在建筑施工中,常常由于材料长度不够,需要把一些方木或圆木对接后使用。常见的对接方法有单面燕尾榫接法(图1)、斜接法(图2)、上下槎接法(图3)等。这几种对接方法在结构和外观上都存在一定缺陷。现介绍一种木料对接方法——四面燕尾榫接法,它在结构及工艺上有可取 In construction, often due to the lack of material length, it is necessary to use some square wood or round wood after docking. Common docking methods include single-sided dovetail attachment (Fig. 1), miter connection (Fig. 2), and upper and lower attachments (Fig. 3). These types of docking methods have some drawbacks in their structure and appearance. A method for butt joints of woods is introduced here. It has a four-sided dovetail joint, which is desirable in structure and technology.
