Description

Technical Field

[0001] The utility model relates to a connection node structure of an angle steel column and an external wall, belonging to the technical field of building construction. Background Art

[0002] When constructing a steel structure factory building, steel columns need to be installed as building columns. In order to ensure the stability of the steel columns, the steel columns need to be fixedly connected to the structural columns to ensure the stability of the fixed connection.

[0003] The prior art for fixing the steel column is shown in China Publication No. CN210264078U, in which the steel column is fixed with pre-embedded bolts. When the exterior wall constructed of phosphogypsum bricks is covered with structural columns and pre-embedded bolts cannot be installed, there is a problem that the steel column cannot be fixedly connected to the structural column by the pre-embedded bolts. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a connection node structure between an angle steel column and an exterior wall.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a connection node structure of an angle steel column and an external wall, comprising:

[0007] Structural columns and steel columns, the steel columns are fixedly connected to the structural columns through steel bars C.

[0008] The two vertical sides of the structural column are provided with an outer wall A and an outer wall B, and the outer wall A and the outer wall B are located at the corner of the structural column.

[0009] The structural columns are made of reinforced concrete. The exterior walls A and B are made of phosphogypsum bricks.

[0010] The structural column has steel bars A extending into the outer wall A; the structural column has steel bars B extending into the outer wall A.

[0011] The ends of the steel bars A and B in the structural column have a crossing portion.

[0012] The steel bar C is inside the structural column, and both ends of the steel bar C extend to the exterior wall A and the exterior wall B respectively. The steel bar C in the exterior wall A has a first bending section that exposes the exterior wall A, and the steel bar C in the exterior wall B has a second bending section that exposes the exterior wall B.

[0013] The steel bar C has an intersection with the steel bars A and B.

[0014] The outer wall A and the outer wall B located at the corners of the structural column are installed with steel columns, which are fixed to the second bending section. The steel columns are welded and fixed to the first bending section through a connecting plate.

[0015] The beneficial effect of the utility model is that when the steel column is subjected to unstable load, the load is transmitted to the outer wall A and the outer wall B through the first bending section and the second bending section of the steel bar C. At the same time, the load on the steel column is transmitted to the structural column through the steel bar C and the steel bar A and the steel bar B, thereby achieving a fixed connection between the steel column and the structural column through the steel bar C, and solving the problem that the steel column cannot be fixedly connected to the structural column through embedded bolts.

[0018] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0019] like Figure 1 shown.

[0020] The present invention provides a connection node structure between a corner steel column and an exterior wall, comprising:

[0021] The structural column 1 is constructed by pouring reinforced concrete for solidification, and the two vertical sides of the structural column 1 are constructed by phosphogypsum bricks to form the external walls A2 and B3. The external walls A2 and B3 are located at the corners of the structural column 1.

[0022] The structural column 1 has a steel bar A21 extending into the outer wall A2; the structural column 1 has a steel bar B31 extending into the outer wall A2, and the ends of the steel bars A21 and B31 in the structural column 1 have a crossing portion.

[0023] The structural column 1 contains a steel bar C4, which intersects with the steel bars A21 and B31. Both ends of the steel bar C4 extend to the exterior walls A2 and B3 respectively. The steel bar C4 in the exterior wall A2 has a first bending section 41 that exposes the exterior wall A2, and the steel bar C4 in the exterior wall B3 has a second bending section 42 that exposes the exterior wall B3.

[0024] The outer wall A2 and the outer wall B3 located at the corner of the structural column 1 are contacted and installed with a steel column 5 , which is welded and fixed to the second bending section 42 , and the steel column 5 is welded and fixed to the first bending section 41 via a connecting plate 51 .

[0025] When the steel column 5 is subjected to load and becomes unstable, the steel column 5 is transmitted to the exterior wall A2 and the exterior wall B3 through the first bending section 41 and the second bending section 42 of the steel bar C4. At the same time, the load on the steel column 5 is transmitted to the structural column 1 through the steel bar C4 and the steel bars A21 and B31, thereby achieving a fixed connection between the steel column 5 and the structural column 1 through the steel bar C4, thereby solving the problem that the steel column cannot be fixedly connected to the structural column through embedded bolts.
