[0025] Example 1

[0026] like Figure 1-4 As shown, the present invention proposes a beam-column joint connection device for civil engineering buildings with good seismic performance, including a column 1, a sleeve 2, a connecting pipe 3, a beam 4, and a bolt 5;

[0027] The sleeve 2 is fitted onto the top of the column 1 and is tightly connected to the column 1, wherein the top of the sleeve 2 is in a sealed shape;

[0028] The connecting pipe 3 is located on the outside of the sleeve 2 and is hollow in the middle;

[0029] The beam 4 is inserted into the middle of the connecting pipe 3 and is tightly connected to the inner wall of the connecting pipe 3;

[0030] There are multiple bolts 5, which are respectively arranged on the side of the sleeve 2 and the connecting pipe 3 and pass through the column 1 and the beam 4, and are used to fix the column 1 and the sleeve 2 and the connecting pipe 3 and the beam 4 during use.

[0031] In this embodiment, by fixing the connecting pipe 3 to the outside of the sleeve 2 and making the middle of the connecting pipe 3 hollow, the column 1 and the beam 4 are respectively inserted into the inner side of the sleeve 2 and the connecting pipe 3. The bolts 5 pass through the column 1 and the sleeve 2, as well as the connecting pipe 3 and the beam 4, so that the column 1 and the beam 4 are fixedly connected to the sleeve 2 and the connecting pipe 3 respectively. The column 1 and the beam 4 are also tightly connected to the inner wall of the sleeve 2 and the connecting pipe 3 respectively, which effectively enhances the rigidity of the joint and the seismic performance, and ensures the safety and stability of the building structure.

[0032] Example 2

[0033] like Figure 2-4 As shown, the present invention proposes a beam-column joint connection device for civil engineering buildings with good seismic performance. The difference between this embodiment and the first embodiment is that there are multiple connecting pipes 3. The multiple connecting pipes 3 are respectively arranged on the four sides and the top of the sleeve 2, and the top of the connecting pipes 3 on the four sides of the sleeve 2 is flush with the top of the sleeve 2.

[0034] In an optional embodiment, the inner wall of the connecting pipe 3 is provided with a connecting block 9, and one end of the beam 4 is provided with a connecting groove 10. When the connecting pipe 3 and the beam 4 are installed together, the connecting block 9 is accommodated in the connecting groove 10, which is used to increase the connection area between the beam 4 and the connecting pipe 3 during use and improve the stability of the beam 4 installation.

[0035] In an optional embodiment, the length of the sleeve 2 is greater than the width of the connecting pipe 3, and the width of the sleeve 2 is the same as the length and width of the connecting pipe 3. This is so that, in use, the bottom end of the sleeve 2 extends downward at the center of the multiple connecting pipes 3, so that the bolt 5 fixes the sleeve 2 to the column 1.

[0036] In this embodiment, the four sides and top of the sleeve 2 are respectively set in the connecting pipe 3, so that the column 1 is located in the middle of the building for support. In use, the number of connecting pipes 3 can be adjusted according to actual needs, so that the column 1 can be located at the edge of the building for support. The inner wall of the connecting pipe 3 is provided with connecting block 9, and one end of the beam 4 is provided with connecting groove 10. The connecting block 9 and the connecting groove 10 are tightly fitted and connected, which further enhances the strength of the connecting pipe 3 and improves the seismic performance and stability of the overall structure.

[0037] Example 3

[0038] like Figure 2 As shown, this utility model proposes a beam-column joint connection device for civil engineering buildings with good seismic performance. Compared with the first embodiment, the difference in this embodiment is that the top and bottom ends of the side connecting pipe 3 of the sleeve 2 are provided with longitudinal reinforcement 7 that connects to the other connecting pipe 3 and the sleeve 2. The sides of the side connecting pipe 3 of the sleeve 2 are provided with transverse reinforcement 6 that connects to the other connecting pipe 3.

[0039] In this embodiment, the sides of multiple connecting pipes 3 and the sides of the connecting pipes 3 and the sleeve 2 are connected as a whole by the longitudinal reinforcement 7 and the transverse reinforcement 6, which further increases the transverse and longitudinal strength of the connecting pipes 3 and improves the seismic resistance. At the same time, the longitudinal reinforcement 7 can be adjusted (used or removed) according to actual needs to ensure the overall coordination of the connection position.

[0040] Example 4

[0041] like Figure 2 As shown, the present invention proposes a beam-column joint connection device for civil engineering buildings with good seismic performance. The difference between this embodiment and the first embodiment is that a surface layer 8 is provided on the outer side of the column 1 and the beam 4 and on the side of the sleeve 2 and the connecting pipe 3. The outer dimension of the surface layer 8 is the same as the outer dimension of the end of the connecting pipe 3 and the sleeve 2.

[0042] In this embodiment, by providing a surface layer 8 on the outside of the column 1 and the beam 4, and making the outside of the surface layer 8 flush with the ends of the column 1 and the surface layer 8, the aesthetics of the overall structure are improved.

[0043] In this invention, multiple connecting pipes 3 are fixed to the four sides and top of the sleeve 2, ensuring that the contact surface between each connecting pipe 3 and the sleeve 2 is evenly stressed. The connecting pipe 3 has a hollow center, allowing the column 1 and beam 4 to be inserted into the inner sides of the sleeve 2 and connecting pipe 3 respectively, ensuring a tight fit between the column 1 and beam 4 and the inner walls of the sleeve 2 and connecting pipe 3. Simultaneously, connecting blocks 9 are fitted into connecting grooves 10, increasing the strength of the connecting pipe 3. Bolts 5 penetrate the column 1 and sleeve 2, as well as the connecting pipe 3 and beam 4, fixing the column 1 and beam 4 to the sleeve 2 and connecting pipe 3 respectively, thus securing the beam 4 to the sleeve 2 and connecting pipe 3. The connection of column 1 is convenient and quick. At the same time, by setting horizontal bars 6 and longitudinal bars 7 on the sides of the connecting pipe 3, the sides of multiple connecting pipes 3 and the sides of the connecting pipe 3 and the sleeve 2 are connected into a whole, which further improves the lateral and longitudinal strength of the connecting pipe 3, enhances the seismic performance and stability of the overall structure, ensures a firm connection under various loads, and extends the service life. In addition, the longitudinal bars 7 can be used or removed according to actual needs to ensure the overall coordination of the connection position. In particular, the number of connecting pipes 3 can be adjusted according to actual needs so that the column 1 can be located at the edge of the building for support work.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
