TECHNICAL FIELD The present invention relates to a resin groove.

[0002]

2. Description of the Related Art In recent years, resin-made grooves have come to be used because they are easy to construct and do not rust. This resin groove is shown in FIG. The illustrated resin groove 60 is opposed to a lower side portion 61 having a substantially L-shaped cross section formed of a substantially horizontal surface and a substantially vertical surface, and an upper side portion 65 provided above the substantially vertical surface of the lower side portion 61. The lower side portion 61
Bottom plate 69 sandwiched between the substantially horizontal front ends of the above, and side plate 7 sandwiched between the substantially vertical surface of the lower side portion 61 and the upper side portion 65.
The cross section has a concave shape of 0. The upper side portion 65 constitutes a receiving frame such as a grating that serves as a lid for the groove. A side plate insertion groove 66 is formed at the lower end, and a substantially L-shaped receiving frame portion 67 is formed at the upper portion. There is. Reference numeral 71 is a molding appropriately provided for decoration, and 72 is an anchor member fixing groove.

As shown in FIG. 6, the resin groove 60 having the above structure is installed in the recess 80 formed in the groove installation planned portion as follows. First, the bracket 85 to which the holding member 81 is attached is disposed on the bottom surface of the groove installation planned recess 80.
Next, the resin groove 60 is inserted from above between the holding members 81, 81 and fixed to the holding members 81, 81.

Next, a width determining member 86 having a width (length) substantially equal to the width between the inner wall surfaces is arranged on the receiving frame portions 67, 67 of the upper side portions 65, 65, and the upper side portion 65 has a width (length). One end of an anchor member 87 is attached to the outer surface, and the other end of the anchor member 87 is fixed to an angle member or the like not shown. Then, concrete C is cast on the outside of the resin groove 60. At this time, the width determining member 86 prevents the side surface of the resin groove 60 from falling inward. Then, instead of the width determining material 86 after hardening of concrete, a lid (grating) is arranged on the receiving frame portion 67 of the upper side portion 65, and the groove is completed. Reference numeral B in the figure denotes a screw member for adjusting the horizontal height.

[0005]

By the way, the lid (grating) may not be used on the wall of the building or in the groove provided outside. In such a resin groove that does not use a lid, the upper side portion 65 of the receiving frame shape is unnecessary, and the upper side portion 65 of the receiving frame shape is unnecessary.
Not only will there be a price penalty for using
Since the side surface distance (groove width), which is important for efficient drainage, is narrower than the outer surface distance of the upper side surface, there is a problem that the groove cannot be effectively used.

However, the upper side portion 65 of the receiving frame shape is formed.
The not only increases the rigidity of the side surface of the groove due to the shape of the receiving frame during the construction of the groove, but also exerts the arrangement and fixing action of the width determining member and the anchor member. Therefore, if the upper side portion 65 of the receiving frame shape is eliminated, those actions cannot be obtained, the side surface spacing of the groove is changed when pouring concrete, the anchor effect with concrete cannot be obtained, and peeling off to concrete occurs. Problems such as easiness occur.

The present invention has been made in view of the above points, and in a groove that does not need a lid, the groove width and the groove side surface can be made constant, and the space inside the groove can be effectively used. The purpose of the present invention is to provide a resin groove that is effective.

[0008]

According to the present invention, there is provided a lower side portion having a substantially L-shaped cross section, which is composed of a substantially horizontal surface and a substantially vertical surface, and an upper side portion provided above the substantially vertical surface of the lower side portion. , A resin having a substantially concave cross-section, which includes a bottom plate sandwiched between the substantially horizontal plane tips of the lower side parts facing each other, and a side plate sandwiched between the upper end of the substantially vertical surface of the lower side part and the upper side part. In the groove, the upper side portion is formed to have a side plate insertion groove portion on the lower end surface and a width determining material insertion groove portion on the upper end surface, and a main body portion having a substantially H-shaped cross section, and extending from the outer lower end to a substantially horizontal outer side. It is characterized by comprising a locking piece.

On the outer surface of the holding member 38, a downward engaging portion 17 for the holding member 38 is provided.
Are formed. A pair of lower side parts 11 is used such that the ends of the horizontal surfaces 12 face each other and the upper end of the vertical surface 15 faces upward.

The upper side portion 21 includes a body portion 22 and a locking piece 26.
And an integral part of the resin groove 10 and extend along the longitudinal direction of the resin groove 10. As shown in FIG.
The side plate insertion groove portion 23 is formed on the lower end surface, and the width determining material insertion groove portion 24 is formed on the upper end surface, each having a substantially H-shaped cross section formed along the longitudinal direction of the upper side portion 21. The lower end of the locking piece 26, which is the outside of the main body portion 22, is bent in a substantially L shape and extends substantially horizontally, and a locking portion 27 having a vertically enlarged shape is formed at the tip. . The locking piece 26 is for obtaining an anchor effect on the concrete cast outside the resin groove 10 in the groove installation recess. In this embodiment, the thickness a is 5 mm and the width b is 30 mm. The vertical dimension c of the locking portion 27 is 10 mm.

The locking pieces 26 do not have to be provided over the entire length of the main body portion 22 of the upper side portion 21, but may be provided intermittently at predetermined intervals. A pair of the upper side portions 21 are arranged above the substantially vertical surface 15 of the lower side portion 11 with the locking pieces 26 of each pair being substantially horizontal outside.

The bottom plate 31 is a plate-like member having a predetermined width and length, and is a substantially horizontal plane 12 of the lower side portion 11 of the set.
Both ends in the width direction are inserted into the bottom plate insertion groove portion 13 at the tip, and the substantially horizontal surface 12 of the lower side portion 11 constitutes the bottom surface of the groove. By appropriately determining the width of the bottom plate 31, the width of the groove can be made a predetermined dimension.

The side plate 35 is a plate-shaped member having a predetermined width and long in the longitudinal direction of the resin groove 10.
Side plate insertion groove 16 at the upper end of the substantially vertical surface 15 and the upper side 2
Both upper and lower ends are inserted into the side plate insertion groove portion 23 at the lower end of the main body portion 22 of No. 1, and the substantially vertical surface 15 of the lower side portion 11 and the main body portion 21 of the upper side portion 21 form the side surface of the groove.

Next, an example of construction of the resin groove 10 thus constructed will be shown. First, as shown in FIG. 3, a groove slightly larger than the resin groove 10 is dug in a groove installation planned portion to form a groove installation recess 50, and concrete is placed on the bottom surface of the recess 50. And make it a plane. On the bottom surface of the recess 50, the brackets 43 to which the holding member 38 is fixed are arranged at predetermined intervals in the longitudinal direction. The number of holding members 38 and brackets 43 is two or more for a series of resin grooves 10.

As can be seen more clearly from FIG. 1, the holding member 38 has a claw 39 which is bent downward at the upper end and has an L-shaped cross section with a protrusion 40 formed on the lower surface and is made of resin. . On the other hand, the bracket 43 is made of a metal plate and is composed of a central portion 44 and both end portions 45 formed at both ends thereof, and has a shape to support the bottom surface of the groove 10 from below. Fixing holes 46 for the holding member 38 are provided on both sides of the central portion 44 of the bracket 43, and the projection 40 of the holding member 38 is inserted and locked in the hole 46 to hold a pair of holding members. The member 38 is fixed to the upper surface of the bracket 43. Further, screw holes 47 are formed in both side ends 45 of the bracket 43, and vertical adjusting screws B are screwed into the screw holes 47. The vertical adjusting screw B is appropriately rotated to change the protruding length from the lower surface of the both side end portions 45, thereby changing the height of the bracket 38 from the bottom surface of the groove installation recess 50, and the water gradient of the groove 10. It is for adjusting.

Next, the resin groove 10 is attached to the holding member 3
Insert between 8 and 38 and push downward. As a result, in the downward engaging portion 17 of the lower side portion 11 of the resin groove 10,
The claw 39 at the upper end of the holding member 38 is engaged, and the resin groove 1
0 is locked and held on the bracket 43.

Subsequently, a width determining member 48 for the resin groove 10
Set. This width determining member 48 is the resin groove 10
Of the plate or the square bar having a width (or length) substantially equal to the width between the inner wall surfaces of the projections 49 formed on the lower surfaces of both ends.
Is fitted into the width determining material insertion groove portion 24 on the upper end surface of the upper side portion 21 so as to be locked to the upper portion of the groove 10. It is not necessary to provide the width determining members 48 so as to completely cover the groove 10, and an appropriate number of width determining members 48 may be provided at predetermined intervals.

Then, concrete C is poured into the outer portion of the resin groove 10 to fill the outer space of the resin groove 10 with concrete. After hardening of the concrete, as shown in FIG. 4, if the width determining member 48 is removed from the upper side portion 21 of the resin groove 10, the construction of the groove 10 is completed. In this way, the resin groove 10 provided near the wall of the building is firmly integrated with the concrete because the locking piece 26 of the upper side portion 21 is fixed in the concrete and exhibits an anchor effect. There is no risk of peeling. Further, since there is no space above the groove 10 that cannot be used as the groove, that is, a receiving frame portion such as grating, the space inside the groove 10 can be made larger than the outer diameter dimension of the groove 10, and efficient drainage or the like can be achieved. It will be possible.

[0021]

As shown and described above, in the resin groove of the present invention, the upper side portion, which is provided above the lower side portion having a substantially L-shaped cross section through the side plate, has the lower end surface. Side plate insertion groove, cross-section approximately H with width determining material insertion groove formed on the upper end surface
Since it is composed of a V-shaped main body and a locking piece formed to extend from the outer lower end to a substantially horizontal outer side, it is possible to set the width determining material of the groove between the upper side parts during construction, and after the construction, The locking piece on the upper side portion exerts an anchoring effect on the concrete cast on the outer side portion.

Therefore, by using the resin groove of the present invention in a place where a lid such as a grating is unnecessary, the opening size of the groove upper part can be made constant, and the groove may be firmly integrated with concrete to cause peeling. Absent. Further, since there is no receiving frame portion for the lid, the space inside the groove can be made larger than the outer dimensions of the groove, and drainage or the like can efficiently flow.
