Abstract
A method of making a virgin joint between at least two separate structural hollow sections in a truss or jacket structure made of the at least two structural hollow sections may include the steps of applying a fiber reinforced polymer wrap around the at least two structural hollow sections in a transitional area, covering and thus bonding together the at least two structural hollow sections, and forming the virgin joint between the at least two structural hollow sections and the fiber reinforced polymer wrap. Welding of the virgin joint between the at least two structural hollow sections is avoided.
Claims25
A virgin joint between two separate structural hollow sections for assembling a prefabricated lattice tower structure, or for assembling a prefabricated truss structure, made of such structural hollow sections, the virgin joint is fatigue resistant and comprising a fiber reinforced polymer wrap around the structural hollow sections in a transitional area forming a tapered joint, covering and thus bonding together those portions of the two structural hollow sections that, together with the fiber reinforced polymer wrap, form the virgin joint between the two structural hollow sections, wherein the thickness of the wrap is gradually reduced from a maximum thickness at a root of the joint towards the end of the wrap as seen in the longitudinal direction of the hollow section to form a smooth geometry,
- wherein the virgin joint excludes welding, and wherein the joint is an at least uniplanar joint of a K, X, T, N, Y shape, or a combination of these shapes.
A method for making a virgin joint between at least two separate structural hollow sections in a prefabricated lattice tower structure, or prefabricated truss structure, made of the at least two structural hollow sections, the method comprising the steps of:
- applying a fiber reinforced polymer wrap around the at least two structural hollow sections in a transitional area forming a tapered joint, covering and thus bonding together the at least two structural hollow sections, wherein the thickness of the wrap is gradually reduced from a maximum thickness at a root of the joint towards the end of the wrap as seen in the longitudinal direction of the hollow section to form a smooth geometry;
- forming the virgin joint between the at least two structural hollow sections and the fiber reinforced polymer wrap, wherein the fiber reinforced polymer wrap acts as a transition piece for transferring forces between the structural hollow sections, such that welding of the virgin joint between the at least two structural hollow sections is not required;
- and
- wherein the joint is an at least uniplanar joint of a K, X, T N, KT, Y shape, or a combination of these shapes.
