[0002] A multi-span stone flat beam bridge is composed of components such as a stone flat beam bridge slab, a coping stone, a vertical wall column, and a water pan stone. Some bridges of this type, due to their long construction age, changes in usage functions, and lack of maintenance management in later periods, often have serious diseases such as missing or broken original stone bridge slabs.

[0003] In the prior art, due to the lack of existing repair technologies, when repairing a broken stone flat beam bridge with cultural relic value, maintenance workers usually repair the original structural parts that can be retained. When there are some original structural parts that cannot be retained, reinforcement is usually carried out. However, in the existing reinforcement process, the reinforcement process is cumbersome, resulting in increased difficulty in disassembly and reduced efficiency during disassembly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following further elaborates on the present application in conjunction with Figure 1 -3.

[0031] The embodiment of the present application discloses a steel structure reinforcement structure for a stone beam bridge.

[0032] The observation views (front, back, left, right) of this device are based on Figure 1 the attached drawings as a reference benchmark.

[0033] Embodiment 1

[0034] Reference Figure 1 and 2 , a steel structure reinforcement structure for a stone beam bridge, including the broken bridge one 1 and the broken bridge two 101 after the stone beam bridge breaks. The two ends of the capping beam stone 102 are respectively fixedly connected to the lower surface of the broken bridge one 1 or the broken bridge two 101 and the upper surface of the vertical wall column 103. The two ends of the vertical wall column 103 are respectively fixedly connected to the upper surface of the capping beam stone 102 and the upper surface of the ground. The upper end of the bridge 104 is fixedly connected to the middle of the lower ends of the broken bridge one 1 and the broken bridge two 101. The stabilizing mechanism 2 includes L-shaped angle steels 201 symmetrically and fixedly connected to both sides of the broken bridge one 1 and the broken bridge two 101. The upper end of the bonding steel plate 202 is fixedly connected to the lower end of the bridge 104 through an adhesive. The inside of the U-shaped steel hoop plate 203 is fixed to the outside of the bonding steel plate 202 and the bridge 104 through chemical anchor bolts. One side of the steel pressing strip 204 fixedly connects all the U-shaped steel hoop plates 203 together through chemical anchor bolts. The inner wall of the semi-circular ring 205 is sleeved on the outside of the vertical wall column 103. The extension blocks 206 are symmetrically and fixedly connected to both sides of the semi-circular ring 205. The outside of the bolt 207 is threadedly connected to the inside of the extension block 206 to fix the two semi-circular rings 205 to the outer wall of the vertical wall column 103. The two ends of the support block 208 are respectively fixedly connected to the middle of the outer wall on the other side of the semi-circular ring 205 and the bottom of the abutting plate 209. The two ends of the abutting plate 209 are respectively fixedly connected to the lower surface of the broken bridge one 1 and the broken bridge two 101 and the middle of the upper surface of the support block 208. One side of the auxiliary piece 210 is symmetrically and fixedly connected to the upper end of the semi-circular ring 205. The other side of the long strip steel 211 is symmetrically and fixedly connected to both sides of the support block 208.

[0035] By setting, when serious diseases such as the absence or fracture of the original stone bridge deck occur, in order to protect the value of the cultural relic components of the stone bridge and provide the greatest possibility for the repair of the "cultural relic components" for possible future technological updates, the repairer first fixes the L-shaped angle steel 201 on both sides of the broken bridge one 1 and the broken bridge two 101 by welding, then uses an adhesive to bond the bonding steel plate 202 to the fracture of the bridge 104, then sleeves the U-shaped steel hoop plate 203 on the outside of the bonding steel plate 202 and the U-shaped steel hoop plate 203, and then fixes the bottom of the bridge 104, the bonding steel plate 202 and the U-shaped steel hoop plate 203 through chemical anchor bolts, and then uses chemical anchor bolts and the steel pressing strip 204 to connect and fix all the U-shaped steel hoop plates 203 on both sides of the bridge 104 to complete the basic fixation of the fracture.

[0036] Subsequently, the semi-circular piece 205 is fixed to the outside of the coping stone 102 and the vertical wall column 103 through bolts 207. Subsequently, by welding the support block 208 and the abutting plate 209, the semi-circular piece 205 can increase the support on both sides of the bridge deck fracture. Subsequently, by welding the auxiliary piece 210 to the upper end of the semi-circular piece 205 and the middle part of the support block 208, the stress condition of the support block 208 is reduced to prevent the support block 208 from breaking. Subsequently, the vertical wall columns 103 on both sides of the fracture are connected by the long strip steel 211 between the support block 208 and the auxiliary piece 210 to prevent the inclination of the vertical wall columns 103 from causing the bridge deck collapse due to the fracture.

[0037] Refer to Figure 1 、 3 , the detachable mechanism 3 includes a circular through hole one 301 penetratingly opened on one side of the long strip steel 211. The outer side of the sliding column one 302 is slidably connected to one side inside the circular through hole one 301. The outer side of the sliding column two 303 is slidably connected to the other side inside the circular through hole one 301. One end of the threaded column 304 is rotatably connected to the inside of the sliding column one 302. The other end of the threaded column 304 is threadedly connected to the inside of the threaded groove 306. Both ends of the spring 305 are respectively fixedly connected to the surface between the sliding column one 302 and the sliding column two 303. The threaded groove 306 is opened on one side surface of the sliding column two 303. The arc grooves 307 are respectively opened on one side of the middle part of the surface between the sliding column one 302 and the sliding column two 303. The middle part of the moving column 308 movably penetrates and is clamped inside another long strip steel 211. One side of the convex block 309 is fixedly connected to one side of the moving column 308. One side of the fixing piece 310 is fixedly connected to the other side of the convex block 309. Both sides of the fixing piece 310 are clamped inside the arc grooves 307. The circular through hole two 311 penetrates and is opened on one side outer wall of the long strip steel 211.

[0038] By setting, when connecting the two long strip steels 211 or when the "cultural relic components" can be repaired during later technical updates, by rotating the threaded column 304, the sliding column one 302 and the sliding column two 303 slide inside the circular through hole one 301. By the sliding of the sliding column two 303 inside the circular through hole one 301, the spring 305 starts to expand and contract. At this time, by a large mechanical device, the moving column 308 is slid. By the sliding of the moving column 308, the fixing piece 310 can slide inside the circular through hole two 311 and the circular through hole one 301. When the fixing piece 310 slides inside the circular through hole one 301, the fixing or non-fixing of the fixing piece 310 can be completed through the sliding column two 303 and the threaded column 304. By fixing the fixing piece 310, the two long strip steels 211 can be connected. By not fixing the fixing piece 310, the disassembly of the long strip steel 211 can be completed.

[0039] The implementation principle of a steel structure reinforcement structure for a stone beam bridge in an embodiment of this application is as follows: The maintenance staff fixes the L-shaped angle steel 201 on both sides of the broken bridge one 1 and the broken bridge two 101. Subsequently, the bottom of the bonding steel plate 202 and the U-shaped steel hoop plate 203 is fixed to the bottom of the bridge 104 by chemical anchor bolts. Then, all the U-shaped steel hoop plates 203 are connected and fixed to both sides of the bridge 104 through chemical anchor bolts and steel straps 204 to complete the basic fixation of the fracture. Subsequently, the semi-circular sheet 205 is fixed to the outside of the coping stone 102 and the vertical wall column 103 by bolts 207. Then, the broken bridge one 1 and the broken bridge two 101 are locally supported by the support block 208 and the abutting plate 209. The force on the support block 208 is reduced by the auxiliary sheet 210. By rotating the threaded column 304, the sliding column one 302 and the sliding column two 303 slide inside the circular through hole one 301. Then, by the sliding of the moving column 308, the fixing piece 310 slides inside the circular through hole one 301, and the two long steel bars 211 can be connected or disassembled. At the same time, the connection reinforcement or disassembly and repair of the broken bridge one 1 and the broken bridge two 101 can also be indirectly completed.

[0040] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application based on this, therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
