Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain for a corner which is attached to a corner of a building such as a rooftop or a balcony and discharges rainwater or the like to a discharge pipe.

[0002]

2. Description of the Related Art Conventionally, drainage of rainwater on a rooftop or a balcony of a building is made to flow from a corner drain such as a rooftop or a balcony to a drain pipe.
In this conventional corner drain, as shown in FIG. 6, the drain main body 1 has a wall surface portion 4 having an outlet 3 formed on one side of the dish-shaped bottom portion 2, and the drain main body 1 has a substantially L-shaped shape. A perforated plate 5 is fitted, and a substantially L-shaped anchor 6 protruding from the bottom of the drain main body 1 is protruded, and the anchor 6 is attached to a reinforcing bar 8 buried in the concrete 7 of the installation portion of the drain main body 1. A structure was adopted in which the wire 6 was bound and fixed by a wire 9.

[0003]

However, in the above-mentioned conventional drain for corners, when the drain body is constructed, first, the anchor 6 is positioned on the reinforcing bar 8 and the work of tying it with the line 9 is troublesome. There was a problem with poor efficiency.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a corner drain which can easily fix a drain body to a reinforcing bar without having to bind with a wire or the like.

[0005]

A corner drain according to the present invention comprises a substantially L-shaped drain body having a substantially vertical wall surface having an outlet on one side of a substantially dish-shaped bottom, and a drain body having the same shape. And a perforated plate body having a bottom perforated portion facing the substantially dish-shaped bottom portion and a wall perforated portion facing the wall portion,
A projecting ridge is formed substantially perpendicularly to the bottom of the drain body, and a holding portion that engages with a reinforcing bar buried in the portion to be installed is cut out in the projecting ridge.

[0006]

In the corner drain according to the present invention, the drain main body is easily positioned and held by engaging the ridge holding portion projecting from the bottom of the drain main body with the reinforcing bar, so that the corner main body can be held at the installation position. The workability of the drain body is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a corner drain according to the present invention will be described below with reference to the drawings.

In FIG. 1 to FIG. 3, reference numeral 11 denotes a drain body, which is formed of a substantially dish-shaped bottom portion 12 and a substantially vertical wall surface portion 13 on one side of the bottom portion 12 in a substantially L-shape made of synthetic resin such as PVC. It is molded in. At the center of the wall portion 13, a cylindrical outlet 14 protruding outward is opened.

The inner surface of the bottom portion 12 of the drain main body 11 is inclined downward at a gentle slope toward one side. Further, the inner surface of the bottom portion 12 of the drain body 11 and the lower end of the outlet 14 are substantially flush with each other.

A receiving base 15 is formed on the front side of the upper surface of the drain body 11, and a stopping base 16 is formed on the rear side of the upper surface opposite to the receiving base 15. Further, the wall portion
In the vicinity of the upper part of 13, an engaging portion 17 is formed to protrude. Also, on both sides of the lower surface of the bottom portion 12 of the drain body 11, a ridge 18 serving also as a reinforcing rib is formed in parallel, and the ridge 18 is opened at a lower edge and held in a direction inclined toward one side. Part 19,
19 are notched at intervals.

Next, reference numeral 20 denotes a perforated body fitted to the drain body 11, and the perforated body 20 includes a bottom perforated portion 21 and this bottom perforated portion.
21 and a substantially vertical wall portion 22 provided substantially vertically from one side.
It is molded in a letter shape from a synthetic resin such as PVC. The bottom of the bottom plate 21 of the plate 20 is provided with the pedestal portion.
An engagement protrusion 23 is formed to engage with the front end 15, and the front end is installed on the stop base 16 and is fixed by a screw 25 screwed into a screw hole 24. The upper end of the wall plate portion 22 of the plate 20 is supported by the engaging portion 17.

The bottom plate 21 and the wall plate of the plate 20 are provided.
22 has an elongated slit 27 formed therein.

Next, the operation of the above embodiment of the present invention will be described.

The holding body 19 formed on the ridge 18 protruding from the bottom 12 of the drain body 11 is inserted into and engaged with, for example, a reinforcing bar 28 buried in the corner of a roof or a balcony, so that the drain body 11 The movement in the direction is regulated and held at a predetermined position. In this state, a drain pipe is connected to the outlet 14 to connect the upper edge 26 of the bottom plate 12 of the drain body 11 and the inner edge of the wall 13.
Pour concrete so that 29 is almost the same plane.

In the above embodiment, the holding portions 19, 19 formed on the ridges 18 of the drain main body 11 are formed in parallel with inclined cutouts toward one side, as shown in FIG. One of the holding portions may be a holding portion 19a having a shape cut out in a concave vertical shape. Further, as shown in FIG.
9 and 19 are holding portions 19b and 19c having shapes inclined in opposite directions to each other.
It can also be.

[0016]

According to the present invention, the drain main body 11 is positioned by engaging and holding the holding portion of the ridge projecting from the bottom of the L-shaped drain main body with the reinforcing bar buried in the installation portion. The work is held, and the work of fixing it by tying it with a wire line is not required, so that the construction is easy, the labor can be saved, and the workability can be improved.
