Double-layer composite slat cast-in-situ internal parting wall structure

The invention relates to an internal parting wall structure, in particular to a double-layer composite slat cast-in-situ internal parting wall structure adopting a keel component. The structure comprises the keel component and panels mounted at two sides of the keel component; light foam concrete is poured between the panels to form the internal parting wall; the keel component comprises a pair of keels and multiple connection plates; the keels and the panels positioned at the corresponding sides are fixedly connected; gaps are formed between the keels connected by the connection plates. Due to the adoption of the keel component, the stability and firmness of the internal parting wall are greatly improved; the gaps are formed between the keels, so a communicated space is formed between the panels at two sides; only one grouting hole needs to be formed when the concrete is poured between the panels, the construction is convenient and the construction period can be effectively shortened.
