ら、該係合構造が簡単に外れてしまう。 For example, composite pipes that protect power transmission cables, etc.
It is arranged in a straight line using a connection structure in which a socket at one end is inserted into a socket at the other end. By the way, when a crack occurs in the ground due to an earthquake or the like, shearing force or tensile force acts on the composite pipe group. In this case, it can withstand shearing forces well, but it is weak against tensile forces, especially in the connecting part structure. In other words, even if an engagement structure such as a serrated engagement is adopted for the connection part, the diameter change will occur in the receptacle or spigot due to the bending that occurs at the same time as tension, so the engagement structure can be easily changed. It will come off.
本考案の目的とするところは、引張り力や曲げ
力に充分に耐えて常に連結状態を維持し得る複合
管の連結部構造を提供する点にある。 An object of the present invention is to provide a joint structure for composite pipes that can sufficiently withstand tensile force and bending force and always maintain a connected state.

いる。 In order to achieve the above object, the joint structure of the composite pipe in the present invention is such that a fiber-reinforced resin socket is formed at one end of the composite pipe, and a fiber-reinforced resin socket is formed at the other end. An O-ring is disposed on the outer surface of the outer end of the spout, and annular recesses are formed on the inner surface of the receptacle and the outer surface of the spigot, respectively, and the inner ring part and the outer ring part are connected and integrated between these recesses. An annular spring material with a V-shaped cross section is arranged so that its connection part is located on the outer end side of the spigot, and the thickness of the spigot part and the thickness of the socket are smaller than the body thickness of the composite pipe. The thickness is set to large.

る。 According to the configuration of the present invention, since the socket and the spigot are made of fiber-reinforced resin and their wall thickness is larger than the thickness of the body, it is possible to prevent the socket and the spigot from changing in diameter. Thus, the connection via the annular spring member can be reliably maintained even when tensile forces or bending forces are applied.

入する状態で配設される。 An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 denotes a composite pipe, which is composed of a laminate of a fiber-reinforced resin outer layer 2, a mortar intermediate layer 3, and a fiber-reinforced resin inner layer 4. A socket 5 made of fiber-reinforced resin of the same quality as the outer layer 2 is formed at one end of the composite pipe 1, and a raised socket 6 made of fiber-reinforced resin of the same quality as the outer layer 2 is formed at the other end. ing.
Note that when forming the spout 6, short glass fibers (chopped strands) may be mixed therein, and a mixture of nylon, polyethylene, mortar, etc. may be laminated on the outer layer 2. Here, with respect to the body wall thickness T 1 of the composite pipe 1, the wall thickness T 2 of the spigot 6 and the wall thickness T 3 of the socket 5 are set to be large, that is, T 1 < T 2 ≒ T 3 . be. An O-ring 8 is disposed on the outer surface of the tip of the spigot 6 via an annular recess 7, and this O-ring 8 serves as a seal. Furthermore, two annular recesses 9 are formed on the outer surface of the spigot 6 at a predetermined distance apart from the position where the O-ring 8 is disposed, and the two annular recesses 9 are opposed to each other. , 2 on the inner surface of socket 5
A striped annular recess 10 is formed. An annular spring material 11 made of nylon, polyethylene, etc. is disposed between the opposing annular recesses 9 and 10. This annular spring material 11 has an inner ring portion 11A.
A cross section V in which the outer ring portion 11B and the outer ring portion 11B are connected and integrated.
The outer ring portion 11B is divided into a plurality of parts by slits 12 in the circumferential direction. The annular spring material 11 has a connecting portion 11C.
Further, the inner ring portion 11A is fitted into the annular recess 9, and the outer ring portion 11B is fitted into the annular recess 10 so that the inner ring portion 11A is positioned on the outer end side of the spigot 6.

れる。 When connecting the two composite pipes 1, first an O-ring 8 is placed in the annular recess 7 of the spigot 6, and annular spring members 11 are placed in both the annular recesses 9, 9, respectively. At this time, the annular spring material 11 is disposed by winding a tape-shaped material shown by solid lines in FIG. 2 into the annular recess 9 as shown by phantom lines in FIG. After that, the socket 6 is inserted into the socket 5, but the insertion is done through the outer ring part 11.
This is easy because B is elastically deformed, and the outer ring portion 11 is fully inserted.
B elastically returns to engage with the annular recess 10. When tensile force or bending force is applied between both composite pipes 1 in such a connected state, the wall thickness T 2 of the spigot 6 and the wall thickness T 3 of the socket 5 are larger than the body wall thickness T 1 . Therefore, even if the body section is stretched or bent, it will not occur at the socket 6 or the socket 5, and therefore the connection (engagement) via the annular spring material 11 will be maintained.

When tensile force or bending force is applied to the composite pipe, the body stretches or bends, but the socket and spigot do not change at all, so the connection via the annular spring material is ensured. be able to. This makes it possible to provide a connection structure that is strong against earthquakes.
