After framers have finished framing the structure, the structure then needs to have tie-down hardware installed. ICG’s tie-down crew installs all hardware below the trusses, including truss screws and clips, hold-downs, plate anchors, as well as interior and exterior straps. Tie-down installation is an important part of building homes that are subject to any notable overturning or uplift momentum. The need for these components is especially prominent in coastal regions. Florida homes that are built after 2001 are required to have hurricane tie-down. The purpose of hurricane ties is to secure connections between the roof and walls, and hold-downs secure the walls to the foundation, providing resistance to uplift and lateral forces that could damage the structure. All these components work together to secure the load paths and structural connections of each structure. There are many types of ties that are determined by the connection types and load ratings. Each piece of hardware installed is based on the structural plans to ensure resistance to uplift, overturn, and sliding forces. Reading structural plans is an integral skill for tie-down crew members as they must be able to find the proper callouts and designations and pay close attention to the type and number of fasteners required.
As a Tie-Down Installer, you get to learn about and use innovative technology applications to install tie-down hardware efficiently and safely such as the Simpson Quick Stik™ for rafter fastening and Hilti vacuums to combat silica particles. Another requisite of tie-down installer employees is proficiency in reading and using both Simpson and USP load tables. This skill aids in making informed decisions and understanding the wide variety of applications, purposes, load force directions, and even proper fastener selection. The load tables show each model number, fastener type, and allowable loads. By knowing how to read load tables you can utilize the information to substitute hardware when needed. Once a tie-down job is completed then the structure can progress through the rest of the inspection and finish processes.
