Thus, according to the technology according to Patent Document 1 and Patent Document 2, the grating for the purpose of covering the drainage groove is disclosed, and drainage such as rainwater is also possible.
However, a finishing material such as a balcony mat may be disposed on the floor of the balcony or the like, and the finishing level differs depending on whether or not the balcony mat is disposed.
In such a case, gratings with different height sizes are required, which is disadvantageous in terms of cost, workability, and the like.

The object of the present invention is to solve the above-mentioned problems, and it is possible to adjust the height at the site, and to cope with the difference in the floor finish level due to the presence / absence of the laying finish etc. and the thickness difference. It is to provide a grating unit capable of.
In addition, another object of the present invention is to provide a grating unit that can cope with the difference in finishing level due to the presence / absence of a finishing material, etc. and the difference in wall thickness by a simple construction method, and can improve the workability while suppressing cost. There is.

  According to the first aspect of the present invention, there is provided a grating unit for covering the upper part of the drainage channel while securing the drainage channel, the grating unit comprising: a grating receiving member attached to the building frame side; And a grating covering the upper part of the drainage path, wherein the grating receiving member includes a base part extending in the width direction of the drainage path, and a first support wall rising up from the base part. And a second support wall that rises upward from the base portion at a predetermined distance from the first support wall, and the grating includes a top surface portion that covers the drainage channel upper portion with a substantially rectangular flat plate. A first side wall bent and suspended substantially perpendicularly from one long side of the top surface portion; and a first side wall bent substantially vertically from a long side opposite to the long side from which the first side wall is suspended; Also the top part A second side wall having a long hanging distance, a first locking side wall depending from the top surface portion so as to be in the same direction and substantially parallel to the first side wall and the second side wall, the first side wall, The first side wall is suspended from the top surface portion so as to be in the same direction and substantially parallel to the second side wall and has a longer distance from the top surface portion than the first locking side wall. A second locking side wall disposed on the side, and suspended from the top surface portion so as to be in the same direction and substantially parallel to the first side wall and the second side wall, and more than the second locking side wall. And a third locking side wall which is disposed closer to the first side wall than the second locking side wall, and the hanging distance from the surface portion is short. The first supporting wall and the second locking wall The distance from the base portion of the support wall is formed substantially the same, the first locking side wall and the third locking side The hanging distance from the top surface part to the wall and the hanging distance from the top surface part of the second side wall and the second locking side wall are formed substantially the same, and the first locking side wall and the The distance between the third locking side wall and the distance between the second side wall and the second locking side wall are substantially the same, and the third locking side wall is related to the first support wall. When the first locking side wall is locked to the second support wall, the grating is reversed to lock the second side wall to the first support wall and the second locking side wall. In the case where is fixed to the second support wall, this is solved by the fact that the distance in the height direction between the base portion and the top surface portion is different.

As described above, the grating unit according to the present invention includes the grating receiving member and the grating.
The grating has a first side wall, a second side wall, a first locking side wall, a second locking side wall, and a third locking side wall that hang down in the same direction from the top surface in a substantially parallel manner. ing.
And these are the 2nd locking side wall and the 2nd side wall (substantially the same length) with a large hanging distance from a top surface part, and the 1st locking side wall and the 3rd locking side wall with a small hanging distance from a top surface part. The first side wall, the first locking side wall, the second locking side wall, the third locking side wall, and the first side wall are arranged in this order.
Further, the distance between the first locking side wall and the third locking side wall and the distance between the second side wall and the second locking side wall are substantially the same.
Therefore, when the third locking side wall is locked to the first supporting wall and the first locking side wall is locked to the second supporting wall, the grating is reversed, and the second side wall is engaged with the first supporting wall. In the case where the second locking side wall is locked to the second support wall while stopping, the height direction distance between the base portion and the top surface portion is different.
That is, the height from the base portion to the top surface portion is changed by changing the assembly direction of the grating.
Therefore, it is possible to adjust the height of the grating unit on site, and it is possible to cope with the presence or absence of a finishing material or the like to be laid.
That is, when the grating is assembled to the grating receiving member so that the third locking side wall is locked to the first support wall and the first locking side wall is locked to the second support wall, Since the side wall and the third locking side wall have a small hanging distance from the top surface portion, the vertical height of the grating unit is reduced.
On the other hand, the grating is assembled to the grating receiving member so that the second side wall is locked to the first support wall (invert the grating unit) and the second locking side wall is locked to the second support wall. In addition, since the second side wall and the second locking side wall have a large hanging distance from the top surface, the vertical height of the grating unit is increased.
Therefore, even if a floor mat or the like is laid and the distance from both ends of the drainage path to the top surface of the floor mat is larger than the distance from both ends of the drainage path to the floor of the veranda, the second side wall is locked to the first support wall. In addition, it is possible to easily cope with this by assembling the second locking side wall in the direction of locking to the second support wall.
As described above, according to the grating unit according to the present invention, it is possible to cope with the difference in the finishing level depending on the presence or absence of the finishing material, etc., so that it is possible to reduce the variation of the product size, and to reduce the cost. Workability can be improved.

  Further, at this time, a plurality of the grating receiving members are provided, and the base portion is bent at an obtuse angle with the support portion from a substantially rectangular flat plate support portion and each side of the support portion facing each other. The first support wall and the second support wall are configured such that the leg part hangs down from a position close to the opposing sides of the support part. The support portion is disposed across the upper portion of the drainage path by standing substantially perpendicular to the support portion on the opposite direction side and disposing the legs at both ends in the width direction of the drainage path. In addition, it is preferable that the first support portion and the second support portion are configured to be respectively disposed at the upper portions on both ends in the width direction of the drainage path.

Thus, by arranging a plurality of grating units, rainwater or the like can be dropped and discharged to the drainage path from between adjacent grating receiving members.
In addition, since the grating is supported by the plurality of grating receiving members, it is easy to cope with the shape of the drainage path, and the grating can be reliably supported.

  Furthermore, in the invention according to claim 1, the first support wall, the second support wall, the first locking side wall, the second locking side wall, the third locking side wall, and the second side wall include: A concave portion or a convex portion for constructing an engagement state is formed, and the concave portion or the convex portion forms the first support wall and the first locking side wall or the second side wall and the second support wall. It is preferable that the engagement state of the first locking side wall or the second locking side wall is constructed.

  In this way, by constructing the engaged state, the grating and the grating receiving member can be securely attached and can be unitized.

In the grating unit according to the present invention, the grating is assembled to the grating receiving member so that the third locking sidewall is locked to the first support wall and the first locking sidewall is locked to the second support wall. And since the hanging distance from the top | upper surface part is small for the 1st locking side wall and the 3rd locking side wall, the height of the up-down direction of a grating unit becomes small.
On the other hand, the grating is assembled to the grating receiving member so that the second side wall is locked to the first support wall (invert the grating unit) and the second locking side wall is locked to the second support wall. In addition, since the second side wall and the second locking side wall have a large hanging distance from the top surface, the vertical height of the grating unit is increased.
In this way, the height of the grating unit can be adjusted on the spot only by changing the mounting direction of the grating, and it is possible to cope with the presence or absence of a finishing material to be laid.

  In addition, the grating unit according to the present invention is a simple construction method (only inversion of the grating), and can cope with the difference in the finishing level depending on the presence or absence of the finishing material, etc., thereby reducing the variation of the product size and suppressing the cost. It is possible to improve workability on site.

In other words, any shape, number, formation position, etc. may be designed as long as the engagement state can be formed.

Next, the usage pattern of the two patterns of the grating unit S will be described with reference to FIGS.
First, the first usage pattern will be described with reference to FIGS.
As shown in FIG. 4A, the first locking side wall locking portion 14 a formed on the first locking side wall 14 is formed in the second support wall side engagement space 24 c formed on the second support wall 24. Inserted and locked.

The third locking side wall locking portion 16 a formed on the third locking side wall 16 is locked to the first support wall engaging portion 23 a formed on the first support wall 23.
At this time, the lower end portion of the third locking side wall locking portion 16 a is placed and supported on the first placement surface 23 </ b> B constituting the first support wall 23.
Further, at this time, the second locking side wall locking portion 15 a formed on the second locking side wall 15 is placed on the upper surface of the support portion 21.
The state assembled in this way is shown in FIGS.

Next, a second usage pattern will be described with reference to FIGS.
The second side wall locking portion 13 a formed on the second side wall 13 is locked to the first support wall engaging portion 23 a formed on the first support wall 23.

At this time, the lower end portion of the second side wall locking portion 13 a is placed and supported on the first placement surface 23 </ b> B constituting the first support wall 23.
The second locking side wall locking portion 15 a formed on the second locking side wall 15 is inserted and locked in the second support wall side engagement space 24 c formed on the second support wall 24.

Thus, in the second usage pattern, the grating 1 is used after being inverted from the state of the first usage pattern.
That is, in the first usage pattern, the first side wall 12 constituting the grating 1 is disposed on the first support wall 23 side constituting the grating receiving member 2, and the second side wall 13 constituting the grating 1 is The direction of the grating 1 is determined and attached to the grating receiving member 2 so as to be disposed on the second support wall 24 side constituting the grating receiving member 2.

  On the other hand, in the second usage pattern, the second side wall 13 constituting the grating 1 is disposed on the first support wall 23 side constituting the grating receiving member 2, and the first side wall 12 constituting the grating 1 is The direction of the grating 1 is determined and attached to the grating receiving member 2 so as to be disposed on the second support wall 24 side constituting the grating receiving member 2.

In this state, when the grating 1 is attached to the grating receiving member 2 as described above, the height of the first locking side wall 14 from the top surface portion 11 is h1, and the top of the second locking side wall 15 is as described above. When the height from the surface portion 11 is h2, the height from the top surface portion 11 of the third locking side wall 16 is h3, and the height from the top surface portion 11 of the second side wall 13 is h4, (h4 ≧ h2)> ( h3 ≧ h1).
Note that h4 and h2 and h3 and h1 have substantially the same height.

Since it is comprised in this way, the height of the grating unit S will differ in a 1st usage pattern and a 2nd usage pattern.
That is, in the present embodiment, the height of the total grating unit varies due to the difference in height between the first locking sidewall 14 and the second locking sidewall 15 (h2, h4> h1, h3).

This difference is shown in FIG.
As shown in FIG. 8, the difference (h2 (h4) −h1 (h3)) Δh between the height of the second locking sidewall 15 and the height of the first locking sidewall 14 is the grating unit S in the first usage pattern. And the vertical height of the grating unit S in the second use state.

As described above, in this embodiment, the height of the grating unit S can be made different only by changing the arrangement direction of the grating 1.
Therefore, in the present embodiment, two size variations can be realized with the grating unit S of one size.

A usage example of the grating unit S according to the present embodiment will be described with reference to FIGS. 9 and 10.
FIG. 9 shows a case where a thin-walled finishing material R1 is laid on the balcony floor, and FIG. 10 shows a case where a thick floor mat R2 is laid on the balcony floor.
As shown in FIG. 9, when the finishing material R1 is laid, the grating unit S according to the first usage pattern is used.

On the other hand, when the thick floor mat R2 is laid, the grating unit S according to the second usage pattern in which the height in the vertical direction is larger than that in the first usage pattern is used.
In such a case, when the grating unit S according to the first usage pattern is used, a step is formed between the upper surface of the floor mat R2 and the upper surface of the grating 1, and the user apologizes to step on the leg. Various problems arise, such as curling or undesirable design.

  In the prior art, since the grating itself is not configured as a separate body and is not a structure that can be adjusted in height, in order to solve such a problem, the product size (vertical height) is different. There was a need to produce variations.

  However, since the grating unit S in the present embodiment is formed separately in the grating 1 and the grating receiving member 2 and adopts a structure in which the height can be changed, the arrangement direction of the grating 1 is changed. Only by changing the height of the grating unit S, it is possible to easily cope with such a state.

Next, the drainage route is shown in FIG.
In the grating unit S according to the present embodiment, rainwater or the like that has dropped onto the top of the grating 1 falls along the outer side surface of the first side wall 12 and the second side wall 13 (flow guide part 13A), and receives adjacent gratings. It is comprised so that it may discharge | emit to a drainage channel through between the members 2 and 2.

As described above, according to the grating unit S according to the present embodiment, the height level in the vertical direction can be easily changed by simply inverting the grating 1 and changing the mounting direction.
Therefore, even when the floor mat R2 or the like is laid on the floor of a balcony or the like, it can be easily dealt with, and there is no need to prepare a height variation of the product.
