[0004] This patent realizes the rapid assembly of bridge parapets. After the bridge parapets are assembled, the parapets come into contact with objects when a collision occurs. However, the parapets are usually made of metal, so a collision may cause significant damage to both the parapets and the colliding objects, and the protective effect is low. After the parapets are installed between two columns, they are tightened and fixed by threaded pressure blocks. Bridge parapets are usually installed at a longer length, so a large number of screws need to be rotated, which is time-consuming and labor-intensive. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an assembled bridge parapet, which solves the problems of low protective performance and time-consuming and labor-intensive installation of the existing assembled bridge parapet.

[0006] To achieve the above purpose, the utility model is implemented by the following technical solutions: an assembled bridge guardrail includes two left and right bases, and columns are fixed on the tops of the two bases, a guardrail is assembled between the two columns, and the guardrail is compressed by a quick compression component after assembly, and a protective component for reducing collision damage is arranged in front of the guardrail;

[0007] The protection component includes a protection pad, and the protection pad cover is arranged in front of the guardrail. Two left and right first rubber belts are fixedly connected to the upper part of the back side of the protection pad, and two left and right second rubber belts are fixedly connected to the lower part of the back side. A plurality of mounting blocks are arranged at equal distances inside the second rubber belt, and a large-head buckle matching the mounting block is fixedly connected to the front side of the second rubber belt.

[0008] Preferably, the protective pad is composed of a hollow triangular prism, a hollow cuboid and a hollow cylinder, and the forward tip of the triangular prism is chamfered, and the hollow cylinder is fixed inside the hollow triangular prism.

[0009] Preferably, T-shaped grooves are provided on both the left and right sides of the upright posts, and T-shaped blocks are fixedly connected to both the left and right sides of the guardrail, so that the guardrail is inserted into the T-shaped groove between the two upright posts through the T-shaped blocks.

[0010] Preferably, the quick pressing assembly comprises a circular plate, positioning blocks are fixedly connected to both left and right sides of the circular plate, and a fan-shaped groove is formed on the top of the circular plate.

[0011] Preferably, a rotating rod is rotatably connected to the bottom of the inner wall of the fan-shaped groove, and a long strip is fixedly connected to the surface of the rotating rod.

[0012] Preferably, a groove matching the size of the circular plate is provided on the top of the base, two front and rear L-shaped grooves are provided on the surface of the base, and the L-shaped grooves are connected to the grooves, and the L-shaped grooves cooperate with the long strips.

[0013] Beneficial Effects

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The prefabricated bridge guardrail provides two technical solutions:

[0023] like Figure 1 and 2 The first embodiment is shown: it includes two left and right bases 1, and columns 2 are fixed on the tops of the two bases 1, and a protective component 4 for reducing collision damage is arranged in front of the guardrail 3;

[0024] The protection component 4 includes a protection pad 41, which is covered in front of the guardrail 3. Two left and right first rubber belts 42 are fixedly connected to the upper back of the protection pad 41, and two left and right second rubber belts 43 are fixedly connected to the lower back of the protection pad 41. A plurality of mounting blocks 44 are equidistantly provided inside the second rubber belt 43. A large-head buckle 45 matching the mounting block 44 is fixedly connected to the front of the second rubber belt 43. The protection pad 41 is composed of a hollow triangular prism, a hollow rectangular parallelepiped and a hollow cylinder. The forward tip of the triangular prism is chamfered, and the hollow cylinder is fixed inside the hollow triangular prism.

[0025] When a bridge guardrail collides, the protective pad 41 contacts the colliding object. The structure of the protective pad 41 can quickly disperse the collision force, reducing the damage to the guardrail and the colliding object caused by the collision. In addition, the protective component 4 can be quickly installed on the guardrail 3 through a rubber belt, thereby improving the practicability of the device when in use.

[0026] like Figure 1 and 3A second embodiment is shown, which mainly differs from the first embodiment in that a guardrail 3 is assembled between the two columns 2, and the guardrail 3 is clamped by a quick clamping assembly 5 after assembly, T-slots are provided on the left and right sides of the columns 2, and T-blocks are fixedly connected to the left and right sides of the guardrail 3, so that the guardrail 3 is inserted in the T-slot between the two columns 2 through the T-blocks, and the quick clamping assembly 5 includes a circular plate 51, and positioning blocks 52 are fixedly connected to the left and right sides of the circular plate 51, a fan-shaped groove 53 is provided on the top of the circular plate 51, and a rotating rod 54 is rotatably connected to the bottom of the inner wall of the fan-shaped groove 53, and a long strip 55 is fixedly connected to the surface of the rotating rod 54, a groove 56 matching the size of the circular plate 51 is provided on the top of the base 1, and two front and rear L-shaped grooves 57 are provided on the surface of the base 1, and the L-shaped groove 57 is connected to the groove 56, and the L-shaped groove 57 cooperates with the long strip 55.

[0027] After the guardrail 3 is assembled between the two columns 2, the guardrail 3 is compressed by the quick compression assembly 4. The compression only requires alignment and simple rotation, and the operation is convenient and quick.

[0028] When in use, the two columns 2 are placed or fixed through the base 1, and the guardrail 3 is inserted from above the two columns 2. After the guardrail 3 is inserted, the circular plate 51 is aligned with the groove 56 and inserted. After insertion, the long strip 55 enters the vertical part of the L-shaped groove 57, and then the rotating rod 54 is rotated. The rotating rod 54 rotates and drives the long strip 55 to rotate, so that the long strip 55 enters the horizontal part of the L-shaped groove 57, thereby completing the compression of the guardrail 3. In addition, the protective pad 41 is set to the front of the guardrail 3, and the large head buckle 45 on the second rubber belt 43 is clamped into the mounting block 44 in the first rubber belt 42. When a collision occurs, the structural design of the protective pad 41 can quickly disperse the collision force, thereby reducing the damage caused by the collision.
