Description

Technical Field

[0001] This utility model relates to the field of building walls, specifically energy-saving and environmentally friendly building walls. Background Technology

[0002] Walls mainly include load-bearing walls and non-load-bearing walls, which primarily serve to enclose and divide space. There are many types of walls, including walls made of single materials and walls made of composite materials. Taking into account factors such as enclosure, load-bearing capacity, energy conservation, and aesthetics, designing a reasonable wall scheme is an important task in building construction.

[0003] In the prior art, such as in publication number CN214657984U, a novel energy-saving and environmentally friendly building wall is disclosed. It includes a building wall with an inner cavity containing a sound insulation chamber. A perforated wood sound-absorbing board is fixedly installed in the middle of the inner cavity. Sound-absorbing cotton is adhered to the right side of the perforated wood sound-absorbing board, and a grooved wood sound-absorbing board is adhered to the left side. Recycled wood sound-absorbing boards are adhered to both sides of the building wall. This invention, through the arrangement of the building wall, sound insulation chamber, grooved wood sound-absorbing board, perforated wood sound-absorbing board, sound-absorbing cotton, recycled wood sound-absorbing board, polyester fiber sound-absorbing board, and asbestos sound insulation board, effectively improves the sound insulation effect. It solves the problems of poor sound insulation in existing building walls, which not only easily affect people's rest due to external factors but also easily expose people's daily privacy, causing inconvenience, and have poor waterproof and fireproof properties.

[0004] While the aforementioned patents improve the sound insulation of walls through structures such as sound insulation cavities, grooved wood sound-absorbing panels, perforated wood sound-absorbing panels, sound-absorbing cotton, recycled wood sound-absorbing panels, polyester fiber sound-absorbing panels, and asbestos sound insulation panels, the structures are relatively complex, and the accumulation of a large amount of sound insulation materials greatly increases the cost of the walls, making them less energy-efficient and environmentally friendly. At the same time, the lack of structural reinforcement to enhance the compressive strength of the walls means that the accumulation of a large amount of sound insulation structures will affect the strength of the walls. Therefore, an energy-saving and environmentally friendly building wall is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as complex structures and excessive use of sound insulation materials which significantly increase wall costs and are not energy-efficient or environmentally friendly, this invention proposes an energy-saving and environmentally friendly building wall.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: the energy-saving and environmentally friendly building wall of this utility model includes an outer wall, a support structure is fixedly connected to the side of the outer wall, a protective layer is fixedly connected to the side of the support structure, an inner wall is fixedly connected to the side of the protective layer, and an installation plate is fixedly connected to the side of both the outer wall and the inner wall.

[0007] The supporting structure includes a honeycomb wall fixedly connected to the back of the outer wall, and the surface of the honeycomb wall is covered with a reflective film layer;

[0008] The protective layer includes a sealed cavity disposed between the inner wall and the supporting structure, and a vacuum layer is provided inside the sealed cavity.

[0009] Preferably, the honeycomb wall of the supporting structure is made of lightweight composite material, and its surface is covered with a reflective film layer to reflect solar radiation.

[0010] Preferably, the sealed cavity of the protective layer is a closed cavity structure, and the vacuum layer is filled inside the sealed cavity to reduce heat conduction.

[0011] Preferably, the mounting plates on the sides of the outer and inner walls are made of composite materials and are fixedly connected to the wall by bolts.

[0012] Preferably, the inner wall of the sealed cavity of the vacuum layer is coated with a sound-insulating coating to enhance the sound insulation effect.

[0013] Preferably, the end of the mounting plate is provided with a mating plane for splicing with the adjacent wall, and the mating plane is directly connected to the mounting plate of the adjacent wall by fasteners.

[0014] The advantages of this utility model are:

[0015] 1. This utility model combines the honeycomb wall and reflective film layer in the support structure, and integrates the sealed cavity of the protective layer with the vacuum layer. While simplifying the wall structure, it reduces material consumption by utilizing the lightweight characteristics of the honeycomb porous structure. The vacuum layer forms a medium-free cavity that directly blocks the transmission of sound waves and the conduction of heat, replacing the traditional multi-layer sound insulation material stacking. This significantly reduces construction costs and improves environmental protection. At the same time, the reflective film layer can actively reflect solar radiation to reduce building energy consumption.

[0016] 2. This utility model adopts a biomimetic porous structure for the honeycomb wall of the supporting structure, which significantly improves the compressive strength and load distribution uniformity of the wall, avoiding the problem of weakened load-bearing capacity caused by loose accumulation of traditional sound insulation filling materials. At the same time, the medium-free environment formed by the vacuum layer in the sealed cavity not only blocks the transmission of sound waves, but also enhances the overall stability of the wall through the rigid cavity structure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, the energy-saving and environmentally friendly building wall includes an outer wall 1, a support structure 2 fixedly connected to the side of the outer wall 1, a protective layer 3 fixedly connected to the side of the support structure 2, an inner wall 4 fixedly connected to the side of the protective layer 3, and mounting plates 5 fixedly connected to the sides of both the outer wall 1 and the inner wall 4; the support structure 2 includes a honeycomb wall 21 fixedly connected to the back of the outer wall 1, and the surface of the honeycomb wall 21 is covered with a reflective film layer 22;

[0025] During operation, the outer wall 1 and the inner wall 4 are first pre-fixed to the building frame using mounting plates 5. Then, the support structure 2 is fixedly installed on the back of the outer wall 1. The honeycomb wall 21 of the support structure 2 is made of lightweight composite material and has built-in porous honeycomb units. Its surface is covered with a reflective film layer 22 by vacuum coating process to reflect solar radiation.

[0026] Furthermore, the protective layer 3 includes a sealed cavity 31 disposed between the inner wall 4 and the supporting structure 2, and a vacuum layer 32 is disposed inside the sealed cavity 31.

[0027] During operation, a protective layer 3 is constructed between the supporting structure 2 and the inner wall 4. The sealed cavity 31 of the protective layer 3 is formed by sealing the edges of the outer wall 1 and the inner wall 4, and a vacuum layer 32 is formed by evacuating the cavity. The vacuum environment is used to block the transmission of sound waves and the path of heat conduction.

[0028] Furthermore, the honeycomb wall 21 of the supporting structure 2 is made of lightweight composite material, and its surface is covered with a reflective film layer 22 for reflecting solar radiation.

[0029] During operation, the honeycomb wall 21 of the supporting structure 2 is integrally formed using a lightweight composite material through a molding process. Its surface is covered with a reflective film layer 22 through a vacuum coating or spraying process. The reflective film layer 22 is made of aluminum-based or ceramic-based high-reflective materials to maximize solar radiation reflection efficiency. The porous structure of the honeycomb wall 21 reduces the amount of material used and improves the overall compressive strength. At the same time, the reflective film layer 22 actively reflects sunlight to reduce heat absorption on the building's exterior surface. This simplifies the structure while achieving lightweight walls and controlling building energy consumption, effectively solving the problems of high cost and insufficient environmental protection caused by the accumulation of sound insulation materials in traditional walls.

[0030] Furthermore, the sealed cavity 31 of the protective layer 3 is a closed cavity structure, and the vacuum layer 32 is filled inside the sealed cavity 31 to reduce heat conduction.

[0031] During operation, the sealed cavity 31 of the protective layer 3 is formed by sealing and welding or gluing the edges of the outer wall 1 and the inner wall 4 to form a sealed cavity. A vacuum is then drawn into the cavity to a pressure ≤10Pa to form a vacuum layer 32. The inner wall of the vacuum layer 32 can be further coated with a nano-sound insulation coating to enhance sound wave absorption. This design blocks the sound wave transmission medium and eliminates air heat convection through a vacuum environment, so that the wall can achieve the same sound insulation effect without relying on traditional multi-layer sound insulation cotton or rock wool filling. At the same time, it significantly reduces the thermal conductivity coefficient, taking into account both sound insulation performance optimization and energy-saving and environmental protection goals, and overcoming the structural complexity and material redundancy defects of the background technology.

[0032] Working Principle: Functional optimization is achieved through the synergistic action of the supporting structure 2 and the protective layer 3 between the outer wall 1 and the inner wall 4. The honeycomb wall 21 of the supporting structure 2 adopts a porous biomimetic structure to improve compressive strength and reduce material usage. The reflective film layer 22 covering its surface reduces heat absorption of the outer wall 1 by reflecting solar radiation. The vacuum layer 32 is set in the sealed cavity 31 of the protective layer 3, which uses the vacuum environment to block the sound wave transmission medium and heat conduction path. At the same time, the airtight structure of the sealed cavity 31 ensures the long-term stability of the vacuum layer 32. The mounting plates 5 on the sides of the outer wall 1 and the inner wall 4 are connected to the main building structure by bolts or welding to ensure rapid assembly of the wall modules and overall mechanical performance. Finally, through the lightweight load-bearing capacity of the honeycomb wall 21, the active heat reflection of the reflective film layer 22, the sound and heat dual barrier of the vacuum layer 32, and the rigid connection of the mounting plates 5, the integrated goal of structural simplification, energy consumption reduction and environmental protection performance improvement is achieved.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
