Description

[Detailed description of the invention] The present invention uses a friction fit between the drainage socket used to connect the main body of the drainage trap and the floor and a flange member having a flange, thereby adjusting the position of the drainage trap with respect to the drainage slope or the floor plate and the mounting hole. This article relates to a drainage trap designed to absorb construction variations in dimensions, etc.

Conventionally, it has been known to treat wastewater from a washing machine, for example, through a trap when using a washing machine pan, or by attaching a trap directly to the floor when the machine is installed directly. ing. First, to briefly explain this with drawings, Fig. 1 is an explanatory diagram schematically showing a drainage structure when a washing machine pan is used, partially in cross section. This is the drainage hose. 2 is the floorboard, 3
is a washing machine pan, which is placed on a floorboard 2 and a washing machine 1 is placed inside. A drain trap mounting hole 3a is formed in the washing machine pan 3, and a drain pipe 4 installed under the floor and a drain trap 5 attached to the drain pipe 4 are installed in advance through a hole 2a in the floor plate 2. The attachment hole 3a of the pan 3 and the drain trap 5 are connected. Also, Figure 2 is an explanatory diagram showing the drainage structure when the washing machine is placed directly on the floor in the same way as in Figure 1, but the same parts as in Figure 1 are designated by the same reference numerals. , and its explanation is omitted, but
In this case, the drain trap 5 is directly attached to the hole 2a of the floorboard 2.

By the way, when draining the washing machine 1, for example, and using the washing machine pan 3 as in the former case, the drain trap 5 is directly attached to the pan 3, so the holes 2a in the floorboard 2 are somewhat rough. Although special precision is not required in terms of shape and position, the installation location of the washing machine 1 is determined depending on the relationship with the pan 3, and it requires a larger space than the washing machine 1 itself. When using a dryer as a set, there was a drawback that the legs of the dryer did not fit into the pan 3 and the pan 3 got in the way. Furthermore, when the washing machine 1 is placed directly on the floorboard 2 as in the latter case, the trap 5 and the drain pipe 4 must be connected before the floorboard is installed, and an inspection hole must also be provided. However, the positioning of the hole 2a in the floor plate 2 requires precision, and if the drain trap 5 is round, a corresponding round hole must be drilled, and a special tool is required.

In view of the above-mentioned drawbacks, the present invention has been developed by making it possible to easily install traps even after the floorboards have been installed, as long as the piping is installed close to the specified location, and the installation holes do not need to be round, making it possible to The purpose of this project is to provide a drainage trap that does not require precision and is extremely easy to install. a flange member having a drain socket fixed to one end thereof, and a flange whose one end side is inserted into a through hole provided in a floor plate and can be fitted to the other end of the drain socket and covers the through hole; It consists of a packing that is arranged at the fitting part of the drainage socket and the flange member to make frictional contact between them, and is used to reduce construction variations such as the drainage slope or the positional dimensions of the floorboard and the through hole between the drainage socket and the flange member. This is accomplished by a friction fit with the flange member and a drainage trap configured to absorb at the flange of the flange member.

Hereinafter, the present invention will be explained in detail with reference to the drawings shown as an embodiment.

FIG. 3 is a vertical cross-sectional view of a main part of the drainage trap according to the present invention attached to a floorboard. Reference numeral 10 is the floorboard, and a through hole 10a for installing the drainage trap is bored in a rectangular shape. Reference numeral 11 denotes a drain pipe arranged in advance at the lower part of the floor plate 10 with an appropriate drainage slope;
1 is a drain trap main body in which an outflow side end 12a is fitted and bonded to an end 11a of a drain pipe 11, and a threaded ring 12c with a female thread formed on the inner peripheral surface is integrally attached to the inflow side end 12b. Fixed with adhesive.
Reference numeral 13 designates a tightening tube having a male screw portion formed on its outer circumferential surface to be screwed into the threaded ring 12c, and has a flange 13a formed thereon and a projection portion 13b formed on its inner wall surface. Reference numeral 14 designates a drainage socket, the lower end of which forms an inward end 14a, and the upper end of which forms an axially parallel end 14b. The lower end 14a of the drain socket 14 is clamped and fixed between the threaded ring 12c and the flange 13a of the clamping pipe 13 via a rubber packing 15 by screwing. Note that the lower end 14a of the drain socket 14 is formed in a circular shape, and the same surface as the upper end 14b parallel to the axial direction is formed in a square shape. hole 10
It has entered inside a. 16 is a flange member;
It consists of a square fitting part 16a that fits into the end 14b of the drain socket 14, and a square flange 16b that extends outward perpendicularly to the opening axis direction and has a width that completely covers the through hole 10a of the floorboard 10. A projection 16c is formed at an inner corner of the fitting portion 16a. Reference numeral 17 denotes a rubber gasket, which is attached to the end 14b of the drain socket 14 and comes into frictional contact with the outer wall surface of the fitting portion 16a of the flange member 16 to maintain a sealed state between the socket 14 and the flange member 16. There is. Reference numeral 18 is a perforated plate having a hole of an appropriate shape, and is placed and locked on the protrusion 13b of the tightening tube 13. 19 is a tube supported by the clamp tube 13.

Therefore, according to the drain trap of the present invention having the above-mentioned configuration, the drain pipe 11 is arranged under the floor in advance, and the drain pipe main body 12 is large enough to fit into the approximately predetermined position after flooring. By forming the through hole 10a for installing the drain trap in a rectangular shape, the drain trap can be easily installed. That is, in this state, the drain trap main body 12 is placed under the floor from the top of the floorboard 10, and the outflow side end 12a of the main body 12 is fitted and glued to the end 11a of the drain pipe 11 installed in advance, and the main body 12 is temporarily attached. Fix it. After that, the drain socket 14 is screwed and fixed to the main body 12 using the tightening pipe 13, and the flange member 16 is pushed into the fixed drain socket 14 from above, so that the socket 14 and the flange member 16 are attached to the gasket 17. Therefore, it is fitted into a predetermined position while making frictional contact. At this time, due to the frictional contact fitting between the two, construction variations in the drainage slope and vertical position dimensions of the drain trap body 12 are absorbed without any problem, and the flange 16b of the flange member 16
can be easily matched to the floor surface. Also, variations in the lateral positional dimensions of the drain trap installation through hole 10a and the drain trap main body 12, that is, the drain socket 14, may occur due to the difference in the flange member 16.
This can be absorbed by covering the through hole 10a with the flange 16b. Thereafter, if necessary, the flange 16b of the flange member 16 is fixed to the floorboard 10 at an appropriate position with screws (not shown), and if necessary, the fitting portion between the drain socket 14 and the flange member 16 is fixed from the opening side (not shown). It penetrates with screws and is fixed to the floorboard 10. Drainage work can be carried out by attaching the perforated plate 18 with the pipe 19 attached by fitting the pipe 19 into the notch groove to the drain trap main body 12 fixed in this manner by supporting it on the protrusion 13b of the tightening pipe 13. Complete. When in use, either insert the drain hose or drain elbow 20 into the pipe 19, or insert the drain socket 16.
What is necessary is to arrange an end portion in the section. Furthermore, when the lid 21 is not in use, by supporting and closing the lid 21 on the protrusion 16c of the flange member 16, the opening is closed and can be made almost flush with the floor surface. In addition, when using the extension hose 22 as a drainage hose, by setting the drainage socket 14 to an appropriate depth in advance, it can be stored as shown by the two-dot chain line when not in use, making it convenient for use. It is.

By the way, in the above-mentioned embodiment, the present invention was explained as a drainage structure, but it is not limited to this and can be used for other liquid drainage, and it is of course not limited to washing drainage. The mounting location of the packing during friction fitting with the member is not limited to the embodiments, and may be any suitable location between the fitting parts, and the packing should be installed intermittently and not over the entire fitting part. The present invention is not limited to the above embodiments.

As described above, according to the drainage trap of the present invention, even if only a drainage pipe is installed in advance and the floor is covered, a hole in a rectangular shape, for example, can be drilled at approximately a predetermined position, and a hole can be inserted through the trap. Since the drain trap body can be attached and fixed, construction work is easy.During the fixing work, the drain socket and flange member are arranged so that they can slide freely due to friction, so there are no dimensional problems during construction. Variations can be easily absorbed, and misalignment of the trap installation through-hole between the drain trap body and the floor can be absorbed by covering the through-hole with the flange of the flange member, so construction work is easy without the need for adjustment work. It is characterized by being extremely simple, and the work of creating through holes can be made extremely easy by making the shape of the drain socket and flange member square, for example, in a shape that is easy to drill. be.
