[0003] However, there are some problems with the existing technology: in earthquake disasters, the house shakes at a large angle due to the earthquake. At this time, the stress conditions at each position in the concrete structure frame of the house are different, which leads to different damage conditions at each position of the concrete frame structure. Generally, the stress conditions of the column are greater than the beam, and the collision force at the node between the column and the beam is the greatest, resulting in the serious earthquake damage of the concrete frame mostly occurring at the beam-column node position of the frame.

[0022] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.
[0023] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0025] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0026] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.
[0027] like Figures 1 to 5 As shown, an earthquake-resistant concrete structural frame provided by an embodiment of the utility model, the axial direction of the column 1 is the Z-axis direction, the axial direction of the beam 101 is the X-axis direction, and the axial direction of the longitudinal beam 102 is the Y-axis direction, including the column 1 arranged along the Z-axis direction, the beam 101 arranged along the X-axis direction, the longitudinal beam 102 and the side column 103 arranged along the Y-axis, the column 1 and the side column 103 are arranged in parallel, the column 1 and the side column 103 are connected by the beam 101, and the column 1, the beam 101 and the longitudinal beam 102 are cross-connected.
[0028] Usually when constructing a concrete structure frame, the load-bearing columns are divided into columns 1 and side columns 103. The edges of the frame are side columns 103, and the remaining load-bearing columns are columns 1. Generally, beams are arranged on the four sides of the columns 1, and beams are arranged on only three sides of the side columns 103. In this embodiment, two reinforcement structures of the inner column 1 are described.
[0029] Specifically, a steel-clad structure 2 is provided on the outer side of the column 1 for reinforcing the column 1 . The steel-clad structure 2 includes an angle steel 201 . The angle steel 201 is a right-angle plate. The angle steel 201 fits the corner of the column 1 . There are four angle steels 201 . The four angle steels 201 are evenly distributed on the outer side of the column 1 . A plurality of steel plates 202 are welded between the angle steels 201 . The plurality of steel plates 202 are evenly distributed on adjacent angle steels 201 .
[0030] Furthermore, in an earthquake disaster, the damage to the column 1 is greater than that to the beam. Therefore, in the present embodiment, angle steel 201 and steel plate 202 are arranged on the outside of the column 1 to wrap the column. The right-angle structure of the angle steel 201 can make the angle steel 201 fit the column 1 better, and the steel plate 202 welded between the angle steels 201 can make the angle steel 201 and the column 1 contact more closely, thereby adding a layer of rigid structure to the outside of the column 1 and increasing the bending strength of the column 1.
[0031] Specifically, connectors 3 are provided at the connection points of the column 1, the cross beam 101 and the longitudinal beam 102. The connectors 3 are connected by bolts 4 and are used to reinforce the connection points of the column 1, the cross beam 101 and the longitudinal beam 102. The connector 3 includes a reinforcing plate 301. The reinforcing plate 301 is configured as a right-angle plate. The connector 3 is composed of three reinforcing plates 301 connected together. The three reinforcing plates 301 are vertically connected to each other in a right-angle coordinate system. Connecting plates 302 are fixedly connected between adjacent reinforcing plates 301. In order to increase the connection strength between the reinforcing plates 301, through holes 303 are opened on the connecting plates 302.
[0032] Furthermore, in an earthquake disaster, both columns and beams will be damaged, so the damage at the node position is particularly obvious. In order to ensure the strength of the node, connectors 3 are set at the connection points of the column 1, the cross beam 101 and the longitudinal beam 102. The connectors 3 are distributed at the eight intersections of the column 1, the cross beam 101 and the longitudinal beam 102, and are connected by bolts 4 respectively. The right-angle structure of the three reinforcement plates 301 on the connector 3 can fit the cross beam 101 and the longitudinal beam 102, and can clamp the steel structure 2 on the outside of the column 1, which is equivalent to the connector 3 clamping the connection point of the column 1 through connection, strengthening the strength of the intersection of the column 1, thereby improving the seismic performance of the concrete frame structure.
[0033] Specifically, one side of the X-axis of the side column 103 is connected to the cross beam 101, longitudinal beams 102 are arranged on both sides of the Y-axis of the side column 103, a steel structure 2 is arranged on the column 1, and connecting parts 3 are arranged at the intersection points of the side column 103 and the cross beam 101, and the connecting parts 3 are connected by bolts 4. A side plate 5 is arranged on the other side of the X-axis of the side column 103, and the connecting part 3 and the side plate 5 are connected by bolts 4.
[0034] Furthermore, for the side column 103 located at the edge of the concrete frame structure, since there is no cross beam 101 on the outside of the side column 103, a side plate 5 is set on the outside of the steel structure 2 on the side column 103, and a connecting piece 3 is set at the intersection of the cross beam 101, the side column 103 and the longitudinal beam 102 on the other side. The connecting piece 3 and the side plate 5 are connected by bolts 4, so that the steel structure 2 and the side plate 5 strengthen the strength of the outside of the side column 103, and the strength of the intersection of the side column 103 is strengthened by the connecting piece 3.
[0035] Working principle: In an earthquake disaster, both columns and beams will be damaged, so the damage at the node position is particularly obvious. In order to ensure the strength of the node, connectors 3 are set at the connection points of the column 1, the cross beam 101 and the longitudinal beam 102. The connectors 3 are distributed at the eight intersections of the column 1, the cross beam 101 and the longitudinal beam 102, and are connected by bolts 4 respectively. The right-angle structure of the three reinforcement plates 301 on the connector 3 can fit the cross beam 101 and the longitudinal beam 102, and can clamp the steel structure 2 on the outside of the column 1, which is equivalent to the connector 3 clamping the connection point of the column 1 through connection, strengthening the strength of the intersection of the column 1, thereby improving the seismic performance of the concrete frame structure.
