Abstract
Segmental duct coupler devices, systems, and methods are provided herein. A duct coupler device can include a single, discrete body of material for welding to a duct segment. A system, including a duct segment having a duct coupler device welded thereto, is provided. The connection or points of connection between the duct coupler device and the duct segment in the system are devoid of internal and/or external seals. The duct coupler device and system can be cast in concrete. Multiple concrete segments can be assembled together to form a bridge, a roadway, a building, a slab, or any other structure.
Claims26
A duct coupler device for use in assembling concrete segments, the system comprising:
- a single, discrete body of material, wherein the body of material is annular and comprises:
- a variable internal diameter;
- and
- a variable outer diameter;
- wherein the body of material comprises a weldable material that is configured to weld to a duct segment.
A method of providing a duct coupler system, the method comprising:
- providing a duct coupler device comprising a single, discrete body of material;
- providing a duct segment;
- and
- welding the duct coupler device to a first end of the duct segment, wherein the connection between the duct coupler device and the duct segment is devoid of internal and/or external seals.
A duct coupler system, the system comprising:
- a first duct segment comprising a first end and a second end that opposes the first end;
- and
- a second duct segment comprising a first end and a second end that opposes the first end;
- wherein the first end of each of the first and second duct segments comprises a first duct coupler device welded thereto;
- wherein the second end of each of the first and second duct segments comprises a second duct coupler attached thereto;
- and
- wherein the first end of the first duct segment is configured to couple to the second end of the second duct segment.
