Description

[Detailed description of the invention] (a) Purpose of the invention Field of industrial application This invention relates to a fastener for connecting a gutter to a drain body of a building. 2. Related Art As shown in FIG. 5, a plurality of screw rods 21 and 21 are attached to a fixed side of a
The gutter face member 24 is inserted between the drain body 20 and the holding member 26 having a shape shown in FIG. 6 on a ring-shaped holding flange 25, and the nut is tightened. I was trying to tighten it. However,
The presser 26 has a drawback in that the shape thereof is complicated as shown in the figure, so that it takes a long time to manufacture the presser 26, and distortion occurs during welding so that the presser does not hit uniformly. Problems to be solved by the present invention In order to eliminate the above-mentioned drawbacks, each holding point of the holding flange can be tightened with an independent fastener. (B) Means for solving the configuration problem of the invention By making the fastening hardware independent for each fastening screw bar fixed to the drain body side, not only the fastening work is simplified, but also the flange surface is almost uniformly It is designed to be tightened. The body of the clamp is inserted into the screw rod fixed to the drain body side of the present invention, and its lower part is adapted to contact the inner peripheral surface of the drain body, and also to the flange surface of the holding flange. The surface is almost parallel to the fuselage, so when tightening the nut, the fastener does not tilt inward of the drain body,
Therefore, the clamp and the presser flange come into contact with each other on a surface of a certain width, which effectively applies a tightening force to the outer peripheral side of the presser flange. In the embodiment of the present invention, the fastener 8 has a down portion 4 having surfaces 3 and 3 'in contact with the inner wall of the drain body 9 on both sides of the body 1 having an insertion hole 2 into a screw rod 11 provided on the drain body 9 side. , 4 'and a pressing portion 6, having a surface substantially parallel to the main body 1 and surfaces 5, 5' configured to press the flange surface of the pressing flange.
6 'and ribs 7 for reinforcement in the width direction of the body 1.
Is provided. Then, as shown in FIG. 4, the fastener 8 was inserted into the threaded rod 11 and tightened with the nut 15, so that it was sandwiched between the packings 12, 12 'on the flange 10 fixed to the drain body 9. The gutter face member 13 is to be tightened by the holding flange 14.
As described above, since the fastener 8 is inserted into the screw rod 11 and the one surface 3 of the descending portion 4 is in contact with the inner wall of the drain body 9 as described above, even if the nut 15 is tightened, the fastener is used. The holding surface 5 can hold down the holding flange 14 while maintaining a state parallel to the surface of the flange 14. (C) Effect of the present invention As described above, the fasteners of the present invention have independent fasteners.
In addition, since the fastener is inserted into the screw rod on the drain body side and has a surface below the inner wall of the drain body, the fastener does not fall, so that the clamping force is reduced by the holding flange. 14 can be tightened so as to reach the outer peripheral portion. Further, since the fasteners 8 are independent of each other, there is an effect that tightening is easy.
