Description

Integrated OSC modular mobile rigid protection fence with safety guidance system

[0001] The present invention relates to a mobile rigid protective fence with an integrated OSC safety guidance system.

[0002] A barrier is a facility that prevents vehicles from leaving the road and minimizes damage in the event of a vehicle collision. Depending on the installation location, it is classified into roadside, divider, sidewalk, and bridge use, and depending on the structural characteristics, it is divided into flexible barriers and rigid barriers.

[0003] The main function of a flexible barrier is to absorb impact energy while undergoing a certain range of structural deformation in the event of a vehicle collision. Representative examples include guardrails, guard pipes, and guard cables. On the other hand, a rigid barrier is a structure that focuses on minimizing deformation of the structure itself to guide the vehicle back to its path rather than absorbing impact. It is generally formed as an integral concrete structure.

[0004] The selection of the type of safety fence is determined based on the required safety performance criteria by comprehensively considering the road type of the installation site, traffic environment, type and speed of passing vehicles, etc. In general, the greater the structural rigidity, the better the escape protection performance of large vehicles, but the impact absorption performance is relatively low, which may reduce the passenger protection performance.

[0005] Accordingly, various structural improvement attempts are being made to achieve a balance between the vehicle's protective performance and the safety of passengers.

[0006] In addition, recently, there has been a growing demand for safety fences that go beyond simple physical collision prevention functions to include lighting functions that ensure visibility even at night and in bad weather conditions and provide clear road information to drivers. In particular, there is a growing demand for self-powered safety structures that can be operated by generating their own electricity, especially in areas where external power supply is difficult or where temporary installation is required.

[0007] In this regard, a prior art document for providing a protective fence that has excellent shock absorption capacity and rigidity to protect passengers, prevents secondary accidents caused by deformation of the central divider, and secures space for installing solar panels so that it can be used as a power source for various electrical appliances necessary for road safety includes "Vehicle protective fence equipped with a buffer member for attaching solar panels" (hereinafter referred to as "prior art") of Republic of Korea Patent Publication No. 10-2429514.

[0008] However, existing concrete material protective fences, including prior art ones, have been used by burying separate metal materials or reinforcing members inside the concrete for the purpose of improving protective performance or structural strength. However, since such reinforcement has been applied indiscriminately without comprehensively considering the shape, arrangement, and material characteristics related to structural performance, there has been a problem in which the performance improvement effect is minimal or the shock absorption performance is reduced due to fracture or scattering.

[0009] In addition, existing concrete material safety fences, including conventional technologies, are limited to structures that simply prevent the physical departure of vehicles, and thus do not provide sufficient visibility to road users in conditions where visibility is difficult to secure, such as at night or in bad weather. In addition, in places where power infrastructure is insufficient or where they are temporarily installed, it is difficult to supply power to operate the light-emitting function, requiring separate lighting devices or infrastructure.

[0010] The present invention was created to solve the above problems, and the purpose of the present invention is as follows.

[0011] First, the purpose is to provide a movable rigid safety fence that can prevent vehicle departure and induce stable vehicle behavior after a collision by securing strength performance and deformation performance in the event of a collision through the specification of the structure and specifications for each component.

[0012] Second, the purpose is to provide a protective fence with improved safety in terms of the degree of scattering and the distance of discharge of scattering products by optimizing the structural joint form and the arrangement conditions of components to minimize scattering due to breakage or detachment of components upon impact.

[0013] Third, the purpose is to provide a protective barrier that can reduce injuries to passengers and improve safety within the vehicle in the event of a collision through the dissipation characteristics of collision energy and the shape design of the protective structure.

[0014] Fourth, the purpose is to provide a protection system that can secure stable visibility and improve the efficiency of maintenance even in road environments with insufficient power infrastructure by configuring the lighting function to operate autonomously through a self-power generation module utilizing solar energy without a separate external power supply.

[0037] A preferred embodiment of the present invention will be described in more detail with reference to the attached drawings, but already well-known technical parts will be omitted or compressed for the sake of brevity.

[0038] 1. Description of the composition and structure of the OSC modular movable rigid protective fence with integrated safety guidance system.

[0039] Referring to FIGS. 1 and 2, the OSC modular movable rigid protective fence (10) integrated with a safety guidance system of the present invention is a protective structure that can secure visibility in a road environment and at the same time secure structural safety at a high level by utilizing light output through self-power generation without external power through solar power generation, and is configured to include a plurality of protective blocks (100) corresponding to protective units arranged in the longitudinal direction of the front and rear; a connecting device (200); a steel bar member (300); and a light-emitting module (400); so that the protective units arranged in the longitudinal direction of the front and rear are connected, thereby enabling the construction of a long protective structure.

[0040] In this regard, since the entire system of the present invention is designed and configured based on the OSC (Off-Site Construction) concept, all major components, such as the protective block (100), the light-emitting module (400), and the steel bar member (300), are precisely manufactured as pre-standardized units at the factory, so that they can be quickly installed and assembled on site without separate processing or electrical wiring work.

[0041] In particular, since the light emitting module (400) is integrated and built into the unit or assembled through a standardized interface, quality deviations due to technical differences between installation personnel or environmental variables can be reduced, and the durability and construction precision of each component are also improved.

[0042] Furthermore, the connecting device (200) of the present invention is designed to easily connect multiple protective blocks in the front-back direction, which enables the repeatability of modular assembly and disassembly, which is the core of the OSC method. In other words, the present protective fence system is structured to allow easy separation or replacement of certain sections even after initial installation, and to allow for repeated transport, loading, and reinstallation in module units, thereby excelling in terms of ease of maintenance, space efficiency, and flexibility in long-term operation.

[0043] In addition, it provides flexibility and mobility to respond immediately to frequent lane changes, temporary control zone establishment, and maintenance infrastructure improvement work that occur in road environments, and this provides a great advantage in terms of efficient operation of public roads and maintenance of traffic flow compared to fixed protective structures.

[0044] Ultimately, the present invention goes beyond simple protection performance and achieves technological perfection as a smart infrastructure-type protection system that combines an OSC-based construction strategy and energy-independent luminous function.

[0050] Specifically, based on 1270 mm corresponding to the vertical reference height (H) of the protective block body (110), the first body part (111) corresponds to an area up to a height (Ha) of 135 mm to 140 mm (most preferably 138 mm), the second body part (112) corresponds to an area having a height (Hb) of 160 mm to 170 mm from the top of the first body part (111) (most preferably 166 mm), and the third body part (113) corresponds to an area having a height (Hc) of 960 mm to 970 mm from the top of the second body part (112) (most preferably 966 mm).

[0051] In addition, the second body part (112) is formed so that the part connected to the upper end of the first body part (111) at the lower end has a curvature of R150 on the outside, and the part connected to the lower end of the third body part (133) at the upper end has a curvature of R260 on the inside.

[0053] The features regarding the structure and specifications of the protective block body (110) correspond to specific features for providing a high level of protective performance through fusion with other configurations to be described later.

[0054] And, in order to achieve connection between a plurality of protective blocks (100) arranged adjacently in the front and rear using a steel bar member (300), a connection member installation groove (110H) is provided on the inside (towards the bottom in the case of the front end, towards the front end in the case of the rear end) at the front and rear ends of the protective block body (110), as shown in FIGS. 2, 4, and 7.

[0056] 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).

[0063] In addition, the second reinforcing member (122) is spaced apart from each other at equal intervals in the vertical direction perpendicular to the column portion (121b) of the first reinforcing member (121), and the distance (D4) at which the two are spaced apart at equal intervals is set to 290 mm to 310 mm.

[0064] Through this, a plurality of square frames forming a plurality of rows and columns are provided through orthogonal cross-connections (interconnected through welding depending on the implementation) of the column portion (121b) of the first reinforcing portion (121) and the second reinforcing portion (122), thereby forming a grid-like reinforcing structure on both left and right sides of the reinforcing structure (120).

[0065] Specifically, among the plurality of square frames formed through the orthogonal cross-connection of the column portion (121b) of the first reinforcing member (121) and the second reinforcing member (122), the square frames of the front row and the rear row based on the front-back direction are provided with a front-back reference length (D3) of 460 mm to 465 mm (most preferably 462.5 mm), and the square frames of the remaining rows among the plurality of square frames are provided with a front-back reference length (D2) of 580 mm to 620 mm (most preferably 600 mm).

[0077] In addition, in the process of performing the fastening between a plurality of protective blocks (100) adjacently arranged in the front and rear using a reinforcing member (300), it is preferable that the installation positions of the front end of the first reinforcing member (130) arranged in front of the protective block body (110) and the first reinforcing member (130) arranged in the rear of the protective block body (110) do not overlap and are spaced apart from each other at equal intervals along the height in order to prevent the first eye bolt portion (142) of the first fastening member (140) coupled to the end of the first reinforcing member (130) from colliding with each other.

[0078] In addition, the second reinforcing member (150) is a plurality of reinforcing bar structures made of a '-' structure using reinforcing bars having a reinforcing bar diameter of 26 mm to 32 mm (most preferably D29 standard), and as shown in FIG. 3, it is installed on the upper side of the protective block body (110) from the front to the rear of the protective block body (110) so as to be positioned at the center of the left and right directions of the protective block body (110).

[0079] In connection with this, a second fastening member (160) is connected to the front and rear ends of the second reinforcing member (150) using a connecting device (200) to fasten a plurality of protective blocks (100) arranged adjacent to each other in the front and rear.

[0083] According to the implementation, the second coupler part (161) and the second eye bolt part (162) have a one-touch coupler type fastening structure so that when connected, the second eye bolt part (162) is pushed toward the second coupler part (161) to fasten at once, and the connection is not easily disconnected.

[0084] Accordingly, the connecting device (200) that performs the connection by connecting one end of a front-end side protective block (100) among a plurality of adjacently arranged protective blocks (100) and the other end of a rear-end side protective block (100) includes a pair of connecting bodies (210), a pair of fastening plate structures (220), an upper plate structure (250), a first fastening member (230), and a second fastening member (240) as shown in FIGS. 2 and 6 to achieve connection using a connecting device installation groove (115H) and a second eye bolt portion (162).

[0085] Here, a pair of connecting bodies (210) are provided in a '┌┐' structure and are placed at the front and rear of each position where a pair of connecting device installation grooves (115H) are provided on the outer upper surface of the protective block body (110).

[0086] Through this, a pair of connecting bodies (210) are installed so that the lower part of the pillar portions placed vertically on the '┌┐' structure of the connecting body (210) covers the left and right ends of the connecting device installation groove (115H) as shown in FIGS. 2 and 6.

[0087] Next, the upper plate structure (250) is a plate structure arranged so that one end covers the upper surface of a connecting body (210) arranged on the rear end of one protective block (100) on the front side among a plurality of protective blocks (100) arranged adjacently in the front and back as shown in FIG. 6, and the other end covers the upper surface of a connecting body (210) arranged on the front end of another protective block (100) on the rear side among a plurality of protective blocks (100) arranged adjacently in the front and back.

[0089] In addition, the first fastening member (230) is configured for coupling between the upper surface of a pair of connecting bodies (210) and the upper plate structure (250) as shown in FIGS. 2 and 6, and is composed of a first connecting bolt portion and a first nut portion.

[0090] Specifically, the first connecting bolt portion of the first fastening member (230) is installed so as to penetrate the front and rear ends of the upper plate structure (250) and the upper surface of the connecting body (210) from the outside, and a first nut portion is fastened to both ends of the first connecting bolt portion installed in this manner.

[0091] Lastly, the second fastening member (240) is configured for connection between the lower left and right sides of a pair of connecting bodies (210), a pair of fastening plate structures (220), and the upper part of the protective block body (110), as shown in FIGS. 2 and 6, and is composed of a second connecting bolt portion and a second nut portion.

[0092] Specifically, the second connecting bolt portion of the second fastening member (240) is installed so as to penetrate the front and rear ends of the fastening plate structure (220) from the outside, the left and right ends of the connecting body (210), the connecting device installation groove (115H), and the connecting bolt insertion hole (162H) of the second eye bolt portion (162), and the second nut portion is fastened to both ends of the second connecting bolt portion installed in this manner.

[0093] According to the implementation, the protective block (100') may further include a first metal wire member (170') and a second metal wire member (180') to prevent it from being broken more easily upon collision with a vehicle, to prevent it from being pushed backwards by a certain distance due to a vehicle collision, and to prevent flying debris such as concrete fragments from being generated more upon collision with a vehicle and from flying far even if they are generated.

[0094] Specifically, as illustrated in FIG. 8, inside the concrete protective block body (110') corresponding to the basic structure of the protective block (100'), the protective performance improvement structure by the first reinforcing member (121') and the second reinforcing member (122') corresponding to the same as described above and the protective performance improvement structure by the first reinforcing member (130') and the second reinforcing member (150') are linked, and the first metal wire member (170') and the second metal wire member (180') are extended and wound in the longitudinal direction along the outer periphery of the first reinforcing member (130') and the second reinforcing member (150') can achieve a more reliable and advanced improvement in protective performance.

[0095] Here, the first metal wire member (170') is configured to be wound in a spring shape on the outside of a plurality of first reinforcing members (130') so that each of the plurality of first reinforcing members (130') is arranged at the center inside, and welding is performed at any number of points through a connecting bar in which one end is connected to the outside of the first reinforcing member (130') and the other end is connected to the inside of the first metal wire member (170') in order to be interconnected while the first reinforcing member (130') is arranged at the center.

[0096] More specifically, the first metal wire member (170') is a wire member having a diameter of 4 mm to 5 mm (most preferably 4.5 mm), and the diameter of the spring-shaped member formed by winding around the outer side of each of the plurality of first reinforcing members (130') is provided to be 190 mm to 210 mm (most preferably 200 mm).

[0097] In addition, the second metal wire member (180') is configured to be wound in a spring shape on the outside of a plurality of second reinforcing members (150') so that each of the plurality of second reinforcing members (150') is arranged at the center inside, and welding is performed at any number of points through a connecting bar in which one end is connected to the outside of the second reinforcing member (150') and the other end is connected to the inside of the second metal wire member (180') in order to be interconnected while the second reinforcing members (150') are arranged at the center.

[0098] More specifically, the second metal wire member (180') is a wire member having a diameter of 4 mm to 5 mm (most preferably 4.5 mm), and the diameter of the spring-shaped member formed by winding around the outer side of each of the plurality of second reinforcing members (150') is provided to be 190 mm to 210 mm (most preferably 200 mm).

[0099] Meanwhile, the light-emitting module (400) is installed on the lower side of at least one of the left and right widthwise sides of the protective block (100) as shown in Fig. 1 and provides a light source when in operation.

[0100] More specifically, the light emitting module (400) is installed in a form built into an installation groove or a sunken receiving space formed on the outer surface of the upper side or the central part of the protective block (100), and the light output direction of the light emitting module (400) is arranged horizontally or at a certain angle with respect to the side of the protective block (100), so that it can output irradiation light toward the roadway direction when in operation.

[0101] To this end, the light emitting module (400) is provided with a module body (410), a light emitting unit (420), and a self-generating unit (430) as shown in Fig. 1.

[0102] Here, the module body (410) corresponds to a body housing installed on at least one side of the left and right width directions of the protective block body.

[0103] Next, the light emitting unit (420) is configured to be installed in the module body (410) and output a light source, and includes an LED-based light emitting element. The irradiation angle is adjusted to form along the road surface or the road edge, so that a constant band of light can be formed along the driving path of the vehicle. The brightness and lighting pattern are designed in consideration of the continuity and illuminance between a plurality of light emitting modules spaced apart at a constant interval.

[0104] In addition, a light-transmitting cover having heat resistance and impact resistance is fixedly installed on the module body (410) to prevent damage to the light-emitting part (420) exposed to the outside from vehicle impact, contact with flying objects, contaminants, etc.

[0105] In addition, the light emitting unit (420) receives direct current power supplied from a self-generating unit (430) to be described later, and lighting or blinking control is performed by a light emitting control circuit.

[0106] Lastly, the self-generation unit (430) is installed on one side of the module body (410) to generate electricity by generating electricity using solar energy, and supplies the generated electricity as operating power for the light-emitting unit (420).

[0107] More specifically, the installation surface of the self-generating unit (430) is designed to have a predetermined inclination angle with respect to the road direction or south direction to secure solar radiation.

[0108] Depending on the implementation, the self-generating unit (430) may be composed of a crystalline silicon cell or a thin-film cell based on a polymer film, and has a structure that absorbs natural light during the daytime to generate direct current power.

[0109] In this regard, the self-power generation unit (430) includes a photovoltaic structure that converts light energy into electrical energy based on the photoelectric effect, and various materials and manufacturing technologies can be applied depending on the cell configuration method.

[0110] For example, it may include crystalline silicon solar cells using monocrystalline silicon or polycrystalline silicon, which can secure high efficiency (approximately 18 to 22%) and long-term durability, making them suitable for outdoor structures.

[0111] Additionally, considering flexibility such as installation conditions and curved surface attachment, CIGS (Cu-In-Ga-Se) thin-film solar cells, CdTe (Cadmium Telluride) solar cells, and a-Si (amorphous silicon)-based thin-film solar cells can also be applied.

[0112] Although these thin-film cells have relatively low efficiency (approximately 10-15%), they are lightweight, inexpensive, and can be applied to flexible substrates, making them easy to apply to curved or irregularly shaped protective structures.

[0113] Additionally, cells utilizing next-generation high-efficiency materials, such as perovskite solar cells or carbon nanotube-based organic solar cells, may also be considered in recent years, and these cells have the potential to generate high-output power even in limited areas due to their high absorption coefficient and flexibility.

[0114] In this case, the self-generating unit (430) is applied with an anti-reflection coating (ARC), surface texturing, and a multi-layer thin film stacking structure to increase light receiving efficiency, and the generated power is collected in module units through the internal electrodes of the cell and output in the form of a direct current voltage.

[0115] In another way, the self-generating unit (430) can be laminated with an EVA encapsulation layer for waterproofing and dustproofing, a tempered glass or flexible polymer cover layer, a rear backsheet, etc. to ensure durability against external impact, moisture, ultraviolet rays, etc., and the resulting DC power can be stably supplied to the light-emitting unit (420) through a power conversion circuit with an MPPT (Maximum Power Point Tracking) function.

[0116] The power generated in this way is regulated to a stabilized voltage and current through a power conversion circuit provided inside the self-generating unit (430) or in a separate connection unit, and then transmitted to the light-emitting unit (420) through a power supply line or an internal power connection line.

[0117] At this time, in order to secure an imbalance in the output power or nighttime illumination, a small secondary battery (e.g., lithium ion battery) or supercapacitor for power storage may be configured in conjunction with the self-generating unit (430), through which the power charged during the day can be continuously supplied to the light-emitting module even at night or in low-light conditions.

[0118] Furthermore, the self-power generation unit (430) is provided with a protective cover having waterproof and dustproof functions to prevent damage or contamination by the external environment, and an ultraviolet-reducing film or anti-reflective coating can be applied to maintain power generation efficiency even in a long-term exposure environment.

[0119] Through this, the light-emitting module (400) can provide a visual guidance effect to road users even in low-light environments such as day and night or in bad weather, and can contribute to preventing vehicles from leaving the road and ensuring safety.

[0121] 2. Description of the performance test of the OSC modular mobile rigid protective fence with integrated safety guidance system.

[0122] The tests below were conducted to examine safety in the event of a vehicle collision by performing a collision simulation based on the OSC modular movable rigid protective fence (10) integrated with a safety guidance system 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.

[0123] Here, the plurality of protective blocks (100) of the OSC modular mobile rigid protective fence (10) integrated with the safety guidance system 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.

[0124] 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).

[0125]

[0126] (1) Strength performance evaluation

[0127] The results of the strength performance evaluation are as shown in Table 1 below.

[0128] 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.

[0129] As shown in Table 1, the final deformation of the OSC modular movable rigid protective fence (10) integrated with the safety guidance system 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 on the center of the vehicle protective fence, 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 violated based on the vehicle's travel path.

[0130] In addition, no abnormal behavior such as vehicle overturning was observed in the overall collision behavior, and the main damage to the OSC modular mobile rigid protective fence (10) integrated with the safety guidance system 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.

[0131]

[0132] (2) Passenger protection performance evaluation

[0133] The results of the passenger protection performance evaluation are as follows in Table 2.

[0134] 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.

[0135] As shown in Table 2, the THIV, which is the passenger safety index of the OSC modular mobile rigid protective fence (10) with integrated safety guidance system 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.

[0136] As a result, it can be seen that the OSC modular mobile rigid protective fence (10) with integrated safety guidance system according to the invention has a considerably high level of protective performance based on the characteristics of the specific structure and specifications of the detailed configuration when based on a plurality of protective blocks (100), and further, when the first metal wire member (170') and the second metal wire member (180') 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.

[0137] 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.
