The pedestrian overpass is also called a pedestrian overpass. The method is generally built in the areas with large traffic flow and dense pedestrians, or on intersections, squares and railways. The pedestrian overpass only allows pedestrians to pass through, is used for avoiding conflict when traffic flow and pedestrian flow planes are intersected, ensures safe crossing of people, improves the speed of the vehicle, and reduces traffic accidents. The traditional concrete type pedestrian bridge has the defects of long construction period, occupation of road surface, influence on traffic, difficulty in dismantling and the like, and is gradually abandoned for the construction of the cities which are different day by day. The replaced aluminum alloy pedestrian bridge has many advantages, most parts are pre-assembled in factories, and large components can be erected and assembled to finish use by directly transporting to a designated place, so that the operation is fast and convenient; the surface of the aluminum alloy is compact, corrosion resistant and long in service life, and can be used in coastal cities or areas with serious air pollution without worry; the surface is bright and clean and has good decoration effect; the aluminum alloy structure is basically maintenance-free during use, so that the maintenance cost can be saved, and the total construction and operation cost is lower than that of a steel structure overpass; the aluminum metal removed after being not used is high in recovery value and can be directly recovered and reused, and the environment-friendly concept of current green environment protection and zero waste is met. Due to the advantages of the aluminum alloy overpass, the aluminum alloy overpass is gradually the mainstream of the urban pedestrian overpass at present.
The mode combination that adopts the section bar bolt to connect mostly between each part of current aluminum alloy pedestrian overpass ladder way, because the aluminium alloy makes up the department of meeting not integrated into one piece, often unavoidable can appear the ponding on ladder way surface and can leak from the gap infiltration, from the bridge bottom drippage, influence pedestrian under the bridge past. In addition, the ramp of the existing aluminum alloy pedestrian overpass ladder way is formed by riveting an aluminum plate, the strength of the aluminum plate is insufficient, the aluminum plate is often damaged by tilting due to the failure of a screw or a rivet caused by impact and abrasion, and potential danger is caused to pedestrians pushing bicycles, pedestrians pulling a suitcase and pedestrians pushing carts.
The following inquired prior relevant documents about the aluminum alloy pedestrian overpass:
1. an aluminum alloy pedestrian bridge; application No.: CN 201921695575.4; the applicant: medium aluminum south aluminum (fujian) aluminum structure technology development ltd; and (3) abstract: an aluminum alloy pedestrian bridge comprises an aluminum alloy truss, a supporting platform and a plurality of stairs; the truss comprises a grab rail, a lower chord connecting rod and a plurality of truss components, the truss components are connected through the grab rail and the lower chord connecting rod, and an anti-skid floor is arranged on the upper surface of each truss component; the stairs are connected with the truss through a supporting platform, and pier columns are arranged below the supporting platform and the stairs; the stair comprises a stiffening crossbeam, a stair side beam, a side rod upright post, a side rod upper handrail and a side rod lower handrail, wherein the two ends of the stiffening crossbeam are connected with the stair side beam; the aluminum alloy material has strong corrosion resistance, light self weight and longer service life; the stair structure is firm.
2. A connecting device for a main bridge and a ladder way of an aluminum alloy overpass; application No.: CN 201821977599.4; the applicant: guiyang Almagma design research institute, Inc.; Abstract: the utility model provides an aluminum alloy overline bridge main bridge and ladder way connecting device, includes that the main bridge girder erects the web member, and the web member is erect to the truss, crossbeam and ladder way longeron, and the crossbeam erects the web member through the main truss with the main bridge and is connected, and ladder way longeron passes through the support with the crossbeam and supports the crossbearer and be connected. The utility model discloses having reduced steel construction platform area greatly, having reduced the whole cost of overline bridge, made the pontic lighter and more slim and graceful, reinforcing overline bridge aesthetic property improves the anti-seismic performance of overline bridge.
As can be seen, the sealing performance of the existing aluminum alloy overpass ladder way is insufficient, and no literature record related to the ramp of the aluminum alloy pedestrian overpass ladder way is found.
