Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a snow stopper fitting for attaching a snow stopper member attached to a roof having a roof structure constructed by joining metal plates to the joining portion.

[Conventional technology]

Conventionally, for example, as a mounting bracket for mounting a snow stopper member such as a snow stopper rod or a snow stopper plate on a roof having a structure in which metal plates such as color tin, copper plate and stainless steel plate are joined together, As disclosed in No. 61-7313 and No. 61-11372, left and right metal plate seam parts are formed by a sandwiching part formed at the open end of a metal body that is integrally bent. It is sandwiched from the side and fixed with bolts and nuts, or as disclosed in Japanese Utility Model Laid-Open No. 62-40122, a metal plate seam is formed by a pair of metal fitting bodies formed separately. From the left and right sides,
The structure is such that it is fixed with bolts and nuts.
Further, as disclosed in Japanese Utility Model Publication Nos. 63-20754 and 63-20755, a mounting bracket having a configuration in which an auxiliary member for increasing the clamping force is provided in addition to the pair of bracket bodies is also used. ing.

In addition, when installing a snow stopper on a roof waterproofed by stainless steel, a structure is adopted in which a hole is opened above the seam weld line of the seam and the mounting bracket body is fixed with bolts and nuts. ing.

[Problems to be solved by the device]

However, when the metal fitting body is bent and formed as described above, the number of processing steps increases, the manufacturing cost of the metal fitting body increases, and since the holding area of the holding portion is small, the holding force is weak and the slip load during snow accumulation is small. There was a problem that the mounting bracket could not stand it and could slip out of the fitting or come off. Further, if the holding area of the holding portion is increased in order to increase the holding force of such a mounting bracket, two sets of bolts and nuts must be used for fixing, which increases the cost of parts and requires two fastening bolts. Therefore, there is a problem that the installation work efficiency decreases.

Also, when sandwiching the seam part by a pair of metal fitting bodies formed separately, it is difficult to fasten the metal fitting bodies with one set of bolts and nuts while accurately overlapping them.
When tightening the bolts and nuts, the metal fittings rotate with each other, causing a shift, so the gripping part cannot reliably grip the seam,
There is a problem that it easily comes off. Therefore, there is a problem that two sets of bolts and nuts must be fixed in order to accurately overlap the pair of metal fitting bodies so as not to be displaced from each other.

In addition, when a bolt hole is opened in the upper part of the seam and the mounting bracket body is fixed with bolts and nuts, the seam weld line above the seam weld line is narrow in the stainless steel waterproof method, making positioning of the bolt hole difficult. If the hole shifts upward, there is a risk that it will not be able to withstand the shift load due to snow and may break, and if it shifts downward, the seam welded part may be damaged, causing rain leakage.

That is, the object of the present invention is to solve the above problems,
An object of the present invention is to provide a snow stopper fitting that is easy to process, has a low manufacturing cost, has a high efficiency of installation work, and can be securely attached to a seam.

[Means for Solving the Problems]

The above object of the present invention is to fix a pair of substantially symmetrical plate-like metal fitting bodies, each having a horizontal mounting portion having an L-shaped cross section at the lower end, by bolts and nuts so as to sandwich the roof fitting portion. In the snow stopper mounting metal fitting, the rising base portion of the metal fitting body is formed with a concavo-convex portion that meshes complementarily with each other and that is continuous along the horizontal mounting portion in order to deform the fitting portion according to the concavo-convex shape. This is achieved by a snow retaining fitting, characterized in that engaging means for engaging the upper ends of the fitting main body are provided near the upper end of the fitting main body.
