To realize the secured assembly of assembled wallboard and main body frame.
(3) frame beam column corrosion of steel is reduced, structure fire performance is improved.Steel frame beam column is encased outside outer page concrete,
So that steel frame beam column is isolated from the outside, reduces corrosion of steel, meanwhile, concrete has good flameproof effect, can make up steel
The disadvantage of frame structure fire resistance property difference.
(4) good integrity, structural thermal insulation integration.Page concrete is wall together with foamed concrete frame inside and outside wallboard
Plate forms the higher foamed concrete shell of intensity, to mitigate weakening of the middle part built-in heat insulation layer to wallboard strength, improves component
Intensity.Built-in heat insulation is placed in the middle part of concrete structural slab, so that inflammable thermal insulation material is isolated from the outside, insulated fire effect
It is good.
(5) the utility model wallboard is prefabricated in the big modularized production of factory, and production is simple, is easy to realize on assembly line high
Efficiency industrialization production.Meanwhile big modularization wallboard, convenient for the installation of construction site assembled, installation node is few and firm, construction
Simply, worker's operation intensity is significantly reduced, the engineering amount of labour used is reduced, while efficiently shortening the engineering site construction time, is suitable for
Wide popularization and application in practical projects.
