构造柱如何砌筑？构造柱有何作用？ - 工程施工 - 项目管理 - 氿上知道

（2）在多层砌体房屋,底层框架及内框架砖砌体中,它的作用一般为:加强纵墙间的连接,是由于构造柱与其相邻的纵横墙以及牙搓相连接并沿墙高每隔500mm 设置2 (6 拉结筋,钢筋每边伸入墙内大于100mm。一般施工时先砌砖墙后浇筑混凝土柱,这样能增加横墙的结合,可以提高砌体的抗剪承载能力10 % —30 % ,提高的比例幅度虽然不高但能明显约束墙体开裂,限制出现裂缝。构造柱与圈梁的共同工作,可以把砖砌体分割包围,当砌体开裂时能迫使裂缝在所包围的范围之内,而不至于进一步扩展。砌体虽然出现裂缝,但能限制它的错位,使其维持承载能力并能抵消振动能量而不易较早倒塌。砌体结构作为垂直承载构件,地震时最怕出现四散错落倒地,从而使水平楼板和屋盖坠落,而构造柱则可以阻止或延缓倒塌时间、以减少损失。构造柱与圈梁连接又可以起到类似框架结构的作用,其作用效果非常明显。构造柱不是砌筑的，是用混凝土浇筑而成的。
