【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. As shown in FIG. 1 and FIG. 2, the drainage basin body 1 is a container having a substantially rectangular shape in plan view with an upper opening, and a part of the bottom surface, in the embodiment, the longitudinal direction of the bottom surface. A drain port 2 is provided at the end. The bottom surface of the drainage basin body 1 has a gentle slope so as to incline downward toward the drainage port 2 side. A flange piece 7 is provided outward at the opening edge of the upper opening of the drainage basin body 1, and a lid mounting step 8 is provided inside the opening edge. Further, a connecting cylinder portion 6 hangs downward from the drainage port 2. The drainage basin body 1 having such a configuration is entirely formed by press-molding a metal such as stainless steel.

As shown in FIG. 2, the trap device 3 is constructed by providing a water sealing means on the outer container body 5, and in the embodiment shown in the accompanying drawings, the outer container body 5 made of metal such as stainless steel is used. An upward cylinder 9 made of a metal such as stainless steel is projected in the hole of the bottom, and a bell-shaped cap 11 having a downward opening with a plate 10 attached to the upper part thereof is loosely fitted in the upward cylinder 9.

Here, the upper end portion of the outer container body 5 made of metal such as stainless steel is a fitting portion 12 having a large diameter and an L-shaped cross section, and the vertical piece 13 of the fitting portion 12 is drained. It is fitted to the outer peripheral surface side of the connecting tubular portion 6 hung vertically from the drainage port 2 of the box main body 1, and in this state, the connecting tubular portion 6 and the upper end portion of the outer container body 5 are connected to each other. It is integrated by pressing with a press in the radial direction as shown in FIG. Here, in FIG. 3, reference numeral 14 is a press-bonded portion. The crimping portion may be provided over the entire length in the circumferential direction, or may be partially provided in the circumferential direction. In this way, by pressing the metal connecting cylinder 6 and the upper end of the metal outer container 5 in the radial direction of the connecting cylinder 6 by pressing, the drainage port 2 of the drainage basin body 1 This makes it possible to prevent the formation of a recess where water is accumulated in the portion where the trap device 3 is mounted. In the case of such integration, a part of the lateral piece 15 of the fitting portion 12 having an L-shaped cross section is positioned inside the connecting cylinder portion 6, and the drain 10 is placed on the plate 10 from above. When the cap 11 of the lower opening to which is attached is fitted, the outer peripheral end portion of the perforated plate 10 is placed and supported on the lateral piece portion 15 portion. Therefore, a gap is formed between the lower end portion of the cap 11 and the bottom surface portion of the outer container body 5, and a gap is formed between the upper surface portion of the cap 11 and the upward cylinder 9. The upward cylinder 9 is made of metal. To install the upward cylinder 9 by projecting it into the hole at the bottom of the outer container body 5 made of metal, the diameter of the lower outer circumference of the upward cylinder 9 should be reduced. The male threaded portion 16 is provided in the smaller portion of the cylinder, and the lower portion of the upward cylinder 9 is fitted into the hole of the outer container body 5 so that the male threaded portion 16 projects downward and the step above the male screw portion 16 of the upward cylinder is placed in the outer container. The upper surface of the bottom of the body 5 is pressed against the periphery of the hole, and in this state, the lower cylinder 19 made of synthetic resin having the female threaded portion 17 on the inner circumference of the upper end is arranged below the outer container body 5 and the female threaded portion 17 is externally threaded. It is attached by being screwed to the portion 16 and pressing the upper end surface portion 18 of the lower cylinder 19 against the periphery of the hole portion on the lower surface side of the bottom portion of the outer container body 5.

A perforated lid 20 made of metal such as stainless steel is removably placed on the lid mounting step 8 inside the opening edge of the upper opening of the drainage basin body 1. The floor drainage basin 4 having the above-described structure is used, for example, as a drainage basin in a bathroom washing room, and drainage flows into the drainage basin body 1 through the hole 21 provided in the lid 20. , Flows from the drainage basin body 1 through the holes of the perforated plate 10 into the outer container body 5, passes through the gap between the lower end portion of the cap 11 and the bottom surface portion of the outer container body 5 in the outer container body 5, Further, the water is drained from the upward cylinder 9 through a gap between the upper surface of the cap 11 and the upward cylinder 9. In this case, water is always accumulated and sealed up to the upper end of the upward cylinder 9 of the outer container body 5, so that a so-called trap action is performed. Then, the water is drained as described above. The metal connecting cylinder portion 6 and the upper end portion of the metal outer container body 5 are pressure-bonded to each other in the radial direction of the connecting cylinder portion 6 by pressing to be integrated. By doing so, it is possible to prevent a dent that would accumulate water from being generated at the portion where the trap device 3 is attached to the drainage port 2 of the drainage basin body 1, and to prevent water from accumulating on this portion and causing dirt to adhere. Therefore, when the lid 20 is opened and cleaned, cleaning of this portion does not take time and the appearance is improved.

FIG. 4 shows another embodiment of the present invention in which the outer surface of the body of the drainage basin body 1 is recessed. In this way, when the outer surface of the drainage basin body 1 is recessed to form the recessed portion 1a, when it is embedded in concrete during construction, the concrete enters into the recess 1a on the outer surface of the drainage basin body 1 body. This will prevent it from coming out upward, and as a result, it will not be necessary to attach a metal fitting to prevent it from coming off.

[0014]

[Effect of device]

 In the present invention, as described above, the drain container main body and at least the outer container body of the drain trap device are made of metal, and the connecting tubular portion protruding downward is vertically provided at the drain outlet of the drain container main body. Since the upper end of the outer container of the trap device was fitted to the outer peripheral surface side of the connecting cylinder, and the connecting cylinder and the upper end of the outer container were pressed by the press in the radial direction of the connecting cylinder. The drainage port of the drainage basin body can be prevented from having a recess where water is accumulated in the part where the trapping trap device is attached. It is possible to prevent such a phenomenon that water accumulates and stains and molds attach to this area to make it dirty.

Further, by denting the outer surface of the body of the drainage basin body, it is possible to prevent concrete from entering the recessed portion of the outer surface of the body of the drainage basin body and coming out upward when it is embedded in concrete during construction. As a result, it is not necessary to mount a metal fitting on the outer surface of the body of the drainage basin to prevent the metal from coming off as in the conventional case.
