DETAILED DESCRIPTION

[0038] The present invention is further described in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0039] Embodiment 1:

[0040] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An embodiment of the present invention provides an assembled wall with phononic crystals, comprising a plurality of wall panels 1 arranged in sequence along a horizontal direction, a connecting plate 2 is provided between two adjacent wall panels 1, grooves are provided on both sides of the connecting plate 2, and the two adjacent wall panels 1 are respectively clamped in the grooves on both sides of the connecting plate 2; a first steel cage 7 is provided in the connecting plate 2, and a vertical phononic crystal frame is provided in the first steel cage 7, and the vertical phononic crystal frame is arranged along the height direction of the wall panel 1, and the vertical phononic crystal frame includes an inner ring frame 9 and an outer ring frame 8, and the inner ring frame 9 is sleeved on the inner side of the outer ring frame 8 and the two are connected; the inner ring frame 9 and the outer ring frame 8 are both composed of hard material parts and soft material parts arranged periodically.

[0041] In some embodiments of the present application, a phononic crystal is a new type of artificially designed functional material, the core feature of which is a periodically arranged structure that can regulate the propagation of sound waves, elastic waves or vibration waves. Typically, a phononic crystal is composed of two or more materials with different elastic properties arranged periodically (such as metals, plastics, rubbers, etc.) to form a one-dimensional, two-dimensional or three-dimensional structure. Phononic crystals have the advantages of noise reduction, vibration suppression and thermal management. Phononic crystals are periodic composite materials or structures with elastic wave band gaps, and vibrations within the band gap frequency range cannot be transmitted through phononic crystals. In recent years, phononic crystals have been widely used in the study of basic elastic structures.

[0042] In some embodiments of the present application, Figure 1 As shown, the connecting plate 2 is a rectangular plate structure, and the grooves on both sides of the connecting plate 2 are rectangular grooves. Among the two wall panels 1 arranged in the horizontal direction, the right end of the wall panel 1 on the left is clamped in the rectangular groove on the left side of the connecting plate 2, and the left end of the wall panel 1 on the right is clamped in the rectangular groove on the right side of the connecting plate 2.

[0043] In some embodiments of the present application, Figure 3 As shown, the first steel cage 7 is arranged in the middle position of the connecting plate 2, and the vertical phononic crystal frame is a cylindrical frame structure.

[0044] In some embodiments of the present application, Figure 3 As shown, the first steel cage 7 is a rectangular frame structure, and the vertical phononic crystal frame is nested in the first steel cage 7 .

[0045] In some embodiments of the present application, the inner annular frame 9 is provided with a plurality of hard material pieces along the circumference, and a soft material piece is sandwiched between two adjacent hard material pieces. In this way, the hard material pieces and the soft material pieces can be periodically arranged along the circumference of the inner annular frame 9.

[0046] In some embodiments of the present application, the outer annular frame 8 is provided with a plurality of hard material pieces along the circumference, and a soft material piece is sandwiched between two adjacent hard material pieces. In this way, the hard material pieces and the soft material pieces can be periodically arranged along the circumference of the outer annular frame 8.

[0047] In some embodiments of the present application, Figure 3 As shown, a connecting piece is further provided between the inner annular frame 9 and the outer annular frame 8, and the connecting piece is provided along the radial direction of the inner annular frame 9, and one end of the connecting piece is connected to the inner annular frame 9, and the other end is connected to the outer annular frame 8. There are a plurality of connecting pieces, and the plurality of connecting pieces are evenly distributed along the circumference of the inner annular frame 9.

[0048] In some embodiments of the present application, the hard material parts may be metal parts such as iron parts and copper parts, and the soft material parts may be rubber parts, silicone parts, etc.

[0049] In some embodiments of the present application, the vertical phononic crystal frame is composed of two materials, hard and soft, the main body of which is hard material iron and copper, and the soft material silicone rubber is periodically used to replace and fill it, and the two materials are periodically combined to form a resonance unit, so as to construct a local resonance phononic crystal frame structure. In longitudinal vibration, the entire structure can participate in the vibration and the main vibration is concentrated on the soft material silicone rubber, but for bending vibration, only the soft material vibrates, which can be explained by the simplified model of "base-spring-mass block", in which the hard material iron and copper can be equivalently regarded as the base, and the soft material silicone rubber is equivalent to the spring and mass block. On the other hand, from the overall perspective of the building structure, the connecting components and walls become scatterers in the periodic cells. When an earthquake is induced, when the elastic wave propagates to the seismic structure, the scatterer is induced to resonate. At a specific frequency, the seismic structure has a negative effective mass density, thereby generating a band gap. The elastic wave within the band gap frequency range will be prohibited from propagating when passing through this infinite periodic structure, thereby suppressing the propagation of seismic waves and achieving the effect of vibration reduction.

[0050] In the above scheme of the present application, the prefabricated wall includes a plurality of wall panels 1 arranged in sequence along the horizontal direction, a connecting plate 2 is provided between two adjacent wall panels 1, grooves are provided on both sides of the connecting plate 2, and the two adjacent wall panels 1 are respectively clamped in the grooves on both sides of the connecting plate 2; a first steel cage 7 is provided in the connecting plate 2, a vertical phononic crystal frame is provided in the first steel cage 7, the vertical phononic crystal frame is arranged along the height direction of the wall panel 1, the vertical phononic crystal frame includes an inner ring frame 9 and an outer ring frame 8, the inner ring frame 9 is sleeved on the inner side of the outer ring frame 8 and the two are connected; the inner ring frame 9 and the outer ring frame 8 are both composed of hard material parts and soft material parts arranged periodically. By adopting this structure, when a first steel cage 7 and a vertical phononic crystal frame are provided in the connecting plate 2, the overall stability of the connecting plate 2 can be improved, wherein the vertical phononic crystal frame can play a noise reduction role, thereby improving the sound insulation effect of the connecting plate 2 and improving the user's comfort. In addition, the vertical phononic crystal frame can also play a vibration reduction role, achieving the vibration reduction effect by suppressing the propagation of seismic waves, thereby improving the overall reliability of the prefabricated wall.

[0051] In addition, the above connection structure of the present application is a dry connection, which avoids wet work on site. Compared with other forms of dry connection, the above connection structure of the present application eliminates the process of connecting the connecting parts and the embedded parts by bolts or welding, which improves the efficiency of installation and disassembly.

In this way, the stability of the outer ring frame 8 can be improved. In addition, since the shear force on the upper part is greater than that on the lower part when the assembled shear wall is connected, the upper part of the outer ring frame 8 is destroyed earlier than the lower part. When this structure is adopted, the hard material members used in the upper part and the lower part of the outer ring frame 8 are different, so that the density difference between the upper part of the outer ring frame 8 and the lower part is greater, so that the shock absorption effect of the outer ring frame 8 is better.

[0053] In some embodiments of the present application, Figure 5As shown, the hard material part at the upper part of the outer annular frame 8 is a copper layer 11, and the soft material part at the upper part of the outer annular frame 8 is a first rubber layer 12, and the copper layer 11 and the first rubber layer 12 are alternately distributed. The hard material part at the lower part of the outer annular frame 8 is an iron layer 13, and the soft material part at the lower part of the outer annular frame 8 is a second rubber layer 14, and the iron layer 13 and the second rubber layer 14 are alternately distributed.

With this structure, the stability of the inner ring frame 9 can be improved. Moreover, a local resonance can be formed between the inner ring frame 9 and the outer ring frame 8, thereby enhancing the shock absorption effect and strength of the connecting plate 2, so as to achieve the effect of "strong connection of weak components".

[0055] In some embodiments of the present application, Figure 6 As shown, the hard material part of the inner annular frame 9 is a copper layer 11, and the soft material part of the inner annular frame 9 is a first rubber layer 12, and the copper layer 11 and the first rubber layer 12 are alternately distributed.
