Abstract
A method for strengthening a truss having a principal rafter and a plurality of struts coupled to the principal rafter, defining a frame structure of the truss. The method includes the use of a bracket which is coupled between the principal rafter and one of the struts. The bracket includes a channel arranged to receive and mount the rafter therein. A strut anchor is coupled to the channel and extends outwardly therefrom for anchoring the channel on an outermost strut defining an end of the truss. The bracket provides torsional support and load bearing support between the strut and the principal rafter.
Claims13
In combination with a building comprising a supporting structure including two, spaced apart bearing walls, a truss for supporting a roof on the supporting structure, the truss comprising:
- an elongate frame structure;
- a principal rafter extending longitudinally with the frame structure and past respective ends thereof, and having a pair of mounting portions located at respective ends of the principal rafter supporting the rafter on the bearing walls;
- and
- a reinforcement device comprising:
- a channel receiving the principal rafter therein;
- channel mounting means mounting the channel on the principal rafter between the frame structure and one of the mounting portions;
- and
- a rigid anchor secured to the channel and extending outwardly therefrom;
- and
- anchor mounting means mounting the anchor on the frame structure.
A truss for supporting a roof on a supporting structure including two, spaced apart bearing walls, the truss comprising:
- an elongate frame structure;
- a principal rafter extending longitudinally with the frame structure and past respective ends thereof, and having a pair of mounting portions located at respective ends of the principal rafter for supporting the rafter on the bearing walls;
- a channel mounted on and secured to the principal rafter between the frame structure and one of the mounting portions;
- and
- a rigid anchor extending between and secured to the channel and the frame structure;
- and wherein:
- the frame structure includes a plurality of struts and an outermost pair of the struts define the respective ends of the frame structure;
- the anchor is mounted on one of the outermost struts;
- and
- the outermost struts each comprise an inclined support member.
A truss for supporting a roof on a supporting structure, the truss comprising:
- an elongate frame structure;
- a principal rafter extending longitudinally with the frame structure and past respective ends thereof, defining a pair of mounting portions located at respective ends of the principal rafter for supporting the rafter on the supporting structure;
- a channel mounted on one of the mounting portions of the principal rafter and securing the rafter therein, the channel comprising a clamp member of C-shaped cross section having a base and a pair of flanges extending therefrom for engaging respective sides of the principal rafter;
- and
- a rigid anchor extending between and secured to the channel and the frame structure.
A method of reinforcing an elongate truss having an elongate frame structure and an elongate principal rafter extending longitudinally with the frame structure past respective ends of the frame structure, the method comprising:
- providing a bracket having a channel arranged to receive the principal rafter therein and an anchor for anchoring the bracket on the frame structure;
- mounting the channel on the principal rafter between an end of the frame structure and an end of the rafter;
- and
- mounting the anchor on the frame structure;
- wherein the principal rafter is supported at respective ends on a supporting structure and wherein the method includes selecting a channel having a width which is substantially equal to a spacing between one end of the frame structure and the supporting structure before the channel is mounted therebetween.
