Description

Technical Field

[0001] The utility model relates to the field of I-beams, in particular to a flange-reinforced I-beam. Background Art

[0002] I-beams, also known as steel beams, are long strips of steel with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. I-beams are steel with an I-shaped cross section. Whether ordinary or light, I-beams have relatively high and narrow cross-sectional dimensions, so the moments of inertia about the two main axes of the cross section differ greatly. Therefore, they can only be directly used for members that are bent within the plane of their webs or to form lattice-type load-bearing members. I-beams are widely used in buildings or other metal structures.

[0003] The existing I-beam structure is simple, and the upper flange is prone to wrinkle and buckle when under pressure, which leads to increased deflection of the steel beam, thereby causing local buckling of the web, and finally causing the entire steel beam to buckle or overturn and twist and deform until it is destroyed.

[0004] The technical problem to be solved by the present application is: how to strengthen the flange structure of the I-beam to enhance its overall stability. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model aims to provide a flange-reinforced I-beam with strong bearing capacity and stable structure.

[0006] The technical solution adopted by the utility model is: a flange reinforced I-beam, including an upper flange and a lower flange, a web is fixed between the upper flange and the lower flange, a reinforcing beam matched with the upper flange and the lower flange is also provided between the upper flange and the lower flange, a first limiting piece is fixed to both the upper flange and the lower flange, a second limiting piece connected to the first limiting piece is fixed to the top of the reinforcing beam, two reinforcing beams are provided and are symmetrically arranged about the web, a supporting beam is provided between the two reinforcing beams, the reinforcing beam is provided with an installation column matched with the supporting beam for limiting, the supporting beam passes through the web and fits tightly with the web.

[0007] In some embodiments, a limiting groove is defined in the first limiting member, and the second limiting member is located in the limiting groove and slidably cooperates with the limiting groove.

[0008] In some embodiments, the second side plates are fixed on both sides of the first limiting member, and the first side plates are fixed on both sides of the second limiting member, and the cross-sectional sizes of the first side plate and the second side plate are the same.

[0009] In some embodiments, the first side plate and the second side plate are respectively provided with a first nail groove and a second nail groove which are arranged at corresponding positions, and the first side plate is provided with a bolt which is screwed to the first nail groove and the second nail groove at the same time.

[0010] In some embodiments, the mounting column is provided with two mounting slots, and the support beam matches the mounting slots in shape and size.

[0011] In some embodiments, a through groove is formed in the web, and the outer wall of the support beam is closely fitted with the inner wall of the through groove.

[0012] In some embodiments, the top of the upper flange is arc-shaped.

[0013] In some embodiments, there are chamfer structures between the upper flange and the web, and between the lower flange and the web.

[0014] The beneficial effects of the utility model are as follows: the structural stability between the upper flange and the lower flange is guaranteed by the reinforcing beam arranged between the upper flange and the lower flange, and the load-bearing capacity thereof is greatly enhanced; by the coordinated arrangement of the mounting column, the supporting beam and the web, when the two sides of the upper flange are subjected to force, the pressure acts on the outer surface of the upper flange, and can act on the reinforcing beams on both sides of the upper flange, and the upper flange is supported by the reinforcing beam, and at the same time, the pressure can be dispersed to the supporting beam through the reinforcing beam, and the pressure on both sides of the upper flange is shared and balanced by the supporting beam, thereby avoiding as much as possible the problem that the existing I-beam structure is simple, the upper flange is prone to wrinkle and buckle when subjected to pressure, resulting in increased downward deflection of the steel beam, thereby causing local buckling of the web, and finally causing the entire steel beam to buckle or overturn, twist and deform, and even be destroyed.
