How close to the edge can you put a concrete anchor?
How close to the edge can you put a concrete anchor?
To avoid these disasters, don’t drill any closer than 4 in. from the edge. If there’s no other option, turn off the hammering action on the drill. Also, avoid wedge-type anchors.
What is the minimum number of anchor bolts required for anchoring a 12 foot section of wood sill plate to a foundation?
two bolts
There shall be a minimum of two bolts per plate section with one bolt located not more than 12 inches (305 mm) or less than seven bolt diameters from each end of the plate section.
What is minimum edge distance?
On the other hand, the minimum edge distance (cmin) is defined as the minimum distance from the center of an anchor to a free-edge of the base material based on testing requirements of ACI 355.2/355.4.
How many anchors sill plate?
Remember that anchors must be placed a minimum of five anchor diameters from any unsupported edge, and there should be a minimum of ten anchor diameters between any two anchors. Using a hammer drill, drill your holes using a carbide-tipped masonry bit.
How far apart do I put anchor bolts in concrete?
Placement is approximately every 6 to 8 feet depending on code, with one not more than 12 inches from each end of a wall bottom plate. Make sure not to put a J-bolt in the middle of a doorway. Hammer an 8d nail on the outside of the concrete form to mark the J-bolt positions.
What is the maximum spacing for anchor bolts on a sill plate?
Anchor bolts shall fasten sill plates to the top of concrete or masonry walls a maximum of 4 feet (1,219 mm) on center. EXCEPTION: Sill plate anchor bolts shall be spaced a maximum of 6 feet (1,829 mm) on center when installed on foundation walls retaining less than 7 feet (2,135 mm) of unbalanced fill.
What is the maximum spacing for the anchor bolts?
4 feet
The maximum anchor bolt spacing shall be 4 feet (1219 mm) for buildings over two stories in height. Stepped cripple walls shall conform to Section R602.
How far should a bolt be from an edge?
Minimum edge distance (distance between centre of the bolt hole to the plate edge) shall not be less than 1.25 times the nominal bolt diameter.
What is the edge distance of bolt?
Minimum Edge Distance, in. (Center of Standard Holea to Edge of Connected Part)
| Nominal Bolt Diameter (in.) | At Sheared Edges | At Rolled Edges of Plates, Shapes or Bars Gas Cut or Saw-cut Edges b |
|---|---|---|
| 7/8 | 1 1/2c | 1 1/8 |
| 1 | 1 3/4c | 1 1/4 |
| 1 1/8 | 2 | 1 1/2 |
| 1 1/4 | 2 1/4 | 1 5/8 |
What is the spacing of anchor bolts from ends of sill plates?
Interior braced wall plates shall have anchor bolts spaced at not more than 6 feet (1,829 mm) on center and located within 12 inches (305 mm) of the ends of each plate section where supported on a continuous foundation.
What is the edge distance of an anchor bolt?
Anchor bolt edge distance 1.75 inches or 2.75 inches, dependent upon sill plate
What size bolts do you use for sill plate anchor?
Sill plate anchor requirement. For a wall subjected to wind pressures (positive and negative directions), this 4D requirement technically prevents the use of 1/2″ diameter bolts in a 2×4 sill plate, since half of 3.5 inches is less than 4D distance. Of course, 1/2″ and even 5/8″ bolts are commonly used as anchor bolts.
What is the minimum edge distance for a wood sill plate?
Have a basic question regarding wood sill plates for which I can’t seem to track down an exact source. According to NDS Table 8.5.3 the minimum edge distance for a bolt loaded perpendicular to grain is 4D for loaded edge and 1.5D for unloaded edge.
What is the minimum bolt edge distance and spacings?
Here is a strange “What was the Code thinking?” question… In the NDS spec, section 11.5.1 deals with minimum bolt edge/end distances and spacings. 11.5.1.3 and Table 11.5.1.C states that the minimum edge distance needs to be 4D from the center of a bolt. So this begs the question, what do you do with 2×4 wall sill plates?
