Description

[Detailed description of the invention] [Industrial application field] This invention relates to a joint structure for side gutter bodies used to connect side gutter bodies used as drainage passages for general roads, forest roads, farm roads, or civil engineering works. It is.

[Prior Art] As shown in FIG. 18, for example, a conventional joint structure of this type of side gutter body includes a joint structure in which the right and left side walls 2 and the floor portion 3 of a gutter-like gutter body 1 with a concave cross section are connected in the longitudinal direction. A flange 5 having a rising portion 4 extending outwardly is formed along the end portion, and the side gutter bodies 1 are arranged in a row with each other in contact with each other on the side surfaces of the rising portion 4 of the flange 5. A plurality of bolt holes 6, which communicate with each other, are drilled at appropriate intervals in both flanges 5 which are brought into contact with each other, and bolts (not shown) inserted into these bolt holes 6 are connected by screws. By connecting both flanges 5 in an abutting state with a nut, the groove bodies 1 on both sides are connected to each other.

However, since the joint structure of the conventional side gutter 1 is as described above, the both side gutter 1
When connecting, multiple bolts and nuts must be screwed together, and when disassembling, those bolts and nuts must be removed, which is a very troublesome work, and the gutter body 1 must be connected by screws. When arranging the bolt underground, there is a problem in that it is necessary to form a culvert, etc., taking into consideration the space sufficient for bolting work.

[Means for solving the problem] This invention was devised in view of the above-mentioned circumstances, and its outline is that the left and right side walls and the floor of a gutter-like gutter body with a concave cross-section have a longitudinal direction. Along the ends, strips are formed that stand upright toward the inside of the gutter body, and the side gutter bodies are disposed in series with the side surfaces of the strips facing each other, and are arranged in a cylindrical manner. A connecting member having a shape with a notch formed along the longitudinal direction is installed between the both side groove bodies by inserting and holding both the strips that are in contact with each other into the notch, and the connecting member is constructed between the both side groove bodies. It is an object of the present invention to provide a joint structure of a side gutter body which can be easily disassembled and assembled by being connected to each other.

[Example] An example of this invention will be described below based on the accompanying drawings.

1, 2, and 3 are a partially cutaway plan view, side view, and front view of a side gutter body formed by applying the joint structure of the side gutter body of this invention, and in the drawings, 11 is a The gutter body has a concave cross section and is provided with left and right side walls 12 and a floor portion 13, and on the outside of the gutter body 11, as shown in FIG.
A plurality of reinforcing ribs 14 are formed along the cross section at appropriate intervals.

As shown in FIG. 4, which is an enlarged view of part B in FIG. An arm portion 15 having a Z-shaped cross section is formed, and a strip 16 that stands inward from the tip of the arm portion 15 is integrally formed. A strip member 18 integrally formed with a locking protrusion 17 that protrudes in a direction substantially along the side wall 12 is attached by welding or the like. Further, as shown in FIG. 5, which is an enlarged view of part C in FIG. Strip member 2 that is integrally formed with no locking protrusion 17
1 is attached by welding or the like.

The side gutter bodies 11 are arranged in series so that the outer surfaces 16a and 20a of the strips 16 and 20 of the strip members 18 and 21 are in contact with each other, respectively. As shown in FIGS. 7 and 8, the strips 16 and 20 that are in contact with each other on the outer surfaces 16a and 20a have a rectangular cylindrical shape with a recess 22 formed along the outer side in the longitudinal direction, The notch of the connecting member 26, which is formed in an upward U-shape as a whole by fixing vertical members 25 similarly formed to both ends of the horizontal member 24, in which a notch 23 is formed along the bottom of the recess 22. It is inserted and clamped by 23. Note that the connecting member 26
As shown in FIG. 10, which is a view taken along the line D-D in FIG. A semi-elliptical notch 27 for insertion is formed, and as shown in FIG. 9 as seen from the E-E arrow in FIG. A sloped portion 28 is formed which widens toward the end, making it easier for the strip 16 of the strip member 18 to be inserted into the notch 23 of the longitudinal member 25.

11 and 12 are a side view and a plan view showing a state in which the side gutter bodies 11 are connected by the joint structure of this invention, and FIG. 15 is a
-F arrow view, FIG. 16 shows a GG arrow view in FIG. 12, and FIG. 17 shows a H-H arrow view in FIG. 12, respectively. That is, as shown in FIG. 15, the connecting member 26 is moved downward from the upper opening of the gutter body 11 arranged in series with the outer surfaces 16a, 20a of the strips 16, 20 in contact with each other. At this time, both the strips 16 formed on the left and right side walls 12 of the side gutter body 11 and in contact with each other are held in order by the notches 23 of the vertical members 25 of the connecting member 26. At this time, the connecting member 2 is attached to the locking protrusion 17 of the strip member 18.
6 is locked, connecting member 26 from strip member 18
will be prevented from leaving. Then, the connecting member 26 is further moved downward, and as shown in FIG. Notch 2
3 is inserted and clamped.

Note that the connecting member 26 connects the horizontal member 24 and the vertical member 2.
It is also possible to have a separate configuration in which the strips 5 and 5 are separately engaged with the strips 20 and 16, respectively.

Further, as shown in FIGS. 16 and 17, the space 3 between the connecting member 26 and the strip members 18, 21
A sealing material such as silicone resin is inserted into the connecting portion 0 to maintain watertightness of this connecting portion.

Along the upper ends of the left and right side walls 12 of the side gutter body 11, a projecting portion 31 is formed that extends substantially horizontally in the left and right outward direction, and covers the upper side of both the projecting portions 31 of the connecting portion of the both side gutter body 11. As shown in FIG.
32 (shown) is installed, and the reinforcing member 32 is attached to the overhanging part 31 with bolts 34 and nuts 35 passing through bolt holes 33 formed in the reinforcing member 32 and the overhanging part 31 (17th (illustrated), the connecting portions of the side gutter bodies 11 that are connected to each other are reinforced.

[Effects of the invention] Since the joint structure of the side structures according to this invention is as described above, when connecting the side structures, the side surfaces of the strips formed at the ends of the side structures come into contact with each other. By connecting the side structures like this and sliding the connecting member downward from the inside of the side structures, both strips can be held between the notches and the reinforcing material can be attached. It is possible to connect easily by reducing the number of fasteners. In addition, even if this side structure is installed underground, the connections between the gutter bodies on both sides can be made from the inside of the gutter bodies, so it is only necessary to dig a culvert, etc., that is large enough to accommodate the gutter bodies, making the work easier. This has the following effects.
