[0034] Please see Figures 1 to 3 This application provides a high-strength bolt connection structure for a steel structure sleeve, including a first I-beam 1, a second I-beam 2, a third I-beam 3, a rigid connector 4, a first shock-absorbing steel member 5, and a second shock-absorbing steel member 6. The first I-beam 1 and the second I-beam 2 are connected by the rigid connector 4 and the first shock-absorbing steel member 5, and the second I-beam 2 and the third I-beam 3 are connected by the rigid connector 4 and the second shock-absorbing steel member 6. The upper flanges and lower flanges of adjacent I-beams are connected by the rigid connector 4. The first shock-absorbing steel member 5 is configured to absorb forces in a first direction, specifically... Figure 1 The second shock-absorbing steel component 6 is configured to absorb the force in the second direction, specifically as follows: Figure 1 The force in the Y direction.

[0035] Specifically, the first I-beam 1 and the second I-beam 2, as well as the second I-beam 2 and the third I-beam 3, are rigidly connected by rigid connectors 4. Furthermore, a first shock-absorbing steel member 5 and a second shock-absorbing steel member 6 are respectively provided between the first I-beam 1 and the second I-beam 2, and between the second I-beam 2 and the third I-beam 3. The first shock-absorbing steel member 5 is configured to absorb forces in a first direction. The second shock-absorbing steel member 6 is configured to absorb forces in a second direction. When the rigid connectors 4 between any two I-beams are damaged due to vibration, the first shock-absorbing steel member 5 and the second shock-absorbing steel member 6 function to connect the first I-beam 1, the second I-beam 2, and the third I-beam 3.

[0036] The high-strength bolt connection structure for steel sleeves provided in this application, compared with the prior art, can absorb vibrations in multiple directions, has a good shock absorption effect, and can avoid connection failure. The first shock-absorbing steel component 5 and the second shock-absorbing steel component 6 are made of spring steel.

[0037] In one embodiment of this application, please refer to Figures 1 to 3 The first shock-absorbing steel component 5 includes a first shock-absorbing steel plate 51 and a pair of first connecting plates 52. The pair of first connecting plates 52 are respectively connected to both sides of the first shock-absorbing steel plate 51, and the pair of first connecting plates 52 are respectively connected to the web of the first I-beam 1 and the second I-beam 2.

[0038] With this configuration, after the rigid connector 4 between the first I-beam 1 and the second I-beam 2 breaks, the first I-beam 1 and the second I-beam 2 will be subjected to force. This force can be transmitted to the first shock-absorbing steel plate 51 through the two first connecting plates 52 connected to the webs of the first I-beam 1 and the second I-beam 2. The first shock-absorbing steel plate 51 can absorb the force in the first direction, reduce the vibration and mutual sway between the first I-beam 1 and the second I-beam 2, avoid connection failure, and improve the seismic resistance of the building.

[0039] In one embodiment of this application, please refer to Figures 1 to 3 The first shock-absorbing steel component 5 also includes two pairs of second connecting plates 53. Each first connecting plate 52 has a second connecting plate 53 connected to its two sides. The pair of second connecting plates 53 on both sides of one first connecting plate 52 are connected to the upper and lower flanges of the first I-beam 1, respectively. The pair of second connecting plates 53 on both sides of the other first connecting plate 52 are connected to the upper and lower flanges of the second I-beam 2, respectively.

[0040] In this configuration, in addition to the first connecting plate 52, the first shock-absorbing steel member 5 is also provided with multiple second connecting plates 53 to increase the connection points between the first shock-absorbing steel plate 51 and the first I-beam 1 and the second I-beam 2. This facilitates the transfer of forces from the first I-beam 1 and the second I-beam 2 to the first shock-absorbing steel plate 51, thereby improving the shock absorption effect, reducing the mutual swaying and vibration between the first I-beam 1 and the second I-beam 2, avoiding connection failure, and improving the seismic resistance of the building.

[0041] In one embodiment of this application, please refer to Figures 1 to 3 The first shock-absorbing steel plate 51 has a "W" shaped cross section, and the extension direction of the first shock-absorbing steel plate 51 is parallel to the line connecting the upper and lower flanges of the first I-beam 1.

[0042] With this configuration, the cross-sectional shape of the first shock-absorbing steel plate 51 is set to "W" shape, which facilitates the shock absorption of the first shock-absorbing steel plate 51 and results in a good shock absorption effect.

[0043] Optionally, the cross-sectional shape of the first shock-absorbing steel plate 51 is "U" shaped, and the extension direction of the first shock-absorbing steel plate 51 is parallel to the line connecting the upper and lower flanges of the first I-beam 1.

[0044] With this configuration, the cross-sectional shape of the first shock-absorbing steel plate 51 is set to "U" shape, which facilitates the shock absorption of the first shock-absorbing steel plate 51 and provides a good shock absorption effect.

[0045] In one embodiment of this application, please refer to Figures 1 to 3 The first shock-absorbing steel component 5 includes multiple first shock-absorbing steel plates 51, which are arranged side by side and connected sequentially along the arrangement direction of the first I-beam 1, the second I-beam 2 and the third I-beam 3.

[0046] It should be noted that in this embodiment, two first shock-absorbing steel plates 51 are used as an example. Of course, in other embodiments, depending on the actual application requirements, the first shock-absorbing steel plates 51 can be set to three, four, or other quantities, and this is not a unique limitation.

[0047] Specifically, when the rigid connector 4 between the first I-beam 1 and the second I-beam 2 is damaged due to vibration, when a force in the first direction acts on the first I-beam 1 or the second I-beam 2, one of the first shock-absorbing steel plates 51 is compressed and the other first shock-absorbing steel plate 51 is stretched.

[0048] This configuration, by setting multiple parallel first shock-absorbing steel plates 51, can improve the shock absorption capacity of the first shock-absorbing steel component 5, further reduce the mutual swaying and vibration between the first I-beam 1 and the second I-beam 2, avoid connection failure, and improve the seismic resistance of the building.

[0049] In one embodiment of this application, please refer to Figures 1 to 3 The second shock-absorbing steel component 6 includes at least two second shock-absorbing steel plates 61. One second shock-absorbing steel plate 61 is connected between the two upper flanges of the second I-beam 2 and the third I-beam 3, and the other second shock-absorbing steel plate 61 is connected between the two lower flanges of the second I-beam 2 and the third I-beam 3.

[0051] Specifically, when the rigid connector 4 between the second I-beam 2 and the third I-beam 3 is damaged due to vibration, and a force in the second direction is applied to the second I-beam 2 or the third I-beam 3, one of the second shock-absorbing steel plates 61 is compressed and the other second shock-absorbing steel plate 61 is stretched.

[0052] With this configuration, after the rigid connector 4 between the second I-beam 2 and the third I-beam 3 breaks, the second I-beam 2 and the third I-beam 3 will be subjected to force. This force will be transmitted from each flange of the second I-beam 2 and the third I-beam 3 to the second shock-absorbing steel plate 61. The second shock-absorbing steel plate 61 can absorb the force in the second direction, reduce the vibration and mutual sway between the second I-beam 2 and the third I-beam 3, avoid connection failure, and improve the seismic resistance of the building.

[0053] In one embodiment of this application, please refer to Figures 1 to 3 The second shock-absorbing steel component 6 also includes two pairs of third connecting plates 62.

The third connecting plates 62 on both sides of the other second shock-absorbing steel plate 61 are connected to the lower flanges of the second I-beam 2 and the third I-beam 3, respectively.

[0054] With this configuration, after the rigid connector 4 between the second I-beam 2 and the third I-beam 3 breaks, the second I-beam 2 and the third I-beam 3 are subjected to force. This force is transmitted to the second shock-absorbing steel plate 61 through multiple third connecting plates 62 connected to the flanges of the second I-beam 2 and the third I-beam 3.

Two fourth connecting plates 63 are connected to the web of the second I-beam 2, and the other two fourth connecting plates 63 are connected to the web of the third I-beam 3.

[0056] In this configuration, in addition to the third connecting plate 62, the second shock-absorbing steel member 6 is also provided with multiple fourth connecting plates 63 to increase the connection points between the second shock-absorbing steel plate 61 and the second I-beam 2 and the third I-beam 3. This facilitates the transfer of forces from the second I-beam 2 and the third I-beam 3 to the second shock-absorbing steel plate 61, thereby improving the shock absorption effect, reducing the mutual swaying and vibration between the second I-beam 2 and the third I-beam 3, avoiding connection failure, and improving the seismic resistance of the building.
