Abstract

PROBLEM TO BE SOLVED: To make it possible to attach a clip part without making a hole in a metal plate roof bending the end parts of both side plates of a square metal plate formed in a channel-shape into mutually opposite form, and attaching a sheath pipe to a bolt having passed through both the side plates. SOLUTION: A sandwichedly holding member 5 is formed by bending a rectangular metal plate into a groove shape and erecting side plates 7, 7a on both right and left sides and bending their tip part to form flange parts 8, 8a. A bolt 9 is passed through both the side plates 7, 7a, and a sheath pipe 13 is fitted between the side plates 7, 7a of the bolt 9. When clamping fittings are attached to a roof, a reinforcing material 15 is previously inserted in the clip 2, and the protruding part of the clip 2 for the roof is pushed in between both the side plates 7, 7a of the sandwichedly holding member so far as a cap 4 abuts against the bolt 9 through the sheath pipe 13, and a nut 12 is fastened to press the flange parts 8, 8a against a reinforcing material 15. Thus a part of the clip 2 sticking to a substrate material 1 can be attached to a metal plate roof 3 protruding so far as fixed width without drilling the roof 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener which is suitable for mounting a metal plate roof on a roof which has a hanging portion and which has a predetermined width.

[0002]

2. Description of the Related Art When constructing a roofing material made of a metal plate, three-dimensional suspenders are fixed to a base material in parallel at predetermined intervals, and the flat roof material ends are lifted by the suspenders. Joining and supporting the convex part of a three-dimensional roofing material are performed. FIG. 11 shows an example of the former case, in which a plurality of long channel steel suspensions 2 are attached to a base material 1 in parallel with each other in a state of being extended in the inclination direction of the roof, and on both sides thereof. The end of the roof plate 3 is fixed in a lifted state, and the fixed end of the roof plate 3 and the hanging member 2 are covered with a cap 4.
It is designed to prevent rainwater from entering.

When attaching a snow stopper or a solar cell panel or fixing the upper part of the pillar of the veranda to such a roof, it is necessary to attach the stopper to the roof.
This installation was done by screwing a fastener to the roof with screws and nails and sealing the hammered portion by caulking. However, this method has a problem in that, since holes are made in the roof plate 3, if the coking deteriorates, rain leakage and corrosion occur.

[0004]

DISCLOSURE OF THE INVENTION The present invention provides a fastener which can be attached to a roof of a metal plate having a portion of a suspender fixed to a base material and protruding by a predetermined width without making a hole.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a stopper is formed by bending both sides of a square metal plate in either the front or back direction in the same direction to form a groove shape in which side plates face each other on the left and right sides of a central plate. , Bend the ends of both side plates to face each other,
Bolts were penetrated from one side into both side plates of the sandwiching member serving as a flange portion, and a sheath tube was attached to the outer periphery of the portion between both side plates of the bolt.

[0006]

The stopper is designed so that the gap between the side plates of the groove-shaped holding member can be inserted from the flange portion to the portion of the roof protruding by the suspender, or if the side plate is widened, the flange protrudes from the suspender. Allow insertion from the side. Inserting the sandwiching member from the flange side until the bolt strongly abuts the portion protruding by the roof suspension via the sheath tube with the side plate spacing of the sandwiching member set in this way, When the nut is tightened after the nut is screwed into the tip, the gap between the both side plates is narrowed, so that the protruding portion of the roof is strongly held by the flange portion. By holding the flange and abutting the bolt, the stopper is prevented from moving or rotating. In addition, when tightening the nut, the bolt moves with respect to the roof plate, but since the sheath is attached to the outer periphery, it does not damage the surface of the roof plate and if the length of the sheath pipe is adjusted. It is possible to prevent the protruding portion of the roof suspension from being significantly deformed due to excessive tightening of the nut.

The holding member has a large holding force when the ends of the flange portions are opposed to each other so that the holding members are symmetrical with each other. In addition, the bolts are pierced so that they are parallel to the center plate, and at least one of the bolt insertion holes in the side plate is a stupid hole smaller than the head or nut of the bolt so that the space between both side plates can be easily narrowed. To do. If the bolt is a square root bolt and the bolt insertion hole in the side plate on the head side of the bolt is a square hole, rotation of the bolt can be prevented when tightening the nut. Since the roof suspension is pushed from both sides by the flange portion of the fastener, it is crushed when the suspension has a groove shape as shown in FIG. In such a case, a reinforcing material resistant to compression is inserted inside the suspension.

In the case of attaching a snow stopper or a pillar of a veranda that is erected to the roof with this stopper, one side of the center plate in the front-rear direction is the bent side of the side plate as in Example 2 described later. Bend it to the side opposite to, and make the protruding piece of the bent part stand upright with respect to the center plate, provide a mounting hole in the protruding piece, and in the case of a snow stopper, attach a large stop plate, and attach it to the pillar of the veranda. In that case, a connecting rod with the upper part of the pillar may be attached.

When a solar cell panel along a roof is to be mounted, mounting holes are provided on both sides of the center plate in the front-rear direction as in Example 3 described later, and the holes are connected with bolts. The tool may be inserted and the frame material for supporting the solar cell panel may be fixed.
