Fabricated outer wall with waterproof abutted seams

The invention provides an assembled outer wall with waterproof abutted seams, which is characterized in that a wall body structure is formed by splicing a plurality of prefabricated wall bodies, transverse seams and vertical seams are formed among the prefabricated wall bodies, the transverse seams and the vertical seams are not straight structures, the transverse seams are provided with inclined rabbets with high inner parts and low outer parts, namely, the transverse seams are provided with inclined sections, and when water enters the transverse seams, the water enters the transverse seams, so that the water is prevented from entering the transverse seams; due to the action of gravity, the water cannot flow upwards and cannot reach the inner surface of a wall body and enter a room; a condensation cavity is formed in the middle of the vertical joint, the width of the condensation cavity is larger than the width of other positions of the vertical joint, water vapor enters the condensation cavity and then ends
