Background

The main bearing structure of the roof is a multi-section H-shaped steel beam supported by more than two steel columns (supporting columns determined according to the building scheme), and the steel beams are connected with each other by splicing flange plates welded on the end surfaces of the steel beams and high-strength bolts penetrating through the flange plates to form a steel frame system capable of bearing the gravity load, the horizontal wind load and the earthquake action of the roof, as shown in figure 1.

As one method of designing a steel structure with reduced weight, considering that the web of the H-beam described above requires a relatively large thickness for technical reasons (occurrence of local buckling instability) and therefore consumes a large amount of material, in the prior art, the web of the H-beam is replaced with a corrugated web capable of effectively suppressing buckling instability, and as shown in fig. 2, the thickness of the corrugated web can be reduced by 50% as compared with the standard H-beam web, so that the consumption of material can be greatly reduced.

The corrugated web H-shaped steel is used as a roof steel frame beam, the joints are still connected by the splicing flange plates and the high-strength bolts penetrating through the splicing flange plates, and the web material is very thin, so that the connection strength of the steel beam and the splicing flange plates is insufficient, and the steel beam and the splicing flange plates cannot pass through design checking calculation. Therefore, as shown in fig. 3, the existing method is to weld a steel plate 4 with a larger thickness (meeting the verification in the technical standard) after cutting off the web in the form of corrugations at the position of the splicing node. However, this method involves many steps such as web cutting and butt-jointing of a thin plate and a thick plate, and is inefficient in operation, poor in quality assurance, and liable to cause a safety hazard after construction.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 4 to 6, the present embodiment provides a corrugated web H-shaped steel beam connection node structure, which includes a splicing flange plate 2 and a corrugated web H-shaped steel beam 1. The splicing flange plate 2 is connected with two ends of the H-shaped steel beam 1 with the corrugated web plate.

The corrugated web H-section steel beam 1 comprises an upper plate 11, a lower plate 12, a corrugated web 13 and a reinforcing plate 14. The centers of the upper plate 11 and the lower plate 12 are respectively connected with the upper side and the lower side of the corrugated web 13, and the reinforcing plates 14 are parallelly attached and welded on the two side surfaces of the corrugated web 13. The reinforcing plate 14 is used for sealing a plurality of wave-shaped grooves 15 at the end of the connecting and splicing flange plate 2 of the corrugated web 13, the upper end and the lower end of the reinforcing plate 14 are respectively welded with the upper plate 11 and the lower plate 12, and one side edge of the reinforcing plate is welded with the splicing flange plate 2. Original corrugated web 13 and reinforcing plate 14 have constituted confined box structure, are connected the back with concatenation flange board 2, and the intensity and the stability of hookup location obtain abundant assurance.

The reinforcing plate 14 is made of the same material as the H-shaped steel beam, generally Q355; the thickness is generally 6-10 cm, and 6cm is adopted in the embodiment. In this example, the corrugated web 13 is a trapezoidal corrugated plate, and is provided with trapezoidal corrugated grooves 15 with staggered directions, the reinforcing plates 14 are of a sectional structure, each section of the reinforcing plate 14 encloses one trapezoidal corrugated groove 15, and the reinforcing plates 14 and the corrugated web 13 are connected by fillet welding.

This connected node structure still is equipped with right angle set square 3, and a right angle limit welding concatenation flange board 2 of this right angle set square 3, another direct limit welding upper plate 11 or hypoplastron 12 for further strengthen connection performance.

The principle of the embodiment is as follows:

considering that the existing machining method of the corrugated web H-shaped steel beam connecting node structure is complex, most of corrugated web beams need to be machined after finished products are purchased from suppliers, and the original beam section needs to be damaged and then strengthened. And the welding seam has higher requirement in the reinforcing process, and the quality is difficult to control. Adopt the utility model discloses paste and weld reinforcing plate 14's mode, close corrugated web 13 near the wave groove 15 of node and seal and form closed box structure to improve the holistic rigidity of web, satisfy the prerequisite of calculation formula is tested to the node among the technical standard.
