The invention discloses a composite material beam joint. The composite material beam joint comprises a beam flange (2) and a beam web (3), wherein the beam web (3) comprising a sandwich (4) and a loadtransmission link (1) together as an intermediate sandwich of the beam web (3), the load transmission link (1) being arranged in the longitudinal direction of the beam, the load transmission link (1)comprising a link (5), an intermediate piece (6) and a bushing (7), and the chain link (5) being sheathed on the bushing (7), the middle piece (6) fills the remaining space in the chain ring (5), andthe lining (7) and a connecting hole in a panel of the beam web (3) are equal in size and coaxial. According to the composite material beam joint, the load transmission chain ring is added in the composite material beam to reduce the edge distance and the end distance of the connecting lugs of the beam joint, so the connecting height is increased, connecting efficiency is improved, the weight isreduced, and the application mode of the composite material beam is increased.
本发明公开一种复合材料梁接头,包括梁突缘(2)和梁腹板(3),其中梁腹板(3)包括一起作为梁腹板(3)的中间夹层的夹芯(4)和载荷传递链环(1),载荷传递链环(1)沿梁的纵向方向布置,所述载荷传递链环(1)包括链环(5)、中间件(6)和衬套(7),其中链环(5)套在衬套(7)上,中间件(6)填充链环(5)内的剩余空间,所述衬套(7)与梁腹板(3)的面板上的连接孔等大且同轴。本发明通过在复合材料梁中加入载荷传递链环来减小梁接头连接耳片的边距和端距,加大了连接高度,提高了连接效率,减轻了重量,增加了复合材料梁的应用方式。
