The present invention relates to a transparent lightweight cantilever windshield having a function.

Generally, a windshield is installed along the outer edge of a bridge for the purpose of securing the safety of the driver while driving in preparation for a situation in which a vehicle running on the bridge is threatened by gust and strong wind.

While the windshield has the best function to block strong winds, the windshield wall weight and the wind load acting on the bridge structure increase with the installation of the windshield wall, and the height of the installation also allows the driver to view the scenery There is a problem to be covered.

Furthermore, when a vehicle collides with a guardrail with a large energy on a bridge, accidents that fall below a guardrail and fall down a bridge frequently occur, and a preventive measure is urgently needed.

In order to solve the above problems, a technique has been developed for securing a view of a vehicle traveling on a bridge by reducing the size of a wind load generated by windshield walls by fabricating windshields of metal laths having porosity have.

As an example of such a technique, Korean Patent Registration No. 10-1024071 aims at providing windshield walls that reduce the influence of sea breezes that hinder the growth and propagation of trees, and in order to achieve this object, A contiguous end support; Vertical supports fixed upright on the top of the vertical support; Wind shields installed between the vertical supports and having an aperture ratio of 20% to 60%; A transverse support secured to the longitudinal support and extending laterally from the longitudinal support and adjacent the ground; And anchors secured to the ends of the transverse supports and extending downwardly into the ground.

In addition, as an example of another conventional technique, Korean Patent Laid-Open Publication No. 10-2011-0085065 discloses a wind tunnel forming wind path on a wind board installed on a windy bridge, spirally forming an inner wall of the wind path, A wind tunnel for a bridge is provided in which wind intensity and noise can be greatly reduced in the process of passing through a spiral when the wind tunnel flows into the wind tunnel inner wall.

However, the above-mentioned conventional windshield has a structure in which it is difficult to perform all the functions as a secondary protection facility when the vehicle faces the danger of falling over the vehicle guard rail, which also serves as safety of pedestrians. Further, There is a problem that the weight of the bridges is affected not only by the weight of the bridges but also by the wind loads.
