424 makes it easier for the fastening plate 422 to be fastened to the top of the template.

[0043] Working principle: Through the vertical clamping component 4, by loosening the threaded sleeve 31 and rotating the handle 7, the threaded rod 6 is driven to rotate. At this time, the threaded sleeve 31 will rotate together with the threaded rod 6 without relative movement. The rotation of the threaded rod 6 will drive the first bevel gear 417 to rotate, which in turn drives the second bevel gear 418 to rotate, which in turn drives the first threaded cylinder 412 to rotate, which in turn drives the lifting screw 413 to move downward, which in turn drives the lifting plate 414 to move downward, which in turn drives the hollow rod 419 to move downward, which in turn drives the adjusting plate 421 and the fastening plate 422 to move downward, so that the fastening plate 422 is fastened to the top of the template, fixing the top of the template and preventing the template from moving up and down, which could cause leakage during concrete pouring.

[0044] like Figures 1-11 As shown, the clamping mechanism 42 also includes an auxiliary support unit 425, which is located between the adjusting plate 421 and the hollow rod 419. The auxiliary support unit 425 includes an auxiliary support rod 4251, an adjusting sleeve 4252, and a rotating sleeve 4253. The adjusting sleeve 4252 is threaded onto the outside of the hollow rod 419, and the rotating sleeve 4253 is rotatably fitted onto the adjusting sleeve 4252. The adjusting sleeve 4252 is fixedly fitted with two sets of limiting discs 4254, and the rotating sleeve 4253 is located between the two sets of limiting discs 4254. One end of the auxiliary support unit 425 is hinged to the side wall of the rotating sleeve 4253, and the other end of the auxiliary support unit 425 is hinged to the bottom of the adjusting plate 421.

[0045] The auxiliary support unit 425 provides auxiliary support for the adjusting plate 421, preventing deformation of the adjusting plate 421 under stress and making the clamping plate 422 more stable in pressing the top of the template. In use, by rotating the adjusting sleeve 4252, the limiting plate 4254 is moved, which in turn moves the auxiliary support rod 4251, thereby moving the adjusting plate 421. After adjustment, the adjusting plate 421 is locked by two sets of locking nuts 423. When the right end of the adjusting plate 421 is subjected to an upward pulling force, the auxiliary support rod 4251 plays an auxiliary pulling role to prevent deformation of the adjusting plate 421. When the right end of the adjusting plate 421 is subjected to a downward pulling force, the auxiliary support rod 4251 plays an auxiliary support role, which can also prevent deformation of the adjusting plate 421.

[0046] like Figures 1-11 As shown, the lifting mechanism 41 also includes a horizontal bar 4111. A connecting block 4112 is fixedly provided at the top of the guide bar 4110. One end of the horizontal bar 4111 is fixedly connected to the channel steel column 2, and the other end of the horizontal bar 4111 is fixedly connected to the connecting block 4112. By setting the horizontal bar 4111, the stability of the guide bar 4110 is improved, which in turn improves the stability of the hollow bar 419, the adjusting plate 421 and the fastening plate 422, and further improves the stability of the fastening plate 422 pressing the top of the template.

[0047] like Figures 1-11 As shown, the horizontal support assembly 3 also includes a central connecting mechanism 312, which is located on the right side wall of the housing 411. The central connecting mechanism includes a threaded cylinder 3121, a support screw 3122, and a fixing plate 3123. The threaded cylinder 3121 is rotatably mounted on the right side wall of the housing 411 via a bearing. The support screw 3122 is threadedly connected inside the threaded cylinder 3121. The fixing plate 3123 is hinged to the end of the support screw 3122 away from the threaded cylinder 3121.

[0048] The central connecting mechanism 312 provides support for the middle part of the template. The threaded engagement between the threaded cylinder 3121 and the support screw 3122 allows for adjustment of the distance between the fixing plate 3123 and the template, facilitating the installation of the fixing plate 3123 on the template.

[0049] In practical use, the operator holds the rotating handle 7 still with one hand and rotates the threaded sleeve 31 with the other, causing the threaded sleeve 31 to move to the right along the threaded rod 6. This moves the sleeve 32 to the right and compresses the return spring 310. Since one end of the movable rod 39 is hinged to the sleeve 38, and the sleeve 38 is rotatably fitted onto the fixed cylinder 33, when the sleeve 32 moves to the right, the movable rod 39 drives the diagonal brace 35 to spread out around the threaded rod 6, thereby causing multiple sets of fixing plates 36 to disperse. The engagement areas of fixing plates 36, 3123, and 422 are adjusted to be on the same vertical plane, with the fastening plate 422 directly above the template. Then, fixing plates 36 and 3123 are fixedly connected to the template, thus providing fixed support to the side of the template. 6. The support area of ​​the template is expanded, making the template more evenly stressed. Then, loosen the threaded sleeve 31 and rotate the handle 7 to drive the threaded rod 6 to rotate. At this time, the threaded sleeve 31 will rotate with the threaded rod 6 without relative movement. The rotation of the threaded rod 6 will drive the bevel gear 1 417 to rotate, which in turn drives the bevel gear 2 418 to rotate, which in turn drives the threaded cylinder 1 412 to rotate, which in turn drives the lifting screw 413 to move downward, which in turn drives the lifting plate 414 to move downward, which in turn drives the hollow rod 419 to move downward, which in turn drives the adjusting plate 421 and the fastening plate 422 to move downward, so that the fastening plate 422 is fastened to the top of the template, fixing the top of the template and preventing the template from moving up and down. Finally, the base 1 is fixed to the ground with bolts, thereby fixing the channel steel column 2, thus completing the installation of this device.

[0050] After the concrete has been poured and reached the design strength, disassemble the device in reverse order according to the usage procedure. First, disassemble the base 1, then remove the fixing plate 36 and fixing plate 3123 from the template. Then, rotate the handle 7 in the opposite direction to disengage the fastening plate 422 from the top of the template. Hold the handle 7 with one hand and keep it still, while rotating the threaded sleeve 31 in the opposite direction with the other hand to move the threaded sleeve 31 to the left. Under the rebound force of the return spring 310, the sleeve 32 moves to the left, causing the multiple sets of diagonal braces 35 to move and be stored on the side of the threaded rod 6. Store the diagonal braces 35 and finally move the device out of the construction site.
