Concrete form tie assembly for monolithic slabs bearing on masonry stem walls
First Claim
1. A tie assembly for connecting forms for cast-in-place concrete floor slabs to masonry stem walls, the tie assembly comprising:
- a retaining member configured to securely anchor to a stem wall;
an elongate extension member having a first end and a second end, the first end connected to the retaining member;
a tab connected to the second end of the extension member by a release mechanism, the tab having one or more slots for receiving a wedge stake, the wedge stake having a lower portion and an upper portion, the lower portion configured for insertion into one of the one or more slots of the tab and the upper portion configured for connection to the concrete form by a mechanical fastener having a tip; and
a reinforcement holder having a shaft and a clip member, the shaft attached to the tip of the mechanical fastener, and the clip member configured to receivably retain a concrete reinforcing member;
wherein the shaft of the reinforcement holder comprises a hollow recess for receiving the tip of the mechanical fastener, where the hollow recess has a first portion with a first diameter and a second portion with a second diameter, where the first diameter is larger than the diameter of the mechanical fastener, and the second diameter is slightly smaller than the diameter of the mechanical fastener such that the second portion is configured to snugly receive the tip of the mechanical fastener.

Abstract
A tie assembly for use during construction of monolithic cast-in-place concrete floor slabs bearing on a masonry stem wall. The tie assembly connects to one or more header blocks of the stem wall, and the tie assembly is configured to retain a concrete form member in place during the pour and curing period of the cast-in-place concrete. The tie assembly has a removable tab member with one or more slots for receiving a wedge stake, which braces the form member against lateral forces caused by the wet concrete. A mechanical fastener is driven through an upper portion of the wedge stake and concrete form, and the insertion tip of the mechanical fastener connects to a reinforcement holder for retaining a reinforcing member in place.
