This material can not only improve the overall aesthetics and thermal insulation performance of the building, but also effectively reduce construction time and cost. With the acceleration of urbanization, the demand for integrated exterior wall panels has gradually increased, becoming one of the important development directions in the construction field. The integrated exterior wall panels commonly seen on the market are mainly assembled from prefabricated components, have good weather resistance and wind pressure resistance, and can meet the needs of different architectural styles and functions.

[0007] By adopting the above technical solution, after the unit wall panels are inserted into the shear wall through multiple internal threaded tubes, multiple unit wall panels are horizontally connected to form an external wall panel, and multiple external wall panels are vertically connected to form an external wall integrated panel, so as to realize the rapid assembly of the external wall integrated panel. A first connecting strip is provided between two vertically adjacent unit wall panels, and the first connecting strip is slidably connected to the two unit wall panels in the horizontal direction, and a second connecting strip is provided between two horizontally adjacent unit wall panels, and the second connecting strip is slidably connected to the two unit wall panels in the vertical direction, so as to ensure that the connection between the unit wall panels is tight and flexible, and facilitate the rapid assembly and connection of multiple unit wall panels on site. After the external wall integrated panel is spliced, concrete is injected between the external wall integrated panel and the shear wall to form a concrete layer, and the external wall integrated panel is fixed to the shear wall after the concrete layer solidifies. In the present application, when the external wall integrated panel is installed, it is not necessary to open bolt holes in the external wall integrated panel, which reduces the risk of leakage of the external wall integrated panel and improves the installation efficiency of the external wall integrated panel.

[0008] Preferably, both vertical ends of the unit wall panel are provided with first dovetail slide grooves arranged in the horizontal direction; the first connecting strip includes two symmetrically connected first dovetail slide rails, and the two first dovetail slide rails are respectively located in the two first dovetail slide grooves.

[0009] By adopting the above technical solution, the rapid assembly between the unit wall panels is facilitated, so that the unit wall panels are connected together in the vertical direction, thereby improving the integrity and stability of the entire external wall integrated panel.

[0010] Preferably, a first elastic plate is connected between the two first dovetail slide rails.

[0011] By adopting the above technical solution, the first elastic plate enables the distance between the two first dovetail slide rails to be fine-tuned, so that when the two unit wall panels are misaligned, the first connecting strip can still connect the two unit wall panels together. At the same time, the first elastic plate can also absorb and disperse external impact force, reduce the damage to the unit wall panels caused by external vibration, and extend the service life.

[0016] Preferably, a steel cage is provided on the inner surface of the unit wall panel.

[0017] By adopting the above technical solution, after the initial positioning between the unit wall panel and the shear wall, concrete needs to be injected between the unit wall panel and the shear wall to form a concrete layer to achieve the final fixation of the unit wall panel.
