Description

Technical Field

[0001] This invention belongs to the field of vibration reduction and seismic resistance technology, and relates to a cylindrical self-resetting rotating energy-dissipating vibration-damping support component. Background Technology

[0002] With the development of prefabricated technology, building structural components are required to be easy to install, easy to replace, and easy to construct, especially for non-structural components and connectors of building structures.

[0003] Furthermore, with the continuous development of building systems, the constant breakthroughs in building height, and the continuous updating of building structural forms, new requirements have been placed on the seismic performance of structures. Compared to structural components, non-structural components such as partition walls and infill walls, due to their lower stiffness, poorer integrity and deformation capacity, are prone to collapse under earthquake action, resulting in serious casualties and huge economic losses. Utilizing such non-structural components to reduce post-earthquake losses has become a new trend. Energy dissipation and vibration reduction technology is a safe and effective engineering seismic resistance method that has developed rapidly in recent years. This method designs certain non-structural components as energy-dissipating elements to reduce the representative value of gravity load on the structure under seismic action, thereby mitigating damage to the main structure. How to introduce the concept of energy dissipation and vibration reduction into non-structural components, making them a controllable energy-dissipating unit that maintains its architectural function under minor earthquakes and realizes its structural function under moderate and major earthquakes—that is, improving the seismic performance of the main structure while undergoing orderly self-destruction—is a new trend. Summary of the Invention

[0004] In view of this, in order to solve the problems existing in the prior art, the present invention provides a cylindrical self-resetting rotating energy-dissipating and vibration-damping support component. This energy-dissipating and vibration-damping support component is simple to process, has low cost, is easy to install and replace, and can be built into the building partition wall without occupying extra building space. It can also realize two-stage energy dissipation and vibration reduction of non-structural components, which is economical and reliable.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cylindrical self-resetting rotating energy-dissipating and vibration-damping support component includes two semi-circular sleeves that are connected to each other, and two core columns inserted at both ends of the semi-circular sleeves. Each core column has a threaded groove I at its head, a baffle welded in the middle that abuts against the inner wall of the semi-circular sleeve, and a support connector at its tail. A set of disc springs is installed on each core column before and after the baffle. A rotating nut is threaded to the head of each core column. A ring friction plate that abuts against the inner wall of the semi-circular sleeve is welded circumferentially to the end of the rotating nut near the disc spring. A torsion steel pipe is fixedly connected between the rotating nuts. A threaded groove II that matches the threaded groove I at the head of the core column is opened inside the rotating nut. The threaded groove I and the threaded groove II are connected to form an outer pipe. An inner pipe is opened in the inner wall of the rotating nut. The inner pipe is connected to the outer pipe and a ball bearing is installed in the pipe.

[0007] Furthermore, each semi-circular sleeve has four limiting plates on its inner side, arranged in two pairs, with each pair of limiting plates forming an insertion groove; the baffle in the middle of the core column is located between the end of the semi-circular sleeve and the limiting plate, and the annular friction plate welded circumferentially to the end of the rotating nut near the disc spring is inserted into the insertion groove formed by the corresponding limiting plate.

[0008] Furthermore, the baffle in the middle of the core column abuts against the inner wall of the semi-circular sleeve, and the annular friction plate welded circumferentially to the rotating nut abuts against the inner wall of the semi-circular sleeve.

[0009] Furthermore, a flange plate I is integrally formed and welded to the outer side of the semi-circular sleeve along its length. Several threaded holes are opened on the flange plate I along its length. Suitable bolts and fasteners are inserted into the threaded holes to fix the upper and lower semi-circular sleeves together to form a cylinder.

[0010] Furthermore, a semi-circular arc groove is provided at the end of the semi-circular sleeve. After the two semi-circular sleeves are joined together, a circular hole is formed at the end of the cylinder. The diameter of the circular hole is slightly larger than that of the core column, and the core column can move along the circular hole within a certain length range.

[0011] Furthermore, flange plate II is integrally formed and welded to the ends of the rotating nuts that are close to each other, and flange plate III is integrally formed and welded to both ends of the torsion steel pipe. Several corresponding threaded holes are evenly opened in the circumference of flange plate II and flange plate III. Suitable bolts and fasteners are inserted into the threaded holes to realize the fixed connection between the rotating nuts and the torsion steel pipe.

[0012] Furthermore, the torsion steel pipe is a mild steel capable of undergoing plastic deformation.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. In the cylindrical self-resetting rotating energy-dissipating vibration damping support component disclosed in this invention, under small earthquakes, the rotating nut and the torsion steel pipe do not work, and the self-resetting of the support component mainly relies on the cooperation of the disc spring and the baffle. Under moderate and large earthquakes, relative movement occurs between the prefabricated partition wall and the beams and columns of the building. Energy dissipation and vibration damping mainly rely on the friction energy dissipation between the annular friction plate and the limiting plate and the metal deformation energy dissipation of the torsion steel pipe to form a dispersed local frequency-modulated mass damping, thereby realizing energy dissipation and vibration damping of non-structural components.

[0015] 2. The cylindrical self-resetting rotating energy-dissipating and vibration-damping support component disclosed in this invention can be installed between partition walls and beams / columns, concealed within the structural partition wall without occupying additional building space. It can achieve energy dissipation and vibration reduction of non-structural components, while installation does not occupy additional building space. The prefabrication and installation of partition walls effectively ensures the uniformity of partition wall quality, improves construction speed, and increases the standardization of components. Furthermore, this energy-dissipating and vibration-damping support component has a simple structure and low cost, facilitating its widespread application and promoting the use of energy-dissipating and vibration-damping elements and prefabricated partition walls.

[0030] like Figures 1-2 The cylindrical self-resetting rotational energy-dissipating and vibration-damping support component shown includes two interconnected upper and lower sections, such as... Figure 3The diagram shows a semi-circular sleeve 1 and core posts 2 inserted at both ends of the semi-circular sleeve 1. A flange plate I11 is integrally welded to the outer side of the semi-circular sleeve 1 along its length. Several threaded holes are formed on the flange plate I11 along its length, into which suitable bolts are inserted to securely connect the upper and lower semi-circular sleeves 1 together to form a cylindrical body. A semi-circular arc-shaped groove is formed at the end of each semi-circular sleeve 1. After two semi-circular sleeves 1 are joined, a circular hole is formed at the end of the cylindrical body. The diameter of this circular hole is slightly larger than that of the core post 2, allowing the core post 2 to move along the circular hole within a certain length range. Four limiting plates 12 are provided on the inner side of each semi-circular sleeve 1. The four limiting plates 12 are arranged in two pairs, with an insertion groove formed between each pair of limiting plates 12.

[0031] like Figure 4 The core column 2 shown has a threaded groove I22 at its head, a circular baffle 21 welded in the middle, and a support connector at its tail. The threaded groove I22 on the core column 2 is not continuous and the thread pitch on the threaded groove I22 is relatively large. When installing two core columns 2, they are placed head to head with a certain distance between them (for axial compression). The baffle 21 in the middle of the core column 2 is located between the end of the semi-circular sleeve 1 and the limiting plate 12. A set of disc springs 3 passes through the core column 2 before and after the baffle 21. Figure 8 The disc spring 3 shown is composed of several disc spring plates 31. As the main self-resetting component of the support member, the disc spring 3 provides bidirectional restoring force to the support member. The disc spring 3 is pre-compressed during installation to improve the initial stiffness of the support. The remaining compressibility (distance) of the disc spring 3 after pre-compression should match the pre-reserved distance between the head-to-head core columns 2. When the support member is under compression, the two core columns 2 move towards each other, further compressing the two inner sets of disc springs 3, while the two outer sets of disc springs gradually relax; when the support member is under tension, the two core columns 2 move away from each other, further compressing the two outer sets of disc springs, while the two inner sets of disc springs gradually relax.

[0032] Both heads of the core column are threaded together as follows Figures 5-6 The rotating nut 4 shown has an annular friction plate 41 welded circumferentially to one end near the disc spring 3. The annular friction plate 41 is inserted into the insertion groove formed by the corresponding limiting plate 12. During assembly, the annular friction plate 41 of the rotating nut 4 is placed between the two limiting plates to restrict the axial movement of the rotating nut 4, but does not restrict its rotation. When this energy-dissipating and vibration-damping support component is working, the core column 2 generates axial movement, which drives the rotating nut 4 to rotate through the threaded connection. As a result, friction is generated between the annular friction plate 41 of the rotating nut 4 and the limiting plate 12 (the magnitude of the friction changes with the magnitude of the support output force; the friction contact surface is different under tension and compression of the support).

[0033] The ends of the rotating nuts 4 that are close to each other are integrally formed and welded with flange plate II 42. The rotating nuts 4 are fixedly connected as follows: Figure 7The torsion steel pipe 5 shown has flange plates Ⅲ51 integrally welded to both ends. Flange plates Ⅱ42 and Ⅲ51 have several corresponding threaded holes evenly spaced circumferentially. Suitable bolts are inserted into these threaded holes to achieve a fixed connection between the rotating nut 4 and the torsion steel pipe 5. The torsion steel pipe 5 is made of mild steel that easily undergoes plastic deformation. When this energy-dissipating and vibration-damping support component is working, the two ends of the torsion steel pipe 5 are subjected to torques in different directions, resulting in pure torsion within the pipe, which dissipates energy through metal deformation. The flange plates serve as the element for bolting the rotating nut 4 to the torsion steel pipe 5. When the two rotating nuts 4 are working, their rotation directions are opposite.

[0034] The rotating nut 4 has a threaded groove II 43 inside that matches the threaded groove I 22 at the head of the core 2. The threaded groove I 22 and the threaded groove II 43 are connected to form an outer pipe. The inner wall of the rotating nut 4 has an inner pipe 44 that is connected to the outer pipe, so that the threaded groove I 22 and the threaded groove II 43 are connected end to end to form a pipe. The pipe is equipped with balls, which circulate through the inner and outer pipes. The balls serve as a connection and force transmission element between the core 2 and the rotating nut 4, and also convert the friction between the core 2 and the rotating nut 4 from sliding friction to rolling friction, which greatly reduces the frictional resistance between the core 2 and the rotating nut 4.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
