The invention discloses a manufacturing and installation method for a built-in flange and an air hose for building construction and an application layer structure. The method includes the following steps that (1) the air hose and the built-in flange are formed, etc., the air hose and the built-in flange are manufactured according to the dimension requirements of a design drawing; (2) flange riveting is conducted, etc., the built-in flange is fixed to the air hose in a riveted mode; and (3) edge turning is conducted, etc., the edge of the air hose riveted with the flange is turned inwards. Air hoses can be connected when complex pipelines are densely distributed and no construction space exists for air hose connection. By means of the construction method with the built-in flange connected with the air hose, air hose structures connected through built-in flanges can be manufactured, the situation that air hoses cannot be connected in a narrow construction space is avoided, and continuous progress of the whole project is guaranteed.
