[0006] The technical scheme of the present application is as follows: a prefabricated soundproof decorative wall panel, comprising: a plurality of wall panel bodies, the plurality of wall panel bodies are connected by connecting pieces and assembled on a building outer wall; a thermal inertia sound insulation cavity is arranged in the wall panel body, a closed thermal inertia sound insulation chamber is arranged in the thermal inertia sound insulation cavity, a sealed liquid damping medium is arranged in the thermal inertia sound insulation chamber, the volume of the liquid damping medium is smaller than the volume of the thermal inertia sound insulation chamber, so that the liquid damping medium can absorb sound waves and compensate for the heat of the wall panel body.

[0007] By adopting the above scheme, by setting the heat inertia sound insulation cavity inside the wallboard body, and setting the liquid damping medium inside the heat inertia sound insulation cavity, because the volume of the heat inertia sound insulation cavity is greater than the volume of the liquid damping medium, the liquid damping medium utilizes the viscous damping characteristics of itself to generate a reverse vibration against low-frequency sound waves, significantly improves the low-frequency sound insulation amount, and further improves the sound insulation effect, At the same time, by using the good specific heat capacity of the liquid damping medium, the temperature change of the wallboard body itself can be compensated, the heat passing through the wallboard body to the building outer wall can be reduced, the heat can be buffered, and the heat balance can be achieved.

[0008] In an embodiment of the present application, the wallboard body comprises: A damping layer for blocking external temperature from being transmitted to a side close to the building outer wall; Two sound insulation boards are arranged on the two side surfaces of the damping layer.

[0009] By adopting the above technical scheme, the damping layer for heat insulation and the sound insulation board capable of absorbing sound wave vibration to achieve sound insulation effect are compounded with each other, so that the sound insulation and heat insulation performance of the wallboard body can be improved.

[0010] In an embodiment of the present application, the shape of the heat inertia sound insulation cavity is consistent with the shape of the heat inertia sound insulation cavity, and a deformation gap is formed above the liquid surface of the liquid damping medium inside the heat inertia sound insulation cavity.

[0011] By adopting the above scheme, by setting the closed heat inertia sound insulation cavity inside the heat inertia sound insulation cavity, the liquid damping medium is arranged inside the heat inertia sound insulation cavity, and a deformation gap is reserved inside it. When a small amount of sound wave penetrates the sound insulation layer close to the outside, especially for the low-frequency sound wave vibration, the internal liquid damping medium can be caused to vibrate, and then the energy in the sound wave can be converted into kinetic energy and thermal energy generated by the vibration of the liquid damping medium, so as to achieve the purpose of further sound insulation; In addition, when the heat penetrates the damping layer, the liquid damping medium can utilize the good specific heat capacity characteristics of itself at high temperature or low temperature to further balance the penetrated heat, so that the heat can pass through the entire wallboard body more slowly, improve the heat inertia of the device, and make the wallboard body have the effect of warm in winter and cool in summer.

[0012] In an embodiment of the present application, the heat inertia sound insulation cavity is a rectangular cavity, and is arranged inside the damping layer close to the building outer wall. The heat inertia sound insulation cavity extends along the length direction of the damping layer.

[0013] By adopting the above scheme, the heat-inert sound insulation cavity is arranged as a rectangular cavity, heat conduction is conducted through two sides close to the sound insulation layer with relatively large area, and the liquid damping medium inside can be compensated and balanced according to temperature change.

[0014] In one of the embodiments of the present application, the heat-inert sound insulation cavity is a strip-shaped cavity, the heat-inert sound insulation cavity extends along the length direction of the damping layer and is arranged at one side close to the building outer wall inside the damping layer, a plurality of heat-inert sound insulation cavities are arranged in the width direction of the wallboard body, and the heat-inert sound insulation layer is formed.

[0015] By adopting the above scheme, the heat-inert sound insulation cavity is arranged as a rectangular cavity, heat conduction is conducted through two sides close to the sound insulation layer with relatively large area, and the liquid damping medium inside can be compensated and balanced according to temperature change.

[0016] In one of the embodiments of the present application, the heat-inert sound insulation layer is arranged in two layers and is arranged in the thickness direction of the damping layer, and the heat-inert sound insulation cavities in the two layers of the heat-inert sound insulation layer are arranged alternately.

[0017] By adopting the above scheme, the heat-inert sound insulation layer is arranged in two layers, the heat-inert sound insulation cavities in the two layers are arranged alternately, sound waves can pass through the gap in the first layer of the heat-inert sound insulation layer, the sound waves fall on the surface of the heat-inert sound insulation cavity, thereby prolonging the transmission path of the sound waves, and the high-frequency sound waves with short wavelength and poor diffraction ability can be further blocked by the device. In addition, the double-layer heat-inert sound insulation layer can form a skeleton with bending moment resistance, so that the device can further transmit and disperse stress and improve structural strength.

[0018] In one of the embodiments of the present application, the heat-inert sound insulation cavity is a strip-shaped cavity, the heat-inert sound insulation cavity extends along the length direction of the damping layer and is arranged at one side close to the building outer wall inside the damping layer, a plurality of heat-inert sound insulation cavities are arranged in the width direction of the wallboard body, and the heat-inert sound insulation layer is formed. The heat-inert sound insulation cavity is a strip-shaped cavity, the heat-inert sound insulation cavity extends along the length direction of the damping layer and is arranged at one side close to the building outer wall inside the damping layer, a plurality of heat-inert sound insulation cavities are arranged in the width direction of the wallboard body, and the heat-inert sound insulation layer is formed.

[0019] By adopting the above scheme, when the outside low temperature can penetrate the damping layer and cause the liquid damping medium to freeze in cold weather, the elastic block can deform according to the volume expansion when the liquid damping medium freezes and fills the entire deformation gap, thereby avoiding the expansion caused by the freezing of the liquid damping medium and preventing the wallboard main body from being cracked; In addition, by arranging the flow guide cylinder on the elastic block, when there is a temperature difference between the heat on one side of the thermal inertia sound insulation warehouse close to the wall and the heat on the other side, the temperature difference can drive the liquid damping medium inside to form microcirculation inside and outside the flow guide cylinder, utilize the heat absorption characteristics of the liquid damping medium to drive the liquid damping medium to circulate, and in the process of circulation of the liquid damping medium, the liquid damping medium can pass through the inner spiral flow guide strip on the inner wall of the flow guide cylinder, and then form a local vortex, so that the sound wave can be further scattered and consumed when reaching the liquid damping medium with the vortex.

[0020] In one embodiment of the present application, the connecting piece comprises: The connecting strip is provided with a T-shaped clamping tenon on both sides. The elastic layer is wrapped outside the connecting strip, and the T-shaped clamping tenon is in interference fit with the strip-shaped mortise.

[0021] By adopting the above scheme, when it is necessary to splice two adjacent wallboard main bodies together, the split connecting piece can avoid the trouble of separately designing two different types of closing strips in the conventional mortise and tenon structure to separately close the side edges of the wallboard main bodies with different shapes. In addition, the interference fit between the T-shaped clamping tenon and the strip-shaped mortise enables the two adjacent wallboard main bodies to be tightly pressed together, and the elastic layer fills the gap of the strip-shaped mortise between the two adjacent wallboard main bodies, thereby improving the ease of assembly and the heat and sound insulation of the device.

[0022] In one embodiment of the present application, the damping layer is provided with a plurality of semispherical recesses on both sides, and the sound insulation board is provided with a plurality of semispherical protrusions on the surface close to the damping layer.

[0024] The second object of the present application is to provide a prefabricated sound insulation decorative wall.

[0025] The technical scheme is as follows: a prefabricated sound insulation decorative wall comprises a prefabricated sound insulation decorative wallboard and a mounting rail, one side of the mounting rail is provided with a sealing fastening strip matched with the shape of the strip-shaped tenon groove, the mounting rail is connected and fixed with the prefabricated sound insulation decorative wallboard through the sealing fastening strip, and the other side of the mounting rail is provided with a mounting strip, and the mounting rail is fixed and assembled on the building outer wall through the mounting strip. The sealing fastening strip is externally fixedly connected with a flexible buffer layer, and the sealing fastening strip is in interference fit with the strip-shaped tenon groove through the flexible buffer layer.

[0026] By adopting the above scheme, since the external shape of each prefabricated sound insulation decorative wallboard constituting the sound insulation decorative wall is consistent, the design cost in assembling according to different building outer walls is reduced, and meanwhile, when mounting, the sound insulation decorative wall which has been spliced is only needed to be edge-sealed by using one type of mounting rail, so that the mounting difficulty is reduced, and the trouble of separately designing the closing strip according to the shapes of different side edges of the single wallboard is avoided. In addition, by arranging the flexible buffer layer outside the sealing fastening strip, the flexible buffer layer can fill the gap between the strip-shaped tenon groove and the sealing fastening strip, block heat, and absorb sound wave vibration, so as to further improve the heat insulation performance and sound insulation performance of the wall body and the building outer wall at the connecting position.

[0027] In summary, the present application has at least one beneficial technical effect: by arranging the liquid damping medium inside the wallboard body, the heat capacity of the liquid damping medium is utilized to compensate for the temperature change of the wallboard body, realize the heat balance, and since the volume of the thermal inertia sound insulation cavity is greater than that of the liquid damping medium, the liquid damping medium can absorb external sound wave vibration, thereby further improving the sound insulation effect.

[0028] By arranging the split type connecting piece, the two separate wallboard bodies are connected, the gap generated when the two wallboard bodies are connected is filled by using the elastic force generated when the elastic layer is compressed, the heat insulation performance and sound insulation performance of the wallboard body when connected are improved, and meanwhile, the side edge shape of each wallboard body is consistent, the mortise and tenon connection structure between the conventional wallboards is avoided, the closing strip needs to be separately designed for different shapes of side edges to avoid the trouble of edge sealing, and the difficulty and cost of subsequent wall surface installation are reduced.

[0029] By setting multiple strip-shaped thermal inertia sound insulation cavities, and setting liquid damping medium inside each thermal inertia sound insulation cavity, heat compensation balance can be achieved by using the specific heat capacity of the liquid damping medium itself, while ensuring that the liquid damping medium can vibrate inside each thermal inertia sound insulation cavity and absorb sound wave vibration, thereby improving the sound insulation effect, and the overall volume of the thermal inertia sound insulation cavity can be effectively reduced, thereby reducing the hollow area inside the wallboard main body, and further ensuring the overall structural strength of the wallboard main body.

[0030] By setting a double-layer thermal inertia sound insulation layer, the good absorption capacity of the thermal inertia sound insulation cavity for low-frequency sound waves is utilized, and the thermal inertia sound insulation cavity is set as two layers staggered with each other, so that the entire wallboard not only further improves the bending resistance, but also ensures the enhanced absorption capacity of the device for low-frequency sound waves, and improves the blocking capacity of the device for high-frequency sound waves, so that the sound insulation capacity of the device is further improved.

[0031] By setting a flow guide cylinder on the elastic block, the characteristics of the liquid damping medium absorbing heat are utilized, and the liquid damping medium is driven to circulate by the temperature difference on both sides of the thermal inertia sound insulation cavity, so that the liquid damping medium can pass through the inner helical flow guide strips on the inner wall of the flow guide cylinder and form local vortexes during circulation, further scattering and consuming sound waves that penetrate into the thermal inertia sound insulation cavity, thereby improving the sound insulation effect.
