Abstract
The utility model discloses a kind of Novel water-drop type saddle system being applied to low-pylon cable-stayed bridge, comprise end plate, floor, right baffle-plate, right baffle plate, overhead gage, lower baffle plate, dividing plate, square opening is left in the middle of end plate, floor, end plate, right baffle-plate, right baffle plate is welded and fixed one, right baffle-plate and right baffle plate, overhead gage and lower baffle plate are to be parallel to each other and weld, dividing plate be distributed with water droplet hole and arrange corresponding with the hole of ground tackle, bottom, water droplet hole has 40 degree of angles, described dividing plate and right baffle-plate, right baffle plate, overhead gage, between lower baffle plate, space is full of high-strength mortar and is full of, cable body is fully contacted with duct.The utility model structure is simple, easily manufactured, effectively can not only prevent the slippage of cable body in saddle duct, and facilitates the later stage can carry out the single rope that changes to safeguard.
Description
Technical field
The utility model relates to cable stayed bridge prestressing technique field, specifically belongs to a kind of Novel water-drop type saddle being applied to low-pylon cable-stayed bridge.
Background technology
Sarasota is the turriform structure of cable stayed bridge supporting main rope.Long span suspension cable adopts concrete box shaped Sarasota to carry out anchoring drag-line mostly, and drag-line often adopts point symmetry anchorage style, and Sarasota carries out point symmetry anchor cable to use the traditional ground tackle be located on steel anchor beam.The stress state constructed under the tower anchor of this anchorage style is usually difficult to obtain reliable and lasting control, and Concrete-filled steel tube crack happens occasionally.
Saddle is a kind of indispensable important force transferring part in low-pylon cable-stayed bridge structure, current domestic conventional be circular point threaded pipe type saddle, when using this kind of saddle, cable body and duct are that circular arc contacts, rub less, cause under the effect of the live loads such as vehicle, cable body is slippage in sub-wire pore road easily, when using the devices such as antiskid key, anti-slip anchoring tube to prevent the slippage of cable body, so not only use very inconvenient, add construction costs, and strap can be changed to the later stage and carry out very large difficulty.
Utility model content
The purpose of this utility model is to provide a kind of Novel water-drop type saddle being applied to low-pylon cable-stayed bridge, reserve the method in droplet-shaped duct during by building high-strength mortar in saddle steel structure casing, the cable body existed during to efficiently solve and to use general point of threaded pipe type saddle easily in duct slippage and later stage change the problem of rope difficulty.
The technical solution of the utility model is as follows:
A kind of Novel water-drop type saddle system being applied to low-pylon cable-stayed bridge, comprise end plate, floor, right baffle-plate, right baffle plate, overhead gage, lower baffle plate, dividing plate, square opening is left in the middle of end plate, floor, end plate, right baffle-plate, right baffle plate is welded and fixed one, right baffle-plate and right baffle plate, overhead gage and lower baffle plate are to be parallel to each other and weld, dividing plate be distributed with water droplet hole and arrange corresponding with the hole of ground tackle, bottom, water droplet hole has 40 degree of angles, described dividing plate and right baffle-plate, right baffle plate, overhead gage, between lower baffle plate, space is full of high-strength mortar and is full of, cable body is fully contacted with duct.
The utility model water droplet nibs is 40 degree of angle designs, has larger chucking power to cable body.Saddle adopts droplet-shaped to divide fiber tube, plays an effect of good " stretch-draw is fastening, put lax ", meets Cable stress principle, the single replacing of suspension cable of being more convenient for; Saddle adopts high-strength grout formation drops to divide fiber tube profile; there is good opposing uneven Suo Li difference effect; by filling elastic polymeric material and make steel strand and mortar fully contact and the steel work of outside and high-strength mortar carrying out the media such as completely isolated steam, achieve multi-layer anticorrosion protection.
The utility model has the advantages that structure is simple, easily manufactured, effectively can not only prevent the slippage of cable body in saddle duct, and facilitate the later stage can carry out the single rope that changes to safeguard.
