The building body comprises a wall body, outer decorative blocks and first connecting strips; the outer decorative blocks are mounted on the wall body by the first connecting strips, wherein mounting grooves with T-shaped cross sections are formed in the outer wall of the wall body, and the cross sections of the first connecting strips are in a I shape; one wings of the first connecting strips are connected into the mounting grooves in an inserted mode, and the other wings of the first connecting strips protrude out of the wall body; first protruding strips and first strip-shaped grooves are correspondingly arranged on the opposite two side surfaces of the outer decorative blocks, the first protruding strips are located outside the first strip-shaped grooves, and the first protruding strips and the first strip-shaped grooves penetrate through the two side surfaces of the outer decorative blocks up and down; and the other wings of the first connecting strips are connected into the first strip-shaped grooves of every two adjacent outer decorative blocks in an inserted mode. The outer decorative blocks are connected with the wall body by connecting clamping strips in a clamping mode, and the combination of the outer decorative blocks and the wall body is more firm, the hollowing and cracking of the outer decorative blocks bonded by mortar in the prior art are avoided, and keels are not used, so that the installation is convenient, construction is convenient, and an engineering application effect is good.

The invention discloses a prefabricated bay window and a connection node between the prefabricated bay window and a main body of a steel structure. The prefabricated bay window comprises two symmetrically arranged vertical pipes; a horizontal pipe, a bay window bottom plate and a bay window top plate are horizontally arranged between the two vertical pipes in sequence from bottom to top; one end of the bay window bottom plate is erected on the horizontal pipe; the other end of the bay window bottom plate extends in a direction away from the vertical pipes; one end of the bay window top plate is located between the two vertical pipes; the other end of the bay window top plate extends in a direction away from the vertical pipes and is flush with one end, away from the vertical pipes, of thebay window bottom plate; and the vertical pipes and the horizontal pipe are steel pipes. The prefabricated bay window is simple in structure, lighter in weight, and lower in on-site construction difficulty, the prefabricated bay window can be connected with the main body of the steel structure only through welded connection or bolted connection, local casting is not required, the installation andconstruction efficiency is high, and the prefabricated bay window can be produced in batch in a factory.
