Description

According to the present invention, mortar finishing work such as the lower surface of the balcony downstairs and the outer wall around the sash even in rainy weather during the period until the main pipe is installed in the slab in the piping work, especially in the drain hardware buried in the drainage port of the balcony. The outside of the temporary scaffolding, such as rainwater that falls on the balcony on the top floor under construction and surplus water that is generated when placing concrete, does not flow down to the balcony downstairs through the drain hardware buried in the drainage outlet. Regarding the drainage receiver in the temporary drainage device for the slab drainage port for draining water.

Conventionally, the drainage pipe of the drainage hardware to be buried in the slab drainage port is used to prevent rainwater and surplus water that fall on the top floor balcony under construction from flowing down the drainage hardware to the downstairs balcony. A fixing bracket provided with a drainage receiver to be fitted externally, a support arm to be attached to the inner wall of the drainage receiver, and a tightening screw for height adjustment, and a fixing bracket that is slidable up and down with respect to the fixing bracket. The drainage tool body consists of a support rod that is fixed in an appropriate position by tightening the screws and has a rotatable hook piece that hooks on the drainage receiving brim of the drain hardware at the upper end, and is attached to and detached from the drainage tool body. A temporary drainage device for a drainage port is disclosed, which comprises a flexible hose portion that becomes flexible. It had a jogo-like shape consisting of a receiver lower cylinder that connects the parts. (Patent No. 3325484)

Generally, in order to install the drain hardware at a predetermined position and height of the slab, the upper end surface of the spacer is brought into contact with the lower surface of the drainage receiving brim of the drain hardware by cutting the spacer made of vinyl chloride to a predetermined length. The drainage pipe is fixed in a state of being placed so as to be fitted on the outside, and concrete is cast and buried. However, in the drainage receiver in the conventional temporary drainage device for a drainage port, as shown in FIG. The inner diameter of the upper cylinder of the receiver is larger than the outer diameter of the drainage cylinder of the drain hardware, and the outer diameter is smaller than the inner diameter of the spacer. In addition, there is a problem that the combined size width becomes small, and there may be no suitable drainage receiver depending on the combination of the size of the drain hardware and the spacer used by the consumer.

If the inner diameter of the spacer is smaller than the outer diameter of the ready-made drainage receiver and the drainage receiver cannot be inserted into the spacer, make a notch in the upper cylinder of the receiver with a cutter or the like and stack them to reduce the outer diameter. I inserted it in the spacer and responded to the site.
However, there are problems that water may leak from the cut portion at the time of drainage, the strength is lowered, and the diversion rate of the drainage receiver is lowered by making a cut.

There are many combinations of spacer and drain hardware size combinations by drain hardware manufacturers, and it is disadvantageous to prepare drainage receivers for each of them in terms of complicated management and economy. Therefore, there has been a demand for a drainage receiver of one size that can be widely used.
