Assembly type building wall connecting device convenient to install

The invention relates to the field of building assembly, in particular to a convenient-to-install assembly type building wall connecting device which comprises prefabricated parts, connecting grooves are formed in the connecting faces between the prefabricated parts, a plurality of steel bars are fixedly installed in the connecting grooves, and electromagnetic connecting assemblies are arranged in the connecting grooves. After the electromagnetic connecting assembly is electrified, steel bars on the two prefabricated parts can be automatically connected, the prefabricated parts of the prefabricated building can be rapidly connected through the design, installation and operation are easy and convenient, the effect is high, due to the fact that the connecting structure is located in the connecting groove and matched with smearing of cement paste, the connecting position can be perfectly hidden in the wall, and the construction efficiency is improved. And the wall body is more beautiful. 本发明涉及建筑装配领域，具体涉及一种便于安装的装
