What is HRC rebar?
HRC 555 headed reinforcing bar is a deformed or plain steel bar with a head attached to one or both ends. The use of Headed Reinforcement improves the form, fit and functional performance of reinforced concrete structures at a low cost. …
What is a headed bar?
A headed bar is a deformed steel bar with a head attached to one, or both ends of the bar. Headed bars can be used as a replacement for straight or hooked bars in concrete members and connections.
What are headed steel bars?
A headed bar is either an oversized coupler, plate, or head attached to one or both ends of a deformed rein- forcing bar. Heads may be attached through mechanical means or integrally forged from the bar material itself.
What is headed reinforcement?
Headed reinforcing bars are standard lengths of reinforcement with heads (rectangular steel plates) attached at one or both ends, generally by means of friction welding. The size of the plate is chosen so that the bar is fully anchored by bearing of the plate on the surrounding concrete rather than by bond.
What are headed links?
Headed Bars are a simple and effective alternative to hooks and long development length. A compact disc is mounted onto the reinforcement bar end. The assembly of the rebar and the anchor provides a anchorage superior to long straight or bent reinforcement bars, while being simpler and faster to install.
What is rebar used for?
A. Reinforcing bar, or rebar, is a common steel bar that is hot rolled and is used widely in the construction industry, especially for concrete reinforcement. Steel rebar is most commonly used as a tensioning device to reinforce concrete and other masonry structures to help hold the concrete in a compressed state.
Is rebar a code?
IS:2502-1963: Code of practice for bending & fixing of bars for concrete reinforcement. IS:2751 -1998: Recommended practice for welding of mild steel plain & deformed bars for reinforced construction. IS:5525 -1969: Recommendation for detailing of reinforcement in reinforced concrete works.
Is Lap length a code?
The Code (IS Code 456-200 Page No- 45, Cl. 26.2. 5.1c) specifies a lap length of 2Ld in situations where the member is subjected to direct tension. In no case should the lap length be less than 30Ø under flexural or direct tension and 24φ under compression.
Which bar should be Joggled in coupler joint?
On the construction site, always the top bar of the column is joggled for the lapping purpose.
How close should rebar be spaced?
approximately 12 inches
Place rebar in a grid pattern with a spacing between bars of approximately 12 inches. In either case, blocks should be used under the reinforcement to keep centered within the concrete. Synthetic fibers have also proven to be beneficial in driveways as a way to reduce shrinkage cracks.
