Description

Technical Field

[0001] This utility model relates to the field of civil engineering structural technology, and in particular to a cross-shaped insert plate type tension and compression energy dissipation support. Background Technology

[0002] With the rapid advancement of urbanization in my country, a large number of super high-rise buildings, long-span bridges, stadiums, and complex spatial structures are emerging. These buildings have complex structural systems and are massive in size. During their design and service life, they may encounter extreme loads such as strong winds and earthquakes, posing extremely stringent challenges to seismic design. In order to effectively improve the safety performance of building structures and protect people's lives and property, the advanced design concept and technical measures of energy dissipation and vibration reduction have gradually received widespread attention and have been widely applied in practical engineering.

[0003] Traditional seismic damping bearings (such as plate rubber bearings and pot bearings) have long played an important role in various civil engineering projects as key force transmission and energy dissipation components in the seismic resistance system of structures. These bearings mainly dissipate seismic energy through their own elastic deformation or frictional sliding, thereby reducing the seismic forces suffered by the main structure. However, with the accumulation of engineering practice experience and in-depth research, common traditional seismic damping bearings have gradually revealed some inherent problems and limitations in practical applications: 1) Difficulty in balancing vertical tensile and compressive performance with energy dissipation capacity: Many traditional bearings are designed with an emphasis on bearing compression or providing horizontal seismic isolation, and their vertical tensile stiffness and tensile bearing capacity are often insufficient. When an earthquake triggers uplift or strong vertical vibration of the structure, the bearing is prone to failure due to tension or excessive deformation. At the same time, the vertical energy dissipation mechanism of traditional bearings is singular and inefficient, making it difficult to effectively suppress the vertical vibration response of the structure. 2) Low energy dissipation efficiency due to multi-directional coupling: Real seismic forces are multi-dimensional. Traditional bearings typically employ relatively independent, even mutually restrictive, horizontal and vertical energy dissipation mechanisms. This hinders their ability to efficiently dissipate energy in complex, multi-directional coupled vibrations, resulting in suboptimal overall seismic performance. 3) Limited durability and fatigue performance: Especially during rare earthquakes, the internal materials of the bearings undergo large deformations and repeated cyclic loading. Bearings made of a single material (such as pure rubber) are prone to stress concentration and cumulative fatigue damage. Under high-frequency or long-term vibrations, their performance may degrade, affecting the long-term safety of the structure. Given the aforementioned shortcomings of traditional damping bearings, the market urgently needs a new type of bearing that can simultaneously provide reliable vertical tensile and compressive bearing capacity and efficient multidimensional energy dissipation performance. Utility Model Content

[0004] The purpose of this invention is to provide a cross-plate type tension-compression energy dissipation bearing, which solves the technical problems of traditional shock-absorbing bearings, such as difficulty in balancing vertical tension-compression performance and energy dissipation capacity, low energy dissipation efficiency due to multi-directional coupling, and limited durability and fatigue performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A cross-shaped insert-type tension-compression energy dissipation support includes an upper connecting assembly, a lower connecting assembly, an organic polymer material layer, and a lead core. The upper connecting assembly includes an upper connecting plate and a cross steel plate fixed to the lower surface of the upper connecting plate. The lower connecting assembly includes a lower connecting plate and stiffening ribs fixed to the upper surface of the lower connecting plate. Multiple stiffening ribs are arranged at intervals. The cross steel plate is inserted into the gaps between the multiple stiffening ribs, with a gap between the lower end of the cross steel plate and the lower connecting plate, and a gap between the upper connecting plate and the top of the stiffening ribs. A void is left between the cross steel plate and the corresponding stiffening rib. The organic polymer material layer fills the voids between the cross steel plate and the stiffening ribs. Perforations are pre-drilled on the surfaces where the cross steel plate, stiffening ribs, and organic polymer material layers are stacked. There are multiple lead cores, and each lead core vertically penetrates the pre-set perforations in the cross steel plate, stiffening ribs and organic polymer material layer. The top of the upper connecting plate and the bottom of the lower connecting plate are both fixed with anchor rods for connecting to the external structure.

[0007] Preferably, there are four stiffening ribs, and the four stiffening ribs form a cross-shaped gap that matches the shape of the cross steel plate; the cross steel plate is inserted into the cross-shaped gap; the gap between the cross steel plate and the corresponding stiffening rib is L-shaped; the organic polymer material layer is disposed in the L-shaped gap.

[0008] Preferably, the anchor bolt is provided with anchor bolt stiffening ribs at the connection points between the anchor bolt and the upper connecting plate and the lower connecting plate.

[0009] Preferably, the anchor rod is fixed to the upper connecting plate and the lower connecting plate by welding.

[0010] Preferably, the distance between the cross steel plate and the lower connecting plate is 20mm~50mm.

[0011] Preferably, the distance between the stiffening rib and the upper connecting plate is 20mm~50mm.

[0012] Preferably, the lead core is a cylindrical lead component. Compared with the prior art, the present invention has the following features and beneficial effects.

[0013] 1. The cross-plate type tension-compression energy-dissipating bearing provided by this utility model innovatively integrates high vertical tension-compression bearing capacity with efficient multi-dimensional energy dissipation through the combination of a "cross steel plate-stiffening rib" interlocking structure and a lead core and organic polymer material layer, effectively solving the technical problem of traditional bearings that are difficult to balance tensile strength and energy dissipation. This bearing has the characteristics of high vertical stiffness, high energy dissipation efficiency, reliable tensile performance and good durability, and is especially suitable for complex engineering scenarios with extremely high requirements for vertical stress performance and seismic performance, such as long-span bridges, stadiums, and super high-rise buildings.

[0014] 2. Compared with existing damping components, the bearing of this utility model significantly enhances the safety and stability of the structure under dynamic loads such as earthquakes through the synergistic work of rigid structure and flexible energy-dissipating material. Its structural design enables the bearing to effectively control vertical deformation, provide sufficient tensile bearing capacity, and efficiently dissipate energy. At the same time, its components are easy to process and convenient to install, achieving both high performance and good economy, with obvious comprehensive advantages.

[0015] 3. This utility model uses a rigid mechanical interlocking structure formed by inserting cross steel plates into stiffening ribs, which greatly improves the bearing capacity and stiffness of the support under vertical pressure and tension, and can effectively control structural deformation. At the same time, the insertion and cooperation between the cross steel plates and stiffening ribs is itself a horizontal limiting mechanism, which can limit the excessive horizontal displacement of the support, improve the overall stability of the structure, and has a built-in horizontal limiting function.

[0016] 4. In the support of this utility model, the lead core undergoes shear yielding under earthquake or wind vibration, efficiently dissipating energy; at the same time, the organic polymer material layer provides viscoelastic damping and assists in energy dissipation; the two work together to attenuate the vibration response of the structure.

[0017] 5. This utility model has a reasonable structure, avoiding stress concentration. The stiffening ribs and anchor stiffening ribs strengthen key parts, preventing local instability and fatigue failure, and ensuring the reliability of the support under long-term use and rare earthquakes. Furthermore, the overall structure of the support is compact, the force transmission path is clear, and manufacturing and installation are convenient. While achieving excellent performance, it also has a high performance-price ratio. Attached Figure Description

[0025] like Figure 1-5 As shown, this cross-shaped insert-type tension-compression energy-dissipating support includes an upper connecting assembly 1, a lower connecting assembly 2, an organic polymer material layer 3, and a lead core 4. The upper connecting assembly 1 includes an upper connecting plate 1.1 and a cross steel plate 1.2 fixed to the lower surface of the upper connecting plate 1.1. The lower connecting assembly 2 includes a lower connecting plate 2.1 and stiffening ribs 2.2 fixed to the upper surface of the lower connecting plate 2.1. There are multiple stiffening ribs 2.2, which are arranged at intervals. The cross steel plate 1.2 is inserted into the gaps between the multiple stiffening ribs 2.2, and a gap is left between the lower end of the cross steel plate 1.2 and the lower connecting plate 2.1, and a gap is left between the upper connecting plate 1.1 and the top of the stiffening rib 2.2. A gap is left between the cross steel plate 1.2 and the corresponding stiffening rib 2.2. The organic polymer material layer 3 fills the gaps between the cross steel plate 1.2 and the stiffening rib 2.2. Perforations are pre-drilled on the surfaces where the cross steel plate 1.2, stiffening rib 2.2, and organic polymer material layer 3 are stacked. There are multiple lead cores 4, and each lead core 4 vertically penetrates the pre-set perforations in the cross steel plate 1.2, stiffening rib 2.2 and organic polymer material layer 3; Anchor rods 5 for connecting to external structures are fixed to the top of the upper connecting plate 1.1 and the bottom of the lower connecting plate 2.1.

[0026] In this embodiment, there are four stiffening ribs 2.2, and the four stiffening ribs 2.2 form a cross-shaped gap that matches the shape of the cross steel plate 1.2; the cross steel plate 1.2 is inserted into the cross-shaped gap; the gap between the cross steel plate 1.2 and the corresponding stiffening rib 2.2 is L-shaped; the organic polymer material layer 3 is disposed in the L-shaped gap.

[0027] In this embodiment, anchor rod stiffening ribs 5.1 are respectively provided at the connection points between the anchor rod 5 and the upper connecting plate 1.1 and the lower connecting plate 2.1.

[0028] In this embodiment, the anchor rod 5 is fixed to the upper connecting plate 1.1 and the lower connecting plate 2.1 by welding.

[0029] In this embodiment, the distance between the cross steel plate 1.2 and the lower connecting plate 2.1 is 20mm~50mm.

[0030] In this embodiment, the distance between the stiffening rib 2.2 and the upper connecting plate 1.1 is 20mm~50mm.

[0031] In this embodiment, the organic polymer material layer 3 is a rubber layer, a polyurethane layer, or a combination layer of rubber and plastic.

[0032] In this embodiment, the lead core 4 is a cylindrical lead component.

[0033] The manufacturing method of this cross-shaped insert type tension and compression energy dissipation support includes the following steps.

[0034] S1: Make the upper connecting component 1 and the lower connecting component 2 respectively.

[0035] S2: Treat the surfaces of the cross steel plate 1.2 and stiffening rib 2.2, such as by sandblasting or cleaning.

[0036] S3: Install organic polymer material layer 3: Install organic polymer material layer 3 in the cross-shaped gap formed by stiffening ribs 2.2, and make each organic polymer material layer 3 attached to the corresponding external corner of stiffening rib 2.2.

[0037] S4: Insert the cross steel plate 1.2 into the gap formed by the organic polymer material layer 3.

[0038] S5: Press lead core 4 into the perforation of the combination of upper connecting component 1, lower connecting component 2 and organic polymer material layer 3. The tension and compression energy dissipation support is now complete.

[0039] In this embodiment, there are rectangular gaps between the horizontally and vertically adjacent stiffening ribs 2.2, forming a cross-shaped gap.

[0040] In this embodiment, the cross-shaped insert type tension-compression energy dissipation bearing has its upper connecting component 1 connected to the superstructure (such as the upper box girder of a bridge or the column base of a building) via anchor rods 5 on the upper connecting plate 1.1. The lower connecting component 2 is connected to the lower structure (such as a bridge pier or foundation) via anchor rods 5 on the lower connecting plate 2.1.

[0041] When the structure is subjected to vertical pressure, the load is transferred through the cross steel plate 1.2 to the surrounding stiffening ribs 2.2, the organic polymer material layer 3, and the lead core 4, and finally to the lower connecting plate 2.1. Due to the rigid frame formed by the cross steel plate 1.2 and the stiffening ribs 2.2, the support exhibits high vertical compressive stiffness.

[0042] When the structure is subjected to vertical tensile force, the cross steel plate 1.2 will hold the upper part of the stiffening rib 2.2 through the organic polymer material layer 3 and the lead core 4, forming an effective tensile force transmission mechanism and avoiding the problem of traditional supports being easily pulled out.

[0043] When the structure undergoes horizontal deformation, such as during an earthquake, there is a tendency for relative movement between the cross-shaped steel plate 1.2 and the stiffening rib 2.2. This movement is influenced by two factors: first, the lead core 4 undergoes shear plastic deformation, dissipating a large amount of seismic energy; second, the organic polymer material layer 3 undergoes shear elastic deformation, providing restoring force and simultaneously dissipating energy through viscous effects. The range of movement of the cross-shaped steel plate within the gap is restricted by the stiffening ribs, thus achieving a horizontal restraint function.

[0044] The above embodiments are not exhaustive examples of specific implementation methods, and other embodiments may also exist. The purpose of the above embodiments is to illustrate the present utility model, rather than to limit the protection scope of the present utility model. All applications derived from simple variations of the present utility model fall within the protection scope of the present utility model.
