Abstract
A connection sleeve for a cast-in-place anchor. The cast-in-place anchor including a suspension plate having a threaded opening. The cast-in-place anchor also including an externally threaded rod with a head. The threaded rod threadably connected to the suspension plate so that the rod and plate are perpendicular. A sleeve between the rod and plate allows the rod to be securely connected to the plate by simply urging the rod axially toward and into the sleeve to securely lock with and engage with the plate. The assembly resulting in an X shaped cast-in-place anchor assembly.
Claims13
A cast in place anchor assembly for securement to metal decking in a concrete structure, the assembly comprising:
- an elongate threaded anchor including a head at a first end and an externally threaded portion;
- and
- a connection sleeve, the connection sleeve being internally threaded for threadably receiving the externally threaded portion, the connection sleeve further including an external locking portion, the external locking portion including a flexible securement portion;
- a suspension plate for spanning two peaks of the metal decking, the suspension plate including a sleeve opening;
- wherein the sleeve opening is sized to receive the external locking portion so that the external locking portion is lockably securable to the connection sleeve in the sleeve opening via the flexible securement portion;
- and
- wherein the flexible securement portion has a flexible locking member which has a first radius which is larger than the sleeve opening and which flexes to a smaller radius during insertion of the connection sleeve into the sleeve opening and which flexes back to a size larger than the sleeve opening upon a complete insertion to lock the connection sleeve to the suspension plate.
A method of assembling a cast in place anchor for securement to metal decking in a concrete structure, the method comprising the steps of:
- providing an elongate threaded anchor including a head at a first end and an externally threaded portion, the externally threaded portion having a longitudinal axis;
- providing a connection sleeve, the connection sleeve being internally threaded for threadably receiving the externally threaded portion, the connection sleeve further including an external locking portion, the external locking portion including a flexible securement portion or an externally threaded portion;
- providing a suspension plate for spanning two peaks of the metal decking, the suspension plate including a sleeve opening and having a longitudinal axis in an elongated direction;
- threading the externally threaded portion of the elongate threaded anchor into the internal thread of the connection sleeve;
- inserting the flexible securement portion into the sleeve opening until the external locking portion is secured to the sleeve opening and the elongate threaded anchor is secured to the suspension plate.
