Heat-insulating decorative fireproof partition board for exterior wall of building and construction method thereof

The invention discloses a heat-insulating decorative fireproof partition board for an exterior wall of a building and a construction method thereof. The heat-insulating fireproof decorative board adopts a heat-insulating foaming ceramic board made of fireproof materials as a fireproof partition and heat-insulating material; the heat-insulating foaming ceramic board, an enhanced panel and veneer materials form an integrated board with the functions of fire prevention, heat insulation and decoration; integrated boards are arranged along the horizontal direction of the building at intervals of certain height in a heat-insulating system for the exterior wall of the building or arranged on upper edges of window and door openings of the building to form a fire barrier, so that the flame propagation can be effectively prevented and the fire damage can be reduced; the heat-insulating fireproof decorative board is bonded with a base course wall of the building through cement mortar at first and then anchored and supported through a machine; and exterior finishes can be painted with fluorocarbon paint, fluorocarbon metallic paint, stone-like paint and the like and be matched with a conventional heat-insulating decorative board for the exterior wall of the building for use. The heat-insulating decorative fireproof partition board disclosed by the invention can be used as a fireproof construction measure to be widely applied to heat-insulating projects of exterior walls of the building industry, and has the advantages of fire prevention, heat insulation, durability, impact resistance, good decorative effect and the like. The construction method disclosed by the invention has the advantages of advanced technology, economy and rationality, convenience for assembly, low energy consumption for construction, and conformity with the national requirements of environmental protection and energy saving.
