The utility model AB board composite insulation strip also includes a tie 5, which passes vertically through the inner insulation board 2 and has its two ends fixed between the autoclaved aerated concrete board 1 and the outer insulation board 3, respectively. There are multiple tie ties 5 and they are regularly arranged along the board surface, and the number of tie ties 5 is proportional to the size of the board width.
[0029] By compounding the AB board on the outer wall of the autoclaved aerated concrete board 1, a higher comprehensive performance of thermal insulation and fire protection can be achieved. By adding a tie member 5 between the autoclaved aerated concrete board 1 and the outer insulation board 3, the overall strength of the insulation strip is improved, and the anti-falling effect is good.
[0030] In a specific implementation of this embodiment, Figure 1 As shown, the inner insulation board 2 is specifically made of molded polystyrene board, graphite polystyrene board, extruded polystyrene board, or graphite extruded board.
