Abstract
The utility model discloses a novel able saddle for a diagonal bridge. A plurality of wire dividing tubes are arranged in the novel able saddle, wherein a steel cable set consisting of a plurality of steel cables is arranged in the wire dividing tubes in a penetrating manner; and the outer surfaces at the two sides of the steel cable set are resisted against the inner walls at the two sides on the bottom of each of the wire dividing tubes. According to the novel cable saddle disclosed by the utility model, the shapes of the sections of the wire dividing tubes are changed, so that self-locking force can be generated by the wire dividing tubes and the steel cables which are arranged inside the wire dividing tubes, and the sliding can be avoided without installing anti-skidding devices at the two ends of each of the wire dividing tubes; and moreover, epoxy resin does not need to be poured to the wire dividing tubes, so that the wire dividing tubes are greatly convenient to use and change, thereby saving the bridge constructing cost and being suitable for diagonal bridges of different structures and sizes.
Description
Technical field
The utility model belongs to the road and bridge technical field, is specifically related to a kind of cable-stayed bridge saddle, particularly a kind of cable-stayed bridge saddle with novel sub-wire tubular structure.
Background technology
Along with carrying forward vigorously of China's infrastructure, exist a large amount of super-huge bridges in the development of highway construction, in this bridge design, most cable stayed bridge is comprised of basic components such as bridge tower, cable wires.Referring to Fig. 1, early stage cable stayed bridge is that upper end cable wire 2 is anchored in the bridge tower 1 of bridge, and the lower end is anchored on the cast-in-place prestressed beam slab, and the upper end is anchored at the upper part of bridge tower 1, its stressed horizontal F2 and vertical stress component F1 of being divided into.The horizontal component of bridge tower 1 has serious destruction to bridge tower 1.In order to prevent the destruction of horizontal component, general design and the increase amount of reinforcement that strengthens the tower seat that all adopt causes the raising of cost.Moreover because cable wire 2 is anchored on the Sarasota body 1, reach year in limited time when the application life of cable wire 2, change also very trouble.
Be anchored at the horizontal component that produces on the bridge tower in order to solve cables, the designer is anchored at the mode (referring to Fig. 2) that mode on the bridge tower 1 changes over cable saddle with cable wire 2, exactly pipe is one by one passed required radius according to cable wire 2 at bridge tower 1, be bent into circular minute fiber tube 3 (referring to Fig. 3), then in groups be made into cable saddle 4 (referring to Fig. 4), be cast in the bridge tower 1.Cable wire 2 is passed one by one circular minute fiber tube 3, two ends are anchored on the bridge board again.Slide in order to prevent that cable wire 2 from dividing in the fiber tube 3 in circle, divide fiber tube 3 two that an anti-skidding cutting ferrule respectively is installed in circle; For preventing that cable wire 2 from dividing corrosion in the fiber tube 3 in circle, dividing in circle usually can casting epoxy resin in the fiber tube 3.Although this design has solved cables and has been anchored at the defective that produces horizontal component on the bridge tower, but its weak point is: this kind cable saddle uses very inconvenient, anti-skidding reliability at the side cable wire also is restricted, and only limits to use picture for example just cannot use on this type of the super-huge bridge of the Yangtze Bridge at small-sized cable stayed bridge.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to use, cost is low, cling property good, New Cable-stayed Bridge cable saddle applied widely.
A kind of New Cable-stayed Bridge cable saddle, in be provided with some minutes fiber tubes, be equipped with the cable wire group that is consisted of by some cable wires in described minute in the fiber tube; Two side external surfaces of described cable wire group support and are located on the two bottom sides inwall of minute fiber tube.
Preferably, described minute fiber tube is droplet-shaped.
Preferably, the angle of described minute fiber tube two bottom sides inwall is 60 °.
Preferably, described minute fiber tube is located in and is filled with C50 in close concrete saddle body.
The utility model is by transforming the cross sectional shape of minute fiber tube, make its can be installed in its inner cable wire and produce self-lock force, need not just can avoid producing slip at a minute fiber tube two ends installation of anti-skid devices, need not casting epoxy resin in minute fiber tube, very convenient in using and changing, greatly save the bridging cost, and can be suitable for the cable stayed bridge of any structure size.

The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for explanation the utility model but not for limiting scope of the present utility model.
Embodiment 1
Referring to Fig. 5, Fig. 6, a kind of New Cable-stayed Bridge cable saddle 4 ' that the utility model provides, in be provided with some droplet-shaped and divide fiber tube 3 ', described droplet-shaped is divided and is equipped with the cable wire group 2 ' that is made of some cable wires 2 in the fiber tube 3 ', and two side external surfaces of described cable wire group 2 ' support and are located at droplet-shaped and divide on the two bottom sides inwall of fiber tube 3 '.
By utilizing droplet-shaped to divide two contract faces of fiber tube 3 ' bottom, cable wire 2 can be locked in two contract faces, make it can not produce slip, angle the best that these two contract faces consist of is 60 °, can effectively guarantee the locking of cable wire 2.
As a kind of conversion of the present embodiment, droplet-shaped divide fiber tube 3 ' also can adopt other any one cable wire group 2 ' can be fixed on its bottom the sub-wire pipe belt replace.
Referring to Fig. 7, during manufacturing, first saddle body 5 is made moulding, penetrate droplet-shaped and divide fiber tube 3 ', again saddle body 5 inner chambers are watered and fill with C50 and behind close concrete 6, build into the Sarasota body.Cable wire 2 passes droplet-shaped at king-tower and divides fiber tube 3 ', is pressed on the Sarasota body, adopts the cable saddle of this kind structure to remove the horizontal component of cable wire 2 on bridge tower.Only has a power vertically downward at tower.Eliminated horizontal component to its destruction, also reduced construction costs simultaneously.The Sarasota requirement that this structure can solve arbitrary height according to the radius of the altitude conversion Sarasota saddle of dissimilar bridge.
