Abstract

<P>PROBLEM TO BE SOLVED: To provide a snow sliding plate, preventing a snow block from dropping from an overpass to prevent an accident of an automobile running under the overpass and dropping the snow before it lies thick. <P>SOLUTION: An inclined snow sliding plate is mounted on a projecting part formed between the cross-direction edge of the land bridge and a guard rail or a handrail provided thereon, whereby the falling snow is prevented from lying thick and the snow is dropped by the snow sliding plate not to give any shock to the automobile running under the overpass. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a snow accretion prevention structure, and more particularly, to a snow removal device for a road structure that constantly removes a snow mass stuck to a structure installed above a road in a heavy snow region.

Conventionally, in heavy snow areas that have been snowing throughout the winter, the accumulated snow is stuck on the structures installed on the main road and stuck as snow masses, and when the daytime temperature rises, the ice and snow masses loosen on the road. Fall on the road, hit a vehicle in traffic, or fall on the road and cause an accident.
Japanese Patent Laid-Open No. 2001-23087

  The known example has a structure in which a fence is provided on the indicator lamp of a traffic light and a snow remover is provided to scrape off snow. Since the scraper is provided, there is anxiety in operation during the snowy season. It has also been developed to melt snow by installing heaters on traffic lights and road sign boards.

  The inventor has arrived at the present invention as a result of intensive research for the purpose of safety on road traffic in this heavy snow region, and the present invention uses an inclined sliding plate before the snow becomes a lump. It is a structure that slides little by little, or provides a snow cutting board to divide and fall snow blocks, so that snow falls in a small amount without landing before it becomes snow blocks. There is no risk of accidents even if it hits the vehicle body or falls on the road.

  As a structure to be an object of the present invention, a bridge-type pillar hanging over a river, a step portion on the side of an overpass, an aqueduct, a signal lamp, a road sign board, or the like can be considered.

  And as a sliding board, since it is necessary for it to be a smooth surface to which snow does not adhere, a synthetic resin board and the coated iron plate are suitable.

  As described above, the present invention can be applied to the case where the snow falling on the slightly protruding portion of the bridge end of the road bridge straddling the highway or the main road falls as a snow lump or ice lump to the lower road, or a similar high speed. Snow on the rung of a guide board provided on a road or main road falls as a lump and prevents an accident to a vehicle passing through a lower passage.

  In the present invention, as shown in each claim and each drawing, by attaching an inclined snow sliding board to a bridge or a structure on the road that crosses an expressway or a main road, Before it becomes an ice and snow mass, it falls by the snowboard and a big shock is avoided.

  Also, when using gable-type snow slides for structures, the snow piled up by vertically installing the snow-breaking plate on the roof top is divided into left and right and falls downward, so the snow is a large lump. It will not be.

  Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an explanatory diagram of an edge portion of an overpass that crosses over a highway or a main road, and shows the structural diagram described in claims 1 and 2, wherein (1) shows the foundation concrete of the curb of the overpass, (2) indicates a guardrail or balustrade handrail erected on the curbstone (1).

  Stepped protrusions are formed in the planted portions of the curbstone (1) and guardrail (2), and when snow falls, the protrusions are piled up with snow and finally fall. At this time, in the case of a snow lump, if it hits a running car, it is essential to have a big accident, and if a snow lump appears suddenly on the road, There is a risk of accidents.

  It is the snowboard A of the present invention that solves this, and the snowboard A used in the snow removal apparatus of the present invention is, as shown in the figure, between the foundation concrete of the curbstone (1) and the guardrail (2). By applying a single-flow type inclined plate to the convex stepped portion, snowfall slides down without accumulating on the convex portion. For this reason, the amount of this fall is small, and it does not give a big shock to the car running under the bridge.

  FIG. 2 shows an embodiment of the snowboard A used for the guide plate (3) as a structure on the road described in claim 3, which is formed in a side-like shape. When the short side of the snowboard A which is the roof is turned to the display surface side of the guide plate (3), it is not difficult to see even while the car is running, and the long side hangs on the plate attachment (4) The accumulated snow will not fall into a large lump but will fall down, preventing a major accident.

  FIG. 3 is an embodiment diagram of claim 4 for a structure such as an aqueduct, and the roof as the snow sliding board A is formed in a gable shape.

  The snow extinguishing plate A shown in FIGS. 2 and 3 has a top portion. It is one Example of the snow sliding board A of this invention, Comprising: The snow cutting board B is standingly arranged perpendicularly | vertically at this top part. By providing this snow cutting board B, the snow mass piled up in a mountain shape at the top is divided into left and right and falls, so that it does not fall on the road as a large mass.

  FIG. 4 shows another embodiment of the cantilevered snowboard A. The snowboard A is made of an acrylic resin that is particularly large and easily slid, and has a slightly spherical surface, and is suitable for use in a special place.

  Further, although not shown in the drawings, the structure on the road is suitable as an object to be laid on the entrance of the tunnel or the gate-type support of the iron bridge.

  The present invention eliminates car accidents caused by ice and snow blocks falling from bridges straddling highways and main roads in the northern heavy snow region, or from guide boards and sign boards provided on these roads. It can be used widely and can contribute to traffic safety.
