Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor drain device, and more particularly to a sheet waterproof floor drain device used when a floor surface is finished by a waterproofing method using a resin sheet.

Conventionally, when the floor surface of a building is finished using the waterproofing method using sheets, in order to install floor drain equipment such as an above-floor cleaning port or drain fitting on the floor surface, the following procedure is generally used. Construction was underway.

First, when placing a floor concrete slab (hereinafter simply referred to as a slab), a drain pipe of an appropriate length to be connected to a floor drain device is installed in advance in the piping sleeve that is installed vertically through the sheet. Stand up perpendicular to the slab surface and install the piping. Here, regarding the drain pipe, the appropriate length refers to the desired finished floor level and the top surface of the floor drain fixture obtained by the uniform mortar and sheet thickness that will be applied to the top surface of the slab in a later process. It is of sufficient length to make it flush. In other words, the upper end of the drain pipe installed perpendicular to the slab surface, where it connects to the floor drain fixture, is at the same level as the bottom end of the floor drain fixture, where it should connect to the drain pipe. It is the length of the position.

Next, attach the sheet holder, which is the main body of the floor drain device, to the drain pipe until the upper surface of the sheet holder brim is flush with the leveled mortar surface to obtain the desired finished floor surface. Connect to.

Then, leveling mortar is applied flush with the upper surface of the sheet receiving collar, and finally, the sheet is stretched to maintain waterproofness on the leveling mortar surface and the sheet receiving collar, and is then stretched using a sheet pusher. Then, push the sheet down and attach the upper part of the required floor drain device, such as the above-floor cleaning port and drain fitting.

By the way, when attaching the floor drain device to the floor according to the procedure explained above, the upper end of the drain pipe is connected to the floor drain device, and the lower end of the floor drain device is connected to the drain pipe. When positioning the drain pipe at the level that should be used as a level, the length of the drain pipe must be measured and cut at the site and placed vertically to the slab surface inside the sleeve. Due to on-site construction errors that occur during measurement, cutting, or piping construction, it is difficult to accurately position the area at the above-mentioned level.
In practice, this is usually difficult and results in drain pipes being too low, too high, or sloping relative to the above-mentioned levels. for that,
The upper part of the floor drain fixture may sink, protrude, or slope relative to the level of the finished floor surface, making it impossible to obtain a smooth finished floor surface after installing the sheet, or the desired finished floor surface may not be obtained. This causes construction defects such as not being constructed to the required level.

In short, this means that the seat support of the floor drain fixture cannot be adjusted in height or horizontally corrected for the desired finished floor level after it is connected to the drain pipe. It is caused by this.

Therefore, in view of the above-mentioned drawbacks, the present invention provides for the adjustment of the height of the seat support and the horizontal correction of the inclination of the floor drain device used when the floor surface is finished by waterproofing method using a resin sheet. It is an object of the present invention to provide a drainage outlet device for a sheet waterproof floor that can obtain a desired smooth finished floor even after connecting a sheet holder to a drain pipe.

Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

C is the slab of any floor of the building, F is
This is a finished floor sheet that is stretched over the leveling mortar M while keeping it waterproof, and P is a drain pipe that is installed inside the sleeve S vertically to the slab surface.

Reference numeral 1 denotes the main body of the drainage outlet device for sheet waterproof floors according to the present invention, in which the lower end has a drain hole formed in a substantially cylindrical shape and having a female thread 2 carved inside for connection with a drain pipe P. A pipe connection part 3 is provided, and an annular flange 4 protrudes outward from the upper end thereof in a so-called mortar shape, and bosses are provided vertically at the same location on the plane at the outer peripheral edge of the flange 4. 5, 5 are provided protrudingly, and a female thread 6 is vertically threaded on the upper surface of the boss 5. In addition, the bosses 5, 5 in this embodiment
There are three locations on the top and bottom.

Reference numeral 7 denotes a seat receiver that is formed in the shape of an annular saucer with an outer diameter substantially the same as the outer diameter of the main body 1, and has a seat receiving surface 8 for receiving the sheet F at the outer peripheral edge of the upper surface. It is a tool, and on the outer periphery,
A small hole 9 is provided vertically in a countersunk shape at a position corresponding to the female thread 6 on the upper surface of the boss 5 of the main body 1 in a plan view. And, on the lower surface between each of the small holes 9 on the circumference of the same radius where the small holes 9 are located,
A boss 10 is provided protrudingly, and a female thread 1 is inserted into the boss 10.
1 is threaded through it in the vertical direction. In addition,
The inner diameter of the seat holder 7 is the same as the inner diameter of the main body 1 and approximately the same diameter as the inner diameter of the drain pipe P, and a female thread 12 is threaded vertically through the inner peripheral edge of the inner diameter. An attachment portion for attaching a seat pusher 13, which will be described later, is formed.

Now, the seat support 7 is installed after the main body 1 is connected to the drain pipe P installed in the sleeve S vertically to the slab surface, in order to obtain the desired finished floor surface. In order to correspond to the same level as the upper surface level of the leveling mortar M to be leveled, a screw member is screwed onto the female thread 11 so that its upper end is lowered from the upper end surface of the sheet receiving surface 8 so that it can be screwed in and out. It is placed above the main body 1 via 14. Then, from the small hole 9, a headed screw member 15 is screwed into the female thread 6 of the main body 1 with its upper end flush with the seat receiving surface 8, and the seat receiving member 7 is It is fixed to the main body 1.

On the other hand, the seat pusher 13 described above includes a cylindrical portion 18 equipped with a female thread 17 on the inside for screwing and receiving a cleaning opening cover 16, which is an upper device for a drain, and a cylindrical portion 18 that protrudes outward from its upper end surface. It is formed of an annular upper flange portion 19 and an annular lower flange portion 20 that protrudes inward from the lower end surface portion. A small hole 2 is made in a countersunk shape at a position corresponding to that on the plane.
1 is vertically penetrated to form attachment to the seat holder. Then, the machine screw 22 presses the seat F stretched between the seat receiving surface 8 of the seat holder 7 and the upper flange 19 of the seat pusher 13.
It is screwed onto the female thread 12 of the seat support 7.

Further, 23 is a curing cover for preventing mortar from entering the upper surface of the main body 1 and into the drain pipe P during the leveling mortar M construction, and is usually made of cylindrical cardboard. It is fitted onto the outside of the main body 1 and the seat holder 7 in a wrap-around manner.

As described in detail above, the seat waterproof floor drain device of the present invention allows the seat holder 7 to be freely screwed in and out after the main body 1 is connected to the drain pipe P.
Since the main body 1 is mounted via the screw member 14 screwed into the main body 1, its height is lower than the level that should be flush with the leveled mortar surface to obtain the desired finished floor surface. This makes it possible to adjust the angle and horizontally correct the inclination.

Therefore, the sheet waterproof floor drain device of the present invention prevents the upper part of the floor drain device from sinking or protruding from the desired finished floor surface level due to construction errors on site. Moreover, even if the drain pipe P is inclined, it is possible to finely adjust the height of each screw member 14 according to the inclination to horizontally correct it. This is effective in providing a finished floor of the desired level.

In addition, in this example, the mortar is
Although a cylindrical curing cover 23 is illustrated as a means for preventing mortar from entering the upper surface and into the drain pipe P, it is not limited to this, and any so-called filling that can prevent mortar from entering may be used. Of course.

Furthermore, although the seat pusher 13 is attached to the seat support 7 through the machine screws 22, a technique for directly attaching the seat pusher 13 by carving female and male threads on the inner and outer peripheries of each may also be considered. Although the upper drain outlet device in this embodiment has a cleaning mouth cover as an example, it is also possible to attach a drain perforation plate depending on the purpose of use.

In short, the sheet waterproof floor drain device of the present invention includes a drain pipe connection portion at the lower end, an annular flange protruding outward from the upper end, and a plurality of female threads on the upper surface of the flange. A plurality of small holes are formed vertically through the outer peripheral edge of the drain outlet device, which is threaded in the vertical direction, at positions corresponding to the female threads in the vertical direction, and each of the small holes A plurality of female screws are threaded vertically through the space between the two, and a substantially circular seat pusher is provided at the inner peripheral edge with a receiving part for receiving the upper device for the drain port. Equipped with a mounting part for attaching the
A seat holder is formed in the shape of a substantially annular saucer and has a seat receiving surface for receiving the sheet at the outer periphery of the upper surface, and the upper end thereof is connected to the female thread of the seat holder. It is placed through a screw member that is lowered from the surface and is screwed so that it can be freely advanced and retracted, and from the small hole, a headed screw member is screwed with its upper end flush with or below the sheet receiving surface.
