Problems solved by technology

When the sandwich insulation board is used in ultra-low energy buildings, due to the high requirements on the insulation performance of the outer wall, the insulation layer is laid up more often, and the thickness often reaches more than 150mm, which makes the knotting of the vacuum insulation board unable to achieve structural reliability. Require

Abstract

The invention provides a wall panel, which includes a sandwich structure composed of an inner panel and an outer panel, and the inner panel, a composite thermal insulation layer and the outer panel are fixed by a heat-breaking bridge tie; the composite thermal insulation layer includes at least one layer Vacuum insulation board, the inner vacuum insulation board and the inner page board are filled with an inorganic insulation material bonding layer, and the gaps between each layer of vacuum insulation boards and the vacuum insulation board are filled with inorganic insulation material bonding layer or polyurethane insulation slurry The material bonding layer, the outer layer of the vacuum insulation board is laid with a rock wool layer, the graphite polystyrene board is laid outside the rock wool layer, the graphite polystyrene board is set with a thin layer of thermal insulation mortar, and the thin layer of thermal insulation mortar is laid with basalt fiber mesh cloth, basalt The fiber mesh cloth is tightly attached to the inner side of the outer panel, and the seam of the graphite polystyrene board is sealed with a waterproof and breathable membrane. The thin high-insulation-performance sandwich wallboard used for prefabricated ultra-low energy consumption buildings has the advantages of greatly reducing thickness, high insulation performance, reducing structural cost, and saving land and energy.

Description

technical field [0001] The invention relates to an ultra-low energy consumption building structure, in particular to a thin sandwich wallboard with high thermal insulation performance used for an assembled ultra-low energy consumption building. Background technique [0002] Sandwich insulation board is a form of exterior wall panel commonly used in prefabricated buildings. When the sandwich insulation board is used in ultra-low energy buildings, due to the high requirements on the insulation performance of the outer wall, the insulation layer is laid up more often, and the thickness often reaches more than 150mm, which makes the knotting of the vacuum insulation board unable to achieve structural reliability. Require. At the same time, the thick insulation layer also occupies the usable area of ​​the building. Therefore, developing a high-insulation performance wall panel to reduce the thickness of the insulation layer is a key technical problem to be solved in the developm...
