Description

Technical Field

[0001] This invention relates to a hyperboloid square tubular space frame. Background Technology

[0002] Currently, most mesh structures on the market are woven from filamentous materials such as iron wire, stainless steel wire, and rope, primarily used for highway and railway protective fencing, balcony fencing, window and door security, and construction site safety and fall prevention. They cannot simultaneously meet the requirements of both decorative and maintenance components, and lack a strong three-dimensional effect, making them unsuitable for curtain wall and interior decoration projects. Furthermore, integral molding of the entire mesh frame is impossible, especially for curved structures, as existing stainless steel pipes cannot be stretched bidirectionally while maintaining a smooth surface. Summary of the Invention

[0003] This invention proposes a hyperboloid square tubular space frame, which divides the space frame into standard unit blocks, which facilitates standardized production and improves processing accuracy. It also facilitates installation and reduces on-site welding and polishing operations. The standard unit blocks are cut from three-dimensional curved surfaces and then undergo initial shaping, correction, and final shaping, making them suitable for various curved surface shapes. This invention also solves the problem of maintaining surface flatness even when subjected to bidirectional bending.

[0038] To more clearly illustrate the implementation of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and examples. The specific examples described herein are merely for explaining the content of the present invention and are not intended to limit the implementation of this invention.

[0039] Example 1

[0040] like Figure 1 As shown, the hyperboloid square tubular space frame in this embodiment includes: a plurality of standard unit space blocks 100 and at least one horizontal substrate 200.

[0041] Each standard unit block 100 includes: two inner ring square tubes 110 and two outer ring square tubes 120, such as... Figure 1 As shown.

[0042] The two inner square tubes 110 have the same structure, consisting of an inner upper curved surface 111, an inner lower curved surface 112, an inner inner end face 113, and an inner outer end face 114.

[0043] The inner ring upper curved surface 111, inner ring lower curved surface 112, inner ring inner end face 113, and inner ring outer end face 114 are cut into materials using a laser cutting machine based on the graphics exported from the design model. This ensures that the material accuracy of each pipe fitting on all four sides is controlled within ±0.01mm. The four sides of the sheet metal are then welded together to form a standard pipe fitting. This method effectively solves the problem that finished stainless steel pipes cannot be bent in both directions.

[0044] like Figure 2As shown, the inner end face 113 and the outer end face 114 of the inner ring are wavy. The length of the outer end face 114 is slightly longer than that of the inner end face 113. The upper curved surface 111 and the lower curved surface 112 of the inner ring have the same dimensions. The inner curvature of the upper curved surface 111 and the lower curved surface 112 of the inner ring is consistent with the curvature set in the hyperboloid square tubular space frame. The outer curvature is equal to the inner curvature of the inner end face 113 of the inner ring plus the width of the upper curved surface 111 of the inner ring. After cutting, the upper curved surface 111 and the lower curved surface 112 of the inner ring curl into the corresponding wavy shape; the inner end face 113 and the outer end face 114 of the inner ring bend into the corresponding curvature arc.

[0045] When the inner ring upper curved surface 111, inner ring lower curved surface 112, inner ring inner end face 113, and inner ring outer end face 114 are assembled into the inner ring square tube 110, they are first fixed by argon arc welding with spot welding, one fixing point every 10 cm. After shaping, an inner square tube template is placed for correction. The inner square tube template ensures the curvature of the inner end face 113 of the inner ring and the shape of the wave on the upper or lower curved surface of the inner ring. Then, a laser cold welding gun is used for full welding and shaping. To minimize thermal expansion and contraction deformation, a skip welding method is adopted for full welding, skip welding every 10 cm and then turning to weld the other side. This welding method helps to minimize thermal expansion and contraction deformation and ensure the perfect curvature of the tube. For polishing, an angle grinder is used to first use a 320-grit abrasive wheel to polish the weld scars, then a 1000-grit abrasive wheel for initial polishing, and finally a wool wheel and a special wool wheel mirror polishing wax to polish to an 8K mirror finish.

[0046] Similarly, the two outer square tubes 120 have the same structure, consisting of an upper curved surface 121, a lower curved surface 122, an inner end face 123, and an outer end face 124. The two outer square tubes 120 are manufactured in the same way as the two inner square tubes 110, using a laser cutting machine to cut the material according to the modeled graphic. They are first spot-welded and fixed, then placed in a template for correction after shaping, and finally fully welded and polished.

[0047] Of course, the inner curvature of the outer upper surface 121 and the outer lower surface 122 is consistent with the outer curvature of the inner upper surface 111 and the inner lower surface 112. The outer curvature of the outer upper surface 121 and the outer lower surface 122 = the inner curvature of the outer upper surface 121 + the width of the outer upper surface 121.

[0048] In this embodiment, the two inner square tubes 110 are welded together at their ends, and the two outer square tubes 120 are welded together in the middle. After the ends of the two inner square tubes 110 and the two outer square tubes 120 are aligned, they are welded together at the intersection to form a shape as shown. Figure 1 The structure shown.

[0049] The horizontal substrate 200 can be a single-layer substrate or a square tube substrate. It is composed of several sector-shaped plates. In this embodiment, the horizontal substrate 200 is composed of several sector-shaped plates 210 forming a circular or arc-shaped structure, such as... Figure 6 As shown, the sector-shaped plates are also cut and welded together using a laser cutting machine based on the graphics exported from the design model.

[0050] Several standard unit grid blocks 100 and several sector plates 210 are manufactured in the factory and then transported to the site.

[0051] According to the design, the fan-shaped plate 210 is fixed to the corresponding position on the keel of the building by welding or other means, and the beginning and end are welded with circular or arc-shaped structures to form a horizontal base plate 200. According to the height of the hyperboloid square tubular space frame, a corresponding number of horizontal base plates 200 are set to achieve the required support strength.

[0052] Then, starting from the bottom layer, install the first ring of standard unit mesh blocks 100, and spot weld them together end to end, ensuring that the intersections form a circle. After the first layer is installed, install the second layer of the mesh frame, and so on. When reaching the horizontal base plate 200, weld at the intersection with the horizontal base plate 200 at that position; continue until the set height is reached. Finally, check the installed mesh frame for any deviations exceeding the required range. If there are no deviations, perform full welding at the joints and polish until the weld seams are invisible on the final product. Figure 7 As shown.

[0053] The construction method for hyperboloid square tubular space frame includes the following steps:

[0054] Step A: Prefabricate standard unit mesh blocks 100.

[0055] Step A-1: ​​Prepare the inner square tube 110.

[0056] Step A-1-1: Based on the graphics exported from the design model, laser cut the inner ring upper curved surface 111, inner ring lower curved surface 112, inner ring inner end face 113, and inner ring outer end face 114.

[0057] Step A-1-2: Then, perform the first spot welding on the above-mentioned plates to form a pipe fitting.

[0058] Step A-1-3: Place the spot-welded pipe fittings on the inner square tube template for alignment.

[0059] Step A-1-4: Use a laser cold welding gun to perform full welding and finally shape it into an inner square tube 110.

[0060] Step A-2: Prepare the outer ring square tube 120.

[0061] Step A-2-1: Based on the graphics exported from the design model, laser cut the outer ring upper curved surface 121, outer ring lower curved surface 122, outer ring inner end face 123, and outer ring outer end face 124.

[0062] Step A-2-2: Then, perform the first spot welding on the above-mentioned plates to form a pipe fitting.

[0063] Step A-2-3: Place the spot-welded pipe fittings on the outer square tube template for alignment.

[0064] Step A-2-4: Use a laser cold welding gun to perform full welding and finally shape it into an outer square tube of 120.

[0065] Steps A-1 and A-2 are not sequential.

[0066] Step A-3: Weld the two inner square tubes 110 at their ends to secure them, and weld the two outer square tubes 120 in the middle to secure them. After aligning the ends of the two inner square tubes 110 and the two outer square tubes 120, weld them together at the intersection.

[0067] Step B: Prepare the sector plate 210 of the horizontal substrate 200.

[0068] The fan-shaped plates are cut and welded together in a laser cutting machine based on the graphics exported from the design model.

[0069] Steps A and B are not in any particular order.

[0070] Step C: The sector plate 210 is fixed to the corresponding position on the keel of the building, and the beginning and end are welded with circular or arc-shaped structures to form a horizontal base plate 200.

[0071] Step D: Starting from the bottom layer, install the first layer of standard unit mesh blocks 100, and spot weld them together end to end. After the first layer is installed, install the second layer of standard unit mesh blocks 100, and so on. When reaching the horizontal substrate 200, weld at the intersection with the horizontal base layer 200 at that position; until the set height is reached.

[0072] Step E: Check whether the installed hyperboloid square tubular space frame has any deviations exceeding the set range. If it does not exceed the range, perform full welding at the welding joints and polish.

[0073] Example 2

[0074] If a hyperboloid square tubular space frame is installed outdoors without a structural joist as a fixed support, several 300mm columns should be added, such as... Figure 6 As shown. The other structures are exactly the same as in Embodiment 1.

[0075] According to the setup, the bottom of the column 300 is anchored to the ground at the corresponding location, and the horizontal base plate 200 is fixed to the column 300. Then, the standard unit grid block 100 is welded and fixed to the horizontal base plate 200 in the same way.

[0076] Of course, the hyperboloid square tubular space frame in this embodiment is also applicable when the horizontal base plate 200 is fixed on the building keel, but the strength is insufficient, such as when the floor height is too large.

[0077] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
