Admixture |
A material other than Portland cement, aggregate or water that is added to concrete to modify its properties |
Aggregate |
Materials such as sand, stone and gravel used to make concrete. |
Assemblies |
This is where a pin and clip are put together and installed as one. |
Cement |
One of the ingredients of concrete. Most cement used today is Portland cement, which is made from limestone mixed with shale, clay or other material. |
Center Punch Test |
A procedure to follow when testing the suitability of a base material to use a powder actuated system. |
Center-to-Center Spacing |
The distance between the center of one pin to the center of another pin. |
Codes |
The enforceable standards and requirements covering the methods and materials used in all phases of construction projects. |
Combination Load |
Both tensile and shear loads being applied to a fastening at the same time. |
Compressive Strength |
The ability of concrete and masonry to withstand certain levels of pressure. The compressive strength of concrete is measured in pounds per square inch (psi). |
Dead Load |
Permanently in place and supported by the structure during its life |
Edge Distance |
The distance from the center of a fastener to any physical edge. |
Fish Hook |
After the tool is actuated, the pin looks like a "Fish Hook." There is usually no holding power with a pin that has this bend. |
Flute |
The orange material on the pin used to hold the fastener in the muzzle bushing of the tool and to keep it centered. |
ICBO |
International Conference of Building Officials. This is one of the code bodies in the construction field. |
Live Load |
Occupancy load and other loads stipulated by use. |
Loads |
Also called boosters. The actual powder used to propel the piston down the barrel. There are different calibers (diameters) of loads as well as power levels. |
Muzzle Bushing |
The part of the powder tool where the fastener is inserted. |
Ogive |
The tapered point of a powder actuated fastener. |
Semi-automatic |
Refers to another type of tool which can either load the pin or the load automatically and NOT one at a time. |
Shank |
The long narrow portion of a powder actuated pin |
Shear Load |
When a load is applied perpendicular to the axis of the fastener |
Sill Plate |
Usually refers to a 2 x 4 or 2 x 6 lumber placed on the exterior wall. |
Single Shot Tool |
Refers to the type of tool that the operator puts in one pin and one load at a time. |
Spacing |
The distance from the center of a fastener to the center of the next closest one. |
Spall |
The area around the pin which concrete has been blown away. |
Spall Guard |
A rubber or metal shroud placed on the end of a powder actuated tool. Normally used when firing directly into the base material. |
Static Load |
Loads applied in a constant, continuous way. |
Tension Load |
When a load is applied along the axis of the fastener (commonly referred to as "pullout"). |
Tool Capacity |
This can refer to one of two things.
- The length of pin the tool can handle safety.
- The power level of the load the tool can handle safely
|
Ultimate Load |
The load at which the anchor will fail. |
