Prefabricated light sandwich wallboard
The invention discloses a prefabricated light sandwich wallboard, and belongs to the technical field of house building energy-saving materials. A plurality of FRP ribs arranged on an outer concrete ribbed plate penetrate through a plurality of through holes II formed in a heat preservation layer and a plurality of through holes I formed in an inner concrete ribbed plate and are matched with an anchorage device to connect the inner concrete ribbed plate, the outer concrete ribbed plate and the heat preservation layer into a whole. The inner and outer concrete ribbed plates are thin (the slab thickness is 14 mm, and the slab rib thickness is 11 mm), so that the quality and the cost of the sandwich wallboard are greatly reduced. Secondly, under the action of the FRP ribs, the heat preservation layer, the inner concrete ribbed plate and the outer concrete ribbed plate conduct load transmission through slab rib contact faces, and the integrity is good; the problem of stress concentration caused by a traditional connecting piece is solved, microcracks are reduced, and durability is good; and meanwhile, cold and thermal bridge effects are avoided, and the heat preservation efficiency is high.
一种预制轻质夹芯墙板，属于房屋建筑节能材料技术领域。本发明通过外叶混凝土加肋板上设有的多个FRP筋穿过保温层上设有的多个通孔二以及内叶混凝土加肋板上设有的多个通孔一并与锚具配合将内叶混凝土加肋板、外叶混凝土加肋板、保温层连接为一体。本发明内、外叶混凝土加肋板薄(平板厚度为14mm，板肋厚度为11mm)，这极大地降低了夹芯墙板的质量和成本。其次，在FRP筋的作用下，保温层和内、外叶混凝土加肋板通过板肋接触面进行荷载传递，整体性好；也克服了传统连接件所带来的应力集中问题，减少了微裂纹的出现，耐久性好；同时，无冷、热桥效应，保温效率高。
