The utility model relates to a prefabricated wall connection technology field discloses a horizontal absolutely dry formula connection structure of wall based on assembly type structure wall. Because this connection structure is the cooperation of directly adopting connecting piece and bolt to be realized the absolutely dry formula that the polylith prefabricated the wall body and is connected, consequently, can save on -the -spot wet trade in assembly process, thereby shorten construction cycle and reduce the cost of labor, simultaneously still can be because of having saved the wet trade template, on -the -spot concrete and some anchor reinforcing bars, make material cost also reduce by a wide margin, and then can break through the obstacle that assembly type structure development on current phase faces in the aspect of two construction cycle and construction cost, promote building industrialization's development in an all -round way. Furthermore, connection structure still has strong, the easy equipment of steadiness and dismantles, does benefit to advantages such as environmental protection and simple structure, be convenient for practical application and popularization.
