Abstract (en)
[origin: CA1218241A] A concrete structure comprises a rigid threedimensional lattice of concrete bars which are interconnected at nodes. The lattice is constituted by an assembly of prefabricated cast blocks, in which each block comprises a node and arms radiating from the node. Each arm has at least one longitudinal socket with an opening in a free end of the arm, and the arms of two blocks are assembled in aligned end-to-end pairs to constitute the bars of the lattice. The sockets of assembled arms are in alignment and contain a common metal reinforcing member, and the junction zone of the arms is surrounded by a clamping sleeve, with the sockets being filled with hardened mortar. The lattice is prestressed by prestress cables passing outside the bars of the lattice and fixed to some nodes of the lattice.
