Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically a high-altitude assembly mechanism and method for metal structures. Background Technology

[0002] As industrial metal structure frames, pipe racks, and other installations are increasingly arranged vertically, metal structures are often divided into several sections for high-altitude assembly to ensure installation. Vertical assembly of industrial metal structures refers to the prefabrication of metal components (such as steel columns, steel beams, wind-resistant columns, and steel purlins) in a factory, followed by vertical assembly on the construction site according to design requirements. This method leverages the advantages of factory production, modular design, and standardized components, significantly shortening the construction cycle and improving construction efficiency and quality. It is widely used in various large-scale buildings and structures, such as high-rise buildings, large factories, bridges, and towers. Vertical assembly has significant advantages, especially in projects requiring rapid construction, high quality, and complex structural forms.

[0003] With the increase in the amount of high-altitude installation work, it is difficult to guarantee the installation quality, safety and efficiency. Problems such as reduced efficiency and increased safety risks often occur. The installation quality is not high, especially the verticality is difficult to control, and the misalignment and misalignment of the assembly welds are large, resulting in serious quality problems that exceed the specifications.

[0004] To address these issues, we provide a high-altitude assembly mechanism and method for metal structures. Summary of the Invention

[0005] The purpose of this invention is to address the problems in the prior art by providing a high-altitude assembly mechanism and method for metal structures.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A high-altitude assembly mechanism for a metal structure includes assembly lugs. Each assembly lug includes an upper assembly lug and a lower assembly lug installed at both ends of the metal structure. Two upper and two lower assembly lugs are symmetrically distributed on both sides of the metal structure. Each upper and lower assembly lug has bolt holes for bolt fixing. The mechanism also includes an assembly connecting plate for connecting the upper and lower assembly lugs on the lower section of the metal structure. The lower end of the connecting plate has a circular assembly fixing hole, which is bolted to the bolt holes on the upper assembly lugs. The middle section has an elongated assembly adjustment hole, and the upper end has an elongated assembly guide hole, which is bolted to the bolt holes on the lower assembly lugs. The assembly adjustment hole contains an assembly adjustment wedge for lifting the upper section of the metal structure to fine-tune the verticality of the two sections of the metal structure to be welded.

[0008] The lower section of the metal structure is provided with a column base for fixing the lower section of the metal structure at its bottom end, and a hook is provided above the upper section of the metal structure. The hook is provided with a hoisting wire rope for hoisting the upper pair of ear plates of the upper section of the metal structure.

[0009] As a further optimization of the present invention, the bottom of the lower pair of ear plates is provided with an inclined surface that matches the pair adjustment wedge.

[0010] As a further optimization of the present invention, the pairing adjustment wedge is provided with a fixing pin for limiting the movement of the pairing adjustment wedge.

[0011] As a further optimization of the present invention, it also includes a fixing ring for installing the ear plates of the assembly, the fixing ring comprising two semi-ring bodies, the two semi-ring bodies being fixed together by bolts, and a welding plate for welding to a metal structure being provided on the inner surface of one of the semi-ring bodies.

[0012] As a further optimization of the present invention, the end of the semi-ring is provided with a frame, the frame is provided with a bolt for fixing the frame to the semi-ring, the surface of the semi-ring is provided with a through hole, and the end face of the semi-ring is provided with a first through groove for the bolt to pass through and for it to move.

[0013] As a further optimization of the present invention, the frame is used to install the corresponding pair ear plates, the pair ear plates are provided with bolts for fixing, and the frame is provided with a second through groove for the bolts to pass through and for them to move.

[0014] As a further optimization of the present invention, it also includes a hammering assembly for hammering the adjusting wedge, the hammering assembly being hung on a fixing ring and including a mounting base, a hammer body rotatably disposed on the top of the mounting base, and a lever for driving the hammer body to rotate; a torsion spring is provided at the hinge between the hammer body and the mounting base, and a protractor is provided on the side of the lever for controlling the levering angle.

[0015] As a further optimization of the present invention, a bracket is fixedly provided on the side of the mounting base, and a mounting block is fixedly provided at the bottom of the bracket. The mounting block is provided with bolts for fixing and matching the first through groove.

[0016] This invention also provides a method for high-altitude assembly of metal structures, comprising the following steps:

[0017] S1. Install the upper and lower ear plates onto both ends of the metal structure, respectively.

[0018] S2. Use hooks and hoisting wire ropes to lift the upper section of the metal structure to the top of the lower section of the metal structure;

[0019] S3. Use pairing connecting plates and bolts to connect the upper pairing ear plate, the lower pairing ear plate and the pairing connecting plate. The bolts between the pairing fixing holes and the upper pairing ear plate are tightened and fixed. After tightening the bolts between the pairing guide holes and the lower pairing ear plate, loosen 2-3 threads.

[0020] S4. Insert the pairing adjustment wedge into the pairing adjustment hole, then hammer the pairing adjustment wedge to lift the upper metal structure, adjust the gap between the upper and lower metal structures, and after the adjustment is completed, use a fixing pin to fix the pairing adjustment wedge, and then tighten the bolts between the pairing guide hole and the lower pairing ear plate.

[0021] S5. Weld the upper and lower metal structures together. After welding, remove the upper lug plate, lower lug plate, connecting plate and adjusting wedge at the weld.

[0022] S6. Repeat S1-S5 to complete the high-altitude assembly and welding of multiple metal structures in sequence.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention can be used for high-altitude assembly and welding of metal devices such as metal frames, pipes, and large segmented equipment. It can realize rapid assembly and splicing between segmented metal structures, improve construction efficiency, and all auxiliary tools and materials involved can be reused, reducing construction costs. At the same time, the assembly and splicing quality is also high, avoiding misalignment and misalignment of weld seams in the metal structure assembly, and ensuring the verticality of the metal structure after high-altitude assembly.

[0025] 2. By setting a fixing ring, the present invention facilitates the installation of the upper and lower ear plates. The position and orientation of the upper and lower ear plates on the fixing ring can be freely adjusted, solving the problem that the existing upper and lower ear plates are directly welded to the surface of the metal structure, which requires high welding construction and is difficult to adjust once the welding position is deviated.

[0026] 3. This invention solves the problem of poor accuracy and difficulty in controlling the hammering force when manually hammering the adjusting wedge by setting up a hammering component. Attached Figure Description

[0038] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] Example 1

[0040] To address the issues of low efficiency in existing high-altitude assembly tooling, difficulty in quickly joining two metal structure sections 3, and inability to guarantee the quality of the assembly joints of metal structure 3, resulting in problems such as misalignment, uneven edges, and inconsistent perpendicularity in welds, please refer to [the relevant documentation / reference]. Figures 1-4This invention provides a high-altitude assembly mechanism for a metal structure, comprising assembly lugs. The assembly lugs include an upper assembly lug 1 and a lower assembly lug 2 installed at both ends of a metal structure 3. Two upper assembly lugs 1 and two lower assembly lugs 2 are provided, symmetrically distributed on both sides of the metal structure 3. Both the upper assembly lugs 1 and the lower assembly lugs 2 have bolt holes for bolt fixing. The invention also includes an assembly connecting plate 4 for connecting the upper assembly lugs 1 and the lower assembly lugs 2 on the lower section of the metal structure 3. The lower end of the assembly connecting plate 4 has a circular assembly fixing hole 401, which connects to the upper assembly lugs 1 and the lower assembly lugs 2 on the upper section of the metal structure 3. The bolt holes on the lug plate 1 are connected by bolts. The middle part is provided with a long strip-shaped assembly adjustment hole 402 and the upper part is provided with a long strip-shaped assembly guide hole 403. The assembly guide hole 403 is connected to the bolt holes on the lower assembly lug plate 2 by bolts. The assembly adjustment hole 402 is provided with an assembly adjustment wedge 5 for lifting the upper metal structure 3 to make fine adjustments to the verticality of the two metal structures 3 to be welded. The assembly adjustment wedge 5 is provided with a fixing pin for limiting the movement of the assembly adjustment wedge 5. The bottom of the lower assembly lug plate 2 is provided with an inclined surface 201 that matches the assembly adjustment wedge 5 so that the assembly adjustment wedge 5 can lift the upper metal structure 3.

[0041] Among them, the metal structure 3 can be a metal frame, pipe, segmented equipment, or other metal device. This invention can be used for high-altitude assembly and welding of metal devices such as metal frames, pipes, and segmented equipment. The rapid assembly and splicing between segmented metal structures 3 is achieved through the connection of the assembly connecting plate 4, which improves construction efficiency. The height of the upper section of the metal structure 3 is adjusted by the assembly adjusting wedge 5 to achieve high-quality splicing between segmented metal structures 3, avoid misalignment of weld seams and ensure the verticality of the metal structure 3 after high-altitude assembly.

[0042] The bottom of the lower metal structure 3 is provided with a column base 6 for fixing the lower metal structure 3. The upper metal structure 3 is provided with a hook 7 above it. The hook 7 is provided with a hoisting wire rope 8 for hoisting the upper pair of lugs 1 of the upper metal structure 3. At this time, the upper pair of lugs 1 serves as a hoisting lug.

[0043] This invention also provides a method for high-altitude assembly of metal structures, comprising the following steps:

[0044] S1. Install the upper ear plate 1 and the lower ear plate 2 at both ends of the metal structure 3, such as by welding.

[0045] S2. Use hooks 7 and hoisting wire ropes 8 to lift the upper section of metal structure 3 to the top of the lower section of metal structure 3;

[0046] S3. Using the assembly connecting plate 4 and bolts, the upper assembly ear plate 1, the lower assembly ear plate 2 and the assembly connecting plate 4 are connected together. The bolts between the assembly fixing hole 401 and the upper assembly ear plate 1 are tightened and fixed. After the bolts between the assembly guide hole 403 and the lower assembly ear plate 2 are tightened, 2-3 threads are loosened to facilitate the upward directional movement of the upper metal structure 3 during subsequent adjustments. When moving, the assembly guide hole 403 plays a guiding role.

[0047] S4. Insert the pairing adjustment wedge 5 into the pairing adjustment hole 402, then hammer the pairing adjustment wedge 5 to lift the upper metal structure 3, adjust the gap between the upper metal structure 3 and the lower metal structure 3, after the adjustment is completed, use a fixing pin to fix the pairing adjustment wedge 5 to prevent the pairing adjustment wedge 5 from moving, and then tighten the bolts between the pairing guide hole 403 and the lower pairing ear plate 2 to prevent changes in the alignment results.

[0048] S5. Weld the upper and lower metal structures 3 together. After welding, remove the upper ear plate 1, lower ear plate 2, pairing connecting plate 4 and pairing adjusting wedge 5 at the weld.

[0049] S6. Repeat S1-S5 to complete the high-altitude assembly and welding of multiple metal structure 3 sections in sequence.

[0050] Example 2

[0051] Based on Example 1, in order to address the problem that the upper lug plate 1 and the lower lug plate 2 are directly welded to the surface of the metal structure 3, requiring high welding standards and making adjustments difficult once the welding position deviates, such as... Figures 5-7 As shown, it also includes a fixing ring 9 for installing the assembly lugs. The fixing ring 9 comprises two semi-rings 901, which are fixed together by bolts. One of the semi-rings 901 has a welding plate 906 on its inner surface for welding to the metal structure 3. The fixing ring 9 is welded to the surface of the metal structure 3 by welding the welding plate 906, and then the position of the assembly lugs on the fixing ring 9 is adjusted, thereby reducing the welding construction requirements and improving the installation success rate of the assembly tooling.

[0052] The semi-ring 901 has a frame 902 at one end, and the frame 902 has a bolt for fixing the frame 902 to the semi-ring 901. The surface of the semi-ring 901 has a through hole 903, and the end face of the semi-ring 901 has a first through groove 904 for the bolt to pass through and for it to move. The first through groove 904 allows the position of the frame 902 on the semi-ring 901 to be adjusted, and the frame 902 itself can rotate under the action of the bolt.

[0053] The frame 902 is used to install the corresponding pair of lugs. The pair of lugs is provided with bolts for fixing, and the frame 902 is provided with a second through slot 905 for the bolts to pass through and move. The second through slot 905 allows the position of the pair of lugs on the frame 902 to be adjusted, and the pair of lugs themselves can rotate under the action of the bolts, thereby facilitating the adjustment of the pair of lugs of the upper and lower sections of the metal structure 3 to the same plane.

[0054] Example 3

[0055] Based on Embodiments 1 and 2, in order to facilitate the hammering assembly's alignment with the adjusting wedge 5 and improve the accuracy of the hammering assembly's alignment with the adjusting wedge 5, as follows: Figures 8-9 As shown, it also includes a hammering assembly 10 for hammering the adjusting wedge 5. The hammering assembly 10 is hung on the fixing ring 9 and includes a mounting base 1001, a hammer body 1002 rotatably mounted on the top of the mounting base 1001, and a lever 1003 for driving the hammer body 1002 to rotate. A torsion spring is provided at the hinge between the hammer body 1002 and the mounting base 1001, and a protractor 1004 for controlling the turning angle is provided on the side of the lever 1003. By turning the lever 1003, the hammer body 1002 is driven to rotate. When the lever 1003 is released, the hammer body 1002 hammers the adjusting wedge 5 under the restoring force of the torsion spring. The turning angle of the lever 1003 can be controlled by the protractor 1004, thereby precisely controlling the hammering force of the hammer body 1002 on the adjusting wedge 5, avoiding the problems of poor accuracy and inconvenience of manual hammering by workers.

[0056] A bracket 1005 is fixedly mounted on the side of the mounting base 1001, and a mounting block 1006 is fixedly mounted on the bottom end of the bracket 1005. The mounting block 1006 is provided with bolts for fixing and matching the first through groove 904. The mounting block 1006 and the bolts allow the position of the hammer assembly 10 on the fixing ring 9 to be freely adjusted. To adjust, loosen the bolts, move the mounting block 1006 to the desired position, adjust the orientation of the mounting block 1006, and then tighten the bolts.

[0057] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
