Description

Assembling tank-shaped composite beam bridge
Technical field
This disclosure relates to beam bridge field more particularly to a kind of assembling tank-shaped composite beam bridge.
Background technique
In decades since reform and opening-up, with the acceleration of China's modern city process, Bridges in Our Country builds skill Art is quickly grown, and bridge industry is of certain scale.In China's Short/Medium Span Bridge, concrete beam bridge is in the great majority.Concrete Material is considered as the preferred structure material that durability is good, cheap, and concrete beam bridge experienced the hair of decades in China Exhibition, using most.However, the factors such as variation and environmental attack due to structure by use condition are influenced, in addition design and That constructs is improper, all structure can be made by different degrees of damage, cause bridge defect, make Deterioration of Structural Performance, use function It gradually reduces or even completely loses, this feature shows especially prominent in Short/Medium Span Bridge.With the hair of national economy Exhibition and industrialized propulsion, for large number of Mid and minor spans beam bridge, precast assembly technology obtains in bridge course of industrialization To more applications, it is the production and assembled process of standard element by the design and construction process simplification of original inefficiency, is guaranteeing Under the premise of bridge product quality, the bridge construction time greatly shortened, the above is the general of the quick building technology of bridge It reads.Different from traditional beams of concrete precast assembly technology, the quick building technology of tank-shaped composite beam bridge has preferably industrialization Basis and industrialization potential, and requirement more environmentally-friendly, that construction is more quick, preferably meet " light-duty greatly across ".Currently, combination It is H-shaped combination beam that beam, which uses more, and the I-shaped composite beam bridge of double main beam structures is current most widely used structure One of form.The shortcomings that this form is: once Practical Project jackshaft width becomes larger, combined steel plate beam will be by increasing girder number Structure is become more main beam structures by amount.So, cost can be higher by much than the Cost Index of double girders under normal circumstances, It is affected to structure economics.In general, when bridge is wider than 25m, deck-molding is lower, live cannot use big loop wheel machine and limit Made Lifting Capacity, width it is larger when just will use more main beam structures.And when bridge width is moderate, using double girder knots Structure girder the piece number is few, in order to meet structure stress requirement, needs to increase the size of girder and improves material rate, also result in into This substantial increase.And double girder forms structure type when bridge width is larger seems uncoordinated, and aesthetics is caused to reduce.
