Novel shock absorption self-resetting energy-consuming inhaul cable supporting device

Abstract

The invention discloses a novel shock absorption self-resetting energy-consuming inhaul cable supporting device, and belongs to the technical field of shock absorption equipment. The novel shock absorption self-resetting energy-consuming inhaul cable supporting device is composed of a resetting mechanism, resetting energy-consuming mechanisms, force-limiting energy-consuming mechanisms, high-strength steel cables and bases. The resetting mechanism is arranged between the two bases, and the resetting energy-consuming mechanisms are arranged on both sides of the resetting mechanism. The force-limiting energy-consuming mechanisms are arranged on the outer sides of the resetting energy-consuming mechanisms in a connecting mode, and the high-strength steel cables are arranged on the outer sidesof the force-limiting energy-consuming mechanisms in a connecting mode. According to the novel shock absorption self-resetting energy-consuming inhaul cable supporting device, the self-resetting ability of the supporting is improved, the selection range of a pre-stressed reset bar material is widened, the increase of the supporting internal force under the action of exceeding the fortification intensity earthquake is effectively suppressed, the energy-consuming ability is improved, so that main structural elements, such as beams and columns, are strengthened, the insufficiency that an existing reset reinforcement material-fiber reinforced composite material can not bend at a pulley position is overcome, the utilization ratio of the self-reset mechanism is improved, and the economic cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of shock absorbing equipment, and relates to a self-resetting energy-consuming cable support device, in particular to a device with self-resetting, force limiting, energy consumption, and protection for the main structure, which is suitable for engineering shock absorption. Cable support device. Background technique [0002] As an efficient anti-lateral force system, braced frames are widely used in the field of engineering seismic resistance, and the performance of the brace directly determines the seismic performance of the system. However, the traditional bracing frame system often produces large unrecoverable deformation after strong earthquakes, which seriously endangers the safety of buildings, and the repair is difficult and expensive. [0003] Self-resetting support is a relatively novel support form, which can effectively solve the problem that the existing support structure is difficult to repair ...
