Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a device and method for hanging and lifting steel formwork for ultra-high independent stiff columns. Background Technology

[0002] Currently, independent columns are widely used in architectural design as vertical load-bearing components in buildings, bridges, and structures. Formwork lifting technology plays a crucial role in the construction of independent stiffened columns. Lifting and transporting formwork is a major construction challenge. Because the formwork is made of wood or steel and needs to be assembled and repeatedly disassembled in circular columns, existing formwork lifting methods mostly employ integrated climbing steel platforms or cantilevered scaffolding. While these methods can meet certain construction needs, in the construction of ultra-high independent stiffened columns, scaffolding needs to be erected around each column, significantly increasing construction time, impacting the project schedule, and indirectly increasing labor and material costs.

[0003] Furthermore, some construction methods require multiple adjustments and fixations of the formwork during the lifting process, resulting in cumbersome construction procedures and hindering rapid and efficient lifting operations. The design of the construction process does not adequately consider the continuity and automation of the lifting process, leading to cumbersome and inconvenient operation and low construction efficiency. Therefore, there is a need to provide a device and method suitable for the hanging and lifting of steel formwork for ultra-high independent stiffened columns, which can solve the problems of inefficiency, inconvenience, cumbersome operation procedures, and high costs associated with the existing technology for lifting ultra-high independent stiffened column formwork. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for lifting and hoisting steel formwork for ultra-high independent stiffened columns, which can solve the problems of inefficient and inconvenient construction, cumbersome operation process and high cost of lifting and hoisting ultra-high independent stiffened column formwork in the prior art.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A device and method for hanging and lifting steel formwork for ultra-high independent rigid columns includes: a steel frame, formwork lifting equipment, support rods, steel connectors, and steel fasteners; the upper ends of several support rods are respectively installed at the bottom of the steel frame, and the lower end of each support rod is equipped with a steel connector, which can be matched and snapped onto the steel of the ultra-high independent rigid column and locked and fixed by a pair of steel fasteners, so that the steel frame is horizontally erected above the steel of the ultra-high independent rigid column; the length and width of the steel frame are not less than the length and width of the ultra-high independent rigid column, and several formwork lifting devices are respectively spaced on the steel frame, so that several steel formwork panels of the ultra-high independent rigid column are respectively hung below the hooks of the several formwork lifting devices, and the several steel formwork panels can be aligned with the structure of the ultra-high independent rigid column.

[0007] The steel connector is an inverted U-shaped structure with an open bottom. The closed top end of the steel connector is fixedly connected to the lower end of the support rod. The width of the bottom opening of the steel connector is greater than the thickness of the steel of the ultra-high independent stiffened column, so that the steel connector can be snapped onto the steel of the ultra-high independent stiffened column through the bottom opening and locked and fixed by a pair of steel fasteners.

[0008] The steel connector has screw holes on both sides and threaded sections that match the screw holes on the steel fastener. The steel fasteners can penetrate the side walls of the steel connector by rotating through the threads, so that one end of a pair of steel fasteners inside the steel connector can be pressed against the two surfaces of the steel of the ultra-high independent stiffness column.

[0009] The steel fastener is provided with an anti-slip pad at one end inside the steel connector, and the steel fastener is pressed against the steel of the ultra-high independent stiff column by the anti-slip pad.

[0010] A lifting method using a device suitable for lifting steel formwork hanging molds for ultra-high independent stiffened columns includes the following steps:

[0011] Step 1: Fabricate steel fixing frames according to the dimensions of the ultra-high independent stiffened columns, and fabricate steel connecting parts according to the thickness of the steel profiles of the ultra-high independent stiffened columns;

[0012] Step 2: Install the steel connectors to the bottom of the steel frame using the support rods. Each steel connector corresponds to one of the web plates of the ultra-high independent stiffened column steel.

[0013] Step 3: Attach the bottom opening of the steel connector to the web of the ultra-high independent stiffened column and screw in the steel fasteners so that a pair of steel fasteners are clamped on the web of the steel from both sides.

[0014] Step 4: Install the formwork lifting equipment on the steel frame, and hang the steel formwork of the ultra-high independent stiff column on the hook of the formwork lifting equipment;

[0015] Step 5: Use the formwork lifting equipment to lift the steel formwork to the installation position, and adjust the position of the steel formwork to align it with the structure of the ultra-high independent stiffened column.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention, with its steel fixing frame, steel connectors, and steel fasteners, is designed to be installed on ultra-high independent stiffened columns. The steel connectors fasten the components to the steel web of the column, and the symmetrically arranged steel fasteners are screwed in and locked onto the steel web. This allows it to be installed on ultra-high independent stiffened columns of different shapes and sizes. It is easy and simple to assemble and disassemble, ensuring the secure and reliable installation of the entire device on the ultra-high independent stiffened column steel. This improves the stability, safety, and positional accuracy of the steel formwork lifting process and has broad application prospects.

[0018] 2. Because the present invention is equipped with a steel fixing frame and a formwork lifting device, the steel fixing frame is erected on the steel of the ultra-high independent stiff column, and the steel formwork of the ultra-high independent stiff column is stably lifted by the formwork lifting device, eliminating the need for external scaffolding, optimizing the utilization of construction space, reducing labor and material costs, and improving construction efficiency and safety.

[0029] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a device and method for lifting and hoisting steel formwork for ultra-high independent stiffened columns, as proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0030] Please see the appendix Figure 1 To be continued Figure 3 Appendix Figure 5 To be continued Figure 8 A device for lifting and hoisting steel formwork for ultra-high independent rigid columns includes a steel frame 1, formwork lifting equipment 2, support rods 3, steel connectors 4, and steel fasteners 5. The upper ends of several support rods 3 are respectively installed at the bottom of the steel frame 1, and the lower end of each support rod 3 is equipped with a steel connector 4. The steel connector 4 can be matched and snapped onto the steel of the ultra-high independent rigid column and locked and fixed by a pair of steel fasteners 5, so that the steel frame 1 is horizontally erected above the steel of the ultra-high independent rigid column. The length and width of the steel frame 1 are not less than the length and width (or diameter) of the ultra-high independent rigid column. Several formwork lifting equipment 2 are respectively spaced on the steel frame 1, so that several steel formworks 6 of the ultra-high independent rigid column are respectively hung below the hooks 21 of the several formwork lifting equipment 2, and the several steel formworks 6 can be aligned with the structure of the ultra-high independent rigid column.

[0031] The shape and size of the steel fixing frame 1 and the number of steel connecting parts 4 can be adjusted according to the size of the ultra-high independent stiffened column and the adaptability of its steel shape. Usually, the steel of the ultra-high independent stiffened column is a cross-shaped H-section steel, and the cross section of the ultra-high independent stiffened column is circular or square. The steel fixing frame 1 can be made into a cross-shaped structure with equal length and width. The steel fixing frame 1 can be made of square steel, and the specifications of the square steel are selected according to the load requirements.

[0032] The number of support rods 3 is the same as the number of steel profile connectors 4. Each steel profile connector 4 is equipped with a pair of steel profile fasteners 5, which can clamp and lock the web of the ultra-high independent stiffened column steel from both sides, thereby firmly locking the entire device onto the ultra-high independent stiffened column steel. Preferably, the steel profile connectors 4 are installed on the web of the steel profile.

[0033] The formwork lifting device 2 can be an electric hoist, a manual hoist, or other types of lifting equipment. The formwork lifting device 2 can be bolted to the steel frame 1 via a mounting plate. The steel formwork 6 is hung below the hook 21 of the electric hoist using a wire rope, facilitating its lifting to the designated height. Electric hoists and wire ropes are conventional lifting equipment in this field, and their lifting process will not be described in detail here.

[0034] The number and installation location of the formwork lifting equipment 2 can be determined according to the location and number of steel formwork 6, so as to ensure that each steel formwork 6 can be lifted safely and stably by the formwork lifting equipment 2, and that each steel formwork 6 is lifted synchronously.

[0035] The steel frame 1 is erected above the steel sections inside the ultra-high independent rigid column via steel connectors 4, eliminating the need for scaffolding and reducing construction preparation and dismantling time, labor and material costs, and significantly improving the efficiency of formwork lifting. Simultaneously, the steel frame 1, fixed to the steel sections inside the ultra-high independent rigid column, avoids the instability of external attachment structures, significantly improving the stability and wind resistance of the equipment, reducing the risks of high-altitude operations, and lowering the probability of safety accidents. Furthermore, it fully utilizes the internal space of the ultra-high independent rigid column, avoiding the need for external equipment to occupy additional space, improving the utilization rate of the construction site, and making the overall layout more flexible and adaptable to meet the needs of different construction environments.

[0036] The steel formwork 6 was lifted using the formwork lifting device 2, which ensured the rapid lifting and precise positioning of the steel formwork 6. The lifting process was continuous and automated, reducing the tediousness of manual operation. It also had good compatibility with the internal structure, improving the utilization rate and construction efficiency of the entire device and significantly shortening the construction cycle.

[0037] Please see the appendix Figure 4 The steel connector 4 is an inverted U-shaped structure with an open bottom. The closed top end of the steel connector 4 is fixedly connected to the lower end of the support rod 3. The width of the bottom opening of the steel connector 4 is greater than the thickness of the steel of the ultra-high independent stiff column, so that the steel connector 4 is snapped onto the steel of the ultra-high independent stiff column through the bottom opening and locked and fixed by a pair of steel fasteners 5.

[0038] The inverted U-shaped steel connector 4 is easy to fasten onto the steel web of the ultra-high independent stiffened column. The weight of the steel formwork 6 ensures the stability of the fastening of the steel connector 4 onto the steel web, preventing it from falling off. The opening width of the steel connector 4 is slightly larger than the thickness of the steel of the ultra-high independent stiffened column, and it can be locked and fixed to the steel web by the steel fastener 5. It can adapt to the installation on steel of different thicknesses and has high versatility.

[0039] Preferably, the support member 3 can be made of round tube, and the specifications of the round tube can be selected according to the quantity and weight of the steel formwork 6, so that the support member 3 can meet the load requirements. The steel connector 4 can be made of bent steel plate.

[0040] Please see the appendix Figure 4 The steel connector 4 has screw holes formed on both sides of its side walls, and the steel fastener 5 has a threaded section that matches the screw holes. The steel fastener 5 passes through the side wall of the steel connector 4 by rotating the thread, so that one end of a pair of steel fasteners 5 located inside the steel connector 4 can be pressed against the two surfaces of the steel of the ultra-high independent stiffness column.

[0041] By utilizing the screwing in and out of the thread between the screw hole and the threaded section, the rotation of the steel fastener 5 is converted into axial linear motion, thereby enabling a pair of steel fasteners 5 to be clamped on both sides of the web of the ultra-high independent stiffness column steel, or to release the web of the ultra-high independent stiffness column steel. The installation is firm and reliable, and the disassembly and assembly are convenient and efficient.

[0042] Please see the appendix Figure 4 The steel fastener 5 is provided with an anti-slip pad 501 on one end inside the steel connector 4, and the steel fastener 5 is pressed against the steel of the ultra-high independent stiff column by the anti-slip pad 501.

[0043] Preferably, the anti-slip pad 501 can be made of rubber, which has good anti-slip performance, increases friction, and further improves the installation stability of the entire device on the ultra-high independent stiffness column steel.

[0044] Please see the appendix Figure 1 To be continued Figure 8 A method for lifting and hoisting steel formwork for ultra-high independent stiffened columns includes the following steps:

[0045] Step 1: Fabricate steel fixing frame 1 according to the dimensions of the ultra-high independent stiffened column, and fabricate steel connecting parts 4 according to the thickness of the steel of the ultra-high independent stiffened column.

[0046] Step 2: Install the steel connector 4 to the bottom of the steel fixing frame 1 using the support rod 3. Several steel connectors 4 correspond one-to-one with several web plates of the ultra-high independent stiffened column steel.

[0047] Preferably, the steel connector 4, the support rod 3, and the steel fixing frame 1 can be initially fixed with bolts, and the connection can be further strengthened by welding after the installation position is determined.

[0048] Step 3: Attach the bottom opening of the steel connector 4 to the steel web of the ultra-high independent stiff column, and screw in the steel fastener 5 so that a pair of steel fasteners 5 are clamped on the steel web from both sides.

[0049] Specifically, a pair of steel fasteners 5 are screwed into the screw holes on both sides of the steel connector 4. The screws are rotated to vertically tighten the pair of steel fasteners 5 onto the two surfaces of the steel web, ensuring a reliable connection between the steel connector 4 and the steel, preventing loosening or slippage during the lifting of the steel formwork 6, and ensuring the safety and stability of the lifting of the steel formwork 6.

[0050] Step 4: Install the formwork lifting device 2 on the steel frame 1, and hang the steel formwork 6 of the ultra-high independent stiff column on the hook 21 of the formwork lifting device 2.

[0051] Step 5: Lift the steel formwork 6 to the installation position using the formwork lifting device 2, and adjust the position of the steel formwork 6 to align it with the structure of the ultra-high independent stiffened column.

[0052] During the lifting of the steel formwork 6, each formwork lifting device 2 operates synchronously, lifting slowly and at a consistent speed to ensure the stable and safe lifting of each steel formwork 6, and also to ensure that the steel fixing frame 1 is subjected to consistent forces in all directions. The entire device remains balanced and stable, preventing tipping.

[0053] After lifting and adjusting the steel formwork 6, fix, correct, seal and reinforce the steel formwork 6 according to the conventional installation procedure for ultra-high independent stiffened columns. Finally, pour the concrete. This is the conventional construction process for ultra-high independent stiffened columns, which will not be described in detail here.

[0054] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
