Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically relating to an anti-resonance sound insulation floor slab. Background Technology

[0002] The long-term hazards of floor slab noise and vibration are mainly manifested in three aspects: 1. Structural damage: Continuous vibration accelerates the fatigue of building materials, causing problems such as cracks and deformation. Especially for old buildings or buildings with structural defects, it may exacerbate damage or even lead to the risk of collapse. Resonance may also induce brittle structural failure. 2. User discomfort: Floor slab impact noise is a common form of noise pollution (such as in electronic music theaters and KTVs in commercial buildings). Long-term exposure can easily cause insomnia, headaches, mental stress, and other physical and mental problems, significantly reducing the quality of life. It can also cause complaints due to disturbance to the lives of downstairs and surrounding residents, disrupting social harmony. The harm is especially great to vulnerable groups. 3. Safety hazards: Strong vibrations may damage equipment, pipes, wires, and other facilities in the building, thereby triggering secondary disasters such as fires and floods. Floor slab resonance is mainly caused by the regular vibration of the upper live load. In existing technologies, floating floor slabs or sound insulation cotton are usually used. Although these structures have certain sound insulation, vibration reduction, and heat insulation properties, they have little effect on the resonance problem and can hardly play a role in the force transmission path of dynamic load to static load.

[0003] Therefore, it is essential to develop an anti-resonance soundproof floor slab. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an anti-resonance sound insulation floor slab.

[0005] The purpose of this utility model is achieved as follows: it includes a concrete floor slab, air springs, vibration damping and sound insulation pads, a diaphragm, a cement mortar layer, and a decorative floor surface. The concrete floor slab, vibration damping and sound insulation pads, diaphragm, cement mortar layer, and decorative floor surface are arranged sequentially from bottom to top. Several air springs are provided between the concrete floor slab and the vibration damping and sound insulation pads. The air springs are arranged in rows and columns, with a spacing of 20cm to 50cm between adjacent air springs. Air springs adjacent to the corner of the wall are arranged flush with the corner. The bottom of the air spring is bonded to the concrete floor slab, and the top of the air spring is bonded to the vibration damping and sound insulation pad. The edge of the vibration damping and sound insulation pad covers the corner of the wall, and the edge of the vibration damping and sound insulation pad extends upward to cover the wall surface.

[0006] Preferably, the air spring bladder has a diameter of 10cm and is a conventional foldable elastic rubber-wrapped nitrogen bladder with a built-in steel spring.

[0007] Preferably, the vibration damping and sound insulation pad is made of polyurethane with a thickness of 5mm to 20mm, and is used to form a sound barrier.

[0008] Preferably, the edge of the vibration damping and sound insulation pad extends upward to the top surface of the decorative floor layer to cover the wall surface.

[0009] Preferably, the diaphragm is a PE membrane.

[0010] Preferably, the thickness of the cement mortar layer is 20 mm.

[0011] Preferably, the wall corresponding to the anti-resonance sound insulation floor slab is a cement or lightweight wall, and a skirting board is provided at the bottom of the wall, which is higher than the vibration damping and sound insulation pad on the wall.

[0012] The beneficial effects of this utility model are: 1. This utility model has a simple structure, is easy to construct, and has strong applicability. It can be quickly assembled and constructed. The floor slab structure of this utility model effectively reduces vibration and noise, reduces the damage caused by vibration and noise to the floor slab, and at the same time reduces the fatigue damage of dynamic loads to the floor materials. It solves the technical problem of floor slab resonance caused by dynamic loads and improves the service life of the floor slab. 2. The air spring bladder is a sealed, foldable rubber container filled with compressed inert gas. It utilizes the compressibility of the gas to achieve its elastic effect, exhibiting ideal non-linear elastic characteristics. This invention employs a special arrangement structure for the air spring bladder, effectively converting the localized dynamic load of the upper floor slab into a uniformly distributed static load, which is then transferred to the concrete floor slab. The cement mortar layer serves as a leveling, protective, vibration-damping, and sound-insulating pad. This pad acts as the first line of defense for sound insulation and vibration reduction, weakening vibration and noise. The entire floor structure of this invention has a clear division of labor among its layers, a clear force transmission path, and is used as a whole. This eliminates safety hazards and extends the service life of areas prone to resonance. Attached Figure Description

The spacing between adjacent air springs 2 is 20cm. Air springs adjacent to the corners of the walls... Airbag 2 is installed flush with the corner of the wall. The bottom of the air spring airbag 2 is bonded to the concrete floor slab 1, and the top of the air spring airbag 2 is bonded to the vibration damping and sound insulation pad 3. The edge of the vibration damping and sound insulation pad 3 covers the corner of the wall, and the edge of the vibration damping and sound insulation pad 3 extends upward by 20cm to cover the wall surface. The vibration damping and sound insulation pad 3 is made of polyurethane vibration damping and sound insulation pad with a thickness of 10mm. The diaphragm 4 is a PE film, and the cement mortar layer 5 has a thickness of 20mm. The wall 7 corresponding to the anti-resonance sound insulation floor slab is a cement wall. A skirting board 8 is provided at the bottom of the wall surface, and the skirting board 8 is higher than the vibration damping and sound insulation pad 3 on the wall surface.

[0017] The working principle and process of this utility model: The anti-resonance sound insulation floor slab is constructed according to the following procedure: I. Grassroots Handling and Preparation 1. Base surface cleaning: Remove dust, oil stains, loose particles and protrusions (such as steel bar ends and wooden stakes) from the surface of the concrete floor slab 1; check for hollow areas in the base layer, remove the hollow layer, repair and level it to ensure surface flatness; 2. Measurement and layout: Set the elevation line of the finished building surface, mark the two points of the air spring airbag (arranged in rows and columns, with a spacing of 20cm~50cm) and the position of the corner edge.

[0018] II. Air Spring Airbag Installation Arrange the air spring airbags 2 according to the marked points. The top of the airbag is bonded to the vibration damping and sound insulation pad 3 with strong adhesive, and the bottom of the airbag is bonded to the concrete floor slab 1 with strong adhesive. After installation, check the airbag's sealing performance to avoid air leakage.
