The enlarged base may be inserted and fitted.

Next, an example of a method for forming a groove according to the present invention will be described. That is, the method of the present invention includes a step of installing a seat, a step of holding a groove member, a step of forming a water gradient, and a step of placing concrete.

First, as shown in FIG. 2, a hole slightly larger than the groove member 10 is dug into a groove to be set in a groove setting portion to form a groove setting recess 50, and concrete is formed on the bottom surface of the recess 50. It is cast and made flat. A plurality of seats 20 are arranged on the bottom surface of the recess 50 at predetermined intervals in the longitudinal direction, and an installation process of the seats is performed. The number of the seat portions 20 is two or more for one groove member 10. In addition, the recess 5
An anchor 51 such as a vertical angle material is driven into the bottom surface at an interval larger than the width of the groove member 10.

The seat portion 20 is for holding the groove member 10 with an appropriate water gradient, and as shown in FIG. 3, a metal bracket 21 having a groove member holding portion 22 on its upper surface. And upper and lower adjusting screws 26 inserted into both side ends of the bracket 21. This bracket 21
Is a top surface 23 and both side ends 24 formed at both ends thereof,
24, the bottom surface of the groove member 10 is supported from below as shown in the figure. Upper surface part 23 of the bracket 21
Is provided with a hole 25 for mounting the groove member holding portion 22. In addition, screw holes 26a for screwing up and down adjustment screws 26 are inserted into both end portions 24, 24.
Are formed. The vertical adjustment screw 26 is used to change the height of the bracket 21 from the bottom surface of the groove setting recess 50 by appropriately rotating the screw to change the length of the protrusion from the lower surface of the both end portions 24. Thereby,
The bottom surface of the groove member 10 held by the groove member holding portion 22 is raised so that a desired water gradient can be formed in the groove member 10.

The groove member holding portion 22 has an L-shaped cross section having a downwardly bent claw 27 at the upper end and a projection 28 formed on the lower surface.
By being engaged with the holes 25 of the bracket 21, they are attached to the upper surface of the bracket 21 so as to face each other at a distance equal to the width of the groove member 10.

Next, a step of holding the groove member is performed. In this step, the two groove member holding portions 22 and 2 of the seat portion 20 arranged on the bottom surface of the groove setting recess 50 by the seat mounting step.
Between the two, the groove member 10 is inserted and pushed downward. Thereby, as shown in FIG. 4, the claw 27 at the upper end of the groove member holding portion 22 of the seat portion 20 engages with the engagement portion 19 formed on the outer surface of the side portion 14 on the bottom surface of the groove member 10. The groove member 10 is locked and held on the upper surface of the seat 20.

Then, other groove members 10 are formed in the same manner as described above.
Are also arranged in the longitudinal direction, and are locked and fixed to another seat 20.
At this time, if one end of the positioning pin is inserted from the end face side of the C-shaped holding portion 17b and the other end is inserted into the C-shaped holding portion 17b of the adjacent groove member 10, the plurality of groove members 10 are securely connected. can do. In addition, as shown by dotted lines in FIGS. 2 and 5, the C-shaped holding portion in a portion where the positioning pin is not inserted, such as an intermediate portion of the groove member 10,
The enlarged base of the anchor rod is inserted. The anchor portion of this anchor rod is locked by the anchor 51 made of the vertical angle material or the like, and the side portions 12,
12 is pulled outward to prevent the side portions 12, 12 of the groove member 10 from falling inward during the later concrete casting. In the case where a water gradient is provided in a part of the groove, the groove member 10 in which the upper end of the side surface portion 12 is inclined is held in the seat portion 20 where the water gradient is provided, and the portion where the water gradient is not provided is provided. Holds a groove member (not shown) in which the upper end of the side portion 12 is not inclined, and connects both groove members to the C-shaped holding portion 17b.
What is necessary is just to connect using.

Thereafter, a water gradient forming step is performed as follows. That is, the vertical adjustment screw 26 of the seat 20 at the desired position holding the groove member 10 is rotated to adjust the protrusion length of the screw from the lower surface of the both ends 24 of the bracket 21. Then, as shown in FIGS. 5 and 6, the height of the bracket 21 from the bottom surface of the groove installation recess 50 is adjusted so that the upper end of the side portion 12 of the groove member 10 is horizontal. At this time, since the upper end of the side surface part 12 is formed in advance in a state of being inclined with respect to the longitudinal direction of the inner surface of the bottom surface part 11, the upper end of the side surface part 12 is made horizontal, The part 11 is inclined and a water gradient is formed. In addition, the formation of the water gradient can be performed very simply and accurately because the work may be performed with the upper end of the side surface portion 12 of the groove member 10 as a guide. In addition, the groove member 10 in which the upper end of the side part 12 is inclined in the longitudinal direction of the inner surface of the bottom part 11 as described above, and the groove member in which the upper end of the side part 12 is not inclined in order to partially form the water gradient Are provided on the bottom surface of the recess 50 by connecting them, the water gradient forming step is performed only on the portion of the groove member 10 in which the upper end of the side portion 12 is inclined.

Next, a concrete casting step is performed. That is, concrete C is poured into the outside of the side of the groove member 10 to fill the space outside the seat 20 and the groove member 10. At this time, even if the side portions 12, 12 of the groove member 10 are weighted with concrete or the like, since the side portions are pulled outward by the anchor rods, they do not fall inward.

Thereafter, the spacer 31 and the cushion 32 are placed on the grating receiving portion 17a of the groove member 10, and the grating 33 is disposed on the cushion 32. The spacer 31 is formed of a hollow rod-shaped body such as a hard vinyl chloride resin. By changing the thickness of the spacer 31 or eliminating the spacer 31, it is possible to cope with a change in the thickness of the grating. The cushion material 32 is for preventing the rattling of the grating 33, and rubber, rubber sponge, resin foam, soft vinyl chloride, or the like is used.

[0023]

As described above, according to the groove member and the method of using the groove member according to the present invention, the upper end of the groove member is inclined so as to be horizontal by the screw for adjusting the vertical position of the seat. Thereby, a water gradient can be easily and reliably provided on the groove member. For this reason, it is not necessary to cast mortar or the like on the bottom surface of the groove member, which reduces man-hours and work days, and is extremely excellent in cost and work efficiency.
In addition, since the groove member is made of resin, there is an advantage that there is no possibility of rust or corrosion, and that it is light and easy to handle. Moreover, since the groove main body is smoother than that made of concrete, dirt and the like are less likely to adhere, and even if it adheres, cleaning is easy. Further, in the case where the side surface portion of the groove member is a plate-shaped main body portion and the upper end portion engaged with the upper end thereof, the main body portion of the side surface portion is exchanged depending on the presence or absence of a water gradient or the degree of the water gradient. By simply doing so, it is possible to cope with the case where the water gradient is provided or not, and further, the degree of inclination of the water gradient. Therefore, the groove member can be used for common parts, and there is also an effect that molding cost, component management cost, and the like are reduced.
