The use of reinforced frame floor bearing plate not only improves the construction quality of floor slab, but also speeds up the construction progress. What should we pay attention to when using reinforced lattice floor bearing plate? Let's listen to the introduction of the manufacturer of reinforced lattice floor bearing plate.
1、 The strength grade of floor concrete is C20; Zui large applicable spans are those without temporary support during the construction stage of reinforcement grid formwork; slab continuity refers to two equal spans
2、 Material: HRB400 and hpb300 reinforcement should be used for the upper and lower chords, and hrba4o or cold rolled reinforcement with performance equal to crb550 should be used for the web member; Hpb300 and hrb40o should be used for the horizontal and vertical reinforcement of the support, Q235 cold rolled steel plate or galvanized steel plate of no less than s250gd + Z grade should be used for the bottom plate, and the galvanizing amount of galvanized steel plate on both sides should not be less than 120g / m2.
3、 The deflection control value in the construction stage is 10 / 180 and 20mm, which is smaller. When there are more strict requirements for the deflection value, it needs to be designed separately.
