Abstract
The utility model relates to a kind of new type FRP profile-concrete combination beams, including FRP profile, ultra-high performance concrete and normal concrete are equipped at the top of the FRP profile, ultra-high performance concrete is equipped between FRP profile and normal concrete, it is in concave at the top of the FRP profile, ultra-high performance concrete lower end is in convex, and FRP profile top and ultra-high performance concrete lower end are corresponding, passes through shearing key connection between FRP profile and ultra-high performance concrete.The utility model has the advantages that structure is simple, self weight is small, bearing capacity is high.
Description
Technical field
The utility model belongs to construction engineering technical field, and in particular to a kind of new type FRP profile-concrete combination beam.
Background technique
In recent years, high resistance to due to the great demand that the implementation of China's "Oceanic" strategy and infrastructure durability are urgently promoted
The application scale of long property bridge structure is very huge.FRP profile is because having the features such as high-strength light, corrosion-resistant, nonmagnetic, gradually
It applies in building and bridge structure.Since that there are costs is excessively high, elasticity modulus is lower and shear strength for pure FRP profile structure
The disadvantages of far below its tensile strength, more scholars begin one's study FRP profile-concrete combined structure.FRP profile-concrete
Composite structure can give full play to FRP profile and the respective mechanical property advantage of concrete.
When FRP profile-concrete combined structure is used for longspan structure formula, in order to meet force request, FRP type at this time
Material-concrete combined structure sectional dimension is bigger than normal, and dead load is overweight.In face of Qiongzhou Strait, Bohai Sea Gulf and western mountainous areas grand canyon
The overlength such as paddy, super large cross over construction demand, need to research and develop the strong engineering material of lightweight, superelevation, with improve bridge span ability,
Support the innovation of super-span structural system.FRP profile is a kind of high-strength light, corrosion-resistant material, but we also need using
High performance material removes the normal concrete in substitution FRP profile-concrete combined structure, improves structure tension performance, mitigates knot
Structure self weight.
Utility model content
A kind of new type FRP profile-Combined concrete is provided the purpose of the utility model is to overcome the deficiencies in the prior art
Beam.
The technical solution of the utility model is as follows:
A kind of new type FRP profile-concrete combination beam, including FRP profile, the FRP profile top are equipped with very-high performance
Concrete and normal concrete are equipped with ultra-high performance concrete, the FRP profile top between FRP profile and normal concrete
In concave, ultra-high performance concrete lower end is in convex, and FRP profile top and ultra-high performance concrete lower end are corresponding, FRP profile
Pass through shearing key connection between ultra-high performance concrete.
Further, the FRP profile is in " work " type.
Further, the shear connector is in " work " type, T-shape or hexagon.
Further, the shear connector is uniformly arranged on FRP profile dome top surface, the quantity at least two of shear connector.
Further, it is equipped with perforation muscle at the top of the FRP profile at concave between inner wall, the perforation muscle runs through very-high performance
The high spot of concrete lower end convex.
Further, the ultra-high performance concrete is UHPC.
Compared with prior art, the utility model has the beneficial effects that
It 1, is in concave at the top of the FRP profile, concrete lower end is in convex, and FRP profile top and concrete lower end are opposite
It answers, FRP profile and concrete surface product are bigger, and tongue and groove, which matches, prevents concrete from moving left and right, FRP profile and concrete
It connects stronger；
2, it is keyed between FRP profile and ultra-high performance concrete by shearing, inner wall at concave at the top of the FRP profile
Between be equipped with perforation muscle, it is described perforation muscle run through ultra-high performance concrete lower end convex high spot, pass through shear connector and perforation
Muscle connects FRP profile with concrete stronger；
3, FRP profile keeps beam more stable in structure as " work " type.
In short, the utility model has the advantages that structure is simple, self weight is small, bearing capacity is high.
Detailed description of the invention
Fig. 1 the utility model section figure.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of 2 combination beam of new type FRP profile 1- concrete, including FRP profile 1, the FRP profile 1 push up
Portion is equipped with ultra-high performance concrete 2 and normal concrete 5, and the ultra-high performance concrete 2 is UHPC, and FRP profile 1 is mixed with common
Ultra-high performance concrete 2 is equipped between solidifying soil 5, the FRP profile 1 is in " work " type, makes 2 combination beam of FRP profile 1- concrete more
Steadily, more stable, it is in concave at the top of the FRP profile 1,2 lower end of concrete is in convex, under 1 top of FRP profile and concrete 2
Hold it is corresponding, in this way connection keep FRP profile 1 and 2 contact area of concrete bigger, tongue and groove, which matches, prevents concrete 2 or so
Movement, FRP profile 1 and concrete 2 connect stronger.
It is connected between FRP profile 1 and ultra-high performance concrete 2 by shear connector 3, the shear connector 3 is in " work " type, " T "
Type or hexagon are equipped with perforation muscle 4 at the 1 top concave of FRP profile between inner wall, the perforation muscle 4 is through very-high performance
The high spot of 2 lower end convex of concrete connects FRP profile 1 and concrete 2 stronger by shear connector 3 and perforation muscle 4；
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
