Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a pier clamping device. Background Technology

[0002] During bridge construction, for high-pier bridges, ladders or steel pipe columns are often installed on the pier body to support the workers. To ensure the vertical stability of the ladders or steel pipe columns, steel plates are often embedded in the pier body or reserved openings are used for connection. After construction, the embedded steel plates need to be rust-proofed or the reserved openings need to be filled to avoid affecting the later use of the pier body.

[0003] However, rust prevention treatment of embedded steel plates increases the workload of construction workers, and substandard rust prevention treatment can lead to rust on the pier body, affecting the strength of the pier body and posing a safety hazard. Filling the reserved openings also increases the workload of construction workers, and improper treatment of the reserved openings can result in gaps or cracks in the pier body. Stress concentration can occur at the tips of the gaps or cracks, reducing the load-bearing capacity and service life of the pier body. Utility Model Content

[0004] The purpose of this utility model is to provide a pier clamping device to reduce the workload of construction workers and improve the support strength and service life of piers.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A pier clamping device, comprising:

[0007] A clamping assembly includes a clamping plate and a connecting plate. A plurality of the clamping plates are arranged around the pier and can fit against at least a portion of the outer surface of the pier. The connecting plate is fixedly connected to the clamping plates. A plurality of the connecting plates are arranged opposite to each other on the side of the clamping plate away from the pier. The connecting plates are arranged at an angle to the clamping plates. The connecting plates are provided with connecting holes.

[0008] A connecting screw is sequentially inserted into the connecting holes of two oppositely arranged connecting plates, and both ends of the connecting screw protrude from the connecting plates;

[0009] Locking nuts, two of which are screwed to the two ends of the connecting screw, can press against the connecting plate so that the clamping assembly surrounds and clamps the pier column.

[0010] In the aforementioned pier clamping device, the connecting plate is a rectangular plate, and two connecting plates extending vertically are fixedly connected to each clamping plate.

[0011] The aforementioned pier clamping device further includes a first reinforcing member, a plurality of the first reinforcing members being arranged vertically between the two connecting plates, and the two ends of the first reinforcing members being fixedly connected to the two connecting plates respectively.

[0012] In the aforementioned pier clamping device, the first reinforcing member is plate-shaped and extends horizontally.

[0013] In the aforementioned pier clamping device, each connecting plate has two connecting holes spaced apart in the vertical direction, and the two corresponding connecting holes on each clamping plate are aligned in the horizontal direction.

[0014] In the aforementioned pier clamping device, two connecting screws extending horizontally are arranged vertically between two adjacent connecting plates, and the two connecting screws are sequentially inserted into their corresponding connecting holes.

[0015] The aforementioned pier clamping device, wherein the pier has a rounded rectangular cross-section, the clamping plate has an arc surface and a straight surface, the arc surface can fit against the rounded corner edge of the pier, and the straight surfaces on both sides of the arc surface can respectively fit against the planes on both sides of the rounded corner edge of the pier.

[0016] The aforementioned pier clamping device further includes two sets of second reinforcing members, each set of second reinforcing members being fixedly connected to the connecting plate and the clamping plate, and connected to the opposite side of the connecting plate.

[0017] The aforementioned pier clamping device includes a set of second reinforcing members comprising multiple reinforcing plates spaced apart along the vertical direction, the cross-sectional shape of which is triangular or trapezoidal.

[0018] In the aforementioned pier clamping device, the top surface of the connecting plate is flush with the top surface of the clamping plate, and the bottom surface of the connecting plate is flush with the bottom surface of the clamping plate.

[0019] The beneficial effects of this utility model are:

[0020] The pier clamping device provided by this utility model features a clamping plate that fits snugly against the pier. The clamping plate is fixedly connected to a connecting plate, which has connecting holes for threaded connecting bolts to connect the clamping components end-to-end. A locking nut is screwed onto the connecting bolt, allowing multiple clamping components to surround and clamp the pier. In use, the pier clamping device only requires multiple clamping components to be positioned around the outer surface of the pier, and the locking nut to be adjusted to lock the components in place. This eliminates the need for pre-embedded steel plates or pre-drilled openings in the pier, reducing subsequent maintenance of steel plates and openings and lowering the workload for construction workers. Furthermore, the clamping components do not damage the pier's structure, ensuring its load-bearing capacity and service life. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] This utility model provides a pier column clamping device that directly clamps and fixes the pier column, avoiding the need to pre-embed steel plates or reserve holes in the pier column, reducing the workload of construction personnel, and improving the support strength and service life of the pier column.

[0034] like Figures 1 to 3 As shown, the pier clamping device includes a clamping assembly 1, a connecting screw 2, and a locking nut 3. The clamping assembly 1 includes a clamping plate 11 and a connecting plate 12. Multiple clamping plates 11 are arranged around the pier 100 and can fit against at least part of the outer surface of the pier 100. The connecting plate 12 is fixedly connected to the clamping plate 11. Multiple oppositely arranged connecting plates 12 are arranged on the side of the clamping plate 11 away from the pier 100. The connecting plate 12 and the clamping plate 11 are arranged at an angle. The connecting plate 12 has a connecting hole 121. The connecting screw 2 passes through the connecting holes 121 of the two oppositely arranged connecting plates 12 in sequence, and the two ends of the connecting screw 2 protrude from the connecting plate 12. Two locking nuts 3 are respectively screwed to the two ends of the connecting screw 2. The locking nuts 3 can press against the connecting plate 12 so that the clamping assembly 1 surrounds and clamps the pier 100.

[0035] The pier clamping device provided by this utility model has a clamping plate 11 that fits against the pier 100. The clamping plate 11 is fixedly connected to a connecting plate 12, which has a connecting hole 121 for inserting a connecting screw 2 to connect the clamping components 1 end to end. A locking nut 3 is screwed onto the connecting screw 2 so that multiple clamping components 1 are arranged around and clamped to the pier 100. In use, the pier clamping device only requires multiple clamping components 1 to be arranged around the outer surface of the pier 100, and the locking nut 3 to be adjusted to lock the clamping components 1 to the pier 100. There is no need to pre-embed steel plates or reserve openings in the pier 100, reducing subsequent maintenance of steel plates and openings and lowering the workload of construction personnel. Furthermore, the clamping components 1 do not damage the structure of the pier 100, ensuring the load-bearing capacity and service life of the pier 100.

[0036] This embodiment does not specifically limit the shape of the clamping plate 11; the shape of the clamping plate 11 can be designed according to the shape of the pier 100. For example, the cross-section of the pier 100 is a rounded rectangle, and the clamping plate 11 has an arc surface and a straight surface. The arc surface can fit against the rounded corner edge of the pier 100, and the straight surfaces on both sides of the arc surface can respectively fit against the planes on both sides of the rounded corner edge of the pier 100. This improves the fit between the clamping plate 11 and the pier 100, increases the force-bearing area, reduces the interaction force between the clamping plate 11 and the pier 100, and improves the service life.

[0037] Specifically, four clamping plates 11 are provided, and the four clamping plates 11 are respectively provided at the four rounded corners of the pier column 100.

[0038] In other embodiments, the cross-section of the pier 100 is circular, the clamping plate 11 has an arc surface, and two clamping plates 11 are provided. The two clamping plates 11 are arranged opposite to each other on both sides of the pier 100, and the arc surface of the clamping plate 11 is attached to the outer surface of the pier 100.

[0039] Each clamping plate 11 may have two connecting plates 12, or multiple connecting plates 12. Optionally, see [link to relevant documentation]. Figure 1 The connecting plate 12 is a rectangular plate, and two connecting plates 12 extending vertically are fixedly connected to each clamping plate 11. This facilitates processing and connection.

[0040] This embodiment does not specifically limit the size of the connecting plate 12; the size of the connecting plate 12 needs to be referenced to the size of the clamping plate 11. For example, the top surface of the connecting plate 12 is flush with the top surface of the clamping plate 11, and the bottom surface of the connecting plate 12 is flush with the bottom surface of the clamping plate 11. The flush design of the end faces of the connecting plate 12 and the clamping plate 11 ensures that the connecting plate 12 and the clamping plate 11 are subjected to uniform force, avoiding stress abrupt changes caused by step differences, which could lead to fatigue cracks and reduce the strength of the clamping assembly 1.

[0041] In other embodiments, each clamping plate 11 is provided with six connecting plates 12, the six connecting plates 12 are divided into two groups, each group has three connecting plates 12, the three connecting plates 12 in each group extend vertically and are spaced apart vertically, the two groups of connecting plates 12 are spaced apart horizontally, and the connecting plates 12 at corresponding positions in the two groups are aligned horizontally.

[0042] The connecting plate 12 and the clamping plate 11 can be fixed by welding or by bolts. For example, the connecting plate 12 and the clamping plate 11 are fixed by welding, which is simple to operate and the connection is firm.

[0043] In order to improve the connection strength between the connecting plate 12 and the clamping plate 11, the clamping assembly 1 also includes a first reinforcing member 13. Multiple first reinforcing members 13 are arranged vertically between the two connecting plates 12, and the two ends of the first reinforcing members 13 are respectively fixedly connected to the two connecting plates 12. The external force on the connecting plate 12 can be transmitted to the first reinforcing member 13, reducing local stress and improving the overall structural strength of the clamping assembly 1.

[0044] The first reinforcing member 13 can be a plate or a rod. For example, the first reinforcing member 13 is plate-shaped and extends horizontally. The plate shape facilitates processing, and the horizontal extension of the first reinforcing member 13 saves vertical space.

[0045] This embodiment does not specifically limit the number of the first reinforcing members 13. The number of the first reinforcing members 13 can be set according to the load on the connecting plate 12. For example, see [link to example]. Figure 1 Three first reinforcing members 13 are provided between the two connecting plates 12, and the three first reinforcing members 13 are evenly spaced along the vertical direction.

[0046] In other embodiments, the connecting plate 12 is subjected to a large load, and five first reinforcing members 13 can be provided between the two connecting plates 12 to improve the structural stability of the connecting assembly.

[0047] In this embodiment, see Figure 1 and Figure 2 The clamping assembly 1 also includes two sets of second reinforcing members 14. Each set of second reinforcing members 14 is fixedly connected to the connecting plate 12 and the clamping plate 11, and is connected to the opposite side of the connecting plate 12. This further enhances the connection stability between the connecting plate 12 and the clamping plate 11. The second reinforcing members 14 and the first reinforcing members 13 are disposed on both sides of the connecting plate 12 to prevent deformation and displacement of the connecting plate 12 and improve the positional accuracy of the connecting plate 12.

[0048] The second reinforcing member 14 can be a rod or a plate. Exemplarily, each group of second reinforcing members 14 includes multiple reinforcing plates spaced apart vertically, the cross-sectional shape of which is triangular or trapezoidal. The plate-shaped second reinforcing member 14 provides better support for the connecting plate 12 and the clamping plate 11.

[0049] Specifically, the reinforcing plate has a triangular cross-sectional shape, and its two short sides are fixedly connected to the connecting plate 12 and the clamping plate 11, respectively. The stability of the connecting plate 12 and the clamping plate 11 is improved by utilizing the stability of the triangle.

[0050] Further, see Figure 2 The cross-section of the reinforcing plate is trapezoidal, which makes the edges smooth and avoids injuring construction workers.

[0051] The connecting screw 2 passes through the connecting hole 121 of the clamping plate 11, allowing the clamping assembly 1 to be connected end-to-end for easy fixation to the pier 100. This embodiment does not specifically limit the number and size of the connecting holes 121 on the clamping plate 11. For example, each connecting plate 12 has two connecting holes 121 spaced apart vertically, and the corresponding connecting holes 121 on the two connecting plates 12 on each clamping plate 11 are aligned horizontally. The horizontal alignment of the connecting holes 121 facilitates the insertion of the connecting screw 2. The two connecting screws 2 respectively pass through two sets of connecting holes 121, preventing the connecting plate 12 from twisting and improving accuracy.

[0052] Specifically, two horizontally extending connecting screws 2 are arranged vertically between two adjacent connecting plates 12, and the two connecting screws 2 are sequentially inserted into their corresponding connecting holes 121. The vertically spaced connecting holes 121 can reduce the horizontal space occupied and lower costs.

[0053] More specifically, the two ends of the connecting screw 2 are provided with external threads for screwing and locking the nut 3, while the rest is a smooth rod, which is easy to process and reduces costs.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
