2、t just must finish the building earlier period the project work, but must be able the science appraisal structure damage objective law and the degree, and adopts the effective method guarantee structure the security use, that the structure reinforcement will become an important work. What may forese

3、e will be the 21st century, the human building also by the concrete structure, the steel structure, the bricking-up structure and so on primarily, the present stage I will think us in the structure reinforcement this aspect research should also take this as the main breakthrough direction. Key word：

4、 Concrete structure reinforcement bricking-up structure reinforcement steel structure reinforcement 1 Concrete structure reinforcement Concrete structures reinforcement divides into the direct reinforcement and reinforces two kinds indirectly, when the design may act according to the actual conditio

5、n and the operation requirements choice being suitable method and the necessary technology. 1.1the direct reinforcements general method1）Enlarges the section reinforcement law Adds the concretes cast-in-place level in the reinforced concrete member in bending compression zone, may increase the secti

6、on effective height, the expansion cross sectional area, thus enhances the component right section anti-curved, the oblique section anti-cuts ability and the section rigidity, plays the reinforcement reinforcement the role.In the suitable muscle scope, the concretes change curved the component right

7、 section supporting capacity increase along with the area of reinforcement 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

8、 supporting capacity effectively. Is pulled in the section the area 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 per

9、formance. Enlarges the section reinforcement law construction craft 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 lo

11、 existence construction wet operating time long shortcoming; Is 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 reinfo

12、rcement is wraps in the section or the steel plate is reinforced 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

13、the construction commission to cake a whole, after the reinforcement 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 B

14、aotou Steel Factory reinforcement law, the stress is reliable, the 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 obviousl

This law construction is fast, the scene not wet work or only h

17、as the plastering and so on few wet works, to produces is small 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 oper

19、inforcement compound materials in is reinforced the component to 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

This laws good and bad points with enlarge the method of se

23、nk is the C20C60 concretes load-bearing member transformation, the 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 horizonta

24、l tension bar reinforces concretes member in bending,because the 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 surfa

25、ce close fitting, tension bar can look for tune together with component, 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 produ

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 i

27、t enhancement. As a result of the horizontal lifting stems function, 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 origin

28、al components supporting capacity 。(2) After the reinforced concrete 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 tensi

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 cap

This law simple reliable, but easy to harm buildings original condition and the use function, possibly and reduces uses the spac
