Description

Technical Field

[0001] This invention relates to the field of construction technology, specifically to an improved hanging basket system for cantilever structure formwork. Background Technology

[0002] In building construction projects, cantilever structures are frequently encountered. The conventional practice for constructing cantilever structures is to erect a ground-supported formwork underneath them; or to install a cantilevered steel support frame on the lower floor structure, and then erect the formwork frame on the support frame platform.

[0003] The drawback of conventional practices is that: 1. Ground-supported formwork requires a large amount of scaffolding, especially when the cantilever structure is located at a high altitude. The amount and cost of the scaffolding erected from the ground to the height of the cantilever structure cannot be underestimated. On the other hand, the extremely high scaffolding poses a significant construction risk and places high demands on the stability of the scaffolding. 2. If cantilevered steel support frames are used, a larger amount of formwork will be required when the lower floor has a high ceiling, leading to increased costs. Furthermore, higher ceilings result in a greater load on the support frame, impacting the safety of the cantilevered steel support frames. Additionally, cantilevered steel support frames have limited versatility and are not suitable for varying floor heights. Openings or pre-embedded points at the attachment points of the cantilevered steel support frames to the structure may cause leaks in the exterior facade, potentially affecting facade construction.

[0004] We have developed a patented technology, application number "202521898334.5," for a hanging basket system for cantilever structure formwork, which improves upon the above problems. This technology uses second pulleys fixedly installed on the crossbeams, vertical I-beams, and the top of the crossbars. The first I-beam is connected to the extension layer via steel wire ropes passing through each second pulley. The prismatic frame allows the first I-beam to be simultaneously stretched upwards by the steel wire ropes at both ends, causing the cantilever structure to abut against the bottom of the extension layer. The crossbeams extend above the extension layer, providing tension to one end of the first I-beam, ensuring the entire first I-beam adheres to the bottom of the extension layer, thus stabilizing it. This technology provides significant support to the extension layer. While the initial fixation was good, we discovered over time that the area above the first I-beam at the bottom of the hanging layer was consistently empty, resulting in significant material waste. For large buildings, where the extended layers have large lengths and widths, sufficient steel is required for support, making the first I-beam and the entire structure very heavy, hindering rapid construction. Furthermore, pre-installing fixed pulleys and drilling holes at the bottom of the hanging layer severely reduces the construction team's time. Therefore, improvements were needed to address these issues. We conducted further research and development to solve these problems, subsequently developing an improved hanging basket system for cantilever structure formwork to further optimize the solution.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

[0019] Please see Figure 1-10This invention provides a technical solution: an improved hanging basket system for cantilever structure formwork, comprising a pair of horizontal I-beams 1 set on both sides of the top of a floor slab, the floor slab extending outward to form an extension layer, bolts 2 fixedly installed on each horizontal I-beam 1, a column 11 fixedly connected to one end of each horizontal I-beam 1, a first pulley seat 12 fixedly connected to the other end of each horizontal I-beam 1, a connecting steel 8 fixedly connected to the top of the column 11, and hinge seats 5 fixedly installed on both sides of the bottom of the floor slab. Each hinge seat 5 is provided with a guide rail 501, and a support steel 3 is slidably connected to each guide rail 501. A connecting lug 4 is fixedly installed at one end of the support steel 3. A first steel rope 6 is connected between the connecting lug 4 located on the same side of the extension layer and the first pulley seat 12. The bottom side of the guide rail 501 extends upward to give it a bend 502, and the bend 502 abuts against the support steel 3. A pair of stabilizing steel bars 32 are slidably connected between the two support steel bars 3. The two ends of each stabilizing steel bar 32 are connected to the support steel bars 3. Each of the three sections is equipped with at least two cantilever structures to support the bottom of the extension layer. During installation, the horizontal I-beam 1 is first placed parallel to the top of the floor slab on both sides manually. Then, the horizontal I-beam 1 is locked to the floor slab with bolts 2. The hinge seat 5 is installed manually from the top of the lower floor slab and is also fixed with bolts 2. The end of the support steel 3 is inserted into the guide rail 501, and the other end is lifted by the first steel rope 6. The first steel rope 6 is pulled manually and passed through the first pulley seat 12. One end of the first steel rope 6 is tied manually so that the top of the support steel 3 contacts the bottom of the extension layer. The cantilever structure also follows the support steel 3 as it is lifted to the bottom of the extension layer to support the bottom of the extension layer. Only a single first steel rope 6 is needed to complete the shaping of the extension layer. The support steel 3 is reduced by half and the space utilization of the support steel 3 is increased, which solves the problem of the support steel 3 having a large proportion and wasting materials.

[0020] Furthermore, the cantilever structure includes multiple sliders 25 mounted on the support steel 3. Threaded rods 27 are movably connected to the sliders 25. Locking heads 26 are threadedly fitted onto the outside of the threaded rods 27. Lifting heads 29 are movably connected to the threaded rods 27. Multiple through holes 28 are provided on the outside of the threaded rods 27. A rope drum 30 is elastically connected to the bottom of the lifting head 29. The rope drum 30 and the through holes 28 are matched in size. When the support steel 3 is not in use, the first steel cable 6 is in a slack state, and the support steel 3 is perpendicular to the ground, allowing access by personnel. The worker rotates each locking head 26 on the support steel 3, causing the locking head 26 to move upwards towards the slider 25 after rotation, pressing down on the slider 25 so that the slider 25 is locked onto the support steel 3, thus fixing the slider 25 onto the support steel 3. The positions of the multiple lifting heads 29 are thus determined. When the support steel 3 is in use, it is rotated 90° so that the multiple lifting heads 29 are located at the bottom of the extension layer. The positions of the multiple lifting heads 29 are relatively spread out, which can provide support for multiple points in the extension layer and improve the stability of the device. The lifting head 29 has elastic extension and retraction, which can effectively absorb the stress after the extension layer is fixed, preventing excessive stress concentration.

[0021] Furthermore, a rod 21 is detachably connected between the two support steels 3. A sleeve 22 is sleeved on the outside of the rod 21. Telescopic rods 24 are fixedly connected to both ends of the sleeve 22. A protective plate 13 is fixedly connected between the two telescopic rods 24. A fixing rod 23 is fixedly connected to both ends of the rod 21. The rod 21 is fixed together with the support steel 3 through the fixing rod 23. The protective plate 13 is placed at the bottom of the extension layer to level the mud at the bottom of the extension layer. A suitable amount of mud can also be placed on the top of the protective plate 13 for later replenishment of mud defects at the bottom of the extension layer, thereby improving the effective protection effect on the bottom of the extension layer. It is worth mentioning that the guard plate 13 needs to be placed horizontally with the ground at all times; otherwise, if the guard plate 13 moves along with the support steel 3, its end will hit the bottom of the extension layer and damage the bottom of the extension layer.

[0022] Furthermore, the connecting steel 8 and the floor slab are flush. The connecting steel 8 has a groove 801, and a transmission gear 803 is rotatably connected to one side of the connecting steel 8. A transmission rack 802 is slidably connected to each groove 801, and a slide rod 9 is fixedly connected between two transmission racks 802. A second steel rope 901 is fixedly installed on the outside of the sleeve 22, and the sleeve 22 is fixed together with the slide rod 9 via the second steel rope 901. A double-sided rack 10 is fixedly connected to each first steel rope 6, and the bottom of the double-sided rack 10 meshes with the transmission gear 803. The transmission gear 803 and the transmission rack 802 mesh together. When the support steel 3 is not in use... In this situation, the second steel rope 901 is taut, and the guard plate 13 and the support steel 3 are always overlapping. When the support steel 3 needs to be used, the first steel rope 6 can be pulled manually, causing it to move on the connecting steel 8. As the first steel rope 6 moves, the bottom of the double-sided rack 10 drives the transmission gear 803 to rotate, causing the transmission gear 803 to drive the transmission rack 802 to move towards the extension layer. This slacks the second steel rope 901 connected to the sleeve 22, and the support steel 3 is suddenly pulled by the first steel rope 6, causing the guard plate 13 to move. (See attached diagram) Figure 5 As shown, the center of gravity of the guard plate 13 is located on its left side. When the support steel 3 rotates, the guard plate 13 will gradually tilt to its left. Under the pulling action of the first steel rope 6, the second steel rope 901 will gradually loosen. At the same time, when the second steel rope 901 is loosened, it remains connected to the sleeve 22, effectively preventing the guard plate 13 from rotating counterclockwise due to its own counterweight tilting to the left, thus preventing the guard plate 13 from tilting upwards. In this way, the speed of the second steel rope 901 can maintain the guard plate 13 at a constant speed. During this period, it is convenient for workers to fill the guard plate 13 with mud filler when the guard plate 13 is close to horizontal. The material of the guard plate 13 can be made of non-slip material to prevent the mud on the guard plate 13 from flowing out.

[0023] Furthermore, a lifting rod 7 is fixedly connected between the same ends of the two connecting steel bars 8. A limiting plate 701 is fixedly installed in the middle of the lifting rod 7. The second steel rope 901 and the limiting plate 701 are slidably connected. The limiting plate 701 protrudes forward to prevent the second steel rope 901 from rubbing against the bottom of the extension layer and causing damage.

[0024] Furthermore, limit clips 16 are fixedly connected to both ends of the connecting steel 8. The width of the limit clips 16 and the double-sided rack 10 are matched. The limit clips 16 prevent the double-sided rack 10 from turning during movement, thereby preventing the double-sided rack 10 and the transmission gear 803 from failing to mesh.

[0025] Furthermore, a second supporting steel 15 is fixedly connected between the horizontal I-beam 1 and the column 11, and a first supporting steel 14 is fixedly connected between the connecting steel 8 and the column 11, which effectively improves the stability of the horizontal I-beam 1 and the connecting steel 8.

[0026] Furthermore, a gear positioning seat 17 is fixedly connected to one end of the connecting steel 8, and a second helical gear 20 is fixedly connected to one side of the gear positioning seat 17. A rope drum 30 is rotatably connected to the middle of the connecting steel 8, and a rotating rod 18 is fixedly connected to one end of the rope drum 30. A first helical gear 19 is fixedly connected to one end of the rotating rod 18. The first helical gear 19 and the second helical gear 20 mesh. A third steel rope 31 is wound on the rope drum 30. Side plates 1301 are hinged to both sides of the guard plate 13. The third steel rope 31 and the side plates 1301 are fixedly connected together. A drive gear (not shown, but can be seen when installing this device) is installed on the gear positioning seat 17. (Self-installed) The drive gear and double-sided rack 10 mesh. When the first steel rope 6 is pulled manually to move the double-sided rack 10, the top of the double-sided rack 10 can drive the drive gear to rotate. When the drive gear rotates, it can drive the second helical gear 20 to rotate. At the same time, the first helical gear 19 will also rotate, causing the rotating rod 18 to rotate, which in turn causes the rope drum 30 to rotate. This causes the third steel rope 31 to rise and coil on the rope drum 30, so that the side plate 1301 is in a flat state with the guard plate 13 through the hinge movement, completely covering the bottom of the extension layer and improving the support effect of the guard plate 13. The third steel rope 31 can be wound around the rope drum 30 multiple times to increase the descent length of the third steel rope 31. The side plate 1301 is to make way for the guard plate 13 during rotation. The side plate 1301 prevents interference with the lifting head 29 on the stabilizing steel bar 32 and the support steel 3, thereby interfering with the rotation of the guard plate 13.
