Description

Multi-level overhead sound-absorbing floor

This creation belongs to the field of building interior decoration, especially refers to a multi-level elevated sound-absorbing floor slab, which is used to set the space between the building structure floor and the floor decoration layer to effectively solve the problem of transmission of air and impact sound from the building structure floor. By.

At present, common high-rise buildings are only designed to be used as a decoration layer (tile or floor) on the original structural layer (structural plate and building floor). Therefore, the air and impact sound generated on the decoration layer will be It is directly transmitted from the structural plate to the building floor structure through the conduction method, and then affects the living quality of other floors of the high-rise building. This is the main source of airborne noise between high-rise buildings that generally use reinforced concrete floors. It is also the most stigmatizing problem of collective housing.

However, the current construction methods of high-rise buildings are introduced as follows: 1. Reinforced concrete structure: This is the most common construction method in general. The decoration layer is only applied on the surface of the structural layer. Therefore, the air generated on the decoration layer Sounds and impact sounds will be transmitted through the structural layer and affect the living quality of other floors. 2. A fixed buffer material is added between the reinforced concrete structure and the floor decoration layer. This method is mostly used after the main structure of the building is completed. The fixed buffer material is added between the structural layer and the decoration layer, which uses the fixed buffer. The structural layer is separated from the decoration layer to reduce air and impact sounds transmitted directly to other floors through the structural board; however, the fixed cushioning material (such as foamed polystyrene, glass wool cushioning material or Rock wool buffer material), because it does not have sufficient support, the floor decoration material on it cannot bear the load of household equipment, that is, it is deformed or damaged. And rubber Although the fixed cushioning material has a certain rigid strength, the durability of rubber is far less than the service life of cement-based materials. Therefore, when the rubber ages, the rigid strength disappears, and the floor decoration material cannot bear the load of household equipment, which results in Deformation or damage. 3. Poly Dragon Ball Hollow Floor: It is the current construction method of new buildings. The sound-absorbing material and the floor structure of the main body are cast in one piece. As a sound-absorbing material, a plurality of ball-shaped polyrons are covered on the structural layer. Inside, the non-isolated sound reduction structure allows air and impact sounds to be transmitted directly to other floors through this structural layer; however, currently, the ball-type floor slabs on the market, due to the process of placing concrete, such balls Between the upper and lower surfaces, the type of polyline is often hollow or honeycomb due to the difficulty of pouring and tamping. Therefore, it has a great impact on the strength of the structural layer. 4. One-piece roof insulation and sound absorption construction method and structure: It is also the construction method of new buildings. It is also the construction of the sound insulation material and the floor structure of the building body as a whole. The non-isolated sound insulation structure is used as the sound insulation material. A Polyurethane board is wrapped in the integrally poured structural layer, so that air and impact sounds are transmitted directly through the structural layer to other floors. 5. Construction method of sound damping floor and sound damping floor (TW1008151): It uses fixed cushioning material to isolate the structural layer from the decoration layer to reduce noise and impact sound transmitted directly to other floors through the structural board; Avoid the problem that the foamed polystyrene board of the sound damping layer cannot bear the load of the household equipment, causing the deformation or damage of the floor decoration layer. A rubber cylinder is used as the support system for lamination, and then cement mortar is laminated thereon. In addition, in order to ensure the thickness of the protective layer in the laminate, cushions need to be placed between the rubber cylinder and the reinforcing mesh to cause rubber Cylinder-like bodies, spacers, and reinforcing meshes are separated and formed in a non-integrated state. The process is complicated and the spacers are easy to fall off, causing the problem of losing the protective layer of the reinforcement mesh. Although rubber has a certain rigid strength, the durability of rubber is far lower than the useful life of cement-based materials. Therefore, when the late rubber cylinder ages and causes the rigid strength to disappear, the cement mortar laminate cannot support the load of household equipment and floor decoration The layer then becomes deformed or damaged. In addition, the method adopts a single sound damping layer method. Experimental results show that the sound reduction effect is far lower than the multi-layer sound reduction floor of this creation.

In addition, the above construction methods all embed hydropower pipelines in the structural layer, and often ignore the structural strength loss caused by these hydroelectric pipelines replacing the concrete volume, and then affect the structural strength and durability of the structural layer; secondly, When these water and electricity pipelines encounter failure and must be repaired, the original structural layer must be destroyed for repair. In this way, not only the durability of the original structural layer is impaired, but also how to repair or share the upper and lower floors often Disputes arising from maintenance costs.

Considering that there are still imperfections in the conventional construction method, how to effectively solve the problem of air sound and impact sound of the current structural layer of high-rise buildings, while taking into account the sturdiness and safety of the building structure. After continuous research and development for a long time, a multi-level overhead sound-absorbing floor was finally developed to effectively solve the problem of sound attenuation at the structural layer.

Furthermore, since this creation is not directly related to the structural layer, it can be combined with water and electricity. Pipeline construction shall be carried out with the convenience of subsequent hydropower pipeline construction in mind, and achieve the effect of sustainable construction.

In an embodiment, when the creation of the first sound reduction layer is performed, the range of the sound reduction to be applied includes the ground and a wall extending a height adjacent to the ground, and the structure of the interior space will not Directly connected, thereby reducing the problem of direct transmission of air and impact sounds.

Furthermore, at least one pipeline channel is provided on the second sound-reduction floor of the multi-layer elevated sound-reduction floor slab of the present creation, so as to pass through various water pipe lines, power lines or signal lines. In addition, the surface layer of the multi-layer elevated sound-absorbing floorboard in this work can be provided with an elevated support body that can support the floor decoration layer through structural analysis. This work also has a floor decoration layer, which is laid on the floor with a decorative material. The top surface of the surface layer is formed.

In another embodiment, in order to increase its sound reduction and sound absorption effects, the second sound reduction layer is made of expanded polystyrene. In addition, the cement-based slurry system of the surface layer is mixed with a plurality of sound-absorbing material granules at a set ratio to form a light-weight cement-based slurry, which has a sound reduction effect. In addition, the reinforcing mesh layer is made of reinforced mesh or barbed wire to increase the structural strength of the surface layer.

This design uses a multi-layered sound reduction structure to separate the floor decoration layer from the building's floor structure. Therefore, when air and impact sounds on the floor decoration layer are transmitted to the surface layer, the second sound reduction layer and When the first sound-absorbing layer is used, cement-based slurry, foamed polystyrene board (or glass wool buffer material or rock wool buffer material, or other sound-absorbing material) and sound-absorbing material can effectively disperse and block air. Sound and impact sounds in the interior space, reducing air and impact sounds through the building's floor The structure is passed to the adjacent house and other floors, which improves the lack of traditional sound reduction methods.

Please refer to FIGS. 1, 2, 3 and 4, which are a schematic structural diagram and a partial cross-sectional view of a preferred embodiment of the creation, a flowchart of steps during the implementation, and a structural diagram of another preferred embodiment, respectively. As shown in Figures 1 and 2, the multi-layer elevated sound-absorbing floorboard 1 referred to in this creation includes a first sound-absorbing layer 11, a plurality of hollow feet 12, a second sound-absorbing layer 13, and a stiffening mesh layer. 14 and a surface layer 15 are used to install and install in an indoor space of a high-rise building to effectively solve the problems of floor sound and impact sound transmission.

The first sound-absorbing layer 11 is formed by laying a sound-absorbing material at a range where sound reduction is to be applied in the indoor space to form the first sound-absorbing layer 11. It should be noted that the sound-absorbing material is selected from, for example: The sound absorption principle of one of the porous materials such as glass fiber cotton, blanket, foamed cotton, and expanded polystyrene is to use sound waves to penetrate the pores of the sound absorbing material. The friction and resistance of air molecules, as well as the mechanical vibration of small fibers, transform sound energy into thermal energy. The sound absorption coefficient of this sound-absorbing material gradually increases from low to high frequencies, so it has a better sound absorption effect on high and medium frequencies. The range of sound reduction to be included in this creation includes the ground and a wall extending adjacent to the ground. It can also prevent air or impact sounds from being transmitted to other adjacent rooms through the wall.

The hollow feet 12 are arranged in a hollow tubular structure, and the hollow feet 12 are vertically spaced and vertically arranged in the setting range of the first sound reduction layer 11 with the openings facing upward.

The second sound-absorbing layer 13 is selected from a plate-like structure made of one of porous materials such as glass fiber wool, rock wool, and expanded polystyrene, and is used to fill the first sound-absorbing layer. Within the range of 11 and the second sound reduction layer 11 is provided with a plurality of perforations 131 corresponding to the hollow feet 12, The hollow feet 12 are placed therein, and the height of the hollow feet 12 is set to correspond to the thickness of the second sound reduction layer, which is basically higher than the thickness of the second sound reduction layer 13 as Consider to reserve the thickness of the protective layer of the stiffener layer in the surface layer. It should be noted that the second sound reduction layer 13 is provided with a plurality of pipeline passages 132 for passing through various water pipe lines, power lines or signal lines.

The stiffening mesh layer 14 is made of reinforced mesh or barbed wire for laying on the top of the hollow foot 12 as a fixing frame for the stiffening mesh layer 14 to prevent the stiffening mesh layer 14 from directly attaching to the second sound-damping layer 13. There is no problem with the protective layer on the surface, and the stiffening mesh layer 14 is hollow, so that the interior of the hollow feet 12 is kept in communication with the surface layer 15.

The surface layer 15 is filled with a cement-based slurry 151 on the top of the second sound-absorbing layer 13 and in the hollow feet. The surface layer 15 is formed after it is dried, and the top surface of the surface layer 15 is flattened. Processing, because the cement-based slurry 151 has a moderate fluidity, it can flow into the hollow feet 12 during application, and can be used as the solid feet of the surface layer 15 after hardening. It should be noted that, in order to further improve the sound absorption effect, this creation is particularly mixed with the cement-based slurry 151 of the surface layer 15 by mixing a plurality of sound-absorbing material granules 152 at a set ratio to form a special light-weight cement material. The slurry can be used to improve the sound absorption effect. It can also be directly composed of cement mortar material. In various embodiments, the surface layer can be directly used as the surface of the floor. The same design as the traditional construction method can also effectively reduce its overall structure. thickness of.

As shown in Figs. 3 and 4, the steps in the creation of this creative process include: S1: laying the first sound-absorbing layer 11 with sound-absorbing material at the range where the sound reduction is to be applied; S2: on the first sound-absorbing layer The second sound-absorbing layer 13 is laid on top; S3: the hollow feet 12 are installed in the perforations 131 of the second sound-absorbing layer 13; S4: the stiffening mesh layer 14 is laid on the second sound-absorbing layer The tops of the hollow feet 12 on 13; S5: the surface layer 15 with structural strength is poured on the second sound-absorbing layer 13 with cement-based slurry; S6: after the surface layer 15 is hardened, it is applied according to design requirements The floor decoration layer 16, which is different from the design of the surface layer 15, is formed by laying a decorative material on the top surface of the surface layer. Some decorative materials include tiles, wooden floors, or other reinforced flooring materials that are often visible. By adding the floor decoration layer 16, the thickness can also be increased, which also has a considerable effect on damping and noise reduction. Therefore, through the above The structure and construction method can effectively solve the problems of air sound and impact sound of the floor of the building, so as to achieve the effect of sound reduction.

To sum up, the multi-layer elevated sound-absorbing floor slab 1 of this creation can be used with traditional construction methods, so it can be used in new buildings or existing buildings, mainly through the surface layer 15, the second sound-absorbing layer 13 and The first sound reduction layer 11 effectively disperses and blocks the sound waves of air sound and impact sound, and prevents air sound and impact sound from being transmitted to adjacent rooms and other floors through the floor structure of the building, thereby improving traditional buildings or other sound reduction. Due to the lack of construction methods, the surface layer 15 can be used as the floor surface, and the additional thickness of the floor decoration layer 16 is not required to achieve the purpose of reducing the overall thickness. In order to further save manufacturing costs, the first sound reduction layer 11 can also be laid only on the bottom of each of the hollow feet 12, and also has a sound reduction effect. In addition, this creation uses the raised hollow foot 12 to replace the rubber pad used in the previous sound damping method. The construction process is relatively simple, similar to the traditional floor slab application method, and there is no loss of steel mesh. The problem of the protective layer, and the hollow feet 12 are filled into a single-piece design formed by filling the base of the surface layer 15 after grouting. Its durability is similar to that of the structural material, and its overall strength is improved. Effectively provide the required load strength of the floor decoration layer 16. This creation is also not like rubber pads, which will cause the rigid strength to disappear due to aging, causing problems such as deformation or damage to the floor decoration layer 16, thereby improving the lack of traditional sound reduction methods. . Moreover, the pipeline passage 131 in the second sound-absorbing layer 13 can accommodate various water pipe lines, power lines or signal lines therein, as much as possible, conforming to the solid structure of the original design, increasing the structural shock resistance and the service life. In the event of a failure, the original structure does not need to be damaged, and maintenance and testing will not cause troubles and disputes between the upper and lower floors. The purposes of open-pipe construction and sustainable construction are completely realized.

However, the above are only the preferred embodiments of this creation, and are not intended to limit the scope of implementation of this creation. Therefore, those who have ordinary knowledge in the technical field or are familiar with this technology Those who make equivalent replacements of various elements, or make more re-series changes, all equal changes and modifications made without departing from the spirit and scope of this creation shall all be covered by the patent scope of this creation.
