Description
Technical field
The present invention relates to bridge technology field, particularly relate to the combination of a kind of spacial special-shaped lattice based on winding system tiltedly
Draw steel construction arch bridge.
Background technology
At present in the design of urban look foot bridge, typically the bridge across footpath is frequently with beam bridge, rigid frame bridge, arch bridge, purlin
Building bridge, the urban look foot bridge of Long span then uses cable-stayed bridge, suspension bridge and combined system birdge (Yi Liang, to encircle, hang three
Various combination be main) version.
Common urban look foot bridge version is all to develop from highway bridge, although note in evolutionary process
The moulding of bridge upper body of having anticipated, it is also considered that pier and the coordination aesthetic property of superstructure combination, has sought bridge itself
The coordination of collocation of colour and around natural or artificial color, also carries out suitable decoration to railing, pier, girder, Sarasota etc., but
All the time creative breakthrough is not formed.
Such as, document CN 202164533U discloses one can to cross over urban road current for pedestrains safety and increase
Existing city is across the arch cross-street footbridge of street bridge landscape function, welded with abutment (15) with two groups of arcs steel structure (1)
Or connecting method composition carries structure across the bridge floor of street bridge, below the bridge floor carrying structure of composition, it is fixed on abutment with bolt (14)
On plinth, Bridge Deck Steel (3) laterally rides in carrying girder steel (4), and the circular steel plate (5) in junction mixes bolt (6), by arc
Arch steel structure (1), Bridge Deck Steel (3) and abutment (15) are fixing to be reinforced.Arc steel structure and Bridge Deck Steel bolt (2) tighten up solid
Fixed, with supporting abutment (7) supporting below Bridge Deck Steel two ends, ladder step carries girder steel (8) welding or bolt connecting method up and down
Being overlapped on Bridge Deck Steel, below with ladder fore-and-aft gangway base steel structure (13) supporting, bridge floor is laterally and steel plate is taken on ladder step carrying girder steel upper berth
(9,12), ladder step steel plate installs pedestrian's upper and lower bridge ladder step (10) and upper and lower bridge of pedestrian and bridge floor handrail (11) constitute arc across
Street foot bridge.
Document CN104404862A discloses a kind of steel pipe rack People's Bank of China Pipeline Bridge, including have People's Bank of China's bridge floor fasten layer and
Pipeline/and the bridge of access path lower floor, described bridge main beam is tubular net frame structure；Girder is by multiple full-length steelpipe nets
Shelf structure forms, and space is divided into upper and lower two-layer by floorings, and upper strata is walkway, and lower floor is pipeline and access path；Steel pipe
Rack inner space is bigger, it is achieved that pedestrian separates up and down with pipeline, it is ensured that each separate space, conveniently uses and manages
Reason；Girder is made up of the grid structure of full-length, belongs to modularized design, and processing and fabricating can mass.Described girder is by many
The steelpipe net shelf structure that individual annular steel disc 2 and the circumferentially fixed steel pipe 1 connecting annular steel disc 2 are formed；Steel pipe 1 is fixedly connected on steel
On sheet 2, steel pipe 1 and steel disc 2 form tubular net frame space；Girder is indulged bridge and is arranged one annulus steel disc 2 (i.e. one mark to 3.5m section
Quasi-grid structure length)；Steel pipe net rack installation is big, bearing capacity is high, it is adaptable to intensive people flow and the demand that crosses the river of large-scale pipeline.Institute
State the radially fixed crossbeam 5 being provided with for supporting upper strata People's Bank of China bridge deck 4 of steel disc 2；" radially " it is steel disc 2 diametric(al), horizontal
Rack space is divided into upper and lower two-layer by beam 5, and upper strata is walkway, and lower floor is pipeline and access path, can add in steel disc 2 local
Flange plate, forms crossbeam 5, as bridge deck supporting construction.Described steel pipe 1 and steel disc 2 is welded and fixed by gusset plate 3 and is connected；
