Technical Field

[0001] The utility model belongs to the technical field of building nodes, and in particular relates to a conversion node for giant steel pipe oblique column-shaped steel beam. Background Art

[0002] With the continuous improvement of architectural aesthetics, the functions and appearance of high-rise buildings are constantly developing in a diversified and personalized direction, and the application of oblique column conversion structures is becoming more and more extensive. The oblique column conversion structure node is a spatial structure composed of oblique column components on the outer surface of the building that cross in multiple directions and are arranged regularly. It can be set in a novel shape and has great overall lateral stiffness, which can bring better space for the functional layout of the building and is suitable for super high-rise buildings.

[0003] In order to enhance the overall appearance of the building, some buildings will use steel tube inclined columns and steel beams as inclined column conversion nodes. However, the conversion nodes of existing steel tube inclined columns and steel beams are complicated to construct and require formwork for node connection, which not only occupies the area and space of the building, but also affects the overall appearance of the building and fails to achieve the expected design effect. In particular, the conversion nodes using giant steel tube inclined columns and steel beams are large in size and weight, require a large amount of formwork support, have a long construction period, and have a large number of connectors and connection areas, which seriously affect the appearance of the building and reduce the aesthetics. Utility Model Content

[0007] As a further improvement of the technical solution, the hollow-web inclined column also includes an opening for easy connection; the opening is provided on the side of one end of the hollow-web inclined column connected to the steel beam.

[0008] As a further improvement of the technical solution, the hollow inclined column also includes a connecting plate; the connecting plate is welded to the opening.

[0009] As a further improvement of the technical solution, an end of the prefabricated steel plate away from the steel beam is provided with an inclination angle corresponding to the hollow inclined column.

[0025] Embodiment 1:

[0026] like Figures 1 to 3As shown, a conversion node for giant steel tube inclined column-section steel beam comprises a hollow inclined column 1, a section steel beam 2 and a prefabricated steel plate 3; the hollow inclined column 1 is a box-type inclined column, i.e., a giant steel tube inclined column; the section steel beam 2 is arranged horizontally, a connection port 21 is opened in the middle of the section steel beam 2, the connection port 21 faces upward, the size of the connection port 12 is smaller than the port size of the section steel beam 2, the connection port 12 corresponds to the port of the hollow inclined column 1, and is a rectangular structure, and the connection port 12 can be opened in advance before connection; the prefabricated steel plate 3 is provided in advance. One end of the prefabricated steel plate 3 extends into the interior of the steel beam 2 through the connecting port 21 and is welded and fixed to the steel beam 2, and the other end is exposed outside the steel beam 2; one end of the hollow inclined column 1 covers the exposed end of the prefabricated steel plate 3, and the inner wall is welded to the prefabricated steel plate 3, and the hollow inclined column 1 is located above the steel beam 2; preferably, the end of the prefabricated steel plate 3 away from the steel beam 2 is set with an inclination angle corresponding to the inclination of the hollow inclined column 1, so as to facilitate the welding of the prefabricated steel plate 3 and the hollow inclined column 1 and enhance the connection force.

[0027] Working method:

[0028] Before the hollow inclined column 1 is connected to the steel beam 2, a connection port 21 is first opened in the middle of the steel beam 2, and then one end of the prefabricated steel plate 3 is extended into the steel beam 2 through the connection port 21 and welded to the inner wall of the steel beam 2. After the prefabricated steel plate 3 is welded and fixed, the hollow inclined column 1 is hoisted by a lifting equipment so that the end of the hollow inclined column 1 is close to the connection port 21, and the end cover of the hollow inclined column 1 covers the exposed end of the prefabricated steel plate 3, and then the end of the prefabricated steel plate 3 away from the steel beam 2 is welded and fixed to the hollow inclined column 1 to form a conversion node. The structure is simple and the construction difficulty is small. No external formwork is required and the space occupied is small. At the same time, the prefabricated steel plate 3 is arranged inside the hollow inclined column 1 and the steel beam 2 to hide the supporting connection point inside, which effectively enhances the appearance.

[0029] like Figures 1 to 3 As shown, preferably, the orientation of the prefabricated steel plates 3 is perpendicular to the orientation of the steel beam 2 , the prefabricated steel plates 3 are located on both sides and the middle of the connection port 21 , and the prefabricated steel plates 3 are evenly spaced.

[0030] like Figure 4 As shown, preferably, the hollow inclined column 1 also includes a built-in steel plate 13; the built-in steel plate 13 is fixedly arranged inside the hollow inclined column 1 at intervals along the path of the hollow inclined column 1, and by arranging the built-in steel plate 13, the built-in steel plate 13 is an H-shaped steel and a cross-shaped steel, so as to improve the rigidity and bearing capacity of the hollow inclined column 1.

[0031] Embodiment 2:

[0032] like Figure 2 and Figure 4As shown, compared with Example 1, the difference is that the hollow inclined column 1 also includes an opening 11 that is convenient for connecting the hollow inclined column 1 with the prefabricated steel plate 3; an opening 11 is provided on the side of the end where the hollow inclined column 1 is connected to the steel beam 2, and the opening 11 is connected to the interior of the hollow inclined column 1, so that the situation inside the hollow inclined column 1 can be observed through the opening 11, and the interior of the hollow inclined column 1 can be extended through the opening 11. Preferably, openings 11 are provided on all four sides of the hollow inclined column 1; the hollow inclined column 1 and the steel beam 2 are connected through the prefabricated steel plate 3. When the end cover of the hollow inclined column 1 covers the end of the prefabricated steel plate 3 away from the steel beam 2, there is insufficient space and light, and it is difficult to weld the hollow inclined column 1 and the prefabricated steel plate 3. Therefore, by providing an opening 11 at the end where the hollow inclined column 1 is connected to the steel beam 2, the operating space is expanded and the light is increased, so as to reduce the difficulty of welding and facilitate welding of the hollow inclined column 1 and the prefabricated steel plate 3.

[0033] like Figure 2 As shown, preferably, the hollow inclined column 1 also includes a connecting plate 12; the connecting plate 12 is welded to the opening 11; after the prefabricated steel plate 3 and the hollow inclined column 1 are welded, the connecting plate 12 is welded to the opening 11 to seal the opening 11, thereby preventing flying insects and foreign objects from entering the hollow inclined column 1, reducing the internal loss of the hollow inclined column 1 and the prefabricated steel plate 3, and at the same time improving the integrity of the hollow inclined column 1 to ensure the overall appearance.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
