Steel truss prestressed precast concrete wallboard
The invention discloses a steel truss prestressed precast concrete wallboard which comprises a prestressed concrete board, a steel web member and a channel steel lower chord. Bottom plate reinforcing steel bars consisting of a plurality of longitudinal prestressed reinforcing steel bars and transverse reinforcing steel bars are arranged in the stress concrete plate; and the steel web member is continuously bent. The channel steel lower chord and the steel web member are connected together after the prestress of the concrete bottom plate is released; and the bottom of the channel steel web member truss is arranged in the concrete bottom plate. The bottom plate concrete and the channel steel web member truss are anchored to form the composite truss, the thin wall plate, the construction technology, the large span and the large width can be achieved, the component is not cracked or arched, manufacturing is easy, industrial production of the component is achieved, and the component production efficiency is improved.
本发明公开了一种钢桁架预应力预制混凝土墙板，其包括：预应力混凝土板，钢腹杆，槽钢下弦。所述应力混凝土板板内设置有由多个纵向预应力钢筋和横向钢筋组成的底板钢筋；所述钢腹杆连续弯折。所述槽钢下弦同钢腹杆在混凝土底板预应力放张后连接在一起；所述槽钢腹杆桁架底部置入混凝土底板内。本发明通过底板混凝土与槽钢腹杆桁架锚固形成复合桁架，可以实现墙板薄和施工工艺，大跨度和大宽度，构件不开裂，不起拱，制造简单，实现构件工业化生产，提高构件生产效率。
