[0002] In the current construction industry, the structural form of wall ties used for building exterior frames is single, and steel pipes are generally embedded in concrete structures and then connected using rotating fasteners.

[0003] However, this method has a major drawback, namely, the protruding structure of the wall connecting parts requires a hole to be reserved for post-building in order to ensure the safety of the outer wall during wall construction. The later filling of the hole not only wastes materials, but also consumes time and labor, and is prone to cause seepage and leakage in the main structure. There are also some wall connecting parts that cannot be avoided from conflicting with the structure, and they will be removed in advance, increasing safety hazards on site. At the same time, steel pipes need to be removed when the wall connecting parts are removed, which has low work efficiency. To this end, the utility model proposes a pre-buried attached wall connecting device to solve the above problems. Utility Model Content
