US 5,625,993 A · Concrete structure having load transferring insert and method for making same

Abstract

A support member for a concrete structure comprises a Y-shaped hollow insert defining an internal channel having a Y-shaped cross-section. A V-shaped nut is inserted in V-shaped portion of the internal volume and end caps are placed over the ends of the insert to fully enclose the internal volume. The insert is then placed within a form for a concrete structure such that the base surface of the Y-shaped insert will be coplanar with a surface of the concrete after the concrete has been poured into the form and set. The base wall of the insert is then removed, thus exposing the internal volume. The distal end of a bolt can be inserted into the insert and fixed to the nut. The proximal end of the bolt extends out of the insert and beyond the surface of the concrete to be attached to equipment or another structure which is to be supported on the concrete structure.

Dependent claims

A concrete structure for supporting an object thereon, said structure having a first surface and comprising;

a support member substantially embedded within said concrete structure, said support member comprising, a longitudinal member generally perpendicular to said first surface and having a first end extending from said first surface, and a load transferring member connected to said longitudinal member, said load transferring member having a load transferring surface oblique to said first surface, and
an insert disposed in said concrete structure and having an opening coplanar with said surface of said structure and the remainder of said insert being embedded within said concrete structure, said insert having an interior volume with first and second contiguous portions, said first portion sized and shaped to accept said load transferring member in a first orientation and said second portion sized and shaped such that said load transferring member does not fit into said second portion when in said first orientation and said longitudinal member does fit within said second portion, said support member being disposed in said insert with said load transferring member in said first portion in said first orientation, whereby said support member can be attached to said object and a load of said object is transferred through said concrete.

A concrete structure for supporting an object thereon, said structure having a first surface and comprising;

a support member substantially embedded within said concrete structure, said support member comprising a longitudinal member generally perpendicular to said first surface and having a first end extending from said first surface and further comprising a load transferring member connected to said longitudinal member, said load transferring member having a load transferring surface oblique to said first surface, and
an insert disposed in said concrete structure and having a first opening coplanar with said surface of said structure and the remainder of said insert being embedded within said concrete structure, said insert having an interior volume with first and second contiguous portions, said first portion sized and shaped to accept said load transferring member in a first orientation and said second portion sized and shaped such that said load transferring member does not fit into said second portion when in said first orientation and said longitudinal member does fit within said second portion, said support member being disposed in said insert with said load transferring member in said first portion in said first orientation, whereby said support member can be attached to said object and a load of said object is transferred through said concrete,
wherein said insert has a second opening sized and shaped to accept said load transferring member into said first portion in said first orientation, said insert further comprising an end cap sized and shaped to cover said second opening.

A method of fabricating a concrete structure having a support member embedded within the concrete of said structure for supporting an object on said concrete structure with a load of said object transferred through said concrete, said method comprising the steps of;

(1) providing a form defining a shape of said concrete structure,
(2) providing a support member comprising a longitudinal member and a load transferring member connected to said longitudinal member, said load transferring member having a load transferring surface,
(3) providing an insert, said insert comprising a first opening and an interior volume, said interior volume having first and second contiguous portions, said first portion sized and shaped to accept said load transferring member in a first orientation and said second portion sized and shaped such that said load transferring member does not fit into said second portion when in said first orientation and said longitudinal member does fit within said second portion, said support member being disposed in said insert with said load transferring member in said first portion in said first orientation,
(4) placing at least said load transferring member of said support member in said insert with said load transferring member in said first orientation in said first portion,
(5) positioning said insert in said form such that said insert and support member can be substantially embedded within said concrete structure with said longitudinal member generally perpendicular to a first surface of said concrete structure and with a first end of said longitudinal member extending from said first surface and said load transferring surface oblique to said first surface when said concrete structure is poured and set in said form, and
(6) pouring concrete into said form such that no concrete enters said interior volume of said insert and so that said first surface of said concrete structure is formed coplanar with said opening of said insert.
