Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically a special C-shaped steel structure. Background Technology

[0002] C-shaped steel, due to its rational cross-sectional shape, light weight, and high strength, is widely used in the fabrication of frames for buildings, bridges, and various equipment. Typically, C-shaped steel components are connected by welding or bolting to form an integral frame structure, which reduces material usage while ensuring load-bearing capacity, making it a common application in practical engineering. Most existing C-shaped steel components are constructed using single-layer or double-layer combinations, relying on welds, stiffening ribs, or bolts for connection to achieve reinforcement and stability.

[0003] However, because C-shaped steel has an open cross-section, it is prone to warping of the open portion and uneven local stress under external loads or prolonged use. Especially under large spans or high loads, the overall stability of existing C-shaped steel components is insufficient, often requiring additional reinforcements or repeated welding to improve stiffness. This not only increases processing steps but also extends the construction period. Furthermore, the problem of concentrated local stress has not been effectively addressed, leading to easy deformation of the components and affecting their overall service life.

[0004] Therefore, a special C-shaped steel component is needed to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this utility model is to provide a special C-shaped steel component to solve the problems of warping of the opening, uneven local stress, and insufficient overall stability mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special C-shaped steel component, comprising a C-shaped frame and welding blocks, wherein the C-shaped frame consists of two sets of parallel C-shaped steel, and multiple sets of welding blocks are arranged vertically at equal intervals on the rear side of the inner wall of the C-shaped frame, with crossbars welded between each set of welding blocks, and multiple sets of support plates fixed between the crossbars, with connecting bolts fixedly connecting the support plates and the crossbars, and wing plates extending laterally from the top and bottom of the C-shaped frame, with vertical columns welded to the wing plates of the C-shaped frame, the columns being welded to the welding blocks from the outside.

[0007] As a further technical solution of this utility model, the support columns are arranged in three groups parallel to each other on the outside of the C-shaped frame, with each group of support columns distributed at equal intervals.

[0008] As a further technical solution of this utility model, the support plate is welded from rectangular frame intersecting steel bars.

[0009] As a further technical solution of this utility model, a base plate is fixedly connected to the bottom end of the wing plate, a slot is processed on the edge of the contact surface between the wing plate and the base plate, and an inner support is embedded in the wing plate.

[0010] As a further technical solution of this utility model, an outer support is welded to the right side of the inner support, and the edge of the outer support is aligned with the base plate.

[0011] As a further technical solution of this utility model, an outer bolt is fixedly connected between the outer support and the base plate, and an inner bolt is fixedly connected between the inner support and the wing plate.

[0012] As a further technical solution of this utility model, the inner support and the outer support are arranged in opposite directions to form a relative force, and the edge of the wing plate is in contact with the inner wall of the inner support.

[0013] As a further technical solution of this utility model, the bottom of the inner wall of the C-shaped frame is welded to the surface of the base plate, and the inner support feet are correspondingly arranged.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting up C-shaped frame, welding block, crossbar, support plate, connecting bolt, wing plate and column, the whole steel component forms a stable force system with longitudinal and transverse bidirectional constraints. The overall structure can still maintain stability under large span or high load conditions, improve the bearing capacity and ensure the overall stability of the structure. By incorporating wing plates, base plates, slots, inner supports, outer supports, outer bolts, and inner bolts, and employing a C-shaped combination and tie structure at the critical bottom connection, the connection method becomes simpler and can be completed without excessive additional processing, reducing processing and installation steps and shortening the construction period. By incorporating a C-frame, base plate, and internal supports, local loads can be evenly distributed through point support, preventing deformation or warping caused by concentrated forces.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 An embodiment of this utility model provides: a special C-shaped steel component, including a C-shaped frame 4 and welding blocks 3. The C-shaped frame 4 consists of two sets of parallel C-shaped steel. Multiple sets of welding blocks 3 are arranged vertically at equal intervals on the rear side of the inner wall of the C-shaped frame 4. A crossbar 5 is welded between each set of welding blocks 3. Multiple sets of support plates 7 are fixed between the crossbars 5. Connecting bolts 6 are fixedly connected between the support plates 7 and the crossbars 5. Wing plates 1 extend laterally from the top and bottom of the C-shaped frame 4. Columns 2 are vertically welded to the wing plates 1 of the C-shaped frame 4. The columns 2 are welded to the welding blocks 3 from the outside. Three sets of columns 2 are arranged parallel to each other on the outside of the C-shaped frame 4. Each set of columns 2 is distributed at equal intervals. The support plates 7 are welded from rectangular frame cross-structure steel bars. Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the special C-shaped steel component consists of two sets of parallel C-shaped frames 4 as the main load-bearing components. Multiple sets of weld blocks 3 are welded at equal intervals on the rear of the inner wall of the C-shaped frame 4. Horizontal bars 5 are welded between the weld blocks 3, and multiple sets of support plates 7 are installed between the horizontal bars 5. Connecting bolts 6 are used to fix the support plates 7 to the horizontal bars 5. The support column 2 is fixedly connected to the weld blocks 3 by welding. At the same time, wing plates 1 extend laterally from the top and bottom of the support column 2. The C-shaped frame 4 bears the overall longitudinal force. The horizontal bars 5 and the support plates 7 form lateral and vertical constraints, making the open part of the C-shaped frame 4 less prone to lateral warping and enhancing the bending stiffness of the section. The addition of the support column 2 and wing plates 1 effectively disperses the external load within the component, preventing local deformation caused by concentrated loads. This allows the special C-shaped steel component to remain stable under large span or high load conditions, not only improving the load-bearing capacity but also reducing the need for subsequent reinforcement procedures and shortening the installation period.

[0019] A base plate 9 is fixedly connected to the bottom end of the wing plate 1. A slot 10 is machined on the edge of the mating surface between the wing plate 1 and the base plate 9. An inner support 11 is embedded in the wing plate 1. An outer support 12 is welded to the right side of the inner support 11. The edge of the outer support 12 is aligned with the base plate 9. An outer bolt 13 is fixedly connected between the outer support 12 and the base plate 9. An inner bolt 14 is fixedly connected between the inner support 11 and the wing plate 1. The inner support 11 and the outer support 12 are arranged in opposite directions to form relative force. The edge of the wing plate 1 is in contact with the inner wall of the inner support 11. Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a base plate 9 is fixed to the bottom of the C-frame 4. A slot 10 is machined on the edge of the mating surface between the wing plate 1 and the base plate 9. An inner support 11 is embedded in the slot 10. An outer support 12 is welded to the right side of the inner support 11. The edge of the outer support 12 is aligned with the base plate 9 and is fixedly connected to the base plate 9 by an outer bolt 13. At the same time, the inner support 11 and the wing plate 1 are fixed by an inner bolt 14. The inner support 11 and the outer support 12 form a back-to-back tension structure, similar to a pair of symmetrically arranged hinge points. This structure can transmit vertical loads and offset the additional stress caused by lateral offset. The stress state is more uniform, avoiding the problem of loosening or cracking caused by excessive stress on one side of the connecting parts. This enhances the stability of the bottom of the component, ensures the overall stress balance, and reduces maintenance costs.

[0020] The bottom of the inner wall of the C-frame 4 is welded to the surface of the base plate 9, and the inner support 8 is set accordingly. Specifically, such as Figure 1 As shown, multiple sets of inner supports 8 are welded to the bottom of the C-shaped frame 4 and the surface of the base plate 9 to form point support. The welded connection between the C-shaped frame 4 and the base plate 9 provides overall rigidity, while the point support of the inner supports 8 allows local loads to be transferred to the base plate 9 through multiple stress points, thereby effectively dispersing stress concentration. The inner supports 8 act like "bridge piers", reducing the risk of warping or denting of the base plate 9. Uniform stress can be achieved without the need for additional complex reinforcements. The construction process is simple, the construction period can be shortened, and the long-term stability of special C-shaped steel components in actual projects can be guaranteed.

[0021] Working principle: This special C-shaped steel component mainly relies on two sets of parallel C-shaped frames 4 as the main load-bearing components. Welded blocks 3, crossbars 5 and support plates 7 form a stable frame in the transverse and longitudinal directions through connecting bolts 6, which improves the overall bending and shear resistance. Wing plates 1 and columns 2 jointly distribute the external load and avoid local stress concentration. In the bottom structure, the inner support 11 and the outer support 12 are fixed by the inner bolts 14 and the outer bolts 13, which enhances the stress balance at the bottom. The inner support legs 8 provide point support, so that the load is evenly transferred to the bottom plate 9, effectively reducing the risk of warping or deformation. The overall structure shortens the processing steps while ensuring rigidity, and improves the stability of installation and long-term use.
