Linear interpolation may be used for intermediate spacing and edge distances. Short video about the space distance and edge requirements for the CONFAST wedge anchor. Post-installed concrete fasteners need to be placed a minimum distance from an unsupported edge. Uses material displacement and fixed expansion to obtain holding power. So the J or leg of the anchor has to face towards the interior of the structure especially if it's hooking the rebar. : 2500, 3000, etc.) Basic loading data (for a single anchor) – with minimum edge distance Design resistance [kN] - uncracked concrete, 32 Mpa Anchor size M8 M10 M12 M16 M20 M24 Min. (See ICC Chapter 19, Table 1908.2) In residential construction, placing anchor (j bolts) for the sill plate, I have always read that it's best to stay towards the outside edge of the foundation and face the J portion towards the interior of the home. The anchor bolt edge distance, l be, is measured in the direction of the applied load from the center of the anchor bolt to the edge of the masonry.When the projected areas of adjacent anchor bolts overlap, the portion of the overlapping area is reduced by one-half for calculating A pt or A pv as shown in Figure 3. 2 0 obj Yes, 10” anchor bolts are now required with 3” square washers in any high-wind or seismic area. in.
