The waterproof base 5 consists of a floor slab 8 such as ALC supported by the frame of the building, and a waterproof sheet 9 laid on the floor slab 8 . A drainage port 10 is formed in the vicinity of the periphery of the waterproof substrate 5 . Note that the floor slab 8 of the waterproof substrate 5 is not limited to ALC, and any material may be used as long as it serves as a substrate for the mortar 6 to be placed. A drainage basin 1 is placed on the position where the drainage port 10 of the waterproof substrate 5 is formed. The mortar 6 is not cast inside the drainage basin 1, but is cast around the drainage basin 1 to fix the basin body 11 of the drainage basin 1. - 特許庁The mortar 6 is cast so that the height of the horizontal portion 13 of the flange 12 of the trough body 11 and the upper surface are the same. The floor finishing material 7 is a rectangular flat plate, and is a decorative material made of PC, for example. The floor finishing material 7 is adhered to the upper surface of the cured and hardened mortar 6 with a special adhesive (not shown), and laid on the upper surface of the mortar 6 except for the position where the drainage basin 1 is installed. The floor finishing material 7 is not limited to this, and for example, it may be made of natural stone or resin, or may be a ceramic floor finishing material.

As shown in FIGS. 3 to 5, the drainage basin 1 includes a basin body 11 placed on the waterproof substrate 5 and a lid 15 arranged to cover the top of the basin body 11 . The drainage basin 1 is made of metal such as stainless steel, and is formed by bending a thin plate. The cell body 11 is in the shape of a square tube with upper and lower openings. The container body 11 has a lid mounting portion 16 that extends horizontally upward, a vertical portion 17 that extends upward from the outer edge of the lid mounting portion 16, and a flange 12 that extends outward from the upper end of the vertical portion 17. there is The flange 12 has an inner side forming a horizontal portion 13 extending horizontally and an outer side forming an inclined portion 14 inclined downward. The slanted portions 14 of the flange 12 are divided into four by notches formed at the four corners of the cell body 11, and each slanted portion 14 is provided with two elongated through holes 18. . By forming the through hole 18 in the flange 12 in this way, as shown in FIG. It can be wrapped around and the mortar 6 can be cast with good workability.

In addition, the square cylindrical side portion 19 is formed under the lid mounting portion 16 of the cell main body 11, and the side portion 19 is provided with a slit 20 formed by cutting from the lower end to a predetermined position. . Three slits 20 are formed on each of the four sides of the side portion 19 at approximately equal intervals, thereby dividing the lower portion of each side of the side portion 19 into four legs 21 . A bent portion 22 is formed in the intermediate portion of the leg portion 21 divided by the slit 20, and is bent so as to expand downward. The bent portion 22 of each leg portion 21 is formed with a linear hole 23 along the bent portion 22, as shown in FIG. 3(B). The linear hole 23 is formed through the leg portion 21 leaving both side ends. The bent portion 22 is formed by dividing the side portion 19 into the leg portions 21 by the slits 20 and having a lower strength than the other portions by the linear holes 23, so that the bent portion 22 can be easily bent manually without using a special tool. , the angle of the bent portion 22 can be changed.

By changing the angle of the bent portion 22, the height of the cell main body 11 when placed on the waterproof substrate 5 can be changed as shown in FIGS. Since the height of the drainage basin 1 can be changed only by changing the angle of the bent portion 22 at the end, a separate member for height adjustment is not required, and the number of parts can be reduced. , construction can be made easier. In addition, since the bent portions 22 are formed in the respective leg portions 21 divided by the slits 20, the bent portions 22 of the respective leg portions 21 can be made uneven even when the waterproof substrate 5 is uneven. By adjusting them together, unevenness can be absorbed, and the cell body 11 can be placed at a desired height in a stable posture. It should be noted that, even when the basin body 11 of the drainage basin 1 is inclined, for example, when the floor finishing material 7 is provided with a water gradient, the bent portions 22 of the respective leg portions 21 are adjusted to the required inclination. Individual adjustments can be made to provide the required tilt.

In addition, since the slits 20 are formed in the side surface portion 19, the water that has permeated the mortar 6 between the drainage basin 1 and the mortar 6 and around the drainage basin 1 passes through the drainage basin 1 through the slits 20 and the drainage port 10. Therefore, it is possible to prevent the continuation of the state in which water is accumulated inside the mortar 6, and suppress the occurrence of efflorescence.

The lid body 15 includes a flat upper surface portion 24, a pair of side portions 25 formed by bending both side ends of the upper surface portion 24 downward, and the lower ends of the pair of side portions 25 being bent toward each other. a grating having a lower edge 26; The upper surface portion 24 has a plurality of receiving holes 27 for receiving the drainage inside the basin body 11 . An elastic elastomer sheet 28 is attached to the lower surface of the lower end portion 26 . The drainage basin 1 is placed so that the elastomer sheet 28 of the lower end portion 26 of the lid body 15 is in contact with the lid placing portion 16 of the basin body 11 . At this time, the height of the portion of the lid body 15 protruding from the container body 11 is formed to be equal to the thickness of the floor finishing material 7, and the height of the horizontal portion 13 of the flange 12 of the container body 11 is set to the height of the mortar 6. When the height of the upper surface is matched, the upper surface of the lid 15 and the upper surface of the floor finishing material 7 are arranged flush with each other. In addition, the elastomer sheet 28 provided on the lower surface of the lower end portion 26 serves as a non-slip contact portion between the cell body 11 and the lid body 15 and provides a buffer, thereby preventing friction and rattling between the cell body 11 and the lid body 15. can be suppressed.

Then, a step of placing the cell body 11 on the waterproof substrate 5 is carried out. As shown in FIG. 6(A), in the step of setting the container body, the height of the upper surface of the mortar 6 to be placed in the subsequent step is made equal to the height of the horizontal portion 13 of the flange 12 of the container body 11. , the angle of the bent portion 22 of the cell body 11 is adjusted in advance, and the height of the cell body 11 is adjusted.

For example, as shown in FIG. 7, when the basin body 11 is installed at a position where the waterproof sheet 9 of the waterproof substrate 5 is one layer, the mortar 6 can be applied without adjusting the height of the basin body 11. The height dimension of the cell body 11 is designed so that the upper surface and the horizontal portion 13 of the flange 12 of the cell body 11 are at the same height. When the cell body 11 is installed at a position where the waterproof sheet 9 is doubled, the bent portion 22 is bent by applying a load to the lower leg portion 21 of the bent portion 22 . In addition, when the container body 11 is installed at a position where the waterproof sheet 9 is tripled, the bent portion 22 is further bent to adjust the height of the container body 11 . Since the side portion 19 of the cell body 11 is divided into slits 20 from the lower end to a position higher than the bent portion 22, for example, a position where the waterproof sheet 9 is triple and a position where the waterproof sheet 9 is double. Even in the case where the main body 11 is placed across the two positions, the angle of the bent portion 22 can be adjusted for each leg 21, and the main body 11 can be adjusted to the desired height and height. It can be placed in any posture.

Next, as shown in FIG. 6(C), mortar 6 is placed on the waterproof substrate 5 for curing. At this time, the mortar 6 is not poured into the inside of the trough body 11 to make it hollow, and the mortar 6 is poured onto the waterproof substrate 5 including the periphery of the trough body 11.例文帳に追加The mortar 6 is placed to a height equal to the height of the horizontal portion 13 of the flange 12 of the trough body 11, and then cured until it hardens. Then, as shown in FIG. 6(D), an adhesive (not shown) is applied onto the mortar 6, and the floor finishing material 7 is attached. The floor finishing material 7 is laid on the mortar 6 so as not to overlap the trough body 11 by cutting off a portion positioned on the trough body 11.例文帳に追加Since the shape of the trough body 11 is a square cylinder, the floor finishing material 7 can be processed so as not to overlap the trough body 11 by cutting it linearly, and the processing of the floor finishing material 7 can be facilitated. can.

After laying the floor finishing material 7 on the mortar 6, the lid 15 is placed on the upper opening of the cell body 11, and the construction of the floor structure 2 is completed.
