混凝土的加固Ҏ有很多种Q而且应用范围是比较广泛的Q大家也是经常可以在建筑工程中看见的Q前期的混凝土加固对于徏{质量来说是比较关键的,所以对于؜凝土的加固方法我们要掌握的多一点,下面<strong class="htjdf"><b>沛_加固公司</b></strong>来带大家了解一下?</p> <p style="text-align:center;"> <img

该法适用于؜凝土强度{为C20~C60的؜凝土扉Kl构的改造、加?不适用于已严重风化的上q结构及轻质l构?br />     2、粘钢加固法<br />     钢筋混凝土受弯构件外部粘钢加固是在构件承载力不区段(正截面受拉区、正截面受压区或斜截?表面_脓钢板Q这样可提高被加固构件的承蝲力,且施工方ѝ适用于承受静力作用且处于正常湿度环境中的受弯或受拉构件的加固?br />     3、置换؜凝土加固?br /> <p>     该法的优点与加大截面法相q,且加固后不媄响徏{物的净I,但同样存在施工的湿作业时间长的缺?适用于受压区混凝土强度偏低或有严重缺L梁、柱{؜凝土扉K构g的加固?</p> <p style="text-align:center;"> <img src="/uploads/image/20190304/20190304110129_4189.jpg" alt="" /> </p>     4、有_结外包型钢加固?br />     外包钢加固是把型钢或钢板包在被加固构件的外边Q外包钢加固钢筋混凝土梁一般应采用湿式外包法,即采用环氧树脂化灌浆{方法把型钢与被加固构䄦_结成一整体Q加固后的构Ӟ׃受拉和受压钢截面面积大幅度提高,因此正截面承载力和截面刚度大q度提高?br />     5、加大截面加固法<br />     在钢{؜凝土受弯构g受压区加混凝土现层Q可增加截面有效高度Q扩大截面面U,从而提高构件正截面抗弯Q斜截面抗剪能力和截面刚度,起到加固补强的作用。加大截面加固法施工工艺单、适应性强Qƈh成熟的设计和施工l验;适用于梁、板、柱、墙和一般构造物的؜凝土的加?但现场施工的湿作业时间长Q对生和生zL一定的影响Q且加固后的建筑物净I有一定的减小?br />     6、粘贴纤l增强塑料加固法<br /> <p>     外脓U维加固是用胶结材料把纤l增强复合材料脓于被加固构g的受拉区域,使它与被加固截面共同工作Q达到提高构件承载能力的目的。除h_脓钢板怼的优点外Q还h耐腐、耐潮ѝ几乎不增加l构自重、耐用、维护费用较低等优点Q但需要专门的防火处理Q适用于各U受力性质的؜凝土l构构g和一般构{物?</p> <p style="text-align:center;"> <img
