Abstract
A structure including a first hollow-section Fibre Reinforced Polymer (FRP) member, and a second hollow-section FRP member arranged at an angle to the first member. A rod extends through the second member. The rod also has a threaded end section extending through or into the first member. The opposed end of the rod is fixed to a further member. A nut secures the threaded end section to the first member, and screwing of the nut and threaded end section together exerts a compressive force on the second member and a tensile force on the rod.
Claims12
A truss comprising:
- a pair of first hollow-section members;
- a plurality of second hollow-section members extending between the pair of first hollow-section members, each arranged at a respective angle to at least one of the first hollow-section members;
- a plurality of third members extending diagonally between the pair of first hollow-section members;
- a plurality of rods, each rod extending through a respective second hollow-section member and a respective third member, and having opposing first and second threaded end sections extending through or into the first hollow-section members;
- and
- a plurality of pairs of nuts for securing said threaded end sections to the first hollow-section members, wherein said pairs of nuts are located inside the pair of first hollow-section members, and wherein screwing each pair of nuts and the opposing threaded end sections of each rod together exerts a compressive force on each second hollow-section member and a tensile force on each rod.
3 more elements
A kit of parts for constructing a truss comprising:
- at least two hollow-section Fiber Reinforced Polymer (FRP) chords;
- a first plurality of hollow section FRP webs;
- a plurality of rods having threaded end sections and configured to be located coaxially within respective first plurality of hollow section FRP webs;
- a second plurality of hollow section FRP webs configured to be coupled between adjacent hollow section FRP webs of said first plurality of hollow section FRP webs and the opposed chords such that they extend at a diagonal between the chords, each of the second plurality of hollow section FRP webs having a pair of holes at each end aligned to allow a threaded end section to pass therethrough;
- a plurality of pairs of end nuts for engaging with the threaded end sections of the rods to secure both the first and second plurality of hollow section FRP webs between the chords, the pairs of end nuts configured to be located inside the hollow-section FRP chords in use;
- and
- wherein screwing of the nuts and the threaded end sections together exerts a compressive force on the chords and both the first and second plurality of hollow section FRP webs and a tensile force on the rods.

A method of assembling a kit of parts for constructing a truss, the kit of parts having:
- at least two hollow-section Fiber Reinforced Polymer (FRP) chords;
- a first plurality of hollow section FRP webs;
- a plurality of rods having threaded end sections and configured to be located coaxially within the respective first plurality of hollow section FRP webs;
- a second plurality of hollow section FRP webs configured to be coupled between adjacent hollow section FRP webs of said first plurality of hollow section FRP webs and the opposed chords such that they extend at a diagonal between the chords, each of the second plurality of hollow section FRP webs having a pair of holes at each end aligned to allow a threaded end section to pass therethrough;
- and
- a plurality of end nuts for engaging with the threaded end sections of the rods to secure both the first and second plurality of hollow section FRP webs between the chords and wherein the pairs of end nuts configured to be located inside the hollow-section FRP chords in use, wherein the method comprises:
- engaging said end nuts with respective threaded end sections of the rods, about or within the chords, and screwing the nuts and the threaded end sections together to exert a compressive force on the chords and both the first and second plurality of hollow section FRP webs and a tensile force on the rods.
