PURPOSE: To facilitate construction by forming a slope frame into a frame condition originally for laying the frame accurately only by vertical and horizontal joint work. ;CONSTITUTION: A slope frame unit 10 is formed as a frame body in a rectangular condition, and plural bolt insertion holes 12 which go through the inside and outside of the slope frame unit 10 are drilled at the prescribed positions of the respective edges 10a of the slope frame unit 10. Anti-corrosion bolts 14 are inserted there, and nuts 16 are screwed in the projection ends to joint the adjacent slope frame units 10 with each other. A net for reinforcing the banking is stopped against the slope frame unit 10 by the anti-corrosion bolts 14, and is fixed by friction force which effects on the joint surface between the slope frame units 10.;COPYRIGHT: (C)1993,JPO&Japio
