Fastener type self-decoration composite heat insulation high layer dwelling building module and its construction method

The invention discloses a snap-in self-ornamental composite insulated building module used by a high-rise building and a building construction method for the same. The building module mainly comprisesan external walling module, an internal walling module and a clamping piece. The building construction method comprises the following steps that: a). reinforcing steel bars of a ground ring beam, a shear wall and a constructional column are bound; b). the external walling module and the internal walling module form hollow walling through the clamping piece and a draw-in gear by means of clamping,and the shear wall and the constructional column are positioned inside the hollow walling; c). wires are bound on the reinforcing steel bars to form outlines of the shear wall and the constructionalcolumn; d). concrete placement is respectively performed to form the shear wall and the constructional column; e). fire-retardant foam particles and foam concrete are used for mixed placement of the hollow walling to complete f
