Description

Technical Field

[0001] This invention relates to the field of I-beam construction and hoisting technology, and more particularly to a hoisting method for I-beam construction. This method is mainly used for hoisting in construction processes such as assembly, turning, and transportation of steel structure I-beams. This invention belongs to the technical field of hoisting and lifting construction methods for steel structure I-beam bridges. Background Technology

[0002] Currently, the fabrication, on-site hoisting, and transportation of I-beams typically involve binding with wire ropes and using clamps. However, this method presents significant safety hazards during actual construction, primarily in two aspects: first, insecure wire rope binding can easily lead to the load falling off; second, direct contact between the wire rope and the sharp edge of the steel beam can easily result in the sharp edge cutting the wire rope. Furthermore, the use of wire ropes or clamps inevitably leaves construction marks on the steel beam surface during fabrication, affecting the product's surface quality and requiring subsequent grinding and repair. Therefore, designing and adopting a dedicated hoisting and construction method for I-beams is essential for both construction efficiency and safety. Summary of the Invention

[0003] The purpose of this invention is to provide a hoisting method for I-beam construction, solving the technical problem that existing methods of binding I-beams with wire ropes or clamps during processing, on-site hoisting, and transportation can easily result in sharp edges of the components cutting the wire ropes or leaving construction marks on the surface of the steel beam, affecting the surface quality of the product. At the same time, this method allows for rapid hoisting of I-beams. Existing hoisting methods are slow and prone to scratching or detachment.

[0004] This method can be used for hoisting operations in the assembly, turning, transporting, and installation of I-beams. It is convenient and quick, can effectively improve construction efficiency, reduce the costs of later grinding and repair, and can effectively control the appearance quality of I-beams.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A hoisting method for I-beam construction includes setting up an I-beam turning and transporting device, which is clamped onto the flange plate of the I-beam. The two ends of the I-beam turning and transporting device are provided with two buckle holes. Depending on the assembly, turning or transport of the I-beam, the corresponding buckle hole is selected for hoisting, thus completing the hoisting construction of the I-beam.

[0006] Furthermore, when the I-beam needs to be assembled, it is only necessary to select any one of the two snap-fit ​​holes for hoisting. The equipment is connected to any one of the snap-fit ​​holes to lift the I-beam, and then the I-beam assembly process is carried out. Furthermore, when the I-beam needs to be turned over, select the buckle hole opposite to the turning direction, and then use the equipment to connect to the corresponding buckle hole. With the help of the workshop crane's auxiliary hook or another hoisting equipment, the turning of the component can be completed. Furthermore, when the I-beam needs to be transferred, two locking holes should be selected simultaneously to ensure hoisting stability. The equipment should be connected to both locking holes at the same time, and then the I-beam should be hoisted. Furthermore, the I-beam turning and transporting device includes two main structures, turnbuckles, telescopic plate devices, and contour positioning devices. The main structures are set as flat L-shaped structures, and the two main structures are respectively connected to both ends of the turnbuckles. The telescopic plate devices are telescopically connected to the main structures. The contour positioning devices are set by pressing the flange plates of the I-beams through the main structures or the telescopic plate devices. Both ends of the main structures are provided with snap-fit ​​holes.

[0007] Furthermore, the main structure includes a main rod and a hook body. The hook body is integrally formed with the main rod. The horizontal plate at the bottom of the hook body is balanced with the main rod. The hook body and the main rod form an I-beam flange plate groove, and the I-beam flange plate is set in the I-beam flange plate groove.

[0008] Furthermore, a sliding groove is provided on the bottom horizontal plate of the hook body. The sliding groove is designed with a concave structure, and several bolt holes are provided on the outer side of the sliding groove.

[0009] Furthermore, the telescopic flat plate device includes a reinforcing plate, a telescopic horizontal plate, and a retaining shaft. One end of the reinforcing plate is set on the telescopic horizontal plate and extends out of the outer end of the telescopic horizontal plate. One end of the retaining shaft is connected to one end of the telescopic horizontal plate. The retaining shaft is set at the bottom of the reinforcing plate extending out of the telescopic horizontal plate and is fitted into a sliding groove. The reinforcing plate is provided with several spaced fixing bolt holes, and bolts are used to fix the telescopic flat plate device to the main structure.

[0010] Furthermore, the contour positioning device includes a first contour positioning rod, which is disposed on the hook body and passes through the hook body to press the flange plate of the I-beam.

[0011] Furthermore, the contour positioning device also includes a second contour positioning rod, which is disposed on the telescopic horizontal plate and passes through the telescopic horizontal plate to press against the flange plate of the I-beam. The second contour positioning rod is disposed to move with the telescopic horizontal plate as it extends and retracts.

[0012] The present invention, by adopting the above-described technical solution, has the following beneficial effects: (1) The present invention can be telescopic and can hoist I-beam flange plates of different thicknesses or different widths; in addition, the device is equipped with a contour positioning rod, which can effectively ensure the relative stability between the device and the I-beam members and avoid damage such as scratches on the surface of the components due to hoisting. The device is convenient and practical in the production process of I-beams and effectively reduces the grinding and repair costs caused by the appearance quality problems such as scratches in the later stage.

[0013] (2) The telescopic plate device is set as a telescopic and detachable structure, which can be quickly installed into the I-beam, avoiding slow installation efficiency, and can also meet the hoisting of I-beams of different sizes when passing through. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the present invention, and these aspects of the invention can be implemented even without these specific details.

[0017] like Figure 1-5As shown, a hoisting method for I-beam construction includes an I-beam turning and transporting device. This device clamps onto the flange of the I-beam and has two locking holes 3 at each end. Depending on whether the I-beam needs to be assembled, turned, or transported, the appropriate locking hole 3 is selected for hoisting, thus completing the hoisting process. When the I-beam needs to be assembled, only one of the two locking holes 3 needs to be selected for hoisting. Equipment is connected to either locking hole 3 to lift the I-beam, and then the assembly process can proceed. When the I-beam needs to be turned, the locking hole 3 opposite to the turning direction is selected. Equipment is then connected to the corresponding locking hole 3, and in conjunction with the workshop crane's auxiliary hook or another hoisting device, the turning operation can be completed. When the I-beam needs to be transported, both locking holes 3 must be selected simultaneously to ensure hoisting stability. Equipment is connected to both locking holes 3 at the same time, and then the I-beam is hoisted. The I-beam turning and transport device includes two main structures 1, turnbuckles 2, a telescopic plate device, and a contour positioning device. The main structures 1 are designed as a horizontal L-shaped structure. The two main structures 1 are connected to both ends of the turnbuckles 2. The telescopic plate device is telescopically connected to the main structures 1. The contour positioning device passes through the main structures 1 or the telescopic plate device and presses against the flange of the I-beam. The ends of the main structures 1 are equipped with snap-fit ​​holes 3. The turnbuckles 2 are O-type turnbuckles. The main structures 1 are the primary load-bearing structures for hoisting. The main structures 1 and turnbuckles 2 are fixed together by welding, ensuring the device's stability.

[0018] like Figure 1 As shown, the main structure 1 includes a main rod and a hook body. The hook body is integrally formed with the main rod. The horizontal plate at the bottom of the hook body is balanced with the main rod. The hook body and the main rod form an I-beam flange plate groove 4, and the I-beam flange plate is set in the I-beam flange plate groove 4. A sliding groove 6 is provided on the bottom horizontal plate of the hook body. The sliding groove 6 is a concave structure, and several bolt holes are provided on the outer side of the sliding groove 6.

[0019] The telescopic flat plate device includes a reinforcing plate 8, a telescopic horizontal plate 10, and a retaining shaft 11. One end of the reinforcing plate 8 is set on the telescopic horizontal plate 10 and extends out of the outer end of the telescopic horizontal plate 10. One end of the retaining shaft 11 is connected to one end of the telescopic horizontal plate 10. The retaining shaft 11 is set at the bottom of the reinforcing plate 8 extending out of the telescopic horizontal plate 10. The retaining shaft 11 is fitted into the sliding groove 6. The reinforcing plate 8 is provided with a number of spaced fixing bolt holes 9. The telescopic flat plate device is fixed to the main structure 1 using bolts.

[0020] The contour positioning device includes a first contour positioning rod 5, which is disposed on the hook body and passes through the hook body to press the flange plate of the I-beam.

[0021] The contour positioning device also includes a second contour positioning rod 7, which is disposed on the telescopic horizontal plate 10 and passes through the telescopic horizontal plate 10 to press the flange plate of the I-beam. The second contour positioning rod 7 is disposed as the telescopic horizontal plate 10 telescopically moves. Tooling devices that enable rapid assembly, convenient transportation, and easy hoisting while effectively protecting the appearance quality of components are convenient, quick, and effectively improve construction efficiency, reducing the costs associated with subsequent grinding and repair.

[0022] Before use, loosen the bolts on the fixing bolt holes 9 appropriately, slide the telescopic horizontal plate 10 horizontally out, and then loosen the turnbuckle bolts 2 so that the distance between the horizontal plates at the bottom of the two hooks is greater than the width of the I-beam flange plate to be hoisted. Then place the hooks on both sides of the I-beam flange plate and tighten the turnbuckle bolts 2 so that the edge of the I-beam flange plate is inserted into the I-beam flange plate groove 4 of the hook. Then reinstall the telescopic horizontal plate 10, insert the retaining shaft 11 into the sliding retaining groove 6, set the customized position according to the width of the I-beam flange plate, and then use bolts to fix it horizontally to the hook through the fixing bolt holes 9. Then adjust the second contour positioning rod 7 and the first contour positioning rod 5 to press the I-beam flange into contact with the inner side of the upper main rod.

[0023] The adjusted telescopic I-beam turning and transporting device is directly hooked onto the flange plate of the I-beam to be hoisted. Then, the second contour positioning rod 7 and the first contour positioning rod 5 are adjusted according to the different thicknesses of the flange plate to ensure that the device is relatively fixed and stable with respect to the flange of the I-beam. This completes the telescopic adjustment work before hoisting.

[0024] The fabrication process of the device includes the following: 1. Cut two snap-fit ​​holes evenly at each end of the main structure of the lifting device to facilitate effective connection between the lifting devices during subsequent lifting. 2. Install retractable turnbuckles between the main structures to facilitate the use of lifting equipment to accommodate I-beams of different sizes during subsequent construction. 3. First, refer to the construction drawings and component dimensions to preliminarily determine the length of the lifting device. Then, based on the idea of ​​adding 200mm to each end of the component's external dimensions, determine the length of the main structure of the lifting device. 4. Sliding contour positioning grooves are provided at the bends of the main structure of the lifting device to meet adjustment needs; 5. At the bends in the main structure of the lifting device, extendable contour positioning rods (long bolts) are installed to ensure effective fixation between the lifting device and the I-beam, reducing potential appearance quality issues such as scratches and bumps during the lifting process.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
