Prestressed PC truss bidirectional laminated slab
The prestressed PC truss bidirectional laminated slab comprises a laminated slab body and a mold, an L-shaped connecting piece is installed at the joint of the mold through screws, a plurality of through holes are formed in the surfaces of the two sides of the mold at equal intervals, first steel bars penetrate through the through holes, through holes are formed in the other surfaces of the two sides of the mold at equal intervals, and second steel bars penetrate through the through holes. Third steel bars are installed at the positions, close to the inner wall of the mold, of the two sides of the second steel bars at equal intervals, steel wires are bundled at the joints of the first steel bars, the second steel bars and the third steel bars, and a plurality of truss rib structures are arranged at the gaps of the first steel bars, the second steel bars and the third steel bars and comprise upper chord ribs and lattice ribs. According to the prefabricated composite slab, truss ribs in an existing prefabricated composite slab and prestressed ribs in a PK slab are combined, the early-stage construction process is simplified, and the early-stage cost and labor input are reduced.
本发明公开了预应力PC桁架双向叠合板，包括叠合板本体和模具，模具的连接处通过螺钉安装有L型连接件，模具的两侧表面等距开设有若干通孔，通孔内均贯穿设有第一钢筋，模具的两侧另表面等距开设有通孔，通孔内贯穿设有第二钢筋，第二钢筋的两侧在靠近模具内壁之间等距安装有第三钢筋，且第一钢筋、第二钢筋和第三钢筋的连接处捆扎有钢丝，第一钢筋、第二钢筋和第三钢筋的间隙处设有若干组桁架筋结构，桁架筋结构包括上弦筋和格构筋组成，格构筋的顶部焊接有上弦筋，且格构筋呈波浪形形状，本发明将现有预制叠合板中桁架筋和PK板中预应力筋相结合，使前期施工工艺得到简化，降低前期成本和劳动力的投入。
