Description

Technical Field

[0001] The utility model relates to bridge construction, more specifically, it relates to a bridge. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, seas, or above the ground to enable vehicles and pedestrians to pass smoothly. To adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient.

[0003] At present, common bridges include several piers and bridges set on top of the piers. Guardrails are set on both sides of the bridge. The guardrails can effectively prevent vehicles or pedestrians from accidentally falling off the edge of the bridge, thereby ensuring the safety of pedestrians and vehicles. At the same time, it can also guide vehicles to the correct driving road and reduce traffic accidents caused by lane deviation.

[0004] However, in the current process of installing bridge guardrails, an installation pit is usually dug on the surface of the bridge, and some connecting parts are embedded in the installation pit. The embedded parts will provide a basis for the installation of the guardrail. When installing the guardrail, the bottom column of the guardrail can be welded or bolted to the embedded parts to fix the guardrail. Finally, the original installation pit is filled with concrete to combine it with the bottom column of the guardrail, thereby completing the process of installing the guardrail. When the guardrail is damaged by impact, it needs to be replaced in time. When replacing the guardrail of this type of bridge, the poured and fixed concrete needs to be removed first, and the concrete needs to be poured again after the replacement is completed, which is time-consuming and labor-intensive, resulting in a high construction cost for replacing the guardrail. Utility Model Content

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] See also Figure 1-2 As shown, the bridge comprises a pier 1 and a bridge 2 arranged on the top of the pier 1. Guardrails 3 are arranged on both sides of the bridge 2. The guardrails 3 are made of stainless steel. The stainless steel material has high strength and corrosion resistance, so that the guardrails 3 have a long service life. A plurality of mounting seats 4 are arranged on the top of the bridge 2. Mounting grooves 5 are opened in the mounting seats 4. Mounting blocks 6 for being inserted into the mounting grooves 5 are arranged at the bottom of the columns of the guardrail 3. A limiting component for limiting the movement of the mounting block 6 is arranged on the mounting seat 4. In the process of installing the guardrail 3, the mounting block 6 can be aligned with the mounting groove 5 and inserted. When the mounting block 6 is completely inserted into the mounting groove 5, After being inserted, the mounting block 6 can be limited by the limiting component to prevent the mounting block 6 from moving out of the mounting groove 5, thereby ensuring the stability and safety of the guardrail 3. When the guardrail 3 is damaged and needs to be replaced, the mounting block 6 can be removed from the mounting groove 5 by releasing the limiting component on the mounting block 6, thereby facilitating the removal of the damaged guardrail 3 for replacement. The disassembly and assembly of the guardrail 3 is achieved by limiting and disengaging the mounting block 6 in the mounting groove 5, and the operation is relatively convenient. At the same time, during the process of replacing the guardrail 3, there is no need to fill additional concrete for fixing, and the limiting component can be reused, thereby facilitating reducing construction costs.

[0021] See also Figure 2-3 As shown, the limiting assembly includes two limiting blocks 7 of equal shape and size, and the limiting blocks 7 are L-shaped in cross section. The inner side walls of the two limiting blocks 7 are respectively used to conflict with the four side walls of the guardrail 3 column. The limiting blocks 7 are detachably mounted on the top of the mounting seat 4 through a plurality of fixing members 12. When the two limiting blocks 7 are mounted on the top of the mounting seat 4, their inner side walls will conflict with the four side walls of the guardrail 3 column respectively, which can prevent the mounting block 6 from moving or rotating in any direction in the mounting groove 5, thereby ensuring the protection. The stability and position accuracy of the fence 3 column in the installation groove 5. At the same time, the limit block 7 can be removed by releasing the fixation of the fixing piece 12 on the limit block 7, thereby releasing the limit on the installation block 6, which is convenient for the removal of the guardrail 3. A panel 11 for contacting the guardrail 3 column is integrally formed on the top of the limit block 7, and the panel 11 and the limit block 7 are perpendicular to each other. By setting the panel 11, the contact area between the limit block 7 and the guardrail 3 column can be increased, thereby further increasing the stability of the column.

[0022] See also Figure 2As shown, a support platform 8 is provided at the top edge of the mounting seat 4, and the support platform 8 is integrally formed with the mounting seat 4. In this way, the integrity and firmness between the mounting seat 4 and the support platform 8 are greatly enhanced, which not only simplifies the manufacturing process, but also greatly improves the service life of the two. The top of the support platform 8 is used to abut against the limit block 7, and the fixing member 12 is a bolt and a nut that match each other. Through holes for the bolts to pass through are provided on the limit block 7 and the support platform 8. By providing the support platform 8, the top of the support platform 8 directly abuts against the limit block 7, so that the limit The positioning block 7 can be stably installed on the mounting base 4 without shaking or shifting. At the same time, the positioning block 7 is fixed by bolts and nuts. The threaded connection between the bolts and the nuts has reliable connection strength, so that the positioning block 7 has a good fixing effect. At the same time, the fixation of the positioning block 7 can be released by removing the nut from the bolt. The operation is relatively convenient. The nut is a butterfly nut. The head design of the butterfly nut allows it to be rotated by simple hand tools or bare hands, so as to quickly tighten or loosen the bolt, and the operation is relatively labor-saving.

[0023] See also Figure 2 As shown, straight grooves 9 are transversely opened on both sides of the mounting block 6, and convex ridges 10 are transversely arranged on the inner walls on both sides of the mounting seat 4, and the convex ridges 10 are used to slide in the straight grooves 9. In the process of the mounting block 6 being inserted into the mounting groove 5, the convex ridges 10 are in conflict with the inner edges of the straight grooves 9, and slide in the straight grooves 9 as the mounting block 6 is inserted into the mounting groove 5, thereby guiding the insertion of the mounting block 6, so that the operation of inserting the mounting block 6 into the mounting groove 5 is relatively smooth.
