Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a hoop fitting used in bridge construction. Background Technology

[0002] In bridge construction, ferrules are commonly used auxiliary components, primarily for temporary positioning, clamping, or providing support for bridge piers to ensure the smooth progress of subsequent construction procedures. With the continuous expansion of bridge construction scale and the diversification of construction conditions, increasingly higher requirements are being placed on the structural rationality and performance of ferrules.

[0003] Currently, most bridge construction clamping components on the market are of fixed specifications, with clamping spacing typically designed for specific bridge pier models. However, in actual construction scenarios, the spacing of bridge piers often varies depending on the bridge design, span requirements, and geological conditions of the construction area. A single project may involve the construction of bridge piers with multiple spacing specifications. These fixed-specification clamping components are difficult to adapt to bridge piers with different spacings, requiring construction companies to pre-order or purchase multiple models of clamping components for different spacings, increasing equipment procurement costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a clamping component for bridge construction.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a clamping component for bridge construction, comprising a square frame, wherein clamping assemblies are respectively provided on opposite side walls of the square frame, the clamping assembly comprising two extension plates spaced apart on the square frame, a U-shaped plate with an opening facing the square frame being horizontally slidably disposed between the two extension plates, a connecting plate being provided on the side of the U-shaped plate adjacent to the square frame, a driving assembly being provided on the square frame for driving the two connecting plates to move synchronously in opposite directions, a C-shaped plate with an opening direction opposite to that of the U-shaped plate being slidably disposed inside the U-shaped plate, a motion unit for driving the C-shaped plate to slide on the connecting plate, and a fixing unit for fixing the C-shaped plate, the U-shaped plate, and the extension plates on the C-shaped plate.

[0006] By adopting the above technical solution, a square frame and clamp assembly are set up. The drive assembly enables the two connecting plates to move synchronously in opposite directions, thereby causing the U-shaped plate to clamp both sides of the bridge column. The motion unit drives the C-shaped plate to slide within the U-shaped plate, forming an embracing structure between the U-shaped and C-shaped plates, which is then fixed to the bridge column. The fixing unit secures the C-shaped plate, U-shaped plate, and extension plate, preventing the U-shaped and C-shaped plates from loosening or shifting during construction. Simultaneously, the sliding of the U-shaped plate allows the clamp assembly to adapt to bridge columns with different spacings, enhancing the equipment's versatility and construction applicability, and reducing equipment replacement costs under different working conditions.

[0007] Furthermore, the driving assembly includes a bidirectional threaded iron rod rotatably mounted on a square frame. The bidirectional threaded iron rod has two sections of threads with opposite directions and equal pitch. A first internal threaded tube is provided on the side of the connecting plate adjacent to the square frame. The two first internal threaded tubes are respectively helically connected to the two sections of threads of the bidirectional threaded iron rod. The two first internal threaded tubes are symmetrically arranged. A first hexagonal block is fixedly sleeved in the middle of the bidirectional threaded iron rod.

[0008] By adopting the above technical solution, a bidirectional threaded iron rod is set. When the bidirectional threaded iron rod rotates, the two first internal threaded tubes drive the connecting plate to move synchronously in opposite directions, thereby adjusting the distance between the two U-shaped plates.

[0009] Furthermore, the motion unit includes a first threaded rod rotatably mounted on a connecting plate, a second internally threaded tube that is helically mounted on the first threaded rod and connected to a C-shaped plate, and a second hexagonal block that is fixedly sleeved on the first threaded rod.

[0010] By adopting the above technical solution, a first threaded rod and a second internal threaded tube are set up, and rotating the first threaded rod drives the second internal threaded tube and the C-shaped plate to move.

[0011] Furthermore, the fixing unit includes mounting plates disposed on both sides of the C-shaped plate and parallel to the extension plate. The mounting plates are provided with four sliding rods arranged in a rectangular array. The U-shaped plate has two vertically spaced first strip holes horizontally opened on opposite side walls. The extension plate has two vertically spaced second strip holes horizontally opened. The sliding rods slide in cooperation with the corresponding first and second strip holes. The end of the sliding rod is provided with a second threaded rod, and a nut is screwed onto the second threaded rod.

[0012] By adopting the above technical solution, a mounting plate, a second threaded rod, and a nut are set up. The sliding rod on the mounting plate forms a sliding fit with the first strip hole of the U-shaped plate and the second strip hole of the extension plate. This not only provides guidance for the sliding of the C-shaped plate and the U-shaped plate, but also fixes them by the screw locking of the second threaded rod and the nut after the C-shaped plate is adjusted to the position, so that the C-shaped plate, the U-shaped plate and the extension plate form a stable overall structure.

[0013] Furthermore, the end of the slide bar passes through the first strip hole and is arranged near the extension plate away from the U-shaped plate, and the diameter of the second threaded rod is smaller than the diameter of the slide bar.

[0014] By adopting the above technical solution, the slide rod end is arranged near the extension plate away from the U-shaped plate, so that part of the second threaded rod body is located in the second strip hole, ensuring that there is sufficient locking force when the nut is locked.

[0015] Furthermore, the top surface of the extension plate is provided with scale lines at equal intervals along the length direction, and the connecting plate is provided with positioning pointers corresponding to the scale lines.

[0016] By adopting the above technical solution, setting scale lines and positioning pointers, the scale lines on the extension plate and the positioning pointers on the connecting plate are coordinated to provide operators with an intuitive position reference, enabling operators to quickly judge the movement distance of the connecting plate.

[0017] Furthermore, the U-shaped plate and the C-shaped plate each have several arc-shaped strips vertically spaced on their arc-shaped inner walls.

[0018] By adopting the above technical solution and setting up an arc-shaped strip, the contact between the arc-shaped strip and the surface of the bridge column is a line contact, which can generate greater pressure than a planar contact, making the clamping more secure.

[0019] Furthermore, an arc-shaped rubber sheet is provided on the arc-shaped inner wall of the U-shaped plate and the C-shaped plate between two adjacent arc-shaped strips.

[0020] By adopting the above technical solution and setting an arc-shaped rubber sheet, the gap between the arc-shaped strips can be filled, further enhancing the stability of the clamping.

[0021] In summary, this utility model has the following beneficial effects: In this application, a square frame and clamp assembly are provided. The driving assembly enables the two connecting plates to move synchronously in opposite directions, thereby causing the U-shaped plate to clamp both sides of the bridge column. The motion unit drives the C-shaped plate to slide within the U-shaped plate, forming an embracing structure between the U-shaped plate and the C-shaped plate, which is then fixed to the bridge column. The fixing unit secures the C-shaped plate, the U-shaped plate, and the extension plate, preventing the U-shaped plate and C-shaped plate from loosening or shifting during construction. Simultaneously, the sliding of the U-shaped plate allows the clamp assembly to adapt to bridge columns with different spacings, enhancing the equipment's versatility and construction applicability, and reducing equipment replacement costs under different working conditions.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1-3 As shown in the embodiment of this application, a clamping component for bridge construction is disclosed, including a square frame 10 and clamping assemblies. There are two clamping assemblies, which are respectively disposed on opposite side walls of the square frame 10, and the square frame 10 supports the clamping assemblies. The clamping assembly includes two extension plates 20 spaced apart on the square frame 10. A U-shaped plate 21 with an opening facing the square frame 10 is horizontally slidably disposed between the two extension plates 20. A connecting plate 22 is disposed on the side of the U-shaped plate 21 adjacent to the square frame 10. A driving assembly 30 is disposed on the square frame 10 for driving the two connecting plates 22 to move synchronously in opposite directions. A C-shaped plate 23 with an opening direction opposite to that of the U-shaped plate 21 is slidably disposed inside the U-shaped plate 21. A motion unit 40 for driving the C-shaped plate 23 to slide is disposed on the connecting plate 22. A fixing unit 50 for fixing the C-shaped plate 23 to the U-shaped plate 21 and the extension plates 20 is also disposed on the C-shaped plate 23. The drive assembly 30 enables the two connecting plates 22 to move synchronously in opposite directions, thereby driving the U-shaped plate 21 to clamp both sides of the bridge column. The motion unit 40 drives the C-shaped plate 23 to slide within the U-shaped plate 21, forming an embracing structure of the U-shaped plate 21 and C-shaped plate 23 that is fixed to the bridge column. The fixing unit 50 fixes the C-shaped plate 23, the U-shaped plate 21, and the extension plate 20, preventing the U-shaped plate 21 and C-shaped plate 23 from loosening or shifting during construction. At the same time, the sliding of the U-shaped plate 21 allows the clamp assembly to adapt to bridge columns with different spacings, enhancing the versatility and construction applicability of the equipment and reducing the equipment replacement cost under different working conditions.

[0026] Specifically, the drive assembly 30 includes a bidirectional threaded iron rod 31 rotatably mounted on a square frame 10. Two fixing holes are provided on the square frame 10, and bearings are installed within these holes. The outer ring of the bearing is fixedly connected to the fixing hole, and the inner ring is fixedly connected to the bidirectional threaded iron rod 31, ensuring the flexibility and stability of the rotation of the bidirectional threaded iron rod 31. The bidirectional threaded iron rod 31 has two sections of threads with opposite directions and equal pitch. A first internal threaded tube 32 is provided on the side of the connecting plate 22 adjacent to the square frame 10. The two first internal threaded tubes 32 are respectively helically connected to the two sections of threads on the bidirectional threaded iron rod 31. The two first internal threaded tubes 32 are symmetrically arranged. Rotation of the bidirectional threaded iron rod 31 causes the two first internal threaded tubes 32 to drive the connecting plate 22 to move synchronously in opposite directions, adjusting the distance between the two U-shaped plates 21. A first hexagonal block 33 is fixedly sleeved in the middle of the bidirectional threaded iron rod 31. The first hexagonal block 33 provides a convenient force application point for the rotation of the bidirectional threaded iron rod 31, facilitating quick adjustment of the clamping state by the operator using tools, thus improving construction efficiency.

[0027] In setup, the motion unit 40 includes a first threaded rod 41 rotatably mounted on the connecting plate 22. A second internally threaded tube 42, connected to the C-shaped plate 23, is helically mounted on the first threaded rod 41. A second hexagonal block 43 is fixedly sleeved on the first threaded rod 41. Rotating the first threaded rod 41 drives the second internally threaded tube 42 and the C-shaped plate 23 to move. The second hexagonal block 43 provides a convenient force application point for the first threaded rod 41, facilitating quick adjustment of the clamping state by the operator using tools. The second hexagonal block 43 and the first hexagonal block 33 have identical shapes, allowing the operator to use the same type of tool to adjust the clamping assembly, reducing operational difficulty. The helical drive has self-locking properties, enabling the C-shaped plate 23 to stably maintain its current position after adjustment.

[0028] The fixing unit 50 includes a mounting plate 51 disposed on both sides of the C-shaped plate 23 and parallel to the extension plate 20. The mounting plate 51 has four sliding rods 52 arranged in a rectangular array. The U-shaped plate 21 has two horizontally spaced vertically spaced first strip holes on its opposite side walls. The extension plate 20 has two horizontally spaced vertically spaced second strip holes. The sliding rods 52 slide in contact with the corresponding first and second strip holes. A second threaded rod 53 is provided at the end of each sliding rod 52, and a nut 54 is screwed onto the second threaded rod 53. The sliding engagement between the sliding rods 52 on the mounting plate 51 and the first and second strip holes of the U-shaped plate 21 and the extension plate 20 provides guidance for the sliding of the C-shaped plate 23 and the U-shaped plate 21. After the C-shaped plate 23 is adjusted to its position, the screw locking of the second threaded rod 53 and the nut 54 secures the C-shaped plate 23, the U-shaped plate 21, and the extension plate 20, forming a stable overall structure. The end of the slide rod 52 passes through the first strip hole and is positioned near the extension plate 20 away from the U-shaped plate 21. This arrangement ensures that a portion of the second threaded rod 53 is located within the second strip hole, providing sufficient locking force when the nut 54 is tightened. The diameter of the second threaded rod 53 is smaller than that of the slide rod 52 to prevent it from scratching the second strip hole and to ensure smooth sliding of the slide rod 52.

[0029] In specific setup, the top surface of the extension plate 20 is provided with equally spaced scale lines 24 along its length, and the connecting plate 22 is provided with positioning pointers 25 corresponding to the scale lines 24. The scale lines 24 on the extension plate 20 and the positioning pointers 25 on the connecting plate 22 work together to provide operators with an intuitive positional reference, enabling them to quickly determine the movement distance of the connecting plate 22 and the spacing between the two U-shaped plates 21, thus aligning with the specified distance between the two bridge columns. This visual positioning method reduces reliance on operational experience, allowing even novice operators to quickly and accurately adjust the position, improving construction standardization and consistency, reducing rework caused by installation deviations, and indirectly improving construction progress.

[0030] Both the U-shaped plate 21 and the C-shaped plate 23 have several vertically spaced arc-shaped strips 26 on their arc-shaped inner walls. The contact between the arc-shaped strips 26 and the surface of the bridge column is a line contact, which generates greater pressure than a planar contact, resulting in a more secure clamping. Arc-shaped rubber sheets 27 are positioned between adjacent arc-shaped strips 26 on the arc-shaped inner walls of the U-shaped plate 21 and the C-shaped plate 23. The arc-shaped rubber sheets 27 fill the gaps between the arc-shaped strips 26, further enhancing the stability of the clamping. Simultaneously, the arc-shaped rubber sheets 27 possess good elasticity and cushioning properties. Furthermore, the elasticity of the rubber sheets can adapt to minor unevenness on the surface of the component, improving the adaptability of the clamping assembly to bridge columns with different surface conditions.

[0031] The operating principle of a clamping component for bridge construction in this embodiment is as follows: During use, the operator first uses a tool to rotate the first hexagonal block 33, causing the bidirectional threaded iron rod 31 to rotate. The two first internally threaded tubes 32, which are helically connected to it, will cause the connecting plate 22 to move synchronously in the opposite direction along the extension plate 20. At this time, the distance between the two U-shaped plates 21 can be determined by the scale line 24 on the extension plate 20 and the positioning pointer 25 on the connecting plate 22, until the open side of the U-shaped plate 21 is in contact with both sides of the bridge column. The scale line 24 is then observed to determine if it is correct, thus confirming the correctness of the bridge column spacing. Subsequently, the operator uses a tool to rotate the second hexagonal block 43 on the connecting plate 22, causing the first threaded rod 41 to rotate and drive the second internally threaded tube 42 to slide the C-shaped plate 23 within the U-shaped plate 21, allowing the C-shaped plate 23 and the U-shaped plate 21 to form a closed structure that encircles the bridge column. Finally, tighten the nut 54. Through the spiral locking action of the second threaded rod 53 and the nut 54, fix the slide rod 52 in the first strip hole of the U-shaped plate 21 and the second strip hole of the extension plate 20, so that the C-shaped plate 23, the U-shaped plate 21 and the extension plate 20 form a stable whole, and complete the installation and fixing of the sleeve assembly.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
