Description

Technical Field

[0001] The utility model belongs to the technical field of structural engineering, and particularly relates to a non-uniform height joint with an H-shaped seismic damper. Background Technique

[0002] With the increasing number of high-rise steel frame structures and the special requirements for the spatial and plane layout of buildings, steel structure buildings are developing towards large-scale and large-span directions, and many structures with complex shapes have emerged. Most steel structures are often of unequal spans. Currently, for the design of such frame structures at home and abroad, steel beams of equal height are usually used to penetrate the entire floor. In the structural system of such a design, the strength of the joint area of the middle column is often weaker than that of the beam, which may lead to shear failure in the joint area. On the premise of ensuring the safety of the structural system, for the parts with small spans, steel beams of unequal height can be used. This design scheme can not only reduce the use of steel and the self-weight of the structural system, but also meet the design requirements of "strong joints, weak members" to the greatest extent.

[0003] Due to the different heights of the beams, this connection structure not only increases the construction difficulty, but also makes the problem of mutual interference in the connection structure in the orthogonal direction prominent. In the prior art, usually, the structure near the joint area adopts the same measures as the equal-height beam-column joint structure, welds the end of the low beam to the T-shaped connecting piece, and connects it to the outer ring plate through high-strength bolts. Although this connection method effectively improves the seismic performance of the non-uniform height joint, the main failure of the test piece is the welding tear between the T-shaped beam and the end of the low beam, and the welding tear speed is very fast.

[0004] In the prior art, seismic dampers are usually used to solve the above problems. However, the existing seismic dampers are usually connected by bolt groups, and the upper and lower ends of the damper cannot be completely connected to the steel beam. After installation, a part of the surface of the damper still cannot be connected to the steel beam, which makes the setting of the damper unstable. Therefore, we propose a non-uniform height joint with an H-shaped seismic damper to solve the above problems. Content of the Utility Model

[0031] Among them, the fixing assembly 4 includes a bearing plate 41, a pressing plate 44, a B-shaped hollow block 45, a ratchet 46, a ratchet tooth 47, a rack 48 and a gear 49.

[0032] Specifically, when installing the damper assembly 3, in order to enable the damper assembly 3 to be stably connected to the steel beam assembly 2, a fixing assembly 4 can be set on the steel beam assembly 2, and the damper assembly 3 is arranged below the fixing assembly 4. By pressing down through the fixing assembly 4, the damper assembly 3 can be stably set.

[0033] Furthermore, when pressing the damper assembly 3, it can be realized by rotating the ratchet 46. Since the ratchet 46 is connected to the gear 49, and the gear 49 meshes with the rack 48, rotating the ratchet 46 can drive the pressing plate 44 to move downward, and then the damper assembly 3 can be pressed. And because the ratchet tooth 47 clamps the ratchet 46, the H-shaped damper 31 can be stably pressed, and then the H-shaped damper 31 can be stably set.

[0034] In this embodiment, the support assembly 1 includes a square steel pipe column 11 and an outer strengthening ring 12. The inside of the square steel pipe column 11 is hollow, and the outer strengthening ring 12 is installed on the square steel pipe column 11.

[0035] Specifically, during specific use, in order to enable the subsequent steel beam assembly 2 to be stably set, the steel beam assembly 2 is installed on the square steel pipe column 11, and then the outer strengthening ring 12 and the steel beam assembly 2 can be connected, so that the steel beam assembly 2 can be stably set.

[0036] In this embodiment, the steel beam assembly 2 includes an A steel beam 21, a B steel beam 22, and an A connecting plate 23. The A steel beam 21 and the B steel beam 22 are respectively arranged at the left and right ends of the outer strengthening ring 12, and both the A steel beam 21 and the B steel beam 22 are connected to the outer strengthening ring 12 through the A connecting plate 23.

[0037] Specifically, when connecting the A steel beam 21 and the B steel beam 22 to the outer strengthening ring 12, an A connecting plate 23 can be set on the A steel beam 21 and the outer strengthening ring 12, and an A connecting plate 23 is also set on the B steel beam 22 and the outer strengthening ring 12, and the A steel beam 21, the outer strengthening ring 12, the B steel beam 22, and the outer strengthening ring 12 are stably connected through a bolt group.

[0039] Specifically, when setting the H-shaped damper 31, in order to enable the H-shaped damper 31 to be stably set, a B connecting plate 32 is set between the H-shaped damper 31 and the outer strengthening ring 12, and the outer strengthening ring 12 and the B connecting plate 32, the H-shaped damper 31 and the B connecting plate 32 are connected through a bolt group, so that the H-shaped damper 31 can be stably set.

[0040] In this embodiment, the H-shaped damper 31 includes an upper flange, a lower flange, and a web. The web is arranged between the upper flange and the lower flange; a plurality of rectangular perforations are formed in the web, and both ends of the rectangular perforations are arc-shaped.

[0041] Specifically, the upper flange of the H-shaped damper 31 is connected to the outer strengthening ring 12 through the B connecting plate 32, and the lower flange of the H-shaped damper 31 is arranged on the B steel beam 22, so that under the action of an earthquake, relative displacement occurs between the upper and lower flanges of the H-shaped damper 31, and the perforated web effectively dissipates seismic energy through shear deformation, making the deformation and energy dissipation of the joint concentrated on the H-shaped damper 31, maintaining the elastic state of the joint, and thus improving the overall seismic performance.

[0042] In this embodiment, the fixing assembly 4 further includes an A hollow block 42 and a telescopic block 43. The A hollow block 42 is installed on the bearing plate 41.

The rotated ratchet 46 is engaged by the ratchet teeth 47, so that the pressing plate 44 can always press the H-shaped damper 31.

[0049] Specifically, similar to the above, in specific use, according to different use requirements and the possible earthquake intensity, the shape and quantity of the perforations provided on the web can be changed, so that it can undergo shear deformation during an earthquake. In this embodiment, it is proposed that the shape of the perforations is a diamond structure.

Through the damper assembly 3, during subsequent use, if an earthquake occurs, relative displacement occurs between the upper and lower flanges of the H-shaped damper 31. The perforated web effectively dissipates earthquake energy through shear deformation, causing the deformation and energy dissipation of the joint to concentrate on the H-shaped damper 31, maintaining the elastic state of the joint, thereby improving the overall seismic performance. And in order to enable the H-shaped damper 31 to be stably installed, a fixing assembly 4 is provided on the B steel beam 22. Through the fixing assembly 4, the H-shaped damper 31 can be pressed, so that the H-shaped damper 31 can be stably installed.
