Description

Technical Field

[0001] The present invention relates to the technical field of steel bar connection and laying, and specifically to a steel bar connection structure and laying method applicable to the construction of high piers of bridges. Background Art

[0002] In the construction of high piers of bridges, especially in relatively high piers, steel bar cages are often used to enhance the weighing capacity and seismic resistance of the structure. The steel bar cage is mainly composed of a steel bar network, and concrete is filled to form a solid support structure. However, for relatively high piers, a single steel bar cage cannot meet the height requirement, so it is necessary to connect multiple steel bar cages together to form a relatively high overall steel bar cage to meet this height requirement.

[0003] Currently, for the connection of two steel bar cages, mainly a lifting device is used to lift a steel bar cage above another steel bar cage, and manual connection is carried out. During this process, the steel bar cage often shakes, and the steel bar cage is not a completely regular cylindrical shape, which makes it difficult for the main steel bars between the two steel bar cages to be completely aligned. Manual secondary hammering is required for alignment, which is rather troublesome and greatly slows down the laying efficiency of the steel bar cage. In addition, during the hammering process, it is easy to cause damage or even deformation of the steel bars, so that the local stress structure of the steel bar cage is changed, and the overall stability and bearing capacity of the steel bar cage are reduced.

[0004] Therefore, it is necessary to provide a steel bar connection structure applicable to the construction of high piers of bridges to solve the problems raised in the above background art. Summary of the Invention

[0027] Please refer to Figures 1 to 5 In an embodiment of the present invention, a steel bar connection structure applicable to the construction of high piers of bridges includes a support base 1, a support rod 2, an adjusting assembly 3, and a clamping assembly 4. Among them, a plurality of ring grooves 11 are uniformly arranged in a circumferential manner on the support base 1. A support rod 2 is slidably arranged in the ring groove 11 in a limited manner, and a spring 12 is arranged between the support rod 2 and the support base 1. An adjusting assembly 3 is slidably arranged on the support rod 2;

[0028] The adjusting assembly 3 includes a slide plate 31 and two adjusting rods 32. Among them, the slide plate 31 is slidably arranged on the support rod 2, and two adjusting rods 32 are arranged on the slide plate 31. The output ends of the two adjusting rods 32 and the slide plate 31 are respectively hinged and fixedly provided with a clamping assembly 4;

[0029] Two support plates 311 are vertically and fixedly arranged on the slide plate 31. Two fixed rods 312 are fixedly arranged in the vertical direction between the two support plates 311. A deflection groove 321 is formed on the adjusting rod 32. The fixed rod 312 is inserted into the deflection groove 321 and slides along the deflection groove 321. A first telescopic rod 313 is hinged between the slide plate 31 and the adjusting rod 32 at the bottom side. A second telescopic rod 314 is hinged between the first telescopic rod 313 and the slide plate 31;

[0030] The clamping assembly 4 includes a clamping seat 41, a clamping block 42, a clamping strip 43, and a driving member 44. Among them, the clamping block 42 is symmetrically and slidably arranged on the clamping seat 41. The clamping block 42 is in a semi-circular arc shape. A plurality of clamping strips 43 are slidably arranged in a circumferential manner in the clamping block 42. Driving members 44 for driving the clamping strips 43 to slide are rotatably arranged at both ends of the clamping block 42.

[0031] During implementation, the support base 1 together with the entire connection structure is lifted above the first steel reinforcement cage. Subsequently, multiple sliding plates 31 are driven to slide according to the positions of the main steel bars on the first steel reinforcement cage. At the same time, the support rod 2 offsets along the annular groove 11, so that the clamping assembly 4 at the output end of the sliding plate 31 is aligned with the main steel bars on the first steel reinforcement cage. Subsequently, the main steel bars on the first steel reinforcement cage are fixedly clamped by the clamping assembly 4, so that the connection structure as a whole is fixed to the first steel reinforcement cage. Then, the second steel reinforcement cage to be connected is lifted directly above the first steel reinforcement cage and the connection structure. Subsequently, the adjusting rod 32 is pulled to deflect and slide along the fixed rod 312 according to the positions of the main steel bars on the second steel reinforcement cage, so that the clamping assembly 4 provided at the output end of the second adjusting rod 32 is aligned with the main steel bars on the second steel reinforcement cage. And after alignment, during the process of clamping the main steel bars by the two clamping blocks 42 and the clamping strip 43 in the clamping assembly 4, the main steel bars on the second steel reinforcement cage can be driven to move to the middle position of the clamping assembly 4. Subsequently, the first expansion rods 313 and the second expansion rods 314 on the multiple sliding plates 31 are driven to expand and contract, so that the adjusting rod 32 drives the clamping assembly 4 and the main steel bars on the second steel reinforcement cage to move. That is, an initial expansion and contraction value is set for the first expansion rods 313 and the second expansion rods 314. When the first expansion rods 313 and the second expansion rods 314 are at this initial expansion and contraction value, the clamping assembly 4 on the adjusting rod 32 and the clamping assembly 4 on the sliding plate 31 are completely aligned in the vertical direction, and the distance between them is fixed. After the clamping assembly 4 on the adjusting rod 32 clamps and fixes the main steel bars on the second steel reinforcement cage, the expansion and contraction values of the first expansion rods 313 and the second expansion rods 314 are set to the initial set length, so as to align the main steel bars on the first steel reinforcement cage and the second steel reinforcement cage, thereby facilitating the connection of the two steel reinforcement cages, and the steel bars will not be damaged during the connection, further ensuring that the stress structure of the connected steel reinforcement cage will not change, and further ensuring that the stability and bearing capacity of the steel reinforcement cage will not be affected.

[0032] In this embodiment, as Figure 4 and Figure 5 , the driving member 44 includes two driving discs 441 and an arc-shaped plate 442 that fixedly connects the two driving discs 441. A plurality of inclined grooves 443 are circumferentially formed on the driving disc 441. Guide rods 431 are symmetrically arranged on the upper and lower sides of the clamping strip 43, and the guide rods 431 are inserted into the inclined grooves 443 and slide along the inclined grooves 443.

[0033] Arc-shaped hydraulic rods 444 are fixedly arranged on the arc-shaped plate 442. Arc-shaped guide bars 421 are fixedly arranged on the clamping blocks 42. An arc-shaped hydraulic cavity is formed in the arc-shaped guide bar 421, and the arc-shaped hydraulic rod 444 slides in a sealed manner along the arc-shaped hydraulic cavity;

[0034] A driving rod 411 is slidably arranged on the clamping seat 41 through hydraulic drive. T-shaped rods 412 are symmetrically and fixedly arranged on the driving rod 411. T-shaped grooves 422 are obliquely formed on the clamping blocks 42. The two T-shaped rods 412 are respectively inserted into the T-shaped grooves 422 in the two clamping blocks 42 and slide along the T-shaped grooves 422.

[0035] During implementation, the hydraulic pressure is used to drive the sliding of the driving rod 411, so that the driving rod 411 drives the two T-shaped rods 412 to slide. Further, the T-shaped rods 412 slide along the T-shaped grooves 422 on the two clamping blocks 42, so that the two clamping blocks 42 open or clamp. And during the sliding process, the two clamping blocks 42 always slide synchronously. Therefore, when clamping the main reinforcement, the main reinforcement can be driven to move to the middle position between the two clamping blocks 42. In addition, a plurality of clamping strips 43 are slidably arranged in the clamping blocks 42, so that the clamping blocks 42 can achieve variable-diameter clamping. That is, when encountering steel bars of different specifications, by applying hydraulic pressure to the arc-shaped hydraulic cavity, the arc-shaped hydraulic rod 444 slides. Further, the arc-shaped plate 442 drives the two driving discs 441 to slide. Further, the guide rod 431 slides along the inclined groove 443, so that the plurality of clamping strips 43 slide. Further, the clamping radius of the clamping blocks 42 is changed, and effective clamping of various steel bars of different specifications is further realized.

[0036] In this embodiment, two hinge seats 413 are fixedly arranged on one of the two clamping seats 41 hinged to the two adjusting rods 32. And the distance between the two hinge points on the two hinge seats 413 is equal to the distance between the two centers of the two fixed rods 312.

[0037] Particularly, for the convenience of understanding, the two adjusting rods 32, the clamping seat 41 and the support plate 311 can be regarded as a parallelogram. The four vertices of this quadrilateral are respectively the fixed points of the two fixed rods 312 and the hinge points of the two hinge seats 413. In this quadrilateral, since the positions of the fixed rods 312 are fixed, and the distance between the two hinge points on the two hinge seats 413 is equal to the distance between the two centers of the two fixed rods 312, it can be regarded that one side of this parallelogram is fixed, and the clamping seat 41 is the side parallel to the fixed side. Therefore, no matter how the other two sides change, that is, how the adjusting rods 32 slide and deflect, the clamping seat 41 always remains parallel to the support plate 311, that is, always remains in the vertical direction. Further, it is ensured that during the process of the adjusting rods 32 driving the clamping assembly 4 to move, the clamping assembly 4 itself will not deflect. Further, no matter how the clamping assembly 4 moves, it can clamp the main reinforcement in the vertical direction.

[0038] In this embodiment, two sealing cavities are formed in the sliding plate 31. Two sliding rods 21 are fixedly arranged on the support rod 2. The two sliding rods 21 are hermetically slid along the two sealing cavities respectively. Moreover, limiting support plates 22 are symmetrically and fixedly arranged on the support rod 2. Limiting sliding grooves are formed in the limiting support plates 22. The sliding plate 31 is clamped into the two limiting support plates 22 and slides along the limiting sliding grooves. That is, by changing the hydraulic pressure in the sealing cavities, the sliding of the sliding rods 21 can be realized, and further the sliding plate 31 can slide along the support rod 2.

[0039] A steel bar laying method applicable to the construction of high piers of bridges includes the following steps:

[0040] S1. Use a hoisting device to hoist the whole connecting structure above the first steel bar cage to be connected. Drive the sliding plate 31 to slide so that the clamping assembly 4 at the output end of the sliding plate 31 is fixedly connected to the main steel bars of the first steel bar cage, and the whole connecting structure is fixed on the first steel bar cage.

[0041] It should be noted that when making the steel bar cage, a circular tire mold is generally used. Although the steel bar cage is designed to be as close to a regular cylindrical shape as possible, due to errors and process limitations in the manufacturing process, the finished product may have certain shape deviations. Therefore, the sliding plate 31 is slidably arranged, and the support rod 2 can deflect along the support base 1, so that the plurality of clamping assemblies 4 can clamp all the main steel bars on the first steel bar cage and are not affected by the irregular shape.

[0042] S2. Use a hoisting device to hoist the second steel bar cage to be connected directly above the first steel bar cage. Then, pull the two adjusting rods 32 to rotate and slide along the fixed rod 312, so that the clamping assemblies 4 hinged to the two adjusting rods 32 are aligned with the main steel bars on the second steel bar cage, and use the clamping assemblies 4 to fixedly connect the main steel bars on the second steel bar cage to the adjusting rods 32. Correspondingly, the second steel bar cage is also an irregular cylindrical shape. Therefore, the two adjusting rods 32 are rotatably and slidably arranged on the fixed rod 312, so that the clamping assemblies 4 arranged at the output ends of the adjusting rods 32 can be adjusted arbitrarily in the horizontal and vertical directions, and further ensure that the clamping assemblies 4 on the adjusting rods 32 can clamp the main steel bars on the second steel bar cage.

[0043] S3. Drive the telescopic rods I 313 and telescopic rods II 314 on the plurality of sliding plates 31 to telescopically slide according to the positions of the main steel bars on the second steel bar cage, so that the adjusting rods 32 move in the horizontal and vertical directions, and the clamping assemblies 4 on the adjusting rods 32 are aligned with the clamping assemblies 4 on the sliding plates 31.

[0044] Specifically, the first telescopic rod 313 and the second telescopic rod 314 are hydraulic telescopic rods, and the two are divided into two modes: active telescoping and passive telescoping. When the clamping assembly 4 and the adjusting rod 32 are manually pulled to move, the first telescopic rod 313 and the second telescopic rod 314 are in the passive telescoping state. After the clamping assembly 4 fixes and clamps the main reinforcement, the first telescopic rod 313 and the second telescopic rod 314 are actively driven to telescope, causing the adjusting rod 32 to deflect and slide, thereby pulling the clamping assembly 4 and the main reinforcement to move;

[0045] S4. Fix and connect the two completely aligned steel reinforcement cages. At the same time, release the clamping assembly 4 and lift the entire connection structure above the second steel reinforcement cage again, and repeat this cycle to complete the laying work of the entire steel reinforcement cage.

[0046] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
