[0029] See also Figure 1-4 , the utility model provides a technical solution:
[0030] An L-shaped bridge pier using prestressed concrete includes a base 4, a connecting groove 7 is formed at the upper end of the base 4, a lower groove wall of the connecting groove 7 is formed with docking holes 8 around, a plurality of docking holes 8 are formed, a docking block 5 is fixedly connected to the middle of the lower groove wall of the connecting groove 7, a casting cement body 1 is fixedly connected to the upper end of the docking block 5, a plurality of No. 1 insertion holes 6 are formed at the lower outer side of the casting cement body 1, a warning device 2 is sleeved on the outer side of the casting cement body 1, and a reinforcement device 3 is fixedly connected to the outer side of the warning device 2.
[0031] In this embodiment, the warning device 2 includes an outer elastic plate 21, and a plurality of docking columns 24 are fixedly connected to the lower end of the outer elastic plate 21, and a reflective warning sticker 22 is fixedly connected to the outer side of the outer elastic plate 21. A plurality of No. 2 insertion holes 23 are opened at the lower outer side of the outer elastic plate 21. The outer elastic plate 21 is sleeved on the outer side of the cast cement body 1; the outer elastic plate 21 is a hollow L-shaped structure, and the plurality of docking columns 24 are equidistantly distributed in an L-shape; the position dimensions of the plurality of No. 2 insertion holes 23 are matched one by one with the position dimensions of the plurality of reinforcing steel bars 32, and the position dimensions of the plurality of docking columns 24 correspond one by one with the position dimensions of the plurality of docking holes 8;.
[0032] Through the above scheme: the hollow L-shaped structure of the outer elastic plate 21 is designed to match the shape of the L-shaped bridge pier, so that it can be tightly sleeved on the outside of the cast cement body 1 to play a role of wrapping and protection. On the one hand, its elastic material can buffer the impact of external collisions to a certain extent and reduce the impact on the internal structure; on the other hand, it is also convenient for installation and disassembly. The docking columns 24 are evenly distributed in an L shape. When the outer elastic plate 21 is sleeved on the cast cement body 1, the docking columns 24 can be inserted into the docking holes 8 on the base 4 to achieve a firm connection and precise positioning between the warning device 2 and the base 4, ensuring that the warning device 2 will not be easily displaced or shaken, and enhancing the stability of the overall structure. The reflective warning sticker 22 uses its reflective properties to reflect light in poorly lit environments such as at night or in foggy days, so that passing vehicles or pedestrians can more easily notice the bridge pier, playing an important role in safety warnings and reducing the risk of accidents such as collisions.
[0033] In this embodiment, the reinforcement device 3 includes a reinforcement plate 31, and a plurality of reinforcement steel bars 32 are inserted and connected to the outer side of the reinforcement plate 31, and the outer surfaces of the plurality of reinforcement steel bars 32 are threadedly connected to the fastening sleeves 33, and the reinforcement plate 31 is fixedly connected to the outer side of the outer elastic plate 21; the reinforcement plate 31 has a special-shaped structure, and the reinforcement plate 31 is tightly attached to the upper end of the base 4; and a plurality of reinforcement steel bars 32 are cross-distributed in the reinforcement plate 31.
[0034] Through the above scheme: the special-shaped structure design of the reinforcement plate 31 is to better fit with the upper end of the base 4 and the external elastic plate 21. This close fit can enhance the integrity of the structure on the one hand, and effectively transmit and disperse the forces from different directions on the other hand. The reinforcement plate 31 is tightly attached to the upper end of the base 4, which can share part of the external force and improve the horizontal stability of the entire pier structure. The reinforcement steel bars 32 are cross-distributed in the reinforcement plate 31. Such a layout enables the reinforcement device 3 to have a strong reinforcement effect in multiple directions. When subjected to external force, the reinforcement plate 31 and the reinforcement steel bars 32 work together to resist the external force through their own strength and rigidity to prevent the pier from large displacement or deformation. The fastening sleeve 33 is threadedly connected to the reinforcement steel bars 32 to fasten and fix the reinforcement steel bars 32. It ensures that the position of the reinforcement steel bars 32 in the reinforcement plate 31 is stable and will not easily loosen or fall out, thereby ensuring that the reinforcement device 3 continues to play an effective role and further improves the reliability and durability of the entire structure.
[0035] It should be noted that the utility model is an L-shaped bridge pier using prestressed concrete. During use, when installing, first place the cast cement body 1 in the connecting groove 7 of the base 4 through the docking block 5 at the bottom to achieve preliminary positioning. Then, the outer elastic plate 21 of the warning device 2 is sleeved on the outside of the cast cement body 1, so that the docking column 24 at the lower end of the outer elastic plate 21 corresponds to and is inserted into the docking hole 8 of the lower groove wall of the connecting groove 7, ensuring that the warning device 2 is installed firmly and accurately in the position. At this time, the reinforcement plate 31 of the reinforcement device 3 is also tightly attached to the upper end of the base 4, which plays a role in enhancing stability. In daily use, the reflective warning sticker 22 uses its reflective properties to remind passing vehicles and pedestrians and reduce the risk of collision. The outer elastic plate 21 utilizes its elasticity to buffer minor external collisions and vibrations and protect the bridge piers. On the other hand, it also helps to maintain a close fit with the poured cement body 1. The reinforcing plate 31 and the cross-distributed reinforcing steel bars 32 in the reinforcing device 3 jointly improve the overall strength and rigidity of the bridge piers. When the bridge piers are subjected to external forces, such as wind force, vehicle collision, etc., the reinforcing device 3 can effectively disperse and resist these external forces to prevent the bridge piers from being greatly deformed or damaged. The fastening sleeve 33 ensures the stable connection of the reinforcing steel bars 32 in the reinforcing plate 31. At the same time, the No. 1 through hole 6 and the No. 2 through hole 23 can be used to insert other auxiliary fixing or connecting components to enhance the reliability of the overall structure. The entire device works in coordination, so that the L-shaped bridge pier has a good warning function while ensuring the stability of the structure to adapt to various use environments and situations, and can ensure the safety and conspicuousness of the bridge piers and ensure the smooth operation of traffic.
