Because the anchoring parts are arranged in the thickness direction of the heat insulation decorative plate, and at least 2 anchoring parts are required to be placed on each plate, a large number of hot (cold) bridges exist in the heat insulation system outside the building, and the energy consumption is increased. On the other hand, the support of the heat insulation plate is basically in a combined form of two steel plates, the two steel plates are provided with the long circular holes, the heat insulation plate is suitable for heat insulation plates with different thicknesses by adjusting the relative positions of the long circular holes, and the long circular holes can only adjust the distance and cannot generate pretightening force, so that the heat insulation plate cannot become an effective stress body with a base layer wall body, and cannot play a corresponding protection role.
When the heat preservation is decorated the intergral template and is applied to passive form low energy consumption building, how solve hot (cold) bridge problem, how produce the pretightning force when the heated board of adaptation different thickness is the difficult problem that an urgent need be solved of prefabricated outer wall of assembled, passive form low energy consumption building.
