Description

The present invention relates to a drainage drain for a gutter of a building. 2. Description of the Related Art Conventionally, as shown in FIG. 3, when attaching a horizontal drain 32 to a gutter 31 provided at the tip of an eaves of a roof 30, if the gutter 31 is made of a thin metal plate, first, FIG. A screw neck 33 having a length of about 40 mm provided with a male screw is fixed to a required portion of the drop plate 34 by welding at a factory in advance, and the drop plate is flattened at the site. Connected to the gutter face materials 35, 36 by welding, goby or rivet 3
7, 37 ', and furthermore, the drop plate 34 is bent so that the lower surface of the screw neck 33 is in contact with the bottom of the gutter and dropped into a predetermined position, and then a socket having a female thread portion as shown in FIG. The L-shaped horizontal drawing tube 39 to which the 38 is fixed is screwed to finish. What, 40 is a body, 4
1 indicates a decorative cell, and 42 indicates a hard gutter. As described above, in the case of the conventional one, the screw neck 33 is previously inserted into the opening face material 34.
In addition to the necessity of welding, it is necessary to connect the outlet face material 34 to the gutter face material at the site and perform a difficult operation such that the lower surface of the screw neck 33 has to be turned up so as to be the bottom of the gutter. I had to do it. Further, in many cases, an unfavorable force acts on the mounting portion of the screw neck 33 when the falling face member 34 is bent and when the gutter falls into the gutter, which causes a crack in the mounting portion and causes water leakage. Was often seen. SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, that is, the difficulty of work that easily causes water leakage, and to make it possible to perform drain installation work more reliably and more quickly. B. Means for Solving the Problems of the Invention By bending the flange at the part corresponding to the bottom of the gutter in the connection direction of the horizontal drain body, the drain can be connected only by forming an opening in the gutter face material. It is like that. However, the present invention is applicable not only to a horizontal drain but also to a hard drain, and in this case, the flange portion in the connection direction of the drain body is provided at the rising portion of the gutter, and the radial flange portion is provided at the gutter. It shall be mounted so that it contacts the bottom. The operation drain body of the present invention is set in a predetermined position in advance, and the gutter surface material is folded up into a predetermined shape, and then is fitted to the drain position, a hole is formed at the outlet, and the packing is placed on one side of the gutter surface material, or By pressing the holding flange body against both sides, inserting a fastener into the threaded rod fixed to the drain body side and tightening the nut, the radial flange part, the tangential flange part, and both of the flange body of the flange body are tightened. It is configured so that tightening force can be applied to three places of the bent part of the flange part. The fastener is divided into a radial flange portion and a tangential flange portion and a bent portion of both flanges, and both fasteners are inserted into a screw rod fixed to the drain body side, One end of the nut comes into contact with the drain body, and the other end comes into contact with the flange surface of the holding flange body. Therefore, when the nut is tightened, the tightening force effectively acts on the holding flange body. 4 and 5 are drain bodies, FIG. 6 is a packing, FIG. 7 is a holding flange body, FIG. 8 is a radial flange portion fastener, and FIGS. 9 and 10 are tangential flange portions. FIG. 11 shows an assembled state diagram of each member, and FIG. 12 shows a sectional view of an assembled state of the drain body and the gutter. A flange body 2a having a radial flange portion 2 and a tangential flange portion 2 'in the same direction as the tangential direction of the tubular body is fixedly attached to one end of the tubular body 1, and the flange body 2a is fixed to the axial direction of the tubular body 1. And a screw rod 4 in the same direction as above and a screw rod 4 in an oblique direction are attached to the cylindrical body 1. Also, the oblique screw rod 4
The rod body 5 parallel to the flange surface of the tangential flange portion 2 'is fixed to the base side slightly, and the above members are integrated to form the drain body 1a. If the tangential flange portion 2 'is formed by forming a part of the flange body 2a into a ring shape and bending the tangential flange portion 2', the tangential flange portion 2 ' Since a gap 6 can be formed at the root, a closing plate 6a is to be attached. The packing 7 is formed in a shape that matches the cross-sectional shape of the tubular body 1. The holding flange body 8a is formed in the same shape as the flange body 2a, and has a radial flange portion 8, a bent portion 9, and a tangential flange portion 8 '. The screw rod 3 is attached to the radial flange portion fastener 26.
Downward portion 2 having surfaces 20, 20 'on both sides of a substantially trapezoidal body 24 having an insertion hole 25 into the cylindrical body 1.
1, 21 'and a pressing portion 23, 23' which has a pressing surface 22, 22 'which is in contact with the flange surface of the pressing flange body 8a and is substantially parallel to the body 24, and further provided with a rib 24'. A fastening tool 14a for connecting the tangential flange portion 8 'and the bent portion 9 of the holding flange body 8a has a substantially L-shape on one side of the body 10 having the insertion hole 11 for the oblique screw portion 4. One end side is an L-shaped rod-shaped body 12 configured to hit the inner wall of the cylindrical body 1 and the rod-shaped body 5, and the other end side is configured to contact the flange surface of the tangential flange 8 ′. A rod-like body 13 configured to hit the vicinity of the bent portion 9
Respectively. In addition, Fig. 9 is for the left side,
Although the drawing shows the right-hand side fastener, the fasteners of the radial flange part and the tangential flange part fastener may be integrated with each other. The assembly of the above members is the first
This is shown in FIGS. As shown in FIGS. 11 and 12, each surface of the holding flange body 8a and the bent portion 9 are provided.
Is configured to be sufficiently fastened to the drain body 1a by a fastening tool, and is formed on the gutter face member 45 side by cutting out a hole having a predetermined size according to the position of the drain body with sheet metal scissors. Only, and the drain body and the gutter surface material can be contacted very easily. C. Effect of the present invention As described above, the effect of the present invention is that the work of contact between the drain body and the gutter surface material is extremely simplified, and that the holding flange body is sufficiently fastened to the drain body. It has a major feature in that there is no need to worry about water leakage, and combined with these effects, shortening the construction period and improving reliability are achieved.
