Book Description
To obtain the best attainable end-use stability of a wooden product it is essential to have information on the movement and shrinkage that may be expected. In this context, it is essential when drying timber to choose an accurate drying schedule in relation to the shrinkage figures and the risk of deformation. Generally, many timber properties are closely related to the density and the nominal specific gravity. With the given detailed information (per wood species), the water content (amount of evaporation and energy in timber drying) or the void volume (in case of impregnation, in order to estimate the maximum uptake of a liquid) in the wood can be calculated. The physical properties of 145 commercial timbers have been determined in the past decades. They comprise the shrinkage and swelling values, equilibrium moisture content, hysteresis, density and nominal specific gravity, including the variation coefficients of these values. The shrinkage, swelling and hysteresis are presented in graphic form; the other information in tabular form. Additional information about some other properties of physical nature has been added, e.g. gluelam products and rattan.

Book Description
All those of us without traditional skills need to know to build with timber framing Many natural building methods rely upon the use of post and beam frame structures that are then in-filled with straw, cob, cordwood, or more conventional wall materials. But traditional timber framing employs the use of finely crafted jointing and wooden pegs, requiring a high degree of craftsmanship and training, as well as much time and expense. However, there is another way... Timber Framing for the Rest of Us describes the timber framing methods used by most contractors, farmers, and owner-builders, methods that use modern metal fasteners, special screws, and common sense building principles to accomplish the same goal in much less time. And while there are many good books on traditional timber framing, this is the first to describe in depth these more common fastening methods. The book includes everything an owner-builder needs to know about building strong and beautiful structural frames from heavy timbers, including: the historical background of timber framing crucial design and structural considerations procuring timbers-including different woods, and recycled materials foundations, roofs, and in-filling consdierations the common fasteners. A detailed case study of a timber frame project from start to finish completes this practical and comprehensive guide, along with a useful appendix of span tables and a bibliography. Highly illustrated, this book enables 'the rest of us' to build like the professionals and will appeal to owner-builders, contractors and architects alike.

Book Description
Der Holzbau hat sich grundlegend erneuert. Er hat gegenüber Konkurrenzbaustoffen deutlich an Marktanteilen gewonnen und wird von Systemen wie Rahmen-, Skelett- und Massivholzbau dominiert. Jeder Holzbau ist durch Struktur bestimmt. Dabei ist es wesentlich, die Zusammenhänge vom Entwurf bis zur Konstruktion zu kennen. "Holzbau mit System" geht dieses Thema auf völlig neue Weise an. Es ist eine analytische, visuell aufgebaute Gesamtdarstellung vom einfachen Einfamilienhaus bis zum mehrgeschossigen Grossbau. Einbezogen sind auch die für das Energiesparen so wichtige Gebäudehülle und die konstruktiv grundlegenden Systeme für Decken und innen liegende Trennwände. Dieses Werk zeigt mit Plänen, schematischen Zeichnungen und Bildern den aktuellen und zukunftsweisenden Stand der Technik, konkretisiert am Beispiel der Schweiz, einem führenden Land im innovativen Holzbau.

Book Description
Carpentry and Joinery 2 is the second in a series of three books, which together provide an authoritative and thoroughly practical guide to carpentry and joinery for students following City & Guilds and CITB courses, NVQ candidates, and students working towards an Institute of Carpenters qualification. This book is also ideal for a wide range of amateur and professional woodworkers. Volume 2 builds on the fundamental knowledge introduced in volume 1, by covering more advanced topics and procedures, including machine tools. Essential ‘back-up’ topics are presented throughout the text to revise the key aspects covered in volume 1. The reader is shown how to apply this basic theory to actual carpentry and joinery practice in a highly illustrated, easily accessible text. The third edition has been fully updated in line with changes to the Building Regulations and current legislation, the third edition also incorporates developments in current best practice, with a comprehensive match to the latest qualifications in Wood Occupations.
