[0025] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0028] Referring to Figures 1-5 , it is the first embodiment of the present utility model. This embodiment provides a prefabricated and assembled semi-rigid beam-column seismic structure, including

[0029] A vertical beam assembly 100, including a steel pipe column 101, a sleeve 102 movably installed on the side wall of the steel pipe column 101, and a reinforcing plate 103 fixedly installed on the side wall of the sleeve 102;

[0030] A cross beam assembly 200, including a cross beam main body 201 and a connecting member 202 welded to the end of the cross beam main body 201. The connecting member 202 is clamped on the outer side wall of the sleeve 102, and an arc-shaped surface structure matching the sleeve 102 is provided on the side wall of the end of the connecting member 202.

[0031] Among them, the vertical beam assembly 100 composed of the steel pipe column 101, the sleeve 102 and the reinforcing plate 103 is used to cooperate with the installation of the cross beam assembly 200. The sleeve 102 facilitates the adjustment of the installation height of the cross beam assembly 200 along the steel pipe column 101 to meet different installation requirements. The sleeve 102 is butt-jointed and installed with the connecting piece 202 at the end of the cross beam main body 201, which can maintain the stability of the position of the cross beam main body 201 and prevent the cross beam main body 201 from loosening. The reinforcing plate 103 installed on the side wall of the steel pipe column 101 and matched with the side wall of the sleeve 102 can improve the pressure-bearing capacity of the sleeve 102 and reduce the possibility of the sleeve 102 deforming under force. The connecting piece 202 is used to butt-joint the cross beam main body 201 with the sleeve 102 and the steel pipe column 101. The assembled steel structure beam-column joint composed of the matching vertical beam assembly 100 and cross beam assembly 200 has a clear force transmission path, reliable connection and good load-bearing capacity. When using this new type of steel structure assembled beam-column joint, enhanced connection or dog-bone connection or increasing the thickness of the circular steel pipe column 101 and the sleeve 102 can be adopted to improve the energy dissipation capacity and seismic performance of the structure.

[0032] Specifically, the connecting piece 202 is fixedly connected to the sleeve 102 by bolts, and the connecting piece 202 and the side wall of the sleeve 102 are provided with a matching bolt hole structure.

[0033] Among them, the sleeve 102 is butt-jointed and installed with the connecting piece 202 at the end of the cross beam main body 201, which can maintain the stability of the position of the cross beam main body 201 and prevent the cross beam main body 201 from loosening. Adding a bolt hole structure facilitates the butt-joint of the sleeve 102 and the connecting piece 202 and improves the butt-joint accuracy.

[0034] Furthermore, the cross beam main body 201 is of I-shaped steel structure, and one end of the cross beam main body 201 is butt-jointed and installed with two sets of sleeves 102.

[0035] Among them, the two sets of sleeves 102 are connected to one end of the cross beam main body 201 through the connecting piece 202, which can effectively prevent the cross beam main body 201 from undergoing lateral flipping, avoid the cross beam main body 201 from deforming the sleeve 102 under force, and ensure the stability of the connection structure between the cross beam main body 201 and the steel pipe column 101.

[0036] Furthermore, the middle of the reinforcing plate 103 is provided with an arc-shaped edge structure. The middle position of the reinforcing plate 103 is clamped under the sleeve 102, and the end of the reinforcing plate 103 extends to the lower end of the cross beam main body 201.

[0037] Among them, the addition of the arc-shaped edge structure on the side wall of the reinforcing plate 103 facilitates it to be clamped against the side wall of the steel pipe column 101 and butt-jointed with the sleeve 102, providing a stable support foundation for the sleeve 102. The extension of the end of the reinforcing plate 103 to the lower end of the cross beam main body 201 can, on the basis of the connection of the steel pipe column 101, assist the sleeve 102 to provide a certain supporting force for the cross beam main body 201, further improving the stability of the connection structure between the cross beam main body 201 and the steel pipe column 101.

[0038] Preferably, an installation hole 203 is provided in the middle side wall of the crossbeam main body 201, and the installation hole 203 is located on one side of the connecting member 202.

[0039] Among them, by providing the installation hole 203 on the side wall of the crossbeam main body 201, it is convenient to dock with the crossbeam main bodies 201 in other directions, increasing the connection foundation between the crossbeam main bodies 201 and improving stability.

[0040] It should be noted that a support member 104 is fixedly installed on the side wall of the steel pipe column 101. The upper end of the support member 104 is clamped at the bottom of the reinforcing plate 103, and one side of the upper end of the support member 104 is in contact with the side wall of the sleeve 102.

[0041] Among them, by providing the support member 104 on the side wall of the steel pipe column 101, the support member 104 is used to cooperate with the support of the reinforcing plate 103 and the sleeve 102, further supporting components such as the sleeve 102 to prevent components such as the sleeve 102 from loosening.

[0042] Preferably, an installation plate 105 is welded to the top of the steel pipe column 101, and installation hole structures are equally spaced on the side wall of the installation plate 105.

[0043] Among them, by providing the installation plate 105 with installation holes at the top of the steel pipe column 101, it is convenient to install the steel pipe column 101 in the building, form an assembled beam structure with the crossbeam main body 201, provide a support foundation for the building, and improve the seismic performance of the building.

[0044] In summary, in this application, a vertical beam assembly 100 composed of a steel pipe column 101, a sleeve 102, and a reinforcing plate 103 is added to cooperate with the installation of a crossbeam assembly 200. The sleeve 102 facilitates adjusting the installation height of the crossbeam assembly 200 along the steel pipe column 101 to adapt to different installation requirements. The sleeve 102 is butt-jointed and installed with the connecting member 202 at the end of the crossbeam main body 201, which can maintain the stability of the position of the crossbeam main body 201 and prevent the crossbeam main body 201 from loosening. The reinforcing plate 103 installed on the side wall of the steel pipe column 101 and cooperating with the side wall of the sleeve 102 can improve the bearing capacity of the sleeve 102 and reduce the possibility of the sleeve 102 deforming under force. The connecting member 202 is used to dock the crossbeam main body 201 with the sleeve 102 and the steel pipe column 101. The assembled steel structure beam-column joint composed of the matching vertical beam assembly 100 and crossbeam assembly 200 has a clear force transmission path, reliable connection, and good bearing capacity. When using this new type of steel structure assembled beam-column joint, enhanced connection or dog-bone connection or increasing the thickness of the circular steel pipe column 101 and the sleeve 102 can be adopted to improve the energy dissipation capacity and seismic performance of the structure.
