Abstract
The invention relates to building materials, in particular to an assembly type staggered peak soundproof autoclaved lightweight concrete (ALC) board composite wall. The composite wall comprises two side main wall bodies and a connection keel. The main wall bodies at least comprise ALC boards. A gap and the connection keel are arranged between the two side main wall bodies. The size of the gap is larger than the width of the connection keel, and the wall body thicknesses of the two side main wall bodies are different. The composite wall is reasonable in structure arrangement, thus the ALC boards avoid direct contact, the sound wave on the sound source side cannot be transmitted to the other side directly through physical vibration, a 'sound bridge' does not exist, and the soundproof performance of the composite wall is improved. The composite wall do not have an obvious coincidence effect due to the used different-thickness ALC boards, so that the comprehensive soundproof performance of the composite wall in different frequency bands is improved.
