Description

Technical Field

[0001] The invention relates to the technical field of floor noise reduction, and in particular to a floor noise reduction component. Background Art

[0002] Today's floor slabs are mostly cast-in-place reinforced concrete slabs, including precast panels installed in steel-structured buildings and older brick-concrete structure buildings, all of which do not take into account the issue of building impact noise.

[0003] If there are dance studios or mechanical equipment on the upper floors of office buildings and residential buildings, the huge low-frequency impact noise will seriously affect the health and work and life of residents downstairs.

[0004] Most prefabricated floor slabs in old houses are about 100mm-200mm thick. Due to the thickness and span, the vibrations generated include inaudible infrasound in addition to audible sounds. These infrasounds are transmitted in different directions through the building structure, causing vibrations of other building structures and objects in the room. Infrasound has the characteristics of high energy, long wavelength, and long propagation distance. Some strong infrasound vibrations can also cause irreversible damage to the human body and building structures.

[0005] High-frequency vibrations are mostly the sound of people walking, such as the collision of high heels and floors, mechanical noise, objects falling, furniture pushing, etc. This noise is transmitted downward through the floor, causing the air below to resonate, and is eventually heard by the human ear, causing the residents to be disturbed by the noise.

[0006] For existing buildings, most ways to reduce impact noise are to lay carpets, install wooden floors, or lay rubber shock-absorbing blocks on the ground to isolate noise. However, this noise isolation method cannot effectively absorb impact noise of various frequency bands, especially low-frequency noise, which is even more difficult to absorb.

[0007] Although the method of using multi-layer shock-absorbing floors can absorb some noise more effectively, it also limits the use of multi-layer shock-absorbing floors because it occupies more floor height.

[0008] The existing floor includes multi-layer floor, which is thicker and has a shorter lifespan, and the smaller indoor height is not conducive to installing a thicker shock-absorbing structure. Summary of the invention

[0009] To this end, the present invention provides a floor noise reduction component to solve the above-mentioned problems in the prior art.

[0010] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] A floor noise reduction assembly, comprising:

[0012] The panel has a supporting structure on its lower side, the supporting structure is a triangular iron with the tip pointing downward, the outer side of the supporting structure is provided with a sound-absorbing material, and the sound-absorbing material is tightly connected to the panel by extrusion or bonding, the lower side of the sound-absorbing material is provided with a ground leveling layer, the ground leveling layer forms a relatively soft and sparse cushion layer between the sound-absorbing material and the floor slab, and the outer sides of the panel, the supporting structure, the sound-absorbing material and the ground leveling layer are all provided with surrounding fillers to isolate the direct conduction of vibration.

[0013] Furthermore, the panel may be selected from: steel plate, iron plate, copper plate, lead plate, aluminum alloy plate, cement plate.

[0014] Furthermore, the support structure may also include a shock absorbing mechanism, a spring, and a support foot.

[0015] Furthermore, the sound absorbing material may be rock wool, porous material, foam material, or rubber material.

[0016] Furthermore, the material of the ground leveling layer may be cement mortar.

[0017] Furthermore, the support structures are crisscrossed and installed under the panel in a matrix or irregular shape and irregular placement.

[0018] Furthermore, the panels may be spliced ​​in irregular geometric shapes.

[0019] Furthermore, the irregular panel is provided with wavy or small round holes.

[0020] Furthermore, the shock absorbing mechanism includes a mounting base, an inner side of the mounting base is provided with an inner cavity, and a mounting plate is installed on the inner side of the inner cavity, a mounting column is fixed to the upper end of the mounting plate, and a covering sheet is installed on the outer side of the mounting column, and the longitudinal section of the inner cavity is arranged in an inverted trapezoidal shape.

[0021] Furthermore, the outer side of the mounting plate is inclined, and auxiliary cones are installed on the outer sides of the mounting column, the cover sheet and the mounting base.

[0022] The present invention has the following advantages:

[0023] The high-density steel plate structure can block noise, the smooth surface can reflect noise, the elastic structure can absorb low-frequency noise, and the sharp-angled support structure can change the vibration frequency and conduction direction of sound, which will eventually be absorbed by the shock-absorbing material and converted into heat energy for consumption.

[0024] The ultra-thin structure, relatively low price and easy material acquisition are another main feature of the present invention in addition to achieving the shock-absorbing effect. It can also be easily installed in a completed building, providing more flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1-3 As shown, a floor noise reduction assembly in an embodiment of the first aspect of the present invention includes:

[0032] The full-covered panel 1, as an option, such as steel plate, iron plate, copper plate, lead plate, aluminum alloy plate or cement plate, can play the role of isolating and reflecting sound. The flat surface will reflect part of the sound. Due to its large mass, the energy required to generate vibration is correspondingly large, and it is difficult to generate self-vibration and conduct vibration.

[0033] The supporting structure 2 fully spreads on the lower side of the panel 1. The supporting structure 2 is mainly a triangular iron with the tip pointing downward. As an optional solution, it also includes various forms of supports, including but not limited to springs, shock absorbing mechanisms 6, supporting feet in geometric shapes such as circles and triangles, and all materials that can be used as supports to create isolation gaps and spaces between the panel 1 and the original building floor.

[0034] This structure can repeatedly vibrate, reflect and transmit low-frequency vibrations within the structure, eventually transforming them into high-frequency vibrations, which are absorbed by itself or other materials and eventually consumed as heat energy. At the same time, it can also reduce the direct contact area with the lower floor slab and reduce the vibration transmission between objects.

[0035] The sound-absorbing material 3 is fully spread on the outside of the supporting structure 2. It fully fills the space between the floor and the panel 1 and is closely connected to the panel 1 by extrusion or bonding. The material includes but is not limited to rock wool, porous materials, foam materials, rubber materials and other materials that can absorb surface vibrations. The material is soft and has a low density. It can absorb vibrations and convert them into heat energy. This material exists in a single or multi-layer combination according to the situation.

[0036] The ground leveling layer 4 is arranged on the lower side of the sound-absorbing material 3. The fluidity or elasticity of the ground leveling layer 4 is used to form a relatively soft and sparse cushion layer between the supporting structure 2 and the floor. The specific method is to install the support feet of the panel on the floor before the cement mortar dries, and use the fluidity of the cement mortar or the elasticity of the elastic material to fill the horizontal tolerance caused by the process problem, so that each part where the panel layer and the floor are connected will not be suspended. At the same time, it also serves the purpose of fixing the surface layer in the horizontal direction. The materials of this layer include but are not limited to cement mortar, various self-leveling, the foot wrap of the support foot, the base of the shock absorber or the structure for adjusting the level, etc.

[0037] The surrounding filler 5 is used to fill the gap between the panel 1 and the wall, including but not limited to elastic materials such as rubber, foaming materials, wood, plastic, etc. The filler has the functions of moisture-proof, sound insulation, shock absorption, dustproof, sealing, etc. It can have no rigid connection between the panel and the building envelope, and isolate the direct conduction of vibration.

[0038] The technical effects achieved by the above embodiments are as follows: the high-density steel plate structure can block noise, the smooth surface can reflect noise, the elastic structure can absorb low-frequency noise, and the irregular geometric shape and sharp-angled support structure 2 can change the vibration frequency of the sound and the direction of sound conduction, which will eventually be absorbed by the shock-absorbing material and converted into heat energy for consumption.

[0039] Example 2

[0040] like Figure 1 and Figure 2As shown, a floor noise reduction assembly includes all the contents of embodiment 1, and in addition, the supporting materials 2 can be crisscrossed, or installed under the panel 1 in a matrix or irregular shape and irregular placement. The purpose is that when the vibration of the full-covered panel 1 is caused, the distances between the irregular supporting materials 2 are different, the spans of the panel 1 are also different, and the vibration frequencies generated by the panel 1 are also different. In this way, vibrations of different frequencies can interfere with each other, the vibration waves collide with each other, the frequencies change, and are thus consumed by themselves, offset each other, or absorbed by other sound-absorbing materials.

[0041] Example 3

[0042] like Figure 1 and Figure 2 As shown, a floor noise reduction assembly includes all the contents of Example 2. In addition, the panel 1 can also be in an irregular geometric shape. In order to allow the vibrations generated in life to eventually offset each other and collide inside the surface layer, and the frequency changes. Finally, it is absorbed by other materials. The panel is obtained by splicing irregular geometric shapes. Avoid using shapes such as circles, positive directions, rectangles, etc. that are prone to resonance and self-excited oscillation at specific frequencies.

[0043] Example 4

[0044] like Figure 1 and Figure 2 As shown, a floor noise reduction component includes all the contents of Example 3. In addition, wave-shaped or small round holes are opened on the irregular panel 1 to change the vibration frequency, thereby making it easier for vibrations to offset each other in the surface layer or increase the vibration frequency.

[0045] Example 5

[0046] like Figure 1 and Figure 2As shown, a floor noise reduction assembly includes all the contents of Example 3. In addition, the shock absorbing mechanism 6 includes a mounting base 601, an inner cavity 602 is opened on the inner side of the mounting base 601, and a mounting plate 604 is installed on the inner side of the inner cavity 602. A mounting column 603 is fixed to the upper end of the mounting plate 604, and a cover sheet 605 is installed on the outer side of the mounting column 603. The longitudinal section of the inner cavity 602 is set in an inverted trapezoidal shape, and the outer side of the mounting plate 604 is set in an inclined manner, so that when the mounting column 603 descends, in addition to being affected by the damping oil The cover sheet 605 is not limited by the gap between the outer side of the mounting plate 604 and the inner wall of the inner cavity 602, thereby gradually reducing the flow efficiency of the damping oil and further increasing the resistance. The cover sheet 605 can be used to increase the cavity between the cover sheet 605 and the mounting base 601 in a single space, thereby increasing the structure of mutual vibration offset. Auxiliary cones 606 are installed on the outer sides of the mounting column 603, the cover sheet 605 and the mounting base 601 to increase the irregular shape between the panel 1 and the sound-absorbing material 3, thereby further increasing the sound absorption and noise reduction capabilities.
