Description

Technical Field

[0001] The utility model relates to the technical field of building vibration reduction and noise reduction, in particular to a steel spring vibration isolation floating floor slab used in multifunctional indoor venues. Background Art

[0002] The multifunctional indoor basketball (ping-pong, badminton) stadium is a comprehensive building, which includes indoor sports stadiums, conference rooms, libraries, restaurants, commercial areas, leisure areas and other functional areas. The rise of this type of building is due to the development of urbanization, the improvement of people's living standards and the pursuit of a healthy lifestyle.

[0003] 1. For example, a Chinese patent discloses a floating floor (publication number: CN204590521U), including a structural floor, on which a vibration-damping and sound-insulating mortar layer is laid, on which an adhesive layer is arranged, and on which a finishing layer is laid. The floating floor reduces the use of vibration-damping and sound-insulating pads and the occupation of the floor height by the sound-insulating layer by arranging the vibration-damping and sound-insulating mortar layer, effectively avoiding the problem that the protective layer of the floating floor is prone to cracking and hollowing, and the problem that the cross-operation during the construction process is prone to damage, and has good sound insulation effect, has no requirements on the surface of the structural floor, is simple and convenient to construct, and greatly saves manpower and costs.

[0004] 2. For example, a Chinese patent discloses a wide-load double-layer floating floor sound insulation and vibration reduction structure (publication number: CN207714588U), which includes a load-bearing floor layer and a floating floor layer. A double-layer vibration reduction structure is arranged between the load-bearing floor layer and the floating floor layer. The total mass of the floating floor layer and the items on the floating floor layer can vary greatly. As the total mass of the floating floor layer and the items on the floating floor layer increases, the general elastic material will produce a rigid support beyond the range of elastic support, and then lose the effective vibration reduction and sound insulation effect. The double-layer vibration reduction structure sets the height of the shock-absorbing component 2 above the point where the shock-absorbing component 1 is about to reach the critical height of the load, effectively preventing the shock-absorbing component 1 from exceeding the range of elastic support and turning into a rigid support, and effectively expanding the effective frequency range of sound insulation and vibration reduction, which can more effectively reduce the propagation of floor impact sound pressure, thereby greatly improving the sound insulation and noise reduction effect of the floor.

[0005] Multifunctional indoor basketball venues not only meet people's sports needs, but also provide more comprehensive and convenient services. This type of building form can not only save construction land, but also save construction costs and improve economic benefits. Due to the high load intensity and high synchronization rate of basketball and the soft characteristics of large-span buildings, the vibration comfort and secondary noise problems are reduced, affecting the normal use of nearby functional rooms such as conference rooms and libraries. When designing and constructing multifunctional indoor basketball venues, corresponding technical measures need to be taken to reduce the transmission of vibration and noise to ensure the normal use of the building functions.

[0006] Therefore, it is necessary to propose a steel spring vibration isolation floating floor for multi-functional indoor venues to solve the above problems. Utility Model Content
