Description

Technical Field

[0001] This utility model relates to the field of steel box girder bridge technology, and in particular to a steel box girder bridge installation alignment control device. Background Technology

[0002] A steel box girder bridge typically consists of a box-section beam composed of a top slab, a bottom slab, and two side webs. Depending on the needs, the top and bottom slabs can be used for vehicles and pedestrians or bicycles, respectively. For example, the Vienna Imperial Bridge is a typical double-deck box girder bridge. Its internal clearance meets the requirements for vehicle clearance, with the upper deck for cars and the lower deck for subway traffic. The construction process of a steel box girder bridge includes preliminary preparation, installation, safety and quality control, and unloading and dismantling. During installation, it is necessary to ensure that all connections are firm and reliable, and to implement strict safety and quality control. In terms of maintenance, it is necessary to regularly inspect all components of the bridge to ensure that they are in good working order.

[0003] Meanwhile, without the support of modern precision equipment, construction workers need to rely on experience and simple tools to determine the position of each part of the bridge. This usually means that repeated measurements and corrections are required to ensure that each component can be accurately connected. Due to the lack of an efficient adjustment mechanism, any adjustment may have a ripple effect, requiring a reassessment of the position of other related components. This means that once adjustments begin, multiple positions may need to be checked and corrected, greatly extending the project cycle, and each adjustment may introduce new errors.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Among the currently discovered feasible technologies, the following are described:

[0022] Steel box girder bridges, with their unique structure—a box-section beam composed of a top plate, bottom plate, and two side webs—have become an important part of modern bridge design. This structure not only endows bridges with strong load-bearing capacity but also provides flexible space utilization solutions. For example, the Vienna Imperial Bridge is a typical example of a double-deck steel box girder bridge. It cleverly utilizes internal clearance to meet the needs of different modes of transportation: the upper level provides space for vehicular traffic, while the lower level is dedicated to subway use. This layout not only improves land utilization but also optimizes urban traffic flow, maximizing the use of limited urban space. Preliminary preparation is the foundational stage to ensure the smooth progress of the project. This includes detailed planning and design work, ensuring that every detail is carefully calculated and considered. Material procurement is also a crucial aspect of this stage, requiring the selection of high-quality steel and other building materials to guarantee the bridge's safety and durability. Furthermore, on-site preparation is equally critical, including clearing the construction site and setting up temporary facilities. More importantly, this stage requires a comprehensive risk assessment and environmental impact assessment to ensure that the construction process complies with all relevant regulations and minimizes the impact on the surrounding environment. Installation is the central link of the entire project, requiring precise techniques and methods to ensure that all parts are firmly and reliably connected. The transportation and hoisting of prefabricated components is one of the main tasks of this stage, ensuring that each component arrives at its designated location accurately. On-site assembly work requires extremely high precision and technical expertise; any minute error can affect the final bridge quality. To guarantee installation quality, safety regulations must be strictly followed, and comprehensive quality control measures must be implemented. Safety is always one of the most important considerations throughout the entire construction process. The construction unit must develop a detailed safety plan to ensure that all operations are carried out under control, thereby maximizing the safety of workers and the public. Simultaneously, rigorous quality inspections must be conducted at each construction stage to ensure that the final product meets design standards and technical specifications. This involves not only the safety of the physical structure but also the selection and use of materials and the execution of construction techniques.

[0023] Constructing a steel box girder bridge in a traditional construction environment lacking modern precision equipment presents an extremely challenging task for construction workers. Lacking advanced positioning and adjustment technologies, the construction team must rely on extensive experience and a few basic tools to determine the precise locations of various bridge components. This means that every step requires meticulous operation and repeated verification to ensure that all components are accurately aligned. First, in this environment, construction workers need to perform a large amount of manual measurement work. This includes not only accurately determining the dimensions and positions of the bridge's main structural components, such as the top slab, bottom slab, and side webs, but also considering the impact of environmental factors (such as temperature changes and wind speed) on these measurements. Because each measurement may contain slight errors, this process must be repeated multiple times until the most accurate data is obtained. This approach is not only time-consuming and labor-intensive but also significantly increases the overall time cost of the project. Second, due to the lack of efficient adjustment mechanisms, any minor adjustment can affect the balance and stability of the entire bridge structure. For example, when adjusting the height or angle of a specific part, it may be necessary to reassess and adjust the positions of other related components to ensure proper alignment. This means that once adjustments begin, they can trigger a chain reaction, forcing the construction team to inspect and correct multiple locations. Each such adjustment carries the risk of introducing new errors, bringing nearly completed work back to square one, or even rendering previous efforts futile. Furthermore, traditional construction methods suffer from uneven resource allocation. To ensure the quality of the final product, projects often require more manpower and time for repeated corrections, increasing labor costs and potentially creating additional financial pressure due to delays. Simultaneously, workers exposed to outdoor conditions for extended periods face greater safety risks, especially when performing high-precision tasks, where even minor errors can have serious consequences.

[0024] This device, by setting multiple sets of positioning holes at the center of the lower surface of the bridge beam and using a first cylinder that engages with them, can achieve precise adjustment and rapid positioning of the bridge position. This greatly reduces the need for manual measurement and correction, and improves installation accuracy. The center of the fixed frame surface is equipped with a fastening plate for quick replacement to proceed to the next step of work, allowing for rapid switching between different positions without the need for extensive preparation work, significantly improving work efficiency. The design of the second cylinder and its piston end adjustment plate allows for fine-tuning of angle and position as needed, reducing the need for repeated checks and corrections, making the entire adjustment process smoother and more efficient. With the power support provided by the first and second cylinders, combined with the real-time monitoring function of the sensing module, precise adjustments can be made to specific areas without interfering with other parts, thus avoiding the problem of a single adjustment causing a global change and reducing the introduction of new errors.

[0025] like Figure 1 - Figure 5 As shown, a steel box girder bridge installation alignment control device includes a support column 1, a mounting frame 2, a fixing plate 3, a sleeve 8, a friction plate 9, a fixing bracket 15, fixing screws 16, a buckle plate 17, a slot 18, and a locking plate 19. The support column 1 has a mounting frame 2 fixedly connected to its top. A fixing plate 3 is fixedly connected to the center of the upper surface of the mounting frame 2. Two sets of fixing brackets 15 are symmetrically installed on both sides of the fixing plate 3 for placing and adjusting the bridge position structure. Each fixing bracket 15 has a fixing screw 16 near the corner, which is threaded to the fixing plate 3 for easy removal after operation. A buckle plate 17 is fixedly connected to the center of the surface of the fixing bracket 15 for quick replacement for the next step. A sleeve 8 is fitted over the outside of the buckle plate 17. A friction plate 9 is located at the center of the top of the sleeve 8. A slot 18 is provided on the upper surface of the buckle plate 17 near the edge to prevent it from falling off during bridge angle adjustment. A locking plate 19 corresponding to the slot 18 is provided through the upper surface of the sleeve 8 near the edge.

[0026] The upper surface of the fixing plate 3 is provided with a beam bridge 4. Multiple sets of drainage channels 7 are symmetrically opened on both sides of the upper surface of the beam bridge 4 near the edge. By setting the drainage channels 7, the drainage performance of the bridge is effectively improved, and water accumulation is prevented from damaging the bridge structure. On both sides of the lower surface of the beam bridge 4, there are water outlet channels 21 corresponding to the drainage channels 7. A fastening groove 6 is opened at the center of the front end of the beam bridge 4. The design of the water outlet channel 21 ensures that the water flowing in from the drainage channel 7 can be discharged smoothly, while the fastening groove 6 provides convenience for the connection with other components. A fastening block 20 is opened at the center of the rear end of the beam bridge 4 to fasten and connect with the fastening groove 6 on other bridges. A connecting groove 22 is opened on the lower surface of the beam bridge 4 near the corner. The design of the fastening block 20 and the fastening groove 6 makes the connection between the bridges more stable, and the connecting groove 22 provides additional support points for adjustment and fixation.

[0027] The beam bridge 4, as the core load-bearing structure, is placed directly on the upper surface of the fixed plate 3. Multiple sets of drainage channels 7 are symmetrically opened on both sides of its upper surface near the edge line to quickly drain rainwater and other accumulated water, preventing water retention from damaging the bridge structure. The drainage channels 7 are located on both sides of the upper surface of the beam bridge 4 to guide and discharge accumulated water, ensuring that the bridge surface is dry and avoiding water damage to the bridge. The water outlet channel 21 is set on both sides of the lower surface of the beam bridge 4, corresponding to the drainage channel 7, to ensure that the water flowing in from the drainage channel 7 can be smoothly discharged to the outside of the bridge, further protecting the bridge structure from water erosion. The fastening groove 6 is located at the front center of the beam bridge 4, which facilitates connection with other components and provides a stable starting or ending position for the entire bridge structure. The fastening block 20 is located at the center of the rear end of the beam bridge 4 and is used to connect with the fastening slots 6 on other bridges. This design ensures a stable connection between adjacent bridges and enhances the continuity and stability of the overall structure. The connecting slot 22 is located on the lower surface of the beam bridge 4 near the corner. These slots provide additional support points for adjustment and fixing, allowing for fine-tuning as needed during installation to ensure that each part is precisely in place.

[0028] Please see Figure 1 - Figure 4 Multiple sets of positioning holes 23 are sequentially opened from left to right on the lower surface center of the beam bridge frame 4. The top surface of the sleeve frame 8 is provided with a first cylinder 10 that is engaged with the positioning holes 23. The cooperation between the positioning holes 23 and the first cylinder 10 enables precise control and rapid adjustment of the bridge position, thereby improving installation efficiency and accuracy.

[0029] A sensing module 14 is installed at the center of the upper surface of the frame 8. Two sets of second cylinders 11 are symmetrically installed on both sides of the sensing module 14. The sensing module 14 can monitor various parameters during the installation process in real time to ensure accurate operation. The second cylinders 11 provide necessary power support. An adjusting plate 12 is installed on the piston end of the second cylinder 11. The upper surface of the adjusting plate 12 is provided with a fixing block 13 that engages with the connecting groove 22. Through the adjusting plate 12 and the fixing block 13, the angle and position can be easily fine-tuned, enhancing the flexibility and adaptability of the device. Two sets of support plates 5 are symmetrically installed at both ends of the beam bridge frame 4. The support plates 5 increase the support force at both ends of the bridge and improve the stability and safety of the overall structure.

[0030] Multiple sets of positioning holes 23 are sequentially opened from left to right on the lower surface center of the bridge beam 4. These holes are used to engage with the first cylinder 10. By adjusting the docking of the first cylinder 10 with different positioning holes 23, precise control and rapid adjustment of the bridge position can be achieved, ensuring the accuracy of the bridge installation process. The first cylinder 10 provides the necessary power support, allowing the operator to adjust the position of the bridge beam 4 as needed. The sensing module 14 is located at the center of the upper surface of the sleeve 8 and is responsible for real-time monitoring of various parameters during the installation process. Two sets of second cylinders 11 are symmetrically installed on both sides of the sensing module 14. They not only provide additional power support, but also perform specific adjustment actions through the adjusting plate 12 at the piston end of their pistons. The adjusting plate 12 is installed on the piston end of the second cylinder 11. The plate is equipped with a fixing block 13. The adjusting plate 12 can move under the action of the second cylinder 11, thereby realizing the fine adjustment of the bridge angle and position. Two sets of support plates 5 are symmetrically installed at both ends of the bridge, increasing the support force at both ends of the bridge and improving the stability and safety of the overall structure.
