Description

[Detailed description of the invention] (Industrial application field) This invention is a snow cover that can be attached to the roof envelope of Yamato-roof, tiered roof, etc., which can be easily and reliably attached, and has excellent strength. Relating to a locking device.

(Prior art) In general, a roof enclosure for Yamato-buki or tiered roofs has a U-shaped cross section formed by folding back the edge of one side of the plate material for the roof enclosure upwards. The joint folded portion formed by folding the other side edge of the enclosure plate material downward is successively joined. Near the joint on such a roof envelope,
A snow catcher with an L-shaped cross section was attached directly upward in the direction of inclination using a fastener such as a screw.

(Problem that the invention aims to solve) In the case of such conventional snow arresting devices, since they are attached directly to the roof envelope using fasteners such as screws, the watertightness around the fasteners is poor. Not good,
There was a problem in that rainwater entered the roof envelope and corroded the roof envelope. In addition, such snow stoppers are fixed to the roof enclosure using fasteners such as screws, but if there is a large amount of snow on the roof enclosure, the slope direction of the snow may Due to the effect of gravity on the snow catcher, there was a problem that the snow catcher could become detached from the vicinity of the attachment point or become bent.

This invention was made in view of such conventional problems and to solve them, and it is extremely simple.
The object of the present invention is to provide a snow prevention device that can be firmly attached, can be effectively shut off from rain, and has excellent strength.

(Means for Solving the Problems) The gist of the present invention in order to solve the above-mentioned conventional problems and achieve the intended purpose is to Form a folded part consisting of a rising piece, a horizontal piece and a hanging piece which are folded upward and have a substantially U-shaped cross section, and outside of the horizontal piece and hanging piece of the folded part, the edge of the other side of the adjacent plate material is folded downward. a contact piece formed by folding back the
In a snow arresting device that is attached to a roof outer enclosure to which a joined folded part is joined, the folded piece is formed from the lower end of the corresponding contact piece toward the inner side of the folded part, and the folded part is bent. A lower clamping piece is inserted under one side and has a locking protrusion on the top surface of the tip, and a rising connecting piece is hinged to the outer edge of the lower clamping piece, and the upper end of the connecting piece is provided with an upper clamping piece that faces the lower clamping piece, a bolt for pulling in the clamping direction is provided between the upper clamping piece and the lower clamping piece, and a cross-section is formed between the upper surface of the joining folded part and the upper clamping piece. An L-shaped insert fitting is provided, and a locking portion is provided on the lower edge of the insert fitting to be horizontally locked to the lower end of the bolt, and the insert fitting and the upper clamping piece are engaged with each other. The snow stopper device is characterized in that the upper clamping piece is provided with a snow stopper plate fixing portion facing upward in an inclined direction.

(Function) This snow arresting device is provided with a lower clamping piece that is inserted under the folded piece of the joined folded part and has a locking protrusion on the upper surface of the tip part for locking the folded piece. Since the piece and the connecting piece are hinged,
The upper clamping piece and the lower clamping piece of the snow trapping device can be easily clamped between the upper surface of the joined folded part and the bottom of the bent piece, and the snow trapping device is clamped and held using a bolt that can be pulled in the clamping direction. It will be necessary to do so.

In addition, since the lower clamping piece and the upper clamping piece of the snow catcher attached to the joint of the roof envelope are hinged by a connecting piece, the snow catcher installed on the upper clamping piece is If an external force due to snow acts on the plate fixing part, there is a risk that the snow arresting device will come off from the roof envelope, but there is a possibility that the snow stopper device will come off from the roof envelope. Since there is an insert fitting that is engaged with the upper clamping piece and is locked to the lower end of the bolt that pulls in the clamping direction, even if an external force due to snow acts on the snow stopper plate fixing part, Since the external force is dispersed to the metal insert, the snow prevention device does not come off from the roof plate envelope.

It is. By configuring and attaching the snow stopper plate fixing portion 40 separately in this way, the snow stopper device 10 of this embodiment can also be attached to the outer enclosure of a Yamato roof.

(Effect of the invention) The snow prevention device of the invention is configured as described above,
A lower clamping piece is provided which is inserted under the folded piece of the joining folded part and has a locking protrusion on the upper surface of the tip part for locking the folded piece, and also hinges the lower clamping piece and the connecting piece. Therefore, the upper clamping piece and the lower clamping piece can be easily clamped between the upper surface of the joined folded part and the bottom of the bent piece, and the snow catcher can be securely clamped with the bolt that pulls in the clamping direction. It can be easily and quickly installed safely without requiring any special effort, and the amount of work can be reduced. Since the snow prevention device of the present invention is not attached directly to the roof enclosure using fasteners such as screws, it will not damage the roof enclosure board and will not cause corrosion to the roof enclosure. Not at all.

In addition, since the lower clamping piece and the upper clamping piece of the snow catcher attached to the joint of the roof envelope are hinged by a connecting piece, the snow catcher installed on the upper clamping piece is If an external force due to snow acts on the plate fixing part, there is a risk that the snow arresting device will come off from the roof envelope, but there is a possibility that the snow stopper device will come off from the roof envelope. Since there is an insert fitting that is engaged with the upper clamping piece and is locked to the lower end of the bolt that pulls in the clamping direction, even if an external force due to snow acts on the snow stopper plate fixing part, Since the external force is dispersed to the metal insert, the snow prevention device has the effect of not coming off from the roof plate envelope.
