木门窗扇一般都是榫接。掩扇前,一般要在榫接处钉装铁三角和T字铁角.以增强门窗扇的整体刚度和榫接处的强度。铁三角的常用规格有边长50、60、75、80、90、100、110毫米等;T字铁角常用的规格有边长50、65、75、90、100、110等。铁三角的钉装位置一般是:外开门扇在扇活内侧,内开门扇在扇活外侧.外开窗扇在扇活外侧。钉装时,将铁三角平放在扇边梃和冒 Wooden sashes are generally spliced. Before the fan is hidden, the iron triangle and the T-shaped iron corner are generally required to be bolted at the joint to enhance the overall rigidity of the door and window fan and the strength of the joint. The common specifications of the iron triangle include side length 50, 60, 75, 80, 90, 100, 110 mm, etc.; commonly used specifications of T-shaped iron corners are 50, 65, 75, 90, 100, 110 and so on. The installation position of the iron triangle is generally as follows: the outer door leaf is inside the fan live, the inner door leaf is outside the fan live, and the outer window leaf is outside the fan live. When nailing, place the iron triangle flat on the edge of the fan.
