Four channel sections will be placed, according to the Technical Documentation, centered about the floor depth.
The anchorage shall be incorporated to the support in the shop.
The sections will be welded to each other and to the support all around the contact perimeter, with a 5/16 in. thick weld.
At the joint, the interrupted channel will have a continuous cover plate of steel with a total area matching that of the top flange of the section, welded all around with a 3/16 in. thick weld.
A spiral of W8 flat wire conforming to ASTM A 82, with a 4 in. spacing, shall be placed in both arms of the steel anchorage.
The recommended crosspieces are for building floors with conventional live loads and reasonably balanced spans. In all other cases an individual study is required.
