Definitions

• a modular platform comprises a plurality of truss frames of the type described above.
• the platform includes means for fastening the top rails of adjoining truss frames together so as to form a continuous top chord in a direction parallel to that spanned by the connected truss frames. It also preferably includes means for connecting the bottom connections of the truss frames together so as to form a bottom chord which extends in a direction parallel to that spanned by the connected frames.
• the modular platform may further comprise filler panels located between predetermined ones of the truss frames.
• Fig. 2 is an oblique view in side elevation of the truss frame shown in Fig. 1;
• Fig. 3 is a plan view schematically illustrating a portion of a first embodiment of a scaffolding platform assembled in accordance with the modular concept of the present invention;
• truss frame 10 When truss frame 10 is utilized to provide a support surface, truss frame 10 further comprises decking 42 mounted to top rails 12 so as to form a substantially continuous surface thereon.
• decking 42 For the embodiment illustrated in Fig. 1, corner members 44 of truss frame 10 protrude slightly above the level of rails 12, but not above the level of decking 42, so that the supporting surface provided by decking 42 is substantially flat.
• decking 42 may be cut to fit closely around each corner member 44. With corner members 44 and decking 42 configured in this manner, decking 42 is constrained from movement in a plane parallel to " the plane containing top rails 12.
• Decking 42 may also be restrained from upward movement, in a direction which is perpendicular to a plane containing top rails 12, by any suitable means, such as, for example, gluing or screwing decking 42 to top rails 12.
• Any suitable means such as, for example, gluing or screwing decking 42 to top rails 12.
• One especially convenient means for restraining decking 42 from movement in an upward d irection is to fasten decking 42 to bracing members 14 b y tie wires 46 which are threaded through apertures 48 in d ecking 42 and fastened around bracing members 14.
• Decking 42 may be chosen from a wide variety of materials which meet the reguirements of a particular application.
• One convenient material for decking 42 is plywood, the thickness and grade quality .of which can be chosen to accomodate the strength requirements and environmental conditions of the application involved.
• Top rails 62, bracing members 64 and bottom .connection 66 are further disposed so as to form the shape of an inverted pyramid.
• truss frame 62 is very similar in structure to truss frame 10 shown in Fig. 1, the major difference between the two being that truss frame 10 includes corner braces 56 whereas truss frame 60 does not.
• the modular platform of Fig. 3 further comprises means for connecting together top rails 62 of adjoining truss frames 60 so that top rails 62 form a continuous top chord in a direction parallel to that spanned by the connected truss frames 60.
• connecting together top rails 62 of adjoining truss frames 60 and 70 in Fig. 3 provides the platform with a top chord between frames 60 and 70 in a
• bottom connections 66 of adjoining truss frames are connected together by linking members 36.
• Opposite ends of each linking member 36 are attached to the respective bottom connections by means of a bolt or other fastener inserted through apertures 28 in bottom l -' connections 66.
