In addition, in the example shown in FIG. 8, the fiber reinforced resin layer E (7) is arrange | positioned also in the sequence direction both ends of the hollow structure segment 3 arranged in multiple numbers.

  In the configuration in which the fiber reinforced resin layer E (7) is arranged, the orientation angle of the reinforcing fiber e is set to an angle different from the orientation angle of the reinforcing fiber d in the fiber reinforced resin layer D (6). It is also possible to adopt a form. If comprised in this way, the boundary part which the hollow structure segment 3 mutually adjoins has the fiber reinforced resin layer D (6) and the fiber reinforced resin layer E (7) containing the reinforced fiber d and the reinforced fiber e of mutually different orientation angles. Therefore, it is possible to further improve the connection strength between the plurality of hollow structure segments 3, thereby further improving the rigidity of the entire water stop panel.

It is also possible to adopt a form. If comprised in this way, each hollow structure segment 3 can be reinforced and the connection intensity | strength between the some hollow structure segments 3 can also be improved, Thereby, the improvement of the intensity | strength and rigidity of the whole water stop panel is attained.

  As yet another embodiment, for example, as shown in FIG. 11, the plurality of hollow structure segments 3 are covered and covered with a fiber reinforced resin layer C (5) containing woven or knitted fibers. , A fiber reinforced resin layer F (8) including reinforced fibers f aligned in one direction is disposed on the inner surface of the fiber reinforced resin layer C (5), and the plurality of the fiber reinforced resin layers F (8) It is also possible to adopt a form in which the individual hollow structure segments 3 are covered and covered. If comprised in this way, it will become possible to improve the strength and rigidity of the fiber reinforced resin layers (5) and (8) covering the plurality of hollow structure segments 3, thereby improving the strength and rigidity of the entire waterproof panel.
