![]() ![]() Powder-actuated tools are designed to drive fasteners, specifically designed for deck attachment, through the sheet metal decking and into the base steel. In accordance with ANSI/ASSE A10.3-2013, operators must be trained by the tool manufacturer or other authorized party. We strongly advise that only qualified operators use powder-actuated tools while working on-site. For deck that is intended to end lap, usually seen on roof deck, the end lap location should be adjusted so the center of the lapped portion occurs over the support or, when supported by bar joists, over a top chord member. ![]() In the unusual case there is less than 1 ½” of bearing, additional fastening should be provided and the deck web crippling capacity should be inspected. A minimum of 1 ½” of end bearing should be provided for deck unless noted otherwise on the deck installation drawings. ![]() Important: No substitution of fastener type or pattern should be made without the approval of the designer.ĭeck fastening to the structural frame can be accomplished with self-drilling screws, welds, powder-driven or air-driven fasteners. Proper alignment can only be achieved by proper adjustment of each deck panel while it is being placed because cover width errors across the bay cannot be corrected with the last sheets in the run. Flutes that do not align can create closure problems that may interrupt the slab design. Roof deck is usually left exposed on the bottom and the rib alignment has to be parallel to the girders at all girder lines to prevent unsightly conditions.įloor deck flutes should, if permitted, maintain alignment to achieve continuous concrete ribs across abutting sheet ends, to minimize concrete leakage. Often the deck is used as part of the horizontal bracing system and the fastening method and pattern have been selected to provide a certain strength and stiffness in the plane of the deck. In order to have your deck perform its design functions and serve as a working platform, it must be properly attached. ![]() This minor effort at the time of deck placement eliminates the need for field corrections. On-site experience has shown that the frequency of snapping a chalk line determines the accuracy of rib and flute alignment. We recommend using a snap chalk line at reasonable intervals to assure proper alignment of deck panels before starting any installation. At the same time, it’s important to maintain the rib or flute alignment across the whole structure while also keeping in mind that panel cover widths must be maintained in order to achieve long straight runs of deck. The beginning point of the installation should be carefully selected for proper deck orientation and the edge of roof or floor slab location. At CSM Products & Solutions, we reinforce that deck must be installed by qualified and experienced workers. Metal deck is always installed in accordance with the “Approved for Construction” drawings presented by the designer of the project. This is typically noted on the structural drawings or specifications of the scope of the project. The Engineer of Record will ultimately determine the required fastening type and pattern.
