Description
Technical field
The utility model relates to Reinforcement Technology of Concrete Structure field, the fiber cloth reinforced structure of especially a kind of power.
Background technology
In construction industry development process, maintenance and reinforcement for various building makes necessary construction sequence, and simple concrete strengthening technology still needs to improve constantly with perfect, intensity is high owing to having for carbon cloth, quality is light, durability and the advantage such as good corrosion resistance, easy construction, be widely used in civil engineering field of reinforcement, particularly to the reinforcing of old bridge, Old building.But, adopt the concrete flexural member of direct affixing carbon fabric to there is carbon cloth and fully can not be utilized the problem such as not obvious with operational phase consolidation effect, cracking load and the ultimate load of its beam are less, deflection deformation within the scope of service load is larger, and bending rigidity has much room for improvement, can overcome the above problems with the strenthening member of prestressed carbon cloth technology.Therefore, for the problems referred to above, we propose the fiber cloth reinforced structure of a kind of power.
Utility model content
Prior art can not meet the needs of people, for making up prior art deficiency, the utility model aims to provide the more non-prestressed test specimen of a kind of deflection deformation within the scope of service load to be had and obviously reduces, bending rigidity obtains large increase, loss of prestress is little, easy to operate, improve cracking load and the ultimate load of reinforcement, the fiber cloth reinforced structure of practical power.
For achieving the above object, the utility model by the following technical solutions: the fiber cloth reinforced structure of a kind of power, at least comprises reinforcement, beam-ends post, force snesor, anchor plate, glass fiber, bolt and stretch-draw steel plate; Described beam-ends column symmetry is arranged on reinforcement both sides; Described reinforcement is arranged on directly over anchor plate, and reinforcement traverse beam newel post; Described anchor plate to be symmetricly set on inside beam-ends post and with beam-ends post compact siro spinning technology; Described glass fiber is closely rabbeted in the middle of anchor plate and reinforcement; Described stretch-draw steel plate to be symmetricly set on outside beam-ends post and to be connected with beam-ends post; Described force snesor is arranged on outside stretch-draw steel plate, and by bolt and stretch-draw steel plate immediately.
As optimisation technique scheme of the present utility model: described glass fiber pastes the tension face of concrete beam by adhesive glue; Described force snesor can show glass fiber by pulling force size.
Compared with prior art, the beneficial effects of the utility model are: the fiber cloth reinforced structure of this power, and when reinforcing carbon cloth amount is identical, non-prestressed Beams Strengthened With Carbon comparatively contrasts the cracking load of beam and ultimate load improves more than 10 respectively; And prestressed carbon cloth reinforced improve one to twice by curved test specimen cracking load, ultimate load improves more than 30 percent, and increase rate is corresponding with stress distribution.The more non-prestressed test specimen of deflection deformation within the scope of service load has and obviously reduces, bending rigidity obtains large increase, anchoring is reliable, loss of prestress is little, easy to operate, the features such as cost is low, effectively can carry out stretch-draw to carbon cloth, the high-strength performance of carbon cloth is fully used, improve cracking load and the ultimate load of reinforcement, consolidation effect also improves a lot than non-prestressed carbon cloth, can promote the use of in Practical Project, there are good economic benefit and social benefit, practical, be applicable to promoting the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, the fiber cloth reinforced structure of a kind of power, at least comprises reinforcement 1, beam-ends post 2, force snesor 3, anchor plate 4, glass fiber 5, bolt 6 and stretch-draw steel plate 7; Described beam-ends post 2 is symmetricly set on reinforcement 1 both sides; Described reinforcement 1 is arranged on directly over anchor plate 4, and reinforcement 1 traverse beam newel post 2; Described anchor plate 4 to be symmetricly set on inside beam-ends post 2 and with beam-ends post 2 compact siro spinning technology; Described glass fiber 5 closely interlocking is middle at anchor plate 4 and reinforcement 1; Described stretch-draw steel plate 7 to be symmetricly set on outside beam-ends post 2 and to be connected with beam-ends post 2; Described force snesor 3 is arranged on outside stretch-draw steel plate 7, and by bolt 6 and stretch-draw steel plate 4 immediately.
As optimisation technique scheme of the present utility model: described glass fiber 5 pastes the tension face of concrete beam by adhesive glue; Described force snesor 3 can show glass fiber 5 by pulling force size.
As Construction Principle of the present utility model: on the component needed reinforcement, carbon cloth is stretched to design load, by adhesive glue, carbon cloth is pasted the tension face of concrete beam, after adhesive curing to be bonded, carbon cloth and concrete structure are jointly stressed, set up prestressing force being reinforced in component.This prestressing force can offset the part or all of tensile stress that secondary causes by load, can make the work of carbon fiber earlier-joining like this, give full play to carbon cloth high strength feature, secondly, the antiarch that prestressing force produces can offset the initial moment of component, can crack progressing be suppressed, improve the rigidity of component and cracking strength and ultimate strength, improve the service behaviour of serviceability limit stage.By tensioning equipment fix in position during construction, stretching force reach design load two/for the moment, start even brushing impregnated resin at the bottom of beam and on carbon cloth, again with Lifting Equipment by the bottom of anchor plate jacking to beam, stretch-draw carbon cloth is to design load, at carbon fiber bottom surface even brushing one deck impregnated resin, compress with smooth template and wooden supporting handle anchor plate and carbon cloth top, and layer of plastic film is put between carbon cloth and template, prevent both from sticking together, at plastic sheeting lower berth one deck cystosepiment, what at the bottom of elimination beam, injustice caused is pasted not strongly, when impregnated resin is squeezed out, top is pressed onto position.Pull down tensioning equipment after seven days, paste u tie and press strip, construct complete.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
