Assembly of reinforced concrete slabs - has concrete topping entering spiral wire over hooked reinforcements at joints

摘要

Two identical slabs (1, 2) have lengthwise counter-braces and transverse bars (6), each of the bars ending in a protruding hook (7, 7a) bent upwards and turned towards the inside of the slab. The hooks belonging to two adjacent slabs are therefore back to back. Concrete (14) is poured onto these slabs. A wire (8) twisted into a spiral with its axis parallel to the joint (10) and its turns vertical is placed on the slabs in such a way that a part of each turn is in contact with the two adjacent slabs along the joint line, while the opposite part of the turn is above the hooks, this spiral binding above the joint a cylinder (9) of the concrete poured in situ.
