▎ 摘　　要

NOVELTY - The component has a wall base layer comprising a reinforcing steel bar component and cement base material. The reinforcing steel bar component is located in an inner side surface of an insulating layer. The cement base material is cast and covered on the reinforcing steel bar component. A combined reinforcing layer is formed between the insulating layer and the wall base layer. The combined reinforcing layer comprises hydrated calcium silicate crystal formed by hydration reaction between active silicon dioxide material on an inner side of the insulating layer and calcium hydroxide on an outer side of the cement base material through cast-in-place process and later curing process. An end of a connecting piece is matched with a reinforcing net element. Another end of the connecting piece is connected with the wall base layer. The insulating layer is made of A-level fireproof insulating material. USE - Assembled building light heat preservation wallboard prefabricated component. ADVANTAGE - The component can use the hydrated calcium silicate crystal to effectively enhance connection strength of the insulating layer and the wall base layer in the later curing process when calcium hydroxide substance in the cement base material of the wall base layer are contact and hydrated to generate hydrated silicon dioxide crystal so as to increase tensile strength and improve anti-falling effect. The component can reduce weight of a light heat preservation wallboard, enhance heat preservation performance of composite heat preservation material, increase strength and rigidity of a heat preservation layer and reduce construction cost of a building. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an assembled building light heat preservation wallboard prefabricated component.
