[0003] The existing steel structure support is mainly used for dyeing columns on buildings, and its steel structure support mostly adopts an "I"-shaped structure, which consists of two upper and lower horizontal plates as the main reinforcement, and the middle vertical vertical plate is formed by the supporting web. The steel purlins of the structure have poor bending performance, so the steel purlins of this shape are easy to bend and deform during engineering use, and the purlin dyeing is easy to shift as a whole, resulting in the instability of the entire building
In the prior art, there are ribs in the notches on both sides of the "I" shaped purlin beam, and the setting of the ribs is perpendicular to the inner surface of the notch. The purlin ribs of this structure are set rigidly, and cannot Purlin beams to be adjusted

Embodiment 1
[0016] Such as figure 1 , figure 2 and image 3 As shown, a steel purlin of a steel structure includes an "I"-shaped main beam 1, which is composed of two upper and lower horizontal plates as the main reinforcement, and the middle longitudinal vertical plate is a supporting web. The body is provided with a number of reinforcing ribs 2 at intervals in turn, and the horizontal plates on both sides of the "I"-shaped main beam 1 are provided with a strip-shaped notch 3, and the strip-shaped notch 3 is provided with a strip-shaped groove The slide block 4 that slides through the mouth, the two reinforcing ribs 2 are fixedly connected with a slider 4, the purpose of this connection is that the reinforcing ribs 2 are arranged in the shape of "herringbone" in the notch on both sides of the main beam, and the reinforcing ribs 2 and The horizontal plates form several triangles, so the compressive and bending strength is enhanced. The outer sides of the horizontal plates on both sides...

The invention discloses a steel structure purlin. The purlin comprises an I-shaped girder, wherein a plurality of reinforcing ribs are sequentially formed in notches in two sides of the girder along a cylinder body at intervals; strip-shaped grooves are formed in transverse plates on two sides of the I-shaped girder, and slide blocks capable of sliding along the strip-shaped grooves are arranged in the strip-shaped grooves; every two reinforcing ribs are fixedly connected with one slide block; the reinforcing ribs are arranged in the notches in two sides of the girder in an inverted V shape; adjusting devices are arranged outside the transverse plates on two sides of the I-shaped girder, and are connected with the slide blocks. According to the steel structure purlin, the integral tensile and bending strength can be improved, and the strength required by different purlins can be realized by changing angles of the reinforcing ribs.
Description
technical field [0001] The invention relates to the technical field of steel structures, in particular to a steel purlin for a steel structure. Background technique [0002] Due to its strong toughness, light weight and high strength, steel is widely used in the field of construction, especially in shopping malls, stadiums and high-rise buildings with large spans. [0003] The existing steel structure support is mainly used for dyeing columns on buildings, and its steel structure support mostly adopts an "I"-shaped structure, which consists of two upper and lower horizontal plates as the main reinforcement, and the middle vertical vertical plate is formed by the supporting web. The steel purlins of the structure have poor bending performance, so the steel purlins of this shape are easy to bend and deform during engineering use, and the purlin dyeing is easy to shift as a whole, resulting in the instability of the entire building. In the prior art, there are ribs in the notc...
