@PJ- Apologies, but we do not typically resell Hilti items and are unfamiliar with their installation recommendations. Well provide information about these confusions and considerations regarding roof anchors and roof anchor testing requirements below. 18.14Members not designated as part of the seismicforce-resisting system. The ASME B18.2.6 standard defines tolerances for both the body length and the grip length, but not for the thread length. Lets begin with defining what a fall protection anchor point is before we go into fall protection anchor point requirements. In lieu of the detection specimen requirements in Subparagraph 1.1(e)(1), a minimum of 55 percent of the flaws must be cracks. Even if a pull test to 5,000 pounds is done, the anchor may be damaged during the testing process and therefore needs to be removed and replaced. A centre tower, with an overall height of 55 metres, supports the superstructure above the pile cap level by means of four planes of cable stay in a semi-harp arrangement. Our company has been looking for working a solution to a loading dock problem. 18.14Design of anchorage zones for monostrand or single 5/8 in. Dave was great to work with and provide immediate answers to any questions that I had. Main function of anchorage is to transfer the stressing force to the concrete once the stressing process is completed. 8165 Graphic Dr. When post-tensioned, these cables applied a compressive force to the beam. The ventilation system must be designed to ensure that outside air is distributed to all bedrooms and main living areas. Over four years from 2009 to 2013, the daily vehicle count has dropped by over 16%. Related OSHA Content on Specific Compliance Standards: There are 2-headers on this page.

If you are using a proprietary post installed anchor, you would need to refer to that manufacturers recommendations. Components of a roof anchor must have a design strength that equals or exceeds the required strength. Your email address will not be published. The thread length is controlled by the grip gaging length, and the body length. The length of a mechanical rock anchor can be shorter than a cement grout or resin bond system since the load is being transferred by a mechanical head assembly rather than a grout or resin bond length. These included the highly variable geotechnical conditions due to the underlying marine geology of the seabed. (See this post to learn the difference between active vs passive fall protection.) When you partner with GTI, you partner with the industrys most progressive and proven manufacturer that has knowledge and experience from all parts of the concrete construction industry world-wide.

We had a few issues with the brackets but EFP had no issue in getting them switched out for us. The communication with our sales rep was great from start to finish. As the body length varies, and the grip varies, the thread length will vary. Notice a fall protection anchor must be able to support a load of 5,000 pounds. Williams Form Engineering Corp. We work with you to learn the project and select a solution to fit unique project specifications. When using the rock cone method, a conservative approach would be to assume the pullout cone starts at the top of the bond zone. Lets first clarify how OSHA defines a qualified person compared to a competent person. At both ends, the toll collection options include: The bridge has a reliable and redundant power supply, backed up by diesel generators and auto mains failure panels for critical loads, such as monitoring, surveillance, emergency equipment and communication services including aviation and obstruction indicators.
