Description

  The present invention relates to a drainage part covering member, and more particularly to a drainage part covering member configured to be effectively applicable to a portion having unevenness due to a water gradient.

For example, in a veranda or the like, there is a drain which is a drainage part for draining rainwater or the like.
In order to efficiently drain the water present on the veranda floor from such a drain, a gradient toward the drain is formed around the drain.
On the other hand, a balcony mat or the like is often applied to the veranda floor, and in such a case, there is a problem that the land becomes inland due to the gradient toward the drain.
Techniques for eliminating such unevenness have been proposed (see, for example, Patent Document 1 to Patent Document 3).

Patent Document 1 discloses a cover member that covers a drainage portion such as a veranda.
The cover member is a member that is self-supported on the drain, and includes a flat plate portion that covers the drain upper portion and a plurality of legs that stand on the drainage guide portion.
The legs are erected vertically with respect to the flat plate portion, but their length (distance from the flat plate portion to the free end) varies depending on the inclination of the drainage guiding portion, and thus By changing the length, the drainage gradient of the drainage guidance part is absorbed and the uneven state is eliminated.
Similarly, Patent Literature 2 and Patent Literature 3 also eliminate unevenness around the drain by forming leg portions with different lengths (distance from the flat plate portion to the free end) with respect to the flat plate portion covering the drain. It is configured to

Japanese Patent No. 5297718 Japanese Patent No. 3330317 Japanese Patent No. 4475905

However, according to the techniques of Patent Literature 1 to Patent Literature 3, since the upper portion of the drain is covered with one cover member, there is a problem that it is inconvenient when performing operations such as inspection and cleaning of the drain.
Also, it was difficult to cope with the water gradient size around the drain.
Furthermore, it was not supposed to lay a floor mat. That is, it was not supposed to support the floor mat laid at the upper part of the drain.

An object of the present invention is to solve the above-described problems, and provide a drainage covering member that can eliminate unevenness due to a water gradient and can easily perform operations such as drain inspection and cleaning. There is.
Another object of the present invention is to provide a drainage covering member that can flexibly cope with the water gradient size around the drain.

  According to the drainage portion covering member according to claim 1, the above-mentioned problem is a drainage portion covering member for covering the drain upper portion, and the peripheral portion of the drain is a first slope that is a downward slope toward the drain And a second inclined portion that is formed at a position facing the first inclined portion with respect to the drain and is a downward inclined toward the drain, and the drain is defined as the bottom with respect to the floor surface The drainage portion covering member is formed in a concave shape, and a frame member that covers the peripheral portion of the drain, and an upper surface member that is configured to be detachable from the frame member and covers the upper portion of the drain. The frame member is disposed on the first inclined member side on the first inclined portion side and on the second inclined portion side with respect to the arrangement position of the drain. A second outer peripheral member and An inspection is formed, and the joint between the first outer peripheral member and the second outer peripheral member is disposed above the drain side, and the upper surface member is detachably fitted above the drain of the joint. An opening is formed, and from the drain side end portion of the first outer peripheral member, a first outer peripheral leg portion depending on the drain is formed, and the drain side end of the second outer peripheral member is formed. A second outer peripheral leg portion that hangs down toward the drain is formed from the portion, and the first outer peripheral leg portion and the second outer peripheral leg portion are different in height from the floor surface of the first inclined portion. And the length of the second inclined portion is set to match the height difference from the floor surface, and the first outer peripheral leg portion is installed at the drain side end portion of the first inclined portion, The second outer peripheral leg portion is in front of the second inclined portion. Is installed in the drain-side end portion, it is solved by relaxing the height difference between the peripheral portion and the floor surface of the drain.

Thus, the drainage part covering member according to the present invention is configured by being divided into a frame member and an upper surface member, and the frame member is further divided into a first outer peripheral member and a second outer peripheral member. Divided configuration.
The first outer peripheral member and the second outer peripheral member are respectively configured with a first outer peripheral leg portion and a second outer peripheral leg portion, and thereby, a descending inclination height difference around the drain (a difference in height from the floor surface). Can be relaxed (compensated).
In other words, the drain upper portion formed at a position descending from the floor surface can be brought close to the floor surface height, and the upper portion of the drain can be made flat with the floor surface or nearly flat.
In addition, the shape close | similar to flat points out the shape of the grade which an unnatural inclination and a recessed part are not formed with respect to a floor surface, when laying a floor mat on a floor surface.
Since it is comprised in this way, when laying a floor mat, there is no inclination and a level | step difference, and while workability | operativity improves, it is advantageous also in designability and functionality.
At this time, the frame member is divided into the first outer peripheral member and the second outer peripheral member, so that the first inclined portion and the second inclined portion have different inclinations (height difference), By changing the height of the outer peripheral leg portion and the second outer peripheral leg portion, it is possible to flexibly cope with the change.
In addition, an inspection opening (above the drain, preferably directly above) is formed at a joint portion (above the drain side) between the first outer circumferential member and the second outer circumferential member. An upper surface member is detachably disposed on the part.
Therefore, it is usually possible to eliminate the unevenness around the drain and to cover the portion directly above the drain by arranging the upper surface member in the inspection opening. This facilitates the inspection work.

  At this time, as described in claim 2, the drain side of the first outer peripheral member is notched to form a first outer peripheral notch portion, and the drain side of the second outer peripheral member is notched. Accordingly, a second notch is formed, and the first outer circumferential member and the second outer circumferential member are aligned at the portion where the first outer circumferential notch and the second outer circumferential notch are formed. When the inspection opening is formed by the first outer periphery notch and the second outer periphery notch, it is preferable because the size can be adjusted easily.

Further, at this time, as a specific configuration, as described in claim 3, the first outer peripheral leg portion and the second outer peripheral leg portion are a part of the periphery of the first outer peripheral notch portion and the first outer peripheral leg portion. Preferably, the first outer peripheral leg portion and the second outer peripheral leg portion are suspended in a direction that does not hinder the direction of water flow to the drain. It is.
If comprised in this way, it will become easy to manufacture by bending formation, and drainage to a drain can be performed to lubrication.

  Further, at this time, as described in claim 4, the upper leg formed by bending from a part of the periphery of the upper member is suspended toward the drain, and the upper leg is connected to the drain. It is preferable to hang down in a direction that does not obstruct the direction of water flow and to be in contact with at least a part of the peripheral edge of the drain because the upper surface member can be easily supported.

Further, at this time, as described in claim 5, if the upper surface member is provided with a work hole for attaching and detaching the upper surface member from the frame member, the upper surface member can be easily attached and detached (particularly, ), Which is preferable.
If this working hole is set to a size that can be used by an adult's finger, a special jig is not required and it can be easily attached and detached.
In addition, when two holes are formed in parallel, it is possible to pick them up, particularly when removing the upper surface member, so that the workability is further improved.

The drainage portion covering member according to the present invention is divided into parts, each of which is formed with a leg portion to compensate for the difference in height of the water gradient, thereby eliminating unevenness due to the water gradient around the drain. In addition, it is possible to flexibly cope with the inclination of the water gradient and the size change around the drain.
In addition, an inspection opening is formed above the drain, and a removable upper surface member is disposed in the opening, so that the upper surface member usually eliminates unevenness and forms a flat upper surface. At the time of inspection or cleaning, the upper surface member can be removed and the drain can be accessed from the opening.
Thus, in the drainage part covering member according to the present invention, work such as inspection and cleaning of the drain can be easily performed while solving unevenness due to water gradient.
Moreover, it can respond flexibly to the water gradient size around the drain.

That is, the second outer peripheral leg portion 12e is formed by bending the vicinity of the second outer peripheral notch configuration second side 12d so that the second outer peripheral leg portion 12e is substantially perpendicular to the main body portion of the second outer peripheral member 12, and the free end edge thereof is outside. By bending in the direction, it is formed in a substantially L shape in side view.
In addition, it is the height of the 2nd outer periphery leg part 12e, ie, the height of the 2nd outer periphery standing part 12f, and let the distance from the 2nd outer peripheral member 12 main body to the 2nd outer periphery grounding part 12g be "distance t2." .

As mentioned above, the 1st outer peripheral member 11 and the 2nd outer peripheral member 12 are comprised, and the 1st outer peripheral member 11 and the 2nd outer peripheral member 12 are made into the 1st outer periphery notch part K1 and the 2nd outer periphery notch part K2. Are combined so that they face each other, one rectangular space (hole) is formed.
The rectangular space (hole) configured in this manner is referred to as “inspection opening K”.
That is, the frame member 1 is formed as a frame-shaped member in which the inspection opening K is formed at the center by combining the first outer peripheral member 11 and the second outer peripheral member 12.

As shown in FIG. 5, the upper surface member 2 according to the present embodiment is a substantially rectangular flat plate member, and the shape and opening area of the inspection opening K are matched with the shape and area of the upper surface member 2. It is configured.
That is, the upper surface member 2 is configured to fit into the inspection opening K formed in the frame member 1.
Upper surface legs 21a and 21a are formed from two opposite sides of the upper surface member 2, respectively.
The side on which the upper leg 21a is formed is referred to as “upper side 21b”.

However, these distances are not limited to this, and it is possible to adjust these distances depending on the degree of inclination of the water gradient, the balance, and the like.
In other words, by adjusting these distances, it is possible to adjust the distance so that the slope is uneven even in any way.

≪About use condition of drainage cover material≫
Next, the usage state of the drainage portion covering member S will be described.
First, FIG. 6 demonstrates the structure of the location where the waste_water | drain part coating | coated member S is used in this embodiment.
A drainage guide groove V3 dug in a groove shape lower than the balcony floor V1 is formed along the waist wall V2 on the waist wall V2 side of the balcony floor V1.

Note that the balcony floor V1 is inclined so as to be slightly lowered toward the drainage guide groove V3 for drainage.
And it is comprised so that the water on the balcony floor V1 may be dropped into the waste_water | drain guide groove | channel V3, and it joins with the waste_water | drain guide groove | channel V3 by the waist wall V2.
A drain D is formed near the waist wall V2 of the balcony floor V1. On the upper surface of the drain D, a filter D2 is disposed so as to prevent dust other than water from falling into the drain D.

Further, as shown in FIG. 7, the peripheral portion D <b> 3 of the drain D is inclined so as to descend toward the drain D.
Of the peripheral portion D3 of the drain D, the downward slope from the outer end of the balcony floor V1 toward the drain D is referred to as “inner slope D32”, and the downward slope toward the drain D from the lower end of the waist wall V2 is “outside”. This is referred to as “inclined surface D31”.
In addition, the arrows in FIG. 6 indicate the direction of the water gradient around the balcony floor V1 and the drain D.

Next, the arrangement state of the drainage portion covering member S will be described with reference to FIG.
In the present embodiment, the maximum difference in the water gradient of the outer inclined surface D31 (the difference between the lower end of the waist wall V2 and the upper surface of the drain D) is defined as “the height difference t4”, and the peripheral portion D3 of the drain D is configured. When the maximum height difference of the water gradient of the inner inclined surface D32 (the drop between the peripheral D3 side end of the balcony floor V1 and the upper surface of the drain D) is “height difference t5”,
Distance t1 = distance t2 = distance t3 = height difference t4 = height difference t5
It is comprised so that.

Further, the surface area of the drainage portion covering member S is configured to match or slightly larger than the occupied area of the peripheral portion of the drain D.
In particular, as shown in FIG. 8, when the first outer peripheral member 11 and the second outer peripheral member 12 are combined, the width t6 of the frame member 1 (the distance from the first outer peripheral member 11 to the second outer peripheral member 12). ) Is configured to be slightly larger than the width t7 (the distance from the waist wall V2 toward the room side) of the peripheral portion D3 of the drain D.

The outer peripheral member width of the first outer peripheral member 11 (direction along the direction in which the cutout portion K1 is cut: a direction parallel to the short side) is defined as a width t61, and the outer peripheral member width (notch of the second outer peripheral member 12). A direction along the direction in which the portion K2 is cut: a direction parallel to the short side is defined as a width t62 (width t61 + width t62 = width t6).
Further, the outer width of the peripheral portion D3 of the drain D (the distance from the lower end on the waist wall side to the center line L along the waist wall V2 of the drain D) is defined as a width t71, and the inner width of the peripheral portion D3 of the drain D (balcony A distance from the waist wall side end of the floor V1 to the center line L along the waist wall V2 of the drain D is defined as a width t72 (width t71 + width t72 = width t7).

Since it is configured in this manner, the first outer peripheral leg portions 11e and 11e are erected in the vicinity of the drain D of the outer inclined surface D31, and the second outer peripheral leg portions 12e and 12e are positioned in the vicinity of the drain D of the inner inclined surface D32. The drainage portion covering member S covers the peripheral portion D3 of the drain D, and the first outer peripheral leg portions 11e and 11e, the second outer peripheral leg portions 12e and 12e, and the upper surface leg portions 21a and 21a, The upper surface of the drainage portion covering member S is flush with the balcony floor V1.
That is, the unevenness around the drain D formed by the drain D and the downward slope leading to the drain D can be eliminated.
Therefore, when flooring is laid on the balcony floor, a step is formed due to the uneven state, and the design surface can be improved.

Further, at this time, the upper surface member 2 is configured to be disposed at a position directly above the drain D.
For this reason, when the upper surface member 2 is removed from the frame member 1, the drain D is exposed as shown in FIG.
Therefore, it is possible to prepare for inspection, repair, cleaning, etc. of the drain D portion.

Further, the boundary between the first outer peripheral member 11 and the second outer peripheral member 12 is preferably a position where the inclination of the floor surface changes.
In the present embodiment, it is desirable that the height of the boundary between the balcony floor V1 and the drainage guide groove V3 can be finely adjusted.
The first outer peripheral leg portions 11e and 11e and the second outer peripheral leg portions 12e and 12e are bent so as not to disturb the water flow direction.
That is, it stands up along the direction of water flow.
For this reason, by providing the drainage portion covering member S, it is possible to effectively prevent the drainage function from being lowered.

Furthermore, the frame member 1 according to the present embodiment is configured to be divided into a first outer peripheral member 11 and a second outer peripheral member 12.
For this reason, by adjusting the width t61 and the width t62, even if the distance relationship between the waist wall V2, the drain D, and the waist wall side ends of the balcony floor V1 is different, it can be dealt with easily and flexibly.
In the present embodiment, the first outer peripheral leg portion 11e and the second outer peripheral leg portion 12e have the same length (distance t1 = distance t2). When the maximum height difference of the water gradient of the inner inclined surface D32 is different (height difference t4 ≠ height difference t5), by changing the length of the first outer peripheral leg portion 11e and the second outer peripheral leg portion 12e according to this, It becomes possible to respond easily and flexibly.
That is, since the frame member 1 is configured to be divided into the first outer peripheral member 11 and the second outer peripheral member 12, even if the size of the peripheral portion D3 of the drain D changes, the change can be flexibly and easily handled. It becomes possible.

Furthermore, in this embodiment, in order to form the inspection opening K, the first outer circumferential notch K1 and the second outer circumferential notch K2 are notched.
For this reason, the first outer peripheral leg portion 11e and the second outer peripheral leg portion 12e are simplified by cutting out the original mold and bending it when the first outer peripheral cutout portion K1 and the second outer peripheral cutout portion K2 are cut out. It can be bent and formed.
The inspection opening K functions as an inspection opening for the drain D, and the upper surface member 2 is detachably disposed in the inspection opening K.
Therefore, the upper portion of the drain D is usually covered and flush with the upper surface, and when performing inspection, cleaning, etc., the upper surface member 2 can be easily removed to expose the drain D.
