Abstract
[0001] The present invention relates to a multi-joint bollard having a strong holding force of a lower portion, and more particularly, to a multi-joint bollard having a lower strong holding force, It is possible to provide a strong supporting force to the lower portion of the strut so as to more easily prevent the strut from being broken due to the external impact, It is possible to more easily reinforce the weak joining portion of the lower portion of the elastic layer and the lower portion of the strut and the weak joining portions of the upper strut, the lower strut and the plurality of intermediate struts of the strut through the elastic layer, So that the elastic layer can be injected into the mold for foamable molding, The upper and lower lengths of the struts can be more easily adjusted and the strut, the elastic layer, and the protective layer can be more stably fixed to the ground, It is effective.
Description
According to the present invention, an external impact such as a vehicle collision applied to the strut through the elastic layer formed on the outer surface of the strut and the foam layer formed on the outer surface of the elastic layer can be more easily buffered, It is possible to provide a strong supporting force to the lower portion of the support so as to more easily prevent breakage due to the bending of the elastic layer and to prevent the damage of the lower portion of the support via the reinforcing portion formed at the lower portion of the elastic layer, It is possible to more easily reinforce the joining portion and the weak joining portions of the upper strut, the lower strut and the plurality of intermediate struts of the strut, as well as being able to be injected into the expandable formwork as the foaming liquid passes over the outer surface of the reinforcing portion The elastic layer can be easily manufactured together with the struts through insert injection molding at one time, Edinburgh, it relates to a joint bollard as well as the vertical length of the pillar can be easily controlled than with the holding, the elastic layer, and a strong force of the lower portion in the protective layer may be a fixed position to a more stable ground.
In general, it is a safeguard to protect people in a certain area, to prevent entry of vehicles which are installed at the entrance of a road, a boundary of a road, a park, a performance hall, a playground, etc.,
Such a bollard generally has a structure in which a stone column is buried in the ground and protruded upwardly or has a structure in which it is buried in the ground as a rod of metal and protrudes upward. A plurality of chains are installed and operated at intervals, and recently, a chain drawn out to the inside of a hollow tube-shaped bollard having a hollow portion therein is formed to be wound around a bobbin, and the chain is automatically returned It is possible to prevent the entry of a vehicle into a bollard installation place as well as the entry of a person by a chain drawn from the bobbin if necessary, and in particular, to have a chain structure that is automatically restored and wound, A bollard having an anti-entry chain is disclosed in Korean Patent Laid- 0-2013-0104136.
However, the bollard proposed in Korean Patent Laid-Open Publication No. 10-2013-0104136 (bollard having an anti-entry chain) can not cushion an external impact such as a vehicle collision and is bent by an external impact such as a vehicle collision There is a problem that it is broken.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide an elastic layer formed on the outer surface of a strut and a protective layer formed on the outer surface of the elastic layer, It is possible to provide a strong supporting force at the lower portion of the strut so as to more easily prevent the strut from being broken due to the external impact due to its easy buffering, It is possible to more easily reinforce the weak joining portion of the lower portion of the elastic layer and the lower portion of the strut and the weak joining portion of the upper strut, the lower strut and the plurality of intermediate struts of the strut, The elastic layer can be injected into the foamable mold by passing through the insert, The upper and lower lengths of the strut can be more easily adjusted, and the lower strut, the elastic stratum, and the protective layer can be more stably fixed on the ground. It is an object of the present invention to provide a multi-joint bollard having a strong supporting force.
According to an aspect of the present invention, And a resilient layer formed on an outer surface of the strut. The polyolefin bollard according to claim 1,
A first protrusion protruding inwardly of the elastic layer is formed on the outer surface of the lower portion of the strut, and a first groove recessed inward of the strut is alternately formed in the vertical direction of the strut, And a second protrusion protruding in the first groove direction of the strut and inserted into the first groove are formed on the upper and lower surfaces of the elastic layer, Direction, as shown in Fig.
It is preferable that a reinforcement portion protruding in a lower outer direction of the elastic layer and reinforcing a lower portion of the elastic layer is formed on a lower outer surface of the elastic layer.
Further, it is preferable that the elastic layer is insert injection-molded together with the struts.
Furthermore, the strut may include an upper strut and a lower strut; And an intermediate strut disposed between the upper strut and the lower strut, wherein the elastic strands are formed on an outer surface of the upper strut and the lower strut respectively; And an intermediate elastic layer formed on an outer surface of the intermediate strut.
In addition, it is preferable that a protective layer for protecting the elastic layer and the strut is formed on an outer surface of the elastic layer.
In addition, it is preferable that the protective layer is formed by foam molding on the outer surface of the elastic layer.
The outer diameter of the protective layer may be gradually increased from the upper portion of the protective layer to the lower portion of the protective layer.
Here, the protective layer may be formed on the upper surface of the elastic layer, and may have an outer diameter gradually decreasing from the upper portion to the lower portion. And a lower protective layer formed on an outer surface of the elastic layer located in a lower direction of the upper protective layer and having an outer diameter gradually increasing from the upper portion to the lower portion.
In addition, it is preferable that the reflective layer is provided on the outer surface of the protective layer between the lower part of the upper protective layer and the upper part of the lower protective layer.
According to the present invention, an external impact such as a vehicle collision applied to the strut through the elastic layer formed on the outer surface of the strut and the foam layer formed on the outer surface of the elastic layer can be more easily buffered, The elastic layer can have a strong supporting force at the lower portion of the strut so that it can be more easily prevented from being broken by being bent by the elastic layer and the reinforcing portion protruding in the lower outer direction of the elastic layer from the lower portion of the elastic layer, And the weak joining portions of the strut and the upper strut, the lower strut, and the plurality of intermediate struts of the strut can be more easily reinforced, and the foamed liquid can be easily passed through the outer surface of the reinforcing portion, So that the elastic layer with the struts can be easily injected through insert injection molding The vertical length of the strut can be more easily adjusted according to the number of the plurality of intermediate struts, and the outer diameter of the stratum can be gradually increased from the upper portion of the protective layer to the lower portion, The elastic layer and the protective layer can be more stably fixed to the ground.
