The double wall structure of the composite strip situ

The present invention relates to an in-wall structure, especially the inner layer composite article using keel plate for a wall structure assembly. Comprising a keel assembly, and a panel assembly mounted on both sides of the keel; injection lightweight cellular concrete forming the inner partition wall between said panel; said keel assembly includes a keel and a plurality of webs, and the keel is located the panel is fixed to the side, and the connecting web and forming a gap between the keel through. Due to the use of the keel components, greatly improving the stability within the wall structure. There is a gap between the keel is formed, so that a space is formed between the side plates communication, only to open a hole grouting concrete is injected between the panels, easy construction, can effectively shorten the construction period.
