Description
Technical field
The utility model is related to cable-stayed bridge, more particularly to a kind of cable-stayed bridge axial decompression steel anchor box.
Background technology
Cable-stayed bridge pylon is generally concrete hollow structure, and longitudinal both sides drag-line is anchored in bridge tower tower wall respectively.But tiltedly
Cable power is larger, can produce very big pulling force to bridge tower tower wall, it is sufficient to cause tower wall to be destroyed.In order to reduce suspension cable to tower wall
Pulling force, it is to avoid tower wall is destroyed, and steel anchor box is generally set between tower wall, and steel anchor box is fixed on bridge tower inwall, both sides drag-line point
Steel anchor box two ends are not anchored at, so that the pulling force of suspension cable is shared by steel anchor box and tower wall.
But due to steel anchor box tension cable horizontal component stretcher strain, can still apply greater level power to tower wall.Steel anchor box
Stress with tower wall is distributed by the deformation rigidity of respective horizontal distortion, in order to reduce tower wall stress, it is necessary to increase steel anchor box
Rigidity, so steel anchor box can use larger sectional dimension and thickness of slab, so but causes that steel anchor box stress is low, does not give full play to
Its material property, causes steel anchor box waste of material.On the other hand in order to further improve the drag of tower wall, typically also can be in tower wall
The interior prestressed cable that ring is set, to resist pulling force of the suspension cable to tower wall.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cable-stayed bridge axial decompression steel anchor box, makes suspension cable anchor
Gu the power of dividing equally of power is mainly undertaken by steel anchor box, steel anchor box stock utilization is improved, and effectively reduce anchor case to bridge tower tower wall
Extruding force, so as to advantageously reduce bridge construction cost.
The utility model solves the technical scheme that the technical problem used：
Cable-stayed bridge axial decompression steel anchor box of the present utility model, is arranged between the both sides tower wall of bridge tower, including steel anchor section
Section and the end steel plate for being welded on its transverse ends, it is characterized in that：It is fixedly installed between the end steel plate and tower wall paired
Corrugated sheet steel, the plate face of corrugated sheet steel makees vertically extending relative to the plate face of end steel and the surface of tower wall.
The beneficial effects of the utility model are, using corrugated sheet steel axial rigidity it is weak the characteristics of, by steel anchor box and tower wall
Horizontal distortion is kept apart, and the power of dividing equally of suspension cable anchor force is mainly undertaken by steel anchor box, effectively reduces level suffered by tower wall
Power, and allow steel anchor box to produce larger stretcher strain, the tensile property of steel anchor box steel is given full play to, effectively improve material
Utilization rate, material-saving；Effectively reduce extruding force of the anchor case to bridge tower tower wall so that cancel ring prestressed cable in tower wall
Possibility is set to, material is further saved, so as to advantageously reduce bridge construction cost.
Brief description of the drawings
This specification includes following six width accompanying drawing：
Fig. 1 is traditional steel anchor box structural representation.
Fig. 2 is the elevational schematic view of the utility model cable-stayed bridge axial decompression steel anchor box；
Fig. 3 is the floor map of the utility model cable-stayed bridge axial decompression steel anchor box；
Fig. 4 is the sectional view of the A-A along Fig. 2；
Fig. 5 is the sectional view of the B-B along Fig. 2；
Fig. 6 is the connection drawing of corrugated sheet steel in the utility model cable-stayed bridge axial decompression steel anchor box.
Parts, toponym and corresponding mark are shown in figure：Steel anchor sections 1, tower wall 2, suspension cable anchor plate 3,
Suspension cable by positioning steel tube 4, corrugated sheet steel 5, inner side flat segments 51, outside flat segments 52, ribbed stiffener 6, inner side ribbed stiffener 61,
Outside ribbed stiffener 62, WELDING STUDS connector 7, end steel plate 8, junction steel plate 9.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 1, traditional steel anchor box includes steel anchor sections and is welded on the end steel plate of its transverse ends, end in structure
WELDING STUDS connector is laid in the bottom surface of steel plate, and WELDING STUDS connector is embedded in tower wall concrete.Steel anchor box tension cable level point
Power stretcher strain, can apply greater level power to tower wall, and steel anchor box is firm by the deformation of respective horizontal distortion with the stress of tower wall
Degree distribution.In order to reduce tower wall stress, it is necessary to increase the rigidity of steel anchor box, thus steel anchor box can using larger sectional dimension and
Thickness of slab, so but causes that steel anchor box stress is low, does not give full play to its material property, causes steel anchor box waste of material.The opposing party
Face typically can also set the prestressed cable of ring, to resist suspension cable to further improve the drag of tower wall in tower wall
To the pulling force of tower wall.
Reference picture 2, Fig. 3 and Fig. 4, the utility model cable-stayed bridge axial decompression steel anchor box, are arranged at the both sides tower wall 2 of bridge tower
Between, including steel anchor sections 1 and the end steel plate 8 for being welded on its transverse ends.It is fixed between the end steel plate 8 and tower wall 2
Be arranged to corrugated sheet steel 5,5 plate face of corrugated sheet steel 5 erects relative to the plate face of end steel plate 8 and the surface of tower wall 2
To extension.Using the axial rigidity of corrugated sheet steel 5 it is weak the characteristics of, steel anchor box is kept apart with the horizontal distortion of tower wall, make suspension cable
The power of dividing equally of anchor force is mainly undertaken by steel anchor box, effectively reduces horizontal force suffered by tower wall, and it is larger to allow steel anchor box to produce
Stretcher strain, give full play to the tensile property of steel anchor box steel, effectively improve stock utilization, material-saving.Have simultaneously
Effect reduces anchor case to the extruding force of bridge tower tower wall so that cancels ring prestressed cable in tower wall is set to possibility, enters one
Step saves material, so as to advantageously reduce bridge construction cost.
Reference picture 5, the vertical two ends of the corrugated sheet steel 5 have inner side flat segments 51, outside flat segments 52 respectively.In pairs
Corrugated sheet steel 5 between, interval setting inner side ribbed stiffener 61, outside ribbed stiffener 62, inner side ribbed stiffener 61 and inner side flat segments 51,
End steel plate 8 is welded, and outside ribbed stiffener (62) is welded with outside flat segments 52, junction steel plate 9, to be prevented effectively from corrugated sheet steel 5
Two ends unstability and influence it with end steel plate 8, the switching performance of junction steel plate 9.Reference picture 2, the bottom surface cloth of the junction steel plate 9
If WELDING STUDS connector 7, WELDING STUDS connector 7 is embedded in the concrete of tower wall 2.
The above is some principles of the present utility model that explain through diagrams, and is not intended to be confined to the utility model
In shown and described concrete structure and the scope of application, therefore every corresponding modification for being possible to be utilized and equivalent,
Belong to the apllied the scope of the claims of the utility model.
