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。適合在不允許增加原構(gòu)件截面尺寸,其實(shí)要求提高部分配套能力的大型砌體式柱的加固,其缺點(diǎn)是費(fèi)用高的鋼筋,而必須使用類似鋼結(jié)構(gòu)的防護(hù)措施。 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。適合于有在建筑物裂縫處理每一種,但對應(yīng)力裂紋修補(bǔ)之外,還應(yīng)該使用相應(yīng)的加固措施。是在混凝土結(jié)構(gòu)加固混凝土許可期限合適。 7)錨桿錨固法方 這項(xiàng)法律是在合適的混凝土強(qiáng)度等級為 C20 的混凝土 ? C60 的承重成員改造,加固,它已經(jīng)不適合上述結(jié)構(gòu),素質(zhì)結(jié)構(gòu),光認(rèn)真適合很體面。 該法還表示,包頭鋼鐵廠外濕加固法,應(yīng)力可靠,施工簡便,現(xiàn)場工作量小,但與鋼材數(shù)量大,不宜在上面,在非 600℃用途 ,保護(hù)的形勢高溫場所 。 在適當(dāng)?shù)募∪夥秶淖兓炷翉澢慕M件的右側(cè)部分配套能力,隨著鋼筋面積和強(qiáng)度的提高增加。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 5 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。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。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。 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. 7) Fang bolt anchor law This law is suitable in the concretes intensity rank is the C20~C60 concretes loadbearing member transformation, the reinforcement。s supporting capacity 。s original condition and the use function, possibly and reduces uses the space。 Has widely applied in
