近几年,在哈市普通砖混结构住宅建筑中所采用的砖包钢筋混凝土抗震构造柱,由于浇捣的原因,产生了一些质量问题,影响到正常的功能使用.为减少同类问题的发生、根据近几年在较大住宅小区实际工程施工和管理过程中的一点体会提供给大家,仅供参考.根据省、市有关规定,哈尔滨市抗震构造柱是沿外墙设置在墙转角及纵横墙交接处.多采用内外120实心砖模,包240×240钢筋混凝土构造柱.由于砖包模中混凝土质量浇筑后无法检查,所以当柱浇筑、振捣不密实,常常出现蜂窝,狗洞,断层,影响结构强度,产生严重的结构隐患.影响砖包摸.
In recent years, the brick-clad reinforced concrete seismic structural columns used in ordinary brick-concrete residential buildings in Harbin have caused some quality problems due to pouring, affecting the normal use of functions. To reduce the occurrence of similar problems, According to the relevant regulations of the province and city, the earthquake resistant structural pillars of Harbin City are located along the external wall at the wall corners and vertical and horizontal walls. At the junction, multiple internal and external 120 solid brick molds are used, including 240×240 reinforced concrete structural columns. Since the quality of the concrete in the brick package mold cannot be inspected after pouring, the honeycomb, dog hole, and fault often appear when the column is poured and vibrated. , affect the structural strength, resulting in serious structural hidden dangers.
