Side elevation system of aluminum alloy house

The invention relates to a side elevation system of an aluminum alloy house. Four aluminum alloy vertical columns are arranged on a side elevation at intervals, The portions, in the middle of the height position of the side elevation, of the four aluminum alloy vertical columns are provided with aluminum alloy beams in a connected mode, and then a bottom layer structure and a secondary layer structure of the aluminum alloy house are formed. An aluminum alloy balcony column is arranged on the outermost layer of the bottom layer, and a bottom layer auxiliary room space and a secondary layer balcony are formed through the installed aluminum alloy beams. An aluminum alloy balcony railing is arranged on the front outer side of the secondary balcony. Aluminum alloy windows are arranged on the side elevation. A roof is composed of an aluminum alloy ring beam, roof aluminum alloy secondary beams and roof aluminum alloy purlines. The roof of the side elevation is arranged to be a slope-shaped roof. An aluminum alloy wallboard combined frame is fastened to the aluminum alloy vertical columns or the aluminum alloy beams via fasteners through an aluminum alloy combined wallboard. The side elevation is simple in arrangement structure and structural connection, short in construction period and convenient to install.
