The specific embodiment
As shown in Figure 1, large span ready-package pedestrian overcrossing of the present utility model comprises pontic 2 and is fixed on railing body 3 on the pontic, pulley 1a, 1b and 1c are installed in pontic 2 bottoms, and the effect of pulley is by finishing setting up of pedestrian overcrossing at obstacle limit 4b fast toward the opposite bank 4a promotion overline bridge of zanjon 4.
Pontic 2 is made of a plurality of pontic segmentations, pontic segmentation of expression between two dotted lines among Fig. 1, each pontic segmentation has two couple who longitudinally extends in parallel and goes up truss 5 and following truss 6 (a pair of truss 5 and the following truss 6 gone up of pontic one side has been shown among Fig. 1), every pair of a plurality of oblique connecting rod 7 that incline direction replaces variation that passes through of going up truss 5 and following truss 6 links to each other, and pulley 1a, 1b and 1c are placed in down truss 6 bottoms.
Fig. 2 shows between the two adjacent pontic segmentations and realizes the structure partial vertical view of connection fast by flange, as shown in the figure, the promptly right section of the pontic segmentation on the right goes up the flange portion that truss 6a has the 61a of pipe portion and is positioned at two ends, the pipe portion 61a left and right sides, only shows flange portion 62a of its left end among the figure; The flange portion that truss 6b also has the 61b of pipe portion and is positioned at two ends, the pipe portion 61b left and right sides is gone up in the pontic segmentation on the same left side i.e. left side section, only shows a flange portion 62b of its right-hand member among the figure.As shown in Figure 3, the right flange portion 62b of last truss 6b and the left flange portion 62a of last truss 6a interconnect by connecting bolt 63, similarly, the adjacent of the adjacent pontic segmentation in the left and right sides interconnects by same flange connection between the truss 5 down, thus two adjacent pontic segmentations is fixed together.
As shown in Figure 4, intubate 8 is established in the side of last truss 5, is appreciated that intubate 8 also can be arranged on down the side of truss 6, as shown in Figure 5, and intubate 8 bottoms baffled 9.Railing body 3 comprises the segmentation of more piece railing body, the segmentation of every joint railing body comprises two cross bars and the montant that is positioned at the cross bar two ends and links to each other with cross bar that can be used as hand rail, lower end by montant is inserted in the intubate 8 segmentation of more piece railing body is separately fixed at the side of the more piece pontic segmentation that is linked to be pontic, so that guarantee the personnel's that walk safety on pontic.
The utility model large span ready-package pedestrian overcrossing is a trussed construction, before setting up, at first the flange portion with the truss up and down 5,6 of adjacent pontic segmentation interfixes, form whole pontic, the montant lower end of each railing body segmentation is being inserted in the intubate 8 of pontic both sides, thereby establish the safety of railing in the pontic both sides with the personnel that guarantee to walk on it. as shown in Figure 1, the length of the pontic 2 that is linked to be by a plurality of pontic segmentations should be greater than the twice of the width of obstacle (being zanjon 4)
Establish pulley in pontic 2 bottoms, finish setting up of pedestrian overcrossing fast by promoting overline bridge toward opposite bank 4a at obstacle limit 4b.Half section power of toppling that deadweight causes before overline bridge promotes to overcome overline bridge in the erection process should be guaranteed in the position of pulley, finishes overline bridge smoothly and sets up, and realizes the purpose of leaping over obstacles.
After overline bridge is finished using, at first pull down the segmentation of a plurality of railing body, unclamp the connection of the flange portion between the adjacent pontic segmentation then, storage and carrying are convenient in a plurality of railing body segmentation under the dismounting and a plurality of pontic segmentation.
