Abstract

The invention provides an external wall panel used for civil construction. The external wall panel comprises a first layer, a second layer, a third layer, a fourth layer, a fifth layer, a sixth layer and a seventh layer sequentially from outside to inside, wherein the first layer comprises, by weight, 60-70% of cement and 30-40% of glass fibers; the second layer comprises, by weight, 20-30% of gravel, 30-40% of straw, 20-30% of fibers and 10-30% of phenolic foam; the third layer is of a double-layer structure and comprises an aerogel felt layer attached to the second layer and a thermal insulation grain layer attached to the aerogel felt layer; the fourth layer is attached o the third layer and composed of a steel wire gauze; the fifth layer is of a three-layer structure and comprises a phenolic foam body as the intermediate layer, and two PVC thin film layers are arranged on and under the phenolic foam body correspondingly; the sixth layer is attached to the fifth layer and composed of a steel wire gauze; and the seventh layer is a fiber cloth layer. By adoption of the external wall panel used for civil construction, the structural stability and strength of a wall body are improved, the mechanical property of the wall panel is further improved by arranging the steel wire gauzes, and the thermal insulation performance is greatly improved by arranging the PVC thin film layers.

Description

technical field [0001] The invention relates to the field of civil construction engineering, in particular to an exterior wall panel for civil construction. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction, that is, the construction on the ground or underground, on land or in water, directly or indirectly for human life. Various engineering facilities for production, military and scientific research services, such as houses, roads, railways, transportation pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, and protection engineering. [0003] The wall panel is a house structure composed of walls and floors as a load-...
