Description

Technical Field

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

[0002] Energy-saving and noise-reducing wall panels are wall structures with energy-saving and noise-reducing functions, designed to improve the energy efficiency and living comfort of buildings. With increasing public awareness of environmental protection, energy-saving and noise-reducing wall panels, as an environmentally friendly building material and technology, align with modern architectural development trends and environmental requirements, contributing to the sustainable development of the construction industry.

[0003] Chinese patent CN222227795U discloses an energy-saving and environmentally friendly building wall panel installation structure, including an inner wall and wall panels. Multiple wall panels are arranged in a matrix on the outer side of the inner wall and fixed together by positioning components on the outer side. An inner support component is provided between the inner wall and the wall panels. This energy-saving and environmentally friendly building wall panel installation structure not only provides a stable wall structure and precise wall panel alignment, but also simplifies the installation process and enhances structural stability. Simultaneously, it improves the wall's seismic resistance and noise reduction, providing a safer and more comfortable living environment for building users.

[0004] However, the above technical solution has the following shortcomings: Although the wall panel can play a role in noise reduction, it only relies on elastic support pads for noise reduction, which is generally not very effective. Furthermore, when the wall panel is installed horizontally, the lack of a positioning and fixing structure means that when the edge plate is used to fix the wall panel, not only do multiple people need to assist in the support and fixing, but there may also be gaps between the joints of the horizontal wall panels, which affects the performance of the wall panel. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing an energy-saving and noise-reducing wall structure that not only has good noise reduction and heat insulation performance, but also reduces the difficulty of wall installation, avoids obvious gaps at the joints, and improves the practicality of the wall.

[0006] The technical solution of this utility model is an energy-saving and noise-reducing wall structure, including an inner wall and a horizontal splicing assembly; an outer wall is provided on the inner wall, the outer wall including an extruded polystyrene board, a thermal insulation mortar layer provided on the extruded polystyrene board, an inner panel provided on the thermal insulation mortar layer, a noise-reducing board provided inside the inner panel, and a sound-insulating cotton board provided on the noise-reducing board; the horizontal splicing assembly includes a connecting frame and a fitting plate provided on the outer wall, and two first bolts penetrating the connecting frame and the fitting plate; the first bolts are threadedly connected to the inner wall.

[0007] Preferably, the exterior wall also includes a decorative panel set on the sound insulation cotton panel.

[0008] Preferably, the noise reduction board has multiple sound-absorbing cavities inside.

[0009] Preferably, the connecting frame is provided with a rectangular groove, and an elastic sealing gasket is provided inside the groove, with the fitting plate embedded inside the groove.

[0010] Preferably, an installation assembly is provided between the upper and lower outer walls. The installation assembly includes an installation plate, a locking block on the installation plate, two pressure plates symmetrically distributed on the installation plate, and a plurality of second bolts that penetrate the installation plate and the locking block; the second bolts are threadedly connected to the inner wall.

[0011] Preferably, the card block is located between the upper and lower outer walls and abuts against each other, and the pressure plate abuts against the outer wall.

[0012] Preferably, the mounting plate is provided with multiple countersunk holes, and the second bolt is located inside the countersunk holes.

[0013] Preferably, the mounting plate and the pressure plate are provided with multiple reinforcing ribs arranged in a linear array.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] 1. This utility model uses extruded polystyrene board and thermal insulation mortar layer to make the wall have an extremely low thermal conductivity, which can prevent indoor heat loss in winter and reduce heat absorption in summer, making the indoor temperature more comfortable and stable. At the same time, the noise reduction board and sound insulation cotton board can effectively reduce the phenomenon of sound passing through the wall and further propagating, which has a highly efficient noise reduction effect.

[0016] 2. The horizontal splicing components of this utility model not only play a role in pre-fixing the external wall, but also further improve the stability of the structure in conjunction with the installation components. They can also avoid the drawback of obvious gaps at the joints of the external wall, and reduce the operational difficulty during the installation of the external wall, thus having good practicality.

[0022] Example 1

[0023] like Figures 1-4 As shown in the figure, this embodiment proposes an energy-saving and noise-reducing wall structure, including an inner wall 1 and a horizontal splicing component; an outer wall 2 is provided on the inner wall 1, and the outer wall 2 includes an extruded polystyrene board 9, a thermal insulation mortar layer 5 provided on the extruded polystyrene board 9, an inner panel 6 provided on the thermal insulation mortar layer 5, a noise-reducing board 7 provided inside the inner panel 6, and a sound-insulating cotton board 4 provided on the noise-reducing board 7. The noise-reducing board 7 has multiple sound-absorbing cavities 8 inside, and the outer wall 2 also includes a decorative panel 3 provided on the sound-insulating cotton board 4; the extruded polystyrene board 9 has an extremely low thermal conductivity, which can prevent indoor heat loss in winter and reduce heat absorption in summer. Combined with the thermal insulation mortar layer 5, it can make the indoor temperature more comfortable and stable, and at the same time play an energy-saving role; the setting of the noise-reducing board 7 and the sound-insulating cotton board 4 can shear sound waves into heat energy, achieve a sound absorption effect, effectively reduce the phenomenon of sound passing through the wall and further propagating, and the setting of the dry sound-absorbing cavities 8 further reduces the size of sound penetration, thereby achieving a highly efficient noise reduction effect.

[0024] The horizontal splicing assembly includes a connecting frame 10 and a fitting plate 11 set on the outer wall 2, and two first bolts 13 penetrating the connecting frame 10 and the fitting plate 11; the noise reduction plate 7 has multiple sound-absorbing cavities 8 inside; the first bolts 13 are threadedly connected to the inner wall 1; the connecting frame 10 has a rectangular groove, and an elastic sealing gasket 12 is set inside the groove; the fitting plate 11 is embedded inside the groove; when horizontally splicing the outer wall 2, the fitting plate 11 on one side of the outer wall 2 can be aligned with the rectangular groove of the connecting frame 10 on the other side of the outer wall 2 and inserted; the elastic sealing gasket 12 ensures the tightness of the connection; then the first bolts 13 are threaded through the connecting frame 10 and the fitting plate 11 until they are threadedly engaged with the inner wall 1. This not only plays a role in positioning and fixing the wall installation, but also avoids the disadvantage of gaps at the connection of the outer wall 2, ensuring the performance of the wall panel and having good practicality.

[0025] Example 2

[0026] like Figure 1 and Figure 4As shown, this embodiment proposes an energy-saving and noise-reducing wall structure.

The second bolts 17 are threadedly connected to the inner wall 1. The locking block 15 is located between the upper and lower outer walls 2 and abuts against each other. The pressure plate 16 abuts against the outer wall 2. The installation plate 14 is provided with a plurality of countersunk holes 18, and the second bolts 17 are located inside the countersunk holes 18.

[0027] The mounting plate 14 and the pressure plate 16 are provided with multiple linearly distributed reinforcing ribs 19.

[0028] In this embodiment, when using the installation assembly to reinforce the outer wall 2, the clip 15 is first inserted into the gap between the upper and lower outer walls 2 to fill it until the pressure plates 16 on both sides of the installation plate 14 are pressed onto the outer walls 2 on both sides. Then, the second bolt 17 is screwed into the countersunk hole 18, thus completing the reinforcement installation of the outer wall 2. The reinforcing ribs 19 ensure the structural strength of the pressure plate 16 and guarantee the service life of the structure. The operation is simple and convenient.
