Rebar materials strengthen concrete. Materials that are designed to connect concrete slabs or strengthen them further include a series of dowels, mesh panels, and tie accessories.
Dowels are designed to run through the center of a concrete slab. Dowels are used to improve the tensile strength of concrete. They are also used to adjoin two concrete sections that have been reinforced with steel. Before concrete is poured, metal dowels and thinner rebar sections will be secured inside of a concrete slab.
Dowels are used to construct parking barriers, structural columns, curbs, and other materials used in the commercial and residential building industries. The length and width of a concrete form will reflect upon the thickness of a dowel product that will be needed.
Rebar sections are rod-shaped. A series of rebar pieces are typically used to strengthen concrete. The use of many rebar pieces will ensure that concrete is adequately stabilized and that concrete will possess the same strength from one end of the concrete to the opposite end. Mesh panels may be used independently or jointly with rebar sections.
Mesh panels are accessories that are constructed of the same steel grade as the one that a rebar section is constructed of. Sometimes, mesh panels will be used to strengthen thin concrete slabs. If a thin slab will not support the use of standard rebar sections, mesh panels may be used instead. Mesh pieces will be stabilized, prior to pouring fresh concrete.
Tie accessories are used to secure rebar sections, dowels, and mesh panels. Tie accessories include ligatures and bar chairs. Ligatures are secured around a series of rebar pieces. They are designed to form a protective cage around multiple metal pieces. The compressive strength of a concrete product will remain intact, once ligatures have been used to anchor the metal pieces. Multiple rebar sections will not twist, bend, or shift.
A bar chair has long appendages hanging down from it. These appendages are constructed of plastic, coated metal, or non-coated metal. The appendages will hold rebar sections in the proper position. If rebar is going to be angled or is going to be suspended perpendicularly, the use of bar chairs will grip the ends of the rebar sections, ensuring that they do not move while concrete is being poured. Once concrete has dried, the tie chairs will continue to keep the rebar pieces sufficiently anchored. For more information on rebar accessories, contact a professional near you.
