【正文】 s bearing capacity, and the reinforcement effect is reliable。 Is suitable in had building39。s pressure function, the ponent crack development can alleviate, the control, the oblique section antito cut the supporting capacity also along with it enhancement. As a result of the horizontal lifting stem39。s merit with enlarges the method of sections to be close, and after reinforcing, does not affect building39。 3 鋼結(jié)構(gòu) 鋼結(jié)構(gòu)加固方法：鋼結(jié)構(gòu)加固的主要方法包括：減少負(fù)荷，改變結(jié)構(gòu)計算圖，放大部分和原 結(jié)構(gòu)單元的聯(lián)合力量，裂隙發(fā)育障礙等。 7）其他技術(shù) 像結(jié)構(gòu)，組件技術(shù)的轉(zhuǎn)移，調(diào)整結(jié)構(gòu)基頻技術(shù)等。 2）增加配套加固法 此外支點(diǎn)加固法的通過在彎曲有效跨度減少成員，達(dá)到減少功能，是在組件上進(jìn)行效果增強(qiáng)， 提高了 結(jié)構(gòu)承載水平的目的。 2）置換混凝土加固法 該法與放大優(yōu)點(diǎn)的部分方法被關(guān)閉，并經(jīng)過加強(qiáng)的，不影響建筑物的 間隙 ，但同樣存在施工 濕作業(yè)時間長的缺點(diǎn) 。 關(guān)鍵詞：混凝土結(jié)構(gòu)加固砌體式結(jié)構(gòu)鋼筋結(jié)構(gòu)加固 1） 混凝土結(jié)構(gòu)加固 混凝土結(jié)構(gòu)的加固分為直接加固，間接 加固 兩種，在設(shè)計時可根據(jù)實(shí)際條件和使用要求選擇適宜的方法和必要的技術(shù)。 6）繅絲法 此法的優(yōu)點(diǎn)和缺點(diǎn)與擴(kuò)大部分將接近法是適用于鋼筋混凝土結(jié)構(gòu)構(gòu)件的 斜截面承載力不足， 或必須施加橫向約束力的擠壓 加固 的情況。 3）裂縫修補(bǔ)技術(shù) 根據(jù)混凝土裂縫的原因，性質(zhì)和規(guī)模，使用 密封 不同的保護(hù)方法進(jìn)行修補(bǔ)，一種技能，會導(dǎo) 致結(jié)構(gòu)，因?yàn)榇驌魷p少使用功能，和耐久性能恢復(fù) 。 適合于砌體式結(jié)構(gòu)的間接加固方法 1）非結(jié)塊外包段加固法 該法屬于傳統(tǒng)的加固方法，其優(yōu)點(diǎn)是結(jié)構(gòu)簡單，現(xiàn)場的工作負(fù)荷和濕工作少， 壓力 是更可靠 。s function, its function is weaken inevitably gradually, our structural engineering39。s good and bad points with enlarge the method of sections to be close。 Is suitable as well as is under the high stress, the high strained condition concretes ponent39。s reinforcement divides into when the direct reinforcement and reinforces two kinds 5 indirectly, the design, may act according to the actual condition and the operation requirements choice being suitable method. suitable for the brickingup structure direct reinforcement method 1) outside reinforced concrete superimposed layer reinforcement law This law belongs to the pound section reinforcement method one kind. Its merit is the construction craft simple, patible, after the brickingup reinforcement, the supporting capacity has enhances greatly, and has the mature design and the construction experience。s mixed connection. When uses the welded joint connects, should use after the evaluation approval welding process and the connection material. 4) crack repair and reinforcement Because the structure the load affects and the choice of material, the structure, the manufacture, the work repeatedly improper and so on produces has the extension or breaks time crisply the tendentious crack damage, should try to repair. Before the repair, must analyze has the crack reason and the influence gravity, adopts the improvement structure practical work targetoriented or carries on the reinforcement the measure, to is not suitable uses the repair reinforcement the ponent, should give the demolition replacement. 。s cause, the character and the size, use seal differently protect the method to carry on patching, one kind of skill which causes the structure because to crack reduces the use function which and the durability can restore。s bearing capacity. This law can reduce 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 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。在修復(fù)之前，必須分析了裂縫的原因和影響的嚴(yán)重性，采取切實(shí)可行的治理結(jié)構(gòu)的工作目標(biāo)為導(dǎo)向或進(jìn)行加固措施，對不適合使用的維修加固 的組成部分，應(yīng)給予拆除更換 。 3）除持有從事柱加固法 該法擴(kuò)大了部分屬于一種加固方法?？芍踩肫胀ㄤ摻睿部芍踩肼? 栓式錨肌肉 。 5）粘膠纖維增強(qiáng)塑料加固法 外貼纖維加固與膠結(jié)材料粘貼在該組件是加強(qiáng)該地區(qū)的拉纖維增強(qiáng)復(fù)合材料，使其與一節(jié)加強(qiáng)聯(lián)合工作，達(dá)到磨練組件承載能力的目的。 什么可以預(yù)見將是 21 世紀(jì)，人類建筑 以 混凝土結(jié)構(gòu) 、 鋼結(jié)構(gòu) 、 砌體式結(jié)構(gòu)等為主 。 3）粘結(jié)外包段加固法 外 部包裹加固斷面或 鋼板， 外部 強(qiáng)化鋼筋混凝土梁 是普遍做法 ，即采用環(huán)氧樹脂等方法，以加強(qiáng)段施工 成為 一個整體，加固后的組件，因?yàn)槭菈嚎s鋼橫截面面積大幅度提高，所以部分 承載 能力和 斷 面硬度 大幅度的提高。是在混凝土結(jié)構(gòu)加固混凝土許可期限合適。 適合于砌體式結(jié)構(gòu)直接加固方法 1）外部鋼筋混凝土疊合層加固法 該法屬于復(fù)合段加固方法的一種。 1）改變了結(jié)構(gòu)計算圖這項(xiàng)改變結(jié)構(gòu)計算圖形的加固方法是指使用更改負(fù)載傳播的情況， 電力傳輸方式，節(jié)點(diǎn)性質(zhì)和邊界條件，除附件成員和支持，發(fā)揮了預(yù)應(yīng)力的考慮，措施等空間聯(lián)合行動進(jìn)行了加固，結(jié)構(gòu)的 方法 2）加大構(gòu)件截面的加固 使用時，加大強(qiáng)化了部分鋼材木材，斷面形式選擇要在加強(qiáng)規(guī)范的優(yōu)勢，并認(rèn)為已經(jīng)有缺陷 和損壞情況。 Is suitable somewhat low or has concretes carrier39。s section stress characteristic by received bends turned the eccentric pression, therefore, after the reinforcement, ponent39。 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。 Its 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)addition
