35 <br /> moving the vertical reinforcing bars up and down will consolidate the concrete. When such <br /> rodding is done,care should be taken not to hit the webs of the Wallforms. Using a vibrator <br /> (`stinger)is useful to add an extra measure of insurance that the voids have been filled. One <br /> suggested method is to touch the stinger to the top of each protruding rebar to vibrate the entire <br /> rod thus transferring vibration to the concrete. <br /> 8.7 Test Holes <br /> Drill test holes in areas that the poured concrete may have more difficulty reaching. <br /> Use a 2"dia. hole saw. Observe that concrete comes through the test holes during the pour. <br /> Areas of concern are: <br /> --Either side of openings that may have additional rebar. <br /> --under openings. <br /> NOTE: Although the concrete will mechanically set overnight and secure the positions of braced <br /> window and door openings,the bracing assemblies should not be disturbed for at least 12 days. <br /> j In order to realize the true design strength of the wall assembly, ultimate loading should be <br /> �/ avoided for at least 28 days. Additional Wallforms may be stacked the next day. All subsequent <br /> lifts and special structures such as lintels should be accomplished using the same techniques and <br /> conditions as described above. <br /> 9.0 Trusses <br /> Determine the necessary layout pattern for the anchoring devices,insure that they are centered in <br /> the wallform cores.Anchor bolts or steel plates for the attachment of the roof structure must be <br /> deeply imbedded into the concrete fill while the mix is still workable(not more than 30 minutes <br /> after placing the concrete). Refer to the details in the plans for the building provided by the <br /> design/engineering team. <br /> 10.0 Fastening to the Wallforms. <br /> Mechanical fasteners appropriate for the weight of the item to be attached should be anchored <br /> directly into the concrete core. For lighter loads coated#8 or#9 deck screws can be used if the <br /> depth of penetration into the wallform is maximized. Fastening screws at points where the <br /> fetie <br /> ShelterWorks General Application and Technical Information(GATI)version 2.5 <br />
