It can contain any number of defects.During the s, the timber used for framing was generally visually graded No. Early in the decade, wall framing was typically wet or green and allowed to dry after the walls were erected. With the introduction of LOSP treatment the use of dried timber framing, particularly for pre-nailed wall frames, increased. Wet timber lintels and beams and long span floor and ceiling joistsunless propped until dry, were often subject to sagging as roof loads were applied.

Frames were typically constructed on site with the builder doing the timber grading as he sorted through the delivered packets of timberalthough pre-nailed frames became available as the decade progressed. The introduction of NZS in gave specific requirements for wall framing sizes and spacing. Wall framing typically consisted of gauged x 50 mm timber studs fixed to x 50 mm top and bottom plates. The standard stud height was 2. Studs were generally spaced at mm centres with dwangsor nogs horizontal timber blocking between studs installed in horizontal rows at mm maximum centres, or as required, to provide edge fixing for sheet lining materials, or to support internal joinery.

Early in the period, bracing Figure 1 was solid angle bracing consisting of lengths of 75 x 50 mm or x 50 mm timber cut and fitted on an angle between the studs and the dwangs Figure 2.

As the decade progressed, the timber bracing was replaced with a cut-in 25 x 25 mm galvanised metal angle punched for nailing Figure 3as it was much easier and quicker to install. Back to top. The bracing strength of existing construction is often not known.

What should be used in the bracing calculations required by building consent authorities when repairs or renovations are planned? BRANZ tested a range of older bracing systems to provide wall bracing ratings. Where a particleboard floor was installed, all wall framing was erected on the particleboard floor. If a timber strip floor was to be installed, external and internal loadbearing wall frames were erected before the flooring was laid, so bottom plates were fixed directly over the floor joists.

Kraft black bitumen impregnated building paper was installed on the exterior face of the wall framing. Synthetic building wraps became available during the early s. Insulation within exterior walls was not a mandatory requirement untilso it was not generally installed see Insulation. Framing for two-storey construction was typically platform framing, where lower walls were erected, floor joists installed, and the particleboard laid to provide the platform on which the upper floor walls were constructed and erected.

Platform construction effectively utilises two walls of framing one for each level separated by the floor joists of the first floor. Studs are therefore not continuous through both levels and bracing is also separately run between the bottom and top plate of each storey. Wall framing was typically x 50 mm pinus radiata.

New Zealand pine is a light coloured, medium density softwood with a moderately even texture that produces sawn lumber with excellent working properties.

Sawn New Zealand timber dries easily and can be kiln dried rapidly from green. The wood can be readily treated with preservative to achieve all desired durability levels. Through good silviculture management, New Zealand pine logs come in a range of qualities capable of yielding lumber grades to meet almost any requirement.

For finishing and furniture uses, can either be clear of knots or contain minor blemishes and tight knots. These grades include:. Used primarily for construction where strength and stiffness are important.

The main factors influencing a structural grade are the size and location of knots. Grade limit such defects to meet specified strength requirements. Used in packaging for various products such as pallets, cable drums and concrete formwork. Grades contain a range of knot sizes compatible with final use. Industrial grades are also produced for export including thin board and a range of other grades to buyer specifications. New Zealand timber producers are able to grade to most customer requirements.

Common export grades include:. These are rough sawn not planed dried sizes. Preservative Treatments Effective preservation treatments have been developed to ensure New Zealand pine has excellent performance across a broad range of applications.

New Zealand has developed a world leading wood preservation industry and has rigorous codes of practice and the industry has been audited to these for over by Woodmark hyperlink to the woodmark site. Woodmark is the leading quality assurance programme for preservative treated timber. In New Zealand, round wood posts and polessawn timber and plywood are treated to six different hazard class levels. Preservative treatment requirements are generally equivalent to or exceed those of other countries that have formal wood preservation standards.

This Guide sets out the hazard classes for treated timber that are appropriate for given end uses. New Zealand Radiata Pine New Zealand pine is a light coloured, medium density softwood with a moderately even texture that produces sawn lumber with excellent working properties.

These grades include: Clear Timber: Free of knots and blemishes, used for high-quality joinery, furniture and mouldings. Cuttings Grades: For reprocessing to produce shorter clear lengths with excellent machining and gluing properties.Read more. Following the Acceptable Solution is one way to comply with B1, but you can choose other ways to comply. NZS is used to design most homes and other low-rise timber-framed buildings in New Zealand.

A first in New Zealand for all timber construction

NZS has been around in one form or another since the aftermath of the Napier earthquake in It provides prescribed methods for the design and construction for timber-framed, low-rise buildings to meet the requirements of the Building Code without the need for specific engineering design.

Building Code clause B1 Structure requires buildings to withstand loads they are likely to experience during construction, throughout their life and when they are altered. These loads include those from people, wind, earthquakes and snow.

The design, construction and alteration of structural work in residential properties is likely to be restricted building work that must be undertaken by a licensed building practitioner. It sets out construction requirements for timber-framed buildings on good ground, and up to a maximum of three storeys in height with attic spaces.

By limiting the size of the building and scope of application, NZS presents a series of solutions, enabling a designer to select an element or detail without having to engage a structural engineer. In referencing NZSthe Acceptable Solution for B1 Structure contains some modifications about reinforcing concrete slabs on ground and foundations. This applies to all regions in New Zealand. The modification to the definition of good ground made for the Canterbury Earthquake Region to exclude ground subject to liquefaction or lateral spread still applies, but only to that region.

Read more about building on ground subject to liquefaction. The first section contains notes on the scope and interpretation, general requirements and site requirements. Definitions of spans and loaded dimensions are also given. Any design details not included in NZS will require specific design. Similarly, any variations to a given design detail in NZS such as different fixings will require specific design. If you are familiar with common methods and details for designing and constructing timber-framed buildings, this handbook will provide a useful reference.

It contains a collection of figures and tables extracted from NZS Timber-framed buildings, with some associated text. This information is commonly used in the design and construction of timber-framed buildings up to three storeys in height including residential buildings, garages and decks.

Our timber is also treated with chemicals to improve its resistance to pests and rot. Timber frames are partly popular simply because they are so common — builders and architects are familiar with them and so they use them. For this reason, timber house framing is often the easiest option. Planks of timber known as studs are attached at a perpendicular angle to other pieces of timber that lie across their tops and bottoms wall plates.

A strong but flexible material such as plywood or oriented strand board is then attached to the studs on their external side.

This sheath helps to give the frame structural stability. Struts fitted diagonally between studs will also enhance the strength of the building. This arrangement of studs, plates, sheath and struts is constructed lying flat on the ground. From this point, the pre-nailed roof trusses and roof rafters are attached.
