Toppling of bridge main beam, it is ensured that the normal of bridge uses and the safety of space under bridge.
For reaching above-mentioned purpose, this utility model is implemented according to techniques below scheme:
A kind of Single column pier bridge Overthrow preventing device, is arranged on bridge main beam and Single column pier, described bridge main beam and only post
Pier is connected by anchor and strong guy cable, and described anchor includes pre-buried strength drag hook or is connected chemically crab-bolt, location
Plate, high-strength nut and tension seat, described pre-buried strength drag hook or be connected chemically one end of crab-bolt and be arranged on bridge main beam and/or solely
In stub, pre-buried strength drag hook or be connected chemically the crab-bolt other end by location-plate and high-strength nut affixed with tension seat, described
Connected by strong guy cable between the tension seat of bridge main beam and Single column pier the same side, outside described strong guy cable includes from outside to inside
Layer protective layer, internal layer protective layer and steel wire, external protection and inner protective layer primarily serve the effect from corrosion of the protection steel wire.
Further, the hook end of described pre-buried strength drag hook is embedded in bridge main beam and/or Single column pier, and pre-buried strength is drawn
The neck of hook end of hook is provided with external screw thread, and the neck of hook end high-strength nut of described pre-buried strength drag hook is fixing with one end of tension seat even
Connecing, the other end of described tension seat is provided with the through hole for connecting strong guy cable.
Concrete, described in be connected chemically one end of crab-bolt and be embedded in bridge main beam and/or Single column pier, be connected chemically crab-bolt
The other end be provided with external screw thread, described in be connected chemically that one end of one end high-strength nut of crab-bolt and tension seat is fixing to be connected, institute
The other end stating tension seat is provided with the through hole for connecting strong guy cable.
Work process of the present utility model and operation principle be:
Bridge main beam is as the superstructure of bridge, and under Under Eccentric Loading, it may occur however that torsional displacement, this is for bridge
The normal use with the safety under bridge of beam is all disadvantageous.By a secondary strong guy cable, bridge main beam and Single column pier are transversely added
With constraint, girder can be prevented effectively from and topple.
Compared with prior art, the beneficial effects of the utility model are:
1, bridge main beam and Single column pier lateral displacement are used restraint by this utility model by strong guy cable and anchoring part, can
Topple being prevented effectively from bridge main beam, it is ensured that under the safe handling of bridge and bridge, traffic safety is unimpeded;
2, this utility model range is wide, for the version not requirement of bridge main beam and Single column pier, therefore, and should
Utility model is applicable to various Single column pier bridge structure, can effectively solve Single column pier bridge main beam and topple problem;
3, anchor is simple and effective, is effectively protected the service life that can increase this device.
