Description
Technical Field
[0001] The utility model relates to the technical field of vibration and noise isolation, in particular to a sound insulation and vibration reduction structure at the connection between a floating floor structure and a drainage ditch. Background Technique
[0002] A floating floor slab is a sound insulation method for building floor slabs. A vibration damping pad is used to separate the floor slab from the rigid connection of the building structure. When the building surface layer is used for a vibration damping platform or vibration damping ground for isolating machine vibration, more professional design is required. If the design is improper and the natural frequency of the vibration damping system is close to the vibration frequency of the machine, not only can it not play a vibration damping role, but also the vibration will be increased, and even the machine and the floor slab structure will be damaged. The impact sound insulation of the floor slab is one of the most difficult sound insulation parts to handle in buildings.
[0003] At present, the sound insulation and vibration reduction structure at the connection between the building structure and the drainage ditch generally uses the method of casting concrete on the glass wool vibration damping cushion layer, and an impact sound insulation effect of more than 20 - 30 dB can be obtained. However, due to the small flat area of the floor slab, there are often drainage ditches with height differences in the floating floor slab area, which destroys the integrity of the floating floor slab and leads to the failure of the sound insulation and vibration reduction effect. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a sound insulation and vibration reduction structure at the connection between a floating floor structure and a drainage ditch, so as to solve the technical problem that the drainage ditch with a height difference destroys the integrity of the floating floor slab and leads to the failure of the sound insulation and vibration reduction effect.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A sound insulation and vibration reduction structure at the connection between a floating floor structure and a drainage ditch, including a structural floor slab, on the top of which there is C30 floating concrete, on which there are a drainage ditch counter-edge and a drainage ditch concrete wall. On the inner side of the drainage ditch counter-edge and the upper surface of the C30 floating concrete, there is a rubber-like waterproof coating. On the top of the rubber-like waterproof coating, there is a concrete casting protective layer. On the top of the concrete casting protective layer, there is a natural rubber vibration isolation and sound insulation pad. On the top of the natural rubber vibration isolation and sound insulation pad, there is a self-adhesive polymer modified asphalt waterproof coiled material. On the top of the self-adhesive polymer modified asphalt waterproof coiled material, there is a cast-in-place C30 reinforced concrete slab. On the top of the cast-in-place C30 reinforced concrete slab, there is a decorative layer. Between the rubber-like waterproof coating and the self-adhesive polymer modified asphalt waterproof coiled material, there is a lateral special vibration and sound insulation board, which is vertically arranged and one side of it is closely attached to one side of the drainage ditch counter-edge, and the bottom of the other side abuts against the concrete casting protective layer.
[0006] By adopting the above technical solutions, the combination of the structural floor slab and the C30 floating concrete forms a basic floating structure, effectively blocking the path of vibration directly transmitted upward from the structural floor slab. The setting of the rubber-state waterproof coating and the concrete casting protective layer not only enhances the waterproof performance of the structure but also further blocks the transmission of vibration. The addition of the natural rubber vibration isolation and sound insulation pad and the special lateral vibration prevention and sound insulation board forms multiple elastic damping layers in the vibration transmission path of the entire structure. These layers will deform during vibration transmission, converting the vibration energy into elastic potential energy, thus significantly reducing the vibration transmission efficiency and reducing the impact of vibration on the superstructure and the surrounding environment.
[0007] Furthermore, self-adhesive polymer modified asphalt waterproof coiled materials are provided on the outer side of the gutter curb, the upper surface of the gutter concrete wall and the C30 floating concrete, and an asphalt sealing block is provided at the top of the gutter curb.
[0008] By adopting the above technical solutions, self-adhesive polymer modified asphalt waterproof coiled materials are laid on the outer side of the gutter curb, the gutter concrete wall and the upper surface of the C30 floating concrete. This measure greatly enhances the waterproof performance of the entire structure. The self-adhesive polymer modified asphalt waterproof coiled material has excellent adhesion and waterproof properties, and can effectively prevent water penetration and protect the structure from water damage.
[0009] Furthermore, a plastering layer is provided inside the area enclosed by the gutter curb, the gutter concrete wall and the C30 floating concrete, and a stainless steel water trough is provided on the plastering layer.
[0010] By adopting the above technical solutions, a plastering layer is provided inside the area enclosed by the gutter curb, the gutter concrete wall and the C30 floating concrete, which can level and beautify this area, making it more in line with the needs of building use. The plastering layer can also provide a certain degree of protection to prevent external factors from damaging the internal structure.
[0011] Furthermore, the model of the natural rubber vibration isolation and sound insulation pad is FZD-50, the thickness of the natural rubber vibration isolation and sound insulation pad is 50 mm thick, the thickness of the self-adhesive polymer modified asphalt waterproof coiled material is 2 mm, the model of the special lateral vibration prevention and sound insulation board is FCD-20, and the thickness of the special lateral vibration prevention and sound insulation board is 20 mm.
[0012] By adopting the above technical solutions, the model of the natural rubber vibration isolation and sound insulation pad is specified as FZD-50, and its thickness is specified as 50 mm. It has excellent vibration isolation and sound insulation performance, can effectively block the transmission of vibration and noise, and improve the comfort and quietness of the building.
[0013] Furthermore, the C30 floating concrete, the cast-in-place C30 reinforced concrete slab, and the self-adhesive polymer modified asphalt waterproof coiled material form a sealed structure to prevent water seepage.
[0014] By adopting the above technical solution, the C30 floating concrete, as the bottom structure, provides a solid foundation for the entire sealed structure with its high strength and density. It can not only bear the weight of the upper structure but also effectively block the water penetration path.
[0015] Furthermore, the natural rubber vibration and noise isolation pad, the C30 floating concrete, the decorative layer, the rubber-state waterproof coating, the self-adhesive polymer modified asphalt waterproof coiled material, and the lateral special vibration and noise isolation board form a floating structure to isolate sound transmission.
[0016] By adopting the above technical solution, the natural rubber vibration and noise isolation pad, as the core layer of the floating structure, has excellent vibration and noise isolation performance. It can effectively absorb and isolate the vibration and noise from the structural floor slab, preventing them from spreading to the upper building, thereby improving the comfort and quietness of the building. The C30 floating concrete, as the bottom layer of the floating structure, is closely combined with the natural rubber vibration and noise isolation pad to jointly form a firm and effective vibration and noise isolation layer. The high strength and density of the C30 floating concrete further enhance the sound insulation effect and can bear the weight of the upper structure to ensure the stability of the entire floating structure.
[0017] Furthermore, the thickness of the natural rubber vibration and noise isolation pad is 50 mm, and the thickness of the rubber-state waterproof coating is 1.5 mm.
[0018] By adopting the above technical solution, the thickness of the natural rubber vibration and noise isolation pad is set to 50 mm, ensuring that it has sufficient elasticity and damping performance. When vibration and noise are transmitted through the structural floor slab, the 50-mm-thick natural rubber vibration and noise isolation pad can effectively absorb and isolate these vibrations and noises, preventing them from continuing to spread to the upper building, improving the comfort and quietness of the building, and protecting the upper building from vibration damage.
[0019] Furthermore, a composite cover plate for drainage is provided at the top of the stainless steel sink.
[0020] By adopting the above technical solution, a composite cover plate for drainage is provided at the top of the stainless steel sink, increasing the practicality and safety of the drainage ditch. The composite cover plate for drainage can cover the stainless steel sink to prevent external sundries from entering the sink interior, causing blockage or damage, thereby ensuring the smoothness and stability of the drainage ditch.
[0021] In summary, the main beneficial effects of the present utility model are as follows:
[0022] 1. The utility model is provided with a natural rubber vibration isolation and sound insulation pad and a special lateral vibration prevention and sound insulation board. Compared with the traditional floating floor treatment process, it is convenient for construction and takes into account the functions of sound insulation, vibration reduction, and waterproofing. The high elasticity of the vibration isolation and sound insulation pad can effectively absorb and buffer the vibration energy from the ground or other structures. When the vibration is transmitted to the rubber pad, the rubber pad will deform and convert the vibration energy into elastic potential energy, thereby reducing the transmission of vibration. The vibration prevention and sound insulation board can also absorb and disperse vibration to a certain extent, reducing the impact of vibration on the floating structure and the surrounding environment. The self-adhesive polymer modified asphalt waterproofing membrane has good waterproof performance. It can closely adhere to the surface of the floating structure to form an effective waterproof barrier to prevent the penetration of moisture. The rubber-state waterproof coating further enhances the waterproof effect to form a continuous waterproof film to prevent the intrusion of moisture, solves the vibration isolation and sound insulation problems in the drainage ditch part, and ensures the integrity of the floating structure;
[0023] 2. The utility model is provided with a composite cover plate for drainage to shield the stainless steel sink, prevent external concrete blocks, etc. from falling into the interior of the stainless steel sink, and reduce the subsequent cleaning workload. BRIEF DESCRIPTION OF THE DRAWINGS
