Use expansion bolts to fix the hanging rods. For suspended ceilings without access, if the length of suspender is less than 1000mm, φ 6 suspender can be used. If it is more than 1000mm, φ 8 suspender should be used, and reverse support should also be set. The suspender can use cold drawn steel bars and coiled steel bars, but the coiled steel bars shall be straightened mechanically. For the ceiling with access, if the length of suspender is equal to 1000mm, φ 8 suspender can be used. If it is greater than 1000mm, φ 10 suspender shall be used and reverse support shall be set. One end of the suspender is welded with the φ 30 × 30 × 3 corner code (the hole diameter of the corner code shall be determined according to the diameter of the suspender and the expansion bolt), and the other end can be tapped with a screw rod larger than 100mm, or it can be welded with a finished screw rod. The fabricated suspender shall be subject to rust prevention treatment. The fabricated suspender shall be fixed on the floor slab with expansion bolts and punched with an impact hammer. The hole diameter shall be slightly larger than the diameter of the expansion bolt.
