Description

Technical Field

[0001] This invention relates to the fields of complex roof system construction, complex space ceiling construction, and large-area irregular-shaped curtain wall construction technology, and in particular to a prefabrication and assembly tool for irregular-shaped components based on modular adjustable three-dimensional positioning. Background Technology

[0002] As people's demands for building functionality and aesthetics continue to increase, more and more architectural designs are becoming bolder and more innovative, especially in the field of large public buildings, where numerous complex roof systems, multi-curved ceilings, and large-area irregular facades are being designed. To achieve the design effect, prefabrication and assembly of irregular components are often used on-site, resulting in the need to fabricate and install a large number of irregular components. Existing fabrication methods typically involve several workers working together, equipped with various small tools such as protractors, tape measures, calipers, and temporary fixing clips. Taking the connection of two non-intersecting rods as an example, usually one rod is fixed first, the first person measures the angle between the second rod and the first rod and temporarily clamps the angle, the second person measures the distance and clamps it, and then a third person welds it in place. If the component requires the assembly of a large number of rods, it leads to excessive procedures and manpower, low efficiency, and is prone to construction errors, making it difficult to meet the required construction quality and affecting the normal progress of subsequent construction procedures.

[0003] Therefore, it is necessary to propose a modular adjustable three-dimensional positioning prefabrication and assembly tool for irregularly shaped components to address the above problems. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a modular adjustable three-dimensional positioning prefabrication and assembly tool for irregularly shaped components to solve the above problems.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0020] like Figure 1 and combined Figures 2 to 14 As shown, a modular adjustable three-dimensional positioning prefabrication and assembly tool for irregularly shaped components includes a support rod 1, an angle-adjusting cylinder 2, and a sliding rod 3. The angle-adjusting cylinder 2 is connected to the support rod 1, and the sliding rod 3 is connected to the support rod 1.

[0021] Furthermore, the support rod 1 includes a bottom support rod 11, a top support rod 12, a lower support rod 13, and an upper support rod 14. The bottom support rod 11 is connected to the lower support rod 13 through an angle adjusting cylinder 2. The lower support rod 13 is connected to the upper support rod 14 through a sliding rod 3. The upper support rod 14 is connected to the top support rod 12 through an angle adjusting cylinder 2.

[0022] The further technical solution offers several advantages: The support rod 1 is subdivided into a bottom support rod 11, a top support rod 12, a lower support rod 13, and an upper support rod 14. These parts are connected via an angle-adjustable cylinder 2 and a sliding rod 3, further refining the tool's structure and making its adjustment more targeted. This segmented design allows each support rod to be independently adjusted according to the specific shape and size of the irregular component, improving the tool's adaptability to different irregular components and enhancing the accuracy of three-dimensional positioning.

[0023] Furthermore, both the bottom support rod 11 and the top support rod 12 are wide and flat cuboids. Each of the bottom support rod 11 and the top support rod 12 has a pair of first protrusions 15 in the middle, and a first circular hole 151 in the middle of the first protrusions 15. Each of the bottom support rod 11 and the top support rod 12 has a pair of second protrusions 16 at one end, and a second circular hole 161 in the middle of the second protrusions 16. An arc groove 17 matching the angle adjustment cylinder 2 is provided between the pair of second protrusions 16.

[0024] The adoption of further technical solutions offers several advantages: the bottom support rod 11 and top support rod 12, with their wide and flat cuboid shape, provide a more stable support foundation. The first convex plate 15 and its central first circular hole 151, the second convex plate 16 and its central second circular hole 161, and the arc-shaped groove 17 provide precise installation positions for connections with other components, ensuring the stability and reliability of the connection. Simultaneously, the matching design of the arc-shaped groove 17 with the angle adjusting cylinder 2 facilitates the installation of the angle adjusting cylinder 2 and the angle adjustment operation, improving the convenience of tool adjustment.

[0025] Furthermore, both the lower support rod 13 and the upper support rod 14 are hollow cuboids. Both the lower support rod 13 and the upper support rod 14 have a sliding groove 18 on one side. One end of the lower support rod 13 and the upper support rod 14 is sealed and is an arc shape that matches the angle adjustment cylinder 2. The other end of the lower support rod 13 and the upper support rod 14 is a through design.

[0026] The further technical solution offers several advantages: the lower support rod 13 and upper support rod 14 are hollow cuboids, reducing the overall weight of the tool while maintaining structural strength. The slide groove 18 provides a track for the sliding adjustment of the slide rod 3, making its movement smoother and more stable. The closed, arc-shaped design at one end matches the angle adjustment cylinder 2, ensuring a tight connection and effective angle adjustment. The through design at the other end facilitates the nesting connection of other components, enhancing the tool's structural compactness and adjustment flexibility.

[0027] Furthermore, the angle adjusting cylinder 2 includes a lower angle adjusting cylinder 21 and an upper angle adjusting cylinder 22. Both the lower angle adjusting cylinder 21 and the upper angle adjusting cylinder 22 are provided with angle scale lines at both ends. Both the lower angle adjusting cylinder 21 and the upper angle adjusting cylinder 22 are provided with knobs 23 at both ends. The knobs 23 pass through the second circular hole 161.

[0028] The further technical solution offers the following benefits: The angle adjusting cylinder 2 is divided into a lower angle adjusting cylinder 21 and an upper angle adjusting cylinder 22. The angle scale lines at both ends provide a clear reference for angle adjustment, allowing operators to precisely control the adjustment angle and improving positioning accuracy. The design of the knob 23 passing through the second circular hole 161 facilitates the operator's fixing and adjustment of the angle adjusting cylinder 2, ensuring the stability of the structure after angle adjustment and preventing the assembly accuracy of components from being affected by angle deviation during assembly.

[0029] Furthermore, the lower angle adjusting cylinder 21 is embedded in the arc groove 17 of the bottom support rod 11, the arc-shaped end of the lower support rod 13 is connected to the lower angle adjusting cylinder 21, the upper angle adjusting cylinder 22 is embedded in the arc groove 17 of the top support rod 12, and the arc-shaped end of the upper support rod 14 is connected to the upper angle adjusting cylinder 22.

[0030] The benefits of adopting a further technical solution are as follows: This connection method makes the connection between the angle adjustment cylinder and the support rod more stable, the force is more even during angle adjustment, reduces shaking and deviation during the adjustment process, and further improves the accuracy of angle adjustment and the overall stability of the tool.

[0031] Furthermore, the slide bar 3 includes a lower slide bar 31, an upper slide bar 32, a first scale slide bar 33, and a second scale slide bar 34. The two ends of the lower slide bar 31 are connected to the bottom support rod 11 and the lower support rod 13, respectively. The two ends of the upper slide bar 32 are connected to the top support rod 12 and the upper support rod 14, respectively. The first scale slide bar 33 and the second scale slide bar 34 are each provided with scale lines on one side. The first scale slide bar 33 is a hollow structure and is sleeved on the hollow part of the lower support rod 13. The two ends of the second scale slide bar 34 are respectively sleeved on the hollow parts of the first scale slide bar 33 and the upper support rod 14.

[0032] The further technical solution offers the following benefits: the slide bar 3 is further refined into a lower slide bar 31, an upper slide bar 32, a first-scale slide bar 33, and a second-scale slide bar 34. The lower slide bar 31 and the upper slide bar 32 connect the bottom support rod 11 to the lower support rod 13 and the top support rod 12 to the upper support rod 14, respectively, enhancing the linkage between the various parts. The scale lines on the first-scale slide bar 33 and the second-scale slide bar 34 provide a precise measurement reference for length adjustment, facilitating accurate control of the adjustment length by the operator. The first-scale slide bar 33 is fitted into the hollow part of the lower support rod 13, and the second-scale slide bar 34 is fitted into the hollow parts of the first-scale slide bar 33 and the upper support rod 14. This nested structure makes the tool's length adjustment more flexible, enabling a wide range of length changes and adapting to the assembly needs of irregularly shaped components of different sizes.

[0033] Furthermore, each of the lower sliding rod 31 and the upper sliding rod 32 is provided with a slider 35 at one end. The slider 35 of the lower sliding rod 31 is slidably connected to the groove 18 of the lower support rod 13, and the slider 35 of the upper sliding rod 32 is slidably connected to the groove 18 of the upper support rod 14. Each of the other ends of the lower sliding rod 31 and the upper sliding rod 32 is provided with a roller 36. The roller 36 of the lower sliding rod 31 is tumbledly connected to the first round hole 151 of the bottom support rod 11, and the roller 36 of the upper sliding rod 32 is tumbledly connected to the first round hole 151 of the top support rod 12.

[0034] The further technical solution offers the following benefits: This sliding and rolling connection reduces frictional resistance between components, making the adjustment of the slide bar smoother and less strenuous, and facilitating quick position adjustments by the operator. Simultaneously, the design of the slider 35 and roller 36 ensures the stability and accuracy of the slide bar during adjustment, preventing jamming and offset, and further improving the accuracy of the tool's three-dimensional positioning and operational efficiency.

[0035] Compared with the prior art, the present invention has the following advantages: The wide and flat rectangular shape of the bottom support rod 11 and the top support rod 12 in the support rod 1, along with the design of the first convex plate 15 and the second convex plate 16, combined with the hollow structure of the lower support rod 13 and the upper support rod 14 and the sliding groove 18, provides a stable support foundation for the whole; the angle adjustment cylinder 2, with its lower angle adjustment cylinder 21 and upper angle adjustment cylinder 22, has angle scale lines and knobs 23, which, in conjunction with the fitting of the arc groove 17, achieve precise control of the component assembly angle; the slider 35 and roller 36 design of the lower slide rod 31 and the upper slide rod 32 in the slide rod 3, as well as the scale lines and nested structure of the first scale slide rod 33 and the second scale slide rod 34, can achieve precise positioning in three dimensions. The overall modular design allows the tool to flexibly adapt to different irregularly shaped components, greatly improving the accuracy and efficiency of prefabrication and assembly, and reducing the difficulty of construction.

[0036] Working principle: Taking the connection of two simple, non-intersecting rods as an example of an irregularly shaped component: First, using the fixed first rod as a reference, position the bottom support rod 11 against it. Adjust the knob 23 of the lower angle adjusting cylinder 21 to adjust the angle between the lower support rod 13 and the bottom support rod 11 according to the required angle, and then fix it. Simultaneously, adjust the overall length using the scale lines of the first scale slide rod 33 and the second scale slide rod 34. If insufficient, extend it using the nesting structure until it matches the required spacing between the two rods. Simultaneously adjust the knob 23 of the upper angle adjusting cylinder 22 to adjust the angle between the top support rod 12 and the upper support rod 14, ensuring the angle between the bottom support rod 11 and the top support rod 12 is... After the two rods are fixed at the designed angle, the sliding rod 31 slides along the groove 18 of the lower support rod 13 via the slider 35, and the roller 36 rolls in the first round hole 151 of the bottom support rod 11. The upper sliding rod 32 slides along the groove 18 of the upper support rod 14 via the slider 35, and the roller 36 rolls in the first round hole 151 of the top support rod 12, forming a stable support structure. Finally, the second rod is placed on the top support rod 12 and fixed. By repeating the above adjustment process, the positioning, fabrication and installation of various irregular components can be completed at any reference position without reference.

[0037] Example 1: Assembly Example of Irregular Support Frame for Building Curtain Wall Based on Modular Adjustable 3D Positioning Tool I. Implementation Scenarios and Component Parameters This embodiment is applied to the assembly of irregular support frames for building curtain wall facades. It requires the three-dimensional positioning and assembly of two non-intersecting aluminum alloy support members (component A and component B) to form the irregular turning nodes of the curtain wall keel. Specifically: Component A: 6061-T6 aluminum alloy square tube, with a cross-sectional size of 100mm×100mm and a length of 2000mm. It has been fixed to the main structure of the building through embedded parts and serves as the assembly reference component. Its axis is inclined at a 30° angle to the building facade. Component B: 6061-T6 aluminum alloy square tube, with a cross-sectional size of 80mm×80mm and a length of 1800mm. It needs to form a spatial irregular node with component A. The design requirements are: the axes of the two components do not intersect in space, the vertical distance (spacing) is 500mm, the included angle of the axes is 120°, and both ends of component B need to be precisely connected to the adjacent keel.

[0038] II. Preparations before tool assembly Component Inspection and Assembly: Confirm that all components of the modular adjustable 3D positioning tool are intact. Assemble the following components: bottom support rod 11 (wide, flat cuboid, 800mm long, first protrusion 15 with a spacing of 150mm, second protrusion 16 with a circular groove 17 of 50mm radius), lower support rod 13 (hollow cuboid, 60mm x 60mm cross-section, slide groove 18 with a length of 400mm), upper support rod 14 (same specifications as lower support rod 13), and top support rod 12 (same specifications as bottom support rod 11). The initial connection is completed by using the angle adjustment cylinder 2 (lower angle adjustment cylinder 21, upper angle adjustment cylinder 22, length 120mm, angle scale line accuracy at both ends 0.5°, knob 23 diameter 12mm) and the slide bar 3 (lower slide bar 31, upper slide bar 32 length 500mm, first scale slide bar 33 hollow section 50mm×50mm, scale accuracy 1mm, second scale slide bar 34 section 45mm×45mm) to ensure that the movement of each component is smooth and without jamming.

[0039] Reference calibration: Use a laser line projector to calibrate the axial position and tilt angle of component A, and mark three positioning reference lines parallel to the axis on the surface of component A with a spacing of 100mm (matching the width of the bottom support rod 11) to ensure that the bottom support rod 11 can be accurately aligned with the axis of component A after it is attached.

[0040] III. Step-by-step assembly and adjustment process (a) Positioning of reference components and fixing of tools The wide, flat surface of the bottom support rod 11 is tightly fitted to the positioning reference line of component A. A bolt is inserted through the first round hole 151 of the first protrusion plate 15, and the bottom support rod 11 is rigidly fixed to component A with the help of a buckle. This ensures that the axis of the bottom support rod 11 is completely parallel to the axis of component A, with the error controlled within ±0.5mm, providing a stable reference for subsequent adjustments.

[0041] (ii) Adjustment of the angle and length of the lower support rod Angle Adjustment: The operator rotates the knobs 23 at both ends of the lower angle adjusting cylinder 21 to rotate the lower angle adjusting cylinder 21 along the arc groove 17 of the bottom support rod 11 (the gap between the arc groove 17 and the lower angle adjusting cylinder 21 is ≤0.2mm to ensure adjustment stability). Referring to the angle scale line at the end of the lower angle adjusting cylinder 21, the included angle between the lower support rod 13 and the bottom support rod 11 is adjusted to 60° (because the included angle between the axes of component A and component B is 120°, according to the spatial geometry, the included angle between the lower support rod and the bottom support rod needs to be matched as a supplementary angle). After the adjustment is completed, the knobs 23 are tightened, and the second hole 161 of the second protruding plate 16 is engaged with the thread of the knob 23 to achieve locking. At this time, the spatial angle error between the axis of the lower support rod 13 and the axis of component A is ≤0.3°.

[0042] Length adjustment: Pull the first scale slide bar 33 (the hollow structure is fitted into the hollow part of the lower support rod 13), and refer to its surface scale lines to adjust the combined length of the lower support rod 13 and the first scale slide bar 33 to 400mm; then pull the second scale slide bar 34 (one end is fitted into the hollow part of the first scale slide bar 33, and the other end is fitted into the hollow part of the upper support rod 14) to supplement the overall length to 500mm (consistent with the design spacing of components A and B). During the adjustment process, the sliding groove 18 of the first scale slide bar 33 and the lower support rod 13 slides smoothly without deviation, and the length error is controlled within ±1mm.

[0043] (III) Linkage adjustment of the upper support rod and the top support rod Angle Synchronization Adjustment: Rotate the knob 23 of the upper angle adjustment cylinder 22 to rotate the upper support rod 14 along the arc groove 17 of the top support rod 12. Referring to the angle scale line, adjust the included angle between the top support rod 12 and the upper support rod 14 to 60°. This ensures that the included angle between the axis of the top support rod 12 and the axis of the upper support rod 14 forms a symmetrical structure with the included angle between the bottom support rod 11 and the lower support rod 13, providing a positioning reference plane for component B that is parallel to component A.

[0044] Slide bar stability adaptation: While adjusting the angle of the upper support rod 14, the upper slide bar 32 slides along the groove 18 of the upper support rod 14 via the slider 35 at its end, and the roller 36 at the other end rolls in the first round hole 151 of the top support rod 12 (the gap between the roller 36 and the first round hole 151 is ≤0.1mm, and the rolling resistance is ≤5N); simultaneously, the slider 35 of the lower slide bar 31 slides along the groove 18 of the lower support rod 13, and the roller 36 rolls in the first round hole 151 of the bottom support rod 11, forming a stable support structure of "double slide bar + double roller". At this time, the overall spatial deflection of the tool is ≤2mm, which meets the high-precision positioning requirements.

[0045] (iv) Positioning and fixing of component B The bottom surface of component B is attached to the wide flat surface of the top support rod 12. Temporary fixing bolts are inserted through the first round hole 151 of the first protrusion plate 15 of the top support rod 12. The axial position of component B is adjusted so that it is parallel to the axis of the top support rod 12, and the deviation of the docking ports of both ends with the adjacent keel is ≤1mm. Then, the distance (500mm) between component B and component A and the axial angle (120°) are checked using a laser rangefinder and an angle meter. After confirming that there are no errors, component B is fixed to the top support rod 12 and the adjacent keel by welding or bolting to complete the assembly of the irregular node.

[0046] IV. Implementation Results Verification Accuracy met: Through total station testing, the actual distance between component B and component A is 500.5mm, and the included angle of the axis is 119.8°, both within the design allowable error range (±1mm, ±0.5°), meeting the high-precision assembly requirements of the curtain wall frame; Efficiency Improvement: Compared to the traditional method of repeated calibration of total stations and welding of temporary supports (which takes 4 hours per assembly), this tool achieves rapid positioning through modular adjustment, requiring only 1.5 hours per assembly, resulting in a 62.5% increase in efficiency. High adaptability: Subsequently, by replacing the slide rods of different lengths (the first scale slide rod 33 can be extended up to 800mm) and adjusting the scale of the cylinder 2, the tool successfully completed the assembly of three other irregular support frames of different specifications (spacing 300-600mm, included angle 90-150°) in this curtain wall project without the need for additional customized special tools, thus reducing construction costs.
