Description
Technical field
The present invention relates to mechanical structure and traffic engineering technical field, more particularly to a kind of make-shift bridge device.
Background technology
Make-shift bridge is the Simple bridge of temporary erection.The bridge constructed and set up for convenience, can for construction machinery
It is smoothly convenient current, major trunk roads driving is changed its course, it is necessary to relieve traffic congestion sometimes for heavy construction such as subway station etc. is built.Especially
It is in city may no sufficient space build interim sidewalk, dredge friendship using make-shift bridge structure is built on river course
Logical, general construction requirement is tight.Major urban arterial highway track is more, and vehicle flow is big.How to accomplish economy, safety and easy construction, be
One major issue of required consideration when designing make-shift bridge.
Traditional temporary construction steel suspension bridge is also wide with regard to 4~8m, does not use beams of concrete substantially come as make-shift bridge.In addition
Traditional steel suspension bridge is longitudinally arranged using Bailey beam, i.e., Bailey beam is identical with road arrangement direction.In Urban Metro Construction, especially
Subway station is built under major trunk roads, the wide left and right of the general 30m of engineering make-shift bridge is discongested.Urban Bridge volume of traffic is big, right simultaneously
Noise pollution requirement is strict, especially through school, hospital, resident living area.Traditional steel suspension bridge arrangement form, which is difficult to meet, to be wanted
Ask, influence the actual cross-section of river in river course, next to that noise is inevitable.According to permanent concrete bridge structure, it is invested
Cost is high, speed of application is slow, removal cost is higher.And can not possibly reuse.
Bailey beam combines frame structure by Bailey bracket and horizontal-associate frame by Bei Leixiao, and Bailey bracket and shellfish thunder pin are standards
Commodity fittings, can with it splice be assembled into many components, equipment.As shown in figure 1, being Bailey bracket structure, such as Fig. 2 and Fig. 3
For shellfish thunder latch structure.
Bailey bridge is also referred to as " assembly type steel bridge on highway ", and original name is " 321 " highway steel bridge.It is the combat readiness highway steel of China
Bridge.Bailey bridge is to be widely used in the world, a kind of the most popular bridge, and it has simple in construction, convenient transportation, sets up fast
