Description

Technical Field

[0001] This invention relates to the field of positioning fixture technology, specifically to a positioning fixture for prefabricated building composite slabs. Background Technology

[0002] Precast concrete composite slabs are a type of precast concrete composite floor slab. As one of the core components of precast concrete structures (PC structures), they consist of a "precast base slab" and a "cast-in-place concrete composite layer". They combine the industrial efficiency of precast components with the integrity of cast-in-place structures and are widely used in floor slab systems for residential buildings, office buildings, factories and other buildings.

[0003] In the prior art, when installing composite slabs, the composite slabs are lifted to a predetermined position using lifting equipment, and then laid out.

[0004] However, since the lifting equipment cannot accurately lift the composite slabs to a fixed position, the position of the composite slabs needs to be adjusted manually. Because the composite slabs are suspended, the adjustment process will cause the composite slabs to tilt, and the tilted composite slabs are not easy to splice accurately. Summary of the Invention

[0005] The purpose of this invention is to provide a positioning fixture for prefabricated building composite slabs to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning fixture for prefabricated building composite slabs, comprising: The lifting rope has a connecting rope at its bottom, which is connected to the lifting frame. A support rod is fixed to the surface of the lifting frame, and a support frame is fixed to the surface of the support rod. Ball bearings are installed inside the support frame, and a lower pressure cap is installed on the top of the ball bearings. A lifting rod is fixed to the surface of the lower pressure cap, and a rope is connected to the top of the lifting rod. A vertical pole is connected to the bottom of the ball bearings, and an extension rod and a hook are fixed to the bottom of the vertical pole.

[0007] Preferably, the top of the lifting rope is connected to the lifting equipment, the bottom of the lifting frame is placed on a composite plate, the surface of the composite plate is fixed with steel bars, the hook can be hung on the surface of the steel bars, and the composite plate moves with the hook, the upright and the extension rod.

[0008] Preferably, a handle is fixed to the surface of the lifting frame, and an elastic rod is fixed to the surface of the handle. Two sets of elastic rods are provided, and the elastic rods are elastic. The two sets of elastic rods are symmetrically fixed to the surface of the handle.

[0009] Preferably, the surface of the support frame is provided with a rolling groove, and a ball is provided in the rolling groove. The ball can roll in the rolling groove. When the ball rolls, the upright, hook and extension rod swing with the ball, and the composite plate swings with the hook, upright and extension rod. The surface of the ball is provided with a concave hole, and multiple sets of concave holes are provided, which are evenly distributed on the surface of the ball.

[0010] Preferably, the surface of the support rod is provided with a through groove, and a rope is inserted into the through groove, allowing the rope to move within the through groove.

[0011] Preferably, an arc-shaped rod is fixed to the surface of the support rod, and multiple sets of arc-shaped rods are provided. A limit tube is fixed to the other end of the arc-shaped rod, a force-bearing rod is fixed to the surface of the arc-shaped rod, and an arc-shaped tube is fixed to the top of the force-bearing rod. A rope is inserted into the inside of the arc-shaped tube, and the rope can move inside the arc-shaped tube.

[0012] Preferably, a lifting rod is inserted inside the limiting tube. The lifting rod can move up and down within the limiting tube. A lower pressure cover is fixed to the bottom of the lifting rod. The lower pressure cover moves up and down with the lifting rod. A protrusion is provided on the bottom surface of the lower pressure cover. The protrusion can be locked in a concave hole. After the lower pressure cover descends, the protrusion on the surface of the lower pressure cover is locked in the concave hole on the surface of the ball. The ball can no longer roll in the rolling groove, so that the ball remains stable. The hook, upright and extension rod connected to the bottom of the ball remain stable, and the overlapping plate at the bottom of the hook remains stable.

[0013] Preferably, a limiting plate is fixed to the top of the lifting rod. The limiting plate moves up and down with the lifting rod. A spring is connected to the surface of the limiting plate, and the other end of the spring is connected to the surface of the limiting tube. The spring exerts a pushing force on the limiting plate, causing the limiting plate to move away from the surface of the limiting tube.

[0014] Preferably, the end of the rope is connected to the surface of the limiting plate, the limiting plate moves with the rope, and multiple sets of ropes are provided, with multiple sets of ropes connected to the surface of the limiting plate.

[0015] Preferably, one end of the rope extends from the surface of the lifting frame, and the rope can move inside the support rod and the arc-shaped tube. Pulling the exposed end of the rope on the surface of the lifting frame causes the other end of the rope to rise. The rope pulls the limiting plate, causing the lifting rod to rise from inside the limiting tube. The exposed end of the rope on the surface of the lifting frame can be locked between two sets of elastic rods. The elastic rods are elastic, and the two sets of elastic rods clamp the surface of the rope, stabilizing the end of the rope.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The present invention proposes a method where a rope is manually pulled, which pulls up a limiting plate, causing the limiting plate and lifting rod to rise. The spring on the surface of the limiting plate is stretched, and the lifting rod drives the lower pressure cover to rise. The lower pressure cover no longer presses against the surface of the ball bearings, allowing the ball bearings to roll in the rolling groove. Under the action of gravity, the composite plate is brought into a horizontal state. The composite plate is then lowered by a lifting device, allowing the composite plate to be accurately spliced.

It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 7 The present invention provides a technical solution: Example 1: A positioning fixture for prefabricated building composite slabs, comprising: a lifting rope 2, a connecting rope 3 at the bottom of the lifting rope 2, a lifting frame 1 connected to the bottom of the connecting rope 3, a support rod 12 fixed to the surface of the lifting frame 1, a support frame 13 fixed to the surface of the support rod 12, a ball bearing 20 inside the support frame 13, a lower pressure cover 18 at the top of the ball bearing 20, a lifting rod 24 fixed to the surface of the lower pressure cover 18, a rope 11 connected to the top of the lifting rod 24, a vertical rod 7 connected to the bottom of the ball bearing 20, an extension rod 8 and a hook 6 fixed to the bottom of the vertical rod 7, a through groove 17 on the surface of the support rod 12, and a rope 11 inserted into the through groove 17. The support rod 12 is able to move within the through groove 17. An arc-shaped rod 16 is fixed to the surface of the support rod 12. Multiple sets of arc-shaped rods 16 are provided. A limit tube 25 is fixed to the other end of the arc-shaped rod 16. A force-bearing rod 15 is fixed to the surface of the arc-shaped rod 16. An arc-shaped tube 14 is fixed to the top of the force-bearing rod 15. A rope 11 is inserted into the inside of the arc-shaped tube 14. The rope 11 can move inside the arc-shaped tube 14. The protrusion on the surface of the lower pressure cover 18 is locked in the concave hole 19 to keep the ball 20 stable, so that the composite plate 4 is stable at the bottom of the lifting frame 1. When the rope 11 is not in use, it can be locked between the elastic rods 10 to prevent tangling. A handle 9 is provided on the surface of the lifting frame 1 so that the lifting frame 1 can be pulled.

[0027] Example 2: Based on Example 1, the top of the lifting rope 2 is connected to the lifting equipment, and the bottom of the lifting frame 1 is placed on the composite plate 4. The surface of the composite plate 4 is fixed with steel bars 5, and the hook 6 can be hung on the surface of the steel bars 5. The composite plate 4 moves with the hook 6, the upright 7 and the extension rod 8. The hook 6 at the bottom of the extension rod 8 is hung on the surface of the steel bars 5 on the surface of the composite plate 4. The composite plate 4 rises with the extension rod 8. The lifting equipment is connected to the lifting frame 1 through the lifting rope 2 and the connecting rope 3 to lift the lifting frame 1. When the lifting frame 1 moves above the area where the composite plate 4 needs to be laid, the rope 11 is pulled manually. After the rope 11 is pulled, the rope 11 pulls up the limiting plate 22, so that the limiting plate 22 and the lifting rod 24 rise.

[0028] A handle 9 is fixed to the surface of the lifting frame 1, and an elastic rod 10 is fixed to the surface of the handle 9. There are two sets of elastic rods 10. The elastic rods 10 are elastic. The two sets of elastic rods 10 are symmetrically fixed to the surface of the handle 9. The protrusion on the surface of the lower pressure cover 18 is stuck in the concave hole 19 to keep the ball 20 stable, so that the stacked plate 4 is stable at the bottom of the lifting frame 1. When the rope 11 is not in use, it can be stuck between the elastic rods 10 to prevent tangling. The lifting frame 1 is provided with a handle 9, which can be used to pull the lifting frame 1.

[0029] The support frame 13 has a rolling groove 21 on its surface, and a ball bearing 20 is disposed in the rolling groove 21. The ball bearing 20 can roll in the rolling groove 21. When the ball bearing 20 rolls, the upright 7, hook 6, and extension rod 8 swing with the ball bearing 20, and the stacked plate 4 swings with the hook 6, upright 7, and extension rod 8. The surface of the ball bearing 20 has recessed holes 19, and multiple sets of recessed holes 19 are evenly distributed on the surface of the ball bearing 20. A lifting rod 24 is inserted into the limiting tube 25, and the lifting rod 24 can limit the movement of the ball bearing 20. The lifting rod 24 moves vertically within the pipe 25. A lower pressure cover 18 is fixed to the bottom of the lifting rod 24. The lower pressure cover 18 moves vertically along with the lifting rod 24. A protrusion is provided on the bottom surface of the lower pressure cover 18, which can be engaged in a recessed hole 19. After the lower pressure cover 18 descends, the protrusion on the surface of the lower pressure cover 18 engages in the recessed hole 19 on the surface of the ball bearing 20, preventing the ball bearing 20 from rolling in the rolling groove 21, thus stabilizing the ball bearing 20. The hook 6, upright 7, and extension rod 8 connected to the bottom of the ball bearing 20 remain stable. The overlapping plate 4 at the bottom of the hook 6 ensures stability. To maintain stability, a limit plate 22 is fixed to the top of the lifting rod 24. The limit plate 22 moves up and down with the lifting rod 24. A spring 23 is connected to the surface of the limit plate 22, and the other end of the spring 23 is connected to the surface of the limit tube 25. The spring 23 exerts a pushing force on the limit plate 22, causing the limit plate 22 to move away from the surface of the limit tube 25. The end of the rope 11 is connected to the surface of the limit plate 22, and the limit plate 22 moves with the rope 11. Multiple sets of ropes 11 are provided, and multiple sets of ropes 11 are connected to the surface of the limit plate 22. One end of rope 11 extends from the surface of the lifting frame 1. Rope 11 can move inside the support rod 12 and the arc tube 14. Pulling the exposed end of rope 11 on the surface of the lifting frame 1, the other end of rope 11 rises. Rope 11 pulls the limiting plate 22, causing the lifting rod 24 to rise from inside the limiting tube 25. The exposed end of rope 11 on the surface of the lifting frame 1 can be locked between two sets of elastic rods 10. The elastic rods 10 are elastic. The two sets of elastic rods 10 clamp the surface of rope 11, stabilizing the end of rope 11.

[0030] The hook 6 at the bottom of the extension rod 8 is attached to the surface of the reinforcing steel 5 on the surface of the composite slab 4. The composite slab 4 rises with the extension rod 8. The lifting equipment is connected to the lifting frame 1 through the lifting rope 2 and the connecting rope 3. The lifting frame 1 is lifted. When the lifting frame 1 is moved above the composite slab 4 to be laid, the rope 11 is pulled manually. After the rope 11 is pulled, the rope 11 pulls up the limiting plate 22, causing the limiting plate 22 and the lifting rod 24 to rise. The spring 23 on the surface of the limiting plate 22 is stretched. The lifting rod 24 drives the lower pressure cover 18 to rise. The lower pressure cover 18 is no longer pressed against the surface of the ball bearing 20, allowing the ball bearing 20 to roll in the rolling groove 21. Under the action of gravity, the composite slab 4... When the composite plate 4 is in a horizontal position, it is lowered by the lifting equipment, and the composite plate 4 can be accurately spliced. When the composite plate 4 is lifted, the spring 23 pulls the limiting plate 22, which causes the lifting rod 24 to drive the lower pressure cover 18 to descend. The lower pressure cover 18 is held against the surface of the ball bearing 20. The surface of the ball bearing 20 is provided with a concave hole 19, and the surface of the lower pressure cover 18 is provided with a protrusion. The protrusion on the surface of the lower pressure cover 18 is stuck in the concave hole 19 to keep the ball bearing 20 stable, so that the composite plate 4 is stable at the bottom of the lifting frame 1. When the rope 11 is not in use, it can be locked between the elastic rods 10 to prevent entanglement. The surface of the lifting frame 1 is provided with a handle 9, which can be pulled.
