Description

Roadside mobile rigid barrier with attached connecting device

[0001] The present invention relates to a movable rigid protective fence for roadside use.

[0002] The types of safety fences are classified into roadside, divider, sidewalk, and bridge types depending on the location where the facility is installed, and can be classified into flexible and rigid types depending on the strength of the facility.

[0003] Among these, the main function of the flexible safety barrier is to absorb impact energy while undergoing some deformation when a vehicle collides, and includes guardrails, guard pipes, and guard cables.

[0004] In addition, a rigid barrier refers to a barrier that is constructed with a non-deforming structure for the purpose of returning a vehicle rather than absorbing shock due to deformation of the structure, and is generally constructed with a single-body concrete structure.

[0005] Consequently, the type of barrier is selected based on the standards for required performance, taking into account the road and traffic characteristics of the installation site.

[0006] The greater the structural rigidity of these safety barriers, the more effective they are in protecting large vehicles. However, their impact-absorbing capacity is relatively low, which can be insignificant in terms of passenger safety. Therefore, comprehensive and balanced consideration is required regarding both the vehicle's protective performance and the passenger's safety performance.

[0007] Accordingly, various attempts are being made to reinforce the structural safety and performance of safety fences within the framework of lane departure protection for large vehicles and reduction of damage to passengers in small vehicles.

[0008] As an example, various technologies are being developed to improve protective performance by burying separate members inside a rigid protective fence based on a concrete structure, and in relation to this, a prior art document for providing a movable protective wall that can strengthen the bonding force in the event of a vehicle collision and facilitates bonding and dismantling operations is disclosed in Korean Patent Publication No. 10-2013-0071352 entitled “Method for Manufacturing a Movable Protective Wall and Protective Blocks for a Movable Protective Wall” (hereinafter referred to as “prior art”).

[0009] However, existing concrete material protective fences, including prior art, have a problem in that, in the process of burying separate members inside the concrete structure in an attempt to improve strength or protective performance, specific structures and specifications are not comprehensively considered in relation to performance, but are simply indiscriminately reflected, resulting in a decrease in performance improvement or a minimal level.

[0010] In addition, existing concrete material protective fences, including prior art ones, have a problem in that, even though separate materials are embedded inside the concrete structure in an attempt to improve strength or protective performance, the embedded materials become more easily broken or deformed by impact, or the degree of scattering becomes worse.

[0011] The present invention was created to solve the above problems, and the purpose of the present invention is as follows.

[0012] First, the purpose is to provide a roadside mobile rigid barrier that improves performance related to strength performance, deformation performance, and vehicle behavior after collision by specifying the structure and specifications for each component.

[0013] Second, the purpose is to provide a roadside mobile rigid protective fence that improves the level of scattering and the distance of discharge of flying materials in relation to the scattering of component parts by specifying the structure and specifications for each component.

[0014] Third, the purpose is to provide a roadside mobile rigid safety fence that improves passenger protection performance and vehicle safety performance after a collision by specifying the structure and specifications for each component.

[0049] Next, the reinforcing structure (120) is a structure made of steel bars and is embedded with a specific structure inside the protective block body (110) to provide structural reinforcement. The level of structural reinforcement can be greatly improved through the specific structure constructed through the first reinforcing part (121) and the second reinforcing part (122).

[0090] 2. Description of performance test of movable rigid barrier for roadside use

[0091] The following tests were conducted to examine safety in the event of a vehicle collision by performing a collision simulation based on the roadside mobile rigid protective fence (10) according to the present invention, which is composed of a plurality of protective blocks (100); a connecting device (200); and a steel bar member (300); as described above, and in which the protective blocks (100) are connected and connected along the longitudinal direction in the front and rear directions.

[0092] Here, the plurality of protective blocks (100) of the road-side movable rigid protective fence (10) to be inspected include a protective block body (110), a reinforcing structure (120), a first reinforcing member (130), a second reinforcing member (150), a first fastening member (140), and a second fastening member (160), and are manufactured in accordance with the most desirable specifications and structural conditions described above.

[0093] Specifically, the test items were strength performance for large vehicle collisions and passenger safety for small vehicle collisions. The review method was to conduct a crash simulation considering SB1 class crash conditions in accordance with the performance evaluation method of vehicle safety fences in the Road Safety Facility Installation and Management Guidelines (Ministry of Land, Infrastructure and Transport, 2014) and the Vehicle Protection Safety Facility Real Vehicle Crash Test Work Manual (Ministry of Land, Infrastructure and Transport, 2015).

[0094] (1) Strength performance evaluation

[0095] The results of the strength performance evaluation are as shown in Table 1 below.

[0096] Item Performance Standard Simulation Results Structural Performance Strength Performance Strength will be maintained Has strength that trucks will not break through. Deformation Performance <Maximum Deformation> Concrete foundation: 0.3 m or less Pillars embedded in the soil: 1.0 m or less Maximum Deformation: 0.26 m Maximum Occupancy Width: 0.26 m Behavior of the vehicle after collision There will be no overturning of the vehicle The center of gravity of the vehicle will not invade the center line of the safety fence Escape Box Escape into the box Component Scatter Component members will not scatter onto or off the road and cause harm to passengers or third parties There will be no large scattering of component members in the event of a vehicle collision.

[0097] As shown in Table 1, the final deformation of the road-side movable rigid barrier (10) according to the present invention was 0.26 m, and the maximum width of the vehicle during the collision was 0.26 m. Accordingly, the center of gravity of the colliding vehicle did not infringe upon the center of the vehicle barrier, and although the wheels of the vehicle did not completely leave the escape box during the analysis time, it was predicted that the boundary would not be infringed upon based on the vehicle's travel path.

[0098] In addition, no abnormal behavior such as vehicle overturning was observed in the overall collision behavior, and the main damage to the roadside mobile rigid protective barrier (10) according to the present invention after a collision with a large vehicle was that a tensile crack occurred on the opposite side of the collision of the protective block (100) that initially collided, and only partial damage to the concrete occurred at the end of the protective block (100) near the collision site.

[0099] (2) Passenger protection performance evaluation

[0100] The results of the passenger protection performance evaluation are as follows in Table 2.

[0101] Item Performance Standard Simulation Results Occupant Protection Performance THIV 33km / h or less 19.5km / h PHD 20g or less 7.7g ASI (reference) 0.98 Vehicle Safety Performance after Collision There will be no vehicle overturning, etc. The rotation angle of Roll and Pitch will be 75° or less Roll: 4.9°, Pitch: 8.6° Escape Box Escape within the box Component Flying Component parts will not fly onto or off the road and cause harm to passengers or third parties. No large flying of component parts can be seen in the event of a vehicle collision.

[0102] As shown in Table 2, the THIV, which is the passenger safety index of the road-side mobile rigid barrier (10) according to the present invention, was 19.5 km / h, which is below the performance standard of 33 km / h, and the PHD was 7.7 g, which is below the performance standard of 20 g. The ASI used in the European standard was 0.98. Accordingly, the maximum rotation angle of the vehicle during the collision was Roll: 4.9°, Pitch: 8.6°, which is below the performance standard of 75°. The escape box for evaluating the vehicle behavior after the collision showed that the vehicle's wheels were separated into the escape box, and no abnormal behavior such as the vehicle overturning was observed in the overall collision behavior.

[0103] As a result, it can be seen that the roadside mobile rigid protective fence (10) according to the invention has a considerably high level of protective performance based on the specific structural and standard characteristics of the detailed configuration when based on a plurality of protective blocks (100), and further, when the first metal wire member (700') and the second metal wire member (800') are further added according to implementation, not only the degree of rigidity but also the degree of scattering and the degree of scattering distance can be further reliably improved.

[0104] The embodiments disclosed in the present invention are intended to illustrate, not limit, the technical concepts of the present invention. These embodiments do not limit the scope of the technical concepts of the present invention. The scope of protection should be interpreted according to the following claims, and all technical concepts within the scope equivalent thereto should be construed as being included within the scope of the present invention.
