Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabricated floor, in particular to a fabricated sound insulation floor and an assembling process. BACKGROUND

[0002] With the rapid development of modern building technology and the increasing demand for living and working environment quality, the performance of building floor has become one of the key concerns in building design and construction. Among many performance indicators, sound insulation performance is particularly critical, as it directly affects the acoustic environment of the building interior space and the comfort of users' life and work.

[0003] In the construction of traditional building floor, concrete solid slab or simple composite structure is usually used. These traditional floor structures have many limitations in sound insulation. On the one hand, although the mass density of concrete solid slab is large, it can block the propagation of some sound to a certain extent, but the sound insulation effect for medium and high frequency sound is not ideal. Due to its relatively dense internal structure, sound waves lack effective sound absorption and sound elimination mechanism when propagating in it, leading to the problem of noise interference caused by direct conduction of sound through the floor to the adjacent floor. On the other hand, simple composite structure floor often fails to fully utilize the acoustic properties of each material due to unreasonable material selection and combination, and has obvious deficiencies in the synergistic optimization of sound absorption and sound insulation performance. SUMMARY

[0004] The present application relates to a fabricated sound insulation floor, which solves the problems of lack of effective sound absorption and elimination mechanism in traditional building floor and inability to fully utilize the acoustic properties of materials.

[0005] The present application provides a fabricated sound insulation floor, which specifically comprises: a concrete solid main plate, a steel bar layer composed of stress steel bars and distribution steel bars laid inside the concrete solid main plate, an inner plate layer provided on the upper side and the lower side of the concrete solid main plate, the inner plate layer adopts a wooden plate structure, a plurality of sound absorption matching openings are uniformly distributed on the top surface of the inner plate layer and penetrate the bottom surface of the inner plate layer, the sound absorption matching openings have a hexagonal structure; one sound absorption matching piece is placed in each complete sound absorption matching opening, and the sound absorption matching piece is made of glass fiber cotton material.

[0006] Further, the sound absorption matching piece has a spherical structure, and the diameter of the sound absorption matching piece is smaller than the structural size of the sound absorption matching opening.

[0007] Further, the concrete solid main plate and the two inner plate layers are connected by a group of sound absorption layers, and the sound absorption layers are made of mineral wool material.

[0008] Further, the sound absorption layer completely seals and covers the contact end surfaces of the concrete solid main plate and the inner plate layer.

[0009] Further, the top end face of the built-in plate layer on the upper side and the bottom end face of the built-in plate layer on the lower side are fixedly bonded with a set of reinforcing layers made of carbon fiber material.

[0010] Further, the reinforcing layers completely seal and cover the contact end face of the built-in plate layer.

[0011] The application provides an assembled sound insulation floor and an assembling process, and has the following beneficial effects:

[0012] The application forms a wooden honeycomb plate structure through the cooperation of the built-in plate layer and the sound absorption cooperation opening, which is beneficial to the sound wave entering the small pores in the wooden material, vibrating the air in the pores, and the air rubbing against the cell walls of the wood to consume sound energy when the sound wave enters, and the sound absorption cooperation opening in the hexagonal structure can make the sound reflect multiple times, and part of the sound energy is absorbed or changed in direction each time, and each sound absorption cooperation opening can be regarded as a small resonance cavity, and when the external sound frequency is close to the natural frequency, resonance absorption of sound energy occurs, thereby realizing sound absorption effect and assisting the floor to realize sound insulation function.

[0013] The application places a spherical sound absorption cooperation piece made of glass fiber cotton material in each complete sound absorption cooperation opening, and each complete sound absorption cooperation opening is in a sealed environment, so when the sound wave enters, it will reflect and scatter multiple times on the wall surface of the sound absorption cooperation opening and the surface of the sound absorption cooperation piece, increasing the number and complexity of the pores of the overall structure, making the sound wave propagation path more complex, increasing the interaction opportunity with the material, and more sound energy is consumed in the reflection and scattering process, thereby improving the sound absorption effect and further assisting the floor to realize sound insulation function.

[0014] The sound absorption layer of the application is made of mineral wool material, which realizes sound absorption cooperation with the built-in plate layer and the sound absorption cooperation piece, the high porosity of the mineral wool fiber provides a large number of channels for the sound wave to enter, can effectively absorb sound in a wide frequency range, and through the loose porous structure, the air molecules vibrate and rub against the mineral wool fiber wall after the sound wave enters the pores, converting the sound energy into heat energy to consume sound energy, achieving the effect of sound absorption, and further assisting the floor to realize sound insulation function.
