Abstract
The invention provides a quick assembling and disassembling steel-structure pedestrian overpass which comprises piers, a bridge arranged on the piers and provided with a bridge deck, stairs arranged at two ends of the bridge, and guardrails arranged on two sides of the bridge and the stairs. The quick assembling and disassembling steel-structure pedestrian overpass is characterized in that the bridge is composed of a plurality of I-beams with through holes and connecting components; the connecting components include end plates, clamping plates and connecting plates, the end plates are arranged at the head and tail ends of each I-beam and provided with through holes, the clamping plates are arranged in grooves of the I-beams and provided with through holes, and each connecting plate provided with through holes is arranged between every two adjacent clamping plates, and bolts and nuts are arranged in the through holes. The pedestrian overpass can be assembled or disassembled quickly and conveniently, so that time for building or demolishing is shortened greatly, and road traffic pressure is relieved; furthermore, the disassembled pedestrian overpass is reusable, thus materials and cost are saved greatly. In addition, due to an assembled structure, assembly parts can be produced and transported in batches, and the pedestrian overpass is beneficial to large-scale and intensive production, transportation and assembly.
Description
Technical field
The present invention relates to the steel structure footbridge of a kind of pedestrian overcrossing, particularly a kind of quickly dismantled, belong to bridge construction design and manufacturing technology field.
Background technology
Pedestrian overcrossing is indispensable architectural construction in urban construction, and it can solve people, car mixes the current traffic safety problem existing.But because existing pedestrian overcrossing mostly is steel and concrete structure, while building in the city many people, vehicle flowrate is large, understand because the time is long, take limited path resource, and bring adverse effect to urban highway traffic and people's trip.Meanwhile, this permanent bridge changes need to remove time in urban planning, not only time-consuming taking a lot of work, once and remove and again cannot utilize, cause waste of raw materials.Though also develop the pedestrian overcrossing of steel work at present, but still have Heavy Weight, welding procedure amount is large, dismounting inconvenience, volume is large, transports the problems such as difficulty.Therefore be necessary prior art to be improved.
Summary of the invention
For solving existing pedestrian overcrossing because adopting steel and concrete structure, and take path resource when building or remove, time-consuming taking a lot of work, can not reuse, or because adopting steel work to have Heavy Weight, the problems such as welding procedure amount is large, dismounting inconvenience, the invention provides a kind of steel structure footbridge of quickly dismantled.
The present invention 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 consists 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, by bolt and nut, fix bridge, ladder on several bridge piers 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 present invention 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 the pedestrian overcrossing after removing is reusable; material and cost have greatly been 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.
