Abstract
A kind of facade asymmetric space arch arch bridge structure, comprise limit arch rib, middle arch rib, girder, the two ends of limit arch rib, middle arch rib are provided with arch springing, it is characterized in that: the arch springing of described limit arch rib and middle arch rib one end is half-through arch springing, half-through arch springing stretches into the cushion cap of girder bottom, formed with cushion cap and be rigidly connected, between girder and cushion cap, be provided with diagonal brace and the pull bar of connection; The other end is lower support type arch springing, and lower support type arch springing and girder just connect, and arrange under girder along bridge to sliding support.Advantage of the present utility model and beneficial effect: this pontic half is half-through arch bridge, second half is lower bearing arch bridge, and the stress model of half-through part is fixed-end arch consolidation form, and consequent horizontal force is cut down by diagonal brace and pull bar; The stress model of lower support type part is freely-supported slip form, and eliminate the horizontal thrust that arch bridge produces under vertical uniform load q, half-through arch bridge and lower bearing arch bridge are perfectly combined togather by this arch bridge structure.
Description
Technical field
This utility model relates to form of structure field in bridge engineering, specifically a kind of facade asymmetric space arch arch bridge structure.
Background technology
Steel arch bridge can be divided into deck type, half-through, lower bearing arch bridge according to the lane position of arch bridge, runway system (bridge deck) is called deck type on arch rib, the runway system of half-through arch bridge is positioned at the middle part of arch rib rise, under bridge deck part suspension rod is suspended on arch rib, part upright supports is on arch rib, in like manner, the roadway of lower bearing arch bridge is positioned under arch rib and suspension rod.
Built many typical steel arch bridge structures abroad, as the Sydney Harbour Bridge that Australia builds up for 1932, across footpath 503m, the New York shellfish bridge forever that the U.S. builds up for 1934, across footpath 504m, the new river valley bridge that the U.S. builds up for 1977, across footpath 518m.Colored bridge is close in the Soul that Korea S builds up for 2000, across footpath 540m.Domesticly also built many typical steel arch bridges, as the Lupu Bridge in Shanghai to build up for 2003, across footpath 550m, the ChaoTianMen Bridge built up for 2009, across footpath 552m, the Nanjing Foundations of Dashengguan Changjiang River Bridge built up for 2011, across footpath 336m.These arch bridges all have employed conventional symmetrical structure system, with large and well-known across footpath.
Nowadays, along with the needs of civic landscape development, start to have occurred civic landscape arch bridge, compared with large span arch bridge over strait across river with above-mentioned, to cross over valley, civic landscape arch bridge also has oneself feature and technological difficulties, these arch bridges are not won victory in span, but innovate to some extent in the form of structure of bridge, unconventional dissymmetrical structure system is adopted in design and construction, still to there is difficult point to build bridge, these asymmetric bridges represent the design level of current advanced person, and its structural system and construction measure also need to be broken through.
Summary of the invention
Problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of half-through arch bridge structure combination with lower bearing arch bridge structure and the facade asymmetric space arch arch bridge structure formed.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of facade asymmetric space arch arch bridge structure, comprise limit arch rib, middle arch rib, girder, main bridge bridge type is three stride continuous non-thrust arched bridge, facade adopts asymmetric space arch arch bridge structure, limit arch rib, the two ends of middle arch rib are provided with arch springing, according to limit arch rib, the position relationship of middle arch rib two ends arch springing and girder, arch bridge both sides are divided into half-through structure, lower support type structure, the half-through arch springing of described limit arch rib and middle arch rib one end stretches into the cushion cap of girder bottom, formed with cushion cap and be rigidly connected, and between girder and cushion cap, be provided with diagonal brace and the pull bar of connection, to cut down the horizontal force of beam stress and adjacent arch springing, for the form of structure of half-through arch bridge, the lower support type arch springing of the other end and girder just connect, and arrange under girder along bridge to sliding support, release arch bridge horizontal force is the form of structure of lower bearing arch bridge.
The utility model compared with prior art has significant advantage and beneficial effect:
From space facade, this bridge half is half-through arch bridge, and second half is lower bearing arch bridge, and the arch springing of main span half-through part stretches into infrastructure formation and is rigidly connected, and its stress model is fixed-end arch consolidation form, and consequent horizontal force is cut down by diagonal brace and pull bar, after the arch springing of lower support type part and bridge floor beam body just connect, arrange under girder along bridge to sliding support, the stress model supported is freely-supported slip form, the horizontal force of main arch is born by girder, eliminate the horizontal thrust that arch bridge produces under vertical uniform load q, this facade asymmetric space arch arch bridge structure form provides a kind of effective embodiment, half-through arch bridge and lower bearing arch bridge are perfectly combined togather, not only make arch bridge use under complex geological condition and become possibility, also be a kind of innovation adapting to new city view arch bridge system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein 1, limit arch rib, 2, middle arch rib, 3, half-through arch springing, 4, lower support type arch springing, 5, girder, 6, cushion cap, 7, diagonal brace, 8, pull bar, 9, sliding support.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to detailed description of the invention, structure, feature and effect thereof of providing according to the utility model, be described in detail as follows.
A kind of facade asymmetric space arch arch bridge structure as shown in Figure 1, comprise limit arch rib 1, middle arch rib 2, girder 5, main bridge bridge type is three stride continuous non-thrust arched bridge, facade adopts asymmetric space arch arch bridge structure, limit arch rib 1, middle arch rib 2 is horizontally disposed with girder, limit arch rib 1, the two ends of middle arch rib 2 are provided with arch springing, according to limit arch rib 1, the position relationship of middle arch rib 2 two ends arch springing and girder 5, arch bridge both sides are divided into half-through structure, lower support type structure, the half-through arch springing 3 of one end stretches into the cushion cap 6 of girder bottom, formed with cushion cap 6 and be rigidly connected, and between girder 5 and cushion cap 6, be provided with diagonal brace 7 and the pull bar 8 of connection, to cut down the horizontal force of beam stress and adjacent arch springing, for the form of structure of half-through arch bridge, lower support type arch springing 4 and the bridge floor girder 5 of the other end just connect, and girder arrange for 5 times along bridge to sliding support 9, release arch bridge horizontal force is the form of structure of lower bearing arch bridge.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
