Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a snowfall prevention device that is attached to an upper end of an outer edge of a building such as a building.
[0002]
[Prior art]
In general, in cold districts, snow piled up on the rooftop of a building may be affected by the wind and a snow ridge may be generated on the outer edge (parapet) of the rooftop. In order to prevent such a snowfall, a technique is known in which a snowfall prevention member having a substantially triangular cross section with the inside of the building as an inclined portion is provided on the outer edge of the roof.
[0003]
As such a snowfall prevention device, Japanese Patent No. 2882888 discloses a device in which a plate material is bent into a vertical part and an inclined part to form a substantially inverted V shape as a whole, and is covered with a second support column erected on a bottom plate. A technique is disclosed in which the second support is fixed to the first support that is erected on the holder with bolts and nuts while being screwed to the two support (first conventional technique).
[0004]
Japanese Patent Application Laid-Open No. 10-61132 discloses that a snow ridge prevention member having a substantially triangular cross section is obtained by extrusion molding. In other words, the snow candy prevention member is a hollow section having a substantially triangular cross section. is there. Then, it is disclosed that a snowfall prevention member made of a hollow shape member is fitted and fixed to a holder fixed to the upper end of the outer edge of the building (second prior art).
[0005]
[Problems to be solved by the invention]
However, in the first prior art described above, the snow candy preventing member is formed by bending the plate material, so that the manufacturing cost is high, and when it is bent into an approximately inverted V shape, the bent portion is likely to have wrinkles, and a film is formed. There is a problem that it is difficult to manufacture because it cannot be finished in advance.
[0006]
In the second prior art, there is a problem that the attachment strength is inferior because the snow scum prevention member is merely fitted to the holder.
[0007]
In addition, since the snow candy preventing member is a hollow shape, there is a problem that it is difficult to manufacture a large size because of the size limitation of the extruded shape at the time of manufacture.
[0008]
Further, in the first and second conventional techniques, there is a problem that when a large V-shaped or hollow-shaped member is used as a snowfall prevention member, the weight increases and it is difficult to handle during construction or transportation.
[0009]
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an apparatus for preventing snow scum that is inexpensive to manufacture, can be easily manufactured and installed even in a large size, has excellent mounting strength, and is easy to handle during installation and transportation. And
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 is arranged with a space between a holder fixed to the upper edge of the outer edge of the building and the upper edge of the outer edge of the building, and has a longitudinal section. Is provided with a substantially triangular shape snowfall prevention member, a bolt and a nut, and the snowfall prevention member is composed of a vertical plate provided on the outside of the building, a bottom plate, and an inclined plate provided on the inside of the building. The bottom of the vertical plate is provided with a locking portion protruding toward the inside of the building. One end of the bolt is engaged with the bolt engaging portion provided on the holder, and the bottom plate and the vertical plate are engaged. The other end of the bolt is inserted into the stop and fixed with a nut, the upper end of the inclined plate is fixed to the upper end of the vertical plate, and the lower end of the inclined plate is fixed to the bottom plate.
[0011]
In the first aspect of the present invention, the snow ridge prevention member having a substantially triangular cross section is composed of three plate members, that is, a vertical plate, a bottom plate, and an inclined plate. Therefore, when a bent or hollow shape member is used. In comparison, the manufacturing cost is low. Moreover, even if it is a case where it is set as a large sized snowfall prevention member, it can manufacture at low cost, without receiving size restrictions on manufacture like bending and manufacture of a hollow shape material. In addition, since the snow candy preventing member can be transported and constructed in three main members, the weight can be dispersed and the handling is easy.
[0012]
At the time of construction, the holder is fixed to the upper end of the outer edge of the building, one end of the bolt is engaged with the bolt engaging portion of the holder, and the locking portion provided at the lower end of the vertical plate is overlapped with the bottom plate.
