Was not suitable for. In addition, a synthetic resin material changes relatively quickly with age, becomes brittle within a few years and may be damaged, and in addition, the notch may be sharp and dangerous. Furthermore, the drainage fitting consisting of a female threaded cylinder with a flange and a male thread to be screwed onto it uses a flat mesh plate, so it will be clogged immediately by foreign matter such as leaves and cotton dust other than drainage. However, there was a problem that the drainage effect would decrease.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is provided to achieve the object of the invention and to solve the conventional problems. The first aspect of the present invention is that, in a floor drainage fitting, a flanged ring is fitted to an intermediate position in the lengthwise direction of a metal cylindrical body, and a cap is placed on the top of the cylindrical body to form the aforementioned flanged ring. A plurality of oval holes, circular holes or non-circular holes are provided in the upper half of the cylinder at the boundary, and a hook-shaped groove is formed at the lower end of the cylinder for detachable engagement with the floor-side hooking shaft. It consists of A second aspect of the present invention is the floor drain fitting according to the first aspect, wherein the thickness is 0. A stainless steel plate of about 5 to 1.0 mm is rolled to form a cylindrical body, the diameter of the hole is set to about 5 to 10 mm, and a circular cap with a hole covering at least the top of the cylindrical body and a ring with a collar are provided. It is fixed to a cylindrical body by welding or a metal adhesive.

[0005]

[Action]

 The operation based on the above means is as follows. First, insert a cylindrical body into the drain outlet provided on the floor to bring the flange of the flanged ring into close contact with the floor surface, and at the same time, drop the vertical groove of the hook-shaped groove at the bottom of the cylinder into the hook shaft on the floor side, and then Turn the cylinder laterally along the lateral groove so that the cylinder does not slip out toward the floor. A connection pipe and a drain pipe that support the cylindrical body are provided on the floor side. Then, the water accumulated on the surface of the floor flows in through a plurality of holes of the cylindrical body protruding from the floor surface, and is drained along the lower side of the cylindrical body. In this case, if foreign matter other than drainage water is mixed, it will be caught in the hole and will not flow into it, and it will block that hole, but since the cylindrical body with a hole projects from the floor surface, Water flows in from the upper part of the hole. It should be noted that water having a large volume of water and accumulated above the height of the cylindrical body is introduced into and drained from the hole of the cap at the top of the cylindrical body.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 is a metal cylindrical body, 2 is a ring with a collar 21 fitted in an intermediate portion of the cylindrical body, and 3 is a cap put on the top of the cylindrical body 1. The cylindrical body, the collared ring, and the cap are formed of a stainless steel plate having a thickness of 0.5 to 1.0 mm. In the case of the cylindrical body 1, a stainless steel plate having a plate thickness of 1.0 mm is rolled into a diameter of about 40 mm, and several seams of the seam 7 are welded, preferably by spot welding. Fix it. For the collared ring and cap, a stainless steel plate of 0.6 mm is formed by drawing with a press machine. Then, the collar ring 2 and the cap 3 are fitted into the cylindrical body 1 and then fixed to the cylindrical body by spot welding. In this case, a metal adhesive may be used instead of spot welding. Further, by fitting and fixing the collar ring and the cap to the cylindrical body, it is possible to maintain the cylindrical shape without spot welding the joint 7 of the cylindrical body, but spot welding is more preferable. It is usually effective to set the height of the upper half part to about 50 mm and the lower half part to about 40 mm with the collar ring 2 as a boundary, depending on the conditions of the installation location. Reference numeral 4 denotes a plurality of drainage introduction holes formed in the upper half of the cylindrical body with the collared ring 2 as a boundary. The shape of the holes is arbitrary, but an appropriate size is acceptable. Oval holes with a length of 10 mm and a width of 5 mm are oriented vertically, and adjacent holes are arranged alternately in a so-called staggered pattern. It should be noted that the oval hole may be replaced by a circular hole, but in that case, the diameter of the hole can be set within the range of 5 to 10 mm. Furthermore, polygonal holes or other non-circular holes are also possible. Reference numeral 5 denotes a hook-shaped groove provided at the lower end of the cylindrical body 1, which is formed by a vertical groove 51 and a horizontal groove 52. Reference numeral 6 denotes a single or a plurality of drainage inlet holes formed in the cap 3 covering the top of the cylindrical body. In the case of a single hole, a relatively large hole (for example, a diameter of about 15 mm) is allowed. Reference numeral 8 denotes a floor provided with a drainage port 9 and a hole 91 for passing a drainage pipe portion, and the surface is usually waterproofed. Reference numeral 10 is a connection pipe for the drainage pipe section on the floor side, and 11 is a hooking shaft provided on the connection pipe 10 described above. It has a cross shape in plan view.

[0007]

[Specific use example]

 The specific use procedure according to the above embodiment will be described below. First, the cylindrical body 1 is fitted into the drainage port 9 provided in the water-proof floor 8 to bring the flange 21 of the collared ring 2 into close contact with the floor surface, and at the same time, the hook-shaped groove 5 at the lower end of the cylindrical body is formed. Each vertical groove portion 51 is dropped onto each hooking shaft 11 on the floor side, and then it is horizontally rotated along the horizontal groove portion so that the cylindrical body 1 is locked to the shaft 11 so as not to come off. Then, the connecting pipes 10 and 10 'and the drain pipe 10 "are connected to the cylindrical body 1. As a result, the water accumulated on the floor surface is protruded from the floor surface. To the inside and is discharged along the lower part of the cylindrical body 1. In this case, if a foreign substance other than the drainage water is mixed, the foreign substance is caught in the hole 4 and does not flow into the inside, and However, since the cylindrical body 1 with holes protrudes above the surface of the floor 8, water flows in from the upper part of the closed hole. Water accumulated above the height of the upper half of the ring also flows in through the drainage introduction hole 6 of the cap at the top.
