Abstract
The utility model discloses a single-end tension P anchor reinforcing steel bar, which comprises a fixed anchor plate, an extrusion sleeve, a steel strand, a corrugated pipe, a restraining ring and a spiral rib; one end of the steel strand sequentially penetrates through the fixed anchor plate and the extrusion sleeve, and the other end of the steel strand sequentially penetrates through the restraining ring and the corrugated pipe; the bellows is located to the spiral muscle cover, the reinforcing bar net piece still wears to be equipped with on the steel strand wires, the reinforcing bar net piece is located between confinement ring and the fixed anchor board, the beneficial effects of the utility model are that: single-ended stretch-draw P anchor reinforcing bar sets up the reinforcing bar net piece through alternating in traditional P anchor fixed end steel strand wires position, and the effectual tensile stress of having solved has guaranteed single-ended stretch-draw quality for harm such as the drawing crack that steel strand wires concrete brought.
Description
Technical Field
The utility model belongs to bridge engineering construction field, concretely relates to single-ended stretch-draw P anchor reinforcing bar.
Background
The P anchor is also called a flat anchor, is a technology applied to single-end tensioning, is commonly used in an arch bridge and is used for connecting an arch support and the first section of an arch rib to ensure the tight connection degree of the arch support and the first section of the arch rib. The general P anchor comprises a corrugated pipe, a restraining ring, a grout outlet, a spiral rib, a steel strand, a fixed anchor plate, an extrusion sleeve and the like, and is characterized in that no reinforcing device is arranged near the steel strand, and quality accidents are easily caused by the fact that nearby concrete is pulled to crack in the tensioning process.
SUMMERY OF THE UTILITY MODEL
The application mainly aims to provide a single-end tension P anchor reinforcing steel bar capable of effectively solving the problems of tension stress, tension crack and other damages to steel strand concrete.
In order to achieve the above object, the present invention provides the following technical solutions:
a single-end tension P-anchor reinforcing steel bar comprises a fixed anchor plate, an extrusion sleeve, a steel strand, a corrugated pipe, a restraining ring and a spiral rib; one end of the steel strand sequentially penetrates through the fixed anchor plate and the extrusion sleeve, and the other end of the steel strand sequentially penetrates through the restraining ring and the corrugated pipe; the spiral rib is sleeved on the corrugated pipe; and a reinforcing steel bar net piece is arranged on the steel strand in a penetrating manner and is positioned between the restraint ring and the fixed anchor plate.
As a preferred embodiment, the number of the steel mesh sheets is 3-6, and the 3-6 steel mesh sheets are uniformly distributed between the restraining ring and the fixed anchor plate.
As a preferred embodiment, when the steel strand passes through the steel mesh, the steel strand coincides with the central axis of the steel mesh.
As a preferred embodiment, the area of the reinforcing mesh is 0.25m2。
As a preferred embodiment, the distance between two adjacent reinforcing mesh sheets is 8-12 cm.
The single-end tension P-anchor reinforcing steel bar is characterized in that the reinforcing mesh is composed of reinforcing steel bars with the diameter of 10-14 mm, and preferably, the reinforcing mesh is composed of reinforcing steel bars with the diameter of 12 mm.
Compared with the prior art, the beneficial effects of the utility model are that: single-ended stretch-draw P anchor reinforcing bar sets up the reinforcing bar net piece through alternating in traditional P anchor fixed end steel strand wires position, and the effectual tensile stress of having solved has guaranteed single-ended stretch-draw quality for harm such as the drawing crack that steel strand wires concrete brought.
