在砌筑砖墙时,门窗洞口需要通过过梁、托架和拱券来支撑,以承受上方墙体的荷载。

过梁可由钢筋混凝土或钢制角铁制成,安装简便。过梁通常隐藏在砖墙内部。

牛腿的跨度能力有限,最适合用于小开口或装饰,有时用作支撑梁的托架。

砖砌拱是一种广泛应用且具有强大结构性能的形式,但其施工需要精确。需要使用木材或钢材搭建拱胎,并且建造拱肩部分可能耗时较长。

标准砖拱需要将每块砖打磨成所需的楔形,因此建造成本较高。粗砌拱则依靠楔形的砂浆接缝来实现其曲率。

砖制造商可定制生产楔形砖,以满足各种特定形状和跨度拱门的需求。

当拱形沿其平面的垂直方向移动时,形成筒形拱顶;当同一拱形绕其垂直中线旋转时,则形成穹顶。
