Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and more specifically, it relates to a temporary consolidation structure for continuous beam bridge piers. Background Technology

[0002] Continuous beam structures are widely used in modern bridge construction. The zero block of a continuous beam, located at the top of the pier, is a crucial starting point for the entire continuous beam construction. Its construction quality and safety directly affect the construction of subsequent beam segments and the structural performance of the entire bridge.

[0003] Currently, common support methods often use a single zero-block to support the main structure. This approach can easily lead to uneven stress on the structure, affecting overall stability. Other technologies employ additional support devices, typically fitted over the piers. However, these devices are susceptible to sliding down the piers under adverse weather conditions or during long-term use. Once displacement occurs, the support device not only fails to effectively support the main structure but also exerts a downward pulling force, significantly hindering subsequent construction. Utility Model Content

[0004] This utility model provides a temporary fixed structure for a continuous beam bridge pier, which can support two sets of support components through two top support plates, thereby preventing the support components from sliding and ensuring the stable support of the support components for the main body.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A temporary fixed structure for a continuous beam bridge pier is provided, comprising a pier, two sets of support components, two sets of fixed columns, and two top support plates. The pier is arranged vertically, with a zero block at the upper end and a main body at the top of the zero block. The two sets of support components are symmetrically arranged on both sides of the pier, and are connected to the pier and the main body respectively. The two sets of fixed columns are arranged on both sides of the pier and correspond one-to-one with the two sets of support components. The fixed columns are located below the support components and extend horizontally outward. The two top support plates correspond one-to-one with the two sets of fixed columns, with the fixed columns penetrating the top support plates, which are used to support the support components.

[0006] In one possible implementation, the outer periphery of the fixing column is threaded with a first fixing nut located outside the top support plate.

[0007] In one possible implementation, two sets of support components are mounted on the piers by two clamping hoops, which are connected by connectors. The two clamping hoops are set one-to-one with the two sets of support components and are located above the top support plate.

[0008] In some embodiments, the support assembly includes a reinforcing member and two struts. The reinforcing member is disposed on the outer peripheral wall of the clamping hoop and extends outward. The two struts are respectively disposed on both sides of the main body, and the two ends of the struts are respectively connected to the main body and the reinforcing member.

[0009] In some embodiments, the reinforcement includes two extension arms and an angle steel. The two extension arms are connected to the outer peripheral wall of the clamping hoop and extend outward. The two extension arms are spaced apart in the circumferential direction of the clamping hoop. The angle steel is disposed between the two extension arms and near the outer end of the extension arms. The two ends of the angle steel are respectively connected to the two extension arms. The strut is connected to the angle steel.

[0010] In some embodiments, a screw extending outward is provided on the side wall of the main body. The screw penetrates the support rod radially and is rotatably engaged with the support rod. A second fixing nut located outside the support rod is threaded on the outer circumference of the screw. An angle steel is rotatably connected to the extension arm.

[0011] In some embodiments, the strut extends downward through the angle steel, and two locking nuts are threaded onto the outer periphery of the strut, with the two locking nuts located on the upper and lower sides of the angle steel, respectively.

[0012] In some embodiments, the angle steel is provided with a horizontally extending elongated hole, and the strut is provided through the elongated hole.

[0013] In some embodiments, mounting plates are provided at both ends of the angle steel, and the mounting plates are rotatably connected to the extension arm via a pivot.

[0014] In some embodiments, the pivot is disposed through the mounting plate and the extension arm, the inner end of the pivot is connected to a hexagonal head located inside the mounting plate, and the outer circumference of the pivot is threaded with a hexagonal nut located outside the extension arm.

[0015] The temporary fixed structure for continuous beam bridge piers provided in this embodiment, compared with the prior art, avoids the downward displacement of the support components by connecting the top support plate with the fixed column and cooperating with the two top support plates to support the two sets of support components, thus ensuring the stable support of the support components for the main body.

[0021] Please see Figures 1 to 3The temporary consolidation structure for continuous beam bridge piers provided by this utility model is described below. The temporary consolidation structure for continuous beam bridge piers includes a pier 10, two sets of support components 20, two sets of fixing columns 30, and two top support plates 40. The pier 10 is arranged vertically, with a zero block 11 at the upper end and a main body 12 at the top of the zero block 11. The two sets of support components 20 are symmetrically arranged on both sides of the pier 10, and are connected to the pier 10 and the main body 12 respectively. The two sets of fixing columns 30 are arranged on both sides of the pier 10 and correspond one-to-one with the two sets of support components 20. The fixing columns 30 are located below the support components 20 and extend horizontally outwards. The two top support plates 40 correspond one-to-one with the two sets of fixing columns 30, and the fixing columns 30 penetrate the top support plates 40, which are used to support the support components 20.

[0022] This application provides a temporary consolidation structure for a continuous beam bridge pier. In its actual use, it provides a basic framework for temporary consolidation. Through the combination of the pier 10, support component 20, fixed column 30 and top support plate 40, a stable structure is formed that can effectively transmit and resist unbalanced moments generated during construction.

[0023] Two sets of symmetrically arranged support components 20 and fixed columns 30 ensure that the force is evenly transmitted from the main body 12 to both sides of the pier 10, avoiding stress concentration and improving the stability and safety of the structure.

[0024] The support component 20 needs to be removed after construction. This design avoids permanent welding or casting with the pier 10 and the beam, making it easier to remove and reducing the impact on the permanent structure.

[0025] The fixed column 30 is embedded in the pier 10. The fixed column 30 is connected to the top support plate 40. The two top support plates 40 support the two sets of support components 20, which prevents the support components 20 from sliding and ensures the stable support of the support components 20 to the main body 12.

[0026] Compared with the prior art, the temporary fixed structure for continuous beam bridge piers provided in this embodiment, through the connection between the top support plate 40 and the fixed column 30, and the support of the two sets of support components 20 by the two top support plates 40, avoids the downward displacement of the support components 20 and ensures the stable support of the support components 20 for the main body 12.

[0027] In one possible implementation, the aforementioned fixed column 30 adopts, as shown in... Figure 1 and Figure 3 The structure shown is described in the following document. Figure 1 and Figure 3 The outer circumference of the fixed column 30 is threaded with a first fixing nut 31 located outside the top support plate 40.

[0028] Specifically, the first fixing nut 31 can firmly lock the top support plate 40 to the outer peripheral wall of the pier 10, preventing it from sliding or shifting under load, thus ensuring the reliability of the structure and its support.

[0029] Furthermore, the pier 10 is provided with several fixed columns 30 at intervals around its circumference, and each top support plate 40 has two corresponding fixed columns 30.

[0030] In one possible implementation, the aforementioned support component 20 adopts, as shown in... Figure 1 and Figure 3 The structure shown is described in the following document. Figure 1 and Figure 3 Two sets of support components 20 are set on the pier 10 by two clamping hoops 50. The two clamping hoops 50 are connected by connectors 51. The two clamping hoops 50 are set one-to-one with the two sets of support components 20 and are located above the top support plate 40.

[0031] Specifically, by clamping the clamp 50 onto the already formed bridge pier 10, the installation of the support component 20 and its subsequent disassembly are facilitated.

[0032] The clamping hoop 50 provides a robust and reliable mounting base and stress point for the support assembly 20.

[0033] The connector 51 connects the two clamping hoops 50 on both sides, enhancing the integrity and collaborative working ability of the two clamping hoops 50 and the entire temporary consolidation structure, so as to jointly resist the load.

[0034] In some embodiments, see Figure 1 and Figure 3 The support component 20 includes a reinforcing member 21 and two support rods 22. The reinforcing member 21 is disposed on the outer peripheral wall of the clamping hoop 50 and extends outward. The two support rods 22 are respectively disposed on both sides of the main body 12, and the two ends of the support rods 22 are respectively connected to the main body 12 and the reinforcing member 21.

[0035] Specifically, the reinforcement 21 distributes the concentrated force transmitted from the strut 22 to a larger area of ​​the clamping hoop 50, thus avoiding excessive local stress in the clamping hoop 50.

[0036] The reinforcement member 21 provides a common, robust lower connection point for the two struts 22.

[0037] The two struts 22, together with the main body 12 and the reinforcing members 21, form a stable triangular support structure with excellent mechanical properties, effectively resisting forces in all directions.

[0038] In some embodiments, see Figure 3The reinforcement component 21 includes two extension arms 211 and an angle steel 212. The two extension arms 211 are connected to the outer peripheral wall of the clamping hoop 50 and extend outward. The two extension arms 211 are spaced apart in the circumferential direction of the clamping hoop 50. The angle steel 212 is disposed between the two extension arms 211 and close to the outer end of the extension arms 211. The two ends of the angle steel 212 are respectively connected to the two extension arms 211. The support rod 22 is connected to the angle steel 212.

[0039] Specifically, the two extension arms 211 provide a wider support base, improving the stability of the support assembly 20 in the direction parallel to the pier 10 and preventing lateral overturning. The angle steel 212, as the main load-bearing component, has excellent bending and compressive strength, effectively transferring the force of the strut 22 to the two extension arms 211. This combined structure ensures strength while being relatively lightweight and easy to install.

[0040] In use, fix the two extension arms 211 to the clamping hoop 50. Connect the two ends of the angle steel 212 to the outer ends of the two extension arms 211 respectively. Connect the lower end of the support rod 22 to the angle steel 212.

[0041] In some embodiments, see Figure 1 and Figure 2 The main body 12 has a screw 60 extending outward on its side wall. The screw 60 radially penetrates the support rod 22 and is rotatably engaged with the support rod 22. The outer circumference of the screw 60 is threaded with a second fixing nut 61 located outside the support rod 22. The angle steel 212 is rotatably connected to the extension arm 211.

[0042] Specifically, the strut 22 is connected to the main body 12 via a screw 60 and a nut, and the angle steel 212 is rotatably connected to the extension arm 211, which allows the angle of the strut 22 to be adjusted within a certain range. This design can adapt to different beam sizes and construction errors, ensuring that the strut 22 can provide support at the optimal angle and improve stress efficiency.

[0043] The second fixing nut 61 can tightly lock the upper end of the support rod 22 to the screw 60 of the main body 12, forming a reliable hinge fixing point.

[0044] In some embodiments, see Figure 3 The strut 22 extends downward through the angle steel 212, and two locking nuts 70 are threaded on the outer circumference of the strut 22. The two locking nuts 70 are located on the upper and lower sides of the angle steel 212, respectively.

[0045] Specifically, the upper and lower locking nuts 70 can firmly clamp the angle steel 212 at a specific position on the support rod 22, which not only determines the final length of the support rod 22, but also prevents relative sliding between the angle steel 212 and the support rod 22 under load, ensuring effective force transmission.

[0046] In some embodiments, see Figure 3 An angle steel 212 is provided with a horizontally extending elongated hole 213, and a support rod 22 is provided through the elongated hole 213.

[0047] Specifically, the elongated hole 213 extends axially along the fixing post 30, facilitating installation. During installation, it works in conjunction with the second fixing nut 61 to tighten the support rod 22. The support rod 22 then moves appropriately within the elongated hole 213, ensuring it remains firmly against the side wall of the main body 12. For later disassembly, the second fixing nut 61 can be removed first, and the two locking nuts 70 loosened. The support rod 22 can then be slid away from the main body 12, allowing it to detach from the fixing post 30 and separating from the main body 12, thus improving disassembly efficiency.

[0048] In some embodiments, see Figure 3 Both ends of the angle steel 212 are provided with mounting plates 214, and the mounting plates 214 are rotatably connected to the extension arm 211 via a rotating shaft 80.

[0049] Specifically, the rotating joint between the angle steel 212 and the extension arm 211 is clearly realized through the connection of the pivot 80, which allows the angle steel 212 to rotate around the pivot 80, thereby adapting to the change of the angle of the strut 22, ensuring that the support system is subjected to force at the optimal angle, and avoiding the generation of additional bending moment.

[0050] In some embodiments, see Figure 3 The rotating shaft 80 passes through the mounting plate 214 and the extension arm 211. The inner end of the rotating shaft 80 is connected to a hexagonal head 81 located inside the mounting plate 214. The outer circumference of the rotating shaft 80 is threaded with a hexagonal nut 90 located outside the extension arm 211.

[0051] Specifically, the design of the hexagonal head 81 and hexagonal nut 90 allows for easy tightening of the shaft 80 from the outside using a standard wrench tool, making installation and disassembly very convenient.

[0052] After tightening the hex nut 90, the pivot 80 will not loosen or fall off, ensuring the reliability of the hinge joint while allowing rotation. After adjusting the angle of the support rod 22, the hex nut 90 can be tightened to lock the angle and ensure the stability of the support.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
