Description

Technical Field

[0001] The utility model relates to the field of building partition wall structures, in particular to a fixed connection structure of a high sound insulation partition wall system. Background Art

[0002] Lightweight wall panels are the abbreviation of lightweight partition boards used in construction. They are made of lightweight materials or lightweight structures, and have mortise and tenon structures on both sides for easy splicing.

[0003] The existing sound insulation wall system (CN 114991346 A) includes a first panel, a first keel, a center panel, a second keel and a decorative panel arranged in sequence along the thickness direction of the wall. The first keel and the second keel are composed of a rectangular frame and a number of horizontal bars and a number of vertical bars located in the inner area of ​​the rectangular frame and fixedly connected to the rectangular frame. The horizontal bars and the vertical bars are cross-distributed. The rectangular frame, the horizontal bars and the vertical bars of each keel are filled with sound insulation cotton in the gaps between them; the center panel is a large wall panel composed of several small lightweight wall panels spliced ​​together by a tenon and mortise structure. Since the vertical bars of the keel of the existing patent mostly use U-shaped steel components with the opening facing the sound insulation cotton side, however, the mechanical strength and flexural strength of such vertical bars are both biased, and the shaking of the wall during an earthquake can easily squeeze the vertical bars and cause them to deform.
