Cavity wall
The invention provides a cavity wall, a functional wall structure, a wall structure with a window, a wall structure with a bay window and a connecting joint structure of a building. The cavity wall comprises a first prefabricated plate, a second prefabricated plate, and a connecting structure. The first prefabricated plate and the second prefabricated plate are oppositely arranged. The connecting structure is connected between the first prefabricated plate and the second prefabricated plate, so that a cavity is formed between the first prefabricated plate and the second prefabricated plate; the inner side face of the first prefabricated plate and/or the inner side face of the second prefabricated plate are/is provided with a rough structure, and the rough structure comprises a plurality of parallel grooves extending in the transverse direction. According to the cavity wall, the contact area between prefabricated concrete and cast-in-place concrete can be increased, so that the connecting strength of the prefabricated concrete and the cast-in-place concrete is enhanced, meanwhile, the transversely-formed grooves can play a proper role in limiting coarse aggregate in the cast-in-place concrete, the coarse aggregate is prevented from sinking and concentrating under the conditions of gravity and vibration, cast-in-place concrete is uniform in density, and structural stability is improved.
本发明提供了一种空腔墙、功能墙结构、带窗口的墙结构、带飘窗的墙结构以及建筑物的连接节点结构。其中，空腔墙包括：相对设置的第一预制板和第二预制板；连接结构，连接在第一预制板和第二预制板之间，以使第一预制板和第二预制板之间形成空腔；其中，第一预制板的内侧面和/或第二预制板的内侧面具有粗糙结构，粗糙结构包括多个并行的，沿横向延伸的凹槽。本发明的空腔墙能够增加预制混凝土和现浇混凝土之间的接触面积，从而加强二者的连接强度，同时，横向设置的凹槽能够对现浇混凝土中的粗骨料起到适当的限制作用，防止粗骨料因重力和振捣的情况下下沉集中，保证现浇混凝土密度均匀，提高结构稳定性。
