Prestressed truss steel bar laminated slab and production method thereof
The invention discloses a prestressed truss steel bar laminated slab, and belongs to the technical field of truss steel bar laminated slabs. The prestressed truss steel bar laminated slab comprises adie table and a die. Common steel bars and truss steel bars are arranged in the die. Each truss steel bar comprises an arc-shaped upper chord and arc-shaped lower chords which protrude upwards, wherein the upper chord and the two lower chords are arranged in parallel. A plurality of counter-force beams are arranged above the truss steel bars, and pressure beams in one-to-one correspondence with the truss steel bars are arranged on the counter-force beams. The pressure beams and the truss steel bars are arranged in parallel, and pull rods are arranged at the two ends of each counter-force beam.Turnbuckles and stress meters are arranged between the adjacent pull rods located at the same ends of the counter-force beams, and the bottom ends of the pull rods are connected with the die table. The invention further discloses a production method for the prestressed truss steel bar laminated slab. By the adoption of the prestressed truss steel bar laminated slab and the production method thereof, the mechanical property of the truss steel bars is fully exerted, the problems of arching and deflection of an existing truss steel bar laminated slab can be solved, and the bending resistance ofthe laminated slab is improved.
本发明公开了一种预应力桁架钢筋叠合板，属于桁架钢筋叠合板技术领域，包括模台和模具，模具内设置有普通钢筋和桁架钢筋。桁架钢筋包括向上凸起呈弧形的上弦杆和下弦杆，上弦杆与两个下弦杆平行设置。桁架钢筋的上方设置有若干个反力梁，反力梁上设置有与桁架钢筋一一对应的压力梁，压力梁与桁架钢筋平行设置，反力梁的两端设置有拉杆，位于反力梁同一端的相邻的拉杆之间设置有花篮螺栓和应力计，拉杆的底端与模台连接。本发明还公开了一种预应力桁架钢筋叠合板的生产方法。本发明采用上述预应力桁架钢筋叠合板及其生产方法，使桁架钢筋的力学性能得到充分发挥，能够解决现有的桁架钢筋叠合板的起拱及挠度问题，同时也提高了叠合板的抗弯性能。
