Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering, and in particular to a vertical tension-compression limited energy-absorbing and seismic-isolating bearing device and a manufacturing method thereof. Background Art

[0002] Vertical seismic isolation / vibration bearings are devices specifically designed to isolate and reduce vertical vibration and impact on structures. They are an important supplement to traditional horizontal isolation systems, especially when addressing scenarios such as ground motion (which contains a significant vertical component), rail transit vibration, and mechanical vibration.

[0003] Vertical seismic isolation / vibration bearings significantly attenuate vertical accelerations, velocities, and displacements transmitted from foundations (such as the ground and bridge piers) to superstructures (such as building floors, bridge superstructures, and precision equipment). They are particularly suitable for situations where seismic motion has a strong vertical component (near-fault earthquakes and certain geological conditions), as well as for sustained or impactful vertical vibrations caused by subways, trains, heavy machinery, and other sources. By reducing the vertical forces (inertia) transmitted to the superstructure, they significantly reduce the risk of damage, cracking, or even failure of structural components (columns, walls, beams, and floor slabs) and their connections under intense vertical vibration, thereby improving the overall seismic performance and safety of the structure. Furthermore, since vertical inertia is significantly reduced, the axial forces, bending moments, and shear forces that structural components (particularly columns and foundations) must withstand are also reduced. This can lead to structural design optimizations, such as reducing component cross-sections and reinforcement requirements, or, under the same conditions, creating taller or lighter structures.

[0004] Traditional structures rely primarily on their inherent strength, stiffness, and ductility to dissipate energy, protecting the main structure by "hardly resisting" earthquake forces. However, strong earthquakes can still cause structural damage and interrupt functionality, making it difficult to protect the precision equipment and personnel within.

[0005] Furthermore, strong earthquakes can cause localized uplift of structures, generating tensile forces. Many vertical seismic isolation bearings (especially rubber bearings and certain friction pendulums) have very limited tensile strength or are completely incapable of withstanding such forces. Therefore, improving the efficiency of existing devices in dissipating vertical high-frequency energy and their tensile strength is a pressing issue for those skilled in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide a vertical tensile and compressive limited energy-absorbing seismic isolation bearing device and a manufacturing method thereof, in order to solve the technical problem that the traditional structural seismic resistance mainly relies on the strength, stiffness and ductility of the structure itself to dissipate energy, and protects the main structure by hard resisting earthquake forces, but may still cause structural damage and functional interruption under strong earthquakes, and is difficult to protect the internal precision equipment and personnel safety. It is also necessary to solve the problem that the traditional seismic-resistant structure is partially pulled up by strong earthquake vibrations, generating tension, and the tensile capacity of many vertical seismic isolation bearings (especially rubber bearings and certain friction pendulums) is very limited or cannot withstand tension at all.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions.

[0011] Preferably, the high-damping viscoelastic layer is connected to the inner plate via epoxy resin glue, polyurethane glue or acrylate glue; the high-damping viscoelastic layer is made of high-damping rubber or polyurethane.

[0012] Preferably, to prevent delamination of the high damping viscoelastic layer from the outer plate, the spacing between adjacent bolts is less than or equal to 5 times the thickness of the high damping viscoelastic layer; the length of the bolts is equal to the thickness of the outer plate plus half the thickness of the high damping viscoelastic layer.

[0013] Preferably, upper stiffening ribs are provided at intervals between the bottom of the upper connecting plate and the inner plate on the opposite side; lower stiffening ribs are provided at intervals between the fixed portion of the lower connecting plate and the outer plate on the opposite side.

[0014] Preferably, the contact surface between the high damping viscoelastic layer and the outer plate is provided with a cross groove, the depth of the cross groove is 0.2-0.5 mm, the density is 20-50 / cm², and the surface of the bolt is prefabricated with a spiral glue guide groove, the groove depth of the glue guide groove is 0.1-0.3 mm.

[0015] Preferably, a bushing is provided between the spring and the inner partition, and the inner wall of the bushing is coated with a molybdenum disulfide lubricating layer.

[0016] A method for manufacturing a vertical tension-compression limited energy-absorbing seismic isolation bearing device comprises the following steps.

[0017] Step 1: Make the main load-bearing frame: Integrate the upper connecting plate, inner side plate and inner partition plate into one piece.

[0018] Step 2: Use high-performance adhesive to bond the high-damping viscoelastic layer to the inner panel.

[0023] Compared with the prior art, the present invention has the following characteristics and beneficial effects.

[0024] 1. The device of the present invention constructs a dual energy dissipation path through a high-damping viscoelastic layer and springs. On the one hand, it effectively absorbs high-frequency vertical kinetic energy in earthquakes, achieving energy dissipation and vibration reduction. On the other hand, it limits the pull-out displacement of the upper and lower components through a flexible tension-limiting device (such as a steel wire bundle or high-strength fiber), fundamentally compensating for the insufficient tensile strength of traditional rubber bearings and effectively preventing structural damage due to upward pull during earthquakes. It combines vertical energy dissipation with tensile-limiting functions, improving vertical seismic isolation performance. The device utilizes a combination of a metal frame, elastic elements, and damping modules, which not only meets high-performance requirements but also offers good cost control. It is suitable for a variety of scenarios, including buildings, bridges, high-speed rail stations, and precision equipment foundations in high-intensity earthquake zones, and has broad prospects for promotion.

[0025] 2. The present invention utilizes a coordinated spring-limiter-damper design to create an active reset mechanism. The vertical spring within the device and its connection to the upper and lower connecting plates form an axial elastic reset system, enabling the device to actively reset after vertical disturbances, preventing residual displacement accumulation. The spring also provides additional damping for low- and medium-amplitude vibrations.

[0026] 3. The high-damping viscoelastic layer of the present invention offers a stable structure and excellent resistance to delamination and debonding. Made of high-damping rubber or polyurethane, the high-damping viscoelastic layer is connected to the inner and outer panels via a composite epoxy adhesive and bolt fastening structure, significantly enhancing the strength and durability of the connection. In particular, the composite glue injection and bolt fastening structure between the outer panel and the viscoelastic layer effectively prevents debonding failure under high-intensity conditions.

[0027] 4. The present invention's microstructural design enhances bonding and interfacial strength. The inventors incorporated a cross-grooved microstructure on the interface between the outer plate and the high-damping viscoelastic layer to increase interfacial contact area and bond strength. A spiral glue guide groove is incorporated into the bolt thread area to facilitate uniform colloid distribution, improve overall interfacial bonding strength, and effectively mitigate the risk of delamination. Furthermore, the inventors' structural sliding friction-reducing design enhances the durability of the device. A polytetrafluoroethylene sliding bushing is installed between the spring and the inner partition, and its inner wall is coated with a molybdenum disulfide lubricating layer. This reduces metal wear and jamming during repeated operation, extending the device's service life.

[0028] 5. The standardized structure and step-by-step construction method of the present invention facilitate assembly and maintenance. Through modular design and clear construction steps, such as "first making the main load-bearing frame - bonding the damping layer - composite connecting the outer plates - welding the lower connecting plate - installing the limit device", the manufacturing and installation process of the entire device has good adaptability to factory prefabrication and on-site assembly, which significantly reduces the difficulty and construction period of on-site construction.
