[0025] As Figure 1 , Figure 2The embodiment of the present application provides a kind of H-shaped steel section, including web 1 and parallelly arranged flange plate 2 on its two sides, the angle position between web 1 and flange plate 2 is provided with reinforcing member 3, reinforcing member 3 includes two inclined surfaces, the tip of the intersection of two inclined surfaces is towards the junction of web 1 and flange plate 2, two inclined surfaces respectively extend from the tip to the opening position of the junction of flange plate 2 and web 1, slot is opened in the side of reinforcing member 3 away from web 1;

[0026] Reinforcing member 3 is connected to the right angle position of web 1 and flange plate 2, which can effectively improve the compressive strength and rigidity of web 1 and flange plate 2, and plays a reinforcing role;

[0027] Reinforcing member 3 is designed with two inclined surfaces, which keep a certain angle between the inclined surfaces and web 1 and flange plate 2, so that reinforcing member 3 can be easily connected with web 1 or flange plate 2 by welding;

[0028] The slot of reinforcing member 3 can increase the length of weld, increase the welding position, and provide good structural stability, and improve the connection strength of reinforcing member 3 and H-shaped steel.

[0029] In the embodiment, as shown in Figures 2-4 The first end of reinforcing member 3 is attached to flange plate 2, and the second end of reinforcing member 3 is attached to web 1;

[0030] The two ends of reinforcing member 3 are attached to flange plate 2 and web 1 respectively, so that the contact area is large, the contact position has large span, the structural stability is strong, and the load and connection strength are high.

[0031] The angle between the two inclined surfaces of reinforcing member 3 is 30-60°;

[0032] The angle between the inclined surface of reinforcing member 3 and web 1 and flange plate 2 ensures easy welding, and ensures that the inside of the "V"-shaped slot of reinforcing member is easy to weld.

[0033] Reinforcing member 3 is arranged at intervals on web 1;

[0034] Reinforcing member 3 is arranged at intervals to ensure that there is a welding operation space between two adjacent reinforcing members 3, while maintaining good structural strength.

[0035] The first end edge of reinforcing member 3 is flush with the side wall of flange plate 2;

[0036] Reinforcing member 3 can effectively transmit the pressure of the edge part of flange plate 2 to web 1, thereby playing a good reinforcing and supporting role.

[0037] The connection between the two inclined surfaces of reinforcing member 3 is a circular arc angle;

[0038] Avoid too small included angle causes uneven load distribution and stress concentration problem, using smooth transition arc surface can effectively reduce the bending phenomenon of reinforcing member 3.

[0039] The inclined wall surface of the reinforcing member 3 is provided with a circular arc protrusion;

[0040] Through the circular arc protrusion, the length of the weld is further increased, and at the same time the thickness of the reinforcing member 3 is increased, thereby strengthening the structural strength of the reinforcing member 3.
