A wedge anchor will only hold as well as the strength of the concrete into which it is installed. The wedge anchor, drop-in anchor and concrete strike anchor can only be used in solid concrete and have the highest & most consistent holding values in concrete. RE: Epoxy Vs. Wedge Anchors? To determine the force at the grout-to-bolt interface, use the following calculation: F = BD x x L x 1600 psi Where: F = Bolt Pullout Force in lbs. 5.4 The measured pullout strength is indicative of the strength of concrete within the region represented by the conic frustum defined by the insert head and bearing ring. Anchor Diameter Embedment Depth Concrete Compressive Strength 3,000 psi 5/16” 1-3/4” 3,045 lbs. 0000008012 00000 n 0000071376 00000 n Table 1, the pullout strength in tension need not be evaluated. Seismic Wedge Type Anchors— Trubolt+ Wedge anchors consist of a high-strength threaded stud body, expansion clip, nut and washer. Consider your four KWIK BOLT® wedge anchor options—progressive levels of performance geared to various base materials—seismic, cracked or uncracked concrete, grouted masonry and lightweight concrete over metal deck. vatec Revo screw (Fig 4) failed by eyelet cutout in the vast majority (80%) of tests. Pullout strength does not control design of indicated anchors. A 1/8 toggle can hold 30 pounds on 1/2-inch drywall and a 3/8-inch toggle can handle a hefty 50 pounds or more safely. 0000008961 00000 n 9. Sloan Abstract: During the last 30 years various researchers have proposed approximate techniques to estimate the uplift ca- pacity of soil anchors. Effective Embedment Depth (in.) concrete strength determination by pull-out tests on wedge-anchor bolts. Higher loads to failure were found in regions in the proximal part of the tuberosities. d%e$3��/(�lށl��RhxQ4�1��DVg �e`($� �b�P�x�i5c;�*�&.��'����3�1�1|`�`*b:�l�\Ƭ���,��Ǵ�i�z�P�����\v���1L�L�E�Q�Ѷm��c� Ks�D5�3����6� �3#�5�.� when the nominal anchor strength is controlled by anchor bolt yielding, Φ is taken equal to 0.90, when the nominal amchor strength is controlled by anchor pullout, Φ is taken equal to 0.65. 4.1.5 Requirements for Static Steel Strength in shear, Vsa: The nominal steel strength in shear, Vsa, of a single anchor in accordance with ACI 318-14 Section 17.5.1.2 or ACI 318 (-11, -08, -05) Appendix D Section D.6.1.2, as applicable, is given in Table 1 of this report, and must be 0000015336 00000 n Anchor pull-out strength by position of insertion and direction of pull Anchor 1 cm 3 cm Parallel Perpendicular Parallel Perpendicular Mitek GI 74.4 57.5 84,3 43.4 Mitek GII 80.9 82.5 92,1 Statak 74.7 84.5 102,1 103.2 Acufex rod 104.8 63.6 118.2 77.1 Acufex wedge 96.0 58.2 99.0 89.8 Values are mean failure loads (N) for anchors at 1 and 3 cm from the joint surface.

Not fully expanding a drop-in anchor because the wrong setting tool was Determine steel and concrete capacity only. There was no real variation of failure strength by test location. Wedge Anchors. 0000008694 00000 n Environmental exposures include freezing and thawing, moisture, decreased and elevated temperatures and corrosion. The pullout strength calculation is different for headed and hooked anchor bolts. pullout strength of anchors is highly dependent on the base material’s concrete strength, all anchor tests used for the final analysis will be installed in concrete from the same batch.

I prefer epoxy, ran into too many oversized holes when workingwith wedge anchors. Thus the anchor can be successfully installed in a hole as shallow as 1-5/8”, appreciably less than the recommended 2-1/4” minimum embedment. This is for air diffuser supports (low pullout forces) within a waste water channel (12 ft deep). 0000006525 00000 n But, when so installed, the pullout strength for.

Wedge anchors and sleeve anchors (Red Heads) should not be used on green concrete, and I think That's what we are talking about here, a newly poured slab with a perimeter curb. Nominal Anchor Diameter (in.) With extreme load, anchor spacing and edge distance capabilities, KWIK BOLT® TZ and KWIK BOLT® 3 wedge anchors satisfy the toughest code requirements—along with your demands for productivity. The mechanical fixation (henceforth, pullout strength) of the suture anchor is known to be affected by its design, such as the pitch and number of threads, length, size, and overall shape. These engineering calculators for the design and strength charateristics of concrete anchors are in accordance with ACI 318-02. 0000006321 00000 n Anchor bodies are made of plated carbon steel. H�\��j�0E�� 0000003833 00000 n Concrete sleeve anchors can be used in concrete, brick or block but their holding values are less in terms of shear and pullout values. When applying any kind of drywall anchor, you should understand how they work and which screw anchor may work best to put into a hollow wall. 5 Anchor pullout strength does not control anchor design.
