Set them at the required height and depth.Once all anchor bolts are positioned in place, pour the concrete into the concrete form. Code Calculators automatically generates a detailed list of requirements. Bolt spacing is also reduced to 4 feet for anchorage of three-story buildings. Increasing the diameter to 5/8 inches is usually a good way to allow for some margin of error, particularly in seismic regions.

For example, if using a 5/8″ anchor bolt, use a 5/8″ diameter drill bit.The depth of the drill-hole should be a bit longer than the length of the anchor bolt to allow for some leeway. Form with a sonotube and fill with concrete. 0000009190 00000 n As with maximum spacing, this is a minimum requirement. Insert anchor bolts before the concrete sets.

Some of the more commonly used types of anchor bolts include:The type of anchor used depends on whether it is cast-in-place during concrete or grout pour, or whether it is fastened after the concrete has cured. Additionally, admixtures, if added to the concrete, can also affect the cure time.Generally speaking, however, concrete should cure within 3 to 7 days. After drilling the hole, dust off all the debris creating during the drilling.

Be sure to set the drill to hammer mode. While sizing requirements vary according to local code, 1/2 inch diameter, embedded at least 7 inches, is usually the minimum. Measure the distance between the anchor bolts and the distance from the anchor bolts to the foundation's edge. Alternatively, you can wrap tape around the drill bit to use as a reference.Be sure to use ear and eye protection during drilling. 0000005292 00000 n Allow the concrete to flow into the anchor bolts, stopping at the right level set by the concrete form.Once the concrete has cured, the anchor bolt holders and concrete form can be removed. 0000007409 00000 n 0000000896 00000 n Interior bearing wall sole plates shall have anchor bolts spaced at not more than 6 feet (1829 mm) on center and located within 12 inches (305 mm) of the ends of each plate section when supported on a continuous foundation. The embedment length of headed bolts, lb, is measured parallel to the bolt axis from the surface of the masonry to the bolt head bearing surface. Calculate Code Requirements He holds a Bachelor of Arts in theater arts from Humboldt State University. Also, a bolt must be placed within 1 foot of the ends of each piece (as shown in fig. The minimum embedded depth is 7 inches (178 mm) and the minimum diameter required is 1/2″ (12.7 mm).These are minimum requirements, however, which is why designers often will decrease the spacing requirement or increase the diameter of the bolt in order to allow for a margin of error. Interior bearing wall sole plates shall have anchor bolts spaced at not more than 6 feet (1829 mm) on center and located within 12 inches (305 mm) of the ends of each plate section when supported on a continuous foundation. 0000002694 00000 n Use a loop or ring nut if using cables to secure your shed to the anchors. There are different building code requirements on bolt diameter, length, and spacing for new construction versus retrofit construction. Unusual building designs might require more bracing than conventional wood-frame construction. In addition to embedded depth, the minimum diameter required for anchor bolts is 1/2 inch (12.7 mm) per the International Building Code (IBC). The length of the anchor bolt is found in the specifications; the spacing and location of the bolts are shown on the drawings. 0000001234 00000 n As with maximum spacing, this is a minimum requirement. It should be OK to drill into the concrete to set your anchor bolts in place after this period of time.Bolts are also required to extend a minimum of 7 inches (178 mm) into concrete or grouted cells of concrete masonry units.
