Torsion-prevention shock-insulation tensile structure for construction projects

Abstract

The invention discloses a torsion-prevention shock-insulation tensile structure for construction projects. The torsion-prevention shock-insulation tensile structure is arranged between a lower construction structure and an upper construction structure, and comprises an upper buttress, a lower buttress, a shock-insulation support, a first shock-insulation device, a second shock-insulation device, a third shock-insulation device, a fourth shock-insulation device and a sliding device. The first shock-insulation device comprises a first fixing frame, a first transverse rod, a first spring, a second spring, a second transverse rod and a first connecting rod. The second shock-insulation device comprises a second fixing frame, a third fixing frame, a first ejection rod, a third transverse rod, a third spring, a fourth spring, a fourth transverse rod, a fourth fixing frame and a fifth fixing frame. The third shock-insulation device comprises a fifth transverse rod, a first steel wire, a sixth transverse rod, a second ejection rod, a fifth spring, a sixth spring, a first supporting rod, a second connecting rod and a second supporting rod. The torsion-prevention shock-insulation tensile structure can solve the problem that a laminated rubber shock-insulation support is not good in tensile capacity, and can ensure the horizontal freedom degree and vertical freedom degree of the laminated rubber shock-insulation support.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an anti-torsion, shock-isolation and tension-resistant structure for construction engineering. 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 seismic isolation bearings in high-rise buildings are likely to have tensile stress, while the engineering is more Commonly used laminated rubber bearings have a low tensil...

AI Technical Summary

Problems solved by technology

The existing peripheral tensile device has the problem of coupling the horizontal degree of freedom and the vertical degree of freedom of the isolation support. The existence of the tensile device also affects the horizontal shock absorption coefficient of the isolation support. The existing separate Although the tensile device alleviates this effect to a certain extent, it cannot fully limit the tensile displacement of the seismic isolation bearing due to a certain distance from the seismic isolation bearing. Insufficient capacity has become an urgent problem to be solved
