The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figures 1 to 3As shown, a steel structure bridge guardrail includes a bridge body 1. Two pedestrian walkways 2 are fixedly connected to the top of the bridge body 1. Several first guardrail frames 3 are fixedly connected to one side of each pedestrian walkway 2. A protective net 4 is attached to one side of each guardrail frame 3, supporting the net 4. The bridge protective net is 4 meters high to prevent pedestrians from climbing while enjoying the view or playing on the bridge. Several fixed frames 5 are attached to one side of each first guardrail frame 3, and two threaded holes are opened on one side of each fixed frame 5. Several second guardrail frames 6 are fixedly connected to one side of each pedestrian walkway 2. Used to separate pedestrians and vehicles, preventing vehicles from hitting pedestrians and also preventing pedestrians from walking onto the vehicle passage. Each second guardrail 6 has a first groove 9 on one side, and a first hollow tube 10 is inserted inside each first groove 9. Each second guardrail 6 has two second grooves 11 on one side, and a second hollow tube 12 is inserted inside each second groove 11. A connecting rod 13 is fixedly connected to one side of every two corresponding first guardrails 3. The connecting rod 13 strengthens the protection for pedestrians and provides support for the protective net 4 to prevent the protective net 4 from being blown over by strong winds.

[0028] Several fixing plates 7 are attached to one side of the protective net 4, and each fixing plate 7 has two fixing screws 8 threaded inside.

[0029] The external thread of each fixing screw 8 is connected to the interior of the corresponding threaded hole.

[0030] Each fixing screw 8 is inserted into the inside of the guardrail 4. The fixing screw 8 connects the fixing plate 7 and the fixing frame 5, thereby making the guardrail 4 snapped between the fixing plate 7 and the first guardrail frame 3.

[0031] Each first hollow tube 10 has a third groove inside and a first protrusion on its outer surface. The inner surface of each third groove is threaded to the outer surface of the corresponding first protrusion. Two corresponding first hollow tubes 10 are connected through the third groove and the first protrusion to form a bridge safety net to protect pedestrians.

[0032] Each second hollow tube 12 has a fourth groove inside and a second protrusion on its outer surface. The inner surface of each fourth groove is threaded to the outer surface of the corresponding second protrusion.

[0033] Each sidewalk 2 has several light-sensitive lamps 14 (known technology) fixedly connected to its top. The light-sensitive lamps 14 automatically emit light and illuminate the sidewalk after sensing that the sunlight is weakening.

[0034] A steel structure bridge guardrail works on the following principle:

[0035] 1) Place the first guardrail frame 3 and the second guardrail frame 6 above the sidewalk, and then pour concrete on the base of the first guardrail frame 3, the second guardrail frame 6 and the light-sensitive lamp 14 to connect the first guardrail frame 3, the second guardrail frame 6 and the light-sensitive lamp 14 to the bridge.

[0036] 2) Place the protective net 4 on one side of the first guardrail frame 3, fit the fixing frame 5 onto the outer surface of the first guardrail frame 3, and then place the fixing piece 7 on one side of the protective net 4. Connect the fixing piece 7 and the fixing frame 5 with the fixing screw 8, so that the protective net 4 is snapped between the fixing piece 7 and the first guardrail frame 3, thereby the first guardrail frame 3 provides support for the protective net 4 and prevents the protective net 4 from being blown over by strong winds;

[0037] 3) Place the first hollow tube 10 into the corresponding first groove 9, and then connect the two corresponding first hollow tubes 10 through the third groove and the first protrusion. Place the second hollow tube 12 into the corresponding second groove 11, and connect the two corresponding second hollow tubes 12 through the fourth groove and the second protrusion to form a bridge protection net for pedestrians.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] 1. This device is equipped with a protective net 4. The protective net 4 is placed on one side of the first guardrail frame 3. The fixing frame 5 is fitted onto the outer surface of the first guardrail frame 3. Then, the fixing plate 7 is placed on one side of the protective net 4. The fixing plate 7 and the fixing frame 5 are connected by fixing screws 8, so that the protective net 4 is snapped between the fixing plate 7 and the first guardrail frame 3. Thus, the first guardrail frame 3 provides support for the protective net 4, which helps to prevent the protective net 4 from being blown over by strong winds. The height of the bridge protective net is 4 meters, which helps to prevent pedestrians from climbing when they are enjoying the scenery and playing on the bridge, effectively protecting the safety of pedestrians.

[0040] 2. This device is equipped with a second guardrail frame. The first hollow tube 10 is placed inside the corresponding first groove 9, and then the two corresponding first hollow tubes 10 are connected through the third groove and the first protrusion. The second hollow tube 12 is placed inside the corresponding second groove 11, and the two corresponding second hollow tubes 12 are connected through the fourth groove and the second protrusion. This facilitates the formation of a bridge safety net to protect pedestrians, which helps to separate pedestrians and vehicles, prevents vehicles from hitting pedestrians, and also prevents pedestrians from walking down to the vehicle passageway.
