Abstract
The invention discloses a multi-span rigid frame bowstring arch bridge. The multi-span rigid frame bowstring arch bridge comprises a cross beam, two side piers, a middle pier which is arranged between the two side piers, a main arch rib which connects the side piers and the middle pier and a suspender which connects the main arch rib and a bridge deck slab; the cross beam are upward supported by the two side piers and the middle pier. The multi-span rigid frame bowstring arch bridge comprises a through type tie bar; the tie bar penetrates the two side piers and the middle pier; two ends of the tie bar are anchored on the two side piers. The multi-span rigid frame bowstring arch bridge solves the problem that an impost fastening position of the middle pier of a through type multi-span rigid frame bowstring arch bridge is complex in structure and stress, improves the structural safety, meanwhile reduces the structural size of the middle pier and is good in landscape effect.
Description
Technical field
The present invention relates to a kind of arch bridge, particularly a kind of multispan rigid framed arch.
Background technology
The arch rib of lower support type rigid framed arch and bridge pier are in arch springing place consolidation, and prestress wire is as the horizontal thrust at tie-rod balance arch springing place.Rigid framed arch is divided into single span and multispan, and wherein the tie-rod of multispan rigid-framed tied arch bridges adopts anchoring separately by cross.The shortcoming existed is: 1) structure of the archpier fixed joint of rigid-framed tied arch bridges is comparatively complicated, pier especially, because both sides arch rib, cap etc. converge in here, difficulty of construction is large; 2) archpier fixed joint place is stressed also comparatively complicated, is subject to the concentrated force effect that tie-rod is very large, easily ftractures in principal tensile stress direction.
Summary of the invention
In view of this, the present invention solves pier consolidation place complex structure problem in multispan rigid framed arch, reduces its physical dimension, makes the stressed reduction at impost consolidation place, improves bridge pier degree of safety, promotes landscape effect.
Multispan rigid framed arch of the present invention, comprise crossbeam, two abutment piers, between two abutment piers in pier, connect the major arch rib of abutment pier and middle pier and be connected the suspension rod of major arch rib and bridge deck, described two abutment piers and middle pier upwards supporting traverse, also comprise the tie-rod of elongated type, described tie-rod through two abutment piers and middle pier and two ends be anchored on two abutment piers.
Further, described two abutment piers and Zhong Dun are the consolidation pier together with being cast in crossbeam.
Further, have concrete integument outside described tie-rod, described concrete integument to be located at below bridge deck and to link together with bridge deck.
Further, described tie-rod is made up of a branch of or multi beam prestress wire.
Beneficial effect of the present invention: multispan rigid framed arch of the present invention, comprise crossbeam, two abutment piers, between two abutment piers in pier, connect the major arch rib of abutment pier and middle pier and be connected the suspension rod of major arch rib and bridge deck, described two abutment piers and middle pier upwards supporting traverse, also comprise the tie-rod of elongated type, described tie-rod through two abutment piers and middle pier and two ends be anchored on two abutment piers.This structure solves the impost consolidation place structure of pier in lower support type multispan rigid framed arch and stressed challenge, and improve structural safety, reduce the physical dimension of middle pier, landscape effect is better simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is abutment pier structural representation;
Fig. 3 is middle pier structure schematic diagram.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as shown in the figure: the multispan rigid framed arch of the present embodiment, comprise crossbeam 1, two abutment piers 2,3, between two abutment piers in pier 4, connect the major arch rib 5,6 of abutment pier and middle pier and be connected the suspension rod 7 of major arch rib and bridge deck, described two abutment piers and middle pier upwards supporting traverse, also comprise the tie-rod 8 of elongated type, after described tie-rod 8 is horizontally through two abutment piers and middle pier, two ends are anchored on two abutment piers.In in the present embodiment, the quantity of pier is one, and certainly, the quantity of pier can be multiple, when central pier quantity is multiple, is also connected with major arch rib between adjacent middle pier.Adjacent middle pier and abutment pier, between Zhong Dun and middle pier be one across, it is jointly stressed that elongated type tie-rod 8 makes whole multispan bridge become an entirety, solve the impost consolidation place structure of pier in lower support type multispan rigid framed arch and stressed challenge, improve structural safety, reduce the physical dimension of middle pier, landscape effect is better simultaneously.
As the further improvement of technique scheme, described two abutment piers 2,3 and middle pier 4 are the consolidation pier together with being cast in crossbeam.Consolidation pier limits vertical bridge to slip, greatly reduces the fatigue effect that tie-rod receives, and extends the life-span of tie-rod, improves the durability of bridge.
As the further improvement of technique scheme, have concrete integument outside described tie-rod 8, described concrete integument to be located at below bridge deck and to link together with bridge deck.Make tie-rod 8 whole stressed less, integral bridge structural strength is larger.
As the further improvement of technique scheme, described tie-rod is made up of a branch of or multi beam prestress wire.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
