Bridge rectangular high-pier single-pier bent cap triangular bracket system and construction method thereof
The invention discloses a bridge rectangular high-pier single-pier bent cap triangular bracket system and a construction method thereof. Before a pier body of a rectangular high pier or a single pierof a bridge is capped, bracket boxes are symmetrically pre-embedded in the pier body with the center of the high pier or the single pier as the symmetry axis, at least one set of opposite-pull holes are reserved in the bracket boxes and the pier body of the high pier or the single pier, and after the pier body is capped, brackets of the set size are inserted into the pre-embedded bracket boxes ofthe pier body and are oppositely pulled and fixed by deformed steel bars; a triangular bracket is fixed to each bracket, a sand box is placed on each triangular bracket, an I-shaped steel cross beam is arranged on the sand box, a double-spliced bailey beam is arranged on the I-shaped steel cross beam, an I-shaped steel distribution beam is arranged on the double-spliced bailey beam, a triangular supporting frame used for adjusting a capping beam bottom die is placed on the I-shaped steel distribution beam, and a capping beam formwork is laid on the triangular supporting frame; and then a steelbar of the bent cap is bound, and finally the bent cap is poured. According to the construction method, high-altitude welding construction is avoided, safety and reliability of a support system are guaranteed, and unreliable factors of people in high-altitude welding are technically avoided.
一种桥梁矩形高墩独墩盖梁三角托架体系及施工方法。在桥梁矩形高墩或独墩的墩身封顶前，在墩身上以高墩或独墩中心为对称轴对称预埋牛腿盒，并在牛腿盒和高墩或独墩的墩身上预留至少一组对拉孔，墩身封顶后，将设定尺寸的牛腿插入墩身预埋牛腿盒中，通过螺纹钢对拉固定，在牛腿上固定三角托架，在三角托架上放置砂箱，砂箱上设置工字钢横梁，工字钢横梁上设置双拼贝雷梁，双拼贝雷梁上设置工字钢分配梁，工字钢分配梁上放置用于调整盖梁底模的三角支撑架，在三角支撑架上铺设盖梁模板，然后绑扎盖梁钢筋，最后浇筑盖梁，本发明无高空焊接施工，保证了支架体系的安全可靠，从技术上规避了高空焊接中的人的不可靠因素。
