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] A conventional joint structure of this type of gutter body is, for example, a gutter-like gutter body with a concave cross-section, which extends outward along the left and right side walls and the longitudinal ends of the floor. A flange having a rising portion is formed, and the side gutter bodies are arranged in a row so as to be in contact with each other at the rising portion of the flange, and bolt holes that communicate with each other are provided in both flanges that are in contact with each other. A plurality of bolt holes are provided, and both flanges are connected in abutting state by bolts inserted into these bolt holes and nuts screwed to the bolts, thereby connecting the both side groove bodies to each other.

However, since the joint structure of the conventional gutter body is as described above, when connecting the gutter bodies on both sides, it is necessary to connect a plurality of bolts and nuts, and when disassembling the body, it is necessary to connect the bolts and nuts. There is a problem in that the nut must be removed, which is a very troublesome process.

[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. A flange including a rising portion extending outwardly along an end portion is formed, and the side gutter bodies are disposed in a row so as to be in contact with each other at the rising portion of the flange, and are cylindrical and have a cylindrical shape. A connecting member having a notch formed along the longitudinal direction for holding the two rising parts that are in contact with each other is connected to the flange by inserting the two rising parts that are in contact with each other into the notch from the open part. 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 fitting the two side gutter bodies together and connecting the side gutter bodies to each other.

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

1 and 2 are an exploded perspective view and a plan view of essential parts of a side gutter body formed by applying the joint structure of the side gutter body of this invention. It is a side gutter body with a concave cross-sectional shape, and includes rising portions 4 and 5 extending substantially perpendicularly to the outside at both left and right side walls 2 of the side gutter body 1 and both ends of the floor portion 3, and in particular, the rising portions of the left and right side walls 2 A folded portion 6 is formed at the tip of the portion 4, so that the overall cross-sectional shape is approximately L-shaped. Flanges 7 and 8 are formed respectively. Both side groove body 1 has flanges 7,
8, they are arranged in series in abutment with each other.

Further, as shown in FIG. 3, a notch 11 is formed which has a cylindrical shape with a square cross section and has open portions 9 and 10 at both ends along the longitudinal direction. A connecting member 13 in which an outwardly expanding inclined portion 12 is formed in the open portion 10.
(as shown in the third figure), both rising portions 4 are
are engaged with both flanges 7 by sequentially inserting them into the notches 11 while drawing them together. Then, the two upright portions 4 are held in contact with each other by the notch 11, and the groove bodies 1 on both sides are connected. Further, the connecting member 13 is prevented from coming off by the folded portion 6.

Along the upper edges of both side walls 2 of the side gutter body 1, overhanging parts 14 are formed which overhang in the left and right outward directions, and as shown in FIG. A reinforcing member 15 having a downward U-shaped cross section is fitted to cover both overhanging portions 14 from above, and is further screwed to both overhanging portions 14 with bolts 16 to further strengthen the connected state of both side groove bodies 1. It is also possible to reinforce it.

Further, as shown in FIG. 1, both the flanges 7,
A packing 17 made of an elastic material and having a circular cross section is interposed between the two, and it is also possible to abut and fix the two in a water-tight manner.

4 to 8 are plan views of essential parts of side gutter bodies 1 connected to each other by the joint structure of this invention in different embodiments. First of all, FIG. 4 or 5 shows flanges 7 abutted against each other,
The cross section of the packing 17 interposed between the holes 8 and 8 is circular or rectangular. Moreover, FIGS. 6 to 8 each show the connecting member 1 in FIG. 5.
3 with a different cross-sectional shape, especially the one shown in FIG.
A notch 11 is formed at the tip of the flange 7, and the base end of the rising portion 4 of the flange 7 is pressed in the direction of contact. In addition, in the one shown in Fig. 7, the outer convex portion 1
8 and an inner convex portion 19 that protrudes in the cylinder direction of the connecting member 13 is formed in the same portion, and both convex portions 18, 19
While being brought into contact with the folded portion 6 of the flange 7 and the left and right side walls 2, both the rising portions 4 are pressed by the notch 11 in the direction of contact with each other. Further, in the one shown in FIG. 8, an inner convex portion 19 is formed that projects into the cylinder of the connecting member 13, and the notch 11 is formed at the tip of this inner convex portion 19, and the notch 11 allows the above-mentioned It is pressed in the direction in which the tip of the rising portion 4 comes into contact. In either case, the grooves 1 on both sides can be easily connected in a water-tight manner as described above.

[Operation of the invention] Since the joint structure of the gutter body of this invention is as described above, when connecting the gutter body 1, for example, when the packing 17 is interposed between both flanges 7 and 8, first The packing 17 is pasted on the contact surfaces of the flanges 7 and 8, and the grooves 1 on both sides are connected so that the contact surfaces of the flanges 7 and 8 of the left and right walls 2 and the floor 3 are in contact with each other. Arrange it in a row. Then, the connecting member 13 is inserted into the notch 11 in order from the upper end of both flanges 7 of both side walls 2 through its sloped portion 12, and at this time, both flanges 7 are drawn together by the sloped portion 12, and the left and right side walls 2 and The flanges 7 and 8 of the floor part 3 are abutted and fixed to each other in three directions through packing 17 in a water-tight manner. Furthermore, when the reinforcing material 15 is used, the reinforcing material 15 is fitted into the overhanging portion 14 and fixed with bolts 16, thereby making it possible to connect the both-side groove bodies 1 more firmly.

In addition, when disassembling the connected gutter bodies 1,
When using the reinforcing material 15, remove the bolts 16, remove the reinforcing material 15 from the overhanging portion 14, and pull out both flanges 7 from the notch 11.
The connecting member 13 can be removed, and thereby the both-side groove body 1 can be easily disassembled.

[Effects of the invention] As described above, the joint structure of the gutter body according to this invention has the effect that the gutter body can be easily assembled and disassembled simply by attaching and removing reinforcing materials and connecting members. It is.
