For many years the inadequate usage of spaces and chairs has been a major cause of misplaced steel reinforcement and decreased durability of in-situ reinforced concrete. Until now no comprehensive national recommendations have existed either for the use or the performance of spacers. HawkeyePedershaab Spacers and. Reinforcement Accessories for Virtually Every Concrete Product. HawkeyePedershaab is the source for reinforcement spacers and accessories. Over the years we have developed a full family of. spacers and accessories, both metal and plastic for virtually every.

Spacers for Spiral Reinforcement Temperature-Shrinkage Reinforcement Slabs, Walls, Mats, or Footings Bar Spacing Joists Adjoining Beams or Walls Corner Bars Bar Supports Side-Form Spacers Welded Plain or Deformed Wire Reinforcement Post-Tensioned Construction Placing Facilitation. CHAPTER 6. Concrete Spacers From Precon Products. We have a wide choice of block spacers in a range of sizes. They also come in a choice of pack sizes, from to 1, These will provide heavy-duty and accurate reinforcement within the formwork. Stable concrete meshblock spacers are ideal for supporting reinforcing bars above membranes.

Automatic reinforcement spacer/stirrup. The Spa-Stir automatically locks two cages into an integral unit of reinforcement and spaces from a single form surface to achieve the proper concrete cover.

The market leaders in steel reinforcement, buildability, innovation and dedication to its customers and service Concrete, Plastic and Wire Reinforcement Spacers. The spacers remain in-situ throughout the construction process allowing the reinforcement to become encased in concrete.

When installed correctly at the appropriate centres, the use of reinforcement spacers, ensure that the correct cover between the reinforcement and formwork is maintained. A rebar spacer is a device that secures the reinforcing steel or "rebar" in reinforced concrete structures as the rebar is assembled in place prior to the final concrete pour.

The spacers are left in place for the pour to keep the reinforcing in place, and become a permanent part of the structure. The main categories of rebar spacers are. Spacer Products. Varicage spacers. Heavy duty varicage spacers. Stirrup spacers. Snap spacers. K-Klip II spacers. Heavy duty "V" nose spacers.

Box section spacers. Eastern States Steel Corporation is a leading supplier of wire reinforcement spacers for reinforced concrete pipe, box culverts, and other reinforced precast concrete products. Spacer cube shaped for slab reinforcement.

Connection of spacer and steel rebar: There are 3 options for connection between spacer and steel rebar: Spacers are placed on horizontal surface and support the steel rebar above.

By the weight and fixation of steel mesh then the spacers can be fixed without the binding connection.

Reinforcement spacers with plastic protected leg tips are often 20 to mm high, it ensures consistent placement of reinforcement in slabs, requires no adjustment after pouring concrete, and prevent the wire spacer sinking into the ground.

They are widely used to support reinforcement bars at determined heights in a concrete slab. Since the reinforcement chair supports only the top mesh reinforcement, the bottom mesh reinforcement needs as well as support to maintain its concrete cover.

Likewise, a spacer is required. There are so many types of spacers that can be used during site construction, but the most commonly used at the site is the concrete spacer. The fast, accurate and safe way to position mesh reinforcement K-Klip Spacers.

At first glance, the book appears to be an atlas of schedules. And so it is, the most exhaustive in existence. The first comprehensive guidance on spacers was probably Concrete Society Report CS in Prior to that, it was not uncommon to use any material available on-site including bricks, tiles, broken concrete, and timber pieces to support r practise was to use site-made cement mortar blocks as spacers, but this practise was stopped in BS because of poor.

reinforcement spacers or rebar spacer. The spacers ar left in situ for the pour to stay the reinforcing in situ, and become a permanent a part of the structure.

The main classes of rebar spacers are: Linear Spacers (Π-section profiles, H-section profiles, or other 3 dimensional shapes). The Reinforcement Handbook provides information about the use of steel reinforcement when embedded in ‘plain’ concrete, in normal reinforced concrete or in prestressed concrete.

Other information includes guidance on some applicable Australian Standards, design and construction tolerances, fabrication of reinforcement and tabulated data on. spacers and custom wheels in the industry. Unverferth ® Ag Wheel Specialist Hubs/extensions Regardless of tillage preference or row width, Unverferth has the extensions you need to center wheels down the middle of the row.

Plastic line spacers come in 2 metre lengths and are usually used in flooring applications where covers are small.

This spacer is also known in the industry as “Trick-Track”. Clampfix. This spacer is a more general clip on plastic spacer and these days is rarely used.ShaftSpacer® rebar spacer wheels properly position reinforcement cages every time. ShaftSpacer® rebar cage spacers are a snap to install with minimal cost and installation time.

These durable, high-density drilled pier spacers are built for drilled shaft construction and provide assurance for the driller, contractor, engineer and inspector.The minimum spacing between two reinforcement bars should be at least equal to the maximum coarse aggregate dimension plus a margin of 5 mm.

For Greece, the maximum aggregate grains dimension for usual concrete, is 32 mm and for self-compacting concrete is 16 mm.
