The invention belongs to the field of composite material wallboard design, and provides a stiffened wallboard which comprises a first skin, a second skin and a connecting piece, a first stringer is arranged at the top of the first skin, a second stringer is arranged at the top of the second skin, the first skin is connected with the bottom of the second skin through the first stringer, and the second skin is connected with the connecting piece through the second stringer. The first stringers and the second stringers are distributed in a staggered mode, the connecting pieces are connected with the first skin through the first transverse connecting band plates or connected with the second skin through the second transverse connecting band plates, and connection of the first skin or the second skin is achieved. According to the scheme, the two connected wall plate layers are designed, so that larger out-of-plane loads can be borne in the thickness direction, and the structural stability is improved; and the stringers are distributed in a staggered manner, so that bearing force can be more uniformly distributed in a limited space, the stress caused by out-of-plane load is uniformly transmitted to the two wall plate layers, and the structural stability is further improved.

    本发明属于复合材料壁板设计领域,提供了一种加筋壁板,包括第一蒙皮、第二蒙皮和连接件,所述第一蒙皮顶部设置有第一长桁,所述第二蒙皮顶部设置有第二长桁,所述第一蒙皮通过第一长桁与所述第二蒙皮的底部连接,以使所述第一长桁与所述第二长桁交错分布,连接件通过第一横向连接带板连接第一蒙皮或通过第二横向连接带板连接第二蒙皮,实现对于第一蒙皮或第二蒙皮的接续。本案设计相连的两个壁板层,使得在厚度方向上能够承受更大的面外载荷,结构稳定性得到提高;并且长桁之间交错分布,能够在有限的空间内更均匀地布置承力,使得面外载荷所造成的应力被均匀传递到两个壁板层,结构稳定性进一步提高。
