Description

Technical Field

[0001] The utility model belongs to the technical field of guardrail plate equipment, in particular to a corrugated guardrail plate for expressways. Background Art

[0002] With the long-term rapid development of my country's economy, infrastructure construction has also developed faster and faster, especially highway construction, with longer and longer construction mileage, which has provided great convenience for automobile transportation. At the same time, with the substantial increase in the number of cars in the world year by year, the incidence of traffic accidents has also shown an upward trend year by year, and safe driving has become a problem that people are always concerned about. For cars driving on highways, due to the high speed, the anti-collision guardrails on both sides of the highway can effectively prevent the car from rushing out of the guardrail when a safety accident occurs, providing reliable safety protection for the driver and the hit vehicle. The existing highway anti-collision guardrail is mainly composed of columns and guardrail panels located on the upper part thereof. The columns and guardrail panels are both rigid materials. The car hits the guardrail panel to achieve the purpose of blocking the car, thereby reducing the serious consequences of traffic collision accidents.

[0003] At present, in order to ensure that the guardrail can have a good blocking effect on vehicles, the guardrail plate is generally set in a wave shape. While making the guardrail plate have a good buffering effect, it can also support it and ensure its stability. However, there are still some unreasonable things in the setting of the guardrail plate in the prior art, especially for the guardrail plate support between two adjacent columns, it is easy to have the possibility of vehicles rushing out, that is, its supporting strength is limited. In order to solve this problem, a common method is to install guardrail plates on both sides of the same column to play a double blocking role to a certain extent, thereby ensuring the use function. For the method of setting guardrail plates on both sides, the supporting strength of the guardrail plate area located between the two adjacent columns is still poor, and the effect of reducing the impact force caused by the collision is not good. In addition, this setting method only uses relatively simple bolts to connect the guardrail plate and the column. The tightness of the connection is insufficient. For some high-speed vehicles with large mass, when a collision occurs, especially for the connection between two adjacent guardrail plates, it is impossible to intercept the vehicle, so there is a possibility that the collided vehicle will rush out of the road, and even more serious consequences will be brought. Utility Model Content

[0004] In order to solve the technical problems of insufficient installation effect and supporting strength of the above-mentioned guardrail panels, the utility model proposes a corrugated guardrail panel for highways which has a reasonable design, a simple structure, is easy to process, and can effectively improve the supporting strength of the guardrail panel and the connection stability between various equipment components, enhance its impact resistance and buffering performance for vehicles, intercept colliding vehicles, and effectively meet the use requirements.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is a corrugated guardrail plate for highways, including two equidistantly arranged left and right columns, and wave-shaped guardrail plates are arranged on the front and rear sides of the columns, and bearing blocks are arranged on both sides of the outer periphery of the columns, and a support frame is arranged between two adjacent bearing blocks. A reinforcement frame is sleeved on the outer periphery of the bearing blocks, and the upper and lower halves of the reinforcement frame are both boomerang-shaped and made in one piece. A sleeve plate is arranged at the geometric center of one side of the reinforcement frame.

[0006] Preferably, a connecting plate is provided at the corner of one end surface of the reinforcing frame located near the side of the column, wherein one end surface of the connecting plate is designed to be flat, and the other end surface is designed to be arc-shaped and matched with the crest of the guardrail plate.

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Examples, such as Figure 1 to Figure 4As shown, a corrugated guardrail plate 2 for highways comprises two equidistantly arranged upright posts 1 on the left and right, and guardrail plates 2 with wavy designs are arranged on the front and rear sides of the upright posts 1. As for the establishment of the above-mentioned equipment components, it is an existing mature and commonly used technical means, which can be effectively known to the technicians in the relevant technical field, and the details are not repeated here. The present embodiment aims to solve the problem of insufficient supporting strength and connection strength of the existing guardrail plates 2. Specifically: bearing blocks 3 are arranged on both sides of the outer periphery of the upright posts 1, and a supporting frame 4 is arranged between two adjacent bearing blocks 3, wherein components for engaging with the bearing blocks 3 are arranged at both ends of the supporting frame 4, which improves the installation process of the equipment to a certain extent and reduces the labor intensity; further, a reinforcing frame is sleeved on the outer periphery of the bearing block 3. 5. The upper and lower halves of the reinforcing frame 5 are both designed in a boomerang shape and are made in one piece. A sleeve plate 51 is arranged at the geometric center of one side of the reinforcing frame 5. Specifically, the reinforcing frame 5 has a boomerang-shaped concave design at the geometric center, which can improve the deformation effect of the reinforcing frame 5 to a certain extent. That is to say, when a vehicle collides, its two ends can move toward the middle position, thereby providing a certain buffering effect for the colliding vehicle. Of course, the two side corners of the reinforcing frame 5 correspond to the wave crests of the guardrail plate 2, which provides convenient conditions for connecting it with equipment components. For the sleeve plate 51 set up, the lower end is designed to be open, the purpose of which is to provide a prerequisite for the reinforcing frame 5 to be installed on the bearing block 3, save installation time and cost, and improve the construction process.

[0020] In the above process: the support frame 4 is set up, which not only provides a convenient installation position for the guardrail panels 2 set up on both sides, but also has good buffering capacity, and its hollow design can drive the guardrail panels 2 to move toward the direction close to the geometric center of the column 1 when a collision occurs, thereby increasing the impact resistance of the anti-collision guardrail; the reinforcement frame 5 is set up, on the one hand, it has a good supporting and connecting effect to a certain extent, ensures the connection stability between the various equipment components, and prevents them from offsetting, and on the other hand, it also has a certain deformation ability, which is used to improve the impact resistance of the guardrail panels 2 and reduce the possibility of damage. At the same time, the alternating sleeve connection between the bearing block 3, the support frame 4 and the sleeve plate 51 greatly guarantees the connection stability, and to a certain extent reduces the possibility of deformation or breakage, ensuring the use requirements; the device is reasonably designed, simple in structure, easy to process, and can effectively improve the supporting strength of the guardrail panels 2 and the connection stability between the various equipment components, enhance its impact resistance and buffering performance on the vehicle, complete the interception of the colliding vehicle, and effectively meet the use requirements.

[0021] In order to effectively complete the stable connection between the support frame 4 and the guardrail board 2, a connecting plate 52 is provided at the corner of the end face of one side of the reinforcement frame 5 located near the side of the column 1, wherein one end face of the connecting plate 52 is designed to be flat, and the other end face is designed to be arc-shaped and adapted to the wave crest of the guardrail board 2. That is to say, after the sleeve plate 51 of the reinforcement frame 5 is sleeved on the bearing block 3, people use bolts to connect the support frame 4 and the reinforcement frame 5 together, and then people set up the guardrail board 2, especially ensuring that the wave crest on the inner side of the guardrail board 2 fits on the connecting plate 52. On the one hand, it ensures the tightness of the fitting between the equipment components, and on the other hand, it ensures the stability of the placement of the guardrail board 2, effectively improving its setting effect and meeting the use requirements.

[0022] In order to fully ensure that each equipment component can achieve stable cooperation, thereby to a certain extent playing a role in improving the stability of the connection between equipment, the bearing block 3 is designed in a U shape, which provides convenient conditions for the placement of the support frame 4 and improves the installation process. Furthermore, the support frame 4 is designed in a diamond shape, and its left and right ends are provided with adapter blocks 42 that engage with the bearing block 3, and a support rod 41 is provided at the geometric center of the support frame 4. It is specifically described as: the support frame 4 designed in a diamond shape not only provides a convenient installation position for the guardrail panels 2 set up on both sides, but also has good buffering capacity, and its hollow design can drive the guardrail panels 2 to move toward the direction close to the geometric center of the column 1 when a collision occurs, thereby increasing the impact resistance of the anti-collision guardrail, and effectively preventing the vehicle from colliding and causing the guardrail panel 2 to have a gap, causing the vehicle to fly out. At the same time, for the established support rod 41, the left and right sides of the support frame 4 can be divided into two triangular areas, which further increases the stability of the support frame 4 and has strong functionality.

[0023] In order to further improve the rationality of the establishment of the device and equipment, the upper end of the adapter block 42 protrudes from the bearing block 3 and abuts against the inner wall of the sleeve plate 51. That is to say, after the support frame 4 is established on the bearing block 3 between two adjacent columns 1, the sleeve plate 51 of the reinforcement frame 5 is sleeved on the bearing block 3. On the one hand, the stability of the support frame 4 is guaranteed. On the other hand, the upper end surface of the protrusion is flush with the upper end surface of the bearing block 3, which provides convenient conditions for abutting against the sleeve plate 51, greatly improves the contact tightness between the components of the device and equipment, and ensures the connection effect.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
