Embodiment 1

[0049] Such as figure 1 or figure 2 Shown: a pedestrian bridge, including a bridge body, a bridge deck 7 and a guardrail 8 set on the bridge deck 7. The bridge body includes a column 10, a beam 9 and a staircase 11, and the column 10, beam 9, staircase 11 and guardrail 8 are adopted In the traditional steel structure, the bridge deck 7 is joined by a plurality of rectangular composite plates by welding, and the composite plates are fixed on the cross beam 9 by screw connection.

[0050] Such as image 3 Shown: Specifically, the composite board 5 includes an upper panel 1, a lower panel 2, a plurality of round tubes 3 in the middle, and a brazing layer 4 between the round tube 3 and the upper panel 1 and the lower panel 2. The upper and lower ends of the round tube 3 are flanged so that the outer diameter after flanging is larger than the diameter of the round tube; the flanging of the round tube 3 is brazed and connected to the upper panel 1 and the lower panel 2, that is, adjace...

Embodiment 2

[0060] Such as Figure 5 Shown: a pedestrian bridge, including a bridge body, a bridge deck 7, and a guardrail 8 set on the bridge deck 7. The bridge body includes a column 10, a beam 9 and a staircase 11, the column 10 is stacked by multiple composite plates by welding The crossbeam 9 is composed of arc-shaped composite plates spliced ​​by welding; the bridge deck 7 is spliced ​​by multiple composite plates installed on the bridge body by riveting, and the joints between adjacent composite plates Structural glue is injected inside to prevent the bridge deck 7 from leaking; the staircase 11 is formed by overlapping multiple composite boards up and down, and the upper and lower composite boards are connected together by welding.

[0061] Such as Image 6 Specifically, the composite board of this embodiment includes an upper panel 1', a lower panel 2', a number of round tubes 3'in the middle, and a brazing layer 4 between the round tube 3'and the upper panel 1'and the lower panel 2'...

Embodiment 3

[0068] Such as Picture 9 Shown: an arched flyover, which differs from embodiment 1 or embodiment 2 in that it includes a bridge body, a bridge deck 7 and a guardrail 8 arranged on the bridge deck 7. The bridge body includes a column 10, an arched cross beam 9 and The ramp 12 and the column 10 are composed of multiple composite plates stacked by welding; the arched cross beam 9 is composed of multiple arc-shaped composite plates joined by welding; the bridge deck 7 is composed of multiple pieces installed on the bridge by riveting The composite panels on the main body are spliced ​​together, and structural glue is injected into the joints between adjacent composite panels to prevent the bridge deck 7 from leaking; the ramp 12 is composed of multiple pieces connected to the arched beam 9 at one end and fixed at the other end. The composite boards on the ground are spliced ​​together, and the composite boards are connected together by welding.

[0069] Such as Picture 10 Shown: t...

Abstract

The invention discloses a pedestrian overpass. The pedestrian overpass comprises an overpass body, an overpass face arranged on the overpass body and guardrails arranged on the overpass face, the overpass face is composed of one or a plurality of composite plates by splicing, and the composite plates comprise upper panels, lower panels, a plurality of pipe bodies in the middle, and brazing layersbetween the pipe bodies and the upper panels as well as the lower panels. On the one hand, the pedestrian overpass has four functions of heat preservation, fire prevention, sound insulation and vibration isolation; on the other hand, under the same strength, the amount of used material is least; under the same weight, the strength is largest; and the pedestrian overpass has the characteristics ofbeing quick to assemble and disassemble and easy to replace and maintain.

Description

Technical field [0001] The invention relates to an overpass, in particular to a pedestrian overpass. Background technique [0002] The amount of urban pedestrian bridges is huge, which requires simple structure, quick construction, good landscape and economical cost. The steel box girder structure is the most commonly used flyover main girder structure at this stage due to its high rigidity and mature construction technology. The steel main girder and stairway girder have a large amount of engineering and poor economy; the steel box girder has a closed section, small space in the box, inconvenient processing of the steel structure, long installation and construction period, and the closed section form is for later maintenance and Maintenance is inconvenient, and the durability of its steel structure cannot be guaranteed. [0003] Therefore, it is necessary to design a pedestrian bridge that can have the characteristics of high structural strength, low material consumption, and co...
