The attached brochure will assist in determining the proper metal expansion joints and piping components. As the temperature rises or the moisture content of the concrete increases, expansion takes place. Concrete Expansion Joints. Joint type and spacing will vary with each project according to the kind of structure, climatic conditions, and anticipated stresses in the concrete. FIBRE EXPANSION JOINT is ideal for use on highways, streets, airport runways, sidewalks, driveways, flatwork, and scores of commercial and industrial applications. Whether cracks occur due to shrinkage when curing, or because of frost, seismic movement, or ground settling, it is best to encourage them to occur where you want them.
Pours resting on the ground, like driveways, patios, sidewalks, stairs, and slab-on-grade, typically only require expansion joints where they come in contact with other solid structures, each other, or where length dictates a joint is appropriate. Dual bellows units with center anchor base are rated for 8", 12", or 16" of axial travel. Metal expansion joints for concrete5.org. Expansion joints are often used where one mass of concrete meets another solid mass like a building, bridge, pool, or other structure, or where the length can be affected by expansion.

Placement should be 2 to 3 times in feet the concrete's thickness in inches, so every 8' to 12' for a 4" thick pad. Thinner joints (1/4″, 3/8″, or 1/2″) (6. In effect, stainless steel expansion joints are used to maintain building assembly functions while allowing the individual parts to move without problems. As the length between the bellows increases, the spring rate decreases. Metal expansion joints for concrete knives. Availability: On stock. Stainless Steel 304 / Polished. Advantages: - QuicKey™ is the only galvanized joint system that features knockouts for square dowels, which provide better load transfer over round dowels and also reduce edge curl of the slab.
Lightweight, flexible foam … forms or wraps around curved or circular surfaces. Select a joint with the height matching exactly the tile thickness, the joint must not rise above the level of covering...
