[0029] This embodiment introduces a seismic-resistant structure for prefabricated buildings. This structure is suitable for steel structure prefabricated buildings, especially the structural design of the beam-column joints of steel structures. This technology fully considers the compatibility issues of assembly convenience and seismic performance, which will be explained in detail in the following paragraphs.

[0030] Example 1, this example is in conjunction with the appendix to the instruction manual. Figure 1 To be continued Figure 4 In order to fully understand the structure.

[0031] This seismic-resistant structure involves steel columns 100, steel beams 200, and steel brackets 300. The steel columns 100 are rectangular or circular steel columns. Similar to conventional methods, steel brackets 300 are pre-installed on these columns by welding. However, in this embodiment, the structure of the steel brackets is specially designed. Correspondingly, the beam ends of the steel beams that mate with the steel brackets are also specially designed. This embodiment focuses on a detailed description of the mating structure between the beam ends and the steel brackets.

[0032] In this embodiment, the steel bracket 300 includes a bracket body 310 and a mounting part 320. The bracket body has an I-shaped or F-shaped cross-section, with one end horizontally welded to the steel column 100 and the other end serving as the mounting part 320. (Refer to...) Figure 1 The mounting part is a pointed structure protruding outward from the upper and lower inclined surfaces, that is, the mounting part 320 is a convex "V" shaped structure, and bolt holes are provided on the upper and lower inclined surfaces of the mounting part for the installation of high-strength bolts 500.

[0033] Correspondingly, insertion portions 210 are provided at both ends of the steel beam 200. These insertion portions 210 have a concave "V"-shaped structure, meaning they are concave structures formed by an upper and lower inclined surface. These insertion portions mate with the mounting portions of the steel brackets, and bolt holes are provided in these insertion portions. (Refer to...) Figure 1 , Figure 1 The mounting and plug-in parts are plugged in horizontally. That is, the turning line of the aforementioned V-shaped structure is set horizontally. This structural design allows for rapid plug-in assembly, and high-strength bolts are used for auxiliary tightening after installation to complete the connection between the steel beam and the steel bracket.

[0034] Further, a damping alloy sheet 400 is arranged between the insertion part and the mounting part, the damping alloy sheet is a rectangular sheet, the damping alloy sheet is a sheet structure formed by stamping, the damping alloy sheet has a wave-shaped uneven structure, and a damping space is formed between the insertion part and the mounting part.

[0035] Further, the material of the damping alloy sheet is copper alloy or aluminum alloy.

[0036] Further, the damping alloy sheet 400 can be effectively replaced by a damping rubber pad.

[0037] Compared with the traditional flat butt joint, the V-shaped insertion cooperation has a limiting effect on the gravity direction, and the anti-seismic principle is that when the vibration occurs, a small vibration is generated between the steel beam and the steel bracket, and the vibration energy is partially absorbed by the damping alloy sheet or the damping rubber pad, so that the anti-seismic energy absorption effect is realized.

[0038] Another technical effect of the embodiment is that the structure has an automatic reset function when an earthquake occurs, specifically, when the steel beam and the steel column have a small vibration in the horizontal direction, the steel beam and the steel bracket have a relative movement, and when the vibration ends, the wedge-shaped automatic reset occurs between the mounting part and the insertion part of the V-shaped insertion cooperation, so that the automatic reset of the steel beam is ensured, and the beam falling accident is avoided.

[0039] Embodiment two

[0040] Reference Figure 5 The difference between the embodiment and the embodiment one is that the V-shaped structure of the mounting part and the insertion part is reversed in the embodiment, that is, Figure 5 The insertion part 210 of the steel beam 200 at both ends is an outwardly convex V-shaped structure, and the mounting part 320 of the bracket 300 is an inwardly concave V-shaped structure, and the same technical effect as the embodiment one can be achieved.

[0041] The above-described embodiments only describe the preferred embodiments of the utility model, and do not limit the scope of the utility model, and under the premise of not departing from the design spirit of the utility model, various deformations and improvements of the utility model by the related technicians in the field shall fall within the protection scope determined by the claim of the utility model.
