ていることも多々ある。[Prior Art] The U-shaped groove is made by inserting a U-shaped groove member into a groove dug in a land or road edge, and then backfilling the U-shaped groove member with soil or concrete around the U-shaped groove member. It is often constructed by casting. Further, the groove into which the U-shaped groove member is fitted is not always straight, and is often bent with a large radius of curvature.

Then, a gap is unavoidable between the adjacent U-shaped groove members. Therefore, conventionally, the gap has been closed by a convenient method such as covering the gap to keep the watertightness between the U-shaped groove members.

溝幅寸法などに関係する。The U-shaped groove members A, A'connected in this way are relatively rotatable within a range of a predetermined angle about the fitting point P, and even if they are relatively rotated within the range, the other end 3 ' There is no situation in which the rotation and the overhanging portion 21 of the outer fitting portion 2 interfere with each other to hinder the rotation thereof. Further, within the above range, the inner surface of the overhanging portion 21 of the outer fitting portion 2 and the other end portion 3'will always be in contact with each other, and the cover will be provided between the U-shaped groove members A, A '. The unavoidable gap is closed by the sealing material 16 'without forming a large gap that must be provided. That is, the gap unavoidably formed between the outer fitting portion 2 and the other end portion 3'fitted thereto is the sealing material 16 '.
Is closed by closely contacting the inner surface of the outer fitting portion 2 and the outer surface of the other end portion 3 ', and reliable watertightness is given to the connection point. Therefore, the bending angles of the two U-shaped groove members are appropriately set by adjusting the relative rotation angle to the bending angle of the groove dug in the road edge or the land. Here, the range in which the relative rotation of the U-shaped groove members A and A'is allowed is such that the end edge of the outer fitting portion 2 is the other end portion 3 when the U-shaped groove members A and A'are in a straight line. It is a range up to the side wall 12 'of the', and the range is related to the length of the overhanging portion 21 and the groove width dimension of the U-shaped groove member bodies 1, 1 '.

得る曲り角度を大きくとることが可能になる。In the case of general construction on the groove side, the range, that is, the bending angle θ of the two U-shaped groove members A and A ′ is sufficient to be about 15 degrees, and the bending angle beyond that is less necessary and the seal is not necessary. In order to secure a reliable watertightness at the connection point by the material 16 ', the smaller the bending angle is, the more preferable it is. The U-shaped groove members A and A'have a groove width of about 370 mm at the upper end of the side wall and a groove height of 280 mm.
When it is set to about mm, it is possible to secure the watertightness even if the bending angle θ is set to 11 degrees. It should be noted that if the sealing material 16 'is made thick, it becomes possible to increase the bending angle capable of ensuring the watertightness.

Furthermore, the outer fitting part 2
The gap formed between the other end 3 ′ and the other end 3 ′ fitted to it may be closed with an adhesive having a sealing function.

8 and 18 ', and the U-shaped metal fitting 4 shown in detail in FIG. 5 is fitted to the overlapping portion of the edge portions 18 and 18', and the U-shaped metal fitting 4 and the U-shaped groove member A on one side. The protrusion 51 of the anchor 5 shown in detail in FIG. 6 is sandwiched between the edge 18 and the edge 18, and the screw 6 is screwed into the screw hole 41 of the U-shaped bracket 4 to remove the edge 18,1.
The overlapping part of 8'is tightened. This way,
The fitting state of the fitting portion P between the concave portion and the convex portion is ensured, and at the same time, the reliability of the watertightness of the sealing material is improved. Also,
Lifting is prevented by the anchor 5. If the bar 8 is laid horizontally between the U-shaped metal fittings 4 and 4 as shown in FIG. 4, the groove width dimension at the connection point is less likely to be distorted. Besides, before the screw 6 is tightened, the protrusion 5 of the anchor 5 has a U-shaped metal fitting 4 and an edge 18 of the U-shaped groove member A.
Just by inserting it between the and
If the height is set to be approximately the same as the height of the U-shaped groove members A and A ', the width and depth of the groove into which the U-shaped groove members A and A'are fitted are not widened or deepened. However, there is an advantage that it can be easily arranged in the groove.

Therefore, it becomes possible to bend and connect the U-shaped groove member with a large radius of curvature that does not allow the use of existing bend joints, and a convenient and cumbersome method of closing the gap at the connection point with a cover is adopted. There is no need. Further, at the connection point, the outer fitting portion of the U-shaped groove member and the other end portion of the U-shaped groove member adjacent to the outer fitting portion are fitted together, so that there is a gap between the outer fitting portion and the other end portion. There is also an effect that a reliable watertightness can be secured only by closing with a sealing material or an adhesive having a sealing function.
