Description

Technical Field

[0001] This utility model relates to the field of building wall structure technology, and in particular to a green and energy-saving building wall structure. Background Technology

[0002] Green and energy-efficient building walls are building envelope structures that achieve efficient thermal insulation, heat insulation, and noise reduction through environmentally friendly materials, energy-saving technologies, and intelligent design. Environmentally friendly materials, such as recycled aggregate concrete and straw fiberboard, not only reduce resource consumption but also effectively block heat transfer through their low thermal conductivity. In terms of energy-saving technologies, phase change energy storage materials can dynamically regulate indoor temperature fluctuations, and photovoltaic integrated wall systems convert solar energy into clean energy, while heat-reflective coatings reduce heat radiation absorption.

[0003] Patent document CN209509370U discloses an energy-saving exterior wall insulation and decorative panel, including a base plate. The base plate has an installation groove on its side and an installation recess at its bottom. A sound insulation assembly is fixedly installed on the top of the base plate with screws. The sound insulation assembly includes a lower sound insulation cotton and a corresponding upper sound insulation cotton above it. A support column is provided between the upper and lower sound insulation cotton. An insulation assembly is installed above the sound insulation assembly. The sound insulation assembly effectively reduces noise, providing a quieter working and sleeping environment, making it more practical. Furthermore, the wallpaper installation assembly effectively protects the internal sound insulation and insulation assemblies. When the wallpaper installation assembly ages over time, it can be disassembled and replaced separately. Similarly, when the sound insulation and insulation assemblies reach the end of their service life, they can also be disassembled and replaced separately, effectively reducing user costs and making it more practical.

[0004] As with the prior art of the aforementioned patent, sound insulation components are generally required to be installed inside building walls to isolate external noise. In the prior art, most sound insulation materials need to be installed at the keel position inside the wall, and as in the patent above, the keel and sound insulation cotton layer are connected by bolts and other structures. However, this assembly method requires replacing the original sound insulation cotton layer structure. On the one hand, the installation process requires completing steps such as positioning, drilling, and bolt fixing in sequence. Not only is it necessary to accurately measure the hole spacing to match the keel spacing, but it is also necessary to additionally treat the burrs on the edge of the hole to avoid tearing the material, which leads to a longer construction period and increased process complexity. On the other hand, opening holes will directly destroy the continuous and dense structure of the sound insulation cotton layer, which greatly reduces the sound insulation effect of the sound insulation cotton. Utility Model Content

[0005] The purpose of this utility model is to provide a green and energy-saving building wall structure to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a green and energy-saving building wall structure, including a concrete layer, an insulation layer on the concrete layer, a base plate fixedly installed on the insulation layer by structural adhesive, multiple overlapping grooves on the base plate, a keel frame fixedly installed inside the multiple overlapping grooves, the keel frame being composed of multiple steel bars, multiple sound insulation components being arranged between the multiple steel bars, the keel frame also including an installation frame for fixing and assembling the sound insulation components, the sound insulation component including two clamping plates, a sound insulation cotton filling layer disposed between the clamping plates, and an elastic element, the elastic element being uniformly serrated and wavy, the sound insulation cotton filling layer filling the gap between the elastic element and the sound insulation felt, and a gypsum board fixedly installed on the top of the installation frame.

[0007] As a further description of the above technical solution: the steel strip has an installation cavity that extends through both ends of the steel strip, and the interior of the installation cavity is filled with sound-insulating cotton strips.

[0008] As a further description of the above technical solution: the steel strip has two through holes on its surface, the mounting frame is composed of four parallel parts and two vertical parts, and the sound insulation component has two grooves on the side of the clamping plate near the mounting frame, and the two grooves are fitted into the two vertical parts of the mounting frame.

[0009] As a further description of the above technical solution: multiple screws are fixedly installed on the mounting frame, and the multiple screws pass through multiple through holes to enter the interior of the mounting cavity and are locked with nuts.

[0010] As a further description of the above technical solution: both ends of the steel bar are sealed by sealing elements.

[0011] As a further description of the above technical solution: the sound insulation component also includes two sound insulation felts disposed between two clamping plates, the two sound insulation felts are respectively fixedly installed on the two clamping plates, the sound insulation felts are connected to the sound insulation cotton filling layer, and the elastic element is fixedly connected to the two sound insulation felts through an adhesive.

[0012] This utility model provides a green and energy-saving building wall structure. It has the following beneficial effects: The basic thermal insulation and sound insulation performance of the wall is achieved by setting up an insulation layer and sound insulation components. The sound insulation components are fixedly assembled on the steel bars of the keel frame by the mounting frame, without the need to drill holes in the sound insulation components, thus ensuring the integrity of the sound insulation components and the sound insulation effect.

[0013] By combining a serrated wave-shaped elastic element with a sound-insulating cotton filling layer, the two work synergistically to achieve efficient broadband sound insulation. As a porous material, the sound-insulating cotton mainly absorbs and consumes mid- and high-frequency sound energy through friction and viscosity. The uniform serrated wave-shaped elastic element, on the one hand, interrupts vibration transmission through its elasticity, and on the other hand, forces sound waves (especially low-frequency sound waves) to repeatedly reflect and interfere inside through its tortuous cavity structure, thereby significantly attenuating sound energy. The combination of the two, with the elastic element providing support for the sound-insulating cotton and the sound-insulating cotton damping vibration and enhancing sound absorption, together constitutes a composite sound insulation system covering the entire frequency band.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0015] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

The sawtooth wave-shaped elastic element 502 and the sound insulation cotton filling layer 504 work together to achieve efficient broadband sound insulation. As a porous material, the sound insulation cotton mainly absorbs and consumes mid- and high-frequency sound energy through friction and adhesion. The uniform sawtooth wave-shaped elastic element 502, on the one hand, interrupts the vibration transmission through its elasticity, and on the other hand, forces the sound waves (especially low-frequency sound waves) to repeatedly reflect and interfere inside through the tortuous cavity structure, thereby significantly attenuating the sound energy.
