Detachable bottom formwork type steel bar truss deck
The invention discloses a detachable bottom formwork type steel bar truss deck. The deck comprises a bottom formwork and multiple steel bar trusses, wherein each steel bar truss is connected with the bottom formwork through multiple connecting buckles located in one row respectively; a rectangular groove is formed in the upper part of each connecting buckle, clamping grooves are correspondingly formed in side surfaces of the rectangular groove, two lower chord steel bars of each steel bar truss are clamped in the two clamping grooves of the corresponding connecting buckle respectively, and the connecting buckle is fixedly connected with the bottom formwork through fasteners. Two clamping grooves are correspondingly formed in each connecting buckle, the two lower chord steel bars of each steel bar truss are clamped in the two clamping grooves of the same connecting buckle, under the effect of gravity of concrete, although the two lower chord steel bars form two thrust forces having the same magnitude and opposite directions, the two thrust forces which have the same magnitude and the opposite directions and act on the connecting buckle are offset mutually, thus, tensile deformation of the bottom formwork due to the fact that the two thrust forces are transferred to the bottom formwork through the connecting buckle can be avoided, and difficulty in subsequent detachment due to the fact that the fasteners connecting the bottom formwork and the connecting buckle bear shearing forces can be avoided.
