Muscle and junction steel plate brush corrosion resistant coating, sprays fireproof coating.
Beneficial effects of the present invention：Technical scheme simple structure, practical, safety, horizontal external prestressing pressure
Shape steel plate composite floor is a kind of New Floor Slab, applies prestressing force to profiled steel sheet combination floor using transverse tensioning method, changes traditional
It is that, along the transverse stretching perpendicular to presstressed reinforcing steel, required horizontal tension is only the 17～15 of longitudinal tension force along presstressed reinforcing steel longitudinal direction tensioning
Equal prestressing force effect is can reach.In addition, applying prestressing force using transverse tensioning method, loss of prestress is reduced, tensioning is improve
The degree of safety of efficiency and tension operation, is suitably applied assembled architecture, is particularly suited for structural strengthening.Compoboard is carried out adding
Gu, no condition carries out longitudinal tensioning in many cases, using the method, little to component damage, and consolidation effect is good.Build at present
This kind of floor is there is no in technical field.The technical program has tensioning efficiency high, tension operation safety, short construction period, deadweight
Gently, it is capable of a kind of prestressing force profiled steel sheet combination floor of enhancing structure shock resistance.Conventional floors stress performance can be improved, especially
Which is applied to assembled architecture and profiled steel sheet combination floor is reinforced, and meets actual demands of engineering.
