Description

Technical Field

[0001] This utility model relates to the field of steel structure factory building technology, specifically to a multi-level load-bearing column for factory steel structure. Background Technology

[0002] A corbel column generally refers to a corbel, which serves as a support structure under beams in a mixed structure. Its function is to distribute the force of the beam support to the load-bearing structure below, because too much concentrated force on one side can easily damage the wall.

[0003] Chinese utility model patent application number 201920889179.9 discloses a corbel column for factory buildings, including a rib plate and a column body. A rib plate is provided on the surface of the left end of the column body, and the rib plate is welded to the column body. A corbel seat is provided on the surface of the right end of the column body, and the column body and the corbel seat are welded together. A second support seat is provided at the connection between the corbel seat and the upper end of the column body, and a first support seat is provided at the connection between the corbel seat and the lower end of the column body. The first support seat is fixedly connected to the column body by bolts. Although this corbel column solves the problem of gaps appearing at the connection between the corbel column and the column body under long-term upper loads, leading to collapse, its single-layer corbel structure causes load transfer to concentrate in a local area. It cannot adapt to the needs of multi-story equipment layouts, making it difficult to achieve three-dimensional load layering, resulting in limited factory space planning and low space utilization.

[0016] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-2 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0017] See Figure 1-2 A multi-level load-bearing steel structure for factory buildings includes an I-beam 1, a parapet column 2 welded to the top right side of the I-beam 1, a first corbel 3 fixed to the lower middle part of the front side of the I-beam 1, and a second corbel 4 fixed to the upper middle part of the rear side of the I-beam 1.

The front side of the first support plate 33 is provided with a first mounting block 34 protruding forward. The first mounting block 34 is provided with a plurality of first mounting holes 35 laterally. The second bracket seat 4 includes a second top plate 41 and a second bottom plate 42 that are welded laterally parallel to each other in the upper middle part of the rear side of the web plate 11, and a second support plate 43 that is welded vertically between the second top plate 41 and the second bottom plate 42. The rear side of the second support plate 43 is welded to the rear side of the web plate 11. The front side of the second support plate 43 is provided with a second mounting block 44 protruding forward. The second mounting block 44 is provided with a plurality of second mounting holes 45 laterally.

[0018] The multi-level support column of the steel structure of the factory building of this utility model forms a multi-level layered support system by setting parapet wall columns 2, first bracket seats 3 and second bracket seats 4 at the top, upper middle and lower middle parts of the I-beam 1, respectively. It can bear multiple loads at the same time and realize the three-dimensional utilization of the factory space. The bracket seat adopts a welded structure of top plate, bottom plate and support plate, combined with the design of forward protruding mounting blocks and mounting holes, which enhances the local bending stiffness and simplifies the equipment installation process.

[0019] In this embodiment, a fixing plate 5 inclined upward from right to left is welded to the top of the I-beam 1. A first support plate 51 and a second support plate 52 are vertically welded to the bottom of the fixing plate 5, corresponding to the front and rear sides of the web 11. A first reinforcing rib 53 and a second reinforcing rib 54 are welded to the left side of the first side plate 12, corresponding to the positions of the first support plate 51 and the second support plate 52. A first rib plate 55 and a second rib plate 56 are welded to the bottom of the first support plate 51 and the second support plate 52, respectively. At least one third mounting hole 57 is laterally opened on the top of the first support plate 51, and at least one fourth mounting hole 58 is laterally opened on the top of the second support plate 52. This structure distributes the top load along the axis of the I-beam 1 to the web 11 and the side flanges, avoiding localized stress concentration. The vertically welded first support plate 51 and second support plate 52 provide vertical compressive and shear support. The third mounting hole 57 on the top of the first support plate 51 and the fourth mounting hole 58 on the top of the second support plate 52 can serve as standardized connection interfaces for equipment or secondary beams, enabling rapid installation. Local reinforcement through the first rib 55, second rib 56, first reinforcing rib 53, and second reinforcing rib 54 disperses the stress peak at the welded joint, reducing the risk of fatigue cracking under long-term dynamic loads.

[0020] In this embodiment, the top of the first side plate 12 protrudes beyond the top of the fixing plate 5, and a first reinforcing block 59 is welded to the top of the fixing plate 5. The left side of the first reinforcing block 59 is welded to the right side of the top of the first side plate 12. The provision of the first reinforcing block 59 can increase the stability of the top structure of the load-bearing column.

[0021] In this embodiment, a vertically inclined fixing block 6 is welded to the top of the fixing plate 5. The fixing block 6 has multiple first fixing holes 61 horizontally. A second reinforcing block 62 is welded to the right side of the fixing block 6, and the bottom of the second reinforcing block 62 is welded to the top of the fixing plate 5. The fixing block 6 and the first fixing holes 61 serve as standardized connection points for the steel structure components of the factory building, enabling rapid installation. The second reinforcing block 62 enhances the stability of the structure.

[0022] In this embodiment, the top of the first side plate 12 is provided with multiple second fixing holes 14 at both the upper and lower ends of the fixing plate 5, the first reinforcing rib 53, the second reinforcing rib 54, the first rib plate 55, and the second rib plate 56. By providing multiple second fixing holes 14 at the top of the first side plate 12, the load-bearing column and the steel structure accessories of the factory building can be quickly assembled and disassembled without any fixing structure for auxiliary positioning, which greatly shortens the installation time.

[0023] In this embodiment, third ribs 36 are welded to the rear side of the web 11 at positions corresponding to the first top plate 31 and the first bottom plate 32, and fourth ribs 46 are welded to the front side of the web 11 at positions corresponding to the second top plate 41 and the second bottom plate 42. The addition of multiple third ribs 36 and fourth ribs 46 can enhance the torsional resistance and load-bearing capacity of the upper and lower parts of the I-beam 1.

[0024] In this embodiment, a base plate 7 is welded to the bottom of the I-beam 1. Multiple third reinforcing blocks 71 are welded to the top of the base plate 7 corresponding to the outer perimeter of the I-beam 1. The bottom of each third reinforcing block 71 is welded to the top of the base plate 7. Multiple rectangular arrayed second fixing holes 72 are vertically arranged on the top of the base plate 7. The third reinforcing blocks 71 enhance the strength of the connection between the I-beam 1 and the base plate 7, reducing the risk of tilting deformation.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
