Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a decorative wall board in a steel sheet pile revetment structure.

"Prior art" Conventionally, a U-shaped steel sheet pile is assembled by assembling by mounting the fittings for fitting in the longitudinal central direction of the back surface of the web of each U-shaped sheet pile on the bank side of the sheet pile wall. Provided in each of the fittings for fitting, each side end bent portion of the adjacent decorative shielding plate is fitted and the back surface of each decorative shielding plate is attached to the water area side of the steel sheet pile wall. A U-shaped steel sheet pile that is brought into contact with the surface of a web is disclosed in Japanese Utility Model Laid-Open No. 62-89324.

"Problems to be solved by the invention" By the way, as described in the above-mentioned published utility model gazette, each side of the adjoining makeup shield plate is located in the longitudinal central direction of the back surface of the web of each U-shaped steel sheet pile on the shore side. The cost of the U-shaped steel sheet pile itself is significantly increased by providing the mounting metal fitting into which the end bent portion is inserted.

Also, if the intervals between the U-shaped steel sheet piles are not uniform, it is completely impossible to insert the bent portions on both sides of each decorative shield into the mounting brackets of each U-shaped sheet pile on the shore. However, there is a problem in that each U-shaped steel sheet pile must be accurately placed.

It is an object of the present invention to provide a decorative wallboard for a steel sheet pile revetment structure that is intended to solve the above-mentioned conventional problems.
