Figure 1

one anchor bolt cage is often con↑©sist of anchor bolts, upper ring←™, lower ring, splice plates, n←φ uts, washers, PVC sleeves, protecti₩‍ φve caps, heat-shrink tubes, support s €§≠tand bolt assemblies, e÷ λ‌tc. (See Figure 1). Accordi‍♥σ ng to different drawings±☆∏ and technical requirements, the≥λλ≠re will be different quantitieπσ"★s, dimensions, propertiesα≈→, payment terms, shipment, e™♠βtc. In some cases, the upp✘☆er ring, (which is also called alig <nment ring) will be removed after♣ ∏ the lower ring (which is al↕₩$so called embedment ring) and anchor b♦≠€olts were installed ≈®α↑and grouted. Then the tλ↑ower bottom T Flange will be fastened ‌★Ωwith those anchor bolts. Although∑ε• the install methods are differen©✔‌✘t between full cage or no upper ring c> age, but the products are the φ★φ♠same.

Our anchor bolt products hav•<✘↕e super high yield strength(up to 1100×β δ MPa) and tensile strength(uγ→p tp 1220 MPa). Regarding impact enφδπ₩ergy, our grade 8.8 anchor bolt eve £¶rages 60J , grade 10.9 eve® rages 35J which means our products→®ε× performance much higher than stand♥€ ard requirements.

5. Nut and washer

According to customers' differe‍≥≠σnt requirements, there are some differα↔‌£ent types of nuts in this  ÷±®system. But washers are only¥πγ placed at bottom of low✔≈er ring, and upper of T-Flange↓Ω (see Figure 5), in order to fast→$<​en the bolt and ring¶∏♦✘. In figure 5, nut and wa≥λαshers are dacromet coated. HDG also" ±☆ provided.
