Assembled low-energy-consumption external wallboard

Abstract

The invention relates to an assembled low-energy-consumption external wallboard which comprises an external wallboard main body, wherein the external wallboard main body comprises two board groups inmirror symmetry and a grid cloth layer arranged between the two board groups; each board group comprises an extruded board layer, a cement foam board layer and a cement mortar plastering layer; the extruded board layer is arranged in a way of being attached to the grid cloth layer; the cement foam board layer is arranged at the side surface, backing to the grid cloth layer, of the extruded board layer; the cement mortar plastering layer is arranged at the side surface backing to the cement foam board player; edge sealing layers are arranged on the periphery of the external wallboard main body;each edge sealing layer comprises an ore rock board layer arranged in a way of being attached to the external wallboard main body; an aluminum board layer is arranged at the side surface, backing tothe external wallboard main body, of the ore rock board layer; a cement fiberboard layer is arranged at the side surface, backing to the ore rock board layer, of the aluminum board layer; the externalwallboard main body and the edge sealing layers form a wall body; angle steel is arranged at each edge of the wall body; and square steel keels parallel to the cement mortar plastering layer are arranged on the angle steel. The assembled low-energy-consumption external wallboard has the advantages of good heat preservation effect, high dampproof and waterproof performance and high stability.

Description

technical field [0001] The invention belongs to the technical field of assembled components for buildings, and in particular relates to an assembled low-energy-consumption external wall panel. Background technique [0002] With the rapid development of prefabricated buildings in my country, the application of prefabricated buildings is becoming more and more extensive. Especially in order to reduce building energy consumption and shorten the construction period, some of the current prefabricated buildings are assembled with frame structures. In the way of prefabricated exterior wall panels, prefabricated exterior wall panels are prefabricated and integrated in the factory before being shipped to the construction site. However, since most of the current prefabricated exterior wall panels are directly used as the exterior walls of buildings, the requirements for their thermal insulation performance are relatively high, and the thermal insulation effect of prefabricated exterior...

Problems solved by technology

However, since most of the current prefabricated exterior wall panels are directly used as the exterior walls of buildings, the requirements for their thermal insulation performance are relatively high, and the thermal insulation effect of prefabricated exterior wall panels commonly used in the market is not ideal, resulting in increased energy consumption of buildings
