Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
nullShown in Fig. 3，Non-self-balancing type steel truss long-span arch bridge，Including left pontic 1 and right pontic 2，Connected by span centre linkage section 3 between left pontic and right pontic，Span centre linkage section includes top boom 4、Lower boom 5 and diagonal web member 6，Top boom、Lower boom and diagonal web member are all with left pontic axle even，And it is welded and fixed with right pontic，Left pontic and right pontic are arranged at corresponding bridge rotating 7 top，Bridge rotating includes base platform 8，Base platform surface configuration has lower millstone 9，Lower millstone surface configuration is taper surface，And middle part is provided with centre strut 10，The base platform of lower millstone periphery is additionally provided with a circle slideway 11，Slideway abuts and is provided with some buttresses 12，Lower millstone is additionally provided with top rotary table 13，The groove consistent with the shape that lower millstone and centre strut cooperatively form it is provided with bottom the top rotary table that lower millstone is corresponding，Also it is connected with buttress top bottom top rotary table，Overhead space 14 it is provided with bottom top rotary table and between base platform，Top rotary table top is provided with bridge pier 15，Pier coping portion is provided with ball bridle iron 16.
Span centre linkage section as shown in fig. 1, becomes incline direction arrangement, coordinates off-axis setting even, ensure that when construction, it is possible to be directly lifted on bridge, directly put down after integral-rotation displacement and can connect, construction does not affect lower section vehicle and navigates, and can improve behaviour's efficiency.
Wherein, sliding panel it is fixedly installed bottom buttress, sliding panel material is politef, top rotary table is the mechanism that turns, the buttress of its connection acts on slideway, the strong point of the mechanism that turns as core in pontic rotation process, is provided with sliding panel in the bottom surface of buttress as break-in medium, for reducing the coefficient of friction resistance of buttress and slideway, reduce the resistance of pushing tow process.
Sealing coat 17 it is additionally provided with between lower millstone and top rotary table, sealing coat material is paraffin, it has primarily served buffer action, when top rotary table waters, lower millstone will not be touched, avoid the later stage to rotate the friction that directly contact occurs, secondly also when lower millstone and top rotary table rotate, play the effect reducing frictional force.Lubricating layer 18 it is additionally provided with between sealing coat and top rotary table, lubricating layer material is butter, this lubricating layer is mainly used in lubrication, reduce frictional force, ensure the effectiveness that lower millstone and top rotary table rotate, secondly it also acts centrifugation, it is to avoid during top rotary table pouring, concrete causes adhesion with the lower millstone of lower section paraffin and pouring molding.
Lower millstone side arranges and loses round shading ring 19, losing circle shading ring material is paraffin, when construction, the prototype structure side of lower millstone cannot accomplish perfection, top rotary table pouring time also cannot control, by losing the preparation of round shading ring, expand the diameter of top rotary table, avoiding causing stuck phenomenon when rotating because losing circle, it can effectively reduce construction precision, reduces difficulty of construction.
The material of base platform, lower millstone, top rotary table and buttress is armored concrete, reduce construction cost, the material of centre strut is Z45 steel, owing to centre strut is as the support parts in bosom, its intensity needs high, and need to mix open with concrete material, not easily be sticked together, thus reach the purpose that once pouring can be implemented to rotate.
Left pontic and right pontic upper berth are equipped with bridge floor, and bridge floor material is methacrylic resin, have anti-skidding, wear-resisting etc. a little.
Left pontic and right pontic top are provided with safety glass awning 20, it is provided that effectively daylighting, and transparent material is elegant in appearance, it is also possible to as the instrument of taking shelter from rain.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model.The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein when without departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
