Description

Technical Field

[0001] This utility model relates to the field of bridge pier technology, specifically to a combined bridge pier steel cage and auxiliary installation platform. Background Technology

[0002] Bridge piers are an important component of bridge engineering, playing a crucial supporting role in the bridge structural system. In a bridge structure, piers are located between adjacent spans, transferring the loads from the bridge superstructure to the vertical load-bearing structure of the foundation. Piers can be classified according to their structural form into solid piers, hollow piers, and column-frame pile piers, etc. Different types are suitable for different engineering environments and construction needs, and their design and construction quality directly affect the safety and durability of the bridge.

[0003] As the skeleton of the bridge pier, the steel reinforcement cage plays a crucial role in enhancing the load-bearing capacity of the bridge pier. Traditionally, the steel reinforcement cages at both ends of the bridge pier are connected by simple alignment welding or sleeve connection. These two connection methods cause stress to concentrate at the connection points when the steel reinforcement cage is under load, resulting in poor overall structural stability of the steel reinforcement cage and difficulty in effectively coping with complex geological conditions and load changes. Based on this, a combined bridge pier steel reinforcement cage and auxiliary installation platform are proposed to solve the above problems. Utility Model Content

[0004] Based on the above description, this utility model provides a combined bridge pier reinforcement cage and auxiliary installation platform to solve the problem that simple alignment welding or sleeve connection methods cause stress to easily concentrate at the connection parts when the reinforcement cage is under force, resulting in poor overall structural stability of the reinforcement cage and difficulty in effectively coping with complex geological conditions and load changes.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a combined bridge pier steel cage, including an upper steel cage and a lower steel cage;

[0006] The upper and lower steel cages are staggered on opposite sides. A connecting mechanism is provided at the top between the vertical bars of two adjacent lower steel cages to facilitate the connection of the upper and lower steel cages. A reinforcing member is provided at the bottom of the outer surface of the lower steel cage to prevent deformation of the lower steel cage.

[0007] The connecting mechanism includes a sleeve welded to the top between two adjacent lower steel cage vertical bars, a serrated ring fixed to the bottom of the upper steel cage vertical bar, an installation ring threaded to the lower steel cage vertical bar, a limiting plate fixed to the installation ring, and a spiral groove opened on the opposite side of two adjacent limiting plates.

[0008] The sleeve is a hollow annular body.

[0009] Through the above technical solution, the upper and lower steel cages are staggered and fixed on opposite sides, which changes the stress concentration situation when the traditional aligned connection is used. This prevents all steel bars from breaking at the same cross section, and allows the force on the upper and lower steel cages to be transmitted and dispersed more evenly. This effectively improves the stability of the overall steel cage structure and enhances its ability to cope with complex geological conditions and load changes.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the bottom of the lower steel cage is trumpet-shaped, and the angle between the bottom of the vertical bars of the lower steel cage and the axis is 10°~15°.

[0012] The above technical solutions can increase the stress-bearing area, reduce the risk of settlement, and further prevent the steel bars from deforming.

[0013] Furthermore, the bottom of the upper steel cage is provided with external threads and is threadedly connected to the sleeve, and the outer diameter of the serrated ring is larger than the inner diameter of the sleeve.

[0014] The above technical solution can initially fix the upper and lower steel cages together with a sleeve, and the serrated ring can limit the length of the upper steel cage extending into the sleeve.

[0015] Furthermore, both sides of the limiting plate are curved surfaces, and the bottom of the upper steel cage vertical bar is threadedly connected to the spiral groove.

[0016] The above technical solution allows the setting of the limiting plate and spiral groove to further position the upper steel cage.

[0017] Furthermore, the reinforcing member includes a plurality of annular stirrups fixed to the bottom of the outer surface of the lower reinforcing cage, and a circular steel plate fixed to the bottom of the inner cavity of the lower reinforcing cage.

[0018] The above technical solutions can enhance the rigidity of the bottom of the lower steel cage and effectively prevent deformation of the lower steel cage.

[0019] Furthermore, the spacing between two adjacent annular stirrups is 50~100mm, and the thickness of the circular steel plate is 5~10mm.

[0020] Through the above technical solution, the circular steel plate at the bottom of the reinforcing cage can disperse and transmit the pressure from above, reduce local stress concentration, and thus enhance the overall load-bearing capacity of the reinforcing cage.

[0021] An auxiliary installation platform for a combined bridge pier reinforcement cage includes four arc-shaped support plates disposed on the outer sides of the upper and lower reinforcement cages; a connector is provided between two adjacent arc-shaped support plates, and the number of connectors is four. The four connectors and the four arc-shaped support plates are combined to complete a closed-loop assembly. Multiple support components are provided on the outer sides of both the upper and lower reinforcement cages.

[0022] The above technical solution, with the installation platform consisting of four arc-shaped support plates spliced ​​together, facilitates rapid construction of the installation platform, thereby improving the convenience of installing the steel cage.

[0023] Furthermore, each of the four arc-shaped support plates has a protrusion on one adjacent side, and two adjacent protrusions are connected by high-strength bolts.

[0024] Each of the four arc-shaped support plates is equipped with a guardrail on both the left and right sides, and the surface of the arc-shaped support plates is provided with anti-slip texture.

[0025] Through the above technical solution, the four arc-shaped support plates are designed to be connected by splicing, which facilitates the quick fixing of the installation platform and the steel cage, thus improving installation efficiency. The guardrails are used to protect the edges of the arc-shaped support plates to prevent workers from falling off them, and the anti-slip texture increases the friction between the feet and the arc-shaped support plates.

[0026] Furthermore, the support assembly includes multiple U-shaped clamps disposed on the outside of the upper and lower reinforcing cages, multiple vertical rods disposed on the left and right sides of the arc-shaped support plate, and a load-bearing plate fixed between the two vertical rods at the left and right ends and located on the lower side of the arc-shaped support plate; the side of the U-shaped clamps closest to the arc-shaped support plate is fixed to the vertical rods.

[0027] Through the above technical solution, the structure has strong overall stability and load-bearing capacity through the fixing of U-shaped clamps and vertical rods. The design of multiple load-bearing plates and multiple vertical rods can effectively distribute and bear the load.

[0028] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0029] 1. The upper and lower steel cages are staggered and fixed on opposite sides, which changes the stress concentration situation when the traditional aligned connection is used. This prevents all steel bars from breaking at the same cross section, and allows the stress on the upper and lower steel cages to be transmitted and distributed more evenly. This effectively improves the stability of the overall steel cage structure and enhances its ability to cope with complex geological conditions and load changes. The reinforcing members can enhance the rigidity of the bottom of the lower steel cage and effectively prevent the lower steel cage from deforming.

[0030] 2. The installation platform is composed of four arc-shaped support plates, which facilitates quick and easy assembly, thereby improving the convenience of installing the steel cage and making it easier to transport, thus reducing time costs. Attached Figure Description

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0045] Example: Reference Figure 1 A composite bridge pier reinforcement cage includes an upper reinforcement cage 1 and a lower reinforcement cage 2; the upper reinforcement cage 1 and the lower reinforcement cage 2 are staggered on opposite sides, and a connecting mechanism 3 is provided at the top between the vertical bars of two adjacent lower reinforcement cages 2 to facilitate the connection of the upper reinforcement cage 1 and the lower reinforcement cage 2; a reinforcing member 4 is provided at the bottom of the outer surface of the lower reinforcement cage 2 to prevent deformation of the lower reinforcement cage 2.

[0046] The bottom of the lower steel cage 2 is trumpet-shaped, and the angle between the bottom of the vertical bar of the lower steel cage 2 and the axis is 10°~15°, which can distribute the force on the lower steel cage 2, prevent the steel bars from deforming, and protect the service life.

[0047] refer to Figure 2 and Figure 3 The connecting mechanism 3 includes a sleeve 31 welded to the top between the vertical bars of two adjacent lower steel cages 2, a serrated ring 32 fixed to the bottom of the vertical bar of the upper steel cage 1, an installation ring 33 threadedly connected to the vertical bar of the lower steel cage 2, a limiting plate 34 fixed to the installation ring 33, and a spiral groove 35 opened on the opposite side of the two adjacent limiting plates 34; the sleeve 31 is an annular body with a hollow interior.

[0048] The bottom of the upper steel cage 1 is provided with external threads and is threadedly connected to the sleeve 31. The outer diameter of the serrated ring 32 is larger than the inner diameter of the sleeve 31. Both sides of the limiting plate 34 are arc surfaces. The bottom of the vertical bar of the upper steel cage 1 is threadedly connected to the spiral groove 35, which can reposition the vertical bar of the upper steel cage 1 that extends into the sleeve 31, thereby improving the connection accuracy between the upper steel cage 1 and the lower steel cage 2.

[0049] In use, the top of each vertical bar of the lower steel cage 2 is screwed into the mounting ring 33. The mounting ring 33 moves downward on the vertical bar and drives the limiting plate 34 to move downward. Then, a sleeve 31 is welded between the tops of two adjacent vertical bars of the lower steel cage 2. Then, a serrated ring 32 is welded above the external thread at the bottom of the vertical bar of the upper steel cage 1. Then, each vertical bar in the upper steel cage 1 is aligned with each sleeve 31. Then, multiple vertical bars are screwed into the sleeve 31 in sequence and the multiple vertical bars are hoisted together to form the upper steel cage 1 until the serrated ring 32 is in contact with the sleeve 31. The bottoms of multiple vertical bars of the upper steel cage 1 are respectively screwed into the spiral groove 35 between two adjacent limiting plates 34, so that the upper steel cage 1 and the lower steel cage 2 can be initially fixed.

[0051] The spacing between two adjacent annular stirrups 41 is 50~100mm, and the thickness of the circular steel plate 42 is 5~10mm. Dense annular stirrups 41 are added at the bottom of the lower steel cage 2. The dense annular stirrups 41 at the bottom can enhance the local strength and rigidity of the bottom of the lower steel cage 2, so that it remains stable during the concrete pouring process and avoids deformation. A circular steel plate 42 is welded to the bottom of the inner cavity of the lower steel cage 2. The circular steel plate 42 can provide additional support to prevent the lower steel cage 2 from deforming or twisting. The circular steel plate 42 can share the force with the lower steel cage 2, which can disperse and transmit the pressure from above, reduce local stress concentration, and improve the load-bearing capacity of the steel cage.

The four connectors and the four arc-shaped support plates are combined to complete a closed-loop assembly. Multiple support components 6 are provided on the outside of both the upper steel cage 1 and the lower steel cage 2.

[0053] It should be noted that the four curved support plates are spliced ​​together, which makes it easier for workers to transport and install them, reducing the complexity and time cost of on-site construction.

[0054] Each of the four arc-shaped support plates 5 has a protrusion on one side of each adjacent plate, and the two adjacent protrusions are connected by high-strength bolts. Guardrails are installed on both the left and right sides of the four arc-shaped support plates 5, and the surface of the arc-shaped support plates 5 is provided with anti-slip texture. The guardrails can provide protection for the workers on the arc-shaped support plates 5, and the anti-slip texture can increase the friction between the workers and the arc-shaped support plates 5, prevent the workers' feet from slipping, and greatly improve safety.

[0055] In addition, the support assembly 6 includes multiple U-shaped clamps 61 set on the outside of the upper steel cage 1 and the lower steel cage 2, multiple vertical rods 62 set on the left and right sides of the arc-shaped support plate 5, and a load-bearing plate 63 fixed between the two vertical rods 62 at the left and right ends and located on the lower side of the arc-shaped support plate 5; the side of the U-shaped clamps 61 closest to the arc-shaped support plate 5 is fixed to the vertical rods 62.
