[0036] In order to more clearly illustrate the overall concept of the present utility model, the following will be further described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0037] It should be noted that many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific implementation modes disclosed below.

[0038] As Figure 1-6 shown, the present application provides a novel connection structure for prefabricated wall panels, which mainly includes a plate edge connection structure, a plate edge strengthening structure, and a strengthening connector. Among them, the plate edge connection structure includes a groove 11 provided on the side of the prefabricated wall panel 1 and a strengthened connection part 13 provided on the outer side wall 12 of the groove 11. The grooves 11 of two adjacent prefabricated wall panels 1 are spliced correspondingly, the strengthened connection parts 13 of two adjacent prefabricated wall panels 1 are communicated correspondingly, and the plate edge connection structure further includes a slot hole 2 formed by splicing two adjacent grooves 11; the plate edge strengthening structure includes a mesh cloth 3 and a strengthening layer provided outside the strengthened connection part 13, and a filling layer 21 provided inside the slot hole 2; the strengthened connection part 13 is provided with an installation part, and the strengthening connector is connected to the installation parts of two adjacent strengthened connection parts 13 for connecting two adjacent strengthened connection parts 13 or connecting the strengthened connection part 13 with the building main structure 6.

[0039] As a preferred embodiment of the present application, the width of the strengthening connection part 13 along the width direction of the surface of the prefabricated wall panel 1 is not less than the depth of the groove 11, and the depth of the strengthening connection part 13 along the direction perpendicular to the surface of the prefabricated wall panel 1 does not exceed one-third of the thickness of the side wall 12 of the groove 11. Preferably, the width range of the strengthening connection part 13 is set to be 50-100 mm, and the depth of the strengthening connection part 13 is set to be 2-4 mm. Adopting this setting method can facilitate the setting of the strengthening connection part 13 while avoiding adverse effects on the structural strength of the groove 11 and / or the main body of the prefabricated wall panel 1 caused by the over-large size of the strengthening connection part 13.

[0040] It should be noted here that the setting method of the strengthening connection part 13 in the present application is not limited to the above examples. The above examples are only a preferred embodiment of the present application, and it can also be adaptively adjusted according to the actual wall panel specifications and dimensions on the premise of meeting the building standards. The present application does not make specific limitations on this.

[0041] In an example, referring to Figure 1 、 Figure 2 and Figure 3 shown, the strengthening connecting piece includes a first connecting card 51, the installation part is a first connecting hole 14 arranged in the strengthening connection part 13, and the first connecting holes 14 of two adjacent prefabricated wall panels 1 correspond in the height direction of the prefabricated wall panel 1. The first connecting card 51 includes a first card plate 511 and two first connecting protrusions 512 arranged on the first card plate 511. The two first connecting protrusions 512 are arranged on the same side plate surface of the first card plate 511, and the distance between the two connecting protrusions along the width direction of the prefabricated wall panel 1 is the same as the distance between the first connecting holes 14 after two adjacent prefabricated wall panels 1 are spliced. The two first connecting protrusions 512 are respectively matched with the first connecting holes 14 of two adjacent prefabricated wall panels 1. At least two first connecting holes 14 are arranged, and at least two first connecting holes 14 are arranged along the length direction of the prefabricated wall panel 1. Preferably, the first connecting hole 14 is a square hole, and the outer contour of the first connecting protrusion 512 corresponds to the inner contour of the square hole. Adopting this structure can effectively limit the rotation of the first connecting protrusion 512 relative to the first connecting hole 14, thereby restricting the longitudinal dislocation when two adjacent prefabricated wall panels 1 are spliced, and can also play a role in auxiliary positioning. Of course, the first connecting hole 14 can also be a circular hole, and the circular hole is more convenient for construction forming and further improves the construction efficiency.

[0042] Continue to refer to Figure 4 and Figure 5As shown, the reinforcing connector in this example further includes a second connecting card 52. The second connecting card 52 includes a second card plate 521, and a structural connecting protrusion 523 and a second connecting protrusion 522 oppositely arranged on both sides of the second card plate 521. The structural connecting protrusion 523 is cooperatively connected with the building main structure 6 arranged at the top or side of the prefabricated wall panel 1, and the second connecting protrusion 522 is cooperatively connected with the second connecting hole 15 arranged at the top or side of the prefabricated wall panel 1. The second connecting hole 15 is also preferably a square hole, and the staggered arrangement of the structural connecting protrusion 523 and the second connecting protrusion 522 can also limit the deflection of the prefabricated wall panel 1, thereby strengthening the stability of the connection structure between the plates and the connection structure between the plate and the building main structure 6, avoiding the cracking of the seams between the plates and / or the seams between the plate and the building main structure 6, and at the same time can also play a role in enhancing the seismic resistance. Of course, the second connecting hole 15 can also be a circular hole to further improve the construction efficiency. Continue to refer to Figure 5 As shown, preferably, the second card plate 521 includes a main body 5211 and bending parts 5212 oppositely arranged at both ends of the main body 5211. A space for accommodating the prefabricated wall panel is surrounded between the two bending parts 5212 and the main body 5211. In actual use, the two bending parts 5212 are clamped on the side plate surfaces of the prefabricated wall panel. Adopting this structure is more convenient for the positioning and installation of the second connecting card, improves the assembly efficiency, and in the actual use process, the two bending parts 5212 can provide a strengthening effect on the prefabricated wall panel in the direction perpendicular to the plate surface of the prefabricated wall panel 1, avoiding the adverse effects of the setting of the second connecting hole and the insertion of the second connecting protrusion 522 into the second connecting hole and the cooperation with the second connecting hole and / or the expansion bolt entering the second connecting hole and cooperating with the second connecting hole on the structural strength of the prefabricated wall panel.

[0043] In a preferred example, refer to Figure 6 As shown, grooves 11 are also formed at the top and bottom of the prefabricated wall panel 1, and the second connecting holes 15 are arranged in the grooves. Adopting this structure is convenient for injecting grouting materials, such as slightly expanded crack-resistant mortar, between the prefabricated wall panel 1 and the building main structures 6 at its top and bottom to seal and connect the plate seams between the prefabricated wall panel 1 and the building main structures 6 at its top and bottom, thereby improving the connection quality of the plate seams between the prefabricated wall panel 1 and the building main structures 6 at its top and bottom.

[0044] Furthermore, refer to Figure 2As shown in the figure, along the direction perpendicular to the surface of the prefabricated wall panel 1, when the novel connection structure of the prefabricated wall panel in this application is arranged between the prefabricated wall panels 1, from the inside to the outside, there are successively a filling layer 21, the side wall 12 of the groove 11, a strengthening connecting piece, a mesh cloth 3, and a strengthening layer. During the actual construction process, first, the grooves 11 of the two prefabricated wall panels 1 are aligned and spliced to form a slot hole 2, then the first connecting protrusion 512 of the first connecting card 51 is inserted into the first connecting holes 14 of the two prefabricated wall panels 1 to complete the installation of the first connecting card 51. Then, a pouring port is opened at the upper part of the slot hole 2 to pour filling material into the slot hole 2 to form a filling layer 21. Then, a mesh cloth 3 is laid on the outside of the first connecting card 51 and a strengthening layer is coated. Preferably, the filling layer 21 is a micro-expansion crack-resistant mortar layer and the strengthening layer is a plastering layer 4. It should be noted here that this application does not make specific limitations on the setting method of the filling layer 21 and the strengthening layer. It can adopt the setting method in the above example or other more different setting methods.

[0045] In summary, adopting the novel connection structure of the prefabricated wall panel in this application can effectively improve the stability of the connection structure between the prefabricated wall panels 1 and between the prefabricated wall panel 1 and the building main structure 6, thereby avoiding problems such as deviation / misalignment / loosening, which may cause the connection structure to be unstable and lead to cracking at the joints of the panel members and / or the joints between the panel and the building main structure 6, thus ensuring the construction quality. At the same time, it can also improve the seismic resistance; and in the above solution, the structure of the panel edge connection structure, the panel edge strengthening structure, and the strengthening connecting piece is simple and convenient to use together, which is beneficial to improving the construction efficiency while ensuring the construction quality.
