Abstract
A wall is formed of large, preformed structural slabs containing horizontally extending reinforcing members. The reinforcing members are made interlocking so that adjacent slabs in the same course are locked together horizontally. The slabs are placed in the wall vertically aligned, so that the reinforcing members and locking means (which extend outside the preformed concrete slabs) of slabs of successive courses can be welded together, giving a skeleton of steel which imparts great strength and earthquake resistance to the structure. Preferably, the structure is a silo and the slabs are arcuate.
Claims10
A wall comprising a plurality of concrete slabs, joined together in successive courses, each of said slabs comprising a plurality of vertically spaced horizontally extending reinforcing members and a vertically extending connecting member at each end of each of said slabs, said connecting members being welded to said reinforcing members and extending the entire distance from top to bottom of each of said slabs, said connecting members having interlocking portions positioned completely outside the concrete of said slabs, extending the full length of said connecting members and being straight and uniform in cross section throughout their length, the connecting members of adjacent slabs in the same course being interlocked, the connecting members of slabs in successive courses being aligned and in direct contact with each other and welded together, whereby said connecting members and said reinforcing members form a complete skeleton for said wall, the spaces between said slabs and said interlocking members being filled with non-shrink grout.
A structural unit for a wall comprising a concrete slab having a height many times its thickness and a length several times its height, longitudinal reinforcing members vertically spaced from one another within said slab, connecting members at each end of said slab extending vertically the entire height of said slab and welded to each of said reinforcing members, the connecting members of each slab having complementary interlocking portions so that successive slabs of a given course can be locked together, said interlocking portions being positioned entirely outside the concrete of said slab so that when successive slabs are locked together there is a space between the ends of the concrete, said interlocking portions extending the full length of said connecting members and being straight and uniform in cross section throughout their length.
A method of erecting a wall comprising forming concrete slabs, each of said slabs being several feet in height, several inches in thickness and several times as long as high, and comprising longitudinal reinforcing members vertically spaced from one another within said slab, connecting members at each end of said slab extending vertically the entire height of said slab and welded to each of said reinforcing members, the connecting members of each slab having complementary interlocking portions so that successive slabs of a given course can be locked together, said interlocking portions being positioned entirely outside the concrete of said slab so that when successive slabs are locked together there is a space between the ends of the concrete, said interlocking portions extending the full length of said connecting members and being straight and uniform in cross section throughout their length, transporting said slabs to the point of erection of the wall, lifting said slabs by power and setting them in courses, sliding the interlocking portions of said connecting members into interlocking relationship, the connecting members of all of the courses being aligned, welding said connecting members together and filling the spaces between the slabs and within said connecting members with non-shrink grout.
