Abstract
In carrying out a loft conversion some way has to be found of reinforcing the triangular timber roof trusses so that the internal bracing can be removed, to make the space. In the invention this is done by fixing C-sections to the outline of the triangular trusses, preferably sandwiching the timber frame. For the C-sections to overlap at the corners, part of one flange, e.g., the upper flange of the horizontal beam, is removed, and then the beams are bolted onto the frame. The process can be carried out with minimal disruption to the roof as no transverse (longitudinal) reinforcement is needed. A dormer process can also be included, making use of a versatile reinforcement plate.
Claims19
A timber framework for a roof having at least one corner where two timber beams meet, each of the timber beams reinforced by a C-section metal beam having a central web and a pair of flanges forming the C-section, affixed to one or both respective sides of the timber framework, each C-section beam with its central web in contact with only one side of one of the timber beams and its pair of flanges facing outward in a common direction from the timber framework, in which at the at least one corner of the framework the C-sections overlap and at least one outwardly projecting C-section flange is locally removed to allow contact between the central web.
A roof structure comprising reinforced timber frameworks, at least one of the reinforced timber frameworks having at least one corner where two timber beams intersect, each of the timber beams reinforced by a C-section metal beam affixed to one or both sides of the timber framework, each C-section beam with a central web in contact with only one side of one of the timber beams and a pair of flanges facing outward in a common direction from the timber framework, in which at the at least one corner of the framework the C-sections overlap and at least one outwardly projecting C-section flange is locally removed to allow contact between the central webs.
A roof framework including an inner apex corner where two timber beams meet at an obtuse angle, the inner apex corner reinforced by a metal plate having a central part overlaying a side surface of the inner apex corner and having two arms that extend at the obtuse angle along the beams, means to attach the plate to the inner apex corner, and an upstanding flange that orthogonally extends from an inward (obtuse-angled) side of the central part, serving to reinforce the plate and extend into the obtuse-angled space between the beams on an interior side of the roof framework so as to afford a surface for later application of finishing when the roof framework is complete.
