DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by this application clearer, the technical solutions in the embodiments of this application will be described clearly and completely in combination with the drawings in the embodiments of this application; obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Example 1 This embodiment 1 provides a prefabricated wall panel vertical connection device, which is arranged between the vertical joints of two adjacent prefabricated wall panels; Figure 1-3 As shown, the prefabricated wall panel vertical connection device includes a wall connection column 1, a first embedded body 2 and a second embedded body 3.

[0022] The wall connecting column 1 is vertically arranged between two adjacent prefabricated wall panels 10; the first embedded body 2 is vertically arranged on the first side of the wall connecting column 1, and the first embedded body 2 is located in the middle of the first side of the wall connecting column 1; wherein the length of the first embedded body 2 is less than the vertical height of the wall connecting column 1; the second embedded body 3 is vertically arranged on the second side of the wall connecting column 1, and the second embedded body 3 is located in the middle of the second side of the wall connecting column 1; wherein the length of the second embedded body 3 is less than the vertical height of the wall connecting column 1.

[0023] In this embodiment 1, the wall connecting column 1 includes a columnar steel cage 11, a local resonance frame structure 12 and a concrete outer layer 13, as shown in the attached Figure 2-3 The local resonance frame structure 12 is arranged inside the columnar steel cage 11, and the concrete outer layer 13 is wrapped around the outside of the columnar steel cage 11; preferably, the concrete outer layer 13 is cast by C30 diluted concrete.

[0024] Specifically, the local resonance frame structure 12 includes a plurality of square column frame type phononic crystals, which are arranged vertically in sequence; each of the square column frame type crystals is a hollow rectangular parallelepiped frame structure, and the square column frame type phononic crystal is formed by splicing six phononic crystal plates.

[0025] Each of the phononic crystal plates includes a metal body 121 and a rubber body 122 periodically distributed in the metal body 121; wherein the metal body 121 is a metal plate structure, and the rubber body 122 is used to periodically replace and fill the metal body 121, so that the metal body 121 and the rubber body 122 are periodically combined to form a resonance unit; preferably, the metal body 121 is made of an iron plate, and the rubber body 122 is a silicone rubber material block; a phononic crystal plate is shared by two adjacent square column frame-type phononic crystals.

[0026] In this embodiment 1, the crystal configuration and action mechanism of the local resonance framework structure 12 are as follows: The metal body 121 in the local resonance frame structure 12 is used as a hard material, and the rubber body 122 is used as a soft material; the rubber body as a soft material is used to periodically replace and fill the metal body as a hard material to form a resonance unit, and then the splicing structure forms a local resonance frame structure; when facing longitudinal vibration, the entire local resonance frame structure 12 can participate in the vibration, and the main vibration is concentrated on the rubber body as a soft material; and for bending vibration, it is only explained by the vibration of the rubber body as a soft material, that is, the simplified model of "base-spring-mass block" is adopted; wherein, the metal body as a hard material is equivalent to the base, and the rubber body as a soft material is equivalent to the spring and the mass block.

[0027] From the overall perspective of the building structure, the wall connecting column 1 acts as a scatterer in a periodic cell. When an earthquake is induced, when the elastic wave propagates to the wall structure including the wall connecting column 1, the scatterer is induced to resonate. At a preset frequency, the wall structure has a negative effective mass density, thereby generating a band gap. Elastic waves within the band gap frequency range are prohibited from propagating when passing through the local resonance frame structure 12 with an infinite period, thereby suppressing the propagation of seismic waves and achieving a vibration reduction effect. Similarly, by introducing the local resonance frame 12 in the wall connecting column 1, it can play a role in noise reduction, so as to improve the overall sound insulation effect while increasing the sound insulation at low frequencies, thereby improving user comfort and enriching building functions.

[0028] In this embodiment 1, the first embedded body 2 and the second embedded body 3 are cast and formed simultaneously with the concrete outer covering 13 in the wall connecting column 1; preferably, the first embedded body 2 and the second embedded body 3 are cast and formed by using C30 fine stone concrete.
