4 VALUE OPEN WEB FLOOR SOLUTION Overview Build it fast... Build it for less... A popular open web floor system, SpaceJoist will give your project the competitive edge with marked savings in time and money. SpaceJoist offers today s builder an engineered floor system that combines the best features of an I-joist with an open web construction to deliver a quality product for maximum job site efficiency and overall cost effectiveness. OPEN WEB FEATURE ALLOWS FOR SERVICE RUNS Build it fast - SpaceJoist has a number of features that simplify construction, which helps a project to run smoothly, and meet deadlines: The consistent width and depth of the off-site manufactured SpaceJoists provide easier floor material installation, and the open web design allows for service runs without the need for drilling or notching. These benefits reduce the amount of time contractors spend on site, speed up construction, and ultimately save the builder money. WIDE FIXING SURFACE Build it for less - SpaceJoist s lightweight open web design provides on-site savings in labour. With no need for drilling or notching for installation of services, typical errors that incur costly remedial work is reduced. The long spans that SpaceJoist is able to achieve can eliminate the need for costly intermediate load bearing walls. The bespoke design of each SpaceJoist to fit a particular job reduces the site wastage and pilferage of timber joists. These factors among others translate into an increase in profit for your bottom line. 0

5 Features & Benefits OPEN WEB DESIGN Fast and simple installation of services, without the need for drilling or notching. LONGER SPANS Longer spans are achievable in comparison to solid timber. This may eliminate the need for intermediate load bearing internal walls, thus reducing a building s overall cost. FIGURE 0 A range of depths are available DESIGN FLEXIBILITY A number of end conditions are available to the designer, including top chord supported. Spacejoists can be designed for precisely locating bearing walls and partitions and accommodating large services. REDUCED SITE WASTAGE Bespoke design eliminates the need for site alterations. SpaceJoist also saves timber resources by reducing the amount of waste timber generated during construction. WIDER SPACING Fewer beams are required to complete a floor installation, reducing labour time. Versatile webbing can allow for larger services Ample room to run services LIGHT WEIGHT The light weight construction allows the joists to be manoeuvred easily and safely on site, often without the need for specialist lifting equipment.

28 GOOD PRACTICE:

29 Do s and Don ts on Site FIGURE 0 Do s Don ts Store as described in the Installation Guide (page ) Lift the joists in a vertical position Use the open web feature for the installation of services Protect joists from inclement weather - Do not drill holes through any part of the joist - Do not cut through the chords - Do not cut or remove the metal webs - Do not cut notches in any part of the joist Install the joists as they have been designed: Refer to the joist designer s drawings for the correct orientation, spacing etc. 9

31 Installation Guide Unloading of joists and loose timber components: At all times consideration should be given to the moisture content of the timber products. Where it is At all times the contractor responsible should considered that weatherproof protection is allocate sufficient resources in terms of equipment necessary this should be arranged so as to allow and personnel to safely undertake the relevant work proper ventilation and the free passage of air around operations in accordance with both an Approved all components.

Adequate props should be installed on both sides of vertically stored joists in order to ensure overall As a general principle, joists and associated stability and to allow the safe removal of units as components should be lifted and moved on a they are required. minimum number of occasions; the most preferred option being to unload and transfer units directly to the final level of use for immediate assembly.

The site storage of joists and loose timber components: Where it is necessary to store joists and associated timber components on site this should be undertaken with full consideration of the following matters: The proposed storage area should be level, well drained and free from vegetation. Joists should preferably be stored vertical (to minimize the risk of distortion) using suitable bearers located at positions where support has been assumed in the design. Where joists are stacked horizontally, a level support should be provided at approximately 000 mm centres. Support bearers should be of sufficient height to ensure that joists do not come into contact with the ground. Packs of bundled joists should be adequately propped or braced to ensure overall stability is maintained prior to their release and assembly. All areas where personnel are required to work shall be adequately constructed and protected in appropriate accordance with the Regulations or as assumed in the Approved Method Statement. Safe erection procedures: Only where proper and full consideration has been given to the circumstances relevant to any given site can detailed erection procedures be given. However, certain aspects of good practice are relevant across a broad spectrum of floor and roof configurations.

32 Beamed Roofs should preferably be assembled through the use of a temporary safe working platform situated no more than 00 mm below wall plate level. Under no circumstances should temporary bracing members be removed prior to permanent bracing members having been installed. Joists should not be cut or modified in any way without first obtaining approval from the Joist Designer. No cladding/decking work shall be allowed to commence until ALL permanent bracing members have been installed. Care should be taken to ensure that joists and allied components are located in their design positions and accurately spaced. Multi-ply joist units should be fixed together in accordance with the details supplied by the Joist Designer (if not undertaken at works). All roof/floor areas where a fall might occur shall be guarded by suitable and adequate edge protection in accordance with the requirements of the current Construction (Health, Safety and Welfare) Regulations.

33 TM SpaceJoist - The Fully Engineered System Spacejoist projects are fully engineered using ITW Alpine s powerful VIEW software package, which seamlessly integrates two programs; Truscad and Layout. SPACEJOISTS IN LAYOUT Complex floor arrangements can be put together in Layout to incorporate stair openings through the floor, or even chases across a run of beams for special services such as air conditioning installations. Once the beams have been added in Layout, they can be designed in a couple of clicks using the Job Designer tool. Job Designer fully analyses each Spacejoist, transferring loads onto trimmers where required. LAYOUT & TRUSCAD INTEGRATION The Truscad program provides the designer with extra flexibility for making adjustments for special services and bearing conditions etc. Also, single Spacejoists can be quickly input and designed in Truscad if required. When a floor layout has been designed, it can be viewed as a virtual reality model, which can be an effective initial checking or presentation tool. SPACEJOISTS IN TRUSCAD VIEW can now be linked to hsbcad timber frame software. This allows the user to design a whole building with wall panels, Spacejoists and roof trusses within one completely integrated package. SPACEJOISTS & ROOF TRUSSES IN hsbcad

34 MACHINERY:

35 TM SpaceJoist Fabrication Equipment OPTION - LOW VOLUME PRODUCTION RANDEK SPL78 SAW SAW REQUIREMENTS The vertical timber webs can be cut on existing machinery such as a Randek saw. PRESS REQUIREMENTS You will require a table press with platten at least 0 x 50mm with a minimum open height of 50mm. This will allow for production of beams up to 0mm deep with a single pass. A 5 tonne Birch table press or similar would be suitable. OPTION - HIGH VOLUME PRODUCTION BIRCH SINGLE SIDED FLOOR BEAM PRESS PRESS REQUIREMENTS We would suggest that you consider the Birch Double Sided Floor Beam Press for high volume production. 5
