Lightweight external hanging prefabricated wallboard and production method thereof

Abstract

The invention provides a lightweight external hanging prefabricated wallboard and a production method thereof. The lightweight external hanging prefabricated wallboard includes a core skeleton, an inner wallboard and an outer wallboard, the core skeleton comprises two outer skeleton layers and an inner skeleton layer arranged between the two outer skeleton layers, each outer skeleton layer comprises a plurality of horizontal lightweight skeletons arranged at intervals, and the inner skeleton layer comprises a plurality of vertical lightweight skeleton arranged at intervals; and the inner skeleton layer is internally provided with a sound insulation felt in a zigzag mode, a void inside the core skeleton is filled with polyurethane foam, the outer surfaces of the outer framework layers are fixed with a steel wire mesh, and the outer surface of the steel wire mesh is provided the inner wallboard or the outer wallboard integrally. The lightweight external hanging prefabricated wallboard has the advantages of light weight, excellent thermal insulation performance, good sound insulation effect and so on, and meanwhile rapid production can be carried out.

Description

technical field [0001] The invention relates to an external hanging wallboard. Background technique [0002] External prefabricated wall panels are an important component of prefabricated buildings. Common prefabricated external wall panels are composed of outer panels and inner panels, that is, filling materials filled between the inner and outer panels. The external prefabricated wall panels in the prior art are usually Pre-buried holes in the prefabricated wall panels, and then fixed on the building structure frame through the external parts, at the openings, the thermal insulation performance of the openings is often reduced, affecting the thermal insulation performance of the entire building. For example, the published patent document CN204386019U discloses a prefabricated exterior wall panel, which is fixed by using a fixing member 140 to pass through the prefabricated wall panel, so that the thermal insulation performance of the insulation board at the perforation is ...

Problems solved by technology

[0002] External prefabricated wall panels are an important component of prefabricated buildings. Common prefabricated external wall panels are composed of outer panels and inner panels, that is, filling materials filled between the inner and outer panels. The external prefabricated wall panels in the prior art are usually Pre-buried holes on prefabricated wall panels, and then fixed them on the building structure frame through external parts. At the openings, the thermal insulation performance of the openings is often reduced, which affects the thermal insulation performance of the entire building.

For example, the published patent document CN204386019U discloses a prefabricated exterior wall panel, which is fixed by using a fixing member 140 to pass through the prefabricated wall panel, so that the thermal insulation performance of the insulation board at the perforation is greatly reduced

In addition, the prefabricated exterior wall panels in the prior art have considered too much thermal insulation performance, but rarely have sound insulation performance
