The connection node structure comprises a constructional column formed by concrete; the embedded bolt is used for being fixedly connected with the steel column, and the embedded bolt is embedded in the constructional column; a first reinforcing steel bar fixed with the embedded bolt is mounted in the constructional column; a second steel bar used for extending into the wall body is installed in the constructional column. Transient concentrated large load of the steel column is transmitted into the constructional column through the embedded bolts and the first steel bars coiled in a roundabout mode, the constructional column pulls the wall body to be dispersed through the strength of the constructional column and the second steel bars, and it is guaranteed that the state of the steel column is stable after the steel column is fixedly connected; the problem that an embedded bolt embedded in a concrete component cannot disperse a large load to ensure the fixed connection stability of a steel column is solved.

Description

Technical Field

[0001] The utility model relates to a connection node structure between a steel column at a deformation joint and a wall body, belonging to the technical field of building construction. Background Art

[0002] When constructing a steel structure building, it is necessary to cast the structural columns first, and then install the steel columns on the structural columns formed by the concrete casting.

[0003] The prior art for achieving fixed connection between concrete components and steel columns is disclosed in Chinese Patent Publication No. CN106703014B, which discloses that the steel base is fixed by embedded bolts. Although the steel base can be fixedly connected with the embedded bolts, when a short-term concentrated large load appears on the steel column, the embedded bolts embedded in the concrete components cannot disperse the large load to ensure the stability of the fixed connection of the steel column. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a connection node structure between a steel column at a deformation joint position and a wall.

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

[0006] The utility model provides a connection node structure between a steel column and a wall at a deformation joint position, comprising:

[0007] Structural columns made of concrete;

[0008] Embedded bolts used for fixed connection with steel columns, the embedded bolts are embedded in the structural columns;

[0009] A first steel bar fixed with embedded bolts is installed inside the structural column;

[0010] A second steel bar extending into the wall is installed in the structural column.

[0011] The first steel bar is coiled in a circuitous manner inside the structural column.

[0012] The structural columns are distributed in two intervals, and there is a deformation joint between the two structural columns; the deformation joint is installed with a water stop strip for waterproof sealing filling.

[0013] A wall is constructed on the side of the structural column, and the second steel bar extends from the structural column into the wall.

[0014] The second steel bar intersects with the first steel bar in the structural column.

[0015] The embedded bolts are fixedly connected with the steel columns.

[0016] The beneficial effect of the utility model is that the short-term concentrated large load of the steel column is transferred to the structural column through the embedded bolts and the first steel bar that is coiled in a circuitous manner. The structural column uses its own strength and the second steel bar to pull the wall to disperse the load, thereby ensuring the stability of the steel column after the fixed connection. This solves the problem that the embedded bolts embedded in the concrete constituent components cannot disperse the large load to ensure the stability of the fixed connection of the steel column.

[0018] In the figure: 1-structural column; 11-deformation joint; 2-embedded bolt; 12-first steel bar; 3-wall; 31-second steel bar; 4-steel column. DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0020] like Figure 1 shown.

[0021] A connection node structure between a steel column and a wall at a deformation joint position of the present application comprises:

[0022] The structural column 1 is formed by pouring and curing concrete. The structural column 1 is distributed in two intervals. There is a deformation joint 11 between the two structural columns 1. The deformation joint 11 is constructed and installed with a water stop belt for waterproof sealing.

[0023] An embedded bolt 2 is embedded in the side of the structural column 1 , and a first steel bar 12 is installed inside the structural column 1 . The first steel bar 12 is welded and fixed to the embedded bolt 2 , and the first steel bar 12 is coiled inside the structural column 1 .

[0024] A wall 3 is constructed on the side of the structural column 1 , and a second steel bar 31 is installed in the structural column 1 and extends into the wall 3 . The second steel bar 31 and the first steel bar 12 intersect in the structural column 1 .

[0025] The embedded bolts 2 are screwed together or welded to the steel columns 4, and the steel columns 4 can be regarded as the cross beams of the steel structure workshop.

[0026] When the steel column 4 is subjected to a short-term concentrated large load, the steel column 4 transfers the load to the structural column 1 through the embedded bolts 2 and the first steel bar 12 that is coiled in a circuitous manner. The structural column 1 uses its own strength and pulls the wall 3 through the second steel bar 31 to disperse the load, thereby ensuring the stability of the steel column 4 after the fixed connection. This solves the problem that the embedded bolts embedded in the concrete components cannot disperse the large load to ensure the stability of the fixed connection of the steel column.
