Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a high-strength welded H-shaped steel. Background Art

[0002] In buildings such as factories, the skeleton is made of structural materials such as steel. As such structural materials, H-shaped steel is usually used from the perspective of bending rigidity or bending strength. H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings, and light structural weight, and has been widely used. However, in actual use, the connection between the web and flange of the H-shaped steel is currently made by contact welding. The stability of the connection between the web and flange depends entirely on the welding strength of the welding point. Therefore, the torsional strength of the flange-to-web weld is not high. When the force on both sides of the flange is uneven, the weld between the web and flange is prone to desoldering, which can easily cause the flange and web of the H-shaped steel to fall apart and separate.

Through the arrangement of the reinforcing ribs 4 and the positioning pressure plates 5, the force exerted on the flange 2 by the web 1 is increased. The balancing inner support slide plate 8 is provided on the surface of the wing plate 2, and the side slide groove used to cooperate with the balancing inner support slide plate 8 is provided. The surface of the balancing inner support slide plate 8 is slidably connected to the inner wall of the side slide groove provided on the surface of the wing plate 2. Through the setting of the balancing inner support slide plate 8, the connection strength of the reinforcing rib 4 and the positioning pressure plate 5 and the wing plate 2 is strengthened, so that the stability of the welded H-shaped steel is better. The side of the positioning pressure plate 5 away from the reinforcing rib 4 is fixedly connected to the welding plate 6, and the right side of the welding plate 6 is welded with a longitudinal welding block 7. The side of the welding plate 6 is fixedly welded to the surface of the wing plate 2 through the longitudinal welding block 7. A plurality of welding slot holes 9 are provided on the middle surface of the wing plate 2. The slot holes 9 are symmetrically distributed front and back in the middle of the wing plate 2, and the interval distance between two adjacent welding slot holes 9 is set to between 10 cm and 15 cm. Through the multiple symmetrical welding slot holes 9 set on the surface of the wing plate 2, the pressure-resistant stable pin 10 is inserted into the high-strength pressure-resistant convex plate 3 card hole located in the slide groove of the wing plate 2, and the web 1 and the wing plate 2 are slidably displaced and spliced ​​and fixed, and the connection between the web 1 and the wing plate 2 is firmly locked by spot welding the welding point block 14 in the welding slot hole 9. A welding top plate 11 is placed inside the welding slot hole 9, and a pressure-resistant stable pin 10 is fixedly connected to the surface of the welding top plate 11. A plurality of docking holes for cooperating with the pressure-resistant stable pin 10 are opened on the surface of the high-strength pressure-resistant convex plate 3.

The surface of the built-in rotating block 12 is clamped in the welding slot hole 9 of the wing plate 2. Two vertical slide bars 13 for use with the built-in rotating block 12 are provided in the welding slot hole 9 of the wing plate 2. Through the setting of the built-in rotating block 12 and the vertical slide bar 13, the built-in rotating block 12 is slidably displaced from the vertical slide bar 13 to the welding slot hole 9 of the wing plate 2, and then the built-in rotating block 12 is clamped in the welding slot hole 9 by the rotation of the welding top plate 11.This increases the stability of the pressure-resistant stable pin 10 inserted into the high-strength pressure-resistant convex plate 3, ensuring that the sliding installation and clamping of the web 1 and the wing plate 2 are more stable.

At this time, the ends of the pressure-resistant stabilizing pins 10 are inserted into the clamping holes of the high-strength pressure-resistant convex plates 3, and then the welding top plate 11 is rotated so that the built-in rotating blocks 12 on both sides of the welding top plate 11 are rotated to the positions corresponding to the drawings. Figure 5 The state is sufficient. At this time, the built-in rotating blocks 12 on both sides of the welding top plate 11 are stuck in the welding slot holes 9 set in the wing plate 2 and cannot be pulled out. Then, spot welding (welding spot blocks 14) can be carried out in the welding slot holes 9 opened on the surface of the wing plate 2 in turn, so that the end of the pressure-resistant stable pin 10 is completely fixed on the high-strength pressure-resistant convex plate 3, and then the longitudinal full welding at the position of the longitudinal welding block 7 is used to fix the welding plate 6 to the wing plate 2. Therefore, the connection between the top and bottom wing plates 2 and the web 1 is greatly improved in terms of anti-torque strength and load stability during actual use. At the same time, the contents not described in detail in this specification belong to the existing technology well known to professional and technical personnel in this field.

The high-strength pressure-resistant convex plate 3 is inserted into the card hole of the pressure-resistant convex plate 3, and the welding point blocks 14 are spot-welded in the multiple welding slot holes 9 of its wing plate 2 to fix the high-strength pressure-resistant convex plate 3 inserted into the slide groove of the wing plate 2. Then, the force strength is increased by the reinforcing ribs 4 arranged on both sides of the contact surface between the web 1 and the wing plate 2, and the welding plate 6 is fixedly welded to the wing plate 2 through longitudinal full welding at the position of the longitudinal welding block 7, so that the connection between the top and bottom wing plates 2 and the web 1 is more stable, which greatly improves the torque resistance and load stability of the H-shaped steel in actual use.
