Abstract
The invention belongs to the technical field of building structure, which discloses a vertical steering steel-concrete combined arch bridge. The main implementation steps are as follows: steel box arc segments are assembled at the skewback vertically and concrete in the arch springing segment steel box is filled to form an upright semi-cross steel box arc bent frame; the steel box arc bent frame rotates around the lower end slowly to the span centre for folding to be coupled with an arch; the constructions of arc concrete beam and cross section steel box arc top concrete are finished to form integral steel-concrete combined arch structure; the constructions of bridge abutment, arch upright post and bridge deck are finished to form a whole bridge. The main arch structure is characterized in that the arch springing segment is an arch rib filled with concrete in the steel box, and the cross segment is a steel-concrete combined arch structure cast with concrete on the steel box top; ribbed stiffener boards of the steel box bottom and ventral shield besides the arch spring segment are all installed inside the steel box, and the stiffening plate on the top is installed on the steel box top by holing the ribbed stiffener boards and is also taken as a PBL shearing force bond of concrete combined with the steel box top board.
Description
The invention belongs to the building structure technology field, relate in particular to a kind of vertical rotation steel-concrete combination arch bridge.
In the prior art, long-span arch bridge commonly used mainly contains concrete arch-type bridge and concrete-filled steel tubes arch bridge.Concrete arch-type bridge has economical and practical, attractive in appearance durable advantage to alpine terrain, its traditional job practices adopt segmented prefabricated, the antenna handling is in place, free cantilever erection closes up and forms its main arch structure piecemeal, need huge prefabricated handling place, large-scale plant and complicated main push-towing rope, knotted rope, unrestrained wind system, there are many unsafe factors in the cantilever structure in the work progress, complex process, operation is various, technical difficulty is big, measure cost is high, the construction period is long; The concrete-filled steel tubes arch bridge that last century end grows up has overcome above-mentioned shortcoming to a certain extent, but owing to structure, stressed and technical reason, span is not had economic advantages at 200 meters with interior Deck Arch Bridges.
The object of the present invention is to provide a kind of simple in structure, quality is easily protected, construction safety, convenient, fast, required construction plant and plant require lower, to building span under the condition of mountain area at 200 meters vertical rotation steel-concrete combination arch bridges that have obvious comprehensive technology economic advantages with interior arch bridge.
Purpose of the present invention realizes with following technical step: A, the steel box arch rib of floor and steel diaphragm of in floor, case are put more energy in factory's perforate that segmented making comprises the steel roof box by designing requirement, putting more energy into, and be transported to the bridge scene; B, at two sides abut place respectively along the vertical arch springing segment steel case arch rib of installing, its lower end with remake the temporary consolidation disposal after abut is connected by rotating hinge; C, in arch springing segment steel case, fill out concrete placing,, and finish the installation of respective steel lateral ties synchronously, form upright semi-cross steel case arch framed bent again along vertical all the other upper segment of jointing steel box arch rib piecemeal; D, hitch steel case arch framed bent, remove the steel box arch rib lower end and be reduced to rotating hinge with the temporary consolidation of abut and be connected, control the speed of loosening of steel cable, make the steel case of two sides encircle framed bent and slowly turn to span centre around rotating hinge and close up and be coupled to arch with steel cable; E, cast-in-place envelope hinge concrete make the steel box arch rib after closing up become the fixed Ecardines case arch structure in two ends; F, build steel case inner bottom plating concrete in case of necessity, finish the construction of concrete straining beam between arch rib, build steel box arch rib top layer concrete and form whole steel-concrete combination arch structure; G, the construction of finishing abutment, spandrel column and bridge deck form full-bridge.
The structural feature of main arch structure of the present invention is: the arch springing section of A, main arch structure is completely to fill out concrete steel-concrete combined structure in the steel box arch rib of square-section; The span centre section of B, main arch structure requires have three kinds of sectional forms selective according to stressed or structure: 1) form steel-concrete combination Ribbed Arch Structure at steel box arch rib end face concreting respectively; 2) form steel case-concrete slab built-up arch structure at steel box arch rib end face monobloc cast concrete slab; 3) in steel box arch rib, build underplate concrete, form whole steel-concrete combination arch structure at steel box arch rib end face monobloc cast concrete slab again; Be transition zone between C, arch springing section and the span centre section, be gradually varied to empty van or underplate concrete is only arranged by completely filling out concrete in the steel box arch rib, the concrete width in steel box top by with the steel case with the wide setting width that is gradually varied to; The floor of putting more energy into of D, the steel box plate except that the arch springing section and web is located at steel case inboard, the floor of putting more energy into of steel roof box is located on the steel case end face, this floor of putting more energy into is the perforate steel plate of putting more energy into, pass the perforate floor of putting more energy into and become the PBL shear connector that concrete and steel roof box connect to water reinforcing bar in the top concrete after an action of the bowels, steel case inner bottom plating is if need concreting, and then the floor of putting more energy into of steel box plate also should adopt the perforate steel plate of putting more energy into; Every suitable spacing the steel diaphragm is set in E, the steel box arch rib; F, the arch rib place below column are provided with the steel concrete straining beam; Completely fill out concrete in the local steel case of the arch rib of G, column below, so that the reinforcing bar of concrete straining beam stretches into anchoring in the steel case concrete, the while is as the stiffness diaphragm of steel case.
The good effect that the present invention has is: the batch production section is made steel case arch sections, is easy to guarantee fabricating quality; At abut place vertical jointing steel box semiarch framed bent, save the construction plant; Vertical transfer steel case semiarch framed bent closes up, and need not heavy cable lifting, knotted rope and unrestrained wind system, becomes arch safety, quick; To become the steel box arch rib behind the arch to build top board (with the steel case inner bottom plating) concrete of main arch structure, can save a large amount of supports and template as bed die or support; Compare with steel arch bridge, can save great deal of steel, reduce cost; After water the integral rigidity that the main arch concrete helps strengthening the main arch structure, improve the usability and the durability of bridge.Arch bridge construction under the condition of mountain area had tangible comprehensive technology economic advantages.
