Description

Multi-story floor

The invention relates to a floor, especially a multi-layer floor with sound insulation/sound-absorbing function.

With the development of urbanization, the population of cities has also increased rapidly. With limited land, people’s housing types have also changed from single-family houses in the early days to collective housing. Because of the innumerable families living in the collective housing, it is extremely susceptible to noise. Therefore, the sound insulation of the housing will profoundly affect the quality of life of the residents. Normally, the noise from the upper floor, such as footsteps, is most easily felt between the lower floors. It can be seen that the floor floor will be closely related to the prevention and control of noise. In other words, the sound insulation of residential floor floors is one of the topics worthy of research at present.

In view of this, the present invention proposes a multi-layer floor, which can effectively reduce the transmission of sound through the special configuration of the multi-layer structure. The multi-layer floor of the present invention includes: a floor slab layer, a buffer layer, a sound prevention layer, a metal mesh layer and an enclosed layer. The buffer layer is arranged on the floor layer; the sound prevention layer is arranged on the buffer layer; the enclosed layer is arranged on the sound prevention layer, and the enclosed layer includes a metal mesh layer.

In summary, the sound prevention layer of the present invention is arranged on the buffer layer, so when the sound waves in the air want to pass through the multi-floor floor and transmit to the lower floor, the sound prevention layer in the multi-floor floor can first isolate or absorb most of it The sound waves that have not been eliminated and the resonance generated by the sound waves on the multi-storey floor can be eliminated by the buffer layer, thereby effectively reducing the transmission of noise.

In one embodiment, the sealing layer 50 and the metal mesh layer 40 are combined through reinforced concrete (RC). For example, the metal mesh layer 40 is first placed on the sound prevention layer 30, and then the metal mesh layer Concrete is poured between and around the grids of 40, and the closed layer 50 can be formed after the concrete is air-dried, but it is not limited to this. Thereby, the sound prevention layer 30 and the buffer layer 20 can be sealed between the enclosed layer 50 and the floor layer 10 to protect and fix the metal mesh layer 40, the sound prevention layer 30 and the buffer layer 20. In one embodiment, the sealing layer 50 has a sealing layer bottom surface 50b in contact with the sound preventing layer 30 and a sealing layer top surface 50a opposite to the sealing layer bottom surface 50b, wherein the sealing layer bottom surface 50b and the sealing layer top surface 50a are between The shortest distance can be defined as a sealing layer thickness t5, that is, the sealing layer 50 has a sealing layer thickness t5 in the vertical direction (Z direction).

In other words, the thickness of each layer t1~t5 can be regarded as one of the features of the present invention.

In addition, after the sound prevention layer 30 and the buffer layer 20 are sealed between the closed layer 50 and the floor layer 10, the decoration surface material 60 can be further disposed on the top surface 50a of the closed layer. In an embodiment, the decoration surface material 60 may be the outermost structure of various floors, such as tiles, wooden boards, etc., and is not limited thereto. The decoration surface material 60 may have a decoration surface material top surface 60a and a decoration surface material bottom surface 60b, wherein the decoration surface material top surface 60a and the decoration surface material bottom surface 60b may be of different materials. Thereby, the multi-layer floor 1 of the first embodiment can be realized.

In addition, the multi-story floor 1 of the present invention may also have different implementation aspects. Please refer to Figure 3 and Figure 4 at the same time. FIG. 3 is a schematic diagram of the stacked structure of the multi-layer floor 1 according to the second embodiment of the present invention, and FIG. 4 is an exploded view of the structure of the multi-layer floor 1 according to the second embodiment of the present invention.

In addition, the waterproof layer 70 has a waterproof layer top surface 70a in contact with the sealing layer 50 and a waterproof layer bottom surface 70b in contact with the sound prevention layer 30, wherein the shortest distance between the waterproof layer top surface 70a and the waterproof layer bottom surface 70b is defined as A waterproof layer thickness t7, that is, the waterproof layer 70 has a waterproof layer thickness t7 in the vertical direction (Z direction). In an embodiment, the thickness t7 of the waterproof layer is not greater than 1 cm. In one embodiment, the thickness t7 of the waterproof layer is substantially 1 mm.

Since the waterproof layer 70 is disposed on the sound prevention layer 30, when the floor board is wetted, the waterproof layer 70 can first absorb moisture to prevent the sound prevention layer 30 from getting damp due to the penetration of moisture. Thereby, the multi-story floor 1 can have the functions of waterproofing and sound insulation/sound absorption.

In addition, the multi-layer floor 1 of the present invention can still have different implementation aspects. Please refer to Figure 5 and Figure 6 at the same time. FIG. 5 is a schematic diagram of the stacked structure of the multi-layer floor 1 according to the third embodiment of the present invention, and FIG. 6 is an exploded view of the structure of the multi-layer floor 1 according to the third embodiment of the present invention.

As shown in Figures 5 and 6, the multi-layer floor 1 of the third embodiment also includes a floor layer 10, a buffer layer 20, a sound prevention layer 30, a metal mesh layer 40, and a closed layer 50, and the closed layer 50 can be further A decoration surface material 60 is provided; the characteristic of the third embodiment is that the buffer layer 20 may include a plurality of support members 80. Since the floor layer 10, the buffer layer 20, the sound prevention layer 30, the metal mesh layer 40 and the sealing layer 50 of the third embodiment can be applied to the description of the first embodiment, they will not be described in detail.

In one embodiment, the support member 80 is a columnar structure, and has a support surface 81 and a columnar body 82, wherein the support surface 81 extends on the XY plane and is viewed along the Z direction, the support surface 81 It is wider than the columnar body 82.

The columnar body 82 is used to be disposed at the bottom of the buffer layer 20 to fix the support member 80. The fixing method can be, for example, a part of the columnar body 82 penetrates into the buffer layer 20, or a part of the columnar body 82 can also be used. It penetrates the entire buffer layer 20 and then penetrates deeper into the floor layer 10 at the bottom. Therefore, the overall length of the support member 80 in the Z direction can be greater than the buffer layer thickness t2 (marked in FIG. 1); the invention is not limited to this. The supporting surface 81 is a surface extending on the XY plane for abutting against the sound prevention layer 30. The supporting surface 81 can have various shapes, preferably a symmetrical shape such as a circle, a square, an equilateral triangle, or an equilateral polygon, so that the entire surface can receive the force evenly when it is stressed. In addition, the material of the support 80 can be, for example, plastic, rubber, etc., and is not limited thereto. Preferably, the support member 80 itself can have a certain degree of elasticity, which is beneficial to produce a certain temporary deformation when subjected to a force to avoid breaking.

In an embodiment, the bubble buffering objects 22 in the buffer layer 20 are arranged at intervals, so the supporting members 80 may be arranged at the intervals. In another embodiment, the bubble buffering objects 22 in the buffer layer 20 are closely arranged, so the support member 80 can be directly disposed at a part of the bubble buffering object 22 and penetrate the bubble buffering object 22; the invention is not limited to this.

A feature of the present invention is that the height of the supporting surface 81 in the Z direction is higher than the top of the bubble buffering object 22, that is, the supporting surface 81 is closer to the sound prevention layer 30 than the bubble buffering object 22 is. The advantage of this configuration is that when the multi-storey floor 1 is stressed, the supporting member 80 can be stressed first, thereby reducing the pressure on the bubble buffering object 22, which can extend the service life of the bubble buffering object 22.

It should be noted that the multi-layer floor 1 of the third embodiment can also be combined with the features of the second embodiment, that is, the multi-layer floor 1 can be provided with a support 80 and a waterproof layer 70 at the same time.

In this way, the present invention provides a multi-layer floor floor, each layer of which has different functions, and after special configuration, good sound insulation/sound absorption effects can be achieved. In addition, since the buffer layer is disposed under the sound prevention layer, the sound wave energy that the sound prevention layer cannot cut off can be eliminated in the buffer layer, so the sound insulation/sound absorption function can be further improved.

According to convention, reducing the noise by 18 decibels (dB) is a good sound insulation structure. According to the experimental results, the present invention can reduce the noise by 30dB, which shows that it can provide excellent sound insulation effect.
