Description

Technical Field

[0001] This invention relates to the field of building components, and in particular to a corbel box column with external bracing and armhole reinforcement. Background Technology

[0002] A corbel box column is a crucial load-bearing and force-transferring component in modern steel structure engineering. It consists of a box column as the main vertical support and a corbel as a cantilever support platform. With its closed rectangular cross-section, the box column has extremely high resistance to compression, bending, and torsion, providing stable support for the overall structure. The corbel, on the other hand, acts as a cantilever member extending from the column, reliably bearing and transmitting huge loads from secondary beams, crane beams, or equipment platforms.

[0003] In existing steel structure engineering, the column body and corbel of a bracket box column are typically connected by a single welding method. This connection method has the following significant drawbacks: First, under load, stress is highly concentrated at the weld joint between the corbel and the column, forming a significant stress concentration zone, posing a considerable risk of fatigue failure and affecting structural safety. Second, the force transmission between the column and the corbel relies mainly on the weld joint, resulting in weak overall integration and poor collaborative performance, leading to a need to improve the stiffness and stability of the structure. Summary of the Invention

[0004] Technical problems to be solved

[0005] The core of this invention lies in solving the problems of weak overall integrity, poor rigidity and stability of the column and corbel in the prior art by using the corbel web plate and the outer support plate that penetrate the box-shaped column body.

[0006] Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0009] The corbel body includes a corbel web plate that runs through the box-shaped column body and is fixedly connected to the left box plate and the right box plate. The box plate is fixedly connected to the corbel web plate perpendicularly. An outer support plate is fixedly connected to the outer end of the corbel web plate away from the box-shaped column body. Multiple horizontal stiffening plates are fixedly connected between the outer support plate and the outer wall of the box-shaped column body. The inner end of the horizontal stiffening plate is fixedly connected to the outer wall of the corbel web plate. A vertical stiffening plate is fixedly connected between the multiple horizontal stiffening plates. The inner end of the vertical stiffening plate is fixedly connected to the outer wall of the corbel web plate.

[0010] The outer support plate includes an integrally formed upper vertical part, an inner bending part, and a lower vertical part. The upper and lower vertical parts are both arranged parallel to the box column body. The inner bending part is inclined inward. A haunch is provided at the connection between the horizontal stiffening plate and the box column body. The haunch is a long strip structure with a triangular cross-section and is integrally formed with the horizontal stiffening plate.

[0011] As a further improvement of the present invention, a pair of symmetrically arranged upper sealing plates of the corbel are fixedly connected to the upper end of the outer support plate. The end of the upper sealing plate of the corbel away from the outer support plate is fixedly connected to the outer wall of the box-shaped column body, and its inner edge is fixedly connected to the outer wall of the corbel web plate.

[0012] As a further improvement of the present invention, a central positioning groove is provided at the center of the upper part of the cow leg belly plate, and a central vertical slot that cooperates with the central positioning groove is provided at the lower part of the box belly plate.

[0013] As a further improvement of the present invention, the cow leg belly plate is provided with symmetrically arranged side positioning grooves on both sides of the central positioning groove, and the lower part of the left box plate and the right box plate are provided with side vertical slots that cooperate with the side positioning grooves.

[0014] As a further improvement of the present invention, multiple horizontal positioning grooves are provided at both ends of the cow leg belly plate, and a horizontal slot that cooperates with the horizontal positioning grooves is provided in the middle of the horizontal stiffening plate.

[0015] As a further improvement of the present invention, the vertical stiffening plate is provided with a plurality of in-plate slots, and the horizontal stiffening plate is provided with an in-plate positioning groove that cooperates with the in-plate slots, and the in-plate positioning groove is connected to the horizontal slot.

[0016] As a further improvement of the present invention, a positioning block is fixedly connected to the lower side wall of the cow leg belly plate, and a side insertion hole for the positioning block to pass through is opened at the lower part of the outer support plate.

[0017] As a further improvement of the present invention, an inner insertion hole is provided at the lower part of the cow leg belly plate, and an outer insertion hole is provided at the lower part of both the front box plate and the rear box plate, which is opposite to the inner insertion hole.

[0018] Beneficial effects

[0019] Compared with the prior art, the advantages of this invention are:

[0020] (1) The present invention replaces the traditional single welding connection method with a corbel web plate that penetrates through the box column body and is fixedly connected to the box web plate, thereby enhancing the connection stiffness and integrity between the corbel body and the box column body, expanding the force transmission interface, making the force distribution more uniform, overcoming the problem that the force of the traditional corbel box column is concentrated at the weld seam, and improving the overall load-bearing capacity; in addition, the design of the inner bend makes the outer support plate form an oblique support, effectively enhancing the stability of the corbel cantilever end and further improving its load-bearing performance; in addition, the haunch set at the connection between the horizontal stiffening plate and the box column body effectively improves the local stiffness and load-bearing capacity of the area, integrating three structural reinforcement methods of haunch, stiffening and outer support, improving the structural stiffness and load capacity of the corbel box column.

[0021] (2) The present invention adopts the method of first plugging and then welding, so that the left box plate, right box plate, box web plate, horizontal stiffening plate and corbel web plate are nested together. Compared with the traditional simple welding connection method, it realizes mechanical interlock between the connecting plates and increases the force transmission area between them, overcomes the problem that the force points of the traditional welding connection method are too concentrated at the weld seam, and further improves the connection stability and load capacity of the box column body and the corbel body. In addition, by opening multiple positioning grooves on the corbel web plate, the rapid positioning and splicing of each plate can be realized, reducing the installation difficulty and improving the installation efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] Please see Figures 1-4In one embodiment of the present invention, an externally supported and reinforced corbel box column includes a box column body and a corbel body. The box column body includes a left box plate 1, a right box plate 2, a front box plate 3, and a rear box plate 4, which are fixedly fixed end to end. A box web plate 5 is fixedly connected between the front box plate 3 and the rear box plate 4. The corbel body includes a corbel web plate 6 that penetrates the box column body and is fixedly connected to the left box plate 1 and the right box plate 2. The box web plate 5 is vertically fixedly connected to the corbel web plate 6. An external support plate 7 is fixedly connected to the outer end of the corbel web plate 6 away from the box column body. A plurality of horizontal stiffening plates 8 are fixedly connected between the external support plate 7 and the outer wall of the box column body. The inner end of the horizontal stiffening plate 8 is fixedly connected to the outer wall of the corbel web plate 6. A vertical stiffening plate 9 is fixedly connected between the plurality of horizontal stiffening plates 8. The inner end of the vertical stiffening plate 9 is fixedly connected to the outer wall of the corbel web plate 6.

[0037] Please see Figure 3 and Figure 4 The outer support plate 7 includes an integrally formed upper vertical part 701, an inner bending part 702, and a lower vertical part 703. The upper vertical part 701 and the lower vertical part 703 are both arranged parallel to the box column body. The inner bending part 702 is inclined inward. The horizontal stiffening plate 8 is provided with a haunch 803 at the connection between it and the box column body. The haunch 803 is a long strip structure with a triangular cross section. The haunch 803 is integrally formed with the horizontal stiffening plate 8.

[0038] Specifically, the corbel web 6 penetrates the box-shaped column body and is fixedly connected to the box web 5 located inside it, thereby enhancing the connection stiffness and integrity between the corbel body and the box-shaped column body, expanding the force transmission interface, making the force distribution more uniform, and improving the overall load-bearing capacity. In addition, the design of the inner bend 702 makes the outer bracing plate 7 form an oblique support, effectively enhancing the stability of the corbel cantilever end and further improving its load-bearing performance. Furthermore, the haunch 803 set at the connection between the horizontal stiffening plate 8 and the box-shaped column body effectively improves the local stiffness and load-bearing capacity of this area.

[0039] Please see Figure 1 A pair of symmetrically arranged upper bracket sealing plates 10 are fixedly connected to the upper end of the outer support plate 7. The end of the upper bracket sealing plate 10 away from the outer support plate 7 is fixedly connected to the outer wall of the box column body, and its inner edge is fixedly connected to the outer wall of the bracket web plate 6.

[0040] Specifically, the connection stability between the outer support plate 7 and the box column body is further improved by using two pairs of corbel sealing plates 10.

[0041] In another embodiment of the invention, please refer to Figures 5-7A central positioning groove 601 is provided at the upper center of the cow leg web plate 6, and a central vertical slot 501 that mates with the central positioning groove 601 is provided at the lower part of the box web plate 5. When installing the box web plate 5, the central vertical slot 501 of the box web plate 5 and the central positioning groove 601 of the cow leg web plate 6 are interlocked.

[0042] Specifically, by interlocking the box web 5 and the corbel web 6, the positions of the box web 5 and the corbel web 6 can be quickly located. At the same time, compared with the traditional simple welding connection method, the method of interlocking and then welding makes the box web 5 and the corbel web 6 nested together, realizing mechanical interlocking and increasing the stress transmission area of ​​the two. This overcomes the problem that the stress point of the traditional welding connection method is too concentrated at the weld seam, and further improves the connection stability and load-bearing capacity of the box column body and the corbel body.

[0043] Please see Figures 5-7 The cow leg belly plate 6 has symmetrically arranged side positioning grooves 602 on both sides of the central positioning groove 601, and the lower part of the left box plate 1 and the right box plate 2 are provided with side vertical slots 101 that cooperate with the side positioning grooves 602.

[0044] Specifically, during the installation of the left box panel 1 and the right box panel 2, the installation position is quickly positioned using the side positioning groove 602. Then, the side vertical slots 101 of the left box panel 1 and the right box panel 2 are aligned with the side positioning groove 602 and inserted, thereby achieving rapid positioning and installation of the left box panel 1 and the right box panel 2. After installation, the left box panel 1 and the right box panel 2 are mechanically interlocked with the corbel web plate 6, improving the connection stability and load transfer capacity of the two.

[0045] Please see Figure 7 Multiple horizontal positioning grooves 603 are provided at both ends of the cow leg web plate 6, and a horizontal slot 801 that cooperates with the horizontal positioning grooves 603 is provided in the middle of the horizontal stiffening plate 8.

[0046] Specifically, when installing the horizontal stiffening plate 8, the horizontal slot 801 is inserted into the horizontal positioning slot 603 to achieve rapid assembly, which facilitates subsequent welding operations. At the same time, the method of inserting first and then welding is adopted to reduce the use of clamping and fixing auxiliary devices and improve the efficiency of splicing and welding.

[0047] Please see Figures 7-10 The vertical stiffening plate 9 has multiple slots 901, and the horizontal stiffening plate 8 has an internal positioning groove 802 that mates with the slots 901. The internal positioning groove 802 is connected to the horizontal slot 801.

[0048] Specifically, it facilitates the rapid splicing and welding of the vertical stiffening plate 9 and the horizontal stiffening plate 8, and achieves mechanical interlocking between the two through plug-in connection, thereby improving connection stability and load capacity.

[0049] Please see Figure 7 A positioning block 11 is fixedly connected to the lower side wall of the cow leg belly plate 6, and a side insertion hole 704 is opened at the lower part of the outer support plate 7 for the positioning block 11 to pass through.

[0050] Specifically, the positioning block 11 and the side insertion hole 704 are used to quickly position the outer support plate 7, which facilitates subsequent welding and fixing operations and enhances the connection stability between the outer support plate 7 and the corbel web plate 6.

[0051] Please see Figure 1 , Figure 5 and Figure 6 The lower part of the cow leg belly plate 6 is provided with an inner insertion hole 604, and the lower parts of the front box plate 3 and the rear box plate 4 are provided with an outer insertion hole 301 opposite to the inner insertion hole 604. An insert strip 12 is inserted into the inner insertion hole 604 and extends to the outside of the outer insertion hole 301.

[0052] Specifically, the lower part of the box column body and the corbel web 6 are connected and fixed by the insert strip 12, which further improves the stability of the connection between the box column body and the corbel body and improves the uniformity of load transmission.

[0053] Compared to the traditional simple welding connection method, this invention adopts a method of first inserting and assembling and then welding, so that the left box plate 1, right box plate 2, box web plate 5, horizontal stiffening plate 8 and corbel web plate 6 are nested with each other to achieve mechanical interlocking and increase the force transmission area of ​​the two. This overcomes the problem that the force points of the traditional welding connection method are too concentrated at the weld seam, and further improves the connection stability and load-bearing capacity of the box column body and the corbel body. In addition, by opening multiple positioning grooves on the corbel web plate 6, the various plates can be quickly positioned and spliced, reducing the installation difficulty and improving the installation efficiency.

[0054] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
