Description

[Detailed Description of the Invention] (Industrial field of application) The present invention can be easily mounted on an existing thin metal plate stepped roof without any processing such as mounting holes.
The present invention relates to a snow stopping device for a thin metal plate stepped roof that prevents snow accumulated on the roof from being accidentally dropped below the eaves.

(Prior Art) Conventionally, as a snow stopper mounting bracket, for example
As described in Japanese Patent Laid-Open Publication No. 2003-115, a locking portion is formed below one end in the longitudinal direction of a strip-shaped metal fitting main plate, and a rising portion is formed from the other end, and a vertical substrate is formed above the metal fitting main plate where the locking portion is formed. Providing a sandwiching part that opposes the vertical plate at an appropriate interval, and screwing a tightening bolt from either one of the vertical plate and the vertical plate toward the other to make it perpendicular to the vertical plate. A snow retaining rod is inserted into a sandwiching portion formed between the plate and the plate, and the snow retaining rod is tightened with a tightening bolt provided in the sandwiching portion. As in JP-A-43-29730, one end of the strip-shaped sheet metal is bent to form a ladder-shaped support frame whose rear side is perpendicular to the bottom side, and a main body with a vault hole formed in the rear side is formed separately. Suppresses are formed by bending one end to provide a hooking side and forming a long hole near the other end. Then, the hook side is placed on the top side from the back of the rear side of the support frame to make it subordinate, and the vault is inserted from the inner surface of the rear side through the vault hole and the long hole of the suppression and fastened with the wing screw. Is known.

(Problems to be solved by the invention) However, in the above-mentioned conventional technique, in the former case, the snow retaining rod is a vertical substrate to which a simple pressing force or a tightening force of the tightening bolt is applied. Since it is attached by clamping force with a vertical plate or by screwing with a tightening bolt, if the tightening bolt is loosened, the snow retaining rod will be incompletely installed and will function as a snow retaining rod. Not only was there a problem that it was not possible to fulfill the above, but there was no reinforcement structure at the upper end of the snow bar, that is, the horizontal bent plate part, so this was often due to the weight of the snowfall. There is a problem that deformation occurs and the snow stopping effect cannot be sufficiently exerted, and there is a problem that the structure is complicated.

In the latter case, the horizontal plate of the angle-formed snow stop plate (snow clasp) simply contacts the horizontal top edge of the upper end of the support frame at the horizontal bending hook side of the upper end of the suppression plate. The same problem as in the former case because there is no downward bent piece for abutting the tip of the horizontal plate part of the snow stop plate on the refraction hooking side of the suppression plate just by being attached in a contact state. There was a point.

(Means for Solving the Problems) The present invention is intended to solve the above problems, and is a hook shape of a lower roof plate in a step connecting portion connecting roof plates forming a thin metal plate step roof. The upper roof is connected to the lower roof plate while the hook-shaped lower end is engaged with the upper end of the roof to vertically install the first snow stop plate fixing member in a substantially vertical shape on the roof plate. The hook-shaped upper end portion of the horizontal second snow stop plate fixing member arranged along the plate is engaged with the hook-shaped upper end portion of the roof plate on the upper side, and The vertical direction of the snow stop plate formed in a substantially cross section in the direction along the eaves between the upper bent portion of the lower end of the snow stop plate fixing member 2 and the vertical plate portion of the first snow stop plate fixing member. A horizontal plate part having a plate part interposed, and a horizontal plate part of the snow stop plate formed at the upper end of the vertical plate part of the first snow stop plate fixing member; It is characterized in that the first and second snow stop plate fixing members and the snow stop plate are attached with bolts and nuts in a state of being brought into contact with a downward bent piece formed at the tip.

You can prevent it from falling.

(Effect) As described above, according to the present invention, the hook-shaped upper end of the lower roof plate in the step-coupling portion that connects the roof plates forming the thin metal plate stepped roof is hooked. The first snow stop plate fixing member is erected substantially vertically on the roof plate by engaging the lower end portions of the above, and is arranged along the upper roof plate connected to the lower roof plate. The hook-shaped upper end portion of the horizontal second snow stop plate fixing member is engaged with the hook-shaped upper end portion of the upper roof plate, and the horizontal second snow stop plate fixing member The vertical plate portion of the snow stop plate formed in a substantially cross-section in the direction along the eaves is interposed between the upper bent portion at the lower end and the vertical plate portion of the first snow stop plate fixing member, and The horizontal plate portion of the snow stop plate is a horizontal plate portion formed at the upper end of the vertical plate portion of the first snow stop plate fixing member and a downward bent piece portion formed at the tip of the horizontal plate portion. Since the first and second snow stop plate fixing members and the snow stop plate are attached with bolts and nuts in a state of being brought into contact with each other, the snow stop plate and the snow stop plate fixing member are not processed on the roof plate at all. It can be easily installed without applying it, and in particular, the mounting structure of the snow stop plate fixing member and the snow stop plate is a sandwiching type by each vertical plate portion formed on the first and second snow stop plate fixing members. Without stopping, a horizontal plate portion is formed at the upper end of the vertical plate portion of the first snow stopper plate fixing member, and a downward bending piece portion is formed at the tip of the horizontal plate portion, and the snow stopper formed in the substantially letter shape is formed on the horizontal plate portion. Since the horizontal plate part of the plate and the tip end part of the horizontal plate part are integrally attached in a state of being brought into contact with each other, the snow stop plate is not only the vertical plate part but also the horizontal plate part and the horizontal plate part. As a result, the tip edge of the plate is also integrated with the snow stop plate fixing member, The strength of the snow stop plate itself is increased at the same time as the strength of the snow stop plate is remarkably strengthened, and it is possible to prevent the snow stop plate from being easily deformed due to the weight of snowfall, and the structure can be simplified. And so on.
