The hanger rods are installed in a crossed mode, the crossed part is divided into a lower hanger rod 10 and an upper hanger rod 20, the lower hanger rod 10 and the upper hanger rod 20 are connected through a cross sleeve 30, the lower end portion of the lower hanger rod 10 is bent to form a lower broken line section 12 used for being connected with a suspended ceiling keel system, and a lower straight line section 11 of the lower hanger rod 10 is connected with the cross sleeve 30. The upper end of the upper hanger bar 20 is bent to form an upper break line segment 22 for securing to the structural member 50 by the securing assembly 40, and the upper straight segment 21 of the upper hanger bar 20 is connected to the cross sleeve 30.
The hanger rod and the cross sleeve 30 form a triangular stressed truss system suspended ceiling reverse support, the truss system only has axial force and does not have bending moment and shearing force, the bending resistance and rigidity of the reverse support structure are enhanced, and compared with the reverse support structures such as a profile steel hanger rod and a steel structure conversion layer, the reverse support structure saves steel, reduces cost and improves construction efficiency.
In one embodiment, the suspender is a galvanized full-thread screw rod, the zinc coating has mechanical protection effect and electrochemical protection effect on the iron substrate, the suspender is protected from corrosion, the full-thread screw rod is convenient to process and use, and the suspender can be cut to any length on site for use.
The undersize of the diameter of the hanging rod can reduce the stability and rigidity of the suspended ceiling anti-support structure, and the oversize diameter of the hanging rod can increase the cost of the suspended ceiling anti-support structure. In order to take account of the stability and cost of the anti-support structure of the suspended ceiling, in one embodiment, the diameter of the suspension rod is 8-16 mm, the diameter of the suspension rod may be 8mm, 10mm, 12mm, 14mm, or 16mm, and the diameter of the suspension rod may be any value between any two values, and of course, in other embodiments, the diameter of the suspension rod may be smaller than 8mm or larger than 16 mm.
The lower broken line segment 12 is used for being connected with a suspended ceiling keel system, enough space is reserved for suspended ceiling leveling by the lower broken line segment 12, the upper broken line segment 22 is used for being fixed on a structural member 50 through a fixing assembly 40, the upper broken line segment 22 meets the requirement of being connected with the fixing assembly 40, in one embodiment, the lengths of the lower broken line segment 12 and the upper broken line segment 22 are 40-60 mm, the lengths of the lower broken line segment 12 and the upper broken line segment 22 can be 40mm, 45mm, 50mm, 55mm or 60mm, and the like, the lengths of the lower broken line segment 12 and the upper broken line segment 22 can be any value between any two values, and of course, in other embodiments, the lengths of the lower broken line segment 12 and the upper broken line segment 22 can also be smaller than 40mm or larger than 60 mm.
