Abstract

PURPOSE: To obtain a compound tube having an improved strength by forming an FRP layer on the outer periphery of a resinous mortar layer and in contact with a part of a reinforcing iron bar embedded into the mortar layer.
CONSTITUTION: In the compound tube 1 comprising an intermediate layer 3 made of a reinforced mortar and an inner and an outer layer 2 and 4 made FRP layer, the FRP layer 12 of the outer layer 4 is in contact with a part of the reinforcing iron bar 6 embedded in the resinous mortar 11 of the intermediate layer 3. To obtain such a construction of the tube 1, a part of the reinforcing iron bar 6 to be embedded in the intermediate layer 3 is projected out of the layer 3 to contact with a frame, so that it appears on the layer 3 when the frame is removed after formation of the layer 3. Then the FRP layer 12 of the outer layer 4 is formed around the intermediate layer 3 and in contact with the projected part of the reinforcing bar 6.
