Description

Technical Field

[0001] The utility model relates to an earthquake-resistant frame column structure of a concrete building, belonging to the field of building structures. Background Art

[0002] When a building frame faces factors such as earthquakes, the frame columns located at the four corners of the frame structure will bear the shear load first. Therefore, as an important component to ensure vertical bearing and structural lateral force resistance, the frame columns are more important than the frame beams. According to the design concept of earthquake resistance of frame structures, it is necessary to achieve "strong columns and weak beams": the frame columns should be kept relatively intact so that the plastic hinges of the frame structure should first appear on the frame beams. In this case, through the support of the frame columns, the frame beams will not cause a serious collapse even if they are in a shattered state.

[0003] The Chinese patent with the announcement number CN218713932U discloses a structure for strengthening the shear bearing capacity of the core area of ​​the concrete frame node, including a concrete frame column and a concrete frame beam, the connection between the two constitutes the core area of ​​the concrete frame node, the concrete frame column is provided with a tic-tac-toe composite hoop continuously arranged along the column height range, and a steel frame is inserted into the core area of ​​the concrete frame node. The steel frame passes through the core area of ​​the concrete frame node and extends a distance up and down. The shear bearing capacity of the core area of ​​the concrete frame beam-column node is improved by inserting a cross steel frame in the core area and related connection parts; however, for the frame columns located at the four corners of the frame structure, the shear loads they receive are mainly concentrated on the outdoor sides of the frame columns (such as Figure 1 , Figure 2 As shown in the figure, the shear resistance on both sides of the outdoor part of the frame columns at the corners also needs to be strengthened.

After the foundation frame 1 is poured, the barbed hooks exert an upper and lower pulling force on the concrete filling layer 2, thereby improving the anti-cracking ability of the surface concrete to ensure the shear resistance of the frame column 6.
