[0006] As a preferred embodiment, a steel ruler is provided on the top of the support plate in the horizontal direction, so as to accurately adjust the position of the positioning module.

[0007] As a preferred embodiment, a level bubble is fixed on the top of the support plate.

[0008] As a preferred embodiment, an upwardly tilted avoidance edge is provided at one end of the sliding shoe plate away from the positioning module, which can facilitate the bottom of the sliding shoe plate to slide along the top of the top plate steel bar binding frame.

[0009] As a preferred embodiment, a push handle is fixed on the top of the support plate.

[0010] As a preferred embodiment, a locking plate is fixed to the outer bottom of the bracket, and a locking bolt is provided on the locking plate to prevent the device from sliding when the shear reinforcement is welded.

[0011] As a preferred embodiment, two parallel T-shaped grooves are provided on the rear side wall of the support plate, a slider is provided in the T-shaped groove, a mounting bolt is fixed to the outer end of the slider, a mounting flange is fixed on the inner outer wall of the positioning module, a mounting flange is provided with a mounting hole for the mounting bolt to pass through, and a locking nut is installed on the mounting bolt, so that the position of the positioning module can be easily adjusted to adapt to the positioning of various shear reinforcements, and the positioning module can be removed and replaced to adapt to the installation of shear reinforcements of different shapes.

[0012] The utility model has the following beneficial effects:

[0013] The structure is simple and practical, the cost is low, and the transverse and longitudinal positions of the shear reinforcement of the precast beam and slab can be quickly and uniformly positioned, the installation line is guaranteed, and the installation quality of the shear reinforcement is improved.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with embodiments.

[0019] Embodiment 1, as Figures 1 to 3 As shown, the utility model is a sliding shoe type positioning device for installing shear reinforcement of prefabricated beams and slabs, comprising a support plate 8 arranged above a comb plate 9, a sliding shoe plate 3 is fixed to the bottom of the support plate 8, inner concave platforms are provided at the bottoms of both ends of the support plate 8, brackets 5 are fixed to the inner concave platforms, guide wheels 6 are rotatably mounted on the brackets 5, rolling grooves 7 cooperating with the top of the comb plate 9 are provided on the outer wall of the guide wheel 6, and a positioning module 2 is fixed to the rear side wall of the support plate 8.

[0020] During operation: place the guide wheel 6 on the comb plates 9 on both sides of the top plate steel bar binding frame, and then roll the guide wheel 6 on the top of the comb plate 9 along the length direction of the prefabricated beam. When the positioning module 2 on the support plate 8 moves to the position where the shear reinforcement needs to be arranged, the guide wheel 6 stops rolling, and the shear reinforcement is placed on the positioning module 2 for positioning. Then the lower part of the shear reinforcement can be welded to the longitudinal reinforcement of the top plate steel bar binding frame. After welding, continue to move the support plate to carry out the positioning and arrangement welding of the shear reinforcement at the next position.
