在砖石结构施工中,砌体留槎对建筑物抗震性能起着相当重要的作用。在《工业与民用建筑抗震设计规范》第35条和《砌体工程施工及验收规范》第67条中,都强调纵横墙交接处应同时咬槎砌筑,且地震区应设置拉结筋。大量震害调查表明,凡是纵横墙不同时砌筑、不拉结、不留斜槎者,砌体都产生较严重的破坏。但是,纵横墙同时砌筑及留斜槎的问题,在施工中是一个不大好解决的问题,相当多的施工单位仍然采用直槎砌筑。这不能不引起我们的重视。
In masonry construction, masonry retention plays an important role in the seismic performance of buildings. In Article 35 of the Code for Seismic Design of Industrial and Civil Buildings and Article 67 of the Code for Construction and Acceptance of Masonry Buildings, it is emphasized that the interface between the vertical and horizontal walls should be bitten and masonry at the same time. A large number of earthquake damage investigations have shown that any masonry wall that is not masonry at the same time, does not pull knots, and does not leave slanting bricks will cause serious damage. However, the problem of simultaneously laying masonry walls and retaining skewers at the same time is a problem that is not well solved in construction. A considerable number of construction units still use straight masonry. This cannot but arouse our attention.
