Description

Technical Field

[0001] This utility model relates to the field of construction hoisting equipment technology, and in particular to a prefabricated composite slab construction hoisting equipment. Background Technology

[0002] Precast composite slabs are a building formwork system that combines precast and cast-in-place technologies, primarily used in high-rise and large-span buildings. They consist of a precast concrete base slab and a cast-in-place reinforced concrete layer, with galvanized steel mesh embedded in the middle. These layers are then welded to the steel truss via embedded joists to form an integrated structure. Suitable for high-rise buildings, large-span commercial spaces, and structures requiring high overall rigidity, precast composite slabs can replace traditional steel / aluminum / wood formwork, saving construction time and costs.

[0003] When constructing composite slabs, a crane is used to lift the slabs to the floor for installation. During this process, slings are used to secure the slabs, and then hooks on the crane are used to lift them. Workers are needed to assist with the installation, but some reinforcing steel bars are exposed at the edges of the slabs. Using slings to secure the slabs does not completely cover these exposed bars, making it easy for workers to be injured by the exposed steel bars when moving the slabs with the crane. This poses a safety hazard during construction and hinders the safe lifting and installation of composite slabs. Utility Model Content

[0004] The purpose of this application is to provide a prefabricated composite slab construction hoisting tool to solve the problem mentioned in the background art that during the hoisting of composite slabs, workers are needed to assist in the installation work, but some of the reinforcing bars on the edges of the composite slabs are exposed. When the composite slabs are tied with slings, the exposed reinforcing bars cannot be wrapped, which makes it easy for workers to be scratched by the exposed reinforcing bars when they move the composite slabs with the crane, causing personal safety accidents during construction operations and hindering the safe hoisting and installation of composite slabs.

[0005] To achieve the above objectives, this application provides the following technical solution: a prefabricated composite slab construction hoist, including a hook hoisting assembly, on which two reinforcing assemblies are hooked, and on the left and right sides of the two reinforcing assemblies, a enclosure assembly is installed. The hook hoisting assembly is used to hook the composite slab, and the two reinforcing assemblies are used to support the composite slab. The two reinforcing assemblies, together with the two enclosure assemblies, can enclose the composite slab.

[0006] The enclosure assembly includes two long plates, two L-shaped connecting plates, a wide plate, and two locking bolts. The long plates have several first through holes, and the L-shaped connecting plates have several second through holes. The first and second through holes are arranged linearly. The locking bolts pass through the corresponding first and second through holes to fix the long plates and L-shaped connecting plates. Two first sliders are fixed on the inner side of the L-shaped connecting plates. The long plates have first sliding grooves that match the first sliders. The outer side of the L-shaped connecting plates has second sliders, and the wide plate has second sliding grooves that match the second sliders.

[0007] Furthermore, the long plate and the wide plate are arranged perpendicularly, and the wide plate and the two L-shaped connecting plates are arranged in a "U" shape.

[0008] Furthermore, the reinforcement component includes an L-shaped clamping plate and a pin. A nose ring is fixed to the top of the L-shaped clamping plate. Two long plates in the same enclosure component are respectively installed on the two L-shaped clamping plates in the two reinforcement components, and a reinforcement block is fixed between the long plate and the L-shaped clamping plate.

[0009] Furthermore, a carrier tube is rotatably connected to the L-shaped card plate via a pin shaft. A fixing block is fixed to the outer wall of the carrier tube, and a support plate is fixed to the fixing block. Both the L-shaped card plate and the support plate are provided with pin holes for the pin to pass through. A limiting sleeve is sleeved on the outside of the pin, and the pin is threadedly connected to the limiting sleeve.

[0010] Furthermore, the hook assembly includes a square frame and a carrier ring. Two first steel ropes are fixed to the lower part of the square frame, and a first hook is fixed to the bottom end of each first steel rope. The first hook is used to hook the nose ring. Fixed rings are fixed to the four corners of the upper part of the square frame.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example: Reference Figure 1-8 The diagram shows a prefabricated composite slab construction hoisting tool, including a hook lifting assembly with two reinforcing components hooked onto it. Enclosure components are installed on the left and right sides of each of the two reinforcing components. The hook lifting assembly is used to hook the composite slab, and the two reinforcing components are used to support the composite slab. The two reinforcing components, together with the two enclosure components, can enclose the composite slab, thus covering the exposed reinforcing bars on the composite slab and preventing them from scratching workers during hoisting and installation, ensuring construction safety.

[0027] The enclosure assembly includes two long plates 1, two L-shaped connecting plates 2, a wide plate 3, and two locking bolts 6. The long plates 1 and the wide plates 3 are set perpendicularly, and the wide plates 3 and the two L-shaped connecting plates 2 are arranged in a "U" shape. The long plates 1 have multiple first through holes 4, and the L-shaped connecting plates 2 have multiple second through holes 5. The multiple first through holes 4 and the multiple second through holes 5 are arranged linearly. The locking bolts 6 can fix the long plates 1 and the L-shaped connecting plates 2 after passing through the corresponding first through holes 4 and second through holes 5. Two first sliders 7 are fixed on the inner side of the L-shaped connecting plates 2. The long plates 1 have a first sliding groove 9 that matches the first sliders 7. The outer side of the L-shaped connecting plates 2 has a second slider 8, and the wide plates 3 have a second sliding groove 10 that matches the second slider 8.

[0028] The first slider 7 on the L-shaped connecting plate 2 slides along the first groove 9 on the long plate 1 to adjust the combined length of the long plate 1 and the L-shaped connecting plate 2, so as to adapt to the wrapping requirements of composite plates of different lengths. The second slider 8 on the L-shaped connecting plate 2 can slide along the second groove 10 on the wide plate 3 to adjust the combined width of the two L-shaped connecting plates 2 and the wide plate 3, so as to adapt to the wrapping requirements of composite plates of different widths. In this way, the use of this lifting tool can meet the wrapping requirements of composite plates of different sizes and ensure the safety of composite plates during hoisting and installation.

[0029] The reinforcement component includes an L-shaped clamping plate 11 and a pin 17. A nose ring 12 is fixed to the top of the L-shaped clamping plate 11. Two long plates 1 in the same enclosure component are respectively installed on the two L-shaped clamping plates 11 in the two reinforcement components. A reinforcement block 13 is fixed between the long plate 1 and the L-shaped clamping plate 11. A carrier tube 14 is rotatably connected to the L-shaped clamping plate 11 through a pin shaft. A fixing block 15 is fixed to the outer wall of the carrier tube 14. A support plate 16 is fixed to the fixing block 15. Both the L-shaped clamping plate 11 and the support plate 16 are provided with pin holes 19 for the pin 17 to pass through. A limiting sleeve 18 is sleeved on the outside of the pin 17, and the pin 17 is threadedly connected to the limiting sleeve 18.

[0030] The pin 17 is passed through the pin hole 19 on the support plate 16 and the pin hole 19 on the L-shaped clamping plate 11, so that the pin 17 and the pin can lock the position of the support plate 16. In this way, the L-shaped clamping plate 11 and the support plate 16 can be clamped on the composite plate. The two reinforcing components can strengthen the stability of the support when hoisting the composite plate, and further improve the safety of hoisting the composite plate. The limit sleeve 18 is screwed onto the pin 17 to prevent the pin 17 from falling off during the hoisting of the composite plate. When the composite plate needs to be installed, the worker can pull out the pin 17, so that the support plate 16 relies on its own weight to rotate and hang down around the carrier pipe 14, no longer blocking the composite plate, and facilitating its quick installation.

[0031] The hook assembly includes a square frame 20 and a carrier ring 24. Two first steel ropes 21 are fixed to the lower part of the square frame 20. A first hook 22 is fixed to the bottom end of the first steel rope 21. The first hook 22 is used to hook the nose ring 12. Fixing rings 23 are fixed to the four corners of the upper part of the square frame 20. Four second steel ropes 25 are fixed to the carrier ring 24. A second hook 26 is fixed to the bottom end of the second steel rope 25. The four second hooks 26 are used to hook the four fixing rings 23 respectively. Four third steel ropes 27 are fixed to the lower part of the square frame 20. A third hook 28 is fixed to the bottom end of the third steel rope 27. The four third hooks 28 are used to hook the composite plate.

[0032] The first hook 22 is hooked onto the nose ring 12, the third hook 28 is hooked onto the composite slab, and the crane hook is used to hook the carrier ring 24. Then the composite slab can be hoisted.

[0033] Working principle of this utility model:

[0034] First, adjust the size of the enclosure components according to the required size of the composite slab for construction. The adjustment method is as follows: First, remove the locking bolt 6 from the long plate 1 and the L-shaped connecting plate 2. Then, pull the long plate 1 and the L-shaped connecting plate 2 to adjust the combined length of the two to match the length of the composite slab. After the position of the long plate 1 and the L-shaped connecting plate 2 is adjusted, remove the locking bolt 6 and pass it through the corresponding first through hole 4 and second through hole 5. Use the locking bolt 6 to lock the position of the long plate 1 and the L-shaped connecting plate 2. Then, pull the two L-shaped clamping plates 11 so that the two L-shaped connecting plates 2 and the wide plate 3 can match the width of the composite slab. In this way, the two reinforcement components and the two enclosure components can surround the four sides of the composite slab.

[0035] The pin 17 is passed through the pin hole 19 on the support plate 16 and the pin hole 19 on the L-shaped clamping plate 11, and its position is locked by the limiting sleeve 18, so that the L-shaped clamping plate 11 and the support plate 16 can be clamped on the composite plate. The first hook 22 is hooked on the nose ring 12, and the third hook 28 is hooked on the composite plate. The crane hook is used to hook the carrier ring 24, and then the composite plate can be hoisted. When the composite plate needs to be installed, the worker can pull out the pin 17, so that the support plate 16 relies on its own weight to rotate and hang down around the carrier pipe 14, no longer obstructing the composite plate, which facilitates its quick installation. The two reinforcement components and the two enclosure components can wrap the exposed steel bars of the composite plate to prevent them from scratching the workers.
