Description

Independent functional easy to maintain using joint preventing jaywalking fence and construction method thereof

The present invention relates to a trespassing prohibition fence (center lane separator, etc.), and more particularly, it prevents accidents caused by pedestrians' trespassing and illegal U-turns of vehicles and two-wheeled vehicles, etc. It relates to a self-contained trespassing fence and its construction method, which can be easily and quickly assembled and reused even in curved sections, and is easy to maintain by using a connector that can be easily constructed along the line of a lane even in a curved section.

This section provides background information related to the subject matter of the present application and is not necessarily prior art.

A variety of products are being operated on roadways and sidewalks, such as pedestrian and vehicle safety facilities, such as trespassing facilities (fences), lane dividers, pedestrian protection fences, and guard rails.

The trespassing prohibition facility is similar to the vehicle protection fence installed in the median zone of urban roads, but does not have a vehicle protection function. It is defined as a facility installed to induce the driver's gaze at city Its function is to prevent traffic accidents caused by trespassing and illegal U-turns of vehicles and two-wheeled vehicles.

The shape of the trespassing facility has a shape similar to that of a railing (fence) composed of a pole and a lateral member, and the height of the upper end of the lateral member is 90cm from the road surface as a standard, ensuring visibility into opposite lanes, and preventing pedestrians crossing the road. It must be possible to prevent falling between or under the members, and the trespassing facility is stipulated in the shape of a continuous line of sight guidance by installing it at the same height in the same section.

Specifically, it is stipulated that the material of the trespassing facility should have low deflection during long-term installation, low deformation at room temperature, excellent durability, and easy maintenance, and should have sufficient ductility to prevent impact to the vehicle in the event of a collision.

In addition, as for the color of the trespassing facility, the color of the pillar (post) is based on an achromatic color, and in the case of the attached reflective paper, it is stipulated that yellow is the principle and high-brightness reflective paper must be used.

For example, the trespassing prohibition facility according to the prior art is an independent type in which both sides of the run are fixed to both posts, respectively, blocking between the posts, the center of the run is fixed to the post, and the left and right sides are fixed to the neighboring posts. classified as connected.

The stand-alone trespassing facility has the advantage that only the pole and rib assembly where the vehicle collided with the vehicle behaves and the rest of the pole and traverse assemblies do not move, but only one strut and traverse assembly is fixed only to the ground. Since it is not connected to the assembly, severe shaking caused by strong winds, etc. may occur, which may cause a collision with a moving vehicle, and there are disadvantages in that pedestrians may cross by forcibly pushing one pole and crossbar assembly.

On the other hand, the connected type can effectively prevent pedestrians' trespassing, but compared to the free-standing type, all the runways behave together because the adjacent runways are connected to each other, that is, from the point where the vehicle collided to the farthest poles and runways affected. There are disadvantages.

Registered Patent No. 10-1757260, which was patented by the applicant of the present invention as a patent document to solve this problem, is a holding body that elastically behaves by external force, is formed in the bottom of the holding body with a larger cross-sectional area than the holding body, It consists of a base fixed to, and is installed at a predetermined distance from each other along the road, and two or more poles; a horizontal bar having at least one stage in each of the posts, and blocking the space between the posts by having a central part connected to the posts so that both sides in the longitudinal direction protrude from the posts; Connecting the adjacent ends of the crossbars respectively installed on the poles, and connecting the crossbars and the poles connected to each other so that they elastically behave independently of the neighboring poles and poles, wherein the connector includes a support part and a fixing part on both sides in the longitudinal direction Formed or composed of only fixing parts without a support part and made of an elastic connection part that is elastically deformed by an external force so that the cross bars are pushed by an external force, the support part is inserted to be movable in the cross bars, and the fixing part is elastically fixed with a locking jaw The piece is configured so that the elastic fixing piece is fitted into the connector fixing holes formed on the one side and the other side, respectively, and the locking jaw is hooked and fixed. It prevents damage to the vehicle by being pushed by the falling force, and on the other hand, since the cross bars are connected to each other and do not cause shaking due to strong winds, it is possible to prevent damage to the vehicle due to the shaking of the cross bars, but there are the following problems.

First, as shown in (A) of Figure 1, the connector (1) has a fixing part (1a) on one side fixed to the crossbar (2) on one side and the insertion part (1b) on the opposite side to the crosspiece (3) on the opposite side. As a structure that is movable (separated) inserted, the purpose can be achieved by connecting the adjacent crossbars 2 and 3 with the connector 1 at the time of initial construction, but the insertion of the connector 1 due to a vehicle collision The part (1a) can be separated from the opposite side (3), and when the insertion part (1a) is detached in this way, the purpose cannot be achieved because the cross members (2, 3) cannot be connected. It must be reused by inserting it into the crossbar (3) of the crossbar (2,3) and the structural problem of the non-movable structure and the connector (1) (the structure in which the fixing part (1a) and the insertion part (1b) are integrated) As a result, it is not possible to insert the separated insertion part 1b of the connector 1 into the opposite side crossbar 3, so that the insertion part 1b is reused in a detached state.

In such a state, since the rungs (2,3) seem to be connected, they are reused without the manager's instructions for repair. There is a problem in that the beating phenomenon occurs and it is not possible to prevent pedestrians from crossing while forcibly bending, but there is a problem in that they are eventually damaged due to this reason. will also fall

In addition, it cannot be used in a curved section because it is possible only to connect the crossbars in a straight line due to the structure of the connector and the connection structure.

In addition, in a state in which the end of the crosspiece is overlapped with the wing part protruding to the pole, the hook penetrates from the front end of the wing part to the rear end of the opposite side, and there is also a problem in that the wing part of the pole is torn.

Registered Patent No. 10-1757260

The present invention is to solve the problems as described above, and by connecting the neighboring rungs fixed to the holding assembly, it is possible to prevent pedestrians from crossing the rungs without permission and the ends of the runways from being shaken by strong winds, and also the collision of a vehicle, etc. In case the rungs are separated due to this, the runways are connected and constructed simply and easily and without the use of separate equipment. The purpose of this is to provide an independent functional trespassing prohibition fence that is easy to maintain and maintain using a connector that moves independently without doing so and its construction method.

And, another object of the present invention is to connect the ends of the adjacent rungs to enable safe reuse while connecting the neighboring rungs with a curve that fits the linearity of the lane.

Another object of the present invention is to prevent the wing formed on the post from being torn while firmly fixing the post and the crossbar.

The independent functional trespassing prohibition fence, which is easy to maintain using the connector according to the present invention, is a post whose bottom is fixed to the ground, and a multi-stage crossbar that is fixed through a hook to a wing formed protruding in multiple stages to the periphery of the post. And two or more posts and crossbar assemblies that are made of and are installed at a predetermined distance from each other; It includes a connector connecting the adjacent ends of the cross bars formed in the two or more posts and the cross bars assembly, the connector is inserted and fixed to the adjacent cross bars, respectively, the first connected to enable coupling and separation using the unevenness, Consisting of two connecting blocks, the first and second connecting blocks each have a cross-bar fixing part inserted and fixed to the cross-bar, respectively, protruding from the cross-bar fixing part, stacked up and down with each other and fitted with a connecting protrusion and a protrusion having a connecting groove It characterized in that it includes a type connecting piece and a grooved connecting piece, and a guide rail formed from the edge of the grooved connecting piece to the connecting groove to guide the insertion and movement of the connecting protrusion.

According to the independent functional trespassing prohibition fence that is easy to maintain using the connector according to the present invention and its construction method, the connector is inserted into the adjacent crossbar, respectively, and is composed of two connecting blocks that are coupled to each other, It is very easy to assemble by connecting the protruding connecting blocks, for example, by connecting the crossbars formed in the double-armed beam type post and the crossbar assembly. Because it is possible to connect the crosswalks simply and quickly without using Edo equipment, it can be reused even after a vehicle collision. Even in strong winds, it can prevent the cross-section from collided with a vehicle, thereby protecting both pedestrians and vehicles.

In particular, the present invention prevents pedestrians' trespassing in all parts by connecting the crossbars to each other, while the crossbars are separated from each other through the connector through the connector to enable an independent function to move independently without restraint. It has the effect of reducing damage.

In addition, by configuring the two connecting blocks to adjust the angle, they can be installed anywhere, including straight sections and curved sections of various angles. There is an effect of improving, and in particular, since the configuration of the angle adjustment is possible only by forming the connecting protrusion and the connecting groove in a circular shape using the connecting structure of the connecting block, there is an effect that can be manufactured simply without change.

In addition, in the connection of the post and the crossbar, the hook is separated from the structure that penetrates the entire wing and the crossbar and divided into the front and rear hooks that penetrate only the thickness of the wing and the crossbar. And it has the effect of reducing the breakage of the cross section.

Through the above effects, there is an effect that the national budget can be saved by reducing the cost due to frequent maintenance of the trespassing fence.

In the following description of the present invention, if it is determined that a detailed description of a related well-known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the terms described below are terms defined in consideration of functions in the present invention, which may vary according to intentions or customs of users and operators. Therefore, the definition should be made based on the content throughout this specification.

As shown in FIGS. 2 and 3, the independent functional trespassing prohibition fence 100, which is easy to maintain using the connector according to the present invention, is, for example, a post 20 and a multi-stage crossbar 30. A post and cross bar assembly 10 assembled in a bi-arm type, and a connector 40 connecting the adjacent cross bars 30 of the adjacent post and cross bars assembly 10, the connector 40 is the adjacent cross bar It is composed of first and second connection blocks 50 and 60 that are coupled and separated from each other so that they can be connected even in a separate state.

The post and cross bar assembly 10 is in the form of a double-armed beam in which the cross bar 30 protrudes to the left and right sides with respect to the post 20 as a reference, and preferably the cross bar 30 is coupled to both sides of the post 10, respectively. And, as another example, a form in which one crossbar 30 passes through the post 20 is also possible.

The post 20 is formed to protrude from the left and right sides to the base 22 and the post body 21 that are formed at the bottom of the post body 21 and the post body 21 and are fixed to the ground, and the crossbar 30 is connected and fixed. It is composed of a wing portion 23 that is, for example, made of a synthetic resin injection.

The holding body 21 is, for example, made of a hollow circular or rectangular or other shape with a hollow inside, and the base 22 is fixed to the ground with an anchor or the like while having a larger area than the holding body 21, and the wing The part 23 is formed to protrude from the periphery of the post body 21 to provide a support base for firmly fixing the crossbar 30 and is fixed with a hook 24 after the crossbar 30 is inserted therein.

The wing part 23 may be of an integral type manufactured together with the post body 21 or an assembly type in which a hole passing through the left and right sides is formed in the post body 21 and then inserted and fixed in the hole.

The wing portion 23 is to change depending on the outer shape of the crossbar 30, preferably formed in two or more stages in three stages so that the three-stage crossbar 30 is installed.

The crossbar 30 is fixed to the wing part 23 through the fastening of the hook 24 after the end is inserted into the wing part 23, compared to the conventional one long hook penetrating from the front to the back of the wing part. , In the present invention, each hook 24 is fastened to the front and rear of the wing 23 so that the ends of the wing 23 and the crossbar 30 are not torn apart during the impact test. That is, the hook 24 does not penetrate the inner space of the crossbar 30 but penetrates only the thickness of the wing portion 23 and the crossbar 30 to fix them.

The specific structure of such a hook 24 is a hook rod 24a penetrating through a hook hole formed to coincide with the wing portion 23 and the crossbar 30, and a hook rod 24a at the inner end of the hook rod 24a. ) is formed with a larger outer diameter than the chin 24b caught on the inner surface of the crossbar 30, and a hook head 24c formed larger than the hook hole at the outer end of the hook rod 24a, and a hook Two or more, preferably four, of the rod 24a and the jaw 24b are retracted while the jaw 24b passes through the hook hole and open elastically after the jaw 24b passes the hook hole. It is formed to be arranged in a circle along the circumferential direction.

The jaw 24b has an inclined (mountain)-shaped outer surface for smooth insertion and elastic behavior.

The hook 24 may be made of nylon to prevent scattering.

One or more of the hook holes formed in the wing portion 23 and the crossbar 30 is preferably a long hole, and the horizontal movement of the crosspiece 30 is possible through the long hole, so that the post 20 and the crossbar 30 are assembled. It can facilitate the assembly and also help the assembly of the connector (40).

The crossbar 30 protrudes to the side of the pole 20 and blocks pedestrians from crossing without permission through between the poles 20, and one side is inserted into the wing part 23 of the pole 20 and the hook 24 fixed by fastening of

The crossbar 30 is preferably composed of a square-shaped forming tube (the upper and lower portions are larger than the central portion) in order to increase the bending rigidity.

Two or more posts and cross bars assembly 10 configured in this way are installed along the lane, and at this time, the cross bars 30 of the adjacent posts and cross bars assembly 10 are connected to each other through the connector 40 .

The connector 40 functions as follows.

1. Crossbar 30 Connection: Connecting the free ends of the adjacent crossbars 30, that is, the crossbars 30 having one side fixed with a hook 24 to each post 20.

2. Easy reuse: Reuse of the trespassing prohibition fence by easily connecting the cross bars 30 in a state in which the adjacent cross bars 30 are disconnected due to a collision of vehicles, that is, in a state in which the cross bars 30 are separated.

3. Collision energy absorption: When a vehicle, etc. collides with the cross section 30, the adjacent cross section 30 is pushed back to absorb the collision energy.

4. Curved section installation: Not only the adjacent rungs 30 are installed in a line (a straight section of the lane), but also the neighboring rungs 30 are installed at the same angle as the curved section of the lane.

As shown in FIG. 6, the connector 40 for performing the above function is inserted and fixed to the adjacent cross bars 30, respectively, and the coupling and separation are made of first and second connecting blocks 50 and 60.

The first and second connection blocks 50 and 60 include parts inserted into the ends of the adjacent cross bars 30, respectively, and parts that are coupled and separated from each other (cross connection function), and for assembly in parts that are coupled and separated from each other. A part is included (easy reuse function), a guide part for separation is included (collision energy absorption function), and a part for coupling is formed in a circle (curve section installation function), and a preferred configuration will be described below.

The first connecting block 50 is a first protrusion-type connecting piece 52 as a first cross bar fixing part 51 inserted and fixed to one side of the cross bar, and two first connecting pieces protruding from the first cross bar fixing part 51 . and the first groove-shaped connecting piece 53, as any one of the connecting protrusions 54 formed on the upper surface of the upper first protruding connecting piece 52 based on the drawing, and the lower first groove-shaped connecting piece 53 formed on the upper surface It is composed of a connection groove 55 and a guide rail 56 formed from the connection groove 55 to the edge.

The second connection block 60 has the same structure as the first connection block 50 and is coupled to each other by turning upside down, that is, the second crossbar fixing part 61 and the second protruding connection piece 62 as the second connection piece. and the second groove-type connecting piece 63, the connecting protrusion 64 formed on the lower surface of the second protruding connecting piece 62 on the lower side, the connecting groove 65 formed on the lower surface of the upper second groove-type connecting piece 63, It is composed of a guide rail 66 formed from the connecting groove 65 to the edge. Therefore, the manufacturability is also very excellent by using two connecting blocks manufactured by one type of mold instead of using each mold.

According to the above structure, since all of the first and second connecting blocks 50 and 60 have the connecting protrusions 54 and 64 and the connecting grooves 55 and 65, only one connecting block has a connecting protrusion and the other connecting blocks have connecting protrusions. The connection strength can be increased compared to having only a connection groove.

The first and second crossbar fixing portions 51 and 61 may be fixed by force press-fitting into the crosspiece 30, respectively, or may be fixed by insertion and fastening of a fastener (hook).

The guide rails 56 and 66 are formed from the edges of the first and second grooved connecting pieces 53 and 63 to the inner connecting grooves 55 and 65 so that the connecting protrusions 54 and 64 are connected to the first and second grooved connecting pieces 53 . , 63) provides a path to be inserted into the connecting grooves 55 and 65, and also provides a path through which the connecting protrusions 54 and 64 are separated.

Two or more guide rails 56 and 66 are radially formed based on the connection grooves 55 and 65 to ensure easy assembly.

The connecting protrusions 54 and 64, the connecting grooves 55 and 65, and the guide rails 56 and 66 may have the same shape for an organic relationship.

However, for the installation of the curved section, the connecting protrusions 54 and 64, the connecting grooves 55 and 65 and the guide rails 56 and 66 are hemispherical (semi-circular) so that the first and second connecting blocks 50 and 60 are angularly adjusted. ) is formed from

The first and second connection blocks 50 and 60 include the first and second protrusion-type connecting pieces 52 and 62 and the first and second groove-type connecting pieces 53 and 63 and with them so as to maintain a solid coupling relationship even when the angle is adjusted. The inner surfaces of the opposite first and second horizontal band fixing parts 51 and 61 are formed in a curved shape.

In addition, angle adjustment protrusions 57 and 67 and angle adjustment grooves 58 and 68 are included so that when the angle of the first and second connection blocks 50 and 60 is adjusted, the angle adjustment feeling can be felt.

The angle adjustment protrusions 57 and 67 and the angle adjustment grooves 58 and 68 are formed to face each other on the first and second protrusion-type connecting pieces 52 and 62 and the first and second groove-type connecting pieces 53 and 63, so that the coupling and The angle adjustment operation of the first and second connection blocks 50 and 60 can be felt through the tactile sense felt through separation.

A plurality of the angle adjusting protrusions 57 and 67 and the angle adjusting grooves 58 and 68 may all be radially formed on the basis of the connecting protrusions 54 and 64 and the connecting grooves 55 and 65, of course, one of the angle adjustment protrusions (57, 67) and a plurality of angle adjustment grooves (58, 68) or vice versa.

Since the angle adjustment protrusions 57 and 67 and the plurality of angle adjustment grooves 58 and 68 only give a feeling of angle adjustment, a lower height than the connecting protrusions 54 and 64 is preferable.

The construction (reassembly of the detached connector) method of the independent functional trespassing prohibition fence that is easy to maintain using the connector according to the present invention is as follows.
1. Step 1.
Install the post and crossbar assemblies 10 along the lane.
2. Step 2.
The first and second connecting blocks 50 and 60 of the connector are respectively inserted into the cross bars 30 adjacent to the posts and the cross bars assembly 10, and the connecting protrusions and connecting grooves of the first and second connecting blocks 50 and 60 are formed. The cross bars 30 are connected by coupling the first and second connecting blocks 50 and 60 by fitting, and the specific process is as follows.

The step of installing the post and crossbar assembly is a step of placing the base 22 of the post 20 on the road surface and installing it as an anchor.

The process of connecting the adjacent crossbars 30 (connecting the first and second connecting blocks 50 and 60 of the connector 40) is as follows.

As shown in (A) of Figure 7, the first and second connection blocks 50 and 60 are in a state in which the first and second crossbar fixing parts 51 and 61 are fixed in the crossbar 30 and are not connected to each other, respectively. , for example, may be said to be in a state of being separated from each other due to a collision of a vehicle.

In order to connect the cross bars 30, for example, the connecting protrusion 54 of the first connector 50 is aligned with the inlet (opposite of the connecting groove 65) of the guide rail 66 of the second connector 60 and , when the first and second connecting blocks 50 and 60 are pushed in a direction to be gathered together, the connecting protrusion 54 moves along the guide rail 66 as shown in FIG. 7 (B) and the connecting groove 65 inserted inside In this case, the first and second connection blocks 50 and 60 are stacked up and down and combined.

8 is a plan view showing an example of installation in a straight section, and the first and second connecting blocks 50 and 60 of the connector 40 maintain a state in which they are arranged in a line to install the cross bars 30 in a straight line.

On the other hand, as shown in FIG. 9 , in the case of construction in a curved section, as described above, in a state in which the connecting protrusions 54 and 64 of the first and second connecting blocks 50 and 60 are inserted into the connecting grooves 55 and 65 in a coupled state. By turning the first or second connecting blocks 50 and 60 according to the angle of the lane, the adjacent crossbars 30 are installed in a form having a predetermined angle rather than a straight line. At this time, the angle adjustment protrusions 57 and 67 can feel the manipulation feeling while riding between the angle adjustment grooves 58 and 68 - the angle adjustment grooves 58 and 68. When the angle adjustment protrusions 57 and 67 are inserted into the angle adjustment grooves 58 and 68, the first and second connection blocks 50 and 60 maintain the angle adjustment state.

The stand-alone functional trespassing prohibition fence 100, which is easy to maintain using the connector according to the present invention, is the adjacent crossbar 30 of the post and crossbar assemblies 10 as shown in FIG. 2 in usual times, the connector 40 It is connected through, that is, since one side of the crossbar 30 is supported on the post 20 and the other side is supported on the adjacent crossbar 30 through the connector 40, the pedestrian pushes the crossbar 30 and the crossbar ( 30) can be prevented from crossing without permission, and the crossbars 30 collide with a driving vehicle while shaking with a strong wind and do not cause a phenomenon of damaging the vehicle.

In addition, when the vehicle collides, the connecting protrusions 54 and 64 of the first and second connecting blocks 50 and 60 absorb the collision energy applied from the vehicle while moving along the guide rails 56 and 66 as a path, It does not apply a secondary impact to the device and does not cause secondary damage.

In addition, when the first and second connecting blocks 50 and 60 are separated, that is, the connecting protrusions 54 and 64 are separated from the connecting grooves 55 and 65 due to the large collision energy applied from the vehicle, as described above, the second The connecting protrusions 54 and 64 are inserted into the connecting grooves 55 and 65 through the guide rails 56 and 66 by slightly bending the opposite ends of the cross bars 30 to which the first and second connecting blocks 50 and 60 are coupled. Because it can be reassembled with a simple and easy operation without removing the fence, it can be reused for a long time.
