▎ 摘　　要

NOVELTY - The interior wall has a front inner wall panel case mechanism (1), a foamed interlayer (2) and an inverted inner wall panel case mechanism (3). The foaming interlayer is arranged between a front inner wall panel case mechanism and the anti-inner wall panel case mechanism. The inverted inner wall panel case is composed of an inverted inner wall panel, an inner groove and a first side butt joint. The front inner wall panel case mechanism includes a front inner wall panel, a second side butting portion , an inner through groove, an inner push partition (14) and a rotating shaft. The front inner wall panel is provided with the rotating shaft. The rotating shaft is located at back of the inner through groove and right side groove wall of the inner through groove that is flush with an outer wall of the rotating shaft. A size of the inner through groove matches a size of the foamed interlayer. USE - Foamed interior wall used for building. ADVANTAGE - The setting of the rotating shaft plays a role in alleviating the corners of the foamed interlayer, thus preventing wrinkles and cracks at the bends of the foamed interlayer. The structure is simple, and the replacement of the foam interlayer is convenient. The foam interlayer is made of graphene and lipid composite foam material, which makes lighter in weight and higher strength, and the inner wall product quality is better. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing foamed interlayer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of the splicing of the high-strength lightweight foamed interior wall for building.
