Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a trap.

[Background of the invention]

Conventionally, a trap has been integrally formed of cast iron or the like, and work for attaching the integrally formed trap to a span or the like has been performed on site. Generally, the trap has an upper part as a receiving part for collecting waste water, and a water sending part connected to a pipe is formed below the receiving part.

Since the size of the water supply section is larger than the width of the receiving section, it is inevitable that a large opening through which the water supply section comes in and out is required to be installed in the span when the water supply section is mounted. By providing the large opening, the strength of the building floor will be weakened, and in order to support the own weight of the trap itself, some mounting means will be required at the mounting location, which will be complicated in terms of process.
Moreover, the positioning of the trap attachment was often slightly deviated.

[Purpose of device]

Therefore, the present invention has been made by paying attention to the problems of the above-mentioned conventional techniques. By solving these problems, the opening provided in the span or the like is minimized, and special support means is provided. It is an object of the present invention to provide a trap that does not require it, simplifies the process, and easily positions the installation location.

[Means for Solving the Problems]

In order to achieve this purpose, the trap according to the present invention is
In a trap in which a part of the trap body is positioned by concrete such as span, the trap body is divided into upper and lower parts, the upper part of which is positioned by concrete, and corresponding flanges are formed on the lower end of the upper part and the upper end of the lower part. However, the flange is characterized by being fastened with a bolt with a waterproof material interposed.

[Action]

With the above-mentioned configuration, unnecessary large openings are not provided in concrete, etc., the strength of the building floor is kept strong, and no special bearing means is required.
In addition, the positioning becomes easy, and the mounting process becomes very easy.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 is a partially sectional front view showing a first embodiment of the present invention, FIG. 2 is a partially cutaway sectional plan view of the same, and FIG. 3 is a partially sectional front view of a second embodiment. Similarly, FIG. 5 is a sectional view showing the third embodiment, and FIG. 5 is a plan view showing the same.

In FIGS. 1 and 2 showing the first embodiment, reference numeral 1 denotes a trap body, particularly a trap body conveniently installed in a machine room or the like. The trap body 1 is connected to an upper part 2 which is a receiving part and a pipe, and is separated into a lower part 3 which is a water feeding part. The upper part 2 and the lower part 3 are mutually connected via a ring 4 at their abutting portions. The flanges 2a and 3a are fastened to the bolt 5. To mount the trap body 1, first, the upper part 2 is positioned and spun concrete A is placed, and then the upper part 2
Is fixed with concrete A, and in this state, the lower part 3 is fixed to the upper part 2.

Further, the upper portion 2 of the trap body 1 has a wider upper surface opening than usual, and the eye plate is intentionally removed. That is, conventionally, in a machine room or the like, a drain groove is formed on the floor surface up to the trap location and is guided to the opening of the perforated plate, which is troublesome in construction. According to the trap body 1 in one embodiment, since the opening of the upper portion 2 is formed to have a wide opening, a pipe for drain or the like is installed and the tip thereof is fixed to the inside of the upper portion 2 so that it is sufficient. Has become.

Next, in FIG. 3 showing the second embodiment, 6 is a trap body, particularly a trap body which is convenient to use for a bathroom. This trap body 6 is also separated into an upper part 7 and a lower part 8, and the upper part 7 and the lower part 8 are fastened with bolts 9 · 9. The formed frame material 10 is also inserted. Further, in the case of the second embodiment, partly because it is for a bathroom, the lower half of the upper part 7 is fixed by the concrete A, and the upper half is matched with the concrete B corresponding to the bottom part of the bathtub. . In addition, 11 has shown the eye plate.

Further, in FIGS. 4 and 5 showing the third embodiment, 12 is a trap body, which is also a special driving type trap body. The trap body 12 is also divided into an upper portion 13 and a lower portion 14, and the upper portion 13 is fixed with concrete. The upper portion 13 of the trap body 12 is formed in a substantially rectangular shape, and in addition to the square-shaped eye plate 15, a separate opening 16 is formed on the upper surface, and a lid body 17 is detachably provided. Also,
The upper portion 13 and the lower portion 14 are fixed by bolts or the like via the packing 18, but from the shape of the upper portion 13, a flange 19 is projected at one end, and a tap hole 20 is bored there. Direct fastening is done.

The bolts for fastening in each embodiment can be replaced with nails or the like.

The trap according to each embodiment is configured as described above. In both cases, the trap body is separated into upper and lower parts, the upper part is fixed with concrete, and the lower part is fixed to the upper part.Therefore, it is not necessary to open a larger opening than necessary in the span etc. The strength is kept strong and the construction is very easy.

[Effect of device]

As described above, according to the trap of the present invention, the strength of the building floor can be maintained, and the mounting process including positioning is very easy.
