Modular scaffolding RINGSCAFF2 Special provisions2.2 Use2.2.1 Erection and use of scaffoldingBGI 663 or equivalent local accident prevention regulations apply. Scaffolds are only to be erected, convertedor dismantled by persons who are sufficiently qualified and familiar with the design of the scaffolding system.Erection, conversion and dismantling operations must be permanently supervised. The supervisor’s specialresponsibility is also to check the condition of all components in accordance with Chapter 2.2.2.The contractor must carry out a hazard analysis prior to starting work on scaffolding.2.2.2 Condition of componentsAll components must be checked for perfect condition prior to erection. Defective components must not beused.2.3 Construction2.3.1 General remarks2.3.2 BaseComponents as listed in Chapter 2.1.4 must be used in the erection of scaffolding according to the instructionscontained in this manual. In individual cases, the scaffolding system may be supplemented by steel tubes (tobe connected with couplers) as well as battens and planks. The load bearing capacity of these componentsmust be checked in each individual case.The RINGSCAFF modular scaffolding system may only be erected on grounds with sufficient load-bearing capacity.Load-distributing supports such as planks, sleepers or structural steel beams must be placed underneaththe scaffold to stabilize it on insufficiently solid ground.Levelling blocks are necessary when erecting scaffolds on sloping ground. It must be ensured that the baseplates or base jacks rest full-face on the ground to absorb the forces emanating from the scaffold on thehorizontal plane and transmit them to the ground beneath.2.3.3 Height adjustmentFor height adjustment, the base jacks can be extended to a maximum of 0.25 m in the standard designs describedin the following chapters. Extensions above 0.25 m must be verified by separate static analyses in eachindividual case.Scafom International BV · Phone +31 495 497204 · Fax +31 495 430676 · Mail info@scafom.com21

Components that comply with the instructions in this manual andwere manufactured prior to the publication of this manual without these identification marks may also be used.2.3.9 Verification of stabilityThe stability of scaffolds erected with the components described in Chapter 2.1.4 must be verified in eachindividual case, or a structural type analysis must be submitted. The verification of stability is deemed to havebeen provided for the standard designs described in this manual.2.3.10 Standard designsScaffolds are deemed to be of standard design within the scope of these instructions for erection and use ifconstructed along the lines illustrated under point 4. They are dimensioned to cope with working loads accordingto DIN EN 12810/12811. The standard designs may only be used without further verification if the actualworking load incurred does not exceed the maximum loads listed under these norms. In the standard designsdescribed, the working loads have been calculated on the basis of 1.5 scaffolding days simultaneously.2.3.11 Divergence from standard designsIf the scaffolding system is used to build scaffolds that deviate from the standard designs described in thismanual, such divergences must be calculable in accordance with technical construction regulations andbe verified in each individual case. In doing so, other anchoring grids may also be used. Increased loads,caused by– an increase in self-weight– an increase in surfaces exposed to high winds– increased working loadsmust be taken into account down to the ground level plane and up to the tying devices. Moreover, the effect ofbuilder’s hoists and other lifting gear must be considered unless these operate independently of the scaffold.Scafom International BV · Phone +31 495 497204 · Fax +31 495 430676 · Mail info@scafom.com23

Modular scaffolding RINGSCAFF2 Special provisions2.3.12 Provisions for verification in individual casesFacade scaffolds, horizontal stiffening of decking planesThe untied vertical frames, or rows of standards, contained in tied horizontal lifts are held elastically in placeby system planks (decking) to prevent horizontal displacement at right angles to the facade.At horizontal anchorage spacing of two bay lengths, roughly the same stiffening effect can be obtained by usingmovement springs.At bay lengths < 3.00 m the spring stiffness c, depending on the decking used, is for– solid timber and steel planks c = 0.45 kN/cm,– aluminium planks c = 0.75 kN/cm,where fitting of longitudinal ledgers at deck level is dispensed with.Where system planks and longitudinal ledgers are used at deck level, a horizontal spring stiffness ofc = 1.5 kN/cm can generally be assumed for calculation purposes.Verifications on the node (Original components and combinations)Ledger/transom and diagonal connection designsDesign of theconnector headsDesign of the breaker platefor ledgersand diagonals ”K2000+“ ”Version II” ”RINGSCAFF 2005” ”RINGSCAFF 2000””K2000+“standardized under standardized underZ-8.22-64Z-8.22-64”Version II”standardized under standardized underZ-8.22-64Z-8.22-64”RINGSCAFF 2005” Design ”A” Design ”B””RINGSCAFF 2000” Design ”B” Design ”B”Design ”A”Design ”B”standardized underZ-8.22-869standardized underZ-8.22-869Design ”B”Design ”B”standardized underZ-8.22-869standardized underZ-8.22-86924Scafom International BV · Phone +31 495 497204 · Fax +31 495 430676 · Mail info@scafom.com

Modular scaffolding RINGSCAFF2 Special provisionsSystem assumptionsThe structural system for calculation must be modelled according to Appendix 26. The short bars between thestandard tube and the point of connection as specified here are assumed to be rigid. The indices given hereunderrelate to a local coordinate system, where the x axis represents the ledger axis and the z axis the standardtube axis (see Appendix 26).In the verification of the scaffolding system it must be ensured that the moment of deflection in the connectionsbetween ledgers and standards is calculated on the outer edge of the standard tube, and that the eccentricconnection of the vertical diagonal is taken into account according to Appendix 26. The twisting moment aroundthe standard tube resulting from the horizontal component in the vertical diagonal connection is transmitted bythe node and must be verified in the ledgers.Only normal forces, transverse shearing forces and moments of deflection may be transmitted in the standardtube and ledger/transom plane, and in the plane at right angle to this plane only transverse forces may betransmitted.If it is not ensured that only components from one system are used in a scaffold, or that the influence ofall components is recorded in detailed calculation and planning documents, the scaffolds must be verifiedaccording to the specifications given below.– Load capacity verification, maximum stiffness: Specifications for design ”B”– Minimum to medium stiffness: Specifications for design ”A”Only normal forces may be transmitted by connections of diagonals.RiegelanschlussBending under loadBending in the vertical planeIn the verification of scaffolds, the design of ledger connections in the plane formed by the standard tube andthe ledger (vertical plane) , with torsion spring connections according to the torsion moments/rotation angles,(My/)-ratio according to appendix 24 and 25, fig. 1 to 6, must be taken into account.If the ledger connections are not considered as elastic, the verification of scaffolding systems may be calculatedon the assumption of medium stiffness for the torsion spring, if the following additional verifications arecarried out:For the most unfavourable combination of loads, the verification of load-bearing capacity in all ledger connectionsmust be carried out on the assumption of minimum torsion spring stiffness, deviating from DIN 4420 byinserting the factor yF= 1.15. At the point of the maximum ledger connection moment, marginal values basedon minimum and maximum torsion spring stiffness must be calculated. The calculation of marginal values maybe carried out on simplified, localised systems.Scafom International BV · Phone +31 495 497204 · Fax +31 495 430676 · Mail info@scafom.com25

Modular scaffolding RINGSCAFF3 Erection of RINGSCAFF modular scaffolding3 Erection of RINGSCAFF modular scaffoldingThe erection of scaffolding must be carried out in such a way as to minimize the danger of falling. Prior tostarting work a hazard analysis must be carried out and appropriate steps taken to minimize the danger ofaccidents.It is the task of the person responsible for the assembly and dismantling of scaffolds to takeappropriate measures to prevent accidents and the consequences of such accidents for the lives andhealth of the victims, according to the feasibility and suitability of such measures and the actual riskinvolved, which provide greatest possible security. Where possible, collective protective measures musttake priority over individual measures.SCAFOM recommends securing the assemblymen engaged in erecting, dismantling or converting modularscaffolding against falling by personal safety equipment (PSE).The PSE may only be fastened to the following components of RINGSCAFF modular scaffolds:– free-standing individual standards, the bottom joint of which is at least 50 cm below a closed ledgerplane– Ledgers up to 3.00 m in length, which are connected to two standards, the bottom joints of which areat least 50 cm below a closed ledger plane– Ledgers up to 3.00 m in length, which are part of a closed, horizontal, rectangular ledger system– Toe boards, diagonal braces, planks and tele-ledgers are unsuitable for fastening such devices.The user is free to choose alternative accident prevention methods, as long as these guarantee an equivalentdegree of safety.Scafom International BV · Phone +31 495 497204 · Fax +31 495 430676 · Mail info@scafom.com39
