[0020] like Figure 2 , Figure 3 As shown, the locking member 4 includes a connecting rod 41, a pair of locking rods 42 and a locking head 43. The locking rods 42 are arranged at both ends of the connecting rod 41, and the side wall of the positioning plate 1 is provided with a locking hole 44 for the locking rod 42 to be inserted. The locking head 43 is arranged at the end position of the locking rod 42 in an umbrella shape, and a locking groove for the locking head 43 to be embedded is provided in the locking hole 44.

[0021] like Figure 2 , Figure 3 As shown, the support legs 2 are vertically arranged on the lower end surfaces of both ends of the positioning plate 1 , and the support legs 2 include a support tube 21 , a support rod 22 , a support frame 23 and a fixing member 5 .

[0022] like Figure 2 , Figure 3As shown, the support tube 21 is vertically arranged, the support rod 22 is vertically slidably connected to the support tube 21, and the upper end is fixed to the positioning plate 1, the support frame 23 is arranged on both sides of the support tube 21, and the support tube 21 is propped up, and the lower end of the support frame 23 is provided with a concrete pad 24 to avoid leakage of reinforcement after pouring.

[0023] like Figure 2 , Figure 3 As shown, the fixing member 5 is disposed on the supporting tube 21 and is used to fix the supporting rod 22 . The fixing member 5 includes a fixing plate 51 and a fixing block 52 .

[0024] like Figure 2 , Figure 3 As shown, the fixing plate 51 is horizontally slidably connected to the support tube 21, and the end surface of the fixing plate 51 is concave. The fixing block 52 is arranged on the inner side of the fixing plate 51, and the side wall of the support rod 22 is vertically provided with a vertical groove 53 for the fixing block 52 to slide, and a transverse groove 54 connected to the side wall of the vertical groove 53 and for the fixing block 52 to slide and insert, and the fixing block 52 and the transverse groove 54 are interference fit.

[0025] When it is necessary to lay a steel bar frame in the formwork, each mounting plate is taken out, and then the height of the support leg 2 is adjusted according to the height requirement of the bottom layer of steel bars. During the adjustment, the support tube 21 is controlled to slide along the outer wall of the support rod 22, and the fixed block 52 slides in the vertical groove 53.

[0026] When the height of the support leg 2 meets the requirement, the fixing plate 51 is controlled to drive the fixing block 52 to slide horizontally, so that the fixing block 52 slides into the transverse groove 54, and the fixing block 52 is clamped under interference fit to complete the clamping and fixing between the support tube 21 and the support rod 22, thereby realizing the adjustment of the height position of the positioning plate 1.

[0027] Then, the positioning plates 1 are arranged one by one in a straight line, and the adjacent positioning plates 1 are connected with each other by the cooperation of the plug block 11 and the slot 12 on the positioning plate 1. Then, the locking member 4 is taken out, and the locking rod 42 is inserted into the locking hole 44 at the end of the positioning plate 1, and the connecting rod 41 is pressed hard to make the locking head 43 snap into the locking groove, thereby completing the locking between the adjacent positioning plates 1.

[0028] Then, the bottom layer of steel bars are passed through the mounting holes 3 on the positioning plate 1 to achieve equal spacing and position limiting of the bottom layer of steel bars. Then, according to the above steps, the upper layer of the positioning plate 1 is arranged, and then the top layer of steel bars are passed through the mounting holes 3 to achieve equal spacing and position limiting, and finally the upper and lower layers of steel bars are tied and fixed to complete the layout of the steel frame. Finally, concrete is poured, and the positioning device is poured into the floor slab to complete the construction of the floor slab.

[0029] Therefore, by adopting a spliced ​​positioning plate 1, the positioning support of the steel bars is formed by staggering horizontally and vertically in the mold, and positioning holes for the steel bars to pass through are set in the positioning plate 1, so that the upper and lower layers of steel bars can be arranged at equal intervals, which can not only meet the precise positioning of the steel bars, but also realize the rapid arrangement of the steel bars, thereby improving the construction efficiency and ensuring the quality and safety of the building.

[0030] At the same time, by setting a height-adjustable and conveniently adjustable support leg 2, the support leg 2 can adapt to the use requirements of different heights, meet the precise positioning and rapid binding and fixing of the steel bars, make the use of the support device more convenient, and improve practicality.

[0031] Embodiment 2: like Figure 4 As shown, the positioning plate 1 includes a bottom plate 13 and a top plate 14, one end of the top plate 14 is rotatably connected to the top plate 14, and the other end is provided with a hook 15, and the bottom plate 13 is provided with a slot 16 for the hook 15 to be embedded. The bottom plate 13 and the top plate 14 are both provided with relatively aligned notches 17, and a pair of notches 17 are buckled to form a mounting hole 3 for the steel bar to pass through.

[0032] like Figure 4 As shown, the side wall of the bottom plate 13 is provided with an elastic fastening hook 18 , and the side wall of the top plate 14 is provided with a fastening rod 19 for the fastening hook 18 to hook.

[0033] After the positioning plate 1 is installed, the top plate 14 can be flipped open, and then the steel bar can be directly embedded in the notch 17, and then the top plate 14 can be controlled to flip to a horizontal state, so that the hook 15 can be embedded in the slot 16 to achieve the clamping and fixing between the top plate 14 and the bottom plate 13. At the same time, the top plate 14 is pressed to make the fastening hook 18 hook the fastening rod 19, thereby increasing the stability between the bottom plate 13 and the top plate 14 and achieving the fastening and fixing of the steel bar.
