Description

Technical Field

[0001] This utility model relates to the field of arch bridge pier and arch ring reinforcement, specifically a highly efficient reinforcement connection structure for the pier and arch ring of a cross-river arch bridge. Background Technology

[0002] Bridge piers mainly consist of a cap and a body. In bridges with two or more spans, excluding the abutments connecting to the embankment at both ends, the piers are the intermediate supporting structures. Piers are classified as solid piers, column piers, and frame piers, among others. Based on their plan shape, they can be divided into rectangular piers, pointed piers, and circular piers. Materials used for constructing bridge piers include wood, stone, brick, concrete, and reinforced concrete. The arch, also known as the main arch, is the primary load-bearing component of an arch bridge, bearing all the loads transmitted from the bridge and transferring them to the piers and foundations. The main cross-sectional forms include box girder, ribbed girder, and hyperbolic arch. Materials used include masonry, reinforced concrete, and steel. To improve the connection stability, a highly efficient reinforcement and connection structure is required. The "Arch Bridge Reinforcement Structure" disclosed in application number "202122460613.1" is an increasingly mature technology. This invention uses corrugated steel plates connected to form an arch body with the same shape as the arch ring but a slightly smaller diameter, possessing excellent mechanical properties and good support performance. Simultaneously, the flanged fixing structure of this invention connects to the bridge body, limiting the outflow of cement mortar from the filling cavity during cement mortar filling, thus ensuring the entire structure... "The connection between the reinforced arch bridge structure and the original bridge body is more robust, and the structural integrity is higher." However, this reinforced structure still has the following shortcomings during use: While the corrugated steel plates connected together to form an arch shape do enhance the connection between the pier and the arch, the connection strength provided by the aforementioned split structure alone is not significant enough. Therefore, it is necessary to provide a connecting structure that can significantly enhance the connection strength and improve practicality. In addition, the compressive strength and connection tightness of the reinforced arch structure are not significant enough. Therefore, it is necessary to provide a connecting structure that can significantly enhance the connection tightness and compressive performance, and improve the safety of use. Utility Model Content

[0003] The present invention provides an efficient and reinforced connection structure for the pier and arch of a cross-river arch bridge, which aims to solve the problem that the overall connection strength and compressive strength of the arch need to be improved in existing connection structures.

[0004] To achieve the above objectives, this utility model provides an efficient and reinforced connection structure for the pier body and arch ring of a cross-river arch bridge, including a pier body component and an arch ring component; The pier body assembly includes a first arc-shaped sleeve and a second arc-shaped sleeve. Both ends of the first and second arc-shaped sleeves are fixedly connected to several reinforcing ribs. One end of the first and second arc-shaped sleeves is fixedly connected to a connecting block. The surface of the connecting block has two connecting grooves. The inner walls of the first and second arc-shaped sleeves are fixedly connected to fixing blocks. Several I-beams are movably installed between the two fixing blocks. The lower ends of the first and second arc-shaped sleeves are movably installed with the pier body body. The surface of the pier body body is fixedly connected to two connecting strips. The two connecting strips are snapped into the inside of the connecting grooves. The inside of the pier body body is embedded with a pressure-resistant mechanism. An arch assembly includes several first arch blocks and second arch blocks installed inside a first arc sleeve and a second arc sleeve. The first arch blocks have fixing grooves on both sides, and the second arch blocks have fixing strips fixedly connected to both sides. The fixing strips on both sides of the several second arch blocks are engaged inside the fixing grooves.

[0005] As a preferred embodiment of this utility model, the anti-compression mechanism includes a plurality of mounting rods, a plurality of vertical rods are fixedly connected to each of the plurality of mounting rods, and reinforcing rods are fixedly connected to both ends of each of the plurality of mounting rods.

[0006] As a preferred embodiment of this utility model, the interiors of the first arc-shaped sleeve and the second arc-shaped sleeve are symmetrically and fixedly connected with several locking strips.

[0007] As a preferred embodiment of this utility model, the opposite surfaces of the two fixing blocks at the lower ends of the first arc-shaped sleeve and the second arc-shaped sleeve are provided with a plurality of fastening screw holes, and the two ends of the plurality of I-beams are fixedly connected with fastening bolts, the fastening bolts being threaded into the inside of the fastening screw holes.

[0008] As a preferred embodiment of this utility model, the pier body has an embedded groove inside, the anti-compression mechanism is installed inside the embedded groove, the upper end of the pier body has several connecting holes, several reinforcing ribs are snapped into the connecting holes, the two sides of the first arch block and one end of the fixing strip are all provided with insertion holes, and insertion rods are inserted into the insertion holes.

[0010] As a preferred embodiment of this utility model, the anti-compression mechanism is made of alloy steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When connecting the pier body component and the arch ring through a reinforcement structure, the reinforcing ribs at the ends of the first and second arc-shaped sleeves are embedded and cast into the pier body to form an integrated casting structure. This can initially enhance the connection strength between the arch ring and the pier body. At the same time, the inclined structure at the upper end of the pier body and the inclined surface at the end of the arch ring are completely matched, thus providing a supporting effect and further improving the strength of both. Compared with the reinforcement structure in the existing technology "An Arch Bridge Reinforcement Structure", this utility model can make the arch ring and the pier body form an integrated connection structure through the cooperation of the above structures, thus significantly enhancing the practicality of the connection structure. 2. When the connecting structure is used, the interlocking of the first and second arc-shaped sleeves and the arch assembly can initially provide support for the arch and ensure uniform stress distribution. Simultaneously, the presence of several I-beams at the lower ends of the first and second arc-shaped sleeves further enhances the arch's top support and compressive strength. The pier body, in conjunction with the compressive strength mechanism, ensures the overall compressive strength of the pier body. Finally, several first and second arch blocks, along with connecting rods and fixing strips snapped into the fixing grooves, enhance connection stability, thereby significantly increasing the overall compressive strength of the arch structure. Compared to the existing "arch bridge reinforcement structure," this invention, through the interlocking of the above structures, significantly enhances the overall compressive strength of the arch, thus improving safety in use.

[0015] Example 1

[0016] Please see Figures 1-5 This utility model provides an efficient reinforcement connection structure for the pier body and arch ring of a cross-river arch bridge, including a pier body component 100 and an arch ring component 200. The pier body assembly 100 includes a first arc-shaped sleeve 101 and a second arc-shaped sleeve 102. Both ends of the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 are fixedly connected with several reinforcing ribs 103. One end of the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 is fixedly connected with a connecting block 104. The surface of the connecting block 104 has two connecting grooves 105. The inner walls of the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 are fixedly connected with fixing blocks 106. Several I-beams 107 are movably installed between the two fixing blocks 106. The lower ends of the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 are movably installed with the pier body body 108. The surface of the pier body body 108 is fixedly connected with two connecting strips 109. Both connecting strips 109 are snapped into the inside of the connecting grooves 105. The inside of the pier body body 108 is embedded with a pressure-resistant mechanism 110. The arch assembly 200 includes several first arch blocks 201 and second arch blocks 202 installed inside the first arc sleeve 101 and the second arc sleeve 102.

The fixing strips 204 on both sides of the several second arch blocks 202 are snapped into the inside of the fixing grooves 203.

[0017] In one specific embodiment, the pier body component 100, in conjunction with the arch ring component 200, not only forms an integral structure, significantly enhancing the connection and reinforcement strength, thus improving the practicality of the connection structure, but also, through the mutual cooperation of the above structures, facilitates the enhancement of the overall compressive and tensile strength of the arch ring component 200, thereby improving the safety of the connection structure. In use, the reinforcing ribs 103 at the ends of the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 are embedded and cast into the pier body 108 to form an integral cast structure, thereby initially enhancing the connection strength between the arch ring component 200 and the pier body 108. Simultaneously, the upper inclined surface structure of the pier body 108 and the inclined surface at the end of the arch ring component 200 perfectly fit together, thus providing a supporting effect. To further enhance the connection strength between the two components, the first arc-shaped sleeve 101, the second arc-shaped sleeve 102, and the arch assembly 200 are interlocked, thus initially providing support for the arch assembly 200 and ensuring uniform stress distribution. Then, the several I-beams 107 at the lower ends of the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 further enhance the top support and compressive strength of the arch assembly 200. Simultaneously, the pier body 108, in conjunction with the compressive strength mechanism 110, ensures its overall compressive strength. Next, several insertion rods 212 are inserted into the insertion holes 211, and the fixing strips 204 are engaged within the fixing grooves 203, thereby enhancing connection stability and significantly increasing the overall compressive strength of the arch assembly 200, improving the safety of the connection structure.

[0019] In one specific embodiment, the installation rod 1101, together with the vertical rod 1102 and the reinforcing rod 1103, is cast inside the pier body 108, which can significantly enhance its compressive strength and overall strength, thereby improving its safety in use.

[0020] Please see Figures 2-4 The first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 are both symmetrically fixedly connected with several locking strips 111.

[0021] In one specific embodiment, a plurality of locking strips 111 can improve the connection stability between the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 and the first arch block 201 and the second arch block 202.

[0022] Please see Figures 2-4The two fixing blocks 106 at the lower ends of the first arc sleeve 101 and the second arc sleeve 102 are provided with several fastening screw holes 121 on their opposite surfaces. Both ends of several I-beams 107 are fixedly connected with fastening bolts 122, and the fastening bolts 122 are threaded into the inside of the fastening screw holes 121.

[0023] In one specific embodiment, the fastening bolt 122 is threaded into the fastening bolt hole 121, which can enhance the connection strength between the I-beam 107 and the first arc sleeve 101 and the second arc sleeve 102 and facilitate the disassembly and assembly of each component.

[0024] Please see Figures 2-4 The pier body 108 has an embedded groove 131 inside, and the anti-compression mechanism 110 is installed inside the embedded groove 131. The upper end of the pier body 108 has several connecting holes 132, and several reinforcing ribs 103 are snapped into the connecting holes 132. The two sides of the first arch block 201 and one end of the fixing strip 204 are all provided with insertion holes 211, and insertion rods 212 are inserted into the insertion holes 211.

[0025] In one specific embodiment, the embedded groove 131 and the connecting hole 132 can improve the installation stability of the anti-compression mechanism 110 and the reinforcing rib 103. The plug rod 212 is inserted into the plug hole 211, which can enhance the connection stability between the first arch block 201 and the second arch block 202, and thus help to enhance the connection tightness between the first arch block 201 and the second arch block 202.

[0026] Please see Figure 5 The inner walls and side surfaces of the first arch block 201 and the second arch block 202 are provided with strip grooves 221, and the locking strip 111 is engaged inside the strip groove 221.

[0027] In one specific embodiment, the clip 111 is engaged inside the strip groove 221 to enhance the connection strength between the first arc sleeve 101 and the second arc sleeve 102 and the first arch block 201 and the second arch block 202.

[0028] Please see Figures 2-4 The compression-resistant mechanism 110 is made of alloy steel.

[0029] In one specific embodiment, the anti-compression mechanism 110 made of alloy steel can significantly enhance its compressive and tensile strength, ensuring the overall compressive strength of the pier body 108.

[0030] Working principle: In use, the reinforcing ribs 103 at the ends of the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 are embedded and cast into the pier body 108 to form an integrated cast structure, which initially enhances the connection strength between the arch ring component 200 and the pier body 108. At the same time, the upper inclined surface structure of the pier body 108 and the inclined surface at the end of the arch ring component 200 completely fit together, which can play a supporting role, thus further improving the connection strength between the two. Finally, the first arc-shaped sleeve 101 and the second arc-shaped sleeve 102 are interlocked with the arch ring component 200, thereby initially achieving the function of the arch ring component. The arch ring assembly 200 provides support and ensures uniform stress distribution. In conjunction with the first arc sleeve 101 and the second arc sleeve 102, several I-beams 107 at the lower end further enhance the top support and compressive strength of the arch ring assembly 200. The pier body 108, in conjunction with the compressive strength mechanism 110, ensures its overall compressive strength. At the same time, several plug-in rods 212 are inserted into the plug-in holes 211, and the fixing strips 204 are snapped into the fixing grooves 203 to enhance the connection stability. This significantly enhances the overall compressive strength of the arch ring assembly 200 and improves the safety of the connection structure.
