WOODEN MATTRESS FRAME BODY AND WOODEN MATTRESS CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To solve the problem of having a defect in conventional wooden mattress that can hardly be regarded as a construction method for restoring natural environment due to incapability of breaking stagnation and reproducing stagnation. SOLUTION: A triangular frame body from the top view is formed by overlapping the respective end parts of three wooden rods with one another to connect them, and filling lumps are disposed inside each frame body laid with one side continuously connected on the shore side, and in the recessed parts of a rugged part formed by the outer faces of the respective frame bodies. Alternatively, the frame bodies formed in triangular shape by overlapping the respective end parts of three wooden rods with one another to connect them are laid with one side continuously connected on the shore side while forming the rugged part with the outer surfaces of the frame bodies on the opposite side.
