the bottom of the rectangular vertical plate is provided with a vertical groove, and the bottom of the rectangular vertical plate is sleeved outside the limiting frame.
Further, the simulation part comprises a plurality of sleeves arranged in a matrix.
Furthermore, the dislocation distance of the notches of the pair of side dies is larger than or equal to the width of the notch.
The utility model has the advantages that: the sleeve is adopted to simulate the position of the shear nail, and the sleeve is avoided by adjusting the reinforcing steel bars, so that the problem of conflict when the shear nail on the laminated slab is connected with the shear nail on the steel beam is effectively solved, and the shear nail is smoothly inserted into the shear groove of the laminated slab.
Because the staggered notches are adopted, the two ends of the steel bars are not on the same horizontal line, the problem that annular steel bars are exposed to conflict when the laminated slabs are butted is effectively solved, and the laminated slabs are smoothly butted.
