[0040] Reference Figures 1 to 5In order to solve the problem in the prior art that the installation position of the arch frame 3 of the arch bridge cannot be adjusted, resulting in a low overall installation fault tolerance, the present invention provides an arch frame displacement structure for arch bridge construction. The displacement structure is set between two bridge banks that need to be constructed, that is, the displacement structure is set between the first bridge bank 1 and the second bridge bank 5. The arch frame 3 body is set on the displacement structure, and then the arch frame 3 is moved and adjusted to the construction position between the first bridge bank 1 and the second bridge bank 5 by the displacement structure, so that the arch frame 3 can provide formwork support for the arch bridge construction. Specifically, the displacement structure includes: an arch frame 3, a construction platform 4 and two sets of side span displacement assemblies 2. The arch frame 3 is erected between the first bridge bank 1 and the second bridge bank 5, and the arch frame 3 is used to provide formwork support for the arch bridge construction. The construction platform 4 is set on one side of the first bridge bank 1 and the second bridge bank 5, and the construction platform 4 extends between the first bridge bank 1 and the second bridge bank 5 and is located in the middle of the arch frame 3. Two sets of side span displacement assemblies 2 are respectively disposed on either side of the arch frame 3, and two sets of side span displacement assemblies 2 are respectively disposed on the first and second bridge banks 1 and 5. The two sets of side span displacement assemblies 2 are used to integrally drive the arch frame 3 to move its position on the first and second bridge banks 1 and 5, thereby enabling the arch frame 3 to be moved to a construction position between the first and second bridge banks 1 and 5. In this embodiment, the prefabricated and assembled arch frame 3 can be moved and adjusted to a construction position between the first and second bridge banks 1 and 5 using the two sets of side span displacement assemblies 2, thereby adjusting the construction position of the arch frame 3 and facilitating subsequent fine-tuning of the arch formwork support position. This effectively addresses the prior art issue of the arch frame 3 being unable to adjust its installation position, resulting in a low overall installation tolerance.

[0041] Reference Figures 2 to 3In this embodiment, two sets of the side span displacement assemblies 2 are respectively arranged between the first bridge bank 1 and the second bridge bank 5, so that the arch frame 3 can be moved and adjusted to the construction position between the first bridge bank 1 and the second bridge bank 5 by the two sets of side span displacement assemblies 2. Here, in order to facilitate the description of the side span displacement assemblies 2, a set of side span displacement assemblies 2 is used as an example. Specifically, a set of the side span displacement assemblies 2 includes: a slide 21, a support plate 212, a mounting plate 211, and a pulling assembly. The slide 21 is arranged on the first bridge bank 1, and the slide 21 is located on one side of the arch frame 3. The slide 21 is provided with a slide (not shown in the figure). The sliding direction of the slide is perpendicular to the distance between the first bridge bank 1 and the second bridge bank 5, so that the arch frame 3 can be moved and adjusted to the construction position between the first bridge bank 1 and the second bridge bank 5 along the slide. The support plate 212 is arranged on the slide 21, and the support plate 212 is located on the slide, and the support plate 212 slides along the slide. The mounting plate 211 is disposed at a location away from the slideway on the support plate 212. A plurality of mounting slots 213 are provided on the mounting plate 211. The mounting plate 211 is connected to the arch frame 3 via the mounting slots 213 to drive the arch frame 3 to move along the slideway to a construction position between the first bridge bank 1 and the second bridge bank 5. The pulling assembly is disposed at one end of the slideway, one end of which is connected to the support plate 212. The pulling assembly is used to drive the support plate 212 to move within the slideway to drive the arch frame 3 to move along the slideway to a construction position between the first bridge bank 1 and the second bridge bank 5.

[0042] Reference Figure 3 and Figure 4 In this embodiment, the pulling assembly includes: an anchor block 22, a pulling member 221, and a connecting steel rope 222. The anchor block 22 is set on the slide 21. The anchor block 22 is located at a position where the slide 21 is away from the first bridge bank 1. The anchor block 22 is used to provide a moving fulcrum. One end of the pulling member 221 is connected to the anchor block 22, and the other end of the pulling member 221 is connected to the support plate 212 via a connecting steel rope 222. That is, the pulling member 221 is connected to the support plate 212 via the connecting steel rope 222, and the pulling member 221 pulls the connecting steel rope 222 to drive the arch frame 3 of the arch bridge to move along the slideway and adjust to the construction position between the first bridge bank 1 and the second bridge bank 5.

[0043] Similarly, the side span displacement assembly 2 provided at the second bridge bank 5 also includes: a slide 21, a support plate 212, a mounting plate 211, and a pulling assembly. The slide 21 is provided on the second bridge bank 5, and is located on one side of the arch frame 3. A slideway (not shown in the figure) is provided on the slide 21, and the sliding direction of the slideway is perpendicular to the direction between the first bridge bank 1 and the second bridge bank 5, so as to enable the arch frame 3 to be moved along the slideway and adjusted to the construction position between the first bridge bank 1 and the second bridge bank 5. The support plate 212 is provided on the slide 21, and the support plate 212 is located on the slideway, and the support plate 212 slides along the slideway. The mounting plate 211 is disposed at a position where the support plate 212 is away from the slide. The mounting plate 211 is provided with a plurality of mounting slots 213. The mounting plate 211 is connected to the arch frame 3 via the plurality of mounting slots 213 to enable the arch frame 3 to be moved along the slide to a construction position between the first bridge bank 1 and the second bridge bank 5. The pulling assembly is disposed at one end of the slide. One end of the pulling assembly is connected to the support plate 212. The pulling assembly is used to drive the support plate 212 to move within the slide to enable the arch frame 3 to be moved along the slide to a construction position between the first bridge bank 1 and the second bridge bank 5. Specifically, the pulling assembly on the second bridge bank 5 also includes an anchor block 22, a pulling member 221, and a connecting steel rope 222. The anchor block 22 is disposed on the slide 21. The anchor block 22 is located at a position where the slide 21 is away from the first bridge bank 1. The anchor block 22 is used to provide a fulcrum for movement. One end of the pulling member 221 is connected to the anchor block 22, and the other end is connected to the support plate 212 via a connecting steel rope 222. Specifically, by connecting the pulling member 221 to the support plate 212 via the connecting steel rope 222, the pulling member 221 pulls the connecting steel rope 222, thereby moving the arch frame 3 along the slideway to the construction position between the first bank 1 and the second bank 5. In this embodiment, the pulling member 221 is a hand chain hoist, an electric hoist, or a hydraulic telescopic structure.

[0044] In this embodiment, to meet the construction requirements of different bridge bank heights, the side span displacement assembly 2 can be integrally mounted on a support block 51, allowing the support block 51 to lift the arch frame 3 as a whole. Specifically, by installing a height-increasing support block 51 at the bottom of the side span displacement assembly 2, the arch frame 3 can meet both displacement requirements and arch bridge construction requirements.

[0045] In this embodiment, in order to ensure the displacement effect, butter or other lubricating oil can be applied to the slideway to make the side span displacement assembly 2 move more smoothly.

[0046] Reference Figure 5In this embodiment, in order to reduce the assembly time of the arch frame 3 of the arch bridge, the arch frame 3 is a prefabricated integrated structure, that is, the arch frame 3 can be directly produced and processed at a convenient construction location or in a factory. The arch frame 3 includes: multiple groups of arch frame structures, multiple groups of arch frame structures are arched to cooperate with the construction of the Bailey beam of the arch bridge, and multiple groups of arch frame structures are arranged parallel to each other between the first bridge bank 1 and the second bridge bank 5. In order to strengthen the overall support effect of the multiple groups of arch frame structures on the construction of the Bailey beam of the arch bridge, transverse connecting rods 36 are arranged between the multiple groups of arch frame structures. The transverse connecting rods 36 are used to cross-connect the multiple groups of arch frame structures to connect the multiple groups of arch frame structures as a whole. In order to facilitate the description of the multiple groups of arch frame structures, one arch frame structure is taken as an example. Specifically, one arch frame structure includes: multiple support frames 33, multiple reinforcement flower racks 34, two first support bodies 31 and two support 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 two of the 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 displacement assemblies 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.

[0047] Reference Figure 4 and Figure 5 In this embodiment, to ensure that the first support bodies 31 firmly connect the multiple arch structures to the side span displacement assembly 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, with the triangular ends of the second support body 311 respectively abutting 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, to facilitate separation of the second support body 311 from the first support body 31 and the support link 32.
