The invention relates to a cable-stayed prestressed reinforcing rib type crane cross beam. A cross beam body is internally provided with one, two or more groups of prestressed reinforcing ribs, wherein each group of prestressed reinforcing ribs consists of six prestressed reinforcing ribs and is positioned on the cross section of the cross beam body, a first prestressed reinforcing rib and a second prestressed reinforcing rib are obliquely and symmetrically arranged, a third prestressed reinforcing rib and a fourth prestressed reinforcing rib are obliquely and symmetrically arranged, the lowerends of the first prestressed reinforcing rib and the second prestressed reinforcing rib are fixedly connected, the lower end of the third prestressed reinforcing rib is connected with the lower endof the first prestressed reinforcing rib through a fifth reinforcing rib which is transversely arranged, the lower end of the fourth prestressed reinforcing rib is connected with the lower end of thesecond prestressed reinforcing rib through a sixth reinforcing rib which is transversely arranged, the upper ends of the first to fourth prestressed reinforcing ribs are respectively fixed to the upper part of the side surface of the cross beam body, and the fifth prestressed reinforcing rib and the sixth prestressed reinforcing rib are fixed to the bottom of the cross beam body.
本发明涉及一种斜拉预应力加强筋式起重机横梁,横梁梁体内设有1组、2组或多组预应力加强筋,每组预应力加强筋由6个预应力加强筋组成,位于横梁梁体的横截面上,第一预应力加强筋、第二预应力加强筋斜向对称设置,第三预应力加强筋、第四预应力加强筋斜向对称设置,第一预应力加强筋和第二预应力加强筋的下端连接固定,第三预应力加强筋下端与第一预应力加强筋下端之间通过横向设置的第五加强筋连接,第四预应力加强筋下端与第二预应力加强筋下端之间通过横向设置的第六加强筋连接;第一预应力加强筋至第四预应力加强筋的上端分别与横梁梁体侧面的上部固定;第五预应力加强筋、第六预应力加强筋与横梁梁体底部固定。
