Description

Technical Field

[0001] This utility model belongs to the field of wall technology, specifically a thermal insulation and soundproof wall structure based on microporous damping elastomer. Background Technology

[0002] As an important component of building structure, walls are not only the basic elements for load-bearing and enclosure of buildings, but also the carriers of architectural aesthetics and functionality. They are usually made of concrete.

[0003] In existing technologies, traditional building walls have significant defects in terms of thermal insulation and sound insulation: on the one hand, ordinary brick walls or concrete walls have high thermal conductivity, and indoor heat is easily lost through the walls in winter, while outdoor heat radiation quickly enters the room in summer, resulting in high building air conditioning energy consumption; on the other hand, traditional walls have limited ability to block sound waves, especially low-frequency noise such as traffic noise and equipment vibration, which can easily penetrate the walls, and ordinary plaster layers or single board structures are difficult to form an effective sound barrier. To address this, we propose a thermal insulation and sound insulation wall structure based on microporous damping elastomers. Utility Model Content

[0004] The purpose of this invention is to provide a thermal insulation and soundproof wall structure based on microporous damping elastomer to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermal insulation and soundproof wall structure based on microporous damping elastomer, comprising a concrete matrix, wherein a microporous damping elastomer plate is provided on one side of the concrete matrix for the purpose of thermal insulation and soundproofing.

[0006] A bonding mortar is provided between the microporous damping elastomer plate and the concrete matrix. A waterproof and breathable membrane is provided on the side of the microporous damping elastomer plate. A vacuum insulation board is provided on the side of the waterproof and breathable membrane. A honeycomb cavity board is provided on the side of the vacuum insulation board. The honeycomb cavity board is filled with sound-absorbing cotton.

[0007] The honeycomb cavity panel has multiple interior trim panels on its side.

[0008] Preferably, a plurality of connecting columns are fixedly provided on one side of the concrete substrate, and a horizontal keel is fixedly provided at the end of the connecting column.

[0009] Preferably, multiple sets of vertical keels are fixedly provided on the side of the horizontal keel.

[0010] Preferably, one side of the interior panel is provided with a protrusion, and the interior of the vertical keel is provided with a slot for the protrusion to be inserted and engaged.

[0011] Preferably, the connecting column is fixedly connected to the horizontal keel, and the horizontal keel is fixedly connected to the vertical keel by welding.

[0012] Preferably, a carbon fiber cloth is provided on the other side of the concrete matrix, an adhesive is provided between the carbon fiber cloth and the concrete matrix, and a quartz sand roughening layer is provided on the side of the carbon fiber cloth.

[0013] Preferably, a cement mortar layer is provided on the side of the quartz sand roughening layer, and an external protective paint is sprayed on the side of the cement mortar layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model combines the designed connecting column, vertical keel, interior panel, horizontal keel, honeycomb cavity panel, sound-absorbing cotton, vacuum insulation panel, waterproof and breathable membrane, microporous damping elastomer board and adhesive mortar. Through the heat insulation structure of the microporous damping elastomer board and the vacuum insulation panel, the heat transfer coefficient of the concrete matrix is ​​reduced, which reduces the heat conduction compared with the traditional concrete matrix. This effectively solves the energy consumption problem of heat loss in winter and poor heat insulation in summer. At the same time, the microporous damping elastomer board absorbs low-frequency noise using the Helmholtz resonance principle. Combined with the honeycomb cavity panel and sound-absorbing cotton to dissipate mid-to-high frequency noise, the sound insulation of the wall air is improved, which significantly blocks traffic noise and indoor vibration.

[0016] (2) This utility model combines an adhesive, an external protective paint, a cement mortar layer, a quartz sand roughening layer, and a carbon fiber cloth. Through the design of reinforcement, protection, and beautification, it significantly improves the structural performance and durability of the wall. The carbon fiber cloth is tightly bonded to the concrete substrate with the help of the adhesive. Its high strength characteristics can repair cracks in the concrete substrate and improve the load-bearing capacity, solving the problem of insufficient load-bearing capacity caused by material deterioration in traditional walls. The quartz sand roughening layer increases the surface roughness, which improves the adhesion of the cement mortar layer and prevents the cement mortar layer from detaching and peeling off in the later stage. Together with the external protective paint, it forms a continuous waterproof barrier, blocking the path of rainwater penetration and concrete carbonization. At the same time, the weather-resistant coating of the external protective paint can resist environmental erosion such as acid rain and ultraviolet rays, maintaining the long-term stable mechanical properties and waterproof effect of the concrete substrate.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1

[0023] Please see Figures 1-3 This utility model provides a technical solution: a thermal insulation and soundproof wall structure based on microporous damping elastomer, including a concrete substrate 100, and a microporous damping elastomer plate 209 provided on one side of the concrete substrate 100 for thermal insulation and sound insulation. The microporous damping elastomer plate 209 can effectively block high-frequency noise and low-frequency noise. It reduces vibration and noise by consuming vibration energy. Its working principle is based on the Helmholtz resonance principle, that is, when sound waves enter the micropores, they will generate vibration inside and consume sound energy, which is converted into heat energy and dissipated. This material has high resilience, high damping and adhesion, and can absorb low-frequency solid-borne sound, such as footsteps and impact sounds, thereby providing excellent sound insulation, vibration reduction and noise reduction effects.

[0024] An adhesive mortar 210 is provided between the microporous damping elastomer plate 209 and the concrete substrate 100. The adhesive mortar 210 facilitates the adhesion of the microporous damping elastomer plate 209 to the concrete substrate 100. A waterproof and breathable membrane 208 is provided on the side of the microporous damping elastomer plate 209 to prevent outdoor moisture from entering the room. A vacuum insulation board 207 is provided on the side of the waterproof and breathable membrane 208. The vacuum insulation board 207 is vacuum-treated to effectively prevent heat transfer caused by air convection. Its thermal conductivity is extremely low, and this material can significantly reduce heat loss. The vacuum insulation panel 207 has a honeycomb cavity panel 205 on its side, which is filled with sound-absorbing cotton 206. The hollow design of the honeycomb cavity panel 205 gives it good sound insulation and heat insulation performance, effectively absorbs and disperses impact force, and provides excellent impact resistance. The sound-absorbing cotton 206 can absorb sound wave energy through its porous structure and convert it into heat energy, thereby reducing sound intensity and improving sound quality. It can also play a role in vibration reduction and heat insulation.

[0025] Multiple interior trim panels 202 are provided on the side of the honeycomb cavity panel 205;

[0026] The interior panel 202 has a protrusion on one side, and the interior of the vertical keel 201 has a slot for the protrusion to be inserted and engaged.

[0031] Example 3

[0032] Please refer to Example 2. Figure 1On the other side of the concrete substrate 100, a carbon fiber cloth 304 is provided. The main function of the carbon fiber cloth 304 is to reinforce, repair and improve the load-bearing capacity of the concrete substrate 100. The carbon fiber cloth 304 has the characteristics of high strength, light weight and corrosion resistance. Its tensile strength is several times that of ordinary steel, while its weight is light. These characteristics make the carbon fiber cloth 304 have significant advantages in the reinforcement of the concrete substrate 100. An adhesive 300 is provided between the carbon fiber cloth 304 and the concrete substrate 100. A quartz sand roughening layer 303 is provided on the side of the carbon fiber cloth 304. The quartz sand roughening layer 303 can increase the surface roughness, improve the adhesion of the cement mortar layer 302 and prevent the coating from falling off.

[0033] A cement mortar layer 302 is provided on the side of the quartz sand roughening layer 303, and an external protective paint 301 is sprayed on the side of the cement mortar layer 302, which can protect the concrete substrate 100, enhance waterproof performance, increase hardness and beautify the appearance.
