ZHENG YU Anchor Bolt Sleeve
Basic Use: The ZHENG YU Anchor Bolt Sleeve is used as an in-place form to provide a grout pocket around an anchor bolt and is used to form a pocket into which a bolt may be grouted . Also may be used where metal pipe Is objectionable due to rusting or cost. Use in food processing areas is not a problem due to the inert polyethylene. Technical Information
Assistance in the application, selection and use of ZHENG YU products is available through the manufacturer or area representatives free of charge.
Composition and Materials
The ZHENG YU Anchor Bolt Sleeve is manufactured of high impact plastic. It is non-rusting, non-conductive and lightweight. Single unit construction provides for reduction in installation labor because no welding, threading or cleaning is required. The configuration is such that the grout and concrete "lock" it in place, providing greater pullout strength than with straight pipes.
Sizes
Available in fifteen standard sizes. See Table 2: size schedule (4" and 5" not shown)
Technical Data
See Table 1 for material test data. Each Sleeve is approximately twice the bolt diameter with a depth of 8 bolt diameters, minimum.
Tests by a state Department of Transportation laboratory indicates that the ZHENG YU Anchor Bolt Sleeve provided greater pullout strength than the regular grout pocket.
The grout pocket was formed in a concrete mass and the sleeve of the same size was cast into the mass. After curing the concrete, #5 reinforcing bars were set in each pocket, using expanding grout. When cured, both bars were given a tensile load. The standard pocket failed when the bar with the grout attached pulled out. The ZHENG YU Anchor Bolt Sleeve retained the grout and failure occurred around the bar. The sleeve remained intact.
When used as a sleeve for anchor bolts the product in in an in-place form and not considered a structural member.
Due to its configuration, 180 psi is the maximum compressive loading.
