Description

  The present invention relates to a protective fence used for the purpose of windproof, snowproof, sandproof, waveproof, soundproof, fall prevention or snowfall prevention, etc. It is.

  Protective fences used for windproof, snowproof, sandproof, waveproof, soundproof, fall prevention or snowfall prevention installed along the shoulders of roads, etc. ensure safe driving of vehicles etc. and safe walking of pedestrians etc. It is an important protective facility to secure. In particular, it is an indispensable facility for the passage of vehicles and pedestrians in winter when the weather conditions are unstable.

  However, such a fence is in the spring, summer and autumn seasons, when the weather conditions are stable compared to the winter, and the view through the fence is obstructed. The view could not be seen, especially on the roadside in a scenic area, which was rather annoying. Therefore, a retractable protective fence has been proposed in order to secure a view of the area along which the protective fence is installed from spring to autumn.

  This retractable protective fence is provided with a plurality of pillars standing along the shoulder of a road and the like, and a metal protective panel constructed and fixed between the pillars. Are arranged so as to be foldable, and each column is formed to be foldable by being tilted separately from the protective panel in the direction in which the columns are arranged.

  Therefore, according to this storage type protective fence, the view of vehicles and pedestrians traveling on the road is secured by folding the protective panel and each support column and storing the protective fence during the period from spring to autumn. On the other hand, while the landscape along the road can be viewed, in the winter season, functions such as wind protection, snow protection, sand protection, wave protection, sound insulation, fall prevention or snow fall prevention can be achieved by starting up the protection panel and each column. It is done.

  However, in the above-described storage type protective fence, it is necessary to perform the work of setting up the protective fence every late autumn and the work of folding the protective fence once every spring. The cost associated with the folding work is required, and there is a problem that the maintenance cost of the protective fence increases accordingly.

  The present invention has been made to solve the above-mentioned problems, and without having to set up and fold the protective fence, it can secure a view through the protective fence throughout the year, and it is windproof, snowproof, sandproof, It aims at providing the protection fence which can maintain functions, such as a wave prevention, sound insulation, fall prevention, or snowfall prevention.

  In order to achieve this object, the guard fence according to claim 1 is provided with two or more struts erected at a predetermined interval, and the struts are erected and fixed between the respective struts and above the road surface. In a transparent and flat panel made of glass that is arranged in a range corresponding to the height of the window of a passing vehicle or the height of the pedestrian's eyes in the height direction of the vehicle, and a portion excluding the range of the transparent panel And a protective panel that is installed and fixed between the columns.

  According to the protective fence of claim 1, since the transparent panel is disposed in a range corresponding to the height of the window of the passing vehicle or the sight line of the pedestrian, the occupant or pedestrian of the passing vehicle can travel on the road surface. While traveling or walking, you can see the scenery behind the protective fence through this transparent panel. Further, a protective panel, for example, an opaque or transparent protective panel made of metal or resin, which has been conventionally used, is disposed in a portion excluding the range where the transparent panel is disposed. For this reason, the manufacturing cost can be reduced compared with the case where the entire protective fence is made of a transparent glass panel, and the strength of the entire protective fence is prevented from being reduced compared to the case where the entire protective panel is made transparent. Is done.

  According to the guard fence of the present invention, as in the case of a conventional retractable guard fence, the work of setting up the guard fence in the late autumn period and the work of folding the guard fence in the early spring period are not performed once a year. Just install it, you can see the scenery beyond the protective fence through the transparent panel throughout the year, and the height of the protective fence does not change throughout the year, windproof, snowproof, sandproof, There is an effect that a protective function such as wave prevention, sound insulation, fall prevention or snowfall prevention can be sufficiently exhibited. In addition, there is an effect that the maintenance management cost of the protection fence can be reduced by the amount that costs associated with the startup work and the folding work of the protection fence become unnecessary.

  In addition, since there is no need for a mechanism for starting up and folding, which is required for conventional retractable protective fences, the number of parts of the protective fences is small, and the overall structure of the protective fences can be simplified. It has the effect of being easy to do. Moreover, since the transparent panel is made of flat glass, there is no distortion like a transparent panel made of synthetic resin even if its area is increased, and it can prevent distortion of the scenery seen through the transparent panel and is transparent. There is an effect that visibility through the panel can be improved.

  Furthermore, since the transparent panel is made of glass, even if it is exposed to a high temperature due to the occurrence of a vehicle fire or the like, it does not melt like a resin-made transparent panel. Further, since the transparent panel is made of glass, the photocatalyst film can be formed by baking the photocatalyst coating material on the glass surface.

  In such a case, dirt on the surface of the transparent panel is decomposed and purified by the self-cleaning action of the photocatalyst. As a result, the transparency can be maintained without cleaning the transparent panel, and the hydrophilicity of the photocatalyst can be maintained. It has the effect of maintaining a good view through the glass even in rainy weather. In addition, the baked photocatalyst film is highly integrated with the surface of the transparent panel, and has the effect of improving its durability.

  Here, as the transparent panel, for example, a reinforced laminated plate glass obtained by bonding a reinforced plate glass and a meshed plate glass through a transparent and adhesive intermediate film can also be used. In this case, the transparent panel made of tempered laminated glass has transparency as a matter of course, and can also exhibit sound insulation for blocking the running sound of the vehicle.

  Moreover, the tempered flat glass on the road side is damaged by a collision of a vehicle or the like by fixing the transparent panel between the columns with the transparent panel netted glass facing the private side, the tempered glass facing the road side, and the transparent panel. Even in this case, the scattering of the fragments is suppressed by the intermediate film, and the scattering of the fragments to the private side is prevented. Further, even if the meshed plate glass is broken, the fragments are prevented from scattering to the private side due to the adhesiveness of the intermediate film and the mesh in the glass.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of a blowing type snow fence 1 (hereinafter simply referred to as “snow fence 1”) which is an embodiment of the protection fence of the present invention. In FIG. 1, only a part of the through holes formed in the entire surface of the snowproof panel 3 disposed on the upper side of the transparent panel 4 is illustrated.

  As shown in FIG. 1, the snow fence 1 is installed at an installation location along the shoulder 51 of the road 50 (see FIG. 3), and the wind and snow flow from the windward side (right side of FIG. 3) is on the leeward side (left side of FIG. 3). This is a kind of protective fence for preventing the air from being blown into the road 50. The snow fence 1 is provided with two or more support columns 2, 2,... Standing at predetermined intervals along the installation site, and the lower ends of these support columns 2 are embedded in the ground of the installation site. It is fixed in a state of being embedded in the foundation concrete 52.

  Each support column 2 is formed by processing, for example, an H-shaped steel material, and a transparent panel 4 and a snowproof panel 3 are vertically installed and fixed between the support columns 2 and 2. Here, the snowproof panel 3 is installed and fixed on the upper and lower parts between the columns 2 and 2, respectively, and the transparent panel 4 is installed only on the middle part between the columns 2 and 2. And fixed.

  The snow-proof panel 3 is a metal panel formed in an opaque and corrugated shape, and has a rigidity and strength comparable to those of the transparent panel 4. The snow protection panel 3 is disposed from the upper end edge of the transparent panel 4 to the upper end of the column 2, and is disposed from the lower end edge of the transparent panel 4 to the vicinity of the lower end of the column 2. In addition, both ends of the snowproof panel 3 in the lateral direction are loosely inserted into the inside of the column 2 from the side surfaces of the column 2, and both ends in the lateral direction are fastened and fixed to the column 2 by bolts and nuts, respectively.

  The material of the snowproof panel (protective panel) is not necessarily limited to a metal one, and may be a transparent or opaque synthetic resin panel (folded plate) formed in a corrugated plate shape. .

  Furthermore, the snow-proof panel 3 is formed of a folded plate bent in a substantially trapezoidal shape when viewed in cross section (see FIG. 3), and the folded plate of the snow-proof panel 3 disposed on the upper side of the transparent panel 4 includes A perforated folded plate 3A having a large number of through holes formed on the entire surface is used, and a non-folded folded plate 3B having no through holes is used as a folded plate of the snowproof panel 3 disposed below the transparent panel 4. It has been.

  The transparent panel 4 is a transparent glass panel formed in a substantially rectangular flat plate shape when viewed from the front, and is erected and fixed between the columns 2 and 2 via a panel holding frame 5. The panel holding frame 5 has an upper end edge 5 a connected and fixed to a lower end edge of the snow protection panel 3 disposed on the upper side of the transparent panel 4 without a gap, and the lower end edge 5 b is below the transparent panel 4. It is connected and fixed without any gap to the upper edge of the snow protection panel 3 disposed on the side.

  The panel holding frame 5 is formed in a substantially rectangular frame shape when viewed from the front, and the transparent panel 4 is held in an opening 5c provided in the inner periphery thereof. The panel holding frame 5 has both ends in the lateral direction (left and right in FIG. 1) loosely inserted into the inside of each column 2 from the side surface of each column 2, and both ends in the horizontal direction are screwed thereto. It is being fixed to the support | pillar 2 while being press-contacted to the inner surface of each support | pillar 2 via the spring fixing tool 6 (refer FIG. 2). FIG. 2 is a cross-sectional view showing a state in which the panel holding frame 5 is fixed to the support 2.

  3 is a longitudinal sectional view taken along line III-III in FIG. As shown in FIG. 3, the column 2 includes a vertical portion 2 </ b> A that extends substantially straight upward from the foundation concrete 52, and an upper end portion of the vertical portion 2 </ b> A toward the road 50 (left side in FIG. 3). And a curved portion 2B extending upward while being curved in a substantially arc shape. In this support column 2, a snowproof panel 3 is fixed to the lower half of the vertical portion 2A, a transparent panel 4 is fixed to the upper half of the vertical portion 2A, and a snowproof panel 3 is fixed to the curved portion 2B.

  The transparent panel 4 is disposed above the road surface 50a of the road 50 and in a range corresponding to the height of the passing vehicle window or the pedestrian's line of sight in the height direction of the column 2. For this reason, a passenger on a vehicle traveling on the road 50 or a pedestrian walking on the road 50 travels or walks on the road surface 50a of the road 50 throughout the year regardless of the season, and snow-prevents through this transparent panel 4. You can see the scenery on the other side of the fence 1.

  In addition, if the arrangement | positioning range of the transparent panel 4 is illustrated using a concrete numerical value, the height from the road surface 50a to the lower end part of the transparent panel 4 shall be about 0.5 m, and the vertical width of transparent panel 4 itself is set to the height. The height from the road surface 50a to the upper end of the transparent panel 4 is preferably about 2.0 m.

  Further, since the transparent panel 4 and the snowproof panel 3 disposed below the transparent panel 4 are disposed in the vertical portion 2A of the support column 2, the transparent panel 4 and the snow protection panel 3 become vertical wall surfaces that rise substantially perpendicular to the ground of the installation site. The snowproof panel 3 disposed on the upper side of the panel 4 is a curved wall surface that is curved in a substantially arc shape toward the road 50 side (leeward side, left side in FIG. 3). For this reason, the snowstorm flow flowing from the windward side to the leeward side is blown off further to the downstream side than the road 50 over the road surface 50 a along the curved wall surface of the snow fence 1.

  In addition, as described above, the perforated folded plate 3A is used for the snow protection panel 3 forming the curved wall surface of the snow fence 1 so that the flow toward the leeward side beyond the upper end of the snow fence 1 is disturbed in a Karman vortex. It is suppressed. Moreover, since the non-porous transparent panel 4 and the snow-proof panel 3 made of the non-hole folded plate 3B are used in the portion forming the vertical wall surface in the snow fence 1, the snowstorm flow passes through them into the road 50. Blowing is prevented.

  4 is an enlarged cross-sectional view of the transparent panel 4, and is a partial enlarged view of FIG. As shown in FIG. 4, the transparent panel 4 includes, for example, a transparent reinforced plate glass 4a and a transparent mesh-containing plate glass (plate glass in which the mesh material 4d is embedded) through an intermediate film 4c having transparency and adhesiveness. It is formed with the reinforced laminated plate glass which bonded together. This tempered laminated glass is transparent while interposing the intermediate film 4c, and also has sound insulation due to the interposition of the intermediate film 4c.

  In addition, the transparent panel 4 has a screen glass 4b directed toward the private land and a tempered glass plate 4a directed toward the road 50. Mounted and fixed. Moreover, the transparent panel 4 is formed with flat glass, and even if the area is large, distortion like the transparent panel 4 made of synthetic resin is prevented.

  For this reason, the sight which enters the field of view of a vehicle occupant or a pedestrian through the transparent panel 4 can be visually recognized without being distorted. Moreover, since the transparent panel 4 is made of glass, it can be prevented from melting like the resin-made transparent panel 4 even if it is exposed to a high temperature due to the occurrence of a vehicle fire or the like.

  A thin photocatalyst film 4e is formed on the glass surface of the transparent panel 4 by baking the photocatalyst coating material. By this photocatalyst film 4e, the dirt on the surface of the transparent panel 4 is decomposed and purified, and the transparency of the transparent panel 4 is maintained. Therefore, the transparent panel 4 does not need to be cleaned and can maintain a good view through the glass even in rainy weather.

  As described above, according to the snow fence 1 of the present embodiment, the transparent panel 4 is disposed in a range corresponding to the window height of a passing vehicle or the pedestrian's eye level. Like the fence, it is possible to set up the snow fence in late autumn and the snow fence in the early spring without folding it once a year. The passenger or pedestrian of the passing vehicle can view the scenery beyond the snow fence 1 while traveling or walking on the road surface 50a.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above embodiments, and various modifications can be easily made without departing from the spirit of the present invention. It can be guessed. For example, in the present embodiment, the case where the protective fence of the present invention is applied to the blown snow fence 1 has been described. However, the embodiment of the present invention is not necessarily limited to this, and the protective fence for other uses is used. For example, the present invention may be applied to a windbreak fence, a sandproof fence, a wavebreak fence, a soundproof fence, a fall prevention fence, or a snowfall prevention fence.

  In this embodiment, the installation location of the snow fence 1 which is a kind of the protection fence is described as the road shoulder 51 of the road 50. However, the installation location of the protection fence is not necessarily limited to the road 50. Or along the sidewalk, along the coastline, along the promenade. Moreover, in the present Example, although the upper part of the snow fence 1 was formed in the shape of a curved wall surface, the form of this snow fence is not necessarily limited to this, and the whole from the upper end to the lower end of the snow fence is a vertical wall surface shape. It may be a form.

  Further, in this embodiment, the snow protection panels 3 are arranged on both the upper and lower sides of the transparent panel 4, but the location of the snow protection panels 3 is not necessarily limited to this, and the height of the transparent panel 4 is the vehicle window. If it falls within the range corresponding to the height or the pedestrian's line of sight, a snow-proof panel is placed only on either the upper or lower side of the transparent panel, depending on the relationship between the height of the column and the height of the road surface. You may make it install.

  In this embodiment, the perforated folded plate 3A is used as the snowproof panel 3 disposed on the upper side of the transparent panel 4, and the non-perforated folded plate 3B is employed as the snowproof panel 3 disposed on the lower side of the transparent panel 4.
