Abstract
The utility model provides a frame-free type steel heat preservation wall capable of achieving fire protection for 2 hours. The frame-free type steel heat preservation wall comprises an outer wall, a heat preservation layer and an inner wall board, wherein the outer wall, the heat preservation layer and the inner wall board are sequentially distributed from outside to inside; the outer wall is formed by splicing several galvanized steel sheets in a left-and-right mode, each galvanized steel sheet is composed of a slab, a left bent portion and a right bent portion, and the left bent portions and the right bent portions of two adjacent galvanized steel sheets are clamped; the inner wall board is fixedly connected with the left bent portions and the right bent portions; a cavity defined by the inner wall board, the left bent portions and the right bent portions is filled with the heat preservation layer. An edge folding rib in the middle of the wall can form a bearing steel rib, so another supporting structure does not need to be arranged for the wall, and the wall bears self weight and the weight of an upper structure by depending on itself; the heat preservation layer enables the wall to keep certain strength under the high temperature condition. The characteristics that a traditional steel structure is convenient and fast to install and capable of being recycled and components are light in self weight are maintained, and the fire resistance of the steel structure wall is promoted to a level when a fire burns for 2 hours.
