GUIDANCE ON USE OF FRAMING ANCHORS FOR SPECIFIC TIE-DOWN TO MULTIPLE TOP LATES (RIBBON PLATE CONSTRUCTION)

Framing Anchors

There has been extensive discussion of late in the housing sector (TQ, HIA, Truss Plate Manufacturers, Certifiers, Designers and Builders etc) regarding the requirements of AS 1684 Part 2 Non-cyclonic and Part 3 Cyclonic and the use of framing anchors – triple grips and multi grips, to provide specific tie-down to multiple top plates (ribbon plates). TQ published an article in a recent ‘Timber Talk’ Technical Update Newsletter outlining our views. In brief, the article said that if the framing anchors were only nailed to the ribbon (upper) plate, then the specific tie-down requirement would be deficient as there would be a discontinuity in tie-down between the upper (ribbon) and lower plate. ThIs article sets out TQ’s opinion in respect of achieving compliance with the intent of AS 1684, which in many instances, such as this one, does not provide explicit advice.

CHECKLIST: INSPECTING TIMBER DECKS, VERANDAHS & BALCONY IN HOUSES & UNITS

TIMBER-MAINTENANCE-CHECKLIST

Regular inspections are essential to ensure structural safety. Managing risk by checking for strength, decay, termites and corrosion is vital. This easy to follow checklist will ensure you don't miss a thing.

TECHNICAL DATA SHEET: TERMITE MANAGEMENT OF NEW BUILDINGS

All buildings, building materials and building contents are subjected to a number of hazards throughout their useful life. These include corrosion of metal, spalling of concrete, fire and water damage. Another potential hazard is termite attack of some timbers and cellulose-based materials.

There are two main types of termites capable of attacking buildings: drywood termites, which do not have ground contact, and subterranean termites, which require contact with the ground or some other moisture source. Subterranean termites are distributed throughout Queensland and are responsible for most of the termite damage of economic significance.

This data sheet provides information on how to reduce the level of risk of subterranean termite attack. In addition, potential for damage by drywood termites, including the West Indian termite, can be greatly reduced by using termite treated framing such as H2/H2F treated pine framing


 

TECHNICAL DATA SHEET: CORROSION RESISTANCE OF METAL CONNECTORS

Metal connectors are used extensively in timber framed construction both internally within the building envelope as well as externally where they are exposed to the ‘elements’. These metal connectors include items such as strapping/bracing, framing anchors, cyclone ties, joist hangers and truss plates. Just as it is with timber, it is equally important to ensure the durability of metal connectors is appropriate to the environment in which they are used. The majority of metal connectors used in construction would be expected to perform satisfactorily for the life of the building, which for normal buildings, is 50 years.

This Data Sheet provides recommendations to assist in achieving this expectation for metal connectors.


 TECHNICAL DATA SHEET: TIMBER PANELLING

This data sheet covers seasoned timber panelling for use on walls and ceilings. For continued satisfactory performance of this product, it should be fixed and finished in accordance with the recommendations included herein.

TECHNICAL DATA SHEET - FINISHES FOR EXTERIOR TIMBER

All timber (irrespective of species, durability classification, or whether it is preservative treated or not) will undergo changes when exposed to the sun and rain. Ultraviolet light and changes in moisture will cause timber to “weather”. It will lose its natural colour and fade to a silver/grey, its surface will become rough, and splits and cracks could develop. Weathering primarily affects the appearance of timber, however in the long term could affect durability and performance. Varying degrees of protection from weathering may be provided by the application of coatings such as paints, water repellents, water repellent preservatives and pigmented penetrating stains. This data sheet describes the various finishing products available and the degree of protection they provide.
