[0025] The following combines Figures 1 - 3 to describe the support and positioning device provided by the present utility model.

[0026] Figure 1 The structural schematic diagram of the support and positioning device provided by the embodiments of the present utility model is exemplified.

[0027] Referring to Figure 1 , a support and positioning device provided by the embodiments of the present utility model includes a support assembly 100 and a plurality of first limiting components 200. The support assembly 100 has an assembly surface, and the assembly surface is inclined to better adapt to the installation angle of the arch foot. The plurality of first limiting components 200 are used to limit the arch foot, and the plurality of first limiting components 200 are arranged at intervals on the support assembly 100 and are arranged at an angle with the assembly surface. In terms of material selection, the support assembly 100 should be made of high-strength materials, such as high-strength steel, to ensure sufficient load-bearing capacity and durability. The part of the first limiting component 200 in contact with the arch foot can adopt wear-resistant materials, such as stainless steel or cemented carbide, to reduce wear and extend the service life. Secondly, considering that the arch bridge may be in a harsh environment, all exposed materials should have good corrosion resistance, that is, galvanized steel or composite materials can be used, or the 100 can be cast with concrete.

[0028] In the above structure, the support component 100 provides a solid support for the installation of the arch springing, which helps to maintain the stability of the arch springing during the installation process and avoid position changes caused by external disturbances (such as wind force, vibration, etc.). Through the precise setting of the first limiting component 200, the installation accuracy of the arch springing can be greatly improved, and the position deviation caused by human operation errors can be reduced. The included angle design of the first limiting component 200 with the assembly surface can be adjusted according to the actual situation to enhance the adaptability of the present utility model and be applicable to different types of arch bridges and different construction site conditions. Through the preset support and limiting system in the embodiment of the present utility model, the installation process can be simplified, the installation difficulty can be reduced, and the work efficiency can be improved. Precise positioning can ensure good cooperation between the arch springing and other components, thus ensuring the quality and safety performance of the entire arch bridge structure.

[0029] In some possible embodiments, the support component 100 can be designed in a modular form, so that it can be flexibly combined according to different arch bridge designs and site conditions, which is convenient for transportation and rapid installation. Secondly, reinforcing ribs are added at the key parts of the support component 100 to improve the rigidity and stability of the overall structure. Reliable connection methods (such as welding, bolt connection) can also be used to ensure the firm connection between components, and at the same time, it is convenient for disassembly and maintenance. The first limiting components 200 should be evenly distributed to ensure that the arch springing receives balanced supporting forces and avoid deformation caused by excessive local stress. In order to adapt to different installation angles, the first limiting component 200 should be equipped with an adjustable included angle adjustment mechanism, so that the first limiting component 200 can adjust the included angle with the assembly surface according to actual needs.

[0030] Figure 2 The schematic structural diagram of the first limiting component of the support and positioning device provided by the embodiment of the present utility model is illustrated.

[0031] Refer to Figure 2 , in some embodiments of the present utility model, the first limiting component 200 includes a base 210, the base 210 is arranged on the support component 100, and the base 210 is provided with a limiting cylinder 220, and the limiting cylinder 220 is adapted to the arch springing.

[0032] Specifically, the base 210 can be designed into structures such as rectangular, square or oval to provide a larger supporting area and enhance stability. Reinforcing rib plates can also be arranged below the base 210 to increase the rigidity and bending resistance of the base 210. Holes can also be reserved on the base 210 to facilitate fixing it on the support component 100 through connecting pieces such as bolts. Of course, the connection between the base 210 and the support component 100 can also be in a welding manner.

[0033] The limiting cylinder 220 can adopt a cylindrical structural design, so that it can better fit the shape of the arch foot and provide uniform supporting force. For some occasions that require more precise adjustment, a conical or stepped design can also be adopted to facilitate fine-tuning the position of the arch foot. Of course, the limiting cylinder 220 can also be customized into a special shape to better match the contour of the arch foot. That is to say, the shape of the first limiting component 200 is not specifically limited and can be designed accordingly according to the specific shape of the arch foot. In some possible embodiments, positioning pins can also be arranged inside the limiting cylinder 220 to fix the arch foot and ensure that it will not move axially.

[0034] The first limiting component 200 can be designed to be split-type, that is, the limiting cylinder 220 and the base 210 are detachably connected, which is convenient for transportation and on-site assembly. Specifically, the base 210 and the limiting cylinder 220 can be connected by bolts. The limiting cylinder 220 and the base 210 can also be integrally formed, which can improve the integrity and strength of the structure. Specifically, the base 210 and the limiting cylinder 220 can be connected by integral forging or by welding.

[0035] Refer to Figure 2 , in some embodiments of the present utility model, the limiting cylinder 220 includes a limiting cylinder body 221, the limiting cylinder body 221 is arranged on the base 210, and a plurality of stiffening rib plates 222 are arranged between the limiting cylinder body 221 and the base 210. The plurality of stiffening rib plates 222 are centered on the limiting cylinder body 221 and are arranged outside the limiting cylinder body 221.

[0036] Specifically, the stiffening rib plates 222 can be designed to be straight strips and arranged along the connection surface between the limiting cylinder body 221 and the base 210 to increase the rigidity of the structure. In order to further improve the stability of the limiting cylinder body 221, the stiffening rib plates 222 can also be designed to be arc-shaped or wavy, so as to disperse stress. In addition, the stiffening rib plates 222 can also be designed to be grid-shaped, which not only increases the strength but also reduces the weight. The number of the stiffening rib plates 222 can be determined according to the size and load-bearing requirements of the limiting cylinder 220. For the material of the stiffening rib plates 222, high-strength materials can be selected to enhance their supporting effect.

[0037] In the above structure, the stiffening rib plate 222 can significantly improve the structural strength of the entire first limiting component 200 by forming an additional support structure between the limiting cylinder body 221 and the base 210. This helps to resist external loads, especially the horizontal thrust and forces in other directions generated during the installation of the arch springing. Secondly, the arrangement of the stiffening rib plate 222 makes it difficult for the limiting cylinder body 221 to bend or deform. Especially during the installation of the arch springing, it can maintain its shape and position unchanged, ensuring that the arch springing can be accurately installed at the predetermined position. Furthermore, when the arch springing is installed in place, concentrated loads may be generated. The stiffening rib plate 222 can disperse these concentrated loads to a wider area, thereby reducing the stress concentration phenomenon between the limiting cylinder body 221 and the base 210, and avoiding material fatigue or fracture.

[0038] Referring to Figure 2 , in some embodiments of the present utility model, a plurality of reinforcing wings 223 are arranged at intervals on the outer periphery of the limiting cylinder body 221, and the reinforcing wings 223 are used to reinforce the connection between the limiting cylinder body 221 and the cement casting.

[0039] Specifically, the reinforcing wing 223 can be designed in a flat plate shape. This shape is simple and easy to process, and can provide a large contact area, which is beneficial to enhancing the bonding force with the cement casting. In addition, the reinforcing wing 223 can be designed in a shape with serrations. The serrations can be embedded in the cement casting to increase the friction force and prevent the limiting cylinder body 221 from rotating or displacing. Furthermore, the reinforcing wing 223 can be designed in a grid shape, which can not only increase the contact area with the cement casting, but also reduce the weight of the reinforcing wing 223. The reinforcing wing 223 can be made of high-strength steel or composite materials to ensure its sufficient strength and durability. In order to enhance the bonding force between the reinforcing wing 223 and the cement casting, a treatment to increase the friction coefficient can be carried out, such as increasing the surface roughness, and providing protrusions or depressions on its surface.

[0040] The connection method between the reinforcing wing 223 and the limiting cylinder body 221 can be welding or riveting, etc. In addition, the reinforcing wing 223 and the limiting cylinder body 221 can also be designed to be integrally formed, and manufactured by casting or molding processes, which can improve the strength of the overall structure. In this embodiment, through the design of the reinforcing wing 223, the connection strength between the limiting cylinder body 221 and the cement casting is significantly enhanced, ensuring the stability of the arch springing after installation. Secondly, the design of the reinforcing wing 223 can also effectively prevent the limiting cylinder body 221 from rotating in the cement casting and ensure its fixed position.

[0041] Figure 3 Schematic diagram of the structure of the second limiting component of the support positioning device provided by the embodiment of the present utility model is illustrated.

[0042] Referring to Figure 3In some embodiments of the utility model, the support positioning device also includes a second limiting component 300, which is arranged on the support component 100 and is located between multiple first limiting components 200. The second limiting component 300 is used to limit the hinge shaft steel pipe. The second limiting component 300 includes a bottom plate 310 and a limiting groove 320. The bottom plate 310 is arranged on the assembly surface, and the limiting groove 320 is arranged on the side of the bottom plate 310 away from the assembly surface. It should be noted that the hinge shaft steel pipe is the intersection of the V-shaped column connected between the two arch seats. When fixing the arch seat, in addition to limiting the arch foot, the hinge shaft steel pipe also needs to be limited, because the two ends of the V-shaped column are hinged to the arch seat. When limiting it, the hinge shaft steel pipe can be limited first, and when the hinge shaft steel pipe is limited, the connection between the V-shaped column and the two arch seats can be adjusted.

[0043] During the specific installation, first fix the base plate 310 on the assembly surface of the support assembly 100 to ensure that the plane of the base plate 310 fits tightly with the assembly surface. Then install the limit groove 320 on the side of the base plate 310 away from the assembly surface. The position of the limit groove 320 needs to be precisely adjusted to ensure that the hinge shaft steel pipe can be correctly guided and fixed. The hinge shaft steel pipe is placed in the limit groove 320. The design of the limit groove 320 can ensure that the hinge shaft steel pipe will not deviate from the predetermined position during the installation process. Through the restraining effect of the limit groove 320, the hinge shaft steel pipe is accurately positioned and fixed at the specified position.

[0044] The embodiment of the utility model can effectively prevent the hinge shaft steel pipe from deflecting or shaking during the construction process by combining the limiting groove 320 with the bottom plate 310, thereby enhancing the stability and reliability of the entire structure. Secondly, the design of the second limiting assembly 300 makes the installation of the hinge shaft steel pipe simpler and faster, without the need for complicated measurements and adjustments, thereby improving the construction efficiency.

[0046] Specifically, it can be connected to the support assembly 100 through the connecting rod 312, and the connection method can be welding or bolt connection. The limiting groove body 321 is a semi-arc structure, and its opening is set upward, which is convenient for limiting the hinge shaft steel pipe.

[0047] Reference Figure 3, in some embodiments of the present utility model, the support assembly 100 includes several vertical support rods 110 and several horizontal support rods 120. The vertical support rods 110 and the horizontal support rods 120 are cross-connected to form a framework, the height of the framework gradually increases from one side to the other side, and a plurality of diagonal rods 130 are cross-arranged between the vertical support rods 110 and the horizontal support rods 120.

[0048] The framework formed by the cross-connection of the vertical support rods 110 and the horizontal support rods 120 may specifically be a right trapezoidal structure, and a slope is provided at its top, and this slope constitutes an assembly surface. Both the first limiting assembly 200 and the second limiting assembly 300 are arranged at an angle with the cover surface, which is convenient for installing the arch feet.
