Resumen de Principles of the design of post-fixed anchors
Post-fixed anchors have been used in one form or another for over 100 years. They are typically needed in refurbishments, or in new-build projects where cast-in fixings are not practical or a late change has occurred.
Designing a post-fixed anchor can be a convoluted process, principally due to the number of variables involved when considering its use in any given situation. The anchor itself could be resin-based or mechanical, with this choice guided by the material it is to be fixed into and the required loads.
Technical Guidance Note Level 1, No. 29 Post-fix anchors provides an introduction to these fixings, and readers of this note should ensure they are familiar with the concepts discussed.
