Description

Technical Field

[0001] This application relates to a steel column structure with a nine-sided triangular facet and a T-shaped cross section, and its manufacturing method, belonging to the technical field of supporting components in buildings. Background Technology

[0002] The application of steel structure buildings in the construction industry is becoming increasingly widespread, especially in large-span buildings such as stadiums, airports, platforms, and bridges. Steel structures have the advantages of superior safety performance, beautiful appearance, and strong plasticity.

[0003] With the widespread application of steel structures, the requirements for building design are becoming increasingly stringent. While considering aesthetics and structural load-bearing requirements, the effective transfer of forces at joints and the stability of the joint structures are crucial factors that need to be considered. Especially in irregularly shaped buildings, the uneven stress distribution or unstable support at connection joints during the construction of steel components with other components, walls, bridges, etc., can lead to poor stress distribution. This can cause additional torque and bending moments during the building's use, compromising its safety. Summary of the Invention

[0004] In view of this, this application firstly provides a steel column structure with a nine-sided triangular face turning into a T-section, which not only achieves internal structural stability of the supporting member, but also endows the supporting member with good load-bearing performance.

[0005] Specifically, this application is implemented through the following scheme:

[0006] A nine-sided triangular face to T-section steel column structure includes a T-section steel column, a nine-sided triangular mechanism and a sealing plate. The top surface of the nine-sided triangular mechanism is a horizontal top surface, and its bottom is fixedly connected to the T-section steel column. The sealing plate is located inside the nine-sided triangular mechanism.

[0007] The above structure not only enables the conversion and installation between T-section steel columns and triangular faces, but the irregular shape of the structure also increases the usable space. When used in wall supports, bridge columns, and other applications, it expands the load-bearing capacity from the four sides of a conventional cubic column to nine sides. Combined with the triangular triangular stable structure of the sectional structure at the same level, the overall stability is higher, giving a small cross-section a large load-bearing effect.

[0008] Furthermore, as a preferred option:

[0009] The T-shaped steel column is a steel column formed by the closed splicing of three U-shaped boxes. More preferably, the included angle θ between adjacent U-shaped boxes is 120 ˚.

[0010] The nine-sided triangular mechanism includes three triangular facets, each with a different orientation but the slices are at the same level, making the top of the nine-sided triangular mechanism a horizontal top surface.

[0011] Preferred:

[0012] The triangular unit is composed of three bent plates spliced ​​together, with the upper part of the bent plates forming a triangle and the lower part fixedly connected to a T-shaped steel column. More preferably, the upper and lower parts of the bent plates are connected by a sealing plate to achieve internal fixation of the nine-sided triangular mechanism.

[0013] At least one triangular facet unit is provided with a longitudinal stiffening rib. More preferably, the longitudinal stiffening rib is connected to two sides of the triangular facet unit and is parallel to the remaining side.

[0014] The T-section steel column is provided with an internal diaphragm, and at least one internal diaphragm is provided. More preferably, two internal diaphragms are provided, one located at the bottom of the T-section steel column and the other in the middle section of the T-section steel column. The shape of the internal diaphragm is consistent with the inner cross-section of the T-section steel column, which facilitates its abutment against the inner wall of the T-section steel column to maximize the uniform stress distribution of the entire structure. The two internal diaphragms are preferably arranged horizontally.

[0015] In the above structure, the T-shaped steel column at the bottom is easy to construct and install; the triangular face at the top is a nine-sided triangle stable structure. The overall structure is axially symmetrical. In load-bearing applications such as bridges and steel structures, it solves the design and fabrication problems of stress and T-shaped steel column, bending and twisting joints, and nine-sided triangle mechanism connection points. It has the advantages of high structural stability, small cross-section but large load-bearing capacity, reasonable spatial distribution, and beautiful appearance.

[0016] The applicant's second objective is to provide a method for fabricating the aforementioned nine-sided triangular facet to T-section steel column structure, the steps of which are as follows:

[0017] Step 1: Assemble and weld three U-shaped boxes;

[0018] Step 2: First, assemble and weld two of the U-shaped boxes, ensuring that the included angle between the two U-shaped boxes is 120°. Then, weld the third U-shaped box to the two assembled and welded U-shaped boxes to obtain a T-section steel column.

[0019] Step 3: Weld six bent plates to the top of the T-section steel column to form three sets of V-shaped structures with inward openings;

[0020] Step 4: Assemble and weld three bent plates at the openings of the three V-shaped structures to form three triangular structures at the top of the T-section steel column;

[0021] Step 5: Assemble and weld the sealing plate in the middle of the three triangular structures to obtain the finished nine-sided triangular mechanism to T-section steel column structure. Attached Figure Description

[0033] This application provides a steel column structure with a nine-sided triangular facet turning into a T-section, combined with... Figure 1 , Figure 2 , Figure 3 It includes a T-section steel column 1, a nine-sided triangular mechanism 2, and a sealing plate 3. The cross-section (top surface) of the nine-sided triangular mechanism 2 is a horizontal top surface containing nine edges 2d and three triangular structures 2e. Its bottom is fixedly connected to the T-section steel column 1. The sealing plate 3 is located inside the nine-sided triangular mechanism 2 and transmits longitudinal force when subjected to force, so as to realize the internal stability of the nine-sided triangular mechanism 2.

[0034] in:

[0035] The T-section steel column 1 is composed of three U-shaped boxes 11 spliced ​​together, forming a closed, irregular T-shaped structure. Each U-shaped box includes a first sidewall 12 and a second sidewall 13. Figure 4 The included angle θ between adjacent U-shaped boxes 11 is 120 ˚. During the installation of adjacent U-shaped boxes 11, brazing filler metal 15 can be filled into the gap formed between the adjacent plates of adjacent U-shaped boxes 11, which is larger on the outside and smaller on the inside. Then, steel blocks 16 are fixed inside the gaps, and then the area is welded to ensure that the connection nodes of adjacent U-shaped boxes 11 are subjected to uniform stress.

[0036] The nine-sided triangular mechanism 2 includes three components: triangular facet unit 1 2a, triangular facet unit 2b, and triangular facet unit 2c, which are combined with... Figure 2 Triangular face unit 2a, triangular face unit 2b, and triangular face unit 2c have different orientations but the slices are at the same level, making the top of the nine-sided triangular mechanism 2 a horizontal top surface.

[0037] Specifically, in combination Figure 5Each of the three triangular facets is composed of three bent plates: bent plate 1 (21), bent plate 22 (22), and bent plate 3 (23). Bent plate 1 (21) and bent plate 22 (22) are each divided into an upper part (24) and a lower part (25). The upper part (24) and the lower part (25) are integral bent structures. The inner side of the junction between the upper part (24) and the lower part (25) is connected by a sealing plate (3) to achieve internal fixation of the nine-sided triangular mechanism 2. The upper parts (211) of the three bent plates are assembled to form a triangular structure 2e. The outer side of the lower part of bent plate 1 (21) is connected to the second side wall (13). The lower part of bent plate 3 (23) is located inside the first side wall (12). The lower part of bent plate 2 (22) is located inside the T-section steel column (1), and its two sides are connected to the inner wall of the T-section steel column (1).

[0038] Preferred: Combination Figure 5 Taking one of the triangular face units as an example, the top of the U-shaped box 11 protrudes upward, forming a slot 14 between it and the first side wall 12 and the second side wall 13 on both sides, which facilitates the fixing of the bending plate 11, the bending plate 23 and the U-shaped box 11.

[0039] As an alternative: combining Figure 5 Furthermore, a triangular end sealing plate 26 of corresponding specifications can be installed on the top surface of the aforementioned triangular structure. The triangular end sealing plate 26 is fitted inside the triangular structure 2e to seal the top of the triangular unit. Three triangular end sealing plates 26 can be provided, that is, one triangular end sealing plate 26 corresponds to each triangular unit.

[0040] As an alternative: each triangular unit is equipped with longitudinal stiffening ribs 4, combined with... Figure 6 The longitudinal stiffening rib 4 connects to two sides of the triangular facet unit and is parallel to the remaining side. The longitudinal stiffening rib 4 provides support for the triangular structure within the triangular facet unit, assisting the three bent plates in stabilizing the structure. Figure 6 For example: the longitudinal stiffening rib 4 is connected to the bending plate 1 21 and the bending plate 3 23, and is parallel to the bending plate 2 22.

[0041] As an alternative: combining Figure 6 The T-section steel column 1 is equipped with an inner diaphragm 5, and at least one inner diaphragm 5 is provided. For example, two inner diaphragms can be provided in each nine-sided triangular mechanism to T-section steel column structure, one inner diaphragm located at the bottom of the T-section steel column 1 and the other inner diaphragm located in the middle section of the T-section steel column 1. The shape of the inner diaphragm 5 is consistent with the inner cross-section of the T-section steel column 1, so as to facilitate its abutment against the inner wall of the T-section steel column 1, so as to maximize the uniform stress of the entire structure. Both inner diaphragms 5 are preferably arranged in the horizontal direction.

[0042] The fabrication method for the above-described nine-sided triangular mechanism to T-section steel column structure is as follows:

[0043] Step 1, construct the U-shaped box 11: assemble and weld three U-shaped boxes 11 separately. During the assembly process, add cross supports inside the U-shaped box 11 to prevent deformation of the U-shaped box 11.

[0044] Step 2, fix the inner partition 5: assemble and weld two of the assembled U-shaped boxes at an inclination angle of 30° relative to the horizontal plane (i.e., the included angle θ is 120°), and weld the two sides of the inner partition 5 to the inner groove opened on the inner side of the two U-shaped boxes 11.

[0045] Step 3, construct T-section steel column 1: cover the two assembled and welded U-shaped boxes from above with the third U-shaped box, and weld the third U-shaped box to the two assembled U-shaped boxes; at the same time, weld the two inner partition plates 5 to the third U-shaped box through the channels at the upper and lower ends of the U-shaped box 11, and obtain the T-section steel column 1.

[0046] Step 4, constructing triangular structure 2e: First, assemble and weld a total of six bent plates 21 and 23 on the outer edge of the U-shaped box 11 to the top of the T-section steel column 1; then assemble three longitudinal stiffening ribs 4 at the included angle of bent plates 21 and 23, and weld them to the six bent plates 21 and 23 at the included angle; finally, assemble three bent plates 22 on the inner side of the six bent plates 21 and 23 to form triangular structure 2e, and weld the outer weld of triangular structure 2e; weld the weld between bent plates 22 at the middle of triangular structure 2e to complete the construction of the three triangular structures 2e.

[0047] Step 5: Install sealing plate 3: Assemble sealing plate 3 between the three triangular structures 2e, and weld the gap between sealing plate 3 and the adjacent bent plate 22;

[0048] Step 6, Install the triangular end cap 26: Assemble one triangular end cap 26 in each triangular structure 2e, and weld the gap between the triangular end cap 26 and the inner wall of the triangular structure 2e.

[0049] The above steps complete the construction of the lower T-section steel column 1 and the upper nine-sided triangular mechanism 2.

[0050] In the above structure, the T-shaped steel column 1 at the bottom is composed of three U-shaped boxes 11 spliced ​​together, which is convenient to construct and easy to install; the nine-sided triangular mechanism 2 at the top is a nine-sided triangular stable structure. During installation, the top of this structure forms a nine-sided contact with the corresponding wall or bridge with nine edges 2d, and all nine edges are on the same horizontal plane, which effectively disperses the force and achieves a large load-bearing capacity for a small cross section; the overall structure is an axisymmetric irregular structure, which is convenient for supporting narrow and irregular spaces, has high structural stability, reasonable spatial distribution, and beautiful appearance.

However, they should not be construed as limiting the scope of the present invention, nor are the embodiments intended to limit the scope of protection in the claims of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the concept of the present invention. All equivalent implementations or changes that do not depart from the present invention should be included in the technology of the present invention.
