[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1 According to a first aspect of the present invention, a composite steel structure building includes at least one core tube steel column 100, at least two rows of outer frame steel columns 200, and at least two layers of steel trusses 300. The core tube steel column 100 is vertically arranged. The outer frame steel column 200 includes at least two longitudinally connected irregular steel columns 210, which are vertically arranged. Adjacent irregular steel columns 210 are connected to form a W shape. All outer frame steel columns 200 are arranged laterally at intervals. At least two rows of outer frame steel columns 200 are provided with a core tube steel column 100 in the middle position between them. All steel trusses 300 are arranged vertically at intervals. Each layer of steel trusses 300 is connected to all irregular steel columns 210 and all core tube steel columns 100.

[0023] The core tube steel columns 100 provide core support for the corresponding area of ​​the building, while the outer frame steel columns 200 surrounding the core tube steel columns 100 provide peripheral support for the corresponding area, thereby effectively improving the overall strength of the steel structure building and meeting the design requirements of ultra-large-scale steel structure buildings. Specifically, two adjacent irregularly shaped steel columns 210 of the outer frame steel columns 200 are connected in a W-shape, allowing the outer frame steel columns 200 to distribute support for the steel trusses 300, while the core tube steel columns 100 centrally support the steel trusses 300. The core tube steel columns 100 can be designed to be larger in size but fewer in number. Therefore, the combination of the core tube steel columns 100 and the outer frame steel columns 200 can provide sufficient support for a wider area, while reducing the overall number of supporting steel columns, saving building space, and reducing construction work.

[0024] According to some embodiments of the present invention, between two adjacent steel trusses 300, at least one suspended layer 400 is suspended on the upper steel truss 300. Compared to the steel trusses 300, the suspended layer 400 requires fewer on-site welds and is easier to install. Both the steel trusses 300 and the suspended layer 400 can be used as floors. Therefore, by setting a suspended layer 400 between two adjacent steel trusses 300, fewer steel trusses 300 are required for the same number of floors, reducing construction difficulty, improving construction efficiency, saving interior building space, and resulting in higher overall building strength and seismic performance.

[0025] In addition, the shapes and sizes of the various hanging layers 400 and steel trusses 300 can be different, so that the overall shape of the building becomes non-rectangular, making the design more novel and easier to form a landmark building.

[0026] In the specific implementation process, between two adjacent steel trusses 300, the lower steel truss 300 is connected to the hanging layer 400. This allows the lower steel truss 300 to be hoisted to the upper steel truss 300, thus connecting each layer of steel trusses 300 and each layer of hanging layer 400 into a whole, further improving the overall strength and seismic performance of the building.

[0027] According to some embodiments of the present invention, the irregular steel column 210 includes a bifurcated column 211 and two inclined columns 212. The upper ends of each bifurcated column 211 are provided with two connecting portions 211a at an included angle. The two inclined columns 212 are connected to the two connecting portions 211a in a one-to-one correspondence. In two adjacent irregular steel columns 210, the four inclined columns 212 are arranged in a W-shape, with the upper ends of the two middle inclined columns 212 connected. The irregular steel column 210 adopts the form of bifurcated column 211 spliced ​​with two inclined columns 212, which facilitates on-site splicing construction, helps control construction accuracy, and improves the strength of the irregular steel column 210.

[0028] According to some embodiments of the present invention, the lower end of the bifurcated column 211 is provided with a column foot 213, thereby the irregular steel column 210 can be stably and reliably fixed to the ground by means of the column foot 213.

[0029] According to some embodiments of the present invention, the bifurcated post 211 includes a first component 2111, a second component 2112, and a third component 2113. The first component 2111, the second component 2112, and the third component 2113 are connected sequentially in a horizontal direction. Two connecting portions 211a are formed by connecting the upper ends of the first component 2111, the second component 2112, and the third component 2113. The lower ends of the first component 2111, the second component 2112, and the third component 2113 are connected to the post base 213. By dividing the bifurcated post 211 into the first component 2111, the second component 2112, and the third component 2113, the second component 2112, located in the middle, can be positioned and connected to the post base 213 first, and then the first component 2111 and the third component 2113 can be connected to both sides of the second component 2112 respectively. Since the second component 2112 is only a part of the bifurcated column 211, it is relatively light during hoisting, making it easier to adjust its position. The positioning accuracy and efficiency of the second component 2112 and the column base 213 are also higher. After connecting the second component 2112 to the column base 213, the first component 2111 and the third component 2113 are then connected to both sides of the second component 2112, completing the assembly of the bifurcated column 211. This effectively reduces the difficulty of positioning and connecting the bifurcated column 211 to the column base 213. Furthermore, because the volume of the object hoisted in a single operation is reduced, the space requirements of the site are also reduced.

[0030] In other embodiments, the bifurcated post 211 may also be configured in other ways. For example, the bifurcated post 211 may include a fourth component 2114, a fifth component 2115, and two sixth components 2116. The fourth component 2114 is connected to the lower end of the fifth component 2115, and the upper end of the fifth component 2115 is connected to the two sixth components 2116. Each connecting part 211a is disposed on the upper end of each sixth component 2116. By dividing the bifurcated post 211 into the fourth component 2114, the fifth component 2115, and the sixth component 2116, the lowermost fourth component 2114 can be positioned and connected to the post base 213 first, then the fifth component 2115 can be connected to the fourth component 2114, and finally the two sixth components 2116 can be connected to the upper end of the fifth component 2115 respectively, thus completing the assembly of the bifurcated post 211. Since the fourth component 2114 is only a part of the bifurcated column 211, it is relatively light in weight during hoisting, and it is easier to adjust the position of the fourth component 2114. This effectively reduces the difficulty of positioning and connecting the bifurcated column 211 and the column base 213. Furthermore, since the volume of the object hoisted in a single operation is reduced, the space requirements of the site are also reduced.

[0031] According to some embodiments of the present invention, at least one outer surface of the forked post 211 is connected to a plate 2117, the plate 2117 extending from the upper end of the forked post 211 to the lower end of the forked post 211, wherein the plate 2117 spans the weld between the constituent components of the forked post 211 and connects the constituent components of the forked post 211 into a whole, and increases the thickness of the forked post 211, thereby improving the overall strength of the forked post 211.

[0032] According to some embodiments of the present invention, each inclined column 212 includes at least two steel beams 2121 connected sequentially along its length, wherein the steel truss 300 is connected to the steel column or branch column 211 at the same height. Since each steel beam 2121 is only a part of the inclined column 212, the weight of a single steel beam 2121 is small and its length is short during hoisting, which facilitates hoisting. The position of the steel beam 2121 can be adjusted segment by segment, which facilitates the control of the installation accuracy of each segment of the steel beam 2121, effectively reducing the assembly difficulty of the inclined column 212. Furthermore, since the volume of the object hoisted at one time is reduced, the space requirements of the site are also reduced.

[0033] During construction, temporary support components for connecting and positioning irregular steel columns 210 can be installed on the core tube steel column 100 to facilitate the assembly of irregular steel columns 210 and ensure the tilt angle of the inclined column 212 of the irregular steel column 210.

[0034] In the specific implementation process, the difficulty in installing the steel truss 300 lies in the connection node between the steel truss 300 and the irregular steel column 210. Because the height of the steel truss 300 is different, in addition to the steel truss 300 connected to the steel beam 2121 of the irregular steel column 210, there may also be a steel truss 300 installed at the bifurcation column 211.

[0035] Since the chords 310 on the steel truss 300 include horizontal chords 310, inclined chords 310, and vertical chords 310, and the steel beams 2121 of the irregular steel columns 210 are usually inclined relative to the chords 310 of the steel truss 300, and the outer surface of the steel beams 2121 is generally provided with shear studs, longitudinal reinforcement, etc., directly welding the chords 310 in different directions to the inclined steel beams 2121 is difficult to construct, and it is not easy to adjust the welding position of the chords 310, making it difficult to control the weld quality. Therefore, according to some embodiments of the present invention, the steel beams 2121 connected to the steel truss 300 are provided with a first butt joint 2122, which is used for butt welding with the corresponding chords 310 of the steel truss 300. Compared to the chord 310 of the steel truss 300, the size and weight of the first connecting part 2122 are smaller. The first connecting part 2122 is easier to weld to the steel beam 2121 and its position is easier to adjust, thus ensuring the welding quality between the first connecting part 2122 and the steel beam 2121. The first connecting part 2122 is positioned opposite the corresponding chord 310, making it easier to weld the first connecting part 2122 to the chord 310 and making it easier to control the welding quality between the first connecting part 2122 and the chord 310. This reduces the welding difficulty between the steel truss 300 and the steel beam 2121 of the irregular steel column 210 and improves the welding quality.

[0036] According to some embodiments of the present invention, a second connecting portion 211 is horizontally provided on the branch column 211 connected to the steel truss 300, and a third connecting portion 2119 is vertically provided on the branch column 211 connected to the steel truss 300. The third connecting portion 2119 is located between two connecting portions 211a. The second connecting portion 2118 is used for butt welding to the corresponding chord member 310 of the steel truss 300, and the third connecting portion 2119 is used for butt welding to the corresponding chord member 310 of the steel truss 300. In specific implementation, since the branch column 211 connects two inclined columns 212, and the inclined columns 212 can be used as inclined chord members 310 of the steel truss 300, the inclined connecting portion can be omitted on the branch column 211. Through the above arrangement, the connection and assembly between the branch column 211 and the steel truss 300 can be facilitated, the welding quality can be guaranteed, and the connection strength can be improved.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
