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.
