  • 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.

  • Carpentry II EN5156
    SUBCOURSE EDITION EN5156 B CARPENTRY II CARPENTRY II Subcourse EN5156 EDITION B United States Army Engineer School Fort Leonard Wood, Missouri 65473 6 Credit Hours Edition Date: November 1995 SUBCOURSE OVERVIEW Carpentry is the art or science of measuring, cutting, fitting, and assembling wood and other materials to construct buildings or other structures. Many people associate carpenters with wood and other building materials and tools. They assume carpenters build only homes and other relatively small structures. Of course, this is not true. Carpenters work not only with wood but also with metals, plastic, and other synthetic materials. The carpentry trade includes skills required to construct buildings, bridges, docks, and wharf. Work must be accomplished in a manner consistent with environmental laws and regulations There are no prerequisites for this subcourse. This subcourse reflects current doctrine when this subcourse was prepared. In your own work, always refer to the latest publications. Unless otherwise stated, the masculine gender of singular pronouns is used to refer to both men and women. TERMINAL LEARNING OBJECTIVE: The Carpentry II subcourse, (Carpentry/Masonry Specialist, Military Occupational Specialty (MOS) 51B, Skill Levels 1 and 2), will provide you with enough knowledge to construct floor systems, stairs, wall systems (including the installation of windows and door), and roof systems of wooden structures. This subcourse is presented in three lessons. At the end of these lessons, you will be able to take a set of construction drawings and construct a wood-frame building ACTION: You will describe the construction of floor, wall, stair, and roof systems and the installation of doors and windows.

  • Wood Connections That Typically Use Nails, Bolts, and Some Specialty Hardware
    CHAPTER 7 Connections 7.1 General The objectives of connection design are • to transfer loads resisted by structural members and systems to other parts of the structure to form a “continuous load path”; • to secure nonstructural components and equipment to the building; and • to fasten members in place during construction to resist temporary loads during installation (i.e., finishes, sheathing, etc.). Adequate connection of the framing members and structural systems covered in Chapters 4, 5, and 6 is a critical design and construction consideration. Regardless of the type of structure or type of material, structures are only as strong as their connections, and structural systems can behave as a unit only with proper interconnection of the components and assemblies; therefore, this chapter is dedicated to connections. A connection transfers loads from one framing member to another (i.e., a stud to a top or bottom plate) or from one assembly to another (i.e., a roof to a wall, a wall to a floor, and a floor to a foundation). Connections generally consist of two or more framing members and a mechanical connection device such as a fastener or specialty connection hardware. Adhesives are also used to supplement mechanical attachment of wall finishes or floor sheathing to wood. This chapter focuses on conventional wood connections that typically use nails, bolts, and some specialty hardware. The procedures for designing connections are based on the National Design Specification for Wood Construction (NDS) (AF&PA, 1997). The chapter also addresses relevant concrete and masonry connections in accordance with the applicable provisions of Building Code Requirements for Structural Concrete (ACI-318) and Building Code Requirements for Masonry Structures (ACI-530)(ACI, 1999a; ACI 1999b).

  • Nail Gun Injuries in Residential Carpentry: Lessons from Active Injury Surveillance H J Lipscomb, J M Dement, J Nolan, D Patterson, L Li
    20 ORIGINAL ARTICLE Inj Prev: first published as 10.1136/ip.9.1.20 on 1 March 2003. Downloaded from Nail gun injuries in residential carpentry: lessons from active injury surveillance H J Lipscomb, J M Dement, J Nolan, D Patterson, L Li ............................................................................................................................. Injury Prevention 2003;9:20–24 Objective: To describe circumstances surrounding injuries involving nail guns among carpenters, cal- culate injury rates, identify high risk groups and preventive measures. Methods and setting: Active injury surveillance was used to identify causes of injury among a large cohort of union residential and drywall carpenters. Injured carpenters were interviewed by experienced journeymen; enumeration of workers and hourworked were provided by the union. The combined data allowed definition of a cohort of carpenters, their hours worked, detailed information on the circumstances surrounding injuries, and identification of preventive measures from the perspectives of the injured worker and an experienced investigator. See end of article for Results: Nail guns were involved in 14% of injuries investigated. Ninety percent of these injuries were authors’ affiliations ....................... the result of the carpenter being struck, most commonly by a nail puncturing a hand or fingers. The injury rate among apprentices was 3.7 per 200 000 hours worked (95% confidence interval (CI) 2.7 Correspondence to: to 4.9) compared with a rate of 1.2 among journeymen (95% CI 0.80 to 1.7). While not always the Dr Hester J Lipscomb, sole contributing factor, a sequential trigger would have likely prevented 65% of the injuries from tools Division of Occupational and Environmental with contact trip triggers.
