PREF CE

This manual is the end product of the FRIM/ITTO project on Research onUtilization of Tropical Timber in Construction . The project which was cqrriedout in FRIM was funded by ITTO together with some financial support fromPRIM. The aim of the project was to come up with a manual to illustrate theconstruction of a prefabricated 10w-cost' timber house.This manual is able to assist those who wish to build prefabricated timberhouses either mass-prod uced in a factory or as single uni ts. The type of housegiven in this manual is of the timber-framed type, based on the platformmethod This manual attempts to show builders the good practiceof producinghouses so that these houses can perform in a manner as expected of a goodtimber house. The fundamental principles of timber-framed housing are alsoexplained. These general principles are also applicable to other timber framemethods.

The house as described in this manual is only a typical factory made timberframed house. Other arrangements of the house as regards to layout, height,size, etc. are possible and can be built using similar procedure and guidelinesas given in this manual.

INTRODU TION

There are at present in Malaysia a number of factories making prefabricatedtimber houses using their own proprietary system of construction. The prefabricated house as proposed here is another method of construction where theparts of the house may be assembled in the factory or at the site in a do-ityourself manner. Since there are very few guides available on the constructionof timber houses it is believed that a manual of this type illustrating suchconstruction would be useful to builders of timber houses.

The aim of this manual is to recommend a system of construction not as aclose proprietary system but as a general method for all who are interested inthe use of timber.

The system of prefabrication proposed in this manual is the result ofresearch carried out in FRIM on the structural strength of timber timber jointswall panels roof trusses and the different components that made up the whole

Chapter 2FABRICATION SYSTEM

There are a number of prefabrication systems in building a timber house. Thefollowing are some of them.Pre cut system

The pre-cut system is the oldest system of prefabrication. Pieces of timberare processed,cut to the required lengths, notched or drilled at the factory. Thepieces are then marked and transported to the site for assembly. Transportationof the pre-cut timber is simple because they can be bundled into units anddelivered to the building site. Compared to the conventionalmethod of cuttingtimber in falling lengths at the site, this system is more accurate in its measure-ment and material wastage is minimised. .

The traditional method of house construction in Malaysia is of the post andbeam structural form in which beams spaced widely apart between 2 and 4 min domestic buildings) are supported on individual columns or posts to form askeletal structure. The non-load bearing infill panels will form the wall andwindow units between the columns.The house proposed in this manual is the timber-framed or wood-framedhouse and falls within the category of modular panel system as mentionedpreviously. The method of timber-framed house construction is traditional inNorth America, Scandinaviaand some other parts of the world but is comparatively new in this country.Basically there are two methods of building a timber-framed house, theballoon frame and the platform frame method. The balloon frame method hasstuds running the full height of the building and the intermediate floor joists are

Chapter 4B SIC PRINCIPLES

The dimensioning of the house is based on a modular system which means thebest use is made of materials, especially sheet materials and also the house caneasily be extended at a later stage. Most sheet materials obtainable locally areof size 1220 x 2240 mm, therefore the planning of the house is based on the useof dimensions which are multiples of 610 mm. Hence a grid of 610 mm is usedin the plan layout as well as positioning in fixing of the partitions, roofs, joists,etc. These and an alternative future extension are shown in Figure 7 In themodular panel system, architects can design a wide variety of houses withmany different floor plans using prefabricated panels.

Unlike the post and beam type of constructionwhere the load is supportedby the post and beam, the timber-framed house has the wall panels supportingthe load which means the wall panels are made load bearing.n the arrangement of different components of the house, it is desirable thatroof trusses, studs in wall panels and floor joists are kept in line see Figure 8)for efficient transferring of load from the roof to the ground via these members.n this proposed house, the spacing of the trussed rafter roofs is at 1220 mmcentres while those of studs and floor joists are at 610 mm centres.

Wall panels can be of load bearing or non-load bearing walls type. Loadbearing walls re designed to support the floor nd the roof above them. Nonload bearing walls do not support ny load above them nd they function aspartitions. They are therefore m de shorter than the load bearing walls in thesame storey so that the roof or the floor joist above them does not rest on thesewalls as shown in Figure 9.

In the sequence of construction the ground is first prepared by layingconcrete footings. Posts are erected over the footing. Bearers are attachedacross the posts with bolts. Floor joistswith stiffening across pieces are laid overthe bearers. Floor boards with tongueand groove are conceal-nailed to the joistsand the platform is now ready for the next stage of construction.Over the platform pre-assembled wall panels are put up. uring this timework can also start simultaneously in the kitchen which is on ground level andwhich is not connected to the platform at this stage. When the panels are erectedover the platform as well as over the kitchen head binders or wall plates willthen bind the top of the panels together; and they also act as support for rooftrusses. The panels are also fixed firmly together sideways with nailed ironplates or angles which are then concealed with beading.

On top of the wall plates prefabricated trussed rafter roofs are fixed. Therafters are braced diagonally and purlins are nailed over them. When roofingsheets have been laid the dwelling is protected from rain and shine. Doors andwindows can now be installed. All other subsidiary works such as plumbingelectrical wiring and sanitation can be commenced.The house may now be painted and is ready for occupation.

ChapterDETAILS OF CONSTRUCTION

Site accessBefore construction begins, access to the site must be looked into, especially ifthe house is to be built in a remote area. f necessary an access road suitable forvehicles has to be constructed to transport construction materials to the site.Al though most of the component parts of the building are pre-assembled atthe factory, electric power and water supply are still required for many tasksduring the building process. Electric supply may be obtained from the supplymains or obtained from a generator. Water may be obtained from the watermains, well, river or transported to the site.At the plot, besides the area required for the proposed house, space for thestorage of prefabricated components and other building materials must beallocated away from building sites.

Check the diagonals again to make sure all corners are square.Intermediate points of the footings are next marked using a steel tape andplumb bob. The measurements should always start from the corners and movealong the string. The ini tial settings of the stakes may be corrected now i theyare not accurate. The positions of all 2 footings are now set.

measuring 150 mm wide x 50 mm thick are additionally provided below theconcrete floor where the wall panels are situated.n top of the floor, concrete curbs are used as base for the walls instead oftimber sole plates as used in the platform area, reason being the wet nature ofthe kitchen. The curbs are 50 mm thick and 115 mm wide for the thicker wallsand 50 mm x 84 mm for the thinner walls and their positions are as shown inFigure 25. Bolts 12 mm x 100 are vertically embedded in the concrete curbs forthe purpose of holding the wall panels in position. 38 mm section of the bolt

head side is inserted in the concrete and the remaining length with threads isexposed. The spacing of the bolts is about two bolts per panel (see Figure 26).The wall panels in the kitchen are sheathed both sides with cement-bondedparticleboard, 10 mm thick on the outside and 8 mm on the inside. In preassembling, only one side of the panel is first covered 10 mm side). Elongatedholes are drilled in the bottom rail of the panel which should match the boltsembedded in the concrete curb. The panel is then put over the concrete curbthrough the bolts and tightened with a nut and washer. The other side of thepanel is then covered with 8mm cement-bonded particleboard in situ. For easeof fixing the 8 mm cement-bonded particleboard to the stud, t is suggestedthat holes for nails are first predrilled on the cemboard before nailing.Wall plates are placed on top of the wall panels. Sideand corner attachmentsbetween panels are done by nailing Pryda plates or equivalent types in amanner similar to the attachments done for the plywood panels as described

bracing although temporary must be firm because all other trusses are to befastened to this end truss. The second truss can now be erected. The truss isinitiallyputupsidedownwith the two ends resting on opposite sides fthewaIlplates and the peak of the truss pointing downwards as can be seen in Figure27 above. The truss is then tilted up vertically using a long pole with a Y endas shown in Figure 28. When t is in the correct position nail bottom of truss towall plate and brace temporarily to first truss. The rest of the trusses can beerected in a similar way. Figure 29 shows the attachment of trusses to wallplates by skew nailing 4/100mm nails for each attachment two on each side ofthe truss.

oors andwin owsOpeningsfor doors windows and fixed louvers are provided for when makingwall panels. However for the door openings a full length bottom rail of thepanel is initially retained so as to prevent the frames from being twisted duringhandling. When the panels are installed this exposed portion of the bottom railis cut out together with the base plate at this place as shown in Figure 32. Doorsand windows are assembled in the factory and delivered to the site forinstallation.The doors are of three sizes: 700 mm wide for WC and bath 770 mm widefor the kitchen door and 840 mm wide for the main entrance door. The heightfor all doors is 2100 mm high measured from floor level. t is important that thedimensions of the doors and windows match exactly the openings providedfor on the wall panels after they have been installed in place. All doors shouldopen inwards.To make the doors the framework is first assembled making sure the overalldimensions are correct and the corners are squared. Plywood sheets are thenglued and nailed to the framework on both sides.Frames for windows and louvres are made at site in the openings providedfor in the wall panels. Adjustable louvre aluminium frames with 8 leaves arethen fixed to the wooden window in of

ervices

Various services such as plumbing, electrical and sewerage works, can beinstalled in the building as soon as the roof is covered with roofing sheets. Forgeneral wiring, drilled holes in wall frames and floor joists are used. The holesmeasuring 25 mm diameter are drilled at the centre of the section. They shouldbe located at least 300 mm away from the ends of studs, joists and otherstructural pieces, and from any other hole as shown in Figure 35.

Notches for piping and wiring can be made at the joists if the followingconditions are followed:1) All notches must be in top edge of joist,2) The location of the notches from the support end should be between

1 10 and 1 5 of the joist span, and3) Maximum depth of notch is equal to 21 mm for a 145 mm joist.Instead of notches, holescan be drilled in joists for piping as shown in Figure36. All fixtures and fittings can be fixed to the framing timbers forming thepanels. Extra noggings can be added to support heavy fixtures such as washbasins or boilers.

ChapterM INTEN NCE ND REP IR

A house if properly designed and constructed with adequate attention givento details and to proper choice of materials used as outlined in this handbook,would require little maintenance. The following are some of the suggestionsthat may be followed to reduce the cost of maintenance. However, it mustalways be borne in mind that the two points to ponder are deterioration oftimber house caused by termite attack which is mostly found in the tropics anddecay caused by moisture and dampness.Raised platform1) Space beneath the platform should be well ventilated. Open spaces mustnot be blocked by obstacles, including grasses, shrubs and planting.2) o water should be allowed to collect under the building. Hence the

4) If the paintingor finishes of the wall surfaces show signs of deterioration,apply fresh coats of paint.nterior1) If there are cracks in the interior walls, fill the cracks with putty nd p intover as in exterior walls.2) Do not allow moisture to remain long on the surface of ny timber orplywood especially in the kitchen area.3) The sheathings of wall panels may be accidentallyd m ged resulting inholes or cracks in the sheets. If the holes are small they m y be filled upwith putty nd sanded smooth. Larger holes may require cutting asection around the damaged portion nd replacing it with a new section.4) Gaps may form between the floor boards due to shrinkage of the boardsbecause they were originally laid with very high moisture content. One

remedial action is to fit matching strips of timber between the flooringstrips nd glue them in place. In severe cases it may be necessary toreplace sections of the floor.Roof
