Abstract: Hollow internal formwork metal mesh cement internal partition wall is referred to as good fixed wall. It is a kind of non demolition internal formwork wall which uses metal mesh as the internal structure of the wall and covers its surface with cement mortar. The hollow inner membrane metal mesh is made of cold-rolled steel and rolled to form the framework of the hollow internal mold. Good fixed wall not only inherits the advantages of traditional brick wall, but also improves it, making up for the characteristics of poor sound insulation, long construction period and easy to produce cracks, so that the construction technology quality of partition wall has been developed. Therefore, this paper discusses its construction technology, hoping to provide some reference for the development of hollow internal formwork metal mesh cement internal partition wall construction technology.
