Description
技术领域technical field
本实用新型涉及装配整体式减震支撑，属于土木工程结构消能减震（振）技术领域。The utility model relates to an assembled integral shock-absorbing support, which belongs to the technical field of energy-dissipating shock-absorbing (vibration) of civil engineering structures.
背景技术Background technique
防屈曲支撑是一种常见的消能减震装置，在建筑工程领域得到了较为广泛的应用。普通支撑在大震作用下屈曲失稳，接近于受弯机制。防屈曲支撑的外包约束构件限制支撑的弯曲变形，使支撑主要承受轴向力，并在拉压时均能屈服耗能。这种拉压同性使得防屈曲支撑体系较之普通支撑框架具有造价低、结构安全度高以及结构设计灵活等优点。但防屈曲支撑本身也存在局限性。中/大震下防屈曲支撑耗能性能优良，但在小震及微振下，防屈曲支撑仍处于弹性阶段不耗能。这样对于侧移、舒适度要求高的高层建筑和高耸结构来说，防屈曲支撑体系就不能满足要求。The anti-buckling brace is a common energy dissipation and shock absorption device, which has been widely used in the field of construction engineering. Ordinary supports buckle and become unstable under large earthquakes, which is close to the bending mechanism. The outsourcing constraining members of the anti-buckling support limit the bending deformation of the support, so that the support mainly bears the axial force, and can yield and dissipate energy in both tension and compression. This isotropy of tension and compression makes the buckling-resistant bracing system have the advantages of low cost, high structural safety and flexible structural design compared with ordinary bracing frames. But buckling-resistant braces have their own limitations. The buckling-resistant braces have excellent energy dissipation performance under moderate/large earthquakes, but under small and micro-vibrations, the buckling-resistant braces are still in the elastic stage and do not consume energy. In this way, for high-rise buildings and high-rise structures with high requirements for lateral displacement and comfort, the anti-buckling support system cannot meet the requirements.
黏弹性阻尼器由黏弹性阻尼材料与钢板叠合黏结而成，依靠黏弹性材料的剪切滞回耗能特性，给主体结构提供附加刚度和阻尼，减少主体结构的动力反应，达到减振的效果。黏弹性阻尼器性能可靠、构造简单、耗能能力强，并且能全阶段耗能，不像防屈曲支撑那样需要较大的相对位移才能屈服变形发挥耗能作用。The viscoelastic damper is composed of a viscoelastic damping material and a steel plate laminated and bonded. Relying on the shear hysteretic energy dissipation characteristics of the viscoelastic material, it provides additional stiffness and damping to the main structure, reduces the dynamic response of the main structure, and achieves the effect of vibration reduction. Effect. The viscoelastic damper has reliable performance, simple structure, strong energy dissipation capacity, and can dissipate energy at all stages. Unlike the anti-buckling support, it requires a large relative displacement to yield and deform to exert energy dissipation.
有研究人员提出综合利用不同耗能原理或机制来设计新型耗能减震器，即耗能器同时利用两种或两种以上方式耗能的思想，研究开发了多种新型耗能减振器。Some researchers have proposed to design new energy-dissipating shock absorbers by comprehensively utilizing different energy-dissipating principles or mechanisms, that is, the idea that energy-dissipating devices use two or more ways to consume energy at the same time, and have researched and developed a variety of new energy-dissipating shock absorbers. .
近年来有工程人员提出防屈曲支撑与黏弹性阻尼器并联结合的受力机理。一种制作方法是黏弹性材料一面与芯材黏贴，一面与剪切钢板黏贴。剪切钢板同时也作为外包约束构件。芯材在轴向力作用下产生变形，同时带动黏弹性材料产生剪切变形而耗能，这样可以实现防屈曲支撑在变形较小时耗能。这种制作方式存在较大缺陷。一方面，剪切变形不均匀，中间小两头大，支撑中部黏弹性材料剪切变形会远小于两端处黏弹性材料的剪切变形，这样对于黏弹性材料的利用效果较差。另一方面，黏弹性材料与钢板的黏贴需要经过高温硫化，将支撑的芯材整体入炉加热既不方便又影响低周疲劳性能。此外，芯材在塑性条件下变形较大，再加上黏弹性材料剪切变形不均匀，容易造成黏弹性材料的撕裂。In recent years, engineers have proposed the stress mechanism of the parallel combination of anti-buckling braces and viscoelastic dampers. One manufacturing method is that one side of the viscoelastic material is glued to the core material, and the other side is glued to the sheared steel plate. Shear steel plates also serve as outer restraint members. The core material deforms under the action of the axial force, and at the same time drives the viscoelastic material to generate shear deformation and consume energy, so that the anti-buckling support can consume energy when the deformation is small. There is bigger defect in this way of making. On the one hand, the shear deformation is uneven, the middle is small and the two ends are large, the shear deformation of the viscoelastic material in the middle of the support will be much smaller than the shear deformation of the viscoelastic material at the two ends, so the utilization effect of the viscoelastic material is poor. On the other hand, the bonding of the viscoelastic material to the steel plate needs to be vulcanized at high temperature. It is inconvenient to put the supporting core material into the furnace for heating, and it will affect the low cycle fatigue performance. In addition, the core material deforms greatly under plastic conditions, and the shear deformation of the viscoelastic material is uneven, which easily causes the tearing of the viscoelastic material.
还有一种制作方法是黏弹性材料两面分别黏贴于两块剪切钢板，内侧剪切钢板紧挨着芯材，与芯材于端部焊接在一起。外侧剪切钢板同时也作为防屈曲支撑的外包约束构件。这样虽然避免了前一种制作方法带来了上述三个方面的问题，但也有不足之处。一方面，为了满足黏弹性材料剪切变形的需要，外包约束构件内部预留了一定空间，这样就不能对芯材屈服段在全长范围内进行屈曲约束，从而形成明显薄弱点。另一方面，考虑到安全性与经济性，芯材拉/压应变达到设计值时，黏弹性材料剪切变形应接近极限剪切变形；芯材处于弹性阶段时，黏弹性材料剪切变形较小，耗散的能量有限，材料利用率也较低。Another manufacturing method is that the two sides of the viscoelastic material are respectively pasted on two shearing steel plates, and the inner shearing steel plate is next to the core material, and is welded together with the core material at the end. The outer shear steel plates also serve as the outer restraint members of the buckling brace. Although avoiding the above-mentioned three aspects problems brought by the previous production method like this, there are also weak points. On the one hand, in order to meet the needs of shear deformation of viscoelastic materials, a certain space is reserved inside the outer restraint member, so that buckling restraint cannot be performed on the yield section of the core material throughout the entire length, thus forming an obvious weak point. On the other hand, considering safety and economy, when the tensile/compressive strain of the core material reaches the design value, the shear deformation of the viscoelastic material should be close to the ultimate shear deformation; when the core material is in the elastic stage, the shear deformation of the viscoelastic material is relatively small Small, the energy dissipated is limited, and the material utilization rate is also low.

本实用新型的目的在于从工作机理和构造形式上克服上述缺陷，提出一种装配整体式减震支撑。其工作机理为带有限位功能的黏弹性阻尼元件与弹簧构件串联之后再与防屈曲支撑并联。当装配整体式减震支撑整体变形较小时，防屈曲支撑元件的耗能芯材处于弹性阶段不耗能，黏弹性阻尼元件剪切变形耗能；当装配整体式减震支撑整体变形较大时，耗能芯材屈服耗能，挡板将黏弹性材料的剪切变形限制在许可变形范围内，而弹簧承担大部分变形。黏弹性阻尼元件与防屈曲支撑元件协同工作，小变形时由黏弹性阻尼元件耗能，大变形时主要由防屈曲支撑元件耗能。The purpose of this utility model is to overcome the above-mentioned defects in terms of working mechanism and structural form, and propose an assembled integral shock-absorbing support.

The viscoelastic damping element and the anti-buckling support element work together, and the energy is dissipated by the viscoelastic damping element when the deformation is small, and the energy is mainly dissipated by the anti-buckling support element when the deformation is large.

Other cross-section forms can also be used in actual engineering. The space between the I-shaped outer sleeve welded by the steel plate and the non-adhesive layer 6 is filled with fine stone concrete to form the outer restraint member 7 . Bolt holes are reserved on the flange of the I-shaped outer sleeve, and are connected with the bottom plate bolts of the viscoelastic damping element. The cover plate 10 and the baffle plate 13 are welded by steel plates, and the viscoelastic material is placed between the cover plate 10 and the bottom plate 11 , and they are vulcanized and pasted together in a furnace at high temperature to form the viscoelastic damping element 3 . Bolt holes are reserved in the bottom plate 11 to be bolted to the outer constraining member, and bolt holes are reserved in the baffle plate 13 to be connected to the partition plate 14 by bolts. One end of the spring 12 is connected to the partition plate 14 , and the other end is connected to the supporting end plate 8 . The buckling support element 2, the viscoelastic damping element 3, and the limit device 4 are processed separately and assembled into a whole through bolted connections to form the assembled integral damping support 1 described in the present invention.
