Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a lightweight combined fine-tuning support structure. Background Technology

[0002] When bridge structures are constructed using methods such as jacking, sliding, or moving, precise adjustments to the bridge structure's position are required before the installation of bridge bearings to meet installation accuracy requirements. Reliable support is needed for the fine-tuning jacks during bridge fine-tuning. Erecting fine-tuning supports that meet the support requirements of the fine-tuning process is a key technical problem that needs to be solved in this type of construction. Existing technologies generally require the erection of multiple rows of supports to provide reliable support. High foundation bearing capacity is required, and construction is difficult when the foundation cap size is small.

[0003] Patent CN202010777944.5 discloses an active jacking auxiliary support construction system for the lower chord arch of a beam-arch composite rigid frame, including a base support system, a support system, and a jacking system. The base support system includes a structure connecting the root of the lower chord arch to the pier and a triangular bracket structure providing bottom support for the steel pipe columns near segment #1. The support system includes steel pipe columns and lateral and transverse supports to prevent instability of the steel pipe columns, and a distribution beam located at segment #1 on top of the steel pipe columns. The jacking system includes an active jacking device for hydraulic jacks installed at the bottom of the steel pipe columns and a connection structure between the hydraulic jacks and the triangular bracket. However, the structure is relatively complex, the construction is difficult, and it occupies a large amount of space. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide a lightweight combined fine-tuning support structure with strong spatial adaptability, structural stability, lightweight design, and improved construction efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] This utility model provides a lightweight combined fine-tuning support structure, including: a support column, a horizontal connecting rod, a support beam, and a horizontal beam;

[0007] The supporting columns are arranged on the bridge abutment in a combination of upright and inclined configurations, reducing the support range at the bottom of the supporting columns and adapting to the limitations of the small size of the bridge abutment. The supporting beams are set on top of the supporting columns to provide support for the three-way jacks. A horizontal beam is set between the supporting beams of the two sets of supporting columns to form an inverted triangular support system. An auxiliary supporting column and an auxiliary supporting connecting rod are set in the middle of the horizontal beam to provide auxiliary support and anchoring for the horizontal beam, ensuring the reliability of the transverse bridge constraint of the support structure.

[0008] The supporting columns, horizontal connecting rods, supporting beams, and horizontal beams together constitute a lightweight combined support structure, providing reliable support for the fine-tuning of steel beams under space-constrained conditions.

[0009] Furthermore, the bridge abutment is provided with connecting embedded parts, and the supporting column is fixedly connected to the bridge abutment through the connecting embedded parts.

[0010] Furthermore, a horizontal connecting rod is provided in the middle of the support column to improve the stability of the support column.

[0011] Furthermore, a support pad is provided on the top surface of the support beam.

[0012] Furthermore, the top of the support pad is equipped with a limiting thrust plate for placing a three-way jack. This allows for precise adjustment of the steel beam's position.

[0013] Furthermore, a wall-supporting unit is provided between the supporting column and the pier to improve the longitudinal stability of the support structure.

[0014] Furthermore, the wall support unit includes a top wall support and a hinged wall support.

[0015] Furthermore, when the transverse dimensions of the bridge abutment are insufficient, auxiliary support blocks for abutment expansion are added at the edge of the bridge abutment to provide support for the bottom of the support columns.

[0016] Furthermore, the auxiliary support column and the auxiliary support connecting rod constitute an intermediate auxiliary support, providing lateral bridge constraint for the horizontal beam.

[0017] Furthermore, the horizontal beam connects the support beams of the left and right sets of support columns, providing a horizontal constraint in the transverse direction between the triangular supports.

[0018] 1. Preliminary preparation stage

[0019] Measurements are taken on the bridge abutment to determine the installation positions of the support columns, and connecting parts are pre-embedded. Based on the abutment dimensions and bridge structural characteristics, it is determined whether additional abutment enlargement auxiliary support blocks are needed.

[0020] 2. Bracket Installation Stage

[0021] The supporting columns are fixed to the bridge abutment through connecting embedded parts, and are arranged in a combination of upright and inclined methods to reduce the support range at the bottom of the columns.

[0022] Install horizontal connecting rods between the columns to improve their stability.

[0023] A support beam is installed at the top of the column to provide a support platform for the subsequent beam adjustment jacks.

[0024] A horizontal beam is installed between the support beams of the two sets of support columns on the left and right sides to form an inverted triangular support system.

[0025] Install auxiliary support columns and auxiliary support connecting rods at corresponding positions in the middle of the horizontal beam to provide auxiliary support and anchorage for the horizontal beam.

[0026] 3. Support System Improvement Phase

[0027] Install support pads on the top surface of the support beam, and set a limit thrust plate on the top of the pads.

[0028] In the longitudinal direction of the bridge, top buttresses and hinged buttresses are installed between the supporting columns and piers to improve the longitudinal stability of the columns.

[0029] Place a three-way jack on the limit thrust plate and adjust the position of the jack to match the contact surface of the steel beam, ensuring that the jack can make precise three-way adjustments to the steel beam.

[0030] 5. Steel beam fine-tuning stage

[0031] The three-way jacks were activated to make fine adjustments to the steel beam in the vertical, horizontal, and longitudinal directions.

[0032] The positional changes of the steel beams are monitored in real time by monitoring equipment to ensure that the adjustment accuracy meets the design requirements.

[0033] During the adjustment process, the support system provides stable support through its inverted triangular structure and horizontal beams, ensuring the stability of the adjustment process.

[0034] 6. Adjustment Completion Phase

[0035] After the steel beam is precisely positioned, lock the jack position.

[0036] To carry out the installation and fixing of bridge bearings.

[0037] Gradually release the load from the jacks and transfer the load to the permanent supports.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] (1) Strong spatial adaptability. The combination of upright and inclined support column arrangement significantly reduces the support range at the bottom of the columns, effectively solving the problem of bracket installation under small-sized platform conditions. Compared with the traditional two-row multi-steel pipe bracket structure, this utility model shows excellent adaptability under space-constrained conditions.

[0040] (2) Structural stability. The inverted triangular support system, combined with the intermediate auxiliary support structure, provides reliable lateral bridge constraint, solving the problem of insufficient lateral stability of traditional supports. Multiple stabilization measures, including horizontal connecting rods and wall-mounted components, ensure the safety performance of the support under various working conditions.

[0041] (3) Lightweight design improves construction efficiency. The modular lightweight design reduces the input of temporary structural materials and lowers construction energy consumption compared to traditional support structures. The modular design facilitates rapid on-site assembly and disassembly, improving construction efficiency and shortening the construction period. Attached Figure Description
