河北房屋加固混凝土柱的加固中,有多种加固方式可供选择,其中比较有代表性的分别是增大截面加固法、外粘型钢加固法、碳纤维布加固法,三种方法各具特色,在加固时需根据具体情况进行选择。

1、增大截面加固法通过增加结构截面面积与配筋来提高结构承载力,其使用经验丰富,在梁、板、柱上均有较广泛的应用。在混凝土加固中,增大截面法尤其适用于因柱体截面较小导致承载力不足的情况。为使增大截面法在混凝土中达到最佳的加固效果,需要保证混凝土基材强度等级不能低于C13,加固用受力钢筋不应小于14mm,同时种类、截面形式、受力情况不同的混凝土柱,需要采用不同的构造形式。

河北房屋加固哪家做的好?

河北房屋加固碳纤维布加固效果较好、几乎不增加自重且施工方便,但不适用于小偏心受压构件,且对轴心受压构件加固中,还需注意柱体长细比与截面是否满足要求。因此在选择碳纤维布加固前,需要对混凝土柱有较深的了解,以避免不满足碳纤维布加固前提。
