The utility model completes by following technical proposal: a kind of steel structure footbridge of quickly dismantled, comprise bridge pier, and be located at the bridge with bridge floor on bridge pier, with the ladder of being located at bridge two ends, be located at the guardrail of bridge and ladder both sides, it is characterized in that bridge is made up of several i iron and the coupling assembling of establishing through hole on it, many i iron are connected into bridge by coupling assembling.
Described coupling assembling comprises the end plate of establishing through hole on its that be located at i iron head and the tail two ends, and be located at the clamp of establishing through hole on its in i iron groove, and be located at the connecting plate of establishing through hole on its between clamp between two, in through hole, be provided with bolt and nut, to longitudinally connect i iron between two by end plate, thereby extend bridge length, more laterally connect i iron between two by clamp and connecting plate, increase bridge width, and fix by bolt and nut.
Described bridge floor comprises is located at the several piece panel of establishing through hole on its on bridge successively, is provided with bolt and nut in through hole, and this through hole is corresponding with the through hole on i iron, to connect panel on bridge by bolt and nut.
Described ladder comprises two cant beams arranged side by side, and be located at successively several grades of L-squares on two cant beams, wherein, each cant beam by i iron with and on establish through hole connection end plate form, in through hole, be provided with bolt and nut, to longitudinally connect i iron between two by connecting end plate, and be fixed by bolt and nut, thereby extend cant beam length.
The horizontal end face of described each L-square and the vertically two ends of end face are welded on respectively on two cant beams, to form multistage ladder.
Described bridge pier is made as several circles or ellipse or the rectangle column of different length, the top of each root post and bottom are respectively equipped with top board and the chassis with through hole, in through hole, be provided with bolt and nut, to pass through bolt and nut fixed underpan in underground reinforced concrete foundation, fix bridge, ladder on several bridge piers by bolt and nut again, thereby form the pedestrian overcrossing with ladder, bridge.
Described guardrail comprises vertical rod, is fixed on the cross bar between vertical rod, and the bottom of each vertical rod is provided with the base plate with through hole on it, is provided with bolt and nut in through hole, to connect guardrail in bridge and ladder both sides by bolt and nut.
The utlity model has following advantages and effect: adopt such scheme; can assemble quickly and easily or remove pedestrian overcrossing; greatly shortened the time of building or dismounting, alleviated road traffic pressure, and pedestrian overcrossing after removing is reusable; material and cost are greatly saved; in addition, owing to having adopted modular construction, can be mass, transport assembly; being conducive to scale, intensive production, transportation and installation, is a desirable pedestrian overcrossing in fact.
