【正文】 had building39。 Is suitable in the brickingup wall reinforcement, sometimes also uses in outside the reinforced concrete when the superimposed layer reinforcement belt engaged column wall the both sides put on the wall stirrup the seal. 3) the addition holds the engaged column reinforcement law This law belongs enlarges the section reinforcement method one kind. Its merit the superimposed layer reinforcement law is also close with the reinforced concrete outside, but the supporting capacity enhances limitedly, and difficult to satisfy the earthquake resistance request, generally only in peneseismic country application. suitable for the brickingup structure indirect reinforcement method 1) noncaking outsourcing section reinforcement law This law belongs to the traditional reinforcement method, its merit is the construction is simple, the scene work load and the wet work are few, the stress is more reliable。s main method includes: Reduces the load, the change structure putation graph, to enlarge the original structural unit section and the joint strength, the impediment fracture growth and so on. When has the mature experience, may also use other reinforcement method. 1) changes the structure putation graph The change structure putation graph39。 在原來的組件的右側(cè)部分鋼筋的比例不太高的情況,增加了主要加固面積有可能提出的高原組件的右側(cè)部分抗彎曲能力,有效地支持。適合不允許在使用明顯增加原構(gòu)件截面尺寸,但要求以增強(qiáng)其承載能力的大 型混凝土結(jié)構(gòu)的加固。 間接加固的一般方法 1)預(yù)應(yīng)力加固法 ( 1) Thepre,強(qiáng)調(diào)加強(qiáng)橫向拉桿彎曲混凝土的成員,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)降低,從而激化組件的抗彎曲能力。 與混凝土結(jié)構(gòu)加固改造配套使用的技術(shù) 一般 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 。內(nèi)部修補(bǔ)法與強(qiáng)制泵壓混凝土膠凝材料的裂紋,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,這種方法是合適的裂縫開口大,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。其優(yōu) 點(diǎn)是施工工藝簡(jiǎn)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(chǎng)施工濕作業(yè)時(shí)間長,對(duì)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。 12 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。 鋼結(jié)構(gòu)加固一般采用焊接接頭連接,高強(qiáng)度螺栓連接摩擦適當(dāng)?shù)?,有基礎(chǔ)的時(shí)候也可以使用摩擦焊接接頭和高強(qiáng)度螺栓的混合連接。 1)改變了結(jié)構(gòu)計(jì)算圖 這項(xiàng)改變結(jié)構(gòu)計(jì)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(dòng)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(shí),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(shì),并認(rèn)為已經(jīng)有缺陷和損壞情況。 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(jiǎn)單,現(xiàn)場(chǎng)的工作負(fù)荷和濕工作少,強(qiáng)調(diào)的是更可靠 。 2 砌體式結(jié)構(gòu) 砌體式結(jié)構(gòu)加固方法:砌體式結(jié)構(gòu)的加固補(bǔ)強(qiáng)到時(shí)直接和間接地分為兩種強(qiáng)化,設(shè)計(jì),可根據(jù)實(shí)際條件和使用要求選擇適宜的方法。 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,使用印章不同的保護(hù)方法進(jìn)行修補(bǔ),一種技能,會(huì)導(dǎo)致結(jié)構(gòu),因?yàn)?打擊減少使用功能,和耐久性能恢復(fù) 。該法簡(jiǎn)單可靠,但容易損害建筑物的原貌和使用功能,可能并減少使用空間 。 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成員的情況。 3)粘結(jié)外包段加固法 外包頭鋼鐵廠強(qiáng)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(qiáng)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(qiáng)段施工委員會(huì)蛋糕一個(gè)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拉,所以右側(cè)部分配套能力和部分剛性大幅度的提高。 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(huì)增加部分有效高度,擴(kuò)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(bǔ)強(qiáng)的作用。 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。 Is suitable in the column, the belt wall wall reinforcement。 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 reinforcement in the great span or the heavy structure reinforcement, but in the nonprotection39。s section stress characteristic by received bends turned the eccentric pression, therefore, after the reinforcement, 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。 Is suitable somewhat low or has concretes carrier39。s duty not just must finish the building earlier period the project work, but must be able
