Description

Technical Field

[0001] This utility model relates to the technical field of buckling restraint support devices, and in particular to a buckling restraint damping support device. Background Technology

[0002] Buckling-restrained braces (BRBs) have good ductility and energy dissipation capacity and are widely used in building structures. However, current BRBs have large residual deformation after yielding in earthquakes, which can affect the post-earthquake functionality of buildings. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a buckling-restrained damping support device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A buckling-restrained damping brace includes:

[0006] The intermediate cylinder has a second butyl rubber structure inside.

[0007] Two cylinders are positioned at opposite ends of the middle cylinder:

[0008] A large cross-shaped steel plate is set inside a cylinder, and several trapezoidal holes are distributed in a strip on its surface. Its tail is connected to the second butyl rubber structure through a baffle.

[0009] A circular push plate is located at the head of the large cross-shaped steel plate body;

[0010] Several horizontal plates are set on the side wall of a circular push plate, and a second butyl rubber structure is set between adjacent horizontal plates;

[0011] The connector is located at the head of the horizontal plate and is equipped with a pin.

[0012] The cylindrical tube and the intermediate tube are connected by threads.

[0013] The inner wall of the cylinder has four grooves arranged in a ring to fit the large cross-shaped steel plate.

[0014] The tail of the large cross-shaped steel plate is connected to the baffle via a small cross-shaped steel plate.

[0015] A limit baffle is provided at the connection between the cylindrical tube and the intermediate tube.

[0016] A rubber ring is provided at the connection between the baffle and the cylinder.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model adopts a combination of metal damper and rubber. Butyl rubber has good elasticity and flexibility at both room temperature and low temperature. When the metal damper yields in shear, the butyl rubber can provide a rebound force to reduce the residual deformation of the metal damper.

[0019] 2. This utility model provides lateral stiffness to the building structure, reduces the damage to the structure caused by earthquakes, and protects the safety of the main structure, so as to achieve the design principle of "no damage in small earthquakes, repairable in moderate earthquakes, and no damage in large earthquakes", while ensuring that the structure has sufficient strength and ductility and meets the functional requirements of the building.

[0020] 3. This utility model is mainly used for buckling restraint bracing in frame structures. When the structure is subjected to significant external forces, this utility model can provide lateral stiffness in a timely manner without the bracing itself buckling. It dissipates energy through its own metal strip shear deformation and the compression and shear toughness deformation characteristics of butyl rubber.

[0021] 4. Compared with traditional buckling bracing, this utility model adds butyl rubber as an auxiliary energy dissipation material. A large cross-shaped steel plate with trapezoidal holes is inserted into the cylinder, which increases the out-of-plane stiffness. While the strip energy dissipation beam on the steel plate in the buckling bracing plane undergoes shear yielding, the butyl rubber can also undergo shear deformation and compression rebound to provide damping force, thereby achieving the effect of energy dissipation and vibration reduction.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0029] like Figures 1 to 5 As shown, a buckling-restrained damping support device includes: an intermediate cylinder 8, with a second butyl rubber structure 13 disposed inside; two cylinders 4, respectively disposed at both ends of the intermediate cylinder 8; a large cross-shaped steel plate 12 disposed inside the cylinder 4, with several trapezoidal holes 5 distributed in a strip on its surface, and its tail connected to the second butyl rubber structure 13 via a baffle 9; a circular push plate 3 disposed at the head of the large cross-shaped steel plate 12; several horizontal plates 1 disposed on the sidewall of the circular push plate 3, with a second butyl rubber structure 2 disposed between adjacent horizontal plates 1; and a connecting piece 11 disposed at the head of the horizontal plate 1, with a pin disposed thereon. The cylinders 4 and the intermediate cylinder 8 are threadedly connected. The inner wall of the cylinder 4 has four grooves distributed in a ring to fit the large cross-shaped steel plate 12. The tail of the large cross-shaped steel plate 12 is connected to the baffle 9 via a small cross-shaped steel plate 10. A limit baffle 6 is provided at the connection between the cylinder 4 and the intermediate cylinder 8. A rubber ring 7 is provided at the connection between the baffle 9 and the cylinder 4.

[0030] Among them, the large cross-shaped steel plate 12 has several trapezoidal holes 5 distributed in a strip on the steel plate surface to form an energy-dissipating beam. The circular push plate 3 is welded to the large cross-shaped steel plate 12. The baffle 9 is tightly attached to the small cross-shaped steel plate 10 without connection. The large cross-shaped steel plate 12 is inserted into the cylinder 4 of chamber I. The cylinder 4 has a groove that matches the large cross-shaped steel plate 12. The limiting baffle 6 prevents the large cross-shaped steel plate 12 from moving forward in the cylinder 4. Only the small cross-shaped steel plate 10 is close to the baffle 9 of chamber II. The second butyl rubber structure 13 is bonded to the baffle 9. The two cylinders of chamber I 4 are threadedly connected to the intermediate cylinder 8 of chamber II. As the threads are tightened, the baffle 9 and the small cross-shaped steel plate 10 are squeezed tightly against each other.

[0031] When this utility model is in use, when the frame structure is subjected to earthquake or wind loads, the utility model in the structure provides lateral resistance in the frame plane. The axial force is transmitted to the utility model through the pins. At this time, the second butyl rubber structure 2 and the horizontal plate 1 shear and shift against each other. The butyl rubber has toughness and generates rebound to resist a small part of the force. The remaining force is resisted by the shear deformation of the large cross-shaped steel plate 12 in the cylinder 4 of chamber I. Finally, the remaining small part of the force is transmitted to the cylindrical second butyl rubber structure 13 in the cylinder 4 of chamber II through the close-fitting baffle 9. The butyl rubber consumes the force by its own flexibility and generates rebound force, so that the large cross-shaped steel plate 12 returns to its original position.

[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
