Description

Technical Field

[0001] The utility model relates to the technical field of building structure design, in particular to a beam-column node structure. Background Art

[0002] As architectural forms become more and more complex, some special buildings, such as greenhouses, have higher requirements for building permeability. The facades of large-span spatial structure buildings can adopt an integrated design method of facade structure and curtain wall, and the facade structural components adopt small-section components corresponding to the curtain wall section modulus.

[0003] In some cases of integrated design of spatial structure and curtain wall, the architectural effect requires that the facade structural components cannot adopt the conventional larger cross-section form, but adopt a large number of small-section steel columns and small-section steel beams, and the cross-section is a long rectangular form. In order to correspond to the curtain wall section modulus, the facade structural components generally adopt a cross-section width of 60mm, 80mm and other sizes. Excluding the section wall thickness, the internal spacing is very small, making it impossible to weld internal partitions in conventional beams and columns, affecting the force performance of the beam-column node. Utility Model Content

[0004] The purpose of the utility model is to provide a beam-column node structure, which not only meets the architectural effect requirements of small-section beam-column nodes, but also achieves the force-bearing performance of conventional beam-column nodes, and solves the problem that cross partitions cannot be added in small-section beams and columns.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a beam-column node structure, including a box beam, a box column and a connecting plate, the box beam includes an outer flange plate and an inner flange plate that are relatively arranged, the outer flange plate intersects vertically with the outer side wall of the box column and is flush with each other, the inner flange plate is at a preset distance from the inner side wall of the box column, the connecting plate is partially fixed in the box column and at least one end extends out of the box column, and the end of the connecting plate extending out of the box column is fixedly connected to the inner flange plate.

[0006] Optionally, the inner flange plate is provided with a notch groove, one end of the connecting plate extending out of the box-type column covers the notch groove, and the outer surface of the connecting plate is flush with the outer surface of the inner flange plate.

[0007] Optionally, one end of the connecting plate extending out of the box-type column is welded to the inner flange plate.

[0008] Optionally, both ends of the connecting plate extend out of the box column and are respectively connected to the box beams on both sides of the box column.

[0009] Optionally, the portion of the connecting plate located inside the box-type column is designed to be thickened.

[0010] Optionally, the connecting plate is connected to the box-type column by welding.

[0011] Optionally, the outer flange plate is welded to the outer side wall of the box column.

[0012] Optionally, the box beam further includes two webs arranged opposite to each other, wherein the webs intersect the box column perpendicularly and are welded to each other.

[0013] Optionally, the connecting plate, the box beam and the box column are all made of steel.

[0014] Optionally, the cross-sections of the box beam and the box column are both rectangular.

[0015] The beam-column joint structure provided by the utility model has at least one of the following beneficial effects:

[0016] 1) By providing the connecting plate to connect the box beam and the box column, the architectural effect requirements of the small-section beam-column node are met, and the stress performance of the conventional beam-column node is achieved, solving the problem that a diaphragm cannot be added in a small-section beam-column;

[0017] 2) The connecting plate is directly welded to the box beam and the box column. Since the box beam mainly bears horizontal loads, the web of the box beam can only bear horizontal shear force. The beam-column node is subjected to the same force as the general beam-column connection under the action of external horizontal force, thus realizing the rigid connection of small-section beams and columns.

[0018] 3) The connection plate and the box-shaped column can be slotted and welded in the factory, and only the connection plate and the box-shaped beam need to be welded on site, which simplifies the on-site operation;

[0019] 4) The beam-column node structure provided by the utility model has high installation accuracy, good building effect, and reasonable and reliable force transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Please refer to Figure 1-Figure 4 The present embodiment provides a beam-column node structure, including a box beam 10, a box column 20 and a connecting plate 30, wherein the box beam 10 includes an outer flange plate 11 and an inner flange plate 12 which are arranged opposite to each other, wherein the outer flange plate 11 intersects perpendicularly with the outer side wall of the box column 20 and is flush with each other, and the inner flange plate 12 is at a preset distance from the inner side wall of the box column 20, wherein the connecting plate 30 is partially fixed in the box column 20 and at least one end extends out of the box column 20, and the end of the connecting plate 30 extending out of the box column 20 is fixedly connected to the inner flange plate 12.

[0030] By providing the connecting plate 30 to connect the box beam 10 and the box column 20, the architectural effect requirements of the small-section beam-column node are met, and the force performance of the conventional beam-column node is achieved, solving the problem that a transverse partition cannot be added in a small-section beam-column.

[0031] In this embodiment, the box column 20 is vertically arranged, and its cross section is rectangular, and the cross-sectional width of the box column 20 is not greater than 80 mm, and its material is a steel member. The box beam 10 is horizontally arranged, and its cross section is also rectangular, and the cross-sectional width of the box beam 10 is not greater than 80 mm, and its material is also a steel member.

[0032] In this embodiment, the box beam 10 includes a web plate 13 arranged opposite to each other up and down, and an outer flange plate 11 and an inner flange plate 12 arranged opposite to each other inside and outside. The outer flange plate 11 intersects vertically with the outer side wall of the box column 20 and is flush with each other. The width between the outer flange plate 11 and the inner flange plate 12 is smaller than the width between the inner and outer side walls of the box column 20, so that the inner flange plate 12 has a preset distance from the inner side wall of the box column 20. It can also be understood that the box beam 10 is eccentrically arranged relative to the box column 20.

[0033] Preferably, the inner flange plate 12 is provided with a notch, and one end of the connecting plate 30 extending out of the box column 20 covers the notch, and the outer surface of the connecting plate 30 is flush with the outer surface of the inner flange plate 12, which is equivalent to cutting off part of the inner flange plate 12 of the box beam 10, and then using the part of the connecting plate 30 extending out of the box column 20 to just replace the cut-off part of the inner flange plate 12, so that from the outside it looks like the connecting plate 30 and the box beam 10 are integrally formed, and the aesthetics are better. At the same time, the part of the connecting plate 30 located in the box column 20 is equivalent to a diaphragm to improve the force performance of the beam-column node.

[0034] In this embodiment, one end of the connecting plate 30 extending from the box column 20 is welded to the inner flange plate 12, and the connecting plate 30 is welded to the box column 20. During specific processing, the size of the connecting plate 30 can be pre-designed, and the part to be replaced can be pre-cut off on the inner flange plate 12 of the box beam 10, and then the box column 20 can be grooved in the factory, and the connecting plate 30 and the box column 20 can be welded, so that only one end of the connecting plate 30 extending from the box column 20 and the inner flange plate 12 of the box beam 10 need to be welded at the construction site, thereby simplifying the on-site operation.

[0035] In this embodiment, both ends of the connecting plate 30 extend out of the box column 20 and are respectively connected to the box beams 10 on both sides of the box column 20. Of course, in the case where the box beam 10 is arranged on only one side of the box column 20, it is only necessary to insert one end of the connecting plate 30 into the box column 20 and connect the other end to the box beam 10, and the present invention does not impose any limitation on this.

[0036] Preferably, Figure 4 As shown, the portion of the connecting plate 30 located inside the box column 20 is thickened to further increase the connection strength of the beam-column node and further improve the force-bearing performance of the beam-column node. In this embodiment, the end of the connecting plate 30 extending out of the box column 20 is directly designed to be the same thickness as the inner flange plate 12 of the box beam 10 to ensure that the outer surface of the connecting plate 30 is flush with the outer surface of the inner flange plate 12.

[0037] In this embodiment, the connecting plate 30 is a steel plate.

[0038] In this embodiment, the outer flange plate 11 is connected to the outer side wall of the box column 20 by welding.

[0039] In this embodiment, the box beam 10 further includes two webs 13 that are arranged opposite to each other. The webs 13 are perpendicularly intersected with the box columns 20 and are welded together. The webs 13 mainly bear horizontal shear force.

[0040] In summary, the embodiment of the utility model provides a beam-column node structure, which connects the box beam 10 and the box column 20 by setting the connecting plate 30, thereby meeting the architectural effect requirements of the small-section beam-column node, and also achieving the force-bearing performance of the conventional beam-column node, thereby solving the problem that it is impossible to add a cross-partition in the small-section beam-column.

[0041] In addition, it should be recognized that although the present invention has been disclosed as a preferred embodiment, the above embodiment is not intended to limit the present invention. For any technician familiar with the art, without departing from the scope of the technical solution of the present invention, the above disclosed technical content can be used to make many possible changes and modifications to the technical solution of the present invention, or modified into equivalent embodiments of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of protection of the technical solution of the present invention.
