Description

[Detailed description of the invention] The invention includes a peripheral outer wall layer made of film or uncured resin;
The present invention relates to a composite structure comprising an intermediate layer made of an uncured resin and disposed between these outer wall layers and containing a curing accelerator.

For example, conventional methods for constructing offshore structures include sinking structures manufactured on land and cement methods using seawater; however, methods other than such cement methods,
For example, it is difficult to work on structures made of steel or resin underwater, so the above-mentioned land-based manufacturing method has to be adopted.

In particular, large resin-based structures cannot be used as offshore structures because they cannot be bonded (connected), hardened, or deformed underwater.

The present invention proposes a composite structure that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

That is, as shown in FIG. 1, the present invention includes a peripheral outer wall layer 1.2 made of a thermoplastic resin film or a semi-cured resin, and a layer disposed between these outer wall layers 1 and 2 and containing a curing accelerator or stabilizer. Composite structure 4 consisting of an intermediate layer 3 made of uncured resin
Then, an elastically deformable shape stabilizing material 5 made of, for example, a wire mesh, and a strong pressure (2 to 100 kg/cm) are applied to the intermediate layer 3.
”) It contains a large number of hardened balls 6 that break under the ball.

Note that cutter-shaped reinforcing fibers 7 are mixed in the intermediate layer 3, and a thermoplastic resin is used as the resin.

As shown in FIG.
The distance between the outer surfaces of 2, that is, the thickness L, is kept constant,
Therefore, as shown in FIG. 2, for example, one of the outer wall layers 1
When an external pressure W is applied from the side to reduce the thickness β, the shape stabilizing material 5 is compressively deformed, and the hardening ball 6 is broken by the pressure, and the hardening agent flows into the intermediate layer 3.

Thereafter, by releasing the external pressure W, the shape stabilizing material 5 is restored to its original thickness L, as shown in FIG. 3, and in this state, the intermediate layer 3 is gradually hardened.

According to the present invention described in the examples above, by applying external pressure to the intermediate layer, the hardened sword ball is destroyed and the curing agent flows into the uncured intermediate layer, thereby curing the intermediate layer. can.

Moreover, this hardening occurs when the shape stabilizer is restored to its pre-pressure shape when the external pressure is released, and when the shape stabilizer is maintained in the deformed state by resisting the shape stabilizer. It is done quickly.

Therefore, large marine structures made of resin can be easily constructed under the sea, thereby expanding the scope of use of resin.
