Joint assembly for a one-hour fire wall perpendicular to a two-hour firewall. The walls are separated by a three-inch expansion joint. The one-hour wall terminates at roof deck above, but the beam supporting the roof penetrates the one-hour wall (perpendicular to the one-hour wall, running parallel to, and three inches from the two-hour wall). The two-hour wall continues vertically higher than the roof that terminates the one-hour wall.
Is there a joint assembly similar to WW-D1090 (the closest Hilti assembly is a WW-D-0068 but it has a max width of 2-inches) that can abut a penetration assembly similar to a W-L-7188? Refer to attachments.
Hello!
I wanted to let you know we don't have an exact system to address this application. We however can address your application through an Engineering Judgment which will be a custom detail showing your exact application with the firestop components required to maintain the stated ratings. If you would like to get an engineering judgment, please follow the information below for submitting a request.
We are proud to announce the launch of the HILTI CONSTRUCTION PLATFORM (HCP), our company’s new engineering service website. This platform will be the home for all of your Fire Protection Design needs. Instead of emailing a PDF form for a request, the platform enables you to create new Engineering Judgment (EJ) requests, submit revisions to previously completed EJs or connect with an FPE on a question. HCP also enables you to track the status of your request.
You can find more information on how to access this new platform here: http://www.hilti.com/ej (US) or http://www.hilti.ca/ej (Canada.) If you have any questions or require assistance navigating the platform, please call Customer Service for help at 1-800-879-8000 (US) or 1-800-363-4458 (Canada.)
Along with HCP, Hilti is excited to announce our new mobile app for all your firestop needs: Hilti Firestop Selector. Using the Firestop Selector app gives you easy access to the Hilti Fire Protection Design Team from the jobsite, on the road, or in the office to request a new EJ, an EJ Revision, or a Question anytime, anywhere. You can download the app using the appropriate link below.
