Abstract
The utility model belongs to the manufacturing technical field of the bridge component, in particular relates to a steel anchor beam for connecting the cable tower ends of a cable-stayed bridge, which comprises steel beams and anchoring heads for fixedly connecting with one end of the cable of the cable-stayed bridge. The steel beam presents a box type and is formed by welding steel plates; the four anchoring heads are symmetrically arranged at the both ends of the box-shaped steel beam. The steel anchor beam of the utility model has the advantages that the structure design is reasonable, the stress is definite, the use amount of steel is small, the cost is low, and the hoisting weight is light, and the steel anchor beam can be applied to the cable-stayed bridge with the parallel cable surface and the cable-stayed bridge with the spatial cable surface.
Description
Technical field
The utility model belongs to bridge member manufacturing technology field, particularly a kind of steel anchor beam of oblique tensile tower client link of cable stayed bridge.
Background technology
The suspension cable of cable stayed bridge and the bind mode of king-post have three kinds usually: prestress anchoraging, steel anchor box anchoring and the anchoring of steel anchor beam.Wherein, stride the footpath cable stayed bridge for a short time and adopt the prestress anchoraging mode more, but its loss of prestress is big.The long span stayed-cable bridge Sarasota is higher, and work high above the ground influences construction quality, and concrete is easy to crack, to the tower end anchorage style employing steel anchor box anchoring of long span stayed-cable bridge.Steel anchor box can be made in batches, and can ensure the quality of products, speed of application is fast, stressed reliable.But no matter be built-in or the steel anchor box of external, owing to there are two kinds of different materials of steel and concrete, both actings in conjunction cause concrete towers wall cracking inevitably, influence the durability and the stability of tower column structure, and the steel anchor box steel using amount is big, cost is high, during installation construction equipment is required height, need the large-scale hanging device of configuration, especially in marine environment, higher to Sarasota durability of structures and stability requirement, so the application of steel anchor box has limitation.Extensively adopt the anchoring of steel anchor beam at present, it has plurality of advantages.But in the present steel anchor beam anchor structure, owing to exist horizontal out-of-balance force, this mode to be only applicable to parallel rope face cable stayed bridge, can not be applicable to Spatial Cable face cable stayed bridge, its scope of application is subjected to greatly limiting; In addition, though the horizontal out-of-balance force of king-post anchorage zone is little, also can the king-post of parallel rope face cable stayed bridge be had a negative impact.So, be necessary to design a kind of energy and be suitable for parallel and Spatial Cable face cable stayed bridge, both economy and durability, the steel anchor beam structure of convenient construction again.
Summary of the invention
The utility model discloses the steel anchor beam of the oblique tensile tower client link of a kind of reasonable in design, stressed clear and definite, rolled steel dosage is few, cost is low, hoisting weight is light cable stayed bridge, it both can be used for parallel rope face cable stayed bridge, also can be used for Spatial Cable face cable stayed bridge.
For solving the problems of the technologies described above technical solution adopted in the utility model: the steel anchor beam of the oblique tensile tower client link of cable stayed bridge, comprise the anchorage head of girder steel and fixedly connected suspension cable one end, girder steel is box-shaped, is welded by steel plate; Four suspension cable anchorage heads are symmetrically set in the two ends of box steel beam.
The steel anchor beam of the oblique tensile tower client link of described cable stayed bridge, anchorage head is welded by anchor slab and gripper shoe, and anchor slab and gripper shoe are all welded with girder steel; Anchor slab is vertical with suspension cable, and gripper shoe is parallel with suspension cable.
The steel anchor beam of the oblique tensile tower client link of described cable stayed bridge, box steel beam inside is welded with stiffener.
The steel anchor beam is the individual member in the stayed bridge pylon cable, is supported on the vertical bracket of the hollow king-post tower of cable stayed bridge wall, and respectively there are two anchorage heads that connect suspension cable at its two ends, and anchorage head is used for fixing the upper end of suspension cable.The anchorage head that steel anchor beam of the present utility model welds four symmetries altogether is used to connect suspension cable, and the inside and outside equilibrium level component of the face of every pair of suspension cable is born by the steel anchor beam, and the outer a small amount of uneven horizontal component of face is born by king-post; The vertical force component of suspension cable passes to the tower wall by bracket and is born by king-post.It is both applicable to parallel rope face cable stayed bridge, also applicable to Spatial Cable face cable stayed bridge, also in the construction applicable to other bridge.
Description of drawings
Fig. 1 is the structural representation of the utility model steel anchor beam.
Fig. 2 is the structure vertical view of the utility model steel anchor beam.
In the diagram, 1-girder steel, 2-upper cover plate, 3-lower cover, 4-diaphragm, 5-anchorage head, 6-anchor slab, 7-gripper shoe, 8-web, 9-side plate, 10-stiffener.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, 2, the steel anchor beam of the oblique tensile tower client link of cable stayed bridge is made of the anchorage head 5 that box steel beam 1 and four are used to connect suspension cable.Box steel beam 1 is welded by upper cover plate 2, biside plate 9 and lower cover 3, and the middle intersegmental part of box steel beam 1 is five diaphragms 4 of welding evenly, and inner two ends is respectively welded five stiffeners 10, and diaphragm 4 and stiffener 10 have been strengthened the intensity of box steel beam 1.Two anchorage heads 5 are respectively welded at the two ends of box steel beam 1, and anchorage head 5 is symmetrically distributed, and anchorage head 5 is welded by anchor slab 6 and gripper shoe 7, and anchor slab 6, gripper shoe 7 are all welded with girder steel 1.The upper end of suspension cable penetrates anchorage head 5 and is connected to a fixed, and suspension cable is vertical with anchor slab 6, and is parallel with gripper shoe 7.Four anchorage head 5 symmetric arrangement can balance the equilibrium level component of the inside and outside horizontal direction of face, make the king-post of parallel rope face cable stayed bridge more stable, also make the steel anchor beam go for Spatial Cable face cable stayed bridge, have enlarged its scope of application.
Compared with prior art, the steel anchor beam of the oblique tensile tower client link of the utility model cable-stayed bridge has knot Structure rationally, stress balance, rolled steel dosage is few, cost is low, hoisting weight is light advantage.
The steel anchor beam of the oblique tensile tower client link of the utility model cable-stayed bridge also can in other bridge construction To use.
