Description

Technical Field

[0001] The utility model relates to the technical field of building shock absorption and isolation, in particular to a tensile device with a buffer device used in conjunction with a shock isolation layer. Background Art

[0002] With the development of the global economy and the acceleration of urbanization, high-rise and super-high-rise buildings have appeared frequently. Base isolation is a simple and effective shock absorption technology that has been widely used in various low-rise and medium-rise buildings and has achieved good shock absorption effects. In recent years, this technology has been gradually promoted and applied to high-rise and super-high-rise buildings. Due to the large overturning moment generated by the horizontal seismic force of high-rise and super-high-rise buildings, rubber isolation bearings are prone to tension under strong earthquake motion. Under strong earthquake motion, structures with large aspect ratios will produce obvious bumps and shakes, which will make the tension phenomenon of rubber isolation bearings more obvious. When the rubber isolation bearing is subjected to axial tension, although it does not appear to be damaged much from the appearance, it is easy to form a negative pressure state inside and produce many pores. Studies have shown that after the rubber isolation bearing is subjected to large tensile deformation and then compressed, its vertical compressive stiffness is reduced to about 1 / 2 of the initial stiffness, and when the tensile stress reaches 1.5-3.0MPa, the tensile stiffness of the bearing will drop sharply, showing a bilinear characteristic. The tensile device can improve the vertical tensile resistance of the seismic isolation layer. The tensile device will bring a great impact when subjected to tension, and the existing tensile device cannot buffer the impact load, thereby affecting the tensile performance. Therefore, the utility model provides a tensile device with a buffer device used in conjunction with the seismic isolation layer. Utility Model Content

[0003] The utility model aims at the deficiencies of the prior art and provides a tensile device with a simple structure, convenient installation and strong tensile resistance. The tensile fastener is set to be bidirectional, a buffer is set in the middle of the tensile fastener, and the tensile device is installed at the place where the seismic isolation layer is subjected to a large tensile force. At the same time, a buffer is added to the contact part of the tensile fastener of the tensile device to buffer the impact load.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A tensile device with a buffer device used in conjunction with a seismic isolation layer, comprising an upper tensile fastener and a lower tensile fastener, wherein the upper tensile fastener and the lower tensile fastener are respectively fixedly arranged at the upper and lower parts of the seismic isolation layer of a building, the upper tensile fastener and the lower tensile fastener are arranged in a cross shape, limited stop strips are arranged on the opposite surfaces of the upper tensile fastener and the lower tensile fastener, and a buffer is arranged between the upper tensile fastener and the lower tensile fastener, and the buffer is located on the inner side of the limited stop strip.

[0006] Furthermore, both sides of the lower tensile fastener are connected to the upper part of the seismic isolation layer of the building through an upper connecting assembly.

[0011] Furthermore, the elastic component is a butterfly spring, rubber or polyurethane.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The anti-tension device of the utility model can be used in conjunction with the seismic isolation rubber bearing to exert the synergistic effect of the two. The seismic isolation rubber bearing in the seismic isolation layer can provide a large energy dissipation capacity, and the anti-tension device can improve the vertical tensile resistance of the seismic isolation layer. In order to avoid a large impact when the anti-tension device is subjected to tension, a buffer is added to the contact part of the anti-tension fastener of the anti-tension device to buffer the impact load. The buffer is a butterfly spring, which is simple, low-cost and can effectively buffer the impact load. BRIEF DESCRIPTION OF THE DRAWINGS
