The invention belongs to the technical field of building
engineering and particularly relates to a polyphenyl core panel composite heat insulation external wall panel. The polyphenyl core panel composite heat insulation external wall panel is characterized in that the front side and the back side of a polyphenyl core panel in the length direction are respectively provided with
linear longitudinal steel bar grooves, the polyphenyl core panel is provided with annular
steel bar grooves in the width direction, linear steel bars and annular steel bars are arranged in the longitudinal
steel bar grooves and the annular steel bar grooves, the linear steel bars and the annular steel bars form a steel bar mesh cage, the polyphenyl core panel is surrounded in the steel bar mesh cage, steel
wire mesh sheets are arranged on the steel bar mesh cage, light-weight heat insulation
mortar wraps the steel
wire mesh sheets and the steel bar mesh cage to from a light-weight heat insulation
mortar case layer, the polyphenyl core panel is arranged in the light-weight heat insulation
mortar case layer, a connecting iron element is welded with the steel bar mesh cage, and the end part of the connecting iron element is exposed out or extends out of the light-weight heat insulation mortar case layer. The polyphenyl core panel composite heat insulation external wall panel has the advantages that the industrial production can be adopted, the panel case light-weight heat insulation mortar raw materials adopt the electronic metering and the mechanical grouting, the grouting pressure is monitored through a computer, the
electronic temperature control is adopted, and the panel specification size and the thickness of each layer of the panel are enabled to be respectively in the control requirement range.
