By the way, not only the drainage partition material but also the floor material may be installed on the veranda in consideration of waterproofness, anti-slip property and design property. When the floor material is installed together with the drainage partition material, it is preferable to install the floor material along the end of the drainage partition material because no gap is generated between the two.

Here, there are variations in the material, shape, and the like of the floor material, and one of the variations is the height (thickness) of the floor material. Therefore, it may be possible to select a plurality of different heights as the flooring material to be installed on the balcony.

However, since the height of the end of the drainage partition material installed together with the flooring material is constant, if the height of the flooring material corresponds to the height of the drainage partition material, both heights will be the same. If the height of the end portion and the height of the floor material are different, there is a problem that a step is generated at the boundary portion between the two, which affects the cleanability.

Therefore, in view of the above problems, it is an object of the present invention to provide a drainage partition material that can be used for flooring materials having different heights.

In order to solve the above problem, claim 1 is a drainage partition material having a main body portion installed on the floor surface and a wall portion extending vertically upward from the main body portion, and the main body portion is the same as the drainage groove portion. It has a groove edge portion located outside the drainage groove portion in the width direction, and the outer end portion of the groove edge portion has a first height and is inward in the width direction with respect to the outer end portion in the groove edge portion. Is characterized by having a position at a second height different from the first height, and having a cut display portion along the depth direction at the position at the second height.

With this configuration, when the floor material corresponding to the first height is used, the drainage partition material can be used as it is, and when the floor material corresponding to the second height is used, the drainage partition material can be used as it is. If the material is cut along the cut display portion, the end portion of the drainage partition material after cutting has a second height, so that it can correspond to the floor material having the second height.

The second aspect is characterized in that the first height is higher than the second height. As a result, the outer edge of the groove edge portion can be made the highest in the drainage partition material, and the water located on the groove edge portion can be guided to the drainage groove portion.

Claim 3, wherein the cutting display unit is characterized by a groove formed on the upper surface of the groove edge portion along the depth direction. Thereby, if the groove edge portion is cut along the groove, an end portion having a second height can be formed.

A fourth aspect of the present invention is characterized in that the groove edge portion has a slope at a boundary with the drainage groove portion, and the groove edge portion is higher than the drainage groove portion. As a result, the slope of the groove edge can be used as an outer bank of the drainage groove.

A fifth aspect of the present invention is that the drainage partition material has a cross-sectional shape in the width direction symmetrical about the wall portion, and has the drainage groove portion and the groove edge portion on both sides in the width direction across the wall portion. And. As a result, even if the drainage partition material is rotated 180 degrees in the depth direction, the same shape is obtained, so that the drainage partition material can be used as it is even if the direction in the depth direction changes.

According to the drainage partition material of the present invention, it is possible to cope with flooring materials having different heights.

Hereinafter, an embodiment of the drainage partition material 10 that embodies the present invention will be described with reference to FIGS. 1 to 6. There are two types of flooring materials installed on the balcony 30 together with the drainage partitioning material 10 having different heights, specifically, a flooring material A having a height of 2.5 mm and a flooring material B having a height of 2 mm. The following description will be given, but the heights of the flooring materials A and B described here are merely examples, and are not limited to these heights. Further, the drainage partition member 10 is also shown with specific numerical values so that the size and the like can be easily imagined, but the numerical values are merely examples and are not limited.

Configuration of Drainage Partition Material 10 FIG. 1 is a perspective view of the drainage partition material 10 of the present embodiment, and FIG. 2 is a cross-sectional view of the drainage partition material 10 in the width direction. In the drainage partition material 10, the width (left and right), depth, and height (up and down) refer to the directions shown in FIGS. 1 and 2. The inner side in the width direction means the left and right center side in FIG. 2, and the outer side in the width direction means the left and right outer side in FIG.

As shown in FIG. 2, the drainage partition member 10 has a substantially thin plate-shaped main body portion 11 and a wall portion 12 extending upward from the center in the width direction on the upper surface of the main body portion 11, and as a whole, a substantially inverted T. It is in the shape of a letter.

Further, as shown in the perspective view of FIG. 1, the drainage partition member 10 is integrally molded in which a substantially inverted T-shape shown as a cross-sectional view in FIG. 2 is continuously formed in the depth direction. Therefore, the shape of the drainage partition member 10 based on FIG. 2 in the following description is continuously formed in the depth direction of the drainage partition member 10 without any particular explanation.

The specific size of the drainage partition member 10 is shown. The total width of the drainage partition member 10, that is, the length in the width direction of the main body shown in FIG. 2 is 100 mm, and the total height of the drainage partition member 10, that is, shown in FIG. The height to the top of the wall portion 12 (referring to the height from the bottom surface 13; the same applies hereinafter) is 25 mm.

As shown in FIG. 2, the drainage partition member 10 has a symmetrical shape in the width direction with the wall portion 12 as the center, and the main body portion 11 has the drainage groove portion 14 and the groove edge portion 15 in this order from the side closer to the wall portion 12. It is formed on both sides of the portion 12 in the width direction. Further, although the bottom surface 13 of the main body 11 is flat, microscopically, fine arcuate irregularities are formed in the width direction. Since the drainage partition member 10 has a symmetrical shape in the width direction with the wall portion 12 in between in FIG. 2, the explanation of the drainage groove portion 14 and the groove edge portion 15 of the main body portion 11 is given to only one of the left and right sides in FIG. Will be described, and the other description will be omitted.

The drainage groove portion 14 serves as a flow path for flowing water located on the upper surface of the drainage partition member 10 along the depth direction of the drainage partition member 10, and has three protrusions on the upper surface thereof substantially evenly in the width direction. Article 16 is formed. By forming these three ridges 16 in parallel along the depth direction of the drainage partition member 10, the region of the drainage groove portion 14 is divided into four in the width direction, and the width of each flow path in the drainage groove portion 14 is narrowed. To prevent the meandering of water.

The groove edge portion 15 is continuously formed in the drainage groove portion 14 on the outer side in the width direction (the side away from the wall portion 12) of the drainage groove portion 14, and the upper surface thereof is formed higher than the drainage groove portion 14.
FIG. 3 shows an enlarged cross-sectional view of the drainage partition member 10 shown in FIG. 2 in the width direction centering on the groove edge portion 15, but for convenience of explanation, the hatching (parallel diagonal line) shown in FIG. 2 is shown. Is omitted.

As shown in FIG. 3, a slope 17 is formed on the upper surface of the groove edge portion 15 so as to be in contact with the drainage groove portion 14 and increase in height toward the outside in the width direction. Further, the upper surface of the groove edge portion 15 is a gentle slope whose height gradually increases from the upper end of the slope 17 toward the outside in the width direction, and the upper surface of the outermost end portion 18 located on the outermost side becomes the highest. ing. The height (first height) of the outer end portion 18 is set according to the height of the floor material A and is 2.5 mm. The height of the upper end of the slope 17 of the groove edge 15 is 1.8 mm.

At a position where the height of the substantially central portion of the groove edge portion 15 in the width direction, specifically, the upper surface of the groove edge portion 15 is 2 mm (second height), a V groove is formed on the upper surface of the groove edge portion 15. 19 is formed. The V-groove 19 is formed orthogonal to the width direction, and the width of the upper surface opening is 0.5 mm and the depth is 0.25 mm. The center of the upper surface opening of the V groove 19 in the width direction is a position where the height of the upper surface of the groove edge portion 15 is 2 mm when the V groove 19 is not formed.

Therefore, the position where the upper surface of the groove edge portion 15 has a height of 2 mm (second height) is not only when the upper surface height of the groove edge portion 15 is actually 2 mm, but also when the groove edge portion 15 has a V. It is a concept including a position where the upper surface of the groove edge portion 15 has a height of 2 mm when the groove 19 is not formed (the V groove 19 is filled). The V-groove 19 functions as a cutting display portion, and when the groove edge portion 15 is cut along the V-groove 19 in the depth direction of the drainage partition member 10, the V-groove 19 of the groove edge portion 15 The outer side in the width direction can be cut and separated, and the height of the end portion 20 (cut end portion 20) of the drainage partition member 10 after cutting is 2 mm.

As shown in FIG. 2, the cross-sectional shape of the wall portion 12 is symmetrical. The rising portion of the wall portion 12 from the main body portion 11 has a straight cross-sectional shape in which the width gradually narrows toward the upper side, the upper portion of the wall portion 12 rises upward with a constant width, and the top portion following this is the lower side thereof. It is formed in a rhombus shape with a cross section larger than that of the portion. The wall portion 12 stands up on the floor surface of the balcony 30 in the space below the partition wall W to prevent the water used in the balcony 30 from flowing to the balcony 30 of the adjacent house.

Manufacture of Drainage Partition Material 10 The drainage partition material 10 is formed by extrusion molding using a thermoplastic elastomer as a material. Examples of the thermoplastic elastomer that can be used as the drainage partition material 10 include polyvinyl chloride, polystyrene, polyolefin, polyurethane, polyester and the like.

Further, since the drainage partition material 10 is continuously formed by extrusion molding, the length of the drainage partition material 10 in the depth direction is not particularly limited, and the drainage partition material 10 is cut to a length suitable for transportation, storage, etc. in the process of extrusion molding. Then, it may be cut to a required length at the construction site (veranda 30 where the drainage partition material 10 is installed).

Method of Installing the Drainage Partition Material 10 on the Veranda 30 A method of installing the drainage partition material 10 of the present embodiment on the balcony 30 of an apartment house will be described. Since there are two types of flooring materials used having different heights (flooring material A having a height of 2.5 mm and flooring material B having a height of 2 mm), they will be described individually below.

When installing the drainage partition material 10 together with the floor material A having a height of 2.5 mm on the balcony 30 First, the drainage partition material 10 is cut to a length corresponding to the protruding width of the balcony 30. Specifically, the length of the drainage partition member 10 in the depth direction is cut to the length from the wall on the room side of the balcony 30 to the front of the gutter on the handrail side of the balcony 30. Further, the floor material A is also cut according to the width of the veranda 30 as needed.

Next, an adhesive is applied on the floor surface (base) of the balcony 30 on which the drainage partition material 10 and the floor material A are installed, and the drainage partition material 10 is placed in the space below the partition wall W which is the boundary with the adjacent dwelling. Stick it on the floor of the balcony 30. The adhesive to be used may be appropriately selected according to the material of the floor surface of the balcony 30, the material of the drainage partition material 10, and the like.

Subsequently, the edge of the floor material A is cut while the floor material A is aligned with the outer end 18 of the drain partition material 10, and the positions of the outer end 18 of the drain partition 10 and the edge of the floor material A are aligned. At the same time, the floor material A is attached to the floor surface of the veranda 30.

As a result, as shown in FIGS. 4 and 5, the drainage partition material 10 and the floor material A are installed on the balcony 30 with their edges aligned. Further, since the height of the outer end portion 18 of the drainage partition material 10 and the height of the floor material A are the same (2.5 mm), the heights of both are the same at the boundary portion between the drainage partition material 10 and the floor material A. Become.

Although the method of installing the drainage partition material 10 and the floor material A has been described for one house, the drainage partition material 10 is arranged between the balconies 30 of the adjacent houses, so to speak, shared by the balconies 30 of the adjacent houses. Therefore, the floor material A is installed on the other balcony 30 in the same manner.

Further, the method of constructing the drainage partition material 10 has been described first as the construction order of the drainage partition material 10 and the floor material A, but the present invention is not limited to this, and the drainage partition material 10 may be installed after the floor material A is installed. Yes, the order of construction of the drainage partition material 10 and the floor material A is not limited.

When installing the drainage partition material 10 together with the floor material B having a height of 2 mm When using the floor material B having a height of 2 mm, the drainage partition material 10 is cut to a length that matches the protruding width of the balcony 30. Later, the groove edge portions 15 on both sides of the drainage partition member 10 are cut along the V groove 19. Then, the height of the cut end portion 20 of the drainage partition member 10 after cutting becomes 2 mm.

An adhesive is applied to the floor surface of the balcony 30 by applying the drainage partition material 10 to the floor surface of the balcony 30 by the same procedure as described above, and the drainage partition material 10 is attached to the floor surface of the balcony 30 in the space below the partition wall W.
Further, the edge of the floor material B is cut while the floor material B is aligned with the cut end portion 20 of the drainage partition material 10, so that the positions of the cut end portion 20 of the drainage partition material 10 and the edge of the floor material B are aligned. , The floor material B is attached to the floor surface of the veranda 30. The drainage partition material 10 is narrowed by the amount cut along the V groove 19, and the floor material B used is increased by that amount.

As a result, as shown in FIG. 6, the drainage partition material 10 and the floor material B are installed on the balcony 30, and the height of the cut end portion 20 of the drainage partition material 10 and the height of the floor material B are the same (2 mm). Therefore, the heights of both sides are the same at the boundary. Further, the same floor material B is installed on the other adjacent veranda 30.

Further, the method of constructing the drainage partition material 10 as the construction order of the drainage partition material 10 and the floor material B has been described first, but the method is not limited to this as in the case of the floor material A, and the drainage partition material is installed after the floor material B is installed. In some cases, 10 is installed, and the order of construction of the drainage partition material 10 and the floor material B is not limited.

Up to now, an example in which the floor material A having a height of 2.5 mm is installed on the adjacent veranda 30 or the floor material B having a height of 2 mm is installed on the adjacent veranda 30 has been described, but they are adjacent to each other. Of course, it is also possible to install a floor material A having a height of 2.5 mm on one of the balconies 30 and a floor material B having a height of 2 mm on the other veranda 30. In such a case, of the drainage partition material 10, only the groove edge portion 15 located on the veranda 30 side where the floor material B having a height of 2 mm is installed may be cut along the V groove 19.

According to the drainage partition material 10 of the above embodiment, the following effects can be obtained.

Therefore, when the floor material A having the same height (2.5 mm) as the height of the outer end portion 18 is installed on the balcony 30, the drainage partition material 10 can be used as it is, and the low (2 mm) floor material B is used. If the groove edge portion 15 of the drainage partition member 10 is cut along the V groove 19, the height of the cut end portion 20 can be made to correspond to the low floor material B. Therefore, the drainage partition material 10 can be aligned with the floor materials A and B having different heights, and the cleanability of the boundary portion is improved.

(2) The drainage partition member 10 has V-grooves 19 formed at groove edge portions 15 on both sides in the width direction sandwiching the wall portion 12. Therefore, it corresponds not only to the case where the floor materials used in the adjacent houses are both low (2 mm) floor material B, but also to the case where the heights of the floor materials used are different from each other (floor material A, floor material B). be able to. That is, even when a flooring material A having a height of 2.5 mm is installed in one dwelling and a flooring material B having a height of 2 mm is installed in the other adjacent dwelling, the other dwelling side of the drainage partition material 10 is installed. Only the groove edge portion 15 located at 1 may be cut along the V groove 19.

(3) In the above embodiment, the V groove 19 is formed as a cutting display portion. Therefore, the tip of the cutting tool may be inserted into the V-groove 19 to cut the groove edge portion 15 in the depth direction along the V-groove 19, and the cutting operation of the groove edge portion 15 becomes easy.

(4) In the drainage partition member 10 of the above embodiment, a groove edge portion 15 is continuously formed on the drainage groove portion 14 on the outer side in the width direction of the drainage groove portion 14, and the upper surface of the groove edge portion 15 is a slope 17. The upper surface of the outer end portion 18 is the highest as a gentle slope in which the height gradually increases from the upper end toward the outside in the width direction. Therefore, the water located on the upper surface of the groove edge portion 15 can flow into the drainage groove portion 14 by this gentle slope and can be drained through the drainage groove portion 14.

(5) The drainage partition member 10 of the above embodiment has a slope 17 whose groove edge portion 15 is higher than that of the drainage groove portion 14. Therefore, the slope 17 functions as an outer bank of the drainage groove portion 14, and drainage in the drainage groove portion 14 becomes possible.

(6) The drainage partition member 10 of the above embodiment has a cross-sectional shape in the width direction symmetrical about the wall portion 12, and has drainage groove portions 14 and groove edge portions 15 on both sides in the width direction with the wall portion 12 interposed therebetween. .. Therefore, even if the drainage partition material 10 is rotated 180 degrees in the depth direction, the shape is the same, and the drainage partition material 10 can be used as it is even if the direction in the depth direction is different. You don't have to worry about the orientation.

The above embodiment may be changed as follows.
○ In the above embodiment, the drainage partition material 10 corresponding to the floor material A and the floor material B having two different heights has been described, but the height of the floor material and the respective sizes described for the drainage partition material 10 are included in this.

○ In the above embodiment, the groove edge portion 15 has a gentle slope whose height gradually increases toward the outside in the width direction, but the present invention is not limited to this. For example, as shown in FIG. 7A, the groove edge portion 15 extends outward in the width direction from the upper end portion of the slope 17 which is the boundary with the drainage groove portion 14 at a constant height (2 mm) and sandwiches the step 21. The groove edge portion 15 may be further extended outward in the width direction to reach the outer end portion 18 while maintaining a constant height (2.5 mm). In this drainage partition material 10, the lower end portion of the step 21 serves as a cut display portion. Therefore, if the groove edge portion 15 is cut along the lower end of the step 21, the height of the cut end portion 20 becomes 2 mm, which is a low floor material. It can be used in combination with B.

Further, for example, as shown in FIG. 7B, the upper surface of the groove edge portion 15 may be a gentle slope that gradually becomes lower toward the outside in the width direction. In this case, in the above embodiment, the position where the V groove 19 (cutting display portion) is located has a height of 2.5 mm, and the height of the outer end portion 18 is 2 mm.

○ In the above embodiment, the V-groove 19 is used as the cutting display unit, but the cutting display unit is not limited to the V-groove 19 of the above-described embodiment.
