[0036] In order to make the technical problems, technical solutions, and beneficial effects solved by this application more clearly understood, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application; it is obvious that the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of this application.

[0037] Example 1

[0038] 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.

[0039] 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.

[0040] 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. Figure 2-3 The local resonance frame structure 12 is arranged inside the cylindrical steel cage 11, and the concrete outer layer 13 is wrapped around the outer side of the cylindrical steel cage 11; preferably, the concrete outer layer 13 is cast using C30 diluted concrete.

[0041] 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.

[0042] 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 block of silicone rubber material; a phononic crystal plate is shared by two adjacent square column frame-type phononic crystals.

[0043] In this embodiment 1, the crystal configuration and action mechanism of the local resonance framework structure 12 are as follows:

[0044] The metal body 121 in the local resonance frame structure 12 serves as a hard material, and the rubber body 122 serves as a soft material; the rubber body, which serves as a soft material, is used to periodically replace and fill the metal body, which serves as a hard material, to form a resonance unit, and then the structure is spliced ​​to form 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, which serves as a soft material; and for bending vibration, it is only explained by the vibration of the rubber body, which serves as a soft material, that is, using a simplified "base-spring-mass block" model; wherein the metal body, which serves as a hard material, is equivalent to the base, and the rubber body, which serves as a soft material, is equivalent to the spring and the mass block.

[0045] 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. The elastic waves within the band gap frequency range will be 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 structure 12 in the wall connecting column 1, it can play a role in noise reduction, thereby improving the sound insulation at low frequencies while improving the overall sound insulation effect, improving user comfort, and enriching building functions.

[0046] 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.

[0047] The splicing end of the prefabricated wall panel 10 is provided with a splicing groove 6, which is a rectangular opening groove. Figure 4 As shown; wherein, the opening of the splicing groove 6 is connected with the splicing end face of the prefabricated wall panel 10, the bottom of the splicing groove 6 extends toward the thickness center square of the prefabricated wall panel 10, and the long axis direction of the splicing groove 6 is vertically arranged.

[0048] When two adjacent prefabricated wall panels 10 are spliced, the wall connecting column 1 is vertically arranged at the center of the vertical joint of the two adjacent prefabricated wall panels 10; the first embedded body 2 is installed in the splicing groove 6 of one of the prefabricated wall panels 10, and the second embedded body 3 is installed in the splicing groove 6 of the other prefabricated wall panel 10; specifically, one side of the first embedded body 2 is connected to one side of the wall connecting column 1, and the other side of the first embedded body 2 is embedded in the splicing groove 6 of one of the prefabricated wall panels 10; one side of the second embedded body 3 is connected to the other side of the wall connecting column 1, and the other side of the second embedded body 3 is embedded in the splicing groove 6 of the other prefabricated wall panel 10.

[0049] The centers of the first embedded body 2 and the second embedded body 3 are both provided with reserved square holes 7, the reserved square holes 7 are vertically arranged, and the center lines of the reserved square holes 7 coincide with the vertical center lines of the first embedded body 2 or the second embedded body 3; the top wall of the splicing groove 6 is provided with a square hole, and the square hole is located directly above the reserved square hole 7; wherein, the upper end of the square hole is connected with the top end of the prefabricated wall panel 10, and the lower end of the square hole is connected with the top wall of the splicing groove 6, and is connected with the upper end of the reserved square hole 7, that is, the reserved square hole 7 and the square hole are connected up and down to form a vertical channel; a through dowel is vertically inserted in the center of the vertical channel, and post-cast concrete is poured into the vertical channel; wherein, the post-cast concrete is wrapped around the through dowel.

[0050] In this embodiment 1, by setting a splicing groove 6 at the splicing end of the prefabricated wall panel 10, the first embedded body 2 or the second embedded body 3 is installed in the splicing groove to achieve a vertical dry connection between the connected prefabricated wall panels 10; a reserved square hole 7 is set in the center of the first embedded body 2 and the second embedded body 3, a square hole is set on the top wall of the splicing groove, and the reserved square hole and the square hole are connected to each other up and down to form a vertical channel. By setting a through-reinforcement bar in the vertical channel and pouring post-cast concrete, the rigidity and strength of the vertical joints of adjacent prefabricated wall panels 10 are effectively reinforced, thereby improving the integrity of the wall structure.

[0051] In this embodiment 1, weather-resistant sealant is poured into the joint between the wall connecting column 1 and the prefabricated wall panel 10, and filling mortar is set on the surface of the joint between the wall connecting column 1 and the prefabricated wall panel 10; by injecting weather-resistant sealant and filling mortar at the vertical joints, the structure not only ensures strength but also takes into account the waterproof function, enhances the safety and stability of the structure, improves the density of the joints and enhances the waterproof effect of the structure.

[0052] Construction process:

[0053] The vertical connection device for prefabricated wall panels described in Example 1 is constructed as follows:

[0054] Step 1: Production of prefabricated wall panels

[0055] First, prefabricated formwork is assembled; prefabricated steel formwork is used for the joint grooves on the prefabricated wall panels, and PVC square tubes are set as formwork at the reserved square holes; then, 20mm thick C30 fine stone concrete is poured on the bottom layer; then, the processed transverse ribs and longitudinal ribs are placed in the formwork; after all are placed, C30 fine stone concrete is poured, and then leveled and plastered. After prefabrication, standard curing is carried out. When the strength reaches the required level, the formwork and PVC square tubes are removed, and the prefabricated wall panel 10 is formed.

[0056] Step 2: Production of vertical connection devices for prefabricated wall panels

[0057] First, the metal body and the rubber body are arranged alternately to form a square column frame type phononic crystal with an 8×8×8 unit cell periodic arrangement; then, several square column frame type phononic crystals are arranged vertically in sequence to form a local resonance frame structure; secondly, the templates of the wall connection column, the first embedded body and the second embedded body are assembled; wherein, PVC square tubes are set at the reserved square holes in the first embedded body and the second embedded body; then, the processed columnar steel cage is placed in the template, and then the processed local resonance frame structure is placed inside the columnar steel cage; after the placement is completed, C30 fine stone concrete is poured, and then leveled and plastered. After prefabrication, standard curing is carried out. When the strength reaches the requirement, the template and PVC tube are removed to form a prefabricated wall panel vertical connection device.

[0058] Step 3: Connection between the vertical connection device of the prefabricated wall panel and the prefabricated wall panel

[0059] Lay out the lines and locate the wall, hoist and fix the first prefabricated wall panel, lift the vertical connection device of the prefabricated wall panel, determine the position of the wall connection column, extend the first embedded body of the vertical connection device of the prefabricated wall panel into the fixed wall, and align it with the square hole reserved on the upper part; then lift the second prefabricated wall panel, determine the position, align the splicing groove of the second prefabricated wall panel with the second embedded body, push the prefabricated wall panel, so that the second embedded body extends into the splicing groove of the second prefabricated wall panel, and aligns it with the square hole reserved on the upper part; then, insert two through-rebars into the reserved holes on both sides respectively, and partially pour concrete in the holes to complete the connection between the vertical connection device of the prefabricated wall panel and the prefabricated wall panel.

[0060] Step 4: Seam processing

[0061] After the splicing is completed, inject weather-resistant glue directly into the vertical joints, and then use filling mortar and leveling.

[0062] The prefabricated wall panel vertical connection device described in Example 1 of the present invention, while ensuring the connection, introduces a local resonance frame structure with a phononic crystal structure, which can play a role in noise reduction, can improve the sound insulation at low frequencies while improving the overall sound insulation effect, improve user comfort, and enrich the building function; secondly, the local resonance frame structure adopts a phononic crystal structure, which can play a vibration reduction role, and achieve the vibration reduction effect by suppressing the propagation of seismic waves, thereby improving the structural reliability and increasing the stability of the structure under earthquakes.

[0063] In this embodiment 1, a large amount of on-site wet work can be avoided; compared with other forms of dry connection methods, there is no need to connect the connectors and embedded parts through bolts or welding, which improves the efficiency of installation and disassembly; secondly, it can achieve the effect of no formwork, which can greatly improve construction efficiency and save construction resources while ensuring structural strength; the use of inserted reinforcement and local post-cast concrete at the connection greatly strengthens the rigidity and strength of the structural connection.

[0064] Example 2

[0065] The structure and principle of the prefabricated wall panel vertical connection device provided in this embodiment 2 are basically the same as those of the prefabricated wall panel vertical connection device described in the above embodiment 1. The difference is that the upper end surface of the prefabricated wall panel is provided with a positioning dowel 8, and the lower end surface of the prefabricated wall panel is provided with dowel pre-reserved holes 9, as shown in the attached figure. Figure 4 As shown; wherein, one end of the positioning dowel 8 is embedded in the upper end face of the next layer of prefabricated wallboard, and the other end of the positioning dowel 8 is inserted into the dowel reserved hole 9 on the lower end face of the previous layer of prefabricated wallboard.

[0066] It should be noted that when the prefabricated wall panels 10 are produced, embedded dowels are set on the upper end of the wall panels and extend out of the template as positioning dowels 8; a PVC round tube of the same size as the positioning dowel is set at the lower end of the wall panels as a dowel reserved hole 9.

[0074] Afterwards, through-rebars are installed in the first vertical channel and the second vertical channel respectively, and post-cast concrete is poured through the top of the square holes.
