Description

Technical Field

[0001] This utility model relates to a unitized curtain wall hoisting system that can be quickly installed and disassembled, and belongs to the field of curtain wall hoisting technology. Background Technology

[0002] For example, a unitized curtain wall hoisting device disclosed in application number 202410609575.7 includes a track with a combined electric chain hoist on it. Multiple cantilever beams are located above the track, and a tying mechanism connects the cantilever beams to the track. Two fixing mechanisms and a tensioning mechanism are located on each cantilever beam, with a pulling mechanism located on the side of the tensioning mechanism away from the cantilever beam. This device is easy to assemble and operate, solving the problems of inconvenience, long construction period, and high manpower and material consumption associated with traditional vertical transportation and installation of curtain walls. It significantly reduces the workload of workers, accelerates on-site construction progress, and improves the safety of vertical transportation and installation of curtain walls. Furthermore, the device can be reused, reducing manpower and material consumption and lowering construction costs.

[0003] The above-mentioned applications still have shortcomings:

[0004] The welding and bolt fixing method of this type of wall hoisting device has the defects of low efficiency and low safety factor. Although there are some adjustable hoisting devices in the prior art, they lack reliable self-locking mechanism and quick disassembly and assembly function, which makes it difficult to meet the efficiency and safety requirements of modern high-rise building curtain wall construction.

[0005] To address these issues, a unitized curtain wall hoisting system that allows for rapid installation and disassembly was designed. Utility Model Content

[0006] The main purpose of this utility model is to provide a unitized curtain wall hoisting system that can be quickly installed and disassembled.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A unitized curtain wall hoisting system that can be quickly installed and disassembled includes a curtain wall unit, with side columns symmetrically distributed on both sides of the curtain wall unit, and an upper horizontal beam installed at the outer end of the side columns;

[0009] Two wedge-shaped hooks are symmetrically engaged on the upper crossbeam. Lifting rings are installed on the two wedge-shaped hooks and are fixedly connected to the T-shaped steel beam.

[0010] Wedge hook one, wedge hook two and lifting ring are connected by a fixed assembly, and a lifting assembly is installed at the center of the T-shaped steel beam.

[0011] Preferably, the fixing components include a slot, a latch, and a bolt;

[0012] Wedge hook one and wedge hook two have slots, and the lifting ring clamps the two sides of wedge hook one and wedge hook two with bolts passing through and fixing them. Wedge hook one and wedge hook two are fixed by bolts passing through and fixing them.

[0013] Preferably, the lifting assembly includes a lifting lug and a steel chain. The lifting lug is installed at the center of the T-shaped steel beam, and the steel chain is suspended on the lifting lug. The lifting lug and the steel chain are connected by an anti-derailment buckle assembly.

[0014] Preferably, wedge hook one and wedge hook two are self-locking by engaging with slots.

[0015] Preferably, the slot slides and locks itself on the sidewalls of wedge hook one and wedge hook two.

[0016] Preferably, wedge-shaped hook one and wedge-shaped hook two are inserted into the upper crossbeam, and the slots fit against the side wall of the upper crossbeam.

[0017] Preferably, wedge hook one and wedge hook two are in the shape of a double oblique wedge lock, and the protruding part of wedge hook two is inserted into the drain hole of the upper crossbeam.

[0018] The beneficial technical effects of this utility model are as follows:

[0019] This utility model provides a unitized curtain wall hoisting system that can be quickly installed and disassembled.

[0020] Wedge hook one and wedge hook two achieve self-locking through the engagement of double oblique wedge locks and slots; the lifting ring and T-shaped steel beam are fixed by high-strength bolts.

[0021] The end of the bolt is locked with a nut. The groove can slide along the side wall of the groove during the double wedge lock engagement until it reaches the self-locking position. All connection points (such as bolts and bolts) are designed to be detachable for easy maintenance and replacement.

[0022] To further enhance the structural stability, the bolts are designed to pass through the transverse through holes of wedge hook one and wedge hook two. The ends of the bolts are fixed with nuts by threads. This connection method not only restricts the axial displacement of the hooks and slots, but also improves the tensile and shear strength of the overall structure, ensuring that it will not loosen or fall off during hoisting. The lifting rings are connected to the pre-reserved holes in the web of the T-shaped steel beam by bolts. This connection method facilitates installation and disassembly.

[0023] The upper part of the T-shaped steel beam is equipped with lifting lugs, which are connected to steel chains with anti-detachment buckles. This design further enhances the safety of hoisting and prevents the steel chains from accidentally falling off during hoisting. The double wedge lock automatically engages with the side wall of the slot, eliminating the need for complex adjustments. The bolts and transverse through holes work together to fix the hooks and prevent them from loosening. Loosening the nuts releases the bolts, allowing the hooks to separate from the curtain wall for easy maintenance. The T-shaped steel beam and the steel chain form a multi-load-bearing structure with strong impact resistance. Attached Figure Description

[0038] Example 1

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment proposes a unitized curtain wall hoisting method that can be quickly installed and disassembled. In the design of the curtain wall unit, the side columns and the upper and lower horizontal beams are the core support structures. Wedge-shaped hook one and wedge-shaped hook two are installed in the groove of the upper horizontal beam. These two hooks adopt a double oblique wedge lock structure and are in a back-to-back wedge-tight state.

[0040] The key to this design lies in the angle of the hook's inclination, which is controlled between 4.5° and 5°. Through the precise angle of the inclination, the hook can tightly engage with the side wall of the upper crossbeam groove, forming a self-locking mechanism. Furthermore, the wedge-shaped hook is connected to the drain hole of the upper crossbeam water groove, ensuring stability and safety during the hoisting process.

[0041] The slot is located above wedge hook one and wedge hook two. It fits into the lifting lugs of wedge hook one and wedge hook two through the rectangular opening in the middle. The slot has a U-shaped structure, which presses the upper crossbeam between the slot and wedge hook one and wedge hook two, ensuring a tight connection between the upper crossbeam and the hook.

[0042] Example 2

[0043] Mechanical engagement: Wedge hook 5 and wedge hook 6 achieve self-locking through the engagement of double oblique wedge locks with slot 4.

[0044] Bolted connection: The lifting ring 9 is fixed to the T-shaped steel beam 10 by high-strength bolts 8; the end of the clamp 7 is locked with a nut.

[0045] Sliding fit: During the double wedge lock engagement process, the slot 4 can slide along the side wall of the slot until it reaches the self-locking position.

[0046] Detachable connection: All connection points, such as bolts and clips, are designed to be detachable for easy maintenance and replacement.

[0047] To further enhance the structural stability, the bolts are designed to pass through the transverse through holes of wedge hook one and wedge hook two. The ends of the bolts are fixed to the nuts by threads. This connection method not only restricts the axial displacement of the hooks and slots, but also improves the tensile and shear strength of the overall structure, ensuring that it will not loosen or fall off during hoisting.

[0048] The lifting ring is connected to the pre-drilled holes in the web of the T-shaped steel beam by bolts. This connection method facilitates installation and disassembly.

[0049] The upper part of the T-shaped steel beam is equipped with lifting lugs, which are connected to steel chains with anti-detachment buckles. This design further enhances the safety of hoisting and prevents the steel chains from accidentally falling off during hoisting.

[0050] Example 3

[0051] Insert wedge hook 15 and wedge hook 26 back to back into the slot of the upper crossbeam 3, and push the slot 4 to make the inclined surface of the double wedge lock fit against the side wall of the slot.

[0052] The wedge-shaped inclined surface generates friction under the action of thrust, achieving self-locking; inserting the bolt 7 and tightening the nut further restricts the displacement of the hook.

[0053] The lifting ring 9 is fixed to the reserved hole in the web of the T-shaped steel beam 10 by bolts 8. After the steel chain 12 is connected to the lifting lug 11, the lifting equipment is started to complete the curtain wall lifting.

[0054] The double wedge lock continuously presses against the side wall of the slot under the action of gravity, and the bolt 7 prevents the hook from loosening, forming a double lock.

[0055] The T-shaped steel beam 10 distributes the force through the pre-reserved holes in the web, and the anti-detachment buckle of the steel chain 12 ensures stability during the hoisting process;

[0056] Loosen the nut at the end of the bolt 7 and pull out the bolt 7; push the groove 4 in the opposite direction to release the double wedge lock engagement;

[0057] Pull out wedge hook 1 5 and wedge hook 2 6 to complete the separation of curtain wall unit 1. During the overall hoisting process, the curtain wall unit hoisting system ensures the stability and safety of the hoisting through precise mechanical connection and self-locking mechanism. This design not only improves construction efficiency but also greatly reduces the risks in the hoisting process, and is suitable for various complex building environments and construction conditions.

[0058] Through this structural design, the curtain wall unit can achieve rapid and safe installation while ensuring strength, meeting the dual requirements of modern buildings for efficient construction and safety.

[0059] The scope of protection of this invention is defined by the claims. Any modifications, equivalent substitutions, or improvements made by those skilled in the art within the scope defined by the claims of this invention should be included within the scope of protection of this invention.

[0060] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
