本発明は樹脂モルタルを中間層とした強化樹脂管状体の
成形方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for molding a reinforced resin tubular body using resin mortar as an intermediate layer.
従来、樹脂モルタルを中間層とした強化樹脂管状体を成

型する方法をとることがある。Conventionally, when molding a reinforced resin tubular body with a resin mortar as an intermediate layer, as described in Japanese Patent Publication No. 52-13822, synthetic resin-impregnated fiber material is wound around a rotating core metal in the axial direction of the core metal. The feeding inner layer is molded, synthetic resin mortar is wrapped around the outside of the inner layer to form an intermediate layer, and a fiber material impregnated with resin is wrapped around the outside of the inner layer to form an outer layer. A method of heating and curing and demolding may be used.

沢山入れようとすると落下しやす《、また管継手等の複
雑な形状をした管状体の成形においては合成樹脂モルタ
ルを適宜その形状に合せて中間層として入れることは困
難であるという欠点があった。However, with the conventional method as described above, if you try to put a lot of synthetic resin mortar in it, it tends to fall off (also, when molding a tubular body with a complicated shape such as a pipe joint, it is necessary to adjust the synthetic resin mortar appropriately to the shape). It had the disadvantage that it was difficult to include it as an intermediate layer.

特徴とする強化樹脂管状体の成形方法に存する。The present invention was made with the aim of eliminating the drawbacks of the conventional methods as described above, and the gist thereof is to provide an inner surface layer made of a reinforced molding material impregnated with resin on the outer peripheral surface of the core mold. A resin mortar is applied to the inner surface of the split outer mold in advance, and the surface of the resin mortar is shaped using a shaping mold that almost matches the outer surface shape of the inner surface layer. After the resin mortar coated on the inner surface layer has hardened to some extent, the split outer mold is removed to form an intermediate layer made of resin mortar, and an outer layer made of a reinforced molding material impregnated with resin is formed on the intermediate layer. The present invention relates to a method for molding a reinforced resin tubular body, which comprises integrally curing after forming a surface layer.
