Analysis and Strengthening of Carpentry Joints 1. Introduction 2

Branco Assistant Professor ISISE, Dept. Civil Eng., University of Minho Guimarães, Portugal Thierry Descamps Assistant Professor URBAINE, Dept. Structural Mech. and Civil Eng., University of Mons Mons, Belgium 1. Introduction Joints play a major role in the structural behaviour of old timber frames [1]. Current standards mainly focus on modern dowel-type joints and usually provide little guidance (with the exception of German and Swiss NAs) to designers regarding traditional joints. With few exceptions, see e.g. [2], [3], [4], most of the research undertaken today is mainly focused on the reinforcement of dowel-type connections. When considering old carpentry joints, it is neither realistic nor useful to try to describe the behaviour of each and every type of joint. The discussion here is not an extra attempt to classify or compare joint configurations [5], [6], [7]. Despite the existence of some classification rules which define different types of carpentry joints, their applicability becomes difficult. This is due to the differences in the way joints are fashioned depending, on the geographical location and their age. In view of this, it is mandatory to check the relevance of the calculations as a first step. This first step, to, is mandatory. A limited number of carpentry joints, along with some calculation rules and possible strengthening techniques are presented here. -

The exercises in wood-working in this book were pre- pared by me during the summer of 1883, for the students of the College of the City of New York. Subsequent teaching suggested many changes and additions, until the manuscript was scarcely presentable. This manuscript has been copied for other schools ; and now, in order that those who have recently asked for it may receive it in better shape, this little volume is printed. I am indebted to Mr. Bashford Dean for the part relat- ing to injurious insects, which was written expressly for this book. I. S. New York, September, 1889.

The traditional techniques used in ancient churches and temples, with their of Timber high-vaulted ceilings, sweeping curves and enduring strength, still influence today’s structures. The hallmarks of heavy timber—prominent wood beams and timbers—now also include elegant, leaner framing that celebrates the with Modern expression of structure with a natural material. A visual emphasis on beams, purlins and connections lends character and a powerful aesthetic sense Construction of strength. Historically a handcrafted skill of mortise and tenon joinery, heavy timber construction has been modernized by tools such as CNC machines, high- strength engineered wood products, and mass-production techniques. A growing environmental awareness that recognizes wood as the only renewable and sustainable structural building material is also invigorating this type of construction. Heavy timbers are differentiated from dimensional lumber by having minimum dimensions required by the building code. Modern versions include sawn stress-grade lumber, timber tongue and groove decking, glued-laminated timber (glulam), parallel strand lumber (PSL), laminated veneer lumber (LVL) and cross laminated timber (CLT). Structural laminated products can be used as solid walls, floors and columns to construct an entire building. Modern heavy timber construction contributes to the appeal, comfort, structural durability and longevity of schools, churches, large-span recreation centers, mid-rise/multi-family housing and supermarkets, among many other buildings. -
Itening Guide
itening Guide There are three essential tasks involved in the making of any woodwork project. The first is to cut out and shape the components; the second is the joining of those components; and the third and final task is the finishing of the article. This appendix provides you with information about the best ways to fasten your workpieces together, to ensure your project's long life. The options are between adhesives, nails, screws and bolts. NAILS Nailing is a quick, efficient and economical way of joining timber. lf the correct nails are chosen, there is no reason why the joints should not be durable. Timber framed houses, with most of the framing just nailed together, have stood the test of time. The listing of nail types that follows provides an overview of commonly used nails. This listing is not complete - nails exist for specific purposes such as boat-building, but these are outside the requirements of the normal handyman. _ Nail Types: Gommon Bullet Head: Used for hardwood framing and general fixing. Flat Head: Used for softwood framing, fixing softwoods or anywhere bullet heads would tend to pull through. Wire Brads: Small bullet head nails, used for attaching decorative mouldings. Clouts: Small nails with a relatively large flat head, used for attaching thin sheet material. Nail Types: Special Purpose Tacks: Used principally for upholstery; commonly blue- black in colour. Panel Pins: Used for fixing plywood panelling to timber framing; "brown" plated. Hardboard Nails: Used to attach hardboard ("masonite"); generally zinc plated. Plaster Board Used for fixing plasterboard to timber framing; Nails: zinc plated. -
Chippendale Mirror
uring the late 18th century, elaborately framed mirrors, known as looking glasses, served as testimonials to the Dwealth of their owners. A looking glass similar to the one shown here would have cost the owner 10 to 12 shillings, a hefty price considering that the average wage for a skilled tradesman of the time was about 6 shillings a day. This is the first serious piece I give my students to make. Be- cause I’m blending a traditional piece into a modern curricu- lum, I don’t go nuts over historical precedence and technique, and I take full advantage of modern machinery. For a small project, this mirror introduces a wide range of skills from basic design and layout to veneering and scrollwork. Each year, my class ends up with a great collection of stunning mir- rors that they present as thank-you gifts to mom and dad for the thousands doled out for tuition. Begin by constructing a two-layer frame Despite its elaborate appearance, this project has only two main parts. The frame, which I make first, consists of a visible mitered molding in mahogany that sits on top of a poplar subframe; sur- rounding it are scrollsawn parts made from a shopmade core with figured veneer (in this case makore) as the face veneer and plain veneer on the back. The common way to build a frame is to use 3⁄4-in.-thick primary Build a wood and miter the corners. Even when the joints are splined or Chippendale Mirror nailed, this is a poor approach. -
