Abstract
The utility model relates to a reinforced anti-fatigue-damage anchor tube type anchor pulling plate structure; the method is characterized in that: the device comprises an anchor backing plate, an anchor pull pipe, an upper anchor pull plate, a pressure bearing plate, an upper circular plate, an upper sleeve, reinforcing stiffening ribs at two sides of an anchor pull plate notch, an anchor pull pipe stiffening plate, an anchor pull plate upper arc mouth stiffening plate and a lower anchor pull plate; the anchor pipe unit is manufactured in a factory by an anchor backing plate, an anchor pipe, an upper anchor plate, a bearing plate, an upper circular plate, an upper sleeve, an anchor pipe stiffening plate and an anchor plate upper arc opening stiffening plate, the lower anchor plate and a steel box girder web plate are integrally blanked, the upper anchor plate and the lower anchor plate are butted on site, and finally reinforcing stiffening ribs on two sides of an anchor plate slot are welded to complete installation. The anchor plate structure aims to solve the problems of stress concentration and fatigue at the welding seam between the anchor plate and the bridge deck slab, the welding seam between the anchor plate and the anchor pipe and the upper round angle of the anchor plate hole.
Description
Technical Field
The utility model relates to a bridge construction field specifically is a strenghthened type antifatigue destruction anchor cast anchor arm-tie plate structure.
Background
The cable-stayed bridge is one of main bridge types of a large-span bridge, is applied more and more widely, mainly comprises a cable tower, a main beam, a stay cable and the like, and a cable-beam anchoring structure for connecting the main beam and the stay cable is a key structure of the cable-beam anchoring structure. The anchor plate is one of the main types of cable-stayed bridge cable-beam anchoring structures, has definite force transmission mode and is often the first choice of the cable-beam anchoring structure. However, the existing shrinkage anchoring structure has the problems of stress concentration and fatigue at the welding seam between the anchor plate and the bridge deck slab, the welding seam between the anchor plate and the anchor pipe and the upper round corner of the anchor plate opening.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a strenghthened type antifatigue destruction anchor cast anchor arm-tie plate structure.
In order to achieve the above object, the present invention is realized as follows:
a reinforced anti-fatigue-damage anchor tube type anchor plate structure comprises an anchor backing plate (1), an anchor pipe (2), an upper anchor plate (3), a pressure bearing plate (4), an upper circular plate (5), an upper sleeve (6), reinforcing stiffening ribs (7) at two sides of an anchor plate slot, an anchor pipe stiffening plate (8), an anchor plate upper arc mouth stiffening plate (9) and a lower anchor plate (10); the steel box girder construction method comprises the following steps of manufacturing an anchor pipe unit in a factory by using an anchor backing plate (1), an anchor pipe (2), an upper anchor plate (3), a pressure bearing plate (4), an upper circular plate (5), an upper sleeve (6), an anchor pipe stiffening plate (8) and an anchor plate upper arc opening stiffening plate (9), blanking a lower anchor plate and a steel box girder web plate integrally, butt-jointing the upper anchor plate and the lower anchor plate on site, and finally welding reinforcing stiffening ribs (7) on two sides of an anchor plate slot to complete installation.
Compared with the traditional structure, the structure has the following characteristics:
1. compared with the traditional anchor pipe type anchor plate structure, the bearing plate and the reinforcing stiffening ribs on the two sides of the anchor plate are additionally arranged, so that the rigidity of the section is enhanced, the force transmission section is increased, and the stress performance is better.
2. The anchor plate splicing welding seam, the panel welding seam and the web welding seam are staggered, overlapping welding seams are avoided, stress concentration is reduced, and the possibility of fatigue damage is reduced.
3. Stress concentration of an internal corner formed by opening holes of the anchor pipe type anchor pulling plate is greatly reduced by arranging a large fillet and arranging an arc reinforcing plate.

Fig. 2 is a structural schematic diagram of the anchor plate structure.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1 and 2, a reinforced fatigue failure-resistant anchor tube type anchor plate structure comprises an anchor backing plate 1, an anchor pipe 2, an upper anchor plate 3, a pressure-bearing plate 4, an upper circular plate 5, an upper sleeve 6, reinforcing stiffening ribs 7 at two sides of an anchor plate slot, an anchor pipe stiffening plate 8, an anchor plate upper arc mouth stiffening plate 9 and a lower anchor plate 10; the steel box girder construction method comprises the steps of manufacturing an anchor pipe unit by a factory through an anchor backing plate 1, an anchor pipe 2, an upper anchor plate 3, a bearing plate 4, an upper circular plate 5, an upper sleeve 6, an anchor pipe stiffening plate 8 and an anchor plate upper arc mouth stiffening plate 9, blanking a lower anchor plate and a steel box girder web plate integrally, butt-jointing the upper anchor plate and the lower anchor plate on site, and finally welding reinforcing stiffening ribs 7 on two sides of an anchor plate slot to complete installation.
Compared with the traditional structure, the structure has the following characteristics:
1. compared with the traditional anchor pipe type anchor plate structure, the bearing plate and the reinforcing stiffening ribs on the two sides of the anchor plate are additionally arranged, so that the rigidity of the section is enhanced, the force transmission section is increased, and the stress performance is better.
2. The anchor plate splicing welding seam, the panel welding seam and the web welding seam are staggered, overlapping welding seams are avoided, stress concentration is reduced, and the possibility of fatigue damage is reduced.
3. Stress concentration of an internal corner formed by opening holes of the anchor pipe type anchor pulling plate is greatly reduced by arranging a large fillet and arranging an arc reinforcing plate.
