[0002] Bridge construction faces challenges such as complex construction environments, especially when building bridges across rivers, where navigation significantly increases the difficulty. Existing bridge construction systems often suffer from poor support performance, leading to side slippage of crossbeams under heavy loads or lateral forces. Furthermore, pedestrians and vehicles may not immediately detect these malfunctions, increasing the risk of serious accidents. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tie rod support for a steel pipe concrete tied arch bridge.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A tie rod support for a steel-concrete composite tied arch bridge includes a pier assembly, a main longitudinal beam, a distribution beam, and tie rods. The pier assembly has a supporting cap beam at its top, and the main longitudinal beam is installed on top of the supporting cap beam. Reinforcing ribs are provided between the supporting cap beam and the pier assembly. The distribution beam is fixed to the top of the main longitudinal beam, and tie rods are provided at the top of the distribution beam. A safety alarm mechanism cooperating with the distribution beam is provided at the top of the pier assembly. The safety alarm mechanism includes a fixed base, which is L-shaped. Several grooves are evenly distributed on the outer surface of the L-shape of the fixed base. Guide rods are provided on both sides of the grooves, and a sliding seat is slidably connected between two guide rods. A spring cooperating with the sliding seat is sleeved on the guide rod. A protrusion and an elastic compression block are respectively provided in the middle of both sides of the sliding seat. The protrusion extends through the opening of the groove to the outside of the fixed base. A compression switch cooperating with the elastic compression block is fixed at the center of the bottom of the groove. A buffer assembly cooperating with the distribution beam is also provided on the fixed base.

[0006] Furthermore, the buffer assembly includes a storage groove formed on the L-shaped outer surface of the fixed base, a sliding block is slidably connected inside the storage groove, a buffer block is fixed in the middle of one side of the sliding block, the end of the buffer block extends through to the outside of the fixed base, and a spring is provided between the outer surface of the other side of the buffer block and the inner wall of the storage groove.

[0007] Furthermore, the sliding block and the buffer block are an integral structure, and the side of the buffer block away from the sliding block has an inclined structure.

[0008] Furthermore, two adjacent distribution beams are connected and fixed by an intermediate beam, and an elastic sealing gasket that fits against the protrusion is provided on the inner wall of the opening of the groove.

[0009] Furthermore, the outer surface of the fixing base is provided with a sound alarm, the outer side of the sound alarm is covered with a protective cover, the outer surface of the protective cover is provided with a light alarm, the fixing base is provided with an inner cavity, and the inner cavity is provided with a controller, a storage battery and a memory. The squeeze switch, the storage battery and the memory are all electrically connected to the controller.

[0010] Furthermore, the support group includes a front support, a rear support, and several intermediate supports arranged at intervals, with the intermediate supports located between the front support and the rear support.

[0011] Furthermore, the main longitudinal beam is composed of multiple Bailey bridge sections, and the supporting cap beam is an I-beam.

[0012] Furthermore, the front end support includes two front end steel pipes, the rear end support includes two rear end steel pipes, and the middle support includes four middle steel pipes.

[0013] The beneficial effects of this utility model are:

[0014] Through the design of the safety alarm mechanism, when the distribution beam slips under heavy pressure or lateral force, the distribution beam will shift, squeezing the protrusion. The protrusion will move into the groove in the fixed seat. During the movement, the protrusion will drive the elastic squeezing block to move through the sliding seat. The movement of the elastic squeezing block will squeeze and touch the squeezing switch. The squeezing switch will send a signal to the controller, which will activate the sound alarm and light alarm to alert passersby that an accident has occurred. This allows for immediate safety alarms when danger occurs, enabling timely safety handling.

[0015] Through the design of the buffer component, when the distribution beam is subjected to heavy pressure or lateral movement, the distribution beam will squeeze several buffer blocks. The buffer blocks will move into the storage groove and push the sliding block to squeeze the spring. The spring will buffer the impact force when the distribution beam contacts the fixed seat, so that the hard contact becomes a flexible release, reducing the damage caused by the impact.

[0016] By reinforcing the ribs and fixing the base, the stability of the fixing base is improved. The fixing base can provide temporary support when the distribution beam is subjected to heavy pressure or lateral movement, thus giving maintenance personnel time to repair and facilitate maintenance.

[0024] Please see Figures 1-4This utility model provides a technical solution for a tie-rod support for a steel-concrete composite tied arch bridge, including a pier group, a main longitudinal beam 5, a distribution beam 6, and tie rods 7. The pier group includes a front pier 1, a rear pier 2, and several intermediate piers 3 spaced apart. The intermediate piers 3 are located between the front piers 1 and the rear piers 2. The main longitudinal beam 5 is composed of multiple Bailey bridge sections. The supporting cap beam 4 is an I-beam. The front pier 1 includes two front end steel pipes, the rear pier 2 includes two rear end steel pipes, and the intermediate piers 3 include four intermediate steel pipes. The top of the pier group is equipped with... A supporting cap beam 4 is provided, and the main longitudinal beam 5 is installed on top of the supporting cap beam 4. A reinforcing rib 24 is provided between the supporting cap beam 4 and the support pier assembly. A distribution crossbeam 6 is fixed on top of the main longitudinal beam 5, and a tie rod 7 is provided on top of the distribution crossbeam 6. A safety alarm mechanism that cooperates with the distribution crossbeam 6 is provided on top of the support pier assembly. The safety alarm mechanism includes a fixed base 9, which is an L-shaped structure. Several grooves 13 are evenly opened on the outer surface of the L-shaped fixed base 9. Guide rods 14 are provided on both sides inside the grooves 13, and two guide rods 14 slide between each other. A sliding seat 15 is connected to the guide rod 14, and a spring 16 is sleeved on the guide rod 14 to cooperate with the sliding seat 15. A protrusion 17 and an elastic compression block 18 are respectively provided on the middle of both sides of the sliding seat 15. The protrusion 17 passes through the opening of the groove 13 to the outside of the fixed seat 9. A compression switch 19 cooperating with the elastic compression block 18 is fixed at the center of the inner bottom of the groove 13. The fixed seat 9 is also provided with a buffer assembly that cooperates with the distribution beam 6. Through the design of the safety alarm mechanism, when the distribution beam 6 slips under heavy pressure or lateral force, a buffer is activated. When the distribution beam 6 is displaced, it will press against the protrusion 17. The protrusion 17 will move into the groove 13 in the fixed seat 9. During the movement, the protrusion 17 will drive the elastic pressing block 18 to move through the sliding seat 15. The movement of the elastic pressing block 18 will press against the pressing switch 19. The pressing switch 19 will send a signal to the controller, which will activate the sound alarm 10 and the light alarm 12 to provide sound and light alarms, thereby alerting passers-by that an accident has occurred. This will allow for immediate safety alarms when danger occurs, enabling timely safety handling.

[0025] See Figures 1-4The buffer assembly includes a receiving groove 20 formed on the L-shaped outer surface of the fixed base 9. A sliding block 21 is slidably connected inside the receiving groove 20. A buffer block 22 is fixed to the middle of one side of the sliding block 21. The end of the buffer block 22 extends to the outside of the fixed base 9. A spring 23 is provided between the outer surface of the other side of the buffer block 22 and the inner wall of the receiving groove 20. The sliding block 21 and the buffer block 22 are an integral structure. The side of the buffer block 22 away from the sliding block 21 is a sloping structure. Two adjacent distribution beams 6 are connected and fixed by a middle beam 8. An elastic sealing gasket that fits against the protrusion 17 is provided on the inner wall of the opening of the groove 13. The outer surface of the fixed base 9... A sound alarm 10 is provided, and a protective cover 11 is fitted over the outside of the sound alarm 10. A light alarm 12 is provided on the outer surface of the protective cover 11. The fixed base 9 has an inner cavity, and a controller, a battery, and a memory are located inside the inner cavity. The squeeze switch 19, the battery, and the memory are all electrically connected to the controller. Through the design of the buffer assembly, when the distribution beam 6 is subjected to heavy pressure or lateral movement, the distribution beam 6 will squeeze several buffer blocks 22. The buffer blocks 22 will move into the storage groove 20 and push the sliding block 21 to squeeze the spring 16. The spring 16 will buffer the impact force when the distribution beam 6 contacts the fixed base 9, so that the hard contact becomes a flexible contact, reducing the damage caused by the impact.

[0026] When the distribution beam 6 slips under heavy pressure or lateral force during use, the distribution beam 6 will shift and press against the protrusion 17. The protrusion 17 will move into the groove 13 in the fixed seat 9. During the movement, the protrusion 17 will drive the elastic pressing block 18 to move through the sliding seat 15. The movement of the elastic pressing block 18 will press against the pressing switch 19. The pressing switch 19 will send a signal to the controller, which will activate the sound alarm 10 and the light alarm 12 to provide sound and light alarms, thereby alerting passersby that an accident has occurred. This will allow for immediate safety alarms when danger occurs, enabling timely safety handling.

[0027] By reinforcing the ribs 24 and fixing the base 9, the stability of the fixing base 9 is improved. The fixing base 9 can provide temporary support when the distribution beam 6 is subjected to heavy pressure or lateral movement, thus giving maintenance personnel time to repair and facilitating maintenance.

[0028] When the distribution beam 6 is subjected to heavy pressure or lateral movement, the distribution beam 6 will squeeze several buffer blocks 22. The buffer blocks 22 will move into the storage groove 20 and push the sliding block 21 to squeeze the spring 16. The spring 16 will buffer the impact force when the distribution beam 6 contacts the fixed seat 9, so that the hard contact becomes a flexible release, reducing the damage caused by the impact.

[0029] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
