Abstract
The utility model discloses a composite material tube pile with inner ribs. The composite material tube pile comprises composite material winding tubes and concrete which is filled into the composite material winding tubes. The composite material winding tubes comprise composite material internal die circular tubes, the longitudinal ribs and fiber yarns. The longitudinal ribs are arranged on the inner walls of the composite material internal die circular tubes. The fiber yarns are wound on the outer walls of the composite material internal die circular tubes to form the composite material winding tubes. By the adoption of the composite material tube pile with the inner ribs, the tube pile and the pier stud concrete can be protected from corrosion of harmful substances, the compressive strength of the concrete is improved, the interface bonding strength of the composite material tubes and the concrete can be enhanced, the tube pile and a pier stud structure are durable, and the ductility of concrete pier studs is improved and enhanced.
Description
Technical field
The utility model relates to a kind of pile tube, be specifically related to a kind of Novel tubular pile that improves composite material outer tube and core concrete adhesive property, can be used for prefabricated tubular pile basis, the bridge pier column of the corrosive environment newly-built structures such as ocean, also can be used for reinforcing existing steel concrete and prestressed concrete pier stud.
Background technology
Steel concrete, prestressed reinforced concrete pipe pile or bored concrete pile foundation are one of civil engineering pile foundation forms commonly used, and existing bridge pier column also adopts steel concrete, prestressed reinforced concrete structures more simultaneously.Although the corrosion of concrete structure is compared slowly with steel work in marine environment, easily ignored by the people, in case occur, be difficult to repair process, reinforcing bar is corroded the generation expansion and causes concrete cracking, further accelerated corrosion, thus affect component strength and availability.
In recent years, composite material is high-strength with it, lightweight, the advantage such as corrosion-resistant, and beginning is applied in building and building engineering structure, and is subject to the extensive concern of engineering circles.Do permanent template take composite material as outer tube is double, the composite constraining concrete tubing string that concrete filled forms successfully is used for building pile foundation, Cable stayed Bridge Main Tower and speedway beam bridge bridge pier abroad.Under the axial pressure effect, core concrete is subject to the lateral restraint of composite material tube, is in triaxial stress state, has improved concrete intensity.Compare with concrete filled steel tube, composite constraining concrete tubing string good corrosion resistance, the deadweight lighter.Because composite material and the concrete temperature coefficient of expansion differ larger, especially be subjected to curved state, interface peel easily occurs between bi-material, stress can't transmit.If can improve composite material tube and concrete interface binding intensity, can further improve ultimate bearing capacity and the application life of composite constraining performance of concrete column confined.
Have at present the molded through pultrusion of composite material band to indulge ribbed pipe abroad, but pultrude process can only be produced the uniform section framework, pipe that can't the forming strip cross rib.Rib can only be larger for interior caliber and stick with paste in length and breadth at the inboard secondary hand of in type tube wall, and enough manually-operated spaces are arranged, and complicated operation, and the rib that secondary is pasted easily comes off.

As preferably, described vertical rib is vertical, the cross rib horizontal arrangement, and perhaps cross rib is in tilted layout, and horizontal sextant angle is 15 °～45 °.
As preferably, described cross rib spacing is 10cm～20cm, and width is not less than 3cm, highly is not less than 3mm.
As preferably, the material of described composite material internal mold pipe be single, in length and breadth to fiber than 1:1, the carbon fiber of 1:2 or 1:4, glass fiber, basalt fibre or aryl fiber cloth, or different cloth is alternately laid; Resin used is unsaturated polyphenyl resin, polyethylene or epoxy resin.
As preferably, on described composite material internal mold circular tube external wall, unidirectional or two-way winding at a certain angle forms the Filament Wound Composite pipe through the fibre that resin infiltrates.
As preferably, the built-in steel pipe of described Filament Wound Composite pipe forms composite material-concrete-steel pipe sandwich pile tube.
As preferably, the built-in shaped steel of described Filament Wound Composite pipe forms composite material-steel reinforced concrete pile tube.
Beneficial effect: (1) the utility model has solved existing composite material tube and concrete interface adhesion problem, adopts the industrialization process moulding, forms the reinforced tube of longitudinal and transverse rib and tube wall one, and structural integrity is good, and internal-rib is not easy to come off;
(2) internal-rib flexible design is all easily realized according to the longitudinal and transverse rib that concrete force request is arranged;
(3) composite material tube useful as concrete with ribbing or the prestressed concrete permanent template of building, the layer of putting more energy into has increased composite material and concrete adhesion strength;
(4) round steel pipe or shaped steel be can place in composite material with ribbing, composite material with ribbing-steel tube-concrete pile tube or composite material with ribbing-steel reinforced concrete pile tube formed;
(5) composite material tube tensile strength with ribbing high, from heavy and light, good corrosion resistance, humidity, can protect concrete and steel to avoid the erosion of corrosive deposit, improve the application life of structure, also can be used for the reinforcing of old pier stud;
(6) composite material tube with ribbing can obviously be improved the ductility of performance of concrete column confined, because composite material all is in elastic state before destruction always, especially fiber can not produce permanent set and accumulation destruction under the course under cyclic loading of earthquake, and the pier stud strength degradation is few;
