Technical Field
[0001] The utility model belongs to the technical field of scale models, and in particular relates to a scale model for testing the sound insulation performance of building structures. Background Art
[0002] In recent years, my country's real estate market has experienced rapid growth, but it has also encountered numerous challenges, such as residential sound insulation. Numerous solutions have been implemented, including the use of soundproof windows on exterior windows, heavy-duty or high-sound-insulating structures for partition walls, and the installation of vibration-damping pads on floor slabs. These measures have objectively reduced the impact of household noise and achieved a certain degree of sound insulation and noise reduction. However, acoustic design differs from visual design. While visible design can be intuitively perceived, acoustic design struggles to immediately convey its effects. This explains why many people only discover various noise issues after living in their homes for a while, complaining to the property management, and then resolving the noise issues at a significantly higher cost.

The decibel of the sound emitted by the first detection piece hitting the sound insulation material after the sound insulation material is added, and the decibel of the sound emitted by the first detection piece hitting the ordinary partition after the ordinary partition is added are compared to judge the sound insulation effect.
[0004] However, the detection device can only detect the sound insulation effect of the floor between the upper and lower floors, and cannot fully and intuitively display the sound insulation effect of the building, such as the sound insulation effect between the walls of the same floor, the sound insulation effect of the noise emitted by outdoor cars, motorcycles and other equipment, etc. Users cannot have a direct experience of the sound insulation effect of the building before moving in.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.
[0029] Please see Figures 1 to 4 A scale model for testing the sound insulation performance of a building structure includes a scale model body 100 and a movable sound-generating member 200 disposed near the scale model body 100. The scale model body 100 is 1700 mm long, 1700 mm wide, and 1900 mm high, and can be placed in an exhibition hall. The scale model body 100 is small in size and convenient for display to users. The movable sound-generating member 200 can move near the scale model body 100 and emit noise.
[0030] The scale body 100 includes: a first chamber 110, wherein the first chamber 110 is provided with a detachable first soundproof glass 111, and soundproof glass with different sound insulation effects can be installed on the surface of the first chamber 110; a first detection member 112 is suspended from the top of the first chamber 110, and a first floor 113 and a first noise detection member 114 are arranged below the first detection member 112, and the first floor 113 is laid flat on the upper end surface of the first noise detection member 114; the first floor 113 is a floor slab used to simulate a building, and the first floor 113 is a floor slab with sound insulation material. The first detection member 112 is lifted and can be suspended to any height of the first chamber 110, up to the top of the first chamber 110; the first detection member 112 is suspended to a preset height in the first chamber 110, and the first detection member 112 is controlled to fall from mid-air and hit the first floor 113, and the first floor 113 collides with the first detection member 112. The collision produces a sound, and the first noise detection component 114 detects the decibel of the sound (the first noise detection component 114 is an existing noise detection device) and displays the decibel of the sound. According to the same method, it can be measured multiple times and the average value is taken to obtain the sound insulation effect of the first floor 113. Then the first floor 113 is replaced with an ordinary floor, and according to the same method, the decibel of several groups of sounds after adding ordinary partitions are obtained and the average value is taken. The first detection component 112 is dropped on the first floor 113 to simulate the sound of a heavy object on the upper floor falling and hitting the floor. The sound felt by the users on the next floor is used to judge the sound insulation effect brought by using the first floor 113. At the same time, the first detection component 112 is suspended to the highest height (that is, suspended to the top of the first chamber 110) and dropped to the ground to simulate the sound of a heavy object thrown up on the upper floor falling to the ground. The sound felt by the users on the next floor is used to judge the sound insulation effect brought by using the first floor.
[0031] A second chamber 120 is provided with a first partition wall 115 between the second chamber 120 and the first chamber 110. The second chamber 120 and the first chamber 110 are adjacent to each other through the first partition wall 115. The second chamber 120 is provided with a removable second soundproof glass 121. A second partition wall 122, a second sound source 123 and a second noise detector 124 are provided in the second chamber 120. The second partition wall 122 separates the second chamber 120. The second sound source 123 and the second noise detector 124 are provided on both sides of the second partition wall 122, and the second noise detector 124 is provided on the side close to the first partition wall 115. The second partition wall 122 is a partition wall on the same floor of a simulated building (such as a partition wall between bedrooms). At the same time, the second partition wall 122 is a partition wall with sound insulation material. Sound is emitted by the second sound source 123 (the second sound source 123 is an existing sound-emitting device, and the sound emitted can be high-decibel noise, loud talking, or normal communication sound). After the sound passes through the second partition wall 122 and is soundproofed by the second partition wall 122, the second noise detection component 124 detects the decibel of the sound (the second noise detection component 124 is an existing noise detection device) and displays the decibel of the sound. The same sound is pronounced multiple times and an average value is taken; the different decibels of the sound emitted by the second sound source 123 are adjusted, and the second noise detection component 124 detects the decibel of the sound and an average value is taken.
[0032] The movable sound-emitting member 200 moves near the scale body 100 to simulate the movement of a car near a building. Simultaneously, the movable sound-emitting member 200 emits a sound and adjusts the decibel level to the same level as a car horn (i.e., 60-80 decibels) to simulate the sound of a car horn. The sound emitted by the movable sound-emitting member 200 passes through the second soundproof glass 121 , which simulates the soundproof glass of a building, and the second noise detector 124 detects the decibel level of the sound.
[0033] The effect achieved:
[0034] The first detection member 112 is dropped onto the first floor slab 113, simulating the sound felt by users on the next floor after a heavy object falls from the previous floor and hits the floor. This is used to determine the sound insulation effect provided by the use of the first floor slab 113 (i.e., the upper and lower floors). The second sound source 123 emits sound, which passes through the first partition wall 115 and is soundproofed by the second partition wall 122. The second noise detector 124 then detects the decibel level of the sound, simulating a partition wall between two rooms on the same floor and testing the sound insulation effect of the partition wall. The movable sounding member 200 moves near the scaled body 100 and emits sound, simulating the movement and noise of cars and other mobile devices near the building, and testing the sound insulation effect of the soundproof glass. By simulating a building with a scaled model, the sound insulation effect of the building can be intuitively displayed from different angles, allowing users to directly experience the building's sound insulation effect before moving in.
[0035] Specifically, a first lifting assembly is also provided at the top of the first chamber 110. The first lifting assembly suspends the first detection member 112. The first lifting assembly 118 includes a motor, a lifting rope, a magnet, and a reel. The motor is provided at the top of the first chamber 110. One end of the lifting rope is connected to the motor, and the magnet is connected to the other end of the lifting rope. The magnet is used to magnetically attract the first detection member 112. The reel is provided at the top of the first chamber 110. The lifting rope can be retracted by rotating the motor. The lifting rope is connected to the magnet, and the magnet is pulled up by the magnet, and the magnet magnetically attracts the first detection member 112. When the motor rotates forward, the lifting rope can be wound onto the reel as the motor rotates. When the motor rotates reversely, the lifting rope can be rotated along the reel and extended as the motor rotates. The first detection member 112 is an iron ball, and an arc-shaped groove is provided on the end face of one end of the magnet, and the arc-shaped groove can fit with the iron ball.
[0036] In one possible embodiment, see Figure 1The movable sound-emitting member 200 includes a track 210, a moving vehicle 220, and a fourth sound source 230. The track 210 is C-shaped and disposed near the scale body 100. The moving vehicle 220 is mounted on the track 210, and the fourth sound source 230 is mounted on the moving vehicle 220. The track 210 is configured to allow the moving vehicle 220 to move along it, preventing it from straying. Simultaneously, the moving vehicle 220 repeatedly moves along the track 210, driving the fourth sound source 230 to move, simulating the movement of multiple vehicles and their associated mobile equipment near a building. Furthermore, the longest travel distance of the moving vehicle 220 is on the side closest to the second soundproof glass 121, allowing the sound emitted by the fourth sound source 230 to pass directly through the second soundproof glass 121 without being affected by other obstacles.
[0037] In one possible embodiment, see Figure 1 A second knocking member 125 is also provided in the second chamber 120. The second knocking member 125 is provided on the second partition wall 122 and is located on one side of the second sound source 123. When it is necessary to simulate a user on the same floor knocking on the partition wall, the second knocking member 125 is installed on the second partition wall 122 and activated (the second knocking member 125 is an existing knocking device). The second knocking member 125 knocks on the second partition wall 122 with a preset force (the second sound source 123 does not emit any sound). The knocking sound of the second knocking member 125 passes through the second partition wall 122. After being soundproofed by the second partition wall 122, the second noise detector 124 detects the knocking sound of the second knocking member 125 and displays the decibel value. The second knocking member 125 is used to knock on the second partition wall 122 multiple times and an average value is taken. The second knocking member 125 knocks on the second partition wall 122, simulating a user on the same floor knocking on the partition wall, thereby visually demonstrating the sound insulation effect of the building and allowing users to have a direct experience of the building's sound insulation effect before moving in.
[0038] In a preferred embodiment, the second partition wall 122 is a 30mm-40mm thick steel plate. During the simulation process, the density and mass of the object are used to simulate the sound insulation performance. For example, a 30mm thick steel plate can be used to simulate the sound insulation performance of a 120mm thick concrete partition wall. A 1m2 30mm thick steel plate weighs 235.5kg, while a 1m2 120mm thick concrete wall weighs approximately 250kg. The two have similar masses: the density of the steel plate is 7860kg / m³, while the density of the concrete wall is 1950-2600kg / m³. However, the thickness of a 120mm concrete wall is three times that of a 30mm steel plate. Therefore, a 30mm thick steel plate can be used to simulate the sound insulation performance of a 120mm thick concrete partition wall. Similarly, a 40mm thick steel plate can be used to simulate the sound insulation performance of a 180mm thick concrete partition wall.
[0039] In a preferred embodiment, a noise reduction pad is attached to the second partition wall 122, and the sound insulation effect of the additional noise reduction pad can be simulated and tested.
[0040] In a preferred embodiment, the second partition wall 122 is tilted at an angle of 3°-7°. The tilted second partition wall 122 reduces sound reflections and superposition from the second sound source 123 when sound from the second sound source 123 propagates to the second partition wall 122, thereby minimizing the impact of standing sound waves on test results.
[0041] Specifically, the inclination angle of the second partition wall 122 is 3°.
[0042] Specifically, the inclination angle of the second partition wall 122 is 4°.
[0043] Specifically, the inclination angle of the second partition wall 122 is 5°.
[0044] Specifically, the second partition wall 122 has an inclination angle of 6°. When the second sound source 123 detects the sound, the second noise detector 124 shows that the sound reflection and sound superposition caused by the sound from the second sound source 123 are minimized when the inclination angle is 6°.
[0045] Specifically, the inclination angle of the second partition wall 122 is 7°.
[0046] In a possible embodiment, different floor slabs are clearly compared in the first chamber 110, and a detection device suitable for sound insulation materials with patent number CN202322661974.1 can be used to conduct experimental comparisons between the upper and lower floor slabs to determine the sound insulation effect.
[0047] In one possible embodiment, see Figure 1, and the sound insulation effects of the second partition wall 122 and the second soundproof glass 121 are compared. Therefore, the scale body 100 further includes a third chamber 130. The third chamber 130 is located below the second chamber 120. The third chamber 130 is provided with a detachable third soundproof glass 131. A third partition wall 132, a third sound source 133 and a third noise detector 134 are provided in the third chamber 130. The third partition wall 132 divides the third chamber 130. The third sound source 133 and the third noise detector 134 are provided on both sides of the third partition wall 132, and the third noise detector 134 is provided on a side close to the first partition wall 115. The third partition wall 132 is a partition wall used on the same floor of a simulated building (e.g., a partition wall between bedrooms). However, the sound insulation effect of the third partition wall 132 is different from that of the second partition wall 122. The second sound source 123 is first turned on, and the sound insulation effect of the second wall is measured by the second noise detector 124. The decibel level of the sound detected by the second noise detector 124 is recorded. The measurements are repeated multiple times and an average is calculated. Subsequently, the second sound source 123 and the second noise detector 124 are turned off, and the third sound source 133 (the third sound source 133 has the same structure as the second sound source 123) and the third noise detector 134 (the third noise detector 134 has the same structure as the second noise detector 124) are turned on. The detection process is the same as that of the second room 120. The decibel level of the sound detected by the second noise detector 124 is compared with the decibel level of the sound detected by the third noise detector 134 to determine the sound insulation effect of the different partition walls, allowing users to directly experience the sound insulation effect of the building before moving in.
[0048] At the same time, the second sound source 123, the third sound source 133 and the third noise detector 134 are turned off, the movable sound source 200 and the second noise detector 124 are turned on, and the movable sound source 200 is moved near the scale body 100 to emit a sound. The sound passes through the second soundproof glass 121, and the second noise detector 124 detects the decibel of the sound passing through the second soundproof glass 121. The sound is measured multiple times and the average value is taken. Subsequently, the second noise detector 124 is turned off, the third noise detector 134 is turned on, and the movable sound source 200 is moved near the scale body 100 to emit a sound. 0 and makes a sound, which passes through the third soundproof glass 131. The third soundproof glass 131 simulates architectural soundproof glass and is different from the second soundproof glass 121. The third noise detector 134 detects the decibel of the sound generated by the sound passing through the third soundproof glass 131. The decibel is measured multiple times and an average is taken. The decibel of the sound detected by the second noise detector 124 is compared with the decibel of the sound detected by the third noise detector 134 to determine the sound insulation effect of different soundproof glasses, so that users can have a direct experience of the sound insulation effect of the building before moving in.
[0049] In a possible embodiment, a third knocking member 135 is further provided in the third chamber 130 . The third knocking member 135 is provided on the third partition wall 132 and is located on one side of the third sound source 133 . In order to facilitate the comparison of the sound insulation effects of knocking on different partition walls, the detection process of the third knocking member 135 is the same as the detection process of the second knocking member 125, that is, the third knocking member 135 is started, and the third knocking member 135 knocks on the third partition wall 132 at a preset force (the third sound source 133 does not make any sound), and the knocking sound of the third knocking member 135 passes through the third partition wall 132. After the sound insulation of the third wall, the third noise detection member 134 detects the knocking sound of the third knocking member 135 and displays the decibel of the sound. It is measured multiple times and the average value is taken. By comparing the decibel of the sound detected by the second noise detection member 124 with the decibel of the sound detected by the third noise detection member 134, the sound insulation effect produced by knocking on different walls is judged, so that users can have a direct experience of the sound insulation effect of the building before moving in.
[0050] In a preferred embodiment, the third partition wall 132 is a 30mm-40mm thick aluminum plate, which is used to simulate the sound insulation performance of a 120mm-200mm hollow shale brick.
[0051] In a preferred embodiment, a noise reduction pad is attached to the third partition wall 132, and the sound insulation effect of the additional noise reduction pad can be simulated and tested.
[0052] In a preferred embodiment, the third partition wall 132 is tilted at an angle of 3°-7°. This tilted third partition wall 132 reduces sound reflections and superposition from the third sound source 133 when sound from the third sound source 133 propagates to the third partition wall 132, thereby minimizing the impact of standing sound waves on test results.
[0053] Specifically, the inclination angle of the third partition wall 132 is 3°.
[0054] Specifically, the inclination angle of the third partition wall 132 is 4°.
[0055] Specifically, the inclination angle of the third partition wall 132 is 5°.
[0056] Specifically, the inclination angle of the third partition wall 132 is 6°. The sound emitted by the third sound source 133 is detected by the third noise detector 134. When the inclination angle is 6°, the sound reflection and sound superposition caused by the sound emitted by the third sound source 133 are minimized.
[0057] Specifically, the inclination angle of the third partition wall 132 is 7°.
[0058] In one possible embodiment, see Figure 5 and Figure 6To simulate the sound insulation effect of the living room when the second soundproof glass 121 and the third soundproof glass 131 are installed, a removable fourth floor 116 is installed in the first chamber 110. That is, when the sound insulation effect of the first floor 113 does not need to be tested, the fourth floor 116 is installed horizontally in the first chamber 110. The fourth floor 116 is flush with the floor between the second chamber 120 and the third chamber 130. A slide groove 117 is provided in the first chamber 110, and the first partition wall 115 is slidably installed in the slide groove 117. The first partition wall 115 is made of a lightweight material. When the first partition wall 115 is pulled, the first room 110 is connected with the second room 120, the space is expanded, and a first living room is formed. The first room 110 is connected with the third room 130, and the space is expanded to form a second living room. That is, the upper part of the fourth floor 116 is the first living room, and the lower part is the second living room. The first soundproof glass 111 is divided into two parts. The material of the first soundproof glass 111 in the first living room is the same as that of the second soundproof glass 121. The first soundproof glass in the second living room is The material of the glass 111 is the same as that of the third soundproof glass 131. The movable sound-generating element 200 is activated, the second noise detection element 124 is turned on, and the third noise detection element 134 is turned off. The sound emitted by the movable sound-generating element 200 passes through the second soundproof glass 121. After being soundproofed by the second soundproof glass 121, the second noise detection element 124 detects the decibel of the sound after sound insulation. The sound is measured multiple times and the average value is taken. Subsequently, the third noise detection element 134 is turned on, the second noise detection element 124 is turned off, and the movable sound-generating element 200 is activated. The sound emitted by the sound-emitting element 200 passes through the third soundproof glass 131. After being soundproofed by the third soundproof glass 131, the third noise detector 134 detects the decibel of the sound after sound insulation. The sound is measured multiple times and an average is obtained. The decibel of the sound detected by the second noise detector 124 is compared with the decibel of the sound detected by the third noise detector 134 to determine the sound insulation effect of the first living room installed with the second soundproof glass 121 and the sound insulation effect of the second living room installed with the third soundproof glass 131. This allows users to have a direct experience of the sound insulation effect of the building before moving in.
