[0003] The patent document with the publication number of CN216446271U discloses a new type of floating floor, which includes a reinforced concrete structure layer, a sound insulation layer is laid on the top surface of the reinforced concrete structure layer, and a reinforced concrete protection layer is arranged on the top surface of the sound insulation layer; the characteristics are: the sound insulation layer includes a shock pad made of rubber and plastic materials, the shock pad includes a plate body, and round pier-shaped inverted convex platforms are integrally formed in an array on the bottom surface of the plate body; blind holes are opened on the bottom surface of the inverted convex platform; upper clamping edges and lower clamping edges that cooperate with each other are arranged opposite to the edge of the plate body.

[0004] The sound insulation layer adopted by the above device is made of rubber and plastic materials. As is well known, although rubber and plastic materials have a lasting elastic recovery force and good shock absorption, the rubber and plastic materials themselves are relatively soft. During and after the laying process, due to the insufficient physical and mechanical strength of the sound insulation layer, the upper concrete leveling layer and the decorative board layer above are prone to local micro-collapse under high pressure or high-intensity vibration, thus damaging the upper structure of the floor, and the support and use quality of the floor paving surface cannot be effectively guaranteed; therefore, it is necessary to improve the existing floating floor.

[0006] Therefore, the purpose of the utility model is to provide a floating sound insulation floor to solve the problems in the prior art that the existing floating floor has low mechanical strength and is prone to local micro-collapse under high pressure or high-intensity vibration, thus damaging the upper structure of the floor, and the support and use quality of the floor paving surface cannot be effectively guaranteed.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A floating sound-insulating floor slab, which includes a concrete structure layer, a sound-insulating board, and a concrete leveling layer. The sound-insulating board is attached to the upper layer of the concrete structure layer, and the concrete leveling layer is laid on the upper layer of the sound-insulating board.

[0008] The sound-insulating board is a splicing structure on both sides, which are respectively a first cushion plate at the lower layer and a second cushion plate fitted and installed on the upper part of the first cushion plate. The opposite surfaces of the first cushion plate and the second cushion plate have a number of sound-absorbing holes extending into the first cushion plate and the second cushion plate, and the sound-absorbing holes are evenly distributed on the unfolded surface of the board body of the sound-insulating board.

[0009] As a preferred scheme of a floating sound-insulating floor slab according to the present utility model, among them, positive convex platforms are evenly distributed on the upper part of the first cushion plate. The top surface of the positive convex platform has a sound-absorbing hole one extending vertically into the positive convex platform. The lower part of the second cushion plate is evenly distributed with inverted convex platforms matching and fitting with the positive convex platforms. The bottom surface of the inverted convex platform has a sound-absorbing hole two extending vertically into the inverted convex platform.

[0010] As a preferred scheme of a floating sound-insulating floor slab according to the present utility model, among them, the inverted convex platform and the positive convex platform are trapezoidal structures with the same inclined surface angle, and the distances between adjacent inverted convex platforms and between adjacent positive convex platforms are the same.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the floating sound insulation floor, by adopting a hard sound insulation board with sound absorption effect, not only has good mechanical strength, but also the upper and lower pads are in a fixed integrated state after being overlapped, so that the sound insulation board and the entire upper paving surface of the floor can be kept solid; in addition, when the floor vibrates, the shock wave and noise will be directly transmitted to the first pad and the second pad through the ground decoration layer and the concrete leveling layer. The noise generated in this process will be directly absorbed by the sound insulation board or enter the sound absorption hole 1, the sound absorption hole 2 and the echo chamber. After frequent refraction and reflection, the noise resonance and decibel are greatly reduced in a short time, and the hollow layer reserved by the echo chamber also enables the sound insulation board to form a certain vertical avoidance buffer force, which further improves the noise reduction effect while reducing shock.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Figures 1 - 3 The following is a schematic diagram of the entire structure of a floating sound insulation floor of the utility model. Figures 1 - 3A floating sound insulation floor slab in this embodiment includes a concrete structure layer 100, a sound insulation board 200 and a concrete leveling layer 300, wherein the sound insulation board 200 is attached to the upper layer of the concrete structure layer 100 and the concrete leveling layer 300 is laid on the upper layer of the sound insulation board 200; the sound insulation board 200 is a two-side splicing structure, which includes a first pad 210 at the lower layer and a second pad 220 embedded and installed on the upper part of the first pad 210, and the opposing surfaces of the first pad 210 and the second pad 220 have a plurality of sound absorbing holes extending into the inside of the first pad 210 and the second pad 220, and the sound absorbing holes are evenly distributed on the plate body unfolding surface of the sound insulation board 200.

[0023] Positive bosses 211 are evenly distributed on the upper part of the first pad 210, and the top surface of the positive boss 211 has a sound-absorbing hole 1 2111 extending vertically into the inside of the positive boss 211; inverted bosses 221 matching and engaging with the positive boss 211 are evenly distributed on the lower part of the second pad 220, and the bottom surface of the inverted boss 221 has a sound-absorbing hole 22111 extending vertically into the inside of the inverted boss 221; the inverted boss 221 and the positive boss 211 are trapezoidal structures with the same inclined surface angle, and the spacing between adjacent inverted bosses 221 and adjacent positive bosses 211 is the same. Here, the sound insulation board 200 can be made of relatively hard materials such as sound-absorbing wood boards and mineral wool, which not only has a good sound absorption effect, but also has good mechanical strength. At the same time, since the first pad 210 and the second pad 220 are in a fixed integrated structure after being overlapped, the sound insulation board 200 and the entire upper paving surface of the floor can be kept solid, and the use effect is effectively guaranteed; the vertical height of the positive boss 211 is smaller than the vertical height of the inverted boss 221, and an echo chamber 230 is provided between the top of the positive boss 211 and the adjacent inverted boss 221. In this embodiment, when the floor vibrates, the shock wave and noise will be directly transmitted to the first pad 210 and the second pad 200 through the ground decoration layer 500 and the concrete leveling layer 300. The noise generated in this process will be directly sucked into the sound insulation board 200 or enter the sound absorption hole 1 2111, the sound absorption hole 2211 and the echo chamber 230. After frequent refraction and reflection, the noise resonance and decibel are greatly reduced in a short time. In addition, the hollow layer reserved by the echo chamber 230 also enables the sound insulation board 200 to form a certain vertical avoidance buffer force, which further improves the noise reduction effect while reducing shock.

[0024] Furthermore, there is an adhesive mortar layer 400 between the sound insulation board 200 and the concrete structure layer 100. The coated adhesive mortar layer 400 makes the paving between the sound insulation board 200 and the concrete structure layer 100 more stable, and the adhesive mortar layer 400 also has a certain waterproof effect.

[0025] Furthermore, a floor decoration layer 500 is provided above the concrete leveling layer 300, and the top height of the floor decoration layer 500 is higher than the connection height between the sound insulation board 200 and the wall skirting board. It can be understood that the concrete leveling layer 300 is mainly used to level the top surface of the sound insulation board 200 and provide covering protection, which is beneficial to the smooth paving of the floor decoration layer 500. The floor decoration layer 500 can be a floor, ceramic tiles, epoxy floor, etc.

[0026] In summary, for a floating sound insulation floor slab according to this embodiment, when vibrations occur on the floor surface, shock waves and noise will be directly transmitted to the first cushion plate 210 and the second cushion plate 200 through the floor decoration layer 500 and the concrete leveling layer 300. During this process, the noise generated will be directly absorbed by the sound insulation board 200 or enter the first sound absorption holes 2111, the second sound absorption holes 2211, and the echo chamber 230. After frequent refraction and reflection, the noise resonance and decibels are significantly reduced in a short time. Moreover, the hollow layer reserved in the echo chamber 230 also enables the sound insulation board 200 to form a certain vertical avoidance buffer force, further improving the noise reduction effect while reducing vibration.

[0027] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
