Attached steelframe composition, wherein ribbed plate is building non-bearing external decorative member, and carrying on the back attached steelframe is the metal framework with structure function,
By flexible roof bolt and gravity anchor support GRC panel with ribbing, and it is connected with major structure of construction.
The general scale of GRC decorating outer wall of building hanging plate is larger, and up to 4500mm, each veneer is prefabricated in the factory to be added veneer height
Work, transport reach construction site, are installed in concrete or steel construction main body using pre-buried anchoring or rear anchorage style.GRC is hung
Seam between plate should generally have one fixed width, and design seam principal element in need of consideration includes: temperature and humidity variation bring
Harmomegathus effect, earthquake displacement effect, manufacture and construction error, wind load displacement effect, concrete preparation in shrinkage and creep
Effect.In addition, the waterproof performance for also needing that architectural construction is combined to guarantee metope in area of heavy rainfull.
To meet normal deformation and displacement request, it is generally the case that the joint gap of GRC component can refer to following equation meter
It calculates:
For splicing glue-line:
For open seam:
Wb=B+C (2)
In formula: Wb --- joint gap (mm)；
A --- GRC component is in 1 year because temperature and humidity changes issuable displacement (mm)；
The displacement capacity (%) of δ --- sealant；
B --- the foozle of GRC component can use 3mm；
C --- consider the pre- allowance (mm) that the other factors such as geological process influence, takes not less than 2mm.
