Abstract
The utility model discloses an anchoring connecting structure for nodes of a composite truss girder cable-stayed bridge, which is characterized by comprising whole node plates, wherein a steel web member is welded with the whole node plates; the whole node plates are connected with a steel chord member; the steel chord member and the whole node plates are connected with a prestressed concrete chord member through shear nails; and a stay cable is anchored to the prestressed concrete chord member. According to the preferable embodiment of the utility model, a stay cable duct is arranged outside the stay cable, and stiffening plates are arranged on two sides of the stay cable duct and welded with the whole node plates; the stay cable duct penetrates through a web of the steel web member and a horizontal node plate, and is welded with the steel web member and the horizontal node plate; a bracing cable anchor block is arranged on the prestressed concrete chord member, and the stay cable is anchored onto the bracing cable anchor block through the stay cable duct; and welding stud connecting pieces are arranged on inner sides and outer sides of the whole node plates and are connected with the prestressed concrete chord member. The anchoring structure is simple, the force transmission is clear, and the construction is convenient.
Description
Technical field
The utility model belongs to technical field of bridge engineering, relate to the steel web member with the composite truss girder stayed-cable bridge joint anchorage syndeton of shaped steel.
Background technology
Composite truss beam bridge cable stayed bridge is in the stressed more complicated in suspension cable anchorage node place, the load that node is passed over by steel web member, string wire bar, suspension cable namely will, and the Load Transfer that also needs simultaneously to bear is to the prestressed concrete chord member, and is stressed very complicated.For this reason, research and design goes out the Types of nodes of a kind of reasonable stress, durable in use, easy construction, and tool is of great significance.
Summary of the invention
The purpose of this utility model is to provide a kind of composite truss girder stayed-cable bridge joint anchorage syndeton, the power transmission that can solve each main stressed member, and guarantee that Cable power can reasonably be delivered on string wire bar, prestressed concrete chord member and the steel web member.
To achieve these goals, the technical solution of the utility model is as follows: a kind of composite truss girder stayed-cable bridge joint anchorage syndeton, it is characterized in that described anchor connection structure comprises the integral node plate, steel web member and the welding of this integral node plate, this integral node plate is connected with the string wire bar, string wire bar, integral node plate are connected with the prestressed concrete chord member, and suspension cable is anchored in the prestressed concrete chord member.According to a preferred embodiment of the invention, suspension cable is provided with the inclined cable conduit outward, and inclined cable conduit both sides arrange stiffener and the welding of integral node plate.The anchor connection structure comprises two blocks of integral node plates that be arranged in parallel, wherein steel web member web vertically is arranged between two blocks of integral node plates and with described integral node plate and welds, horizontal node plate level is arranged between two blocks of integral node plates and with described integral node plate and welds, the inclined cable conduit passes described steel web member web and horizontal gusset plate, inclined cable conduit and steel web member web and the welding of horizontal gusset plate.The prestressed concrete chord member is provided with the drag-line anchor block, and suspension cable is anchored on the drag-line anchor block by the inclined cable conduit.The inside and outside both sides of integral node plate all arrange weldering nail connector and are connected with the prestressed concrete chord member.
This structure can solve preferably chord member, web member, crossbeam and beam rope anchoring structure and concentrate the problem that crosses, Cable power is transmitted respectively by gusset plate and concrete chord member anchor block, reduced the stress concentration phenomenon, has preferably stress performance, increase structural safety degree more than needed, also reduced the difficulty of processing and manufacturing simultaneously.
