Wood structure roof cantilever secondary beam structure combining mortise and tenon joints and self-tapping screws
The invention discloses a wood structure roof cantilever secondary beam structure combining mortise and tenon joints and self-tapping screws. The wood structure roof cantilever secondary beam structure comprises a main beam and secondary beams, wherein the secondary beams are connected to the two sides of the main beam, connecting plates are arranged at the tops of the secondary beams, the secondary beams are connected with the connecting plates through the oblique self-tapping screws, bending moment transmission is achieved, and shearing force transmission is achieved through mortise and tenon joint connection. The wood structure roof cantilever secondary beam structure has the advantages that the main beam and the secondary beams are connected through mortise and tenon joint nodes on the side faces, the problem that a wood roof is thick due to lap joint can be solved, and the height of the roof is reduced; grooves are formed in the upper sides of the main beam and the secondary beams, the depth of the grooves is the same as the thickness of the connecting plates, the connecting plates and the top faces of the main beam and the secondary beams are located at the same elevation, and the overall attractiveness is improved; the mortise and tenon joints are machined through numerical control machining equipment, and machining precision can be guaranteed; the self-tapping screws are adopted at the mortise and tenon joint connecting positions for local reinforcement, and shearing force transmission is guaranteed; and bending moment transmission is achieved through the combination of the connecting plates and the self-tapping screws, the structural strength and stability of the secondary beams are improved, and the cantilever requirement of the secondary beams is met.
本发明公开了一种采用榫卯和自攻螺钉相结合的木结构屋盖悬挑次梁结构，包括主梁和次梁，主梁的两侧连接有次梁，次梁顶部设置有连接板，通过斜自攻螺钉将次梁与连接板连接，实现弯矩的传递，通过榫卯连接实现剪力的传递。本发明的优点：利用侧面的榫卯节点实现主、次梁的连接，能减小搭接造成的木屋盖较厚的问题，减少屋盖的高度；主、次梁上侧设有凹槽，凹槽深度与连接板厚度相同，使连接板与主、次梁顶面在同一标高，提高整体美观性；采用数控加工设备进行榫卯的加工，能保证加工精度；榫卯连接处采用自攻螺钉进行局部加强，保证剪力的传递；利用连接板和自攻螺钉的组合，实现弯矩的传递，提高次梁的结构强度和稳定性，满足次梁的悬挑需求。
