Abstract:
A metal roofing system includes at least one roof clip including a base portion secured to the upper portion of the at least one purlin, and flanged legs extending from opposite sides of the base portion, and a thermal spacer washer assembled between the at least one roof clip and the at least one purlin.
Abstract:
An apparatus for propelling a carriage along a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement, and method of using same are disclosed. The apparatus includes a carriage movable along the length of the purlins for dispensing a support sheet from a roll for support of insulation material as the carriage travels along the length of the purlins so that the support sheet depends from the top portion of adjacent purlins. The apparatus further includes a puller assembly attached to the carriage. The puller assembly includes a driven wheel frictionally engaged with a surface a purlin, and a drive mechanism for rotating the driven wheel.
Abstract:
A controller for propelling a carriage along a plurality of purlins, and method of using same are disclosed. A plurality of carriage sections are joined to form a continuous carnage spanning a plurality of purlins. A plurality of puller assemblies are attached to selective ones of the carriage sections. A controller is connected to the plurality of puller assemblies. The controller can be actuated to a master control mode which simultaneously engages the plurality of puller assemblies, thereby propelling the carriage along the purlins. The controller can also be selectively actuated to a selective mode which engages one of the puller assemblies.
