Description

Bending joint type low profile movable barrier

The present invention relates to a barrier disposed at the center of the road, the roadside, bicycle lanes, construction section, confluence of traffic flows and junctions, and more specifically, when the vehicle collides, the vehicle safely turns and returns to the driving lane when the vehicle collides. Initially, the connection parts of the barrier bodies connected to each other are deflected, which reduces the impact force transmitted to the crashing vehicle and the occupant, thereby reducing damage to the crashing vehicle and the occupant, and lowering the barrier height, but Make sure that the crash vehicle is no higher than the center of the vehicle's wheels so that the crash vehicle does not cross the barrier and invade other roads, such as the other side of the road, roadside, bike path, work zone, or sidewalk. With vehicles or bicycles and passengers driving A refractive-connected so as to prevent the serious accident caused by a secondary collision against the pedestrian or construction zones worker walking to Figure relates to a low hyeonggo movable barrier.

In general, road boundaries, such as the median of roadways, roadsides, or roads of different types (such as India and driveways, driveways and bicycle paths), prevent vehicles leaving the lane from crossing the road boundaries and drive the vehicle in the original direction. A barrier is provided to guide the return to the furnace.

Conventional barriers are classified into fixed barriers and movable barriers according to the installation state.

The fixed barrier is fixedly installed on the ground of the road, and the pavement can be perforated to purchase the props, thereby damaging the pavement surface, and the pavement can be damaged by freezing and thawing due to the inflow of running water. It is a type that can be installed on the move without damaging the pavement surface and bendable to each other.

The fixed barrier is mainly installed on the central separator or the furnace side, and the movable barrier can be installed at a desired place as needed and can be moved when necessary.

The concrete fixed barrier has a problem that serious damage to the crash vehicle and the occupant because it does not contain a factor to alleviate the impact force when the vehicle collides with the constraint that the mobile installation barrier is impossible.

Referring to the movable barrier in the context of the present invention, the movable barrier is installed in succession of unit barriers having a unit length (for example, 1000mm to 4000mm) along the central divider or roadside, between the driveway and the bicycle road or the entire boundary between the driveway and the sidewalk. Alternatively, two or more unit barriers may be provided at regular intervals.

In the case where the unit barriers constituting the movable barrier are independently installed without being connected to each other, when the vehicle collides with each other, the collision force is resisted by the resistance according to the weight of the unit barrier in which the vehicle collides.

Therefore, if a vehicle collides with one or two unit barriers, depending on the collision angle, the unit barrier is easily pushed out, and not only does it prevent the crash vehicle from returning to the original driving road, but in severe cases, the collision vehicle rides on the unit barrier. In this case, there is a problem that the crash vehicle is collided with the pedestrians walking on the opposite side of the road or roadside or cyclists and riders or pedestrians walking on the road, causing serious accidents.

Also, in the related art, a fixed connection movable barrier having a plurality of unit barriers connected thereto is known.

These conventional movable barriers are products that use water or sand in concrete and plastic barrels. In the case of concrete barriers, the connection is weak and the connection is cut when the vehicle crashes. This is difficult. In the case of a plastic barrier, it is easy to break during a vehicle crash, and water or sand leaks, and thus the protection function is lost, and maintenance is difficult.

Accordingly, an object of the present invention is to reduce the impact force transmitted to the crash vehicle and the occupant at the beginning of the crash, while ultimately returning or stopping the crash vehicle to the original driving road when the vehicle collides, thereby preventing damage to the crash vehicle and the occupant. It is to provide an articulated low-moving barrier that can be reduced and prevents road pavement damage.

Another object of the present invention is that after the deflection angle of the connected unit barrier is deflected by the set angle, the entire connected plurality of unit barriers, which are no longer refracted, act as a counter element to the impact force and return the crash vehicle to the original driving road. It is to provide an articulated low-moving barrier that can be stopped or stopped.

Still another object of the present invention is to provide a refractive connection type low and movable barrier that can adjust the rigidity of the barrier according to the place where the barrier is installed by adjusting the impact force reduction and deformation due to the vehicle collision according to the connection method and the fastening method. will be.

[Example 5]

34 to 41 show a fifth preferred embodiment of the articulated low type high mobility barrier according to the present invention.

As shown in FIGS. 34 to 37, the refractive connection type low height movable barrier according to the present embodiment is different from the refractive connection means, and the barrier body 10 and the refractive angle limiting means are different from those of the first embodiment described above. Since it is the same, the same code | symbol is attached | subjected about the same part and detailed description is abbreviate | omitted.

The articulation connecting means of the articulated low type high movable barrier according to the present embodiment is perpendicular to the upper protrusion connecting portion 101 and the upper protrusion connecting portion 101 extending from the upper end of the front surface 11 side of the barrier body 10. A first refractive connection member (100) having a pin hole (102) bored therein; The second articulation connecting member 110 includes a lower protruding connector 111 extending from the lower half of the rear surface 12 side of the barrier body 10 and a pin hole 112 vertically drilled into the lower protruding connector 111. ) And; It includes a connecting pin 120 that is fitted to the pin hole 102, 112 of the first and second refractive connection member 100, 110.

In addition, the refractive connection means includes a gap (C11) formed between the pin hole 102, 112 and the connecting pin 120.

As shown in FIG. 35, the first unit barrier B1 to be disposed on the left side is seated on the ground of the road boundary, and the second unit to be disposed on the right side, as shown in FIG. 35. The barrier unit B2 is moved above the right side of the first unit barrier B1 to form a second unit barrier on the first protrusion connecting portion 101 constituting the first refractive connection member 100 of the first unit barrier B1. The second protruding connecting portion 111 constituting the second refractive connecting member 110 of B2 is placed thereon.

The pin holes 102 and 112 of the first protrusion connecting portion 101 and the second protrusion connecting portion 111 are positioned on the coaxial line, and the connecting pin 120 is inserted into the pin holes 102 and 112.

At this time, a gap C11 is formed between the pin holes 102 and 112 and the connection pin 120.

As described above, the refractive connection type low type high mobility barrier according to the present embodiment includes a first protruding portion 101 in which the first unit barrier B1 and the second unit barrier B2 constitute the first refractive connection member 100. And a second protruding connecting portion 111 and a connecting pin 120 constituting the second refractive connecting member 110 so as to be refracted in the horizontal direction, and the first protruding connecting portion 101 and the second protruding connecting portion ( Since the clearance C11 is formed between the pin holes 102 and 112 and the connecting pin 120 drilled in the 111, as shown in FIG. 41 at the initial collision of the vehicle, the first unit barrier B1 and the first unit barrier B1 are formed. The two-unit barrier B2 deflects in the horizontal direction at its connection to reduce the impact force transmitted to the crash vehicle and the occupant at the beginning of the crash.

Meanwhile, as shown in FIG. 46, the conventional movable barrier is configured to have a trapezoidal cross section with a wide base 210 and a narrow top 220.

Since the conventional movable barrier is configured to have a narrower cross-sectional area toward the top, the height Hc of the collision point Pc of the wheel 1 of the crash vehicle is the height Ho of the center O of the wheel 1. The lower position will cause the wheel 1 to cross the barrier 200, in which case the vehicle will break out of the boundary of the road and invade other roads, causing secondary collisions with vehicles or pedestrians driving on other roads. There is a problem that causes a serious accident.

In addition, in the construction of the conventional mobile barriers described above, the mobile barriers 200 and 300 are configured to be narrowed toward the upper side by combining the tongs with a crane, an excavator, and the like to lift and transport both sides with the tongs. Therefore, a slip phenomenon occurs between both sides of the barriers 200 and 300 and the tongs are not caught firmly when transporting the tongs together with a crane or an excavator, which may cause a safety accident due to the fall of the barrier. have.

In order to solve the problem of the conventional movable barrier, it can be considered that the bottom side 310 and the top side 320 have the same square cross-section, but in this case, the height Hc of the collision point Pc is the wheel 1. Since it is the same as the height Ho of the center of the (O), it can be less than the conventional movable barrier 200 shown in Figure 47, but the problem that the wheel 1 is over the barrier 300 is enough There is a problem that cannot be solved.

In addition, when a pair of tongs are coupled to a crane or an excavator, the two sides of the tongs are lifted and transported, so that both sides are parallel vertical planes, so that a slip phenomenon occurs between both sides of the barrier 300 and the tongs, thereby coupling the tongs to a crane or an excavator. There is a problem that there is a risk that a safety accident due to the fall of the barrier is not firmly caught in the transport.

Accordingly, in the articulated low type high movable barrier according to the present invention, the height Hc of the collision point Pc of the wheel 1 of the collision vehicle is located at the left and right sides of the barrier body 10. And an undercut portion U that is higher than the height Ho and lower than the top height Ht of the left and right sides 15 and 16.

As shown in Fig. 42, the undercut portion U can be formed by forming the left and right side surfaces 15 and 16 to satisfy the condition of W1 > W2. Here, W1 is the width between the upper ends of the left and right sides, and W2 is the width between the lower ends of the left and right sides.

In addition, as shown in FIG. 43, the undercut portion U is formed such that the left and right side surfaces 15 and 16 are formed such that the width W1 between the upper ends is wider and the width W2 between the lower ends is narrower. Protrusions 15a and 16a are formed at the lower ends of the left and right sides 15 and 16 so that the width W4 between the protrusions 15a and 16a is the width between the upper ends of the left and right sides 15 and 16. It can be comprised so that it may become the same as (W3).

In addition, as shown in FIG. 44, the undercut portion U has protrusions 15b and 16b and protrusions 15b and 16b formed at upper and lower ends thereof. It can comprise by forming in the vertical surface 15c, 16c formed concave between them.

In addition, as shown in FIG. 45, the undercut portion U has protrusions 15d and 16d and protrusions 15d and 16d formed at upper and lower ends thereof. It can comprise by forming in the recessed surface 15e (16e) formed concave between.

Since the articulated low height movable barrier according to the present invention has an undercut portion U at left and right sides of the barrier body 10, the height Hc of the collision point Pc of the wheel 1 of the collision vehicle is wheels. It is located higher than the height Ho of the center O of (1), so that the collision vehicle cannot ride over the barrier body 10.

Therefore, in the conventional mobile barrier, it is possible to prevent a large accident due to the secondary collision caused by the collision vehicle to cross the barrier body and beyond the road boundary to other roads.

In addition, the articulated low-moving barrier type according to the present invention is provided with an undercut portion (U) at the left and right sides, so that the undercut portion of the barrier body (10) is coupled to the crane or excavator by using a forceps to lift both sides with forceps. The slip phenomenon does not occur between U and the tongs. Therefore, it is possible to prevent the safety accident due to the fall of the barrier in transporting tongs, such as crane or excavator.

On the other hand, in the case of conventional temporary barriers or movable barriers (plastic barriers, concrete barriers) because the height is high, in the construction section, for example, in the section such as pedestrian crossing and pedestrian passage in the urban subway construction site, the small car driver's eye height is low But there is a problem that acts as a factor to increase the risk of accidents by disturbing the perception of workers, especially children.

According to the present invention, when the height and width of the barrier body 10 are set to 200 mm to 500 mm, and the length is set to 1000 mm to 4000 mm, when installed in a city subway construction site as a temporary barrier or a movable barrier, a small car driver having a low snow height Road pedestrians and workers, especially children, can be easily recognized, reducing the risk of accidents.

The articulated low height movable barrier according to the present invention can be used as a barrier for a bicycle road by attaching a handrail (not shown) on the upper surface of the barrier body 10.

As described above, when the articulated low height movable barrier according to the present invention is installed as a bicycle road barrier, the height of the barrier body 10 is relatively low, so that the cyclist can rest on the barrier body 10 and rest. May be provided.

In general, a facility such as a temporary barrier is installed at a place where traffic flows meet or separate, especially at a point where the traffic flows, such as a road confluence part and a separation part, and a lane control rod is installed. There is a problem that obscures their view, and in the case of lane-regulated rod there is a problem that leads to an accident by invading the lane because there is no vehicle protection ability.

On the other hand, the articulated low type high movable barrier according to the present invention can be utilized as a lane regulation facility by attaching a lane regulating rod or delinate to the upper part of the barrier body 10, and when installed at a confluence point or a separation point, it obscures the field of view. In addition, since the barrier body 10 itself has a vehicle protection capability, it is possible to prevent an accident due to lane invasion.

As described above, the refractive connection type low height movable barrier according to the present invention can be utilized as various facilities.

On the other hand, in the case of the plastic barrier molded in plastic and used to fill the water or sand therein, there is a difficulty in management, especially if the water or sand is frozen in the winter, the plastic is destroyed when the vehicle crash and loses protection ability There is a problem.

On the other hand, the articulated low-moving barrier type according to the present invention has no management difficulty, and does not freeze even in winter, so that there is no fear of destruction in a vehicle crash.

In the above, the present invention has been described with reference to the illustrated drawings as a preferred embodiment, but the present invention is not limited by the embodiments and drawings presented in the present specification, the present invention within the scope of the technical idea of the present invention.
