本发明涉及一种应用于外挂体系的单面叠合墙板，包括单面叠合外挂板、具有桁架纵杆、桁架下弦筋和桁架腹杆的桁架、外墙连接机构；桁架腹杆一端与桁架下弦筋焊接并预埋在单面叠合外挂板中，另一端与桁架纵杆焊接；桁架竖直间隔分布在单面叠合墙板背面；外墙连接机构部分预埋在单面叠合外挂板，部分预埋在现浇梁内，并同时与桁架固定连接。本发明通过桁架腹杆、桁架纵杆和桁架下弦筋组成辅助支撑结构，与混凝土墙板之间形成一定间距，可保证外挂墙体的整体厚度，减轻外挂墙体的整体重量，桁架的存在提高了外挂板的刚度和侧向抗剪能力，保证了外挂墙板的稳定性；同时还可以通过附加预应力来调节整个单面叠合外挂板的厚度。

The invention relates to a single-sided laminated wallboard applied to an external hanging system. The single-sided laminated wallboard comprises a single-sided laminated external hanging board, trusses and an external wall connecting mechanism, wherein each truss is provided with a truss longitudinal rod, a truss lower chord rib and a truss web member; one end of each truss web member is welded with the corresponding truss lower chord rib and is embedded in the single-sided laminated external hanging board, and the other end of each truss web member is welded with the corresponding truss longitudinal rod; the trusses are vertically distributed on the back surface of the single-sided laminated wallboard at intervals; and the external wall connecting mechanism is partially embedded in the single-sided laminated external hanging board, is partially embedded in a cast-in-place beam and is fixedly connected with the trusses. According to the single-sided laminated wallboard disclosed by the invention, an auxiliary supporting structure is formed by the truss web members, the truss longitudinal rods and the truss lower chord ribs, and a certain distance is formed between the auxiliary supporting structure and a concrete wallboard, so that the overall thickness of an external hanging wall body can be guaranteed, and the overall weight of the external hanging wall body is reduced; and due to the existence of the trusses, the rigidity and the lateral shear-bearing capacity of the external hanging board are improved, and the stability of the external hanging wallboard is guaranteed; and meanwhile, the thickness of the whole single-sided laminated external hanging board can be adjusted by additional prestress.
