[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 3 The present application provides an umbrella-shaped support column 3, comprising: a plurality of columns 1, the top ends of the columns 1 being arranged at equal intervals in the circumferential direction; a support plate 2, connected to the top ends of the plurality of columns 1; a plurality of support columns 3, the first ends of which are connected to the support plate 2, and the second ends of the plurality of support columns 3 extend divergently in a direction away from the support plate 2; a truss 4, connected to the plurality of support columns 3 through a web 5.

[0031] In this embodiment, the present application provides an umbrella-shaped support column 3 with strong spanning ability, high force transmission efficiency and smaller space occupation. The top of each column 1 is arranged at equal intervals in the circumferential direction, and the bottom surface of the support plate 2 is connected to the top of each column 1. At the same time, a support column 3 is arranged on the top surface of the support plate 2. The truss 4 is connected to the support column 3 through a plurality of web members 5. The truss 4 is connected to the support column 3 by the web members 5, which can disperse the gravity of the truss 4 to each web member 5. The more web members 5 there are, the more the gravity of the truss 4 is dispersed, and the smaller the pressure on the connection point of each web member 5 and the support column 3. Therefore, a plurality of web members 5 are provided, and a plurality of connection points with the support column 3 are also provided, which can disperse the gravity of the truss 4 to multiple positions on the support column 3, avoiding excessive force at the connection point between the support column 3 and the web member 5, resulting in stress concentration, thereby extending the overall service life of the web member 5 and the support column 3.

[0032] At the same time, the support columns 3 are arranged in a divergent shape on the support plate 2, which can enable the support columns 3 to provide strong structural support. The support columns 3 can withstand greater weight and have more areas to bear the weight of the truss 4. This design of the support columns 3 enables them to more effectively resist natural forces such as wind pressure and earthquakes, thereby enhancing the overall stability of the building.

[0033] The truss 4 is connected to the support columns 3 via a plurality of web members 5, so that a support relationship similar to a mesh structure is formed between the truss 4 and the support columns 3. The web members 5 include straight rods and diagonal rods, which cooperate with the main skeleton of the support columns 3 and the truss 4 to form a plurality of triangular support frames between them. The number of web members 5 is determined according to factors such as the scale and load-bearing requirements of the truss 4. The more web members 5 there are, the more the gravity of the truss 4 can be distributed to more locations, reducing the stress on each connection point. When arranging, their positions and angles should be reasonably planned so that their connection with the support columns 3 and truss 4 conforms to the principles of mechanics and forms a stable support structure. The web members 5 are usually made of high-strength steel, such as round steel or steel pipe. The connection method with the support columns 3 and truss 4 can be welding or bolting. When welding, it is necessary to ensure that the weld quality meets the structural load requirements. For bolting, it is important to select bolts of appropriate specifications and control the tightening torque to ensure that the web members 5 can stably play the role of distributing the load, enhancing the structural strength and stability in the entire structural system.

[0034] The connection between the support column 3 and the support plate 2 can enhance the stability of the entire umbrella-shaped support column 3 structure, distributing the force on the support column 3 to the entire surface of the support plate 2, which then distributes the force to each column 1. Furthermore, the provision of the support plate 2 allows the support column 3 to be connected to the support plate 2 instead of directly to the top of the column 1, increasing the contact area of ​​the support column 3, thereby improving construction efficiency and significantly enhancing construction speed and quality. Furthermore, one of the main purposes of the provision of the support plate 2 is to enhance the stability of the structure. By properly configuring the support plate 2, the load of the truss 4 can be effectively transferred and distributed, thereby reducing local load pressure on the support column 3 and preventing structural damage at the connection point between the web member 5 and the support column 3 caused by external forces. The provision of the support plate 2 can also significantly improve the load-bearing capacity of the support column 3. It can serve as additional structural support for the column 1, sharing the weight and load of the truss 4, thereby enhancing the overall load-bearing capacity of the support column 3 and ensuring that the support column 3 remains safe and stable during long-term use.

[0035] By adopting the above technical solution, the umbrella-shaped support column 3 of the present application can be applied to buildings with large spans, high heights or complex structures, which can significantly improve the overall stability of the building. The present application can also have the advantages of strong spanning ability and high force transmission efficiency, significantly improving the overall stability of the building. Compared with the existing truss 4 structure, it occupies less space and can further reduce the impact of the truss 4 structure on the interior space, functional layout, building lighting and appearance of the building while meeting the support requirements.

[0036] Continue to refer to Figure 2 and Figure 3In one embodiment, four columns 1 are provided, and the columns 1 are arranged symmetrically in the circumferential direction. The centers of the symmetrically arranged columns 1 are connected by a lattice column tensioning method. The bottom ends of the columns 1 are fixedly connected to each other.

[0037] In this embodiment, the top ends of the columns 1 are distributed at equal intervals in the circumferential direction, and there are four columns 1, which can evenly distribute the force on the support plate 2 by the four columns 1, and jointly share the force from the support plate 2, making the overall structure more stable, able to more evenly disperse the load, reduce the stress pressure of a single column 1, and thus improve the durability of the overall structure.

[0038] Reference Figure 2 During actual construction and installation, the columns 1 must be precisely measured and positioned to ensure that the angles and spacing between the columns 1 meet the design requirements. Positioning can be performed with the help of measuring instruments such as total stations to ensure that the columns 1 are evenly distributed so that they can evenly share the force transmitted from the support plate 2. The bottom ends of the columns 1 are fixedly connected to each other, and reliable connection methods such as welding and high-strength bolt connections can be used. For example, when welding, the corresponding welding process standards must be followed to ensure the quality of the weld and a firm connection. When using high-strength bolts for connection, attention must be paid to the selection of bolt specifications and the control of the tightening torque to prevent loosening. In this way, the columns 1 form a stable overall foundation structure to jointly bear the load transmitted from above.

[0039] The tension connection structure at the center of the column 1 can be connected to the lattice column by providing connecting lugs and other connectors at the corresponding nodes of the lattice column, and the connection parts must be well protected against rust and corrosion. This tensioning method can form a coordinated force-bearing overall structure at the center of each column 1, increasing the structural strength, stability, and rigidity. When bearing loads, especially bending loads, the load can be more evenly distributed to each lattice column and tension member, reducing the stress on a single member and better resisting deformation, thereby improving the durability of the overall structure. At the same time, the advantages of the lattice column saving materials and the optimized tension connection structure reducing material usage and lowering costs are brought into play.

[0040] Placing a lattice column at the center of column 1 can enhance its bending resistance. Connecting the lattice columns using a tensioning method further strengthens the column's bending resistance, allowing it to better resist deformation when subjected to bending loads. The tensioning method can help distribute the load more evenly across the lattice columns, reducing stress on individual components and improving the durability of the overall structure. Lattice columns inherently save material, and the tensioning method can further reduce costs by optimizing the connection structure and reducing unnecessary material usage.

[0041] In an operative embodiment, the truss 4 includes a main frame arranged in a cross shape, the bottom of the main frame is connected to the web 5. The main frame includes a support surface 41, along the first direction ( Figure 1 In the X direction), the first connecting rods 42 are extended on both sides of the support surface 41; along the second direction ( Figure 1 Second connecting rods 43 extend from both sides of the support surface 41 (indicated by the Y direction in the middle). The first direction is perpendicular to the second direction. The first connecting rod 42 comprises two circular tubes arranged parallel to the first direction, while the second connecting rod 43 comprises two circular tubes arranged parallel to the second direction.

[0042] In this embodiment, the truss 4 adopts a main frame arranged in a cross shape, and its support surface 41 serves as the main force and load-bearing area. Figure 1 In the X direction, a first connecting rod 42 is provided on both sides of the support surface 41 and is composed of two circular tubes arranged parallel to the first direction; along the second direction ( Figure 1 (As shown in the Y direction in the middle), a second connecting rod 43 is provided, which is composed of two circular tubes arranged parallel to the second direction, and the first direction is perpendicular to the second direction. The length of the circular tubes can be adjusted as needed. The adjustable length and stable structure of the circular tubes make it suitable for supporting buildings of different heights and widths, effectively supporting and fixing various parts of the building. Its length can be adjusted on the construction site by cutting, welding, etc. to adapt to different working conditions. This adjustability, combined with its stable cross-shaped structure, allows the truss 4 to be flexibly applied to buildings of different sizes and different space requirements. In addition, the relatively low cost of steel pipe materials and the simple manufacturing and installation process help further reduce the cost of the entire building structure. At the same time, the strength and toughness of the circular tubes enable them to withstand certain impacts and vibrations during use, ensuring the safety of the structure. The use of steel pipes reduces the overall material cost, simplifies the structure, and makes the manufacturing and installation process relatively simple, further reducing costs. At the same time, the material of the circular tubes can be selected from steel pipes that meet the standards for building structural steel. The pipe diameter and wall thickness are determined according to factors such as the load size and span that the truss 4 needs to bear. During the production process, the round tubes are connected into an integral cross-shaped main skeleton structure through welding and other processes according to the design requirements to ensure the welding quality, so that the main skeleton has good stability and load-bearing capacity and can withstand large loads.

[0043] In an implementable embodiment, the support plate 2 is a square plate, and four support columns 3 are arranged in sequence along the corners of the support plate 2. First reinforcing ribs 6 are arranged between the support columns 3, and the support surface 41 and the first reinforcing ribs 6 are connected by a web 5.

[0044] In this embodiment, the support plate 2 is designed as a square plate, typically made of a metal sheet with a certain strength and rigidity, such as steel. Support columns 3 are arranged along the corners of the support plate 2 to increase the spacing between the support columns 3. The thickness of the support plate 2 should be determined based on the load transmitted by the support columns 3, trusses 4, and other structures it carries, to ensure sufficient load-bearing capacity. Quality requirements such as the flatness of the support plate 2 should also be considered to ensure a good fit at the connection points with the columns 1, support columns 3, and other components.

[0045] The bottom surface of the support plate 2 is fixed to the top of each column 1 through welding or high-strength bolts. When welding, the weld seam must be continuous and full, and when bolting, the preload force of the bolts must be strictly controlled. When connecting the top surface to the support column 3, a reliable connection method is also used to ensure smooth force transmission between the support column 3 and the support plate 2. This allows the force on the support column 3 to be effectively distributed across the entire surface of the support plate 2, and the support plate 2 then evenly distributes the force to each column 1.

[0046] The first reinforcing rib 6 and the end of the web 5 intersect on the support column 3 or the support surface 41, and are firmly connected to the relevant structure by welding or other means to form a triangular frame. The triangular frame structure has the advantage of structural stability. By arranging the first reinforcing rib 6 between the support column 3 and the support surface 41, the structural strength of the connection between the support column 3 and the truss 4 can be further improved, making the force transmission between them smoother, and jointly enhancing the stability of the entire umbrella-shaped support column 3 structure, and better bearing and distributing the load.

[0047] In an implementable embodiment, the truss 4 and the support column 3 are connected in a lower chord node manner of a stiff web member 5 .

[0048] In this embodiment, the support column 3 is used to bear the overall gravity of the truss 4. A special node design is performed on the support column 3. The node position should take into account factors such as the connection angle of the web member 5 and the direction of force. A node plate can be welded to the support column 3, and corresponding bolt holes or slots are provided on the node plate to connect with the web member 5. The connection between the web member 5 and the node plate can be made by high-strength bolt connection or welding to ensure a firm and reliable connection. The use of a lower chord node method of a rigid web member 5 can give the support column 3 an excellent load-bearing capacity. During the load-bearing process, the node can maintain stable mechanical properties, ensuring that the force is effectively transmitted between the truss 4 and the support column 3. It can ensure that the connection point between the support column 3 and the web member 5 maintains stable mechanical properties during the load-bearing process. In addition, the rigid skeleton structure composed of the web member 5 itself has high rigidity, which can effectively resist the deformation of the truss 4 when subjected to various loads, maintain the stability of the entire structure, and effectively resist deformation.

[0049] In an implementable embodiment, the support columns 3 are arranged in an arc shape, and a second reinforcing rib 7 is provided between two adjacent support columns 3 .

[0050] In this embodiment, the curved support column 3 enhances its aesthetic appearance. Furthermore, the curved shape of the support column 3 alters stress distribution, reducing stress concentration points on the support column 3 and ensuring that the support column 3 is less susceptible to bending. The curved support column 3 can be manufactured by cold or hot bending processes using metal pipes (e.g., steel pipes). The curvature of the arc must meet design requirements to ensure consistent structural performance.

[0051] A second reinforcing rib 7 is provided between two adjacent support columns 3, with one end of the two adjacent second reinforcing ribs 7 intersecting on the support column 3. During installation, the two adjacent second reinforcing ribs 7 are aligned to form a stable triangular frame structure, which is then securely connected to the support column 3 through welding or other methods. Multiple triangular frame structures can further enhance the structural strength of the support columns 3, enabling them to better withstand the load transmitted by the trusses 4 and resist external natural forces. This further enhances the structural strength of the support columns 3.

[0052] In addition, the first reinforcing rib 6 and the second reinforcing rib 7 can intersect at the same point on the support column 3. In the entire umbrella-shaped support column 3 structure, multiple reinforcing ribs cooperate with each other to form a more complex and stable spatial force system, improving the strength and stability of the structure from different directions and levels. This allows the entire umbrella-shaped support column 3 to maintain good mechanical properties when facing complex external forces (such as wind pressure, earthquakes, loads in different directions, etc.), providing reliable support for the umbrella-shaped steel truss roof above and the entire building, ensuring the safety and stability of the entire building.

[0053] The present application also provides an umbrella-shaped column building, the roof of the building is an umbrella-shaped steel truss, and the bottom of the roof uses the umbrella-shaped support column 3 in the present application as the bottom column.

[0054] In this embodiment, the roof utilizes umbrella-shaped trusses, which simplify the structure and allow for flexible adjustment of component lengths, angles, and cross-sectional shapes to accommodate diverse needs. This arrangement ensures excellent stability under external forces while also enhancing the aesthetic appeal of the structure. It effectively resists various external forces and deformation, ensuring structural safety and stability. Furthermore, the umbrella-shaped trusses offer a unique appearance and visual appeal, enhancing the overall aesthetics of the building.

[0055] Umbrella-shaped trusses can be flexibly adjusted in length, angle, and cross-sectional shape to meet the needs of different building functions, spaces, and appearances. For example, in buildings with different span requirements, the length of the main frame tubes and the number of web members can be appropriately increased or decreased to meet the corresponding load and space requirements. Component angles can also be adjusted to suit the architectural design, creating unique roof shapes.

[0056] The umbrella-shaped column building adopts the umbrella-shaped support column 3 in this application as the base column, which can greatly improve the stability of the building, and can have the advantages of strong spanning ability and high force transmission efficiency. The umbrella-shaped rigid truss multiple triangular support frames and the reasonable component connection method can effectively disperse and transmit external forces, avoid local excessive force and structural damage, and significantly improve the overall stability of the building. Compared with the existing truss structure, it occupies less space and can further reduce the impact of the truss structure on the interior space, functional layout, building lighting and appearance of the building while meeting the support requirements.
