Abstract
The utility model discloses a combined prestressing hanging bridge. The utility model comprises a hanging bridge; the two ends of the hanging bridge are provided with a tower pole(1); the tower pole(1) is provided with a prestressing rope(5); the bridge surface(4) of the hanging bridge is connected with the prestressing rope(5). The utility model adopts the prestressing rope to enhance the stability of the hanging bridge; the utility model adopts the tower pole base of the two banks of the hanging bridge as the fixing base of the prestressing rope anchor; and the utility model needs no fixing base to exert the prestress. Compared with the prior hanging bridge, the project construction cost increases little and has a high stability; the position of the prestress component is on the bridge table and will not be influenced by the terrain and the water level; and the utility model is convenient to be constructed. The utility model is applicable to the walking hanging bridge and the submerged bridge of the reservoir basin; and the utility model has a large market.
Description
Technical field:
The utility model relates to a kind of combined prestressed drawbridge, belongs to large span People's Bank of China suspension bridge technical field.
Background technology:
Because three plate stream storehouses are built up, Jianhe County, clear water river section water level rises 50 meters, and many small towns, number county original paths such as Guizhou Jianhe are submerged.Masses' dealing and student go to school and are broken by water resistance, must construct a bridge.Because the restriction of construction costs can only be built pedestrian bridge, span does not wait from 100 meters to 320 meters, and bridge floor is wide only 2 meters, and width 1/50～1/160, longeron are rail.Consider that livestock also will pass a bridge, therefore higher to the stability requirement of bridge.People's Bank of China of the prior art its structure of suspension bridge is generally at the two ends, riverbank builds king-post, connect main rope on the king-post, main rope connects the bridge floor of suspension bridge by suspension rod, the width of suspension bridge is usually in 1/30, when the span of suspension bridge surpasses 150 meters, the wind resistance rope that this bridge is general can not satisfy vertical and the lateral stability requirement, understands and must be rocked by wind, even suspension bridge blown turn over.In order to improve the stability of suspension bridge, if suspension bridge adopts horizontal wind resistance rope to launch in the both sides of bridge, from the plane, because bridge site is generally narrow in the river course, the two sides salient position, the wind resistance rope can't set up sometimes.If arch (promptly from bridge under the anti-rope that draws one) adopted open by suspension bridge, increase vertical rigidity, the place can adopt at the dry river ditch, and reservoir is then not all right.Because bridge floor is apart from the water surface very near (as raise bridge floor, span increases many), vang is fallen with regard under water in a position that not have down to open arch not so, from opening the navigation or air flight and requirement for anticorrosion does not allow.
Summary of the invention:
The purpose of this utility model is: the combined prestressed drawbridge that a kind of cost is lower, be suitable for the suspension bridge construction of large span People's Bank of China is provided.
Combined prestressed drawbridge of the present utility model is, it comprises suspension bridge, and the two ends of suspension bridge are provided with king-post (1), are provided with prestressed cable (5) between king-post (1), and the bridge floor of suspension bridge (4) links together with prestressed cable (5).
Above-mentioned combined prestressed drawbridge, king-post (1) is gone up and is connected main rope (2), main rope (2) is by the bridge floor (4) of suspension rod (3) connection suspension bridge, and in suspension rod (3) each junction with bridge floor (4), bridge floor (4) is fixed together by folder (6) and prestressed cable (5).
Above-mentioned combined prestressed drawbridge is provided with prestressed cable anchor (7) at the suspension bridge two ends, connect prestressed cable (5) between the prestressed cable anchor (7).
Above-mentioned combined prestressed drawbridge is provided with prestressed cable anchor (7) on the king-post (1) at suspension bridge two ends, connect prestressed cable (5) between the prestressed cable anchor (7).
The utility model adopts prestressed cable to improve the stability of suspension bridge, utilizes the immobilizing foundation of the king-post basis of suspension bridge two sides as the prestressed cable anchor, need not build immobilizing foundation in addition, can apply prestressing force.Compare with existing suspension bridge, construction costs increases little, and stability is high, and the prestressing force position component is not subjected to the influence of landform and water level at the abutment place, and it is comparatively convenient to construct.Be applicable to People's Bank of China's suspension bridge of large span, flood at the reservoir basin and go back bridge that bigger market is arranged.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the A-A sectional view of accompanying drawing 1.
The specific embodiment:
Embodiment of the present utility model: adopt existing suspension bridge design, produce king-post (1) at the two ends, riverbank of building suspension bridge, king-post (1) is gone up and is connected main rope (2), one end of main rope (2) connects anchor ingot (11), imbed in the massif (10), main rope (2) is born the gravity of bridge floor (4) by the bridge floor (4) of suspension rod (3) connection suspension bridge, connect prestressed cable (5) between the king-post (1) at suspension bridge two ends, bridge floor (4) links together with prestressed cable (5).Improve the horizontal and vertical stability of suspension bridge by prestressed cable (5), and the cost of making prestressed cable (5) is low, is applicable to People's Bank of China's suspension bridge of large span.
The prestressed cable of suspension bridge (5) design all can in top, the below of bridge floor (4), produce the basis at the suspension bridge two ends, fix prestressed cable anchor (7), connect prestressed cable (5) between the prestressed cable anchor (7), also prestressed cable anchor (7) can be squeezed in the massif (10).In order to save cost, can directly adopt the basis of the basis of king-post (1) as prestressed cable anchor (7), on the basis of the king-post (1) at suspension bridge two ends, produce prestressed cable anchor (7), connect prestressed cable (5) between the prestressed cable anchor (7).When building, prestressed cable (5) can be installed in longeron (8) below of bridge floor (4), the crossbeam (9) for walking usefulness is installed in longeron (8) top, suspension rod (3) is fixed on the longeron (8), in suspension rod (3) each junction with bridge floor (4), bridge floor (4) is fixed together by folder (6) and prestressed cable (5), when about bridge floor, when teetertottering, because the existence of prestressed cable (5), can reduce the amplitude that suspension bridge rocks, improve stability, improvement value is relevant with the tension force of prestressed cable (5), can be calculated by designing requirement and determine.
Large-scale suspension highway bridge road bridge bridge floor broad, general 9～28 meters, longeron rigidity is very big, normally steel case beam, steel truss beam and prestressed concrete beam, from great, width is no more than 1/40 generally 1/25～1/35.These bridges can solve stable problem by the rigidity of longeron self.Can adopt the combined type form of drawing of hanging in case of necessity, as the Wujiang River, Guizhou bridge.So technology of the present utility model is not suitable for suspension highway bridge, it is big to be suitable for span, and the lower-cost People's Bank of China of cost suspension bridge.
