Technical Field

[0001] The present application relates to the field of I-beams, and in particular to an I-beam with an end closing box. Background Art

[0002] I-beams, because of their I-shaped cross-section, are widely used in many fields, mainly as load-bearing components. I-beams are often used as beam-column components, stair handrails, door and window frames, and floor supports in building structures. Their stable structure and good load-bearing capacity make them an indispensable material in construction projects. In bridge construction, I-beams can be used for beam-type support components, bridge deck beams, and other parts. Their high strength and rigidity can effectively support the deadweight of the bridge and vehicle loads, ensuring the safety and stability of the bridge. I-beams are also widely used in the field of machinery manufacturing, such as for the manufacture of supporting components, transmission shafts, brackets, and other parts in various mechanical equipment and industrial facilities. They have regular shapes and precise dimensions, making them easy to process and install.

[0003] In the related art, the cross-section of the I-beam is in the shape of an "I", with supports set on both sides and vertical stiffening ribs set at the supports. Its obvious defect is that it is very easy to cause lateral buckling instability under the action of vertical loads, and lose bearing capacity, resulting in safety accidents. Summary of the invention

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The embodiment of the present application provides an I-beam with an end closed box, which can solve the technical problem that traditional I-beams are very likely to suffer from lateral buckling instability under vertical loads, lose bearing capacity and cause safety accidents.

[0025] like Figure 1 , Figure 3 or Figure 5 As shown, an embodiment of the present application provides an I-beam with an end closure box, which includes: an I-beam body 1, the I-beam body 1 includes two wing plates 11 and a web 12 fixed between the two wing plates 11; an end closure box 2, along the length direction of the web 12, the end closure box 2 is located at one end of the web 12 and fixed between the two wing plates 11, and the groove of the end closure box 2 faces the side wall of the web 12.

[0026] In this embodiment, the I-beam body 1 is composed of two wing plates 11 and a web 12 fixed between the two wing plates. This structure maintains the basic shape and mechanical properties of the I-beam. Along the length direction of the web 12, the end closing box 2 is located at one end of the web and fixed between the two wing plates 11. The notch of the end closing box 2 faces the side wall of the web 12, forming a closed structure. The design of the end closing box 2 enhances the structural rigidity and stability of the I-beam at the end, especially when subjected to vertical loads, it can effectively prevent lateral buckling instability. The design of the end closing box 2 significantly enhances the structural rigidity and stability of the I-beam at the end. By closing the structure at one end of the web 12, the risk of lateral buckling of the I-beam under vertical load is reduced, thereby improving the bearing capacity and safety performance of the overall structure. Traditional I-beams are prone to lateral buckling instability under vertical loads, resulting in loss of bearing capacity and safety accidents. The modified technical solution effectively prevents this situation from happening by adding the end closing box 2, reducing the risk of safety accidents. The close combination of the end closure box 2 and the I-beam body 1 enhances the integrity of the I-beam. This structure can better disperse stress when subjected to external forces, thereby improving the overall stability and durability of the structure. The modified I-beam has higher stability and bearing capacity, making it suitable for a variety of scenarios that need to withstand large vertical loads, such as building structures, bridge projects, etc. In summary, the modified technical solution effectively solves the problem of lateral buckling instability that is prone to occur in traditional I-beams under vertical loads by adding an end closure box 2, thereby improving the stability and bearing capacity of the I-beam, reducing the risk of safety accidents, and enhancing the integrity and durability of the structure.

[0027] In one embodiment, there are two end closure boxes 2, which are located on the same side of the web 12 and distributed at both ends of the web 12 along the length direction of the web 12, and the end closure boxes 2 are fixed between the two wing plates 11.

[0028] In this embodiment, there are two end closure boxes 2, which are located on the same side of the web 12 and are fixed to the two ends of the web 12 along the length direction of the web 12. The two end closure boxes 2 are fixed between the two wing plates 11 to form a stable overall structure with the I-beam body 1. By arranging the end closure boxes 2 at the two ends of the web 12, the two ends of the I-beam are double-reinforced. This design not only improves the stability of the I-beam under vertical load, but also further reduces the risk of lateral buckling instability. The arrangement of the two end closure boxes 2 helps to more evenly disperse the stress generated by external force on the I-beam, avoiding structural damage caused by stress concentration. This improves the bearing capacity and durability of the I-beam. The double-end closed structure significantly improves the overall stiffness of the I-beam, so that it can maintain better shape stability and structural integrity when subjected to external force. Since both ends are reinforced, this I-beam is more adaptable to complex load conditions and changing use environments, such as dynamic loads or combined loads.

[0029] In one embodiment, the number of the end closure boxes 2 is two, the two end closure boxes 2 are located on opposite sides of the web 12, and are distributed at both ends of the web 12 along the length direction of the web 12, and the end closure boxes 2 are fixed between the two wing plates 11.

[0030] In this embodiment, the number of the end closing boxes 2 is two, and the two end closing boxes 2 are not located on the same side of the web 12, but are located on opposite sides of the web 12, that is, one is located at one end of the web 12, and the other is located at the other end of the web 12. The two end closing boxes 2 are fixed between the two wing plates 11 by welding to ensure that they form a stable and continuous integral structure with the I-beam body 1. Since the end closing boxes 2 are located on both sides of the web 12, this design realizes the two-way reinforcement of both ends of the I-beam. This helps to more comprehensively improve the stability and bearing capacity of the I-beam under the action of vertical loads or external forces in other directions. The arrangement of the two end closing boxes 2 on both sides of the web 12 helps to balance the stress distribution generated by external forces on the I-beam. This balancing effect can reduce stress concentration and local deformation, thereby improving the overall durability and safety of the structure. The end closing boxes 2 are arranged on both sides of the web 12 to enhance the torsion resistance of the I-beam. When the I-beam is subjected to torque, this design can better resist torsional deformation and maintain the stability of the structure. Since both ends are reinforced in a symmetrical manner, this type of I-beam can better adapt to a variety of complex load conditions and changing usage environments. It can provide stable support regardless of static or dynamic loads.

[0031] In one embodiment, Figure 2 , Figure 4 or Figure 6As shown, there are two end closing boxes 2 , which are located on opposite sides of the web 12 and spaced apart along the thickness direction of the web 12 , and are fixed between the two wing plates 11 .

[0032] In this embodiment, the number of the end closing boxes 2 is two. Different from the previous description, the two end closing boxes 2 are not distributed at the two ends of the web 12 along the length direction of the web 12, but are located on the opposite sides of the web 12, and the two closing boxes are spaced apart along the thickness direction of the web 12 (i.e., the direction perpendicular to the plane of the web 12). The two end closing boxes 2 are fixed between the two wing plates 11 by welding to ensure that they form a stable and continuous whole with the I-beam body 1. Since the end closing boxes 2 are located on both sides of the web 12 and spaced apart along the thickness direction, this design effectively enhances the structural stability of the I-beam in the thickness direction. When the I-beam is subjected to external forces, this layout can better resist deformation and buckling. The presence of the two end closing boxes 2 increases the cross-sectional area and moment of inertia of the I-beam, thereby improving its bearing capacity. This design enables the I-beam to withstand a larger load without damage. The spaced distribution of the end closing boxes 2 helps to optimize the stress distribution of external forces on the I-beam. They can disperse stress concentration points and reduce local excessive stress, thereby improving the overall durability of the structure. Since the end closure boxes 2 are located on both sides of the web 12 and distributed along the thickness direction, this design enhances the torsion and bending resistance of the I-beam. When the I-beam is subjected to torque or bending moment, this layout can better maintain the stability of the structure.

[0033] In one embodiment, Figure 1 , Figure 3 or Figure 5 As shown, the number of the end closing boxes 2 is four, two of the end closing boxes 2 are located on opposite sides of the web 12 and at the same end of the web 12, and the two end closing boxes 2 are fixed between the two wing plates 11, and the other two end closing boxes 2 are located on opposite sides of the web 12 and at the other same end of the web 12, and the other two end closing boxes 2 are fixed between the two wing plates 11.

[0034] In this embodiment, the number of the end closure boxes 2 is four, two of which are located on opposite sides of the web 12, and are located at the same end of the web 12 (for example, the left end or the right end). The other two end closure boxes 2 are also located on opposite sides of the web 12, but they are located at the other same end of the web 12 (i.e., the other end opposite to the previous two closure boxes). All four end closure boxes 2 are fixed between the two wing plates 11 by welding to ensure that a stable and continuous overall structure is formed with the I-beam body 1. Since the end closure boxes 2 are provided on both sides and both ends of the web 12, this design realizes four-way reinforcement of the I-beam, which greatly improves the stability and bearing capacity of the I-beam in multiple directions. The presence of the four end closure boxes 2 makes the stress distribution of the external force on the I-beam more uniform, and they can effectively disperse the stress concentration points and avoid structural damage caused by excessive local stress. The end closure boxes 2 are arranged on both sides and ends of the web 12, which greatly enhances the torsion and bending resistance of the I-beam. This layout can maintain the stability of the structure no matter what direction the torque or bending moment is applied to the I-beam. The four end closure boxes 2 form a solid whole with the web 12 and the wing plate 11, which significantly improves the overall stiffness of the I-beam, which enables the I-beam to maintain better shape stability and structural integrity when subjected to external forces. Due to the four-way reinforced design, this I-beam is more adaptable to extreme load conditions and changing use environments. Whether it is static load, dynamic load or combined load, it can provide stable support.

[0035] In one embodiment, Figure 2 As shown, the end closing box 2 is arranged in a concave shape.

[0036] In this embodiment, the concave end closure box 2 has an inwardly recessed portion on the side wall facing the web 12. This design allows the end closure box 2 to better fit with the surrounding structure, reduce space occupancy, and enhance structural stability.

[0037] In one embodiment, Figure 4 As shown, the end closing box 2 is arranged in an arc shape.

[0038] In this embodiment, the arc-shaped end closure box 2 has a smooth curve shape. This design is not only beautiful, but also can reduce stress concentration and improve the durability of the structure. It is suitable for scenes that need to reduce stress concentration, improve structural aesthetics, or need to cooperate with other arc-shaped components. For example, in structures such as bridges and buildings, the arc design can make the entire structure more smooth and harmonious.

[0039] In one embodiment, Figure 6 As shown, the end closing box 2 is arranged in a V shape.

[0040] In this embodiment, in scenarios where a large impact force needs to be withstood or force flow needs to be guided to reduce structural stress, the V-shaped setting can provide better mechanical properties and stability. For example, in earthquake-resistant structures, the V-shaped design helps to disperse seismic forces and reduce structural damage.

[0041] In one embodiment, Figure 2 , Figure 4 and Figure 6 As shown, along the length direction of the web 12, notches 21 are provided at both ends of the notch of the end closure box 2. With the advancement of welding and processing technology, the notches 21 can also be omitted.

[0042] In this embodiment, the end closure box 2 is provided with notches 21 at both ends of the notch along the length direction of the web 12. Providing the notches in the length direction of the web 12 allows the end closure box 2 to be more conveniently matched with other structures when connected or installed with other components, thereby improving the efficiency and accuracy of installation. Secondly, the design of the notches 21 can also provide a certain deformation space for the end closure box 2, thereby improving its impact resistance and durability.

[0043] In one embodiment, the end closing box 2 is provided with reinforcing ribs inside, and the reinforcing ribs are arranged in a transverse, longitudinal or mesh manner.

[0044] In this embodiment, the interior of the end-capped closed box 2 can be provided with reinforcing ribs, which can be arranged in a horizontal, longitudinal or meshed manner. Such a design is mainly to enhance the structural strength and stability of the end-capped closed box 2 and improve its bearing capacity and impact resistance. Specifically, the arrangement of the reinforcing ribs can effectively disperse the stress of the end-capped closed box 2 when it is subjected to force, and avoid structural damage caused by stress concentration. At the same time, the reinforcing ribs can also increase the rigidity of the end-capped closed box 2, so that it can maintain better shape stability when facing external impact or pressure. When the reinforcing ribs are arranged in a horizontal manner, they can be distributed along the width direction of the end-capped closed box 2, providing a lateral support force for the box body, and enhancing its bending resistance in this direction. When the reinforcing ribs are arranged in a longitudinal manner, they extend along the length direction of the end-capped closed box 2, providing a longitudinal support force for the box body, which helps to improve its bearing capacity and stability in this direction. When the reinforcing ribs are arranged in a meshed manner, they will be interwoven into a dense grid, covering the interior of the end-capped closed box 2. This design can not only provide all-round support, but also further enhance the overall strength and stability of the box body.
