Description

Technical Field

[0001] The present invention relates to the technical field of sound insulation walls, and in particular to a prefabricated sound insulation wall for urban renewal and a method for sound insulation renovation of walls. Background Art

[0002] Existing sound insulation wall technologies play an important role in the treatment of urban noise pollution. These technologies mainly include using building materials and technological means such as walls, doors and windows, floors, and roofs to eliminate or reduce environmental noise. Building sound insulation technology can not only reduce noise pollution, but also protect the physical health and quality of living environment of surrounding residents.

[0003] During the renovation of some old walls in the process of urban renewal, in addition to paying attention to the appearance, strength and durability of the walls, more and more attention is paid to the sound insulation ability of the walls;

[0004] The common wall sound insulation renovation technologies in modern buildings mainly face the following problems and defects:

[0005] The sound insulation effect of the wall is not good, which is common in the walls of the common walls. The reasons include thin walls, poor construction quality, the use of lightweight bricks or hollow bricks, cracks in the wall and unreasonable setting of sockets, etc.

[0006] Although there is already a certain research foundation for sound insulation materials and technologies, more efficient, environmentally friendly and economical solutions still need to be explored.

[0007] Traditional wall sound insulation renovation usually realizes by adding sound insulation boards outside the original wall, and it is difficult for such sound insulation boards to form an integral body with the original wall during construction.

[0008] Therefore, it is urgent to design a prefabricated sound insulation wall for urban renewal and a supporting wall sound insulation renovation method to meet the requirements of urban renewal wall sound insulation renovation. Summary of the Invention

[0009] In order to solve the above technical problems of the sound insulation wall, the present invention provides a prefabricated sound insulation wall for urban renewal and a method for sound insulation renovation of walls. The following technical solutions are adopted:

[0010] An assembled sound insulation wall for urban renewal, the assembled sound insulation wall includes a prefabricated outer frame member, a plurality of solidification acceleration piles, a modular sound insulation inner frame member, and a chip-based acceleration solidification heating controller. The prefabricated outer frame member is installed at the wall installation position, and a sound insulation inner frame member installation groove is provided at the top. The bottoms of the plurality of solidification acceleration piles are respectively installed at the bottom of the sound insulation inner frame member installation groove of the prefabricated outer frame member. The tails of the plurality of solidification acceleration piles are connected to the acceleration solidification heating controller. The modular sound insulation inner frame member includes an outer box body, an intermediate sandwich box body, and a plurality of flexible docking members. The intermediate sandwich box body is fixedly installed in the middle of the outer box body. A plurality of flexible member docking ports are provided at the bottom of the intermediate sandwich box body, and a slow-setting sound insulation wall perfusion hole is provided at the top. A slow-setting sound insulation mixture is poured into the intermediate sandwich box body. The plurality of flexible docking members are respectively installed at the plurality of flexible member docking ports at the bottom of the intermediate sandwich box body. After the slow-setting sound insulation mixture is poured into the modular sound insulation inner frame member, one side of the plurality of flexible docking members is inserted into the sound insulation inner frame member installation groove of the prefabricated outer frame member, and the plurality of solidification acceleration piles pass through the plurality of flexible docking members and extend into the slow-setting sound insulation mixture in the intermediate sandwich box body. The plurality of solidification acceleration piles are powered on, and the acceleration solidification heating controller is operated to control the heating temperature of the plurality of solidification acceleration piles, and the heating time is set. After the heating time is reached, the acceleration solidification heating controller is removed to complete the installation of the assembled sound insulation wall.

[0011] By adopting the above technical solution, the function of the prefabricated outer frame member is to provide a more reliable and standard installation position for the modular sound insulation inner frame member. When the modular sound insulation inner frame member is assembled, it can be stuck at the sound insulation inner frame member installation groove of the prefabricated outer frame member. The plurality of solidification acceleration piles are inserted into the intermediate sandwich box body of the modular sound insulation inner frame member. A slow-setting sound insulation mixture is poured into the intermediate sandwich box body. The slow-setting sound insulation mixture is not completely solidified during prefabrication, that is, the slow-setting sound insulation mixture inside the modular sound insulation inner frame member is not completely solidified before assembly, and it can be in a flowing state or a semi-solidified state. The insertion of the plurality of solidification acceleration piles can, on the one hand, achieve the set heating power and setting under the control of the acceleration solidification heating controller, and on the other hand, can squeeze out the air in the gaps of the slow-setting sound insulation mixture. The slow-setting sound insulation mixture quickly solidifies under the heating of the plurality of solidification acceleration piles to form a sound insulation wall. Finally, after the heating time is reached, the acceleration solidification heating controller is removed to complete the installation of the assembled sound insulation wall. The assembly is fast, and the obtained sound insulation wall has outstanding sound insulation effect, high strength and stability.

[0012] Optionally, the prefabricated outer frame member includes an outer frame metal member and a sound insulation cotton cushion layer. The outer frame metal member is provided with a sound insulation inner frame member installation groove at the top. The sound insulation cotton cushion layer is laid at the bottom of the sound insulation inner frame member installation groove. The sound insulation inner frame member installation groove is provided with a plurality of solidification acceleration pile installation ports, and the plurality of solidification acceleration piles are respectively installed at the plurality of solidification acceleration pile installation ports.

[0013] By adopting the above technical solution, in order to provide a more reliable and standard installation position, the prefabricated outer frame member uses an outer frame metal part as the main body part, which is convenient to manufacture. The sound insulation cotton cushion layer is placed at the installation groove of the sound insulation inner frame member of the outer frame metal part, which can be more closely matched during assembly and can also provide a differential sound insulation layer.

[0014] Optionally, the middle sandwich box body of the modular sound insulation inner frame member protrudes from the bottom, and the protruding length is the same as the depth of the installation groove of the sound insulation inner frame member. After the middle sandwich box body of the modular sound insulation inner frame member protrudes from one side of the bottom and is inserted into the prefabricated outer frame member, the outer side surface of the prefabricated outer frame member is flush with the outer side surface of the modular sound insulation inner frame member.

[0015] By adopting the above technical solution, the middle sandwich box body protrudes from the bottom, and the protruding length is the same as the depth of the installation groove of the sound insulation inner frame member. After the assembly is completed, the outer side surface of the prefabricated outer frame member is flush with the outer side surface of the modular sound insulation inner frame member, which improves the integrity and appearance flatness of the sound insulation wall.

[0016] Optionally, both the outer frame metal part and the outer box body are made of sound-absorbing metal plates, and the middle sandwich box body is made of corrosion-resistant sound-absorbing metal plates.

[0017] By adopting the above technical solution, the material of the sound-absorbing metal plate can be a damping alloy plate, a galvanized steel plate, etc., which can provide high strength and sound-absorbing ability; the middle sandwich box body can be a stainless steel plate, an aluminum plate, etc., which can provide high strength, sound-absorbing ability and corrosion resistance, and avoid the corrosion of the slow-setting sound insulation composite material.

[0018] Optionally, the slow-setting sound insulation composite material includes mineral fiber powder, expanded perlite powder, polymer cement-based composite material and a retarder. The weight parts of the mineral fiber powder, expanded perlite powder, polymer cement-based composite material and retarder are respectively: 10 - 20 parts, 30 - 40 parts, 40 - 50 parts, 0.5 - 2 parts.

[0019] By adopting the above technical solution, prepare the mineral fiber powder, expanded perlite powder, polymer cement-based composite material and retarder according to the established ratio;

[0020] Pre-mix the mineral fiber powder and the expanded perlite powder, and then slowly add the polymer cement-based composite material containing the retarder, and continue to stir until a uniform mixture is obtained.

[0021] Pour the mixed material into the middle sandwich box body. The retarder uses a cement retarder, which can maintain the fluidity of the slow-setting sound insulation composite material for a long time. In this way, the air in the material gap is extruded after the insertion of multiple solidification acceleration piles, and it quickly solidifies under the heating of multiple solidification acceleration piles to form a sound insulation wall.

[0022] Optionally, the weight parts of the mineral fiber powder, expanded perlite powder, polymer cement-based composite material and retarder are respectively: 15 parts, 40 parts, 44 parts, 1 part.

[0023] By adopting the above technical solution and the above weight part ratio, the sound insulation effect of the sound insulation wall obtained is better.

[0024] Optionally, the multiple flexible docking parts include an outer ring part and an inner circular part. The inner circular part is located at the inner hole of the outer ring part. The outer ring part and the inner circular part are integrally formed by a rubber material in a mold. The thickness of the outer ring part is greater than 2 mm, and the thickness of the inner circular part is 0.2 mm - 0.5 mm.

[0025] By adopting the above technical solution, for the flexible docking part made of rubber material, the thickness of the inner circular part being 0.2 mm - 0.5 mm is more convenient for the insertion and piercing of the solidification acceleration pile. The relatively large thickness of the outer ring part can be sleeved at the bottom of the solidification acceleration pile to form a sealing effect. Rubber itself also has a sound insulation effect, avoiding the reduction of the sound insulation effect of the wall at these connection parts.

[0026] Optionally, the solidification acceleration pile includes a base section, a metal heating section, an open piercing tip and a temperature sensor. The bottom of the base section is installed at the solidification acceleration pile installation port. One end of the metal heating section is installed at the top of the base section, and the heat conduction wire passes through the base section and is electrically connected to the acceleration solidification heating controller. The bottom of the open piercing tip is installed at the other end of the metal heating section. The tip is used to pierce the inner circular part of the flexible docking part. After the tip of the open piercing tip pierces the inner circular part of the flexible docking part, the outer ring part is hermetically sleeved on the outer wall of the base section. The temperature sensor is installed on the outside of the metal heating section and is used to monitor the temperature of the metal heating section. The communication wire of the temperature sensor passes through the base section and is communicatively connected to the acceleration solidification heating controller.

[0027] By adopting the above technical solution, the metal heating section of the solidification acceleration pile provides electric heating. The heating process is preferably not more than the set temperature. When the temperature detected by the temperature sensor in the metal heating section area exceeds the set value, for example, 100 °C, then the heating should be stopped, and after the temperature diffuses, heating is carried out again to keep the temperature in the retarder sound insulation mixture from being locally too high. At a relatively high temperature, the retarder sound insulation mixture quickly solidifies to form a sound insulation wall.

[0028] Optionally, the acceleration solidification heating controller includes a buffer, a circuit board based on a main control chip and a touch display screen. The buffer is communicatively connected to the temperature sensor respectively. The circuit board is communicatively connected to the buffer and controls the heating power of multiple solidification acceleration piles respectively based on the temperature data of the temperature sensor. The circuit board controls the display content of the touch display screen, and the parameters of the heating time and heating power of multiple solidification acceleration piles are set respectively by operating the touch display screen.

[0029] A method for sound insulation renovation of walls for urban renewal, which uses an assembled sound insulation wall for urban renewal to carry out sound insulation renovation of walls, including the following steps:

[0030] Step 1: Install the outer frame metal parts at the bottom of the installation position of the sound insulation wall, with the installation slots of the sound insulation inner frame parts facing upwards. Install multiple solidification acceleration piles at the multiple installation openings of the solidification acceleration piles respectively. Open openings at the positions corresponding to the multiple solidification acceleration piles, and lay the sound insulation cotton cushion layer at the bottom of the installation slots of the sound insulation inner frame parts;

[0031] Step 2: Prepare a retarder sound insulation mixture according to the weight ratio of 15:40:44:1 of mineral fiber powder, expanded perlite powder, polymer cement-based composite material, and retarder. Pour the prepared retarder sound insulation mixture into the retarder sound insulation wall pouring hole at the top of the middle sandwich box body of the modular sound insulation inner frame part;

[0032] Step 3: Align and sleeve the multiple flexible docking parts at the bottom of the modular sound insulation inner frame part completed in Step 2 with the multiple solidification acceleration piles respectively;

[0033] Step 4: Set the heating time and heating power through the acceleration solidification heating controller, and start heating and solidifying the retarder sound insulation mixture in the modular sound insulation inner frame part;

[0034] Step 5: After reaching the heating time, remove the acceleration solidification heating controller to complete the sound insulation renovation of the wall.

[0035] In summary, the present invention includes at least one of the following beneficial technical effects:

[0036] The present invention can provide an assembled sound insulation wall for urban renewal and a method for sound insulation renovation of walls. The prefabricated outer frame parts provide a more reliable and standard installation position for the modular sound insulation inner frame parts. The modular sound insulation inner frame parts are stuck at the installation slots of the sound insulation inner frame parts of the prefabricated outer frame parts during assembly. Multiple solidification acceleration piles are inserted into the middle sandwich box body of the modular sound insulation inner frame parts. The middle sandwich box body is filled with a retarder sound insulation mixture. The retarder sound insulation mixture is not completely solidified during prefabrication. The insertion of multiple solidification acceleration piles can, on the one hand, achieve the set heating power and setting under the control of the acceleration solidification heating controller, and on the other hand, can extrude the air in the gaps of the retarder sound insulation mixture. The retarder sound insulation mixture quickly solidifies under the heating of multiple solidification acceleration piles to form a sound insulation wall. Finally, after reaching the heating time, remove the acceleration solidification heating controller to complete the installation of the assembled sound insulation wall. The assembly is fast, and the obtained sound insulation wall has outstanding sound insulation effect, high strength and stability. Description of the Drawings

[0046] The function of the prefabricated outer frame member 1 is to provide a more reliable and standard installation position for the modular sound insulation inner frame member 3. When the modular sound insulation inner frame member 3 is assembled, it can be stuck at the sound insulation inner frame member installation groove 111 of the prefabricated outer frame member 1. The plurality of solidification acceleration piles 2 are inserted into the intermediate sandwich box body 32 of the modular sound insulation inner frame member 3.

The insertion of the plurality of solidification acceleration piles 2 can, on the one hand, achieve the set heating power and setting under the control of the acceleration solidification heating controller 4, and on the other hand, can extrude the air in the gaps of the slow-setting sound insulation mixture. The slow-setting sound insulation mixture quickly solidifies under the heating of the plurality of solidification acceleration piles 2 to form a sound insulation wall. Finally, after the heating time is reached, the acceleration solidification heating controller 4 is removed to complete the installation of the assembled sound insulation wall. The assembly is fast, and the obtained sound insulation wall has outstanding sound insulation effects, high strength and stability.

[0047] Embodiment 2. The prefabricated outer frame member 1 includes an outer frame metal member 11 and a sound insulation cotton cushion layer 12. A sound insulation inner frame member installation groove 111 is provided at the top of the outer frame metal member 11. The sound insulation cotton cushion layer 12 is laid at the bottom of the sound insulation inner frame member installation groove 111. The sound insulation inner frame member installation groove 111 is provided with a plurality of solidification acceleration pile installation openings, and a plurality of solidification acceleration piles 2 are respectively installed at the plurality of solidification acceleration pile installation openings.

[0048] In order to provide a more reliable and standard installation position, the prefabricated outer frame member 1 uses the outer frame metal member 11 as the main body member, which is convenient to manufacture. The sound insulation cotton cushion layer 12 is padded at the sound insulation inner frame member installation groove 111 of the outer frame metal member 11, which can be more closely matched during assembly and can also provide a differential sound insulation layer.

[0049] Embodiment 3. The middle sandwich box body 32 of the modular sound insulation inner frame member 3 protrudes from the bottom, and the protruding length is the same as the depth of the sound insulation inner frame member installation groove 111. When the middle sandwich box body 32 of the modular sound insulation inner frame member 3 protrudes from one side of the bottom and is inserted into the prefabricated outer frame member 1, the outer side surface of the prefabricated outer frame member 1 is flush with the outer side surface of the modular sound insulation inner frame member 3.

[0050] The middle sandwich box body 32 protrudes from the bottom, and the protruding length is the same as the depth of the sound insulation inner frame member installation groove 111. After the assembly is completed, the outer side surface of the prefabricated outer frame member 1 is flush with the outer side surface of the modular sound insulation inner frame member 3, which improves the integrity and appearance flatness of the sound insulation wall.

[0051] Embodiment 4. Both the outer frame metal member 11 and the outer box body 31 are made of sound-absorbing metal plates, and the middle sandwich box body 32 is made of corrosion-resistant sound-absorbing metal plates.

[0052] The material of the sound-absorbing metal plate can be a damping alloy plate, a galvanized steel plate, etc., which can provide high strength and sound-absorbing ability; the middle sandwich box body 32 can be a stainless steel plate, an aluminum plate, etc., which can provide high strength, sound-absorbing ability and corrosion-resistant ability to avoid the corrosion of the slow-setting sound insulation composite material.

[0053] Embodiment 5. The slow-setting sound insulation composite material includes mineral fiber powder, expanded perlite powder, polymer cement-based composite material and a retarder. The weight parts of the mineral fiber powder, expanded perlite powder, polymer cement-based composite material and retarder are respectively: 10 - 20 parts, 30 - 40 parts, 40 - 50 parts, 0.5 - 2 parts.

[0054] Prepare the mineral fiber powder, expanded perlite powder, polymer cement-based composite material and retarder according to the established ratio;

[0055] Pre-mix the mineral fiber powder and the expanded perlite powder, and then slowly add the polymer cement-based composite material containing the retarder, and continue to stir until a uniform mixture is obtained.

[0056] Pour the mixed materials into the intermediate sandwich box body 32. The retarder uses a cement retarder, which can maintain the fluidity of the retarder sound insulation mixed materials for a long time. In this way, after the insertion of multiple solidification acceleration piles 2, the air in the material gaps is extruded, and it quickly solidifies under the heating of multiple solidification acceleration piles 2 to form a sound insulation wall.

The test results are as follows:

[0060] ASTM C423: Test results:

[0061] Sound insulation amount:

[0062] Test frequency range: 125 Hz - 4000 Hz

[0063] STC rating: 45 dB

[0064] Sound insulation amount at detailed frequencies:

[0065] 125 Hz: 35 dB; 250 Hz: 40 dB; 500 Hz: 45 dB; 1000 Hz: 50 dB; 2000 Hz: 48 dB; 4000 Hz: 43 dB;

[0070] 200 Hz: 0.60; 500 Hz: 0.65; 1000 Hz: 0.70; 2000 Hz: 0.60

[0071] According to the test standards of ASTM E90 and ASTM C423, the sound insulation board prepared with mineral fiber, expanded perlite, polymer cement-based composite material and retarder shows good sound insulation performance. The sound insulation amount of the sound insulation board in the medium frequency range reaches 45 dB, and the average sound absorption coefficient is 0.65, indicating that this material is suitable for applications that require sound insulation and sound absorption.

[0072] Example 7, a plurality of flexible docking members 33 include an outer ring member 331 and an inner circular member 332. The inner circular member 332 is located at the inner hole of the outer ring member 331. The outer ring member 331 and the inner circular member 332 are integrally molded by a rubber material. The thickness of the outer ring member 331 is greater than 2 mm, and the thickness of the inner circular member 332 is 0.2 mm - 0.5 mm.

[0073] For the flexible docking member 33 made of rubber material, the thickness of the inner circular member 332 being 0.2 mm - 0.5 mm is more convenient for the insertion and piercing of the solidification acceleration pile 2. The relatively large thickness of the outer ring member 331 can be sleeved at the bottom of the solidification acceleration pile 2 to form a sealing effect. Rubber itself also has sound insulation effect, avoiding the reduction of the sound insulation effect of the wall at these connection parts.

[0074] Example 8, the solidification acceleration pile 2 includes a base section 21, a metal heating section 22, an open piercing tip 23 and a temperature sensor 24.

The bottom of the open piercing tip 23 is installed at the other end of the metal heating section 22. The tip is used to pierce the inner circular member 332 of the flexible docking member 33. After the tip of the open piercing tip 23 pierces the inner circular member 332 of the flexible docking member 33, the outer ring member 331 is hermetically sleeved on the outer wall of the base section 21. The temperature sensor 24 is installed outside the metal heating section 22 to monitor the temperature of the metal heating section 22. The communication wire of the temperature sensor 24 passes through the base section 21 and is communicatively connected to the acceleration solidification heating controller 4.

[0075] The metal heating section 22 of the solidification acceleration pile 2 provides electric heating. The heating process is preferably not to exceed the set temperature. When the temperature detected by the temperature sensor 24 in the area of the metal heating section 22 exceeds the set value, such as 100 °C, then the heating should be stopped, and after the temperature diffuses, heating is carried out again to keep the temperature in the retarder sound insulation mixture from being locally too high. At a relatively high temperature, the retarder sound insulation mixture quickly solidifies to form a sound insulation wall.
