Abstract

A cast-in-place anchor and method of securing it to a wooden form board. Such cast-in-place anchors include a body defining a cavity and having a base for positioning the body on a wooden form board. The body being securable to the wooden form board by at least one fixing member. An opening is disposed in the base in communication with the cavity and a plurality of additional openings are in the body in communication with the cavity. A threaded member is provided in the cavity. A support member is also provided in the cavity for supporting the threaded member and for restricting the ingress of wet concrete through the additional openings into contact with the threaded member in use. The anchor is configured such that after concrete pouring, concrete setting, and form board removal, a threaded rod can be inserted into the opening in the base of the body.

First claim

The invention claimed is:

1. A cast-in-place anchor comprising:
a body defining a cavity and having a base for positioning the body on a wooden form board, the body being configured to be secured to the wooden form board by at least one fixing member;
an opening in the base of the body in communication with the cavity;
a threaded member provided in the cavity;
a support member also provided in the cavity for supporting the threaded member;
wherein the anchor is configured such that after concrete pouring, concrete setting and form board removal in use, a threaded rod can be inserted into the opening in the base of the body, past the support member and into threaded engagement with the threaded member for suspending a load from the anchor;
wherein the body comprises a plurality of separable clam shell body sections which cooperate to define the cavity and at least one nail guide for receiving a nail to secure the anchor to the wooden form board.

2. The cast-in-place anchor of claim 1 , wherein each said clam shell body section includes engagement surfaces aligned along an upwardly extending direction.

3. The cast-in-place anchor of claim 1 , wherein each said body section is identical.

4. The cast-in-place anchor of claim 1 , wherein each said body section comprises at least one set of guide members which are configured to interlock with the guide members of another said body section to form said nail guide.

5. The cast-in-place anchor of claim 4 , wherein each said nail guide is configured such that a nail received thereby in use restricts the respective body sections forming the nail guide from separating while securing the anchor to the wooden form board.
