Lap joint type continuous overhead beam
The invention relates to a lap joint type continuous overhead beam, and belongs to the field of existing line construction. Comprising main beams and short beams. The upper part of one end of the main beam is inwards retracted, and the lower part of the other end of the main beam is inwards retracted to form staggered floors; the upper portions of the two ends of each short beam are both retracted inwards to form staggered layers, and the staggered layers at the two ends are in axial symmetry. The heights of the main beam and the short beam are the same, and the heights of the retracted parts of the main beam and the short beam are half of the overall height; a plurality of main beams are matched and connected end to end in a staggered manner to form a beam body, and the short beams complement the lower indented ends of the whole beam body; and the lengths of the indented parts of the main beam and the short beam are the same. The Z-shaped connection mode is adopted for fixed connection, connection is firm, and when an underpass railway bridge and culvert and other facilities are additionally built under the condition that running is not interrupted, a running railway can be effectively reinforced and protected.
本发明涉及一种搭接式连续架空梁，属于既有线施工领域。包括主梁和短梁；主梁的一端上部向里缩进，另一端下部向里缩进，形成错层，两端的错层相互对称；短梁的两端上部均向里缩进，形成错层，两端的错层呈轴对称；主梁和短梁的高度相同，主梁和短梁的缩进处的高度均为整体高度的一半；若干主梁首尾错层配合相接形成梁体，短梁将整个梁体的下部缩进端部补全；主梁和短梁缩进处的长度均相同。采用z型连接方式固定连接，连接牢固，在不中断行车的条件下增建下穿式铁路桥涵及其它设施时，能对行车铁路有效加固和防护。
