Abstract
The invention provides a through triangular truss steel bridge with an externally-hung mooring channel. The through triangular truss steel bridge with the externally-hung mooring channel comprises three chord members parallel to one another, wherein the three chord members are divided into two lower chord members and one upper chord member according to spatial positions, supporting rods used for supporting are welded between every two adjacent parallel chord members, and connected end to end to form a plurality of supporting faces which are of triangular structures, three supporting faces are spliced into a firm triangular truss space stress system, the outer side of one of the lower chord members is provided with the externally-hung mooring channel extending in the direction of the lower chord member, and the perpendicular orthographic projection of the upper chord member on the supporting face at the bottom is located at the eccentric position and close to the side with the externally-hung mooring channel. The through triangular truss steel bridge with the externally-hung mooring channel has the advantages of being safe, reliable, convenient to use, low in manufacturing cost, simple, attractive, convenient and fast to construct, better in corrosion resistance, longer in service life and convenient to disassemble and replace.
Description
Technical field
The present invention relates to steel structure bridge technical field of construction, refer more particularly to a kind of lower support type English truss and be linked with cable passage steel bridge outward.
Background technology
Development along with port works is built, increases across steel work band cable passage steel bridge application demand greatly in the district of port.Traditional truss-like, arch purlin formula band cable steel bridge, lack the overall planning to the use function of structure, construction costs, construction convenience, working service performance, is difficult to accomplish that economical rationality takes into account construction convenient.
Traditional parallel chord truss formula steel bridge, the main stressed member of truss is welded by shaped steel, and piece table area is large and have the more close gap that is difficult to maintenance, is unfavorable for durability and the operating period maintenance of structure for harbour engineering; Tradition arch purlin formula steel bridge, scantling is various, cross section is thin, all more unfavorable to construction and working service for harbour engineering; Tradition band cable steel bridge arranges two and is independently with cable passage, walkway, and with respect to being mainly the passage bridge arranging with cable object between harbour engineering pier and pier, it is larger that bridge floor functional areas arrange burden, materials waste and maintenance cost.
Summary of the invention
Technical problem to be solved by this invention is the technical deficiency over against above-mentioned existence, provide a kind of safe and reliable, easy to use, cheap, succinctly attractive in appearance, the lower support type English truss easily of constructing is linked with cable passage steel bridge outward.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of lower support type English truss is linked with cable passage steel bridge outward, it is characterized in that: comprise three chord members that are parallel to each other, three strings pole-footing is divided into two lower chords and a upper chord according to locus, between every two parallel chord members, be welded with the strut supporting, strut between every two parallel chord members joins end to end, form the supporting surface of a plurality of triangular structures, three supporting surfaces are combined into firm triangular truss space-load system; Outside the outside of in described lower chord, hang with the band cable passage extending along lower chord direction; Described upper chord is in the vertical orthography of bottom support face, in eccentric position, and near being linked with cable passage one side outward
In such scheme, what the strut between described chord member and chord member adopted is to pass through mutually directly welding of weldering.
In such scheme, described includes the in length and breadth beam of bottom for supporting with cable passage, and is arranged on the bridge floor above beam in length and breadth.
In such scheme, described beam in length and breadth includes the supporting surface structure of passage crossbeam and passage longeron composition, and beam and lower chord directly weld in length and breadth.
In such scheme, the described bridge floor with cable passage is horizontal plane, and bridge floor is set to removable steel grating structure, and in bridge floor both sides, railing is installed.
In such scheme, described chord member and strut are hollow round steel pipe.
Beneficial effect of the present invention is:
1, main stress member is lower support type parallel chords steel pipe triangular truss.English truss space-load system, can provide enough bending resistance, torsional rigidities with cable passage for plug-in.
2, English truss number of components is few, is conducive to construction and operating period maintenance.
3, band cable passage is hung on outward outside English truss lower chord, and unites two into one with walkway, makes structure design more economical, succinct, reasonable.
4, English truss and band cable passage in length and breadth beam be steel tube section, exposed surface area is minimum, the reserved rational corrosion thickness of design period also provides the anticorrosion scheme of paint, can ensure total life cycle structural safety, and requires necessary engineering cost minimum because of corrosion.
6, band cable passage bridge floor is changeable type steel grating, can in the operating period, provide more rationally safety guarantee reliably for structure.
