Temporary buttress of reinforced concrete superposed beam overcrossing existing bridge
A plurality of longitudinal columns of upper stand columns of the buttress penetrate through intervals between framing of a built bridge, a plurality of horizontal distribution beams are arranged at the upper ends of the upper stand columns, double-spliced I-shaped steel is arranged on the upper end faces of the distribution beams, and the upper portions of the double-spliced I-shaped steel are used for supporting the newly-built bridge. According to the invention, by utilizing the interval between the framing of the built bridge, the stand column of the temporary buttress passes through the interval, and the distribution beam and the double-spliced I-shaped steel arranged at the upper end of the stand column support the newly-built bridge. The gate-type temporary buttress can be suitable for the limited space of a road and building dense area, the structure and construction method of a traditional gate-type temporary buttress are changed, and the gate-type temporary buttress has the advantages that the construction cost is reduced, and the construction period is shortened.
一种上跨现有桥梁的钢混叠合梁临时支墩，支墩的若干纵列上立柱穿过已建桥梁分幅之间的间隔，上立柱上端设置若干水平的分配梁，分配梁上端面设置双拼工字钢，双拼工字钢上方用于支撑新建桥梁。本发明利用已建桥梁分幅之间的间隔，临时支墩的立柱从间隔中穿过，立柱上端设置的分配梁和双拼工字钢将新建桥梁支撑。本发明可适用于道路和建筑密集区域有限空间，改变了传统门式临时支墩的结构和施工方法，具有降低建设成本，减少建设周期的优势。
