Benefits of technology

[0010]Constructing the deck by applying high tension to the steel wire strands before and during the curing of the concrete produces a monolithic structure of great strength and resistance to cracking. The high-tension steel wires help keep the concrete compressed throughout its life. These wires also reduce deflection for any length of span.

Problems solved by technology

Solid concrete slabs, or decks, used for this purpose may be heavy, making them difficult to handle or to lift up for installation on higher floors.
Such decks may also exhibit poor sound and heat insulating qualities.
Such slabs, or decks, may tend to crack over time and become weak or useless.
Water may enter the cracks and damage any steel reinforcing material.

Embodiment Construction

[0017]I-decks, systems using I-decks, and methods of forming I-decks are provided, and several exemplary embodiments will be discussed in detail. Embodiments of an I-deck are relatively lightweight, making them easy to handle and install when used in building construction. They may also have enhanced sound and heat insulating properties. Other embodiments may provide a low-cost alternative to solid concrete slabs or pre-cast deck systems. The pre-cast I-decks of this invention have greatly improved strength because the high tension steel wires are stressed under high tension while the concrete is being poured and cured which greatly helps to keep the deck as a monolithic structure. This prevents cracking because the high-tension wires compress the concrete between the two ends of the deck.

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.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of and priority to U.S. Provisional Application 60 / 862,338, filed on Oct. 20, 2006, which is incorporated herein by reference.BACKGROUND[0002]1. Technical Field[0003]This disclosure generally relates to reinforced pre-cast concrete I-beam decks, bridging and support systems that have pre-stressed steel wire strands as reinforcing material.[0004]2. Description of the Related Art[0005]Pre-cast concrete has many applications in the construction industry. Concrete that is precast tends to be of higher quality than concrete that is cast and cured on-site, as precasting may be done under controlled conditions. Pre-cast concrete slabs may be used in bridging and support systems, to support flooring or roofing in a building. Solid concrete slabs, or decks, used for this purpose may be heavy, making them difficult to handle or to lift up for installation on higher floors. Such decks may also exhibit poor sound an...
