[0001] The utility model relates to the technical field of building construction, in particular to a connection node between a basement concrete column and a steel column. Background Art
[0002] With the development of society, there are more and more building projects. In building construction, steel columns and concrete columns are usually used. The building form with concrete columns at the lower part and steel structures at the upper part has also been widely applied. Especially during the construction of the basement, it is necessary to connect the steel column with the basement concrete column. Since the cross-section of the existing steel column is smaller than that of the concrete column, an outsourcing connection node is usually adopted, that is, the column foot of the steel column is buried in the top of the concrete column. When the cross-section of the column foot of the steel column is larger than that of the concrete column, the connection between the steel column and the concrete column will be offset, resulting in that the concrete column cannot completely wrap the column foot of the steel column, thereby reducing the construction quality and prolonging the construction period. Content of the Utility Model
[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that the construction quality of buildings is reduced due to the fact that the existing concrete column cannot completely wrap the column foot of the steel column.
[0004] For this purpose, the utility model provides a connection node between a basement concrete column and a steel column, including:
[0005] A basement top plate;
[0006] A concrete column, arranged below the basement top plate;
[0007] A connection assembly, arranged at the top end of the concrete column and connected with the basement top plate;
[0008] A steel column, arranged above the basement top plate and connected with the concrete column through the connection assembly.
[0009] Optionally, the cross-section of the column foot of the steel column is greater than or equal to the cross-section of the concrete column.
[0010] Optionally, concrete is arranged outside the steel column, and the concrete is suitable for wrapping the steel column.
[0011] Optionally, the connection assembly includes:
[0012] A connecting piece, arranged at the top end of the concrete column and connected with the steel bars in the basement top plate, and the connecting piece is suitable for connecting the concrete column and the steel column;
[0013] A fixing piece, sleeved outside the connecting piece, and the fixing piece is suitable for binding the connecting piece.
[0014] Optionally, the connecting member is made by bending steel bars, and the connecting member is U-shaped.
[0015] Optionally, the fixing member is set as stirrups.
[0016] Optionally, the width of the connecting member is the same as the width of the concrete wrapping the steel column.
[0017] The technical solution of the present utility model has the following advantages:
[0018] 1. The present utility model provides a connection node between a basement concrete column and a steel column, including a basement top plate, a concrete column, a connection assembly, and a steel column; the concrete column is arranged below the basement top plate; the connection assembly is arranged at the top end of the concrete column and is connected to the basement top plate; the steel column is arranged above the basement top plate and is connected to the concrete column through the connection assembly.
[0019] During the construction process of the basement, it is necessary to connect the steel column with the basement concrete column. Generally, the cross-section of the column foot of the steel column is smaller than that of the concrete column, and an outsourcing connection node is usually adopted, that is, the column foot of the steel column is buried in the top of the concrete column. When the cross-section of the column foot of the steel column is larger than that of the concrete column, it will cause the connection between the steel column and the concrete column to be offset, resulting in the concrete column being unable to completely wrap the column foot of the steel column, thereby reducing the construction quality and prolonging the construction period. In the embodiment of the present utility model, by arranging the connection assembly on the concrete column, the concrete column and the steel column can be accurately connected, and there will no longer be offset, so that the connection assembly wraps the column foot of the steel column, ensuring the construction quality, shortening the construction period, and saving the construction cost.
[0020] 2. The present utility model provides a connection node between a basement concrete column and a steel column. By setting the width of the connecting member to be the same as the width of the concrete wrapping the steel column, that is to say, the width of the connecting member is greater than the width of the column foot of the steel column, and thus the column foot of the steel column can be wrapped by the connection assembly to connect the concrete column and the steel column, solving the problem that the existing concrete column cannot wrap the column foot of the steel column.

[0030] Embodiment
[0031] As Figure 1As shown in the figure, this embodiment provides a connection node between a basement concrete column and a steel column, including a basement top plate 1, a concrete column 2, a connection component 3, and a steel column 4; the concrete column 2 is arranged below the basement top plate 1; the connection component 3 is arranged at the top end of the concrete column 2 and is connected to the basement top plate 1; the steel column 4 is arranged above the basement top plate 1 and is connected to the concrete column 2 through the connection component 3.
[0032] In the embodiment of the present utility model, first, the steel bars of the concrete column 2 are tied until they abut against the basement top plate 1. At the same time, the construction of the connection component 3 is carried out. Then, the steel column 4 is installed on the connection component 3. Then, the formwork of the concrete column 2 is closed and concrete is poured to complete the connection between the concrete column and the steel column.
[0033] During the construction of the basement, it is necessary to connect the steel column with the basement concrete column. Generally, the cross-section of the steel column base is smaller than that of the concrete column, and an external wrapping type connection node is usually adopted, that is, the base of the steel column is buried in the top of the concrete column. When the cross-section of the steel column base is larger than that of the concrete column, it will cause the connection between the steel column and the concrete column to be offset, resulting in the inability of the concrete column to completely wrap the base of the steel column, thereby reducing the construction quality and prolonging the construction period. In the embodiment of the present utility model, by arranging the connection component 3 on the concrete column 2, the concrete column 2 can be accurately connected to the steel column 4, and there will no longer be an offset. Furthermore, the connection component 3 wraps the steel column 4, ensuring the construction quality, shortening the construction period, and saving the construction cost.
[0034] Furthermore, the cross-section of the base of the steel column 4 is greater than or equal to the cross-section of the concrete column 2. Since the cross-section of the base of the steel column 4 is greater than or equal to the cross-section of the concrete column 2, the concrete column 2 cannot wrap the steel column 4. By arranging the connection component 3 at the top of the concrete column 2, the connection component 3 can wrap the base of the steel column 4, thereby completing the connection between the concrete column 2 and the steel column 4.
[0035] Furthermore, there is concrete 5 outside the steel column 4, and the concrete 5 is suitable for wrapping the steel column 4. By arranging the concrete 5 outside the steel column 4, the structural strength of the building can be enhanced, and the service life of the building can be prolonged.
[0036] In the embodiment of the present utility model, a plurality of column bars are arranged in the concrete column 2. Through the mutual connection between the plurality of column bars and then concrete pouring, the concrete column 2 is formed.
[0037] Furthermore, the connection assembly 3 includes a connecting member 31 and a fixing member 32. The connecting member 31 is disposed at the top end of the concrete column 2 and is connected to the steel bars in the basement roof slab 1. The connecting member 31 is adapted to connect the concrete column 2 and the steel column 4. The fixing member 32 is sleeved outside the connecting member 31, and the fixing member 32 is adapted to bind the connecting member 31.
[0038] Furthermore, the connecting member 31 is made by bending a steel bar, and the connecting member 31 is in a U shape. That is to say, the connecting member 31 is arranged as a U-shaped steel bar. In the embodiment of the present invention, the U-shaped steel bar is welded to the steel bars in the concrete column 2. Of course, the U-shaped steel bar can also be made by extending and bending the column bars in the concrete column 2, that is, the U-shaped steel bar and the steel bars in the concrete column 2 are integral. The embodiment of the present invention does not limit the setting form of the U-shaped steel bar, and those skilled in the art can change the setting form of the U-shaped steel bar according to the actual situation as long as the same technical effect can be achieved.
[0039] Furthermore, the fixing member 32 is arranged as a stirrup to fix the U-shaped steel bar through the stirrup. Of course, the fixing member 32 can also be arranged as a steel hook. The embodiment of the present invention does not limit the setting form of the fixing member 32, and those skilled in the art can change the setting form of the fixing member 32 according to the actual situation as long as the same technical effect can be achieved.
[0040] Furthermore, the width of the connecting member 31 is the same as the width of the concrete wrapping the steel column 4. In the embodiment of the present invention, by setting the width of the connecting member 31 to be the same as the width of the concrete wrapping the steel column 4, that is to say, the width of the connecting member is greater than the width of the steel column base, so that the column base of the steel column can be wrapped by the connection assembly to connect the concrete column and the steel column, and the problem that the existing concrete column cannot wrap the steel column is solved.
[0041] In the embodiment of the present invention, by wrapping the steel column 4 in the connecting member 31, the steel column 4 can rotate relative to the concrete column 2, so that the construction adjustment of the steel column 4 is more convenient, and the applicability of the connection node is improved.
[0042] The specific construction process of the connection node between the basement concrete column and the steel column provided by the present invention is as follows:
[0043] First, tie the column bars of the concrete column 2 and extend the column bars into the basement top slab 1. At the same time, construct the connecting member 31. After the construction of the connecting member 31 is completed, then construct the fixing member 32. Then, formwork the concrete column 2 and pour concrete. Next, install the steel column 4 on the connecting member 31. Finally, wrap the concrete 5 around the steel column 4 to complete the connection between the concrete column 2 and the steel column 4.
[0044] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
