The weight of the floor and the roof is pressed on the beams, and the force on the beams is pressed on the columns, which then transmit the force to the foundation. Therefore, the application of beam-column structure is very important in the main body of building buildings.

[0003] Related technologies such as Chinese patent CN113136944B disclose a building beam-column structure, including vertical columns and cross beams that are perpendicular and connected to each other, the vertical columns include connecting columns and supporting columns with the same structure, the connecting columns are plugged into the supporting columns and positioned by a positioning structure, the positioning structure includes an extension column, a positioning groove and a positioning plate, the extension column is fixed to the connecting column and plugged into the supporting column, the positioning groove is provided on the side wall of the extension column, the positioning plate is rotatably connected to the end side wall of the supporting column, a push rod is fixed to the end of the cross beam, when the extension column is plugged into the supporting column, the push rod abuts against the positioning plate and pushes the positioning plate to rotate until it is tightly attached to the positioning groove, and the push rod is plugged and positioned in the positioning groove and is located at the upper part of the positioning plate.

[0004] In the above-mentioned related technologies, the end of the beam is directly fixedly connected to the column, and often one column needs to be connected to multiple beams. When one of the beams is subjected to vibration impact, the impact force will be directly transmitted to the column. Through the column as a medium for force transmission, other beams connected to the column will also be affected by the vibration. The applicant has conducted research on this. Summary of the invention

[0005] The purpose of the present application is to provide a building beam-column structure and a construction method thereof, which has the effect of reducing the vibration transmission influence between beams connected to the same column.

[0006] In a first aspect, the present application provides a building beam-column structure, which adopts the following technical solution.

[0007] A building beam-column structure comprises columns and cross beams, wherein a plurality of cross beams are provided, and one end of each cross beam is connected to a column, wherein the column comprises a core shaft and a connecting seat, wherein the connecting seat comprises a plurality of members arranged circumferentially around the axis of the core shaft, wherein one end of each cross beam connected to the column is respectively fixedly connected to the upper end of each connecting seat, wherein a first viscoelastic rubber sheet is provided between each connecting seat and the core shaft, wherein two side surfaces of the first viscoelastic rubber sheet are respectively bonded and fixed to the connecting seat and the core shaft, and wherein each connecting seat is restricted to be able to rise and fall only along the axis direction of the core shaft.

[0008] Specifically, the first viscoelastic rubber sheet can be used to achieve an elastic connection between the connecting seat and the core shaft, so that when the connecting seat is impacted, the first viscoelastic rubber sheet can be used to achieve an energy-absorbing and buffering effect, and the ends of each beam are supported respectively by each connecting seat, so that when any beam is affected by vibration, the vibration effect can be reduced to a minimum through the corresponding connecting seat, so that when the vibration force is transmitted to the core shaft, the vibration force is greatly reduced, and when the vibration force is transmitted to other beams through the core shaft, energy-absorbing and shock-absorbing can be performed in turn through other corresponding connecting seats, that is, two consecutive energy-absorbing and shock-absorbing effects are achieved, effectively reducing the effect of vibration transmission between the beams connected to the same column.

[0014] Specifically, a split core shaft can be formed by the shaft body and the mounting seat, so that the end of the beam will not interfere with the limit block when installed on the core shaft, and the positioning connection between the shaft body and the mounting seat can be achieved by the cooperation between the protrusion and the mounting groove.

[0015] Furthermore, a limiting groove is provided on the upper side of the crossbeam, and each limiting block is inserted in the crossbeam through the limiting groove, and a second viscoelastic rubber sheet is provided on one side of each limiting block close to the axis of the core shaft, and the two opposite side surfaces of each second viscoelastic rubber sheet are respectively fixedly bonded to the limiting block and the side walls of the limiting groove.

[0016] Specifically, the limiting groove enables the limiting block to be inserted into the upper end of the beam, and the second viscoelastic rubber sheet can be used to achieve an elastic connection between the limiting block and the limiting groove, so that the limiting block can elastically support and limit the beam in the vertical and horizontal directions.

[0017] Furthermore, a plurality of isolation protrusions are arranged equidistantly around the axis of the core shaft on the outer wall of the core shaft, and each of the isolation protrusions is arranged at intervals from each connecting seat, and a third viscoelastic rubber sheet is arranged between each isolation protrusion and the adjacent connecting seat, and the two side surfaces of each third viscoelastic rubber sheet are fixedly bonded to the isolation protrusion and the connecting seat respectively.

[0018] Specifically, the cooperation between the isolation protrusion and the third viscoelastic rubber sheet bracket can further increase the energy dissipation and shock absorption effect of the connecting seat, and can also isolate any two adjacent connecting seats to avoid mutual interference between any two adjacent connecting seats.

[0019] Furthermore, the shaft body has a connecting hole coaxial with the shaft body, the bottom surface of the mounting seat is provided with an inner shaft inserted in the connecting hole, the inner shaft and the connecting hole are interference fit, and a fourth viscoelastic rubber sheet is provided between each connecting strip and the inner shaft, one side surface of each fourth viscoelastic rubber sheet is respectively bonded to each connecting strip, and the other side surface of each fourth viscoelastic rubber sheet is bonded to the outer wall of the inner shaft.

[0020] Specifically, the fourth viscoelastic rubber sheet can be used to connect the inner shaft and the connecting strip, further increasing the elastic buffering capacity and making the overall elastic supporting effect of the core shaft better.

[0021] In the second aspect, the construction method of the beam-column structure of a building provided by the present application adopts the following technical solution: A construction method based on the above-mentioned building beam-column structure comprises the following steps: S1. Prefabricate and produce various accessories of the column in the factory, and prefabricate and produce the beam; S2, assembling the shaft body, the first viscoelastic rubber sheet and the connecting seat to preliminarily form a column, and installing the column on site; S3, transporting the crossbeam to the site, and fixing the ends of the crossbeam to the connecting pieces on the outer walls of the columns; S4.
