Description

  The present invention relates to a snowfall protection fence that is used in a snowy area and is suitable for preventing snow that slides down from a roof or the like from flowing into an adjacent land or the like.

  In snowy areas such as Hokkaido and Tohoku, the treatment of snow falling on the roof is a very important issue. Recently, the number of buildings with snow-free roofs that prevent snow from sliding off the roof has increased, but in consideration of design issues such as aesthetics and the negative effects on the buildings due to the weight of snow, they have fallen on the roofs. There are many buildings that use so-called triangular roofs that allow snow to fall to the ground or single-flow roofs.

Conventionally, with respect to snow sliding from the roof, in order to prevent the snow from flowing into the adjacent land, a snowfall protection fence is installed near the boundary with the adjacent land, and the snowfall protection fence prevents the snow from flowing into the adjacent ground. As an example of such a snowfall protection fence, a snow stop fence described in Utility Model Registration No. 3087200 is known. The snow fence described in the publication is configured so that a wire rope is stretched between poles erected at intervals, and snow or a snow lump that has slipped off the roof by the wire rope is received. According to the present invention, it is said that the scattering of snow is prevented, and the sun or the like is not deteriorated by removing the wire or the pole in a season without snow.

  Alternatively, a plurality of steel materials processed according to the size of the site are erected, and between the steel materials, for example, a steel plate processed into a mesh shape as a member that receives snow falling from the roof or a block of snow, There is also a one-piece snowfall protection fence (fence) that is constructed by erection between steel materials erected as a snow stop member.

However, in the case of the snow guard fence described in the above-mentioned utility model registration No. 3087200, since it has a structure for receiving snow by a wire, when the amount of snow sliding from the roof is large, the wire is loosened and a sufficient snow prevention effect is obtained. Not expected. Especially in snowy areas, the amount of snow that slides down from the roof is enormous, and the wire stretched between the poles is insufficient, and there is a possibility that the snow flows from between the wires to the adjacent ground. .

In addition, snowfall fences (fences) that are manufactured according to the site have the advantage of being able to be designed according to the site where they are installed. There is a problem that it takes labor and time for construction, such as the need for rust-proof coating every several years, and maintenance is also expensive after installation.
In addition, once such a snowfall fence is installed, it will block sunlight and ventilation, so if it is installed near a wall with a window, it may interfere with daylighting and ventilation in the room and should not be used. In the summer, it was not preferable in terms of scenery and crime prevention, such as giving residents a sense of pressure and blocking the line of sight to the outside.

  The present invention has been proposed to cope with such various situations, and it is possible to surely prevent the snow falling from the roof from flowing into the adjacent land, and there is little work at the time of construction.

A movable bracket that supports the horizontal fence is detachably attached to at least one of the sides, and the horizontal fence can be fixed at an arbitrary position by supporting both ends of the horizontal fence with the movable bracket. It is characterized by that.

  According to a second aspect of the present invention, in the first aspect, the movable bracket is formed in a right triangle shape, and a locking member is attached to a vertical portion of the movable bracket so as to constitute the support column. When at least one side of the pair of side surface portions is provided with a locking hole that engages with the locking member of the movable bracket in the side surface portion of the column, the movable bracket is attached to the side surface portion of the column. Further, the vertical portion of the movable bracket is in contact with the side surface portion of the support column.

According to a third aspect of the present invention, in the first or second aspect, the horizontal fence is a rhombus or a square pipe, and one lower surface of the rhombus pipe or the square pipe is attached to one side of the pair of side surfaces of the support column. And the tip of the other side of the rhombus or square pipe is in contact with the inside of the side surface on the other side of the column, It is supported between the side portions on one side and the other side of the support column so that the diagonal line is substantially vertical and substantially horizontal.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the support column, the horizontal fence, and the movable bracket are subjected to a surface treatment by hot dip galvanization.

  According to a fifth aspect of the present invention, in any one of the second to fourth aspects of the present invention, the locking member provided in the movable bracket is a detachment that engages with the locking hole after being inserted into the locking hole.

The number of horizontal fences and the installation position can be changed flexibly according to the conditions such as the area of the roof, the amount of snowfall, and the distance to the adjacent land, and the degree of freedom of correspondence is greatly improved. In addition, since the horizontal fence is detachable, for example, in the summer, the horizontal fence can be removed, so there is an advantage that lighting, ventilation, and scenery to the building are not sacrificed.

  In particular, according to the invention described in claim 2, the movable bracket that supports the horizontal fence can be attached to an arbitrary position with respect to the support column, and has a simple structure and is securely fixed to the support column. It becomes possible to install the horizontal fence which comprises a screen in the optimal position according to a condition.

  In particular, according to the third aspect of the present invention, a rhombus or a square pipe is used as the horizontal fence, and the horizontal fence is supported between the side portions of the support so that the diagonal line is substantially vertical and substantially horizontal. Therefore, the longest part of the side fence can be used as a screen part for protection against snow. As a result, the area of the installed horizontal fence can be used as efficiently as the portion in contact with the snow, and the maximum snow prevention effect can be obtained with a small number of horizontal fences.

  In particular, according to the invention described in claim 4, since the surface treatment by hot dip galvanization is applied to the support pillar, the lateral fence, and the movable bracket constituting the snowfall protection fence, the rust prevention treatment such as painting is periodically performed. Since it is not necessary to carry out the operation, the labor required for maintenance can be reduced, the cost can be reduced, and the durability is improved.
