【正文】 t steel structure reinforcement 1 Concrete structure reinforcement Concrete structure39。 But scene construction39。 Is suitable somewhat low or has concretes carrier39。 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。 Is suitable reinforcement which is insufficient in the concrete structure ponent oblique section supporting capacity, or must exert the crosswise binding force to the pressional member the situation. 6) Reeling law This law39。s general method 1) Prestressed reinforcement law (1)Theprestressed horizontal tension bar reinforces concretes member in bending,because the prestressed and increases the exterior load the bined action, in the tension bar has the axial tension, this strength eccentric transmits on the ponent through the pole end anchor (, when tension bar and Liang board bottom surface close fitting, tension bar can look for tune together with ponent, this fashion has partial pressures to transmit directly for ponent bottom surface), has the eccentric pression function in the ponent, this function has overe the bending moment which outside the part the load produces, reduced outside the load effect, thus sharpened ponent39。s section stress characteristic by received bends turned the eccentric pression, therefore, after the reinforcement, ponent39。s bining site transmits for is reinforced the ponent, has counterbalanced outside the part the load, changed the original ponent section endogenic force characteristic, thus sharpened ponent39。s reinforcement in the great span or the heavy structure reinforcement, but in the nonprotection39。s technology 1) The request trades the technology It is the joist (either truss) opens the column (or wall), the joist terminal and the joist trades technologies and so on column to call generally。 Compares with the traditional practices, has the construction time to be short, the expense low, affects and so on merits slightly to the life and the production, but is high to the specification, must plete by the skilled worker, can ensure the security. 2） Plants the muscle technology It is one item is simple and direct to the concrete structure, the effective connection and the anchor technology。s lengthening by joining, the house superimposed layer terminal and the highrise construction addition shearing force wall plants the muscle and so on. 3） Crack patching technology According to the concretes crack39。 Is suitable in the column, the belt wall wall reinforcement。s reinforcement。 Its 7 shorting cannot use in the temperature in the 600C above environment. brickingup structure constructivity reinforcement and patching 1) addition grid reinforcement When the grid establishment does not meet the present design code requirement, either the vertical cross wall interface point nips rubs has the obvious flaw, when either the house integrity is bad, should additionally build the grid to carry on the reinforcement 2)additionally builds the Liang pad reinforcement When under the summer beam the brick setting the wall presents by under the partial squash or the summer beam the partial vertical split, should additionally build Liang the pad to carry on the reinforcement. 3)the brickingup opens partially builds When house partial breakage but after investigating thoroughly its breakage reason when not yet affects loadbearing and the security, may burst the wall partial demolition, and according to enhances the mortar strength firstlevel to fill in with the full sized brick builds. 4)brickingup crack patching Before carrying on crack patching, should act according to brickingup ponent39。s choice, should the reason which, the goal, the stress condition, the structure and the execution conditions needs to reinforce according to the structure, and considers the structure original connection method determination. The steel structure reinforcement general uses the welded joint connection, the friction high strength bold fastening suitably, has when the basis may also use the welded joint and the friction high strength bolt39。 直接加固的一般方法 1）放大段加固法 添加混凝土現(xiàn)澆鋼筋發(fā)生水平彎曲受壓區(qū)混凝土構(gòu)件，可能會增加部分有效高度，擴大截面面積，從而提高了組件的右側(cè)部分反彎，斜截面抗切割能力 部分剛度，起到加固補強的作用。 放大段加固法施工工藝簡單，兼容，并具有成熟的設(shè)計和施工經(jīng)驗，在梁，板，柱，墻和一般結(jié)構(gòu)用混凝土加固 。 3）粘結(jié)外包段加固法 外包頭鋼鐵廠強化是在部分或鋼板包裹是鋼筋構(gòu)件的外，境外包頭鋼鐵廠強化鋼筋混凝土梁使用濕外包法律一般，即采用環(huán)氧樹脂化中的牛奶等上與方法，以加強段施工委員會蛋糕一個整體，加固后的組件，因為是壓縮鋼橫截面面積大幅度提高拉，所以右側(cè)部分配套能力和部分剛性大幅度的提高。 10 該法施工速度快，現(xiàn)場工作或不濕上只有少數(shù)濕抹灰工程等，對生產(chǎn)與生活的影響小，經(jīng)過加強的，是不顯著原有結(jié)構(gòu)的外觀和原定清拆影響，但加固效果是決定由膠粘工藝和操作水平很大程度上，是在合適的承受靜態(tài)函數(shù)，而在正常的濕度環(huán)境 是彎曲或拉構(gòu)件加固。
