Abstract
Description
Technical Field
[0001] This utility model relates to the field of floor slab handling technology, and in particular to a prefabricated composite floor slab construction device. Background Technology
[0002] When moving composite floor slabs, they are transported by cranes. However, existing hoisting equipment has poor structural adjustment capabilities and is not convenient to adjust to accommodate different lengths of floor slabs. It cannot effectively prevent the floor slabs from overturning due to uneven stress points caused by excessive extension. The composite slabs may overturn during hoisting, posing certain safety hazards. Therefore, a prefabricated composite floor slab construction device is proposed. Utility Model Content
[0003] The present invention aims to solve the technical problems existing in the prior art and provide a prefabricated composite floor slab construction device.
[0004] To achieve the above objectives, this utility model adopts the following technical solution, including a lifting plate, a connecting base at the top of the lifting plate, the connecting base being hollow, the lifting plate being inserted into the connecting base via an installation shaft and locked in place by a nut, a lifting ring at the top of the connecting base, and docking bases fixedly installed on both sides of the top of the lifting plate, an additional sleeve plate fitted on top of the connecting base, and locking slots on the top of both the additional sleeve plate and the docking base, a reinforcing connecting rod installed between the additional sleeve plate and the corresponding docking base, and equidistantly arranged installation sleeves embedded inside the lifting plate, with installation bolts inserted inside the installation sleeves, an adjusting chain hanging below the installation bolts, and a positioning clip below the installation bolts, the positioning clip having a locking groove for locking the floor slab inside.
[0005] Furthermore, an installation ring is fixedly installed at the lower end of the installation bolt, the top of the installation bolt has a threaded column structure, and a limiting nut is fitted onto the top of the installation bolt after it passes through the installation sleeve.
[0006] Furthermore, a locking hole is provided at the center of the inner bottom surface of the locking groove, and a tightening bolt for adjusting rotation is inserted into the locking hole. The top of the tightening bolt is a rubber ball structure.
[0007] Furthermore, two mutually spaced support bases are fixedly installed on the lower surface of the positioning card, the width of the support bases corresponds to the width of the positioning card, and a long strip-shaped buffer pad is installed under each of the two support bases.
[0008] Furthermore, an anti-slip layer is installed and fixed on the inner upper surface of the groove. When the floor slab is inserted into the groove and squeezed by the upper end of the clamping bolt, it comes into contact with the anti-slip layer, increasing the friction.
[0009] This utility model provides a prefabricated composite floor slab construction device, which has the following beneficial effects:
[0010] 1. A prefabricated composite floor slab construction device, comprising positioning clips for clamping and fixing the floor slab, wherein after the positioning clips are fitted onto the outside of the floor slab, when the floor slab enters the inside of the clamping groove and touches the bottom, the tightening bolts are continuously rotated. The rubber ball at the top of the tightening bolt presses against the surface of the floor slab, pushing the floor slab into contact with the anti-slip layer. The friction force on the upper and lower sides of the floor slab increases, making it less likely for the floor slab to fall off after clamping. During hoisting, multiple positioning clips are clamped onto the sides of the floor slab to fix it. After the installation bolts are inserted into the installation sleeves to adjust the position and change the balance of the floor slab, the multiple installation bolts drive the positioning clips to hoist the floor slab in a balanced manner, reducing the possibility of the floor slab flipping during hoisting and movement, and greatly improving the stability of the hoisted floor slab during movement. At the same time, since the installation bolts can flexibly change position, they can drive the positioning clips to adjust when dealing with floor slabs of different sizes and shapes, so that the floor slab is relatively parallel to the bottom surface after hanging, improving the applicability of the device.
[0011] 2. A prefabricated composite floor slab construction device, comprising an adjustable and rotatable hoisting plate, wherein the mounting shaft at the top of the hoisting plate is inserted into the connecting base and locked in place by a nut, and a fitting ring is installed at the top of the connecting base for fitting onto the hook of a crane. After the floor slab is hoisted below the hoisting plate by multiple positioning clips, the position of the floor slab is balanced to the water level by adjusting the position of the mounting bolts. A reinforcing connecting rod is installed between the mounting plate and the connecting base to enhance the stability of the hoisting plate after installation. The entire hoisting plate can be rotated laterally during hoisting to adjust the position of the floor slab, making the disassembly of the floor slab more convenient and greatly improving the convenience of the device.

[0018] A prefabricated composite floor slab construction device, such as Figures 1 to 3 As shown, the system includes a lifting plate 1, with a connecting base 2 on top of the lifting plate 1. The connecting base 2 has a hollow interior. The lifting plate 1 is inserted into the connecting base 2 via an installation shaft and locked in place with a nut. A lifting ring is installed on the top of the connecting base 2. A docking base 5 is fixedly installed on both sides of the top of the lifting plate 1. An additional sleeve plate 3 is fitted on top of the connecting base 2. Both the additional sleeve plate 3 and the docking base 5 have locking slots on their tops. Through holes for mounting bolts are provided in the slots on the outside of the additional sleeve plate 3 and the docking base 5. A reinforcing connecting rod 4 is installed between the additional sleeve plate 3 and the corresponding docking base 5. After the entire lifting plate 1 is installed below the connecting base 2, it is fixed and balanced by the two reinforcing connecting rods 4. Since the lifting plate 1 is movably installed below the connecting base 2 via an installation shaft, the entire lifting plate 1 can be adjusted by lateral rotation during use.
[0019] The installation plate 1 is embedded with equidistantly arranged installation sleeves 6. Installation bolts 7 are inserted into the installation sleeves 6. An adjustment chain is hung below the installation bolts 7. A positioning clip 8 is provided below the installation bolts 7. The positioning clip 8 has a clip groove 10 for clamping the floor slab inside.
[0020] The lower end of the mounting bolt 7 is fixedly installed with a mounting ring. The top of the mounting bolt 7 is a threaded column structure. After the top of the mounting bolt 7 passes through the mounting sleeve 6, a limiting nut is fitted on it. The plug-in type mounting bolt 7 can change the insertion position as needed to match different sizes of floor slabs.
[0021] A locking hole 11 is provided at the center of the bottom surface of the locking groove 10. A tightening bolt 12 for adjusting rotation is inserted into the locking hole 11. The top of the tightening bolt 12 is a rubber ball structure. An anti-slip layer 14 is embedded in the upper surface of the locking groove 10. After the floor slab is inserted into the locking groove 10, the floor slab is moved up by rotating the tightening bolt 12. The floor slab contacts the surface of the anti-slip layer 14, increasing the friction and making it difficult for the entire positioning clip 8 to fall off after it is set on the side of the floor slab.
[0022] Two mutually spaced support bases 9 are fixedly installed on the lower surface of the positioning clip 8. The width of the support base 9 corresponds to the width of the positioning clip 8. A long strip of buffer pad 13 is installed under both support bases 9. When the floor slab is hoisted and placed, the buffer pad 13 at the bottom of the positioning clip 8 reduces the impact force when it is lowered, thus reducing the impact on the floor slab.
[0023] The working principle of this utility model:
[0024] By setting up positioning clips 8 for clamping and fixing the floor slab, after the positioning clips 8 are fitted onto the outside of the floor slab, when the floor slab enters the inside of the clamping groove 10 and touches the bottom, the tightening bolt 12 is continuously rotated. The rubber ball at the top of the tightening bolt 12 presses against the surface of the floor slab and pushes the floor slab into contact with the anti-slip layer 14. The friction force on the upper and lower sides of the floor slab increases, making it less likely for the floor slab to fall off after clamping. During the hoisting process, the floor slab is fixed by clamping multiple positioning clips 8 on the side of the floor slab. After the mounting bolts 7 are inserted into the mounting sleeves 6 to adjust the position and change the balance of the floor slab, the multiple mounting bolts 7 drive the positioning clips 8 to hoist the floor slab in a balanced manner, reducing the possibility of the floor slab flipping during hoisting and movement, and greatly improving the stability of the hoisted floor slab during movement. At the same time, since the mounting bolts 7 can flexibly change position, they can drive the positioning clips 8 to adjust when dealing with floor slabs of different sizes and shapes, so that the floor slab is relatively parallel to the bottom surface after hanging, improving the applicability of the device.
[0025] The system features an adjustable and rotatable lifting plate 1. The mounting shaft at the top of the lifting plate 1 is inserted into the connecting base 2 and locked in place with a nut. A fitting ring is installed on the top of the connecting base 2 to fit onto the crane hook. After the floor slab is lifted below the lifting plate 1 using multiple positioning clips 8, the position of the mounting bolts 7 is adjusted to balance the floor slab to the water level. A reinforcing connecting rod 4 is installed between the mounting sleeve 3 and the docking base 5 to enhance the stability of the lifting plate 1 after installation. The entire lifting plate 1 can be rotated laterally during the lifting process to adjust the position of the floor slab, making the disassembly of the floor slab more convenient and greatly improving the device's usability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
