Description
Technical Field
The invention relates to a vibration isolation support, in particular to a vertical self-tensile laminated rubber vibration isolation support and a construction method thereof.
Background
Earthquake is one of important natural disasters seriously jeopardizing human survival, and has unpredictability and burstiness. The foundation vibration isolation is to set a vibration isolation layer between the building foundation and the upper structure, so that the deformation is mainly concentrated on the vibration isolation layer, the basic period of the structure is prolonged, and the transmission of the earthquake energy to the upper structure is reduced, thereby greatly reducing the vibration response of the upper structure component under the earthquake and improving the safety performance of the building. The laminated rubber shock insulation support is a device with high vertical bearing capacity, small horizontal rigidity and larger horizontal lateral movement tolerance value, can reduce the horizontal earthquake action and bear the vertical earthquake action, and is the shock insulation device most applied in the current engineering.
The laminated rubber shock insulation support is manufactured according to different laminated structures and processes, wherein an upper connecting cover plate is connected with a building upper structure, and a lower connecting cover plate is connected with a building foundation so as to transmit horizontal shearing force. The laminated rubber shock insulation support adopts a layer of thin rubber and a layer of thin steel plate to be overlapped alternately, and the tensile capacity of the rubber support is far smaller than the compressive capacity due to the difference of restraining the transverse deformation capacity. The tensile rigidity of the laminated rubber shock insulation support is smaller than the compressive rigidity, the tensile capability of the support is poorer, and the tensile stress reaches 1-2MPa, namely yield; the vertical rigidity of the rubber support is relatively large compared with the horizontal rigidity, and the possibility of amplifying the earthquake action exists, so that the support is easy to generate tensile stress. When the internal tensile stress of the shock insulation support exceeds the limit during earthquake action, the building is likely to overturn integrally, so that the limit tensile stress of the rubber support is definitely not lower than 1MPa in GB50010 of building anti-seismic design Specification in China. For the rubber support shock insulation structure, when the structure height and width are larger or the vertical earthquake action is larger, the situation that the laminated rubber shock insulation support is pulled inevitably occurs, so that the shock insulation support is damaged, and the application of the laminated rubber shock insulation support in high-rise buildings with larger height and width and high intensity areas is severely restricted due to insufficient tensile capacity of the laminated rubber shock insulation support.
In order to solve the problem of insufficient tensile property of the laminated rubber shock insulation support, a tensile limiting device is generally adopted in the prior art. The tensile limiting device mainly has two types: the tensile limiting device and the shock insulation support are integrated, the mode of combined use of the rubber support and the tensile shock insulation support is mainly adopted, the support and elastic devices such as the disc springs can be connected in series for further reducing the vertical rigidity of the support, the tensile shock insulation support of the type has the function of limiting the tensile deformation of the shock insulation support, the implementation difficulty is high, the horizontal rigidity of the support is increased, and the horizontal shock absorption effect can be influenced. The other type is that components with horizontal vibration isolation and vertical tensile force independent of each other are used in a combined mode to form a composite tensile vibration isolation support, a tensile limiting device is independently arranged near the vibration isolation support, and the tensile deformation of the vibration isolation support under the earthquake action is limited by optimizing the rigidity and the connection clearance value of the tensile limiting device, so that the horizontal performance of the vibration isolation support is not affected by the tensile limiting device. The tensile limiting device not only needs to meet the requirements of vertical tensile rigidity and bearing capacity, but also needs to adapt to the deformation of the shock insulation layer in the horizontal direction, so that the size is large, the use of the original building functions is affected, and only a small amount of arrangement is realized. Especially when the shock insulation structure is located near the shock-generating fracture zone, the vertical earthquake effect of the structure is larger, and besides the peripheral laminated rubber shock insulation support, the middle laminated rubber shock insulation support is easy to generate tensile stress, so that the two schemes are difficult to implement.
The tensile shock insulation support requires the support to have the functions of horizontal shock insulation and vertical tensile resistance, so the design needs to be considered: the bearing capacity of the support is ensured; horizontal shock insulation and reset capability of the post-shock support; and the support realizes the tensile function. In order to fully exert the performance of the laminated rubber vibration isolation support and avoid the laminated rubber vibration isolation support from bearing unfavorable tensile force, a device for preventing the laminated rubber vibration isolation support from being vertically pulled is urgently needed.
