[0035] A number of dowel holes 2, vibrating holes 3 and oval reserved holes 7 for positioning screws are provided on the positioning steel plate 1.

[0036] Preferably, the present invention further provides a method for positioning the transfer layer steel bars, wherein a transfer layer steel bar positioning device is used to position the transfer layer steel bars, and the positioning method comprises:

[0037] Step 1: First, the processing plant makes the positioning steel plate 1 according to the drawing, and drills the reinforcement holes 2 and the elliptical reserved holes 7 for the positioning screw rod according to the designed position of the transfer layer reinforcement, and reserves the vibration hole 3 on the positioning steel plate 1;

[0038] Step 2: Insert the dowel 4 through the dowel hole 2 on the positioning steel plate 1, and then adjust the position of the positioning steel plate 1 and the dowel 4 according to the positioning line on the floor slab;

[0039] Step 3: Connect the dowel 4 and the horizontal ladder bar 5 through the dowel mouth fastener 6;

[0040] Step 4: Spot weld one end of the positioning steel plate fixing bracket 9 to the positioning steel plate 1, and connect the other end of the positioning steel plate fixing bracket 9 to the steel bar positioning device.

[0041] The working principle and beneficial effects of the above technical solution are as follows: First, the processing plant produces the positioning steel plate 1 according to the drawings, drills the dowel holes 2 according to the designed position of the transfer layer dowels, and opens the vibrating holes 3 on the positioning steel plate 1. The dowels 4 are inserted through the dowel holes 2 on the positioning steel plate 1, and the positions of the positioning steel plate 1 and the dowels 4 are adjusted according to the positioning line on the floor slab. The horizontal ladder bars 5 and the dowels 4 are fixed with dowel mouth fasteners 6. The horizontal ladder bar vertical positioning screw 8 positions and fixes the horizontal ladder bar 5. The horizontal ladder bar vertical positioning screw 9 is positioned and released according to the building outline and axis. One end of the positioning steel plate fixing bracket 9 is inserted into the positioning device for fixing, and the other end of the positioning steel plate fixing bracket 9 is spot welded to the outer wall of the positioning steel plate 1. As a result, the positioning steel plate 1, the inserted reinforcement 4, and the horizontal ladder reinforcement 5 form a whole through the positioning steel plate 1, ensuring that the inserted reinforcement does not shift during the concrete construction process, thereby ensuring the accurate positioning of the transfer layer reinforcement. Among them, the positioning steel plate 1 is 20mm away from the cast-in-place concrete floor surface, and the horizontal ladder reinforcement 5 is 80-100mm away from the upper surface of the positioning steel plate. The setting of the positioning device ensures that the positioning steel plate 1, the inserted reinforcement 4 and the horizontal ladder reinforcement 5 do not shift during the concrete pouring process, thereby ensuring the accurate positioning of the transfer layer reinforcement.

[0042] It should be noted that according to the in-depth design of the prefabricated shear wall panel dowel arrangement diagram, the dowel hole 2 is accurately located on the positioning steel plate 1, and the dowel 4 is inserted into the positioning hole 2. According to the position of the reserved water and electricity pipelines in the shear wall and the operating position of the vibrating rod, a vibration hole 3 is opened on the positioning steel plate, and an elliptical positioning screw and an elliptical reserved hole 7 are opened at appropriate positions at both ends of the positioning steel plate to fix the vertical positioning screw 8 of the horizontal ladder reinforcement with a diameter of 14mm. The positioning steel plate 1 is fixed to the composite plate through the positioning steel plate fixing bracket 9. According to the wall dowel positioning diagram, the horizontal ladder reinforcement 5 is made, and two short screws with a diameter of 14mm are horizontally welded as bolts at the position where the horizontal ladder reinforcement 5 fixes the dowel 4. The net distance between the bolts is the longitudinal steel bar diameter + 2mm, and steel bars with the same diameter as the horizontal ladder reinforcement 5 are used as dowel mouth fasteners 6. The net distance of the dowel mouth fasteners 6 is 16mm. When in use, place the positioning steel bar in the short screw rod inside the horizontal ladder bar 5 and fix it with nuts and fasteners. After the positioning steel plate 1 is temporarily laid out in place, use bolts to fix the positioning steel plate 1 and the embedded parts in the appropriate position with the composite plate through the vertical positioning screw rod 8 of the horizontal ladder bar. The height of the embedded parts is the same height (thickness) as the cast-in-place concrete. Then install the positioning device on the positioning steel plate fixing bracket 9, and accurately position the positioning steel plate 1 by adjusting the positioning device.

[0048] Preferably, the rotating shaft 27 movably passes through the through hole 2 17 and the through hole 4 25, and movably connects the steel bar fixing seat 23 with the support seat 10.

A plurality of return springs 141 are fixedly connected between the positioning arm 14 and the outer wall of the inner shell 11. One end of the positioning arm 14 close to the fixed block 15 is fixedly connected to the curved connecting rod 30, and the intersection of the positioning arm 14 and the curved connecting rod 30 is rotatably connected to the fixed block 15. The end of the curved connecting rod 30 close to the inclined plate 31 abuts against the inclined plate 31, and the inclined plate 31 is fixedly connected to the outer wall of the first connecting rod 32. The end of the first connecting rod 32 close to the inner shell 11 can move through the inner shell 11. The end of the first connecting rod 32 extending into the inner shell 11 is fixedly connected to the third connecting plate 34, and a connecting spring 33 is sleeved on the outer wall of the first connecting rod 32.

[0054] Preferably, the third connecting plate 34 is slidably connected to the inner wall of the inner shell 11, one end of the connecting spring 1 33 is fixedly connected to the third connecting plate 34, and the other end of the connecting spring 1 33 is fixedly connected to the inner wall of the inner shell 11. A limiting slide groove 35 is provided on the inner wall of the inner shell 11, and both ends of the support plate 37 extend into the limiting slide groove 35 and are slidably connected to the limiting slide groove 35. A connecting spring 2 36 is fixedly connected between the third connecting plate 34 and the support plate 37. One end of the positioning steel plate fixing bracket 9 extends into the inner shell 11 and abuts against the support plate 37. The locking assembly 13 is fixedly connected to the inner wall of the inner shell 11, and the locking assembly 13 is located at the entrance of the inner shell 11.

[0055] Preferably, the locking assembly 13 includes: a fixed base plate 38 and a rotating ring 43, the fixed base plate 38 is fixedly connected to the inner wall of the inner shell 11, the electric telescopic rod 40 is fixedly connected to the fixed base plate 38 through the fixed block 2 39, the output end of the electric telescopic rod 40 extends into the connecting sleeve 41 and is fixedly connected to the inner wall of the connecting sleeve 41, the connecting sleeve 41 is fixedly connected to the rotating ring 43 through the fixed rod 1 42, and a plurality of limiting arc grooves 44 are opened on the rotating ring 43 at equal intervals, and a plurality of arc-shaped holding plates 46 are movably distributed in a ring array between the fixed base plate 38 and the rotating ring 43, and each arc-shaped holding plate 46 is movably connected along the limiting arc groove 44 through the positioning rod 45.

[0056] Preferably, a through hole 47 for passing the positioning steel plate fixing bracket 9 is provided in the center of the fixed base plate 38, and each arc-shaped holding plate 46 is provided with an arc-shaped end face matching the outer wall of the positioning steel plate fixing bracket 9 on the side close to the positioning steel plate fixing bracket 9. After several arc-shaped end faces are closed, a circle matching the outer wall of the positioning steel plate fixing bracket 9 is formed. The side where every two arc-shaped holding plates 46 are close to each other is an outer arc surface and an inner arc surface that match each other, and the outer arc surface slides along the inner arc surface.

[0057] The working principle and beneficial effects of the above technical solution are as follows: when in use, the operator adjusts the rotation angle of the steel bar fixing seat 23 to the same angle as the positioning steel plate fixing bracket 9, and then inserts the positioning steel plate fixing bracket 9 into the inner shell 11 and abuts against the support plate 37, so that the support plate 37 is pushed along the limiting slide groove 35 toward the third connecting plate 34. At this time, the connecting spring 2 36 is compressed and pushes the first connecting rod 32 through the third connecting plate 34 until the first connecting rod 32 abuts against the inner wall of the outer shell 103, so that the inclined plate 31 is at the first connecting rod 32. Driven by the two sets of curved links 30, they move in the same direction and push the curved connecting rod 30 in the direction away from the first connecting rod 32. At this time, the two sets of curved connecting rods 30 rotate around the fixed block 15 in the direction of approaching each other. Driven by the two sets of curved connecting rods 30, the two sets of positioning arms 14 penetrate the inner shell 11 and abut against the outer wall of the positioning steel plate fixing bracket 9. The reset spring 141 compresses and accumulates dynamic potential energy for resetting the positioning arm 14 after the positioning steel plate fixing bracket 9 is pulled out, so that the positioning steel plate fixing bracket 9 will not shake after entering the inner shell 11, and plays an anchoring role.

[0058] At the same time, when the positioning steel plate fixing bracket 9 pushes the support plate 37 and the third connecting plate 34 to abut the first connecting rod 32 against the inner wall of the shell 103, the electric telescopic rod 40 is started and pushes the connecting sleeve 41 to move, wherein the distance that the connecting sleeve 41 can move is the maximum length of the limiting arc groove 44 (that is, the maximum telescopic distance of the electric telescopic rod 40 is the maximum length of the limiting arc groove 44), thereby pushing the rotating circle 43 to rotate through the connecting sleeve 41 and the fixing rod 42. At this time, several groups of positioning rods 45 slide in the limiting arc groove 44. The plurality of arc-shaped holding plates 46 are moved and driven to rotate, so that the arc-shaped end surfaces of the plurality of arc-shaped holding plates 46 are completely fitted with the outer wall of the positioning steel plate fixing bracket 9, and the positioning steel plate fixing bracket 9 is tightly embraced. Among them, the side where each two arc-shaped holding plates 46 are close to each other is the outer arc surface and the inner arc surface that match each other. The setting of the outer arc surface and the inner arc surface ensures the smoothness of the two arc-shaped holding plates 46 when rotating and reduces the friction. At this point, a group of steel bar fixing seats 23 tightly fixes a positioning steel plate fixing bracket 9.

[0059] Through the above method, several positioning steel plate fixing brackets 9 can be inserted one by one into the corresponding steel bar fixing seats 23 for tight positioning, thereby facilitating the accurate fixation of the positioning steel plate fixing brackets 9 and the horizontal ladder bars 5 for the inserted bars 4, thereby ensuring that the inserted bars 4 do not shift during the concrete pouring process, thereby ensuring the accurate positioning of the transition layer steel bars.

[0066] Step 1: The controller calculates the meshing deformation coefficient between the arc gear ring 26 and the driving gear 1 29 when the steel bar fixing seat 23 rotates based on the detection values ​​of the force sensor and the angle sensor and formula (1):

[0068] Wherein, Y is the meshing deformation coefficient between the arc gear ring 26 and the driving gear 29 when the steel bar fixing seat 23 rotates, F1 is the detection value of the force sensor, F2 is the maximum pressure that the preset steel bar fixing seat 23 can withstand, θ1 is the pressure angle of the arc gear ring 26, θ2 is the pressure angle of the driving gear 29, θ3 is the detection value of the angle sensor, μ is the friction coefficient between the arc gear ring 26 and the bevel gear 2 19, z1 is the number of teeth of the arc gear ring 26, z2 is the number of teeth of the driving gear 29, h1 is the tooth addendum coefficient of the arc gear ring 26, h2 is the tooth addendum coefficient of the driving gear 29, K is the stability coefficient (the value is greater than 0 and less than 1, which is set to consider the stability factor of the internal structure installation of the arc gear ring 26 and the driving gear 29), e is a natural constant with a value of 2.72, sin is sine, and cos is cosine;

[0069] Step 2: The controller compares the meshing deformation coefficient between the arc-shaped ring gear 26 and the driving gear 29 with the preset meshing deformation coefficient. If the meshing deformation coefficient between the arc-shaped ring gear 26 and the driving gear 29 is greater than the preset meshing deformation coefficient (1.0), the controller controls the alarm to sound an alarm.

[0070] The working principle and beneficial effects of the above scheme are as follows: as the number of rotations and the use time of the steel bar fixing seat 23 increase, the wear of the arc gear ring 26 and the driving gear 29 also increases. The force sensor and the angle sensor are used to detect the pressure on the steel bar fixing seat 23 during the rotation process. The controller uses formula (1) to calculate the meshing deformation coefficient between the arc gear ring 26 and the driving gear 29. If the meshing deformation coefficient between the arc gear ring 26 and the driving gear 29 is greater than the preset meshing deformation coefficient, the preset meshing deformation coefficient is 1.0, the controller controls the alarm to sound an alarm to notify the relevant staff to inspect the steel bar fixing seat 23, thereby increasing the intelligence of the positioning device.
