Rule: When drilling holes for anchors to be used in concrete, brick or block- a hammer drill should be used. and edge distance guidelines, please refer to the Technical Guide, or contact Hilti. Add to enquiry basket . The lead thread does all of the cutting and will become ineffective after reaching 1-3/4" embedment. A self-tapping screw is a screw that taps its own threads when scr The information presented in this table is to be used in conjunction with the design criteria of ACI 318-14 and ACI 318-11. ���6@��a&F�>���4����� Uq This is also known as a "blowout" of the base material. 0 This pressure goes out and up the length of the anchor forming what is commonly called a cone of concrete, as it is cone-shaped in appearance. Anchor bolt edge distance 1.75 inches or 2.75 inches, dependent upon sill plate Testing protocol monotonic versus pseudo-cyclic Wood-concrete interface condition friction versus “frictionless” membrane To properly generate test data for the purpose of assessing behavior, a new displacement based loading protocol was developed. The minimum embedment depth is different for each anchor and each diameter. �ht�`������]�S;L ��`�x/�ِ��@�϶�zu�`�#X��0��ޣ�C�e�U��vH� }�e�#,��$�E�'��=�d{y���՛�? Edge distance is distance from centerline of anchor to the free edge of base material in which the anchor is installed. endstream endobj startxref If tension is applied to the anchor, ca1 is the minimum edge distance. Shear Loads towards a free edge for all embedment depths are for single anchors where Spacing ≥ 3 x Edge Distance Epoxy Resin Page 2 of 6 Version 4 Grade 8.8 Zinc Plated Studs Performance Data (C20/25 Uncracked Concrete) Thread Diam Characteristic Resistance Design Resistance Approved Resistance Design Spacing Design Edge Distance mm kN kN kN mm mm Tensile Shear Tensile Shear Tensile … 2) See ICC-ES ESR-1970 for replacement parts. z�I� �,+J��S�p��L��5��ͦծ^��}��������AP�Y]��o���Ŝ}�V��O/�����Z�ل�ׂ�g>~�d��'��~�����}K�5���P�w���y[�5_T��y��޾��E�n���Y��[��޵�I����3U~��nwL�|�n�����������78{^�7��&ۦZ����}�q|y��y�����D_:�Z~�V�f1Y߮j&�����`�w���ضyh7[�g���w�K��w��f٬o��f=Y�4>o��vvWm���������߫��0�Ͽ��BW�1�O��l�v���3Q8�P&d���Kf�c��L��E��[ƤG:�!�6�\ Effective embedment depth is the overall depth through which the anchor transfers force to or from the surrounding concrete. OTHER (D.2 – D.4) Loads with high fatigue or impact not covered (D.2.4) By Appendix D. Anchors and anchor groups can be designed … This .

Please remember that these are just "rule of thumb". document.getElementById("copyright_year").innerHTML = new Date().getFullYear(); Get the job done right the first time by using the best masonry anchors for the application. Chemical fixings are the fixing solution for transferring extreme loads in concrete, aerated concrete or masonry expansion-free. Login to see prices. Chemical anchors (I prefer the simpler term ‘resin anchors’) exert no setting stresses in the base material so can be specified at closer edge and spacing distances in concrete and will usually develop the strongest anchorage in masonry materials – which are their main ‘Pros’. G5 Adhesive Edge/Spacing Distance Load Factor Summary for Installation of Threaded Rod and Reinforcing Bar 1, 2 LOAD FACTOR DISTANCE FROM EDGE OF CONCRETE Critical Edge Distance—Tension 100% Tension Load 1.25 x Anchor Embedment Minimum Edge Distance—Tension 70% Tension Load 0.50 x Anchor Embedment Critical Edge Distance—Shear
