Snap Ties are used to vertically form concrete walls that can have a wide variety of widths and heights. There are various systems you can use to create the form system you require depending on your needs. Snap ties make the installation of concrete formwork and the subsequent removal extremely easy and efficient.

What are Form ties?

Form ties (sometimes referred to as tie bolts) connect opposite faces of wall formwork to restrain the applied concrete pressures. They transmit loads in tension between stiff vertical and/or horizontal members associated with the main formwork.

What is a snap ties for concrete?

Installation: Concrete form Snap ties are basically tension members, designed to resist the lateral pressure of fresh concrete on vertical forms. When properly fitted with cones or other they hold the wall forms at the proper distance to create the desired concrete wall thickness.

Where do snap ties break off?

The snap ties have indentations along each edge which allow them to be broken off after the forms are removed with the “snapped” end of the plate being slightly below the surface of the concrete.

What is a she bolt construction?

She-Bolts are heavy duty, reusable form ties for medium and heavy concrete construction. They are used with Inside Rods or Coil Rod that can be cut in the field to any desired length based on form thickness that is required. She-Bolts are meant to be reused, but they do wear so they must be continually inspected.

What is a concrete Waler?

Walers are structural beams mounted flush to the deck of the Unifloat concrete floating dock from Bellingham Marine. They attach to the float by long rods threaded at the ends. Called “through rods,” they span the width of the float and are held in place with washers and nuts.

What are wall ties made of?

These days, wall ties are predominantly manufactured from stainless steel which is now readily available commercially and withstands corrosion from water and cement without requiring additional protection.

How do you attach snap ties to concrete forms?

Tilt the form up and secure it at the location where you’ll pour the concrete. Insert the button end of a snap tie into each half-inch drilled hole until the spreader cone hits the sheathing face. Move to the back side of the concrete form where the buttons are sticking out.

What do you use to form concrete?

While timber is most common, there are other materials that are used for concrete forms, including steel, plywood, and fiberglass. In addition to timber, there are a few other common materials used to make concrete forms.

How are snap ties measured?

Short-end (SE) Snap Ties measure 4-3/4” at each end, plus the wall thickness. Long-end (LE) Snap Ties measure 8-1/4” at each end, plus the wall thickness. Odd-end (OE) Snap Ties measure 4-3/4” at one end and 8-1/4” at the other end, plus the wall thickness.

What is a snap tie wedge?

The snap tie wedge is a holding device that is fabricated from high strength galvanized steel that is used in a double waler or double strong back snap tie forming application to ensure proper load distribution when installed correctly.
