The utility model discloses an articulated extension segment structure of screed of variable camber, characterized by: fuse left hinged frame and right hinged frame through shaft hole hinge structure,at left hinged frame and welding of right hinged frame middle part or the dull device that encircles of bolted connection, dull both ends of encircleing the device have a bearing respectively, through levogyration and dextrorotation bearing, adjust left hinged frame and right hinged frame and form a constant angle degree. At the screed during operation, the change hunch that can satisfy basic road surface also can satisfy paving of both ends curb, and twice change hunch once paves, has saved time and personnel's cost like this for the user, has obtained user's approval. 本实用新型公开了种可变拱度的熨平板铰接加长段结构，其特征是：将左铰接框架和右铰接框架通过轴孔铰接结构连成体；在左铰接框架和右铰接框架中部焊接或螺栓连接单调拱装置，单调拱装置的两端分别具有轴承，通过左旋和右旋轴承，调节左铰接框架和右铰接框架形成定角度。在熨平板工作时，即可满足基础路面的变拱也可满足两端路肩的摊铺，两次变拱次摊铺，这样为用户节省了时间和人员的花费，已获得用户的认可。
