BUILT-UP FRAME FOR SOIL-ROCK FILLING

摘要

PROBLEM TO BE SOLVED: To enable an assembly on the outside of a field, and to inhibit a deformation in the case of a disposal. SOLUTION: A built-up frame for a soil-rock filling has a plurality of side-section male joints mounted on the side face of an adjacent one frame board and a plurality of side-section female joints fitted to be engaged with the side-section male joints on the side face of the other frame board. The side-section male joint is composed of a male joint body consisting of a rod-shaped body having a rectangular longitudinal section, a first engaging section projected and formed to the front-end outer side face of the male joint body and inclined in a wedge shape in a lower section in the rectangular longitudinal section and a second engaging section being projected and formed to an intermediate section in the height direction of the inner side face of the male joint body and having the rectangular base section of the longitudinal section having a trapezoidal front end. The side-section female joint is composed of a sideways L-shaped female joint body opened on the side end side of the frame board, the first engaging section being formed in response to the first engaging section on the internal surface of the female joint body and consisting of a U-shaped cross sectional groove and the second engaging section consisting of a rectangular recessed section formed in response to the second engaging section on the side face of the frame board opposed to the internal surface of the female joint body.
