Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] When building buildings, in order to improve the safety performance of buildings, steel concrete structures are often used, that is, structures formed by embedding steel inside reinforced concrete. The types of steel include H-shaped steel and the like. Embodiment 1 of the present invention provides a kind of ribbed H-shaped steel for this reason, see Figure 1-Figure 2 , which includes: a web 1 , an upper flange 21 , a lower flange 22 , an upper rib 31 and a lower rib 32 .

[0023] Specifically, the upper flange 21 and the lower flange 22 are arranged parallel to each other, the web 1 is located between the upper flange 21 and the lower flange 22, and is connected to the upper flange 21 and the lower flange 22 respectively, so ...

Abstract

The invention discloses H-shaped steel with a rib and a concrete structure of the H-shaped steel with the rib. The H-shaped steel with the rib comprises a web, a top flange and a bottom flange, wherein the web is located between the top and bottom flanges and is respectively connected with the top and bottom flanges. The H-shaped steel with the rib further comprises an upper rib formed in an upper included angle formed by connecting the web and the top flange and a lower rib formed in a lower included angle formed by connecting the web and the lower flange. The upper and lower ribs are integrally formed with the web, the top and bottom flanges through hot rolling. The concrete structure of the H-shaped steel with the rib comprises a reinforcing steel bar, concrete and the H-shaped steel with the rib. The reinforcing steel bar is arranged around the H-shaped steel with the rib, the concrete is poured between the H-shaped steel with the rib and the reinforcing steel bar, and the H-shaped steel with the rib is the above H-shaped steel with the rib. Through the technical scheme disclosed by the invention, the bonding compactness of the H-shaped steel with the rib and the concrete can be improved.

Description

technical field [0001] The invention relates to the fields of metal material engineering and construction, in particular to a ribbed H-shaped steel and a ribbed H-shaped steel concrete structure. Background technique [0002] The steel concrete structure is a structure formed by embedding section steel or welded steel components inside reinforced concrete. The types of steel are H-section steel, I-beam, angle steel, channel steel, etc. This structure can greatly improve the bearing capacity of components. In addition, it has good ductility, which can improve the seismic performance of components, especially suitable for high-rise buildings, subway platforms, underground passages and other places with high seismic requirements. Compared with the steel structure, the steel concrete structure also has the advantages of good fire resistance, good local and overall structural stability, and saving steel. [0003] However, since concrete is a heterogeneous material, when H-shaped...
