as shown in fig. 1 to 4, a quick flattening tool for hollow slab beam hinge joint reinforcing steel bars comprises a lever 1 and a support rod 2, wherein one end of the lever 1 is provided with an upper limiting clamping strip 13, the upper limiting clamping strip 13 is vertically fixed with the lever 1, and a connecting block 12 is arranged between the upper limiting clamping strip 13 and the lever 1. And the upper limiting clamping strip 13 and the connecting block 12 are short steel bars, and one end of the connecting block extends out of the end part of the lever 1. Because there may be the difference in the position of pre-buried door shape muscle on the hollow slab beam of different dimensions, so when lever itself is far away from pre-buried door shape muscle, need compensate the problem of length deviation through setting up the connecting block.

The one end that is close to upper limit card strip 13 on the lever 1 still is equipped with U-shaped ear 11, and two U-shaped ears 11 are fixed respectively in the both sides of lever 1, U-shaped ear 11 sets up 1/4 department at lever 1 length, and the U-shaped ear is formed by C12 reinforcing bar bending. The top of bracing piece 2 is fixed with spacing horizontal pole 21 perpendicularly welded, the U-shaped ear of both sides is worn out respectively at the both ends of spacing horizontal pole 21, the lower part of bracing piece 2 is equipped with down spacing card strip 22. The lever is movably connected with the supporting rod and is limited by the U-shaped lugs, so that the front position and the rear position of the supporting rod are convenient to adjust, and the lever on the upper portion is convenient to apply force more easily.

The lower limiting clamping strip 22 is welded with the supporting rod 2 in parallel, and the lower end of the lower limiting clamping strip 22 exceeds the lower end of the supporting rod 2. The lever 1 is a steel pipe, the supporting rod 2 is a C25 steel bar, and the limiting cross rod 21, the upper limiting clamping strip 13 and the lower limiting clamping strip 22 are all C12 steel bars.

To sum up, the tool is designed according to the lever principle, the lever is made of a phi 48X 1000mm steel pipe, the supporting rod is made of C25X 800mm steel bars, C12 steel bars are welded on two sides of the supporting point of the steel pipe to form U-shaped lugs, C12 steel bars are penetrated in the U-shaped lugs and then welded with the top of the supporting rod to form a T-shaped hinge structure, and short steel bar limiting clamps are welded at the front end of the lever and the bottom of the supporting rod. When the tool is used, the supporting rod is clamped at the top of the embedded hinge joint rib, the front end of the lever extends into the embedded portal rib of the beam surface, the tail of the lever is slowly pressed down to bend the hinge joint portal rib in place at one time, the construction quality is improved, and the construction efficiency is improved.

Compared with the traditional process, the utility model has the advantages that the traditional hinge joint reinforcing steel bar is flattened, and the local deformation of the hinge joint reinforcing steel bar is easily caused because constructors repeatedly beat the hinge joint reinforcing steel bar, and the uneven height of the flattened reinforcing steel bar influences the subsequent reinforcement binding, increases the rework cost and influences the construction progress; and the utility model discloses both use manpower sparingly, financial resources, can reduce the damage that causes the reinforcing bar again, promote the flat curved precision, this instrument is simple and practical, and the cost of labor and improvement work efficiency can be practiced thrift in the processing preparation of being convenient for.
