7、nforcement and the intensity enhance. In the original component right section ratio of reinforcement not too high situation, increases the main reinforcement area to be possible to propose the plateau component right section anti-curved supporting capacity effectively. Is pulled in the section the a

8、rea to add the cast-in-place concrete jacket to increase the component section, through new Canada partial and original component joint work, but enhances the component supporting capacity effectively, improvement normal operational performance. Enlarges the section reinforcement law construction cr

9、aft simply, compatible, and has the mature design and the construction experience; Is suitable in Liang, the board, the column, the wall and the general structure concretes reinforcement; But scene constructions wet operating time is long, to produces has certain influence with the life, and after r

10、einforcing the building clearance has certain reduction. 2) Replacement concretes reinforcement lawThis laws merit with enlarges the method of sections to be close, and after reinforcing, does not affect buildings clearance, but similar existence construction wet operating time long shortcoming; Is

11、suitable somewhat low or has concretes carriers and so on serious defect Liang, column in the compression zone concretes intensity reinforcement. 3) the caking outsourcing section reinforcement lawOutside the Baotou Steel Factory reinforcement is wraps in the section or the steel plate is reinforced

12、 components outside, outside the Baotou Steel Factory reinforces reinforced concrete Liang to use the wet outsourcing law generally, namely uses the epoxy resinification to be in the milk and so on methods with to reinforce the section the construction commission to cake a whole, after the reinforce

13、ment component, because is pulled with the compressed steel cross sectional area large scale enhancement, therefore right section supporting capacity and section rigidity large scale enhancement.This law also said that the wet outside Baotou Steel Factory reinforcement law, the stress is reliable, t

14、he construction is simple, the scene work load is small, but is big with the steel quantity, and uses in above not suitably 600C in the non-protections situation the high temperature place; Is suitable does not allow in the use obviously to increase the original component section size, but requests

15、to sharpen its bearing capacity large scale the concrete structure reinforcement. 4) Sticks the steel reinforcement lawOutside the reinforced concrete member in bending sticks the steel reinforcement is (right section is pulled in the component supporting capacity insufficient sector area, right sec

16、tion compression zone or oblique section) the superficial glue steel plate, like this may enhance is reinforced components supporting capacity, and constructs conveniently. This law construction is fast, the scene not wet work or only has the plastering and so on few wet works, to produces is small

17、with the life influence, and after reinforcing, is not remarkable to the original structure outward appearance and the original clearance affects, but the reinforcement effect is decided to a great extent by the gummy craft and the operational level; Is suitable in the withstanding static function,

18、and is in the normal humidity environment to bend or the tension member reinforcement.5) Glue fibre reinforcement plastic reinforcement lawOutside pastes the textile fiber reinforcement is pastes with the cementing material the fibre reinforcement compound materials in is reinforced the component to

19、 pull the region, causes it with to reinforce the section joint work, achieves sharpens the component bearing capacity the goal. Besides has glues the steel plate similar merit, but also has anticorrosive muddy, bears moistly, does not increase the self-weight of structure nearly, durably, the maint

20、enance cost low status merit, but needs special fire protection processing, is suitable in each kind of stress nature concrete structure component and the general construction. This laws good and bad points with enlarge the method of sections to be close; Is suitable reinforcement which is insuffici

21、ent in the concrete structure component oblique section supporting capacity, or must exert the crosswise binding force to the compressional member the situation. 6) Reeling law This laws good and bad points with enlarge the method of sections to be close; Is suitable reinforcement which is insuffici

22、ent in the concrete structure component oblique section supporting capacity, or must exert the crosswise binding force to the compressional member the situation. 7) Fang bolt anchor law This law is suitable in the concretes intensity rank is the C20C60 concretes load-bearing member transformation, t

23、he reinforcement; It is not suitable for already the above structure which and the light quality structure makes decent seriously. 1.2The indirect reinforcements general method1)Pre-stressed reinforcement law(1)Thepre-stressed horizontal tension bar reinforces concretes member in bending,because the

24、 pre-stressed and increases the exterior load the combined action, in the tension bar has the axial tension, this strength eccentric transmits on the component through the pole end anchor (, when tension bar and Liang board bottom surface close fitting, tension bar can look for tune together with co

25、mponent, this fashion has partial pressures to transmit directly for component bottom surface), has the eccentric compression function in the component, this function has overcome the bending moment which outside the part the load produces, reduced outside the load effect, thus sharpened components

26、anti-curved ability. At the same time, because the tension bar passes to components pressure function, the component crack development can alleviate, the control, the oblique section anti-to cut the supporting capacity also along with it enhancement. As a result of the horizontal lifting stems funct

27、ion, the original components section stress characteristic by received bends turned the eccentric compression, therefore, after the reinforcement, components supporting capacity was mainly decided in bends under the condition the original components supporting capacity 。(2) After the reinforced conc

28、rete component uses under the pre-stressed to support the type tension bar reinforcement decides, forms one by to reinforce the component and under supports the compound ultra statically determinate structure system which the type tension bar is composed, under the outside load and the pre-stressed

29、combined action, in the tension bar has the axial force and through (next supports and pole end anchor spot) with components combining site transmits for is reinforced the component, has counter-balanced outside the part the load, changed the original component section endogenic force characteristic

30、, thus sharpened components bearing capacity. This law can reduce is reinforced components stress level, not only causes the reinforcement effect to be good, moreover can also the great scope enhance the structure overall supporting capacity, but after reinforcing, has certain influence to the origi

31、nal structure outward appearance; Is suitable as well as is under the high stress, the high strained condition concretes components reinforcement in the great span or the heavy structure reinforcement, but in the non-protections situation, cannot use in the temperature above 600C in the environment,

32、 is also not suitable uses in the concrete shrinkage continuous variation big structure. 2)Increases the supporting reinforcement lawThe addition pivot reinforcement law is through the reduced member in bending effective span, achieves the reduced function, in is reinforced on the component to carry

33、 the effect, raises the structure load bearing level the goal. This law simple reliable, but easy to harm buildings original condition and the use function, possibly and reduces uses the space; Is suitable in the concrete term permission concrete structure reinforcement. 1.3Has generally with the concret
