Abstract
A cable-girder anchorage structure of a railway steel truss cable stayed bridge has the advantages of being even in stress, short in force transmitting route, safe and simple and comprises a steel anchor box (10) with a pair of anchor pulling plates (11 and 12). The anchor pulling plates (11 and 12) are connected with upper chord gusset plates (20) arranged on two sides of a main truss through a splice plate (30) and high strength bolts. Steel sleeves (N8) for stayed cables to penetrate are fixedly arranged inside the steel anchor box (10), and stayed cable axes of the steel sleeves (N8) are crossed with central lines of pitch points of the main truss and upper chord system lines.
Description
Technical field
The utility model relates to the Railway Steel Truss cable stayed bridge, particularly a kind of steel purlin cable stayed bridge cable beam anchoring structure.
Background technology
Modern cable stayed bridge from the seventies in last century since China begins to build, obtained to develop rapidly over 30 years, built up seats up to a hundred so far.And the development of Railway Cable-stayed Bridge is very slow.In recent years, paces have been accelerated in railway construction, have proposed the cable stayed bridge scheme in the bridge project study of some ew lines, and particularly carrying out of Beijing-Shanghai High-Speed Railway previous work deeply carried out the design studies work of Railway Cable-stayed Bridge.The Railway Cable-stayed Bridge research span of being carried out has at present covered the scope from more than 200 meters to more than 600 meters, and the carrying out of these research work is for the construction and the development of Railway Cable-stayed Bridge provides good theoretical foundation and necessary technology deposit.
Up to now, the Railway Cable-stayed Bridge of building up in the world is few in number.The Federal Republic of Yugoslavia Belgrade city savart river bridge that built up in 1980 is heavily loaded Railway Cable-stayed Bridge, span 250m; Japan the 2,000 bent Chuan Qiao is the railway low-pylon cable-stayed bridge, 134 meters of main spans.The maximum span of the domestic highway and railway bi-purpose cable-stayed bridge that has built up is 504 meters (Wuhan Tian Xingzhou Yangtze Bridge, four-track line adds the six-lane highway double bridge), Tongling Yangtze Bridge main span of building reaches 630 meters (four-track line adds the six-lane highway double bridge), the maximum span of the external highway and railway bi-purpose cable-stayed bridge that has built up is Denmark's Oresund bridge, and main span is 490 meters.
The cable beam anchoring of cable stayed bridge is the important force transmission mechanism of cable stayed bridge, and the processing of details herein will directly influence the safety of full bridge structure, and cable beam anchoring unavoidably can produce the cross section of girder and weaken or influence.Anchorage node is positioned at bridge floor when above, and power transmission is direct, makes, check and install all comparatively conveniently, but because the gusset plate that winds up stretches out bridge floor, causes bridge deck discontinuous; When anchorage node was positioned at intra-node, because the intranodal narrow space, execution conditions were poor, welded crisscrossly, caused manufacturing, installation, maintenance, maintenance difficulty; When anchorage node is positioned at the bottom of gusset plate, is easy to processing and safeguards, but truss form is had relatively high expectations, the general N type truss that adopt more.
The utility model content
Technical problem to be solved in the utility model provides a kind of Railway Steel Truss cable stayed bridge cable beam anchoring structure, have stressed evenly, Path of Force Transfer is short and safe and simple characteristics.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Railway Steel Truss cable stayed bridge cable beam anchoring of the present utility model structure, it is characterized in that: it comprises the steel anchor box with a pair of anchor arm-tie, this is connected by scab and high-strength bolt and the main truss both sides gusset plate that winds up the anchor arm-tie; Be set with the steel sleeve that passes for suspension cable in the steel anchor box, the suspension cable axis of steel sleeve and main truss node center line, the system line of winding up cross.
The beneficial effects of the utility model are, compare with existing cable beam anchoring structure, and weld seam is less, stressed rationally, clear and definite, applied widely.Except that anchor plate, riser and anchor arm-tie adopt the thicker steel plate as main primary structure member, steel sleeve, demarcation strip, lamina tecti and bottom plate can adopt thin steel plate, and economical with materials helps reducing construction costs.
Description of drawings
This manual comprises following three width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model Railway Steel Truss cable stayed bridge cable beam anchoring structure;
Fig. 2 is the sectional view along A-A line among Fig. 1;
Fig. 3 is the sectional view along B-B line among Fig. 1.
Component shown in the figure, toponym and pairing mark: steel anchor box 10, anchor arm-tie 11, anchor arm-tie 12, the gusset plate 20 that winds up, lamina tecti N4, riser N2, demarcation strip N3, bottom plate N5, stiffening rib N6, anchor plate N7, steel sleeve N8, scab 30.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, Railway Steel Truss cable stayed bridge cable beam anchoring of the present utility model structure, it comprises the steel anchor box 10 with a pair of anchor arm- tie 11,12, this is connected by scab 30 and high-strength bolt and the main truss both sides gusset plate 20 that winds up anchor arm-tie 11,12.Be set with the steel sleeve N8 that passes for suspension cable in the steel anchor box 10, the suspension cable axis of steel sleeve N8 and main truss node center line, the system line of winding up cross, and the power transmission process is clear and definite, and force path is brief.
With reference to Fig. 2 and Fig. 3, described steel anchor box 10 also comprises the groined type structure that is made of a pair of demarcation strip N3 and a pair of riser N2, the transverse ends of riser N2 and 11,12 welding of anchor arm-tie.Be welded with anchor plate N7 and bottom plate N5 on the front end of described groined type structure, be welded with lamina tecti N4 on the rear end, bottom plate N5, lamina tecti N4 and the box structure that seals with 11, the 12 welding formation of anchor arm-tie.Steel anchor box 10 inner complete closed have solved the anticorrosion problem of steel anchor box 10 inside well.Described steel sleeve N8 passes bottom plate N5, lamina tecti N4 and is fixedly welded on it.Described riser N2 outer surface is provided with stiffening rib N6, and stiffening rib N6 and riser N2, anchor plate N7 welding to strengthen the stability of riser, make member stress more reasonable.
The utility model cable beam anchoring structure is distributed to the concentrated force that transmits from prestressed anchor on the riser N2 uniformly by anchor plate N7, be passed to again on the anchor arm- tie 11,12, evenly be passed on the integral node plate of steel truss girder upper chord by high-strength bolt at last, the combined type Force transmission parts simple structure of cable beam anchoring structure, force path is shortened, power has guaranteed the excessive local distortion of the unlikely generation of each member of anchoring structure in the inner evenly transmission of anchoring structure.The stability that demarcation strip N3, stiffening rib N6 strengthen riser is set on the riser of anchoring structure, makes member stress more reasonable.
Some principles of the above the utility model Railway Steel Truss cable stayed bridge cable beam anchoring structure that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
