Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a cantilevered unloading platform. Background Technology

[0002] As is well known, a material unloading platform is a temporary operating platform erected on the main body of a building [1], which can be used to carry materials within a certain construction period. The main body of the building includes at least two floor slabs 10 arranged at intervals. The edges of the floor slabs 10 are provided with crossbeams 11, and the crossbeams 11 are connected by at least two columns 12. The use of a material unloading platform can significantly accelerate the construction progress of the project. In today's rapidly developing construction industry, a material unloading platform is indispensable.

[0003] Unloading platforms are typically connected to the main building structure via steel wire ropes. One end of the wire rope is usually secured to the structure using embedded parts such as lifting rings or ground anchors. In this case, the embedded parts need to be reliably tied to the reinforcing bars of the main building structure and integrally cast together. Furthermore, during later processing, the exposed portions of the embedded parts need to be cut off. This method is extremely labor-intensive and resource-intensive, and the embedded parts cannot be reused. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cantilevered unloading platform that can be dismantled after use and reused multiple times.

[0005] The technical solution adopted by this utility model to solve its technical problem is a cantilevered unloading platform, including a placement platform. A first lifting ring and a second lifting ring are arranged at intervals on both sides of the placement platform. The second lifting ring is located outside the first lifting ring. A first steel rope is sleeved on each first lifting ring, and a second steel rope is arranged on each second lifting ring. A first connecting structure is provided at the end of the placement platform. A second connecting structure is provided at the end of each first steel rope away from the first lifting ring. A third connecting structure is provided at the end of each second steel rope away from the second lifting ring.

[0006] The first connecting structure includes a first steel section and a second steel section disposed on the upper and lower sides of the platform.

The second connecting structure includes a third steel section and a fourth steel section arranged vertically opposite to each other. A second installation space for placing a floor slab is formed between the third steel section and the fourth steel section. Two second screw rods are fixedly connected to the lower surface of the third steel section. A second through hole is provided on the fourth steel section to cooperate with the second screw rods. The second steel rope passes through the second through hole and is threadedly connected to the second nut below the fourth steel section. A connecting ring is fixedly connected to the upper surface of the third steel section. The end of the first steel rope away from the first lifting ring is connected to the connecting ring. The third connecting structure includes a fifth steel section and a sixth steel section arranged opposite to each other. A third installation space for placing a crossbeam is formed between the fifth steel section and the sixth steel section. Two third screws are fixedly connected to the side walls opposite to the fifth steel section and the sixth steel section. A third through hole is provided on the sixth steel section to cooperate with the third screws. The third screws pass through the third through hole and are threadedly connected to the third nut.

[0022] The first lifting ring 2 and the second lifting ring 3 are fixed to both sides of the platform 1 by welding. After installation, the second lifting ring 3 is closer to the edge of the floor slab 10 than the first lifting ring 2, forming a double-lifting-point layout. The end of the first steel rope 4 is equipped with a wire rope buckle and is sleeved on the first lifting ring 2; the end of the second steel rope 5 is also connected to the second lifting ring 3 through a wire rope buckle. This design ensures a reliable connection between the steel rope and the lifting ring and facilitates disassembly.

[0023] The first steel section 601 and the second steel section 603 are angle steel or I-beams. The first steel section 601 is positioned above the second steel section 603. Two vertical first screws 602 are fixed to the first steel section 601 by welding or integral forming. In actual use, vertical through holes are drilled in the floor slab 10. The two first screws 602 clamp the I-beam beam 101. Then, the first screws 602 pass through the through holes in the floor slab 10 and the first through holes in the second steel section 603 in sequence, and are locked with first nuts. This achieves clamping of the floor slab 10 below and fixes the storage platform 1 to the edge of the floor slab 10. After installation, part of the storage platform 1 is located on the floor slab 10, and the other part extends out of the floor slab 10, forming a cantilever structure. The third type of steel 701 and the fourth type of steel 704 are angle steel or I-beams, with the third type of steel 701 located above the fourth type of steel 704. Two vertical second screws 702 are fixed to the third type of steel 701 by welding or integral forming. Vertical through holes are drilled in the floor slab 10, and the second screws 702 pass through the through holes in the floor slab 10 and the second through holes in the fourth type of steel 704 in sequence, and are locked with second nuts to achieve clamping of the upper floor slab 10.

Through holes are drilled in the crossbeam 11, and the third screw 802 passes through the through holes in the crossbeam 11 and the sixth type steel 806 in sequence, and is locked with the third nut to clamp the crossbeam 11. A fixing ring can be used as the connecting component, and the end of the second steel rope 5 can be fixed to the fixing ring with a wire rope buckle, transmitting the load to the main structure through the crossbeam 11.

[0024] The specific installation process of this utility model:

[0025] The platform 1 is lifted to the installation position using a crane. At this time, one end of the platform 1 is located on the upper surface of the floor slab 10 below, and the other end is suspended in the air. A vertical through hole is drilled in the floor slab 10 below. The first steel section 601 is placed on the upper surface of the floor slab 10 below, and the second steel section 603 is placed on the lower surface of the floor slab 10 below. The two first screws 602 on the first steel section 601 clamp the I-beam 101. Then the first screws 602 pass through the through hole on the floor slab 10 and the first through hole on the second steel section 603 in sequence, and are locked with the first nut. This achieves the clamping of the floor slab 10 below and fixes the platform 1 to the edge of the floor slab 10. Vertical through holes are drilled in the upper floor slab 10. The third steel section 701 and the fourth steel section 704 are located on the upper and lower sides of the upper floor slab 10, respectively. The second screw 702 on the third steel section 701 passes through the through hole in the upper floor slab 10 and connects to the second through hole on the fourth steel section 704, and is locked with a second nut, thus clamping the upper floor slab 10. A connecting ring 703 is located on the third steel section 701. Wire rope buckles are installed at both ends of the first steel rope 4, connecting the first lifting ring 2 and the connecting ring 703. Horizontal through holes are drilled in the crossbeam 11. The third screw 802 on the fifth steel section 801 passes through the through holes in the crossbeam 11 and the third through hole on the sixth steel section 806 in sequence, and is locked with a third nut, thus clamping the crossbeam 11. This completes the installation of the storage platform 1.

[0026] The aforementioned storage platform 1 could be constructed from a single piece of steel plate. However, this design would result in excessive load and could potentially damage the main structure. Further details can be found in [link to relevant documentation]. Figure 2 and Figure 3 The storage platform 1 includes two opposing H-beams 101. Each H-beam 101 is equipped with a first lifting ring 2 and a second lifting ring 3. The two H-beams 101 are connected by at least two connecting beams 102. A storage plate 9 is provided above the connecting beams 102. A frame 901 is provided on the storage plate 9. The frame 901 has opposing first openings 902 and second openings 903. The first lifting ring 2 and the second lifting ring 3 are welded to each H-beam 101 and fixed by welding with at least two transverse connecting beams 102 to form a rigid frame.

[0027] To facilitate the hoisting of the storage platform 1 to the installation location, further refer to... Figure 3 The platform 9 is provided with four evenly distributed lifting rings 904. A lifting ring 904 is welded to each of the four corners of the platform 9 to assist in lifting or fixing temporary equipment and enhance the functionality of the platform.

[0028] Because there may be height differences between adjacent floors, further details are needed to improve the adaptability of the device. (See also...) Figure 6The connecting assembly includes hinge plates 803 arranged opposite each other on a fifth-section steel 801. Two hinge plates 803 have connecting holes, which are connected by a rotating rod 804. A connecting cylinder 805 is mounted on the rotating rod 804. A threaded rod 501 is provided at the end of the second steel rope 5. The threaded rod 501 passes through the connecting cylinder 805 and is locked by a locking nut 502. Two hinge plates 803 are welded to one of the fifth-section steel 801. The hinge plates 803 have connecting holes and are connected by the rotating rod 804. The middle of the rotating rod 804 is rotatably connected to the connecting cylinder 805. The threaded rod 501 at the end of the second steel rope 5 passes through the connecting cylinder 805 and is secured by the locking nut 502. This allows for adjustment of the tilt angle of the second steel rope 5 and quick locking, improving adaptability and preventing excessive bending of the second steel rope 5, thus extending its service life.

[0029] Furthermore, both the outer surfaces of the first steel rope 4 and the second steel rope 5 are provided with a wear-resistant coating. The wear-resistant coating can be a polyurethane wear-resistant coating, which reduces wear on contact parts such as the first lifting ring 2, the second lifting ring 3, and the connecting ring 703, and extends the service life.

[0030] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
