A corrosion-resistant layer 2 is laminated on the inner surface. A flange 3 is attached to the outer periphery of the end of the resin pipe 1, and this flange 3 is formed from a mortar body 4 and a plurality of layers of cloth-like reinforcing fibers 5 embedded in this body 4. The reinforcing fibers 5 are arranged linearly in the direction along the tube axis 6. In the figure, 7 indicates a corrosion-resistant resin layer that reinforces the interface between the flange 3 and the resin pipe 1, and 8 indicates a through hole through which a connecting bolt can be inserted.

応力が弱かつた。 According to such a conventional structure, when looking at one layer of cloth-like reinforcing fibers 5, for example, tensile force from both sides
Forces F 3 , which are strong against F 1 and F 2 but in different directions between the layers ,
The interlayers will be easily sheared when F 4 acts. In other words, conventional materials were extremely susceptible to shearing forces. Moreover, since the main body 4 is made of mortar, the surface stress is low.
本考案の目的とするところは、剪断力ならびに
表面応力に強い樹脂管の端部フランジ構造を提供
する点にある。 An object of the present invention is to provide an end flange structure for a resin pipe that is resistant to shearing force and surface stress.

る。 In order to achieve the above object, the end flange structure of the resin pipe in the present invention is a flange formed at the end of the resin pipe, and is composed of an outer mortar body and an inner fiber-reinforced resin skin. The main body has a plurality of layers of cloth-like reinforcing fibers extending along the tube axis, and these cloth-like reinforcing fibers are formed in a wave shape with respect to the tube axis by a wire member. .

に巻き付けるが如くして締付け巻回される。 An embodiment of the present invention will be described below with reference to FIGS. 3 to 5. That is, the flange 3 is formed of a mortar body 4 and a fiber-reinforced resin skin body 9 provided inside the mortar body 4. This skin 9 is an annular thin plate, and its outer end is perpendicular to the tube axis 5, and its inner end is curved and runs along the outer surface of the resin tube 1. Further, the skin body 9 is manufactured by incorporating glass fibers (chopped strands, rovings, etc.) into resin. The mortar body 4 is made of sand and resin,
The ratio (weight%) is when sand is 100% wt.
The resin content is 20-40%wt. Also 100% wt of sand
is 60% wt of large silica sand (silica sand No. 2 to 4), 30% wt of medium silica sand (silica sand No. 5 to 8), and small silica sand (tankal).
is mixed with a 10% wt distribution. The cloth-like reinforcing fibers 5 are tightened with a wire member 10 made of piano wire, glass fiber wire, etc. to form a wave shape with respect to the tube axis 6. Note that the wire member 10 is tightened and wound around the tube axis 6.
上記構成の本考案における樹脂管の端部フラン

きる。 According to the end flange structure of the resin pipe according to the present invention having the above configuration, the following effects can be expected.
In other words, because the cloth-like reinforcing fibers embedded in multiple layers are wavy with respect to the tube axis, the shear resistance can be much higher than that of conventional straight fibers, and the lamination of the fiber-reinforced resin main body Therefore, strong surface stress can be expected.
