Another object of the present invention is to provide the Sandwich insulation wallboard reinforced steel concrete damaged frames described in one kind
Method Sandwich insulation wallboard manufacturing method, the Sandwich insulation wallboard manufacturing method the following steps are included:
Step 1, binds first layer reinforcing steel bars of wallboards and edge constructs beam column reinforcing bar；
Step 2, installation side form pour first wallboard；
Step 3 is laid with polystyrene foam plate after first layer wallboard reaches 80% concrete crushing strength on it,
To ensure effectively to bond between cystosepiment and wallboard, a small amount of Self-leveling sand is used between polystyrene foam plate and first layer wallboard
It starches levelling；
Step 4 binds second layer wallboard distributing reinforcement, and the tension rib between two layers of wallboard is arranged；
Step 5 pours second layer wallboard.
The method and manufacturing method of Sandwich insulation wallboard reinforced steel concrete damaged frame provided by the invention, using folder
The energy dissipation capacity of frame can be enhanced in core heat-insulation wall plate reinforced steel concrete damaged frame, it is made to restore normally to use function
Can, and resist earthquake load.It can be realized among the sandwich wall board used simultaneously with heat preservation fireproofing material polystyrene foam plate
Building fire protection and wall reducing energy consumption.In addition, sandwich wall board can be prefabricated in the factory, in-site installation, speed of application is fast, construction quality
Height facilitates the quick reparation of damaged frame；In conclusion having been adapted to using the impaired frame of Sandwich insulation wallboard reinforcing damaged fast
The needs of speed, building energy conservation and wall innovation.
