The invention belongs to the technical field of constructional
engineering and discloses a composite heat-insulating superimposed sheet integrated with a concrete body structure. The sheet is characterized in that interface agent protective
layers are arranged on both sides of a
polystyrene board, bidirectional high-strength steel wires which are inserted obliquely are distributed inside the
polystyrene board, and a single side of the
polystyrene board is covered by and welded with a steel
wire mesh, accordingly, a heat-insulating plate with the whole
welding steel
wire frame is formed, wherein obliquely-inserted steel wires penetrate through the polystyrene board. The steel
wire mesh is wrapped in a light composite concrete layer, the light composite concrete layer is combined with an extruded sheet through an interface agent to form the heat-insulating plate, an
anchor bolt hole is arranged on the heat-insulating plate, a counter bored hole is arranged on the light composite concrete layer corresponding to the
anchor bolt hole, an
anchor bolt is arranged inside the anchor bolt hole, and one end of the anchor bolt extends out of the extruded sheet and the interface agent protective layer and is locked by a nut. The composite heat-insulating superimposed sheet is good in
fire safety and capable of simplifying construction procedures, accelerating the construction progress, reducing building costs, achieving industrial production, guaranteeing the quality of all aspects and avoiding hidden quality dangers, such as empty drums, cracks,
water seepage and falling-off, caused by complicated
operating procedures to the maximum extent.
