Precast wallboard molded with holes formed through steel mesh formworks
The invention discloses a prefabricated wallboard with holes formed through steel mesh formworks. The prefabricated wallboard is internally provided with vertical through-long holes, the holes are formed through the dismantling-free steel mesh formworks which are formed by welding longitudinal bars or angle steel, steel mesh and transverse keel during production of the wallboard, wherein the longitudinal bars or the angle steel in the steel mesh formworks serve as vertical stress reinforcing steel bars of a wall. No reinforcing steel bars stretch out of the prefabricated wallboard in the vertical direction, additional connecting reinforcing steel bars are arranged in the holes at the joint of the upper and lower layer wallboard, and concrete is poured into the holes to realize the lap joint connection of the vertical stress steel bars of the wall; and reinforcing steel bars stretch out of the prefabricated wallboard in the horizontal direction, and the same-layer adjacent wallboards are connected through a post-pouring section. The prefabricated wallboard is convenient to produce and construct, reasonable in connection structure, and capable of solving the problems that a traditional prefabricated wallboard is difficult to produce and construct, the lap joint transmission performance is difficult to guarantee, and the like.
本发明公开了一种采用钢网模成孔的预制墙板，该预制墙板内具有竖向通长孔洞，该孔洞通过墙板生产时设置由纵筋或角钢、钢网和横龙骨焊接制成的免拆钢网模形成，钢网模中纵筋或角钢兼做墙体竖向受力钢筋。预制墙板竖向不出筋，在上下层墙板连接处的孔洞内设置附加连接钢筋，并向孔洞内浇筑混凝土实现墙体竖向受力钢筋搭接连接；预制墙板水平出筋，同层相邻墙板通过后浇段连接。本发明的预制墙板生产及施工方便，连接构造受力合理，可解决传统预制墙板存在的生产及施工困难，搭接传力性能难以保证等问题。
