Parking deck connecting system
View Patent ↗A connecting system for connecting concrete beams of a parking structure including a pair of concrete beams and a plurality of spring-like connectors connected between the pair of concrete beams. The concrete beams are each provided with an aperture and the spring-like connector is in a form of a pre-formed carbon fiber bundle or metal and has opposite ends that are secured in the apertures in the concrete beams by an adhesive.
1. A connecting system for connecting concrete beams of a parking structure, comprising:
a pair of concrete beams and a plurality of spring-like one-piece, arch shaped connectors connected between the pair of concrete beams, wherein the concrete beams are each provided with a plurality of apertures provided in a lower surface of the concrete beams and the plurality of one-piece, arch shaped connectors have an intermediate portion and a pair of opposite ends wherein the opposite ends are secured in the apertures in the concrete beams by an adhesive, and wherein the intermediate portion of the arch shaped connectors extend external to and below the pair of concrete beams.
2. The connecting system according to claim 1 , wherein the spring-like one-piece, arch shaped connectors are pre-formed from carbon fibers.
3. The connecting system according to claim 2 , wherein the carbon fibers are coated with a hardenable material.
4. The connecting system according to claim 1 , wherein the spring-like one-piece, arch shaped connectors are made from metal.
5. The connecting system according to claim 1 , wherein the spring-like one-piece, arch shaped connectors are formed from round carbon fiber bundles that have a cross-sectional diameter and length that provide for controlled relative movement of the concrete beams.
6. The connecting system according to claim 1 , wherein the plurality of apertures are parallel to one another.
7. A connecting system for connecting concrete beams of a parking structure, comprising:
a pair of adjacent double tee concrete beams; and
a plurality of spring-like one-piece, arch shaped connectors pre-formed from carbon fibers and having a pair of ends that are each connected to a bottom surface of a respective one of the pair of adjacent double tee concrete beams wherein an intermediate portion of the spring-like one-piece, arch shaped connectors extends below the bottom surface of the pair of adjacent double tee concrete beams.
8. The connecting system according to claim 7 , wherein the carbon fibers are coated with a hardenable material.
9. The connecting system according to claim 7 , wherein the pair of adjacent double tee concrete beams each include a plurality of parallel apertures provided in a lower surface and each of the plurality of spring-like one-piece, arch shaped connectors include a pair of legs received in the apertures in each of the adjacent double tee concrete beams.
10. The connecting system according to claim 7 , wherein the spring-like one-piece, arch shaped connectors are formed from round carbon fiber bundles that have a cross-sectional diameter and length that provide for controlled relative movement of the concrete beams.
11. The connecting system according to claim 7 , wherein the spring-like one-piece, arch shaped connectors include ends that are connected to the concrete beams by bolts.
12. The connecting system according to claim 7 , wherein the pair of ends are connected to the concrete beams by an adhesive.
13. The connecting system according to claim 7 , wherein the spring-like one-piece, arch shaped connectors include the pair of ends each having a mounting plate with at least one bolt hole for securing the spring-like connectors to the concrete beams.
14. The connecting system according to claim 7 , wherein the pair of the ends of the spring-like one-piece, arch shaped connectors include a generally flat mounting portion.
