Description

Installation structure of traffic sign

The present invention relates to the installation structure of the traffic sign (traffic sign) is installed on the road to promote the safe operation of the vehicle, more specifically, it is easy to support the sign (sign board) in which various matters necessary for the operation of the road marked Although it can be installed in such a way that it is possible to improve the durability against physical forces from the outside, such as strong winds, and more particularly relates to a traffic sign installation structure that can be easily recovered at a low cost while minimizing the damage of the signage caused by the vehicle crash.

In general, the road edge is notified to drivers and pedestrians of various dangers that may occur on the road to ensure safe and smooth road traffic, and to maintain road structure. Traffic signs are posted to inform you.

Such traffic signs are produced and installed as prescribed by law, and the contents to be conveyed are represented by graphic symbols such as letters, numbers, arrows, or a combination thereof. In addition, according to the content to be delivered, it is classified into a caution sign, a regulatory sign, an indication sign and a guide sign.

Therefore, traffic signs should be easy to recognize at relatively long distances and should be able to be read at night. The reflective signs are made by attaching reflectors to the surface of signs, so that the installation status cannot be changed by physical external forces such as strong winds. It is firmly fixed to the ground through the shore.

On the other hand, since the traffic sign is installed on the road, damage caused by a crashing vehicle is frequently generated, and in this case, it causes a great obstacle to the safe operation of other vehicles until recovery.

In particular, as shown in FIG. 1, in the case of the direction indicator S, which is called a so-called chevron cover installed on the curved section of the road R, the structural characteristics of the road R not only have a high risk of vehicle collision but also a frequency of occurrence. Is also very high. In addition, when the direction indicator S of the curved section is damaged due to a vehicle collision, it is difficult for the driver to recognize the curved section, and the accidents increase greatly. Especially, when driving at night, the classification of the curved section becomes more difficult. The risk is significantly increased.

Therefore, in order for the traffic sign to fully function, it is desirable that the traffic signs not be easily changed or damaged by strong winds or vehicle collisions, and have an installation structure that can be quickly restored in case of damage.

2 and 3 show an example of a conventional traffic sign installation structure, which is the most common installation structure of a direction indicator installed on a curved road. This is to fix the lower end of the support (1) to the base concrete (2) on the road side, and a plurality of channel guide rails (4) to the back of the sign (3) made of metal bonded to each guide Insert the head of the bolt 6 into the rail 4, and then fasten the U-band (5) to the support (1) and fasten the flanges (5a) at both ends to the bolt (6) with the nut (7). I install it by doing it.

The conventional traffic sign device having such a configuration can also be found, for example, in Korean Utility Model Registration No. 0217061.

By the way, such a conventional traffic sign mounting structure is to assemble a bolt (6) to each guide rail (4) provided on the back of the sign (3) and then to hang a plurality of U bands (5) on the support (1) Since the nut 7 must be fastened to the bolt 6, the installation work is quite complicated.

Particularly, since the sign 3 is made of a thin steel plate, when the strength is weak and an external force such as a vehicle collision is applied, the sign 3 is easily deformed as shown by a virtual line in FIG. This phenomenon is more noticeable on curved road direction indicators (S) using relatively small pipes as props, and speed limit signs (not shown) on provincial roads or national roads.

In this case, both the sign 3 or the sign 3 and the support 1 must be replaced, and the recovery time is long, so that not only the risk of accidents is high but also a considerable cost of recovery is required.

In addition, since each component is made of iron and is coated, the coating is peeled off due to weather, etc., if it elapses for a long time, oxidation corrosion occurs and rust is rusted, as well as the fastening guide rail 4 and the bolt 6 ) Are exposed to the outside as it hurts the aesthetics of the road.

On the other hand, Korean Utility Model Publication No. 0298089 discloses a configuration in which the sign is injection molded into plastic to form a holding seat groove on the back, and then the U-band is bolted to the sign and the support through the non-slip pad. It is.

However, this technology does not cause signs to rotate or corrode due to strong winds.However, the strong clamping force due to the anti-skid pad is more likely to break the sign when the vehicle crashes, and the fastening band is exposed to reduce the road aesthetics. do. In addition, when the landlord is bent, there is a problem of the complexity of having to replace both the sign and the landlord, the risk of accidents caused by delayed recovery time, and excessive recovery cost.

The present invention has been made to solve the above-mentioned conventional problems, to provide a traffic sign installation structure that can prevent the sign is broken by a vehicle crash while preventing the change of the setting position of the sign due to strong winds. The purpose is.

Another object of the present invention is to provide a traffic sign installation structure that can easily install a sign on a support, and can achieve a beautiful appearance by fundamentally preventing oxidation corrosion while minimizing the exposure of the fastening portion with the support. .

Another object of the present invention is to provide a traffic sign installation structure that can reduce the risk of accidents and the recovery cost by rapid recovery by minimizing the damage to the signs and props caused by a vehicle crash.

In order to achieve the above objects, the first embodiment of the traffic sign installation structure according to the present invention includes a lower end portion of which a lower end is fixed to a road side by a foundation concrete, and a lower end portion of which is inserted into the lower end portion by a plurality of screws. A prop consisting of a fixed upper column; A synthetic resin sign having a post pocket for inserting the upper end of the upper brace perpendicular to the back, protruding the reinforcing beads at the front edge, and recording a predetermined mark on the inner region of the reinforcing beads; And a plurality of bolts for fastening through the upper end of the holding pocket and the upper post of the sign.

In addition, a second embodiment of the traffic sign installation structure according to the present invention, the hinge bracket (hinge bracket) is installed on the foundation concrete embedded in the road; A support having a lower end supported by a hinge bracket to be lever-movable; A damper that is connected to both ends of the foundation concrete and the support to maintain the support vertically, and to return the support which has fallen due to a vehicle collision to its initial state; A synthetic resin signage having a holding pocket vertically inserted into a rear surface of the upper portion of the holding portion, and having a predetermined label recorded on the front surface thereof; It characterized in that it comprises a; a plurality of screws for fixing the holding post of the sign to the upper end of the post inserted therein.

A third embodiment of the traffic sign installation structure according to the present invention, the lower end is fixed to the road side by the foundation concrete, the upper end having a predetermined length of male thread; Signs made of synthetic resin having a holding pocket perpendicular to the back, inserting the upper end of the support, the predetermined label is recorded on the front; And a screw socket which is insert-molded in the inner circumference of the support pocket of the sign and screwed with the male screw of the support.

Accordingly, in the present invention, the lower column is fixed to the base concrete during installation, and the upper part of the upper pillar is joined to the holding pocket of the sign and fastened with bolts, and then the lower end is inserted into the lower column to fix the screw. It can be installed very easily with respect to the support, as well as the fastening portion of the sign and the support is not exposed to the outside can realize a beautiful appearance.

In particular, as the screw is dislodged by the external force applied to the sign during the vehicle crash, the upper column and the sign are rotated with respect to the lower column, thereby minimizing breakage, thereby enabling reuse as well as rapid recovery.

In addition, the damage is suppressed as much as possible by the fall of the props without bending when the vehicle is crashed. When the external force is removed, the props are returned to their initial state by the damper, so the driving safety of the vehicle and the extension of the life of the traffic sign are exerted. Done.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

4 to 6, the first embodiment of the traffic sign installation structure according to the present invention is characterized by a support 10 installed vertically on the road side and a plurality of bolts 16 at the upper end of the support 10. It is concluded is composed of a sign 20 to display the predetermined delivery information about the road traffic.

The strut 10 is composed of lower and upper column 12, 13 whose corresponding ends are coupled to each other and fixed by screws 30. The lower column 12 is fixed to the road by inserting the lower end into the foundation concrete 40 embedded in the ground, and for example, two screw holes 11 are vertically fixed to fasten the screw 30 to the outer periphery of the upper part. The upper column 13 is integrally fastened with the sign 20 by a plurality of bolts 16 through which the upper end is fitted into the holding pocket 21 of the sign 20 described later, and penetrates them. The lower end outer periphery fitted to the upper end of the lower support 12 has up and down fastening holes 14 to which the screw 30 is fastened so as to correspond to the screw holes 11 of the lower support 12. For example, it is made of a steel pipe of a circular cross-section, and at the upper end of the upper column 13, at least two through holes 15 for fastening the sign 20 with bolts 16 are formed at intervals up and down.

Sign 20 is made of high-strength synthetic resin, preferably FRP resin. In the middle of the back surface of the sign 20, a substantially cylindrical post pocket 21 which completely inserts the upper end of the post 10 is formed to protrude vertically long, and the reinforcement bead 23 preferably protrudes near the front edge thereof. Is formed.

The reinforcement bead 23 increases the strength of the sign 20, as well as the circumference of the reflector 24 and the delivery matter mark 25 attached to the front of the sign 20 as shown in FIG. By wrapping the reflective paper 24, etc., to protect it from falling easily.

The holding pocket 21 is integrally formed at the time of forming the sign 20, the upper end of which is caught by the bolt 16 by avoiding the exposure of the support 10 and allowing the sign 20 to span the support 10. Only the bottom is opened to allow insertion of the strut 10 while being closed to reduce the load.

That is, when the upper end of the holding pocket 21 is opened, the sign 20 is supported by the support 10 only by the bolt 16, so that a stronger tightening force is maintained in order to maintain a setting position against external forces such as strong winds. Although required, as shown, when the upper end of the holding pocket 21 is blocked, since the sign 20 is supported by the support 10 so as to be supported by the support 10, a stable fastening state may be achieved even if the fastening force is not so great. It can be maintained.

On the main surface of the holding pocket 21, two through holes 22 are formed to be spaced up and down so as to correspond to the through holes 11 formed in the upper column 13.

Accordingly, the upper end of the upper support 13 is inserted into the holding pocket 21 of the sign 20, and both are fastened to the bolt 16 through the through holes 15 and 22, and then the lower support 12 and the upper part are fastened. Fix the support (13) with a screw (30), so that the front of the sign 20 to the driver's gaze of the driving driver to fix the lower column 10 to the road side by the foundation concrete 40, traffic signs (S) can be installed very easily.

In addition, the sign 20 is formed of a high-strength synthetic resin and is strongly fastened to the upper column 10 with a plurality of bolts 16 through a holding pocket 21 integrally provided on the rear surface thereof, and the upper column 13 is Since the screw 30 is fixed to the lower column 12, the change of the setting position due to the strong wind is effectively prevented. In particular, as shown in FIG. 7, when the vehicle collides with the sign 20 and a momentary large impact force is applied, the bolt 16 is fastened to the fastening portion of the upper support 13 and the sign 20 which are fastened. Compared to the sign 20, the upper column 13 rotates with respect to the lower column 12 while the screw 30 fixing the lower and upper column 12 and 13 having a relatively small fastening force is released. As shown in the drawing, the upper column 13 is rotated together to prevent breakage.

In this case, an accident caused by the damaged traffic sign S can be quickly recovered by damaging the traffic sign S only by a very simple operation of resetting the upper land 13 to the lower land 12 with a new screw 30. The possibility of occurrence can be significantly reduced.

Furthermore, since the sign 20 of the present invention accommodates the support pocket 21 so as to completely cover the upper end of the support 10, there is no fastening portion other than the bolt 15, so the appearance is not only beautiful but also oxidative corrosion is fundamental. As it does not occur, the life is greatly extended.

8 to 10B show a second embodiment of the traffic sign installation structure according to the present invention.

The second embodiment is a post 10, a sign 20 which is fixed to the upper end of the post 10 by a screw 30 to display a predetermined transmission matter regarding road traffic, and the post 10 by road. The hinge bracket 50 supporting the lever movement on the base concrete 40 embedded in the street, and the damper for maintaining the support 10 vertically and restoring the support 10 that has fallen due to a vehicle collision to the initial state. In other words, the hinge bracket 50 is fixed to one side of the foundation concrete 40 and the lower end of the pillar 10 is fastened to the hinge bolt 51 by fixing the hinge bracket 50 to one side of the foundation concrete 40. The support 10 is held vertically by supporting the lever 10 so as to be capable of lever movement, and supporting one side of the support 10 to the foundation concrete 40 by the damper 60. The support 10 is, for example, It is made of steel pipe of circular section, and on the upper part to fix the sign 20 with screws 30 At least two screw holes 11 are formed at intervals up and down. The cover plate 20 is formed of high strength synthetic resin, such as FRP, in the same manner as in the first embodiment, and has an upper end portion of the support 10 in the middle of the back surface thereof. The approximately cylindrical holding pockets 21 for completely inserting the protrusions are formed to extend vertically. And preferably near the front edge of the sign 20, while increasing the strength of the sign 20 and wrapped around the reflective paper 24 and the delivery matters 25 attached to the front of the sign 20 Reinforcement beads 23 are formed to protrude to protect the reflective paper 24 and the like from falling easily. The holding pocket 21 is integrally formed at the time of forming the sign 20, and an upper end thereof is exposed to the support 10. At the same time, the sign 20 is closed to allow the insertion of the support 10 only at the lower end, so as to reduce the load on the screw 30 by allowing the sign 20 to span the support 10. When the upper end of the 21 is opened, the sign 20 is supported by the support 10 only by the screw 30, so that a strong fastening force is required to maintain the setting position against external force such as a strong wind. 10) Fastening path stably in strong wind If the top of the holding pocket 21 is blocked, as shown, the sign 20 is spanned over the top of the support 10 so that it is supported by the support 10 and the screw 30 is merely a sign 20. Since it is necessary to prevent rotation by strong wind, etc., while maintaining the setting position of), it is possible to maintain a stable fastening state even with the screw 30 only. Two fastening holes 21a are formed at intervals up and down so as to correspond to the screw holes 11 formed therein.

The hinge bracket 50 is formed in an approximately U-shape, and is disposed to face in a direction in which the vehicle that is being driven may bump into and is fixed to the foundation concrete 40 by an anchor bolt 41.

The damper 60 is located on the side of the prop 10 falling down due to a vehicle collision, and is installed to be inclined at an appropriate angle between the outer periphery of the lower end of the support 10 and the base concrete 40. The damper 60 is accommodated in, for example, a cylinder 61, a piston rod 62 slidably assembled to the cylinder 61, and a cylinder 61 to elastically bias the piston rod 62 outward. Compression coil springs 63 for elastic bias.

The cylinder 61 has a fixing plate 64 at the bottom, and is fixed to the foundation concrete 40 with anchor bolts 42. The piston rod 62 has an upper end at the outer periphery of the support 10 through the bracket 65. The hinge is connected.

This second embodiment effectively prevents damage to the signage 20 as well as the support 10 by falling down the support 10 as shown in FIG. 10B during a vehicle crash, and when the external force is removed, the damper 60. The strut 10 is returned to the initial position by the restoring force of.

That is, when the vehicle collides with the sign 20 or the support 10, the support 10 is tilted backward by the impact force at this time, pushing the piston rod 62 of the damper 60, and thus the compression coil spring. The compression deformation of the 63 causes the props 10 to fall and minimizes the damage caused by the collision. When the external force is removed in this state, the piston rod 62 is moved back outward due to the restoration elasticity of the compression coil spring 63. By being pushed out, the support 10 is returned to the initial position.

In particular, since the props 10 themselves fall when the vehicle crashes, damage of the signs 20 is hardly generated, and even in severe cases, the screws 30 for fastening the signs 10 and the signs 20 are severe as shown in FIG. 10A. It is detached or rotated only slightly around the fastening hole 21a of the holding pocket 21, so that the damage of the sign 20 is minimized, so that it can be quickly recovered at low cost. If it is possible to recover the damaged traffic sign (S) quickly by only a very simple operation to re-establish the sign 20 to the support 10 with a new screw 30, the fastening hole 21a of the support pocket 21 If the surrounding is damaged, it can be repaired and fixed by drilling a hole in another location, so that it can also be recovered relatively quickly, significantly reducing the risk of accidents caused by damaged traffic signs (S). 20) of high strength It is formed of a resin resin and fixed to the support 10 with a plurality of screws 30 through the support pocket 21 integrally provided on the back thereof, and thus the change of the setting position due to the strong wind is effectively prevented, and the sign 20 Since the holding pocket 21 accommodates the upper end of the support 10 completely, there is no fastening portion other than the small screw 30, so the appearance is not only beautiful but also does not occur oxidative corrosion. Is extended.

Here, the damper 60 has been described as a spring type, but this is merely for the purpose of illustration, the present invention is not limited to this, and return to the initial state when the fall to the vehicle crash while maintaining the vertical column 10, such as hydraulic or pneumatic Any form that can be made is acceptable.

11 and 12 show a third embodiment of the traffic sign installation structure according to the present invention.

First, in the case of FIG. 11, in the first embodiment described above, instead of fastening the upper end portions of the support post holder 21 and the support post 10 with bolts 16, the support pocket provided on the back of the sign 20 is provided. A screw socket 26 is inserted in the inner circumference of the 21 to insert it in the molding of the sign 20 so as to be integrally formed with the holding pocket 21, and a male screw coupled to the screw socket 26 at the upper end of the support 10. It is a structure which is equipped with 17 and attaches the sign 20 to the support | pillar 10 by screwing.

In this case, the teflon tape or the like may be wound around the male screw 17 of the support 10 as necessary, and then may be coupled to the screw socket 26. When the vehicle collides, the sign 20 is rotated on the support 10 to prevent damage.

In the case of such a configuration, the fastening portion of the sign 20 is not exposed to the outside at the same time as having the same effect as the above-described embodiments, thereby achieving a very beautiful appearance.

On the other hand, in the case of Figure 12, in the above-described first embodiment, the upper periphery of the upper end of the lower column 12 fixed to the base concrete 40, and fastening with a bolt 16 to the holding pocket 21 of the sign 20 The upper and lower pillars 13 are formed by forming screws 12a and 13a on the outer periphery of the lower end of the upper column 13, respectively, and screwing them to both ends of the connecting socket 18 having the screws 18a on the inner circumference. ) 12 is integrally connected.

Even in this case, if necessary, Teflon tape or the like may be wound around the screws 12a and 13a of each support 12 and 13, and then coupled to the connecting socket 18. If the vehicle is collided but the vehicle is collided, the sign 20 is rotated relative to the support 10 to prevent damage.

As described above, according to the traffic sign installation structure according to the present invention, when the traffic sign is installed, the lower column is fixed to the foundation concrete, and the upper and lower holding posts of the signs are coupled to the upper pole, and then fastened with bolts. Since the props can be fixed with screws, the signs can be installed on the props very easily.

In particular, as the screw is dislodged by the external force applied to the sign during the vehicle crash, the upper column and the sign are rotated about the lower column, thereby minimizing damage and thus enabling reuse as well as rapid recovery.

In addition, the damage is suppressed as much as possible by the fall of the props without bending when the vehicle crashes, and when the external force is removed, the props are returned to their initial state by the damper, for example, the direction indicators or road signs installed on the curved section of the road. Especially suitable for speed limit signs.

In addition, since the signage pocket of the sign is completely enclosed in the upper part of the support, the exposure of the sign and the signage of the support is minimized to realize a beautiful appearance, and the sign is composed of a synthetic resin, which prevents oxidative corrosion. Greatly extended.

Therefore, the present invention is a useful invention having an excellent effect of improving the aesthetics of the road while reducing the risk of accidents while improving the quality of traffic signs, ease of installation and repair, and maintenance costs.
