Damping type hinge pin support

Abstract

The invention relates to a damping type hinge pin support which has a great capacity for energy dissipation and damping and has high flexural rigidity, shear stiffness and deformability. The damping type hinge pin support comprises an upper cover plate, a pair of lower lug plates, a hinge pin and a bottom plate, and further comprises an upper lug plate with a chamber and a pair of high damping rubber combination spring bodies with shaft holes, wherein end faces of the pair of the high damping rubber combination spring bodies are respectively provided with a teflon layer. The damping type hinge pin support solves the problem that in the prior art, a hinge pin support of a steel structure is poor in resistance in acting force caused by temperature variation and multidirectional earthquake acting force, is capable of rotating in a multidirectional mode, meanwhile has high pulling, pressing and bearing force inside a support plane in the main stress direction and especially has high deformability and energy dissipation and damping capacity.

Description

technical field [0001] The invention relates to a shock-absorbing pin bearing, which is suitable for the bottom and lateral joints of large-span space building structures. Background technique [0002] The pin shaft support that uses at present is steel structure pin shaft support, and it is made up of upper cover plate, upper lug plate, pin shaft, a pair of lower lug plate and base plate, and upper and lower lug plate is hinged by pin shaft. The above-mentioned steel structure pin shaft support can freely rotate in the direction of the plane of the support with the pin shaft as the rotation axis. [0003] The disadvantage of the above-mentioned steel structure pin shaft support is that its parts are made of steel and cannot rotate outside the plane of the support (that is, on the side), so the bearing capacity and deformation adaptability outside the plane of the support cannot be guaranteed. Uncertain loads outside the seat plane (such as caused by earthquakes or temperat...

[0003] The disadvantage of the above-mentioned steel structure pin shaft support is that its parts are made of steel and cannot rotate outside the plane of the support (that is, on the side), so the bearing capacity and deformation adaptability outside the plane of the support cannot be guaranteed. Uncertain loads outside the seat plane (such as caused by earthquakes or temperature changes), the lugs are easily broken, causing safety hazards
