Description
Technical Field
The utility model relates to a building engineering technical field especially relates to a temporary reinforcement device of prefabricated superimposed sheet hoist and mount in-process.
Background
With the national emphasis on energy conservation and emission reduction of building engineering, the assembly type building is more and more widely applied. For the main structure, the application of the prefabricated floor slab is the most extensive. The traditional precast floor slab mainly adopts a concrete steel bar truss laminated slab, and the steel bar truss can improve the rigidity of the precast slab in the direction of a truss rib, so that the cracking of the slab bottom in the production, transportation and hoisting construction processes is avoided. However, in the direction perpendicular to the truss ribs, because only the precast slabs resist bending, when the laminated slab is wider, the slab bottom is easy to crack, which affects the structural safety.
Therefore, the present invention provides a simple temporary reinforcing apparatus for a prefabricated panel, which can improve the bending resistance of the prefabricated panel in the width direction.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a temporary reinforcement device of prefabricated superimposed sheet hoist and mount in-process to solve above-mentioned technical problem.
In order to achieve the purpose, the temporary reinforcing device in the hoisting process of the prefabricated composite slab comprises a concrete steel bar truss composite slab and a steel pipe,
the concrete steel bar truss composite slab comprises a concrete precast slab and a plurality of steel bar trusses; the plurality of steel bar trusses are arranged in parallel along the length direction of the concrete precast slab;
the steel bar truss comprises an upper chord steel bar and two lower chord steel bars; the lower chord steel bars are embedded into the concrete precast slabs along the length direction of the concrete precast slabs; the upper chord steel bars are arranged above the concrete precast slabs along the length direction of the concrete precast slabs; each lower chord steel bar is connected with the upper chord steel bar through a wave-shaped bent steel bar;
clamping pieces are inserted below the upper chord steel bars of each steel bar truss; the steel pipe is fixed on the clamping piece through a U-shaped bolt and a nut and is arranged along the width direction of the concrete precast slab.
Preferably, each bending point of the bent reinforcing bars is connected with the upper chord reinforcing bars.
Preferably, the clamping piece is arranged between two adjacent bending points of the bent reinforcing steel bar.
Has the advantages that: the temporary reinforcing device in the hoisting process of the prefabricated laminated slab can improve the rigidity of the concrete prefabricated slab in the width direction and avoid cracking of a floor slab during hoisting; the device can be disassembled after being installed, and is convenient to recycle.
