Coal Abstract： structure in the longterm natural environment and under the use environment39。s function, its function is weaken inevitably gradually, our structural engineering39。s duty not 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 bee an important work. What may foresee will be the 21st century, the human building also by the concrete structure, the steel structure, the brickingup 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： Concrete structure reinforcement brickingup structure reinforcement steel structure reinforcement 1 Concrete structure reinforcement Concrete structure39。s reinforcement divides into the direct reinforcement and reinforces two kinds indirectly, when the design may act according to the actual condition and the operation requirements choice being suitable method and the necessary technology. the direct reinforcement39。s general method 1） Enlarges the section reinforcement law Adds the concretes castinplace level in the reinforced concrete member in bending pression zone, may increase the section effective height, the expansion cross sectional area, thus enhances the ponent right section anticurved, the oblique section anticuts ability and the section rigidity, plays the reinforcement reinforcement the role. In the suitable muscle scope, the concretes change curved the ponent right section supporting capacity increase along with the area of reinforcement and the intensity enhance. In the original ponent right section ratio of reinforcement not too high situation, increases the main reinforcement area to be possible to propose the plateau ponent right section anticurved supporting capacity effectively. Is pulled in the section the area to add the castinplace concrete jacket to increase the ponent section, through new Canada partial and original ponent joint work, but enhances the ponent supporting capacity effectively, improvement normal operational performance. 2 Enlarges the section reinforcement law construction craft simply, patible, 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 construction39。s wet operating time is long, to produces has certain influence with the life, and after reinforcing the building clearance has certain reduction. 2) Replacement concretes reinforcement law This law39。s merit with enlarges the method of sections to be close, and after reinforcing, does not affect building39。s clearance, but similar existence construction wet operating time long shorting。 Is suitable somewhat low or has concretes carrier39。s and so on serious defect Liang, column in the pression zone concretes intensity reinforcement. 3) the caking outsourcing section reinforcement law Outside the Baotou Steel Factory reinforcement is wraps in the section or the steel plate is reinforced ponent39。s 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 mission to cake a whole, after the reinforcement ponent, because is pulled with the pressed 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, 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 nonprotection39。s situation the high temperature place。 Is suitable does not allow in the use obviously to increase the original ponent section size, but requests to sharpen its bearing capacity large scale the concrete structure reinforcement. 4) Sticks the steel reinforcement law Outside the reinforced concrete member in bending sticks the steel reinforcement is (right section is pulled in the ponent supporting capacity insufficient sector area, right section pression zone or oblique section) the superficial glue steel plate, like this may enhance is reinforced ponent39。s 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 with the life influence, and after reinforcing, is no
