Lastly, the type of fastener required for the application must be determined. Will the fastener be placed in (a) the mortar joint, (b) the solid section of the block, or (c) the hollow section of the concrete block? Some applications may allow each fastener to be placed in the same part of the block while other installations require that each anchor be placed in different sections of the block. The 5/8" and 3/4" diameter machine screws are typically reserved for heavy duty use. They are availabe in a wide array of lengths in both 3/16" and 1/4" diameters.http://www.china-packmachine.com/product/others/vacuum-machine/
A concrete block, cement block, foundation block or concrete masonry unit (CMU), is a large rectangular block used primarily in the construction of walls. Lag shield anchors are available in short and long lengths. Different lengths are available in each diameter and can be used in applications with many embedment requirements. Heavy duty, non-vibratory, non-shock loads would require a through-bolted fastening technique or a concrete epoxy type fastener. These concrete anchors are now produced from a material called Zamac - a softer, non-corrosive metal. The hollow section of the block is the least desirable section of the block in which to fasten but sometimes can not be avoided.
This fastener is used in light duty applications since it is only available up to 5/16" in diameter. This anchor is very versatile because there is a wide range of lengths available allowing materials of many different thicknesses to Vacuum Machine be attached to a block wall. Fastening into the mortar joint can be an excellent option depending on the quality and quantity of the mortar used to set the block in place. Load type will also be a determining factor during the installation of concrete anchors. These fasteners may be used in light or medium load applications with a non vibratory, non-shock load. The extra length of the long lag shield increases its ability to perform properly. There are four options available that can be used in concrete block:
The next step in the process is to ascertain the type of load that is going to be anchored. The double expansion anchor should be used in applications with questionable base material quality.The single expansion anchor and double expansion anchor require the use of a machine threaded fastener with national coarse threading. Sleeve anchors with diameters of 5/8" and 3/4" are usually considered heavy duty anchors. The anchor chosen will depend on the type of bolt being inserted into the anchor as well as the quality of the base material. Example: Machine Screw Anchor, Lag Shield Anchor, Single Expansion Anchor, Double Expansion Anchor, Leadwood Screw Anchor
