Abstract
A cage frame for shore protection and so on with improves durability, the construction/execution on site can be easily performed, can easily create the best environment for organism to live and can be effectively used as a gathering place for fish. The hollow framing is formed by joining many plane frames with many openings on each and then filled with stones and/or broken stones. Each plane frame is formed by cast iron with joint structures integrally formed therewith. The joint structures are joined together to form the hollow framing on site.
Claims14
An assembly for retaining rocks, comprising:
- a plurality of interconnected generally planar frame members, said frame members formed from cast iron in a unitary fashion and having an upper rail, a lower rail, at least one cross-member disposed between said upper rail and said lower rail, and end joint sections;
- a plurality of fill spaces defined by said frame members for retaining rocks;
- wherein each joint section of said frame members defining said fill spaced is joined to at least one other joint section of another frame member;
- and
- wherein said joint sections include a pointed central tine aligned coplanar with said upper rail, first and second outer tines extending parallel to said central tine and equally disposed on opposite sides thereof, and an embossment on said central tine opposite each of said outer tines, each of said outer tines forming a hook shaped cavity with said central tine and the corresponding embossment.
An assembly for retaining rocks, comprising:
- a) a plurality of interconnected generally planar frame members, said frame members formed from cast iron in a unitary fashion and having an upper rail, a lower rail, at least one cross-member disposed between said upper rail and said lower rail, and means for joining said frame member to at least two other frame members;
- b) a plurality of fill spaces defined by said frame members for retaining rocks,
- c) wherein each joint section of said frame members defining said fill spaced is joined to at least one other joint section of another frame member via said joint means.
An assembly for retaining rocks, comprising:
- a plurality of interconnected generally planar frame members, said frame members having an upper rail, a lower rail, and integral end joint sections, said joint sections comprising a pointed central tine aligned coplanar with said upper rail, first and second outer tines extending parallel to said central tine and disposed on opposite sides thereof;
- a plurality of fill spaces defined by said frame members for retaining rocks;
- and
- wherein each joint section of said frame members defining said fill spaced is joined to at least one other joint section of another frame member.
An assembly for retaining rocks, comprising:
- a plurality of interconnected generally planar frame members, said frame members formed from cast iron in a unitary fashion and having an upper rail, a lower rail, at least one cross-member disposed between said upper rail and said lower rail, and end joint sections;
- a plurality of fill spaces defined by said frame members for retaining rocks;
- a plurality of joint members, each joint member in wedged engagement with corresponding end joint sections of at least two different frame members so as to form a joint therebetween, each of said joint members being generally tapered in a first direction and comprising first and second catch portions disposed proximate respective ends of said joint member and protruding generally perpendicular to said first direction, said first and second catch portions engaging respective end joint sections of different frame members;
- and
- wherein each end joint section of said frame members defining said fill spaced is joined to at least one other joint section of another frame member.
