PROMATECT -H Single Sided Steel Stud Partition

1 PROMATECT -HSingle Sided Steel Stud Partition2 PartitionsGeneral InformationIntroductionPartitions and external walls are used to separate buildings, enclosecompartments and contain fire to provide a barrier to the passageof fire from one side or the other and are able to satisfy each of therelevant fire resistant criteria (integrity, insulation and, if the wall isloadbearing, load bearing capacity) from either side for theprescribed period. The application of Partition and external wallsystems using Promat boards covers both non loadbearing andloadbearing in commercial, industrial, institutional, residential andhigh-rise constructions, or in the restoration of existing s internal Partition systems require less material to achievesimilar fire resistant level when compared to the industry averagewallboard Partition systems.

2 The Single layer board applicationleads to simplified construction methods over other equivalentshence increased productivity and reduced overall installation Partition and external wall systems have been developed byPromat International (Asia Pacific) Ltd. to satisfy standardrequirements for intended applications. Such considerations include:Time & Cost EffectivenessSingle layer application reduces installation cost and timecompared to traditional wallboard WallsPartitions can be as thin as loads on structures compared to industry average wallboardpartition systems for equivalent fire ResistanceExcellent thermal resistance ResistantPROMATECT 100 Partition systems have been tested andassessed for impact and static loading to satisfy specification the Building Code of Australia (BCA 2006).

3 PROMATECT -Hpartition systems have been tested for resistance to impact, stiffnessand robustness in accordance with the criteria of BS5234: Part PerformanceTested and assessed to a range of standards, including ISO140-31995, ISO717-1 1996, AS1191 2002, AS/NZS , BS5821 1984and BS2750: Part 3: 1980, to meet the needs of industry. Pleaserefer to pages 6 and 7for Resistance PerformancePromat partitions and external wall systems have been extensivelytested and assessed in accordance with BS476: Part 22 andAS1530: Part 4 to satisfy the integrity, insulation and whereapplicable loadbearing capacity (structural adequacy) Design ConsiderationsThe following points are some of the factors which should beconsidered when determining the correct specification to ensurea Partition or external wall will provide the required designperformance under both fire and ambient conditions.

4 Further advicecan be obtained from the local Promat Studwork DesignThe design of studwork should be adequate for the height of thepartition. The studwork details given in the following specificationswill be suitable up to the maximum heights stated. For greaterheights the dimension of the framing members could changedepending on the factors such as movement and deflection andlocal approvals. Larger or more frequent frame sections will oftenimprove the fire and structural studwork shall be appropriately designed for the applied loads, wind load, and where applicable structural load in the case ofload bearing systems. The framing for the Partition systems must besecurely fixed back to a substrate that has an equal or greater fireperformance than the designed Partition .

5 All fixings must be non-combustible and must be those listed in the approval design shall be in accordance with the relevant British,Australian and/or International Non Loadbearing PartitionsNon loadbearing partitions and external wall systems using Promatboards can be generally divided into framing systems consisting ofsteel or timber studs and solid partitions. For Steel stud systems,selection of suitable stud size shall be in accordance with themaximum Partition height given in the stud selection tables. Thepartition systems in the following pages, where stated, are designedfor lateral loads of up to using the composite action of theframe and Loadbearing PartitionsLoadbearing capacity of featured Partition systems in thishandbook are calculated in accordance with BS5950-8: 2003 andAS4600: 1996 for load cases defined by AS1170: 2002.

6 Themaximum load bearing capacity is given in kN for a givenpartition height taking into account the reduction in Steel strength atelevated considered in this manual are for axial compression and other loads have not been taken into further information on these loads, please contact PromatTechnical DeflectionWhere differential movement is expected between the floor or beamabove the construction, and/or the floor below, it is generallyadvisable to incorporate a deflection head track to ensure unduestress is not placed upon the Partition . This also allows for thesagging and deflection a floor or structural Steel beam will sufferunder fire conditions. Even concrete floors will suffer considerabledeflection under fire if exposed for any considerable form of movement joint is also required to allow for theexpansion of the studs under fire conditions.

7 A Partition will alsobow in its centre. As the wall bows, it will naturally get shorter. Forthis reason alone, use should be made of a top track with long sidelegs. This will allow the stud to bow and as a result drop down,without the studs dropping out of the head Movement JointMovement stress from dimensional changes due to varyingtemperature or moisture conditions can cause cracking and othersymptoms of distress in partitions. Other external forces such asimpact or vibration can directly affect the structural movement ofpartitions. This movement can be controlled through a variety ofdesign techniques such as introducing perimeter relief and slipconnections to reduce the transfer of stress from the structure toother building sub-elements and/or through the use of expansionjoints, control joints and construction a Partition , expansion joints are needed when the Partition abutsa rigid mass.

8 A vertical movement joint should be located atmaximum 10m centres in long runs of Partition . However, byintroducing a control joint into a fire-rated Partition , it does createan opening for flame and temperature transmission and thereforehas to be properly treated with approved fire-stopping on following pagePartitionsGeneral Information3 Steel Frame ComponentsBoard FixingPromat boards may be installed horizontally or Steel stud Partition system, joints in the boards must bestaggered between either side of the framing with all the jointslocated at a framing member. The boards may be fixed to the studsusing Bugle head self drilling and self-tapping screws of alength appropriate for the board thickness.

9 Needle point screws arenormally used to fix boards to light gauge Steel frames up Drill point screws are generally appropriate for heavy gaugesteel frames from to solid Partition system, joints between the adjacent boards mustbe staggered by at least 300mm. First layer of the boards are to befixed to the perimeter angle with 35mm long x self-drilling andself-tapping screws. The subsequent layer of the boards is to bestitched to the preceding layer with 40mm long x laminatingscrews, as well as fixing to the perimeter a timber frame is used, Promat boards are fixed to theframework using No. 6 wood screws of a length appropriate for theboard thickness at maximum 250mm centres, a minimum of 12mmfrom the board edge. Minimum edge distance to fasteners and themaximum spacing between screw must be maintained.

10 Please referto system detail for screws spacing and external corners may be set using a perforatedmetal corner bead fixed to the board linings at not more than500mm SelectionConstruction of Promat fire rated Steel stud partitions can be achieved using Rondo stud and track components. Other Steel components ofequivalent performance can of course be used but it is the responsibility of the manufacturer of the component to substantiate equivalentperformance with the recommended At Deflection Head & FloorThe main function of the ceiling and floor tracks is to hold the studsin position until the board is fitted. They provide for a friction fit ofthe studs and also act as a slip joint to allow for any movement inthe track sections basically come in two profiles.
