Prefabricated tensioning safety platform for prestressed steel box concrete cover beam
The invention discloses an assembly type tensioning safety platform for a prestressed steel box concrete cover beam. The upper longitudinal beam is arranged on the upper cross beam, the upper longitudinal beam and the upper cross beam are provided with screw holes at different intervals, the upper longitudinal beam and the upper cross beam are connected through screws, and the screw holes at different intervals are arranged, so that the interference effect of a capping beam top pad stone on the arrangement of the upper cross beam is avoided; the lower longitudinal beams are arranged and welded on the lower cross beams according to a certain interval and serve as a steel plate net support, and the slidable reverse buckling devices are fixed on the upper cross beams and reversely buckled on a steel cover beam top plate through U-shaped buckles and screws. The platform solves the problem that constructors do not have an operation platform in the construction procedures of pulling out steel pipes, pulling steel strands, tensioning prestress, releasing and the like of the prestressed steel box concrete cover beam. The adjustable component of the platform can adapt to cover beam structure forms with different widths and heights, the slidable reverse buckling device is fixed to the top of the cover beam, no welding is needed, and damage to the cover beam structure caused by a large amount of welding and dismantling is avoided.
本发明公开了一种预应力钢箱混凝土盖梁装配式张拉安全平台；上纵梁布置于上横梁上，上纵梁与上横梁开设不同间距螺杆孔，通过螺杆进行连接，设置不同间距的螺杆孔，解决盖梁顶垫石对上横梁布置产生的干扰作用，下横梁与伸缩竖杆进行连接，作用于上纵梁上，下纵梁按照一定间距布置焊接于下横梁上，作为钢板网支撑，可滑移反扣装置固定于上横梁上，通过U型扣与螺杆反扣于钢盖梁顶板上。本平台解决了预应力钢箱混凝土盖梁在钢管拔出、钢绞线穿束、预应力张拉、放张等施工工序，施工人员无操作平台等问题。此平台可调节构件可适应不同宽度、高度盖梁结构形式，可滑移反扣装置固定于盖梁顶部，无需任何焊接，避免大量焊接及拆除对盖梁结构本身产生破坏。
