Filed:

Nov 20, 2001

Appl. No.:

09/989612

Inventors:

Bryant Zavitz - Dunwoody GA

Assignee:

Tindall Corporation - Conley GA

International Classification:

B60P 708

US Classification:

410 91, 410 90, 410 94, 410 35

Abstract:

A rail car transporting system is used to transport relatively heavy structures by rail car, particularly prefabricated concrete structures. At least one pair of portable retaining devices are configured to retain the structure on the rail car generally at opposite longitudinal sides thereof. Each retaining device includes a base member positionable under the structure with a vertically extending boss member configured on the base member. This boss member has a shape and size so as to fit into a recess defined in the bottom of the structure. Each of the retaining devices also includes at least one securing device that is configured to secure the retaining device to the rail car such that the structure is retained on the rail car by engagement of the boss members within the recesses.

Abstract:

Disclosed are apparatus and corresponding methodology for providing a base support, such as including concrete, and used such as for a wind-driven generator. Precast concrete cylinders are stacked in place upon a platform that may be partially precast and partially cast in place during assembly and supported, in certain embodiments, by plural concrete legs, the other ends of which are supported on a unitary or subdivided concrete foundation. In other embodiments, the platform may be supported by ribbed concrete panels. The concrete cylinders are glued together using an epoxy and then secured by an internal vertical post tension system extending from the platform to the upper most cylinder. Different types of concrete are used between upper and lower sections of the stacked cylinders. The lower section uses reinforced concrete while the upper section used ultra high performance fiber reinforced concrete.

Assignee:

ZMZ PRECAST, INC. - Atlanta GA

International Classification:

E04C 5/08

US Classification:

522236

Abstract:

A precast concrete I-deck is provided. The I-deck comprises a bottom slab member, or soffit, with a plurality of I-beams evenly spaced along the width of the soffit, the I-beams being parallel to each other along the length of the soffit. The I-deck has diaphragm members on either end, perpendicular to the I-beams Pre-stress wires are embedded in the soffit and I-beams between the diaphragms. The spaces between the I-beams may be used to run wiring, plumbing, or ducts, or they may be filled with a filling material. The I-deck may be used in bridging and support systems for roofing or flooring.

Abstract:

Pre-cast concrete stairs, molds for making pre-cast concrete stairs, and methods of casting pre-cast concrete stairs are provided. The stair is constructed with two beams that are cast with the stair steps as an integral monolithic structure. One of the beams (integral down edge beam) projects below the steps on one side, and the other (integral up edge beam) projects above the steps on the other side. The weight of the stairs and the weight of traffic on the steps creates compression on the tops of the integral down edge beam and integral up edge beam, and tension on the bottoms of the integral down edge beam and integral up edge beam, which enhances the combined strength of the beams. The asymmetric orientation of the members creates a stronger cross-section than if the beams were in the same plane horizontally, allowing greater load handing capability. Lightweight steps are suspended between the two beams.
