INTRODUCTION

The details in this handbook are a compilation of erection and bracing details that are issued with the roof layout supplied by the Prefabricated Timber Truss Fabricator as part of the site documentation or incorporated in the workshop drawings. These details cover nearly all the standard aspects of erecting and bracing all categories of timber roofs.

Alternative details may be issued by the design engineer, in which case these details override those published in this book for the particular structure that they have been designed for.

All trusses and all bracing requirements must be shown on the roof plan supplied by the truss manufacturer.

Prevailing conditions must be considered where it may be necessary for the specification of corrosion proofed nails for securing of metal bracing strap, metal connectors, hangers and fixing of timber members.

The Magisterial districts or towns specified for treatment of sawn timber as published in SANS 10005:1994 (SABS 05:1994) could be used as a guideline for use of corrosion proofed nails where doubt exists.

Note: All metal bracing, hangers, clips and the like must be fixed strictly in accordance with the manufacturer’s instructions.

PAGE 12 FOREWORD

The Institute for Timber Construction South Africa's - ITC-SA's - mission is to: Raise standards in the Nail Plated Timber Roof Truss Industry t h r o u g h the development and supportive enforcement of appropriate technical, quality and ethical standards. Monitor adherence by ITC-SA members of relevant industry related standards, SANS specifications and Codes of Practice and in so doing act as a protector of consumer interests. Foster and promote all ITC-SA members interests through appropriate advertising and publicity by facilitating training and lobbying at all relevant levels and forums.

The ITC-SA Engineering Systems who are members of the ITC-SA, namely Alpine Automation South Africa (Pty) Ltd, International Truss Systems (Pty) Ltd, MiTek Industries S.A. (Pty) Ltd, and © 2009 Multinail Africa (Pty) Ltd, have all developed computer software capable of designing timber roof structures in compliance with the relevant design codes of practise. The Systems ensure competent use of their design software through training of their licensed Fabricators. The Systems also manufacture and supply the connector nail- plates and other necessary brackets and hardware upon which the software design criteria is based.

Engineer

ITC-SA gives recognition to engineers with substantial experience and proven competence in timber engineering by accepting them as Engineer members. In order to ensure full compliance with all the provisions of both the National Building Regulations & Building Standards Act [Section 14 (2A)] and National Building Regulations [Clause A19]. These engineers may appoint, train and regularly re-train Inspectors to inspect erected Timber Roof Structures on their behalf.

PAGE 31 Fabricator

Fabricators/Truss Plants are licensed by the Engineering Systems to design and manufacture pre-fabricated, mono-planar nail-plated roof structures. They are audited by the ITC-SA on an annual basis to ensure compliance with ITC-SA requirements and the National Building Regulations and to achieve a Certificate of Compliance for Truss Manufacture.

To further assist in developing the standards within the industry, ITC-SA presents a duel level estimator/designer course which upgrades the quality and competency of personnel in truss plants.

Erector

ITC-SA approves Erectors who have undergone work evaluations and training in order to achieve a Certificate of Competence for Erectors. Of particular relevance is their understanding and correct application of the bracing rules as contained in the Roof Erector's Handbooks Volumes 1 & 2, which are continuously re-evaluated and updated through ITC-SA facilitation. These bracing details have been included in SANS10243 (The Manufacture and Erection of Timber Trusses) and some are also included in SANS 10400 “The Application of the National Building Regulations”- part L.

Inspector

ITC-SA approved Engineers appoint and train Inspectors to inspect roof structures. The Engineers accept responsibility for the design and structural stability of the roofs after inspection and approval of the roofs by the Inspectors. This process is in compliance with Regulation A19 of the National Building Regulations, which then enables the home owner to obtain an occupancy certificate from the local authority.

Truss

TOLERANCE IS CRITICAL FOR BOTH A GOOD ROOF LINE AND EFFECTIVE BRACING. A GUTLINE, PLUMBLINE OR LEVEL SHOULD BE USED. 1. TRUSSES TO BE ERECTED WITH OVERALL BOW IN ITS TOTAL RAFTER LENGTH LESS THAN L/200 AND LESS THAN 50MM (L = CHORD LENGTH). THE BOW BETWEEN BATTENS OR PURLINS MUST BE LESS THAN Lp/100 (Lp = BATTEN/PURLIN SPACING). 2. TRUSSES TO BE ERECTED WITH APEX NOT MORE THAN THE LESSER OF SPAN/200 OR HEIGHT/50 FROM A VERTICAL PLANE THROUGH ITS SUPPORTS. 3. AT ANY SECTION, THE LOCAL OUT OF PLUMB SHOULD NOT EXCEED HEIGHT/50 OR 50MM. WHICHEVER IS THE LESSER. GENERALLY, IF A BOW OR TILT IS EVIDENT TO THE EYE, THE TRUSS HAS PROBABLY BEEN ERECTED OUTSIDE THE TOLERANCES.

REV.: 0 DETAIL REF.: REMEDIAL 9 PAGE 84 01-04-2003 Part Five GLOSSARY OF TERMS AND DEFINITIONS Apex: The top of the truss where the two top chords meet. Batten: Small section timber members (usually 38x38 or 38x50) nailed across the top chords at a spacing of less than 540mm to carry concrete tiles, slates, metal tiles etc. Binder: See Runner. Block Splice: Nailed timber block used to join butting bracing members and purlins. Bottom Cord: Also tie-beam. That part of the truss that forms the bottom edge, and joins the two heel joints, supports the ceiling, and usually flat . Sloped in scissor trusses. Abbreviated B.C. Braced Bay: That section of roof where the diagonal bracing members are fixed. Bracket: See Cleat. Bracing: Timber members (or of other material e.g. light gauge mild steel) fixed to several adjacent trusses usually at a 45 degree angle to make the roof stable, and to prevent buckling of compression members. Brandering: Similar to battens but fixed to the bottom chord, to support the ceiling. Cantilever: When the truss support on the bottom chord is some distance inside the heel joint. Clear Span: The distance between the supporting walls (or inside face of the supports). See also span. Cleat: Mild steel heavy-duty bracket fixed with bolts and used to support large heavy trusses / girder on a girder. Crank: When the support wall direction change is less than 90 degrees. The roof forms a bastard hip on one side, and a valley on the other in double- pitched roofs. Clout Nails: Wire nails 32mm long, 2.8mm in diameter, with a large head used to fix hangers, hurricane clips and pre-punched strapping. (i.e. light gauge metal to wood) Double Pitch: Trusses where the top chords slope up to the apex at the same angles (pitches) from both ends of the truss. Dual Pitch: Trusses where the top chords slope up to the apex at two different angles (pitch) from each end of the truss. Dutch Hip: A hip end where the end slope does not reach the apex but the top part of the hip forms a small gable. Also called a louvre hip. Fly Rafter: The top chord overhang at the high end of the mono pitch jack truss which extends over the truncated hip girder and trusses. (May also be a separate loose rafter) Gable: When the building end is vertical, the same shape as the truss, usually constructed of brickwork. Gablet: Small gable on the roof slope, usually formed by a valley set. Girder Truss: A truss (single or multiple ply) used to support other trusses. Hanger: A U-shaped bracket made of light gauge galvanized mild steel used to support trusses on a girder, usually fixed with 32mm clout nails or similar. When specified, may also be fixed with bolts and 36x36X4mm washers.

PAGE 85 Heel: The truss end joint where the top and bottom chords connect, or where the end web joins the bottom chord in stub and mono-pitch trusses. Heel Shelf: A means of fixing the diagonal top chord bracing at the wall plate using timber, bolts, washers, nailed hurricane clips and thrust block. Hip: When the building ends in a sloped roof (as compared to a gable). Hoop Iron: Galvanized metal strips built into brickwork used to hold down trusses. Hurricane Clip: A light gauge galvanized mild steel angle bracket used to fix two timber members at 90 degrees to each other. Jack Rafter: The smallest end part of a hip corner construction using only single pieces of timber (loose rafter). Jack Truss: The mono pitch trusses of the hip, which are supported at the high end by the hip girders. Member: A part, or component, which together with other members make up the structure. (i.e. truss members are the top chords, bottom chords and webs which form the truss) Mono Pitch: A truss where there is only one rafter slope. (half of a double pitch truss) Multiple Plies: Two to four trusses nailed and bolted together to form one unit. Usually as girders. Nails: See Clout nails and Wire nails. Nib: Extensions of the bottom chord past the truss end, usually to support in brickwork or on a truss hanger. Node: Also node point or joint. The places on the truss where two or more truss members are connected to each other (but not chord splices) Overhang: That part of the truss top chord that extends past the truss heel. Measured horizontally from the truss heel on the truss, but also from the outside wall face on the building. Pitch: Also slope, the angle between the top chord and the horizontal line from the support point. Can also be the slope of the bottom chord in a scissors truss. Plumb: Trusses to be in a straight vertical line, i.e. 90 degrees to the floor (horizontal) level and parallel to the gable wall. Plumb Cut: Top chord overhangs cut off vertical, i.e. up / down, to allow the fixing of fascia boards and/or square gutters at the roof truss ends. Polynesian: Trusses with a pitch change in each top chord from a lower pitch to steeper pitch going from heel to apex. Purlin: Timber sections (usually 50x76) fixed across the top chords at a spacing of up to 1200mm to carry metal and fibre cement sheeting. Rafter: See Top Chord. Runner: Bracing members that are run continuously through the entire roof or set of the same trusses, to connect the same point of each truss. Runners must be diagonally braced at every braced bay to have any effect on the stability of the roof structure.

PAGE 86 Spacing: The distance between the centres of two of the same elements, i.e. trusses. Span: Truss span is the distance along the bottom chord between the truss ends (heels). See also Clear Span. Splice: The joining of two members in a straight line so that these members act as one component, e.g. truss top and bottom chords, and runners. Truss webs may not be spliced (Unless approved by an engineer). Stub End: Also stub heel. Where the top and bottom chords are some distance apart and connected by the first truss web. Support: The point where the truss is carried by the building below. The wall (or beam) should be built to carry the truss, and there should always be a node at the support point of the truss. Tie Beam: See Bottom Chord. Top Chord: Also rafter. That part of the truss, which forms the top edge, usually at a slope and has the battens or purlins fixed to it to carry the roof covering. Abbreviated: T.C. Truncated: A hip truss or girder, which has a part flat top chord, at a height so that the fly rafters of the jack trusses can just pass over the top. Also the lower truss of the 'piggy-back' or 'top-hat' truss system, i.e. when large high trusses are split horizontally into two halves for manufacturing, handling and transport purposes. Truss: A number of timber members joined together in a triangular pattern to form a sturdy frame to carry the roof covering and any other loads that it is designed for. Labels: All trusses should be labeled on the roof layout plan and on the truss itself. Common labels are A1, TR1, GX1, TG1, HG1, HM1, etc. Under-gable: Formed by two adjacent double pitched trusses of different spans, where both heels are on the same wall on one side only. Valley: A set of special trusses with decreasing spans which are supported on the length of their bottom chord by the top chords of the trusses underneath and fixed at 90 degrees to these trusses. Valley Truss: A truss, which is supported by other trusses underneath. Wall Plate: A timber member laid flat over the supporting wall to level the bearing surface and spread the load. Webs: The truss members that connect the top and bottom chords, usually in a triangular pattern. Wedges: Triangular timber blocks used in pairs to level the trusses. Wire Nails: 75mm or 100mm long, 3 to 4mm diameter wire nails with a head, used to connect two timber members together. Wire Ties: Two strands of wire built into the brickwork used to hold down the trusses.
