The beveled head of the askew head bolt engages the internal wedge shape of the insert and produces an automatic tightening action when a load is placed on it. Lay out the wall and excavate the slope and the footing trench. When the forms are stripped, the open face of the insert is flush with the concrete. Nail holes in the back of the insert allow easy nailing to forms. Whether youre pouring a foundation, patio, or driveway, our calculator provides accurate results in both imperial and metric units. Our intuitive calculator simplifies concrete volume and rebar estimations, ensuring efficient and cost-effective construction. It typically is installed in a poured concrete footing or base for the concrete block wall, set into the concrete for the depth of the footing and spaced so holes in the blocks will go over the rebar, to be secured with concrete grout. Effortlessly determine the exact concrete and rebar quantities for your project. Concrete Inserts BLOK-LOK Concrete Wedge inserts are embedded into concrete slabs. Rebar is placed in walls both vertically and horizontally, depending on the type of wall and the forces on it.They are placed where cracking is likely to occur due to excessive tensile stress. Control Joints Control joint products are used to reduce restraint and permit longitudinal movement.An important application of stress distribution joint reinforcement is to safeguard the integrity of masonry walls from unexpected and difficult-to-design-for events such as industrial explosions and accidents. Stress Distribution – Continuous joint reinforcement is used to distribute stress concentrations that occur above and below windows, or where wall sections are reduced because of embedded columns, and below concentrated loads such as beams and slabs. (as in example diagram) Multiply the 2 different side lengths of each rectangle to find individual areas, then add them together to find Total Slab Area. To calculate Total Area of a multi sided slab, first divide the shape into rectangles or squares.
Wall Intersections – Partition-Lok® and Corner-Lok® are prefabricated pieces of corner and tee joint reinforcement used to join masonry walls at intersections and corners. Calculate Rebar Quantity and Mesh From Total Slab Area and Perimeter. Applications of Joint Reinforcement Reinforced Masonry – Joint reinforcement either alone or in conjunction with wider-spaced bond beams contributes to the area of steel requirements in reinforced masonry. Table A (page 2) shows wire size and properties for steel joint reinforcement material. For joint reinforcement to effectively distribute stress it must be adequately bonded through the mortar so that the masonry and reinforcement act together. Joint Reinforcement Joint reinforcement is installed in horizontal mortar joints of masonry for shrinkage stress control.Flex-O-Lok® Ties Adjustable ties are recommended as a veneer or cavity wall tie to connect to structural steel.
