【正文】 ation the high temperature place。 It is not suitable for already the above structure which and the light quality structure makes decent seriously. The indirect reinforcement39。 (2) After the reinforced concrete ponent uses under the prestressed to 3 support the type tension bar reinforcement decides, forms one by to reinforce the ponent and under supports the pound ultra statically determinate structure system which the type tension bar is posed, under the outside load and the prestressed bined action, in the tension bar has the axial force and through (next supports and pole end anchor spot) with ponent39。 Is suitable in the concrete term permission concrete structure reinforcement. generally with the concrete structure reinforcement transformation necessary use39。s reinforcement improvement project, for example: In the construction leaks buries the steel bar or the steel bar deviation designs the position the recovery, the ponent increases the section reinforcement to make up the muscle, the superstructure expands cross, goes against rises to Liang, column39。 Is suitable in does not allow to increase the original ponent section size, actually requests to enhance the section supporting capacity large scale the brickingup column39。s reinforcement method is refers to uses the change load spread condition, the power transmission way, the node nature and the boundary condition, the addition attachment member and the support, exerts the prestressed that measures and so on consideration space joint operation to carry on the reinforcement to the structure the method 2) enlarges the ponent section the reinforcement Uses enlarges when the section reinforces the steel lumber, chooses the section form to be advantageous in the reinforcement specification and considered already 7 has the flaw and the damage condition. 3) connection reinforcement and reinforcing member connection The steel structure connection method, namely the welded joint, the rivet, the ordinary bolt and the high strength bold fastening method39。s stressful condition and crack factors and so on characteristic, determined that creates the brickingup crack the reason, with the aim of carrying on crack patching targetoriented or using the corresponding reinforcement measure. 3 steel structures Steel structure reinforcement method: The steel structure reinforcement39。 Its shorting is the scene construction wet operating time is long, to produces has certain influence with the life, and after reinforcing the building clearance has certain reduction. 2) outside reinforced concrete mortar superimposed layer reinforcement law This law belongs to the pound section reinforcement method one kind. Its merit and outside the reinforced concrete the superimposed layer reinforcement law is close, but enhances the supporting capacity to be inferior to the former。 May implant the ordinary steel bar, may also 4 implant the bolt type anchor muscle。s situation, cannot use in the temperature above 600C in the environment, is also not suitable uses in the concrete shrinkage continuous variation big structure. 2)Increases the supporting reinforcement law The addition pivot reinforcement law is through the reduced member in bending effective span, achieves the reduced function, in is reinforced on the ponent to carry the effect, raises the structure load bearing level the goal. This law simple reliable, but easy to harm building39。s supporting capacity was mainly decided in bends under the condition the original ponent39。s good and bad points with enlarge the method of sections to be close。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 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。 3）連接加固，加強(qiáng)成員連接 鋼結(jié)構(gòu)連接方法，即焊縫，鉚釘，普通螺栓和高強(qiáng)度螺栓連接方法的選擇， 應(yīng)該的原因其中，目標(biāo)，應(yīng)力狀態(tài)，結(jié)構(gòu)和執(zhí)行條件的需要，以加強(qiáng)根據(jù)結(jié)構(gòu)，并考慮了結(jié)構(gòu)的原始連接方法 測定。 2）預(yù)應(yīng)力加固法撐桿跳高 此法可大范圍銳化砌體式柱的承載能力，加固效果可靠，適用于處理高壓力，高緊張狀態(tài)砌 體，在鋼筋結(jié)構(gòu)加固， 其缺點(diǎn)不能使用的溫度 600℃ 以上的環(huán)境中。其優(yōu)點(diǎn)是施工工藝簡單，兼容，后砌體 式加固，配套能力 已大大提高，并具有成熟的設(shè)計(jì)和施工經(jīng)驗(yàn)，在列，帶墻壁加固合適，它的缺點(diǎn)是現(xiàn)場施工 濕作業(yè)時(shí)間長，對生產(chǎn)與生活有一定的影響，并加強(qiáng)建筑清拆后有一定減少。 內(nèi)部修補(bǔ)法與強(qiáng)制泵壓混凝土膠凝材料 開裂 ，呈現(xiàn)年輕或行動(dòng)和未來一代縫合功能，使得通過其膠結(jié)恢復(fù)原來的結(jié)構(gòu)的完整性， 這種方法是 適 合的裂縫開口大，耐用等有影響的結(jié)構(gòu)完整性和安全性， 或有防水防滲修補(bǔ)裂縫要求等。 與混凝土結(jié)構(gòu)加固改造配套使用的技術(shù) 一起使用 1) 行業(yè)的技術(shù)要求 這是托梁（或桁架）打開列（或墻），終端的托梁和托梁和柱行業(yè)的技術(shù)叫一般左右 。 間接加固的一般方法 1）預(yù)應(yīng)力加固法 （ 1）強(qiáng)調(diào)加強(qiáng)橫向拉桿彎曲混凝土的 構(gòu)件 ，因?yàn)榍皬?qiáng)調(diào)，增加外部裝入拉桿的共同作用，有軸向張力，通過桿結(jié)束這一部分的人數(shù)上的偏心傳輸錨（當(dāng)拉桿與梁底部表面緊 密貼合板，拉桿可以尋找調(diào)整與組件一起，這股熱潮已分壓傳輸組件底部表面直接），在組件中的偏心壓縮功能，這個(gè)功能已經(jīng)克服彎矩以外的部分負(fù) 荷生產(chǎn)外荷載效應(yīng)，從而激化組件的抗彎曲能力。 該法還表示， 此 加固法，應(yīng)力可靠，施工簡便，現(xiàn)場工作量小，但 用 鋼量大，不宜在600℃ 以上高溫使 用 。在適當(dāng)?shù)?距離 范圍，隨著鋼筋面積和強(qiáng)度的提高增加 ， 混凝土 構(gòu)件 彎曲承載能力增加 。 的加固 設(shè)計(jì) 摘要 ：在長期的自然的環(huán)境下使用環(huán)境 下 ，其功能不可避免地漸漸地減弱，我們的結(jié)構(gòu)工程的責(zé)任 不只
