Description

  The present invention relates to a windproof snow fence installed along a road in a snowy area, and more particularly to a windproof snow fence in which a support for a windproof snow fence can be stored on the spot when not in use in winter.

  In general, along a road in a snowy area, a windbreak snow fence is attached in order to reduce the influence of wind and snow blown from the side of the road to the road, and snowstorm. Windproof snow fences are often used in which a plurality of net members and a plurality of horizontally long louver members are attached in the vertical direction between pillars standing at intervals along the road. In addition, a gap is provided between the lower end portion of the net member or louver material and the road surface, and the one that has the effect of blowing off snow on the road using the wind blown through the gap is also used. Yes.

  By the way, the windbreak snow fence is necessary only in winter when there is snow. Not only is it unnecessary in other seasons, but it is also necessary for drivers who use the road by using net members, louver materials, props, etc. On the other hand, various methods have been proposed for storing the wind-proof snow fence when not in use, in order to give a feeling of pressure and to damage the landscape.

  For example, a fixed support installed along a road, a fence main body rotatably supported in a plane perpendicular to the longitudinal direction of the fence between adjacent fixed supports, and the fence main body in a vertical posture. A first locking means for stopping and a second locking means for locking in a horizontal posture with the lower end facing the road side, and the fence body is supported by left and right columns rotatably supported by the fixed column A snow fence having a frame having a portion, a plurality of snow panels arranged vertically supported rotatably between right and left support portions of the frame, and a snow panel opening / closing drive mechanism for opening and closing each snow panel simultaneously Has been proposed (see, for example, Patent Document 1).

  This snow fence has a structure that can store the entire snow fence when not in use, can improve visibility from the traveling vehicle, can be stored without using power, and can be stored easily and lightly. It can be done efficiently and efficiently.

  However, the snow fence described above has the following problems. In other words, when the fence body is locked in a horizontal position, the upper end of the fence body is not supported, and therefore, vibrations tend to occur in the vertical direction in combination with the weight of the fence body itself, and the second locking means is repeatedly loaded. There is a risk that a load more than expected including the above will be applied, causing problems such as deformation. In addition, even if an outsider is placed on the fence body, a similar load is applied, which may cause a problem, which is insufficient.

  The present invention eliminates the above-mentioned problems and provides a windproof snow fence that can stably hold the storage state in consideration of the landscape when the members of the windproof snow fence are stored. To do.

In order to achieve the above object, the present invention is configured as follows.
That is, the windbreak snow fence according to the present invention is a method in which the lower end of the net member that is detachably supported between the columns is disposed above the road surface of the road, and the column is inclined downward from the road surface end of the road. Standing on a foundation block protruding from the surface, the column can be tilted toward the next column, and the tip of the tilted column is supported at a position below the road surface of the road. It is characterized in that it was made to do so.

  Further, in the windbreak snow fence according to the present invention, when the support column is tilted toward the adjacent support column, the support column tip portion may be overlapped with the upper surface of the adjacent support column tilted in the same direction. Good.

  Furthermore, in the windproof snow fence according to the present invention, when the column is tilted toward the adjacent column, the column end may be superposed on the adjacent base block.

  Moreover, in the windproof snow fence which concerns on this invention, when it inclines toward the adjacent support | pillar, you may comprise so that a step part may be formed so that a support | pillar end may not overlap with an adjacent support | pillar.

  According to the present invention, since the lower end of the net member is disposed above the road surface of the road, snow on the road surface is blown away by the wind passing through the gap between the lower end of the net member and the road surface, and the net member is supported. The supporting column is erected on a foundation block protruding on a slope inclined downward from the road surface end of the road, and the supporting column can be tilted toward the adjacent column and is tilted. Since the tip of is supported at a position below the road surface of the road, it is possible to support the column in a stable state when tilting the column in the season when the windbreak snow fence is not used. The struts are difficult to see from the road surface and can suppress the decline of the landscape.

  In the windbreak snow fence according to the present invention, when the column is tilted toward the adjacent column, if the column tip overlaps with the upper surface of the adjacent column tilted in the same direction, the column end is Corrosion such as rust can be suppressed without touching the ground. In addition, when the column is raised again, the operator can raise the tilted column without going up and down the slope, thereby improving workability.

  In addition, in the windbreak snow fence according to the present invention, when the column end is tilted toward the next column, if the column end overlaps with the next foundation block, the column end contacts the ground. Therefore, corrosion such as rust can be suppressed. In addition, when the column is raised again, the operator can raise the tilted column without going up and down the slope, thereby improving workability.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

Is a partially enlarged view of FIG. 3, FIG. 5 is a front view showing an embodiment of a storage state of the windproof snow fence according to the present invention, FIG. 6 is an enlarged vertical sectional view in the CC section of FIG. FIG. 8 is a front view showing the second embodiment of the windproof snow fence according to the present invention, and FIG. 9 is a plan view showing the third embodiment of the windproof snow fence according to the present invention.
It is.

  First, FIGS. 1-7 shows 1st embodiment of the windproof snow fence concerning this invention, FIG. 1 is the front view seen from the road side. As shown in FIG. 1, a net member 2 is erected between struts 1 erected at intervals, and a windproof snow fence P is formed. The support column 1 is a steel material having an H-shaped cross section composed of two vertical plate-like flanges 11 and a vertical plate-like web 12 arranged therebetween, and the surface thereof is subjected to treatment such as painting or plating. . In consideration of the fact that the net member 2 with a large wind pressure is installed, it is preferable to use a metal material for the support 1 such as a general H-shaped steel, aluminum, stainless steel, steel, or other molds or pipes. It can be used as appropriate. Further, a horizontal rail 13 is installed on the upper end of the support column 1 so that the space between the support columns 1 can be maintained and the rigidity of the windbreak snow fence P can be increased.

  The net member 2 has a large number of through holes and has flexibility, and the wind speed of the wind blown to the road side using resistance when the wind from the side of the road passes through the through holes. In addition, the net member 2 is vibrated by the wind, so that the snow attached to the net member 2 can be easily dropped and the through-holes can be prevented from being blocked by the snow.

  In this embodiment, the net member 2 is formed in a net shape by warp and weft made of synthetic resin fibers so that the net member 2 is knitted together at the intersection of the warp and weft so that it cannot be easily unraveled. It was made. The net member 2 is not limited to the present embodiment, and may be composed of, for example, a metal wire, or may be a resin sheet having a large number of through holes, which is required. Depending on the strength, aperture ratio, aperture diameter, etc. In the present embodiment, the net member 2 has flexibility so that the net member 2 can be wound in consideration of storage properties and ease of transportation. For example, the net member has a plurality of belt-shaped members. These may be connected to each other so as to be foldable so as to be foldable.

  As shown in FIG. 1, the lower end 21 of the net member 2 is disposed above the road surface. As a result, a part of the wind from the side of the road passes through the through hole of the net member 2 as described above, and a part of the wind bypasses the net member 2 so as to detour upward or downward. The blown wind blows through the road surface, so that the snow accumulated on the road surface can be blown away.

  FIG. 2 is an enlarged longitudinal sectional view taken along the line AA of FIG. The net member 2 is installed between the columns 1 via support members 3 that support both ends of the net member 2. The support member 3 includes a shaft member 31 having a rectangular cross section around which the net member 2 is wound, and a pressing member 32 having an L-shaped cross section that sandwiches the net member 2 between the wound shaft member 31. The support member 3 is attached to the both side ends of the net member 2 in the vertical direction, and the fixing bolt B is inserted from the web 12 of the support column 1, and is inserted into the shaft member 31 through the pressing member and the net member 2. And a washer W1 and a nut N1. And the net member 2 is stretched between the support | pillars 1 by adjusting the fastening position of the nut N1 suitably. The support member 3 may be any member as long as the net member 2 can be stretched between the support columns 1. For example, the support member 3 is connected to the support column 1 via the support portion that supports the side end portion of the net member 2 and the bolt B. The connecting part may be formed separately. In consideration of supporting the net member 2 to which a large wind pressure is applied, the support member 3 is preferably made of metal, such as pipes and shapes such as aluminum, stainless steel and steel, and plated or painted on them. A thing etc. can be used conveniently.

  FIG. 3 is a side view of FIG. The support column 1 is erected on a foundation block 4 that protrudes at an appropriate interval from a slope S that is inclined downward from the end of the road surface R of the road. A support base 5 for supporting the column 1 is attached to the upper surface of the foundation block 4. As described above, since the windbreak snow fence P is away from the end of the road surface, there is no problem in the operation of the snowplow, and the snow removed to the side of the road by the snowplow falls to the slope. The gap between the lower end of the net member 2 of the windbreak snow fence P and the road surface is not easily blocked, and the effect of blowing off snow accumulated on the road surface can be maintained.

  The support base 5 is placed on the concrete base block 4 and fixed by anchor bolts B2, and a vertical plate portion 52 formed on the base plate 51 so as to be opposed to each other with a space in the front-rear direction. The lower part of the support | pillar 1 is arrange | positioned and fixed between both the vertical board parts 52. As shown in FIG. And the upper edge part of both the vertical board parts 52 is made the same height as the road surface R of a road, or lower than it. The vertical plate portion 52 is formed with a vertical rib from the opposite surface of the opposed vertical plate portion 52, and the lower end portion of the vertical rib is joined to the base plate. In the present embodiment, two vertical ribs are provided at an interval, but a necessary number for supporting the vertical plate portion 52 may be appropriately provided.

  4 is an enlarged view of the lower part of the support column 1 of FIG. 3, (a) is an enlarged side view, and (b) is a longitudinal sectional view in the AA section of (a). The support column 1 is fixed by a fixing bolt B <b> 3 inserted from one vertical plate portion 52 of the support base 5 through the lower portion of the support column 1 to the other vertical plate portion 52. The fixing bolt B3 passes through one flange 11 in the lower part of the column 1 and passes through the insertion hole 14 formed in the web 12 and then passes through the other flange 11 so that it cannot be seen from the outside. Since the fixing bolt B3 is provided in two upper and lower stages, if one of the fixing bolts B3 is removed, the support column 1 can be tilted in the left-right direction around the other fixing bolt B3.

  The base plate 51 of the support base 5 is provided with a contact plate portion 53 that comes into contact with one surface of the vertical plate shape of the web 12 of the support column 1. As a result, when the support column 1 is tilted in the left-right direction, the tilting direction can be restricted to only one of them, and when the support column 1 is erected from the tilted state, the support column 1 is erected substantially vertically. From this state, the column 1 is not further tilted in the opposite direction, and the column 1 can be easily erected. The support base 5 is preferably made of metal in consideration of supporting the support column 1, and is formed by joining a plate or shape material such as aluminum, stainless steel, steel, etc. by welding or the like, or plating them. A coated one can be suitably used.

  5 to 7 show a state after the net member 2 is housed in FIG. 1 and the support column 1 is tilted leftward, and FIG. 5 is a partially enlarged front view showing the tilted state of the support column 1. 6 is a longitudinal sectional view taken along the line CC of FIG. 5, and FIG. 7 is a perspective view of FIG. First, in this embodiment, the net member 2 is accommodated by removing one support member 3 from the support column 1 at the end of the net member 2 and using the support member 3 as a core toward the other support member 3 side. The net member 2 is wound up, and the net member 2 is housed inside the H-shape of the column 1 with the net member 2 attached to the column 1. The support members 3 on both sides of the net member 2 may be removed from the support column 1 and stored.

  Next, at the lower part of the support column 1, the upper fixing bolt B3 is removed, and the support column 1 is tilted toward the adjacent base block 4 on the left side using the remaining lower fixing bolt B3 as a rotation axis. At this time, if the operator performs the tilting work of the column 1 while being positioned on the slope S on the side lower than the base block 4, the worker can work compared to the case of tilting a similar column standing on the horizontal plane. Since the worker can work with the support column 1 at a relatively high position, the load on the worker is reduced and workability can be improved.

  And the front-end | tip part 15 of the tilted support | pillar 1 is superposed on the upper surface of the adjacent support | pillar 1 tilted in the same direction. Thereby, since the front-end | tip part 15 of the support | pillar 1 does not contact the ground and is hold | maintained above the ground, when the support | pillar 1 tilts, corrosion, such as rust, does not occur easily at the front-end | tip part of a support | pillar by rain water. Further, since the support column 1 is tilted with the lower fixing bolt B3 as the rotation shaft, when the tip portion 15 of the support column 1 is superimposed on the upper surface of the tilted adjacent support column 1, the tip portion 15 of the support column 1 is When the support column 1 is held at a position higher than the fixed bolt B3 of the rotating shaft, the work load is further reduced when the support column 1 is tilted or erected. Since it becomes a low inclination state, rainwater etc. do not stay in the location of the support | pillar 1 and the net member 2 accommodated inside the support | pillar 1, and can prevent malfunctions, such as corrosion.

  Furthermore, in this embodiment, the tip part 15 of the inclined support column 1 is disposed between the vertical plate parts 52 of the support base 5 attached on the adjacent base block 4. Thereby, since the tilted support | pillar 1 is prevented from moving in the front-rear direction by the vertical plate portion 52, problems such as deformations that are inadvertently shifted in the front-rear direction are less likely to occur.

  In addition, the tip portion 15 of the tilted column 1 is held at a position lower than the road surface R of the road. Thereby, in the state which inclined the support | pillar 1, it is hard to see the support | pillar 1 from the driver | operator from the motor vehicle etc. which pass along a road, and a landscape is not impaired. Thus, during the period when the windbreak snow fence P is unnecessary, the windbreak snow fence P is not moved to another place, and the members such as the columns 1 of the windbreak snow fence P can be stored in the installation place.

  8 and 9 are front views showing second and third embodiments of the windproof snow fence P. FIG. The windbreak snow fence P according to the present embodiment is different from the windbreak snow fence P shown in FIGS. 5 and 7 only in the support form of the tip 15 of the support column 1 when the support column 1 is tilted. About another point, it is the same as that of the windproof snow fence P shown by FIG.

  That is, the windbreak snow fence P shown in FIG. 8 has a relatively short length of the support column 1, and when the support column 1 is tilted, the tip 15 is superposed on the adjacent base block 4. It is what is supported. About another point, it is the same as that of the windproof snow fence P shown by FIG. In addition, when the length of the support | pillar 1 is still shorter and the support | pillar 1 is tilted, when it does not overlap with the foundation block 4 and the front-end | tip part 15 is located on the slope S, it reserves in the position of the slope S. The tip 15 is prevented from coming into contact with the slope S by using a block or a spacer.

  Further, the windproof snow fence P shown in FIG. 9 is one in which the length of the support column 1 is relatively long, and a bent portion 16 is formed obliquely upward at the upper end portion of the support column 1. And when the support | pillar 1 is tilted, a folding part is superposed | polymerized on the base block 4, and is supported. About another point, it is the same as that of the windproof snow fence P shown by FIG. In addition, the form of the folding part 16 is not limited to what was formed diagonally upward with respect to the main body of the support | pillar 1 as FIG. 9 shows, for example, the folding part 16 is diagonally inclined from the main body of the support | pillar 1 It may be provided in the upward or vertical direction, and may be formed so that the tip of the bent portion 16 rises again in the same direction as the main body of the column 1. That is, when the support column 1 is formed relatively long, in the form of FIGS. 5 and 7, when the support column 1 is tilted, the overlapping portion of the support columns 1 becomes longer in the longitudinal direction of the support column 1 and the support column 1 is It may be difficult to lift, and can be selected as appropriate in consideration of the installation interval of the columns 1 and the length of the columns 1.
