International Classification:

E04B 900

US Classification:

521261, 52217, 5220456, 2481882

Abstract:

A shim assembly comprises a first shim piece having a generally planar body and a plurality of spaced apart projections extending upwardly therefrom.

Assignee:

Deslauriers, Inc. - Bellwood IL

International Classification:

E04C 516

US Classification:

52300, 52301, 52698, 256DIG 6

Abstract:

Broadly, there is disclosed herein in accordance with a first aspect of the invention a safety system for use with linearly arranged reinforcement bars. The safety system includes a plurality of safety covers and a plurality of adapters. Each safety cover includes a cover plate and a collar operatively associated with and extending downwardly from the cover plate for mounting to an upper end of a reinforcement bar. Each adapter has a center section and opposite upwardly turned side sections defining a channel. The center section is adapted to removably receive one of the safety covers to secure the adapter to the reinforcement bar. The channel receives an elongate body extending between two or more of the adapters on linearly arranged reinforcement bars.

Assignee:

Deslauriers, Inc. - Bellwood IL

International Classification:

G01N 300

US Classification:

73803, 73788

Abstract:

An unbonded capping system is provided for compression testing of grout samples in the form of rectangular prisms. The capping system comprises first and second retaining cups comprising metal blocks each having opposite parallel planar surfaces. A first of the planar surfaces is engagable by a test platen, in use. A second of the planar surfaces has a rectangular cavity for receiving one end of the grout sample. First and second rectangular compression pads each have a hardness in the range of about 50-70 durometer. The compression pads are of a size slightly smaller than a size of the rectangular cavities to be received therein to distribute a test load from the test platens to the grout sample.

International Classification:

G01N003/00

US Classification:

73803

Abstract:

An unbonded capping system for compression testing of concrete cylinders comprises first and second retaining cups comprising metal blocks each having opposite parallel planar surfaces. A first of the planar surfaces is engageable by a test apparatus, in use. A second of the planar surfaces has a cylindrical cavity of a first select diameter for receiving one end of the concrete cylinder. First and second cylindrical compression pads are each to be received in one of the retaining cup cavities to abut an end of the concrete cylinder, in use. The compression pads are of a second select diameter smaller than the first select diameter of the cavity to define a circumferential space therebetween. Nubs are provided for gripping the cavity to prevent the compression pads from falling out of the cavities.

International Classification:

G01N 3/00

US Classification:

73803, 73760

Abstract:

A biodegradable test cylinder mold is used for testing concrete specimens. The mold comprises a cylindrical wall connected to a bottom wall to define a hollow, unitary cylindrical container for receiving concrete to form a test specimen. The cylindrical container is formed of a biodegradable material comprising corn starch or a blend of corn starch and plastic.

Inventors:

Gary Workman - Bellwood IL, US

International Classification:

G01N033/00

US Classification:

073/866000

Abstract:

A concrete test specimen apparatus includes a test cylinder having a cylindrical side wall closed by a bottom wall to define an interior space accessible through a top opening. A rectangular liner in the interior space covers an inside of the cylindrical side wall. When the interior space is filled with a specimen of concrete, the liner is disposed between the specimen and the side wall to enable sliding of the specimen out of the interior space.
