The utility model is achieved by the following technical solution:A kind of fixation of Change of Hanger Rods of Tied Arch Bridge, adjust Leveling device, it is characterized in that:Including anchor ear and leveling steel case, the anchor ear is by semicircular anchor ear A and semicircular anchor ear B phases To the circular anchor ear being formed by connecting, the both sides of the edge of the anchor ear A and anchor ear B are welded with the connecting plate with bolt hole, institute Stating anchor ear A and anchor ear B and being bolted includes superposed horizontally disposed peace for circular anchor ear, the leveling steel case Loading board I, vertical interval are fixedly installed on multiple installing plates II of the bottom of installing plate I, are fixedly connected on installing plate I, installation Polylith installing plate III between plate II, the top of the installing plate II is plane, and the bottom of the installing plate II is can be with tie-rod The arcuate structure that the arch rib outer surface of arch bridge matches, the height of the installing plate II are sequentially reduced, the bottom of installing plate II Arcuate structure arc top line it is consistent with the angle of inclination of the arch rib of bowstring arch bridge, the arcuate structure of the bottom of installing plate II It is fastened on the top of one of semicircle anchor ear of the anchor ear and welds together with it.
The utility model is in use, anchor ear is mounted by means of bolts on the arch rib of bowstring arch bridge, leveling steel case position In the top of arch rib, now the installing plate I of leveling steel case is horizontal, and can be carried out on the top of installing plate I of leveling steel case Transverse beams Shang interim pocket crane system are installed.
Further, it is the bonding strength that ensures leveling steel case and anchor ear, the bottom of the installing plate III is and tied arch The consistent inclined-plane in the angle of inclination of the arch rib of bridge.
Further, to ensure the bonding strength of anchor ear, the connecting plate bottom is fixedly connected with some pieces of ribs.
The utility model is simple in construction, and constructing operation is convenient, using the form of anchor ear combination leveling steel case, not by arch rib hole Footpath influences, and after initial survey positioning, can directly process in place, directly be fixed using bolt during use, have positioning Simply, accurately, it is easy to adjust, it is convenient to assemble and disassemble the characteristics of, and do not destroy existing structure.The utility model encircles particularly with extra heavy pipe footpath Rib, have and firmly install, precision is high, the advantages of being greatly improved security.The utility model can factorial praluction, it is possible to increase Efficiency of construction.
