Description

Technical Field

[0001] This invention belongs to the field of internal soundproof wall technology, specifically, it relates to a nail-free internal soundproof wall and its installation method. Background Technology

[0002] Nail-free interior soundproofing walls are an innovative indoor sound insulation solution designed to avoid the damage and marks caused by using nails or screws on traditional walls. Nail-free interior soundproofing walls typically use lightweight materials such as specialty rock wool boards, glass wool boards, or other synthetic fiber materials. These materials not only provide excellent sound insulation but are also lightweight, easy to install, and easy to adjust. The wall's frame structure design needs to maximize sound insulation performance, typically using metal or synthetic materials to construct a robust frame to support the sound insulation material and optimize sound insulation effects. The core of nail-free interior soundproofing walls lies in eliminating the need for traditional nails or screws to fix the wall materials. Instead, these walls typically use adhesive, glue, or embedded structures for fixation, methods that minimize damage to the main structure (such as walls, floors, or ceilings). Many nail-free interior soundproofing walls feature a modular design, making installation and adjustment more flexible and convenient, and simplifying the maintenance and replacement of sound insulation materials. Soundproof walls utilize high-efficiency sound insulation materials, such as special rock wool boards or other high-density fiber materials. These materials effectively absorb and isolate sound waves, thereby improving the quality of the indoor acoustic environment. Sealing between the walls and the floor, ceiling, and surrounding structures is a crucial step in ensuring sound insulation; effective sealing techniques prevent sound from propagating through gaps around the walls.

[0003] Existing nail-free internal sound insulation walls have complex installation structures, low adjustability, and can only be adapted to walls with the same structure. Summary of the Invention

[0004] In view of this, the present invention provides a nail-free internal sound insulation wall and its installation method, which can solve the problems of the complex installation structure, low adjustability, and the fact that the existing nail-free internal sound insulation walls can only be adapted to walls with the same structure.

[0005] This invention is implemented as follows:

[0006] A first aspect of the present invention provides a nail-free internal soundproof wall, comprising a pre-assembled component, a top frame, a bottom support frame, a middle wall support frame, and a sound insulation component. The pre-assembled component is pre-installed at the top of the space where the internal soundproof wall is located, with its major axis direction being the same as the installation direction of the internal soundproof wall. The top frame is fixedly connected to the pre-assembled component, and the bottom support frame is provided at the bottom position corresponding to the top frame. The middle wall support frame is fixed between the top frame and the bottom support frame, and the middle wall support frame, the top frame, and the bottom support frame together form the frame structure of the internal soundproof wall. The sound insulation component is a vertical multi-unit structure, fixed on the middle wall support frame to form the internal soundproof wall.

[0007] The sound insulation components include multiple components, the sum of their lateral lengths installed on the central wall support frame being the same as the width of the space where the inner sound insulation wall is located, and their length being the distance between the top keel frame and the bottom support frame; the sound insulation components are fixed on both sides of the central wall support frame to improve the stability and sound absorption effect of the inner sound insulation wall; the sound insulation components include sound-absorbing panels and sealing elements, the sealing elements covering the edges of the sound-absorbing panels, the sound-absorbing panels including a support layer, an inner sound-absorbing panel, a moisture-absorbing panel, and an outer sound-absorbing panel, the inner sound-absorbing panel, the moisture-absorbing panel, and the outer sound-absorbing panel being staggered and fixedly connected to reduce the reduction in sound absorption effect caused by gaps.

[0008] The technical effects of the nail-free internal soundproof wall provided by this invention are as follows: Skeleton structure: The top keel frame, the bottom support frame and the middle wall support frame together form the skeleton structure of the internal soundproof wall, providing stable support.
