Description

Technical Field

[0001] The utility model relates to the field of guardrails, and more specifically, to a bridge guardrail. Background Art

[0002] A bridge guardrail refers to a guardrail built on the edge of a bridge, which serves to prevent people and vehicles from falling off the bridge. Generally, a bridge guardrail consists of a support structure fixedly connected to the ground and a blocking structure fixedly connected between the support structures. The blocking structure is generally composed of multiple horizontally arranged railings. When installing the existing railings, they need to be fixed to the support structure one by one, and it is rather cumbersome to complete the installation of multiple railings.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a bridge guardrail.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A bridge guardrail includes several railings and several parallel vertical plates. The vertical plates are grouped in pairs of two, and several fixed pipe clamps are fixedly connected between the vertical plates in the same group. A connecting rod is rotatably connected between the vertical plates in the same group, and several movable pipe clamps are fixedly connected to the connecting rod. A pair of corresponding movable pipe clamps and fixed pipe clamps clamp a railing.

[0006] The utility model is further provided that: Elastic pads are fixedly connected to the inner side walls of the movable pipe clamps and the inner side walls of the fixed pipe clamps.

[0007] The utility model is further provided that: The connecting rod and the movable pipe clamps are both located on the side of the fixed pipe clamp away from the bridge deck.

[0008] The utility model is further provided that: Fixed blocks are fixedly connected to the side walls of the vertical plates in the same group, and the end of the connecting rod is detachably connected to the fixed block.

[0009] The utility model is further provided that: A bolt is slidably connected to the fixed block, and the bolt simultaneously penetrates through the fixed block, the vertical plate, and the connecting rod.

[0010] The utility model is further provided that: A limiting rod is fixedly connected between the vertical plates in the same group, and the limiting rod is located on the side of the connecting rod away from the fixed pipe clamp.

[0011] In summary, the utility model has the following beneficial effects: As the connecting rod rotates, the movable pipe clamps between the same group of vertical plates move closer to the corresponding fixed pipe clamps together, enabling the clamping and fixing of multiple railings simultaneously, improving the construction efficiency of the guardrail and shortening the construction process. The elastic pads ensure the clamping force of the movable pipe clamps and the fixed pipe clamps on the railings. The connecting rod is located on the side of the fixed pipe clamp away from the bridge deck, reducing the contact between the connecting rod and people or objects inside the bridge. The limiting rod restricts the excessive movement of the connecting rod away from the fixed pipe clamp, facilitating the construction workers to grasp the end of the connecting rod to rotate the connecting rod.

[0015] The following combines the drawings and embodiments to describe the utility model in detail.

[0016] Embodiment: A bridge guardrail, as Figure 1 , Figure 2 shown, includes a plurality of railings 1 and a plurality of parallel vertical plates 2. The vertical plates 2 are grouped in pairs. A plurality of fixed pipe clamps 3 are fixedly connected between the vertical plates 2 of the same group. A connecting rod 4 is rotatably connected between the vertical plates 2 of the same group. A plurality of movable pipe clamps 5 are fixedly connected to the connecting rod 4. A pair of corresponding movable pipe clamps 5 and fixed pipe clamps 3 clamp a railing 1. Elastic pads 6 are fixedly connected to the inner side walls of the movable pipe clamps 5 and the inner side walls of the fixed pipe clamps 3.

[0017] Specifically, the bottoms of the vertical plates 2 of the same group are connected by a connecting plate. The two ends of the railing 1 are respectively located between two groups of vertical plates 2. The fixed pipe clamps 3 are welded to the vertical plates 2 on both sides of them. One end of any railing 1 corresponds to a fixed pipe clamp 3 and a movable pipe clamp 5. When the movable pipe clamp 5 and the fixed pipe clamp 3 are closed together, the railing 1 is clamped between the movable pipe clamp 5 and the fixed pipe clamp 3. A rotating shaft is welded between the two vertical plates 2 of the same group. One end of the connecting rod 4 is rotatably connected to the rotating shaft. The movable pipe clamp 5 is integrally formed with the connecting rod 4. Therefore, as the connecting rod 4 rotates, the movable pipe clamps 5 between the vertical plates 2 of the same group move closer to the corresponding fixed pipe clamps 3 together, enabling the clamping and fixing of multiple railings 1 simultaneously, improving the construction efficiency of the guardrail and shortening the construction process. The elastic pads 6 are made of rubber. The elastic pads 6 are connected to the movable pipe clamps 5 or the fixed pipe clamps 3 by bolts. The elastic pads 6 ensure the clamping force of the movable pipe clamps 5 and the fixed pipe clamps 3 on the railing 1.

[0018] As Figure 1 , Figure 2 shown, both the connecting rod 4 and the movable pipe clamp 5 are located on the side of the fixed pipe clamp 3 away from the bridge deck. A fixed block 7 is fixedly connected to the side wall of the same group of vertical plates 2. The end of the connecting rod 4 is detachably connected to the fixed block 7. A plug pin 8 is slidably connected to the fixed block 7. The plug pin 8 penetrates through the fixed block 7, the vertical plate 2, and the connecting rod 4 at the same time. A limiting rod 9 is fixedly connected between the same group of vertical plates 2. The limiting rod 9 is located on the side of the connecting rod 4 away from the fixed pipe clamp 3.

[0019] Specifically, a through hole is provided through the vertical plate 2 screw rod. A connecting ring is integrally formed at the end of the connecting rod 4. The fixed block 7 is located on both sides of the connecting ring. The through hole penetrates through the fixed block 7 and is coaxially arranged with the connecting ring. When the side wall of the fixed block 7 contacts the side wall of the connecting ring, the plug pin 8 is passed through the through hole to lock the rotation of the connecting rod 4 relative to the fixed pipe clamp 3, and the clamping of the railing 1 is completed. Both ends of the plug pin 8 penetrate through the two vertical plates 2 respectively. Nuts are threadedly connected to both ends of the plug pin 8, which is convenient for disassembling and assembling the plug pin 8. The connecting rod 4 is located on the side of the fixed pipe clamp 3 away from the bridge deck, reducing the contact between the connecting rod 4 and the people or objects inside the bridge. The limiting rod 9 limits the connecting rod 4 from moving too far away from the fixed pipe clamp 3, which is convenient for the construction personnel to grasp the end of the connecting rod 4 to rotate the connecting rod 4.

[0020] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
