Post-tension concrete leave out splicing system and method

摘要

Devices, systems, and methods for constructing post-tensioned concrete slabs in a new floor construction that has a reduced gap distance between the slabs. The devices, systems, and methods can improve project construction time by reducing the time delay in accessing the floor underneath the slabs due to safety and/or weather conditions.

主权项

1. A concrete floor construction, comprising:
a first post-tensioned concrete floor slab, a second post-tensioned concrete floor slab, and a cavity-forming device, said first post-tensioned concrete floor slab and said second post-tensioned concrete floor slab having respective upper surfaces that are generally aligned, said first post-tensioned concrete floor slab including a plurality of first rebars installed therein, said first post-tensioned concrete slab being post-tensioned in at least a direction substantially parallel to said plurality of first rebars, said second post-tensioned concrete floor slab including a plurality of second rebars installed therein, said second post-tensioned concrete slab being post-tensioned in at least a direction substantially parallel to said plurality of second rebars, said first post-tensioned concrete floor slab and said second post-tensioned concrete floor slab being separated by a gap so that the concrete material of said first post-tensioned concrete floor slab is not in contact with the concrete material of said second post-tensioned concrete floor slab, and said cavity-forming device forming a cavity, said cavity-forming device being installed in said first post-tensioned concrete floor slab, wherein said cavity contains a portion of one of said second rebars.
