33、etal planks should be fixed or contained so that they cannot move on their supporting members.Planks can be used in traditional structural platform layouts, provided that the spacing of supporting beams, or purlins, is adjusted to suit the spans of the planks. It is preferable to stagger the planks

34、as described in A.2 (see also Figure A.1). The staggered layout provides maximum strength and rigidity. However, the in-line layout described in A.3 (see also Figure A.2) is simpler than the staggered layout and allows large composite panels to be assembled and raised into position as one unit. A.2

35、Fixing A.2.1 Staggered layoutWherever practical, joints between planks should be placed at a distance that is approximately equal to one-quarter of the span of the plank on either side of the supporting members (see Figure A.3). However, at the extreme ends of a platform or floor, any joints should

36、be placed three-quarters of the plank span in from the end in order to give maximum strength.It is essential to bolt individual planks through the side flanges to adjacent planks at both ends and in the centre of each span between joints. Where joints occur along the side of a platform or floor, spl

37、icing pieces should be bolted to the inside of the perimeter flanges (see Figure A.1). Where planks cross supporting beams or purlins, they should be secured to the supporting member using a cleat see Figure A.3a) and Figure A.3b). The cleat should be positioned alternately on each side of the suppo

38、rting member across the structure (see Figure A.1).A.2.2 In-line layoutJoints should be made directly over the centre of the supporting beam or purlin, with each plank having a minimum bearing of 25 mm. Cold form metal planks should be secured together in the centre of each span and at the ends, as

39、described in A.2.1. End bolts can be used to secure cleats for fixing each pair of plank ends to the supporting member see Figure A.2 and Figure A.3a).A.3 Planks used as stair treadsFor typical details of cold form metal planks used as stair treads, see Figure A.4.
