Think material, the comprehensive performance of Cable Structure can be improved.But CFRP material be it is orthotropic, horizontal mechanical performance is much
Lower than vertical mixing coefficient, this brings obstruction to its application.CFRP drag-line will receive cross at the node in string branch structure
Effect to load, easily occurs shearing and bending damage, therefore the rational structure of node becomes CFRP drag-line to play its excellent
The key of good vertical mixing coefficient.The utility model design CFRP drag-line strut node sufficiently research CFRP drag-line shearing,
On the basis of bending performance, by five truckles of the lockhole axle center of node on certain circular arc, bypass drag-line at node
The uniform curve transition of pulley not only can be reduced prestressing frictional loss, but also can prevent shearing and bending damage.
Utility model content
For the prior art, in order to enable CFRP material is safe and reliable to be used in string branch structure, the utility model
A kind of CFRP drag-line strut node for string branch structure is devised, which is arranged in same circular arc line by a row axle center
On spill pulley, realize CFRP drag-line uniform curve transition at node, prevent shearing and bending damage, reduce prestressing force rub
It wears mistake.
In order to solve the problems, such as that damage failure easily occurs under lateral load effect for CFRP drag-line existing in the prior art,
A kind of technical solution of CFRP drag-line strut node for string branch structure provided by the utility model is that this is used for string branch structure
CFRP drag-line strut node, including column bracket, one end of the lateral wall of the column bracket is equipped with an otic placode, and the otic placode is for connecting
Suspension cable is connect, the other end of the lateral wall of the column bracket is equipped with the support baseboard of CFRP drag-line, and the support baseboard is close to column
The side of support is equipped with backboard, and the backboard is equipped with the cover board that can cover the support baseboard, the cover board and the support
Bottom plate is parallel, between the support baseboard and the cover board be equipped with row's spill pulley, the axis of the spill pulley with it is described
Support baseboard is vertical, and the both ends of the spill pulley are equipped with roller bearing, and the roller bearing is inlaid on the support baseboard and cover board,
On a circular arc line, the radius R and central angle θ of the circular arc line are selected according to the internal force of CFRP Cable in the axle center of all roller bearings
It takes, the distance between the spill pulley and backboard are greater than the diameter of CFRP drag-line.
Further, the utility model be used for string branch structure CFRP drag-line strut node, wherein the cover board with it is described
It is connected by screw bolts between backboard.
Compared with prior art, the utility model has the beneficial effects that
The utility model proposes a kind of CFRP drag-line strut node for string branch structure can both ensure CFRP drag-line
Trouble free service is without being sheared and being bent damage in string branch structure, and CFRP drag-line can be promoted in other tensioning type knots
It is applied in structure.To realize that CFRP drag-line is safely and reliably applied in string branch structure.The node can be applied to other
In Cable Structure, it can further promote application of the CFRP drag-line in Cable Structure.
