Abstract
The concrete beam that FRP grid is reinforced, comprises concrete beam, has groove at the tension side of concrete beam, be provided with FRP grid and adhesive layer in groove; FRP grid is clipped in adhesive layer internal fixtion in groove, has following advantage: 1, tensile strength is high compared with the concrete beam that FRP grid reinforced concrete beam and traditional approach are reinforced.2, excellent decay resistance.3, density is little.4, coefficient of thermal expansion is close with concrete.5, lattice structure and cementing agent can produce good compatibility.
Description
Technical field
The utility model relates to the concrete beam that a kind of FRP grid is reinforced, and belongs to concrete structure reinforcement field, is specifically applicable to the concrete beam needing in building structure to carry out reinforcing and repairing.
Background technology
Concrete structure is applied more in Practical Project, the advantages such as supporting capacity is high, good integrity, rigidity are large, fire resistance is good that it has.But, building structure in-service, due under endo acting in conjunction, its bearing capacity or using function are declined and cannot meet normal instructions for use, these building structure inevitably will in the face of reinforcing problem, and builing industry tradition reinforcement means mainly contains increasing section reinforcing method, reinforced with external steel encased, prestressing, reinforcement by sticking of sheets and change stress system reinforcing method etc.Tradition reinforcement means is adopted in a large number in engineering practice, but in some cases, some limitation existing for these methods self, makes them can not meet the demand of durability and aesthetic, or be subject to the restriction of execution conditions and cannot implement.
Summary of the invention
Utility model object: the utility model provides the concrete beam that a kind of FRP grid is reinforced, its objective is the problem that consolidation effect existing for solution mode is in the past undesirable.
technical scheme: the utility model is achieved through the following technical solutions:
The concrete beam that FRP grid is reinforced, comprises concrete beam, it is characterized in that: have groove at the tension side of concrete beam, be provided with FRP grid and adhesive layer in groove; FRP grid is clipped in adhesive layer internal fixtion in groove.
Described FRP grid is fenestral fabric, comprises CFRP grid, GFRP grid or BFRP grid; Described adhesive layer is modified epoxy class bicomponent structural glue-line.
advantage and effect:
The concrete beam that the utility model provides a kind of FRP grid to reinforce, has following advantage compared with the concrete beam that FRP grid reinforced concrete beam and traditional approach are reinforced:
1, tensile strength is high, is more than 3 times of reinforced steel bar strength under equal conditions.
2, excellent decay resistance.
Beam after reinforcing divides cracking by the curved colloid part that there will be, and produce crack, now if wet environment, steam can enter crack, the corrosion of ordinary steel influential point of tendons, and FRP material can not be corroded.
3, density is little, is only 1/4 of plain bars, compared with traditional reinforcement, effectively reduces deadweight.
4, coefficient of thermal expansion is close with concrete, can not produce excessive thermal stresses.
5, lattice structure and cementing agent can produce good compatibility, and bond effect is excellent.
accompanying drawing illustrates:
Fig. 1 uses novel schematic diagram for this;
Fig. 2 is stereogram;
Fig. 3 is the structure chart of FRP grid.
In figure: 1---concrete beam;
2---FRP grid;
3---cementing agent; .
detailed description of the invention:below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, the concrete beam that the utility model provides a kind of FRP grid to reinforce, comprises concrete beam 1, has groove at the tension side of concrete beam 1, be provided with FRP grid 2 and adhesive layer 3 in groove; FRP grid 2 is clipped in adhesive layer 3 internal fixtion in groove.
Described FRP grid 2 is fenestral fabric, comprises CFRP grid, GFRP grid or BFRP grid; Described adhesive layer 3 is modified epoxy class bicomponent structural glue-line.
Below in conjunction with specific embodiment, the utility model is described in detail.
A concrete beam for FRP grid reinforcing, comprising: concrete beam 1, FRP grid 2, adhesive layer (3) as described in Figure.
Above-mentioned adhesive layer 3 is two parts, Part I is applied between concrete beam tension side fluting place and FRP grid 2, make FRP grid 2 build-in in groove, smear Part II adhesive layer 3 more subsequently, FRP grid 2 is wrapped up completely and makes the surfacing of concrete beam tension side simultaneously.
The purpose of this utility model is promoted in China's field of reinforcement in order to FRP grid reinforced concrete beam technology, provide a kind of component being conducive to reinforced concrete beam, can either reinforce concrete structure, make it meet using function, simultaneously again can convenient construction, decreasing pollution.
