Description
Technical Field
The invention relates to the technical field of highway and railway dual-purpose bridges, in particular to a hanging template system for a post-pouring section of a middle flange of a highway beam of a highway and railway dual-purpose bridge.
Background
The highway-railway dual-purpose bridge has the characteristic of multiple purposes, one bridge can meet the traffic requirements of two ways of highways and railways, and the bridge type is more and more applied to modern bridge design along with the rapid development of high-speed railways.
When the highway and railway dual-purpose bridge is designed, a common railway is arranged at the lower layer, and a highway is arranged at the upper layer. Because the requirement for railway running is high, in order to avoid the influence of objects falling above the upper layer on the railway running safety, the middle of the left and right width of the upper layer highway beam is usually designed to be a closed structure, namely, the flange plates in the middle of the left and right width highway beams are widened, and the clear distance is only about 2 cm. When the main body of the highway beam is constructed, the middle widening section is usually not constructed temporarily, and pouring construction is carried out after the main body is constructed. When the post-cast section between the left and right road beams is constructed, a full framing support is erected to form a template supporting system, or a hanging rod hole is arranged on the post-cast section, and the hanging template is used for construction. The method has the advantages of large workload of installing and detaching the bracket, high safety risk, long time consumption, more required materials and higher cost.
