Floor Joists

Getting ready to build your dream home or next project? That’s great news. Every project has its own requirements, including attaching floor joists to wall frames. The First thing that you should consider is to get help and guidance from a manufacturer of timber roof trusses and wall frames. They will quickly help you with the ‘what’s’ and the ‘how’s’ of construction for your project.

How are Floor Joists Attached to Wall Frames?

When building a house or any type of structure, one of the most important aspects is ensuring that the floor is sturdy and secure. This is where the floor joists and wall frames come into play. In this blog, we’ll discuss how floor joists are attached to wall frames and the various methods used to ensure a strong and stable structure.

The Basics of Floor Joists and Wall Frames

Before we dive into how they are attached, let’s first review what floor joists and wall frames are. Floor joists are horizontal structural members that span from one wall to another and support the weight of the structure above. They are typically made of wood, steel, or engineered wood products. Wall frames, on the other hand, are vertical structural members that make up the walls of the structure. They are also typically made of wood or steel.

Attaching Floor Joists to Wall Frames

There are several methods used to attach floor joists to wall frames. The most common methods include:
  1. Joist hangers
  2. Toe-nailing
  3. Simpson Strong-Tie connectors

Joists Hangers

Joist hangers are metal brackets that are fastened to the wall frame and hold the ends of the floor joists. They provide a secure and easy way to attach the joists to the wall frame. The joist hanger is nailed or screwed to the wall frame, and the floor joist is then placed inside the hanger and secured with nails or screws. Joist hangers come in various sizes and shapes, depending on the size and orientation of the joists.

Toe- Nailing

Toe-nailing is a method of attaching the floor joists to the wall frame by driving nails at an angle through the joist and into the wall frame. This method is usually used for smaller structures or where the joist hangers are not available. While toe-nailing is a simple and easy method, it may not provide the same level of strength and stability as joist hangers or other connectors.

Tie- Connectors

Simpson Strong-Tie connectors are metal brackets that are specifically designed to attach the floor joists to the wall frame. They provide a stronger and more secure connection than toe-nailing and are often used in larger and more complex structures. These connectors are attached to the wall frame using nails or screws, and the floor joists are then placed inside the connector and secured with nails or screws. Simpson Strong-Tie connectors come in various sizes and shapes, depending on the size and orientation of the joists.


Attaching floor joists to wall frames is an essential step in building a sturdy and secure structure. While there are several methods to accomplish this, the most common methods include joist hangers, toe-nailing, and Simpson Strong-Tie connectors.
