basic provisions of insulation materials:
1. The sandwich exterior wall consists of an inner leaf wall, an insulating layer and an outer leaf decorative block wall. The inner and outer leaf walls are tied by tie pieces. Whether an air layer is set between the insulating layers can be determined according to the design.
The inner leaf wall is a structural load-bearing wall or filler wall, which generally refers to the cast-in-place reinforced concrete shear wall, frame filler wall, reinforced block wall and other materials.
2. The outer leaf wall generally uses 90mm thick decorative hollow concrete block (the outer leaf wall takes 90mm thick decorative block as an example, and other thickness outer leaf wall can also be used, but the thickness should not be less than 60mm), and connects the inner and outer leaf walls with tie pieces. The outer leaf wall together with the insulation layer is supported by the load-bearing inner leaf wall from each floor slab to pick out the pallet or joist to hold the outer leaf wall and the insulation layer.
Sandwich insulation wall to take layered support approach, one is to be safe and reliable, to maintain the stability of the external decorative block wall, to ensure that under the action of wind and earthquake does not fall; at the same time, but also to reduce the layers of joist or pallet load.
