Anti-torsion integrated shock insulation support anti-tension device

Abstract

An anti-torsion integrated shock insulation support anti-tension device comprises an upper supporting piece, an anti-tension piece, an anti-swinging piece, a vertical connecting piece and a flexible limiting device. The upper supporting piece is of a rectangular horizontal flat board structure, the center of the upper supporting piece is fixed to an upper buttress of a shock insulation support, and the periphery of the upper supporting piece extends into a cavity formed by the upper end of the vertical connecting piece, the anti-tension piece and the anti-swinging piece, wherein an opening is formed in the side face of the cavity. Rolling steel beads of the anti-tension piece and the anti-swinging piece are inlaid into the inner surface of the cavity so that a sliding structure can be formed. A certain distance is maintained between the sliding structure and the upper supporting piece vertically. The flexible limiting device is fixed to the inner end of the cavity, wherein the flexible limiting device and the upper supporting piece are arranged at the same height in parallel symmetrically. The lower end of the vertical connecting piece is fixed to a lower construction structure. According to the anti-torsion integrated shock insulation support anti-tension device, stretching displacement of the shock insulation support is thoroughly limited and the shock reduction efficiency of the shock insulation support is not affected; torsional deformation of the shock insulation support is controlled by the flexible limiting device and the stability of the shock insulation support is improved. According to the anti-torsion integrated shock insulation support anti-tension device, the structure is simple, materials are easy to obtain, machining is convenient, and the project practical value is large.

Description

technical field [0001] The invention relates to a vibration damping control device of a building structure, in particular to an anti-twist integrated anti-twist anti-tension device of an anti-twist support. Background technique [0002] Due to the advantages of clear concept, obvious effect, and significant economic benefits, the seismic isolation technology of building structures has been widely used and has withstood the test of actual earthquakes. With the deepening of research, more and more high-rise buildings and irregular buildings are used. Using shock isolation technology. [0003] Compared with multi-storey buildings, the overturning effect of high-rise buildings under horizontal earthquakes is more obvious. After adopting seismic isolation technology, when subjected to large earthquakes, the isolation bearings in high-rise buildings are likely to have tensile stress, while the engineering The tensile capacity of the commonly used laminated rubber bearing is low, ...
