Description

  The present invention relates to a perforated fence made of a steel plate, and particularly to a perforated fence such as windproof snow corresponding to natural conditions (wind, snow, sand, waves, solar radiation, etc.) depending on the direction of the installation location.

  In snowfall areas, seasonal winds (mainly winds from north to west) blow in a certain direction when snowing during the winter, and winter enclosures around the house are performed to prevent it. In the traditional winter fence, it is removed from spring to autumn because it interferes with sunlight and ventilation.

  In addition, wind and snow fences are installed from the north side to the west side to prevent wind and snow damage on the roads and railways. Even in this windbreak snow fence, it is removed and folded from spring to autumn in order to improve visibility in consideration of the landscape.

  However, it is cumbersome to install them at the end of autumn and remove or fold them in early spring. It is desirable to be able to keep it installed year-round by incorporating a function that can cope with the natural conditions of the place where the fence is installed.

  Therefore, as having a function that can cope with the natural conditions of the place where the fence is installed, only the bottom side of the sawtooth bulge part of the fence provided with multiple stages of horizontal sawtooth bulge parts in the vertical direction is provided. Technologies provided with ventilation holes are disclosed in Japanese Utility Model Publication No. 54-34437, Japanese Utility Model Application Publication No. 55-80445, and Japanese Patent Application Laid-Open No. 2006-90116.

  According to these devices and the like, it is said that there is a certain degree of ventilation, the direction of the wind is deflected upward, blinding that hinders visual recognition, and solar radiation from which sunlight enters from a certain direction.

  Japanese Laid-Open Patent Publication No. 2002-89086 discloses a technique in which a plurality of horizontal slit-like holes are provided on a non-parallel surface of a fence in which vertical wavy bulging portions are provided in multiple stages in the left-right direction. .

  According to this invention, it is said that the wind is removed so as not to receive a large wind force, the blinding effect is great, and the wind and sandproof functions are improved.

  In addition, a technology for arranging a large number of through-holes in a vertical plate portion perpendicular to the ground and to the whole of the dredging panel of the dredging panel provided with vertical sawtooth-like bulging portions in multiple stages in the left-right direction Is disclosed in Japanese Patent Publication No. 58-57595.

  According to this invention, it is said that ventilation can be obtained through the through-holes while maintaining blindness.

  Moreover, the technique which provided many through-holes only in the single side | surface of the axisymmetric bulging part which concerns on the creation of this applicant is shown in the design registration 1397173 gazette and the design registration 1397174 gazette.

  In addition, the techniques disclosed in Japanese Patent Application Laid-Open No. 2002-89086 and Japanese Patent Publication No. 58-57595 having a bulging portion in the vertical direction show that a certain amount of ventilation is obtained, but wind, snow, sand・ It is not shown how to deal with natural conditions such as waves and solar radiation depending on the direction of the installation location.

  Therefore, an object of the present invention is to provide a perforated fence such as wind and snow that can cope with natural conditions depending on the direction of the installation location.

  The perforated fence of windbreaking snow or the like according to the invention of claim 1 is provided between a plurality of elongate horizontal beams 11, 12, 13 and a plurality of horizontal beams 11, 12, 13 horizontally passed between a pair of columns 10. In a perforated fence 1 in which perforated windbreaking snowboards 20 with the vertical direction as a longitudinal direction are mounted side by side, the windbreaking snowboard 20 is linearly attached to both ends of the bulging portion 22 and the bulging portion 22 that are axisymmetric in plan view. The straight attachment portion 21 of the windproof snowboard 20 is fixed to the horizontal rails 11, 12, and 13 and a large number of through holes 23 are provided only on one side of the symmetric bulging portion 22.

  According to the first aspect of the present invention, the windproof snow plate 20 is composed of a bulging portion 22 that is line-symmetrical in plan view, and straight mounting portions 21 at both ends of the bulging portion 22. Is fixed to the horizontal rails 11, 12, and 13 and a large number of through holes 23 are provided only on one side of the symmetric bulging portion 22, so that the windbreak snowboard 20 is blocked in the direction and passage of wind and light. -Since the direction of transmission can be achieved, for example, the through hole 23 faces southward, so that it can cope with natural conditions depending on the direction of the installation location.

  In addition, the windproof snowboard 20 can be mounted upside down on the windproof snowboard 20 by making the bulging part 22 line-symmetric in the plan view and the straight attachment parts 21 at both ends of the bulging part 22. For example, even if a through-hole 23 is provided on the right side of the windproof snowboard 20, it can be mounted upside down to meet natural conditions depending on the direction of the installation location.
