Description

Technical Field

[0001] This utility model patent belongs to the technical field of steel structures, and specifically relates to a device for connecting steel columns and steel beams. Background Art

[0002] When designing steel structures, considering factors such as connection methods, mechanical properties, and installation convenience, the cross-sections of steel beams and steel columns usually adopt H-shaped steel components. However, when designing the support structure of a photovoltaic corridor, factors such as mechanical properties, applicable component types, and appearance requirements need to be considered, and the cross-section of the steel column usually adopts a circular tube form. Generally, there are two connection methods for circular steel pipe columns and H-shaped steel beams: external welding with an outer ring plate type and through-welding of partition plates with circular pipe columns segmented. However, in order to improve the power generation efficiency of the photovoltaic corridor, the top components are usually designed with a certain inclination angle, which requires the H-shaped steel beams in the support structure system to be installed obliquely. These two connection methods are not suitable for the inclined connection of circular steel pipe columns and H-shaped steel beams. If the circular steel pipe column and the H-shaped steel beam are directly welded on-site, the welding quality is difficult to guarantee, the construction efficiency is low, and the construction risk coefficient is high. Therefore, a device for connecting steel columns and steel beams is needed. Summary of the Utility Model

Any embodiment or design solution described as "exemplary", "for example", or "for instance" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary", "for example", or "for instance" is intended to present the relevant concepts in a specific manner.

[0025] In the description of the embodiments of the present application, the term "and / or" is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, B exists alone, and A and B exist simultaneously. Additionally, unless otherwise specified, the term "plurality" means two or more.

[0026] In the description of the embodiments of the present application, the orientation or positional relationships indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, or the orientation or positional relationships in which the products of this application are customarily placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the technical features indicated. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] In the description of the embodiments of the present application, terms such as "horizontal", "vertical", "hanging", "perpendicular", etc. do not mean that the components are required to be absolutely horizontal or hanging, but may be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly inclined.

[0028] In addition, in the description of the embodiments of the present application, unless otherwise clearly specified and defined, the terms "set", "install", "connect", and "couple" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0029] There are two ways to connect a general circular steel pipe column and an H-shaped steel beam, namely the external welded outer ring plate type and the through-type welding partition plate of the segmented circular steel pipe column. However, in order to improve the power generation efficiency of the photovoltaic corridor, the top components are usually designed with a certain inclination angle, which requires the H-shaped steel beam in the support structure system to be installed obliquely. These two connection methods are not suitable for the inclined connection of the circular steel pipe column and the H-shaped steel beam. If the circular steel pipe column and the H-shaped steel beam are directly welded on site, the welding quality is difficult to guarantee, the construction efficiency is low, and the construction risk coefficient is high.

[0030] To solve the above technical problems, the present application proposes a device for connecting a steel column and a steel beam.

[0031] Figure 1 The perspective view of a device for connecting a steel column and a steel beam provided by an embodiment of the present application is shown. The device includes: an H-shaped steel component 1, a flange plate 2, and a rectangular steel plate 3; the top of the H-shaped steel component 1 is a cut surface with a preset inclination angle; the rectangular steel plate 3 is connected to the cut surface, and a plurality of openings are provided on the rectangular steel plate 3; the flange plate 2 is connected to the bottom of the H-shaped steel component 1, and a plurality of openings are provided on the flange plate 2. In a specific example, the steel column can be a circular steel pipe column 8, and the steel beam can be an H-shaped steel beam 5. In another specific example, the rectangular steel plate 3 and the cut surface can be connected by welding. The flange plate 2 and the bottom of the H-shaped steel component 1 can be connected by welding. In yet another example, the flange plate 2 and the steel column 8 can be connected by bolts, and the rectangular steel plate 3 and the steel beam 5 can be connected by bolts.

[0032] For example, the top of the H-shaped steel component 1 can be cut by a cutting machine into a cut surface with a consistent inclination angle, and then the prepared rectangular steel plate 3 is connected to the cut surface by welding. A plurality of openings are provided on the rectangular steel plate 3, as Figure 2 shown, the rectangular steel plate 3 is connected to the H-shaped steel beam 5 by bolts, the flange plate 2 is connected to the bottom of the H-shaped steel component 1 by welding, a plurality of openings are provided on the flange plate 2, a second flange plate 9 is welded on the top of the circular steel pipe column 8, and a stiffening plate 7 is provided at the connection corner to enhance the stress performance of the joint. The flange plate 2 and the circular steel pipe column 8 are connected by bolts.

[0033] In one embodiment, the device may further include an ear plate 4, the ear plate 4 is connected to the flange of the H-shaped steel component 1, and a plurality of openings are provided on the ear plate 4. As Figure 1 shown, the ear plate 4 can be welded to the flange of the H-shaped steel component 1, and a plurality of openings are provided on the ear plate 4. The ear plate 4 can be used to connect to the C-shaped connecting rod 6 by bolts. For example, as Figure 3 shown, the ear plate 4 and the C-shaped connecting rod 6 can be connected by bolts. In different examples, the number of ear plates 4 can be one or two. Specifically, for example, if it is the middle column of the photovoltaic corridor, ear plates 4 are welded to the flanges on both sides of the H-shaped steel component 1 in the device, while for the side column, only one side ear plate 4 needs to be welded, asFigure 4 as shown

[0034] With this device, the steel column and the steel beam can be conveniently connected. Thus, on-site welding operations are avoided, the installation convenience is improved, and the installation quality is ensured.

[0035] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention.
