Description

Technical Field

[0001] This invention relates to the field of modular bridge 3D modeling technology, and in particular to a modular bridge structure based on Bentley and its modeling method. Background Technology

[0002] Most bridges, due to their location and cost considerations, are not built using traditional high-strength steel-concrete structures, leaving them vulnerable to collapse during extreme weather events, potentially causing significant losses. To mitigate this risk, modular bridges that can be quickly assembled and disassembled have emerged. However, existing modular bridge structures suffer from the following problems: 1. The quick-release structure is not fast enough for disassembly and assembly.

[0003] 2. Existing technologies mostly rely on manual installation of bridge panels, which is time-consuming and labor-intensive. There is an urgent need to design a transmission component that works with wedge-shaped transmission blocks to achieve automatic installation of bridge panels.

[0004] 3. At the same time, manual work is required on the bridge deck during the disassembly and assembly process, which poses a significant safety hazard.

[0005] This patent provides a modular bridge modeling method based on Bentley to guide the construction of modular bridges that can be quickly assembled and disassembled, and enables secondary development on Bentley 3D design software, thereby solving the above-mentioned problems. Summary of the Invention

This modeling method employs a modular design; modular bridges built based on this method allow for rapid assembly and disassembly of components, have short installation cycles, and are stable and reliable. Furthermore, assembly and disassembly can be performed at only one end of the bridge, eliminating the need for manual work on the bridge deck and ensuring a high safety factor.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] Example 1 like Figures 1 to 9 The diagram shows a modular bridge built using Bentley's modular bridge modeling method and its software implementation in Bentley. The bridge includes a foundation 1, a base 2, columns 3, guide beam support seats 4, guide beams 5, a bridge deck 6, quick-release buckle components 7, and a transmission component 8. The foundation 1 is a cast-in-place concrete foundation. The base 2 is fixed to the top surface of the foundation 1 with bolts. The upper and lower ends of the columns 3 are fastened to the guide beam support seats 4 and the base 2 respectively using quick-release buckle components 7. The guide beams 5 are snapped onto the guide beam support seats 4. The bridge deck 6 is parallel to the two guide beams 5 along their length direction using quick-release buckle components 7. The transmission component 8 is installed on the guide beams 5 and located below the bridge deck 6, and is used to drive the bridge deck 6.

[0028] In this embodiment, the quick-release buckle assembly 7 includes a sliding base 701, a limiting rod 702, a first reset spring 703, a first baffle 704, a second baffle 705, a first wedge block 706, and a second wedge block 707. The first baffle 704 and the second baffle 705 are fixed parallel to each other at both ends of the sliding base 701. The first reset spring 703 is sleeved on the limiting rod 702. The first wedge block 706 is fixed to one end of the limiting rod 702. The first wedge block 706 cooperates with the first baffle 704 to limit the first reset spring 703. The second wedge block 707 is fixed on the cover plate of the base 2, the guide beam support 4, and the guide beam 5 and is positioned directly opposite the gap between the first wedge block 706 and the second baffle 705. The first baffle 704 has a through hole 9 for the limiting rod 702 to pass through. The first wedge block 706 is slidably connected to the sliding base 701. The quick-release buckle assembly 7 works by using wedge block 2 707 on the cover plate at the corresponding location, which cooperates with wedge block 1 706 and baffle 2 705 to push the limiting rod 702 forward, allowing the limiting rod 702 to insert into the limiting hole 11 at the corresponding location, thus achieving a quick snap-fit ​​connection. When the cover plate is removed, the limiting rod 702 moves backward under the push of the return spring 1 703, ending the snap-fit ​​connection.

[0029] In this embodiment, each column 3 includes three column units. The sliding base 701 and the guide beam support 4 are respectively provided with three sets of quick-release buckle assemblies 7 and positioning cylinders 10 inside the bottom surface. Each column unit is limited by a set of quick-release buckle assemblies 7 and positioning cylinders 10. The column unit passes through the cover plate of the base 2 and is inserted into the positioning cylinder 10. The positioning cylinder 10 and the end of the column unit are provided with limiting holes 11 for the insertion of the limiting rod 702.

[0030] In this embodiment, a set of quick-release buckle components 7 is provided on one side of the upper part of the guide beam support 4, and a limiting hole 11 is provided on the side of the guide beam 5 for inserting the limiting rod 702. On the other side of the upper part of the guide beam support 4, a protrusion 12 and a sliding groove 13 are provided for limiting the guide beam 5. A support roller 14 is installed in the sliding groove 13.

[0031] In this embodiment, the transmission assembly 8 includes a synchronous belt 801, a wedge-shaped transmission block 802, and a second support roller 803. The synchronous belt 801 is driven by a motor and is installed parallel to the inner side of the guide beam 5. The wedge-shaped transmission block 802 includes a connecting block 802a, a second return spring 802b, and a third wedge block 802c. The third wedge block 802c is located above the connecting block 802a and is connected to the connecting block 802a through the second return spring 802b. The connecting block 802a is fixedly connected to the synchronous belt 801. The bottom surface of the bridge deck 6 is provided with a wedge-shaped groove 15 that cooperates with the third wedge block 802c. The second support roller 803 is installed parallel to the synchronous belt and evenly on the guide beam 5. The edge of the bridge deck 6 rests on the second support roller 803. When wedge block 3 802c moves toward the wedge-shaped limiting inclined surface of wedge groove 15, wedge block 3 802c will be compressed downward; when wedge block 3 802c moves toward the wedge-shaped limiting non-inclined surface of wedge groove 15, wedge block 3 802c will be inserted into wedge groove 15, causing bridge deck 6 to move together.

[0032] In this embodiment, multiple sets of quick-release buckle assemblies 7 are arranged in parallel inside the top surface of the guide beam 5, and limiting holes 11 for inserting the limiting rod 702 are provided on both sides of the bridge deck 6.

[0033] In this embodiment, the bottom surfaces of the bridge deck 6 are engaged with the guide beam 5 on both sides and can slide along the guide beam 5.

[0034] In this embodiment, the top surfaces of the guide beam 5 and the bridge deck 6 are respectively symmetrically fixed with lifting lug 16 and lifting lug 2 17.

[0035] In this embodiment, the base 1 and the base 2 are provided with fixed ears 18 facing each other.

[0036] Example 2 The rapid installation process for this modular bridge is as follows: First, four concrete foundations 1 are poured in place. Then, the foundations 1 and base 2 are fixedly connected by bolts and fixing lugs 18. Next, the column units are connected by quick-release buckle assemblies 7. After the three column units are installed, the modular guide beam 5 is assembled. The cover plate on the guide beam support 4 is removed. Using a lifting device and the support rollers 14 installed on the guide beam support 4, the modular guide beam 5 is pushed in the sliding groove 13 on the guide beam support 4 until the guide beam 5 is pushed onto the other end of the guide beam support 4. Then, the cover plate of the guide beam support 4 is closed to achieve the snap-fit ​​between the guide beam 5 and the guide beam support 4. Another guide beam 5 is installed on the other two guide beam support seats 4 in the same way. The cover plate on the guide beam 5 is removed. The first bridge deck 6 is placed on the guide beam 5 using a lifting device, ensuring that the wedge-shaped groove 15 on the bottom surface of the bridge deck 6 engages with the wedge block 802c. Then, the bridge is transported forward to the other end via a synchronous belt 801 and stopped. This method is used to transport the subsequent nine bridge deck panels 6 sequentially (the bridge in this embodiment includes ten bridge deck panels 6). Finally, the cover plate on the guide beam 5 is placed on top, connecting all bridge deck panels 6 to the guide beam 5, thus completing the installation of the modular bridge. After further safety checks, it is put into use.

[0037] The rapid disassembly process of this modular bridge is as follows: First, remove the cover plate of guide beam 5 to release the snap-fit ​​connection between guide beam 5 and bridge deck 6. Then, use a lifting device to remove bridge deck 6 at one end of the bridge, and subsequently transport bridge deck 6 to one side of the bridge deck using synchronous belt 801 and remove bridge deck 6. Next, remove the upper cover plate of guide beam support 4 to release the snap-fit ​​connection between guide beam 5 and guide beam support 4. At the other end of the bridge, use a lifting device to drag guide beam 5 on guide beam support 4 to achieve the overall disassembly and assembly of guide beam 5. Immediately afterwards, remove the lower cover plate on guide beam support 4 to release the snap-fit ​​connection between guide beam support 4 and column unit, and complete the disassembly of guide beam support 4 using a lifting device. After removing the cover plate of base 2, release the snap-fit ​​installation between base 2 and all column units, then remove the column units. Finally, by unscrewing the bolts, release the connection between base 2 and foundation 1, thus completing the rapid disassembly of the modular bridge.

[0038] Example 3 The modeling method for modular bridge structures based on Bentley in this embodiment includes the following steps: Step 1: In Bentley software, use the Open Roads module to quickly model the road at the construction site, optimize the horizontal and vertical alignment and cross-sectional layout of the road, so that the model meets the requirements of the road environment for bridge construction, and output the Open Roads road model. Step 2: Using the Open Bridge Modeler module, the modular bridge structure is designed parametrically and modularly. First, the foundation, base, column, guide beam support seat, guide beam, bridge deck, quick-release buckle assembly, transmission assembly, through hole, positioning cylinder, limiting hole, protrusion, sliding groove, support roller one, wedge groove, lifting lug one, lifting lug two, and fixing lug are designed; separate parameter templates are created for each bridge structure. Step 3: Next, perform parametric and modular design on the substructures in the modular bridge structure, designing the sliding base, limiting rod, return spring one, baffle one, baffle two, wedge one, and wedge two in the quick-release buckle assembly; establish separate parameter templates for each structure in the quick-release buckle assembly; then, design the synchronous belt, wedge transmission block, connecting block, return spring two, wedge three, and support roller two in the transmission assembly; establish separate parameter templates for each structure in the transmission assembly. Step 4: Using the ProStructures module, based on the established parameter templates, the templates are spliced ​​together, and a complex structural parametric model of the modular bridge structure is quickly established according to the construction steps and the connection relationship of the structure. Step 5: Based on the stress analysis and dimensional design in the design phase, adjust and optimize the parameters of the parametric model of the complex structure, and output a three-dimensional digital model of the modular bridge structure. Step 6: Based on the output 3D digital model of the modular bridge structure, process and assemble each structural component. Based on the Open Roads road model, carry out on-site construction of the modular bridge structure on the construction road.
