題点があつた。"Problems to be Solved by the Invention" However, when using the above-mentioned conventional composite members in offshore structures, etc.,
The outer panel of the steel shell is exposed to direct contact with seawater and salt-containing outside air, and heavy corrosion protection must be applied to protect it from corrosion, which increases the cost of painting and increases the cost of painting. This causes delays in the construction period, and in addition, regular maintenance (repainting) is required, increasing maintenance costs.
In addition, underwater, where maintenance is impossible,
There were problems such as the need to make the steel plate thicker than necessary or use metal materials that are resistant to corrosion in consideration of corrosion allowances, etc., which caused an increase in construction costs.

There is no need to apply corrosion protection, and there is no need to perform regular maintenance. In addition, since the outer panel is made of fiber-reinforced plastic and the ribs or end plates are integrally formed with the outer panel, attaching ribs or end plates to conventional steel plates requires welding, etc. In contrast, the composite member itself is easier to manufacture. Furthermore, since the rib or the end plate is provided with a connecting portion with the inner plate, connection with the inner plate is facilitated.

わめて容易になる。"Effects of the Invention" As explained in detail above, according to the composite member of the present invention, fiber-reinforced plastic is used for at least the outer plate of the steel shell, so even when used in offshore structures, the composite member can be used in marine structures. The components do not corrode due to salt, so there is no need for corrosion protection or periodic maintenance, and it is possible to shorten the construction period, reduce construction costs, and reduce maintenance costs. In addition, when attaching ribs or end plates to conventional steel plates, unlike conventional methods such as welding, the outer plate is made of fiber-reinforced plastic, and the ribs or end plates are integrally formed on the inner surface of the outer plate. Therefore, the manufacturing time of the composite member itself can be shortened, and the labor required for its manufacturing can be reduced, resulting in a significant reduction in cost. Furthermore, since the ribs or end plates have a connecting portion with the inner plate, the connection with the inner plate can be easily performed using this, and therefore the manufacture of the composite member is extremely easy.
