Problems solved by technology

Because the outer wall of the steel pipe column is higher or equal to the height of the ribs, when welding the cross-shaped plate and the ribs of the steel column in this way, the operation is relatively difficult and the quality is difficult to control

specific Embodiment approach

[0017] The preferred embodiment of the connection limiter for the transition section between the concrete column and the concrete-filled steel tube column of the present invention is:

[0018] The connection limiter is set between the lower concrete column and the upper concrete-filled steel tube column, and includes a ring plate, and ribs and studs are arranged inside the ring plate. The positions, sizes, and The thickness and direction are consistent with the position, size, thickness and direction of the ribs and studs inside the steel tube concrete column, and are used to limit the reinforcement of the concrete column.

[0019] The outer diameter of the steel bar limiter is consistent with the outer diameters of the concrete column and the steel tube concrete column.

[0020] The ring plate has a height of 50mm to 150mm and a thickness of 8mm to 12mm.

[0021] The connection limiter for the transitional section between the concrete column and the steel pipe concrete colum...

specific Embodiment

[0026] The basic composition of the connection limiter used for the transition section between the concrete column and the steel tube concrete column:

[0027] like Figure 5a , Figure 5b , Figure 5c As shown, the connection limiter used for the transition section between concrete columns and CFST columns is mainly composed of three parts: ring plates, rib plates and studs.

[0028] 1) Rib and stud design:

[0029] The position, size, thickness and direction of the ribs and studs should be consistent with the upper steel pipe column, so as to play the role of steel bar limit. The height and thickness of the ribs should be appropriate. In this example, the height of the ribs is 50mm, and the thickness is 10mm. .

[0030] 2) Ring plate design:

[0031] In order to avoid the situation that the concrete column formwork cannot be closed after the steel bar stopper is installed, the outer diameter of the steel bar stopper should be consistent with the outer diameter of the co...

Abstract

The invention discloses a connection limiter used for a transition section of a concrete column and a concrete-filled steel tubular column. The connection limiter is arranged between the concrete column on the lower portion and the concrete-filled steel tubular column on the upper portion, and comprises an annular plate; rib plates and pins are arranged inside the annular plate; and the position, size, thickness and direction of the rib plates and the pins in the annular plate are consistent with those of rib plates and pins inside the concrete-filled steel tubular column, and the rib plates and the pins are used for limiting steel bars of the concrete column. The problem of collision between column rebars of the concrete column and rib plates of the concrete-filled steel tubular column is solved, convenience is provided for positioning and installation of the steel tubular column, the number of measures is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a steel structure construction member, in particular to a connection limiter for the transition section between a concrete column and a steel tube concrete column. Background technique [0002] In the construction of steel structure, at the position where the concrete column and the steel pipe column are connected, if the column reinforcement of the concrete column needs to pass through the steel pipe column, it is easy for the column reinforcement to collide with the inner rib of the steel pipe column. At this time, the concrete column has generally been poured , the column reinforcement is difficult to move, and the steel pipe column is difficult or even impossible to install. [0003] At present, in the transitional section between the concrete column and the concrete-filled steel tube column, the method adopted is generally to embed a section of H-shaped steel with a length of 1500 mm in the concrete column. The embedded le...
