Wood structure cross beam based on self-tightening dovetail joint and construction method thereof
The invention discloses a wood structure cross beam based on self-tightening dovetail tenons and a construction method thereof.The cross beam comprises a cross beam body formed by connecting a main beam and a secondary beam, the joint face of the main beam and the joint face of the secondary beam are each provided with at least one group of mortises and tenons which are matched with each other, and the shape of each tenon is a semi-ellipse formed by dividing the ellipse into a short axis; the root of the tenon is narrow, and the end of the tenon is wide. According to the large-span wood beam, the main beam and the secondary beam can be correspondingly connected to form the cross beam through the semi-elliptical tenon and the tenon groove which are respectively arranged on the main beam and the secondary beam and have narrow roots and wide ends, so that the problem that the bearing capacity is reduced due to drilling on the beam is avoided, and the bearing capacity of the large-span wood beam and the integrity of a wood structure are improved. And the mortises and the tenons only need to be manufactured on the primary beam and the secondary beam in the machining process, any reinforcing pieces and connecting pieces do not need to be additionally arranged at the connecting parts, wood loss is small, and assembling materials are saved. The self-tightening dovetail joint connection mode is adopted, installation is convenient and fast, installation precision is high, wood structure installation integrity is good, and appearance quality is good.
本发明公开一种基于自紧式燕尾榫的木结构井字梁及其施工方法，井字梁包括主梁和次梁连接形成的井字梁，所述主梁和次梁的接合面上分别设有至少一组相适配的榫槽和榫头，所述榫头的形状是将椭圆形通过短轴分成的半椭圆形，且所述榫头根部窄、端部宽。通过主梁和次梁上分别设置的半椭圆形且根部窄、端部宽的榫头和榫槽，可将主梁和次梁对应相接形成井字梁，避免在梁上钻孔造成的承载力降低问题，提高了大跨度木梁的承载能力和木结构的整体性。只需要在加工过程在主次梁上进行榫槽和榫头的制作，无需在连接部位增加任何加固件和连接件，木材损耗小，并节省组装材料。采用自紧式燕尾榫连接方式安装方便快捷、安装精度高，木结构安装整体性好，观感质量好。
