Description

Bollards to prevent entry into vehicles {A BOLLARD}

The present invention relates to a vehicle entrance prevention bollard, and more particularly to a vehicle entrance prevention bollard is minimized damage and easy to maintain.

In general, bollards are installed at the boundaries of bogies and roadways to prevent traffic from entering the sidewalks, thereby preventing pedestrian safety and traffic, and to prevent damage to the sidewalks that may occur when the vehicle is parked or stopped. It will perform the function.

These bollards are mainly made of stone, concrete, or steel, and have the advantage of preventing the entry of the vehicle as a material property resistant to impacts, while being easy to damage, while making the bollards expensive and difficult to transport and install. In addition, there was a fear of injury due to the lack of shock absorbing function in case of bumping in walking process.

In consideration of this, in recent years, a metal support tube is embedded in the ground to protrude to a predetermined height, and an elastic cushion cover is placed on the outer peripheral surface of the protruding support tube, and the interior of the buffer cover at the upper part of the support tube forms a hollow portion. If it bumps, it is bent so that there is no risk of injury.

However, when the conventional bollard is broken, there is a problem in that the entire bollard buried in the ground needs to be replaced, thereby making it difficult to maintain and increasing maintenance costs.

Therefore, the problem to be solved by the present invention is to provide a bollard for preventing entry to the vehicle to minimize the damage by minimizing the impact, to facilitate the maintenance of the parts individually.

In order to solve the above problems, the vehicle entrance preventing bollard according to an embodiment of the buried pipe buried in the ground; A nut installed to be fixed to an upper surface of the buried pipe; A spring installed at an upper portion of the buried pipe to mitigate an impact; A spring support covering an upper portion of the spring; A long bolt fastened to the nut from the upper side of the spring support to tightly fix the spring support and the spring; An inner circumferential surface in close contact with an outer circumferential surface of the spring support to be fixed to the spring support; A post that is fitted to the reinforcement and surrounds the reinforcement; And a fixing screw fastened around the outer circumferential surface of a point corresponding to the spring of the support to penetrate the support and the reinforcement and having an end portion penetrated to the inner side of the spring to fix the support to the support.

According to the bollard for preventing entry to the vehicle according to the present invention, the impact is minimized when the collision of the vehicle is minimized, and the parts can be individually replaced, easy to maintain, and there is an effect that the maintenance cost can be reduced.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to accomplish them, will become apparent by reference to the embodiments described in detail below with reference to the accompanying drawings.

However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms. It is provided to fully inform the scope of the invention, and the invention is defined only by the scope of the claims.

Hereinafter, with reference to the accompanying drawings will be described in detail for the vehicle entrance preventing bollard according to an embodiment of the present invention.

1 is a cross-sectional view showing the configuration of a vehicle entrance preventing bollard according to an embodiment of the present invention, Figure 2 is a partial cut-away enlarged sectional view of Figure 1, Figure 3 is an enlarged cross-sectional view B portion of FIG.

Vehicle entry prevention bollard according to an embodiment of the present invention as shown in Figures 1 to 3 buried pipe 11, nut 12, spring 13, spring support 14, long bolt 15, reinforcement ( 16), the strut 17, and the set screw 18.

The buried pipe 11 is formed in an overall cylindrical shape, the upper part of which is blocked by a disk 11a, and the lower part is opened. A through hole 11b is formed in the center of the disk 11a. Buried.

The nut 12 is for fastening the long bolt 15 which will be described later. The nut 12 is welded and fixed to the upper surface of the buried pipe 11, that is, at the center of the disc 11a to correspond to the through hole 11b.

The spring 13 is seated in the center on the disc 11a of the buried pipe 11, and is installed to mitigate the impact when the vehicle collides with the bollard installed.

The spring support 14 is formed in the cylindrical shape which the bottom face opened, and is installed in the upper part of the spring 13 covering the upper part of the spring 13. An insertion hole 14a is formed in the center of the upper surface.

The long bolt 15 is inserted into the insertion hole 14a from the upper side of the spring support 14 and fastened to the nut 12 so that the head portion presses the upper surface of the spring support 14 to some extent so that the spring support 14 and the spring ( 13) to be fixed in close contact.

The reinforcement 16 is formed of an elongated cylindrical pipe and is fitted to the spring reinforcement 16 so that the spring reinforcement 16, the spring 13, and the long bolt 15 are installed at the lower inner side thereof. It is pinned and the lower end is spaced apart from the upper surface of the buried pipe 11.

The strut 17 is formed of a synthetic resin material and is fitted to the reinforcing rod 16 so as to surround the reinforcing rod 16, and various characters may be engraved on the outer surface by laser processing.

The fixing screw 18 is fastened to the lower portion of the support 17, that is, around the outer circumferential surface at a point corresponding to the spring 13, penetrating the support 17 and the reinforcing bar 16, and the end portion of the support screw 18 is extended to the inside of the spring 13. It is penetrated to fix the strut 17 to the reinforcement.

On the other hand, the upper surface of the reinforcing rod 16 and the support (17) is open so that the end cap 19 is coupled to the upper end of the support (17) and the reinforcing bar (16).

The vehicle entry preventing bollard according to an embodiment of the present invention, the buried pipe 11 is installed on the ground of the road to be installed in the center line of the road, etc. to prevent the entry of the vehicle, the vehicle is a post (17) ), The support 17 and the reinforcement 16 are inclined in a direction opposite to the collision direction of the vehicle. At this time, the spring 13 inside the reinforcement 16 is bent to absorb the shock and compress the spring 13 at the same time. Elasticity, and when the external force is removed, the strut 17 and the reinforcement 16 are vertically restored by the elasticity of the spring 13.

As such, the shock is mitigated by the spring 13 to minimize the damage to the strut 17.

On the other hand, the vehicle entry prevention bollard according to an embodiment of the present invention buried pipe buried in the ground when the strut 17 is damaged due to frequent collision of the vehicle, or the bollard is damaged due to corrosion, etc. due to long-term use Only the damaged and damaged parts can be easily replaced without the need to replace the entire bollards, including (11).

That is, when the support (17) is damaged and the support (17) needs to be replaced, the fixing screw (18) for fixing the support (17) is separated from the reinforcing bar (16) and the support (17), and then the support (17) and Removing the finishing cap 19 fastened to the reinforcing bar 16 and can be replaced with a new post 17 by separating the strut 17 from the reinforcement 16. In this way, the support post 17 can be separated only by removing the fixing screw 18, so that the support post 17 can be easily replaced.

In addition, if you need to replace both the support (17) and the reinforcing bar (16), after removing the fixing screw 18, remove the closing cap (19) and separate the support (17). And when the long bolt 15 is separated from the nut 12 for the separation of the reinforcing bar 16, the spring support 14 is free to easily remove the reinforcing bar 16 fixed to the spring support 14 and then a new reinforcing bar ( It is easy to replace with 16).

Therefore, the vehicle entry prevention bollard according to an embodiment of the present invention is to minimize the damage when the collision of the vehicle is minimized, it is possible to replace the parts individually, easy maintenance, maintenance cost can be reduced.
