Description

Technical Field

[0001] The utility model relates to the technical field of arch bridge construction, in particular to a Bailey beam arch frame integral displacement device and system for arch bridge construction. Background Art

[0002] Bailey beam arch frames, serving as the supporting formwork for arch bridge construction, are typically assembled on-site between the two bridge banks, based on actual construction requirements. Specifically, the arch frames are erected using a full-width Bailey beam support structure, ensuring the construction of the left and right spans of the side arch rings. This full-width Bailey beam arch frame consumes significant amounts of steel, Bailey beams, and other ancillary construction materials, as well as labor, ultimately leading to excessively high project costs. Furthermore, the need for on-site arch frame formwork assembly prolongs the construction period. Consequently, existing Bailey beam arch frames suffer from a long overall construction period and high costs. Utility Model Content

[0060] Reference Figure 6 and Figure 7In this embodiment, the mid-span transverse displacement structure is disposed on the mid-span construction platform 4. To facilitate displacement of the middle portion of the Bailey beam arch 3 and subsequent construction, the mid-span construction platform 4 can be configured as a T-shaped structure. The mid-span construction platform 4 is supported by an integral platform bracket and a platform surface, which will not be described in detail herein. The mid-span transverse displacement structure displaces the Bailey beam arch 3 to a construction position between the first bridge bank 1 and the second bridge bank 5 on the mid-span construction platform 4. Specifically, the mid-span transverse displacement structure includes: a plurality of support rods 41, two second slides 42, a plurality of locking blocks 43, a plurality of anchor rods 432, and two second pulling assemblies. The plurality of support rods 41 are symmetrically disposed on both sides of the mid-span construction platform 4, and are located between the first bridge bank 1 and the second bridge bank 5. The plurality of support rods 41 form supporting bodies on both sides of the mid-span construction platform 4, respectively, to facilitate the subsequent erection of the displacement structure. Two second slides 42 are respectively arranged on both sides of the mid-span construction platform 4. The two second slides 42 are respectively connected to the multiple support rods 41. The two second slides 42 are both provided with a second slide. The setting direction of the second slide is consistent with the setting direction of the first slide, that is, to achieve the purpose of driving the Bailey beam arch 3 to move along the second slide to the construction position between the first bridge bank 1 and the second bridge bank 5. Multiple locking blocks 43 are respectively arranged in the two second slides. One end of the locking block 43 is provided with a sliding block 431. The locking block 43 is slidably connected to the second slide through the sliding block 431. Multiple anchor rods 432 are perpendicularly arranged at the other end of the locking block 43.

The other end of the locking block 43 is connected to the support frame 33 of the Bailey beam arch 3 through the anchor rod 432. The two second pulling assemblies are symmetrically disposed on one end of the two second slides 42, respectively. The second pulling assemblies are located away from the first bank 1 and the second bank 5. One end of the second pulling assemblies is connected to the locking block 43. The pulling direction of the second pulling assemblies is consistent with the pulling direction of the first pulling assemblies, thereby enabling the Bailey beam arch 3 to move along the second slideway to the construction position between the first bank 1 and the second bank 5. In other words, in this embodiment, by disposing the second slides 42 on both sides of the mid-span construction platform 4, the second pulling assemblies move the locking block 43 within the second slideway of the second slideway 42 via the anchor rod 432, driving the Bailey beam arch 3 along the second slideway to the construction position between the first bank 1 and the second bank 5.

[0061] In this embodiment, the second pulling assembly includes: a second anchor block 44, a second pulling member 441, and a second connecting steel rope 442. The second anchor block 44 is disposed on the second slide 42, located away from the first bridge bank 1. The second anchor block 44 is used to provide a fulcrum for movement. One end of the second pulling member 441 is connected to the second anchor block 44, and the other end of the second pulling member 441 is connected to the locking block 43 via a second connecting steel rope 442. That is, the second pulling member 441 is connected to the locking block 43 via the second connecting steel rope 442, and the second pulling member 441 pulls the second connecting steel rope 442, thereby driving the Bailey beam arch 3 along the second slide to the construction position between the first bridge bank 1 and the second bridge bank 5. In this embodiment, the second pulling member 441 is a hand chain hoist, an electric hoist, or a hydraulic telescopic structure.

[0062] In this embodiment, in order to make the locking block 43 and the anchor rod 432 fit more closely to the arch of the Bailey beam arch frame 3, the locking block 43 is inclined on the side away from the second slide, and the locking block 43 is in contact with the arched inner wall of the Bailey beam arch frame 3 through the inclination, and the anchor rod 432 is connected to the locking block 43 at the inclined portion of the locking block 43.

[0063] In this embodiment, to facilitate the lifting and removal of the mid-span transverse structure and the Bailey beam arch 3, the mid-span transverse structure further comprises: a plurality of lifting members 411, each of which is disposed on the plurality of support rods 41. The lifting members 411 are positioned between the support rods 41 and the second slide 42. The lifting members 411 are used to integrally drive the support slide height of the second slide 42 and the locking block 43 to facilitate the subsequent lifting and removal of the mid-span transverse structure. In this embodiment, the lifting members 411 can be electrically, hydraulically, or pneumatically operated. That is, the lifting members 411 are any of an electric push rod, a hydraulic push rod, and a pneumatic push rod.

[0064] Reference Figure 6 and Figure 7In this embodiment, to prevent the sliding block 431 in the mid-span transverse movement structure from sliding out of the second slideway, a first limiting plate 421 and two second limiting plates 422 are provided on the second slideway 42. The first limiting plate 421 is provided at a position of the second slideway 42 away from the pulling assembly. The first limiting plate 421 is used to prevent the sliding block 431 from causing the locking block 43 to move out of the second slideway of the second slideway 42. The second limiting plates 422 are symmetrically provided on both sides of the second slideway. The two second limiting plates 422 are located on both sides of the second slideway. The second limiting plates 422 are used to prevent the sliding block 431 from causing the locking block 43 to move out of the second slideway of the second slideway from the side of the second slideway.

[0065] In this embodiment, in order to ensure the displacement effect, butter or other lubricating oil can be applied to the first slide and the second slide to achieve smoother movement of the side span transverse movement structure 2 and the middle span transverse movement structure.

[0066] In this embodiment, to meet the construction requirements of banks of varying heights, the side span transverse structure 2 can be integrally mounted on support blocks 51, allowing the support blocks 51 to lift the Bailey beam arch 3 as a whole. Specifically, by installing height-increasing support blocks 51 at the bottom of the side span transverse structure 2, the Bailey beam arch 3 can meet both displacement requirements and arch bridge construction requirements.

[0067] Reference Figure 8In this embodiment, to reduce assembly time for the Bailey beam arch 3, the Bailey beam arch 3 is a prefabricated, integrated structure. This means the Bailey beam arch 3 can be directly manufactured and processed at a convenient construction location or within a factory. In one feasible approach, the Bailey beam arch 3 is a layered, spliced ​​structure. Specifically, the Bailey beam arch 3 comprises multiple arched arch structures, each arched to support the construction of the Bailey beam of the arch bridge. The multiple arch structures are arranged parallel to each other between the first and second bridge banks 1 and 5. To enhance the overall support provided by the multiple arch structures for the construction of the Bailey beam of the arch bridge, transverse connecting rods 36 are provided between the multiple arch structures. These transverse connecting rods 36 are used to cross-connect the multiple arch structures, effectively connecting the multiple arch structures layer by layer. To facilitate the description of multiple arch structures, a single arch structure is used as an example. Specifically, the arch structure comprises multiple support frames 33, multiple reinforcement trellises 34, two first support bodies 31, and two supporting connecting rods 32. The support frame 33 is internally provided with a reinforcement frame 331, which is used to strengthen the overall construction support effect of the support frame 33. Multiple support frames 33 are spliced ​​and connected to each other, forming an arch. In order to increase the wind resistance of the arch structure, at least two wind cable tie points 35 are provided at the points where the multiple support frames 33 are spliced ​​together. The wind cable tie points 35 are used to connect wind-resistant cables. Multiple reinforced flower racks 34 are square frames and are set on the multiple support frames 33. The reinforced flower racks 34 are used to install and strengthen the bending points where the multiple support frames 33 are spliced ​​together to ensure the overall arch stability of the arch structure. The first support body 31 is V-shaped, and the two first support bodies 31 are respectively arranged on both sides of the arch structure formed by the mutual splicing of multiple support frames 33. The open end of the first support body 31 is connected to the support frame 33, and the two first support bodies 31 are respectively connected to the two mounting plates 211 in the two side span transverse structures 2 away from the open end (preferably, the first support body 31 is detachably connected to the mounting plate 211 through the mounting groove 213 away from the open end, so as to meet different construction requirements). The two support links 32 are symmetrically arranged on both sides of the arch formed by the mutual splicing of multiple support frames 33. The support links 32 are connected to the open ends of the first support body 31. The support links 32 and the first support body 31 form a triangular structure. The support links 32 are used to connect the first support body 31 with the multiple support frames 33.In this embodiment, an arch is formed by splicing a plurality of support frames 33 together, and then the arch is reinforced with a flower rack 34, a reinforcement frame 331, and a wind-resistant cable is connected at the cable tie point 35 to ensure the stability of the multiple groups of arch frame structures erected parallel to each other between the first bridge bank 1 and the second bridge bank 5. Then, the arch frame is connected as a whole through a transverse connecting rod 36 to strengthen the support stability of the multiple groups of arch frame structures as a whole.

[0068] Reference Figure 3 and Figure 4 In this embodiment, to ensure that the first support bodies 31 firmly connect the multiple arch structures to the side span transverse structure 2, a second support body 311 is provided inside each of the first support bodies 31. The second support body 311 is triangular in shape, and the triangular ends of the second support body 311 respectively abut against the first support body 31 and the support link 32. The second support bodies 311 are arranged parallel to each other inside the first support bodies 31. In this embodiment, to facilitate the recycling and reuse of the arch structure, the second support body 311 is composed of three support rods, which are rotatably connected to the first support body 31 and the support link 32, respectively, so as to facilitate the separation of the second support body 311 from the first support body 31 and the support link 32.

[0069] In a second aspect, the present invention further provides a Bailey beam arch frame 3 integral displacement system for arch bridge construction, wherein the displacement system adopts one of the above-mentioned Bailey beam arch frame 3 integral displacement devices for arch bridge construction, and the displacement system further comprises: a displacement control module and a distance measurement module. The displacement control module is used to control the pulling amount of the first pulling component and the second pulling component, as well as to control the lifting and lowering of the lifting member 411. That is, in a feasible embodiment, the pulling amount of the first pulling component and the second pulling component can be controlled by controlling hydraulic pressure, air pressure or electrical signals, or the pulling amount of the first pulling component and the second pulling component can be controlled manually. The distance measurement module is used to perform position calibration and calibration on each arch frame structure.

[0070] The displacement method of the Bailey beam arch frame 3 integral displacement device or the Bailey beam arch frame 3 integral displacement system for arch bridge construction includes:

[0071] Before the Bailey beam is cast, multiple sets of arch structures are assembled between the first bridge bank 1 and the second bridge bank 5 to form the Bailey beam arch frame 3 as a whole. After the Bailey beam arch frame 3 as a whole is moved to the construction positions of the first bridge bank 1 and the second bridge bank through the two sets of first pulling components and the second pulling components through the first slideway and the second slideway respectively, wind-resistant steel cables are installed at the wind cable tie points 35 of the Bailey beam arch frame 3 to connect the Bailey beam arch frame 3 with the first bridge bank 1 and the second bridge bank 5 as a whole, thus completing the overall connection between the Bailey beam arch frame 3 and the first bridge bank 1 and the second bridge bank 5 and the installation of the entire displacement device.

[0072] After the Bailey beam is cast, the wind-resistant steel cables are disconnected from the first and second banks 1 and 5. The two sets of first pulling assemblies are used to drive the side span legs of the Bailey beam arch 3 along the first slideway for overall movement. Simultaneously, the second pulling assemblies are used to drive the mid-span of the Bailey beam arch 3 along the second slideway for overall movement. This allows the Bailey beam arch 3 to be disassembled from the completed Bailey beam and separated from its mold, enabling the reuse of the Bailey beam arch 3 and the displacement device. In this embodiment, by moving the prefabricated Bailey beam arch 3 to the construction location between the first and second banks 1 and 5 via the two sets of side span and mid-span transverse structures, the arch bridge construction period is shortened. Furthermore, since on-site assembly is not required, the construction difficulty and cost are reduced. This effectively addresses the long construction period of the Bailey beam arch 3 in the prior art.

[0073] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
