Description

Technical Field

[0001] The invention relates to an integral connection structure in which multiple steel beams are gathered together, belonging to the technical field of engineering steel structures. Background Art

[0002] In the design of steel structure workshops, the connection between steel beams is generally a flat connection or a lap connection between the secondary beams and the main beams. However, in some cases, due to equipment configuration, multiple steel beams converge at one point and the steel beams cannot form a straight line. At this time, the connection between the steel beams needs to be made into a rigid connection (welding or bolt connection) to ensure that the multiple steel beams are stressed as a whole. However, what kind of connection structure should be used for such eccentrically distributed multiple steel beams to ensure that the multiple steel beams are stressed as a whole has always been a technical problem that needs to be solved in the industry. Summary of the invention

[0003] The object of the present invention is to provide an integral connection structure for bringing together multiple steel beams, which enables each steel beam to be rigidly connected to a node, thereby meeting the overall force requirements.

[0004] The technical solution of the present invention is an integral connection structure in which multiple steel beams are gathered together, wherein a steel pipe is vertically arranged at the intersection area of ​​the center lines of multiple unequally distributed steel beams, the steel pipe is filled with concrete, and multiple connecting webs and multiple stiffening plates are fixed on the outer wall of the steel pipe, and a connecting web and a stiffening plate are correspondingly arranged on the center line of each steel beam, and the connecting web and the stiffening plate are symmetrically arranged on both sides of the steel pipe, and a special-shaped steel plate is fixedly connected to the top and bottom of the steel pipe respectively, and the multiple connecting webs and two special-shaped steel plates are rigidly connected to the multiple steel beams respectively.

[0005] In the aforementioned integral connection structure where multiple steel beams are gathered together, two special-shaped steel plates are respectively at the same height as the top and bottom surfaces of the steel beams, and the special-shaped steel plates are welded and fixed to the top and bottom plates of the steel beams; the connecting web is rigidly connected to the web of the steel beam via the connecting steel plate.

[0006] In the aforementioned integral connection structure in which multiple steel beams are gathered together, a connection steel plate is provided on each side of the connection web, and the two connection steel plates are connected to the connection web and the web of the steel beam by welding or bolts.

[0007] In the aforementioned integral connection structure in which multiple steel beams are gathered together, the far end of the stiffening plate extends to the edge of the special-shaped steel plate.

[0008] Beneficial effects of the invention: Compared with the prior art, the invention provides a steel pipe at the junction of steel beams, and closes the special-shaped steel plates at the upper and lower ends of the steel pipe, and sets a connecting web and stiffening ribs for connecting the steel beams around the steel pipe, and then connects with other steel beams through the node structure, so as to achieve the effect of the steel beams being stressed as a whole. The device has a simple structure, is easy to use, and has good promotion and application value. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0012] An embodiment of the present invention: An integral connection structure in which multiple steel beams are gathered together, wherein a steel pipe 2 is vertically arranged at the intersection area of ​​the center lines of multiple unequally distributed steel beams 1, and multiple connecting webs 3 and multiple stiffening plates 4 are welded and fixed on the outer wall of the steel pipe 2, a connecting web 3 is correspondingly arranged on the center line of each steel beam 1, and a special-shaped steel plate 5 is fixedly connected to the top and bottom of the steel pipe 2, and the multiple connecting webs 3 and two special-shaped steel plates 5 are rigidly connected to the multiple steel beams 1 respectively.

[0013] by Figure 1 Taking the three steel beams 1 as an example, the three steel beams 1 form a Y-shaped distribution, and three connecting webs 3 and three stiffening plates 4 are welded and fixed on the steel pipe 2, one connecting web 3 is correspondingly connected to one steel beam 1, and the special-shaped steel plate 5 is also made into a Y-shaped structure, and each corner of the special-shaped steel plate 5 is fixedly connected to one steel beam 1.

[0014] The height of the two special-shaped steel plates 5 plus the steel pipe 2 is just equal to the height of the steel beam 1, so that the two special-shaped steel plates 5 are respectively at the same height as the top and bottom surfaces of the steel beam 1, which facilitates welding and fixing the edges of the two special-shaped steel plates 5 to the top and bottom plates of the steel beam 1. The connecting web 3 is rigidly connected to the web of the steel beam 1 through the connecting steel plate 6.

[0015] A connecting steel plate 6 is provided on each side of the connecting web 3. The two connecting steel plates 6 are connected to the connecting web 3 and the web of the steel beam 1 by welding or bolts. The two connecting steel plates 6 can improve the connection quality between the steel beam 1 and the connecting web 3 and ensure a firm connection.

[0016] The far end of the stiffening plate 4 extends to the edge of the special-shaped steel plate 5, so that the overall structure can achieve the best stress-bearing effect.

[0017] When the overall structure is subjected to a heavy load, the interior of the steel pipe 2 can be filled with concrete to prevent the steel pipe 2 from being deformed under the high load.

[0018] A connecting web 3 and a stiffening plate 4 are correspondingly arranged on the center line of each steel beam 1. The connecting web 3 and the stiffening plate 4 are symmetrically arranged on both sides of the steel pipe 2, so that the overall structure can achieve the best force effect.
