The invention relates to a cable-stayed prestressed reinforcing rib type crane cross beam. The cross beam is provided with a cross beam body (1) and is characterized in that one, two or more groups ofprestressed reinforcing ribs are arranged in the cross beam body (1), wherein each group of prestressed reinforcing ribs consists of three prestressed reinforcing ribs and is positioned on the crosssection of the cross beam body, a first prestressed reinforcing rib (31) and a second prestressed reinforcing rib (32) are obliquely and symmetrically arranged, a third prestressed reinforcing rib (33) is transversely arranged and located between the first prestressed reinforcing rib (31) and the second prestressed reinforcing rib (32), and the two ends of the third prestressed reinforcing rib (33) are fixed to the lower end of the first prestressed reinforcing rib (31) and the lower end of the second prestressed reinforcing rib (32); the upper ends of the first prestressed reinforcing rib (31) and the second prestressed reinforcing rib (32) are respectively fixed to the upper part of the side surface of the cross beam body (1); and the third prestressed reinforcing rib (33) is fixed to the bottom of the cross beam body (1).
本发明涉及一种斜拉预应力加强筋式起重机横梁,具有横梁梁体(1),其特征在于:横梁梁体(1)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3个预应力加强筋组成,位于横梁梁体的横截面上,其中,第一预应力加强筋(31)、第二预应力加强筋(32)斜向对称设置,第三预应力加强筋(33)横向设置,位于第一预应力加强筋(31)、第二预应力加强筋(32)之间,第三预应力加强筋(33)的两端与第一预应力加强筋(31)、第二预应力加强筋(32)下端固定;第一预应力加强筋(31)、第二预应力加强筋(32)上端分别与横梁梁体(1)侧面的上部固定;第三预应力加强筋(33)与横梁梁体(1)底部固定。
