Precast side fascia with decorative concrete surface layer and manufacturing method thereof

Abstract

The invention discloses a precast side fascia with a decorative concrete surface layer. The precast side fascia comprises an inner cement fiberboard, a sandwich insulating layer and a ribbed outer concrete plate and is characterized in that the ribbed outer concrete plate comprises reinforcing ribs and a surface plate; an outer surface of the surface plate is a colorized concrete surface layer with textures; and the sandwich insulating layer is filled between the reinforcing ribs. The precast side fascia provided by the invention adopts the colorized concrete molded exterior facing and has a low price, multiple types of surface textures, thin thickness of outer concrete, light self-weight, no risk of exterior facing spalling and good resistance.

Description

technical field [0001] The invention relates to a building exterior wall panel, in particular to a prefabricated sandwich reinforced concrete exterior wall panel. Background technique [0002] There are many types of prefabricated exterior wall panels in the prior art, and there are many ways to connect and fix the exterior wall panels and structures. At present, the most widely used prefabricated concrete exterior wall panels are usually made by the reverse method, and the exterior surface is made of facing bricks. This kind of wall It is difficult to make the board, especially the placement of the insulation layer is difficult, and the weight is also relatively large. "Cold bridge" is difficult to avoid, and the cost is also high. There is no report on a heat-insulating composite exterior wall panel in which an artistic concrete surface layer is used as an outer layer and a cement fiber board is used as an inner layer. Contents of the invention [0003] The technical pr...
