Suspension vault structure for high-temperature flue of coke oven

The utility model discloses a hanging vault structure for a high-temperature flue of a coke oven. The structure consists of a hanging beam fixed on a flue concrete foundation and a flue top plate hung below the hanging beam through a hanging piece, the suspension beam is fixed on a flue concrete foundation and can be in various forms such as I-shaped steel, channel steel and rail steel; the hanging piece can be anchored on the top plate, can lift the top plate through the through hole, and can be connected with the top plate through an expansion bolt; the flue top plate is formed by laying a plurality of refractory brick types; the vault can be a flat top, an arc top, a pinnacle and the like. The structure has higher high-temperature waste gas impact resistance and larger deformation space, and does not generate horizontal thrust on the side wall of the flue. 本实用新型专利公开了一种焦炉高温烟道吊挂拱顶结构，该结构由固定在烟道混凝土基础上的悬吊梁，以及通过悬吊件悬挂于悬吊梁下的烟道顶板构成；悬吊梁固定在烟道混凝土基础上，可以是工字钢、槽钢、轨道钢等多种形式；悬吊件可以锚固于顶板，也可以通过穿孔提拉顶板，也可以通过膨胀螺栓连接顶板；烟道顶板由多种耐火砖型砌筑而
