In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, integrally connected; can be mechanical connection and electrical connection; may be directly connected, indirectly connected through intervening agents, or may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood to be specific to those skilled in the art.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the combined steel structure includes a steel section 1, the steel section 1 is a steel structure with cavities inside, such as i-beam, H-beam, and channel beam, the cavity of the i-beam or H-beam is an area enclosed between two flanges and a web, and the cavity of the channel beam is an internal groove formed by two legs and a waist.

A plurality of groups of parallel reinforcing rib plates 2 are arranged in a cavity of the steel section bar 1, two ends of each reinforcing rib plate 2 are fixedly connected with the inner walls of two flanges or the inner walls of two legs of the steel section bar 1 respectively, the reinforcing rib plates 2 can be completed by welding or bolt connection or mortise and tenon mutual embedding, and the reinforcing rib plates 2 and the steel section bar can also be manufactured into an integrated structure when a steel structure is machined. The reinforcing rib plate 2 can reinforce the firmness among all parts of the steel structure, thereby increasing the strength, the rigidity and the overall safety.

In order to further improve the stability, rigidity and compression resistance of the structure, fold line steel bars 3 are arranged in the area between every two adjacent reinforcing rib plates 2, the fold line steel bars 3 are formed in a bending line shape by sequentially connecting more than three groups of steel bars, wherein one ends of the steel bars at the head and tail ends are fixedly connected with the reinforcing rib plates 2, the other ends of the steel bars at the head and tail ends are fixedly connected with the inner walls of the flanges or the inner walls of the legs of the steel section bar 1, and the two ends of the steel bar at the middle part are fixedly connected with the two adjacent reinforcing. The broken line steel bars 3, the reinforcing rib plates 2 and the inner walls of the steel sections 1 can be welded, connected by bolts or embedded in mortise and tenon joints, and the reinforcing rib plates 2 and the steel sections can be manufactured into an integrated structure during processing.

In order to make the connection between the reinforcing rib plate 2 and the steel section bar 1 more stable, the connection between the reinforcing rib plate 2 and the inner wall of the two flanges or the inner wall of the two legs of the steel section bar 1 is a round chamfer, i.e. the inner arcs are connected, so that the contact area between the two is larger, and the combination of the two is more stable.

In order to improve the whole bearing capacity, the thickness of the reinforcing rib plate 2 is not less than the thickness of the flange or the leg of the steel section bar 1.

In order to reduce the overall weight, the reinforcing rib plates 2 are hollow square tubes or circular tubes, and the broken line steel bars 3 are hollow circular tubes.

The foregoing merely illustrates preferred embodiments of the present invention, which are described in considerable detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, modifications and substitutions can be made, which are all within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
