Description

Technical Field

[0001] This utility model relates to the field of steel silo technology, and in particular to a circumferential stiffening structure for a rectangular steel silo. Background Technology

[0002] Rectangular steel silos are widely used, especially in the overall layout of silo complexes, due to their advantages in floor space and space utilization. However, unlike circular silos, which can effectively resist the pressure of internal materials by circumferential tension, the straight walls of rectangular steel silos mainly work in the form of bending when subjected to the lateral pressure generated by internal materials.

[0003] This stress distribution pattern leads to two inherent technical challenges. First, the flat silo wall panels are prone to bending and deformation outward under large-area lateral pressure, resulting in significant stress concentration at the corners of the silo. This places extremely high demands on the structural strength and connection reliability at the corners of the silo. Second, the large-area silo wall panels between the two main load-bearing structures are relatively thin, resulting in poor local stability and making them prone to buckling and instability under material pressure.

[0004] To address these issues, existing technologies typically employ complex stiffening systems, such as welding dense horizontal and vertical stiffening ribs onto the silo wall panels to improve overall and local stability. However, this approach often results in a large number of structural components and a massive amount of welding work, which not only increases material costs and construction difficulty but also prolongs the construction period.

[0005] Therefore, this utility model proposes a circumferential stiffening structure for a rectangular steel silo to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the existing technology, the circumferential stiffening structure of a rectangular steel silo has a relatively complex structure and many components, resulting in high cost. In addition, there are problems such as stress concentration at the corners of the silo body and large-area silo wall panels being prone to bulging deformation. The present invention aims to provide a circumferential stiffening structure for a rectangular steel silo with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a circumferential stiffening structure for a rectangular steel silo, including multiple silo wall panels and multiple vertical columns vertically arranged at the corners of the silo wall panels; as well as multiple horizontal steel beams of square steel pipes and multiple vertical stiffening ribs arranged at horizontal intervals along the height direction of the silo body.

[0008] The plurality of square steel tube horizontal steel beams are horizontally encircled around the silo body and fixedly connected to the plurality of vertical columns. Furthermore, the plurality of vertical stiffening ribs are arranged between two adjacent vertical columns and are combined by connecting one end of the vertical stiffening rib to the silo wall panel and the other end to the vertical column.

[0009] Preferably, the connection between the silo wall panel and the vertical column, the connection between the square steel pipe horizontal beam and the vertical column, and the connection between the vertical stiffening rib and the silo wall panel and the vertical column are all welding.

[0010] Preferably, the horizontal steel beam of the square steel tube is a rectangular tube with a hollow cross section.

[0011] Preferably, the vertical stiffening ribs are vertically arranged on the inner side of the bin wall panel.

[0012] Preferably, the upper and lower ends of the vertical stiffening rib abut against and connect to two adjacent horizontal steel beams made of square steel pipes.

[0013] Preferably, the cross-sectional shape of the vertical stiffening rib is an L-shaped or T-shaped angle steel.

[0014] Preferably, no other horizontally extending stiffening ribs are provided on the silo wall plate between two adjacent horizontal steel beams of the square steel pipe.

[0015] Preferably, the vertical column serves as the main load-bearing component, with its lower end supported by the warehouse support structure.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of weak structure and stress concentration leading to deformation at the corners of rectangular steel silos in the prior art by setting up horizontal steel beams of square steel pipes and welding them to vertical columns to form a closed rectangular rigid frame. It achieves the technical effect of effectively constraining the corners of the silo, resisting deformation, and significantly improving the overall structural stability and load-bearing capacity of the silo.

[0017] 2. This utility model solves the problem of local buckling deformation and poor stability of large-area warehouse walls due to uneven stress in the prior art by adding vertical stiffening ribs between adjacent vertical columns and welding the stiffening ribs to the warehouse wall panel and the vertical columns as a whole. It achieves the technical effect of enhancing the local stiffness of the warehouse wall panel, effectively preventing its buckling deformation, and making the load transfer path clearer and more efficient.

[0018] 3. This utility model adopts an integrated reinforcement scheme that combines the horizontal steel beams of square steel tubes with the vertical stiffening ribs, eliminating the need for secondary horizontal stiffening ribs. This solves the problems of numerous stiffening structural components, complex construction, inconvenient construction, and high project costs in the existing technology, achieving the technical effect of reducing the number of components, simplifying construction technology, shortening the construction period, and thus effectively saving project investment.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 2 This utility model provides a circumferential stiffening structure for a rectangular steel silo, which aims to solve the problems of stress concentration at the corners of rectangular silos and the easy bulging deformation of large-area silo wall panels in the prior art.

[0023] like Figure 1 and Figure 2 As shown, the circumferential stiffening structure of the rectangular steel silo includes multiple silo wall panels 4 and multiple vertical columns 3 vertically arranged at the corners formed by the silo wall panels 4. The silo wall panels 4 are used to enclose the storage space that constitutes the silo body, and the vertical columns 3 are used as the main load-bearing frame of the silo body. The silo wall panels 4 and the vertical columns 3 are fixedly connected by welding.

[0024] To effectively enhance the integrity and stability of the silo structure, the circumferential stiffening structure also includes multiple horizontal steel beams 2 made of square steel tubes and multiple vertical stiffening ribs 1; Please refer to Figure 1 and Figure 2Multiple square steel pipe horizontal steel beams 2 are horizontally spaced along the height of the silo and horizontally encircle the entire silo. Their two ends are fixedly connected to the adjacent vertical columns 3 by welding, thus forming a closed rectangular rigid frame. Multiple vertical stiffening ribs 1 are vertically set on the inner side of the silo wall panel 4 between two adjacent vertical columns 3. One side of the vertical stiffening rib 1 is welded and fixed to the inner wall surface of the silo wall panel 4, and the other side is welded and fixed to the vertical column 3. This combination structure of external frame and internal stiffening ribs working together ensures the high stability and anti-bulging deformation ability of the silo when subjected to internal material pressure.

[0025] As a preferred embodiment, in order to ensure the overall rigidity and connection strength of the structure, the silo wall panel 4 and the vertical column 3, the square steel tube horizontal steel beam 2 and the vertical column 3, and the vertical stiffening rib 1 and the silo wall panel 4 and the vertical column 3 are all fixedly connected by welding. The square steel tube horizontal steel beam 2 is preferably a rectangular tube with a hollow cross section to provide higher bending and torsional resistance. In order to further enhance the local stability of the silo wall panel 4, the upper and lower ends of the vertical stiffening rib 1 abut against and are welded to the two adjacent square steel tube horizontal steel beams 2. Its cross-sectional shape can be L-shaped or T-shaped angle steel. In this structural system, no other secondary stiffening ribs extending in the horizontal direction are set on the warehouse wall plate 4 between two adjacent square steel pipe horizontal steel beams 2, which simplifies the structure and reduces the number of components. As the main vertical load-bearing component, the lower end of the vertical column 3 is directly supported and fixed to the support structure or ring beam foundation under the warehouse.

[0026] Working principle: First, the vertical column 3 is supported on the lower support of the silo and the ring beam at the bottom of the silo. The silo wall panel 4 is welded to the vertical column 3. At the same time, the square steel tube horizontal beam 2 uses square steel tubes as horizontal steel beams, which makes the structure more stable and can effectively constrain the stress concentration positions at the corners of the silo. In addition, the device is equipped with vertical stiffening ribs 1, which makes the stress on the silo wall panel 4 more clear. The vertical stiffening ribs 1 are welded to the vertical column 3 and the silo wall panel 4. At the same time, the structure consists only of the square steel tube horizontal beam 2 and the ring stiffening structure, without horizontal stiffening ribs, which reduces the size and number of structural components, thereby saving engineering investment and improving project progress efficiency.
