Double-layer light-steel-keel sound-insulating wall and construction method thereof

Abstract

Disclosed is a double-layer light-steel-keel sound-insulating wall. The double-layer light-steel-keel sound-insulating wall is characterized in that the wall comprises two layers of parallel light-steel keels, a middle-layer plate, sound-insulating materials and surface-layer plates, two side faces of the middle-layer plate are abutted against and fixedly connected with the inner sides of the two-layer light-steel keels, the surface-layer plates are fixed connected on the outer side of the light-steel keel at each layer, the sound-insulating materials are filled in the light-steel keels, each light-steel keel is provided with multiple vertically-arranged vertical keels, multiple rows of transverse keels are transversely connected among all adjacent vertical keels, longitudinal intervals of the transverse keels are 600-800mm, and transverse edges and longitudinal edges of the middle-layer plate and the surface-layer plates are connected with the transverse keels and the vertical keels respectively. The double-layer light-steel-keel sound-insulating wall is steady in structure, the height can reach 4.5-6m, the defect of easiness in deformation in the prior art is overcome, sound-insulating effect is good, and weight-counted sound insulation quantity reaches 55-60Db.

Description

Technical field [0001] The invention relates to a building partition wall, especially a double-layer light steel keel soundproof wall. Background technique [0002] Light steel keel sound insulation wall has the advantages of light weight, high strength and good sound insulation performance. It is widely used in indoor buildings such as offices, halls, and hotel rooms. It is a common type of partition wall in building partitions. At present, most light steel keel sound insulation walls are single-layer light steel keel sound-proof walls, consisting of a single-layer light-steel keel frame fixed on the upper base, lower base and both sides of the base, and sound insulation materials filled in the single-layer light-steel keel frame and fixed The single-layer light steel keel is composed of gypsum boards on both sides, but once the height of the single-layer light steel keel sound-insulating wall reaches 4.5m-6m, the light steel keel cannot meet the structural stability required by...

AI Technical Summary

Problems solved by technology

At present, most of the light steel keel sound insulation walls are single-layer light steel keel sound insulation walls. The gypsum boards on both sides of the single-layer light steel keel are composed of gypsum boards, but once the height of the single-layer light steel keel sound insulation wall reaches 4.5m-6m, the light steel keel cannot meet the structural stability required by the height, resulting in light steel keel The keel is deformed, it is difficult to apply to buildings with high-rise distances, and there are limitations

In order to deal with this defect, square steel is generally added to the light steel keel frame for reinforcement, resulting in more complex light steel keel frame structure, increased construction costs, cumbersome construction procedures, and prolonged construction period; the installation position of square steel depends entirely on the experience of construction personnel Judgment, the technical level of construction personnel is high, and it is difficult to popularize and apply
