engineering39。 But scene construction39。 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 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 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 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。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。s reinforcement。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。 放大段加固法施工工藝簡(jiǎn)單,兼容,并具有成熟的設(shè)計(jì)和施工經(jīng)驗(yàn),在梁,板,柱,墻和一般結(jié)構(gòu)用混凝土加固 。 10 該法施工速度快,現(xiàn)場(chǎng)工作或不濕上只有少數(shù)濕抹灰工程等,對(duì)生產(chǎn)與生活的影響小,經(jīng)過加強(qiáng)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。 作為水平提升干的函數(shù)的結(jié)果,原來的組件的部分由收到彎曲應(yīng)力的特點(diǎn)變成了偏心受壓,因此,在加固,組件的配套能力,主要是在彎曲決定的條件下,原始組件的配套能力。與傳統(tǒng)做法相比,具有施工時(shí)間短,費(fèi)用低,影響和 對(duì)案情非 11 常輕微對(duì)生活和生產(chǎn),但高到規(guī)范,必須完成由熟練的工人,可以確保安全。 5)混凝土表面處理技術(shù) 它是指采用混凝土表面的污漬清理,油痕,殘以及其他附件和化學(xué) 法,機(jī)械法,噴砂法,真空清洗方法,注射的方法技巧等。它的優(yōu)點(diǎn)和外部的鋼筋混凝土疊合層加固法相近,但提高配套能力不如前者 。 3)砌體式開啟部分基礎(chǔ) 當(dāng)房子部分破損,但經(jīng)過深入調(diào)查時(shí),其斷裂的原因尚未影響承重和安全性,可以燎原墻部分拆除,并根據(jù)對(duì)提高砂漿強(qiáng)度的第一級(jí),以填補(bǔ)與全尺寸磚基礎(chǔ)。 4)裂紋修復(fù)與加固 由于結(jié)構(gòu)的負(fù)載影響和材料的 選擇,結(jié)構(gòu),制造,工作一再不當(dāng)?shù)壬a(chǎn),并有休息時(shí)間延長(zhǎng)或清脆的傾向性裂紋損傷,應(yīng)盡量修復(fù)。 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(jì)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。 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。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??芍踩肫胀ㄤ摻?,也可植入螺栓式錨肌肉 。 此法可減少是鋼筋構(gòu)件的應(yīng)力水平,不僅使加固效果好,而且還能大范圍提高結(jié)構(gòu)的整體配套能力,但經(jīng)過加固,有一定的影響,對(duì)原結(jié)構(gòu)外觀,適合作為以及在高壓力,高緊張狀態(tài)混凝土構(gòu)件的加固,在大跨度或重型結(jié)構(gòu)加固,但在非保護(hù)的情況下,不能使用在上述環(huán)境中的 600℃的溫度,也沒有合適的用途不斷變化的混凝土收縮大結(jié)構(gòu) 。除了具有類似膠水的鋼板的優(yōu)點(diǎn),又具有防腐泥濘,耐潮濕,不增加自身結(jié)構(gòu)重量近,耐用,維護(hù)費(fèi)用低等優(yōu)點(diǎn),但需要特殊的防火處理,是適合各種應(yīng)力混凝土結(jié)構(gòu)構(gòu)件的性質(zhì)和一般建設(shè)。 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 筑物的清拆,但同樣存在施工濕作業(yè)時(shí)間長(zhǎng)的缺點(diǎn) 。什么可以預(yù)見將是 21世紀(jì),人類建筑的混凝土結(jié)構(gòu),鋼結(jié)構(gòu),砌體式結(jié)構(gòu)等為主另外,現(xiàn)階段我會(huì)覺得在結(jié)構(gòu)加固我們這方面的研究也應(yīng)借 此作為主要的突破方向。s bearing capacity, and the reinforcement effect is reliable。 Is suitable in had in the building each kind of crack processing, but to the stress crack, besides patching, still should use the corresponding reinforcement measure. The internal patching law is with the forcing pump the ceme nting material pressure concretes crack, renders the young or up and ing generation to sew up the function, and makes the original structure through its cementation to restore the integrity, this method is suitable for the crack opening is big, and durable and so on is influential to the structure integrity and the security, or has request and so on waterproof antiseepage crack patching. 4) Carbonized concretes repair technology It is refers to through restores the concretes the alkalinity (inactivation) or increases its impedance to enable the steel bar corrosion which the carbonization creates to obtain the containment technology. 5) Concretes surface treatment technology It is refers to uses cleaning up concretes surface stains, the oil mark, the residual as well as the other attachment and so on chemistry method, mechanical method, sand blasting method, vacuum cleaning method, injection method skill. 6) Coagulation mantle of soil seal technology It is refers to uses flexible methods and so on aquaseal backfill, polymer grouting, paint film to carry on the waterproofing to the concretes, moistureproof and against crack processing technology. Like the structure, the ponent shift the technology, t
