Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a metal bending energy dissipation damper. Background Art

[0002] Metal yield damper refers to a displacement-related damper that uses the plastic deformation of metal to dissipate energy. As a damping structure in buildings, the structural principle of metal dampers is to dissipate energy after deformation yielding. Therefore, they usually play a supporting role in normal and small earthquakes, and play an energy dissipation role in large earthquakes. For example, a three-dimensional metal energy dissipation damper with publication number CN107327193B includes an upper connecting plate, a lower connecting plate, U-shaped steel and S-shaped steel, a lateral connecting support column and a central rectangular connecting column; the two straight sections of the U-shaped steel are respectively connected to the upper connecting plate and the lower connecting plate to form a whole, the upper end of the central rectangular connecting column is fixedly connected to the upper connecting plate, and the lower end is suspended; the outer side surface of the straight section at one end of the S-shaped steel is fixedly connected to the outer side surface of the central rectangular connecting column, and the other end is integrated with the lateral connecting support column; the lower end of the lateral connecting support column is fixedly connected to the lower connecting plate; the S-shaped steel is symmetrically arranged around the central rectangular connecting column. Although energy is dissipated by setting up a large number of curved steels, the direction of energy dissipation is not constrained, which can easily lead to uneven transmission of most of the energy, and thus easily cause damage to the energy dissipation structure in one area.

[0018] In order to make the purpose, technical scheme and advantages of the implementation mode of the utility model clearer, the technical scheme in the implementation mode of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation mode of the utility model. Obviously, the described implementation mode is a part of the implementation mode of the utility model, not all of the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the implementation mode of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected implementation mode of the utility model. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Depend on Figures 1 to 3 As shown, an embodiment of the utility model provides a metal bending energy dissipation damper, comprising an energy dissipation member 1 as a core energy dissipation unit and an assembly sleeve plate 2 as a constraint unit; the energy dissipation member 1 comprises an energy dissipation portion 3 located in the middle and connecting portions 4 symmetrically arranged at both ends of the energy dissipation portion 3; the cross section of the energy dissipation member 1 is cross-shaped, the assembly sleeve plate 2 is provided with a cross-shaped constraint groove 5, the energy dissipation portion 3 is arranged on the inner side of the constraint groove 5, and both ends of the constraint groove 5 extend to the connecting portion 4, and the assembly sleeve plate 2 is used to provide lateral support for the energy dissipation member 1. Among them, the connection part 4 is provided with a plurality of bolt holes, and the metal bending energy dissipation damper in this embodiment can be connected between the steel structures on the building as energy dissipation connection nodes by high-strength bolts through the bolt holes on the connection parts 4 on both sides. When the building does not generate external force to cause it to yield, it can be used as a conventional connection structure to shorten the clear span length of a single support, greatly improving the convenience of transporting support components; when the building is subjected to external forces such as earthquakes, it can be used as an energy dissipation node in the building, and the energy dissipation part 1 can be used to consume external energy by using good ductility and plastic deformation. The component sleeve 2 can not only act as a lateral constraint to ensure the overall stability of the damper in normal conditions, but also constrain the energy dissipation part 1 to only dissipate energy in the direction of the constraint guide when the energy dissipation part 1 is compressed or pulled. Thereby, the stability of the entire damper can be increased in normal conditions, the energy conduction direction can be ensured during energy dissipation, and the energy is mainly concentrated on the central axis of the energy dissipation part of the energy dissipation part 1 to dissipate energy evenly and stably, thereby increasing the energy dissipation intensity of the entire damper and ensuring the overall stability and service life.

[0020] Preferably, the energy dissipation part 3 includes two symmetrically arranged hemispherical parts 6, which are formed by two semicircular rings interlaced vertically, and the spherical ends of the two hemispherical parts 6 are connected. After the energy dissipation part 1 is laterally constrained by the assembly sleeve 2, when the connecting part 4 is subjected to external force and transmitted to the energy dissipation part 3, the energy transmitted from the outside can be effectively consumed through the buckling deformation of the hemispherical part 6, and the hemispherical part 6 is formed by two semicircular rings interlaced vertically, and the central axis of the two semicircular rings interlaced can be used as the main force point when the external force is transmitted, and a large amount of energy can be effectively and evenly dispersed to the two semicircular rings for buckling energy dissipation.

[0021] Furthermore, an arc portion 7 is connected between the two hemispherical portions 6. By providing the arc portion 7 between the two hemispherical portions 6, a spacing is provided when the two hemispherical portions 6 are compressed, so that there is more compression space between the two, and the structural strength of the maximum bending part of the hemispherical portion 6 is improved, so as to avoid excessive deformation during bending and cause the energy dissipation portion 3 to collapse quickly, thereby using multiple frequencies of energy dissipation to gradually weaken external energy and improve the service life and maximum force strength of the energy dissipation part 1.

[0022] Preferably, the component sleeve 2 includes a plurality of sleeves 8 and a plurality of high-strength bolts, and the adjacent sleeves 8 are spliced ​​and installed by the high-strength bolts. In this embodiment, the component sleeve 2 is formed by combining and splicing four sleeves 8, wherein the two side ends of two sleeves 8 protrude and extend to one side, so that when spliced ​​with the other two sleeves 8, the protruding parts abut against the end sides thereof, and a gap is left between the two to form a restraining groove 5.

[0023] Preferably, the high-strength bolt passes through the constraint groove 5 and the inner side of the semicircular ring. In this embodiment, while the high-strength bolt passes through the two sleeves 8 for connection, the high-strength bolt passes through the inner side of the semicircular ring, which can be used for position limiting, ensuring that both ends of the assembly sleeve 2 can extend to the connecting portion 4, thereby stably providing effective side support for the energy-absorbing component 1.

[0024] Preferably, the inner side wall of the restraining groove 5 is in close sliding contact with the end surface of the connecting portion 4. In this way, not only can the assembly sleeve 2 provide effective lateral support to the energy absorbing part 1, but also when the energy absorbing part 1 is compressed or stretched inside, the contact part between the energy absorbing part 1 and the assembly sleeve 2 can provide friction, thereby achieving the effect of partial friction energy dissipation, further increasing the overall energy dissipation effect.

[0025] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
