A composite sound insulation mechanism of a residential building imitating a car shock absorption structure

Abstract

This utility model relates to the field of residential building sound insulation technology, specifically a composite sound insulation mechanism for residential buildings that mimics the vibration damping structure of a car. It includes a composite sound insulation layer and multiple sets of support components installed inside the composite sound insulation layer. The composite sound insulation layer, from top to bottom, consists of a metal support plate, a centrifugal glass wool layer, a honeycomb panel, a non-woven fabric layer, and a nitrile rubber pad layer. This composite sound insulation mechanism for residential buildings, mimicking the vibration damping structure of a car, effectively blocks airborne sound through the synergistic effect of the structures within the composite sound insulation layer. Simultaneously, the multi-level buffer structure of the support components cancels out structural sound transmission, solving the problem that traditional structures only block airborne sound but not structural sound. Furthermore, the three-level vibration damping structure formed by the first, third, and second springs absorbs a certain amount of vibration energy, significantly reducing structural sound transmission. The gap fit between the sleeve block and the top column, and the elastic connection of the second spring, prevent components from loosening due to vibration.

Description

Technical Field

[0001] This utility model relates to the field of residential building sound insulation technology, specifically a composite sound insulation mechanism for residential buildings that mimics the shock absorption structure of automobiles. Background Technology

[0002] In current residential buildings, sound insulation performance is one of the key indicators affecting living comfort. Existing residential sound insulation structures mostly adopt a single material such as rock wool and gypsum board stacking design, which only focuses on blocking airborne sound such as talking and television sound, but ignores the impact of structural sound transmission such as footsteps upstairs and vibrations from moving furniture. Vibrations will be directly transmitted through the building structure, resulting in a significant decrease in sound insulation effect.

[0003] Meanwhile, traditional sound insulation structures lack targeted vibration reduction design and cannot offset vibrations through multi-level buffering like automotive shock absorption systems. Furthermore, some structures have limited functionality and require additional fireproofing and decorative layers, resulting in complex installation procedures and low construction efficiency. In addition, the connecting components in existing structures are prone to loosening due to vibration, and the sound insulation and vibration reduction performance deteriorates significantly after long-term use, making it difficult to meet the long-term stability requirements of modern residences.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 This embodiment describes a composite sound insulation mechanism for residential buildings that mimics the structure of a car's shock absorption system. It includes a composite sound insulation layer and multiple sets of support components installed inside the composite sound insulation layer. These support components are arranged in a square pattern. The composite sound insulation layer employs a multi-layer material design, consisting of a metal support plate 1, a centrifugal glass wool layer 2, a honeycomb board 3, a non-woven fabric layer 4, a nitrile rubber pad layer 5, a stainless steel plate layer 6, a fireproof gypsum board layer 7, and a decorative board layer 8, all fixedly connected from top to bottom. The upper surface of the stainless steel plate layer 6 has an installation groove containing a positioning structure that mates with the support components. The metal support plate, located on the top layer, is fixed to the wall via embedded parts and bears the support and load-bearing function of the entire mechanism. The core glass wool layer uses high-density centrifugal glass wool, which has excellent airborne sound absorption capabilities and can initially block high-frequency airborne sound. The honeycomb panel has a honeycomb structure, which uses the resonance effect of the honeycomb holes to further absorb mid- and low-frequency airborne sound, while enhancing the overall structural rigidity. The non-woven fabric layer filters out the tiny vibrations in the sound wave propagation, further improving the sound insulation effect. The nitrile rubber pad layer has high damping characteristics, which can help absorb vibration energy and buffer the rigid contact between the upper and lower structures. The stainless steel plate layer provides structural stability. The fireproof gypsum board layer integrates fireproofing functions, meets building fire protection codes, and does not require an additional fireproof layer. The decorative panel layer is located at the bottom and serves directly as the interior decorative surface, saving the need for subsequent decoration construction steps.

[0018] The support components are evenly distributed inside the composite sound insulation layer near the edge, passing vertically through the centrifugal glass wool layer 2, honeycomb panel 3, non-woven fabric layer 4, and nitrile rubber pad layer 5, finally extending into the mounting groove of the stainless steel plate layer 6 and connecting with the positioning structure. The support components include a fixing head 91 fixed to the bottom of the metal support plate 1, with an upper circular concave plate 92 fixed to the bottom of the fixing head 91. The fixing head and the upper circular concave plate serve as the connection base. A connecting rod 94 is fixed to the center of the bottom of the upper circular concave plate 92, and four sets of first springs 93 are fixed thereon. A sleeve 96 is fixed between the bottoms of the first springs 93. The other end of the connecting rod 94 extends into the interior of the sleeve 96, and a limit block 95 is fixed to its bottom end. The limiting block prevents the connecting rod from coming out of the sleeve. The first spring 93 is evenly distributed between the upper concave plate 92 and the sleeve 96 to form a first-level shock absorption. The bottom of the sleeve 96 is fixed with a lower concave plate 97. A third spring 915 is fixed between the upper concave plate 92 and the lower concave plate 97 and sleeved on the outside of the sleeve 96 to form a second-level shock absorption to help offset unabsorbed vibrations. The bottom of the lower concave plate 97 is fixed with a bottom rod 98. The bottom of the bottom rod 98 is fixed with a sleeve block 99 that extends into the mounting groove and cooperates with the positioning structure. In this way, while playing a certain buffering role, it can also increase the force that drives the stainless steel plate upward through the positioning structure, thereby improving the tightness and firmness of the connection between layers.

[0019] In addition, the positioning structure includes a base plate 910 fixed in the mounting groove, a horizontally placed top column 911 fixed on the top of the base plate 910, the right end of the top column 911 being fitted with a sleeve block 99, the inner wall of the sleeve block 99 being clearance-fitted with the outer wall of the top column 911 to allow for slight displacement and avoid rigid collisions, a recessed block 912 fixed on the top of the base plate 910, a second spring 913 fixed on the inner side of the recessed block 912, and an upper recessed block 914 fixed to the top of the second spring 913 and fixed to the nitrile rubber pad 5, forming a three-stage shock absorption, while elastically positioning the nitrile rubber pad and the stainless steel plate.

[0020] The working principle of the above embodiments is as follows:

[0021] The composite sound insulation layer forms a progressive barrier with eight layers of materials from top to bottom. The top metal support plate fixes the wall and initially blocks sound and provides support. The centrifugal glass wool layer absorbs high-frequency airborne sound. The honeycomb panel absorbs mid- and low-frequency airborne sound and enhances rigidity through the resonance effect of the honeycomb structure. The non-woven fabric layer filters out minor vibrations. The nitrile rubber pad layer absorbs vibration energy with high damping. The stainless steel plate layer ensures structural stability. The fireproof gypsum board layer meets fire protection requirements. The decorative panel layer serves directly as the interior finish. The support components pass vertically through the multi-layer structure and connect to the stainless steel plate layer. The first-level vibration damping is achieved through the fixed head, the upper concave plate, and the first spring. The third spring on the outside of the sleeve forms a second-level vibration damping to offset residual vibrations. The bottom rod and the sleeve block drive the stainless steel plate to improve the tightness of the interlayer connection. The positioning structure is installed in the installation groove of the stainless steel plate layer. The horizontal top column and the sleeve block are fitted with a gap to avoid rigid collisions. The lower concave block, the second spring, and the upper concave block constitute a third-level vibration damping and also provide elastic positioning for the nitrile rubber pad layer and the stainless steel plate layer. Together, they achieve layered treatment and efficient blocking of airborne sound and vibration sound.
