Fixing structure of stand column of main tower support of cable-stayed bridge without backstays
The invention discloses a fixing structure of a back-cable-free cable-stayed bridge main tower support stand column in the technical field of back-cable-free cable-stayed bridge main tower construction. The fixing structure aims at solving the problem that in the prior art, a concrete beam is prone to cracking due to a support stand column. The method comprises the steps that an upper force equalizing plate and a lower force equalizing plate which are in force transmission connection through an anchoring part increase the friction area, friction force generated for resisting horizontal tension in unit area is reduced, a cover plate of a concrete beam is prevented from being cracked and damaged by the horizontal tension, and an inhaul cable transmits the horizontal tension between the upper force equalizing plate and the lower force equalizing plate and resists the friction force generated by the horizontal tension. The support stand column transmits horizontal pulling force to the upper force uniformizing plate through the upper force transmission fixing piece and meanwhile plays a role in fixing the inhaul cable, and the adjustable abutting piece abuts against the vertical supporting piece into the cover plate and the bottom plate to prevent the cover plate from being damaged due to the fact that the deflection of the cover plate is too large under the vertical pressure of the support stand column.
本发明公开了一种无背索斜拉桥主塔施工技术领域的无背索斜拉桥主塔支架立柱的固定结构，旨在解决现有技术中支架立柱易使混凝土梁开裂的问题。其包括：由锚固件传力连接的上均力板与下均力板增加摩擦面积，单位面积上为抵抗水平拉力产生的摩擦力变小，防止混凝土梁的盖板被水平拉力拉裂损坏，拉索在上均力板与下均力板之间传递水平拉力和抵抗水平拉力产生的摩擦力，支架立柱通过上传力固定件向上均力板传递水平拉力，同时起到固定拉索的所用，可调顶紧件将竖向支撑件顶紧于盖板与底板内防止在支架立柱的竖向压力下盖板挠度过大损坏。
