Structure and construction method of segment prefabricated concrete T-shaped beam
The invention discloses a structure and a construction method of a segment prefabricated concrete T-shaped beam, and relates to the technical field of bridge engineering construction. The structure comprises a plurality of middle T-shaped beam segments, wherein first tooth keys are arranged at the two ends of each middle T-shaped beam segment; two end T-shaped beam segments, which are arranged at the two ends of the multiple middle T-shaped beam segments correspondingly, wherein second tooth keys are arranged at the ends, close to the middle T-shaped beam segments, of the end T-shaped beam segments; external pre-stressed tendons, which are connected with the steering blocks of the plurality of middle T-shaped beam segments in a penetrating manner; and internal pre-stressed tendons are connected with the plurality of middle T-shaped beam segments and the two end T-shaped beam segments in a penetrating manner. According to the structure, temporary tensioning is conducted on the middle T-shaped beam segments through the external pre-stressed tendons, the external pre-stressed tendons penetrate through the steering blocks to achieve permanent tensioning on the middle section, then symmetrical tensioning is conducted on all the T-shaped beam segments through the internal pre-stressed tendons, the construction quality is guaranteed, meanwhile, the construction process is simplified, the construction cost is saved, and later maintenance and repair are facilitated.
本发明公开了一种节段预制混凝土T型梁的结构及施工方法，涉及桥梁工程建设技术领域，包括：多个中间T梁节段，中间T梁节段的两端设置有第一齿键；两个端部T梁节段，分别设置于多个中间T梁节段的两端，端部T梁节段靠近中间T梁节段的一端设置有第二齿键；体外预应力筋，与多个中间T梁节段的转向块贯穿连接；体内预应力筋，与多个中间T梁节段和两个端部T梁节段贯穿连接；该结构先通过体外预应力筋对中间T梁节段进行临时张拉，体外预应力筋贯穿于转向块，实现对中间节段的永久张拉，再通过体内预应力筋对所有T梁节段进行对称张拉，在保证施工质量的同时，简化施工流程，节省施工成本，便于后期养护维修。
