Side span support structure of continuous T-structure viaduct overcrossing existing line
A continuous T-structure viaduct side span support structure overcrossing existing line comprises opposite-pulling type suspenders and a beam bottom bracket, the opposite-pulling type suspenders are arranged in a 4*2 structure layout (four in the transverse direction and two in the longitudinal direction), and the upper portions of the opposite-pulling type suspenders are supported on the top of a foundation structure (namely a bridge body structure with pouring construction work completed). And the lower parts of the opposite-pulling type suspenders are connected to a cross beam of the beam bottom bracket. The support structure provided by the invention can effectively solve the problem that the lower space is limited during side span construction of the continuous T-structure viaduct overcrossing the existing line, and meanwhile, compared with a floor type support method and an attached type support method, the support consumption is reduced, and the cost investment is greatly reduced. A hanging basket needed by a traditional hanging bracket is omitted, and compared with a traditional bracket, the safety of the hanging bracket is guaranteed, and meanwhile the use amount of supports is reduced. The support structure has the advantages of being simple in structure, convenient to disassemble and assemble, short in construction period, safe and reliable, and is particularly suitable for construction of bridges crossing existing lines.
一种上跨既有线路的连续T构高架桥边跨支架结构，包括对拉式吊杆和梁底托架，对拉式吊杆采用4x2(横向四根，纵向两根)根结构布局，对拉式吊杆上部支撑在基础结构的顶部(即已经完成浇筑施工工作的桥梁主体结构)，对拉式吊杆下部连接梁底托架的横梁上。本发明专利提出的支架结构可有效解决上跨既有线路连续T构高架桥在进行边跨施工时下部空间有限的问题，同时较落地式支架法和附着式支架法而言，减少了支架用量，大大降低费用投入。本发明减去了传统吊架需要的挂篮，相对于传统托架而言在保障其安全性的同时也减少了支架用量。本发明支架结构具有结构简单、拆装方便、工期短、安全可靠的优点，尤其适用于上跨既有线路的桥梁施工。
