Description

Technical Field

[0001] The invention relates to the technical field of building profiles, in particular to an H-shaped steel with a corrugated wing plate and a corrugated web plate. Background Art

[0002] At present, similar steel structural components that can be used in technical fields such as construction projects, road bridges and culverts, bridge and tunnel linings, underground shafts, etc. include hot-rolled I-beams, hot-rolled H-beams, hot-rolled square steel pipes, welded box girders and corrugated web H-beams.

[0003] Among them, hot-rolled I-beams, hot-rolled H-shaped steels, hot-rolled square steel tubes, welded H-shaped steels, etc. use straight steel plates as flat flanges and flat webs, and the stability of the flat steel plates themselves is poor, so their shear bearing capacity is low. Therefore, it is necessary to increase the thickness of the flanges and webs to obtain higher bearing capacity, but this results in excessive steel consumption in the flanges and webs, causing waste of steel.

[0004] Ordinary hot-rolled I-beams and H-beams are hot-rolled in factories. Due to the processing technology, their webs must be straight plates. Welded H-beams, on the other hand, are made by welding two flange plates and a flat web together to form an H-shaped section. When the hot-rolled steel specifications cannot meet the requirements, welded H-beams can be used, but welded H-beams mostly use two-sided fillet welds, which requires a lot of welding work. Similarly, ordinary hot-rolled I-beams and welded H-beams use a lot of steel, mainly because the flat web has a low buckling resistance, so the thickness of the web needs to be increased. The same problem exists in welded H-beams, so the height ratio of the web needs to be limited during design, resulting in a thicker web thickness, so the amount of steel used will increase.

[0005] Therefore, it is necessary to study a method to break through the limitation of the height-to-thickness ratio of the web of the traditional flat wing plate and flat web H-shaped steel and overcome the problem that the flat wing plate and flat web are prone to local instability and deformation. It is necessary to develop a new type of H-shaped steel with simple structure and reasonable force. Summary of the invention

[0006] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide an H-shaped steel with corrugated wing plates and corrugated webs, which has a simple structure, is easy to install, has high load-bearing capacity, high strength, and excellent force-bearing performance, can effectively absorb vibrations, has excellent anti-fatigue performance, is light in weight, and has a wider range of uses.

[0007] In order to solve the above problems, the present invention adopts the following technical solution: an H-shaped steel with corrugated wing plates and corrugated web plates, comprising an upper wing plate, a web plate and a lower wing plate, characterized in that:

[0008] The upper wing plate is continuously corrugated along the length direction, and the center plane of the upper wing plate is arranged parallel to the lower wing plate.

[0009] The lower wing plate is a flat plate.

[0010] The web is perpendicular to the upper wing plate and the lower wing plate, and the web is continuously corrugated along the length direction.

[0011] The waveform size of the upper wing plate and the web plate is the same, both are sine waves, the wave pitch of the waveform is between 68mm-500mm, and the height of the waveform is between 13mm-237mm.

[0012] Furthermore: the web is formed by welding with the upper wing plate and the lower wing plate respectively.

[0013] The beneficial effects of the present invention are:

[0014] 1. The web is continuously corrugated along the length direction. Compared with the traditional I-beam and H-beam, the shear resistance of the entire cross section is effective, breaking through the limitation of the height-to-thickness ratio of the traditional flat web H-beam, and overcoming the problem of local instability and deformation of the flat flange and flat web. It is a new type of efficient steel structure profile.

[0015] 2. The upper wing plate and the web plate have the same waveform size, both of which are sinusoidal. The two corrugated plates with the same waveform size are formed by welding. They have the characteristics of high load-bearing capacity, high strength, excellent force-bearing performance, excellent fatigue resistance and light weight. They are ideal structural steel materials. They can be used as a substitute for traditional I-beams and H-beams, and are more widely used than I-beams and H-beams.

[0016] 3. The upper wing plate is in a corrugated shape, which can reduce its thickness without reducing the strength of the upper wing plate. The web plate is made into a corrugated shape, which can increase the stability of the web plate, and keep the lower web plate in a flat shape, which is convenient for the connection and contact between the steel section and the structure to be reinforced. This structural form has increased stability and light weight, which is more convenient for use in engineering structures such as construction projects, road bridges and culverts, bridge and tunnel linings, underground shafts, etc. The upper wing plate and web plate structure of this structure makes the elastic deformation capacity and bending and stretching capacity of the steel section structure higher. The seismic effect of the corrugation is obvious, and it can well absorb the torsion and vibration of the structure during the stress process. It has high bearing capacity, high strength, excellent stress performance, excellent fatigue resistance and light weight. It is an ideal structural steel material. It can be used as a substitute for traditional I-beams and H-beams, and it is more widely used than I-beams and H-beams. BRIEF DESCRIPTION OF THE DRAWINGS
