195 INSTALLATION SPECIFICATIONS INSTALLATION PROCEDURES The installation requirements listed in the following tables are based on the minimum embedment depth. Adhesive mortar volume per inch is THREADED ROD OR REINFORCING BAR MUST HAVE A CHISEL POINT Drill a hole to the size and embedment based on the use of carbide tipped masonry bits which meet ANSI @@@@ ;;;; yyyy required. The tolerances of the drill bit used Standard B212.15 tolerances. should meet the requirements of ANSI B212.15. The combination of capsules to use for various embedment depths is listed in the load capacity sections which follow. To calculate the volume of adhesive @@@@ ;;;; yyyy mortar required for an embedment depth not listed, multiply the mortar volume per inch from the following tables by the embedment required. Select a combination of capsules using the capsule mortar volume in cubic inches. When Starting from the bottom or back of the anchor hole, blow clean with compressed selecting a combination of capsules, use sizes closest to the diameter of the rod air, brush the hole with a nylon brush, and blow it clean again. Anchor holes may to be used. For example, an installation using 5" threaded anchor rod at an be dry or damp, but should be free of standing water or frost. If using reinforcing 8" embedment requires 1.47 (8 x.184) cubic inches of adhesive mortar. A bar, be sure the bar will fit into the drilled hole. If a larger hole is required, the combination of a 5" capsule (.95 cu. in.) and a capsule (.55 cu. in.) diameter should be as close as possible to the diameter of the reinforcing bar. Prior yields 1.5 cubic inches of adhesive mortar. to installing check the capsule to be sure it is not damaged and invert several times at 6 F or above to confirm all of the resin is in SPECIFICATIONS FOR THREADED ROD a liquid state.

196 PERFORMANCE DATA ULTIMATE LOAD CAPACITIES - THREADED ROD IN CONCRETE The following capacities are the ultimate or failure load for the Chem-Stud adhesive when tested with high strength anchor rod in several compressive strengths of concrete. The capacity of the anchor rod should be taken into account in the design of any anchorage. The combinations of capsules shown are required to ensure that the proper bond area is achieved for each of the embedments listed. Do not attempt to use more than two capsules as the drill equipment used for installation may not have enough torque to properly spin the rod into the capsule. For installations where the combined length of capsules exceeds the length of the anchor hole, crush the first capsule using the anchor rod, then insert the second capsule. The larger capsule should be inserted into the anchor hole first. ANCHOR DRILL EMBED. MAX.

The combinations of capsules shown are required to ensure that the proper bond area is achieved for each of the embedments listed. Do not attempt to use more than two capsules as the drill equipment used for installation may not have enough torque to properly spin the rod into the capsule. For installations where the combined length of capsules exceeds the length of the anchor hole, crush the first capsule using the anchor rod, then insert the second capsule.

2 DESIGN CRITERIA BASE MATERIAL THICKNESS The minimum recommended thickness of solid concrete or masonry base material, BMT, when using an adhesive anchor is 125% of the embedment to be used. For example, when installing an anchor to a depth of 4", the base material should be at least 5" thick. Conversely, the maximum embedment should be 8% of the base material thickness. If a concrete slab is 1" thick, an 8" depth would be the maximum recommended anchor embedment. This does not apply to products designed for installation in hollow base materials. S S E D = Anchor Size S = Spacing E = Edge Distance BMT = Base Material Thickness COMBINED LOADING For anchors loaded in both shear and tension, the combination of loads should be proportioned as follows based on the Uniform Building Code: T 5 /3 () S VS T A () V A Where: Ts = Applied Service Tension Load TA = Allowable Tension Load Vs = Applied Service Shear Load VA = Allowable Shear Load Dependent upon the election to conduct certain optional independent test procedures, many ICBO evaluated products are currently analyzed more conservatively with the following proportion. T () S VS T A () V A TS TA 1..9.8.7.6.5.4.3.2.1 5 /3 + 1 + 1 TS VS () () TA VA + 1 (straight line).1.2 3.4.5.6.7.8.9 1. VS VA E 5 /3 TS VS () () TA VA D 5 /3 S + 1 (parabolic) BMT S ADHESIVE ANCHOR SPACING AND EDGE DISTANCE Adhesive type anchors can be installed closer to the edge of a concrete slab than mechanical anchors with no cracking of the base material. The published ultimate and allowable working loads are based on testing conducted at the spacing and edge distance required to obtain maximum load and should be reduced to account for decreased spacing and edge distance. The reduction load factors listed are cumulative. For example, the allowable working load for an anchor which is installed at a spacing and an edge distance less than that required for maximum load capacity would be multiplied by the appropriate factor from both the spacing and edge distance tables. The factors are normally applied to the allowable working load of the adhesive resin and then compared to the allowable strengths of the steel anchor rods used. See the Design Example featured earlier in this manual. SPACING BETWEEN ADHESIVE ANCHORS The following table lists the load reduction factor, Rs, for each anchor diameter, D, based on the center to center anchor spacing. To obtain the maximum working load in tension or shear, a spacing of 8 anchor diameters (8D) or greater should be used. The minimum recommended anchor spacing is 4 anchor diameters (4D) at which point the allowable working load for the adhesive resin should be reduced by 3%. Anchor spacing closer or less than 4 diameters (4D) need to be field tested. Actual base material conditions will determine any applicable reduction factor.

To obtain the maximum tension load, an edge distance of 6 anchor diameters (6D) and greater should be used. The minimum recommended edge distance is 4 anchor diameters (4D) at which point the allowable working load for the adhesive resin should be reduced by 4%. Edge distances closer or less than 4 diameters (4D) need to be field tested. Actual base material conditions will determine any applicable reduction factor.

R e 1 1 1 7 " 5 " Chem-Stud Anchor capsules can be used to install threaded anchor rod or reinforcing bars in submerged applications under water provided some installation and design criteria are followed. The anchor holes should be prepared following the standard installation procedures with the following exceptions. Special care should be taken to clean the anchor hole as a slurry of concrete paste tends to form on the walls of the anchor hole when drilling under water. Insert the proper size capsule into the anchor hole. Be sure the capsule is fully inserted to the bottom of the hole. Follow the standard installation instructions for spinning the anchor rod used into the capsule with an appropriate tool for submerged use. The setting time of the Chem-Stud adhesive in submerged applications depends upon the base material temperature as shown previously. Laboratory tests and field experience have shown that a decrease of 15 to 2% in the ultimate tension load capacity can be expected for an adhesive anchor which is installed under water. The design professional should include this reduction in his calculations. If the tension capacities are critical, a job site test is recommended. www.powers.com
