Description

Multi-layer elevated sound-absorbing floor slab

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

At present, the common high-rise buildings are only designed by applying a decoration layer (tile or floor) on the original structural layer (structural slab and building floor). Therefore, the air and impact sounds generated on the decoration layer can pass through the city. It is directly transmitted from the structural plate to the building floor structure through the conduction method, which affects the living quality of the other floors of the high-rise building. This is the main source of airborne sound interference between each floor in the high-rise building that generally uses reinforced concrete floors. It is also the most controversial issue of collective housing.

However, the current construction methods of high-rise buildings are described as follows: 1. Reinforced concrete structure: This is the most common construction method. It is only used as a decoration layer on the surface of the structural layer. Therefore, the air generated on the decoration layer Sound and impact sound 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 the transmission of air and impact sounds directly to other floors through the structural board; however, the fixed cushioning material of porous materials (such as: (Expanded polystyrene, glass wool cushioning material or rock wool cushioning material), because it does not have sufficient supporting force, the floor decoration material on it cannot bear the load of the household equipment, that is, it is deformed or damaged. Although the fixed cushioning material of rubber has a certain rigidity, the durability of rubber is much lower than the service life of cement-based materials. Therefore, when the rubber ages late, the rigidity disappears, and the floor decoration material cannot withstand the household equipment. Load, that is, the problem of deformation or damage. 3. Poly Dragon Ball Hollow Floor Slab: It is the construction method of the new building at present. The sound-absorbing material is integrated with the floor structure of the main body of the building, and a plurality of spherical Styrofoam as the sound-absorbing material is coated on the structural layer. Inside, the non-isolated sound attenuation structure allows air and impact sounds to be directly transmitted to other floors through the structural layer; however, the current Styrofoam spherical floor slabs, due to the concrete pouring process, these balls Between the upper and lower surfaces, the type of Styrofoam often produces hollow or honeycomb due to the difficulty of pouring and tamping. Therefore, it has a great influence on the strength of the structural layer. 4. One-piece roof heat insulation and sound absorption construction method and structure: it is also the construction method of new buildings, and it is also a sound insulation material and the floor structure of the main body of the building are integrally cast, and the non-isolated sound insulation structure is used as the sound insulation material The Styrofoam board is wrapped in the integrally cast structural layer, so that air sound and impact sound can be directly transmitted to other floors through the structural layer. 5. Construction method of damping floor and damping floor (TW1008151): It uses fixed buffer material to isolate the structural layer from the decoration layer to reduce noise and impact sound directly transmitted to other floors through the structural board; To avoid the problem that the sound damping layer expanded polystyrene board cannot bear the load of the household equipment, causing the floor decoration layer to deform or damage. The rubber cylinder is used as the support system for the lamination, and the cement mortar is laminated on it. In addition, in order to ensure the thickness of the protective layer in the lamination, a cushion block needs to be placed between the rubber cylinder and the steel mesh to cause rubber Cylindrical body, cushion block and reinforcement mesh are separated and non-integrated. The process is complicated and the cushion block is easy to fall off, which causes the problem of losing the protection layer of the reinforcement mesh. Although rubbers have certain rigid strength, the durability of rubbers is much lower than the service life of cement-based materials, so when the late rubber cylinders Aging causes the rigid strength to disappear, the cement mortar layer cannot bear the load of household equipment, and the floor decoration layer is deformed or damaged. In addition, the construction method adopts a single sound-dampening method, and the experimental results show that the sound-damping effect is far lower than the double-layer sound-damping floor slab of this creation.

Furthermore, the above construction methods are pre-buried hydroelectric pipelines in the structural layer, often neglecting the structural strength loss caused by these hydroelectric pipelines replacing the concrete volume, which in turn affects the structural strength and durability of the structural layer; second, When these hydropower pipelines encounter failures and must be repaired, they must be destroyed to repair the original structural layer. In this way, not only the durability of the original structural layer is reduced, but also often how to repair or share the upper and lower floors. Disputes arising from maintenance costs.

In view of the fact that there are still imperfections in the conventional construction method, how to effectively solve the problems of air sound and impact sound in the structural layer of the current high-rise building, and take into account the solidity and safety of the building structure. Continuous research and development for a long time, and finally developed a multi-story elevated sound-absorbing floor slab, in order to effectively solve the problem of sound attenuation of the structural layer.

One purpose of this creation is to provide a multi-story elevated sound-absorbing floor slab, in order to use a first sound-absorbing layer, a plurality of hollow feet, a second sound-absorbing layer, a stiffening mesh layer and a surface layer, its use Installed in one of the indoor spaces of tall buildings to effectively solve the problems of airborne sound and impact sound transmission on the floor to improve the quality of life of the residents; furthermore, because this creation is not directly connected to the structural layer, it can be combined with hydropower The pipeline is constructed in open pipe, taking into account the convenience of subsequent hydropower pipeline construction, and achieving the effect of sustainable construction.

In one embodiment, when the first sound-absorbing layer is applied in this creation, the range of the sound-absorbing layer includes a wall extending a height around the ground and the adjacent ground plane, and the structure of the indoor space does not Direct connection, thereby reducing the problem of direct transmission of air and impact sounds.

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

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

The present invention separates the floor decoration layer from the floor structure of the building by a multi-layer sound attenuation structure. Therefore, when air sound and impact sound on the floor decoration layer are transmitted to the surface layer, the second sound reduction layer and The first sound-absorbing layer can be made of cement-based slurry or expanded polystyrene board (Or glass wool cushioning material or rock wool cushioning material, or other sound-absorbing materials) and sound-absorbing materials are effectively dispersed and block air and impact sounds in the indoor space, reducing air and impact sounds through the floor structure of the building Passed to the neighboring room and other floors, thereby improving the lack of traditional sound reduction methods. In addition, as mentioned above, the creation can also directly install water pipes, power lines or signal lines in the second sound-absorbing layer, and after the structure of the creation is completed, it can be used for floor decoration as traditional construction methods. Layer to increase the overall beauty and texture; it can also reduce the overall thickness by reducing the thickness of the second sound-absorbing layer and the surface layer used to replace the floor decoration layer to achieve the same requirements and implementation methods as traditional construction methods . Moreover, since this design adopts the design of a plurality of hollow feet as above, if the cost is saved, the first sound-absorbing layer may also be laid only under each of the hollow feet. In addition, the raised hollow feet replace the pads, the process is simple, and there will be no problem of losing the protective layer of the reinforcement mesh. The hollow feet are filled into the base of the surface layer after grouting to form the integrally formed surface layer Design; and, the hollow foot is made of cement-based material, and its service life is similar to the structure material. There will be no aging of rubber pads and the rigid strength will disappear, so that the floor decoration layer will be deformed or damaged, which will improve the knowledge.

Please refer to FIGS. 1, 2 and 3, 4, which are respectively a schematic structural view and a partial cross-sectional view of a preferred embodiment of the creation, as well as a flowchart of steps during implementation and a schematic structural view of another preferred embodiment. As shown in Figures 1 and 2, the multi-story elevated sound-absorbing floor 1 referred to in this work 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 15 are used to set up an indoor space installed in a high-rise building to effectively solve the problems of air sound and impact sound transmission on the floor.

Wherein the first sound-absorbing layer 11 is laid with a sound-absorbing material at a range in the indoor space to be subjected to sound attenuation to form the first sound-absorbing layer 11, it should be noted that the sound-absorbing material is selected from: One of the porous materials such as glass fiber cotton, blanket, foamed cotton and expanded polystyrene, the principle of sound absorption is to use sound waves to penetrate into the pores of the sound absorbing material, and the pores are mostly open holes that penetrate each other. The friction and resistance of air molecules, as well as the mechanical vibration of fine fibers, convert sound energy into heat energy. The sound absorption coefficient of this kind of sound absorbing material gradually increases from low frequency to high frequency, so it has a good effect on sound absorption at high and medium frequencies. The scope of this creation to be used for sound reduction includes a wall extending a height around the ground and the adjacent ground plane, and can also prevent air or impact sound from being transmitted to other neighboring rooms through the wall.

The hollow feet 12 are arranged as a hollow tubular structure, and the hollow feet 12 are spaced and vertically arranged in the installation range of the first sound-absorbing layer 11 with the opening 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 for filling the first sound-absorbing structure Within the range of the layer 11, and the second sound-absorbing layer 13 is provided with a plurality of perforations 131 corresponding to the hollow feet 12 to place the hollow feet 12 therein, so that the hollow feet 12 The height corresponds to the thickness of the second sound-absorbing layer. Basically, the thickness is higher than the thickness of the second sound-absorbing layer 13 to reserve the thickness of the protective layer of the stiffening mesh layer in the surface layer. It should be noted that the second sound-absorbing layer 13 is provided with a plurality of pipeline channels 132 for passing various water pipe lines, electric power lines or signal lines.

The stiffening mesh layer 14 is made of reinforced mesh or barbed wire, which is used to lay on the top of the hollow foot 12 as a fixing frame of the stiffening mesh layer 14 to prevent the stiffening mesh layer 14 from being directly attached to the second sound-absorbing layer 13 There is no problem of the protective layer on the surface, and the stiffening mesh layer 14 is hollowed out, so that the inside of the hollow feet 12 keeps communicating 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 the hollow feet, and after drying, the surface layer 15 is formed, and the top surface of the surface layer 15 is flattened Treatment, since the cement-based slurry 151 has a moderate fluidity, it can flow into the hollow feet 12 during application and harden as a solid foot of the surface layer 15 after hardening. It should be noted that in order to further improve the sound absorption effect, this creation is especially mixed with a plurality of sound absorption material pellets 152 in a set ratio in the cement paste 151 of the surface layer 15 to form a special light particle cement system In order to improve the sound absorption effect, it can also be directly composed of cement mortar material. In various embodiments, the surface layer can be used directly 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 again, the steps during the construction of the composition include: S1: laying the first sound-absorbing layer 11 using sound-absorbing material at the sound-absorbing range; S2: applying the first sound-absorbing layer Laying the second sound-absorbing layer 13 on top; S3: installing the hollow feet 12 in the perforations 131 of the second sound-absorbing layer 13; S4: laying the stiffening mesh layer 14 on the second sound-absorbing layer The tops of the hollow feet 12 on 13; S5: The surface layer 15 with structural strength is filled with cement-based slurry on the second sound-absorbing layer 13; S6: After the surface layer 15 is hardened, it is implemented according to design requirements The floor decoration layer 16, of which the floor decoration The layer 16 is different from the design of the surface layer 15 and is formed by laying a decorative material on the top surface of the surface layer. These decorative materials include often-visible tiles, wooden floors or other reinforced floor boards. The floor decoration layer 16 can also increase its thickness, and also has a considerable effect on vibration and sound attenuation. Therefore, through the above structure and construction method, it can effectively solve the problems of air sound and impact sound of the floor of the building to achieve the reduction The effect of sound.

In summary, the multi-story 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-absorbing layer 11 effectively layer-by-layer disperses and blocks the sound waves of air sounds and impact sounds, preventing air sounds and impact sounds from being transmitted to the neighboring rooms and other floors through the building's floor structure, thereby improving traditional buildings or other sound reduction Due to the lack of construction methods, the surface layer 15 can be used as the surface of the floor, without the need to add the floor decoration layer 16 to reduce the overall thickness. In order to further save the manufacturing cost, the first sound-absorbing layer 11 can also be laid only on the bottom of each hollow foot 12, which also has a sound-absorbing effect. In addition, this creation uses the raised hollow foot 12 to replace the rubber cushion used in the conventional sound reduction method. The process of construction is relatively simple, similar to the traditional floor slab, and there is no loss of reinforcement mesh. The problem of the protective layer, and the hollow base 12 fills into the base of the surface layer 15 after grouting to form an integrated molding design, its durability is similar to that of the structural material, and its overall strength is also improved. Effectively provide the required load strength of the floor decoration layer 16, this creation is not like the rubber pad will lose its rigid strength due to aging, causing the floor decoration layer 16 to deform or damage and other problems, 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 far as possible in accordance with the solid structure of the original design, to increase the seismic resistance and service life of the structure, in the future In the event of failure, there is no need to destroy the original structure. Maintenance and inspection will not cause troubles and disputes between the upper and lower floors, and the purpose of open pipe construction and sustainable construction is completely achieved.
